As per a recent study conducted by the WHO, 15.4% of all cancers are caused by infectious agents of various categories, and more than 10% of them are attributed to viruses. The emergence of COVID-19 has once again diverted the scientific community’s attention toward viral diseases. Some researchers have postulated that SARS-CoV-2 will add its name to the growing list of oncogenic viruses in the long run. However, owing to the complexities in carcinogenesis of viral origin, researchers across the world are struggling to identify the common thread that runs across different oncogenic viruses. Classical pathways of viral oncogenesis have identified oncogenic mediators in oncogenic viruses, but these mediators have been reported to act on diverse cellular and multiple omics pathways. In addition to viral mediators of carcinogenesis, researchers have identified various host factors responsible for viral carcinogenesis. Henceforth owing to viral and host complexities in viral carcinogenesis, a singular mechanistic pathway remains yet to be established; hence there is an urgent need to integrate concepts from system biology, cancer microenvironment, evolutionary perspective, and thermodynamics to understand the role of viruses as drivers of cancer. In the present manuscript, we provide a holistic view of the pathogenic pathways involved in viral oncogenesis with special emphasis on alteration in the tumor microenvironment, genomic alteration, biological entropy, evolutionary selection, and host determinants involved in the pathogenesis of viral tumor genesis. These concepts can provide important insight into viral cancers, which can have an important implication for developing novel, effective, and personalized therapeutic options for treating viral cancers.
Aim:The objective of the present study was to find out the levels of analgesic drug meloxicam in the blood plasma of young goats. The drug was given to them through oral route. Data was used to elucidate the Pharmacokinetic determinants of the drug which were employed to arrive at the dose schedule and frequency of the drug in goats.
Materials and Methods:Elaborate pharmacokinetic research of the drug meloxicam was done on 18 to 24 months old, five adult male local goats (Capra hircus) of Assam weighing 20 to 25 kg.The drug was given orally at the dose rate of 0.35 mg/kg at the Goat Rearing farm, Guwahati, Assam. Analysis of blood was done by high performance liquid chromatography (HPLC) system.
Results:The mean values of area under curve (AUC) and mean area under curve (AUMC) were 3137.488 ± 125.3749 2 µg.min/ml and 4650460 ± 380892.4744 µg.min /ml respectively .The mean peak plasma level of meloxicam was 1.972 ± 0.0477 µg/ml at 600 min. The mean values of elimination half life (t ) and absorption half life (t ) were 693±0.00 min and
Conclusion:These pharmacokinetic determinants were used to determine the frequency and dose schedule of meloxicam in goats. The minimum effective concentration of the drug is 0.7 µg/ml in plasma. To maintain this, an initial loading dose of 0.5 mg/kg body weight should be followed by a maintenance dose of 0.4 mg/kg body weight/10 hour.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
