Imaging and Quantifying Mitochondrial Morphology in C. elegans During Aging.

Mitochondria, important cellular organelles found in most eukaryotic cells, are major sites of energy production through aerobic respiration. Beyond this well-known role as the 'cellular powerhouse,' mitochondria are also involved in many other essential cellular processes, including the regulation of cellular metabolism, proliferation, immune signaling, and hormonal signaling. Deterioration in mitochondrial function during aging or under mitochondrial stress is often characterized by distinct changes in mitochondrial morphology and volume.

Pediatric Awake Craniotomy: An Educational Review.

Background: Awake craniotomies with functional cortical mapping are performed to minimize post-operative deficits from the resection of lesions adjacent to eloquent cortex. The procedure is well-established in the adult patient population and is increasingly applied to well-selected pediatric patients. A review of recent literature demonstrated that the most commonly reported anesthetic techniques were "asleep-awake-asleep" protocols that relied on propofol, remifentanil, or fentanyl.

Review of Paratesticular Appendageal Tumors, Morphology, Immunohistochemistry, and Recent Molecular Advances.

Paratesticular tumors are a rare and varied group of neoplasms arising from the tissues surrounding the testis, including the epididymis, spermatic cord, and tunica vaginalis, representing less than 10% of intrascrotal tumors. Benign tumors such as adenomatoid tumors are common, often asymptomatic but can cause discomfort. Malignant tumors, like mesothelioma and adenocarcinomas arising from appendageal structures exhibit aggressive behavior and potential for metastasis.

Effects of asymmetric nasal high-flow cannula on carbon dioxide in hypercapnic patients: A randomised crossover physiological pilot study.

Nasal high flow (NHF) therapy is an established form of non invasive respiratory support used in acute and chronic care. Recently, a new high flow nasal cannula with asymmetric prongs was approved for clinical use. The clinical benefits of the new cannula have not yet been defined and no evidence are available on the use of asymmetric NHF support in patient with Chronic Obstructive Pulmonary Disease (COPD).
