Xenogeneic Mitochondrial Transplantation Improves Selected Age‐Associated Phenotypes in Mice
Advanced Science, EarlyView.Yak‐derived xenogeneic mitochondrial transplantation improves selected age‐associated phenotypes in mice, enhances mitochondrial functional readouts, and engages host mitochondrial quality‐control pathways. Broad tissue biodistribution, increased ATP production and mtDNA copy number, reduced ROS levels and dysfunctional mitochondria, improved motility ...

Practical problems in the posthumous retrieval of sperm [PDF]
Human Reproduction, 2014 This communication discusses the practical problems that arise during the collection and processing of sperm that have been retrieved posthumously. It is based on a small group, namely the last six men from whom we carried out posthumous retrieval. The reason for each retrieval, the method of that retrieval, the assessment of the sperm retrieved, the ...

PDIA6–SCD1 Axis Rewires Lipid Metabolism to Drive Gastric Cancer Progression
Advanced Science, EarlyView.Protein disulfide isomerase A6 (PDIA6) is identified as an oncogenic driver in gastric cancer. PDIA6 directly binds and stabilizes SCD1 by limiting its ubiquitin–proteasome‐mediated degradation, thereby sustaining monounsaturated fatty acid (MUFA)‐enriched lipid homeostasis and lipid metabolic reprogramming.

Utility of micro-TESE in the most severe cases of non-obstructive azoospermia
Upsala Journal of Medical Sciences, 2020 The use of intracytoplasmic sperm injection (ICSI) has been a major breakthrough in the treatment of male infertility. Even patients with non-obstructive azoospermia (NOA) may benefit from the ICSI technique to father a child as long as spermatogenesis ...

Development of a nomogram for sperm retrieval at microTESE for idiopathic non-obstructive azoospermia in a multi-center cohort study. [PDF]
AndrologyAbstract Background Non‐obstructive azoospermia (NOA) affects approximately 10% of infertile men and represents a major challenge in assisted reproductive technology (ART). A model that includes histological variants could be helpful in predicting sperm retrieval rate (SRR) after microdissection testicular sperm extraction (mTESE) in patients affected ...
