Layered double hydroxides (LDHs) have been recognized as potent electrocatalysts for oxygen evolution reaction (OER), but are lacking in hydrogen evolution reaction (HER) activities due to the sluggish kinetics of water dissociation in alkaline medium. Herein, aiming to simultaneously bolster the HER and OER kinetics, a metal-organic framework (MOF) mediated topotactic transformation tactic is deployed to fabricate holey ternary CoFeNi LDHs on nickel foam, exposing polygonal mesopores with atomistic edge steps and lattice defects. The optimized catalyst requires only an external voltage of 1.49 V to afford the water splitting current density of 10 mA cm-2 apart from the superb electrolytic stability, far surpassing the benchmark Pt/C||RuO2 couple. More importantly, mechanistic investigations utilizing advanced spectroscopies in conjunction with density function theory (DFT) understandings unravel while the synergetic effect among under-coordinated metal centers lowers the energy barrier of water dissociation, Fe-doping enables further modulating the d-band density of states (DOS) of Co and Ni in favor of intermediates binding, thereby promoting the intrinsic HER activity. buy RMC-7977 Operando Raman studies reveal negligible structural change of the LDHs during the HER process, whereas for OER the active sites can quickly turn into oxyhydroxides in the presence of lattice defects and under-coordinated metal centers.The unparalleled theoretical specific energy of lithium-sulfur (Li-S) batteries has attracted considerable research interest from within the battery community. However, most of the long cycling results attained thus far relies on using a large amount of electrolyte in the cell, which adversely affects the specific energy of Li-S batteries. This shortcoming originates from the low solubility of polysulfides in the electrolyte. Here, 1,3-dimethyl-2-imidazolidinone (DMI) is reported as a new high donor electrolyte for Li-S batteries. The high solubility of polysulfides in DMI and its activation of a new reaction route, which engages the sulfur radical (S3•- ), enables the efficient utilization of sulfur as reflected in the specific capacity of 1595 mAh g-1 under lean electrolyte conditions of 5 μLelectrolyte mgsulfur-1 . Moreover, the addition of LiNO3 stabilizes the lithium metal interface, thereby elevating the cycling performance to one of the highest known for high donor electrolytes in Li-S cells. These engineered high donor electrolytes are expected to advance Li-S batteries to cover a wide range of practical applications, particularly by incorporating established strategies to realize the reversibility of lithium metal electrodes.Use of dipeptidyl peptidase-4 (DPP-4) inhibitors, on the basis of spontaneous adverse event reports, has recently been suspected of causing splanchnic vein thrombosis. Here, we report the results of a population-based new-user active comparator cohort study addressing this hypothesis, comparing DPP-4 inhibitor initiators (n = 75 042) with initiators of glucagon-like-peptide-1 receptor agonists (GLP-1RAs) or sodium-glucose co-transporter-2 (SGLT2) inhibitors (n = 38 718). We estimated the hazard ratio (HR) associating DPP-4 inhibitor use with risk of splanchnic vein thrombosis using Cox regression. In a crude analysis, the incidence rate of splanchnic vein thrombosis was 0.22/1000 person-years among DPP-4 inhibitor initiators, compared to 0.17 among GLP-1RA/SGLT2 inhibitor initiators, corresponding to an unadjusted absolute incidence rate difference of 0.05 (95% confidence interval [CI] -0.04 to 0.14) and an HR of 1.29 (95% CI 0.78 to 2.15). Adjusting for potential confounders using stabilized inverse probability of treatment weighing, we obtained an absolute incidence rate difference of 0.03/1000 person-years (95% CI -0.07 to 0.14) and an HR of 1.18 (95% CI 0.62 to 2.26). No evidence of increased risk of splanchnic vein thrombosis was found in supplementary analyses, including an absence of any dose-response patterns. As such, we found no association between DPP-4 inhibitor use and splanchnic vein thrombosis risk.
To examine the effects of oral health factors related to oral function and their combination on mortality in older people.

Recent studies have reported that oral factors, including oral function, are associated with mortality.

The participants were 4765 community-dwelling individuals aged 75 and 80years. The follow-up period for survival or death was 3.5years, and the date of death was defined based on data managed by the insurer. A Cox proportional hazard model was applied to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for mortality as dependent variables for oral health factors, including the number of teeth, swallowing disability, oral dryness and oral hygiene and the combinations of oral health factors as independent variables.

In univariate analyses, all four oral health factors were significantly associated with mortality. After adjusting for age, sex, smoking, body mass index and medical history, and analysing the oral health factors separately, swallowing difficulty had the highest HR for mortality (adjusted HR, 2.12; 95% CI, 1.35-3.33). In the analysis using combinations of oral health factors as the independent variable, the participants with swallowing disability, oral dryness and poor oral hygiene had the highest HR for mortality (adjusted HR, 8.35; 95% CI, 3.45-21.08).

Oral health factors related to oral function appear to be associated with mortality risk and an accumulation of oral health factors increases mortality risk among older people.

As the tissue swells, the hair constriction tightens and may result in tissue necrosis and osseous changes secondary to ischemic necrosis. The objectives of this retrospective case series were to describe the radiographic characteristics of persistent hair mat strangulation in dogs, to identify clinical features that would distinguish between dogs with soft tissue lesions only and dogs with osseous changes and to describe the clinical outcome in these dogs. All dogs with clinically identified strangulating hair matting had radiographically identified soft tissues defects and over half of the limbs evaluated had osseous lesions including focal periostitis, bone remodeling, bone atrophy, lysis of bone, and occasionally subluxation of joints. Chronically matted hair and strangulating hair mats in dogs are recognized by veterinarians as a medical finding in animal neglect.
