Obstructive sleep apnea (OSA) has been strongly associated with several cardiovascular disorders during the past decade, and studies suggested that there might be a causal relationship. Recent studies have described several pathophysiologic mechanisms that are active in OSA and may participate in the development of cardiovascular disorders. Primarily, the repetitive respiratory events that occu...

Many shallow coastal systems experience diel fluctuations in dissolved oxygen (DO) and pH that can intensify throughout the summer season expose estuarine organisms to repeated episodes of hypoxia acidification. In temperate regions, larval release economically important blue crab Callinectes sapidus occurs summer, while earliest stage (zoea I) larvae are susceptible persistent low DO condition...

Objective(s): Impairment of nerve cells of brain induced by hypoxia results in energy-deprivation and dysfunction, which accompanies with neurons apoptosis. Improving function of nerve cells is important for treating cerebral anoxia. This study aimed to investigate the role of Quercetin (Quer) in hypoxia-induced injury of pheochromocytoma (PC-12) cells. Materials and Methods: PC-12 cells were c...

mouth breathing might not always result in hypoxia, but can contribute to it. the aim of the present study was to determine the effect of mouth breathing on hypoxia. based on a pilot study, 323 patients with mouth breathing were selected. assessment of mouth breathing was based on clinical examination and questionnaires filled out by patients and their companions. the patients were also examine...

Abstract Introduction Nocturnal hallucinations can be part of a wide array different disorders, like sleep disorders (e.g. narcolepsy), visual impairment Charles-Bonnet syndrome), neurodegenerative Lewy Body Dementia) and psychiatric schizophrenia). We explore the differential diagnosis, challenging diagnostic workup limited therapeutic options in this patient with complex nocturnal hallucinati...

background : foreign body aspiration is a common medical emergency among children that can lead to lethal complications especially in neglected or misdiagnosed cases. case report: this article is a report of a 15-month-old child who aspirated food materials and after chocking crisis, she presented with unspecific respiratory symptoms and treated for respiratory tract infections. after five days...

PURPOSE We verify the sodium fraction excretion rate (FE Na) and potassium fraction excretion (FE K) rates in monosymptomatic nocturnal enuresis. We also correlate FE Na and FE K to urinary osmolality, nocturnal polyuria and vasopressin in the same population. MATERIALS AND METHODS A total of 438 children 6 to 15 years old (mean age 9.7) presenting with monosymptomatic nocturnal enuresis were...

The relevance of studies related to the features respiratory disorders during sleep is undeniable due steady growth worldwide prevalence apnea syndrome, which leads a decrease in quality life, risk early cardiovascular diseases together with cerebrovascular, endocrine, and pulmonary disorders. aim this study was determine relationship between morning serum melatonin, blood oxygen saturation (Sр...

Abstract Introduction Obstructive sleep apnea syndrome (OSAS) is the most common disorder and it associated with arterial hypertension, heart failure, coronary artery disease as well atrial fibrillation. The underlying pathomechanisms for this association are only incompletely understood. In recent years long non-coding RNAs (lncRNA) have been shown to be involved in various cardiovascular path...
