Effect of various dialysis modalities on intradialytic hemodynamics, tissue injury and patient discomfort in chronic dialysis patients: design of a randomized cross-over study (HOLLANT).

BMC Nephrol 2021 Apr 15;22(1):131. Epub 2021 Apr 15.

Department of Nephrology and Amsterdam Cardiovascular Sciences (ACS), Amsterdam UMC, VU University of Amsterdam, Amsterdam, The Netherlands.

Background: From a recent meta-analysis it appeared that online post-dilution hemodiafiltration (HDF), especially with a high convection volume (HV-HDF), is associated with superior overall and cardiovascular survival, if compared to standard hemodialysis (HD). The mechanism(s) behind this effect, however, is (are) still unclear. In this respect, a lower incidence of intradialytic hypotension (IDH), and hence less tissue injury, may play a role. Read More

Validation of Withings ScanWatch as a Wrist-Worn Reflective Pulse Oximeter: Hypoxia Study.

J Med Internet Res 2021 Apr 11. Epub 2021 Apr 11.

Withings, 2 rue Maurice Hartmann, Issy-Les-Moulineaux, FR.

Nickel(II) Complex with a Flexidentate Ligand Derived from Acetohydrazide: Synthesis, Structural Characterization and Hirshfeld Surface Analysis.

Acta Chim Slov 2020 Jun;67(2):516-521

The mononuclear Ni(II) complex [Ni(Lp)2(CH3OH)2]Cl2 has been synthesized by reacting 1-(5-hydroxy-3-methyl-5-phenyl-4,5-dihydro-1H-pyrazol-1-yl)ethan-1-one ligand (HL) with NiCl2·6H2O in methanol solution. In the reaction, the tridentate ligand, HL, was converted in situ into 4-hydroxy-4-phenylbut-3-en-2-ylidene)acetohydrazid ligand, (pyrazole, Lp).

Lasers Surg Med 2021 Apr 13. Epub 2021 Apr 13.

Universidade Nove de Julho, Rua Vergueiro 249, Liberdade, São Paulo, SP, 01504-001, Brazil.

Background And Objectives: Induction of myocardial infarction (MI) in rats by occlusion of the left anterior descending coronary artery is an experimental model used in research to elucidate functional, structural, and molecular modifications associated with ischemic heart disease. Photobiomodulation therapy (PBMT) has become a therapeutic alternative by modulating various biological processes eliciting several effects, including anti-inflammatory and pro-proliferative actions. The main objective of this work was to evaluate the effect of PBMT in the modulation of transcriptional and post-transcriptional changes that occurred in myocardium signal transduction pathways after MI.
