Possible brain regions involved in parturition in mice.

Parturition is a vital physiological process in the reproduction of female mammals, regulated by neurohumoral mechanisms coordinated by the central nervous system. The uterus is essential for this process; however, the neural pathways connecting the brain to the uterus remain poorly understood. In this study, we combined the pseudorabies virus (PRV) tracing tool with c-Fos immunofluorescence staining to identify brain regions that may regulate uterine muscle activity during parturition.

Medical management of a child treated for two unique envenomation episodes via captive snakes in a 60-day period: A case report.

Venomous snake bites can result in irreversible damage, leading to respiratory dysfunction, bleeding disorders, kidney damage, or serious complications. In recent years, with the popularity of online shopping in China, snakes can be easily purchased and kept as pets, even if some areas are not natural habitats for certain kinds of snakes. A 13-year-old boy purchased two venomous snakes online as pets.

Precise p-type and n-type doping of two-dimensional semiconductors for monolithic integrated circuits.

The controllable fabrication of patterned p-type and n-type channels with precise doping control presents a significant challenge, impeding the realization of complementary metal-oxide-semiconductor (CMOS) logic using a single van der Waals material. However, such an achievement could offer substantial benefits by enabling continued transistor scaling and unprecedented interlayer interconnect technologies. In this study, we devise a precise method for two-dimensional (2D) semiconductor substitutional doping, which allows for the production of wafer-scale 2H-MoTe thin films with specific p-type or n-type doping.

On the remarkable resistance to oxidation by the Bi cluster.

The reactivity of Bi clusters ( = 2 to 30) with O is found to display even-odd alternations. The open-shell even-sized Bi clusters are more reactive than the closed-shell odd-sized clusters, except Bi, which exhibits no observable reactivity toward O. We have investigated the structure and bonding of Bi to understand its remarkable resistance to oxidation.
