Water Stable Isotopes in Ecohydrological Field Research: Comparison Between In Situ and Destructive Monitoring Methods to Determine Soil Water Isotopic Signatures

open access: yesFrontiers in Plant Science, 2020
Ecohydrological isotope based field research is often constrained by a lack of temporally explicit soil water data, usually related to the choice of destructive sampling in the field and subsequent analysis in the laboratory.

The influence of rotor type and centrifugation time on the yield and purity of extracellular vesicles

open access: yesJournal of Extracellular Vesicles, 2014
Background Extracellular vesicles (EV), the collective term for vesicles released from cells, consist of vesicle species ranging in size from 30 nm to 5 µm in diameter.

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

open access: yesMolecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Design of a Centrifugal Blood Pump: Heart Turcica Centrifugal

open access: yesArtificial Organs, 2011
AbstractA prototype of a new implantable centrifugal blood pump system named Heart Turcica Centrifugal (HTC) was developed as a left ventricular assist device (LVAD) for the treatment of end‐stage cardiac failure. In the development of HTC, effects of blade height and volute tongue profiles on the hydraulic and hemolytic performances of the pump were ...

KDM7A and KDM1A inhibition suppresses tumour promoting pathways in prostate cancer

open access: yesMolecular Oncology, EarlyView.
Treatment resistance is a major challenge for patients with advanced prostate cancer. This study examined an alternative approach to target the major prostate cancer‐promoting pathway by targeting epigenetic factors, whose levels are higher in tumours.

Effect of treatments and washing cycles on the quality of Nile tilapia (Oreochromis niloticus) protein concentrate

open access: yesJournal of Fisheries, 2017
The extraction of proteins from wastes reduces production costs and environmental pollution. The aim of this work was to evaluate the effect of two treatments involving decanting/sieving or centrifugation and the number of washing cycles on the quality ...

centrifugeR: Non-trivial balance of centrifuge rotors

open access: yes, 2022
Centrifuges are indispensable instruments in biology laboratories. For the safe operation of centrifuges, ensuring balance is a must. Loading test tubes in opposite holes and adding dummy tubes are far from the only ways to balance the centrifuge rotors.

Effect of cytological centrifugation on mitochondrial imaging with confocal microscopy.

open access: yes, 2013
(A) 3-dimensional top view and side profiles of untreated OV2008 cells, with and without cytological centrifugation prior to fixation. Yellow arrows indicate typical areas of separation that appear between mitochondria after centrifugation.

Transcriptional profiling of circulating extracellular vesicles from prebiopsy prostate cancer patients

open access: yesMolecular Oncology, EarlyView.
RNA profiling of circulating extracellular vesicles (EVs) from blood samples of men undergoing prostate biopsy identifies transcripts associated with clinically significant prostate cancer. Integrative analysis with public tumor datasets links EV‐derived gene signatures to tumor stage and progression‐free survival, highlighting CASP3, XRCC2, and RIT1 ...
