We provide direct evidence that Bin/Amphiphysin/Rvs (BAR) family members bend the steady state membrane architecture of organelles in intact cells. In response to inducible BAR molecular actuators, organelles exhibit distinct changes to the orientation and degree of their membrane curvature. This rapidly inducible system may offer a mechanism by which to better understand the structure-function...
Using a large sample of D → Kπμν decays collected by the FOCUS photoproduction experiment at Fermilab, we present new measurements of two semileptonic form factor ratios: rv and r2. We find rv = 1.504 ± 0.057 ± 0.039 and r2 = 0.875 ± 0.049 ± 0.064. Our form factor results include the effects of the s-wave interference discussed in Reference [1].
Background & Aim: Increase in gastric residual volume and abdominal distention are important complications in patients with nasogastric tube feeding. This study aimed to determine the effect of local heat therapy on gastric residual volume and abdominal distention in patients with nasogastric tube feeding. Methods & Materials: In this double-blind clinical trial, 64 patients with nasogastric t...
Distribution of Residual Stresses in Polymer Reinforced Carbon Nanotubes and Laminated Carbon Fibers
In this study, the distribution of residual stress in fiber-reinforced nanocomposites is investigated. Fiber-reinforced nanocomposite is composed of three substances: carbon fiber, carbon nanotube (CNT), and polymer matrix. Unit cells in hexagonal packing array with different arrays as unit cell, 3*3 and 5*5 arrays have been selected as suitable for finite element analysis of residual stresses....

Background: Nutritional problems in premature newborns are of great importance for their development. In this regard, the neonatal positioning during and after feeding can have a significant effect on their nutritional tolerance. Therefore, the present study was conducted to compare the effect of two positions (i.e., prone and right lateral) on gastric residual volume ...
Results of investigations using various lung volumes for hydrostatic weighing determinations (HWD) appear to be inconclusive. Often, these lung volumes are predicted and not clinically determined. For this reason, total lung capacity (TLC), a measured residual volume (RV), and a predicted residual volume (PRV) were used during HWDs to compare the techniques. Twenty-five older men, 56 to 70 year...
Hydrostatic weighing (HW) was performed at both residual volume (RV) and functional residual capacity (FRC) to determine if underwater weighing at different lung volumes affected the measurement of body density. Subjects were 43 males, 18-25 yr. Subjects were submerged in the prone position, and the lung volume was measured by helium dilution at the time of the underwater weighing. Underwater w...
The postvoid residual volume (PVR) is a common urodynamic parameter used to quantify the severity of lower urinary tract dysfunction. However, the serial cystometrograms that are typically used to assess bladder function in animal models make measuring PVR very difficult. Current approaches are to either remove PVR after each void to measure it, which is disruptive to the bladder, or to neglect...
