To achieve the production of a thermostable DNA polymerase free from bacterial DNA contamination, we developed eukaryote-made thermostable DNA (Taq) polymerase. The novel eukaryote-made thermostable DNA polymerase resolves the problem of contaminating bacterial DNA in conventional bacterially made thermostable DNA polymerase as a result of its manufacture and incomplete purification. Using eukaryote-made thermostable DNA polymerase, the sensitive and reliable detection of bacteria becomes feasible for large fields, thereby making the development of a wide range of powerful applications possible. 相似文献

We describe a newly modified technique, which we term “less invasive quick replacement” (LIQR) for type A acute aortic dissection
(AAD). After cooling to a rectal temperature of 28°C without any cerebral perfusion, circulating blood in the cardiopulmonary
bypass (CPB) circuit was warmed up to 40°C during open distal anastomosis. As soon as the distal anastomosis was completed,
rapid rewarming was initiated by perfusing blood at 40°C. The average CPB and total operative times were 71.8 ± 9.6 and 130.6
± 7.7 min, respectively. The shortest operative time was 101 min from skin incision to skin closure. All patients were weaned
off the ventilator within 12 h of surgery. The postoperative hospital stay was 9.3 ± 1.2 days. There was no incidence of cerebral
damage or hospital mortality. Our initial results showed LIQR to be safe and effective. 相似文献

Tension-free herniorraphies were carried out using either the Mesh Plug repair (M-P) or Perfix plug technique (P-P) in four
patients with cirrhosis. Three patients had a lateral inguinal hernia, and the other had bilateral inguinal and femoral hernias.
The patients’ ages ranged from 55 to 80 years. The Child-Pugh classifications showed that one was A, two were B, and one was
C. The main complaint in two patients was a difficult reduction and the others had discomfort. An M-P was performed in the
three patients with inguinal hernias and an M-P was performed for the femoral hernias and a P-P for the inguinal hernias in
the patient with both inguinal and femoral hernias. Two patients had fluid collection under the incision and one of them required
a single puncture. However, the others had no related complications after the operation. One patient died due to liver failure
without recurrence of the groin hernias 31 months after the operation. The others had no recurrence and no related symptoms
from 5 to 52 months after the operation. 相似文献

Purpose
The administration of stimuli to the ileum inhibits upper gastrointestinal motility. The aim of this study was to determine whether a total colectomy can alter this motor inhibitory effect. 相似文献995.

Objectives The purpose of this study was to identify important prognostic factors related to the status of a pancreatic tumor, its treatment,
and the patient’s general condition.
Methods Between April 1992 and December 2006, 140 patients underwent a pancreatic resection for invasive ductal carcinoma. Prognostic
factors were defined by univariate and multivariate analyses.
Results The study included 103 tumors in the head of the pancreas and 37 tumors in the body or tail. The median survival time and
the actuarial 5-year survival rate for all patients were 14.5 months and 12.3%, respectively. Using the significant prognostic
factors identified by univariate analysis, multivariate analysis revealed that a preoperative serum CA19-9 concentration >100
U/ml (HR = 1.84, p = 0.0074), a tumor size >3 cm (HR = 1.74, p = 0.0235), venous involvement (HR = 2.39, p = 0.0006), a transfusion requirement of ≥1000 ml (HR = 2.23, p = 0.0006), and a serum albumin concentration on 1 postoperative month (1POM) < 3 g/dl (HR = 2.40, p = 0.0009) were significant adverse prognostic factors. The presence of hypoalbuminemia on 1POM significantly correlated with
a longer surgical procedure (p = 0.0041), extended nerve plexus resection around the superior mesenteric artery (p = 0.0456), and a longer postoperative hospital stay (p = 0.0063).
Conclusion To improve long-term survival, preserving the patient’s general condition by performing a curative resection with a short
operation time and minimal blood loss should be the most important principle in the surgical treatment of pancreatic cancer. 相似文献

Abstract: In order to develop a diaphragm-type ventricular assist device (VAD), we studied the flow field change following structural modifications. We devised a center flow-type pump by putting a small projection on the center of the housing and/or diaphragm to provide a center in the flow field, and examined the following four types of VADs: N type without a projection, D type with a projection on the diaphragm, H type with a projection on the housing, and DH type with projections on both the diaphragm and housing. Computational fluid dynamics (CFD) was used for flow simulation. Particle image velocimetry (PIV) was also used to verify the reliability of the CFD method and to determine how the flow field changes in the presence of a projection. The results of the PIV and CFD analyses were comparable. The placement of a projection on the housing was most effective in rectifying the flow field. 相似文献

Introduction
Because the donor shortage is extremely severe in Japan because of a strict organ transplantation law, special strategies must be established to maximize heart transplantation (HTx) and lung transplantation (LTx) opportunities. The purpose of this study was to review our strategies to identify and manage heart and lung donors.Method
Transplantation doctors themselves assessed their own donor heart and lung function before starting the procurement operation; skillful staff surgeons harvested the organs. Since November 2002, a special transplantation consultant doctor assessed donor organ function to identify useful organs and intensively cared for the donor to improve cardiac and lung function.Results
Only 63 brain-dead donors have been available in Japan. However, 49 HTx (77.7%) and 39 LTx (19 bilateral and 20 single) were performed from 36 donors (57.1%). Thirty-six HTx donors were marginal, requring sustained high doses of inotropes (n = 26), low left ventricular ejection fraction (n = 5), cardiopulmonary resuscitation (n = 15), and age older than 55 years (n = 6). Twenty LTx donors had infected sputa or showed pneumonia using chest X-ray. None of 49 HTx recipients died of primary graft failure (PGF). Patient survival at 3 years after HTx was 98.0%. Although 5/39 LTx died early, including 2 of PGF, patient survival rate at 3 years was 66.9%.Conclusion
Although the number of cases was still small, the availability of hearts and lungs has been high and the transplantation outcomes were acceptable. These strategies may be useful to maximize HTx/LTx opportunities. 相似文献1000.

Mutations of the gene encoding the α2 subunit of the neuronal sodium channel, SCN2A, have been found in benign familial neonatal-infantile seizures (BFNIS). In Dravet syndrome, only one nonsense mutation of SCN2A was identified, while hundreds of mutations were found in the paralogue gene, SCN1A, which encodes the α1 subunit. This study examines whether SCN2A mutations are associated with Dravet syndrome. We screened for mutations of SCN1A, SCN2A and GABRG2 (the gene encoding γ2 subunit of the GABAA receptor) in 59 patients with Dravet syndrome and found 29 SCN1A mutations and three missense SCN2A mutations. Among the three, one de novo SCN2A mutation (c.3935G>C: R1312T) identified in a patient was thought to affect an arginine residue in a voltage sensor of the channel and hence, to be pathogenic. This finding suggests that both nonsense mutations and missense SCN2A mutations cause Dravet syndrome. 相似文献
