The investigation of excipient and additiveeffects on drug permeability is an intriguing use of this method. In this paper, the impact of epigallocatechin -3-gallate(EGCG), on the intestinal penetration of acetyl salicylic acid was investigated.

The study clearly showedthat the green tea extract enhances the absorption of Aspirin from goat intestine and this absorption enhancement activityof the plant is due to polyphenolic content, presence of polyphenols like catechins and epicatechins.","PeriodicalId":14906,"journal":{"name":"Journal of Advanced Scientific Research","volume":"89 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78395559","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}

Intracellular PPIX allows red fluorescence detection. In this study, 5-ALA fluorescent cytology using urine was compared with conventional cytology in the diagnosis of bladder tumors. In this prospective study, we compared the sensitivity and specificity between conventional cytology, 5-ALA fluorescent cytology and FDA approved commercially available kits (NMP-22 and BTA). The percentage of Protoporphyrin IX facilitated by 5-ALA was amplified in cancer urothelial cells compared to normal urothelial cells. The sensitivity of conventional cytology and 5-ALA fluorescent cytology was 64% and 96% respectively, whereas the specificity was 92% and 98.67% respectively. In conclusion, 5-ALA induced fluorescent urine cytology demonstrated promising outcomes in the detection of bladder carcinoma cells. Furthermore, low grade and low stage tumor cells as well as flat lesions were also positively and accurately interpreted using 5-ALA fluorescent cytology.","PeriodicalId":14906,"journal":{"name":"Journal of Advanced Scientific Research","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85349539","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}

Aceclofenac has poor water solubility, hence it corresponds to BCS class II drug. Poor solubility leads to poor oral bioavailability, so a challenge for drug delivery. The objective of the present research work is to improve solubility of aceclofenac by using a novel combination of anti-solvent and sono-precipitation technique. Sonoprecipitation has several advantages over conventional methods, like it is cost effective, produces small particle, process is clean, etc. To make this formulation, we dissolved aceclofenac in ethanol and applied 250W sonification for 5 sec followed by 5 sec of interval. This process was repeated for 12 mins and produced micro-sized Aceclofenac dispersion. Further, we characterized and evaluated Aceclofenac dispersion by X-ray powder diffraction (XRPD), Fourier transform infrared (FT-IR) spectroscopy, differential scanning calorimetric (DSC) and in vitro solubility and dissolution rate. The results shows that sonoprecipitation process led to the development of partially amorphous microparticles. The particle size range of 1-3 μm with mean diameter of 1.59 μm. The in-vitro studies indicated that the saturation solubility and dissolution rate of aceclofenac microcrystals were enhanced by 2.5 folds and 2-fold respectively, as compared to crude aceclofenac. In conclusion, the process of combining the antisolvent precipitation under sonication produced small, uniform, and stable aceclofenac microparticles with enhanced dissolution, solubility, and bioavaibility.","PeriodicalId":14906,"journal":{"name":"Journal of Advanced Scientific Research","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84142691","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}

This experiment is designed to develop an agro technique method for large scale production of geranium plantlets (cultivar CIM-Pawan) at field conditions using simple stem cutting method at North Indian field conditions in Uttar Pradesh, India.

This plant is commonly called Pride of India refers to the various parts of this plant, including the leaves, flowers, and seeds, which are used as folk medicine. It has been demonstrated that the phytochemical and anti-inflammatory activities are effective in the treatment of inflammatory conditions in traditional medicine. The qualitative phytochemical investigation of L. speciosa leaf, flower, and seed revealed that it contained steroids, terpenoids, glycosides, polyphenolic compounds, amino acids, saponins, alkaloids, flavonoids, reducing sugars, tannins, and many other active metabolites. Studies have shown active antiinflammatory ingredients in L. speciosa ethanolic extracts of leaf (LELE), flower (LEFE), and seed (LESE). The ethanolic extracts of L. speciosa (LELE, LEFE and LESE) were investigated for anti-inflammatory activity in carrageenan-induced paw edema in albino rats and compared to control and standard drug, Diclofenac injection. The experimental plant extracts were given orally at a concentration of 250 and 500 mg/kg b.w. before carrageenan injection. In the paw edema evaluation, the paw volume was measured in the early (from 0 min-3 h) and late (4-6 h) phases of edema formation. In acute inflammation paw models, the ethanol extracts significantly reduced paw edema. The result obtained is indicative that the ethanolic extract of leaf and seed with high dose of 500 mg/kg b.w. produced 42% of inhibition and is low as compared to the standard drug.

The use of plants and their extracts is one of the most valuable methods which are gaining concerns due to their imperative biological benefits. Plants are not only beautiful but majestic because they are rich sources of various medicinally important substances.

The beauty of the synthesis is: no involvement of any surfactant, catalyst or template. The aqueous silver ions are reduced to silver nanoparticles when exposed to plant extract.
