Metronidazole, chemically a nitroimidazole is an antiprotozoal drug, which has broad spectrum cidal activity against anaerobic protozoa, anaerobic and microaerophillic bacteria. It was introduced in 1959 for trichomoniasis, and later found to be highly active amoebicide. Metronidazole after entering the cell by diffusion, its nitro group is reduced by certain redox proteins to a highly reactive...

The present study was conducted with an objective to clinically assess rural school going children in the Rural Area of Bhilwara District. The study was conducted in village Hurda of Hurdapanchayatsamiti in Bhilwara district of Rajasthan. A total of 120 school going children (15 girls and 15 boys from each school) were selected. In the Clinical assessment, respondents revealed, an equal number ...

We study the angular momentum (AM) of the arbitrary superposition of counterpropagating paraxial beams that have the same magnitude of the wavenumber. We derive compact analytical expressions for the total AM in a transverse cross section (linear AM density) and the total AM flux through the cross section. We demonstrate that whereas for the time-averaged linear AM density its separation into t...

introduction: according to the prevalence of sore mouth, its outcome and possible role of anemia in its etiology and some contradictions in this theory, our study was performed to evaluate the role of iron deficiency anemia as a etiological factor for sore mouth. materials and methods: this historical cohort study was performed on 40 cases, including 20 anemic patients as the experimental group...

BACKGROUND Down syndrome (DS) is the most common chromosomal abnormality affecting numerous organs, including the orofacial region. The objective of the present study was to assess the prevalence of lip and oral soft tissue lesions, with particular emphasize on the incidence of fissured tongue, lip fissures and angular cheilitis, among individuals with DS in Yemen. MATERIAL AND METHODS This c...

When linearly polarised light is transmitted through a spinning window, the plane of polarisation is rotated. This rotation arises through a phase change that is applied to the circularly polarised states corresponding to the spin angular momentum (SAM). Here we show an analogous effect for the orbital angular momentum (OAM), where a differential phase between the positive and negative modes (±...

We present a general theory of spin-to-orbital angular momentum (AM) conversion of light in focusing, scattering, and imaging optical systems. Our theory employs universal geometric transformations of non-paraxial optical fields in such systems and allows for direct calculation and comparison of the AM conversion efficiency in different physical settings. Observations of the AM conversions usin...
