Although many different dietary studies on the prevention of negative energy balance related diseases are often encountered, this is the first study investigating the effects of boron supplementation on peripartum dairy cows' health in the light of an omics approach. Twenty-eight healthy cows (1 control and 3 experimental groups) were enrolled from 2 months before predicted calving until 2 months after calving. Experimental groups were assigned to receive boron at increasing doses as an oral bolus. Production parameters, biochemical profile, Nuclear Magnetic Resonance based metabolomics profile, and mRNA abundance of gluconeogenic enzymes and lipid oxidation genes were determined...

Ideal orthopedic coatings should trigger good osteogenic response and limited inflammatory response. The cerium valence states in ceria are associated with their anti-oxidative activity and anti-inflammatory property. In the study, we prepared two kinds of plasma sprayed CeO2 coatings with different Ce(4+) concentrations to investigate the effects of Ce valence states on the response of bone mesenchymal stem cells (BMSCs) and macrophage RAW264.7. Both the coatings (CeO2-A and CeO2-B) were characterized via XRD, SEM, and X-ray photoelectron spectroscopy...

Copper (Cu) parenteral administration is used in a beef cow-calf operations to prevent or correct Cu deficiency in bovines. At present, Zinc (Zn) salts have been incorporated to complement Cu antioxidant effect. A risk of hepatotoxicity generated by overdose is a negative consequence of injectable Cu application. Cu-Zn EDTA appears as an alternative; however, data about its toxicity is unknown. The aim of this study was to assess toxicity risk of different doses of Cu-Zn EDTA in calves. Thirty two Aberdeen Angus calves of 162 (±20) kg BW were assigned to 4 groups (n = 8), homogeneous in weight, sex, and age...

Magnesium has been investigated as a biodegradable metallic material. Increased concentrations of Mg(2+) around magnesium implants due to biodegradation contribute to its satisfactory osteogenic capacity. However, the mechanisms underlying this process remain elusive. We propose that activation of the PI3K/Akt signalling pathway plays a role in the Mg(2+)-enhanced biological behaviours of osteoblasts. To test this hypothesis, 6, 10 and 18 mM Mg(2+) was used to evaluate the stimulatory effect of Mg(2+) on osteogenesis, which was assessed by evaluating cell adhesion, cell viability, ALP activity, extracellular matrix mineralisation and RT-PCR...

The aim of the present study was to examine the effect of selenium (Se) deficiency on the expression of selenoproteins in chicken muscular stomach and to detect the correlation of selenoproteins with muscular stomach injuries. One-day-old broiler chickens were maintained for 55 days on a normal diet (0.2 mg/kg) or a Se-deficient diet (0.033 mg Se/kg). The expression levels of 25 selenoproteins, heat shock proteins (HSPs), and inflammatory factors were then examined by real-time PCR. Following this, the correlation between selenoproteins, HSPs, and inflammatory factors was analyzed by principal component analysis (PCA)...

Iodine is a key ingredient in the synthesis of thyroid hormones and also a major factor in the regulation of thyroid function. A local reduction of iodine content in follicular lumen leads to overexpression of local thyroid-stimulating hormone receptor (TSHr), which in turn excessively stimulates the regional thyroid tissue, and result in the formation of nodular goiter. In this study, we investigated the relationship between iodine content and sodium iodide symporter (NIS) expression by using the clinical specimens from patients with nodular goiter and explored the pathogenesis triggered by iodine deficiency in nodular goiter...

Selenium (Se) deficiency induces testicular functional disturbances, but the molecular mechanism remains unclear. In the present study, 1-day-old broiler chickens were maintained for 55 days with a normal diet (0.2 mg/kg) and a Se-deficient diet (0.033 mg Se/kg). Then, the messenger RNA (mRNA) levels of selenoproteins, heat shock proteins (HSPs), and inflammatory factors were examined. Se deficiency led to decreased selenoproteins (Gpx1, Selk, and Selh) and HSPs (HSP40, HSP60, and HSP90) (P < 0.05)...

Cardiovascular disease and diabetes mellitus are prominent features of glucose and lipid metabolism disorders. Adiponectin is a key adipokine that is largely involved in glucose and lipid metabolism processes. A growing body of evidence suggests that chronic exposure to inorganic arsenic is associated with cardiovascular disease and diabetes mellitus. We hypothesized that arsenic exposure may increase the risk of cardiovascular disease and diabetes mellitus by affecting the level of adiponectin. In this study, we examined serum adiponectin levels, as well as serum levels of metabolic measures (including fasting blood glucose, insulin, total cholesterol, triglyceride, and high-density lipoprotein (HDL)-cholesterol) in C57BL/6 mice exposed to inorganic arsenic in drinking water (5 and 50 ppm NaAsO2) for 18 weeks...

The aim of the present study is to evaluate the radioprotective effect of low-dose selenium supplementation (multiple administrations) on radiation toxicities and mortality induced by lethal dose of whole-body irradiation (WBI). For this, BALB/c mice received sodium selenite (4 μg/kg body wt) intraperitoneally for five consecutive days and subjected to WBI at an absorbed dose of 8 Gy ((60)Co, 1 Gy/min). Administration of sodium selenite was continued even during the post irradiation days three times a week till the end of the experiment...

Zinc dyshomeostasis may play a role in the pathogenesis of myocardial ischemia/reperfusion injury. The objective of this study was to investigate the expression profile of zinc regulated transporter like- and iron-regulated transporter-like proteins (ZIPs) and zinc transporter proteins (ZnTs) in cardiomyocytes and their modulation in response to hypoxia and reoxygenation. Adult rat ventricular myocytes (ARVMs) were subjected to 6 h of hypoxia, followed by 18 h of reoxygenation. Intracellular and extracellular zinc concentrations were determined using Fluozin-3 and Newport Green fluorescence, respectively...

The interaction between calcium and magnesium as a risk modifier for cardiovascular disease (CVD) has been largely overlooked in previous studies, for the strict regulatory system in blood has been thought to keep such homeostatic interactions under tight control. This study aimed to investigate the association between calcium-magnesium ratio in hair and subclinical coronary artery calcification. Using multiple linear regression analysis, we examined the associations between calcium-magnesium ratio in hair and the coronary calcium score (CCS) in 216 Koreans aged 40 years and above (122 men and 94 women)...

Recent studies have found that the serum zinc levels were associated with the risk of Parkinson's disease (PD), but the results were inconsistent. Thus, we conducted a meta-analysis to summarize the evidence from observational studies between them. Pertinent studies were identified by a search in PubMed, Embase, and Web of science up to July, 10, 2016. Standardized mean difference (SMD) and 95% confidence intervals (CI) with random-effect model was used to combine the results. Subgroup analysis and meta-regression were also conducted...

Iodine and iron are essential elements for healthy thyroid function. However, little is known about the association of iron and iodine with thyroid function in the general US population. We investigated iron and iodine status in relation to concentrations of thyroid hormones. We included 7672 participants aged 20 and older from three surveys (2007-2008, 2009-2010, and 2011-2012) of the National Health and Nutrition Examination Survey. Serum thyroid measures (including free and total T3 and T4, and TSH), serum iron concentration, and urinary iodine concentrations were measured...

Previous studies have shown that serum zinc and adiponectin levels are associated with insulin resistance in the polycystic ovary syndrome (PCOS) patients. But there is no study to evaluate serum zinc and adiponectin levels as predictor markers of PCOS, adjusted for anthropometric, biochemical, dietary intake, and physical activity measures. Ninety-one new PCOS cases (based on the Rotterdam criteria) and 85 healthy control women participated and individually matched based on age. Food intake of all participants obtained by the food frequency and physical activity level was assessed by the International Physical Activity Questionnaires...
