The effect of physical cues on platelet storage lesion.
Hematology

Department of Blood Transfusion, First Affiliated Hospital, Third Military Medical University (Army Medical University), Chongqing, People's Republic of China.
Background: Platelet concentrates play an important role in clinical treatment such as platelet function disorders and thrombocytopenia. In the process of preparation and storage of platelets, centrifugation, leukofiltration, and agitation will cause morphological changes and impaired function of platelets, which is associated with the increase of platelet transfusion refractoriness, and named as platelet storage lesion (PSL).
Method: This paper proposes three major operations (centrifugation, agitation, and leukofiltration) that platelets experience during the preparation and storage process, to explore the effect of physical cues on PSL.
TGR5 attenuates DOCA-salt hypertension through regulating histone H3K4 methylation of ENaC in the kidney.

Epithelial sodium channel (ENaC), located in the collecting duct principal cells of the kidney, is responsible for the reabsorption of sodium and plays a critical role in the regulation of extracellular fluid volume and consequently blood pressure. The G protein-coupled bile acid receptor (TGR5) is a membrane receptor mediating effects of bile acid and is implicated in kidney diseases. The current study aims to investigate whether TGR5 activation in the kidney regulated ENaC expression and potential mechanism.

Advanced Institute for Materials Research (WPI-AIMR), Tohoku University, Katahira 2-1-1, Aoba-ku, Sendai 980-8577, Japan.
Sodium borohydride dihydrate (NaBH·2HO) forms through dihydrogen bonding between the hydridic hydrogen of the BH ion and the protonic hydrogen of the water molecule. High-pressure structural changes in NaBH·2HO, observed up to 11 GPa through X-ray diffraction and Raman scattering spectroscopy, were analyzed to assess the influence of dihydrogen bonds on its crystal structure. At approximately 4.

Concurrent superconductivity and negative photoconductivity (NPC) are rarely observed. Here, the discovery in PbSeTe of superconductivity and photoconductivity transitions between positive photoconductivity (PPC) and NPC during compression is reported to ≈40 GPa and subsequent decompression, which are also accompanied by reversible structure transitions (3D Fm m ⇌ 2D Pnma ⇌ 3D Pm m). Superconductivity with a maximum T of ≈6.

High pressure can create extreme conditions that enable the formation of novel materials and the discovery of new phenomena. However, the ability to preserve the desirable characteristics of materials obtained under high pressure has remained an elusive challenge, as the pressure-induced changes are typically reversible, except for the pressure-induced chemical reactions such as polymerization of hydrocarbons. Here, we propose the concept of "pressure aging" (PA) that enables the permanent locking-in of high-pressure structures and their associated enhanced properties in functional materials.
