Hybrid Metal–Boron Diatomic Site In article number 2104445, Wei An and co-workers demonstrate the validity of a novel hybrid atomic site which is able to promote CO2 electroreduction (CO2RR). Besides carbon-affinity metal, electronic spin state metal can also play an important role in modulating selectivity C–C coupling CO2RR.

Immature mosquito development and survival of adults are highly sensitive to environmental temperature, which can alter gene expression during the mosquito life-cycle. To further understand how heat shock proteins are developmentally expressed in mosquitoes, we subjected Þrst instar larvae, 16-h old pupae and female of Aedes aegypti (L.) (Diptera: Culicidae) to heat shock treatment for 0, 15, 3...

background : immunogenicity of streptokinase (stk), as a thrombolytic drug, have limited its clinical use. elimination of the amino acid residues that are responsible for immunogenicity while don’t affect the bioactivity of stk is worthy. recently, we modified the stk through elimination of 42 amino acids from its’ c-terminal and assessed its bioactivity in vitro . objective : in this study, bi...

gamma aminobutyric acid (gaba) is one of the inhibitory neurotransmitters that may have the ability torelieve the intensity of stress. heat stress remains a major threat for duck production in summer in most areas of china. the current study was conducted to investigate the effect of dietary gaba on performanceparameters and plasma metabolites of heat exposed ducks. two thousand cherry valley d...

Cutaneous hyperemia in response to rapid skin local heating to 42°C has been used extensively to assess microvascular function. However, the response is dependent on both nitric oxide (NO) and endothelial-derived hyperpolarizing factors (EDHFs), and increases cutaneous vascular conductance (CVC) to ∼90-95% maximum in healthy subjects, preventing the study of potential means to improve cutaneous...

In experiments with the K strain of Staphylococcus aureus and the K race of bacteriophage suspended in tryptose phosphate broth and maintained at 42 degrees C. it was found that the presence of 1 M NaCl produced certain drastic changes in the relationship between the host cells and the infecting virus: 1. Staphylococci grown at 42 degrees C. in plain broth or in NaCl-broth are "activated," i.e....
