Effects of 5G radiofrequency electromagnetic radiation on indicators of vitality and DNA integrity of in vitro exposed boar semen.

The effects of radiofrequency electromagnetic radiation (RF-EMR) on semen quality have been in the spotlight in recent years, though research results to date have been contradictory. The effects of RF-EMR amongst others depend upon frequency, and there is currently no literature concerning the influence of 5G frequencies on both DNA integrity and spermatozoa vitality in males. The aim of this study was to investigate the effect of 5G RF-EMR on sperm membrane integrity, mitochondrial potential, and DNA integrity of in vitro exposed semen of breeding boars.

The influence of exogenous melatonin on antioxidative status in seminal plasma and spermatozoa in French Alpine bucks during the nonbreeding season.

Research data regarding exogenous melatonin effects on buck semen antioxidative status during the breeding and nonbreeding seasons are scarce or missing. The aim of this study was to investigate the effect of melatonin implants on the activity and ratios of antioxidative enzymes and on malondialdehyde concentrations in the seminal plasma and spermatozoa of French Alpine bucks during the 3 mo of the nonbreeding season. Two groups of randomly assigned bucks were either treated with melatonin (n = 6) or served as controls (n = 6).

Exogenous melatonin influences distribution of French Alpine buck spermatozoa in morphometrically distinct subpopulations during the non-breeding season.

The aim of this study was to establish subpopulations of spermatozoa in bucks using the principal component (PC) and cluster analysis according to morphometric head and tail variables, and to determine differences in proportions of subpopulations between exogenous melatonin-treated and control bucks. The bucks (n = 12) were assigned to two groups comprising six bucks each. By the end of March, four melatonin implants were inserted in the bucks in the experimental group.

Monitoring of libido and semen quality parameters in melatonin-treated French alpine bucks during the non-breeding season.

The aim of this study was to investigate the effects of exogenous melatonin on libido and semen quality parameters in bucks during the non-breeding season. Twelve bucks of the French alpine breed from 1.5 to 4 years of age were assigned into melatonin (MG) and control (CG) groups, with 6 bucks in each group.

The onset of puberty in Cameroon Dwarf goats kept as pets in northwestern Croatia.

The aim of this study was to determine onset of puberty in Cameroon Dwarf goats (CDGs) kept as pets in northwestern Croatia by determining progesterone (PGS) and insulin-like growth factor-I (IGF-I) levels in the blood by RIA methods. The first cyclic ovarian activity was estimated according to hormone profiles as determined in CDG in a moderate climate environment. Sixteen female CDG kids were kept in stables with access to pasture which provided space for exercise.

[Sequential endoscopic and laparoscopic and one-step treatment of cholecysto-choledochal calculosis. New perspectives for the surgeon].

The Authors describe 132 cases of sequential treatment of cholecysto-choledochal lithiasis by videolaparoscopic cholecystectomy after endoscopic Common Bile Duct (CBD) clearance and 3 endoscopic sphincterectomy and CBD stone extraction during laparoscopic cholecystectomy. No complications occurred during the procedure. Even though the second one is not a routine method undoubtedly represents the best solution when the surgeon meets an unexpected choledocholithiasis.

[Microcystic serous cystadenoma of the pancreas. Enucleation or regulated pancreatic resection?].

Cystic benign tumors of the pancreas are rare lesions: they represent less than 10% of all pancreatic neoplasms. We studied two cases of microcystic adenoma, one of the less common varieties, that only in the last few years has been morphologically recognized as a distinct pathological entity. Our clinical experience--though limited--made us remark some interesting features: 1) preoperative diagnostic procedures (ultrasonography and CT) may present great interpretative difficulties: in one of the cases observed, radiographic imaging demonstrated an unresectable pancreatic tumor.

[Indications for surgical and sclerosing treatment of varices of the lower limbs].

The authors consider the usefulness of sclerosing varicose veins in the lower limbs according to tournay's classic teaching, and in accordance with their basically surgical orientation, they try to classify a series of absolute indications for the surgical treatment, and a second series of analogous indications for the sclerosant treatment. Since the treatment of varicose veins does not come into effect all at once, the two methods - surgical and sclerosant - can be usefully combined.

[Etiopathogenesis and therapy of ulcers of the lower limbs].

The authors assess the pathogenic causes of leg-ulcers which all have as a common denominator chronic venous incompetence. It is vital to have a correct identification of prevention of frequent relapse as well as cure. The authors suggest their strategy of topic treatment which, despite its simplicity and economy, has never proved unsuccessful.

[Ablation of haemorrhoids by cryosurgery in high risk patients (author's transl)].

A group of 48 patients of differing age and sex, suffering from 3rd degree hemorrhoids with pulmonary, cardiac or renal disease, epilepsy or scleroderma, so that the traditional operation under general anaesthesia is contraindicated, is examined. Cryosurgical haemorrhoidectomy, without hospitalisation, under local anaesthesia of anal sphincter led in all these patients to cure verified rectoscopically 2-3 months after the operation. The postoperative course was entirely normal, with pain symptoms that were sharp in 7 cases, limited in 14.

[Cancer of the breast in pregnancy].

The Authors discuss the incidence of mammary carcinoma in the course of pregnancy and its treatment. On the strength of their own experience as well as in the light of published data, they advocate prompt and complete local and regional treatment by surgery and irradiation whenever possible. In their opinion, the concomitant pregnancy does not constitute a contraindication.
