Decrease in blood donation rates in Japan: a time series analysis

Rev. bras. epidemiol; 23 (), 2020
ABSTRACT: Objective: To clarify that one of the causes for the decrease in blood donation (BD) rates was the introduction of the 400 ml BD program in 1986. Method: BP rates were monitored over 48 years (1965-2012) and were divided into pre- and post-intervention periods prior to analysis. An interrup...

Comparison between enzyme-linked immunosorbent assay and indirect immunofluorescence for detection of antineutrophil cytoplasmic antibodies

ABSTRACT Objective To evaluate the performance of enzyme-linked immunosorbent assay and indirect immunofluorescence methods for the detection of antineutrophil cytoplasmic antibodies in a routine clinical laboratory setting. Methods A total of 227 samples were tested by indirect immunofluorescence an...

Correlation between nutritional assessment and oxidative stress in candidates for liver transplant

ABSTRACT Objective To evaluate the oxidative profile, nutritional status and food intake (caloric value; macronutrients; vitamins A, E and C; and zinc), and to correlate oxidative stress with nutritional status in patients who were candidates for liver transplant. Methods This is a cross-sectional, a...

Physiological profile of adult male long-distance trail runners: variations according to competitive level (national or regional)

ABSTRACT Objective To describe and identify the importance of different indicators of the aerobic and anaerobic fitness of male ultra-trail runners according to their level of participation (regional or national). Methods Forty-four male ultra-trail runners were assessed (36.5±7.2 years). They were ...

Reduction of oxidative stress improves insulin signaling in cardiac tissue of obese mice

ABSTRACT Objective To evaluate the effects of oxidative stress on insulin signaling in cardiac tissue of obese mice. Methods Thirty Swiss mice were equally divided (n=10) into three groups: Control Group, Obese Group, and Obese Group Treated with N-acetylcysteine. After obesity and insulin resistance w...

Regulatory T cells isolated from endometriotic peritoneal fluid express a different number of Toll-like receptors

ABSTRACT Objective To analyze and compare the expression of Toll-like receptors by regulatory T cells present in the peritoneal fluid of patients with and without endometriosis. Methods Regulatory T cells were isolated from peritoneal fluid of women with and without endometriosis, collected during su...

Prevalence and intensity of pain during diagnostic hysteroscopy in women attending an infertility clinic: analysis of 489 cases

ABSTRACT Objective To investigate the prevalence and intensity of pain perception during diagnostic hysteroscopy in women and potential related factors. Methods A total of 489 women were investigated at an infertility clinic. Fluid diagnostic hysteroscopy was performed without analgesia or anesthesia...

Evaluation of Head Computed Tomography Assessment of Brain Swelling after Acute Traumatic Brain Injury: A Pilot study

Arq. bras. neurocir; 38 (4), 2019
Objective To evaluate the interobserver reliability of a new scale created for quantitatively assessing brain swelling in traumatic brain injury (TBI) patients using the computed tomography (CT) findings in three levels. Methods Computed tomography scans of severe head injury patients were randomly selec...

Comparison of cerebrospinal fluid lactate with physical, cytological, and other biochemical characteristics as prognostic factors in acute bacterial meningitis

Arq. neuropsiquiatr; 77 (12), 2019
ABSTRACT Bacterial meningitis (BM) is associated with a high morbidity and mortality. Cerebrospinal fluid (CSF) lactate may be used as a prognostic marker of this condition. We hypothesized that CSF lactate levels would remain elevated in participants who died of acute BM compared with those who recovere...

Effects of intra-dentate gyrus microinjection of myokine irisin on long-term potentiation in male rats

Arq. neuropsiquiatr; 77 (12), 2019
ABSTRACT Induction of long-term potentiation (LTP) increases the storage capacity of synapses in the hippocampal dentate gyrus (DG). Irisin is a myokine generated from FNDC5 (a gene precursor) during exercise. Although intra-cornu ammonis 1 administration of irisin fortifies LTP in mice with Alzheimer's ...
