Double-barreled O2 microelectrodes were used to study O2 diffusion and consumption in the superfused drone (Apis mellifera) retina in darkness at 22 degrees C. Po2 was measured at different sites in the bath and retinas. It was found that diffusion was essentially in one dimension and that the rate of O2 consumption (Q) was practically constant (on the macroscale) down to Po2 s less than 20 mm ...

background: we aimed to develop and validate the persian version of short form mcgill pain questionnaire-2 (sf-mpq-2) in patients with knee osteoarthritis. methods: translation and back translation was performed using beaton’s guideline. after a consensus has achieved on the persian version of sf-mpq-2, it was administered to 30 patients with knee osteoarthritis in a pilot study. then, we enrol...

We calculate the O(a) improvement coefficient for the axial-vector current using the nonperturbative method proposed by the LANL group. Results for the coefficient in the range β = 5.93 to 6.2 are presented. We find cA is close to the 1-loop tadpole-improved perturbative value. In addition, scaling of the pseudoscalar decay constant and renormalised quark mass is improved compared to that obtai...

We wanted to determine whether cell populations and soluble components in bronchoalveolar lavage (BAL) could be useful in predicting the outcome of lung function and chest radiography in patients with untreated pulmonary sarcoidosis. Analysis of soluble proteins in BAL fluid, included the levels of immunoglobulins and the two major antiproteases, alpha 2-macroglobulin (alpha 2-M) and alpha 1-pr...

We evaluated whether tumor necrosis factor (TNF)-alpha induces an increase in permeability of an alveolar epithelial monolayer via gelatinase secretion and basement membrane degradation. Gelatinase secretion and epithelial permeability to radiolabeled albumin under unstimulated and TNF-alpha-stimulated conditions of an A549 human epithelial cell line were evaluated in vitro. TNF-alpha induced b...

The tree-level string effective action is known to contain quartic Riemann terms with coefficient $\zeta(3)\alpha'^3$. In the case of type II this first $\alpha'$ correction. We use requirement that reduced on a $d$-torus should have an $O(d,d)$ symmetry find B-field couplings up fifth order in fields. answer turns out surprisingly intricate structure.

In this study we examined changes in the large-scale structure of resting-state brain networks in patients with Alzheimer's disease compared with non-demented controls, using concepts from graph theory. Magneto-encephalograms (MEG) were recorded in 18 Alzheimer's disease patients and 18 non-demented control subjects in a no-task, eyes-closed condition. For the main frequency bands, synchronizat...

The $\alpha$-$T_3$ lattice, an interpolation model between the honeycomb lattice of graphene($\alpha=0$) and dice lattice($\alpha=1$), undergoes a topological phase transition across $\alpha=1/\sqrt{2}$ when exposed to circularly polarized off-resonant light. We study Berry mediated bulk magnetic anomalous thermoelectric responses in order capture signatures driven lattice. It is revealed that ...

background: particular circumstances in the intensive care unit have led the patients to experience significant levels of pain and discomfort. on the other hand, these patients cannot express their discomfort due to several reasons. aim: to develop the causes of discomfort in the intensive care units. methods: in order for assessing the causes of discomfort, the initial questionnaire was extrac...
