Thick and Short Fetal Corpus Callosum on Ultrasound: Added Value of Fetal Magnetic Resonance Diffusion Tensor Imaging With Tractography.

Background: Thick fetal corpus callosum (CC) is a rare finding and its significance in isolation is not clear. In this retrospective study, we aim to gain insight into the microarchitecture of CC in a cohort of fetuses with thick and short CC (isolated or associated with mild extra-/intracranial abnormalities) as seen on ultrasound (US), by using prenatal magnetic resonance (MR) diffusion tensor imaging (DTI) with fiber tractography, thereby allowing better characterization for postnatal prognosis.

Methods: Twelve fetuses met the inclusion criteria on US.

Calcium phosphate nanoclusters modify periodontium remodeling and minimize orthodontic relapse.

Orthodontic relapse is one of the most prevalent concerns of orthodontic therapy. Relapse results in patients' teeth reverting towards their pretreatment positions, which increases the susceptibility to functional problems, dental disease, and substantially increases the financial burden for retreatment. This phenomenon is thought to be induced by rapid remodeling of the periodontal ligament (PDL) in the early stages and poor bone quality in the later stages.

Paroxysmal Hypertension in Congenital Hypothyroidism: An Unusual Case of Pheochromocytoma.

Pheochromocytomas are rare tumors arising from the chromaffin cells of the adrenal medulla that result in the secretion of excessive catecholamines. They are an uncommon cause of hypertension in the pediatric population. We present a case of a six-year-old male with hypertension, rapid weight loss, palpitations, excessive sweating, and vomiting.

Apical integrins as a switchable target to regulate the epithelial barrier.

Tight junctions regulate epithelial barrier function and have been shown to be influenced by multiple classes of proteins. Apical integrins have been identified as potential regulators of epithelial barrier function; however, only indirect approaches have been used to measure integrin regulation of the epithelial barrier. Here, we used polymeric nanowires conjugated with anti-integrin β1 antibodies to specifically target apically localized integrins in either their closed or open conformation.
