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 ...

CellPolaris: Transfer Learning for Gene Regulatory Network Construction to Guide Cell State Transitions

Advanced Science, EarlyView.
CellPolaris decodes how transcription factors guide cell fate by building gene regulatory networks from transcriptomic data using transfer learning. It generates tissue‐ and cell‐type‐specific networks, identifies master regulators in cell state transitions, and simulates TF perturbations in developmental processes.

Nurr1 Orchestrates Claustrum Development and Functionality

Advanced Science, EarlyView.
Nurr1 (Nr4a2) is the master transcription factor to control claustrum morphogenesis and cell fate decision postmitotically by inhibiting intracellular G‐protein signaling. Nurr1 deficiency alters the transcriptomic profiles of subcortical claustral neurons into neocortical insular neurons, resulting in defected claustrum development, impaired axonal ...

Sperm retrieval techniques for assisted reproduction [PDF]

International braz j urol, 2011
Different surgical methods such as PESA, MESA, TESA, TESE and micro-TESE have been developed to retrieve spermatozoa from either the epididymis or the testis according to the type of azoospermia, i.e., obstructive or non-obstructive. Laboratory techniques are used to remove contaminants, cellular debris, and red blood cells following collection of the ...

Small Nucleolar RNA Snord17 Promotes Self‐Renewal of Intestinal Stem Cells through Yy2 mRNA Export and Tead4 Activation

Advanced Science, EarlyView.
Snord17, through interaction with Thoc3, promotes nuclear export and translation of Yy2 mRNA in Snord17+/+ ISCs. The Yy2 protein subsequently binds the Tead4 promoter to promote its transcription, activating Hippo signaling, which is essential for ISC maintenance.

Factors Affecting Outcomes of Salvage Micro Testicular Sperm Extraction Following a Failed Testicular Sperm Extraction

Haseki Tıp Bülteni, 2020
Aim:To investigate the likelihood of sperm retrieval in repeated micro-testicular sperm extraction (micro-TESE) in non-obstructive azoospermia (NOA) patients.Methods:Data of 310 patients, who underwent a micro-TESE procedure at a center experienced in in

IGF‐1 Deficiency Serves as an Integrated Biomarker Pathogenic Driver and Predictor in Poor Ovarian Response

Advanced Science, EarlyView.
IGF‐1 deficiency underlies poor ovarian response (POR), as reduced levels in follicular fluid and granulosa cells impair antral follicle formation and compromise reproductive outcomes. Including IGF‐1 as a biomarker significantly enhances the accuracy of models predicting both PORrisk and pregnancy success.

Re: Comparison of Microdissection Testicular Sperm Extraction, Conventional Testicular Sperm Extraction, and Testicular Sperm Aspiration for Nonobstructive Azoospermia: A Systematic Review and Meta-Analysis

Journal of Urological Surgery, 2016
In contemporary medicine, testicular sperm extraction (TESE) and using testicular sperm for intracytoplasmic injection is the only fertility treatment in men with nonobstructive azoospermia (NOA).

Targeting the CMKLR1‐Mediated Signaling Rebalances Immunometabolism State in Middle‐Age Testicular Macrophages

Advanced Science, EarlyView.
In middle age, testicular CMKLR1⁺ macrophages exhibited a pro‐inflammatory immunometabolic profile, mediated by adipose signals associated with high BMI. However, inhibition of CMKLR1 signaling, either through Cmklr1 genetic ablation or treatment with a CMKLR1 antagonist peptide, can reverse this phenotype.

TP53BP2 Promotes Placental Autophagy and Preeclampsia via G9a and DNMT1 Cooperatively Modulating E2F1

Advanced Science, EarlyView.
G9a, and DNA Methyltransferase1 (DNMT1) cooperatively modulates E2F1 on the promoter of tumor suppressor p53‐binding protein 2 (TP53BP2) increased autophagy in preeclampsia. TP53BP2 promotes autophagy in trophoblasts through DNA methylation and H3K9me2‐mediated transcriptional regulation.
