The activity of hyaD contributed to the virulence of avian Pasteurella multocida.

Fowl cholera is an infectious disease that affects both poultry and wild birds, characterized by hemorrhagic and septicemic symptoms, caused by Pasteurella multocida (P. multocida), and leading to substantial economic losses in the poultry sector. The development of genetic engineering vaccines against avian P.

Investigating the technology of UV nanosecond laser milling for cutting CFRP laminates.

An enhanced ultraviolet (UV) nanosecond laser milling cutting method is innovatively adopted to cut carbon fiber reinforced plastic (CFRP) composites. This paper aims to achieve a more efficient and facile way to cut the thicker sheet cutting mode. The technology of UV nanosecond laser milling cutting is studied in detail.

Enhanced 2D finite element model and its application in laser cutting of carbon fiber reinforced plastic composites.

A tailored 2D finite element model (FEM) is proposed to describe the temperature distribution and stress distribution by the UV nanosecond pulsed laser cutting of carbon fiber reinforced plastic (CFRP) composites. This model coupled thermodynamic and thermal stress and considers the heat conduction, thermal stress, and heat flux effects during the UV laser cutting of CFRP composites. In this study, the main mechanism of UV laser cutting of CFRP is elucidated, such as pressure gradient, plasma, and vaporization effects.

IL-18 Signaling Is Essential for Causing Streptococcal Toxic Shock-like Syndrome (STSLS).

() is an emerging zoonotic pathogen that can cause multiple diseases, including streptococcal toxic shock-like syndrome (STSLS). The SC-19 strain could cause NOD-like receptor thermal protein domain-associated protein 3 (NLRP3) inflammasome hyperactivation, then induce a cytokine storm and STSLS. Although IL-18 is the downstream effector of NLRP3 signaling, the role of IL-18 signaling on STSLS remains to be elucidated.
