Summary: The study developed a genetically encoded fluorescent reporter, iGlow, by inserting a fluorescent protein into the third intracellular loop of GPR68, which responds to physiological GPR68 activators and synthetic agonists with specificity. iGlow activation is unaffected by pharmacological modulation of downstream G-protein signaling or disruption of actin filaments, providing a new tool for investigating GPR68-dependent signaling in health and disease.

Summary: This study investigated the characteristics of fluid flow at different scales in cancellous bone in rat femurs, as well as the effects of osteoporosis and loading frequency. The results showed that the wall fluid shear stress (FSS) around osteocytes exhibited a linear relationship with loading frequency and was smaller in the osteoporotic group. This study provides important insights into bone remodeling under cyclic loading and the development of strategies for osteoporosis treatment.

Summary: Primary bone cancers like osteosarcoma are driven by bone cells with mutations, and their behavior can be influenced by mechanical stimuli in the tumor microenvironment. Fluid flow over the cells' surface was found to change the behavior of osteosarcoma cells, potentially reducing their harmful effects. Sensitivity of bone cells to mechanical changes suggests that modulation of fluid movement or stiffness levels within tumors could be a novel consideration in developing new treatments to prevent cancer progression.

Summary: Polyphenols have no significant effects on bone mineral density in postmenopausal women, but they may have a positive impact on lumbar spine BMD in studies with a duration of 24 months or longer. Additionally, polyphenols can slightly increase bone-specific alkaline phosphatase levels and decrease pyridinoline levels.

Summary: This study reveals that fluid shear stress can eliminate the majority of suspended tumor cells and increase their nuclear size, while it has no effect on adherent tumor cells. Shear flow increases nuclear size by promoting histone acetylation, which protects suspended tumor cells from shear-induced destruction. These findings provide new insights into the mechanism of suspended tumor cells' response to shear flow and may offer new approaches for cancer cell treatment.

Summary: Atherosclerosis primarily occurs in arterial regions exposed to disturbed blood flow, while regions exposed to stable flow are protected. The study discovered that KLK10, a protein sensitive to flow, is upregulated under stable flow conditions and downregulated under disturbed flow conditions. It acts as an anti-inflammatory, barrier-protective, and anti-atherogenic factor.

Summary: We developed a pump-less directional flow recirculating organ-on-a-chip platform that creates controlled unidirectional gravity-driven flow. The platform features two organoid compartments supported by independent perfusion channels, separated by a hydrogel barrier. We demonstrated the suitability of the platform for functional culture of endothelial cells and the viability of human stem-cell derived liver organoids, as well as the circulation of immune cells in the microfluidic channels.

Summary: Osteoporosis is a systemic bone disease characterized by reduced bone mass and deterioration of bone microarchitecture. Conventional anti-osteoporotic pharmaceutics have side effects, leading many women to seek botanicals as an alternative therapy. Plant-derived compounds are being increasingly researched as potential maintenance for bone health in perimenopausal and postmenopausal women.

Summary: Postmenopausal women showed higher levels of bone turnover markers but only marginally elevated levels of sclerostin compared to premenopausal women. While there were no differences in trunk bone density between the two groups, postmenopausal women had significantly lower bone density in the hip, femoral neck, and total body.

Summary: This study investigates the impact of Low Shear Modeled Microgravity (LSMMG) culture on the colonization of Salmonella Typhimurium and human intestinal diseases. The results show that LSMMG culture enhances the colonization ability of Salmonella and that the colonization ability of the Delta hfq mutant strain is higher under LSMMG conditions compared to conventional shaking cultures. In addition, infection by Salmonella induces the expression of genes related to inflammation, tissue remodeling, and wound healing in host cells. This study expands our understanding of how physical forces can affect the early stages of human enteric salmonellosis.

Summary: In this study, the population of Diploechiniscus oihonnae from the neotype locality in Merok, Norway was described using integrative taxonomy. No differences in chaetotaxy formula were found between life stages and sex of Dpl. oihonnae. The presence of filaments at Bd in some specimens of Dpl. oihonnae appears to be random, indicating morphological variability of the species. Genetic differences between the neotypic population and specimens from other localities were low, leading to the establishment of specimens from Merok as neotype and neoparatypes of Dpl. oihonnae, with Dpl. horningi being synonymised with Dpl. oihonnae based on morphological characters.

Summary: This paper studied the tardigrades in samples of mosses and lichens collected from Ivohibory Forest in south-central Madagascar. A total of 39 tardigrade taxa were identified, with 21 of them being new records for Madagascar. Additionally, a new species of Bryodelphax beniowskii sp. nov. was described based on morphological analysis. The new species is most similar to Bry. olszanowskii and Bry. parvuspolaris, but differs from them mainly in terms of ventral plates arrangement and some other morphometric characters.

Summary: A new species, Paramacrobiotus gadabouti sp. nov., was discovered and described using morphological, morphometric, and genetic data. The species belongs to the Parmacrobiotus richtersi group and exhibits richtersi-type eggs with cap-like structures at the ends. It is most similar to Pam. alekseevi, Pam. filipi, and Pam. garynahi, but differs in egg morphology and morphometrics. Unlike other species in the group, Paramacrobiotus gadabouti sp. nov. is a parthenogenetic species with a wider distribution, supporting the hypothesis of 'everything is everywhere' for tardigrades.
