Comparison of Basal Core Promoter Region Mutation and Precore Mutation among Monoinfected Hepatitis B Virus and Coinfected Hepatitis B Virus with Human Immunodeficiency Virus Patients.

Objectives: Hepatitis B virus (HBV) has a partially double-stranded circular deoxyribonucleic acid (DNA) that replicates through reverse transcription, producing an intermediate ribonucleic acid (RNA). This replication process has a high chance of error, leading to several mutations in the genome. According to several studies conducted worldwide, the classical basal core promoter (BCP) double mutation (A to T at nucleotide 1762 and G to A at nucleotide 1764) in the BCP region and the mutation in the precore (PC) region (G to A at nucleotide 1896) of HBV DNA have a strong correlation with advanced liver disease.

Comparative microbial community occurrence pattern, growth attributes, and digestive enzyme indices of Puntius gonionotus (Bleeker, 1850), Pangasianodon hypophthalmus (Sauvage, 1878) and Heteropneustus fossilis (Bloch, 1794) under freshwater biofloc based polyculture system.

Background: The biofloc system (BFS) provides a sustainable aquaculture system through its efficient in situ water quality maintenance by the microbial biomass, besides continuous availability of these protein-rich microbes as feed to enhance growth and immunity of the reared organism. This study explores the gill architecture, growth performance, digestive enzyme activity, intestinal microbial composition, and histology of three freshwater fish species, Puntius gonionotus, Pangasianodon hypophthalmus, and Heteropneustus fossilis reared in biofloc based polyculture system.

Results: The three species in T2 showed significantly higher WG and SGR, followed by T1 and T3.

Integrating computational methods and experimental validation reveals the pharmacological mechanism of (L.) Baker targeting major proteins in breast cancer.

Breast cancer remains a significant global health challenge, necessitating the exploration of novel therapeutic options. The present study employs an integrated approach encompassing network pharmacology, molecular docking, molecular dynamics simulations, and validation to investigate the potential of in breast cancer treatment. Initial network pharmacology analysis revealed different potential targets and pathways associated with breast cancer that could be modulated by phytochemical constituents.

MicroRNA-21 (miR-21) in breast cancer: From apoptosis dysregulation to therapeutic opportunities.

Breast cancer, a pervasive and complex disease, continues to pose significant challenges in the field of oncology. Its heterogeneous nature and diverse molecular profiles necessitate a nuanced understanding of the underlying mechanisms driving tumorigenesis and progression. MicroRNA-21 (miR-21) has emerged as a crucial player in breast cancer development and progression by modulating apoptosis, a programmed cell death mechanism that eliminates aberrant cells.

Targeting the autophagy-miRNA axis in prostate cancer: toward novel diagnostic and therapeutic strategies.

Since prostate cancer is one of the leading causes of cancer-related death, a better understanding of the molecular pathways guiding its development is imperative. A key factor in prostate cancer is autophagy, a cellular mechanism that affects both cell survival and death. Autophagy is essential in maintaining cellular homeostasis.
