Abstract
Using electron correlograph analysis we show that coherent nanodiffraction patterns from sputtered amorphous silicon indicate that there is more local crystallinity in unannealed amorphous silicon than was previously suspected. By comparing with simulations for various models we show that within a typical unannealed amorphous silicon film a substantial volume fraction (>50%) is topologically crystalline with correlation lengths up to 2 nm. Electron correlograph analysis is a variant of the fluctuation electron microscopy technique and its sensitivity to local crystalline ordering is derived from its sensitivity to four-body correlations.

Abstract
Hookworm infection is associated with anaemia and malnutrition in many resource-limited countries. Ancylostoma hookworms have previously been shown to modulate host cellular immune responses through multiple mechanisms, including reduced mitogen-mediated lymphocyte proliferation, impaired antigen presentation/processing, and relative reductions in CD4(+) T cells in the spleen and mesenteric lymph nodes. Syrian hamsters were depleted of CD4(+) for up to 9 days following intraperitoneal injection (200 microg) of a murine anti-mouse CD4 monoclonal IgG (clone GK1.5). CD4(+) T-cell-depleted hamsters infected with the hookworm Ancylostoma ceylanicum exhibited a threefold higher mean intestinal worm burden and more severe anaemia than animals that received isotype control IgG. In addition, depletion of CD4(+) T cells was associated with impaired cellular and humoral (serum and mucosal) immune responses to hookworm antigens. These data demonstrate an effector role for CD4(+) T cells in hookworm immunity and disease pathogenesis. Ultimately, these studies may yield important insights into the relationship between intestinal nematode infections and diseases that are associated with CD4(+) T-cell depletion, including HIV.

Abstract
STUDY DESIGN A retrospective study. OBJECTIVES To study the outcome of repair of cauda equina fibres with fibrin glue after lumbar fracture and/or dislocation. METHODS Seven acute cases and one chronic case of L2 or L3 fracture and/or dislocation complicated with complete cauda equina injury were selected. Sural nerve or ventral roots of injured cauda equina were chosen to repair the motor cauda equina fibres with fibrin glue after open reduction and internal fixation of the unstable vertebrae. The functional recovery after surgery was observed. RESULTS Recovery of the strength of thigh muscles (iliopsoas, quadriceps femoris, gluteus maximus, adductors) was observed in all seven acutely injured patients (t=3.74, P<0.05), but not in the chronic one. Neither recovery of leg muscles nor sensation of the lower extremities was observed in any case. CONCLUSIONS The cauda equina ventral roots injured after lumbar fracture and/or dislocation can be repaired with fibrin glue and motor recovery is expected.

Abstract
The cloning of alpha-amylase gene of S. occidentalis and the construction of starch digestible strain of yeast, S. cerevisiae AS. 2. 1364 with ethanol-tolerance and without auxotrophic markers used in fermentation industry were studied. The yeast/E. coli shuttle plasmid YCEp1 partial library of S. occidentalis DNA was constructed and alpha-amylase gene was screened in S.cerevisiae by amylolytic activity. Several transformants with amylolysis were obtained and one of the fusion plasmids had an about 5.0 kb inserted DNA fragment, containing the upstream and downstream sequences of alpha-amylase gene fromS. occidentalis. It was further confirmed by PCR and sequence determination that this 5.0 kb DNA fragment contains the whole coding sequence of alpha-amylase. The amylolytic test showed that when this transformant was incubated on plate of YPDS medium containing 1% glucose and 1% starch at 30 degrees Celsius for 48 h starch degradation zones could be visualized by staining with iodine vapour. alpha-amylase activity of the culture filtratate is 740-780 mU/mL and PAGE shows that the yeast harboring fusion plasmids efficiently secreted alpha-amylase into the medium, and the amount of the recombinant alpha-amylase is more than 12% of the total proteins in the culture filtrate. These results showed that alpha-amylase gene can be highly expressed and efficiently secreted inS. cerevisiae AS. 2.1364, and the promotor and the terminator of alpha-amylase gene fromS. occidentalis work well inS. cerevisiae AS. 2.1364.

Abstract
Fiber Bragg gratings with greatly enhanced thermal stability have been fabricated by the use of femtosecond laser pulse irradiation on optical fibers with relaxed residual stress, through using high temperature annealing treatment. The grating reflectivity and resonant wavelength can be maintained for periods up to 20 hours using isothermal measurements and temperatures up to 1200 degrees C. No hysteresis was observed in the wavelength response when the gratings were annealed and the temperature cycled repeatedly between room temperature and 1200 degrees C.

Abstract
Schottky junction photovoltaic (PV) devices were fabricated on single CdS nanobelts (NBs). Au was used as the Schottky contact, and In/Au was used as the ohmic contact to CdS NB. Typically, the Schottky junction exhibits a well-defined rectifying behavior in the dark with a rectification ratio greater than 10(3) at +/- 0.3 V; and the PV device exhibits a clear PV behavior with an open circuit photovoltage of about 0.16 V, a short circuit current of about 23.8 pA, a maximum output power of about 1.6 pW, and a fill factor of 42%. Moreover, the output power can be multiplied by connecting two or more of the Schottky junction PV devices, made on a single CdS NB, in parallel or in series. This study demonstrates that the 1D Schottky junction PV devices, which have the merits of low cost, easy fabrication and material universality, can be an important candidate for power sources in nano-optoelectronic systems.

Abstract
Analysis of in vitro cell motility is a useful tool for assessing cellular response to a range of factors. However, the majority of cell-tracking systems available are designed primarily for use with fluorescently labelled images. In this paper, five commonly used tracking systems are examined for their performance compared with the use of a novel in-house cell-tracking system based on the principles of image registration and optical flow. Image registration is a tool commonly used in medical imaging to correct for the effects of patient motion during imaging procedures and works well on low-contrast images, such as those found in bright-field and phase-contrast microscopy. The five cell-tracking systems examined were Retrac, a manual tracking system used as the gold standard; CellTrack, a recently released freely downloadable software system that uses a combination of tracking methods; ImageJ, which is a freely available piece of software with a plug-in for automated tracking (MTrack2) and Imaris and Volocity, both commercially available automated tracking systems. All systems were used to track migration of human epithelial cells over ten frames of a phase-contrast time-lapse microscopy sequence. This showed that the in-house image-registration system was the most effective of those tested when tracking non-dividing epithelial cells in low-contrast images, with a successful tracking rate of 95%. The performance of the tracking systems was also evaluated by tracking fluorescently labelled epithelial cells imaged with both phase-contrast and confocal microscopy techniques. The results showed that using fluorescence microscopy instead of phase contrast does improve the tracking efficiency for each of the tested systems. For the in-house software, this improvement was relatively small (<5% difference in tracking success rate), whereas much greater improvements in performance were seen when using fluorescence microscopy with Volocity and ImageJ.
