Abstract
The multicomponent etiology, complex clinical implications, dose-based side effect and degree of pain mitigation associated with the current pharmacological therapy is incapable in complete resolution of chronic neuropathic pain patients which necessitates the perpetual requirement of novel medication therapy. Therefore, this study explored the ameliorative aptitude of two novel methanimine imitative like (E)-N-(4-nitrobenzylidene)-4-chloro-2-iodobenzamine (KB 09) and (E)-N-(4-methylbenzylidene)-4-chloro-2-iodobenzamine (KB 10) in chronic constriction injury (CCI) of sciatic nerve induced neuropathic pain in rat model. Standard behavioral tests like dynamic and static allodynia, cold, thermal and mechanical hyperalgesia along with rotarod activity were performed at various experimental days like 0, 3, 7, 14 and 21. Enzyme linked immunosorbent assay (ELISA) on spinal tissue and antioxidant assays on sciatic nerve were executed accompanied by molecular docking and simulation studies. Prolonged ligation of sciatic nerve expressively induced hyperalgesia as well as allodynia in rats. KB 09 and KB 10 substantially attenuated the CCI elicited hyperalgesia and allodynia. They significantly reduced the biomarkers of pain and inflammation like Interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) in ELISA and while enhanced the GSH, SOD and CAT and diminished the MDA levels during antioxidant assays. KB 09 displayed -9.62 kcal/mol with TNF-α and -7.68 kcal/mol binding energy with IL-6 whereas KB 10 exhibited binding energy of -8.20 kcal/mol with IL-6 while -11.68 kcal/mol with TNF-α and hence both trial compounds ensured stable interaction with IL-6 and TNF-α during computational analysis. The results advocated that both methanimine derivatives might be novel candidates for attenuation of CCI-induced neuropathic pain prospects via anti-nociceptive, anti-inflammatory and antioxidant mechanisms.

Abstract
The Plasmodium is responsible for malaria which poses a major health threat, globally. This study is based on the estimation of the relative abundance of mosquitoes, and finding out the correlations of meteorological parameters (temperature, humidity and rainfall) with the abundance of mosquitoes. In addition, this study also focused on the use of nested PCR (species-specific nucleotide sequences of 18S rRNA genes) to explore the Plasmodium spp. in female Anopheles. In the current study, the percentage relative abundance of Culex mosquitoes was 57.65% and Anopheles 42.34% among the study areas. In addition, the highest number of mosquitoes was found in March in district Mandi Bahauddin at 21 °C (Tmax = 27, Tmin = 15) average temperature, 69% average relative humidity and 131 mm rainfall, and these climatic factors were found to affect the abundance of the mosquitoes, directly or indirectly. Molecular analysis showed that overall, 41.3% of the female Anopheles pools were positive for genus Plasmodium. Among species, the prevalence of Plasmodium (P.) vivax (78.1%) was significantly higher than P. falciparum (21.9%). This study will be helpful in the estimation of future risk of mosquito-borne diseases along with population dynamic of mosquitoes to enhance the effectiveness of vector surveillance and control programs.

Abstract
Endometritis reduces reproductive effectiveness and leads to significant financial losses in the dairy sector. Luteolin is a natural phyto-flavonoid compound with many biological activities. However, the therapeutic effect of Luteolin against lipopolysaccharides (LPS)-induced endometritis has not yet been explored. A total of eighty female Kunming mice were randomly assigned into four treatment groups (n = 20). Following a successful initiation of the endometritis model by LPS, Luteolin was intraperitoneally administered three times, at six-hour intervals between each injection in the Luteolin groups. The histopathological findings revealed that Luteolin significantly alleviated uterine injury induced by LPS. Moreover, Luteolin suppressed the synthesis of pro-inflammatory mediators [interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α] while promoting the synthesis of an anti-inflammatory mediator (IL-10) altered by LPS. Furthermore, Luteolin significantly mitigated the LPS-induced oxidative stress by scavenging malondialdehyde (MDA) and reactive oxygen species (ROS), accumulation and boosting the capacity of antioxidant enzyme activities such as superoxide dismutase 1 (SOD1), catalase (CAT), and glutathione peroxidase 1 (Gpx1) in the uterine tissue of mice. Additionally, injection of Luteolin markedly increased the expression of Toll-like receptors (TLR) 4 both at mRNA and protein levels under LPS stimulation. Western blotting and ELISA findings demonstrated that Luteolin suppressed the activation of the NF-κB pathway in response to LPS exposure in the uterine tissue of mice. Notably, Luteolin enhanced the anti-oxidant defense system by activating the Nrf2 signaling pathway under LPS exposure in the uterine tissue of mice. Conclusively, our findings demonstrated that Luteolin effectively alleviated LPS-induced endometritis via modulation of TLR4-associated Nrf2 and NF-κB signaling pathways.

Abstract
Apple is an important fruit crop that is always in demand due to its commercial and nutraceutical value. Also, the requirement for quality planting material for this fruit crop for new plantations is increasing continuously. In-vitro propagation is an alternative approach, which may help to produce genetically identical high grade planting material. In this study, for the first time, an efficient and reproducible propagation protocol has been established for apple root stock MM 104 via axillary bud. Culturing axillary buds on Murashige and Skoog apple rootstock (MM 104) resulted in better in-vitro propagation. (MS) basal medium supplemented with 3.0% (w/v) sucrose and 0.8% (w/v) agar. The axillary buds were established in MS basal medium with BA (5.0 µM), NAA (1.0 µM) and further used to establish invitro propagation protocol. Plant Growth Regulators (PGRs), BA (1.0 µM) in combination with NAA (1.0 µM) was found most efficient for shoot multiplication (100%) and produced 9.8 shoots/explants with an average shoot length of (2.4 ± cm). All the shoots produced roots in 0.1 µM IBA with a 5-day dark period. Acclimatization of in-vitro raised plantlets was obtained with vermiculite: perlite: sand: soil (2:2:1:1) resulting in 76% survival under field conditions. The study showed that the use of axillary bud is efficient for multiple-shoot production of apple rootstock (MM 104). This is the first comprehensive report on in-vitro growth of apple root stock MM 104 with an assessment of genetic stability using DNA fingerprinting profiles based on Inter Simple Sequence Repeats (ISSR) and Start Codon Targeted (SCoT). The genetic stability of in-vitro-produced plants, as determined by SCoT and ISSR primers, demonstrated genetic closeness to the mother plant.

Abstract
Nanomaterials containing tungsten (TNMs), characterized by diverse nanostructures had been extensively used in biomedical sector. Despite numerous reports focusing on TNM applications in specific biomedical areas, there is a noticeable absence of comprehensive studies that focused on detailed characterization of nanomaterials along with their biological applications. The present work described the structural, morphological, and antimicrobial properties of tungsten oxide (WO3) nanoparticles coated by antibiotics (nanobiotics), and their application on single and mixed bacterial culture. The nanobiotics included in this study were WO3 coated with ampicillin (W+A), WO3 coated with penicillin (P+W), and WO3 coated with ciprofloxacin (C+W). Techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray spectroscopy (EDX), Fourier transforms infrared spectroscopy (FTIR), Rrman spectroscopy, and UV-visible spectroscopy were used to characterize synthesized nanoparticles. The minimum inhibitory concentration of C+W nanobiotic against S. aureus, E. coli, and mixed culture (S. aureus +E. coli) was lower than that of P+W and A+W. The impact of incubation period showed significant differences for each of nanobiotic against S. aureus, E. coli, and mixed culture. However, there were also non-significant differences among incubation periods for antibacterial activity of nanobiotics. It was pertinent to note that percentage variation in susceptibility of S. aureus with respect to mixed culture remained higher as compared to E. coli, indicating it stronger candidate imposing resistance. This paper thus suggested the strategy of coating of antibiotics with with WO3 nanoparticles as an ideal combination for resistance modulation against single and mixed culture bacteria.

Abstract
High-altitude environments present formidable challenges for survival and reproduction, with organisms facing limited oxygen availability and scarce nutrient resources. The yak (Bos grunniens), indigenous to the Tibetan Plateau, has notably adapted to these extreme conditions. This study delves into the genomic basis of the yak's adaptation, focusing on the positive selection acting on genes involved in nutrient assimilation pathways. Employing techniques in comparative genomics and molecular evolutionary analyses, we selected genes in the yak that show signs of positive selection associated with nutrient metabolism, absorption, and transport. Our findings reveal specific genetic adaptations related to nutrient metabolism in harsh climatic conditions. Notably, genes involved in energy metabolism, oxygen transport, and thermoregulation exhibited signs of positive selection, suggesting their crucial role in the yak's successful colonization of high-altitude regions. The study also sheds light on the yak's immune system adaptations, emphasizing genes involved in response to various stresses prevalent at elevated altitudes. Insights into the yak's genomic makeup provide valuable information for understanding the broader implications of high-altitude adaptations in mammalian evolution. They may contribute to efforts in enhancing livestock resilience to environmental challenges.

Abstract
COVID-19 appeared as a highly contagious disease after its outbreak in December 2019 by the virus, named SARS-CoV-2. The threat, which originated in Wuhan, China, swiftly became an international emergency. Among different genomic products, spike protein of virus plays a crucial role in the initiation of the infection by binding to the human lung cells, therefore, SARS-CoV-2's spike protein is a promising therapeutic target. Using a combination of a structure-based virtual screening and biochemical assay, this study seeks possible therapeutic candidates that specifically target the viral spike protein. A database of ~ 850 naturally derived compounds was screened against SARS-CoV-2 spike protein to find natural inhibitors. Using virtual screening and inhibitory experiments, we identified acetyl 11-keto-boswellic acid (AKBA) as a promising molecule for spike protein, which encouraged us to scan the rest of AKBA derivatives in our in-house database via 2D-similarity searching. Later 19 compounds with > 85% similarity with AKBA were selected and docked with receptor binding domain (RBD) of spike protein. Those hits declared significant interactions at the RBD interface, best possess and excellent drug-likeness and pharmacokinetics properties with high gastrointestinal absorption (GIA) without toxicity and allergenicity. Our in-silico observations were eventually validated by in vitro bioassay, interestingly, 10 compounds (A3, A4, C3, C6A, C6B, C6C, C6E, C6H, C6I, and C6J) displayed significant inhibitory ability with good percent inhibition (range: > 72-90). The compounds C3 (90.00%), C6E (91.00%), C6C (87.20%), and C6D (86.23%) demonstrated excellent anti-SARS CoV-2 spike protein activities. The docking interaction of high percent inhibition of inhibitor compounds C3 and C6E was confirmed by MD Simulation. In the molecular dynamics simulation, we observed the stable dynamics of spike protein inhibitor complexes and the influence of inhibitor binding on the protein's conformational arrangements. The binding free energy ΔGTOTAL of C3 (-38.0 ± 0.08 kcal/mol) and C6E (-41.98 ± 0.08 kcal/mol) respectively indicate a strong binding affinity to Spike protein active pocket. These findings demonstrate that these molecules particularly inhibit the function of spike protein and, therefore have the potential to be evaluated as drug candidates against SARS-CoV-2.

Abstract
Polycystic ovary syndrome (PCOS) is a common hormonal disorder that affects women of reproductive age and is characterized by multiple ovarian cysts, irregular menstrual cycles, and excessive androgen hormone production. The present study aimed to investigate the therapeutic efficacy of melatonin in alleviating PCOS-induced alterations in female Wistar rats. PCOS was induced in female albino rats by administering letrozole at a dose of 1 mg/kg for 21 days. A total of 24 rats were randomly selected and divided into four groups: group I (normal control), group II (melatonin treatment), group III (letrozole treatment), and group IV (melatonin therapy for PCOS rats). Physical parameters (body and uterus weight), hormone profile (LH and FSH), and steroidogenic enzyme activities and an oral glucose test were assessed using standard methods. Histological analysis was performed using hematoxylin and eosin staining. The results demonstrated that exogenous melatonin administration significantly improved PCOS symptoms in rats, including reduced body weight gain, changes in organ weight/body weight index, blood glucose level, percentage diestrus phase, testosterone, estradiol, progesterone, and LH/FSH ratio, as well as 3β-HSD and 17β-HSD enzyme activity. Histopathological findings revealed well-developed follicles, decreased cystic follicles, and increased antral follicles, Graafian follicles, and corpus luteum in PCOS rats treated with melatonin. These positive outcomes suggest that exogenous melatonin may hold promise as a valuable remedy for PCOS conditions in female rats. Further research is warranted to fully elucidate the underlying mechanisms and potential clinical applications of melatonin in the context of PCOS.

Abstract
This study investigated the dynamics in pyrethriod resistance and the presence/frequencies of L1014F knockdown resistance mutant allelles in Culex quinquefasciatus vector populations from Uruan Local Government Area of AkwaIbom State, Southern Nigeria between the months of March and November, 2021. Uruan LGA is among the endemic LGAs for lymphatic filariasis in AkwaIbomState. Female Anopheles mosquitoes from Eman Uruan, Ituk Mbang and Idu Uruan were exposed to permethrin, deltamethrin and alphacypermethrin in CDC insecticide coated bottles for susceptibility bioassay following standard protocols. The mosquitoes were obtained as aquatic forms from the study sites and reared under laboratory conditions to adults. The adult mosquitoes were used for this study. All the mosquitoes used for the insecticide susceptibility bioassay were morphologically identified. Standard Polymerase chain reaction (PCR) was used for authenticating the Culex quinquefasciatus species. A portion of the vgsc (917 bp) gene spanning the entire intron and the exon containing the L1014F mutation associated with knockdown resistance (kdr) in the vectorswere amplified using Allele-SPECIFIC POLYMERASE CHAIN REACTION (AS-PCR) in order to detect target site insensitivity in the vectors from the study sites. Results obtained revealed that vectors from all the study sites were resistant to permethrin insecticide (mortality rate: 18-23%). Suspected resistance (mortality rate: 90-93%) to deltamethrin and low resistance (mortality rate: 82-85%) to alphacypermethrin insecticides were detected. knockdown was more rapid with deltamethrin and alphacypermethrin than with permethrin across the study sites considering their KDT50 and KDT95. The frequency of the resistant phenotypes ranged from 35.14 to 55.3% across the study sites with a net of 45.1% resistant phenotype recorded in this study. The 1014F allelic frequency calculated from Hardy-Weinberg principle for vector populations across the study sites ranged from 0.500 (50.00%) to 0.7763 (77.63%). All populations witnessed significant (p < 0.05) deviations from Hardy-Weinberg equilibrium in the distribution of these alleles. The findings of this study show that there is a tendency to record an entire population of resistant vectors in this study area over time due to natural selection. The public health implication of these findings is that the use of pyrethroid based aerosols, coils, sprays, LLITNs and others for the purpose of controlling vectors of lymphatic filariasis and other diseases may be effort in futility.

Abstract
Despite its clinical value, cisplatin (CISP) is complicated by marked hepatotoxicity via inducing oxidative stress, inflammatory, and apoptotic pathways. This study aims to explore the protective impact of azilsartan (AZIL), an antihypertensive drug, in addition to adipose tissue-derived mesenchymal stem cells (AD-MSCs) on CISP-induced hepatotoxicity. After characterization and labeling of AD-MSCs by PKH26 dye, 54 Wistar male albino rats were randomly divided into nine groups: I (CONT), II (AZIL.H), III (CISP), IV (CISP + AZIL.L), V (CISP + AZIL.H), VI (CISP + AD-MSCs), VII (CISP + AZIL.L + AD-MSCs), VIII (CISP + AZIL.H + AD-MSCs), and IX (CISP + VITA C). Serum alanine aminotransferase (ALT), alanine aminotransferase (AST), and albumin levels were determined. Assessment of reactive oxygen species, malondialdehyde, and glutathione contents, and superoxide dismutase activity and histopathological evaluations were done on hepatic tissue. Quantitative real-time PCR was utilized to estimate the expression of TNF-α and IL-6 genes. Cell homing of labeled AD-MSCs to the liver tissues was investigated. Hepatic expression of JNK1/2, ERK1/2, p38, Bax, Bcl-2, and cleaved caspase-3 proteins was investigated by western blot analysis. CISP elevated serum ALT and AST activities, reduced albumin level, and remarkably changed the hepatic architecture. It increased the expression TNF-α and IL-6 genes, raised the expression of JNK1/2, ERK1/2, p38, Bax, and cleaved caspase-3 proteins, and diminished the Bcl-2 protein. By contrast, treatment of animals with either AZIL or AD-MSCs dramatically reduced the effects of CISP injection. Moreover, treatment with combination therapy (AZIL.L or H + AD-MSCs) considerably mitigated all previously mentioned alterations superior to AZIL or AD-MSCs alone, which might be attributed to the AZIL-enhanced homing ability of AD-MSCs into the injured liver tissue. In conclusion, the present findings demonstrated that AZIL improves the hepatoprotective potential of AD-MSCs against CISP-induced hepatotoxicity by modulating oxidative stress, mitogen-activated protein kinase, and apoptotic pathways.

Abstract
Eucalyptus, a therapeutic plant mentioned in the ancient Algerian pharmacopeia, specifically two species belonging to the Myrtaceae family, E. radiata and E. cinerea, were investigated in this study for their antibacterial, antioxidant, and anti-inflammatory properties. The study used aqueous extracts (AE) obtained from these plants, and the extraction yields were found to be different. The in vitro antibacterial activity was evaluated using a disc diffusion assay against three typical bacterial strains. The results showed that the two extracts were effective against all three strains. Both extracts displayed significant antioxidant activity compared to BHT. The anti-inflammatory impact was evaluated using a protein (BSA) inhibition denaturation test. The E. radiata extract was found to inhibit inflammation by 85% at a concentration of 250 µg/mL, significantly higher than the Aspirin. All phytoconstituents present good pharmacokinetic characteristics without toxicity except very slight toxicity of terpineol and cineol and a maximum binding energy of -7.53 kcal/mol for its anti-TyrRS activity in silico. The study suggests that the extracts and their primary phytochemicals could enhance the efficacy of antibiotics, antioxidants, and non-steroidal anti-inflammatory drugs (NSAIDs). As pharmaceutical engineering experts, we believe this research contributes to developing natural-based drugs with potential therapeutic benefits.

Abstract
OBJECTIVES The use of medicinal plants for diabetes treatment is increasing owing to their effectiveness and safety compared to synthetic drugs. Thus, the ameliorative effects of Azanza garckeana (F. Hoffm.) fractions in diabetes-induced dyslipidemia, hepatopathy, and nephropathy in rats were evaluated in this study. METHODS Rats with alloxan (120 mg/kg body weight (BW))-induced diabetes were randomized into different groups (n=5) and treated with the crude methanolic extract, and fractions (n-hexane, ethyl acetate, and aqueous fractions) of A. garckeana each at 100, 200, and 400 mg/kg BW. Glibenclamide (5 mg/kg BW) was used as a reference drug, and all treatments were administered orally daily for 6 weeks. RESULTS Our data revealed that treatment with the crude extract caused a dose-dependent hypoglycemic effect of 61.32±3.45%, 76.05±3.05%, and 78.59±5.90% at 100, 200, and 400 mg/kg BW, respectively and improved the BW of the animals. The extract also ameliorated the elevated cholesterol, triglyceride, low-density lipoprotein cholesterol, and increased serum levels of high-density lipoprotein cholesterol compared with untreated control animals. The extract also reversed serum biochemical alterations in aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, creatinine, total and direct bilirubin, urea, and uric acid that were observed in untreated diabetic rats. Interestingly, the A. garckeana fraction also exhibited significant protection against diabetes-induced dyslipidemia, hepatopathy, and nephropathy in rats, with the ethyl acetate fraction exhibiting a remarkable protective effect. The LC-MS characterisation of the active fraction identified the presence of various phenolic and flavonoid compounds that could be responsible for the bioactivity of the fraction. CONCLUSION Collectively, this study suggests the potential application of A. garckeana for effective treatment of diabetic nephropathy, with the ethyl acetate fraction of this plant representing a reserve of potential candidates for developing new drugs.

Abstract
A series of benzimidazole-based Schiff base derivatives (1-18) were synthesized and structurally elucidated through 1H NMR, 13C NMR and HREI-MS analysis. Subsequently, these synthetic derivatives were subjected to evaluation for their inhibitory capabilities against acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). All these derivatives showed significant inhibition against AChE with an IC50 value in the range of 123.9 ± 10.20 to 342.60 ± 10.60 µM and BuChE in the range of 131.30 ± 9.70 to 375.80 ± 12.80 µM in comparison with standard Donepezil, which has IC50 values of 243.76 ± 5.70 µM (AChE) and 276.60 ± 6.50 µM (BuChE), respectively. Compounds 3, 5 and 9 exhibited potent inhibition against both AChE and BuChE. Molecular docking studies were used to validate and establish the structure-activity relationship of the synthesized derivatives.

Abstract
INTRODUCTION Cancer is a significant public health challenge globally, with nearly 2000 lives lost daily in Africa alone. Without adequate measures, mortality rates are likely to increase. The major challenge for cancer care in Africa is equity and prioritization, as cancer is not receiving adequate attention from policy-makers and strategic stakeholders in the healthcare space. This neglect is affecting the three primary tiers of cancer care: prevention, diagnosis, and treatment/management. To promote cancer care equity, addressing issues of equity and prioritization is crucial to ensure that everyone has an equal chance at cancer prevention, early detection, and appropriate care and follow-up treatment. METHODOLOGY Using available literature, we provide an overview of the current state of cancer care in Africa and recommendations to close the gap. RESULTS We highlight several factors that contribute to cancer care inequity in Africa, including inadequate funding for cancer research, poor cancer education or awareness, inadequate screening or diagnostic facilities, lack of a well-organized and effective cancer registry system and access to care, shortage of specialized medical staff, high costs for screening, vaccination, and treatment, lack of technical capacity, poor vaccination response, and/or late presentation of patients for cancer screening. We also provide recommendations to address some of these obstacles to achieving cancer care equity. Our recommendations are divided into national-level initiatives and capacity-based initiatives, including cancer health promotion and awareness by healthcare professionals during every hospital visit, encouraging screening and vaccine uptake, ensuring operational regional and national cancer registries, improving healthcare budgeting for staff, equipment, and facilities, building expertise through specialty training, funding for cancer research, providing insurance coverage for cancer care, and implementing mobile health technology for telemedicine diagnosis. CONCLUSION Addressing challenges to cancer equity holistically would improve the likelihood of longer survival for cancer patients, lower the risk factors for groups that are already at risk, and ensure equitable access to cancer care on the continent. This study identifies the existing stance that African nations have on equity in cancer care, outlines the current constraints, and provides suggestions that could make the biggest difference in attaining equity in cancer care.

Abstract
Hyperlipidemia is a global epidemic that causes various cardiovascular diseases (CVDs). Prunes include fiber and numerous phenolic compounds that decrease cholesterol by decreasing LDL oxidation and supporting heart health. This study examined the therapeutic effects of Prunus domestica prunes on plasma fatty acids in albino rats after ingesting prune pulp. After chemical examination, prunes were proximately examined for nutritional content. Prunus domestica pulp was given to hyperlipidemic rats for two months in a clinical trial. 12 albino rates and divide into 3 groups. First group was controlled, others experimental. The study's 15th, 30th and 60th days evaluated lipid profile. The following study was analyzed using 2 way anova. Prunes have enough fiber, minerals and polyphenols to affect hyperlipidemic rats. GIII rats lower LDL, weight, and HDL more than GI and GII.

Abstract
Silver nanoparticles (AgNPs) have been generally used due to their strong antibacterial, antiviral and antifungal and antimicrobial properties. However, their toxicity is a subject of sustained debate, thus requiring further studies. Hence, this study examines the adverse effects of the sub-dermal administered dose of AgNPs (200 nm) on the liver, kidney and heart of male Wistar rats. Thirty male rats were randomly distributed into six groups of five animals per group. Group A and D served as the control and received distilled water for 14 and 28 days respectively. Groups B and C were sub-dermally exposed to AgNPs at 10 and 50 mg/kg daily for 14 days while E and F were sub-dermally exposed to AgNPs at 10 and 50 mg/kg daily for 28 days. The liver, kidney and heart of the animals were collected, processed and used for biochemical and histological analysis. Our results revealed that the subdermal administration of AgNPs induced significant increased (p < 0.05) activities of aspartate aminotransferase (AST), alanine transferase (ALT), alkaline phosphatase (ALP), urea, creatinine, and malondialdehyde (MDA) while decreasing the levels of glutathione (GSH), catalase (CAT), superoxide dismutase (SOD), and total thiol groups in the rat tissues. Our findings suggest that the subdermal administration of AgNPs induced oxidative stress and impaired the hepatic, renal and cardiac functions of male Wistar rats.

Abstract
Glutathione transferases (GSTs; EC. 2.5.1.18) are a large family of multifunctional enzymes that play crucial roles in the metabolism and inactivation of a broad range of xenobiotic compounds. In the present work, we report the kinetic and structural characterization of the isoenzyme GSTM1-1 from Camelus dromedarius (CdGSTM1-1). The CdGSΤM1-1 was expressed in E. coli BL21 (DE3) and was purified by affinity chromatography. Kinetics analysis showed that the enzyme displays a relative narrow substrate specificity and restricted ability to bind xenobiotic compounds. The crystal structures of CdGSΤM1-1 were determined by X-ray crystallography in complex with the substrate (GSH) or the reaction product (S-p-nitrobenzyl-GSH), providing snapshots of the induced-fit catalytic mechanism. The thermodynamic stability of CdGSTM1-1 was investigated using differential scanning fluorimetry (DSF) in the absence and in presence of GSH and S-p-nitrobenzyl-GSH and revealed that the enzyme’s structure is significantly stabilized by its ligands. The results of the present study advance the understanding of camelid GST detoxification mechanisms and their contribution to abiotic stress adaptation in harsh desert conditions.

Abstract
A respiratory pandemic known as coronavirus disease-19 (COVID-19) has created havoc since it emerged from Wuhan, China. COVID-19 is caused by a newly emerged SARS coronavirus (SARS-CoV) with increased pathogenicity named severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Due to the lack of understanding of the mechanism of pathogenesis, an effective therapeutic option is unavailable. Epidemics described in Unani ancient literature include nazla-e-wabai and humma-e-wabai, and most of the symptoms of COVID-19 resemble nazla-e-wabai. Hence, in light of Unani literature, the treatment of COVID-19 can be managed with the composites prescribed in Unani medicine for nazla-e-wabai. In this study, a structure-based drug design approach was carried out to check the effectiveness of the pharmacologically active constituents of the Unani composites prescribed to treat nazla-e-wabai against SARS-CoV-2. We performed molecular docking of the active constituents of these composites against the main protease (Mpro), a potential drug target in SARS-CoV-2. Using detailed molecular docking analysis, Habb-ul-aas and Tabasheer were identified as potential inhibitors of SARS-CoV-2 Mpro. The active constituents of both these composites bind to the substrate-binding pocket of SARS-CoV-2 Mpro, forming interactions with key residues of the binding pocket. Molecular dynamics (MD) simulation suggested the binding of active constituents of Habb-ul-aas with SARS-CoV-2 Mpro with a strong affinity as compared to the constituents of Tabasheer. Thus, this study sheds light on the use of these Unani composites in COVID-19 therapeutics.Communicated by Ramaswamy H. Sarma.

Abstract
In the present work, a structure-based design approach was used for the generation of a novel variant of synthetic glutathione transferase (PvGmGSTU) with higher sensitivity towards pesticides. Molecular modelling studies revealed Phe117 as a key residue that contributes to the formation of the hydrophobic binding site (H-site) and modulates the affinity of the enzyme towards xenobiotic compounds. Site-saturation mutagenesis of position Phe117 created a library of PvGmGSTU variants with altered kinetic and binding properties. Screening of the library against twenty-five different pesticides, showed that the mutant enzyme Phe117Ile displays 3-fold higher catalytic efficiency and exhibits increased affinity towards α-endosulfan, compared to the wild-type enzyme. Based on these catalytic features the mutant enzyme Phe117Ile was explored for the development of an optical biosensor for α-endosulfan. The enzyme was entrapped in alkosixylane sol-gel system in the presence of two pH indicators (bromocresol purple and phenol red). The sensing signal was based on the inhibition of the sol-gel entrapped GST, with subsequent decrease of released [H+] by the catalytic reaction, measured by sol-gel entrapped indicators. The assay response at 562 nm was linear in the range pH = 4-7. Linear calibration curves were obtained for α-endosulfan in the range of 0-30 μΜ. The reproducibility of the assay response, expressed by relative standard deviation, was in the order of 4.1% (N = 28). The method was successfully applied to the determination of α-endosulfan in real water samples without sample preparation steps.

Abstract
Glutathione S‒transferases (GSTs) are multifunctional enzymes that play an important role in detoxification, cellular signalling, and the stress response. Camelus dromedarius is well-adapted to survive in extreme desert climate and it has GSTs, for which limited information is available. This study investigated the structure-function and thermodynamic properties of a mu-class camel GST (CdGSTM1) at different pH. Recombinant CdGSTM1 (25.7 kDa) was expressed in E. coli and purified to homogeneity. Dimeric CdGSTM1 dissociated into stable but inactive monomeric subunits at low pH. Conformational and thermodynamic changes during the thermal unfolding pathway of dimeric and monomeric CdGSTM1 were characterised via a thermal shift assay and dynamic multimode spectroscopy (DMS). The thermal shift assay based on intrinsic tryptophan fluorescence revealed that CdGSTM1 underwent a two-state unfolding pathway at pH 1.0-10.0. Its Tm value varied with varying pH. Another orthogonal technique based on far-UV CD also exhibited two-state unfolding in the dimeric and monomeric states. Generally, proteins tend to lose structural integrity and stability at low pH; however, monomeric CdGSTM1 at pH 2.0 was thermally more stable and unfolded with lower van't Hoff enthalpy. The present findings provide essential information regarding the structural, functional, and thermodynamic properties of CdGSTM1 at pH 1.0-10.0.

Abstract
Erwinia carotovora, a widespread plant pathogen that causes soft rot disease in many plants, is considered a major threat in agriculture. Bacterial glutathione transferases (GSTs) play important roles in a variety of metabolic pathways and processes, such as the biodegradation of xenobiotics, protection against abiotic stress, and resistance against antimicrobial drugs. The GST family of canonical soluble enzymes from Erwinia carotovora subsp. atroseptica strain SCRI1043 (EcaGSTs) was investigated. Genome analysis showed the presence of six putative canonical cytoplasmic EcaGSTs, which were revealed by phylogenetic analysis to belong to the well-characterized GST classes beta, nu, phi, and zeta. The analysis also revealed the presence of two isoenzymes that were phylogenetically close to the omega class of GSTs, but formed a distinct class. The EcaGSTs were cloned and expressed in Escherichia coli, and their catalytic activity toward different electrophilic substrates was elucidated. The EcaGSTs catalyzed different types of reactions, although all enzymes were particularly active in reactions involving electrophile substitution. Gene and protein expression profiling conducted under normal culture conditions as well as in the presence of the herbicide alachlor and the xenobiotic 1-chloro-2,4-dinitrobenzene (CDNB) showed that the isoenzyme EcaGST1, belonging to the omega-like class, was specifically induced at both the protein and mRNA levels. EcaGST1 presumably participates in counteracting the xenobiotic toxicity and/or abiotic stress conditions, and may therefore represent a novel molecular target in the development of new chemical treatments to control soft rot diseases.

Abstract
In the present study, a structure-based approach was exploited for the in silico design of a nucleotide coenzyme mimetic ligand. The enzyme formate dehydrogenase (FDH) was employed as a model in our study. The biomimetic ligand was designed and synthesized based on a tryptamine/3-aminopropylphosphonic acid bi-substituted 1,3,5-triazine (Trz) scaffold (Tra-Trz-3APP), which potentially mimics the interactions of NAD+-FDH complex. Molecular docking studies of the biomimetic ligand predicted that it can occupy the same binding site as the natural coenzyme. Molecular modeling and dynamics simulations revealed that the ligand binds in an energetically more stable pose in the FDH binding site, as it adopts a more twisty conformation, compared to the natural coenzyme. Study of the FDH/Tra-Trz-3APP-Sepharose interaction, through adsorption equilibrium studies and site-directed mutagenesis of selected FDH coenzyme binding residues, provided additional experimental evidences of the specificity of the interaction. The Tra-Trz-3APP-Sepharose biomimetic adsorbent was further evaluated towards a range of different dehydrogenases and was exploited for the development of a single-step purification protocol for FDH. The protocol afforded enzyme with high yield and purity, suitable for analytical and industrial purposes.

Abstract
Polymorphisms of some genes of the renin-angiotensin system (RAS), such as angiotensinogen (AGT; M235T), angiotensin II type 2 receptor (AT2; C3123A), and angiotensin-converting enzyme (ACE; insertion/deletion (I/D)) are involved in the development and progression of coronary artery disease (CAD) in diabetic individuals. In the present study, we aimed to determine whether three polymorphisms, AGT-M235T, AT2-C3123A, and ACE I/D are associated with CAD in Saudi patients with type two diabetes mellitus (T2DM). In 266 patients with CAD (169 patients with T2DM and 97 without T2DM), restriction fragment length polymorphism analysis was used to detect polymorphisms in the three RAS genes. Within the CAD+T2DM group, for the ACE gene (I/D), homozygous DD was found in 65.68%, 25.44% carried the heterozygous ID, and 8.88% carried the homozygous II. Within the CAD-T2DM group, DD was found in 55.67%, 26.8% carried the ID, and 17.53% carried the II. The odds ratio (OR) of the ACE ID+DD vs. II was 2.18, with a 95% confidence interval (CI) of 1.04-4.60, and P = 0.04. Thus, we found an association between the ACE DD polymorphism and CAD in Saudi patients with T2DM, but not between the AT2 C3123A and AGT M235T polymorphisms and CAD.

Abstract
BACKGROUND The polymorphisms in the components of the renin-angiotensin system (RAS) are important in the development and progression of coronary artery disease (CAD) in some individuals. Our objectives in the present investigation were to determine whether three RAS polymorphisms, angiotensin-converting enzyme insertion/deletion (ACE I/D), angiotensin receptor II (Ang II AT2 - C3123A) and angiotensinogen (AGT-M235T), are associated with CAD in the Saudi population. We recruited 225 subjects with angiographically confirmed CAD who had identical ethnic backgrounds and 110 control subjects. The polymerase chain reaction-restriction fragment length polymorphisms (RFLP) technique was used to detect polymorphisms in the RAS gene. RESULTS Within the CAD group, for the ACE I/D genotype, DD was found in 64.4%, 26.3% carried the ID genotype, and 9.3% carried the II genotype. Within the control group, the DD genotype was found in 56.4%, 23.6% carried the ID genotype, and 20% carried the II genotype. The odds ratio (OR) of the ACE DD vs II genotype with a 95% confidence interval (CI) was 2.45 (1.26-4.78), with p = 0.008. For the Ang II AT2 receptor C3123A genotype, within the CAD group, CC was found in 39.6%, 17.8% carried the CA genotype, and 42.6% carried the AA genotype. Within the control group, CC was found in 39.1%, 60.9% carried the CA genotype, and there was an absence of the AA genotype. The OR of the Ang II AT2 receptor C3123A CC vs AA genotypes (95% CI) was 0.01, with p = 0.0001. A significant association with CAD was shown. For the AGT-M235T genotype, within the CAD group, MM was found in 24.0%, 43.6% carried the MT genotype and 32.4% carried the TT genotype. Within the control group, MM was found in 26.4%, 45.5% carried the TT genotype and 28.2% carried the MT genotype. The OR of MM vs TT (95% CI) was 0.79 (0.43 to 1.46), which was insignificant. CONCLUSIONS There is an association between the ACE I/D and Ang II AT2 receptor C3123A polymorphisms and CAD, however, no association was detected between the AGT M235T polymorphism and CAD in the Saudi population.

Abstract
The domesticated one-humped camel, Camelus dromedarius, is one of the most important animals in the Arabian Peninsula. For most of its life, this species is exposed to both intrinsic and extrinsic genotoxic factors that cause gross DNA alterations in many organisms. GST enzymes constitute an important supergene family involved in protection against the deleterious effects of oxidative stress and xenobiotics. Cloning the camel mitochondrial GST kappa (GSTK) gene and comparing its structural similarities with different species may aid in understanding its evolutionary relics. We cloned the camel GSTK using RT-PCR. This yielded an open reading frame of 678 nucleotides, encoding a protein of 226 amino acid residues. In a comparative analysis, the cloned GSTK was used to screen orthologues from different organisms. Phylogenetic analysis demonstrated that the camel GSTK apparently evolved from an ancestral GSTK gene that predated the appearance of vertebrates, and it grouped with pig, cattle, dog, horse, human and monkey GSTKs. The calculated molecular weight of the translated ORF was 25.52 kDa and the isoelectric point was 8.4. The deduced cGSTK sequence exhibited high identity with many mammals, such as Bactrian camel (99.55%), pig, cattle and human (>74%), and lower identity with other unrelated organisms, such as frog (Xenopus tropicalis, 61%), chicken (Gallus gallus, 57%), salmon (Salmo salar, 49%), sponge (Amphimedon queenslandica, 46%), tick (Amblyomma maculatum, 45%) and roundworm (Caenorhabditis elegans, 33%). A 3D structure was built based on the crystal structure of the human and rat enzymes. The levels of cGSTK expression in five camel tissues were examined via real-time PCR. The highest level of cGSTK transcripts was found in the camel liver, followed by the testis, spleen, kidney and lung.

Abstract
The domesticated one-humped Arabian camel, Camelus dromedarius, is one of the most important animals in the Arabian Peninsula. Most of its life, this animal is exposed to both intrinsic and extrinsic genotoxic factors that are known to cause gross metabolic alterations in many organisms. This study determined the full length coding sequence of 3 cytochrome P450s cDNAs; namely, CYP450 1A1, CYP450 2C and CYP450 3A using reverse transcription polymerase chain reaction. The C. dromedarius CYP450s 1A1, 2C, and 3A have open reading frames of 1563, 1473, and 1566 bp and cDNAs that encode proteins of 520, 490, and 521 amino acid residues, respectively. The molecular weights calculated for CYP1A1, 2C, and 3A were found to be 58.651, 56.03, and 58.594 kDa, while the predicted calculated isoelectric points using a computer algorithm were 7.315, 6.579, and 9.46. The deduced amino acid sequences of these CYPs showed the membrane anchored signal peptide, the conserved proline-rich amino terminus and the characteristic heme-binding signature localized near the carboxy terminus of the protein.

Abstract
Lipoprotein lipase (LPL) plays a central role in lipoprotein metabolism by hydrolyzing the core triglycerides (TGs) of circulating chylomicrons and very-low-density lipoprotein (VLDL). The effects of LPL polymorphisms on lipid levels and coronary artery disease (CAD) have been inconsistent among studies and populations. To assess the lipid profiles and distributions of three LPL gene polymorphisms in Saudi patients with CAD, the HindIII, PvuII and Ser447Ter polymorphisms in the LPL gene were analyzed in 226 patients with CAD and 110 controls. Polymerase chain reaction-restriction fragment length polymorphism was used to detect LPL gene polymorphisms. The plasma lipid profiles of the patients were determined using standard enzymatic methods. Patients in the CAD group had significantly higher triglyceride (TG), total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels than controls irrespective of the HindIII, PvuII or Ser447Ter genotype. Compared to the findings in controls, the HindIII TT, PvuII TC and Ser447Ter CC genotypes were associated with significantly reduced high-density lipoprotein cholesterol (HDL-C) levels in patients with CAD (P<0.0001). In summary, there are associations between LPL gene variants and high plasma TG, TC and LDL-C levels as well as low HDL-C levels.

Abstract
Superoxide dismutase (SOD) is the first line of defense against oxidative stress induced by endogenous and/or exogenous factors and thus helps in maintaining the cellular integrity. Its activity is related to many diseases; so, it is of importance to study the structure and expression of SOD gene in an animal naturally exposed most of its life to the direct sunlight as a cause of oxidative stress. Arabian camel (one humped camel, Camelus dromedarius) is adapted to the widely varying desert climatic conditions that extremely changes during daily life in the Arabian Gulf. Studying the cSOD1 in C. dromedarius could help understand the impact of exposure to direct sunlight and desert life on the health status of such mammal. The full coding region of a putative CuZnSOD gene of C. dromedarius (cSOD1) was amplified by reverse transcription PCR and cloned for the first time (gene bank accession number for nucleotides and amino acids are JF758876 and AEF32527, respectively). The cDNA sequencing revealed an open reading frame of 459 nucleotides encoding a protein of 153 amino acids which is equal to the coding region of SOD1 gene and protein from many organisms. The calculated molecular weight and isoelectric point of cSOD1 was 15.7 kDa and 6.2, respectively. The level of expression of cSOD1 in different camel tissues (liver, kidney, spleen, lung and testis) was examined using Real Time-PCR. The highest level of cSOD1 transcript was found in the camel liver (represented as 100%) followed by testis (45%), kidney (13%), lung (11%) and spleen (10%), using 18S ribosomal subunit as endogenous control. The deduced amino acid sequence exhibited high similarity with Cebus apella (90%), Sus scrofa (88%), Cavia porcellus (88%), Mus musculus (88%), Macaca mulatta (87%), Pan troglodytes (87%), Homo sapiens (87%), Canis familiaris (86%), Bos taurus (86%), Pongo abelii (85%) and Equus caballus (82%). Phylogenetic analysis revealed that cSOD1 is grouped together with S. scrofa. The predicted 3D structure of cSOD1 showed high similarity with the human and bovine CuZnSOD homologues. The Root-mean-square deviation (rmsd) between cSOD1/hSOD1 and cSOD1/bSOD1 superimposed structure pairs were 0.557 and 0.425 A. The Q-score of cSOD1-hSOD1 and cSOD1-bSOD1 were 0.948 and 0.961, respectively.

Abstract
p53 is a critical player in the prevention of tumor development. It can contribute directly to DNA repair and inhibition of angiogenesis and subsequently to the induction of apoptosis. The regulation of p53 expression is mediated by the transcription factor NF-kappaB. This includes regulation of p53 protein stability, control of its subcellular localization and conformational changes that allow activation of the DNA binding activity of p53. Rat hepatocytes were isolated from male Wistar rats following collagenase perfusion of liver. We examined the change in the expression level of p53 by western blotting in hepatocytes and its effect on apoptosis as a response of treatment with D-galactosamine, prostaglandin E1 and/or the Proteosome Inhibitor (PSI). A kinetic study of the extracellular lactate dehydrogenase activity, NF-kappaB activation, induced nitric oxide synthase expression and nitric oxide production was carried out in hepatocytes. The addition of prostaglandin E1 to control and D-galactosamine-treated hepatocytes increased p53 expression in the cytoplasm during 24 h. While the addition of PSI in the absence of prostaglandin E1 decreased p53 expression at 5 mM D-galactosamine. This inhibition is reversed in the presence of prostaglandin E1 at 5 and 40 mM D-galactosamine. The protective action of prostaglandin E1 against the apoptotic effect of D-galactosamine is mediated by NF-kappaB activation, induced nitric oxide synthase and p53 expression.

Abstract
The molybdenum cofactor (Moco) forms the catalytic site in all eukaryotic molybdenum enzymes and is synthesized by a multistep biosynthetic pathway. The mechanism of transfer, storage, and insertion of Moco into the appropriate apo-enzyme is poorly understood. In Chlamydomonas reinhardtii, a Moco carrier protein (MCP) has been identified and characterized recently. Here we show biochemical evidence that MCP binds Moco as well as the tungstate-substituted form of the cofactor (Wco) with high affinity, whereas molybdopterin, the ultimate cofactor precursor, is not bound. This binding selectivity points to a specific metal-mediated interaction with MCP, which protects Moco and Wco from oxidation with t((1/2)) of 24 and 96 h, respectively. UV-visible spectroscopy showed defined absorption bands at 393, 470, and 570 nm pointing to ene-diothiolate and protein side-chain charge transfer bonds with molybdenum. We have determined the crystal structure of MCP at 1.6 Angstrom resolution using seleno-methionated and native protein. The monomer constitutes a Rossmann fold with two homodimers forming a symmetrical tetramer in solution. Based on conserved surface residues, charge distribution, shape, in silico docking studies, structural comparisons, and identification of an anionbinding site, a prominent surface depression was proposed as a Moco-binding site, which was confirmed by structure-guided mutagenesis coupled to substrate binding studies.

Abstract
Simple reproducible procedures for purification of the main soluble (S) and ionically bound (IB) cationic peroxidase isoenzymes from turnip roots were established. The procedures included ammonium sulfate precipitation of the isoenzymes, chromatographic separation of the main isoenzymes using cellulose phosphate columns and purification to homogeneity by hydrophobic interaction chromatography on phenyl Sepharose columns. The specific activity of the phenyl Sepharose purified S and IB isoenzymes were 2760 and 896 units/mg protein with 140 and 4.8 fold increase over the crude extract and 38 and 13% recovery. The pH maxima and K(m) for phenol and H2O2 of purified S and IB were determined.
