Whole-Body Vibration Associated with Strength Training on the Lower-Limb Blood Flow and Mobility in Older Adults with Type 2 Diabetes: A Study Protocol for a Randomized Controlled Trial.

Vascular endothelium insults caused by high serum glucose levels affect the oxygen supply to tissues, via the microvascular endothelium, resulting in an increased perfusion heterogeneity. These insults may lead to the underuse of blood capillaries, while other vessels are overused and effectively overload their oxygen supply capacity, which eventually causes damages to distal parts of the peripheral nervous system. Therefore, the proprioceptive and exteroceptive feedback information will be gradually lost and contribute to a mobility reduction.

Effectiveness of Whole-Body Vibration Combined with Multicomponent Training on the Risk of Falls and Quality of Life in Elderly Women with Osteoporosis: Study Protocol for a Randomized Controlled Clinical Trial.

Osteoporosis and the risk of falls increase the risk of fractures and events of falls. Prescriptions and programs for different forms of exercise have different impacts on the risk of falls, and exercises from multiple categories of whole-body vibration can be effective. This study aims to evaluate the effectiveness of whole-body vibration (WBV) protocol combined with multicomponent training (MCT) in elderly women with osteoporosis and their history of falls.

Prevalence of COVID-19 in children, adolescents and adults in remote education situations in the city of Fortaleza, Brazil.

Objectives: A retrospective study was conducted to identify the prevalence of COVID-19 through serology and RT-PCR in children, adolescents and adults. A database of the COVID-19 Tracking Program in school children was used.

Methods: The data comprised sociodemographic and clinical variables, results of serological tests (IgM and IgG), and real-time-polymerase chain reaction (RT-PCR) results of IgM-positive individuals.

Arabidopsis protochlorophyllide oxidoreductase A (PORA) restores bulk chlorophyll synthesis and normal development to a porB porC double mutant.

In angiosperms the strictly light-dependent reduction of protochlorophyllide to chlorophyllide is catalyzed by NADPH:protochlorophyllide oxidoreductase (POR). The Arabidopsis thaliana genome encodes three structurally related but differentially regulated POR genes, PORA, PORB and PORC. PORA is expressed primarily early in development-during etiolation, germination and greening.

2-Benzoyl-pyridine semicarbazone.

The title compound, C(13)H(12)N(4)O, crystallizes with two independent mol-ecules in the asymmetric unit. The compound crystallizes as the ZE isomer, where Z and E refer to the configuration around the C=N and N-C bonds, respectively, with an N-H⋯N(py) (py is pyridine) intra-molecular hydrogen bond. The dihedral angles between the least-squares planes through the semicarbazone group and the pyridyl ring are 22.

[Attention deficit/hyperactivity disorder prevalence in an inner city elementary school].

Objective: To define the prevalence of attention deficit/hyperactivity disorder (ADHD) in a sample school-aged children from a public elementary school.

Method: The study population was composed of all pupils who attended the first five grades at a public state school. During the first stage, school teachers and parents filled a standardized questionnaire of 18 ADHD symptoms defined at DSM-IV.
