Sixteen adult female wistar rats were randomly divided into four groups with four rats in each group (A, B, C and D). Group A, the control group received distilled water. Groups B, C and D received 1mg/kg, 2mg/kg and 3mg/kg of Flunitrazepam (Rohypnol) respectively. The animals were sacrificed after three weeks of administration and the cerebral cortexes were harvested and fixed in 10% formal saline for histological processing and studies. The anthropometric investigation presented an insignificant increase in the relative body weight of the test groups when compared to the control group and also presented a significant increase in the relative organ weight in the entire test groups when compared to the control group. The cerebral cortex of experimental animals showed; severe lymphocytic infiltration, focal areas of liquefactive necrosis, intracerebral hemorrhage, vacuolation and various degrees of damages to the tissue layers and neuronal cells of the cerebral cortex. This scientific investigation indicates that consumption of Flunitrazepam (Rohypnol) across various graded doses causes changes in the cerebral cortex histoarchitecture which explains the rationale behind the loss of cerebral cortex function in drug addicts and patients placed on prolonged Flunitrazepam (Rohypnol) therapy.","PeriodicalId":7378,"journal":{"name":"Advances in Pharmacology and Pharmacy","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84667358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It arises from the endometrium and accompanied by the abnormal growth of the cells. Sign and symptoms include pelvic pain and abnormal vaginal bleeding. It has two categories. Type 1 tumors are estrogen-dependent and they have mutations in PTEN, PIK3CA while Type 2 tumors are more sensitive and have mutations in TP53. Overactivation of the signaling pathway (PI3K) results in anti-apoptosis. Here, this study aims to identify Tumor-Specific Antigen for germline mutations in endometrial cancer which can be used as a potential vaccine candidate. The germline mutations data are obtained from cancer gene census of the cosmic database. Genes mutating with crucial role in endometrial cancer are considered. Peptides libraries are generated using peptide design library. Human leukocyte antigen alleles are identified for the peptide library through NetMHC. Binding affinities of alleles with peptide are determined. Linear regression is performed to generate graphs. PTEN, TP53, PIK3CA, KRAS, and CTNNB1 proved to have critical role. About 575 overlapping peptide libraries are generated and each peptide has a length of 18-20 amino acids. Approximately 58 HLAs are identified, having strong interactions with HLAs. Regression analysis shows that the no. of mutations are directly associated with a binding affinity of peptides. From this, we suggest that the identified TSA can be used as personalized peptide vaccines that directly target the mutated genes in endometrial cancer. This research work can be used in the laboratories for further validation.","PeriodicalId":7378,"journal":{"name":"Advances in Pharmacology and Pharmacy","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72953442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PI3Ks establish a lipid kinase family that is important to integrate disparate dimensions of cell functions including cell survival, vesicular trafficking, proliferation, and cell migration. This is an essential pathway in the oncogenesis and advancement of lung cancer. In preclinical studies, PIK3 inhibitors deliver exploratory antitumor activity. The study was established to realize perception and molecular mechanisms that are crucial for potent inhibitors of PIK3CA. In this research work, mutated proteins of PIK3CA were selected, models of pharmacophore were designed and hit compounds were obtained against reference feature pharmacophore by virtual screening. These hit compounds were then docked with the mutated proteins of PIK3CA. Three important features were shown by Pharmacophores, Hydrogen bond donor (HBD), Hydrogen bond acceptors (HBA) and aromatic rings (AR). Through virtual screening, 8 hit compounds were obtained before docking Lipinski rule of five was applied and the compounds that achieved all properties were docked with mutated proteins of PIK3CA. 3 compounds fulfilled all properties and demonstrated the stability of ligands. It is suggested that these compounds can be used for curing PIK3CA involved in lung cancer and on the basis of shared feature novel compounds can be designed against a mutation in PIK3CA involved in lung cancer.","PeriodicalId":7378,"journal":{"name":"Advances in Pharmacology and Pharmacy","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74574361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Morphine has been used extensively in pain management but there is no consensus about the effectiveness of method of administration. The aim of this study was to compare the divided dose vs bolus medication form of morphine sulfate for management of acute pain in traumatic fracture. Methods: we designed a randomized double-blind clinical trial. On basis of inclusion and exclusion criteria, 160 patients with acute traumatic fracture were enrolled to the study and randomly divided into two groups. The first group (bolus group) received 0.1mg/kg morphine and then 0.1mg/kg normal saline every 5 minutes. The second group (titration group) received 0.1mg/kg of morphine in divided doses every 5 minutes. All injections were intravenously. The primary outcome was pain and before of injection, 15 minutes and 60 minutes after injection were recorded. Data were analyzed using SPSS 19. Results: 77 patients included 49 (63.6%) male with mean age of 47.42 ± 13.15 years were in titration group and 83 patients included 47 males (56.6%) with mean age of 52.40 ± 15.62 years were in bolus group. The complication rate was significantly higher in bolus group (75.9% vs 53.2%, P <0.0001). The need to extra morphine injection in bolus and titration group were 62.7% and 28.6%, respectively (P <0.0001). The mean pain score before and at 15 and 60 minutes after injection were 9.56 ± 1.03, 6.61 ± 1.86 and 1.85 ± 1.13 in titration group and 9.76 ± 0.48, 6.53 ± 1.59 and 0.61 ± 0.46 in bolus group, respectively. The pain score was significantly lower in titration group at 60 minutes after injection (P <0.0001).

More of the boreholes contained Candida albicans than the other isolates during both seasons. Candida albicans occurred most frequently in the water samples during both seasons while Fonsecaea pedrosoi had the lowest frequency of occurrence in the water samples during both seasons. All the isolates were resistant to Griseofulvin while they exhibited varying degree of resistance and sensitivity to the other antifungal agents used. This study indicated that the borehole water samples examined did not comply with the standard established by regulatory bodies for potable water and therefore must be adequately treated before drinking and use for domestic purposes as these fungi have been reported to cause diseases of humans and animals.

The growing incidence of diabetes mellitus and its complications have headed to the search of novel therapeutic approaches engrossed on preventing postprandial hyperglycemia. The practice of carbohydrate breakdown enzyme inhibitors from plant resources might be a potential approach to prevent glucose absorption with the least adverse effects. Aims: The objective of the present investigation was to provide in-vitro evidence for the potential inhibitory activity of polyphenolic extract (PPE) of Ichnocarpus frutescens on amylase and glucosidase enzymes. Methods: the in the vitro inhibitory effect of polyphenolic extract (PPE) of Ichnocarpus frutescens focused on the evaluation of pancreatic amylase inhibition, rat serum amylase inhibition and rat intestinal glucosidase inhibition of polyphenolic extract (PPE) of Ichnocarpus frutescens by in vitro. The different concentrations of polyphenolic extract were subjected to amylase and glucosidase inhibitory assay and the percentage of amylase and glucosidase inhibitory activity and IC50 values were calculated. Results: Polyphenolic extract shows appreciable pancreatic amylase inhibitory activity in vitro. The extract also showed an appreciable glucosidase inhibitory effect in a concentration-dependent manner with a moderate amylase inhibitory activity. The in vitro examination of the inhibitory effect of PPE on maltase and sucrase activities revealed that PPE inhibited rat small intestine disaccharidase ( glucosidase) activity. Conclusion: Taken together, these results suggest that inhibitory effect of PPE on amylase and glucosidase activities may delay carbohydrate digestion and absorption with subsequent lowering of blood glucose level leading to prevention of postprandial hyperglycemia in diabetes and its complication.","PeriodicalId":7378,"journal":{"name":"Advances in Pharmacology and Pharmacy","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83865508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
