Ultrasound imaging of the jawbone is not currently used in dental medicine to determine bone density. Bone-marrow defects in the human jawbone (BMDJ/FDOJ) are widely discussed in dentistry owing to their role in implant failures and as sources of inflammation in various immune diseases. The use of through-transmission alveolar ultrasonography (TAU) to locate BMDJ/FDOJ was evaluated in this study using a new TAU apparatus (TAU-n). The objective was to determine whether TAU-n readings accurately indicate the clinical parameters to detect BMDJ/FDOJ. Three parameters were compared with TAU-n measurements: 2-D orthopantomogram, Hounsfield units using digital volume tomography and post-operatively measured levels of RANTES/CCL5 expression in BMDJ/FDOJ samples. Based on the available clinical data, Hounsfield units, RANTES/CCL5 expression and TAU-n color codes yielded consistent results with respect to bone mineral density. Thus, ultrasonography with TAU-n is a reliable and efficient diagnostic method to screen for BMDJ/FDOJ in dentistry.

Hepatosplenic T-cell lymphoma (HSTCL) is an aggressive mature T-cell lymphoma characterized by significant hepatosplenomegaly, bone marrow involvement, and minimal or no lymphadenopathy. Primarily affecting young adults, it is exceptionally rare in children and adolescents. This makes diagnosis and treatment particularly challenging for pathologists and pediatric oncologists.

Age-induced abnormalities in bone metabolism disrupt the equilibrium between bone resorption and formation. This largely stems from disturbances in bone homeostasis, in which signaling pathways exert a significant regulatory influence. Aging compromises the functionality of the bone marrow mesenchymal stem cells (BMSCs), ultimately resulting in tissue dysfunction and pathological aging.

Background Vitamin B12 deficiency, or cobalamin deficiency, is common among populations with low consumption of animal-based products, mainly in India, due to religious and socioeconomic factors, which significantly increase the deficiency rate. The condition has been characterized by a wide range of clinical and hematological symptoms, mainly affecting the blood and nervous system. This study aims to assess the clinical and hematological characteristics of patients with vitamin B12 deficiency and assess the therapeutic response to supplementation with vitamin B12.

Well-designed artificial scaffolds are urgently needed due to the limited self-repair capacity of bone, which hampers effective regeneration in critical defects. Optimal scaffolds must provide physical guidance to recruit cells and immune regulation to improve the regenerative microenvironment. This study presents a novel scaffold composed of dual-sided centripetal microgrooved poly(D,L-lactide-co-caprolactone) (PLCL) film combined with a dynamic hydrogel containing prednisolone (PLS)-loaded Prussian blue nanoparticles (PB@PLS).
