Obesity and Obstructive sleep Apnea (OSA) seems to bi-directional; obesity itself increases the risk of OSA, but on the other hand, OSA may also predispose the individuals to weight gain, both obesity and OSA share a common immune-metabolic link state which have a synergistic effect on the
BACKGROUND
Up to 84% of prematurely born infants suffer hypoxic, anoxic, and ischemic insults. Those infants with subsequent behavioral, motor or cognitive dysfunction represent 8-11% of all live births. Yet, no interventions employed during pregnancy attenuate risk of morbidity in those at-risk
OBJECTIVE
To observe the effects of different concentrations of arsenic trioxide (As(2)O(3)) on apoptosis and proliferation of human lung cancer cell line A549 in vitro under hypoxia and normoxia.
METHODS
A549 cells were treated with 0, 1, 2, 4 micromol/L As2O3 for 12, 24 and 48 h under hypoxia (5%
Despite intensive treatment, the outcome of high-risk neuroblastoma patients is poor with acquired multidrug resistance as an important cause. Previously, our group has shown that arsenic trioxide (As(2)O(3)) kills multidrug-resistant neuroblastoma cells in vitro and in vivo at clinically tolerable
The polyunsaturated fatty acids (PUFAs) of the omega 3 series are known to modulate adrenergic functions in ventricular myocytes. This study evaluated the influence of hypoxia duration and PUFA composition on the ability of cultured rat cardiomyocytes in producing alpha- and beta-adrenergic
With the exception of melanoma and non-Hodgkin's lymphoma, the incidence of cancer has peaked in the last several years, but rates and mortality are still high. Moreover, despite 50 years of intensive cancer research increasingly focused on genetic causes, no single unifying cause for cancer has
In gray matter (GM), anoxia induces prominent extracellular ionic changes that are important in understanding the pathophysiology of this insult. White matter (WM) is also injured by anoxia but the accompanying changes in extracellular ions have not been studied. To provide such information, the
The rapid changes in brain extracellular ion concentrations that occur with anoxia are important in understanding the pathophysiology of anoxic-ischemic brain injury. While previous studies have focused on the ionic changes that occur in gray matter areas of the brain, white matter (WM) is also
This study aimed to investigate the effects of hypoxia on Cu-induced antioxidant defense, Cu transport, and mitophagy in the liver of the large yellow croaker. Fish were exposed to hypoxia (3.0 mg L-1), Cu (120 μg L-1), and hypoxia (3.0 mg L-1) plus Cu (120 μg
Abnormal placental vasculature is associated with preeclampsia. Preeclampsia is of two types, i.e., early- and late-onset preeclampsia (LOP), both having different etiologies. We have earlier demonstrated low levels of omega-3 fatty acids and vitamin E in women with preeclampsia. The current study
Vitamin B12 and omega-3 fatty acids are critical for normal brain development and function and their deficiencies during pregnancy could have adverse effects on cognitive performance in children. Our earlier studies indicate that both maternal vitamin B12 and omega-3 fatty acids influence brain
The aim of this study was to investigate whether the omega-3 fatty acids help to improve erectile function in an atherosclerosis-induced erectile dysfunction rat model. A total of 20 male Sprague-Dawley rats at age 8 weeks were divided into three groups: Control group (n = 6, untreated sham operated
Ba(0.9)Co(0.7)Fe(0.2)Nb(0.1)O(3-δ) outperforms as a cathode in solid-oxide fuel cells (SOFC), at temperatures as low as 700-750 °C. The microscopical reason for this performance was investigated by temperature-dependent neutron powder diffraction (NPD) experiments. In the temperature range of 25-800
Background: The modulation of arachidonic acid (AA) metabolism pathway is identified in metabolic alterations after hypoxia exposure, but its biological function is controversial. We aimed at integrating plasma metabolomic and transcriptomic approaches to systematically explore the roles of the AA
