ANATOMICAL DISPOSITION OF CARPAL BONES OF GOLDEN RETRIEVER DOG BY X-RAY EXPOSURE
The present study was conducted to know the general disposition of bones in carpal region of experimental dogs by X-ray study with an objective that the findings will facilitate to have an in-depth knowledge about the proper positioning of the carpal bones for surgical management of fractures and different types of bone deformities in dogs. In the present study, the anatomical disposition and arrangement pattern of carpal bones playing a pivotal role in providing
the structural conformity in the limbs of Golden Retriever dog has been thoroughly confirmed by Xray exposure
Critical behavior in the variation of GDR width at low temperature
We present the first experimental giant dipole resonance (GDR) width
systematics, in the temperature region 0.8 1.2 MeV for Tl, a
near Pb nucleus, to investigate the evolution of the GDR width in shell effect
& pairing dominated region. The extracted GDR widths are well below the
predictions of shell effect corrected thermal shape fluctuation model (TSFM)
and thermal pairing included phonon damping model. A similar behavior of the
GDR width is also observed for Cu measured in the present work and
Sb, measured earlier. This discrepancy is attributed to the GDR induced
quadrupole moment leading to a critical point in the increase of the GDR width
with temperature. We incorporate this novel idea in the phenomenological
description based on the TSFM for a better understanding of the GDR width
systematics for the entire range of mass, spin and temperature.Comment: Accepted for publication in Phys. Lett. B, 7 pages, 4 figure
Pathology of Eupatorium adenophorum (Sticky snakeroot) toxicity in mice
The leaves of Eupatorium adenophorum Spreng were powdered and extracted with methanol. An acute oral toxicity study was conducted in male Swiss albino mice and a LD50 of 3501 mg/kg was obtained during 14 days observation period. Twenty Swiss albino mice (male) randomly divided into four groups were administered orally with vehicle (5% tween 80), 1/20th (i.e. 175 mg/kg), 1/10th (i.e. 350 mg/kg) and 1/5th (i.e. 750 mg/kg) LD50 doses of methanolic leaf extract of E. adenophorum Spreng; respectively for a period of 30 days. The mice were sacrificed on day-31 and the liver dissected out freed from adherent tissue weighed to nearest milligram. The liver histology, estimations of biochemical contents and enzyme activities were carried out. Treatment of the mice with methanolic extract of E. adenophorum at the dose level of 750 mg/kg (i.e. 1/5th LD50) elicited hepatotoxicity and the animals had yellow discoloration of liver, subcutaneous tissue and musculature indicating jaundice. Study on liver enzymes revealed marked increase in the activities of alkaline phosphatase (ALP), alanine transaminase (ALT), aspartate transaminase (AST) and lactate dehydrogenase (LDH), while significant increase in serum bilirubin level. Histopathological examination of the livers of the group IV animals had focal areas of necrosis and bile duct proliferation. Elevation in plasma bilirubin concomitant with alterations in enzyme profile and histopathological lesions are consistent with liver injury and cholestasi
Particle density fluctuations
Event-by-event fluctuations in the multiplicities of charged particles and
photons at SPS energies are discussed. Fluctuations are studied by controlling
the centrality of the reaction and rapidity acceptance of the detectors.
Results are also presented on the event-by-event study of correlations between
the multiplicity of charged particles and photons to search for DCC-like
signals.Comment: Talk presented at Quark Matter 2002, Nantes, Franc
Tick-borne ehrlichiosis infection in human beings
Human monocytic ehrlichiosis is a tick-borne infectious disease transmitted by several tick species, especially Amblyomma spp caused by Ehrlichia chaffeensis. E. chaffeensis is an obligatory intracellular, tick-transmitted bacterium that is maintained in nature in a cycle involving at least one and perhaps several vertebrate reservoir hosts. Two additional Ehrlichia spp, Anaplasma (formerly Ehrlichia) phagocytophila (the agent of human granulocytic ehrlichiosis [HGE]) and E. ewingii (a cause of granulocytic ehrlichiosis in dogs) act as human pathogens. Human E. chaffeensis infections have generally been reported in North America, Asia and Europe, but recently human cases have been reported in Brazil only. Human monocytic ehrlichiosis is diagnosed by demonstration of a four-fold or greater change in antibody titer to E. chaffeensis antigen by IFA in paired serum samples, or a positive PCR assay and confirmation of E. chaffeensis DNA, or identification of morulae in leukocytes and a positive IFA titer to E. chaffeensis antigen, or immunostaining of E. chaffeensis antigen in a biopsy or autopsy sample, or culture of E. chaffeensis from a clinical specimen
