ABSTRACT
Abstract: School Active Breaks are short bouts of physical activity (5-15 minutes) conducted by appropriately trained teachers and delivered during or between curricular lessons. They are a good strategy to counteract sedentary behaviors, and a growing body of evidence shows that they can represent also a tool to promote and improve health, school wellbeing and academic achievements. On 19 February 2022, the Working Group on Movement Sciences for Health of the Italian Society of Hygiene, Preventive Medicine and Public Health organized an Awareness Day on the effectiveness, usefulness and feasibility of School Active Breaks, opened to teachers, educators, school leaders, pediatricians, personnel from Departments of Prevention and Public Health and Health Policy-makers. During the event, the testimonies about the experiences already carried out in Italy showed that School Active Breaks are an effective intervention that each school can easily include in its educational offer and apply in any context.

Cytochrome P450 (CYP) 1B1 and CYP2J have been studied in various mammals, but not in pig. The sequences encoding pig CYP1B1 and CYP2J34 were isolated from liver cDNA by RACE and sequenced. The open reading frames of pig CYP1B1 showed a higher sequence homology to bovine 1B1 (89%) than to dog 1B1 (88%) or to human 1B1 (85%). On the other hand, the coding sequence of pig CYP2J34 showed a similar homology (83-85%) to CYP2J of these species. From the substrate recognition sites (SRS 1-6) analysis of the deduced proteins, it was found that the porcine CYP1B1, unlike CYP2J34, completely shared the six SRS with the bovine counterpart. RT-PCR analysis of CYP1B1 and CYP2J34 expression in ten porcine tissues revealed that CYP1B1 was principally expressed in adrenal gland, whereas CYP2J34 was predominantly expressed in small intestine. These results further support the pig as an useful model for human.
