Though manufacturing spheroidal graphite cast irons is a well-established industrial process, good nodularity which essential for mechanical properties may be hampered by several factors. Amongst them the presence of impurities at trace level lead to growth protrusions and question how they can destroy spheroidizing effect magnesium. For first time, it shown that such are present together with ...

Rheumatoid arthritis is not a rare condition in east Iran. We have compiled a study of 76 patients with classic and definite RA in the Rheumatology Department of Ghaem Medical School in east Iran. All patients were admitted for clinical and serological evaluation. In terms of sex ratio, pattern of joint involvement, severity and nodularity, RA in east Iran did not resemble that which has b...

BACKGROUND/AIMS Gastric dysplasia is generally accepted to be the precursor lesion of gastric carcinoma. Approximately 25% to 35% of histological diagnoses based on endoscopic forcep biopsies for gastric dysplastic lesions change following endoscopic resection (ER). The aim of this study was to determine the predictive endoscopic features of high-grade gastric dysplasia (HGD) or early gastric c...

OBJECTIVE To evaluate the efficacy and safety of omeprazole-based dual and triple regimens for the treatment of children with Helicobacter pylori infection. METHODS Twenty-two patients (3 with gastric ulcer, 12 with duodenal ulcer, and 7 with nodular gastritis alone) were studied. Twelve ulcer patients also had nodular gastritis. The dual regimen included a 2-week course of omeprazole (0.6 mg...

: Medulloblastoma with extensive nodularity (MBEN) is a rare histological subtype of medulloblastomas in very young children. It characterized by an aggressive grape-like appearance and favorable outcomes. Herein, we report the case nine-month-old patient MBEN, associated activated sonic hedgehog (SHH), multimodal magnetic resonance imaging (MRI) features. Conventional MRI findings indicated de...

OBJECTIVE Atypical teratoid rhabdoid tumor is a rare neoplasm with a distinct cytogenetic profile that predominates in infancy. Many cases show predominance of small cells with scanty rhabdoid cells, making recognition of this tumor difficult. We aim at describing our experience with atypical teratoid rhabdoid tumor cases diagnosed over a 6-year period. MATERIAL AND METHOD Clinicopathologic f...

We report a case of cerebellar neuroblastoma in a 19-week-old p53 null mutation mouse. A white and soft mass was observed at the cerebellar vermis. Histologically, the tumor consisted of solid growth of round to oval pleomorphic cells with frequent mitotic figures. While there were no typical cellular arrangements of embryonic neurogenic tumors, such as Homer-Wright rosette, perivascular pseudo...

Eksperimen ini bertujuan untuk menginvestigasi perubahan sifat mekanik dan struktur mikro besi cor nodular setelah dilakukan tempering pada temperatur 350 °C 450 dengan waktu penahanan selama satu jam dilanjutkan pendinginan udara. Sebelum terlebih dahulu perlakuan panas hardening 850 quenching media oli. Besi yang digunakan penelitian memiliki kandungan 3,45% C, 2,6% Si, 0,635% Mn, 1,58% Ni, 0...
