A Chromosome Inversion Creates a Supergene for Sex and Colour in Lake Malawi Cichlids

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Cichlid fishes have the highest rates of evolutionary turnover of sex chromosomes among vertebrates. Many large structural polymorphisms in the radiation of cichlids in Lake Malawi are associated with sex chromosomes and may also carry adaptive variation.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Plasticity of the heart in response to changes in physical activity

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The heart adapts to changes in physical activity, with inactivity (e.g. bed rest or spaceflight) causing cardiac atrophy and ventricular stiffening, and endurance exercise training leading to eccentric hypertrophy and improved ventricular compliance.

Role of gas in supporting grand spiral structure [PDF]

open access: yes, 2015
The density wave theory for the grand-design two-armed spiral pattern in galaxies is successful in explaining several observed features. However, the long-term persistence of this spiral structure is a serious problem since the group transport would ...

In Vitro Validation of Pulsed Electromagnetic Field (PEMF) as an Effective Countermeasure Against Inflammatory‐Mediated Intervertebral Disc Degeneration

open access: yesJOR SPINE, Volume 8, Issue 2, June 2025.
ABSTRACT Background Intervertebral disc (IVD) degeneration (IDD) is the main contributor to chronic low back pain (LBP), the leading cause of disability worldwide, with a significant impact on the quality of life and health of common people. The etiology of IDD is still unclear, but it has been largely demonstrated the crucial role of inflammation and ...

Plant‐Based Mycetoma Inhibitors Targeting the 50S Ribosomal Protein of Nocardia brasiliensis: In Silico Approach

open access: yesChemistrySelect, Volume 10, Issue 21, June 4, 2025.
In‐silico drug discovery pipeline for Mycetoma caused by Nocardia brasiliensis. A library of 1034 phytocompounds was screened to identify potent inhibitors, with Parviflorone F showing strong binding and stability against the 50S ribosomal unit. Molecular dynamics confirmed its inhibitory potential, offering a promising therapeutic candidate.
