Effect of 11β-hydroxyandrostenedione (OHA) on the gonadal differentiation in whitefish Coregonus lavaretus L.

Frontiers in Marine Science, 2015
Monosex stocks of fish become increasingly important in the aquaculture. In fish with male heterogamety, mating females with neo-males i.e. hormonally sex reversed (masculinized) females results in “all-female” stocks.

Preserved Spermatogenesis and Hormonal Function in Men Receiving a Pretomanid Regimen (BPaMZ) for Pulmonary Drug‐Resistant Tuberculosis

Clinical Pharmacology &Therapeutics, EarlyView.
Pretomanid is a component of the World Health Organization‐recommended treatment regimen for drug‐resistant tuberculosis in patients aged ≥ 14 years. While preclinical rodent studies identified testicular toxicity as a potential clinical liability at elevated doses, no corresponding effects were observed in nonhuman primates nor clinical hormone ...

Entropy‐Driven Innovations: Entropy Stabilized Oxides for High‐Performance Next‐Generation Lithium–Sulfur Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This article explores high‐entropy‐stabilized oxides (HEOs) as novel functional materials for addressing critical issues in lithium–sulfur (Li–S) batteries, including lithium polysulfide (LPS) shuttling, inadequate conductivity, and slow redox kinetics.

Commonalities of platelet dysfunction in heart failure with preserved ejection fraction and underlying comorbidities

ESC Heart Failure, Volume 12, Issue 2, Page 1013-1028, April 2025.
Abstract Heart failure with preserved ejection fraction (HFpEF) is characterized by a lack of a specific targeted treatment and a complex, partially unexplored pathophysiology. Common comorbidities associated with HFpEF are hypertension, atrial fibrillation, obesity and diabetes.

Genotypic correlations of morpho-agronomic traits in papaya and implications for genetic breeding

Crop Breeding and Applied Biotechnology, 2007
It is essential to study the correlations between traits of genetic breeding, principally, when selection for a trait is impaired by low heritability or difficulties with measurement and identification. This study aimed to estimate genotypic correlations

Effect of Austerity Measures on Infant Mortality: Evidence From Greece

Health Economics, EarlyView.
ABSTRACT Governments frequently adopt austerity policies when facing economic crises, yet their long‐term consequences for population health remain incompletely understood. This paper examines the impact of large‐scale fiscal austerity on infant mortality by exploiting the Troika‐led economic adjustment program implemented in Greece beginning in 2010 ...

Masculinización de tilapia roja (Oreochromis spp) por inmersión utilizando 17 alfa–metiltestosterona Red tilapia (Oreochromis spp) masculinization by immersion using 17 alpha-methyltestosterone

Revista Colombiana de Ciencias Pecuarias, 2007
La tilapia roja (Oreochromis spp) es ampliamente producida a nivel mundial. Un inconveniente para su producción es la alta precocidad para la reproducción, lo que afecta su crecimiento y ocasiona la superpoblación.

Dynamic miRNA landscapes unlock sexual plasticity in protogynous orange-spotted grouper under MT-implantation

Aquaculture Reports
Sex change, a manifestation of sexual plasticity, is widespread among fish, yet its molecular regulatory mechanisms, particularly those involving miRNAs, remain largely unresolved.
