“Giant negative thermal expansion (NTE), over alpha = -30 x 10(-6)

K-1 (alpha: coefficient of linear thermal expansion), at room temperature can be achieved in Mn3ZnN-based antiperovskite manganese nitrides by simultaneous substitution of C and B for N as well as Sn for Zn. The developed NTE nitrides show larger negative alpha, although the width of the operating-temperature window is comparable to that of Mn3CuN-based materials developed to date. Such a large, isotropic, and high-stiffness NTE material can compensate for the large positive

thermal expansion of, for example, even aluminum or plastic materials. (C) 2011 American Institute of Physics. [doi:10.1063/1.3540604]“
“Background: Obesity and osteoporosis have origins in childhood, and both are affected by dietary intake and physical activity. However, there is little information Wnt signaling on what constitutes a diet that simultaneously promotes low fat mass and high bone mass accrual early in life.

Objective: Our objective was to identify dietary patterns related to fat and bone mass in children during the age period of 3.8-7.8 y.

Design: A total of 325 children contributed data from 13 visits over 4 separate study years (age ranges: 3.8-4.8, >4.8-5.8, >5.8-6.8, and >6.8-7.8 y). We performed reduced-rank regression to identify dietary patterns related

to fat mass and bone mass measured by dual-energy X-ray absorptiometry for each study year. Covariables included race, sex, height, weight, energy intake, calcium intake, physical activity measured by accelerometry, and time spent viewing television and playing outdoors.

Results: A dietary pattern characterized by a high intake of dark-green and deep-yellow vegetables was related to low fat mass and high bone mass; high processed-meat intake was related to high bone mass; and high fried-food intake was related to high fat mass. Dietary pattern scores remained related to fat mass and bone mass after all covariables were controlled for (P < 0.001-0.03).

Conclusion: Beginning at preschool age, diets rich in dark-green and deep-yellow vegetables and low in fried foods may lead to healthy fat and bone mass accrual in young children. Am J Clin Nutr 2010; 92: 294-303.

“The experimental study on the laser ac

“The experimental study on the laser acoustic signal in salt water with different salinities using high power pulsed CO2 laser has been carried out. By using a hydrophone to receive the sound signal and further analyzing in time domain, the effects of the salinity and pulse energy on the characteristics of the sound signals were disclosed.

The results show that the salinity has significant effect on the characteristics of the laser acoustic signal. As the salinity increases, the amplitude of the sound signal decreases. The profile of the sound signal also changes with the salinity. As the salinity decreases, the changes in the signal waveform show the loss of its originally bimodal shape. This phenomenon is also found in the laser energy which decreases when the salinity is kept constant.”
“Purpose: find more A meta-analysis was conducted to obtain a ‘quantitative’ estimate of the extent of genetic damage in mammalian somatic cells exposed to non-ionizing radiation emitted from extremely low frequency electro-magnetic fields (ELF-EMF) and to compare with that in unexposed control cells. Methods: The methods used for the meta-analysis were recommended in several standard text books. Three specific variables related to ELF-EMF exposure

“Background. Nephropathy associated with contrast medium exposure is a well-known complication Pitavastatin cost of IVP. However, it is uncertain whether iso-osmolar non-iodinated contrast medium (iodixanol) is less nephrotoxic than low-osmolar contrast medium (iohexol). Materials and Methods. In this single-center, double-blind, prospective study, 50 patients undergoing IVP were randomized into two groups receiving different contrast medium: iodixanol and iohexol. Patients in high risk for contrast nephropathy were included, 28 with renal insufficiency and 19 with diabetes mellitus. We compared the nephrotoxic

effect (contrast nephropathy), HM781-36B complement and cytokines profile between the iodixanol and iohexol groups. The mean volume of contrast medium in each IVP procedure was 0.8 mL/kg. Results. The incidence of contrast nephropathy was 4 percent among all patients (one iodixanol and one iohexol). We found no significant differences in contrast nephropathy and allergic reactions between the two groups. There was no significant difference in cytokine profiles in both groups (p 0.05).The incidence of allergic reaction was 16 percent among all patients. Twelve percent (3/25) had late reaction after iohexol exposure compared to four percent (2/25) with iodixanol (p = 1.0). One patient had severe skin rash due to late adverse reaction after iodixanol. No mortality was found. Conclusions. New iodixanol and iohexol contrast medium for routine IVP examination are safe and have low nephrotoxicity profile, especially in elderly or high-risk patients. Iodixanol contrast medium has an increased risk to induce severe late adverse reaction compared to iohexol. Allergic reaction may be the main adverse effect after contrast medium infusion.

Microglial activation has a central

Microglial activation has a central selective HDAC inhibitors role in this process and triggers excitotoxic, inflammatory, and oxidative damage in the developing brain. Neuroinflammation can persist over a period of time and sensitize the brain to subinjurious insults in early and chronic phases but may offer relative tolerance in the intermediate period through activation of endogenous anti-inflammatory, protective, and repair mechanisms.

“There is a robust mechanistic basis for the role of oxidation

damage to DNA in the aetiology of various major diseases (cardiovascular, neurodegenerative, cancer). Robust, validated biomarkers are needed to measure oxidative damage in the context of molecular epidemiology, to clarify risks associated with oxidative stress, to improve our understanding of its role in health and disease and to test intervention strategies BEZ235 mouse to ameliorate it. Of the urinary biomarkers for DNA oxidation, 8-oxo-7,8-dihydro-2′-deoxyguanosine (8-oxodG) is the. most studied. However, there are a number of factors which hamper our complete understanding of what meausrement of this lesion in urine actually represents. DNA repair is thought to be a major contributor to urinary 8-oxodG levels, although the precise pathway(s) has not been proven, plus possible contribution from cell turnover and diet are possible confounders. Most recently,

evidence has arisen which suggests that nucleotide salvage of 8-oxodG and 8-oxoGua can contribute substantially to 8-oxoG levels in DNA and RNA, at least in rapidly dividing cells. This new observation may add an further confounder to the conclusion that 8-oxoGua or 8-oxodG and its nucleobase equivalent 8-oxoguanine, concentrations in urine are simply a consequence of DNA repair. Further studies are required to define the relative contributions of metabolism, disease and diet to oxidised nucleic acids and their metabolites in urine in order to develop urinalyis as a better tool for understanding

human disease.”
“Objective-To assess survival-to-discharge rates of mares and foals and postoperative complications and fertility in mares following cesarean section (C-section).

Design-Retrospective case series.

Animals-95 mares.

Procedures-Medical and breeding records of mares that underwent C-section were reviewed; signalment, surgical technique, complications, survival-to-discharge rate, and pregnancy and foaling rates were recorded and evaluated. Foaling rates in the 3 years after C-section were compared with the cumulative foaling rate before C-section.

Results-C-section was performed because of dystocia (n = 71) or concurrent maternal disease (20) or was elective (4). Overall survival-to-discharge rate was 84% (80/95) for mares and 35% (28/80) for foals. Six of 15 mares that had partial fetotomies prior to C-section did not survive.

“Background: In patients with anomalous left coronary artery from the pulmonary artery (ALCAPA) left ventricular (LV) dilatation and dysfunction evolves due to diminished myocardial perfusion caused by coronary steal phenomenon. Using late gadolinium enhanced cardiovascular magnetic

resonance (LGE-CMR) imaging, myocardial scarring has been shown in ALCAPA patients late after repair, however the incidence of scarring before surgery and its impact on postoperative course after surgical repair remained unknown.

Methods: 8 ALCAPA-patients (mean age 10.0 +/- 5.8 months) underwent CMR before and early after (mean 4.9 +/- 2.5 months) coronary reimplantation procedures. GSK1120212 concentration CMR included functional analysis and LGE for detection of myocardial scars.

Results: LV dilatation (mean LVEDVI 171 +/- 94 ml/m(2)) and dysfunction (mean LV-EF 22 +/- 10 %) was present in all patients and improved significantly after surgery (mean LVEDV 68 +/- 42 ml/m(2), p = 0.02; mean LV-EF 58 +/- 19 %, p < 0.001). Preoperative CMR revealed myocardial scarring in 2 of the 8 patients and did not predict postoperative course. At follow-up CMR, one LGE-positive patient showed delayed recovery of LV function while myocardial scarring was still present in both patients. In two patients new-onset transmural scarring was found, although functional recovery after operation was sufficient. One of them showed a stenosis of the left coronary artery and required resurgery.

Conclusions: Despite diminished myocardial perfusion and severely compromised LV function, myocardial scarring was preoperatively only infrequently present.

“A new procedure of determining the time resolved capacitance of a plasma actuator during FDA approved Drug Library supplier operation is introduced, representing a simple diagnostic tool that provides insight into the phenomenological behavior of plasma actuators. The procedure is demonstrated by presenting example correlations between consumed electrical energy, size of the plasma region, and the operating voltage. It is shown that the capacitance of a plasma actuator is considerably increased by the presence of the plasma; hence a system that has previously been impedance matched can be considerably de-tuned when varying the operating voltage of the actuator. Such information is fundamental for any attempts to increase the energy efficiency of plasma-actuator systems.

Among the 29 patients (15 men, 14 women; mean age 36.2 years old), renal involvement was initially learn more found in 22 patients (75.9%). They were divided into 2 groups according to the presence or absence of relapse. We compared clinical and histopathologic differences between 15 patients with relapse and 14 patients without relapse. By univariate analysis, older age at onset, persistent rash, abdominal pain, hematuria, and underlying disease at the onset of HSP are significantly related to relapse. Among the histopathological variables, severity of leukocytoclasis and absence of IgM deposit on the vessel walls are significantly associated to relapsing disease (P < 0.05). Our results are significant, because, they may help to understand the predictive factors related to relapses of HSP in adults.

“Primary cilia are hair-like organelles singly distributed along the apical

surface of proximal and distal nephron tubules as mechanosensors. learn more The goal of this study was to use electron microscopy to systemically evaluate cilia changes in acute tubular injury (ATI) from both transplant and native renal biopsies. Three groups of cases were included: control group 1-native biopsies without major changes in renal tubules; study group 2-native biopsies with prominent ATI; and study group 3-renal transplant biopsies with prominent ATI (delayed renal function group). Extensive search for ciliary structures along renal tubules was conducted in each case, focused on proximal tubular areas with injured (diminished) apical microvilli. Singly located cilia were found in 3/19 specimens in control group 1, 4/18 in group 2 (native Selisistat mouse ATI), and 6/24 in group 3 (transplant ATI). Importantly, there were clusters of cilia in proximal tubules with markedly diminished apical microvilli in 3/24 biopsies from 2 patients in group 3, but none

from groups 1 and 2. The clusters of cilia ranged from 6 to 15 individual cilia along the apical surface with diminished apical microvilli. Under high magnifications, the cilia demonstrated 9 pairs of peripheral microtubules without a central pair of microtubules, consistent with primary cilia (9+0) rather than motile cilia (9+2). In summary, the authors found clusters of cilia in proximal tubules with remarkable apical microvillar injury in 3 renal transplant biopsies with ATI, implying a reactive, or repairing, process following tubular injury, thus they name this finding “”cilia metaplasia”".”

CsA nephrotoxicity MLN4924 supplier was assessed in terms of increased S.Cr (from 0.52 +/- 0.16 to 1.29 +/- 0.20 mg/ml), blood urea (from 24.69 +/- 1.89 to 75.88 +/- 2.33 mg/ml) and serum K (from 3.43 +/- 0.18 to 5.23 +/- 0.43 meq/l). CsA also caused significant increase (p<0.01) in MDA (from 0.74 +/- 0.13 to 2.96 +/- 0.43 nmol/mg protein) and significant decrease (p<0.01) in GSH and catalase in renal tissue. Telmisartan failed to restore the altered renal functions. On the other hand, it causes a significant improvement in the histological changes including the tubulointerstitial fibrosis and arteriolopathy (p<0.01). It also caused significant reduction (p<0.01) in CsA-induced oxidative stress. These findings suggested that telmisartan has a promising renoprotective effect against chronic CsA induced nephrotoxicity.

“The uptake of anthropogenic CO2 by the oceans since the onset of the industrial

revolution is considered a serious challenge to marine ecosystems due to ensuing carbonate-chemistry changes (ocean acidification). Furthermore, the CO2 uptake is reducing the ocean’s capacity to absorb future CO2 emissions.
