Molecular dynamics computer simulations are used to study the aging dynamics of SiO2 (modeled by the BKS model). Starting from fully equilibrated configurations at high temperatures Ti∊{5000 K,3760 K}, the system is quenched to lower temperatures Tf∊{2500 K,2750 K,3000 K,3250 K} and observed after a waiting time tw. Since the simulation runs are long enough to reach equilibrium at Tf, we are ab...

Morphometric characters are important to estimate the population of crustacean species. In the present study, relationships between various morphometric characters of the freshwater crab Sodhiana iranica was studied at Eelood freshwater spring of southern Iran. Crabs were collected randomly from April 2012 to April 2013 bimonthly. A total of 69 (43.67%) females and 89 (56.32%) males were col...

This study was conducted to investigate the effect of tofu wastewater (TW) addition to the growth medium on the growth of Spirulina platensis. The TW addition was varied in range of 0 – 8 %v/v. The results showed that the growth rate (μ) of S. platensis at TW addition of 0, 2, 4, 6, 8 %v/v was 0.007, 0.084, 0.074, 0.088, 0.086 mg/L/d, respectively. The medium with TW content of 6 %v/v (carbon:n...

BACKGROUND Diaphragm strength can be assessed by the measurement of gastric (TW PGA), oesophageal (TW POES), and transdiaphragmatic (TW PDI) pressure in response to phrenic nerve stimulation. However, this requires the passage of two balloon catheters. A less invasive method of assessing diaphragm contractility during stimulation of the phrenic nerves would be of clinical value. A study was und...

The clinical application of transdiaphragmatic twitch pressure (Pdi,tw) response to phrenic nerve stimulation has been hindered by the requirement for placement of oesophageal and gastric balloons. Investigators have reported that mouth twitch pressure (Pmo,tw) estimates Pdi,tw accurately at lung volumes above and below functional residual capacity (FRC). However, it is not known whether Pmo,tw...

Background: In critically ill patients inspiratory muscle function may be assessed by measurements of maximal inspiratory airway pressure and the response of twitch transdiaphragmatic pressure (Pdi tw) to bilateral phrenic nerve stimulation. The first is limited by its total dependence on patient cooperation. Although the second approach is independent of patient volition, it is impractical bec...

TW-37 is a novel, potent and non-peptide Bcl-2 small-molecule inhibitor. Its activity in colorectal cancer (CRC) cells is studied. In both HCT-116 cells and primary human colon cancer cells, treatment with TW-37 at only nM concentration efficiently inhibited cell survival and proliferation. TW-37 also induced caspase-3/9 and apoptosis activation in CRC cells. Feedback autophagy activation was o...
