Hexane, chloroform, ethyl acetate and methanol extracts from the leaves of Acalypha indica were tested against Gram-positive (Staphylococcus aureus, Staphylococcus epidermidis, Bacillus cereus, Streptococcus faecalis) and Gram-negative (Klebsiella pneumoniae, Escherichia coli, Proteus vulgaris, Pseudomonas aeruginosa) bacteria. All the extracts exhibited antibacterial activity against Gram-positive organisms with minimum inhibitory concentrations (MIC) between 0.156 to 2.5 mg/ml. Among the Gram-negative bacteria, only the Pseudomonas aeruginosa was susceptible to the extracts.

In this study, we have designed and developed a cationic bolaform C12-(2,3-dihydroxy-N, N-dimethyl-N-(2-ureidoethyl)propan-1-aminium chloride)2 (C12(DDUPAC)2) that is derived from biocompatible molecules. The bolaform C12(DDUPAC)2 has hydroxyl (OH) functionality at both the cationic head groups. The impact of head group structure on the self-assembly and effectiveness of gene transfection and antimicrobial activity was investigated and compared with that of the hydrochloride salt C12-(N, N-dimethyl-N-(2-ureidoethan-1-aminium chloride)2 (C12(DUAC)2) of its precursor molecule.

Phages demonstrate remarkable promise as antimicrobial agents against antibiotic-resistant bacteria. However, the emergence of phage-resistant strains poses challenges to their effective application. In this paper, we presented the isolation of a phage adaptive mutant that demonstrated enhanced and sustained antibacterial efficacy through the co-evolution of () 111-2 and phage ZX1Δint .

Objective: Colorectal Cancer (CRC) has attracted much attention due to its high mortality and morbidity. Cordycepin, also known as 3'-deoxyadenosine (3'-dA), exhibits many biological functions, including antibacterial, anti-inflammatory, antiviral, anti-tumor, and immunomodulatory effects. It has been proven to show anticancer activity in both laboratory research studies and living organisms.

Crystal Violet (CV) is a vibrant and harmful dye known for its toxicity to aquatic life and potential carcinogenic effects on humans. This study explores the removal of CV through photocatalysis driven by visible light, as well as examining the antibacterial and antibiofilm characteristics of zinc oxide nanoparticles (ZnO NPs) synthesized from the aerial roots of Ficus benghalensis. Various characterization techniques were employed to confirm the optical properties, crystal lattices, and morphology of ZnO NPs.
