We utilize thioether and thiol groups for functionalizing metal-organic fra.eworks to facilitate the uptake and inclusion of metal *** example is TMBD,a terephthalic acid analog with four meS-substituents. In one case,TMBD and Pb ions form a robust channel structure equipped with free-standing thioether groups to provide for a pioneering MOF system capable of reversible metal uptake(e.g.,HgCl).

Introduction: This study aimed to assess the prevalence of Intra-dialytic hypotension (IDH) according to the european Best Practice Guidelines (eBPG) definition in relation to the number of haemodialysis sessions and the number of chronic haemodialysis patients and to identify its associated factors. Patients and methods: We conducted an observational, multicentre and looking-forward study of descriptive and analytical purposes over a 4-week period. The study included all patients with regular chronic haemodialysis with at least two sessions per week and a duration of 180 minutes, who consented to participate in the study and were over 15 years of age. Data collection was done with pre-established forms. The following data were collected: blood pressure before each session, at 30, 60, 120, 180 and 240 minutes of each session;socio-demographic data;dialysis data;clinical, paraclinical, therapeutic data and nursing interventions. Results: The mean age of the patients was 43.84 ± 12.10 years. Among 568 haemodialysis sessions recorded in 50 patients, IDH was noted in 12 haemodialysis sessions, representing a prevalence of 2.11%. Fatigue was found in 5 sessions with IDH episodes (41.66%) followed by yawning (25%), nausea ± vomiting (16.66%) and cramps (16.66%). As nursing interventions, Trendelenburg position and normal saline administration were performed in all IDH episodes. High blood pressure, inter-dialytic weight gain greater than 3 kg, Uf/H > 10 ml/kg/H, anaemia and hypoalbuminaemia were associated with the occurrence of IDH. Conclusion: The prevalence of IDH according to the eBPG definition is low. However, it is an important cause of morbidity and mortality, especially cardiovascular involvement, and the factors associated with its presence have been clearly identified.

The parental material of soils in the Qilian Mountains of northwest China is mainly aeolian loess containing CaCO3 which may remain in soils under the semiarid-arid climate. To disclose the CaCO3 characteristics change with the altitude and the terrain attributes, we surveyed 18 soil profiles in an altitude sequence from 3076 m to 4510 m in the Hulugou Watershed in the Qilian Mountains, measured CaCO3 contents of all genetic horizon samples, analyzed the densities, illuviation modes and depths of CaCO3 in the profiles, extracted values of the terrain attributes of the profiles including altitude slope, aspect, plane curvature, profile curvature and terrain wetness index (TWI) from the 90 m resolution SRTM3 DeM data on ArcGIS 9.3 platform. We found that CaCO3 weighted content of the profiles ranged from 1.30 g·kg-1 to 93.09 g·kg-1, CaCO3 density from 0.05 kg/m2 to 75.69 kg/m2, CaCO3 illuviation depth from 12 cm to 54 cm. CaCO3 illuviation modes could be divided into three types, i.e., no illuviation mode in which the profile has only A horizon or CaCO3 content -1, middle illuviation mode in which CaCO3 accumulated in a middle horizon, and down illuviation mode in which CaCO3 content increases with the depth. CaCO3 weighted content, density and illuviation depth had significant correlation with certain terrain attributes. In general, the altitude sequence is an effective way to study CaCO3 characteristics in the alpine region, and the data of terrain attributes which can influence the precipitation and its redistribution in soil are potential in predicting soil CaCO3 characteristics in the alpine region.

The kinetics of carbothermic reduction of manganese ore from ka’oje deposit has been established. X-Ray diffra.tion analysis of the as-mined ore samples affirmed the presence of pyrolusite as the major manganese mineral in the ore, existing alongside with iron mineral present as hematite optically identified by transmitted infra.ed light microscopy. Samples with particles size ranges—106 μm were isothermally treated using charcoal of 52.17% carbon content as the reductant. The treatment was carried out at 550°C, 600°C, 650°C and 750°C with varied roasting retention time. Ore-mineral reduction kinetic model equations were developed using the generated thermal data. Results showed that the apparent activation energy (ea) of the chemical reaction controlled reduction was 19.99 kJ/mole using the diminishing area rate equation. Obtained ea values for diffusion controlled reduction of the ore-minerals were 36.28 kj/mole and 29.56 kJ/mole using Jander and Ginsthing-Brounshtein equations respectively. These hereby established reduction susceptibility of the manganese oxide mineral from higher oxide to lower oxides meant for further hydrometallurgical treatments.

Background The chronic pathological changes in vascular walls of hypertension may exert destructive effects on multiple organ systems. Accumulating evidence indicates that inflammatory reactions are involved in the pathological changes of hypertension. Three peroxisome proliferator-activated receptors （PPARs） have been identified： PPARa, PPARβ/δ, and PPARγ, all of which have multiple biological effects, especially the inhibition of inflammation. The aim of this study was to evaluate PPAR isoforms expression profile in important organs of spontaneously hypertensive rats （SHR） and to understand the modulation of endogenous PPAR isoforms under inflammatory condition. methods l]ssues （kidney, liver, heart, and brain） were dissected from SHR and age-matched control Wistar-kyoto rats （WkY） to investigate the abundance of PPAR isoforms and PPAR-responsive genes （acyI-CoA oxidase and CD36）. The expression of CCAAT/enhancer-binding protein 6 （C/eBP6）, which can trans-activate PPARγ expression, was also observed. The inflammatory response was analyzed by the expression of inflammatory mediators inducible nitric oxide synthase （iNOS）, intercellular adhesion molecule-1 （ICAM-1）, vascular cell adhesion molecule-1 （VCAM-1）, e-selectin, interleukin-1 beta （IL-1β）, and tumor necrosis factor alpha （TNFα）, and formation of carbonyl and nitrated proteins. Results The expressions of 3 PPAR isoforms and PPAR-responsive genes were markedly upregulated in SHR compared with those of WkY. Specifically, the expression of PPARa protein in the kidney, liver, heart and brain increased by 130.76 %, 91.48%, 306.24%, and 90.70%; PPARβ/δ upregulated by 109.34%, 161.98%, 137.04%, and 131.66%; PPARγ increased by 393.76%, 193.17%, 559.29%, and 591.18%. In consistent with the changes in PPARy, the expression of C/eBPδ was also dramatically elevated in SHR. Inflammatory mediators expressions were significantly increased in the most organs of SHR than WkY. As a consequence, increased formation of carbony

Non-stoiehiometry effect on the extreme magnetoresistanee is systematically investigated for the Weyl semimetal WTe2. Magnetoresistance and Hall resistivity are measured for the as-grown samples with a slight difference in Te vacancies and the annealed samples with increased Te vacancies. The fits to a two-band model show that the magnetoresistanee is strongly dependent on the residual resistivity ratio （i.e., the degree of non-stoichiometry）, which is eventually understood in terms of electron doping that not only breaks the balance between electron-type and hole-type carrier densities, but also reduces the average carrier mobility. Thus the compensation effect and ultrahigh mobility are probably the main driving force of the extreme magnetoresistance in WTe2.
