Alginate-HEMA Hydrogels as Promising Biomaterials for Bone Regeneration: In Vitro and In Vivo Studies.

In the present work, the osteogenic and angiogenic properties of, previously developed, semi-interpenetrated HEMA-EGDMA polymeric networks (sIPN) with and without alginate with application in bone tissue engineering (BTE) were studied. In vitro characterization studies were performed using rat bone marrow progenitor cells (BMPCs), EA.hy926 endothelial cells, and rat vascular smooth muscle cells (VSMCs).

Amino acid-specific isotopes reveal changing five-dimensional niche segregation in Pacific seabirds over 50 years.

Hutchison's niche theory suggests that coexisting competing species occupy non-overlapping hypervolumes, which are theoretical spaces encompassing more than three dimensions, within an n-dimensional space. The analysis of multiple stable isotopes can be used to test these ideas where each isotope can be considered a dimension of niche space. These hypervolumes may change over time in response to variation in behaviour or habitat, within or among species, consequently changing the niche space itself.

[Neurosarcoidosis: Onset with involvement of multiple neurological sites].

We present the case of a healthy young woman who consulted for left peripheral facial palsy associated with fever, dry cough, dyspnea, and asthenia of two weeks' evolution. Physical examination revealed hypoesthesia in left T6 to T12 dermatomes and bilateral galactorrhea. In the laboratory, she presented negative viral serology, elevated erythrocyte sedimentation rate, antinuclear antibody titers, prolactin and thyroid-stimulating hormone, with positive antiperoxidase antibodies.

Consensus recommendations on mental health issues in Phelan-McDermid syndrome.

Phelan-McDermid syndrome is a rare genetic condition caused by a deletion encompassing the 22q13.3 region or a pathogenic variant of the gene SHANK3. The clinical presentation is variable, but main characteristics include global developmental delay/intellectual disability (ID), marked speech impairment or delay, along with other features like hypotonia and somatic or psychiatric comorbidities.
