OBJECTIVE We investigated the proliferative activities in premalignant laryngeal vocal chord lesions treated by epithelial stripping in microlaryngoscopy, using immunohistochemical staining with anti-p53, anti-PCNA and anti-Ki-67 monoclonal antibody and we correlated with clinic and morphologic aspects. MATERIAL AND METHODS The study was made on 32 patients hospitalized in Craiova ENT Clinic ...

Introduction Infertility is a condition that affects a couple and is defined as the lack of conception after an arbitrary period of 12 months with regular sexual intercourse and without using any contraception. Infertility is a common medical problem present in about 10% of couples in reproductive age. Tubal factor infertility (TFI) is one of the leading causes of infertility in the world inclu...

Enamel is one of the most important structures of the tooth, both from a functional and esthetic point of view. Primary enamel carries registered information regarding metabolic and physiological events that occurred during the period around birth and the first year of life. Detailed knowledge of normal development and the structure of enamel is important for the assessment of mineralization de...

The sternal gland of primitive termites of the genus Zootermopsis (Z. nevadensis or Z. angusticollus) (Hagen) seems more organized than that of higher termites, in being comprised of three cell layers. It is also studded with about 200 campaniform sensilla. Below the meshwork cuticle of the gland lies a layer of columnar epithelial cells whose apical surfaces form a brush border, and whose basa...

Drosophila melanogaster is a cosmopolitan species that colonizes a great variety of environments. One trait that shows abundant evidence for naturally segregating genetic variance in different populations of D. melanogaster is cold tolerance. Previous work has found quantitative trait loci (QTL) exclusively on the second and the third chromosomes. To gain insight into the genetic architecture o...

This paper demonstrates the modelling of morphological knowledge in Bulgarian and applications of the created data sets in an integrated framework for production and manipulation of language resources. The production scenario is exemplified by the Bulgarian verb as the morphologically richest and most problematic part-of-speech category. The definition of the set of morphosyntactic specificatio...

PURPOSE To evaluate tympanic bulla healing after experimental ventral osteotomy in cats. METHODS Twenty adult cats were submitted to unilateral ventral bulla osteotomy and divided into two groups: cats of A1 group (n=10) were euthanized at 8 weeks and cats of A2 group (n=10), at 16 weeks postoperative. RESULTS Signs of Horner's syndrome or damage to the inner ear were not found. Open-mouth ...

Ultrastructural studies of cytoplasmic droplets of the spermatozoa of bulls, rams, rabbits, rats (Bloom & Nicander, 1961) and bats (Fawcett & Ito, 1965) revealed only numerous membranous vesicles and tubules in the matrix of the droplets. These authors agreed that the membranous elements were probably of endoplasmic reticulum and/or Golgi complex origin. The simplicity of the ultrastructure and...
