The objective behind this study is to investigate the affinity between a carboxylic model drug telmisartan and kaolin. Telmisartan was comilled in solid state with kaolin in different weight ratios and characterized by Fourier transform infrared spectroscopy, Differential scanning calorimetry, X-ray powder diffractometry, scanning electron microscopy to examine the extent of transformation from crystalline to amorphous state. XRD and SEM studies revealed complete amorphization of telmisartan on comilling with kaolin for 1 h at 1:2 ratio. FTIR study showed that on milling with kaolin, the free acid carbonyl peak of telmisartan at 1692.14 cm-1 was disappeared, and a new carboxylate peak at 1578.72 cm-1 appeared. This disappearance of acid carbonyl peak and appearance of new carboxylate peak indicating an acid-base reaction between the carboxylic acid of telmisartan and kaolin. DSC study stated that in the milled samples, the melting endotherm of telmisartan was gradually shifted to lower temperature, and the intensity, as well as sharpness of the endotherm, was decreased. In-vitro study showed greater dissolution of telmisartan from telmisartan-kaolin...

Areca catechu L. (Arecaceae) is a species of palm mainly grown in Asian countries for seed crop. Areca nut leaves are commonly used in traditional systems of medicine against various ailments. There is a need for identifying native natural plant sources to acquire their recognized medicinal properties, which may widen them to use as new therapeutics for various diseases. Phytochemical investigation of the leaves of Areca catechu L. yielded a alkaloid- Arecoline, from the chloroform extract; a flavonoid- Apigenin, from the methanol extract and a steroid- Stigmasterol, from petroleum ether extract. In-vitro methods were used to evaluate the pharmacological activity of the leaves of Areca catechu L. Anti-inflammatory activity of the leaves of Areca catechu was estimated by using standard methods like protein denaturation method using bovine serum albumin fraction and egg albumin and by HRBC membrane stabilization method. The result suggests that the leaves possess good antioxidant as well as anti-inflammatory...

Purpose of the study: To assess Structural and functional abnormalities associated with High fructose diet-induced Metabolic syndrome in wistar albino rats. Materials and Methods: Metabolic syndrome is induced in adult male Wistar albino rats by feeding a combination of High Fructose Diet (55%) and Fructose enriched water (15%) for 75 days and kept as group 2 or HFrD Group. Normal male Wistar albino rats were kept as Normal control. During the entire course of study, weekly weight gain was monitored once a week in both groups. Biochemical investigations such as lipid profile, liver function test, and renal function test was carried out using standard methods. Routine histological studies were done to analyze the microstructural changes. The obtained data were statistically analyzed by students‘t’ tests and the values were considered statistically significant at p<0.05. Results: Chronic administration of a High fructose diet (HFrD) resulted in obesity, abnormal hepatic and renal functions in wistar rats. The gross and microstructural changes were minimal in the pancreas and heart, whereas significant damages were...

Five marine sponges were collected off Carmen, Agusan del Norte, Philippines and taxonomically identified as Axinyssa sp., Plocamionida sp., Forcepia sp., Pachymatisma sp and Placospongia sp. The “non-polar” (EtOAc-MeOH) and “pola”r (EtOH-H2O) extracts of the marine sponges were prepared and subjected to 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, a total antioxidant capacity assay using the phosphor molybdenum method and antimicrobial assay using the paper disc diffusion method. The marine sponge extracts exhibited low antioxidant activity as indicated by both the percent antiradical activity values obtained which ranged from 0.89% to 5.41% and the total antioxidant capacity values expressed as Ascorbic Acid Equivalence (AAE) ranging from 11.99 to 126.67 AAE and Butylated Hydroxytoluene Equivalence (BHTE) with a value range of 6.64 to 148.30 BHTE). The non-polar extracts from all the marine sponges as well as the polar extract from the marine sponge Forcepia sp. showed antibacterial activity against the two bacterial strains, B. subtilis and E. coli. However, the marine sponge extracts no significant antifungal activity against the two fungal...

The noble coronavirus SARS-CoV-2 results in a devastating, multisystem disease among which COVID-19 pneumonia creates serious complications and most of COVID-19 related deaths. COVID-19 patients develop a systemic inflammatory response through interleukin (IL) and tumor necrosis factors. In COVID-19 patients, cytokine storm controlling is the key step for treatment because cytokine attacks own body cells instead of fighting with the virus. We reviewed several literatures to summarize the safety and efficacy of LD-RT in COVID-19 patients. Low dose chest radiation may reduce the inflammation in the lungs in severely ill patients. The radiation offset an immune system called AS a cytokine storm. Several randomized/non-randomized, single/multi-centered, open/close clinical trials are underway in U.S, India, Iran and around the globe. Early studies showed LD-RT reduces the inflammatory cytokines, time of hospitalization, duration of ventilation, and a number of deaths. However, some researchers warned for radiation-induced cancer (lung, breast, and esophageal) and cardiovascular diseases. So, further extensive preclinical studies should be conducted to identify the risk-benefit ratio in COVID-19...
