Do carboxyhemoglobin and methemoglobin levels predict the return of spontaneous circulation and prognosis of cardiac arrest patients?

Int J Clin Pract 2021 Jul 31:e14686. Epub 2021 Jul 31.

Department of Anesthesiology and Reanimation, Gulhane School of Medicine, University of Health Sciences, Ankara, Turkey, 06010.

Background: Early prediction of return of spontaneous circulation (ROSC) for cardiac arrest (CA) patients is a major challenge. Different biomarkers have been studied as an early predictor for ROSC, but a consensus has not been achieved in this regard. This study's goal was to investigate the value of the carboxyhemoglobin (COHb) and methemoglobin (MetHb) levels as a predictive marker for ROSC and prognostic marker for patients who achieve ROSC.

Pepper root rot resistance and pepper yield are enhanced through biological agent G15 soil amelioration.

PeerJ 2021 19;9:e11768. Epub 2021 Jul 19.

Institute of Plant Protection and Soil & Fertilizer, Hubei Academy of Agricultural Sciences, Wuhan, Hubei Provience, China.

Pepper root rot is a serious soil-borne disease that hinders pepper production, and efforts are being made to identify biological agents that can prevent and control pepper root rot. Our group recently discovered and produced a biological agent, named G15, which reduces the diversity and richness of fungi and bacteria when applied to pepper fields. In the soil of the G15-treatment condition, the pathogenic fungus was inhibited, while the richness of beneficial bacteria was increased. Read More

Sphingosine 1-phosphate Stimulates Insulin Secretion and Improves Cell Survival by Blocking Voltage-dependent K Channels in β Cells.

Front Pharmacol 2021 12;12:683674. Epub 2021 Jul 12.

Department of Pharmacology, Shanxi Medical University, Taiyuan, China.

Recent studies suggest that Sphingosine 1-phosphate (S1P) plays an important role in regulating glucose metabolism in type 2 diabetes. However, its effects and mechanisms of promoting insulin secretion remain largely unknown. Here, we found that S1P treatment decreased blood glucose level and increased insulin secretion in C57BL/6 mice. Read More

Effects of tea polyphenols on the activities of antioxidant enzymes and the expression of related gene in the leaves of wheat seedlings under salt stress.

Environ Sci Pollut Res Int 2021 Jul 28. Epub 2021 Jul 28.

School of Life Science, Northwest Normal University, Lanzhou, 730070, Gansu, People's Republic of China.

Longchun 30, a new wheat variety, was used to investigate seedling growth, element absorption, and antioxidant response under 150 mM NaCl and tea polyphenols (TP) (25 and 100 mg L) treatments alone or in combination, thus revealing TP-alleviating mechanism on the salt damage to plants. 150 mM NaCl stress alone inhibited the seedling growth, increased sodium content and reactive oxygen species (ROS) accumulation, but reduced potassium (K) and calcium (Ca) levels at different culture times, thus resulting in the oxidative damage to the leaves. Even though 25 or 100 mg L TP treatment alone led to the significant increases of O and HO generation, TP-treated leaves exhibited the reduction of relative electrical conductivity and no change of malondialdehyde content.

Mechanisms and management of drug-induced hyperkalemia in kidney transplant patients.

Rev Endocr Metab Disord 2021 Jul 22. Epub 2021 Jul 22.

Department of Medicine, Division of Nephrology, Hypertension and Kidney Transplantation, School of Medicine, University of California, CA, Irvine, Orange, USA.

Hyperkalemia is a common and potentially life-threatening complication following kidney transplantation that can be caused by a composite of factors such as medications, delayed graft function, and possibly potassium intake. Managing hyperkalemia after kidney transplantation is associated with increased morbidity and healthcare costs, and can be a cause of multiple hospital admissions and barriers to patient discharge. Medications used routinely after kidney transplantation are considered the most frequent culprit for post-transplant hyperkalemia in recipients with a well-functioning graft. Read More

Novel lncRNA lncRNA001074 participates in the low salinity-induced response in the sea cucumber Apostichopus japonicus by targeting the let-7/NKAα axis.

Cell Stress Chaperones 2021 Jul 21. Epub 2021 Jul 21.

Key Laboratory of Mariculture & Stock Enhancement in North China's Sea, Ministry of Agriculture, Dalian Ocean University, Heishijiao Street, No. 52, Dalian, 116023, China.

Salinity fluctuations have severe impacts on sea cucumbers and therefore important consequences in sea cucumber farming. The responses of sea cucumbers to salinity changes are reflected in the expression profiles of multiple genes and non-coding RNAs (ncRNAs). The microRNA (let-7) which is a developmental regulator, the ion transporter gene sodium potassium ATPase gene (NKAα), and the long ncRNA lncRNA001074 were previously shown to be involved in responses to salinity changes in various marine species.
