Toroviruses are recognized enteric pathogens of cattle and horses; in humans, similar pleomorphic particles have been described, but doubt has been raised concerning their identity as viruses. We screened fecal samples from humans with diarrhea for the presence of torovirus-like particles (TVLPs) by electron microscopy and subsequently used an enzyme-linked immunosorbent assay (ELISA) with bovi...

Acroangiodermatitis (AAD), also known as Pseudo-Kaposi’s sarcoma, is a rare benign angioproliferative disease associated with chronic venous insufficiency (CVI) or other vascular disorders. We present an 81-year-old male with plaque-like cutaneous lesions, which had progressive erythematous margins, severe pain, and intense pruritus, as well as bilateral swollen and painful feet. It was around ...

The objectives of this study were to characterize change in surface properties of tetragonal zirconia polycrystals (TZP) after hydrophilic treatment, and to determine the effect of such changes on initial attachment of osteoblast-like cells. Roughened surfaces were produced by alumina-blasting and acid-etching. Hydrophilic treatment comprised application of immediately after blasting and acid-e...

The present study includes 50 patients symptomatic for tuberculous meningitis and 15 patients with meningitis other than tuberculosis The CSF specimens were subjected for ADA titer estimation, AFB smear preparation and molecular characterization by Nested-PCR for IS6110 gene. Out of 50 specimens 2 came AFB smear positive whereas 29 specimens came positive for Tuberculosis (TB) PCR and 21were ne...

Fatigue strength is largely affected by the influence of discontinuities: geometric notches like holes and corners in components, surface (roughness), pores inclusions material. Therefore fatigue structures materials a local problem calculations are best carried out using approaches such as stress concept, strain concept or fracture mechanical concepts. In this investigation, discontinuities on...

Twenty nine postcranial specimens of a Kenyapithecus species, discovered at Nachola during the field seasons 1984 and 1986, are described in detail. The specimens come from baboon-sized animals, with a baboon-like degree of sexual dimorphism in size. This species of Kenyapithecus was a predominantly arboreal animal, utilizing a combination of pronograde quadrupedalism and orthograde climbing an...

Bone loss may affect the structure of cancellous bone. But its effect on trabeculae with different characteristics, like rods and plates, is not accurately known. This study analyzes the effect of bone loss on individual rod-like and plate-like trabeculae. 94 specimens were obtained from mandibular condyles from both dentate and edentate humans and scanned with a micro-CT scanner. The bone volu...

Two cases of chronic giardiasis of the stomach diagnosed from gastric mucosal biopsy specimens are reported. The first case was associated with an acute-on-chronic gastritis and Helicobacter-like organisms, and the second with an adenocarcinoma of the stomach. In both cases the trophozoites had been missed in earlier biopsy specimens. As far as is known this is the first report of giardiasis of...

Corneal biopsy specimens from 3 patients with Cogan's microcystic corneal dystrophy were examined by light and electron microscopy. Specimens were taken from corneas showing microcysts, geographic or map-like areas, and refractile striae. In all samples there is a bilaminate subepithelial layer of fibrogranular material, the friability of which is probably the basis for recurrent erosions in th...
