Objective: To determine the final year pharmacy undergraduate students' attitudes toward research after completing a research project. Methods: A research project was introduced in the final year of the PharmD program in January 2022. After a period of one year, in Janurary 2023, students submitted their final research to the faculty members. The survey was conducted from 1st March to 30st April 2023 using a study tool that contained items asking students' demographic, their research perceptions, attitude and experience, and also motivation/barriers faced during the research project. Descriptive and t-test statistics were utilized to compare the means of subgroups at a level of significance, i.e., p < 0.05. The data were also analyzed using Goodman and Kruskal's gamma and Mann-Whitney U test. Results: Majority of the students (93.8%) agreed regarding the significance of research in the pharmacy profession. Students were found to have their projects a worthwhile learning opportunity (94.2%). Students' motivation to execute research project stems from mandatory curriculum courses, improving clinical or hospital pharmacist training and fulfilling research skills (90%). Barriers hindered include lack of training, time, and patient follow-up (approximately 70%). Conclusion: The current study's finding was concluded with the fact that research is a valuable component of a well-rounded education and can enhance a pharmacist's skills. However, they need a combination of formal education and practical experience to pursue a profession in pharmacy.

In silico and in vitro assessment of drugs potentially causing adverse effects by inhibiting CYP17A1.

Cytochrome P450 enzymes (CYPs) play a crucial role in the metabolism and synthesis of various compound classes. While drug-metabolizing CYP enzymes are frequently investigated as anti-targets, the inhibition of CYP enzymes involved in adrenal steroidogenesis is not well studied. The steroidogenic enzyme CYP17A1 is a dual-function enzyme catalyzing hydroxylase and lyase reactions relevant for the biosynthesis of adrenal glucocorticoids and androgens. Inhibition of CYP17A1-hydroxylase leads to pseudohyperaldosteronism with subsequent excessive mineralocorticoid receptor activation, hypertension and hypokalemia. In contrast, specific inhibition of the lyase function might be beneficial for the treatment of prostate cancer by decreasing adrenal androgen levels. This study combined in silico and in vitro methods to identify drugs inhibiting CYP17A1. The most potent CYP17A1 inhibitors identified are serdemetan, mocetinostat, nolatrexed, liarozole, and talarozole. While some of these drugs are currently under investigation for the treatment of various cancers, their potential for the treatment of prostate cancer is yet to be explored. The DrugBank database was screened for CYP17A1 inhibitors, to increase the awareness for the risk of drug-induced pseudohyperaldosteronism and to highlight drugs so far unknown for their potential to cause side effects resulting from CYP17A1 inhibition.

The beneficial effect of Allium Cepa bulb extract on reproduction of rats; A two-generation study on fecundity and sex hormones.

Allium Cepa Linn. (Onions) has extensively been used in traditional medicine, is one of the important Allium species regularly used in our daily diet, and has been the source of robust phenolic compounds. The current study is intended to evaluate the fecundity-enhancing effect of A. Cepa on the reproductive performance of two successive generations of rats; F0 and F1. A. Cepa extract was initially tested for in vitro antioxidant assay via DPPH and ROS, followed by in vivo toxicity testing. In the fecundity assessment, eighteen pairs of male and female rats (n = 36, 1:1, F0 generation) were divided into three groups and dosed with 75mg/kg and 150 mg/kg daily of A. Cepa extract and saline respectively, up to pre-cohabitation, cohabitation, gestation and lactation period. The reproductive performance, including body weight, live birth index, fertility index, and litter size, was assessed. Various parameters like Hematological, Hormonal (FSH, LH, Testosterone, estradiol), antioxidant markers (SOD, Glutathione peroxidase) and lipid profile of F0 and F1 generations were assessed with evaluation of histopathology of male and female organs. Ethanolic extract of A. Cepa showed the greatest antioxidant potential in DPPH and ROS methods. The continued exposure of the F0 and F1 generations to A. Cepa extract did not affect body weight, fertility index, litter size, and survival index. However, semen pH, sperm motility, sperm count, sperm viability, and semen volume were significantly improved in both generations. We have found pronounced fecundity outcomes in both genders of F0 and F1 generations with A. Cepa 150mg/kg/day extract as compared to control. Results showed that A. Cepa significantly increased (P < 0.05) hemoglobin, follicular stimulating hormone (FSH), luteinizing hormone (LH), plasma testosterone and glutathione peroxidase activities, while total lipid, LDL, and cholesterol were significantly decreased (P < 0.05) in both generations. Histology of both generations of animals reveals enhanced spermatogenesis and enhanced folliculogenesis with improved architecture. Altogether, the present results suggest that A. Cepa extract improved fecundity in both male and female rats by improving hormonal activities and oxidative stress.

Shark fish oil prevents scopolamine-induced memory impairment in an experimental model.

Fish oil has been known for its antioxidant, cardioprotective, anti-inflammatory, and neuroprotective characteristics due to the presence of polyunsaturated fatty acids (PUFAs) that are essential for optimal brain function and mental health. The present study investigated the effect of Carcharhinus Bleekeri (Shark Fish) oil on learning and memory functions in scopolamine-induced amnesia in rats. Locomotor and memory-enhancing activity in scopolamine-induced amnesic rats was investigated by assessing the open field and passive avoidance paradigm. Forty male Albino mice were divided into 4 equal groups (n = 10) as bellow: 1 - control (received 0.9% saline), 2 - SCOP (received scopolamine 2 mg/kg for 21 days), 3 - SCOP + SFO (received scopolamine and fish oil 5 mg/kg/ day for 21 days), 4 - SCOP + Donepezil groups (received 3 mg/kg/day for 21 days). SFO produced significant (P < 0.01) locomotor and memory-enhancing activities in open-field and passive avoidance paradigm models. Additionally, SFO restored the Acetylcholine (ACh) concentration in the hippocampus (p < 0.05) and remarkably prevented the degradation of monoamines. Histology of brain tissue showed marked cellular distortion in the scopolamine-treated group, while the SFO treatment restored distortion in the brain's hippocampus region. These results suggest that the SFO significantly ameliorates scopolamine-induced spatial memory impairment by attenuating the ACh and monoamine concentrations in the rat's hippocampus.

Comparative analysis of antioxidant, antidiabetic and analgesic activity of Callestemon viminalis L. and Alcea rosea L. leaves extracts.

High levels of reactive oxygen species (ROS) in the body and diabetes are key factors for the development of hypercholesteremia and related neuropathic pains. Current study aimed to compare the antioxidant, antidiabetic and analgesic activities of aqueous methanolic extracts of C. viminalis L. and A. rosea L. leaves. HPLC method was used for phenolic content evaluation. Antioxidant capacity was determined by DPPH and analgesic activity was performed via acetic acid induced writhing reflex test. Whereas the antidiabetic activity was performed on Alloxan induced diabetes model. HPLC analysis indicated the presence of phenols in both extracts. Based on DPPH radical scavenging activity, C. viminalis and A.rosea L. both leaves extracts showed strong scavenging activity (IC50, 11.96±0.64lg/mL) and (IC50, 10.11±0.74lg/mL) respectively. Antidiabetic effect of C. viminalis L and A. rosea L. were also significant (p<0.05). Further biochemical analysis showed both leaves extracts significantly (P<0.05) reduces glucose, Low density lipid (LDL), triglycerides (TG), total cholesterol (TC) and urea while high density lipid (HDL) were improved. In writhing reflex test both extracts exhibited significant (P<0.01) analgesic activity which was comparable to Aspirin. In conclusion both C. viminalis L. and A. rosea L. leaves extracts displayed significant antioxidant, analgesic and antidiabetic activity.

Molecular docking analysis of fluoroquinolones and other natural and synthetic compounds with the HCV NS3 helicase.

It is of an interest to document the molecular docking analysis of fluoroquinolones and other natural and synthetic compounds with the HCV NS3 helicase. Data shows that three fluoroquinolones interacted with the NS3 helicase in the catalytic region, targeting some of the amino acids known to play a crucial role in NS3 helicase activity. Similarly, binding energy shows that the fluoroquinolones were comparable to the thiazolpiperazinyl derivatives, while superior to several of the synthetic and natural derivatives. The results show three fluoroquinolones to be potent helicase inhibitors that can be repurposed as supplemental therapy against HCV especially in cases non-responsive to DAAAs.

Phylogenetic Characterization of HIV-1 Sub-Subtype A1 in Karachi, Pakistan.

(1) Background: HIV-1 sub-subtype A1 is common in parts of Africa, Russia, former Soviet Union countries, and Eastern Europe. In Pakistan, sub-subtype A1 is the predominant HIV-1 subtype. Preliminary evidence suggests that distinct strains of HIV-1 sub-subtype A1 are circulating in Pakistan; however, an in-depth molecular phylogenetic characterization of HIV-1 sub-subtype A1 strains in Pakistan have not been presented. We performed a detailed characterization of the HIV-1 sub-subtype A1 epidemic in Pakistan using state-of-the-art molecular epidemiology and phylodynamics. (2) Methods: A total of 143 HIV-1 sub-subtype A1 gag sequences, including 61 sequences generated specifically for this study from PLHIVs part of our cohort, representing all sub-subtype A1 gag sequences from Pakistan, were analyzed. Maximum-likelihood phylogenetic cluster analysis was used to determine the relationship between Pakistani sub-subtype A1 strains and pandemic sub-subtype A1 strains. Furthermore, we used signature variation, charge distribution, selection pressures, and epitope prediction analyses to characterize variations unique to Pakistani HIV-1 strains and establish the association between signature variations and Gag epitope profile. (3) Results: The HIV-1 sub-subtype A1 sequences from Pakistan formed three main clusters: two that clustered with Kenyan sequences (7 and 10 sequences, respectively) and one that formed a Pakistan-specific cluster of 123 sequences that were much less related to other sub-subtype A1 sequences available in the database. The sequences in the Pakistan-specific cluster and the Kenyan reference strains exhibited several signature variations, especially at amino acid positions 312, 319, 331, 372, 373, 383, and 402. Structural protein modeling suggested that amino acid changes in these positions result in alterations of the Gag protein structure as well as in Gag-specific T-cell epitopes. (4) Conclusions: Our results suggest that the majority of the Pakistan HIV-1 sub-subtype A1 strains were unique to Pakistan and with a specific mutation pattern in Gag.

Validation of questionnaire regarding online teaching (QOT) during Covid-19 in Karachi, Pakistan.

The present study involved an extra-cultural adaptation and validation of questionnaire regarding online teaching (QOT) to know faculty perception, attitude and experiences of online teaching. Cronbach's alpha was determined for assessing internal reliability of QOT and found to be 0.886, confirmed that the scale have good reliability. Factor Analysis of the scale (Principal Component Analysis) was used to examine factor structure and then trailed by varimax rotation. The items were allocated four sub scales. A survey technique was used for the validation of QOT and the survey was conducted during September-December' 2020 in private and public universities of Karachi to determine the pharmacy faculty's perception and experience regarding online teaching. Approximately 35% responded that "It is very easy to prepare and deliver an online course" and 45% opined that "The universities offering Pharm.D should adopt the use of e-learning for teaching in future to complement traditional teaching". Majority of the faculty were in favor of starting online teaching during pandemic to complete semester on time (72%). However, in-campus courses contribute more to students' learning than online courses in pharmaceutical sciences (65.5%). The present study summarizes that academic staff did opt online teaching over one-to-one teaching in the lock down situation during Covid-19 pandemic however, they agreed not to replace traditional teaching to online teaching. Teachers recognized some difficulties and challenges during online teaching including difficulty in preparing lecture for online teaching than traditional classroom teaching, shortage of long time training sessions. Female teachers were inclined to online teaching than male and lecturers tend to prefer online teaching compared to senior teachers. Universities and administration should take imperative acts for improving online teaching for better learning during lock down or any other situation where social distancing is required.

Comparative antioxidant and analgesic effect of sesame oil, fish oil and their combination in experimental animal model.

Natural oils are rich in polyunsaturated fatty acids (PUFs) like omega 3, omega 6 and other nutrients that boost physical and mental health. Traditionally these oils have been used to treat joint pain associated with several inflammatory conditions. In this study, we investigated the antioxidant and analgesic properties of the sesame oil (SO), fish oil (FO) and combination of these two oils (SO+FO). Different concentrations of the SO, FO and SO+FO combination 0.02-4mg/ml were used for assessing the free radical scavenging activity by DPPH method and the IC50 value was calculated. Acetic acid-induced abdominal writhing test, tail immersion and hot plate models were used to determined analgesic effect. Results showed that both oils were well tolerated as no signs of toxicity or death were noticed during the observational study period. SO+FO combination showed the best antioxidant properties as shown by DPPH assay. Similarly in analgesic models, SO and FO significantly reduced the number of abdominal contractions (p<0.05) however, SO+FO (1:1) exhibited highly significant results (p<0.001) in writhing reflex test. Furthermore, SO and FO both increased the reaction time on a hot plate as well as in tail flick test (p<0.05) whereas, SO+FO significantly increased reaction time (p<0.001) in hot plate and in tail flick test as compared to SO and FO single treatments. Conclusively, our results suggest that the combination of both oils (SO+FO) exhibited significant antioxidant and analgesic potential that it could be considered as one of the active combinations for relieving pain in adjunctive treatment for joint pain associated with rheumatoid arthritis.

Phytochemical analysis and biological activities of "Cherchoomoro" (Nepeta adenophyta Hedge).

ETHNOPHARMACOLOGICAL RELEVANCE: Nepeta adenophyta Hedge (Lamiaceae) is an endemic therapeutic herb from Astore, Gilgit (Pakistan). This plant species has been reported among the local communities, especially for treating abdominal pain, kidney pain, menstrual pain, headache, and controlling bleeding disorders. Therefore, the scientific basis is provided for the relief of pain as it is used in various pain management among the natives, especially as ethnogynecological herbal remedy. AIM OF THE STUDY: The present study investigates the analgesic and anti-inflammatory effects of the ethanolic extract of N. adenophyta in animal models. Furthermore, the extract was also studied to determine their valuable phytoconstituents. MATERIAL AND METHODS: The biological effects were determined via tail-flick, hot plate, and acetic-acid-induced abdominal writhing methods. At the same time, anti-inflammatory activity was assesed via oxidative burst and antioxidant DPPH assay. Gas chromatography-mass spectrometry (GC-MS), and liquid chromatography-mass spectrometry (LC-MS) techniques were employed to understand the phytochemicals present in the crude ethanolic extract of Nepeta adenophyta. RESULTS: In the current study, Nepeta adenophyta extract exhibited potent analgesic and anti-inflammatory effects on different pain models and indicated that the analgesic effect of N. adenophyta extract is mediated both in central and peripheral ways. Dose-dependent and significant (P < 0.05) increases were shown in pain threshold, at 45 min post-treatment, with 20 and 40 mg/kg of the extract in the tail-flick model. The effects of the extract were similar to aspirin but lower to those by morphine (2.5 mg/kg) in the same tests. The extract (20-40 mg/kg) showed dose-dependent inhibition of writhing with a significant (P < 0.001) increase protection against thermal stimuli in hot plate test as compared to control and similar to aspirin and morphine. Further, the anti-inflammatory activity of the crude in oxidative burst and DPPH assays showed significant inhibitory activity. The chemical profile analysis showed major phytochemicals, including long chain derivatives of alkane and alcohol, phenolics, naphthalene, naphthopyran, androsten phenanthrenone, nepetalactones, flavonoids etc. CONCLUSIONS: Nepeta adenophyta Hedge is suggested as a natural alternative for mild pain relief. Our findings endorse the folklore use of N. adenophyta in different pain managements which can be attributed to the presence of polyphenolic compounds, naphthalene derivatives, flavanoids and nepetalactones etc.

In silico investigation on alkaloids of Rauwolfia serpentina as potential inhibitors of 3-hydroxy-3-methyl-glutaryl-CoA reductase.

Present work aimed to investigate the in silico activity of the alkaloids of roots of Rauwolfia serpentina as inhibitors of 3-hydroxy-3-methyl-glutaryl-CoA reductase (HMGCR). For this purpose, the three-dimensional (3D) structure of the protein HMGCR (PDB ID: 1HW9) was downloaded from Protein Data Bank (PDB) database, as a target enzyme. The structures of twelve alkaloids from the roots of R. serpentina were selected as ligands and docked with the selected HMGCR enzyme using Molegro Virtual Docker (MVD) software. The software 'MVD' computes the binding (atom) energies of selected protein (enzyme) and each ligand at minimum energetic conformation state by using the PLP (Piecewise Linear Potential) scoring mechanism. Docking results of twelve tested alkaloids showed that five alkaloids including compound 1 (ajmalicine), 2 (reserpine), 3 (indobinine), 4 (yohimbine), and 5 (indobine) have displayed the highest MolDock scores and best fit within the prominent active site residues (positioned between 684 and 692 of cis-loop) of HMGCR. According to the lowest MolDock energies obtained through non-covalent interactions of alkaloids with HMGCR, these are characterized to be the potential inhibitors of HMGCR. Therefore, the alkaloids from R. serpentina can effectively suppress the cholesterol biosynthesis pathway through inhibition of HMGCR and can serve as potential lead compounds for the development of new drugs for the treatment of hyperlipidaemia.

Effect of Methylphenidate and buspirone-methylphenidate co-administration on biochemical and hematological parameters in rats: Implications for safe and confrontational use.

Methylphenidate (MPH) is a psychostimulant, beneficial in attention deficit hyperactivity disorder (ADHD). Previously it has been shown that MPH-induced locomotor sensitization could be attenuate by buspirone co administration however the effect of chronic MPH and co-administration of MPH-buspirone on biochemical and hematological parameters are unknown. This study is designed to investigate these parameters after long term administration of MPH, Buspirone and their combination in rats. 40 male Wister rats were divided in to 4 groups, and treated with saline, MPH (2mg/kg/day), Buspirone (10mg/kg/day) and MPH-Buspirone co-administration (2mg/kg/day ±10mg/kg/day; respectively) up to six weeks. Administration of MPH significantly increase blood glucose level in saline treated control rats, however co-administration of MPH-buspirone exhibited less effect on blood glucose levels. Serum creatinine levels significantly decreased in all treated groups as compared to control but highly significant results were seen with combination treatment. Co-administration of MPH-buspirone and buspirone treated rats exhibited increased cholesterol and hemoglobin values. All treated groups showed increased values of hematocrit, MCV, MCH and MCHC compared to control group. RBCs and WBC's count were decreased in all treated groups. The platelet count rose significantly by Buspirone and MPH-buspirone administration, while MPH showed decreased platelet count. Thus, results suggested that prolong co-administration of MPH-buspirone is safe and effective for ADHD patients by preventing adverse effects not only on behavioral but also on biochemical and hematological parameter.

Evaluation of Acute and Chronic Antidiabetic Activity of Ivy (Hedera helix L.) Aqueous Leaf Extract in Rat Model.

BACKGROUND AND OBJECTIVE: Hedera helix L. (Ivy) has been utilized as an alternative medicine for cough however, through extensive literature search; we found no reported activity of ivy on α-glucosidase inhibition, HbA1c levels and its protective effect on vital organs. Therefore, the present study aimed to evaluate the antidiabetic and protective effect of ivy in alloxan induced rat model. MATERIALS AND METHODS: The hypoglycemic activity of ivy was examined in normoglycemic, glucose overloaded and alloxan-induced rats. The antidiabetic potential was also confirmed by estimation of HbA1c and α-glucosidase inhibitory activity. RESULTS: Results of acute and chronic study revealed that ivy produced highly significant decline (p<0.01) in fasting and post-prandial blood sugar levels as compared to diabetic control and standard group respectively. Furthermore, highly significant decline (p<0.01) in HbA1c levels were seen after chronic administration of ivy indicating its therapeutic effect in lowering HbA1c levels during long term use. It was found that ivy produced stronger and highly significant (p<0.05) inhibition of α-glucosidase activity than the standard agent acarbose at 500 µg mL-1. CONCLUSION: The histopathological studies of vital organs revealed protective effect of ivy via maintaining the normal architecture as compared to alloxan model. Hence, our findings support the potential use of ivy for diabetes management.

An in silico approach to analyze HCV genotype-specific binding-site variation and its effect on drug-protein interaction.

Genotype variation in viruses can affect the response of antiviral treatment. Several studies have established approaches to determine genotype-specific variations; however, analyses to determine the effect of these variations on drug-protein interactions remain unraveled. We present an in-silico approach to explore genotype-specific variations and their effect on drug-protein interaction. We have used HCV NS3 helicase and fluoroquinolones as a model for drug-protein interaction and have investigated the effect of amino acid variations in HCV NS3 of genotype 1a, 1b, 2b and 3a on NS3-fluoroquinolone interaction. We retrieved 687, 667, 101 and 248 nucleotide sequences of HCV NS3 genotypes 1a, 1b, 2b, and 3a, respectively, and translated these into amino acid sequences and used for genotype variation analysis, and also to construct 3D protein models for 2b and 3a genotypes. For 1a and 1b, crystal structures were used. Drug-protein interactions were determined using molecular docking analyses. Our results revealed that individual genotype-specific HCV NS3 showed substantial sequence heterogeneity that resulted in variations in docking interactions. We believe that our approach can be extrapolated to include other viruses to study the clinical significance of genotype-specific variations in drug-protein interactions.

Comparison of the antidepressant like activity of homeopathic remedies (Argentum nitricum, Staphysagria and Ignatia amara) and their effect on the behavior of rodents.

The majority of the world population suffers from mental and behavioral disorder. It is the need of the time to find an alternate of presently available medicines in order to decrease the medical expense. Homeopathic remedies are available and prescribed by homeopaths for treatment of anxiety and depression. Unfortunately, no data are available that proves its potential to relieve mental illness. The current study is designed to assess neuro behavioral and antidepressant like effects of homeopathic remedies Staphysagria, Argentum nitricum and Ignatia amara in comparison with standard drug (escitalopram). Different neuro behavioral activities were analyzed. The animals were administered the doses of all homeopathic remedied (60 µl to the rats) and escitalopram (0.042 mg to rats) through the oral route. The activities were observed on day 30th and day 60th. Our result suggests that the swimming time in Staphysagria treated group were significantly improved (p<0.001) after day 60th and significance rise was observed (p<0.01) in Ignatia amara treated animals, whereas significant decline (p<0.05) in struggling time was observed in Argentum nitricum administered animals after the 60th day as compared to 30th day. The central square crossings were improved highly significantly (p<0.001) after the 30th day dosing, by all three remedies and peripheral squares crossing were found highly significantly increased (p<0.001) after chronic dosing in Staphysagria and Ignatia amara treated groups. It is concluded from the results that all three homeopathic remedies produce comparable effects like standard drug while among all three remedies Staphysagria possess a potent antidepressant activity. To the best of our knowledge the current study reports first time the anti-depressant potential of homeopathic remedies in rodents.

Identification of Novel Phyto-chemicals from Ocimum basilicum for the Treatment of Parkinson's Disease using In Silico Approach.

BACKGROUND: Parkinson's disease is characterized by decreased level of dopaminergic neurotransmitters and this decrease is due to the degradation of dopamine by protein Monoamine Oxidase B (MAO-B). In order to treat Parkinson's disease, MAO-B should be inhibited. OBJECTIVE: To find out the novel phytochemicals from plant Ocimum basilicum that can inhibit MAO-B by using the in silico methods. METHODS: The data of chemical constituents from plant Ocimum basilicum was collected and inhibitory activity of these phytochemicals was then predicted by using the Structure-Based (SB) and Ligand-Based Virtual Screening (LBVS) methods. Molecular docking, one of the common Structure-Based Virtual Screening method, has been used during this search. Traditionally, molecular docking is used to predict the orientation and binding affinity of the ligand within the active site of the protein. Molegro Virtual Docker (MVD) software has been used for this purpose. On the other hand, Random Forest Model, one of the LBVS method, has also been used to predict the activity of these chemical constituents of Ocimum basilicum against the MAO-B. RESULTS: During the docking studies, all the 108 compounds found in Ocimum basilicum were docked within the active site of MAO-B (PDB code: 4A79) out of which, 57 compounds successfully formed the hydrogen bond with tyr 435, a crucial amino acid for the biological activity of the enzyme. Rutin (-182.976 Kcal/mol), Luteolin (-163.171 Kcal/mol), Eriodictyol-7-O-glucoside (- 160.13 Kcal/mol), Rosmarinic acid (-133.484 Kcal/mol) and Isoquercitrin (-131.493 Kcal/mol) are among the top hits with the highest MolDock score along with hydrogen interaction with tyr 435. Using the RF model, ten compounds out of 108 chemical constituent of Ocimum basilicum were predicted to be active, Apigenin (1.0), Eriodictyol (1.0), Orientin (0.876), Kaempferol (0.8536), Luteolin (0.813953) and Rosmarinic-Acid (0.7738095) are predicted to be most active with the highest RF score. CONCLUSION: The comparison of the two screening methods show that the ten compounds that were predicted to be active by the RF model, are also found in top hits of docking studies with the highest score. The top hits obtained during this study are predicted to be the inhibitor of MAO-B, thus, could be used further for the development of drugs for the treatment of Parkinson's disease (PD).

Clinical and hospital pharmacy services are not just medical and pharmaceutical sciences but also occupy significant placement in healthcare system. Pakistan is a developing state with a huge prerequisite for changes in the general wellbeing framework, specially hospital and clinical aspect of pharmaceutical services. The principal intention of this study is to analyze the services offered by different pharmacies in hospitals of Karachi in terms of infrastructure and personnel service qualities. The study was conducted in a cross sectional way that included stratified sampling technique. Reactions were broken down utilizing descriptive and inferential insights of measurements. The fundamental result procedures incorporated the scope of hospital pharmacy services, the general recruitment of clinical drug specialists (pharmacist), the product and equipment used in hospital pharmacy services, the background of staff (educational), acquisition of proficient training mode, practical involvement and experience. The clinical pharmacy facilities coverage mutually on the departmental scale (median =22.43%) and patient scale (median =17.25%) do not comply the 100% coverage that is obligatory for standard practices. In addition, 48.65% of the pooled hospitals data has shown absence of distinct administration rules for hospital and clinical pharmacists, and 45.33% lacks the use of rational drug software. It is concluded that important parameters like drug monitoring, medication records keeping; appropriate drug information software's and quality assurance in hospitals still need attention for better patient outcomes.

A comparative neurobehavioral study of sesame oil and fish oil on experimental animals.

Natural oils are enriched with polyunsaturated fatty acids (PUFAs) which are important for our health. Recent experimental data explained that PUFAs might have a beneficial effect on various brain functions such as anxiety, dementia, epileptic seizures, depression or bipolar and other neurobehavioral diseases. The objective of the current research work was to evaluate the effect of sesame oil, fish oil and mixture of both oils (1:1) on neurobehavioral changes and cognition. For this purpose shark fish oil and sesame oil were extracted out and there poly unsaturated and saturated fatty acids were analyzed by using GCFID that exposed the presence of different PUFs in shark fish oil, sesame oil and mixture of both oils. Neurobehavioral changes were seen after 5ml/kg/day sesame oil, 5ml/kg/day shark fish oil and 1:1 combination of both oil 5ml/kg/day administration on open field, cage crossing, light and dark, stationary rod, forced swimming induced depression test and water maze test. Our GCFID results showed sesame and fish oil enriched with higher amount of PUFs and showed significant anxiolytic and antidepressant like effect after 30 days of treatment (P<0.05) however combination of these both oils exhibited greater efficacy (P<0.01) in reducing anxiety and depression as imipramine standard drug. Results showed that combination of both oils (sesame oil and fish oil) could be a better option to treat neurobehavioral problems as compared to alone.

Exploration of Carica papaya bioactive compounds as potential inhibitors of dengue NS2B, NS3 and NS5 protease.

Current outbreak of dengue has shown serious health concerns in Pakistan. The present study reports the anti-dengue potential of Carica papaya natural compounds. The leaves of C. papaya have previously shown promising results in cure of Dengue fever. The aim of this project is to find specific bioactive compounds by computational screening and biological activities of C. papaya against serine NS2B, NS3 and NS5 proteases of dengue virus. Docking study resulted in the screening of nine bioactive compounds having highest docking scores. However, three compounds namely epigallocatchin, catechin and protocatechuric acid had the strongest binding affinity with the active residues i.e., Ser135, His51 and Asp75 of dengue virus serine proteases. Results also indicated that the extract of C. papaya was a strong antimicrobial and antioxidant agent. It is concluded that the C. papaya compounds can be commercially applied for medical formulations against dengue virus.
