Este artigo ressalta três principais pontos relativos à antecipação de vulnerabilidades e mudanças climáticas em contextos urbanos. Primeiro, a mudança climática é uma questão ecológica bem como um problema ambiental, e sua melhoria requer uma…

The aim of this case series is to describe and evaluate our experience of continuous positive airway pressure (CPAP) to treat type 1 respiratory failure in patients with COVID-19. CPAP was delivered in negative pressure rooms in the newly repurposed…

El cambio climático, el efecto invernadero, el agujero de la capa de ozono, la acidificación del suelo y el agua, el agotamiento de los recursos no renovables y la contaminación de las aguas y de los suelos son factores que han aumentado la…

Existe evidencia de que gran parte del cambio climático es causado por las emisiones de gases de efecto invernadero (GHG), siendo la vitivinicultura una de las actividades responsables. El uso del combustible en la maquinaria agrícola, el empleo de…

We report here a novel method for predicting melting temperatures of DNA sequences based on a molecular-level hypothesis on the phenomena underlying the thermal denaturation of DNA. The model presented here attempts to quantify the energetic…

The degradation of Reactive Red 120 dye (RR-120) in synthetic waters was studied. Two processes were considered: homogeneous sono-Fenton with iron(II) sulfate and heterogeneous sono-Fenton with synthetic goethite and goethite deposited onto silica…

An essential effect of environmental stiffness on biological processes in cells at present is generally accepted. An increase in arterial stiffness with advanced age has been reported in many publications. The aim of the present review is to…

One year since the first severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was reported in China, several variants of concern (VOC) have appeared around the world, with some variants seeming to pose a greater thread to public health due to…

The SARS-CoV-2 virus is a public health emergency. Social distancing is a key approach to slowing disease transmission. However, more evidence is needed on its efficacy, and little is known on the types of areas where it is more or less effective. We…

We conducted a challenge/rechallenge trial in which 3 alpacas were infected with Middle East respiratory syndrome coronavirus. The alpacas shed virus at challenge but were refractory to further shedding at rechallenge on day 21. The trial indicates…
