Endothelial glycocalyx injury is involved in heatstroke-associated coagulopathy and protected by N-acetylcysteine
DiscussionOur results indicate that the poor prognosis of HS patients correlates with severe coagulation disorders, coagulation abnormalities in HS rats are associated with the damage of EGCX, and NAC improves HS-induced coagulopathy, probably through its protection against EGCX injury by preventing ROS generation.

Mitochondrial medicine therapies: rationale, evidence, and dosing guidelines
Purpose of review Primary mitochondrial disease is a highly heterogeneous but collectively common inherited metabolic disorder, affecting at least one in 4300 individuals. Therapeutic management of mitochondrial disease typically involves empiric prescription of enzymatic cofactors, antioxidants, and amino acid and other nutrient supplements, based on biochemical reasoning, historical experience, and consensus expert opinion. As the field continues to rapidly advance, we review here the preclinical and clinical evidence, and specific dosing guidelines, for common mitochondrial medicine therapies to guide practitioners ...

Is Aberrant Reno-Renal Reflex Control of Blood Pressure a Contributor to Chronic Intermittent Hypoxia-Induced Hypertension?
This study demonstrated unaltered vascular conductance in response to lumbar sympathetic stimulation in CIH-exposed rats. Aortic compliance was increased and estimated blood volume was unchanged in CIH-exposed rats. Increased blood pressure was related to an increase in cardiac output, which was confirmed by echocardiography (Lucking et al., 2014). It is suggested therefore that hypertension in the CIH model can be evoked by over-excitation of the cardiac arm of sympathetic nervous system (SNS), even before mechanisms of enhanced peripheral vasoconstriction and endothelial dysfunction are initiated (Naghshin et al., 2009)....

Oral Cannabidiol Prevents Allodynia and Neurological Dysfunctions in a Mouse Model of Mild Traumatic Brain Injury
Conclusion In conclusion, our data demonstrate that mTBI causes late sensorial affective/cognitive deficiencies linked to altered neurotransmitter release at cortical level. Moreover, we showed that chronic CBD treatment reduces behavioral dysfunctions by restoring at least in part cortical biochemical processes. Taken together, our results suggest that CBD could represent a novel approach for the management of neuropsychiatric disorders associated with TBI. Author Contributions CB, LL, and RR conceived and designed the experiments. CB, MI, SB, FR, RI, and RM performed the experiments. GP, LS, SP, RR, LL, and IM analyze...

Apelin-13 Suppresses Neuroinflammation Against Cognitive Deficit in a Streptozotocin-Induced Rat Model of Alzheimer ’s Disease Through Activation of BDNF-TrkB Signaling Pathway
Conclusion The data in this manuscript demonstrates that apelin-13 upregulates BDNF against STZ-induced congnitive impairment by suppressing glial cell activity and inflammatory factors release. This suggests apelin signaling may be a new target in the treatment of AD. Ethics Statement All experimental protocols were carried out according to the National Institutes of Health Guide for the Care and Use of Laboratory Animals approved by the Central South University at XiangYa Animal Care and Use Committee. Author Contributions XqQ and LH conceived the study and contributed to its experimental design. HqL carried out the...

Molecules, Vol. 23, Pages 3305: Overview on the Effects of N-Acetylcysteine in Neurodegenerative Diseases
azzon N-acetylcysteine (NAC), which is an acetylated cysteine compound, has aroused scientific interest for decades due to its important medical applications. It also represents a nutritional supplement in the human diet. NAC is a glutathione precursor and shows antioxidant and anti-inflammatory activities. In addition to the uses quoted in the literature, NAC may be considered helpful in therapies to counteract neurodegenerative and mental health diseases. Furthermore, this compound has been evaluated for its neuroprotective potential in the prevention of cognitive aging dementia. NAC is inexpensive, commercially avai...
