The stability and catalytic activity of W@Pt core-shell structure.

This paper reports a study of the electronic properties, structural stability and catalytic activity of the W@Pt core-shell structure using the First-principles calculations. The degree of corrosion of W@Pt core-shell structure is simulated in acid solutions and through molecular absorption. The absorption energy of OH for this structure is lower than that for Pt, which inhibits the poison effect of O containing intermediate.

A spinal tumor showing mixed features of ependymoma and hemangioblastoma: a case report and literature review.

We report an intramedullary spinal tumor consisting of an ependymoma and a hemangioblastoma (HB). A 37-year-old woman presented with progressive bilateral lower limb sensory and motor deficits. Magnetic resonance imaging showed a single intramedullary mass in the thoracic cord (T4-T6 level).

Papillary meningioma: clinical and histopathological observations.

Papillary meningioma is a rare subtype of malignant meningiomas, which is classified by the World Health Organization as Grade III. Because of lack of large sample size case studies, many of the specific characteristics of papillary meningioma are unclear. This study investigated by retrospective analysis the clinical, radiological and histopathological findings of 17 papillary meningioma patients who underwent surgical resection or biopsy, to assess the characteristics of papillary meningioma.

Histopathological classification and location of consecutively operated meningiomas at a single institution in China from 2001 to 2010.

Background: Meningioma is one of the most common primary tumors of the central nervous system, but there are not many detailed studies on the sex, age, subtypes and locations of large series. This study was a retrospective analysis of the characteristics of meningioma cases consecutively operated on at a single institution in China from 2001 to 2010.

Methods: This study investigated the demographic background of 7084 meningioma cases, and the subtypes and locations of the tumors.

Secretory meningiomas: clinical, radiological and pathological findings in 70 consecutive cases at one institution.

Secretory meningioma (SM) is a rare, benign subtype of meningioma. Between January 2005 and December 2010, 70 SMs were operated on at the Department of Neurosurgery, Huashan Hospital, Fudan University. We retrospectively analyzed the clinical data, radiological and immunohistochemical findings, and patient outcome to discuss the specific features of SMs.

Effect of chronic pretreatment of angiotensin-converting receptor blocker on no-reflow phenomenon in patients with acute myocardial infarction undergoing percutaneous coronary intervention.

Aims: Angiotensin receptor blockers (ARBs) exert favorable effects on the vascular system, which are not directly related to hypertension lowering function. The no-reflow phenomenon determines the prognosis in patients after acute myocardial infarction (AMI). Early ARB treatment has many beneficial effects on the prognosis after AMI.

Embryonal tumor with abundant neuropil and true rosettes (ETANTR) with a focal amplification at chromosome 19q13.42 locus: further evidence of two new instances in China.

Recently, the term "embryonal tumor with multilayered rosettes" (ETMR), including embryonal tumor with abundant neuropil and true rosettes (ETANTR) and ependymoblastoma (EBL) as a distinct tumor entity, has become an important topic of discussion for neuropathologists since the discovery of a unique genomic alteration in 2009. Here, we contribute two new East Asian instances of ETANTR in a 29-month-old boy who underwent subtotal resection of a large tumor in the bilateral parieto-occipital lobes and a 4-year-old boy who underwent subtotal resection of the right midpontine neoplasm. Both tumors showed a typical histopathological pattern of hypercellular clusters of undifferentiated small cells and ependymoblastic rosettes admixed with paucicellular neuropil-like zones indicative for ETANTR.

Rosette-forming glioneuronal tumor: report of an unusual case with intraventricular dissemination.

A rosette-forming glioneuronal tumor (RGNT) was encountered in a 16-year-old Chinese girl. She experienced seizures with loss of consciousness for 1 month prior to diagnosis. A brain MRI revealed multifocal masses occupying all of the ventricular system associated with marked hydrocephalus.

Messenger RNA expression of translationally controlled tumor protein (TCTP) in liver regeneration and cancer.

Objective: Translationally controlled tumor protein (TCTP) was recently reported to be involved in tumor reversion. In order to understand TCTP mRNA transcript in proliferative tissue and malignant lesions, the mRNA expression of TCTP was determined in a rat model of liver regeneration and human liver cancer tissues. In addition, the potential role of TCTP on suppression of liver cancer was investigated.
