Abstract
Esophageal squamous cell cancer (ESCC) is a high-grade carcinoma that is treated with multidisciplinary approaches, including chemoradiotherapy (CRT) followed by surgery. Despite some success with these therapies, overall survival remains poor. In order to investigate a newer CRT regimen, we designed a comparative study to evaluate preoperative CRT using docetaxel (DOC) or 5-Fluorouracil and cisplatin (FU+CDDP [FP] therapy) for treatment of resectable ESCC. In a retrospective review of patients with resectable, locally advanced ESCC, 95 patients received preoperative CRT between 2001 and 2007. CRT was administered using either FP (n = 40) or DOC (n = 55). Pathological response and clinical outcomes were compared between the two groups. Hazard ratios and time-to-event analyses were used to assess outcomes; the ratios were controlled by multivariate logistic regression analysis of potential prognostic factors, and survival was presented with Kaplan-Meier curves. In the FP group, a significant curative effect was observed on the basis of pathological examination of postoperative lesions. However, the DOC group presented a significantly better prognosis on the basis of cumulative survival rates. Logistic regression analysis revealed that the presence of five or more lymph node metastases was an independent predictor of reduced survival. Patients with lymph node metastasis exhibited a better prognosis in the DOC group than those in the FP group. Preoperative CRT for locally advanced esophageal cancer using DOC results in similar or better long-term outcomes compared with FP-based CRT. Therefore, CRT using DOC is a promising therapy option for esophageal cancer.

Abstract
In view of recent tremendous advance in astronomical observations in the submillimeter to THz region brought by the Herschel space craft, laboratory high-resolution spectroscopic investigations in that frequency region into unstable molecules, in particular, light hydride ions, are urgently needed. As a part of such endeavor, rotational transitions of H(2)F(+) were observed in the THz-region by using a tunable far-infrared spectrometer. These newly detected lines together with the submillimeter-wave lines obtained previously and the combination differences derived from infrared vibration-rotation lines were subject to a least-squares analysis that yielded a set of molecular constants with much better accuracy. The measured and predicted THz transition frequencies should prove to be a useful probe into detection of interstellar H(2)F(+).

Abstract
Expression and presence of the carbohydrate antigens CA19-9, SLX and STN, and CEA in tissues and serum were examined in 132 patients with early or propria muscle invaded gastric cancer. The seropositive rate was not different in patients with cancer or gastritis. In tumor tissue, the positive rate for these antigens was 28.8% in CA19-9, 9.1% in SLX, 47.0% in STN and 72.9% in CEA. Results showed that gastric cancers, even at an early stage, produce abnormal carbohydrate antigens not detected in normal tissues. However, transfer of antigens into the circulation was not observed in patients with early gastric cancer, suggesting the possibility that number of carcinoma cells may be involved in the transfer of antigens into blood.

Abstract
The genetic differentiation and phylogenetic relationships of 18 indigenous goat populations from seven East Asian countries were analysed based on data obtained from 26 microsatellite DNA markers. The mean number of alleles (MNA) per population ranged from 2.5 to 7.6, with an average of 5.8. Genetic variability estimated from MNA and heterozygosity (H(E) and H(O) ) were relatively low in coastal and island populations. A heterozygous deficiency within populations (F(IS) = 0.054, P < 0.001) and total inbreeding (F(IT) = 0.181, P < 0.01) were observed, and genetic differentiation in the populations (F(ST) ) was 13.4%. The results of Bayesian model-based clustering and a neighbour-joining tree based on Nei's genetic distance showed that Asian goat populations could be subdivided into at least the following three genetic clusters: East Asian, Southeast Asian and Mongolian. These results are in close accordance with conventional morphological and geographical classifications and migration history.

Abstract
AIM The goals of this study were to investigate changes in the sweating and cutaneous vascular responses on the palm and the volar aspect of the index finger during sustained static exercise of increasing intensity and to determine whether the former can be attributed to altered sweat gland activity. METHODS Five male and five female subjects performed maximal voluntary handgrip contractions (MVC: right hand) for 60 s at 20, 35 and 50% MVC (ambient temperature 25 °C, relative humidity 50%). RESULTS The sweat rate and the number of activated sweat glands on the non-exercised hand showed intensity-dependent increases (P < 0.05). At 35 and 50% MVC, finger sweat secretion was significantly higher than on the palm, which was primarily associated with the number of activated sweat glands (P < 0.05). In addition, there was a marked simultaneous decrease in the cutaneous vascular conductance for the finger at 35 and 50% MVC (P < 0.05), but not for the palm. CONCLUSION Our results suggest that a difference exists between intensity-dependent increases of sudomotor responses within more than one glabrous skin site. Specifically, markedly greater sweating occurs on the volar finger than on the palmar surface during sustained static exercise. These differences in sweat rate mainly resulted from changes in the number of activated sweat glands. In addition, intra-segment variations in cutaneous blood flow on the glabrous hand are shown.

Abstract
PURPOSE This study was designed to assess the safety and efficacy of a splenectomy and to analyze the prognostic factors of Müllerian carcinoma with spleen metastasis. METHODS We reviewed the medical records of 11 patients with Müllerian carcinoma who underwent a splenectomy between 1997 and 2007. The treatment outcome of these patients was examined and the possible prognostic factors were investigated by univariate analysis. RESULTS Four and seven patients underwent a splenectomy for primary and recurrent disease, respectively. A complete resection was achieved in eight patients. A blood transfusion was not required and only two mild postoperative complications were observed. The median and five-year survivals of all patients following treatment were 39 months and 39%, respectively. Older patients (> or = 60 years old) and patients with a poor performance status (PS2) had a poorer prognosis by univariate analysis. CONCLUSIONS A splenectomy can be performed safely and effectively during debulking surgery for appropriately selected patients with primary or recurrent Müllerian carcinoma.

Abstract
BACKGROUND The clinical course of abducens nerve palsy associated with skull base tumour is rarely reported. In this study, we examined the post-operative course of abducens nerve palsies associated with various skull base tumours. METHOD Between January 2003 and December 2006, 240 patients with various skull base tumours underwent surgery at Kyushu University Hospital. Among them, nine patients presented with abducens nerve palsies (ten nerves) following surgery. The conditions included two pituitary adenomas, two trigeminal schwannomas and five meningiomas. We evaluated the function of the abducens nerves in these patients on admission, at discharge, and periodically in the outpatient clinic. FINDINGS Four of the abducens nerve palsies already existed prior to surgery, and six of them developed post-operatively. In the four patients with pituitary adenomas and trigeminal schwannomas, all nerves were anatomically preserved and showed complete recovery of function within 6 months after surgery. In contrast, only two of the six palsies in patients with skull base meningiomas showed complete recovery. In three patients with petro-clival meningiomas, the abducens nerves were completely transected during surgery, and one was reconstructed using fibrin glue. This patient remarkably recovered from the abducens nerve palsy within 2 years. CONCLUSIONS The abducens nerve palsies in pituitary adenomas and trigeminal schwannomas showed a better clinical course compared to those in skull base meningiomas. The abducens nerve palsies that occur with skull base meningiomas are less likely to recover. Nevertheless, it is important to preserve the nerves and to perform surgical repair if the nerve is transected.

Abstract
This study describes complete control region sequences of mitochondrial DNA (mtDNA) from 117 Ethiopian cattle from 10 representative populations, in conjunction with the available cattle sequences in GenBank. In total, 79 polymorphic sites were detected, and these defined 81 different haplotypes. The haplotype and nucleotide diversity of Ethiopian cattle did not vary among the populations studied. All mtDNA sequences from Ethiopian cattle converged into one main maternal lineage (T1) that corresponds to African Bos taurus cattle. According to the results of this study, no zebu mtDNA haplotypes have been found in Ethiopia, where the most extensive hybridization took place on the African continent.
