Fisiología respiratoria: fisiología del surfactante pulmonar

El proceso de respiración y el intercambio gaseoso requiere la interacción de variadas fuerzas en los distintos tejidos y órganos involucrados. La tensión superficial a nivel alveolar provocaría colapso de dichas estructuras de no ser por las características del surfactant...

Mobilization of seed storage proteins is crucial to high vigor in common bean seeds

Ciênc. rural (Online); 52 (2), 2022
Seed germination is a complex process controlled by many factors, in which physical and biochemical mechanisms are involved and the mobilization of reserves is crucial for this process to occur. Although, seed reserve mobilization is usually thought to be a post-germination process, seed reserve proteins...

Biomarcadores en tuberculosis

Resumen Los métodos diagnósticos clásicos para la tuberculosis son de baja sensibilidad o son muy lentos en la obtención de resultados (baciloscopía, cultivo de Koch). De ahí nace la necesidad de nuevos métodos diagnósticos para esta enfermedad. Los biomarcadores surgen como una opción a esta pr...

Características fisicoquímicas, mecánicas y sensoriales de salchichas secas tipo cabanossi elaboradas con carne de llama (Lama glama) y cerdo (Sus scrofa domestica)

Rev. chil. nutr; 47 (3), 2020
RESUMEN Se estableció la caracterización de salchichas secas tipo cabanossi con carne de llama, cerdo y muestras comerciales mediante un análisis proximal (contenidos de grasa: 18,6 a 29,6% y proteína: 19,4 a 36,2%), color (C*: 15,8 a 33,7), actividad de agua (0,770 a 0,960), pH (5,2 a 6,5) y propied...

Chemical characterization, antimicrobial and antioxidant activity of sugar-apple (Annona squamosa L. ) pulp extract

Rev. chil. nutr; 47 (2), 2020
Synthetic preservatives are widely present in processed foods, but most of them have carcinogenic potential, requiring the development of new natural alternatives such as fruit extracts, for microbial control. The objective of the study was to evaluate the chemical characterization, antioxidant, and anti...

Physicochemical and nutritional aspects of babassu coconut almond and oil (Orbignya phalerata Mart. )

Rev. chil. nutr; 47 (1), 2020
The potential use of babassu (Orbignya phalerata Mart.) in several activities is large. In view of these facts, this study aimed to determine the physicochemical composition of the babassu almond (OpAM) and evaluate the chemical, physical and physicochemical aspects of babassu coconut oil isolated by dif...

Protein structure of the venom in nine species of snake: from bio-compounds to possible healing agents

Braz. j. med. biol. res; 53 (1), 2020
Due to its various structures in bio-compounds, snake venom is the indisputable result of evolutionary stages of molecules with an increasingly complex structure, high specificity, and of great importance for medicine because of their potential. The present study proposed an underpinning examination of v...

Comparison of protein profiles of the pellicle, gingival crevicular fluid, and saliva: possible origin of pellicle proteins

Biol. Res; 53 (), 2020
BACKGROUND: The pellicle, the acellular organic material deposited on the surface of tooth enamel, has been thought to be derived from saliva. In this study, protein compositions of the pellicle, gingival crevicular fluid, and saliva collected from healthy adults were compared to elucidate the origin of ...

Leucine-rich glioma inactivated 3: a novel keratinocyte-derived melanogenic cytokine in vitiligo patients

An. bras. dermatol; 94 (4), 2019
Abstract: Background: In-vitro studies showed that Leucine-rich glioma inactivated 3 (LGI3) is a keratinocyte-derived cytokine that stimulates melanin synthesis and is increased after ultra violet B (UVB) irradiation. So, we postulated that LGI3 may be involved in vitiligo aetiopathogenesis and may part...

Aspectos generales del perfil proteómico del Echinococcus granulosus

Int. j. morphol; 37 (2), 2019
La información disponible referente a las características proteómicas del E. granulosus es escasa (no supera los 50 estudios publicados); y nos parece que la identificación proteómica, podría mejorar la comprensión de algunas características bioquímicas e inmunológicas de la Equinococosis Quís...
