We examined the liver of adult polar bears, arctic foxes, and rats by gold chloride staining, fluorescence microscopy for the detection of autofluorescence of vitamin A, hematoxylin-eosin staining, staining with Masson's trichrome, Ishii and Ishii's silver impregnation, and transmission electron microscopical morphometry. The liver lobules of the arctic animals showed a zonal gradient in the st...

Breast cancer is one of the most frequent malignancies in women, and its incidence is increasing. No reduction in the mortality rate has resulted from advances in early diagnosis and new therapeutic modalities; therefore, new approaches to the understanding of this disease are required. The observation that, in an experimental animal model, full-term pregnancy prior to exposure to a carcinogeni...

The asymmetric development of the cerebellum has been reported in several mammalian species. current study quantitatively characterized cerebellar asymmetry and sexual dimorphism cynomolgus macaques using magnetic resonance (MR) imaging-based volumetry. Three-dimensional T1W MR images at 7-tesla were acquired ex vivo from fixed adult male (n = 5) female monkey brains. Five transverse domains co...

The phytoestrogen has the positive effect in osteoporosis, cardiovascular diseases, facial flushing and other postmenopausal symptoms. And the purpose of this study was to evaluate the effect of phytoestrogen in increasing breast size clinically and histological. The result show meaningful augmentation of the breast in group taken phytoestrogen tablets (PEITO) and in mouse study, study group sh...

Different male germ cells identified on the basis of histological and cytological characteristics in the testicular lobules of Labeo rohita have been grouped into spermatogonia, primary spermatocytes, secondary spermatocytes, spermatids and spermatozoa. The seasonal changes of the testis in L. rohita have been described according to its morphological peculiarities as well as to its variations i...

Gryllophila cephalobulata n. sp. (Nematoda, Thelastomatidae) a parasite of the mole cricket Neocurtilla claraziana (Orthoptera, Gryllotalpidae) isolated in Buenos Aires Province, is described and illustrated. It is characterized by cuticle annulated all along the length of the body; the first ring has 4 lobules, the second one has 14 lobules, the others rings are simple, the stoma is short and ...

Autologous fat injection has been widely used during the past 20 years to correct contour anomalies. We have been using suction-assisted lipectomy for the past 13 years, and we have used the aspirated fat to correct contour irregularities on several occasions. We present the case of a 44-year-old woman who, after autologous fat transplantation to correct a contour anomaly (depression secondary ...

Autism is a neurologic disorder that severely impairs social, language, and cognitive development. Whether autism involves maldevelopment of neuroanatomical structures is not known. The size of the cerebellar vermis in patients with autism was measured on magnetic resonance scans and compared with its size in controls. The neocerebellar vermal lobules VI and VII were found to be significantly s...
