Objective: This dissertation work aimed to prepare Levocetirizine HCL (LCH) nasal in-situ gel, a second-generation antihistamine, to improve its retention time, sustain release, enhance the bioavailability, and avoid first-pass metabolism. Process: The in-situ nasal gel was prepared to consume Carbopol as a gelling agent, Hypromellose (HPMC) as a thickening or thickness-imparting agent, and buffering agents to maintain pH. An assessment was conducted to determine the solubility, pH, rheological characteristics, consistency of content, adhesive properties to mucous membranes, gel strength, in-vitro release characteristics, the kinetics of release date, isotonicity, and sterility of the sample. Results: All formulations had a clear appearance with good gelling capacity, and drug content was found to be >87%. The pH values of the formulations were found to be acceptable, ranging from 6.2 ± 0.10 to 6.4 ± 0.44, and no irritation of the mucosal membranes was observed. The shearing character was found between 200-1400 at pH 6.4 and 2000-5500 cps at pH 7.4 when measured at 20 rpm. They also showed adequate gel strength of...

The rising burden of cancer worldwide calls for an indispensable treatment result. Herbal drug provides a veritably doable volition to western drug against cancer. This composition reviews the named plant species with active phytochemicals, the animal models used for these studies, and their nonsupervisory aspects. This study is grounded on a scrupulous literature review conducted through the hunt of applicable keywords in databases, Web of Science, Scopus, PubMed, and Google Scholar. Twenty shops were named grounded on defined selection criteria for their potent anticancer composites. The detailed analysis of the exploration studies revealed that plants play a necessary part in fighting different cancers similar as bone, stomach, oral, colon, lung, hepatic, cervical, and blood cancer cell lines. The in-vitro studies showed cancer cell inhibition through DNA damage and activation of apoptosis- converting enzymes by the secondary metabolites in the plant excerpts. Studies that reported in-vivo conditioning of these plants showed remarkable results in the inhibition of cancer in animal models. Further studies should be performed on exploring further plants,...

Optimizing the cultural conditions to enhance bioactive metabolite production by Streptomyces rubrus VLK-24 isolated from mangrove sediments as well as characterizing these compounds, has been taken up in this study. The culture broth inoculated in Yeast extract, Malt extract, and Dextrose broth and extracted with ethyl acetate exhibited high antimicrobial activity against test microorganisms, including Gram-negative and Gram-positive bacteria as well as fungi. The crude ethyl acetate extract exhibiting high antimicrobial activity was analyzed by Gas Chromatography-Mass Spectroscopy, which evidenced the presence of 39 compounds according to the available library data, NIST MS Search (ver. 2.0). The results of the study revealed the production of diversified metabolites by the strain; hence it could be a possible source for novel antimicrobial...

COVID-19, caused by Severe Acute Respiratory Syndrome CoV-2 (SARS CoV-2), has become a global burden. The naïve era of infection prompted early dependence on case reports of insufficient data and conceptual elucidation to explain and anticipate the effect on cardiovascular diseases. Many COVID-19-infected and vaccinated individuals have reported an increased incidence of cardiovascular disorders, leading to higher morbidity and mortality rates. Sometimes COVID can also manifest as a severe coronary artery disease or myocarditis in those with no background in cardiovascular diseases or those with cardiovascular risk factors, which are often misunderstood as a primary cardiovascular disorder. COVID-induced cardiovascular complications like DVT, VTE, MI, and long COVID have been the crux of the matter. To combat the SARS-CoV-2 disease, several countries took the lead in developing COVID-19 vaccines, but only a few were effective against coronavirus, which created a ray of hope in curbing COVID-19 disease. As the thumb rule says, any substance that is foreign to the body, including vaccines, has flaws seen in the forms of adverse...

For the present study, 10 bacterial strains were isolated from agriculture field soils collected from Guntur, Andhra Pradesh, India, and thereafter screened for amylase activity. Among them, the strain DS5 showed a maximum zone of clearance on the starch hydrolysis test was selected for this study. Identification of bacterial strain DS5 was confirmed by 16S rRNA sequencing analysis. The phylogenetic tree constructed on the basis of 16S rRNA sequences revealed that it clustered with the closest members of Bacillus pumilus DS5 and the sequences were deposited in NCBI Gen bank along with accession number MK430437. Further the effect of incubation period, temperature, pH, carbon and nitrogen sources was optimized. Highest amylase production was found after 48 h of incubation at pH 7.0 and 40 ⁰C temperature. Starch proved to be the best carbon source and peptone as nitrogen source for the highest production of amylase by Bacillus pumilus DS5. Supplementation with different nitrogen and carbon source favoured the increased enzyme yield by submerged...
