the effect of chronic inflammation induced by complete freund's adjuvant (cfa) on anterior blood vessels of knee joint and its diameter was studied. blood flow changes in response to phenylephrine (αl-adrenoceptor agonist) in cfa-treated and contralateral knee joints were observed over a 40-day period, using laser doppler flowmetery (ldf) technique. unilateral injection of cfa (0.2 ml) inc...

A combination of template-assisted metal catalytic etching and self-limiting oxidation has been successfully implemented to yield core-shell silicon nanowire arrays with inner diameter down to sub-10 nm. The diameter of the polystyrene spheres after reactive ion etching and the thickness of the deposited Ag film are both crucial for the removal of the polystyrene spheres. The mean diameter of t...

In 1978, Chvátal and Thomassen proved that every 2-edge-connected graph with diameter 2 has an orientation with diameter at most 6. They also gave general bounds on the smallest value f(d) such that every 2-edge-connected graph G with diameter d has an orientation with diameter at most f(d). For d = 3, their general bounds reduce to 8 ≤ f(3) ≤ 24. We improve these bounds to 9 ≤ f(3) ≤ 11.

Objective The feasibility and usefulness of transradial catheterization for coronary and neuro-intervention are well known. However, the anatomical change in the catheterized radial artery (RA) is not well understood. Herein, we present the results of ultrasonographic observation of the RA after routine transradial cerebral angiography (TRCA). Methods Patients who underwent routine TRCA with ...

The effect of chronic inflammation induced by complete Freund's adjuvant (CFA) on anterior blood vessels of knee joint and its diameter was studied. Blood flow changes in response to phenylephrine (αl-adrenoceptor agonist) in CFA-treated and contralateral knee joints were observed over a 40-day period, using laser Doppler flowmetery (LDF) technique. Unilateral injection of CFA (0.2 ml) increase...

Acute exposure to environmental tobacco smoke (ETS) is considered to adversely influence atherogenesis. The aim of this article was to assess whether brachial ultrasonography in subjects with endothelial dysfunction after ETS exposure is associated with atherosclerotic lesions. Never smoker healthy volunteers (n = 18) and subjects with a previous myocardial infarction (MI; n = 10) were studied....

The growth and development of teratocytes was examined in the Cotesia kariyai-Pseudaletia separata system. Cotesia kariyai embryos released an average of 163 teratocytes at the time of hatching, 3.5 days after oviposition. The cells increased in diameter from 30 to 77 µm until 7 days post-parasitization, after which there was no significant increase in average diameter. However, there was signi...

Two hundred forty consecutive patients with acute myocardial infarction treated within 48 hours by successful percutaneous transluminal coronary angioplasty (PTCA) were analyzed to determine the incidence and predictors of recurrent ischemic events during hospitalization. Thirty-nine patients had recurrent ischemia: 20 patients had chest pain or electrocardiographic changes requiring repeat PTC...

The intraradical portion of arbuscular mycorrhizal (AM) fungi comprises mycelium, vesicles, and special physiological interfaces termed arbuscules; sometimes mycorrhizal fungi also produce spores within their hosts. Arbuscules are ephemeral structures that collapse after a few days, while the hyphae and vesicles appear to remain intact for some time after arbuscule senescence (post-arbuscule st...
