The forest region of the Ranchi District of Jharkhand, India, is rich with various wild mushrooms. Of the 200 samples collected, 9 species were identified and subjected to medicinal studies. For antibacterial assay, 4 strains of bacteria (namely, Escherichia coli, Salmonella typhi, Pseudomonas fluorescens, and P. putida) were used. For antifungal assay, 4 strains of fungi (namely, Aspergillus niger, A. flavus, Microsporum canis, and Cladosporium herbarum) were used. Also, tests such as the α-amylase inhibition assay, a measure of antidiabetes activity, and antioxidant assays such as the DPPH, ferric-reducing antioxidant power, and acetylcholinesterase-inhibitory assays, which determine anti-Alzheimer disease properties, were carried out. Agaricus bisporus, A. campestris, Russula cyanoxantha, and Amanita pantherina all showed a maximal zone of inhibition against P. putida and M. canis. Ganoderma lucidum, Astraeus hygrometricus, and R. emetica all showed a maximal zone of inhibition against E. coli and A. flavus. Pleurotus populinus showed a maximal zone of inhibition against P. fluorescens and C. herbarum. P. pulmonarius showed a maximal zone of inhibition against S. typhi and M. canis. Also, all the collected samples showed α-amylase-inhibitory activity. A. hygrometricus showed maximal DPPH activity and ferric-reducing antioxidant power, whereas A. bisporus showed maximal acetylcholinesterase inhibitory activity.

A New target of ischemic ventricular arrhythmias-ITFG2.
Eur J Pharmacol

ITFG2 is an intracellular protein known to modulate the immune response of T-cells. Our previous investigation revealed that ITFG2 specifically targets ATP5b to regulate ATP energy metabolism and maintain mitochondrial function, thereby protecting the heart from ischemic injury. However, the role of ITFG2 in ischemic ventricular arrhythmias and its underlying mechanisms have not been previously reported.

Materials (Basel)
January 2025
School of Civil Engineering, Nanjing Tech University, Nanjing 211816, China.
The issues of numerous steel beam components and the tendency for deck cracking under negative bending moment zones have long been challenges faced by traditional composite I-beams with flat steel webs. This study introduces an optimized approach by modifying the structural design and material selection, specifically substituting flat steel webs with corrugated steel webs and using ultra-high-performance concrete for the deck in the negative bending moment zone. Three sets of model tests were conducted to compare and investigate the influence of deck material and web forms on the bending and crack resistance of steel-concrete composite I-beams under a negative bending moment zone.

Ecosystem water use efficiency (WUE) and carbon use efficiency (CUE) are critical parameters to determine the trade-off between water consumption and carbon sequestration in drylands. However, the roles of vegetation cover, climate factors and soil moisture in affecting the coupling of WUE and CUE were still poorly understood. This study combined the spatial random forest model and structural equation model to detect the drivers of WUE and CUE variations in China's Loess Plateau during 2001-2020, a typical water-limited region with about 87 % of area experiencing significant vegetation greening.

Background: Prone transpsoas lumbar interbody fusion (PTP) is a newer technique to treat various spinal disc pathologies. PTP is a variation of lateral lumbar interbody fusion (LLIF) that is performed with the patient prone rather than in the lateral decubitus position. This approach offers similar benefits of lateral spinal surgery, which include less blood loss, shorter hospital stay, and quicker recovery compared with traditional open spine surgery.

Background: HA14-1 is a small-molecule, stable B-cell lymphoma 2 (Bcl-2) antagonist that promotes apoptosis in malignant cells through an incompletely-defined mechanism of action. Bcl-2 and related anti-apoptotic proteins, such as B-cell lymphoma-extra-large [Bcl-XL]), are predominantly localized to the outer mitochondrial membrane, where they regulate cell death pathways. However, the notably short half-life of HA14-1 limits its potential therapeutic application.
