is a Gram-negative bacterium that thrives in extreme acidic conditions. It has emerged as a key player in biomining and bioleaching technologies thanks to its unique ability to mobilize a wide spectrum of elements, such as Li, P, V, Cr, Fe, Ni, Cu, Zn, Ga, As, Mo, W, Pb, U, and its role in ferrous iron oxidation and reduction. catalyzes the extraction of elements by generating iron (III) ions in oxic conditions, which are able to react with metal sulfides.

Matrix metalloproteinase-2 (MMP-2), a zinc-dependent enzyme, plays a critical role in the degradation and remodeling of the extracellular matrix (ECM). As a member of the gelatinase subgroup of matrix metalloproteinases, MMP-2 is involved in a variety of physiological processes, including tissue repair, wound healing, angiogenesis, and embryogenesis. It is primarily responsible for the degradation of type IV and V collagen, fibronectin, laminin, and elastin, which are essential components of the ECM.

Obligate parasites often trigger significant changes in their hosts to facilitate transmission to new hosts. The molecular mechanisms behind these extended phenotypes - where genetic information of one organism is manifested as traits in another - remain largely unclear. This study explores the role of the virulence protein SAP54, produced by parasitic phytoplasmas, in attracting leafhopper vectors.

In laser safety eyewear, due to the lack of complete blocking of ultraviolet and infrared rays, we proposed a structure based on one-dimensional multilayer composed of several layers of silicon dioxide and zirconium dioxide materials alternately behind polycarbonate lens. It is find out that the acceptance angle range to the photonic crystal is 0 to 39°. This incident angle range corresponds to the band gap of the photonic crystal.

The placenta is a temporary organ that forms during pregnancy and is essential for fetal development and maternal health. As an endocrine organ, proper placental function requires continual production, folding, and transport of proteins and lipids. Central to these processes is the endoplasmic reticulum (ER), a dynamic organelle responsible for maintaining cellular protein and lipid synthesis and processing.
