Linking environmental factors with reflex action mortality predictors, physiological stress, and post-release movement behaviour to evaluate the response of white sturgeon Acipenser transmontanus Richardson 1836 to catch-and-release angling

Stoddard, Steven J. Cooke, David A. Patterson, Scott G. Hinch, David W. Welch, Glenn T. CrossinAbstractWhite sturgeon are the largest freshwater fish in North America and are the focus of an intense catch-and-release (C&R) fishery; the effects are largely unknown. We assessed the effect of fight and handling time, water temperature, river discharge rate, and fish size on physiological and reflex impairment responses of wild white sturgeon to angling. Sixty of these fish were tagged with acoustic transmitters to assess survival and post-release behaviour. Survival was high (100%). Water temperature and discharge influenced post-capture blood physiology. Specifically, lactate, chloride, and cortisol concentrations were elevated in individuals fought longer, and captured at higher water temperatures and river discharge. Cortisol was affected by fish size, with lower concentrations found in larger individuals. Only lactate and chloride were positively related to reflex impairment scores. Post-release movements were correlated with physiological state, fight characteristics and the environment. Specifically, higher blood lactate and chloride and those with longer fight times moved shorter distances after release. Contrastingly, higher levels of circulating glucose and potassium, as w...

Millions of people with post-traumatic stress disorder (PTSD) — from veterans to rape survivors — have new hope because of a watershed study showing that the injection of an anesthetic to a bundle of nerves in the neck can relieve their symptoms in a clinically significant way. The treatment is known as the stellate ganglion block, or SGB. Used since 1925 for problems such as pain in the arm and shingles, it is safe and effective. In the newly released, eight-week, U.S. Army-funded clinical trial of 108 active-duty service members with PTSD, the nonprofit research institute RTI International found that patients...

Authors: Stefano GB, Esch T, Kream RM Abstract The relaxation response derives its health benefits by reestablishing "normal" equilibria between the sympathetic and parasympathetic branches of the autonomic nervous system. Recent work suggests that this behavioral training provides positive effects on mitochondrial bioenergetics, insulin secretion, and reductions in pro-inflammatory and stress-related pathways. We have previously contended, however, that correlative associations of relaxation training with positive changes in gene expression in selected biological systems are strongly suggestive of adapti...

ConclusionsThe atypical clinical presentation of some CGD patients can make genotype –phenotype correlation with DHR flow data challenging. Genetic testing, while useful for confirmation of diagnosis, can take several weeks, and in some patients does not provide a conclusive answer. However, NADPH-oxidase-specific protein flow assessment offers a rapid alternative to identificatio n of the underlying genetic defect in cellular subsets, and can be utilized as a reflex test to an abnormal DHR flow. Further, it can provide insight into correlation between oxidative burst relative to protein expression in granulocytes and monocytes.

Wallace HayesAbstractBIA 10–2474 (3-(1-(cyclohexyl(methyl)carbamoyl)-1H-imidazol-4-yl)pyridine 1-oxide) is a novel fatty acid amide hydrolase (FAAH) inhibitor developed by BIAL for the treatment of medical conditions which would benefit from enhanced levels of endogenous anandamide (AEA) such as pain disorders. During a Phase I clinical trial one subject died after receiving BIA 10–2474 and others displayed neurological signs....

AbstractThe innervation of the long head of the biceps tendon (LHBT) is not sufficiently documented. This is a drawback since pathologies of the LHBT are a major source of shoulder pain. Thus, the study aimed to characterize structurally and molecularly nervous elements of the LHBT. The proximal part of 11 LHBTs was harvested intraoperatively. There were 8 female and 3 male specimens. Age ranged from 66 to 86  years. For structural analyses, nervous elements were viewed in the transmission electron microscope. For molecular characterization, we used general neuronal markers including antibodies against neurofilament a...

ConclusionsThese results showed a cardiac parasympathetic dominance to the same extent, underpinned by a similar arterial baroreflex activation during WI and HDT as well as control SP. Future studies may address their association with cold or hyperoxia to assess their ability to replicate autonomic cardiovascular adaptations to microgravity, swimming or scuba diving.

Conclusions: DM suturing can reattach DM, especially in moderate to severe, recurrent DMD with fewer postoperative complications and thereby reduce the need for corneal transplantation.
