Abstract
AbstractLight-weight, large-area and flexible solar cells and modules were developed. Roll-to-roll processes including an improved film deposition process named “Stepping-roll process” are used to fabricate large-area hydrogenated amorphous silicon-based solar cells in succession on plastic film substrates. A unique device having through-hole contacts was developed and applied to simplify the production processes and to generate high voltage using connection in series. Production technologies, such as (1) light-weight and large area module fabrication, (2) plasma condition controlled chemical vapor deposition, (3) low substrate temperature selective reactive sputtering, and (4) large-area uniform transparent conductive oxide film deposition are reviewed.

Abstract
Alpha-lactalbumin (alpha-LA) was glycated with maltopentaose (MP) through the Maillard reaction (MP-alpha-LA) and subsequently phosphorylated by dry heating in the presence of pyrophosphate to investigate its structure and physiological functions. Glycation occurred effectively, and the sugar content of alpha-LA increased by approximately 22.3% through the Maillard reaction. The phosphorylation of MP-alpha-LA was enhanced with an increase in the dry-heating time from 1 to 5 d, and the phosphorous content of MP-alpha-LA increased by approximately 1.01% by dry heating at pH 4.0 and 85 degrees C for 5 d in the presence of pyrophosphate. The electrophoretic mobility of alpha-LA increased with an increase in the phosphorylation level. The circular dichroism spectra showed that the change in the secondary structure of the alpha-LA molecule by glycation and subsequent phosphorylation was slight. However, the Trp fluorescence intensity was increased by phosphorylation after glycation. In addition, the differential scanning calorimetry thermograms of alpha-LA showed that the denaturation temperature of MP-alpha-LA was decreased by phosphorylation. These results indicated that molten (partially unfolded) conformations of alpha-LA were formed by dry heating in the presence of pyrophosphate after glycation. The anti-alpha-LA antibody response was significantly reduced by glycation and subsequent phosphorylation. The suppressive effect of alpha-LA on the production of proinflammatory cytokines such as IL-6 and tumor necrosis factor-alpha from THP-1 cells after stimulation with lipopolysaccharide was significantly enhanced by glycation with MP and was further enhanced by phosphorylation after glycation. The Ca phosphate-solubilizing ability of alpha-LA was enhanced by phosphorylation. The apoptotic activity of alpha-LA was reduced by glycation and subsequent phosphorylation. These results suggest that phosphorylation by dry heating in the presence of pyrophosphate after glycation with MP through the Maillard reaction is a useful method for improvement of the physiological functions of alpha-LA.

Abstract
Cell death is a physiological and fundamental process in normal organogenesis. During the development of the nervous system, cell death or apoptosis occurs in early and late developmental time periods, affecting neural precursors and neurons respectively. In the development of the enteric nervous system (ENS), however, apoptosis of neurons has not been detected, a feature unique to enteric neurons. In this issue of Neurogastroenterology and Motility, Wallace et al. focused on an early phase of ENS development and identified apoptotic cell death in vagal neural crest cells, the primary cellular source for the ENS. Introduction of an antiapoptotic molecule in the vagal neural crest and its derivatives resulted in the overproduction of neurons in the foregut. Thus, unlike the neurons themselves, ENS precursors do undergo apoptosis, which may, by regulating the size of the ENS precursor pool, be a crucial factor in determining the final cell number in the ENS.

Abstract
The enteric nervous system (ENS) is the largest and most complicated subdivision of the peripheral nervous system. Its action is necessary to regulate many of the functions of the gastrointestinal tract including its motility. Whilst the ENS has been studied extensively by developmental biologists, neuroscientists and physiologists for several decades it has only been since the early 1990s that the molecular and genetic basis of ENS development has begun to emerge. Central to this understanding has been the use of genetic model organisms. In this article, we will discuss recent advances that have been achieved using both mouse and zebrafish model genetic systems that have led to new insights into ENS development and the genetic basis of Hirschsprung's disease.

Abstract
OBJECTIVES Conventional nerve conduction studies (NCS) are not sensitive to detect mild diabetic neuropathy. In order to detect subtle changes, we compared the conventional NCS with the relative refractory period (RRP) measurement of the median sensory nerve action potential by a paired stimulation method. METHODS Subjects were 29 diabetic patients whose conventional NCS were all normal. They were divided into two groups: neurologically symptomatic and asymptomatic groups. Twenty-eight age-matched control subjects were also studied. RESULTS The RRP of the symptomatic diabetic patients (5.9 +/- 0.5 ms) and that of the asymptomatic patients (5.6 +/- 0.5 ms) was significantly longer than that of the control subjects (4.9 +/- 0.6 ms). There was no significant difference in RRP between the symptomatic and asymptomatic patients. This may be due to the fact that NCS reflects mainly large myelinated fiber function and early symptoms represent mainly thin myelinated or unmyelinated fiber function. CONCLUSIONS The RRP measurement could reveal some mild involvement of peripheral nerves undetectable by conventional NCS, even though they caused no clinical symptoms.

Abstract
We evaluated the results of rotational acetabular osteotomy in 44 hips (42 patients) with advanced osteoarthritis secondary to developmental dysplasia. The mean age of the patients at surgery was 43.4 years (30 to 59) and the mean follow-up was 12.1 years (8 to 19). The mean Merle d'Aubigné clinical score improved from 10.8 points (8 to 15) pre-operatively to 13.5 points (6 to 18) at follow-up. Radiologically, this procedure produced adequate improvement regarding cover of the femoral head. At follow-up, the osteoarthritic stage assessed using the Japanese Orthopaedic Association grading, was improved in 11 hips (25%), unchanged in 22 (50%) and had progressed in 11 (25%). The mean pre-operative roundness index of the femoral head was significantly different in the 33 hips which had improved or maintained their osteoarthritic stage compared with the 11 which had progressed (53.7% vs 63.7%; p < 0.001). Osteoarthritis with a round femoral head is considered to be an indication for rotational acetabular osteotomy, even in advanced stages of the disease.

Abstract
INTRODUCTION We compared the functional and radiological results of a rotational acetabular osteotomy (RAO) with and without a resection of the lateral edge of the acetabulum. The purpose of the resection was to obtain good joint congruency. MATERIALS AND METHODS RAO was performed on 71 hips to treat advanced coxarthrosis caused by acetabular dysplasia. RAO without a resection (non-resection group) was performed in 54 patients (57 hips) with a median age of 43.1 years. The remaining 14 patients (14 hips), who had a median age of 44.6 years, received RAO with a resection of the lateral edge of the acetabulum (resection group). RESULTS The average postoperative total hip joint score was better than the average preoperative score in the non-resection group (P < 0.001), but not in the resection group. In the resection group, all hips displayed progressive osteoarthritic change and ten hips had chondrolysis of the hip joint and a collapse of the transferred acetabulum within 3 years. In the non-resection group, 15 hips showed progressive osteoarthritic change, 24 hips had no change, and 18 hips showed a decrease in the osteoarthritic stage. CONCLUSION Our findings demonstrated that resection of the lateral edge of the acetabulum is not a useful adjunct to the RAO procedure for the treatment of advanced coxarthrosis.

Abstract
Beta-lactoglobulin (beta-Lg) was glycated with maltopentaose and subsequently phosphorylated by dry-heating in the presence of pyrophosphate to investigate the structural and functional properties of phosphorylated beta-Lg. The circular dichroism spectra showed that the change of the secondary structure in the beta-Lg molecule by glycation and subsequent phosphorylation was small. The differential scanning calorimetry thermograms of beta-Lg showed that the denaturation temperature of the most stable domain was only slightly affected, whereas the retinol-binding activity of beta-Lg was somewhat reduced by glycation and subsequent phosphorylation. These results indicated that the conformational changes of the beta-Lg molecule by glycation and subsequent phosphorylation were mild. The anti-beta-Lg antibody response was somewhat reduced by glycation, but significant changes were not observed by phosphorylation. Although the stability of beta-Lg against heat-induced insolubility was improved by glycation alone, it was further enhanced by phosphorylation. The calcium phosphate solubilizing ability of beta-Lg was enhanced by phosphorylation following glycation.
