Klebsiella pneumoniae Glycoconjugate Vaccine Leads Based on Semi-Synthetic O1 and O2ac Antigens.

Klebsiella pneumoniae (KP) is a common opportunistic pathogen that emerged as a new critical threat to human health, due to its hypervirulence and widespread resistance against many antibiotics, including carbapenems. Alternative intervention strategies such as vaccines are not available.  Cell-surface lipopolysaccharides (LPS) and capsular polysaccharides (CPS) are attractive targets for vaccine development.

Epidemiological Profile and Outcome of COVID-19 Patients and Its Comparison Between the First and Second Wave at a Tertiary-Level COVID Care Facility in North India.

Background: In December 2019, COVID-19 emerged in China and spread rapidly throughout the world, including India. So far, India has witnessed three spells of the disease, termed the first, second, and third waves; although the first two waves were significant in terms of severity, mortality, and need for respiratory support, the third wave had no significant impact and most people recovered without being admitted to the hospital. The present study aimed to discuss the clinical demographic characteristics and in-hospital outcomes of COVID-19 patients and their comparisons between the first and second waves.

Time-Reversal Symmetry Breaking Superconductivity in HfRhGe: A Noncentrosymmetric Weyl Semimetal.

Weyl semimetals are a novel class of topological materials with unique electronic structures and distinct properties. HfRhGe stands out as a noncentrosymmetric Weyl semimetal with unconventional superconducting characteristics. Using muon-spin rotation and relaxation (µSR) spectroscopy and thermodynamic measurements, a fully gapped superconducting state is identified in HfRhGe that breaks time-reversal symmetry at the superconducting transition.

Millets for a sustainable future.

Our current agricultural system faces a perfect storm-climate change, burgeoning population, and unpredictable outbreaks like COVID-19 disrupt food production, particularly for vulnerable populations in developing countries. A paradigm shift in agriculture practices is needed to tackle these issues. One solution is the diversification of crop production.

Emerging contaminants in polluted waters: Harnessing Biochar's potential for effective treatment.

Biochar is a carbon-rich, sponge-like material with intricate functionalities, making it suitable for various environmental remediation applications, including water treatment, soil amendment and, additives in construction materials, anaerobic digesters, and electrodes, among others. Its easy adaptability and low cost make it particularly attractive. This review highlights a range of biochar and surface-modified biochar exhibiting high uptake and degradation efficiencies for a broad spectrum of contaminants, including humic acid, disinfection by-products (DBPs), radioactive materials, dyes, heavy metals, antibiotics, microplastics, pathogens, Per- and polyfluoroalkyl substances (PFAS), and cytotoxins.
