Research progress on measurement methods and evaluation of the hemodialysis adequacy index Kt/V.

The most common form of replacement therapy for end-stage renal disease (ESRD) is hemodialysis, and the adequacy of hemodialysis is strongly associated with the quality of life and long-term survival of patients. Kt/V is currently one of the most important indicators for evaluating the adequacy of hemodialysis. There are many methods for measuring Kt/V, such as blood collection and measurement, dialysate measurement, bioresistive resistance, WinNonlin software analysis, and artificial intelligence.

Multi-Ce-Inserted Phospho(III)tungstate Containing Three Building Units with Prominent Peroxidase-Mimicking Activity for Detecting l-Cysteine.

An attractive isonicotinic acid-ornamented octa-Ce-inserted phospho(III)tungstate [HN(CH)]Na[Ce(HO)WNaO(INA)][HPWO][HPWO]·30HO () (HINA = isonicotinic acid) has been isolated through the deliberately designed one-step assembly strategy, in which the HPO heteroanion template was introduced into the Ce/WO system in the presence of HINA. The polyoxoanion of consists of two identical [Ce(HO)WNaO(INA)][HPWO][HPWO]} subunits linked by Ce-O-W bonds. The polyoxoanion exhibits three kinds of polyoxotungstate building blocks [WNaO(INA)], [HPWO], and [HPWO], in which [WNaO(INA)] and [HPWO] building units can be considered as seeds driven by the coordination of additional Ce ions to induce aggregation of [HPWO] fragments.

Objective: This study aims to compare the effect of pure aerobic exercise and combined aerobic resistance exercise on dialysis adequacy and quality of life in patients on maintenance hemodialysis.

Materials And Methods: A total of 45 patients on maintenance hemodialysis were divided into three groups: pure aerobic exercise group, combined aerobic resistance exercise group, and control group. Patients in the control group were only given the usual treatment, which included dietary guidance, drug therapy, and hemodialysis.

Dual-Functionalized Mixed Keggin- and Lindqvist-Type Cu-Based POM@MOF for Visible-Light-Driven H and O Evolution.

The development of logical visible-light-driven heterogeneous photosystems for water splitting is a subject of new research. As the first example of a noble-metal-free photocatalyst for both H and O production, a high-nuclear {Cu(μ-Cl)(μ-Cl)}-based polyoxometalate (POM)@metal-organic framework (MOF) (ZZULI-1) is rationally designed to serve as a robust dual-functionalized photocatalyst. ZZULI-1 exhibits highly efficient photocatalytic H evolution (6614 μmol g h) and O evolution (1032 μmol g calculated for the first 6 min).

Preventative effects of metformin on glucocorticoid-induced osteoporosis in rats.

This study evaluated the preventative effects of metformin (Met) on glucocorticoid (GC)-induced osteoporosis in a rat model, compared with alendronate (Aln). Twenty-eight 3-month-old female Sprague-Dawley rats were randomly assigned into four groups: normal control (Ctr), methylprednisolone (MP, 13 mg/kg/day, sc, 5 days per week), MP plus Aln orally (1 mg/kg/day), and MP plus Met orally (200 mg/kg/day). After 9 weeks, serum bone metabolic biochemistry, bone densitometry and histomorphometry were performed.

Semiconductive Copper(I)-Organic Frameworks for Efficient Light-Driven Hydrogen Generation Without Additional Photosensitizers and Cocatalysts.

As the first example of a photocatalytic system for splitting water without additional cocatalysts and photosensitizers, the comparatively cost-effective Cu I -based MOF, Cu-I-bpy (bpy=4,4'-bipyridine) exhibited highly efficient photocatalytic hydrogen production (7.09 mmol g  h ). Density functional theory (DFT) calculations established the electronic structures of Cu-I-bpy with a narrow band gap of 2.

Organized Aggregation Makes Insoluble Perylene Diimide Efficient for the Reduction of Aryl Halides via Consecutive Visible Light-Induced Electron-Transfer Processes.

The consecutive photo-induced electron-transfer (conPET) process found with perylene diimide (PDI) overcomes the limitation of visible-light photocatalysis and sheds light on effective solar energy conversion. By the incorporation of PDI into a metal-organic polymer Zn-PDI, a heterogeneous approach was achieved to tackle the poor solubility and strong tendency to aggregate of PDIs that restricted the exploitation of this outstanding homogeneous process. The interplay between metal-PDI coordination and π···π stacking of the organized PDI arrays in Zn-PDI facilitates the conPET process for the visible light-driven reduction of aryl halides by stabilizing the radical-anion intermediate and catalyst-substrate interacted moiety.

A photosensitizing decatungstate-based MOF as heterogeneous photocatalyst for the selective C-H alkylation of aliphatic nitriles.

The efficient photosensitizing of decatungstate-based MOF with 1D channels was achieved via in situ synthesis under solvothermal conditions for light driven acceleration of β- or γ-site C-H alkylation of aliphatic nitriles. The high catalytic efficiency, excellent size selectivity, high stability and good recyclability of the photocatalyst offer an environmentally-friendly route for widening the scope of accessible nitriles in both laboratory and industry.

Merging of the photocatalysis and copper catalysis in metal-organic frameworks for oxidative C-C bond formation.

The direct formation of new C-C bonds through photocatalytic oxidative coupling from low reactive sp C-H bonds using environmentally benign and cheap oxygen as oxidant is an important area in sustainable chemistry. By incorporating the photoredox catalyst [SiWORu(HO)] into the pores of Cu-based metal-organic frameworks, a new approach for merging Cu-catalysis/Ru-photocatalysis within one single MOF was achieved. The direct Cu-O-W(Ru) bridges made the two metal catalyses being synergetic, enabling the application on the catalysis of the oxidative coupling C-C bond formation from acetophenones and -phenyl-tetrahydroisoquinoline with excellent conversion and size-selectivity.
