Freezing/thawing as an accelerating process of wet- and dry-aged Nellore beef.

This study aimed to evaluate the use of freezing/thawing as a way of accelerating the aging processes of beef from Nellore animals. Non-frozen (NF) or freezing/thawing (FT) strip loins were aged (for 14 and 28 days) using two systems: bone-in dry-aging (DA); boneless wet-aging (WA). FT-treated samples had greater weight losses (P < 0.

S-nitrosothiols as nitrite alternatives: Effects on residual nitrite, lipid oxidation, volatile profile, and cured color of restructured cooked ham.

This study evaluated the use of the S-nitrosothiols, S-nitroso-N-acetylcysteine (NAC-SNO) and S-nitroso-N-acetylcysteine ethyl ester (NACET-SNO), at different concentrations (25-300 mg nitrite equivalent - NEq/kg) as sodium nitrite substitutes in restructured cooked hams. The pH value and instrumental cured color were not affected by the type or amount of curing agent used. Products with 25 and 50 mg/kg ingoing nitrite had lower thiobarbituric acid-reactive substance values than those with equimolar amounts of S-nitrosothiols.

Patterns of physical activity and SARS-CoV-2 severe pneumonia: A case-control study.

Background: Regular physical activity is associated with a low risk of severe community-acquired infections. However, the hypothesis that a physical inactivity pattern is associated with a higher risk for severe COVID-19 has not been completely proven, especially with severe pneumonia.

Objective: The goal of this study was to confirm the link between physical activity patterns and severe SARS-CoV-2 pneumonia.

Application of gamma radiation in the beef texture development during accelerated aging.

This study aimed to evaluate the effects of gamma radiation (3 kGy) on the quality of post-rigor beef (M. longissimus lumborum) aged for up to 21 days at different temperatures (1, 7, and 15°C). Irradiation reduced the mesophilic and lactic acid bacteria counts, which were higher in the non-irradiated samples aged at 7 and 15°C.

Assessment of Japanese radish derivatives as nitrite substitute on the physicochemical properties, sensorial profile, and consumer acceptability of restructured cooked hams.

This study aimed to evaluate the technological and sensory properties of restructured cooked hams prepared with natural curing agents (0.5% radish powder, HRP; 3% radish juice, HRJ; and 0.5% radish pulp powder, HRPP) and with 40 and 150 mg/kg sodium nitrite (HN40 and HN150, respectively).

Quality of honeys from different botanical origins.

Botanical origin is one of the principal factors influencing the composition and quality of honey. This study aimed to evaluate different single-flower (assa-peixe, coffee, eucalyptus, laranjeira, and vassourinha), polyfloral (silvestre), extrafloral (sugarcane), and honeydew (bracatinga) honeys with regard to their chemical, physicochemical, and physical properties; rheological behavior; bioactive compounds; and antioxidant activity. In addition, we assessed their sensory characteristics using the acceptance test and the check-all-that-apply test (CATA).

Magnesium supplementation and preeclampsia in low-income pregnant women - a randomized double-blind clinical trial.

Background: Preeclampsia is the major cause of maternal morbidity and mortality in developing countries. Magnesium sulfate is considered first-line therapy against eclampsia and magnesium deficiency in pregnancy has been associated with unfavourable perinatal outcomes. However there are doubts if magnesium supplementation during pregnancy can previne preeclampsia especially in population with high nutritional risk.

Visceral Adipose Tissue Depth in Early Pregnancy and Gestational Diabetes Mellitus - a Cohort Study.

Some studies have suggested that abdominal visceral adipose tissue depth (VAD) measured by ultrasound in early pregnancy, may predict the future onset of gestational diabetes mellitus (GDM). Wheter this is true, independent of pre-pregnancy body mass index (BMI), has been debated, leading the current study. A prospective cohort study was completed, in which VAD was measured at around 14 weeks' gestation.

The BRAzil MAGnesium (BRAMAG) trial: a randomized clinical trial of oral magnesium supplementation in pregnancy for the prevention of preterm birth and perinatal and maternal morbidity.

Background: Preterm birth is the leading cause of infant mortality globally, including Brazil. We will evaluate whether oral magnesium citrate reduces the risk of placental dysfunction and its negative consequences for both the fetus and mother, which, in turn, should reduce the need for indicated preterm delivery.

Methods/design: We will complete a multicenter, randomized double-blind clinical trial comparing oral magnesium citrate 150 mg twice daily (n = 2000 women) to matched placebo (n = 1000 women), starting at 121/7 to 206/7 weeks gestation and continued until delivery.

Mental health and work: meanings and limits of theoretical models.

This text is a revision of the most important theoretical approaches that fundament the studies about Mental Health and Work, pointing to the basic concepts, categories of analyses and respective limits. The objective is to underline some conceptions about the theme, in the attempt to contribute with a way to face the problems, questions and difficulties imposed by the construction of this object of study. Thus, the text is based on the critical review of theoretical paradigms that predominate in studies about Mental Health and Work.
