Neuroblastoma-like schwannoma is known as a rare unusual variant of with difficulties differential diagnosis neuroblastoma, Ewing sarcoma/peripheral neuroectodermal tumor and other cutaneous small round cell tumors. Herein, we describe neuroblastoma-like that was presented painless lesion on the dorsal side left hand in 39-year-old woman. Composed collagen fibers central core rosettes diffuse e...

Abstract In our research work, we analyzed the mechanical properties of 3D-printed metallic specimens aluminium bronze material. evaluation, had five groups specimens, manufactured at different laser scanning speeds. total, 25 for which examined various parameters like ultimate tensile strength, engineering yield point, relative strain, and hardness. Results showed that prepared with a lower sp...

in this paper attempts have been done to create a mortar with relatively high uniaxial compressive strength (ucs), easy casting, high flexibility, instant hardening, low cost and easy availability. the main use of this material is to physically model the mechanical behavior of jointed rock-like blocks. the effect of four parameters such as joint roughness coefficient (jrc), bridge length (l), b...

Reverse transcription-PCR and sequence analysis identified calciviruses in 32 of 60 stool specimens (negative for other enteric pathogens) obtained from children admitted to our hospital with acute gastroenteritis. The overall annual incidence rate for calcivirus was 9% (32 of 354 children). Molecular analysis identified 30 "Norwalk-like virus" genogroup II (predominantly Lordsdale cluster) and...

Deformation-induced martensitic transformation as the basis of a hardening process is dependent, among others, on stress state. In applications such cryogenic cutting, where hardened subsurface can be produced in metastable austenitic steels, different states exist. Furthermore, cutting typically occurs at high strain rates greater than 103s?1. order to gain deeper insight into behavior steel (...

INTRODUCTION Knowledge about the current status of the epidermal growth factor receptor (EGFR) has resulted in an improvement in the treatment of non-small cell lung cancer. In contrast, small cell lung cancer (SCLC) continues to frustrate clinicians with its tendency toward early metastasis and chemotherapy resistance. Recent studies have reported the EGFR mutation and its response to gefitini...

Background: Gallstone disease called as cholelithiasis is the most common digestive surgical disorder and account for an important part of health care expenditure. Aim: This work was carried out to study the diverse histopathological changes in the gallbladder mucosa as a result of cholelithiasis. Materials and Methods: This was a retrospective study carried out in the Department of Pathology, ...

two polygonal biogenic sedimentary rare structures of koilosoma (hitchcock 1858) have been found due to neoichnology of the abhar-rud river fluvial sediments, northwest iran. one of them is polygon holes, with about one square meter area. polygons are same in size and depth, and are hexagonal in shape. they have distinct boundaries like the honeycomb. this sample is like the reported specimens ...

Heterogeneous lamella (HL) structures were produced via simple processing steps in a FeCoNi-based complex concentrated alloy (CCA) with superalloy-like FCC/L12 microstructure. Compared to the homogeneous-structured control specimens, HL-structured specimens exhibited synergic enhancements strengths and ductility (with σy up 1 GPa, σu 1.4 ϵt 16.5%), at same time, higher saturation magnetization ...
