Safety and Efficacy of Loading Doses of Vitamin D: Recommendations for Effective Repletion.

Epidemiological data on vitamin D status revealed that, despite various dosage and durations of supplementation, the effectiveness often fails to achieve optimal outcomes. The need for higher doses than previously recommended was suggested, but several modifying factors should be considered, including the level of deficiency, and BMI. The objectives of this post hoc evaluation are to characterize treatment effectiveness based on the applied dose, duration and BMI; and to assess the safety aspects associated with rapid repletion of vitamin D.

Moculus: an immersive virtual reality system for mice incorporating stereo vision.

Due to technical roadblocks, it is unclear how visual circuits represent multiple features or how behaviorally relevant representations are selected for long-term memory. Here we developed Moculus, a head-mounted virtual reality platform for mice that covers the entire visual field, and allows binocular depth perception and full visual immersion. This controllable environment, with three-dimensional (3D) corridors and 3D objects, in combination with 3D acousto-optical imaging, affords rapid visual learning and the uncovering of circuit substrates in one measurement session.

Analysis of factors influencing the dose of levothyroxine treatment in adequately controlled hypothyroid patients of different etiologies.

Objective: The mainstay therapy of hypothyroidism is levothyroxine (LT4). In most cases lifelong treatment is warranted, therefore, choosing adequate doses are of paramount significance. The purpose of this study was to assess several factors that have been proposed to influence LT4 therapy including etiology of hypothyroidism, gender, age, bodyweight, BMI, concomitant drug use, disease severity and time since diagnosis in patients with stable, adequately controlled hypothyroidism.

Descriptive Analysis of Common Fusion Mutations in Papillary Thyroid Carcinoma in Hungary.

Thyroid cancer is the most common type of endocrine malignancy. Papillary thyroid carcinoma (PTC) is its predominant subtype, which is responsible for the vast majority of cases. It is true that PTC is a malignant tumor with a very good prognosis due to effective primary therapeutic approaches such as thyroidectomy and radioiodine (RAI) therapy.

MicroRNA Profiling in Papillary Thyroid Cancer.

Genetic alterations are well known to be related to the pathogenesis and prognosis of papillary thyroid carcinoma (PTC). Some miRNA expression dysregulations have previously been described in the context of cancer development including thyroid carcinoma. In our study, we performed original molecular diagnostics on tissue samples related to our own patients.
