The pyriform silk of the attachment disc a spider was studied using infrared-visible vibrational sum frequency generation (SFG) spectroscopy. can attach dragline and radial lines to many kinds substrates in nature (concrete, alloy, metal, glass, plant branches, leaves, etc.) with disc. adhesion bear spider's own weight, resist wind on its orb web. From our SFG spectroscopy study, NH group argin...

OBJECTIVE The purpose of this study was to compare clinical and radiological outcomes of percutaneous endoscopic lumbar discectomy (PELD) and open lumbar microdiscectomy (OLM) for recurrent disc herniation. METHODS Fifty-four patients, who underwent surgery, either PELD (25 patients) or repeated OLM (29 patients), due to recurrent disc herniation at L4-5 level, were divided into two groups ac...

BACKGROUND Gastrointestinal stromal tumors (GIST) are infrequent and diagnosis and prognosis could be troublesome. We present short and long term results of surgical resection for GIST at the Department of Surgery, University of Insubria, during a period of 17 years. MATERIALS AND METHODS All patients' data, tumor characteristics, surgical procedure and survival data were analyzed retrospecti...

abstract soil invertebrate and their spatial pattern are affected strongly by environmental factors. spatial variability of soil properties is one of the most important reasons of the macrofauna variability. this study was conducted to investigate the spatial variability of soil properties and soil macrofauna biomass in the riparian forest landscape of karkhe river. soil macro fauna were sample...

A 25-year old man presented with chronic low back pain for about 5 years due to mild congenital lumbar kyphosis (L1-L3 25° with congenital posterior wedge vertebra L2). Preoperative neurologic examination was normal. After posterior spinal fusion and instrumentation with moderate curve correction, the patient gradually developed the symptoms and signs of cauda equina syndrome due to intraoperat...

In this study, polyacrylamide disc gel electrophoresis and densitometry analysis methods were used to analyze venom extracts of Vipera xanthina specimens of different lengths (35, 47 and 88 cm) collected from the same locality. The electropherograms of the venom protein samples showed age-dependent qualitative and quantitative variations.

ABSTRACT We investigate the dynamic evolution of gaseous regions around FS CMa post-mergers. Owing to slow rotation central B-type star, dynamics is driven mainly by magnetic field star. Recent observations have allowed us set realistic initial conditions, such as value ($B_\star \approx 6\times 10^{3}\, \mathrm{G}$), mass star ($M_\star =6\, \mathrm{M}_\odot$), and disc density $\rho _{d0}\in ...
