PHYSICOCHEMICAL PROPERTIES AND ACCEPTANCE OF JELLY AND NECTAR OF ARAZA AND PAPAYA

The main objective of this work was to evaluate the acceptance of jelly and nectars made from araza (Eugenia stipitata Mc Vaugh) and papaya. The following percentages of araza and papaya were, respectively, used: 50:50; 40:60; 30:70 and 20:80. For both pulps and products the variables studied were: acidity, pH, total content of soluble solids. Acceptance tests were conducted for the developed products. An inverse relation was observed between the papaya proportion and the soluble solids content and titratable acidity. The jelly made with skin araza presented higher levels of soluble solids, higher pH and lower titratable acidity compared with those obtained with fruit without the peel. Higher concentrations of papaya pulp improved the acceptance of nectar and jelly in all formulations. It was observed an increased in the acceptance when using araza with skin, until levels of 45% of papaya for the jelly and 24% for the nectar. This was probably due to specific sensorial attributes of the araza skin and it is an indicator for future researches

Destacadas de soja (Glycine max (L.) merril absorção de cálcio e fósforo por raízes var. IAC-2)

This paper deals with experiments designed to study the influence of several external factors on the uptake both of Ca+² and H2PO4 - by excised soybean roots. The main conclusions are as follows: 1) Ca uptake does not follow the usual Michaelian kynetics, the evidence suggesting the operation of passive mechanism; 2) R uptake is metabolic, a single mechanism being in operation; 3) pH has a strong effect both on Ca and R absorption; 4) The use both of lower temperature (O0C) and of respiratory poisons (cyanide) inibited phosphate uptake but had no effect on calcium absorption. 5) The obsorption of Ca+2 was lowered in the presence of Mg+² but not in that of K+; nitrate ions had no detrimental or sinergistic offect on the absorption of phosphate.A absorção do cálcio e do fósforo por raízes destacadas da soja var. IAC-2 foi estudada com ajuda de traçadores. Foram verificados os efeitos da concentração iônica externa do tempo, do pH, da temperatura, da aeração e de venenos respiratórios. Os dados sugerem que a absorção do cálcio tenha se dado passivamente, sendo ativa a do fósforo. A absorção cresceu com o pH e a temperatura. Os valores das constantes de Michaelis encontrados concordam com os da literatura

Association of Nonobstructive Chronic Bronchitis with Respiratory Health Outcomes in Adults

Importance: Chronic bronchitis has been associated with cigarette smoking as well as with e-cigarette use among young adults, but the association of chronic bronchitis in persons without airflow obstruction or clinical asthma, described as nonobstructive chronic bronchitis, with respiratory health outcomes remains uncertain. Objective: To assess whether nonobstructive chronic bronchitis is associated with adverse respiratory health outcomes in adult ever smokers and never smokers. Design, Setting, and Participants: This prospective cohort study included 22325 adults without initial airflow obstruction (defined as the ratio of forced expiratory volume in the first second [FEV1] to forced vital capacity [FVC] of <0.70) or clinical asthma at baseline. The National Heart, Lung, and Blood Institute (NHLBI) Pooled Cohorts Study harmonized and pooled data from 9 US general population-based cohorts. Thus present study is based on data from 5 of these cohorts. Participants were enrolled from August 1971 through May 2007 and were followed up through December 2018. Exposures: Nonobstructive chronic bronchitis was defined by questionnaire at baseline as both cough and phlegm for at least 3 months for at least 2 consecutive years. Main Outcomes and Measures: Lung function was measured by prebronchodilator spirometry. Hospitalizations and deaths due to chronic lower respiratory disease and respiratory disease-related mortality were defined by events adjudication and administrative criteria. Models were stratified by smoking status and adjusted for anthropometric, sociodemographic, and smoking-related factors. The comparison group was participants without nonobstructive chronic bronchitis. Results: Among 22325 adults included in the analysis, mean (SD) age was 53.0 (16.3) years (range, 18.0-95.0 years), 58.2% were female, 65.9% were non-Hispanic white, and 49.6% were ever smokers. Among 11082 ever smokers with 99869 person-years of follow-up, participants with nonobstructive chronic bronchitis (300 [2.7%]) had accelerated decreases in FEV1 (4.1 mL/y; 95% CI, 2.1-6.1 mL/y) and FVC (4.7 mL/y; 95% CI, 2.2-7.2 mL/y), increased risks of chronic lower respiratory disease-related hospitalization or mortality (hazard ratio [HR], 2.2; 95% CI, 1.7-2.7), and greater respiratory disease-related (HR, 2.0; 95% CI, 1.1-3.8) and all-cause mortality (HR, 1.5; 95% CI, 1.3-1.8) compared with ever smokers without nonobstructive chronic bronchitis. Among 11243 never smokers with 120004 person-years of follow-up, participants with nonobstructive chronic bronchitis (151 [1.3%]) had greater rates of chronic lower respiratory disease-related hospitalization or mortality (HR, 3.1; 95% CI, 2.1-4.5) compared with never smokers without nonobstructive chronic bronchitis. Nonobstructive chronic bronchitis was not associated with FEV1:FVC decline or incident airflow obstruction. The presence of at least 1 of the component symptoms of nonobstructive chronic bronchitis (ie, chronic cough or phlegm), which was common in both ever smokers (11.0%) and never smokers (6.7%), was associated with adverse respiratory health outcomes. Conclusions and Relevance: The findings suggest that nonobstructive chronic bronchitis is associated with adverse respiratory health outcomes, particularly in ever smokers, and may be a high-risk phenotype suitable for risk stratification and targeted therapies

Lung function impairment and risk of incident heart failure: the NHLBI Pooled Cohorts Study

Aims: The aim is to evaluate associations of lung function impairment with risk of incident heart failure (HF). Methods and results: Data were pooled across eight US population-based cohorts that enrolled participants from 1987 to 2004. Participants with self-reported baseline cardiovascular disease were excluded. Spirometry was used to define obstructive [forced expiratory volume in 1 s/forced vital capacity (FEV1/FVC) <0.70] or restrictive (FEV1/FVC ≥0.70, FVC <80%) lung physiology. The incident HF was defined as hospitalization or death caused by HF. In a sub-set, HF events were sub-classified as HF with reduced ejection fraction (HFrEF; EF <50%) or preserved EF (HFpEF; EF ≥50%). The Fine-Gray proportional sub-distribution hazards models were adjusted for sociodemographic factors, smoking, and cardiovascular risk factors. In models of incident HF sub-types, HFrEF, HFpEF, and non-HF mortality were treated as competing risks. Among 31 677 adults, there were 3344 incident HF events over a median follow-up of 21.0 years. Of 2066 classifiable HF events, 1030 were classified as HFrEF and 1036 as HFpEF. Obstructive [adjusted hazard ratio (HR) 1.17, 95% confidence interval (CI) 1.07-1.27] and restrictive physiology (adjusted HR 1.43, 95% CI 1.27-1.62) were associated with incident HF. Obstructive and restrictive ventilatory defects were associated with HFpEF but not HFrEF. The magnitude of the association between restrictive physiology and HFpEF was similar to associations with hypertension, diabetes, and smoking. Conclusion: Lung function impairment was associated with increased risk of incident HF, and particularly incident HFpEF, independent of and to a similar extent as major known cardiovascular risk factors
