Ca-doped ZnO nanoparticles for MB dye degradation and adsorptive removal of tinidazole.

Industrial dye degradation involves several processes by which dyes are broken down, ideally into innocuous products. Methylene blue (MB) is one of the most commonly employed dyes in the textile industry and is released into water in routine industry processes. These discharges lead to creating a nocuous nature for humans and animals.

PERSPECTIVE: Semen additives for improving frozen-thawed buffalo and cattle semen - a review.

This comprehensive review delves into the evolving landscape of assisted reproductive technologies (ARTs) in bovine species, particularly focusing on the pivotal roles of semen additives in the cryopreservation of buffalo and cattle semen. In developing nations, where ARTs are still emerging, these techniques significantly influence bovine reproductive strategies. In contrast, developed regions have embraced them as primary approaches for dairy buffalo and cattle breeding.

Comparison of Real-time RT-PCR cycle threshold (Ct) values with clinical features and severity of COVID-19 disease among hospitalized patients in the first and second waves of COVID-19 pandemic in Chennai, India.

Introduction: Real-time reverse transcriptase-polymerase chain reaction (rRT-PCR) of nasopharyngeal/ oropharyngeal swab has been the gold standard test for detection of SARS-CoV-2 infection The relationship between cycle threshold (Ct) values of rRT-PCR and severity of disease remain disputable and not clearly defined in COVID-19.

Methodology: This is a single-centered retrospective observational study conducted at Government Corona Hospital (GCH), Guindy, Chennai. In the present study, we compared the Ct value of rRT-PCR from nasopharyngeal swab specimens with a diverse range of symptoms and disease severity among 240 individuals who were hospitalized with COVID-19, viz.

Genetic Characterization of Full-Length HIV-2 Long Terminal Repeat Sequences: Identification of Rare Promoter Variants.

In this study, we sequenced the full-length HIV type 2 (HIV-2) long terminal repeat region from the proviral DNA of 23 HIV-2-infected individuals from the southern parts of India. We identified two different promoter variant strains circulating in this region along with the globally circulating common promoter variant. Seven sequences had an additional nuclear factor kappa-light chain enhancer of activated B cells (NF-κB) binding motif and the sequence from another subject showed one NF-κB and one RBE-III binding site.
