Vaccination is a desirable emerging strategy to combat poultry red mite (PRM), Dermanyssus gallinae. We performed trials, in laying hens in a commercial-style cage facility, to test the vaccine efficacy of a native preparation of soluble mite extract (SME) and of a recombinant antigen cocktail vaccine containing bacterially-expressed versions of the immunogenic SME proteins Deg-SRP-1, Deg-VIT-1 and Deg-PUF-1. Hens (n=384 per group) were injected with either vaccine or adjuvant only (control group) at 12 and 17 weeks of age and then challenged with PRM 10days later...

Eccentric exercise has been shown to exert beneficial effects in both lipid profile and insulin sensitivity. Antioxidant supplementation during chronic exercise is controversial as it may prevent the physiological training-induced adaptations. The aim of this study was to investigate: 1) the minimum duration of the eccentric exercise training required before changes on metabolic parameters are observed and 2) whether antioxidant supplementation during training would interfere with these adaptations. Sixteen young healthy men were randomized into the Vit group (1 g of vitamin C and 400 IU vitamin E daily) and the placebo (PL) group...

BACKGROUND AND OBJECTIVE: Hyperhomocysteinemia is a well-known risk factor for cardiovascular disease. Although metformin therapy can increase homocysteine (Hcy) levels, it frequently is used as an oral medicine in women with polycystic ovary syndrome (PCOS), who might be at risk of catching diabetes mellitus. The aim of this study was to investigate the effect of metformin on the levels of serum Hcy, vitamin B12 (vit B12), and folic acid in patients with PCOS. MATERIALS AND METHODS: An interventional study was designed with 18 patients with PCOS at the Fatemehzahra infertility Hospital in Babol, Iran...

BACKGROUND: The pivotal role of vitamin D (vit D) in skeletal health is well known. Neonatal vit D storage at birth is dependent on maternal levels, and newborns receive 50-70% of their mother's 25-hydroxyvitamin D [25(OH)D]. Deficiency of vit D can lead to prematurity bone disease, with an incidence of up to 55% in infants weighing < 1000 g. The aim of this study is to assess the effectiveness of monitored supplementation of vit D in a population of preterm infants. METHODS/DESIGN: Preterm infants born at 24-32 weeks of gestation will be recruited within the first 7 days of life...

Neurological dysfunction as a result of neuroinflammation has been reported in sepsis and cause high mortality. High levels of cytokines stimulate the formation of neurotoxic metabolites by kynurenine (KYN) pathway. Vitamin B6 (vit B6) has anti-inflammatory and antioxidant properties and also acts as a cofactor for enzymes of the KYN pathway. Thus, by using a relevant animal model of polymicrobial sepsis, we studied the effect of vit B6 on the KYN pathway, acute neurochemical and neuroinflammatory parameters, and cognitive dysfunction in rats...

BACKGROUND: Hypertension is one of the primary modifiable risk factors for cardiovascular disease. Adequate vitamin D (vit D) levels have been shown to reduce vascular smooth muscle contraction and to increase arterial compliance, which may be beneficial in hypertension. Further, coenzyme Q10 (COQ10) through its action to lower oxidative stress has been reported to have beneficial effects on hypertension and heart failure. This study examined the possible cardiac and renal protective effects of vit D and COQ10 both separately and in combination with an angiotensin II receptor blocker, valsartan (vals) in l-NAME hypertensive rats...

Endoscopic optical imaging methods for the detection of mucosal lesions in the ENT area have been developed for better and earlier detection of these changes. They can be divided into horizontal methods group - showing the surface of the mucous membrane (autofluorescence, photodynamic diagnosis, Narrow Band Imaging, magnifying and contact endoscopy) and vertical methods group - visualizing different layers of the mucosa (optical coherence tomography and confocal endomicroscopy). Some of them are routinely used in practice, others are used in experimental mode and their introduction into practice may be a matter of the near future...

PURPOSE OF REVIEW: Metabolic syndrome (MetS) is associated with increased risk of obesity, type 2 diabetes mellitus and cardiovascular diseases. MetS prevalence has been associated with diet inadequacy. Conversely, the cumulative incidence of MetS has been inversely associated with a Mediterranean-style diet that includes many different health-beneficial nutrients. Adherence to a Mediterranean-style diet could reduce or at least stabilize metabolic risk factors. RECENT FINDINGS: Low serum level of fat-soluble micronutrients, such as carotenoids, vitamin (vit) A, D and E, has been linked to MetS...

A 3-year-old male presented with a large retroperitoneal mass and multiple metastases. Biopsy results suggested alveolar rhabdomyosarcoma bearing a methylated O6-methylguanine-DNA methyltransferase (MGMT) gene promoter. Serum microRNA-206 levels were elevated and remained high after three cycles of vincristine, dactinomycin, and cyclophosphamide (VAC). Replacement of vincristine, irinotecan, and temozolomide (VIT) for VAC induced a marked tumor reduction and normalization of the miR-206 levels. The patient completed 14 cycles of VIT with local radiotherapy and has been in remission for 31 months...

AIMS: Stem cells exposed to pathological levels of reactive oxygen species (ROS) at wound site fail to regenerate tissue. Molecular mechanism underlying differential levels of ROS-mediated regulation of stem cells remains elusive. This study elucidates mechanistic role of catalase at 10µM H<sub>2</sub>O<sub>2</sub>-induced proliferation of mouse bone marrow stromal (BMSC) and hematopoietic (HSPC) stem/progenitor cells. RESULTS: BMSCs and HSPCs depicted an increased growth rate and colony formation, in presence of 10µM but not 100µM concentration of H<sub>2</sub>O<sub>2</sub>, an effect that was perturbed by Vit...
