Sir, We read with great interest the article on “Comparison of potassium hydroxide mount and mycological culture with histopathological examination using periodic acid-Schiff staining of nail clippings” in a recent issue of IJDVL.[1] The authors’ findings about high sensitivity of periodic acid-Schiff (PAS) staining in the diagnosis of onychomycosis is consistent with previous studies on the su...

We derive a Hamiltonian version of the PT-symmetric discrete nonlinear Schrödinger equation that describes synchronized dynamics of coupled pendula driven by a periodic movement of their common strings. In the limit of weak coupling between the pendula, we classify the existence and spectral stability of breathers (time-periodic solutions localized in the lattice) supported near one pair of cou...

vanadium supported on highly ordered nanoporous silica (vox-lus-1) was synthesized and characterized by xrd, nitrogen adsorption‑desorption isotherms and uv-visible spectrophotometer. direct oxidation of benzene to phenol in liquid phase by h2o2 peroxide were examined by using various solvents (methanol, acetone, acetic acid, acetonitryl). the maximum yield (25%) and selectivity (73%) of the ph...

objective(s) oxidative stress plays an important role in diabetic nephropathy pathogenesis. rosmarinic acid, a plant phenolic compound, was first used as an antioxidant agent for inhibition of diabetic nephropathy. material and methods forty male rats were uninephrectomized from the left flank.the rats were divided in four groups randomly; group one as control, group two diabetic untreatment, g...

We demonstrate that the introduction of a subwavelength periodic modulation into a metallic structure strongly modifies the guiding characteristics of the surface plasmon modes supported by the system. Moreover, it is also shown how a new type, to our knowledge, of a tightly confined surface plasmon polariton mode can be created by just milling a periodic corrugation into a metallic ridge place...

In this paper, the dynamic stability analysis of a simply supported beam carrying a sequence of moving masses is investigated. Many applications such as motion of vehicles or trains on bridges, cranes transporting loads along their span, fluid transfer pipe systems and the barrel of different weapons can be represented as a flexible beam carrying moving masses. The periodical traverse of masses...

AIMS To compare the efficacy of histochemical and immunohistochemical methods in detecting forms of Sporothrix schenckii in tissue. METHODS Thirty five cutaneous biopsy specimens from 27 patients with sporotrichosis were stained by histochemical haematoxylin and eosin, periodic acid Schiff, and Gomori's methenamine silver methods and an immunohistochemical (avidin-biotin complex immunoperoxid...

In this study, we aimed to determine whether skeletal muscle cells per se are a source of interleukin (IL)-6 during contraction and whether IL-6 production is fiber type specific. Muscle biopsy samples were collected from seven males before (PRE) and after (POST) completing 120 min of continuous bicycle ergometry. Biopsies were sectioned and analyzed for the following: IL-6 protein detected by ...

REDUCTION IN THE MEAN AMOUNT of periodic acid-Schiff reactive material ( PASMa ) in neutrophil leukocytes from patients with chronic myelocytic leukemia ( CML ) has previously been noted with semiquantitative “score” methods.’m The PASMa studied in these investigations proved to be digestible with saliva or diastase and was therefore considered to consist of glycogen. So far, no attempt has bee...
