Laura G Leahy
As many patients turn to vitamins and supplements to enhance energy, relieve fatigue, or generally feel better, it is important to understand the connection between the B vitamins and psychiatric symptomatology. Vitamins B6, B8, and B12 have been shown not only to reduce psychiatric symptoms but also shorten the duration of illness. Vitamin B9, also known as folate or folic acid, has also been associated with psychiatric symptoms. However, when patients lack a specific genetic enzyme, which converts folate/folic acid to its most usable form, L-methylfolate, the neuroprotective and neuropsychiatric benefits are lost...

Miles Gandolfi, Bimbi S Fernando
Arteriovenous fistulas can lead to a number of different chronic complications. We describe a case where a patient developed a thrombosis within her brachiobasilic arteriovenous fistula, which was manually manipulated in order to restore fistula flow. This resulted in a pulseless electrical activity cardiac arrest within a few minutes. After ten minutes of chest compressions and intubation, there was return of spontaneous circulation. No epinephrine was given nor shocks administered. Patient was extubated within minutes and was alert, orientated and haemodynamically stable...

CONTEXT: Premenopausal women have blunted counter-regulatory hormone responses (CRR) to hypoglycemia compared to men. Postmenopausal women have CRR similar to men; the premenopausal pattern can be restored by estrogen. However, glucagon and pancreatic polypeptide (PP) responses remain lower in postmenopausal women than in men. Since hyperandrogenemia contributes to the metabolic phenotype of polycystic ovary syndrome (PCOS), we hypothesize that CRR to hypoglycemia especially of glucagon and PP is exaggerated in premenopausal women with PCOS compared to premenopausal control women...

BACKGROUND: Huntington Disease is autosomal, fatal and progressive neurodegenerative disorder for which clinically available drugs offer only symptomatic relief. Emerging strides have indicated that antidepressants improve motor performance, restore neurotransmitters level, ameliorates striatal atrophy, increases BDNF level and may enhance neurogenesis. Therefore, we investigated sertraline and venlafaxine, clinically available drugs for depression with numerous neuroprotective properties, for their beneficial effects, if any, in quinolinic acid induced Huntington's like symptoms in rats...

Intravenously injected lipopolysaccharides (LPS) rapidly induce pulmonary platelet accumulation (PPA) and anaphylaxis-like shock (ALS) in mice. Macrophages reportedly release catecholamines rapidly upon stimulation with LPS. Here, we examined the involvement of macrophage-derived catecholamines in LPS-induced PPA and ALS. A catecholamine or Klebsiella O3 (KO3) LPS was intravenously injected into mice, with 5-hydroxytryptamine in the lung being measured as a platelet marker. The tested catecholamines induced PPA, leading to shock...

In an effort to better understand the consequences of early weaning (EW) for replacement beef heifers, a two-phase experiment was conducted investigating the impact on metabolic function and documenting reproductive characteristics. In phase 1, Angus×Simmental heifers (n=35) were stratified by BW and sire, and randomly assigned to either a normal weaning (NW, n=18) or EW (n=17) treatment. EW heifers were weaned at 107±3 days of age and provided access to a concentrate-based ration ad libitum with limit-fed mixed grass hay...

Central sleep apnea (CSA) affects many patients, with heart failure and results in hypoxia and nor-epinephrine release and is associated with high morbidity and mortality. Recent trials in the treatment of CSA using positive airway pressure therapies have failed to demonstrate improvement in mortality and as a result, the compensatory nature of CSA has been questioned. The detrimental effects from CSA are clear. While there may be a short term compensatory effect, the long term effects cause chronic insult to the cardiovascular system indicating that CSA should be treated, but alternative treatment options need to be considered...

Jiao-Tai-Wan (JTW), has been usually used for insomnia in traditional Chinese medicine (TCM). The previous study shown that JTW was benefit for depression-like behavior, but the possible mechanism is not clear. This study is to determine whether JTW was benefit for the treatment of lipopolysaccharide (LPS)-induced depression-like behavior in mice and explore its possible mechanism. All drugs were intragastrically administered once daily for 7 consecutive days. On the 7th day, LPS was injected into mice 30 min after drug administration...

On-call work is becoming an increasingly common work pattern, yet the human impacts of this type of work are not well established. Given the likelihood of calls to occur outside regular work hours, it is important to consider the potential impact of working on-call on stress physiology and sleep. The aims of this review were to collate and evaluate evidence on the effects of working on-call from home on stress physiology and sleep. A systematic search of Ebsco Host, Embase, Web of Science, Scopus and ScienceDirect was conducted...

Désirée Larenas-Linnemann
Due to differences between allergen immunotherapy (AIT) trials in patient populations, trial design (including primary efficacy variables), the definition of a pollen season, data analysis, and comparisons between AIT products with existing data, is not possible nor valid. The efficacy of two grass pollen AIT tablets, Oralair(®) and Grazax(®)/Grastek(®), should not be compared by looking at the percentage of score improvement in their respective trials. However, the evidence available concerning the efficacy and safety in trials can be compared by paying close attention to the scientific quality of the trials, details in the administration schedules, and safety issues...

The scaffold protein alpha-syntrophin (SNTA) regulates lipolysis indicating a role in lipid homeostasis. Adipocytes are the main lipid storage cells in the body, and here, the function of SNTA has been analyzed in 3T3-L1 cells. SNTA is expressed in preadipocytes and is induced early during adipogenesis. Knock-down of SNTA in preadipocytes increases their proliferation. Proteins which are induced during adipogenesis like adiponectin and caveolin-1, and the inflammatory cytokine IL-6 are at normal levels in the mature cells differentiated from preadipocytes with low SNTA...

AIMS: Epinephrine is unique among biogenic catecholamines as a potent agonist of β2-adrenoceptors. The β2-adrenoceptor mediated effects during development might be linked to the increase of epinephrine synthesis. Our purpose was to characterize β-adrenoceptor-mediated relaxation in the aorta of newborn and young rabbits (3 to 4months old), and to relate those responses with the epinephrine content of the adrenal gland. MAIN METHODS: The epinephrine levels and the tyrosine hydroxylase activity were determined in adrenal glands of newborn and young rabbits...

The NR4A orphan nuclear receptors function as early response genes to numerous stimuli. Our laboratory has previously demonstrated that overexpression of NR4A3 (NOR-1, MINOR) in 3T3-L1 adipocytes enhances insulin-stimulated glucose uptake. To assess the in vivo effect of NR4A3 on adipocytes, we generated transgenic mice with NR4A3 overexpression driven by the adipocyte fatty acid-binding protein (AP2) promoter (AP2-NR4A3 mice). We hypothesized that AP2-NR4A3 mice would display enhanced glucose tolerance and insulin sensitivity...

Rodeos are public events at which stockpeople face tests of their ability to manage cattle and horses, some of which relate directly to rangeland cattle husbandry. One of these is calf roping, in which a calf released from a chute is pursued by a horse and rider, who lassoes, lifts and drops the calf to the ground and finally ties it around the legs. Measurements were made of behavior and stress responses of ten rodeo-naïve calves marshalled by a horse and rider, and ten rodeo-experienced calves that were roped...

Central sleep apnea is a devastating disease which occurs in approximately 40% of patients with heart failure as well as patients with a history of stroke, opioid use and neurological conditions. It is associated with increased morbidity and mortality in heart failure likely due to the recurrent episodes of hypoxia and nor-epinephrine release. There have historically been few therapeutic options; positive airway pressure therapies have been the most common treatment to date. However, the adoption of positive airway pressure therapies has been limited due to poor patient adherence and acceptance and recent evidence of increased cardiovascular mortality in low ejection fraction heart failure patients with CSA...
