This study was conducted to validate the hepatoprotective activity of Cosmos sulphureus and Cosmos bipinnatus. Aqua-methanolic extracts of both plants were evaluated for the presence of various phyto-constituents through HPLC. Different doses of both plant extracts were administered to rats for nine days. Standard control was silymarin 100 mg/kg. Paracetamol 1 gm/kg was administered 3 h post treatment on 9th day for induction of hepatotoxicity. Blood was collected for the evaluation of liver biochemical markers and livers were removed for histopathological evaluation 24 h post-paracetamol treatment. HPLC analysis revealed the presence of quercetin, gallic acid, caffeic acid and chlorogenic acid in both plant extracts. The extracts of both plants decreased the level of alanine aminotransaminase and total bilirubin significantly (p < 0.05), dose dependently and protected hepatocytes from paracetamol-induced hepatotoxicity. It can be concluded that both plants may possess hepatoprotective activity possibly due to the presence of quercetin and phenolic compounds.

Epigenetic modifications, specifically acetylation of histone plays a decisive role in gene regulation and transcription of normal cellular mechanisms and pathological conditions. The bromodomain and extraterminal (BET) proteins (BRD2, BRD3, BRD4, and BRDT), being epigenetic readers, ligate to acetylated regions of histone and synchronize gene transcription. BET proteins are crucial for normal cellular processing as they control cell cycle progression, neurogenesis, differentiation, and maturation of erythroids and spermatogenesis, etc. Research-based evidence indicated that BET proteins (mainly BRD4) are associated with numeral pathological ailments, including cancer, inflammation, infections, renal diseases, and cardiac diseases. To counter the BET protein-related pathological conditions, there are some BET inhibitors developed and also under development. BET proteins are a topic of most research nowadays. This review, provides an ephemeral but comprehensive knowledge about BET proteins’ basic structure, biochemistry, physiological roles, and pathological conditions in which the role of BETs have been proven. This review also highlights the current and future approaches to pledge BET protein-related pathologies.

Gastro-esophageal reflux disease is a persistent affliction of gastrointestinal tract upper part with the growing prevalence throughout the world. By the time there has been an increase in the cognizance of its pathophysiology, clinical presentation and management. The disease could be identified easily by the symptoms. Many of the risk components are involved in the occurrence of disease including medications, obesity, pregnancy and asthma. It can be diagnosed by a number of procedures like manometry, ambulatory pH monitoring , endoscopy and radiology.Although different drugs are being utilized to treat GERD but PPIs (Proton pump inhibitors) have shown remarkable achievement in the curing the disease. When proton pump inhibitors are utilized for the extended period several of the safety ways are being explored to avoid any side effect. There has been a debate over the use of long term medications and surgery for quite a long time. Although both surgery and long term usage of PPI's have proven effective in managing the disease.
