A study was made into the structural-and-functional status of the osseous tissue in patients with neuroendocrinemetabolic form of the hypothealamic syndrome. Noted in the above patients were abnormalities in the calcium-phosphorous balance which are manifested by a drop in the blood level of calcium and by profound hypercalciuria. All examinees have been shown to present with the osteopenic syndrome formation. Possible causes of development of systemic osteopenia in those patients presenting with neuroendocrinemetabolic form of the hypothalamic syndrome are believed to include, in the first place, hypercorticoidism, hyperprolactinemia, reduction in the estrogen secretion, which might be result in imbalance of processes of bone remodelling involving largely resorption of the bone.

Unlabelled: During the Iron Age, north-eastern Iberian communities relied on crop cultivation and animal husbandry for their subsistence. The latter was mainly focused on caprine, with sheep being prominent due to their suitability to the Mediterranean climate, orography, and environment. Despite the pivotal role of sheep in livestock husbandry, information on Iberian communities' feeding strategies for this species is limited.

Osteochondral injuries in the knee are uncommon in the immature skeleton and are usually related to sporting activities. Fixation is required depending on the size and location of the fragment. The standard technique is open reduction and internal fixation with metal screws, which are removed in a second procedure after consolidation.

Purpose: Successful regeneration of cranial defects necessitates the use of porous bone fillers to facilitate cell proliferation and nutrient diffusion. Open porous microspheres, characterized by their high specific surface area and osteo-inductive properties, offer an optimal microenvironment for cell ingrowth and efficient ossification, potentially accelerating bone regeneration.
Materials And Methods: An in vitro investigation was conducted to assess the physicochemical properties, porosity, and biocompatibility of PHA-nano-clay open porous microspheres.

Zebrafish and medaka are valuable model vertebrates for genetic studies. The advent of CRISPR-Cas9 technology has greatly enhanced our capability to produce specific gene mutants in zebrafish and medaka. Analyzing the phenotypes of these mutants is essential for elucidating gene function, though such analyses often yield unexpected results.

The global rise in work-related musculoskeletal ailments has led to issues like neck discomfort, scapular muscle dysfunction, reduced neck mobility, and functional limitations. This study aimed to evaluate the effectiveness of scapular functional exercises (SFE) and cervical isometric exercises (CIE) on pain, cervical range of motion (CROM), and functional limitations in individuals with chronic mechanical neck pain (CMNP). A two-arm, parallel group pretest-post-test randomized comparative trial was conducted.
