Assessment of the effect of 21-day head-down bed rest on the cardiovascular system by blood protein composition

open access: yesFrontiers in Physiology
Head-down bed rest (HDBR) is one of the models of the physiological effects of weightlessness used, among other things, to assess the effect of hypokinesia on the physiological systems of the human body and, first of all, on the cardiovascular system ...

Platelet‐Rich Fibrins as Local Drug‐Delivery Carriers

open access: yesJournal of Periodontal Research, EarlyView.
Autologous platelet concentrates (APCs), particularly platelet‐rich fibrin (PRF), act as biologically active fibrin scaffolds, capable of entrapping and gradually releasing therapeutic agents in oral and periodontal therapy. The incorporation of bioactive compounds, such as antibiotics, antifungals, vitamins, antidiabetic drugs, and exosomes, enhances ...

Photodegradation of commercial insect repellents containing DEET and IR‐3535 under ultraviolet light associated or not with chemical ultraviolet filters evaluated by Raman spectroscopy

open access: yesPhotochemistry and Photobiology, EarlyView.
This study evaluated the photodegradation of commercial insect repellents containing DEET and IR‐3535 under UV‐A and UV‐B irradiation using Raman spectroscopy. Pure DEET and IR‐3535 showed intrinsic photostability, whereas DEET diluted in ethanol and a commercial DEET‐based formulation exhibited significant spectral changes after UV exposure.

Last Tile Added to a Mosaic: Phylogenetic Placement of Enigmatic Freshwater Fish Leucalburnus satunini (Cypriniformes: Leuciscidae) Uncovered

open access: yesZoologica Scripta, EarlyView.
ABSTRACT Subfamily Leuciscinae, the largest freshwater fish group of the western Palearctic region, has been widely studied, including the phylogenetic relationships between its species and genera. However, until now, one genus completely escaped attention in this regard. Even though several works hypothesised about its evolutionary relationships based

Dietary interventions in acute kidney injury: From molecular mechanism to clinical trials

open access: yesExperimental Physiology, EarlyView.
Abstract Ageing impairs renal resilience with an elevated risk of frequent and harmful acute kidney injury (AKI) that causes substantial morbidity and mortality among hospitalized patients. Since different damaging stimuli at the molecular, cellular and functional level contribute to this loss in kidney function, AKI's pathophysiology is heterogeneous ...

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Cyclic Treatment With WIN 18,446, a Potential Male Contraceptive, is as Effective as Continuous Treatment for Suppression of Spermatogenesis in Mice

open access: yesAndrology, Volume 14, Issue 6, Page 1472-1478, September 2026.
ABSTRACT Background Retinoic acid plays a critical role in spermatogenesis during both spermatogonial differentiation and spermiation. Mice lacking enzymes that synthesize retinoic acid, Aldh1a1/1a2, in the testes are infertile. WIN 18,446 reversibly inhibits spermatogenesis by inhibiting ALDH1A1/1A2 and is a promising approach to male contraception ...

CLRN1 Variants in Müller Cells Cause Mitochondrial Dysfunction in USH3A Retinal Organoids

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 8, August 2026.
We generated retinal organoids from a patient with USH3A and performed single‐cell RNA sequencing. CLRN1 was specifically expressed in Müller cells, where its variants led to mitochondrial dysfunction and photoreceptor degeneration. ABSTRACT Background Usher syndrome 3A (USH3A), caused by mutations in the CLRN1 gene, leads to retinitis pigmentosa and ...
