Evaluation of short-term face rejuvenation effects of non-ablative bipolar radiofrequency treatment performed by Med-RF device.

Objective: Skin laxity and wrinkling are common signs of the aging process. This physiological condition of the skin is often accompanied by psychological and social concerns, especially for females, entailing considerable expenses for cosmetics and pharmaceuticals to cease or slow down its advancement. The objective of this study was to evaluate the short-term impact of a new non-ablative radiofrequency device available in the skin face cosmetic field.

Machine Perfusions in Liver Transplantation: The Evidence-Based Position Paper of the Italian Society of Organ and Tissue Transplantation.

The use of machine perfusion (MP) in liver transplantation (LT) is spreading worldwide. However, its efficacy has not been demonstrated, and its proper clinical use has far to go to be widely implemented. The Società Italiana Trapianti d'Organo (SITO) promoted the development of an evidence-based position paper.

Clinical updating study at 3 years on 278 patients treated by modern artificial hair implant technique (automatic biofibre®).

In this study, we report our multicentric experience of synthetic medical certified polyamide hair implants in male androgenetic, female menopausal, and chronic alopecia. Biofibre hair implantation was performed by means of a standardized, mini-invasive technique followed by regular postoperative care along 3 years. From May 2015, 278 patients were enrolled and 253 completed the trial; 202 men (79.

Excess melanoma incidence in a cohort exposed to high levels of environmental selenium.

Epidemiological studies on the relation between selenium and human cancer have yielded strongly conflicting results. Prompted by the observation of a positive association between selenium intake and site-specific cancers, including melanoma, in a large cohort of nurses, we studied the 11-year melanoma incidence in an Italian cohort that consumed unusually high levels of inorganic selenium in tap water from 1975 to 1985. The setting was Reggio Emilia, an Italian municipality that provided a natural experiment relating to intake of high levels of inorganic selenium.

Cancer mortality in a residential cohort exposed to environmental selenium through drinking water.

Cancer mortality from 1986 to 1992 was examined in a cohort of 4419 individuals who had been residing in an area of the municipality of Reggio Emilia, northern Italy, where tap water with unusually high selenium content was accidentally supplied. Mortality for all cancers was not significantly different, both in males and in females, from that expected using death rates in the remaining municipal population as standard rates. No significant difference in mortality for site-specific cancers was observed in males, while in females a higher mortality for malignancies of the lymphatic-hematopoietic tissue overall considered and for non-Hodgkin's lymphoma was detected.

Zinc, copper, and zinc- or copper-dependent enzymes in human hypertension.

Imbalance of zinc and copper status has been hypothesized in human hypertension. A case-control study was carried out to elucidate the possible relationship between zinc and copper status and essential hypertension. Thirty-one subjects affected by mild stable hypertension, pharmacologically untreated, were investigated together with 31 normotensive controls individually matched for sex, age, and smoking habits.

Cardiac metastasis of rectal adenocarcinoma. Surgical treatment.

The authors report a case of cardiac metastasis of a rectal adenocarcinoma that infiltrated the right ventricle and partially obstructed its outflow tract. Surgical treatment was performed because of syncopal attacks. The differential diagnosis between organized thrombi and intracardiac tumor is considered.

Oral magnesium supplementation improves fetal circulation.

It is well known that pregnancy is a condition in which plasma magnesium falls because of accumulation of the ion in the placenta and fetus. Magnesium (Mg) is therefore widely given as a supplement during pregnancy, particularly in cases of preterm labour. In our experience, the combination of oral Mg (magnesium pyrrolidone carboxylic acid) at a dose of 360 mg/day with conventional ritodrine treatment allows a reduction in ritodrine dosage, accompanied by a significant reduction in side effects.

Sperm retrieval for direct intraperitoneal insemination in a diabetic with retrograde ejaculation. A case report.

Retrograde ejaculation is an uncommon form of male infertility. It may occur in diabetics from neuropathy involving the sympathetic fibers innervating the bladder neck. Treatment of infertility in these cases is with artificial homologous insemination.

Cell proliferation, cell death and aging.

An integrated view of the processes which most likely play a critical role in the aging process at the cellular level is proposed. Cells are continuously exposed to a variety of internal and external stressors, potentially dangerous for the maintenance of the functional integrity of the cell (UV and gamma radiation, heat, oxygen free radicals, glucose, bacteria, viruses). In the course of evolution a number of mechanisms [DNA repair, production of heat shock and other stress proteins, enzymatic and non-enzymatic antioxidant defence systems, poly(ADP-ribose) polymerase activation] have emerged which allow the cell to cope with such a variety of potentially harmful agents.
