Aflatoxin B1 Promotes Pyroptosis in IPEC-J2 Cells by Disrupting Mitochondrial Dynamics through the AMPK/NLRP3 Pathway.

Aflatoxin B1 (AFB1) is one of the most toxic mycotoxins in food and feed, seriously jeopardizing the intestinal health, while the effects of AFB1 on intestinal damage remain to be well understood. This study aims to evaluate the effect of AFB1 on intestinal injury by regulating AMP-activated protein kinase (AMPK)-mediated pyroptosis . The present study showed that AFB1 led to the formation of large number of bubble-like protrusions on the cell membrane, releasing lactate dehydrogenase (LDH) and interleukin-1β (IL-1β).

Progesterone Promotes In Vitro Maturation of Domestic Dog Oocytes Leading to Successful Live Births.

Gene-edited dogs are promising models for biomedical research because they have hundreds of genetic diseases that are similar to humans. A common method for producing gene-edited dogs is assisted reproductive technology (ART) using in vivo oocytes or embryos, but it is much more inefficient and has a higher cost. ART for dogs has lagged mostly because of the lack of an efficient in vitro maturation system.

Meta-analysis of segmentectomy versus wedge resection in stage IA non-small-cell lung cancer.

Background: Although limited resection was once considered the surgical treatment for patients with Phase IA non-small-cell lung cancer (NSCLC), there has been an ongoing controversial surgical indication for wedge resection and segmentectomy in recent years. The objective of this study was to compare overall survival (OS) and disease-free survival (DFS) of segmentectomy and wedge resection for early stage NSCLC, using a meta-analysis.

Methods: Systematic research was conducted using four online databases to search for studies published before 2017.
