CRISPR/Cas9‐mediated Genome‐editing Reveals 10 Testis‐enriched Genes and One Non‐testis‐enriched Gene are Dispensable for Male Fecundity in Mice

open access: yesAndrology, EarlyView.
ABSTRACT Background More than 1000 genes have been identified as predominantly expressed in the human testis. Advances in gene editing technologies have enabled the rapid and efficient generation of genetically engineered mice. This approach facilitates the screening of genes essential for spermatogenesis by analyzing knockout mouse models.

Data‐driven thresholds for standardized classification of severe Alzheimer's disease neuropathology using digital neuropathology

open access: yesBrain Pathology, EarlyView.
We generated digital pathologic algorithms (AI‐based modules that can be freely shared) to: optimize the sampling (ROI) for diagnosis of ADNC‐related tau pathology; compare/transition between Aperio and HALO platforms; and rationalize severe Braak NFT staging, so that all Braak‐VI cases had dementia, and all Braak‐V cases had MCI or dementia.

Human ADAM 12 (meltrin alpha) is an active metalloprotease.

open access: yes, 1998
Udgivelsesdato: 1998-Jul-3The ADAMs (a disintegrin and metalloprotease) are a family of multidomain proteins with structural homology to snake venom metalloproteases. We recently described the cloning and sequencing of human ADAM 12 (meltrin alpha).

Cannabinoid and adenosine A2A receptor crosstalk regulates postnatal and adult hippocampal neurogenesis

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and purpose Adult neurogenesis is a tightly regulated process affected by both cannabinoid receptors (CB1 and CB2) and adenosine 2A (A2A) receptors, both of which modulate neural progenitor cell activity. While emerging evidence suggests an interaction between these neuromodulatory systems, the extent and mechanism of their interplay in ...

The discovery and development of ensifentrine: A novel inhaled dual PDE3/4 inhibitor having ‘bifunctional’ bronchodilator and anti‐inflammatory activity

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Ensifentrine (formerly called RPL 554) is a novel, first in class, inhaled bifunctional dual PDE3/4 inhibitor for the treatment of chronic respiratory diseases. Ensifentrine exhibits both bronchodilation via PDE3 inhibition and anti‐inflammatory activity via PDE4 inhibition.

Changes in gastrointestinal motility and gut hormone secretion after Roux‐en‐Y gastric bypass and sleeve gastrectomy for individuals with severe obesity

open access: yesClinical Obesity, Volume 15, Issue 2, April 2025.
Summary Background Bariatric surgery is very effective in long‐term weight management. The present study was undertaken to investigate the short‐term effects of sleeve gastrectomy (SG) and of Roux‐en‐Y gastric bypass (RYGB) on (a) gastrointestinal (GI) motility, that is gastric emptying and oro‐cecal transit time and (b) secretion of regulatory gut ...

Brain Serotonin Transporter Is Elevated in Obesity: Bayesian and Frequentist Meta‐Analyses

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims The brain plays a critical role in controlling energy balance. Previous studies have mainly focused on dopaminergic mechanisms, whereas much less attention has been paid to serotonin during the emergence of overweight and obesity. Therefore, this study investigated the association between serotonin transporter (SERT) availability and ...

Tirzepatide for Obesity in Adults ≥ 65 Years: A Post Hoc Analysis of the SURMOUNT and SUMMIT Clinical Trials

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims Tirzepatide is a once‐weekly glucagon‐like peptide‐1 (GLP‐1) and glucose‐dependent insulinotropic polypeptide (GIP) receptor agonist (RA) approved for weight management in adults with obesity. Data on older adults remain limited, however. This study aimed to examine tirzepatide's safety and efficacy in adults aged ≥ 65 years with obesity ...
