Wetlands function as carbon sink: Evaluation of few floodplains of middle Assam, northeast India in the perspective of climate change.

Floodplain wetlands are biologically rich and productive ecosystems that can capture carbon (C) from the atmosphere through macrophytes and phytoplanktons and hold it in soil for a long time thus playing a critical role in mitigating climate change. The Assam state of India has about 1392 floodplain wetlands engulfing around 100,000 ha area in the Brahmaputra and Barak River basin. In the present study, five different wetlands in the middle Assam viz.

Isolation and characterization of Saprolegnia parasitica from cage-reared Pangasianodon hypophthalmus and its sensitivity to different antifungal compounds.

Saprolegniasis is one of the most dangerous fungal diseases of fish, causing significant mortality in fish hatcheries and young ones. The present study aimed to isolate and characterize the causative fungus from fingerlings of Pangasianodon hypophthalmus cultured intensively in freshwater cages in Indian reservoirs and to determine minimum inhibitory concentrations of different antifungal compounds against the fungal hyphae and zoospores. The fungal isolates grown on potato dextrose agar showed an abundance of gemmae, elongated mycelia, non-septate hyphae, primary zoospores, mature zoosporangia with numerous zoospores, cysts with bundles of long hairs and were further identified as Saprolegnia parasitica following PCR amplification and sequencing of internal transcribed spacer region.

Microtubule-Targeting NAP Peptide-Ru(II)-polypyridyl Conjugate As a Bimodal Therapeutic Agent for Triple Negative Breast Carcinoma.

Triple-negative breast cancer (TNBC) poses significant treatment challenges due to its high metastasis, heterogeneity, and poor biomarker expression. The N-terminus of an octapeptide NAPVSIPQ () was covalently coupled to a carboxylic acid derivative of Ru(2,2'-bipy) () to synthesize an N-stapled short peptide-Rubpy conjugate (). This photosensitizer (PS) was utilized to treat TNBC through microtubule (MT) targeted chemotherapy and photodynamic therapy (PDT).

Where do the pyrene molecules reside within the surface active ionic liquid micelles in presence of sodium alginate?

Pyrene fluorescence in aqueous solutions of two surface active ionic liquids, namely, 1-decyl-3-methylimidazolium chloride, and 1-hexadecyl-3-methylimidazolium chloride was investigated in presence of a biopolymer sodium alginate. The principal objective of this study was to explore the influence of the length of the hydrocarbon tails of these surface active ionic liquids on the possible location of the probe (pyrene) molecules in presence of the additive. While an abrupt decrease in the values of the ratio of the intensity of the first vibronic band to that of the third band of pyrene emission spectrum with concentration was observed for 1-hexadecyl-3-methylimidazolium chloride in presence of sodium alginate like the polymer-free case reported earlier, there was a peculiar reversal for 1-decyl-3-methylimidazolium chloride + sodium alginate.

Trace metal accumulations in commercially important fish and crab species from impacted tropical estuary, India: implications on human health risk assessment.

Despite the beneficial role of aquatic food, bioaccumulation of trace metals can increase health risk for consumers. We conducted a comprehensive study to understand the levels of various trace metals (Cd, Co, Cr, Cu, Fe, Ni, Pb, Zn and Mn) in fish (Nematalosa nasus, Gerres filamentosus, Arius arius, Gerres erythrourus, Sardinella fimbriata, Caranx ignobilis, Etroplus suratensis, Mugil cephalus, Sillago sihama, and Euryglossa orientalis) and crab (Portunus pelagicus and Scylla serrata) species collected from Netravathi-Gurupur estuary, India and evaluated the potential health risks to humans by measuring target health hazard (THQ), hazard index (HI), estimated daily (EDI) and weekly (EWI) intake and cancer risk (CR). The hierarchy of toxic metal content in studied species was Fe>Pb>Cr>Mn>Zn>Cu>Ni>Cd>Co.
