Āsana for Back, Hips and Legs to Prevent Musculoskeletal Disorders among Dental Professionals: In-Office Yóga Protocol

Abstract: Dental professionals are exposed to significant unavoidable physical stress, and theoretical ergonomic recommendations for a sitting workplace are inapplicable in many dental activities. Work-related musculoskeletal disorders (WMSDs) represent a serious health problem among dental professionals (prevalence: 64–93%), showing involvement of 34–60% for the low back and 15–25% for the hips. Muscle stress; prolonged sitting; forward bending and twisting of the torso and head; unbala...

Inhibition of Urease, a Ni-Enzyme: The Reactivity of a Key Thiol With Mono- and Di-Substituted Catechols Elucidated by Kinetic, Structural, and Theoretical Studies

The inhibition of urease from Sporosarcina pasteurii (SPU) and Canavalia ensiformis (jack bean, JBU) by a class of six aromatic poly-hydroxylated molecules, namely mono- and dimethyl-substituted catechols, was investigated on the basis of the inhibitory efficiency of the catechol scaffold. The aim was to probe the key step of a mechanism proposed for the inhibition of SPU by catechol, namely the sulfanyl radical attack on the aromatic ring, as well as to obtain critical information on the eff...

Il valore del rischio nell’esperienza educativa all’aperto = The Value of Risk in the Outdoor Educational Experience

A partire dalla riflessione fenomenologica, il contributo affronta il tema del rischio come aspetto inscindibile dalla natura umana, essendo l’incertezza e la precarietà parti costitutive dell’esistenza stessa. Riflettendo sul concetto di rischio benefico e sul ruolo che dovrebbero avere l’educazione, gli adulti e la società intera nei confronti del rischio, si mette in evidenza come, al contrario, la protezione eccessiva generi nel lungo periodo effetti negativi. Supportano tale convinzione ...
