Directed Navigation of Magnetotactic Bacteria via Magnetotaxis in a 3D Vasculature‐On‐A‐Chip

Advanced Materials Technologies, EarlyView.
A perfusable vascular network is developed to investigate MTB at the single‐microorganism level. MTB is demonstrated to successfully align and navigate along the magnetic field inside the microvessels. Abstract Magnetotactic bacteria (MTB), inherently motile and self‐powered, are promising biorobotic candidates for targeted anti‐cancer drug delivery ...

A genetic basis for a postmeiotic X versus Y chromosome intragenomic conflict in the mouse. [PDF]

, 2012
Intragenomic conflicts arise when a genetic element favours its own transmission to the detriment of others. Conflicts over sex chromosome transmission are expected to have influenced genome structure, gene regulation, and speciation.

IL1R2 Marks and Sorts a Spermatogonial Stem Cell Population Critical for Restoring Spermatogenesis Upon Interruption in Mammals

Advanced Science, EarlyView.
Spermatogonial stem cells (SSCs) provide critical support to spermatogenesis. Here, the author established Il1r2 as a sorting marker for SSCs, with which further insights into the SSC heterogeneity and dynamic features can be obtained. They also confirmed findings in both mouse and human, thus validating IL1R2 as the surface marker for isolating and ...

Semen Characteristics of Local Breeder Cocks in the Sahel Region of Nigeria

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 2001
Semen characteristics of local cocks (60.9 ± 10.6 weeks old) in the Sahel region of Nigeria were recorded from May to September 1998. Mean values (± SD) were: semen volume 0.28 ± 0.14 ml, sperm concentration 2.26 ± 1.08 x 109 sperm/ml, total sperm count ...

Association between ambient PM1 and semen quality: A cross-sectional study of 27,854 men in China

Environment International, 2023
Background: Exposure to ambient fine and respirable particulate matter is associated with poor sperm quality, but evidence for particulate matter with an aerodynamic diameter ≤ 1 μm (PM1) is scarce.

USP9X as a Candidate Mediator of Prenatal Aspirin‐Induced Ovarian Reserve Reduction in Offspring Mice

Advanced Science, EarlyView.
This study suggests that prenatal aspirin exposure is associated with reduced ovarian reserve in offspring, associated with HDAC1‐linked epigenetic downregulation of Usp9x as a candidate mechanism. These preclinical findings provide new insights into fetal‐origin ovarian disorders and contribute to the evidence base concerning aspirin's gestational ...

SPERMATOGENESIS INDICES IN INBRED STRAINS DD/HE AND BALB/CLAC AND THEIR F1 RECIPROCAL CROSSES

Вавиловский журнал генетики и селекции, 2014
We have shown that among 13 inbred mice strains males the DD/He strain has the lowest proportion of mobile sperm and moderate sperm count and proportion of abnormal sperm heads.

Multicolour interphase cytogenetics: 24 chromosome probes, 6 colours, 4 layers [PDF]

, 2011
From the late 1980s onwards, the use of DNA probes to visualise sequences on individual chromosomes (fluorescent in-situ hybridisation - FISH) revolutionised the study of cytogenetics.
