Ac‐SDKP modulates apoptosis via HSP27 and the FAS/FASL and mitochondrial axes
Animal Models and Experimental Medicine, EarlyView.Schematic diagram of Ac‐SDKP regulating the FAS/FASL and mitochondrial apoptosis pathways via HSP27. Ac‐SDKP inhibits HSP27 expression, activates the FAS/FASL pathway and Caspase‐3 signaling, increases Caspase‐8 and Caspase‐3 expression, and induces cell apoptosis.

Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT In this study, saponification variables were optimized using a face‐centred central composite design‐response surface methodology. The variables included reaction temperature (50°C–120°C), reaction time (30–180 min), KOH concentration (0.5–3 M) and pyrogallol concentration (0–1% w/v).

Dynamic Characteristics of Suspended Load and Bed Load Transport in Meltwater Runoff of Qiyi Glacier
Shuitu Baochi Xuebao[Objective] The transportation of sediment via glacial meltwater can not only reflect the glacial erosion and landform evolution, but also is one of the important sediment sources for the downstream river.

Synthesis of a Novel Amine‐Based Curing Agent for Epoxy Resins Derived From Vanillin
Journal of Applied Polymer Science, EarlyView.The four‐step synthesis of a new bio‐based amine hardener is described starting from vanillin as a bio‐based compound. The hardener ADBA was utilized to cure DGEBA and the resulting Tg,tanδmax was determined via DMA. Compared to other bio‐based curing agents, our curing agent is obtainable in a high yield and leads to a superior Tg of 135°C.

Factors controlling the accelerated expansion of Imja Lake, Mount Everest region, Nepal
Annals of Glaciology, 2016 This study explores the link between area increase of Imja Tsho (Lake) and changes of Imja Glacier (area ~25km2) under the influence of climate change using multitemporal satellite imagery and local climate data. Between 1962 and 2013, Imja Lake expanded

The Anatomical Record, EarlyView.Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Glacierized headwater streams as aquifer recharge corridors, subarctic Alaska
Geophysical Research Letters, 2017 Arctic river discharge has increased in recent decades although sources and mechanisms remain debated. Abundant literature documents permafrost thaw and mountain glacier shrinkage over the past decades. Here we link glacier runoff to aquifer recharge via

The Anatomical Record, EarlyView.Abstract As habitat salinity markedly differs between the endangered, freshwater‐dwelling Saimaa ringed seal (Pusa saimensis Nordquist, 1899) and the brackish water‐inhabiting Baltic ringed seal (Pusa hispida botnica Gmelin, 1788), we investigated whether this difference has resulted in morphological changes to their kidneys.
