This study presents a novel and efficient method for the extraction of Al, Ca, Cr, Cu, K, Mg, Mn, and Zn in vegetable oil samples using a Natural Deep Eutectic Solvent (NADES) as an extractor combined with microwave radiation (MW) in an emulsion system. The NADES prepared with choline chloride:oxalic acid:water (1:1:4 molar ratio) provided a high extraction rate using 5.0 mL of the sample, 1.

Introduction: Housing is one of the main supports needed to guarantee community life of people who had long-term psychiatric hospitalizations. In Argentina, housing support experiences have been developed for decades, although their systematization is scarce. The objective of this paper is to describe three housing support experiences developed in the province of Buenos Aires, Argentina, which have continuity over time for more than 20 years.

Background: Glycogen Synthase Kinase-3 beta (GSK-3β) regulates diverse cell functions including metabolic activity, signaling and structural proteins. GSK-3β phosphorylates target pro-oncogenes and regulates programmed cell death-ligand 1 (PD-L1). This study investigated the correlation between GSK-3β expression and clinically relevant molecular features of lung adenocarcinoma (PDL1 score, PTEN expression and driver mutations).

Background: Chronic hepatitis C(CHC) staging is important for therapeutic decision-making. Identification of noninvasive markers can provide alternatives to liver biopsy.

Aim: To assess the value of APRI and FIB4 for CHC fibrosis staging in a cohort of nonselected outpatients from a referral center in Sao Paulo, Brazil.

Context: Due to its good correlation to glycemic clamp, HOMA-IR has been widely utilized as insulin resistance index in clinical and epidemiological studies involving non-alcoholic fatty liver disease carriers. However, values used for this parameter have shown large variability.

Objective: To identify the HOMA-IR cut value that best distinguishes non-diabetic non-alcoholic fatty liver disease patients from a control group.

Context: Experimental and clinical studies suggest that LOLA may have a favorable influence on hepatic encephalopathy due to the effect on the reduction of ammonia, and improvement of the symptoms and laboratory findings.

Objectives: To evaluate and to critically analyze the efficacy and/or effectiveness results of the use of LOLA when compared to placebo in the treatment of hepatic encephalopathy.

Data Sources: LILACS, SciELO, MEDLINE, PubMed database and Cochrane Collaboration Register of Controlled Trials were searched from 1966 to September of 2006.

The introduction of highly active antiretroviral therapy (HAART) for the treatment of acquired immunodeficiency syndrome (AIDS) has resulted in greater survival of patients infected with the human immunodeficiency virus (HIV). However, the use of these drugs has been associated with lipodystrophic syndrome (LS), which is characterized by metabolic alterations (dyslipidemia, insulin resistance, diabetes, and lactic acidosis) and abnormal corporal fat distribution. Clinically, LS may manifest as three different forms: lipohipertrophy (accumulation of fat in the central part of the body), lipoatrophy (loss of fat in the extremities, face and buttocks) and mixed (lipohipertrophy + lipoatrophy).

A wide variety of opportunistic pathogens has been detected in the tubing supplying water to odontological equipment, in special in the biofilm lining of these tubes. Among these pathogens, Pseudomonas aeruginosa, one of the leading causes of nosocomial infections, is frequently found in water lines supplying dental units. In the present work, 160 samples of water, and 200 fomite samples from forty dental units were collected in the city of Barretos, State of São Paulo, Brazil and evaluated between January and July, 2005.

Introduction: The main extra-hepatic manifestation of hepatitis C is mixed cryoglobulinemia (MC). The aim of this study was to evaluate its prevalence among patients with chronic hepatitis C (CHC), to correlate its presence to host and virological variables and to the response to combined therapy with interferon-alpha and ribavirin.

Casuistic And Methods: 202 CHC naive patients (136 with chronic hepatitis and 66 with cirrhosis) were consecutively evaluated for the presence of cryoglobulins.

The combined therapy with interferon alfa plus ribavirin (INF+RBV) is considered the most appropriate treatment for patients with chronic hepatitis C virus genotypes 2 and 3 in Brazil. However, wide variations in the rates of sustained viral response (SVR) have been reported among such patients. We evaluated, retrospectively, factors associated with SVR in subjects with chronic hepatitis C virus genotypes 2 and 3 and that received medication from the Health Secretariat of the state of São Paulo.

Background: The 13C-methacetin breath test is a non-invasive method to evaluate hepatic microsomal function that allows a quantitative assessment of the functional hepatic mass.

Aim: To evaluate the clinical usefulness of the 13C-methacetin breath test in patients with hepatitis C chronic liver disease.

Patients And Methods: Seventy eight patients with chronic hepatitis C and 13 matched healthy controls were studied.

Purpose: To explore the caregiving role of nonprofessional caregivers of patients with chronic pain.

Method: Descriptive study of 30 caregivers.

Findings: Twenty-eight (93%) caregivers demonstrated 1 to 6 defining characteristics of caregiver role strain, and 2 (7%) had at least two factors of risk for caregiver role strain.
