    Notes: Objective Gestational diabetes is associated with increased risk of developing noninsulin-dependent diabetes (NIDDM) later in life. By the time that a diagnosis of NIDDM is established, functional disturbances in the vascular system may be observed. This study was planned to assess macro- and microvascular function in nonpregnant women without signs of diabetes two to four years after a pregnancy complicated with gestational diabetes.Design Cross-sectional study.Setting Vascular research laboratory in the obstetric unit of a university hospital.Participants Seventeen nonpregnant, healthy women with a history of gestational diabetes and 20 nonpregnant control women of similar age without previous diabetes.Methods For quantification of the mechanical properties in large arterial vessels the wall movements of the abdominal aorta and left common carotid artery were recorded with an ultrasonic tracking system. Microvascular perfusion in the skin of the hand and foot was recorded by a laser Doppler technique to assess the vasodilatory response induced by transcutaneous acetylcholine.Results Women in the gestational diabetes group showed evidence of increased wall stiffness in the common carotid artery and a lower maximum incremental velocity of the pulsatile vessel diameter change in both aorta and carotid artery compared with controls. Acetylcholine induced vasodilatation in both hand and foot was lower in women with previous gestational diabetes compared with controls.Conclusion Abnormal vascular function was found in asymptomatic women with a history of gestational diabetes. It is speculated that these abnormalities might be early evidence of vascular complications associated with subsequent NIDDM.

    Notes: The expressions of 78 protein kinases, 24 protein phosphatases and 31 phosphoproteins were investigated by Kinetworks™ analysis in brain and spinal cord tissue of transgenic mice over-expressing G93A mutant superoxide dismutase (mSOD), a murine model of amyotrophic lateral sclerosis (ALS). In the brains of affected mSOD mice, we observed increased expression of cAMP-dependent protein kinase (PKA, 111% increase compared with control), and protein phosphatase 2B Aα-catalytic subunit (calcineurin, 109% increase), and reductions in the levels of PAK3 (76% decrease) and protein phosphatase 2C Cβ-subunit (32% decrease). Increased Ser259 phosphorylation of Raf1 (126% increase) in mSOD mice correlated with higher expression of p73 Raf1 (147% increase). There was also increased p73 Raf1 (69% increase) and Ser259 phosphorylation (45% increase) in the spinal cords of mSOD mice. While adducin underwent enhanced phosphorylation (αS724, 90% increase; γS662, 290% increase) in mSOD brain, its phosphorylation was lower in the mSOD spinal cord (αS724, 53% decrease; γS662, 46% decrease). In spinal cords of affected mSOD mice, we also observed elevated expression of casein kinase 1δ (CK1δ, 157% increase), JAK2 (84% increase), PKA (183% increase), protein kinase C (PKC) δ (123% increase), p124 PKCµ (142% increase), and RhoA kinase (221% increase), and enhanced phosphorylation of extracellular regulated kinases 1 (ERK1, T202/Y204, 90% increase), and 2 (ERK2, T185/Y187, 73% increase), p38 MAP kinase (T180/Y182, 1570% increase), and PKBα (T308, 154% increase; S473, 61% increase). There was also reduced phosphorylation of RB (S780, 45% decrease; S807/S811, 65% decrease), Src (Y418, 63% decrease) and p40 SAPK/JNKβ (T183/Y185, 43% decrease). Variability in the expression of kinases, phosphatases and phosphorylation of their substrates was observed even in mutant animals having a similar phenotype. The expression and phosphorylation differences between mSOD and control mice were dissimilar to those between ALS patients and controls. This finding indicates that the activation of protein kinases and phosphoproteins is different with neuron loss in the mSOD mouse compared with that seen in patients with the sporadic form of ALS.

    Notes: The purpose of this research was to describe perceptions of infant health, caregiving at home, and help seeking by mothers of low birthweight (LBW) infants (n= 30) and mothers of normal birthweight infants (n= 30). In this descriptive study, data were analyzed through multiple regression, t tests, and content analysis of responses to researcher-constructed questionnaires. There were statistically significant relationships between: infant health and both confidence in caregiving (R2= 0.18, p 〈 0.001) and caregiver burden (R2= 0.29, p 〈 0.001); preparation for caregiving and confidence in caregiving (R2= 0.10, p 〈 0.05); and confidence in caregiving and caregiver burden (R2= 0.12, p 〈 0.01). Compared with mothers of normal birthweight infants, mothers of LBW infants perceived poorer infant health, t (58) =–2.02, p= 〈 0.05, and more caregiver burden, t (58) = 3.50, p= 〈 0.001. Mothers reported seeking help from a variety of resources, mostly nonprofessional for questions on infant care or nonserious infant health problems, and mostly physicians for questions on serious infant health problems. Nurses can use knowledge of mothers' perceptions of infant health, caregiving, and help seeking to facilitate mothers' management of caregiving and resource use.

    Notes: Abstract A new highly sensitive spectrophotometric method for determination traces of cadmium using Cd-(II)-KI-Crystal Violet system in the presence of Triton X-100-poly(vinyl) alcohol (PVA) mixture has been developed. The apparent molar absorptivity of the system is 1.77 × 105 1-mol−1 cm−1 and its Sandell's sensitivity is 6.35 × 10−4 μg·Cd·cm2−. Beer's law is obeyed up to 0.32 μg·Cd(II)·ml−1. The method has been applied to determine Cd(II) in waste water, rice and pork meat samples with satisfactory results.

    Variability of extreme precipitation over Yunnan Province, China 1960–2012 (2014)
    Wiley-Blackwell
    Details
    Publication Date: 2014-03-15
    Description: ABSTRACT This study investigated spatial and temporal variations of extreme precipitation over Yunnan Province during 1960–2012. On the basis of a dataset from 120 meteorological stations covering the region, ten precipitation indices derived from daily precipitation were computed and analysed. Our results indicate the precipitation indices showed spatially complex trends. Most precipitation indices present increasing trends in western Yunnan and decreasing trends in eastern Yunnan. The western, southern and central regions experienced an increase in consecutive dry days (CDDs) and decrease in consecutive wet days (CWDs). In addition, a widespread increase was also found in precipitation intensity over Yunnan. On a region-wide scale, a weak decrease was observed in total precipitation, accompanied by an increase in precipitation intensity. CDDs tended to be prolonged while the CWDs tended to be shortened. The days with precipitation amounts totaling more than 10 mm and maximum 5-day precipitation amount had decreasing but not significant trends. In contrast, insignificant increases were found for the maximum 1-day precipitation and annual total precipitation exceeding 95th and 99th percentiles. The contribution of extreme precipitation to total precipitation increased during 1960–2012. Overall, occurrences of extreme precipitation are more concentrated in time. The weakening of the Asian summer monsoon strength and local topography had contribution to the variations of extreme precipitation over Yunnan. However, the forcing mechanisms are very complicated and need to be studied in subsequent work.

    Feasibility study of using intravoxel incoherent motion mri to detect parotid gland abnormalities in early-stage Sjögren syndrome patients (2015)
    Wiley-Blackwell
    Details
    Publication Date: 2015-11-21
    Description: Purpose To determine whether intravoxel incoherent motion (IVIM) magnetic resonance imaging (MRI) could detect parotid gland abnormalities in Sjögren's syndrome (SS) patients who were not identified by conventional MRI. Materials and Methods Ten consecutive patients with clinically proven SS who were not identified by conventional MRI were assessed by IVIM MRI with a 3.0T MRI scanner. Quantitative parameters (tissue diffusivity, D; pseudodiffusion coefficient, D*; perfusion fraction, f) derived from IVIM MRI were compared between the SS group and healthy control group ( n  = 15). A receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of each significant parameter. Results Excellent inter- and intrareader agreements were obtained during the measurement of D, f, and D* values (interreader, 0.980, 0.942, and 0.883; intrareader, 0.991, 0.952, and 0.896, respectively). All three parameters of the SS group were significantly higher than those of the healthy group (D, 1.049 ± 0.056 × 10 −3 mm 2 /s vs. 0.976 ± 0.116 × 10 −3 mm 2 /s, P  = 0.012; D*, 20.410 ± 1.786 × 10 −3 mm 2 /s vs. 18.764 ± 2.433 × 10 −3 mm 2 /s, P  = 0.013; f, 0.207 ± 0.003 vs. 0.182 ± 0.002, P  = 0.004). ROC analysis showed that the f value had the best diagnostic performance (AUC, 0.712; Sensitivity, 0.80; Specificity, 0.57; Cutoff value, 0.185) in detecting the parotid gland abnormalities in early SS patients. Conclusion IVIM MRI detected parotid gland abnormalities in early-stage SS patients. J. Magn. Reson. Imaging 2015.
