Rhabdomyosarcoma (RMS) is the most common malignant tumor of the orbit in children, but it is rarely present at birth. We report a large congenital orbital RMS with intracranial extension in a newborn baby. A newborn baby girl was referred to our hospital due to severe right-eye exophthalmia. Imaging studies showed an orbital mass with intracranial extension. Treatment was started with a course of neoadjuvant chemotherapy followed by right orbital exenteration and intracranial resection of the tumor. Histologic examination of the mass showed undifferentiated malignant small-cell tumor...

Propranolol (Pro), a non-specific β-adrenergic blocking drug, competitively prevents the binding of catecholamines to receptors and suppresses cancer cells. The anti-tumor activity of propranolol has been proved in different kinds of cancers. In this study, we assessed the adjuvant activity of propranolol combined with a tumor vaccine model on the immunological parameters of breast tumor-bearing mice. Breast tumor pieces were implanted into the flank of inbred BALB/C female mice from stock mice. Tumor-bearing mice were treated with tumor antigen lysate vaccine and propranolol/Vaccine (Pro/Vac) combination (as treatment groups), propranolol and PBS (as control groups) for 5 consecutive days, every 12 h...

OBJECTIVE: In vacuum wound therapy (VAC) a negative pressure can continuously clean effusions and enhance the formation of granulation tissue significantly. In visceral, trauma and burns surgery this technique is used frequently in critical wounds. In the head and neck area there is limited experience and publications. Especially in the combined use of split-thickness-skin grafts (STSG) and VAC there is no published evidence. MATERIAL AND METHODS: A retrospective database analysis was done and resulted in 36 single VAC therapies in 13 patients...

BACKGROUND: Bilirubin may protect against cardiovascular disease (CVD) by reducing oxidative stress. Whether elevated bilirubin reduces the risk of CVD events among HIV+ individuals and if this differs from uninfected individuals remain unclear. We assessed whether bilirubin independently predicted the risk of CVD events among HIV+ and uninfected participants in VACS (Veterans Aging Cohort Study). METHODS AND RESULTS: We conducted a prospective cohort study using VACS participants free of baseline CVD...

A new, sensitive and simple method based on vacuum-assisted headspace solid-phase microextraction (Vac-HSSPME) followed by gas chromatography-mass-spectrometry (GC-MS), is proposed for the quantification of rocket fuel unsymmetrical dimethylhydrazine (UDMH) transformation products in water samples. The target transformation products were: pyrazine, 1-methyl-1H-pyrazole, N-nitrosodimethylamine, N,N-dimethylformamide, 1-methyl-1Н-1,2,4-triazole, 1-methyl-imidazole and 1H-pyrazole. For these analytes and within shorter sampling times, Vac-HSSPME yielded detection limits (0...

BACKGROUND: Duck enteritis virus (DEV) belongs to the family Herpesviridae and is an important epornitic agent that causes economic losses in the waterfowl industry. The Chinese virulent (CHv) and attenuate vaccines (VAC) are two different pathogenic DEV strains. MicroRNAs (miRNAs) are a class of non-coding RNAs that regulate gene expression in viral infection. Nonetheless, there is little information on virulent duck enteritis virus (DEV)-encoded miRNAs. RESULTS: Using high-throughput sequencing, we identified 39 mature viral miRNAs from CHv-infected duck embryo fibroblasts cells...

Recent methods for the analysis of molecular kinetics from massive molecular dynamics (MD) data rely on the solution of very large eigenvalue problems. Here we build upon recent results from the field of compressed sensing and develop the spectral oASIS method, a highly efficient approach to approximate the leading eigenvalues and eigenvectors of large generalized eigenvalue problems without ever having to evaluate the full matrices. The approach is demonstrated to reduce the dimensionality of the problem by one or two orders of magnitude, directly leading to corresponding savings in the computation and storage of the necessary matrices, and a speedup of two to four orders of magnitude in solving the eigenvalue problem...

A 24-year-old woman was admitted to the hospital for abdominal pain. Abdominal contrast-enhanced computed tomography( CT)revealed a cystic mass measuring 11×8 cm in the left lobe of the liver with extravasation. Vascular embolization was performed, but extravasation remained on CT images. She was then transferred to our hospital. We performed an emergency extended left hepatectomy. Histopathological examination revealed solid proliferation of spindle-shaped cells. Immunohistochemical staining showed that the tumor cells were positive for vimentin and negative for AE1/AE3...

Enhancing the performance of wood adhesive is important for its industrial applications. Accordingly, we designed and demonstrated the use of two co-monomers vinyl acetate (VAc) and butyl acrylate (BA) for promoting the graft copolymerization while improving the bonding performance of wood adhesive. The results showed that the addition of co-monomers in the ratio of VAc/BA 6:4 (v/v, volume basis of VAc) could improve the shear strength to 6.68 MPa and 3.32 MPa in dry and wet states, respectively.1 H-nuclear magnetic resonance (1 H NMR) and fourier transform infrared spectroscopy (FT-IR) analysis revealed successful graft copolymerization reaction while the morphologies were observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM)...

Enteroatmospheric fistulas (EAF) are rare but challenging and morbid complications of abdominal surgery and require time- as well as resource-consuming management. Furthermore, they severely affect patients' quality of life. Several treatment modalities for EAF management are described in the literature. We describe 3 consecutive cases of EAF treatment by employing negative pressure wound therapy (NPWT) along with either a special silicone fistula adapter or a Silo-Vac-like system in another case to isolate the fistula from the remaining abdominal wound...
