The Impact of Body Mass Index and Benign Prostatic Hyperplasia on Bone Health of Middle-Aged and Older Men.

Objective: Osteoporosis significantly affects older adults by reducing bone mass and increasing fracture risk, thereby impacting morbidity and mortality. This study aimed to investigate the relationship between bone mineral density (BMD), body mass index (BMI), and trabecular bone score (TBS) among middle-aged and older men with or without benign prostatic hyperplasia (BPH).

Methods: A retrospective study was conducted using health examination data from male participants aged 50-98 years collected at a regional hospital in southern Taiwan.

Radar-Terahertz-Infrared Compatible Stealth Coaxial Silver Nanowire@Carbon Nano-Cable Aerogel.

Achieving multi-spectrum compatible stealth in radar-terahertz-infrared bands with robust performance has great prospects for both military and civilian applications. However, the progress of materials encounters substantial challenges due to the significant variability in frequency coupling properties across different electromagnetic wave bands. Here, this work presents the design of a multi-scale structure and fabricates a lightweight aerogel (silver nanowire@carbon, AgNW@C) consisting of a regular coaxial nano-cable, with silver nanowire as the core and amorphous-graphitized hybrid carbon as the outer-layer.

High Molecular Weight Uniform Polymers Encoding Octal Sequences by Passerini Iterative Exponential Growth.

Sequence-defined polymers composed of a large pool of chemically distinct monomers (SDPs) have been pursued to achieve the structural and functional precisions exhibited by biopolymers in nonbiological environments. In contrast to the incremental growth of SDPs by sequential addition of individual monomers, the iterative exponential growth (IEG) method allows the synthesis of high molecular-weight SDPs, but their sequences have been composed mostly of binary monomers. Consequently, achieving high molecular-weight SDPs built with a large pool of monomers remains a challenge.

Molecular and niche modeling approaches to identify potential amplifying hosts for an emerging tick-borne pathogen, Rickettsia rickettsii subsp. californica, the causative agent of Pacific Coast tick fever.

Pacific Coast tick fever is a recently described zoonotic disease in California caused by a spotted fever group rickettsia, Rickettsia rickettsii subsp. californica (formerly Rickettsia 364D) and transmitted by the Pacific Coast tick, Dermacentor occidentalis. Like many emerging vector-borne diseases, knowledge regarding the transmission cycle, contribution from potential amplifying hosts, and geographic distribution of R.
