Zainab Abbas Abd, Aqeel Mohammad Majeed, Zaid Raad Abbas, pages 291-295

Read Abstract

 Background: Pseudomonas aeruginosa is known for its flexibility and importance as both a pathogen and a model organism for genetic studies. This investigation was conducted to detect L-arginase enzyme gene sequences from Paeruginosa in soil and sewage samples.

Methods: Soil and sewage samples were collected from different regions in Iraq for six months, from November 2022 to April 2023. Pseudomonas aeruginosa was isolated by culturing samples on nutrient medium and McConkey agar medium. Gram stains and biochemical tests were performed to identify the isolates, and the VITEK 2 system was used to confirm the identity of P. aeruginosa. DNA was extracted from the P. aeruginosa isolates and used for molecular identification by amplifying and sequencing the 16S rRNA gene. Also, the L-arginase gene sequences were amplified using the PARG1 and PARG2 primers.

Results: Out of 52 soil and sewage samples, 33 isolates (63.5%) of P. aeruginosa were identified, including 15 (28.8%) from soil and 18 (34.6%) from sewage. Among these, 9 (60.0%) of the soil isolates and 12 (66.7%) of the sewage isolates produced L-arginase.

Conclusion: The present study's findings revealed presence of the L-arginase enzyme from P. aeruginosa isolates derived from soil and wastewater samples. This research is considered a crucial step toward understanding the genetic structure and functions of L-arginase in P. aeruginosa, providing insights for future scientific investigations.

Muhammad Hermawan Widyananda, Rahmat Grahadi, Ichda Arini Dinana, Arif Nur Muhammad Ansori, Viol Dhea Kharisma, Vikash Jakhmola, Maksim Rebezov, Marina Derkho, Pavel Burkov, Pavel Scherbakov, Rahadian Zainul, pages 296-303

Read Abstract

 Background: WHO in 2019 announced that atherosclerosis is included in the top leading cause of mortality, which is more than 32% of deaths worldwide. The most common early symptom of atherosclerosis is the formation of foam cells inside blood vessel wall. Fatty acids from Chlorella vulgaris have the potential to inhibit foam cell formation. The purpose of this study is to analyze the inhibitory activity of fatty acids from C. vulgaris towards various proteins involved in foam cell formation.

Methods: The fatty acids content of C. vulgaris was determined based on previous research. The molecular samples of fatty acids and proteins including CETP, LOX1, ACAT1, and CD36 were obtained from the PubChem and RCSB PDB databases. Drug-likeness and probable activity screening were conducted using the SWISS ADME and PASS Online web servers. Molecular docking was performed using AutoDock Vina, which is integrated into the PyRx software.

Results: All fatty acids comply with the Lipinski rule of five. Thirteen fatty acids were predicted to have anti-atherosclerosis activity based on PASS online screening: myristoleic acid, hexadecadienoic acid, linolenic acid, palmitoleic acid, linoleic acid, heptadecenoic acid, oleic acid, eicosadienoic acid, nonadecenoic acid, gadoleic acid, heneicosanoic acid, brassidic acid, and nervonic acid. Molecular docking simulation results showed that Nervonic acid binds to CETP, LOX1, and ACAT1 in the same site as an inhibitor with the lowest binding affinity value (-5.9, -7, and -7.8 kcal/mol). Hexadecadienoic acid binds to CD36 with the lowest binding affinity value (-4.9 kcal/mol) and binds in the same site with inhibitor.

Conclusion: Therefore, nervonic acid and hexadecadienoic acid have a high potential as a foam cell formation inhibitor.

Quantitative analysis of biofuel MET6 expression level in a treated Saccharomyces cerevisiae with garlic (Allium sativum L.) extract

Alawiah Mohammad Alhebshi, Nouf Khalid Al-Qahtani, pages 304-311

Read Abstract

 Background: Methionine and cysteine are the common sulfur-containing amino acids integrated into proteins. However, methionine is the immediate initiating amino acid in biosynthesis of almost all eukaryotic proteins. Metabolism of methionine initiates with activating S-adenosylmethionine, where this cofactor plays numerous roles in transfer methyl group pathways. There are various biosynthetic paths of methionine, in fungi, the ultimate step of methionine biosynthesis is mediated by cobalamin-independent methionine synthase (MET6). Chemically produced methionine is widely used in various applications. However, the issue is the sulfur source, which is typically supplied as inorganic sulfate, which needs to be reduced to create methionine.

Methods:  Herein, testing the novel hypothesis that using natural resources such as garlic (Allium sativum), which is rich in organosulfur nitrogen-containing compounds, might enhance the biosynthesis of methionine. A quantitative analysis of MET6 mRNA was performed using qRT-PCR in all groups for treated S. cerevisiae (WT-BY4742) and met15Δ mutant strains with and without garlic extract.

Results: In this study, according to the two-way ANOVA test, Met6 expression level was up-regulated significantly after 2 hours garlic exposure, and a significant increase in cell growth was observed of both mutant and wild-type strains compared with untreated control.

Conclusion: It is concluded that garlic is a prominent natural source that may stimulate methionine biosynthesis, and this may be due to its organosulfur-containing compounds. Such plant sources could offer new natural approaches for methionine production and also support the prevention of certain diseases.

Targeting BCL-2 in Hematological Cancers: Computational Screening of Cucurbitacins as Promising Inhibitors

Fatemah Abdulaziz Alhakami, pages 312-316

Read Abstract

 Background: Disrupting the balance between cell proliferation and death is critical in cancer formation. Increased resistance to apoptosis, which is frequently caused by BCL-2 overexpression, is a critical oncogenic mechanism in many hematologic malignancies, notably lymphoid neoplasias. Overexpression of anti-apoptotic BCL-2 proteins is frequent in many malignancies, prompting the development of BCL-2 inhibitors as therapeutic agents.

Methods: In this study, cucurbitacin compounds were screened against BCL-2 using in silico PyRx tool to find strong natural inhibitors for treating hematological malignancies. ADMET-AI web interface was used to analyze ADMET properties of hit compounds. 

Results: Cucurbitacin O, IIb, K, and H were effective BCL-2 inhibitors, with binding energies ranging from
-8.0 to -8.8 kcal/mol, similar to the control compound (-7.9 kcal/mol). These compounds interacted with key amino acid residues in BCL-2. The radial graphs showed that all four compounds had good ADMET characteristics. The compounds have a high probability of being safe for the blood-brain barrier and pose a low risk of hERG channel blockage. Furthermore, they have higher oral bioavailability and adequate water solubility. Their minimal clinical toxicity profiles indicate their potential safety in therapeutic applications.

Conclusion: Cucurbitacin O, IIb, K, and H can be employed as BCL-2 inhibitors to manage hematological malignancies. However, further experimental studies are needed to validate these compounds as BCL-2 inhibitors.

Fouzia Razzaq, Muhammad Bilal bin Majeed, Shagufta Naz, Asad Ali, Afzal Rashid, Haiba Kaulpages 324-330

Read Abstract

 Background: Twinning in sheep is an economically important trait. Of the many genes that can affect litter size in sheep, B4GALNT2 is an important member. Genetic variants found in the B4GALNT2 effect the ovulation and can promote twinning in sheep. Keeping in view the importance of prolificacy in sheep, this research was planned to identify the association of B4GALNT2 gene variants with twining in Lohi sheep.

Methods: A total of 200 blood samples of female sheep (100 each who gave birth to twins and single sheep respectively) were collected from three sheep farms. DNA was extracted and genotyped for B4GALNT2 (rs410464838). For genotyping of SNPs, a PCR-based restriction fragment length polymorphism assay was used. Data were analyzed by using SPSS and R. Hardy-Weinberg equilibrium was evaluated for both groups of sheep. Association of litter size with B4GALNT2 genetic variants was tested through chi square test.

Results: The results of the study showed that genotypes at the B4GALNT2 locus were at Hardy-Weinberg disequilibrium for twin birth. Association analysis revealed a strong association of the AA genotype with twinning. Animals with this genotype were found to be predisposed to having twins. Furthermore, Bayesian analysis reinforced these findings, demonstrating a robust association between the A allele and an increased likelihood of twin births.

Conclusion: Overall, the results of this study indicate that the B4GALNT gene is a good candidate for selection of litter size in sheep. If incorporated as part of a marker assisted selection program, it can result in a sustained expansion of small ruminants to increase mutton production and uplift the socioeconomic condition of small ruminant farmers.

Lamiaa Sobhi Saqer, FathElrahman Mahdi Hassan, Fadel Akram Sharif, pages 340-345

Read Abstract

 Background: α0-thalassemias results from double gene deletions of the α-genes on the same chromosome as in (-α)20.5. In contrast to deletion, α-globin genes triplication (αααanti3.7) is generated by homologous recombination during the process of crossover. This study was conducted to detect (-α)20.5 and ααα anti3.7 mutations in patients with microcytic hypochromic anemia in Gaza Strip-Palestine.

Methods: 200 subjects with microcytic hypochromic anemia with an age range of 18 to 48 years, were recruited from hematological departments of the main hospitals in Gaza Strip. The study subjects were those who underwent premarital β-thalassemia carrier screening, and their results were negative. Iron deficiency was excluded through measurement of serum iron and total iron binding capacity (TIBC). Complete blood count was done automatically. Molecular detection of (-α)20.5 and αααanti3.7 mutations were performed by Multiplex-PCR.

Results: Sixty-six (33%) of the study participants proved to have α-thalassemia. The frequency of (-α)20.5 and αααanti3.7 mutations were: 13.25% and 5.5%, respectively. Four genotypes were detected: -α20.5/αα accounted for 26% (52/200), αααanti3.7/αα for 2.5% (5/200), αααanti3.7/αααanti3.7 for 4% (8/200) and αααanti3.7/-α20.5 for 0.5% (1/200). The comparison of hematological parameters between -α20.5/αα and αααanti3.7 mutation carriers (αααanti3.7/αα and αααanti3.7/αααanti3.7) revealed, though not statistically significant, higher levels in carriers of αααanti3.7 mutation. The   -α20.5/αααanti3.7 genotype was observed in one case.

Conclusion: The rate of -α20.5 and αααanti3.7 in the Palestinian population is high as compared to neighboring countries. Conducting further molecular testing to detect additional α-thalassemia mutations is needed in order to obtain a clearer picture of the genetic nature of this disease.

Detection of Glyphosate in Sheep's Feed and Drinking Water Collected Randomly from Various Agriculture Areas Located in Different Territories of Baghdad Province

Raad jabbar Hammadi, Huda Nsaif Jasim, Mohammed Sadeq Salman, pages 351-356

Read Abstract

 Background: The primary objectives of this study were to employ a quantitative method, specifically High-Performance Liquid Chromatography (HPLC), for the purpose of detecting glyphosate residues (measured in parts per million) in the feed and drinking water consumed by sheep.

Methods: During the period from February 2021 to May 2021, a sample of 30 feed and drinking water samples from sheep was collected in a random manner. These samples consisted of 15 feed samples and 15 drinking water samples. The collection was conducted in various agricultural areas situated in different territories within the province of Baghdad.

Results: The HPLC residues study showed that 12 and 7 samples, respectively, had glyphosate residues in sheep feed and drinking water. Of the 15 feed samples analyzed, 12 were positive for glyphosate residues: 5 alfalfa, 4 barley, and 3 clover samples. Alfalfa, barley, and clover had the greatest glyphosate residues (140.5–145.5, 120.7–139.5, and 119.5–128.2 ppm), respectively. HPLC analysis showed that all forage samples—alfalfa, barley, and clover—exceeded the Maximum Residue Levels (MRLs) (0.05, 20, and 0.05), violating the EFSA's 2019 recommendation for glyphosate (ppm) in sheep feed. Alfalfa showed the most significant violation, with residue levels over 2,800-fold the Maximum Residue Level (MRL), followed by clover (over 2,400-fold) and barley (6.5-fold). Sheep's Water (Barn, Field, and Drained) samples (5 of each) were positive for glyphosate residues (2, 3, and 2), with the highest ranges in Field (104.1–106.3), Barn (83.7–85.5), and Drained (0.3–0.5). HPLC analysis showed that all water samples except Drained water (Barn and Field) above the Maximum Contamination Level (MCL) (0.7), violated the EPA's glyphosate (ppm) recommendation. HPLC analysis showed that glyphosate levels in Barn and Field water were dramatically above the MCL, exceeding the EPA's recommendation by over 120-fold and 150-fold, respectively.

Conclusion: The utilization of glyphosate has exhibited a progressive rise over the course of time, thereby eliciting apprehensions regarding the potential toxicity of this herbicide as well as its plausible impact on human health. Glyphosate residues have the potential to be transmitted to humans or animals via water, feed, and food that has been contaminated.

Preliminary Findings on the Movement and Habitat Preferences of Moza, a Rescued Green Sea Turtle (Chelonia mydas) in Fujairah, UAE, through Satellite Tagging

Maryam Alhefeiti, Fawaghy Alhashmi, Sabhah Alhmoudi, Fouad Lamghari, Shaher Bano Mirza, pages 357-361

Read Abstract

 Background: On May 14, 2022, Moza, a sub-adult green turtle (Chelonia mydas), was discovered injured on the eastern coast of the United Arab Emirates, in the Gulf of Oman. Later, it got rehabilitated and released back to sea with tracker and given the title “Moza”. Given the increasing concerns about marine animal behavior and habitat preferences, this study sought to track and analyze Moza's movements.

Methods: The tracking of turtles was conducted using SPOT-5 back-mount tags supplied by Wildlife Computers, a company based in Seattle, USA. These tags establish communication with the Argos satellite system (http://www.argos-system.org) anytime they rise above the water, and a satellite is within their reach. To preserve battery life and prolong the period of tracking, the tags were set to restrict the number of broadcasts to 250 per day, which were scheduled exclusively during daylight hours (06:00–18:00). The SPOT-5 tags not only communicated location data for the Argos system but also provided temperature information. The investigation was conducted from June 16 to July 31, 2022, along the shoreline near Deira Island, Palm Island, and Dubai World Island. Moza was initially released from Palm Island on June 16, 2022.

Results: The satellite tracking revealed that Moza was located at Dubai World Islands on June 18, 2022, and by June 19, 2022, she had moved to Deira Islands, where she remained for the rest of the study period. Over a tracking period of 45 days (1077.86 hours), Moza traveled a total of 86.3 kilometers in a southwesterly direction from the starting point.

Conclusion: The findings suggest that Moza ceased long-distance movement and remained in the Deira Islands area, likely due to the presence of a suitable habitat. However, ongoing tracking studies with other rehabilitated turtles may provide further insights into habitat preferences and movement patterns.

In Silico Study of Innovative Compounds Targeting Protein (Survivin): Understandings into Cancer Therapeutics

Abdullah Hamadi, Hyfa Alzahrani, Fawzyah Albaldi, Sallwa M Alshehre, Ali Mahzari, pages 362-370

Read Abstract

 Background: Survivin, also known as Baculoviral Inhibitor of Apoptosis Repeat Containing 5 (BIRC5), is a key protein involved in cell division and the inhibition of apoptosis, making it an essential component of eukaryotic cell biology. Survivin is highly expressed across all human tumor lines and is significant in cancer due to its dual function in promoting cell proliferation and inhibiting apoptosis. Programmed cell death (PCD) is critical for mammalian development and disease regulation. The dysregulation of apoptosis leads to uncontrolled cell proliferation, which contributes to tumor progression and metastasis. Survivin interacts with caspases, predominantly inhibiting Caspase-3 and Caspase-7, thereby playing a key role in dysregulating apoptosis. Given its preferential expression in tumor cells and its decisive role in carcinogenesis and chemoresistance, Survivin emerges as an attractive target for cancer treatment.

Methods: Compounds from the PubChem database were screened using molecular docking. Lead candidates were then evaluated for drug-likeness and ADMET properties, and the stability of the top compound-protein complex was analyzed using molecular dynamics simulations.

Results: The current study highlights the therapeutic potential of novel compounds designed to inhibit Survivin in cancer therapy. This probability is illuminated through the use of innovative techniques such as computer-generated (virtual) screening and molecular docking. The lead compounds have also been filtered for their drug-likeness and ADMET potential.

Conclusion: The stability of the designated compounds has been investigated in-depth through MD simulations. The results from this study suggest that the compound CID:155104111 (1-[2-(difluoromethoxy)ethyl]-2-methyl-3-(pyrazin-2-ylmethyl)benzo[f]benzimidazol-3-ium-4,9-dione) is a potential lead candidate for targeting the Survivin protein, showing promise when compared to the standard inhibitor, YM155.

Read Abstract

  Background: Alzheimer's disease (AD) is a neurological ailment that causes progressive memory loss as neurons die. Beta-secretase 1 (BACE1) is a key enzyme in the production of amyloid beta, which is a characteristic of Alzheimer's disease. Developing new BACE1 inhibitors with no cytotoxicity is a promising method to treat AD.

Methods: The goal of this study was to find new BACE1 inhibitors by screening natural compounds in the ZINC database against the BACE1 active site. The compounds were screened against BACE1 using the PyRx 0.8 program. The SwissADME web server was used to determine the ADMET properties of hit compounds.

Results: The hit compounds ZINC3875408, ZINC4098603, ZINC95561079, ZINC299817515, and ZINC67903362 exhibited higher binding affinities to BACE1 than the control compound AZD3293. The Asp32, Lys224, Tyr198, Thr329, Ile226, Val332, Arg128, Tyr71, Phe108, Lys107, Gly74, Gly13, Gly11, Gln12, Ile110, Trp115, Leu30, and Gly230 were the important binding residues of BACE1 protein with these compounds as well as the control compound. These compounds also have good drug-like qualities.

Conclusion: The compounds ZINC3875408, ZINC4098603, ZINC95561079, ZINC299817515, and ZINC67903362 can be used as BACE1 inhibitors to manage AD. However, experimental validation is needed to optimize these compounds as BACE1 inhibitors.

Target-based Virtual Screening of Natural Compounds as Promising Anti-Parkinson’s Agents

Israa J. Hakeem, pages 389-392

Read Abstract

  Background: Parkinson's disease (PD), the second most common neurodegenerative disease among the elderly, is caused by the death of dopaminergic neurons, resulting in dopamine depletion. Monoamine oxidase B (MAO-B) is an important enzyme in PD because it degrades dopamine. Dopamine levels can be elevated by inhibiting MAO-B, especially in the early stages of the disease.

Methods: This study involves virtual screening (docking) of ZINC database natural compounds (N = 200) against MAO-B, followed by ADME and drug-likeness analysis of the top hits.

Results: ZINC899884, ZINC4098705, ZINC14764165, and ZINC18847036 compounds exhibited strong binding to MAO-B and interacted with key MAO-B residues. The Cys172, Ile198, Phe168, Ile199, Leu171, Gln206, Gly58, Tyr326, Leu328, Phe343, Tyr398, Ser59, Tyr60, Gly434, and Tyr435 residues of MAO-B were important in binding with these compounds. In addition, these compounds, like the control Rasagiline, interact with MAO-B via several common residues. Furthermore, ADME and drug-like prediction resulted in promising results, indicating that these compounds have a high gastrointestinal absorption property.

Conclusion: ZINC899884, ZINC4098705, ZINC14764165, and ZINC18847036 can be used as MAO-B inhibitors for PD. However, experimental validation is required to optimize them as MAO-B inhibitors.

Evaluation of the General Population’s Knowledge, Attitudes, and Practices about Herpes Zoster Vaccination in the Northern Border and Al-Jouf Region of Saudi Arabia

Ahmed Subeh Alshrari, pages 393-398

Read Abstract

 Background: The knowledge, attitude, and practice (KAP) of the general population concerning HZ and its vaccine are not well established in many regions of Saudi Arabia, including the Northern Border Region of Saudi Arabia (NBRSA) and Al-Jouf Region of Saudi Arabia (AJRSA). Accordingly, this study intended to evaluate the KAP of the individuals residing in the NBRSA and AJRSA.

Methods: The data of this cross-sectional investigation was collected employing an online survey questionnaire through Google Forms. The questionnaire comprised questions related to demography and KAP of the general population of NBRSA and AJRSA about HZ and HZ vaccination. The data was collected and the significance of the results was analyzed by utilizing SPSS version 21 software (p < 0.05 = significant result).

Results: The study comprised 483 participants from the NBRSA (50.72%) and AJRSA (49.27%). Most of the participants were from 40-45 (69.56%) years of age; females (60.86%); Saudi nationals (94.20%); university graduates (52.17%); belonged to the non-health sector (59.42%); and were not suffering from any chronic disease (78.26%). A majority of the participants (> 50%) had poor awareness about HZ and HZ vaccine. An appreciable number of participants (68.11%) were eager to learn more about HZ. The main source of information for HZ was the internet (46.37%) for most of the individuals.

Conclusion: There is a considerable information gap as well as a low HZ vaccination rate among the people of NBRSA and AJRSA warranting initiating educational and awareness programs in these regions.

Possible Approaches for the Origin of Life in Hot Mineral Water in Primary Hydrosphere

Ignat Ivanov Ignatov, Teodora Petrova Popova, pages 399-412

Read Abstract

 Background: Protostructure emerges under corona discharge as ions and water molecules self-organize into stable formation. With 45.6 % density relative to living cells, this structure represents a primitive stage of biochemical evolution. Their formation follows Prigogine’s principle of entropy reduction, illustrating the potential role of early Earth’s reducing atmosphere and mineral surfaces in catalyzing the origin of complex biochemical systems.

Methods: Using hot mineral water from Rupite, Bulgaria, we conducted experiments involving corona electric discharge (1–30 kHz, 12 kV) to simulate prebiotic conditions. Fourier Transform Infrared (FT-IR) spectroscopy was employed to analyze the water's inorganic and organic composition. Additionally, we assessed the oxidation-reduction potential (ORP) and measured changes in physicochemical parameters under controlled conditions.

Results: The protostructure was created in laboratory conditions in hot mineral water under corona electric discharge. Self-organization estimation using Prigogine’s principle marks an early stage of biochemical evolution, emphasizing the role of the primordial atmosphere and hydrosphere in life's origin. The structure density was 45.6% of that of living cells. We quantitatively estimated the results of Miller’s and Wilson’s experiments. The biochemical reactions were described with the compounds as methane, ammonia, etc.

Conclusion: The findings support the hypothesis that hot mineral water in the primary hydrosphere, enriched with ions, exposed to electric discharge in the primary atmosphere, and with contact medium with the hydrosphere, providing optimal conditions for synthesizing organic compounds and forming protostructures. These results reinforce the concept of geothermal systems of life and highlight the significance of mineral water’s physicochemical properties in fostering prebiotic chemistry.

Syed Raziuddin Quadri, Wesam Nofal, Muhannad Alruwaili, pages  413-417

Read Abstract

 Background: Members of the genera Larkinella and Tellurirhabdus are Gram-negative, aerobic, and consist of menaquinone (MK)-7 as their main isoprenoid quinone. Recent analysis suggests that both genera share similar characteristics. The taxonomic position of the genera Larkinella and Tellurirhabdus has been evaluated using genomic analysis.

Methods: The quality of the genomic sequences of Larkinella and Tellurirhabdus was assessed after they were downloaded from NCBI (https://www.ncbi.nlm.nih.gov/). Average nucleotide identity (ANI) and average amino acid identity (AAI) data was used for evaluating their genomic relatedness.

Results: The AAI values between Larkinella and Tellurirhabdus were above the threshold value of genus delineation (>60–65 %) indicating that they are members of the same genus. The ANI values among Larkinella and Tellurirhabdus species were below 95-96% indicating they were different species.

Conclusion: We propose transferring Tellurirhabdus bombi to the genus Larkinella as Larkinella bombi comb. nov. and Tellurirhabdus rosea to the genus Larkinella as Larkinella roseola nom. nov. based on our research findings.

Mahmoud Mansour, Tariq Aldebasi, Abeer Alzubaidi, Abdulsalam Alanazi, Abdulaziz Alarifi, Fahad Almutairi, Mohammed Alfaifi, Norah Aldeghaither, Yousef Al-Rajhi, Saad Alnofaie, pages  418-424

Read Abstract

 Background: The most important advancement in the treatment of glomerulonephritis is the application of rituximab (MabThera®), for several decades. Rituximab biosimilar (Truxima®) was approved for the same indications offering significant cost savings. This study aimed to compare the safety and efficacy of rituximab biosimilar (Truxima) with the reference rituximab product (MabThera) in the treatment of glomerulonephritis, using both laboratory and clinical parameters to assess their similarity.

Methods: We examined the clinical results retrospectively and collected the data of the laboratory parameters from 65 patients suffering from glomerulonephritis treated with either Truxima or MabThera, for disease induction and maintenance of remission, at the King Abdulaziz Medical Centre, Al-Riyadh between 2019 and 2023.

Result: The present study shows no significant difference in rates of remission and relapse between patients receiving Truxima or MabThera treatment.  There were no significant differences in the patients’ complete renal recovery at 6 months between the two groups, P = .692. Additionally, no remarkable differences between both medications in the patients' time to relapse. A comparison of mean clinical data for serum creatinine, cholesterol and blood indices at baseline, 6 months and 12 months of the patients in Truxima® and MabThera® groups revealed that patients who received MabThera® had a significantly higher WBC count at 6th month, P = .030 only.

Conclusion: The current study shows that (Truxima) is just as safe and effective as its original product, (MabThera). Therefore, Truxima is a more affordable and safer alternative that potentially increases rituximab accessibility to patients.

Diagnosis of Human Cases of Echinococcosis in Iraq (2021-2023): An Analysis of Gender, Age, and Affected Organs

A.O. Humide, Thaer Abdulqader Salih, Ezeddin A. Albayyar, pages  435-439

Read Abstract

 Background: Cystic echinococcosis is a chronic zoonotic disease in humans caused by infection with canine tapeworm larvae. The species of echinococcus has a two-host life cycle. Cystic echinococcosis (CE) is classified as an emergent condition since cysts can develop to a size of 5 to 10 cm during the first year of infection and continue to grow for years or even decades before the illness is spotted affecting several organs.

Methods: 52 patients who were admitted to Al-Ramadi Teaching Hospital, Fallujah Teaching Hospital, and other nearby private hospitals between 2021/7/8 and 2023/8/21 are the subject of this article. Cysts from various organs in patients of both sexes and of varied ages were removed, some of which included the cysts of echinococcosis infected persons.

Results: According to our research, the liver was the organ that had hydatid cyst infections most commonly, with a damage frequency of 46.2%. According to the statistics, the prevalence of infection in the other organs, which were listed after the liver, was 25.0% (spleen, bone, and bile duct) and 23.1% cases were of lung infection. It was found that the likelihood of liver and lung injuries happening concurrently was the lowest (5.8%) of all the infections.

Conclusion: The study shows hydatid disease primarily affects the liver and lungs, with females and the 20–40 age group being the most impacted. Infection rates increased from 2021 to 2023. Surgery remains the main treatment, though medical therapies have varied success, especially for lung cases. Gender, age, and cyst location significantly influence disease outcomes.

Analyzing the Possible Impact of Herpes Simplex Virus-1 in Relation to Interleukin-6 Levels in Patients with Oral Squamous Cell Carcinoma

Marwa Mohammed Ali Jassim, Shireen Ahmed Dzayee, Majid Mohammed Mahmood, pages  440-444

Read Abstract

  Background: Oral squamous cell carcinoma (OSCC) is the most common malignant tumor of the oral cavity, accounting for more than 90% of all cases. Oral herpes is caused by herpes simplex virus type 1 (HSV-1), a common, benign virus that affects the skin and mucous membranes of individuals with weakened immune systems, causing ulcers. There are several cellular processes that rely on the pleiotropic cytokine interleukin-6 (IL-6), including migration, invasion, differentiation, proliferation, and survival. By modifying tumor angiogenesis and tumor lymphangiogenesis, IL-6 controls tumor growth and its effects on tumor cells.

Methods: The study involved 60 patients divided into two groups: those with and those without oral cancer. The blood was drawn and examined for HSV-1 Immunoglobulin G levels using the Herpe Select-1 ELISA kit. A sandwich ELISA was also employed to study IL-6 levels.

Result: HSV-1 incidence in these oral squamous cell carcinoma grade groups increased significantly. This research found that the OSCC group had somewhat greater IL-6 levels than the control groups.

Conclusion: HSV-1 is not carcinogenic in its own right; however, it is linked to an increased risk of oral squamous cell carcinoma. In addition, the present study discovered that the pro-inflammatory cytokine IL-6 was present in greater quantities in patients' blood than in controls. Interleukin-6 was identified as a potentially hazardous factor in the development of oral cancer and has the potential to function as a valuable biomarker for the assessment of OSCC severity.

Read Abstract

  Background: The work described herein investigates the properties of the enzyme isocitrate lyase, which was purified from corn plants using advanced techniques such as sulfate precipitation and ion exchange chromatography. The results indicated the presence of two forms of the enzyme, ICL1 and ICL2, which differed in their molecular weights and enzymatic activities. The optimum pH for ICL1 was found to be 7.5, while for ICL2, it was 6. Additionally, the effects of glycine and glycolate on the enzyme's activity were studied, revealing elevated activities at the optimal concentrations of these substances.

Methods: The isocitrate lyase enzyme was purified from corn plants using ion exchange chromatography and sulfate precipitation techniques. Enzyme activity was assessed using spectrophotometric methods, and the molecular weight was determined through gel chromatography. Studies were conducted to investigate the influence of pH, glycine, and glycolate on enzyme activity.

Results: Two isoforms of isocitrate lyase, ICL1 and ICL2, were purified, exhibiting molecular masses of 164 kDa and 208 kDa, respectively. ICL1 demonstrated optimum activity at pH 7.5, while ICL2 exhibited optimum activity at pH 6. In this study, specific concentrations of glycine and glycolate were found to enhance the enzymatic activities of both isoforms.

Conclusion: This research provides significant insights into the characteristics of the isocitrate lyase enzyme in corn plants. The data indicate the presence of distinct enzyme forms with specific interactions in varying environmental conditions, which may be applicable in agricultural practices to increase crop yield and improve the metabolic turnover of organic acids.

Isolation and Screening of the Heavy Metals, Antibiotics Resistant and Acidophilic Profile of Bacterial strains from Lead Acid Batteries Repairing and Recycling Units

Sulaiman Faisal, Gulzar Ahmad, Zia Ur Rahman, Muhammad Taimur Asad, Muhammad Ijaz, Adil Ahmad, Sidra Ahmad, Saqib Rauf, Neelum Iqbal, Sajjad Ullah, pages 451-459

Read Abstract

  Background: Heavy metal contamination from unregulated waste disposal poses serious risks to ecosystems, soil, water, and human health. Lead acid battery recycling sites are major sources of such pollution. This study aimed to isolate and characterize bacterial strains with potential for bioremediation from lead acid battery workshops in Shoba Bazaar, Peshawar.

Methods: Water samples were collected from contaminated sites and cultured in both nutrient agar and LB media. After incubation, 30 bacterial isolates were screened for tolerance to cadmium, lead, zinc, and chromium (50–300 mM), as well as resistance to commonly used antibiotics (ampicillin, amoxicillin, azithromycin, cefixime, and kanamycin). The most tolerant strains, designated LRB1, LRB2, and LRB3, were further analyzed for acid and temperature resistance. Morphological and molecular characterization included Gram staining, microscopic analysis, plasmid isolation and genomic DNA extraction.

Results: Isolates LRB1, LRB2, and LRB3 demonstrated high lead tolerance of 270 mM, 300 mM, and 270 mM, respectively. All three strains exhibited resistance to multiple antibiotics like ampicillin (10μg), amoxicillin (30μg), azithromycin (15μg), cefixime (5μg) and kanamycin (30μg), and LRB3 showed growth across a broad pH range (2–8). Plasmid DNA was successfully isolated, indicating potential plasmid-mediated resistance. Gram staining revealed that the isolates were Gram-positive bacilli and cocci. Furthermore, genomic DNA extraction and 16S rDNA PCR with universal primers were used for detection and identification of the bacterial isolates.

Conclusion: The isolated bacterial strains demonstrated remarkable tolerance to heavy metals, acids, and antibiotics, suggesting their potential role in the bioremediation of contaminated environments. Further molecular studies are required to elucidate the mechanisms underlying their resistance and to evaluate their suitability for biotechnological applications.

Optimizing Blood-Stage Vaccines: Essential Tools in Malaria Eradication Strategies

 Musa Ahmad Aminu, Aneeq Ur Rehman, Atif Amin Baig, Ahmed M. Salman, Ahmad Syibli Othman, pages 425-434 

Read Abstract

This review examines Diabetic Peripheral Neuropathy (DPN), a significant complication of diabetes affecting nearly half of diabetic patients. DPN is crucial to understand due to its high prevalence and profound impact on patients’ quality of life, causing pain, sensory loss, motor dysfunction, and heightened risks of foot ulcers and amputations. As a leading cause of disability, grasping DPN’s pathophysiology, early diagnosis, and treatment options are essential for alleviating its burden. Key facets of DPN include its complex pathophysiology stemming from chronic hyperglycemia, oxidative stress, inflammation, and vascular problems that damage nerves. The review highlights the rising rates of diabetes and DPN in regions like Saudi Arabia, noting that factors such as poor glycemic control, prolonged diabetes duration, and comorbidities like hypertension significantly contribute to DPN progression. Diagnostic challenges are also addressed; traditional nerve conduction studies are gold standards yet limited in detecting early-stage neuropathy, especially small-fiber damage. Emerging methods, like skin biopsy and corneal confocal microscopy, show promise for earlier detection. Treatment mainly focuses on glycemic control and pain management without reversing nerve damage. Innovative therapies targeting DPN mechanisms include antioxidant treatments, anti-inflammatory agents, and phytomedicine, which utilizes bioactive compounds for their neuroprotective effects. The review concludes by stressing the need for ongoing research into DPN's molecular mechanisms and the development of personalized medicine approaches, which could significantly enhance patient outcomes.
