Objective: This study was designed to evaluate prospectively survival after pancreaticoduodenect-omy for pancreatic adenocarcinoma, comparing two different postoperative adjuvant chemoradiation protocols to those of no adjuvant therapy. Summary Background Data: Based on limited data from the Gastrointestinal Tumor Study Group. Adjuvant chemoradiation therapy has been recommended after pancreati...

Nerve sheath myxomas (NEUROTHEKEOMA) are uncommon tumors of nerve sheet origin. These tumors most frequently arise from in the dermis and subcutaneous tissues of the head and neck, and upper extremities. Neurothekeoma may be either asymptomatic or may present as a painful raised, skin colored, well circumscribed dermal lesion averaging 1 cm in diameter. This entity is especially rare in the foo...

Atomic rearrangements leading to the coalescence of fullerene cages are revealed by topological analysis. Paths found for nanotubes and C(60) consist exclusively of Stone-Wales bond rotations. Computed intermediate states show gradual evolution from separate clusters to completely fused coherent units. Molecular dynamics simulations follow the predicted routes, overcome the nucleation barrier, ...

Branch pipe T-joints are used to connect and bifurcate hydraulic channels in big power plants size. These components submitted enormous strengths that must be counteracted by integrated structures the T-joint, for this case specified arrangement type "Nun neck". The main objective work is about validate structurally numerical analysis branch T-joint design with reinforcement “Nun Neck” operatio...

What are they? Dendritic spines are small protrusions that emerge from the dendrites of neurons (Figure 1). Most excitatory synapses in the brain are found on spine heads. Typically, a spine consists of a bulbous head, volume 0.001–1 μm3, at the end of a thin spine neck, diameter around 0.1 μm. A 100 μm length dendrite can contain several hundred spines. The human cerebral cortex is thought to ...

Introduction: The human anthropometric characteristics are surveyed in anthropology. Anthropology is used in archeology, rehabilitation and legal medicine. The purpose of this study was to determine femur which has a special place in the science of anthropometry. Methods: To measure the femur, both direct and indirect methods was used. The direct method of measuring the 113 femur in dissection...

Lower left, Detail of a skin ulcer on forehead of patient. Lower right, Histologic examination of skin biopsy specimen showing perivascular infiltrates of neutrophil granulocytes and ovoid yeasts (diameter, 15 mm) and a thick cell wall (peri...

We describe a case of an 81-year-old patient, where we used a new technique for the reconstruction of postauricular defects (of 3 x 4 cm diameter). The swallowtail flap is an advancement flap that allows getting beyond the repair of the defect, providing an excellent aesthetic result because the scar is masked in the neck and retroauricular folds and does not alter the shape and projection of t...

Forty female Angora goats were selected at random from the experimental nucleus of the National Institute of Agricultural Technology (Pilcaniyeu, Argentina), with the aim of analyzing the variability of main fleece characteristics of the Angora goats and establishing an optimum sampling site. Samples were taken at the first and second shearings (12 and 18 months of age) from the following parts...

abstract in order to study the effects of irrigation regimes and plant spacing on bulb yield of two onion (allium cepa l.) genotypes, an experiment was conducted at kabootar abad research station of isfahan during two growing seasons (2005 and 2006). the experiment design was split-factorial with a randomized complete block arrangement with four replications. main plots included three irrigatio...
