The pharmacological effect of opioids originates, at the cellular level, by their interaction with the μ-opioid receptor (mOR) resulting in the regulation of voltage-gated Ca2+ channels and inwardly rectifying K+ channels that ultimately modulate the synaptic transmission. Recently, an alternative six trans-membrane helix isoform of mOR, (6TM-mOR) has been identified, but its function and signa...

Any work activity performed at elevations over 3,000 m above sea level is considered as work at high altitude. The changing environmental conditions result in an adaptation of the human organism, mainly due to a reduced partial pressure of oxygen in the air and a proportional decrease in barometric pressure. We carried out a systematic review of the scientific literature in this field so as to ...

Analysis of the response to corticosteroid therapy in a personal series of 8 consecutive cases of dermatomyositis in childhood shows that there are advantages in a moderate dosage, short-term treatment schedule, with gradual tapering of the dosage as soon as there is clinical improvement without waiting for full remission, and in trying to stop steroid therapy within six months rather than foll...

BACKGROUND Even minor abnormalities of early child development may have dramatic long term consequences. Accurate prevalence rates for a range of developmental impairments have been difficult to establish. Since related studies have used different methodological approaches, direct comparisons of the prevalence of developmental delays are difficult. The understanding of the key factors affecting...
