Introduction: Diagnosis of neurofibroma usually is based on the specific morphology and arrangement of mesenchymal cells in routine Hematoxylin and Eosin (H&E) sections, and detection of mast cells supports the diagnosis. Sometimes definite diagnosis from other mesenchymal lesions may be difficult. The aim of the present study was to compare S100 expression and mast cells count (as Gold Standar...

OBJECTIVE We aimed to review our archives in order to evaluate both the diagnostic and prognostic significance of DOG1 on gastrointestinal stromal tumors (GISTs), and add further insight about those issues to the current literature including some conflicting results. MATERIAL AND METHOD DOG1 was evaluated in 100 cases of GISTs, immunohistochemically. Immunostaining index was counted for each ...

PURPOSE The major drawback of the current treatment for superficial bladder tumor is the high rate of recurrence. Especially, the tumor with grade 3 component has a tendency to recur and progress in stage. However, we have difficulty in predicting tumor recurrence and stage progression accurately by conventional clinicopathological factors. We evaluated the efficacy of p53 and Ki-67 overexpress...

the mathematical properties of nano molecules are an interesting branch of nanoscience forresearches nowadays. the periodic open single wall tubulene is one of the nano moleculeswhich is built up from two caps and a distancing nanotube/neck. we discuss how toautomatically construct the graph of this molecule and plot the graph by spring layoutalgorithm in graphviz and netwrokx packages. the sim...

The epidemiology of measles has been investigated in Niakhar, a rural area of Senegal, during two periods, 1983-1986 and 1987-1990. Following a major increase in immunization coverage beginning in 1987, the case fatality ratio for all ages declined fourfold from the first to the second period (relative risk (RR) = 0.24, 95% confidence interval (CI) 0.13-0.46). The measles incidence for children...

BACKGROUND Little is known about how human immunodeficiency virus (HIV) infection affects influenza transmission within homes in sub-Saharan Africa. METHODS We used respiratory illness surveillance and HIV testing data gathered in Kibera, an urban slum in Nairobi, Kenya, to examine the impact of HIV status on (1) introducing influenza to the home and (2) transmitting influenza to household co...

Relatives of postmenopausal breast cancer patients have a greater risk of breast cancer than do women with no family history of the disease. However, no study has previously examined the contribution of other breast cancer risk factors to risk in these relatives, thus precluding the ability to discern between shared environment or genes as the cause of familial aggregation. We conducted a neste...

The albumin globulin ratio (A/G ratio) is meant to represent the ratio of alterations in serum proteins, since, in liver disease, globulins (G) rise following serum albumin (SA) decrease. pathophysiological value, its' use has been limited. Alternatively, we have developed an index, the globulin compensation index (GCI) to measure the changes in serum globulins when albumin is decreased. The in...

BACKGROUND There is little knowledge about familial hypercholesterolemia in Brazil. This study presents the first results of genetic cascade screening performed in the city of Sao Paulo. MATERIAL AND METHODS Two-hundred and forty-eight suspected index cases were initially included. DNA was extracted from peripheral blood and the complete coding sequence of low-density lipoprotein receptor, ex...

BACKGROUND DNA fingerprinting of Mycobacterium tuberculosis isolates offers better opportunities to study links between tuberculosis (TB) cases and can highlight relevant issues in urban TB control in low-endemic countries. METHODS A medium-sized molecular cluster of TB cases with identical DNA fingerprints was used for the development of a visual presentation of epidemiologic links between c...
