Adiponectin and Orexin-A as a Potential Immunity Link Between Adipose Tissue and Central Nervous System

Adipose tissue (AT) is strongly associated with development and progression of immune disorders through adipokines secretion, such as adiponectin. This protein has beneficial energetic properties and is involved in inflammation and immunity processes. Three oligomers of circulating Adiponectin with different molecular weight are described: High (HMW), Medium (MMW) and Low (LMW). The HMW is the most biologically active oligomers. On binding to its receptors AdipoR1, AdipoR2, and T-cadherin, adiponectin acts on both innate and acquired immunity. The suppression of NF-kB activation and pro-inflammatory cytokine expression in macrophages is mediated by AdipoR1. AdipoR2 mediates polarization of …

Non-Rapid Eye Movement Sleep Parasomnias and Migraine: A Role of Orexinergic Projections

Introduction: Sleep and migraine share a common pathophysiological substrate, although the underlying mechanisms are unknown. The serotonergic and orexinergic systems are both involved in the regulation of sleep/wake cycle, and numerous studies show that both are involved in the migraine etiopathogenesis. These two systems are anatomically and functionally interconnected. Our hypothesis is that in migraine a dysfunction of orexinergic projections on the median raphe (MR) nuclei, interfering with serotonergic regulation, may cause Non-Rapid Eye Movement parasomnias, such as somnambulism. Hypothesis/theory: Acting on the serotonergic neurons of the raphe nuclei, the dysfunction of orexinergic…

Neuropeptides’ Hypothalamic Regulation of Sleep Control in Children Affected by Functional Non-Retentive Fecal Incontinence

Functional non-retentive fecal incontinence (FNRFI) is a common problem in pediatric age. FNRFI is defined as unintended loss of stool in a 4-year-old or older child after organic causes have been excluded. FNRFI tends to affects up to 3% of children older than 4 years, with males being affected more frequently than females. Clinically, children affected by FNRFI have normal intestinal movements and stool consistency. Literature data show that children with fecal incontinence have increased levels of separation anxiety, specific phobias, general anxiety, attention-deficit/hyperactivity disorder (ADHD), and oppositional defiant disorder. In terms of possible relationship between incontinence…

A brief anatomo-surgical dissection guide to human mediastinal anatomy: results of the collaboration between the University of Palermo and the University of Malta.

In the summer of 2017, thanks to an agreement between the University of Malta and the University of Palermo, a group of students from the University of Palermo, who had already taken the anatomy exams and had a good knowledge of English, went for a 4 week period to the University of Malta to follow a dissection course . The students dissected skin, the sternum, the vessels, the nerves, analyzed the pericardium, the lungs and all the mediastinal organs. This work proves to be a small dissection guide for young medical students who want to learn the basics of dissection and the relevant topographical anatomy. The students were selected by the University of Palermo because of the good quality …

A brief anatomo-surgical dissection guide to the human neck: results of a collaboration between the University of Palermo and the University of Malta.

The aim of this work was to offer a guide to young students and medical doctors that want to learn the bases of neck dissection. In the summer of 2017 a group of students from the University of Palermo that had already passed the Human Anatomy exams took a 4 weeks dissection course at the University of Malta Medicine is a science that requires both a practical and theoretical approach, and the last one, unfortunately, often is not valued by our University. Studying Human Anatomy, which is the basis for a doctor's education, exclusively through books and atlases, is indeed partially lacking. For this reason a group of students from the University of Palermo have been selected, based on their…
