Blocking TSP1 Ameliorates Diabetes Mellitus-Induced Erectile Dysfunction by Inhibiting the TGF-β/SMAD Pathway.

Purpose: To examine the role and mechanism of thrombospondin-1 (TSP1) in the development of fibrosis in diabetes mellitus-induced erectile dysfunction (DMED).

Materials And Methods: DMED was induced by intraperitoneal streptozotocin injection. All rats were categorized into three groups: control group (n=8), DMED group (n=8) and DMED+Leu-Ser-Lys-Leu (LSKL) group (n=8).

Installing a Trigger to Upcycle High-Density Polyethylene.

Creating C═C bonds as "weak" sites in the stable C-C chains of polyethylene (PE) is an appealing strategy to promote sustainable development of the polyolefin industry. Compared to methods, such as dehydrogenation and postpolymerization modification, the copolymerization of ethylene (E) and butadiene (BD) should be a convenient and direct approach to introduce C═C bonds in PE, whereas it encounters problems in controlling the composition and regularity of the copolymer due to the mismatched activities and mechanisms between the two monomers. Herein, we report by employing the amidinate gadolinium complex, controllable E/BD copolymerization was achieved, where BD was incorporated in the uniformly discrete 1,4 mode.

Characteristics and functions of volatile organic compounds in the tripartite symbiotic system of HPDA25.

Tripartite interactions among plants, fungi, and bacteria are critical for maintaining plant growth and fitness, and volatile organic compounds (VOCs) play a significant role in these interactions. However, the functions of VOCs within the niche of mycoheterotrophic plants, which represent unique types of interactions, remain poorly understood. , a mycoheterotrophic orchid species, forms a symbiotic relationship with specific species, serving as a model system to investigate this intriguing issue.

Genome-wide identification of Fisch. MAPK gene family and expression analysis under salt stress relieved by .

Research on , a nonhalophyte that thrives in saline-alkaline soil and a traditional Chinese medicinal component, is focused on improving its ability to tolerate salt stress to increase its productivity and preserve its "Dao-di" characteristics. Furthermore, the inoculation of bioagents such as to increase plant responses to abiotic stressors is currently a mainstream strategy. Mitogen-activated protein kinase (MAPK), a highly conserved protein kinase, plays a significant role in plant responses to various abiotic stress pathways.
