Milk metagenomics and cheese-making properties as affected by indoor farming and summer highland grazing.

The study of the complex relationships between milk metagenomics and milk composition and cheese-making efficiency as affected by indoor farming and summer highland grazing was the aim of the present work. The experimental design considered monthly sampling (over 5 mo) of the milk produced by 12 Brown Swiss cows divided into 2 groups: the first remained on a lowland indoor farm from June to October, and the second was moved to highland pastures in July and then returned to the lowland farm in September. The resulting 60 milk samples (2 kg each) were used to analyze milk composition, milk coagulation, curd firming, and syneresis processes, and to make individual model cheeses to measure cheese yields and nutrient recoveries in the cheese.

COVID-19: Measures to prevent hospital contagion. What do urologists need to know?

A new outbreak of respiratory infection caused by the novel coronavirus in late December 2019 in China caused standards of medical care to change not only for related areas but for the entire healthcare system, and when the WHO declared COVID-19 a pandemic new strategies of patient care had to be defined initially to optimize resources to confront the pandemic and then to protect healthcare personnel. As urologists, we must be involved in these new standards, since without an effective vaccine the risk of contagion is high; thus, the purpose of this review is to have orientation on the measures urologists should take in their everyday clinical practice.

VAPB ER-Aggregates, A Possible New Biomarker in ALS Pathology.

A point mutation (P56S) in the gene-encoding vesicle-associated membrane-protein-associated protein B (VAPB) leads to an autosomal-dominant form of amyotrophic lateral sclerosis (ALS), classified as ALS-8. The mutant VAPB is characterized by ER-associated aggregates that lead to a complete reorganization of ER structures. Growing evidences suggest VAPB involvement in ALS pathomechanisms.

Intrahepatic bile duct primary cilia in biliary atresia.

Aim: The etiopathogenesis of non-syndromic biliary atresia (BA) is obscure. The primary aim was to investigate intrahepatic bile duct cilia (IHBC) in BA at diagnosis and its correlation with clinical outcome. The secondary aim was to analyze IHBC in routine paraffin-embedded liver biopsies using conventional scanning electron microscopy (SEM).

Organ-specific antibodies in LADA patients for the prediction of insulin dependence.

Aim Of The Study: The aim of the present study was to define the frequency of organ-specific and non-organ-specific autoantibodies in a cohort of Latent Autoimmune Diabetes in Adults (LADA) patients and to test whether multiple antibodies positivity could be a predictor of early insulin dependence.

Materials And Methods: We enrolled 210 LADA and 210 type 2 diabetes mellitus (T2D) patients. In all subjects anti-islet antigen-2 (IA-2Ab), anti-thyroperoxidase (TPOAb), anti-zinc transporter 8 (ZnT8Ab), anti-nuclear (ANA), anti-parietal cell (APCA), anti-smooth muscle (ASMA), anti-mitochondrial (AMA), anti-liver kidney microsomes (LKM), and anti-reticulin (ARA) circulating antibodies were assessed.

[Polymyalgia rheumatica and aortic involvement].

Polymyalgia rheumatica (PMR) is an inflammatory disorder that affects people over 50 years of age, characterized by pain and stiffness in the neck and shoulder and pelvic girdles. PMR may occur as an isolated condition or concomitantly with giant cell arteritis. Similar to other inflammatory rheumatic disorders, PMR is associated with an increased cardiovascular risk due to inflammatory changes in large arterial vessels, which result in an increased chance of developing aneurysms and dissections.

Feasibility, reproducibility, and reliability for the T*2 iron evaluation at 3 T in comparison with 1.5 T.

This study aimed to determine the feasibility, reproducibility, and reliability of the multiecho T*(2) Magnetic resonance imaging technique at 3 T for myocardial and liver iron burden quantification and the relationship between T*(2) values at 3 and 1.5 T. Thirty-eight transfusion-dependent patients and 20 healthy subjects were studied.

Mendelian breeding units versus standard sampling strategies: Mitochondrial DNA variation in southwest Sardinia.

We report a sampling strategy based on Mendelian Breeding Units (MBUs), representing an interbreeding group of individuals sharing a common gene pool. The identification of MBUs is crucial for case-control experimental design in association studies. The aim of this work was to evaluate the possible existence of bias in terms of genetic variability and haplogroup frequencies in the MBU sample, due to severe sample selection.

Preliminary evaluation of particle systems visualization on the skin surface by scanning electron microscopy and transparency profilometry.

Background: There is a rising debate concerning the possible side effects arising from the use of particles at nanosize since the production of nanomaterials is increasing worldwide. Nanoparticles are able to enter the body through the skin, lungs or intestinal tract, depositing in several organs, and the risk associated with exposure to them, the routes of entry and the molecular mechanisms of any cytotoxicity need to be well understood. The aim of this work was to evaluate the suitability of skin replica as a method to study the colloidal systems visualization and distribution on skin surface.

Number of autoantibodies and HLA genotype, more than high titers of glutamic acid decarboxylase autoantibodies, predict insulin dependence in latent autoimmune diabetes of adults.

Objective: In latent autoimmune diabetes of adults (LADA), the progression into insulin-dependent diabetes is usually faster than in type 2 diabetes (T2D) but the factors influencing this progression are not completely known. In this study, we searched for sensitive markers associated with early development of insulin dependence.

Design: The screening of 5568 T2D patients for glutamic acid decarboxylase autoantibodies (GAD65Ab) identified 276 LADA patients (M=131; F=145) and in 251 of them, tyrosine phosphatase-2 (IA-2Ab) and thyroperoxidase autoantibodies (TPOAbs), some clinical features and genotype variation of the main type 1 diabetes (T1D) disease susceptibility loci (HLA-DRB1 and HLA-DQB1) were analyzed.

[Severe hypertriglyceridemia without organ complications in an alcoholic non-diabetic patient].

A case report of a non-diabetic alcoholic patient (ethanol intake >220 g/d) who experienced severe hypertriglyceridemia (12.679 mg/dL) without pancreatitis or detectable genetic factors responsible for severe dyslipidemia is described. Following the normalization of triglyceride and cholesterol levels, through lipid-free parenteral nutrition therapy, a regimen of alcohol withdrawal and a well-balanced diet with less than 10% saturated fat maintained a normal lipid profile without requiring any lipid-lowering drug.

Role of protein in cosmetics.

Many authors recognize the beneficial effects of using protein-rich substances in formulations of various topical applications. Proteins quickly were considered useful ingredients for creating a suitable environment for healthy skin and hair because of their ability to bind water with the horny layer of skin and its annexes. Most protein derivatives that are used for cosmetic purposes are obtained from simple proteins, whereas conjugated proteins are used far less frequently.

Therapy expectations and physical comorbidity affect quality of life in chronic hepatitis C virus infection.

Unlabelled: Hepatitis C virus (HCV) infection is associated with a significant reduction of health related quality of life (QOL), the causes and mechanisms of which are still unknown. To explore whether treatment history could affect QOL, we examined patients with detectable HCV viraemia who had a different therapeutic background. Two hundred sixty-four consecutive subjects with chronic HCV infection and detectable viraemia were enrolled.

Background: The Chronic Liver Disease Questionnaire is a specific health-related quality of life assessment designed for patients with liver diseases.

Aim: The aim of this paper is to report on the validity, reliability and sensitivity to change of the Italian version (Chronic Liver Disease Questionnaire-I) in subjects with HCV infection.

Subjects: The Chronic Liver Disease Questionnaire-I was administered to 350 subjects with HCV infection together with the World Health Organization Quality of Life Assessment, abbreviated version, a generic quality of life assessment.

[Cystic fibrosis in adults].

In the last two decades the life expectancy of patients with cystic fibrosis (CF) has improved enormously: it is now estimated at around 30 years, but some patients reach an older age and one third of all patients with CF currently reach adulthood. Once considered a pediatric disease, CF now is a disease of adults too. As a consequence, internists must be highly knowledgeable about all the clinical patterns of this multifarious disease, must be better qualified to recognize its complications and must be highly trained to treat them.

The Trp64Arg beta3-adrenergic receptor amino acid variant confers increased sensitivity to the pressor effects of noradrenaline in Sardinian subjects.

The beta(3)-adrenergic receptor (beta(3)AR) plays a critical role in lipid metabolism, and thus alterations in its function may be involved in the metabolic syndrome. Indeed, we have found previously that the Trp64Arg amino acid variant of the beta(3)AR is associated with hypertension and higher serum triacylglycerol levels in the Sardinian population. The aim of the present study was to evaluate the effect of the Trp64Arg beta(3)AR variant on the regulation of triacylglycerol levels and blood pressure during the exogenous infusion of noradrenaline.
