Analysis of Residence Time, Effective Half-Life, and Internal Dosimetry Before Radioiodine Therapy.

Radioiodine therapy has been widely used for ablation of remnant tissue after surgical treatment of differentiated thyroid carcinoma (DTC). Internal dosimetry provides a new approach to choosing the administered activity-an approach that considers the distribution and retention of I individually per patient. This study used clinical techniques of internal dosimetry to assess the accumulated activity, internal bone marrow dosimetry, and effective half-life in patients undergoing treatment for DTC.

Pediatric liver transplantation activity in a high-volume program during the COVID-19 pandemic in Brazil.

Background: The impact of the COVID pandemic on liver transplant (LT) programs varied among countries. Few data are available about that impact in pediatric liver transplant (PLT) programs. This study aimed at comparing the data of our program in Brazil (2019 vs.

Effects of Sesame ( L.) Supplementation on Creatine Kinase, Lactate Dehydrogenase, Oxidative Stress Markers, and Aerobic Capacity in Semi-Professional Soccer Players.

Nutritional intervention with antioxidants rich foods has been considered a strategy to minimize the effects of overtraining in athletes. This experimental, randomized, and placebo-controlled study evaluated the effects of consumption of sesame ( L.) on muscle damage markers, oxidative stress, systemic inflammation, and aerobic performance in male semi-professional soccer players.

Supplementation with Watermelon Extract Reduces Total Cholesterol and LDL Cholesterol in Adults with Dyslipidemia under the Influence of the MTHFR C677T Polymorphism.

Unlabelled: Dyslipidemia and genetic polymorphisms are associated with increased risk for developing cardiovascular diseases, and watermelon appears to have the potential to improve hyperlipidemia due to the presence of nutrients such as arginine and citrulline.

Objective: To test the hypolipidemic effect of watermelon extract (Citrullus lanatus) and the influence of the methylenetetrahydrofolate reductase genotype (MTHFR C677T) on supplementation response.

Methods: This is an experimental clinical phase II randomized and double-blind study.

Resistance exercise with different volumes: blood pressure response and forearm blood flow in the hypertensive elderly.

Background: The purpose of this study was to evaluate the effect of two sessions of resistance exercise with different volumes on post-exercise hypotension, forearm blood flow, and forearm vascular resistance in hypertensive elderly subjects.

Methods: The study was conducted with ten hypertensive elderly (65±3 years, 28.7±3 kg/m(2)) subjected to three experimental sessions, ie, a control session, exercise with a set (S1), and exercise with three sets (S3).

Anabolic-androgenic steroid use among Brazilian bodybuilders.

This cross-sectional, quantitative, exploratory study investigated the prevalence and profile of anabolic-androgenic steroids (AAS) users amongst a convenience sample of 510 bodybuilders from 52 gyms, in João Pessoa, Brazil, with a structured questionnaire containing selected questions about socioeconomic and training variables on the use of AAS. Data were analyzed using frequency and chi-square tests. AAS prevalence use was 20.

Adverse cardiovascular effects from the use of anabolic-androgenic steroids as ergogenic resources.

This review evaluates the documented cardiovascular functioning among anabolic-androgenic steroid (AAS) users. AAS users manifest a reduction in HDL cholesterol, increased inflammatory markers, and oxidative stress. Strong evidence associating AAS use with blood pressure at hypertensive levels, as well as hypertrophy and cardiac dysfunction has also been reported.

High-intensity exercise promotes postexercise hypotension greater than moderate intensity in elderly hypertensive individuals.

Objective: To evaluate the effects of high-intensity resistance exercise on postexercise hypotension (PEH) and forearm vascular resistance (FVR) in the hypertensive elderly.

Methodology: The study was conducted with ten hypertensive elderly individuals (65 ± 3 years, 28·7 ± 3 kg m(-2)). They were subjected to three experimental sessions: control session (SC), exercise 50% (S50%) and 80% (S80%) of 1RM.
