The Ministry of New and Renewable Energy has published the R&D; Roadmap for Green Hydrogen Ecosystem in India. This document was published on 13th October, 2023. One of the central pillars of the National Green Hydrogen Mission is the establishment of a supportive research and innovation ecosystem for green hydrogen …

Potent antimalarial activity of Acriflavine In Vitro and In Vivo

Malaria continues to be a major health problem globally. There is an urgent need to find new antimalarials. Acriflavine (ACF) is known as an antibacterial agent and more recently as an anticancer agent. Here, we report that ACF inhibits the growth of asexual stages of both chloroquine (CQ) sensitive and …

Recent oral contraceptive use by formulation and breast cancer risk among women 20 to 49 years of age

Previous studies of oral contraceptives and breast cancer indicate that recent use slightly increases risk, but most studies relied on self-reported use and did not examine contemporary oral contraceptive formulations. This nested case–control study was among female enrollees in a large U.S. integrated health care delivery system. Cases were 1,102 …

PPARγ ablation sensitizes proopiomelanocortin neurons to leptin during high-fat feeding

Activation of central PPARγ promotes food intake and body weight gain; however, the identity of the neurons that express PPARγ and mediate the effect of this nuclear receptor on energy homeostasis is unknown. Here, we determined that selective ablation of PPARγ in murine proopiomelanocortin (POMC) neurons decreases peroxisome density, elevates …

Individual diet has sex-dependent effects on vertebrate gut microbiota

Vertebrates harbour diverse communities of symbiotic gut microbes. Host diet is known to alter microbiota composition, implying that dietary treatments might alleviate diseases arising from altered microbial composition (‘dysbiosis’). However, it remains unclear whether diet effects are general or depend on host genotype. Here we show that gut microbiota composition …

Pesticide Methoxychlor promotes the epigenetic transgenerational inheritance of adult-onset disease through the female germline

Environmental compounds including fungicides, plastics, pesticides, dioxin and hydrocarbons can promote the epigenetic transgenerational inheritance of adult-onset disease in future generation progeny following ancestral exposure during the critical period of fetal gonadal sex determination. This study examined the actions of the pesticide methoxychlor to promote the epigenetic transgenerational inheritance of …

The multiMiR R package and database: integration of microRNA–target interactions along with their disease and drug associations

microRNAs (miRNAs) regulate expression by promoting degradation or repressing translation of target transcripts. miRNA target sites have been catalogued in databases based on experimental validation and computational prediction using various algorithms. Several online resources provide collections of multiple databases but need to be imported into other software, such as R, …

Modifications to the Aesop's fable paradigm change new Caledonian Crow Performances

While humans are able to understand much about causality, it is unclear to what extent non-human animals can do the same. The Aesop's Fable paradigm requires an animal to drop stones into a water-filled tube to bring a floating food reward within reach. Rook, Eurasian jay, and New Caledonian crow …

Contact between bird species of different lifespans can promote the emergence of highly pathogenic avian influenza strains

The emergence of highly pathogenic avian influenza viruses has received much attention due to the severe consequences of their occasional spread to humans, as well as the large toll they take on the poultry industry. Here we argue that the main barriers to the emergence of these viruses are imposed …

PTEX component HSP101 mediates export of diverse malaria effectors into host erythrocytes

To mediate its survival and virulence, the malaria parasite Plasmodium falciparum exports hundreds of proteins into the host erythrocyte. To enter the host cell, exported proteins must cross the parasitophorous vacuolar membrane (PVM) within which the parasite resides, but the mechanism remains unclear. A putative Plasmodium translocon of exported proteins …

Inhaled corticosteroids in children with persistent asthma: effects on growth

Treatment guidelines for asthma recommend inhaled corticosteroids (ICS) as first-line therapy for children with persistent asthma. Although ICS treatment is generally considered safe in children, the potential systemic adverse effects related to regular use of these drugs have been and continue to be a matter of concern, especially the effects …

National happiness and genetic distance: A cautious exploration

This paper examines a famous puzzle in social science. Why do some nations report such high happiness? Denmark, for instance, regularly top the league table of rich nations' well being; Great Britain and the US enter further down; France and Italy do relatively poorly. Yet the explanation for this ranking …

Environmental safety of the use of major surfactant classes in North America

This paper brings together over 250 published and unpublished studies on the environmental properties, fate, and toxicity of the four major, high-volume surfactant classes and relevant feedstocks. The surfactants and feedstocks covered include alcohol sulfate or alcohol sulfate (AS), alcohol ethoxysulfate (AES), linear alkylbenzene sulfonate (LAS), alcohol ethoxylate (AE), and …

Strong contributions of local background climate to urban heat islands

The urban heat island (UHI), a common phenomenon in which surface temperatures are higher in urban areas than in surrounding rural areas, represents one of the most significant human-induced changes to Earth’s surface climate. Even though they are localized hotspots in the landscape, UHIs have a profound impact on the …

Sexually dimorphic effects of ancestral exposure to vinclozolin on stress reactivity in rats

How an individual responds to the environment depends upon both personal life history as well as inherited genetic and epigenetic factors from ancestors. Using a ‘two-hit, 3 generations apart’ model, we tested how F3 descendants of rats given in utero exposures to the environmental endocrine-disrupting chemical (EDC) vinclozolin reacted to …

Father's brain is sensitive to childcare experiences

Brain, oxytocin, and parenting behavior were measured in primary-caregiving mothers, secondary-caregiving fathers, and primary-caregiving homosexual fathers raising infants without maternal involvement. Parenting integrated functioning of two neural networks: subcortical-paralimbic structures implicated in emotional processing and cortical circuits involved in social understanding. Mothers showed greater activation in the emotional processing network …

Chronic impairment of bumblebee natural foraging behaviour induced by sublethal pesticide exposure

Insect pollination is a vital ecosystem service that maintains biodiversity and sustains agricultural crop yields. Social bees are essential insect pollinators, so it is concerning that their populations are in global decline. Although pesticide exposure has been implicated as a possible cause for bee declines, we currently have a limited …

Inhibition of Plasmepsin V activity demonstrates its essential role in protein export, PfEMP1 display, and survival of malaria parasites

The malaria parasite Plasmodium falciparum exports several hundred proteins into the infected erythrocyte that are involved in cellular remodeling and severe virulence. The export mechanism involves the Plasmodium export element (PEXEL), which is a cleavage site for the parasite protease, Plasmepsin V (PMV). The PMV gene is refractory to deletion, …

Effects of BMI, fat mass, and lean mass on asthma in childhood: A Mendelian Randomization Study

Observational studies have reported associations between body mass index (BMI) and asthma, but confounding and reverse causality remain plausible explanations. We aim to investigate evidence for a causal effect of BMI on asthma using a Mendelian randomization approach.

Time-varying, serotype-specific force of infection of dengue virus

Using mathematical models to extend knowledge of pathogen transmission and recommend optimized control efforts is dependent on the accuracy of model parameters. The rate at which susceptible individuals become infected [the force of infection (FoI)] is one of the most important parameters, but due to data constraints it is often …
