Background: Chronic kidney disease (CKD) and type 2 diabetes mellitus (T2DM) are associated with disturbed mineral homeostasis and serum bone biomarkers. The interplay between T2DM and CKD on serum bone turnover markers (BTM) is unclear. Our aim was to describe the BTM in patients with T2DM, CKD or both.
Methods: In this observational, single-centre, prospective study, we included 320 patients over 40 years, divided into four groups: T2DM and normal kidney function (n=142), T2DM and CKD (n=36), CKD and normal glucose metabolism (n=29) and healthy controls (n=113). We excluded patients treated for osteoporosis and with secondary osteoporosis. Patients were compared by age, levels of glycated hemoglobin, PTH, alkaline phosphatase, osteocalcin (OC), CTx and 25 OH vitamin D.
Results: Univariate analysis showed that GFR correlated significantly with PTH (r=0.37), OC (r=0.43) and CTX (r=0.45) in the diabetes group but only with PTH (r=0.34) in the non-T2DM group. Multivariate analysis showed that GFR remained significantly correlated with the same bone markers even after adjustment for age, sex or 25(OH)D levels. Diabetics seem to have lower levels of alkaline phosphatase (68±22.1 U/L) and CTX (0.37±0.24 ng/mL) than those without diabetes (76.7±29.6. U/L and 0.5±0.19 ng/mL, respectively). There was no correlation between BTM and glycated hemoglobin.
Conclusions: Bone turnover markers correlate with GFR, particularly in patients with T2DM. However, alkaline phosphatase is lower in T2DM than in non-T2DM.

Aortic aneurysm is a life-threatening disease caused by progressive dilation of the aorta and weakened aortic walls. Its pathogenesis involves an imbalance between connective tissue repair and degradation. CD34 cells comprise a heterogeneous population that exhibits stem cell and progenitor cell properties.

Although senescent cells can be eliminated by the immune system, they tend to accumulate with age in various tissues. Here we show that senescent cells can evade immune clearance by natural killer (NK) cells by upregulating the expression of the disialylated ganglioside GD3 at their surface. The increased level of GD3 expression on senescent cells that naturally occurs upon aging in liver, lung, kidney or bones leads to a strong suppression of NK-cell-mediated immunosurveillance.

Metabolic pathways exhibit fluctuating activities during bone and dental loss and defects, suggesting a regulated metabolic plasticity. Skeletal remodeling is an energy-demanding process related to altered metabolic activities. These metabolic changes are frequently associated with epigenetic modifications, including variations in the expression or activity of enzymes modified through epigenetic mechanisms, which directly or indirectly impact cellular metabolism.

Unlabelled: This study examines how power training affects estimated bone strength, revealing that females benefit more than males, especially in the upper limbs (radius). These findings highlight the importance of designing sex-specific exercise programs to enhance bone health. Further research is needed to optimize training duration and address site-specific differences.

Purpose: We aimed to investigate early effects of regulating alpha‑7 nicotinic acetylcholine receptor (α7nAChR) agonists and antagonists on maxillary expansion in mice.
Methods: We allocated 36 six-week-old male C57BL/6J mice into three group: 1) expansion alone, 2) expansion plus the α7nAChR-specific agonist 3‑(2,4-dimethoxybenzylidene)-anabaseine dihydrochloride (GTS-21), and 3) expansion plus alpha-bungarotoxin (α-BTX), a competitive antagonist of α7nAChR. The groups were daily injected with saline, GTS-21 (4 mg/kg/day) or α‑BTX (1 mg/kg/day), respectively, from days 0-7.
