Evaluation of systemic inflammation in patients being weaned from mechanical ventilation

Clinics; 73 (), 2018
OBJECTIVES: The aim of this study was to evaluate systemic inflammatory factors and their relation to success or failure in a spontaneous ventilation test. METHODS: This cross-sectional study included a sample of 54 adult patients. Demographic data and clinical parameters were collected, and blood sampl...

HSP70 from the Antarctic sea urchin Sterechinus neumayeri: molecular characterization and expression in response to heat stress

Biol. Res; 51 (), 2018
Abstract Background: Heat stress proteins are implicated in stabilizing and refolding denatured proteins in vertebrates and invertebrates. Members of the Hsp70 gene family comprise the cognate heat shock protein (Hsc70) and inducible heat shock protein (Hsp70). However, the cDNA sequence and the express...

Regulation of aquaporins in plants under stress

Biol. Res; 51 (), 2018
Abstract Aquaporins (AQP) are channel proteins belonging to the Major Intrinsic Protein (MIP) superfamily that play an important role in plant water relations. The main role of aquaporins in plants is transport of water and other small neutral molecules across cellular biological membranes. AQPs have rem...

Physiological response and productivity of safflower lines under water deficit and rehydration

An. acad. bras. ciênc; 89 (4), 2017
ABSTRACT Water deficit is one of the major stresses affecting plant growth and productivity worldwide. Plants induce various morphological, physiological, biochemical and molecular changes to adapt to the changing environment. Safflower (Carthamus tinctorius L.), a potential oil producer, is highly adapt...

Photosynthetic capacity and water use efficiency in Ricinus communis (L) under drought stress in semi-humid and semi-arid areas

An. acad. bras. ciênc; 89 (4), 2017
ABSTRACT Castor bean is one of the crops with potential to provide raw material for production of oils for biodiesel. This species possess adaptive mechanisms for maintaining the water status when subjected to drought stress. A better understanding these mechanisms under field conditions can unravel the ...

Anatomical traits related to stress in high density populations of Typha angustifolia L. (Typhaceae)

Braz. j. biol; 77 (1), 2017
Abstract Some macrophytes species show a high growth potential, colonizing large areas on aquatic environments. Cattail (Typha angustifolia L.) uncontrolled growth causes several problems to human activities and local biodiversity, but this also may lead to competition and further problems for this speci...

Effects of different levels of end-expiratory pressure on hemodynamic, respiratory mechanics and systemic stress response during laparoscopic cholecystectomy

Rev. bras. anestesiol; 67 (1), 2017
Abstract Objective: General anesthesia causes reduction of functional residual capacity. And this decrease can lead to atelectasis and intrapulmonary shunting in the lung. In this study we want to evaluate the effects of 5 and 10 cmH2O PEEP levels on gas exchange, hemodynamic, respiratory mechanics and ...

Bases bioquímicas de la tolerancia al estrés osmótico en hongos fitopatógenos: el caso de Macrophomina phaseolina (Tassi) Goid
Biochemical basis of tolerance to osmotic stress in phytopathogenic fungus: The case of Macrophomina phaseolina (Tassi) Goid

Rev. argent. microbiol; 48 (4), 2016
El hongo Macrophomina phaseolina (Tassi) Goid., agente causal de la enfermedad denominada «pudrición carbonosa», provoca pérdidas significativas en la producción de cultivos como maíz, sorgo, soya y frijol en México. Este hongo, parásito facultativo, muestra amplia capacidad de adaptación a ambi...

Efecto de la adrenomedulina cerebelosa frente al estrés agudo

Invest. clín; 57 (3), 2016
La adrenomedulina (AM) es un péptido involucrado en la regulación cardiovascular. En el cerebelo, la densidad de los receptores de la AM se encuentra alterada durante la hipertensión, sugiriendo un posible papel del sistema adrenomedulinérgico cerebelar en la regulación de la presión arterial (PA)....

Schizophrenia and reelin: a model based on prenatal stress to study epigenetics, brain development and behavior

Biol. Res; 49 (), 2016
Schizophrenia is a severe psychiatric disorder that results in a significant disability for the patient. The disorder is characterized by impairment of the adaptive orchestration of actions, a cognitive function that is mainly dependent on the prefrontal cortex. This behavioral deficit, together with cel...
