SchoolAIR: A Citizen Science IoT Framework Using Low-Cost Sensing for Indoor Air Quality Management.

Indoor air quality (IAQ) problems in school environments are very common and have significant impacts on students' performance, development and health. Indoor air conditions depend on the adopted ventilation practices, which in Mediterranean countries are essentially based on natural ventilation controlled through manual window opening. Citizen science projects directed to school communities are effective strategies to promote awareness and knowledge acquirement on IAQ and adequate ventilation management.

EtHg is more toxic than MeHg to human peripheral blood mononuclear cells: Involvement of apoptotic, mitochondrial, oxidative and proliferative parameters.

Background: Methylmercury (MeHg) and ethylmercury (EtHg) are potent toxicants affecting the environment and human healthy. In this way, the present study aimed to investigate and compare the effects of MeHg and EtHg exposure on human peripheral blood mononuclear cells (PBMCs), which are critical components of the mammalian immune system.

Methods: PBMCs were exposed to 2.

Accuracy of Foot Pressure Measurement on Predicting the Development of Foot Ulcer in Patients with Diabetes: A Systematic Review and Meta-Analysis.

Objective: Areas of the foot with diabetic ulcers have been observed to have greater plantar pressures compared to non-ulcerated. Pressures play an essential role in the mechanism of lesion, and their reduction is effective in prevention. We conducted a systematic review to evaluate pedobarography as a predictive tool for ulcer development, since there is still no consensus on this aspect.

Heavy Particle Impact Vibrational Excitation and Dissociation Processes in CO.

A heavy particle impact vibrational excitation and dissociation model for CO is presented. This state-to-state model is based on the forced harmonic oscillator (FHO) theory, which is more accurate than current state-of-the-art kinetic models of CO based on first-order perturbation theory. The first excited triplet state B of CO, including its vibrational structure, is considered in our model, and a more consistent approach to CO dissociation is also proposed.

Effects of dancing compared to walking on cardiovascular risk and functional capacity of older women: A randomized controlled trial.

Introduction: Aging is characterized by reductions in lean mass simultaneously to increases in visceral adipose tissue, elevating cardiovascular risk (CVR) and physical dependence. Dancing has been recommended for improving fall-risk and CVR, however, comparisons with traditional exercises are limited. This study aimed to compare the effects of dancing with walking on CVR and functionality of older women.

Capillary glycaemia responses to strength exercises performed before or after high-intensity interval exercise in Type 1 diabetes under real-life settings.

This study investigated the influence of performing strength exercises before or after high-intensity interval exercise on glycaemia during and postexercise in T1DM patients. Nine physically active adults with T1DM executed 30 min of strength exercises (SE) (3 sets at 10 RM) before 30 min of high-intensity interval exercise (HIIE) (10 × 60-s bout at ∼90% HR interspersed with 60 s recovery) (SE + HIIE) or performed the reverse order (HIIE + SE) or rested in this period. Capillary glucose levels were measured each 15 min during and 60 min postexercise recovery.

Flattening of oxygen pulse during exercise may detect extensive myocardial ischemia.

Purpose: Flattening of oxygen pulse curve during incremental cardiopulmonary exercise testing has been proposed for the improvement of diagnostic accuracy of exercise-induced myocardial ischemia. In this study, we compare the oxygen pulse response to incremental treadmill exercise in patients with and without ischemia as detected by myocardial perfusion scintigraphy.

Methods: Eighty-seven patients referred to exercise myocardial perfusion scintigraphy were also evaluated with incremental treadmill cardiopulmonary exercise testing.
