Metabolically Stable Adenylation Inhibitors of Biotin Protein Ligase as Antibacterial Agents.

The antibacterial agent Bio-AMS is metabolized in vivo through hydrolysis of the central acyl-sulfamide linker leading to high clearance and release of a moderately cytotoxic metabolite . Herein, we disclose analogues designed to prevent the metabolism of the central acyl-sulfamide moiety through steric hindrance or attenuation of the acyl-sulfamide electrophilicity. was identified as a metabolically stable analogue with a single-digit nanomolar dissociation constant for biotin protein ligase (BPL) and minimum inhibitory concentrations (MICs) against and ranging from 0.

Targeting the Hh and Hippo pathways by miR-7 suppresses the development of insect wings.

Wings are important organs of insects involved in flight, mating, and other behaviors, and are therefore prime targets for pest control. The formation of insect wings is a complex process that is regulated by multiple pathways. The Hedgehog (Hh) pathway regulates the distribution of wing veins, while the Hippo pathway modulates wing size.

Neural underpinnings of a two-phase memory suppression process in the neural response to self-related and observed perspective views.

Individuals often actively suppress intrusive memories to alleviate the distress they cause and maintain mental well-being. However, those with post-traumatic stress disorder (PTSD) often exhibit difficulties particularly in inhibiting or suppressing negative memories compared to individuals without PTSD. These memories can involve a physical threat either to the individual themselves or to others.

Birth weight and ponderal index percentiles for twins based on sex and chorionicity in a center of Guangdong Province, China.

Background: Intrauterine growth restriction (IUGR) which is judged based on birth weight and gestational age, is associated with increased neonatal mobility and mortality and also has a further impact on physical and mental health during later in life. Using the birth weight percentile for singletons to assess twins might not accurately reflect the growth status of the twins; this could potentially lead to an incorrect evaluation of growth-restricted children. For a more precise assessment of twin newborns, it is beneficial to utilize twin-specific birth weight percentile curves and ponderal index (PI) curves that consider factors such as birth order and sex.

Genome-wide association study on color-image-based convolutional neural networks.

Background: Convolutional neural networks have excellent modeling abilities to complex large-scale datasets and have been applied to genomics. It requires converting genotype data to image format when employing convolutional neural networks to genome-wide association studies. Existing studies converting the data into grayscale images have shown promising.
