Ultrasound-Guided Repair of the Anterior Talofibular Ligament With or Without Gould Augmentation Is Safe and Improves Clinical Outcomes for Chronic Lateral Ankle Instability: A Case Series of 49 Patients.

Objectives: We have previously shown that ultrasound-guided repair results in an accurate anchor placement and restores ankle joint stability using cadaveric models. The objective is to assess the safety and clinical outcomes of ultrasound-guided ATFL repair with or without augmentation.

Methods: Forty-nine patients with chronic lateral ankle instability underwent ultrasound-guided ATFL repair with or without augmentation.

Direct photoreception by pituitary endocrine cells regulates hormone release and pigmentation.

The recent discovery of nonvisual photoreceptors in various organs has raised expectations for uncovering their roles and underlying mechanisms. In this work, we identified a previously unrecognized hormone-releasing mechanism in the pituitary of the Japanese rice fish (medaka) induced by light. Ca imaging analysis revealed that melanotrophs, a type of pituitary endocrine cell that secretes melanocyte-stimulating hormone, robustly increase the concentration of intracellular Ca during short-wavelength light exposure.

What is the identity of Gerota fascia? Histological study with cadavers.

Objectives: The advancement of laparoscopic surgery has allowed surgeons to see finer anatomical structures during surgery. As a result, several issues have arisen regarding Gerota fascia that cannot be explained by previous interpretations, such as its various forms observed during surgery. To address these issues, we histologically examined the structure of Gerota fascia.

Functional diversification process of opsin genes for teleost visual and pineal photoreceptions.

Most vertebrates have a rhodopsin gene with a five-exon structure for visual photoreception. By contrast, teleost fishes have an intron-less rhodopsin gene for visual photoreception and an intron-containing rhodopsin (exo-rhodopsin) gene for pineal photoreception. Here, our analysis of non-teleost and teleost fishes in various lineages of the Actinopterygii reveals that retroduplication after branching of the Polypteriformes produced the intron-less rhodopsin gene for visual photoreception, which converted the parental intron-containing rhodopsin gene into a pineal opsin in the common ancestor of the Teleostei.
