Morphological and morphometric study of the superior vestibular nerve trunk in guinea pigs.

The guinea pig has been chosen as a research model for otologic or neuropathic studies due to the relative ease of the cochlea, cochlear nerve, and vestibular nerve dissection. Little data have been reported on the normality of these nerves. The vestibular nerve is composed of the superior vestibular, inferior vestibular, and branch nerves.

Urgent call to action: Child rights and the state of child morbidity and mortality in Yemen.

More than 2.3 million children under the age of five in Yemen suffer from acute malnutrition. Approximately 450,000 are expected to suffer from severe acute malnutrition and may die if they do not receive urgent treatment.

The silence of the lambs: Child morbidity and mortality from malnutrition in Yemen.

More than 2.3 million children under the age of five in Yemen suffer from acute malnutrition. Approximately 450,000 are expected to suffer from severe acute malnutrition and may die if they do not receive urgent treatment.

"When night falls": Violence against women and its repercussions on children and adolescents.

Violence against women is a profound global injustice. It is a major obstacle to fulfilling the human rights of women and their children. Confined to their aggressors, women exposed to this violence have even greater difficulty in accessing support networks and care services.

Watermelon and others plant foods that trigger headache in migraine patients.

: Food is already recognized as a trigger for migraine, but its mechanism of action has not been fully clarified. There is evidence that they act on the pathogenesis of migraine, interfering with meningeal inflammation, vasodilation and cerebral glucose metabolism.: The aim of this study was to know which plant foods are triggers for migraine and the latency time for the onset of pain.

Hope as a behavior and cognitive process: A new clinical strategy about mental health's prevention.

Introduction: Given the aging population, it is necessary to develop strategies for the prevention and promotion of mental health in the elderly. Hope as the ability to trace and maintain paths can be used as a key construct for these strategies, promoting cognitive health if stimulated.

Objective: Evaluate the behavior and cognitive development of elderly people through hope training as a clinical strategy for health promotion.

Brazilian air traffic controllers exhibit excessive sleepiness.

Unlabelled: Excessive sleepiness (ES) is an increased tendency to initiate involuntary sleep for naps at inappropriate times.

Objective: The objective of this study was to assess ES in air traffic controllers (ATCo).

Methods: 45 flight protection professionals were evaluated, comprising 30 ATCo, subdivided into ATCo with ten or more years in the profession (ATCo≥10, n=15) and ATCo with less than ten years in the profession (ATCo<10, n=15) and 15 aeronautical information services operators (AIS), subdivided into AIS with ten years or more in the profession (AIS≥10, n=8) and AIS with less than ten years in the profession (AIS<10, n=7), who were included as the control group.

Air traffic control activity increases attention capacity in air traffic controllers.

Unlabelled: Air traffic controllers simultaneously develop complex and multiple tasks in the course of their activities. In this context, concern is raised over the high level of attention needed by these professionals which can ultimately be affected by stress and fatigue.

Objectives: The objective of this study was to assess attention level in air traffic controllers (ATCo).

Sleep-deprivation enhances in adult rats the antagonistic effects of pilocarpine on cortical spreading depression: a dose-response study.

Conditions that facilitate epilepsy, such as sleep deprivation or the cholinergic muscarinic agonist pilocarpine (PILO), have been experimentally studied, as they are relevant for brain excitability control and could help in understanding the development of epilepsy in humans. In this work, following to 72h deprivation (D) of sleep by the water tank technique, adult Wistar rats were anesthetized with a 1g/kg urethane+40mg/kg chloralose mixture and cortical spreading depression (CSD) was recorded for a 1-2h period in the parietal surface. CSD propagation velocity was calculated based on the time spent for a CSD-wave to pass the interelectrode distance.

Malnutrition and REM-sleep deprivation modulate in rats the impairment of spreading depression by a single sub-convulsing dose of pilocarpine.

This study aimed to investigate the effect of a single injection of pilocarpine upon the phenomenon of cortical spreading depression (SD), in adult rats submitted to early malnutrition and/or to REM-sleep deprivation for 72h prior to the SD-recordings. The SD was recorded continuously for 3-4h in 13 well-nourished (W) and 15 early-malnourished (M) adult rats. One to two hours after the beginning of the recording session, a sub-convulsing intraperitoneal (i.
