BACKGROUND: The growth and differentiation of skeletal pectoral limb girdle, wing and the ossification centers in these regions after hatching were investigated in some groups of quails. OBJECTIVES: The aim of this study was to determine the age of physical maturity and radiological and histological assessment of the ossification centers of pectoral limb in quail. METHODS: 14 quails after hatch...

Carcinoma of the larynx is one of the commonest malignant tumours of the upper respiratory system.The main objective of this study was to highlight the histological pattern and evaluate the occurrence of the malignant tumours of the larynx. This was a retrospective study involving 146 patients aged between 36 to 77 years with an average age of 59.7 years. Patients with symptoms and signs of lar...

We report an unusual case of alpha-fetoprotein (AFP)-producing gastric carcinoma with enteroblastic differentiation. A 75-year-old woman was admitted to our hospital with occasional upper abdominal discomfort. We performed gastroscopy and observed a type 2 tumor, primarily in the pyloric region. Histological examination of biopsies confirmed gastric adenocarcinoma. Based on these findings, we d...

Pneumolysin, a multifunctional toxin produced by all clinical isolates of Streptococcus pneumoniae, is strongly implicated in the pathogenesis of pneumococcal bronchopneumonia and septicemia. Using isogenic mutant strains, we examined the effect of deletion of the cytotoxic activity or complement-activating activity of pneumolysin on bacterial growth in lungs and blood, histological changes in ...

OBJECTIVE To correlate the different non masslike enhancement categories detected by Magnetic Resonance Imaging (MRI) and the corresponding histological findings. PATIENTS AND METHODS Two experienced radiologists reviewed the MRI examinations of 94 patients presenting non mass-like enhancements who had performed histological evaluation. According to the BI-RADS (Breast Imaging Reporting and D...

AIMS To evaluate the impact of a histologically inverted pattern on recurrence in patients with newly diagnosed non-invasive, low-grade papillary urothelial carcinoma of the urinary bladder. METHODS A total of 81 patients with primary bladder non-invasive, low-grade papillary urothelial carcinoma diagnosed in a single tertiary-care centre who had at least 1-year follow-up after an initial res...

Placodontia is a clade of durophagous, near shore marine reptiles from Triassic sediments of modern-day Europe, Middle East and China. Although much is known about their primary anatomy and palaeoecology, relatively little has been published regarding their life history, i.e. ageing, maturation and growth. Here, growth records derived from long bone histological data of placodont individuals ar...
