Epstein Barr virus induced pneumonitis: a rare entity in immunocompetent baby

Acute infectious interstitial pneumonitis (IP) (Epstein Barr virus (EBV)-associated IP) in children has been most commonly associated with human immunodeficiency virus (HIV) infection and immunocompromised hosts. Here we report a case of EBV-associated interstitial pneumonitis with cervical lymphadenopathy in an immunocompetent child. Patient underwent extensive routine and serologic workup which revealed positive polymerase chain reaction (PCR) for EBV, pointing towards the diagnosis of EBV induced pneumonitis. It is a very rare entity and is hardly seen among immunocompetent individuals especially young children. The aim of this case report is to bring to our notice that among all described pneumonias, EBV induced pneumonitis can be a possibility while dealing with lung infections

ETHNOBOTANY IN RELATION TO LIVELIHOOD SECURITY IN DISTRICT BASTAR OF CHHATTISGARH STATE WITH SPECIAL REFERENCE TO NON -TIMBER FOREST PRODUCES

In present study ethnobotany in relation to livelihood security in district Bastar of Chhattisgarh state with special reference to non timber forest produces were found to collect variety of plant produces from forests, for their livelihood security. Those collected plant produces were non timber forest produces (NTFPs).In this research total 44 plants producing NTFP were noted to be collected by tribals in 20 villages of Bastar district.Plant and plant produce collected  by the tribals from the plants were seeds of 11 plants, fruits of 11, roots of 03, Rhizomes of 04,flowers of 04, secretory products from 03 plants, while 04 whole plants.Lakh and cocoons were also collected by the tribals from the forest.Beside collection of NTFPs,69 potential market place in Bastar district, where marketing of NTFPs was found maximum were also identified for the selling of plant produces

Mineralogical studies on 5 plastic fire clays - DTA, TG and electron-microscopy

Mineralogical studies on five plastic fire clays of India have been carried out by DTA, TG and electron microscopy. Studies were done on both `as received' and `<1-mu fraction' of clays. Results indicated that all the clays were predominantly kaolinite in nature and showed the main endothermic peak between 540-degrees and 590-degrees-C and the exothermic peak between 920-degrees and 985-degrees-C. A large exothermic peak at 810-degrees-C and a weight loss of 5.35% between 700-degrees and 900-degrees-C in case of Barachatarma clay indicated the presence of graphitic carbon in the same. Both Neyveli and Badampahar clays contained illite and goethite. Electron micrographs of Mohuamilan and Neyveli clays showed hexagonal flakes of well-ordered kaolinite. Some tubular particles were seen in Chittorpur, Neyveli and Badampahar clays in addition to the kaolinite particles

Preparation of Y-PSZ ceramics from commercial grade zirconia powder

Yttria—partially stabilized zirconia (Y—PSZ) ceramics containing 3.5, 4.0 and 5.0 mol% Y2O3 were fabricated from commercial grade zirconia powder by dry pressing and normal sintering at 1600°C. The mechanical properties and microstructures of such materials were examined. Mechanical properties, both strength and fracture toughness, deteriorated with increasing yttria content. XRD revealed the presence of both tetragonal and monoclinic phases in the sintered materials and with decreasing yttria content, the tetragonal phase increased. Vickers' microhardness values differed slightly among the three compositions

Influence of powder preparation on the mechanical properties of partially stabilized zirconia

The effect of method of powder preparation on the mechanical properties of partially stabilized zirconia has been studied. Zirconia powder doped with 3 mol% of yttria was prepared by three different methods, viz. mechanical method, modified mechanical method and co-precipitation method. It has been observed that fracture toughness, transverse rupture strength, microhardness etc improved with the improvement in the powder preparation method

Fabrication and characterization of porous hydroxyapatite ocular implant followed by an in vivo study in dogs

Porous hydroxyapatite ocular implant was fabricated by a novel and simple method using hydroxyapatite powder synthesized in the laboratory. The porosity and pore size of the implant were controlled to make it light in weight as well as suitable for rapid vascularization after implantation. The implant was characterized by X-ray diffraction studies, infrared spectra and chemical analysis for phase purity and chemical composition. The pore morphology and pore size distribution of the samples were investigated by scanning electron microscope (SEM). Thereafter, efficacy of the implant was examined by in vivo study in dogs. Clinical, haematological and radiological studies indicated the suitability of the implant for replacement of the lost eye of human patients
