Why Do Tetrapropylammonium Chloride and Sulphate Salts Destabilize the Native State of Globular Proteins?

open access: yesThe Scientific World Journal, 2014
It has recently been shown that aqueous solutions of tetrapropylammonium chloride and sulphate salts destabilize the folded conformation of Trp-peptides (Dempsey et al., 2011). This result is rationalized by the application of a statistical thermodynamic

Observed crowding effects on Mycobacterium tuberculosis 2-trans-enoyl-ACP (CoA) reductase enzyme activity are not due to excluded volume only

open access: yesScientific Reports, 2017
The cellular milieu is a complex and crowded aqueous solution. Macromolecular crowding effects are commonly studied in vitro using crowding agents. The aim of the present study was to evaluate the effects, if any, of macromolecular synthetic crowding ...

Probing the effect of PEG-DNA interactions and buffer viscosity on tethered DNA in shear flow.

open access: yesPLoS ONE
DNA flow-stretching is a widely employed, powerful technique for investigating the mechanisms of DNA-binding proteins involved in compacting and organizing chromosomal DNA. We combine single-molecule DNA flow-stretching experiments with Brownian dynamics

Endoscopic evacuation vs. stereotactic aspiration for the treatment of supratentorial intracerebral hematoma: A comparative study

open access: yesJournal of Stroke and Cerebrovascular Diseases
Background: Endoscopic surgery (ES) and stereotactic aspiration (SA) are minimally invasive surgical techniques. This study was conducted to investigate the differences between ES and SA in terms of perioperative perihematomal edema (PHE) and evaluate ...

Enhancement of Lysozyme Crystallization Using DNA as a Polymeric Additive

open access: yesCrystals, 2019
This study reports the first experimental evidence of using DNA as a polymeric additive to enhance protein crystallization. Using three kinds of DNA with different molecular weights—calf DNA, salmon DNA, and herring DNA—this study showed an ...

Reproductive factors and brain volume in community-dwelling individuals: the Ohasama Study

open access: yesEnvironmental Health and Preventive Medicine
Background: Reproductive history can be conceptualized as a life-course exposure integrating biological and social factors. Although reproductive factors have been associated with stroke risk and cognitive function, their relationships with structural ...

Evaluation of the changes in hydrogel spacer volume in patients treated with proton therapy for prostate cancer

open access: yesBMC Urology
Background Rectal bleeding is a recognized late complication of radiation therapy in the treatment of prostate cancer, and hydrogel spacers have been used to prevent this adverse effect. Previous reports have indicated that the volume of hydrogel spacers

Impact of bladder volume on renal pelvis dimensions in pediatric hydronephrosis

open access: yesTrends in Pediatrics
Objective: To evaluate the effect of pre-void and post-void bladder volume on the anteroposterior (AP) diameter of the renal pelvis in asymptomatic pediatric hydronephrosis and to determine its influence on ultrasonographic measurement variability ...

Effect of transjugular intrahepatic portosystemic shunt on platelet count and exact spleen volume segmented on computed tomography

open access: yesActa Radiologica Open
Background Transjugular intrahepatic portosystemic shunt (TIPS) is effective for portal decompression, but its effect on splenic congestion is not proven. Platelet changes and spleen size following TIPS are controversially reported while the exact volume
