Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

On the origin of crossover interference : a chromosome oscillatory movement (COM) model [PDF]

open access: yes, 2011
Background: It is now nearly a century since it was first discovered that crossovers between homologous parental chromosomes, originating at the Prophase stage of Meiosis I, are not randomly placed.

Analysis of Y Chromosome Microdeletion in Indonesian Males

open access: yesMakara Journal of Health Research, 2010
The aim of this study is to find out Y chromosome microdeletion in Indonesian azoospermic men. This study used the PCR method with five STS to locate deletion on three different subregions (AZFa, AZFb, and AZFc) of azoospermic men and one STS to amplify ...

THE FREQUENCY OF Y CHROMOSOME MICRODELETIONS AND CYTOGENETIC ABNORMALITIES IN CASES WITH MALE INFERTILITY FROM THRACE REGION: SINGLE CENTER EXPERIENCE

open access: yesİstanbul Tıp Fakültesi Dergisi, 2021
Objective: Genetic factors, including Y chromosome microdeletions, are responsible for about 10% of male infertility cases and are particularly associated with azoospermia or severe oligozoospermia.

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

open access: yesFEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Cytomolecular identification of individual wheat-wheat chromosome arm associations in wheat-rye hybrids [PDF]

open access: yes, 2013
Chromosome pairing in the meiotic metaphase I of wheatrye hybrids has been characterized by sequential genomic and fluorescent in situ hybridization allowing not only the discrimination of wheat and rye chromosomes, but also the identification of the

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

open access: yesFEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.
