Hemangiopericytomas are soft tissue tumors composed of pericytic cells that are characterized by their "staghorn" vascular branching and their variable clinical presentation. Fifteen to 25% of all HPC occur in the head and neck, with only 5% found in the nose or paranasal sinuses. Sinonasal hemangiopericytoma (SNHPC) is considered distinct from its soft tissue counterpart - the former showing a more uniform cellular organization, has convincing pericytic differentiation and is associated with a far better prognosis...

Student perceptions of self-efficacy (SE) prevent stress and burnout and improve engagement in nursing education, thus increasing learning outcomes. The study aims were to (1) validate a scale measuring nursing SE in psychomotor skills (NSE-PS), (2) describe changes in NSE-PS over time, and (3) explore NSE-PS correlations with burnout and engagement. A total of 1117 nursing students participated. A significant increase in the NSE-PS scores over the years has emerged; in addition, all NSE-PS dimensions were correlated negatively with burnout and positively with engagement...

Purpose: The objective of this study was to develop, characterize, and comparatively investigate the ketotifen fumarate (KF) nanosuspensions (NSS) to enhance the permeability of KF. Methods: In the present work, the NSP and NSE were prepared by double-emulsion solvent evaporation/nanoprecipitation methods with poly (D,Llactide-co-glycolide) and Eudragit RL100 polymers, respectively. The loading efficiency, particle size, and polydispersity index of prepared different NSs were evaluated with scanning electron microscopy (SEM), X-ray diffraction, differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR), and in vitro release and transcorneal permeation ...

BACKGROUND: Sarcomatoid urothelial carcinoma (SUC) is a rare malignant neoplasm of the urinary bladder comprising 0.2-0.6 % of all histological bladder tumor subtypes. It presents as a high-stage malignancy and exhibits aggressive biological behavior, regardless of the treatment employed. It is defined as histologically indistinguishable from sarcoma and as a high-grade biphasic neoplasm with malignant epithelial and mesenchymal components. The mean age of patients presenting with SUC is 66 years, and the male-to-female ratio is 3:1...

BACKGROUND: The aim of our current investigation was to analyze the autoantibody -reactivities of patients after acute angle closure glaucoma (AACG) by means of a protein microarray approach to identify intraocular pressure (IOP)-dependent antibodies. METHODS: Collected sera from different study time points (AACG n = 6, 0, 2, 4 and 12 weeks) and control group (CTRL n = 11, 0 and 12 weeks) were analyzed. Protein-microarrays were incubated with sera and occurring immunoreactivities were visualized with fluorescence labeled anti-human-IgG antibodies...

OBJECTIVE: To study the relationship between the levels of erythropoietin (EPO) in serum and brain injury in preterm infants. METHODS: Three hundred and four preterm infants (gestational age: 28-34 weeks) born between October 2014 and September 2015 were enrolled in this study. Brain injury was diagnosed using cerebral ultrasound and MRI. The levels of EPO, S100 protein, neuron-specific enolase (NSE) and myelin basic protein (MBP) in serum were detected using ELISA...

The chain and association dynamics of supramolecular polymer ensembles decisively determines their properties. Using neutron spin echo (NSE) spectroscopy we present molecular insight into the space and time evolution of this dynamics. Studying a well characterized ensemble of linearly associating telechelic poly(ethylene glycol) melts carrying triple H-bonding end groups, we show that H-bond breaking significantly impacts the mode spectrum of the associates. The breaking affects the mode contributions and not the relaxation times as was assumed previously...

Fully developed homogeneous isotropic turbulence in two dimensions is fundamentally different from that in three dimensions. In two dimensions, the simultaneous inviscid conservation of both kinetic energy and enstrophy within the inertial range of scales leads to a forward cascade of enstrophy and a reverse cascade of energy. In three dimensions, helicity, the integral of the scalar product of velocity and vorticity, is also an inviscid flow invariant along with the energy. Unlike the enstrophy, however, the helicity does not block the forward cascade of energy to small scales...

BACKGROUND: Alcohol-induced neurodegeneration, a consequence of chronic ethanol exposure, is a neuroadaptation that drives the progression of alcohol use disorder (AUD). Unfortunately, conventional drugs for AUDs do not prevent neurodegeneration as part of their pharmacological repertoire. Multimodal neuroprotective therapeutic agents are hypothesized to have high therapeutic utility in the treatment of central nervous system. Interestingly, nutraceuticals by nature are multimodal in mechanisms of action...

OBJECTIVE: To investigate the clinical efficacy of serum carcinoembryonic antigen (CEA) and neuron-specific enolase (NSE) as biomarkers for diagnosis of nonsmall cell lung cancer (NSCLC). MATERIAL AND METHODS: Forty-six cytology or pathology confirmed nonsmall cell lung patients and 33 cases of benign lung disease (BLD) were retrospective reviewed in our hospital from February 2013 to January 2016. The serum concentrations of CEA and NSE were measured by chemiluminescent assay...

Our objective is to study the relationship between the regulatory proteins Bcl-2/Bax and mitochondria-mediated apoptosis during the differentiation of adipose-derived stromal cells (ADSCs) into neurons. Immunocytochemistry and western blotting showed that the cells weakly expressed neuron-specific enolase (NSE) in the non-induced group and expressed NSE more strongly in the groups induced for 1 h, 3 h, 5 h and 8 h. NSE expression peaked at 5 h (P < 0.05), although there was no significant difference between 5 and 8 h (P > 0...

The 70 kDa heat shock protein (Hsp70) is a highly conservative molecular chaperone, that has important role in cell integrity. Recently considerable amount of data are accumulating on the potential role of Hsp70 in carcinogenesis and tumor progression. Most papers are focusing on intracellular or membrane bound protein, however very limited data exist on serum Hsp70, that can also induce innate and adaptive immune response. Previously we have published data on the correlation between coloretal cancer progression and serum Hsp70 concentration...

INTRODUCTION: Primitive neuroectodermal tumor (PNET)/Ewing's sarcoma (EWS) belongs to a family of neoplasms that are presumed to originate from the neuroectodermal crest. PNET/EWSs are highly aggressive malignancies that usually present in the form of bone or soft tissue masses and usually affect adolescents and young adults. Primary PNET/EWS of the kidney is very rare. CASE PRESENTATION: We present the case of a 32-year-old female patient with primary renal PNET/EWS diagnosed nine years and eight months earlier...

AIM: This study evaluated the curative potential of Crinum giganteum in the treatment of schizophrenia using an NMDA-receptor antagonist-induced schizophrenic Wistar rat model. METHODS: Twenty-five adult Wistar rats of both sexes of average weights 180 g were divided into two groups: control and schizophrenic rat models. The controls received 0.1 ml of 0. 9% saline, while schizophrenia was induced in models using 25 mg/kg of ketamine hydrochloride (i.p.) for 7 days...

An ~21-year-old female Barbary sheep (Ammotragus lervia) died spontaneously following a lengthy episode of difficulty in walking. An ~6 × 3 × 3 cm, unilocular cystic growth was found in the cranioventral thorax. The fibrotic cystic wall, lined by a single layer of flattened to cuboidal epithelial cells, was invaginated and partially encircled solid masses of fusiform neoplastic cells with multiple intratumoral cystic structures. The fusiform neoplastic cells were intensely positive for cytokeratin (CK) and partially positive for α-smooth muscle actin and vimentin, but negative for thyroid transcription factor-1 (TTF-1) and neuron-specific enolase (NSE)...

BACKGROUND: Neuroendocrine markers, which could indicate for aggressive variants of prostate cancer and Ki67 (a well-known marker in oncology for defining tumor proliferation), have already been associated with clinical outcome in prostate cancer. The aim of this study was to investigate the prognostic value of those markers in primary prostate cancer patients. PATIENTS AND METHODS: NSE (neuron specific enolase), ChrA (chromogranin A), Syp (Synaptophysin) and Ki67 staining were performed by immunohistochemistry...
