Decrease in Facial Bone Density with Aging and Maintenance Effect of Calcium Maltobionate Ingestion in Japanese Adult Women: A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Trial.

Background/objectives: Facial bone density, including the jawbone, declines earlier than that of the lumbar spine and calcaneus. Calcium maltobionate is reported to mitigate bone resorption and maintain bone density of the lumbar spine in post-menopausal women, but its effects on facial bone density remain understudied. Therefore, this study compared variations in facial bone mineral density with variations in calcaneal bone mineral density and bone resorption markers among healthy women, examining differences between pre- and post-menopause and the effects of continuous calcium maltobionate intake.

Exercise in Pediatric COVID-19: A Randomized Controlled Trial.

Purpose: This study assessed the impact of a 12-week, home-based exercise training (HBET) program on health-related quality of life (HRQOL, primary outcome), cardiovascular and metabolic parameters in pediatric COVID-19 patients.Methods: In this single-center, randomized controlled trial conducted in Sao Paulo (Brazil) from October 2020 to January 2022, 32 patients (mean age 12 ± 3.3 years; median 4 months [range: 0.

Synthesis of Arrayed Tungsten Disulfide Nanotubes.

Tungsten disulfide nanotubes (WS-NTs), with their cylindrical structure composed of rolled WS sheets, have attracted much interest because of their unique physical properties reflecting quasi-one-dimensional chiral structures. They exhibit a semiconducting electronic structure regardless of their chirality, and various semiconducting and optoelectronic device applications have been demonstrated. The development of techniques to fabricate arrayed WS-NTs is crucial to realizing the highest device performance.

Cell surface architecture of the cultivated DPANN archaeon .

The DPANN archaeal clade includes obligately ectosymbiotic species. Their cell surfaces potentially play an important role in the symbiotic interaction between the ectosymbionts and their hosts. However, little is known about the mechanism of ectosymbiosis.

Semiconducting Transition Metal Dichalcogenide Heteronanotubes with Controlled Outer-Wall Structures.

Transition metal dichalcogenide (TMDC) nanotubes exhibit unique physical properties due to their nanotube structures. The development of techniques for synthesizing TMDC nanotubes with controlled structures is very important for their science and applications. However, structural control efforts have been made only for the homostructures of TMDC nanotubes and not for their heterostructures that provide an important platform for their two-dimensional counterparts.
