Objectives: Natural orifice translumenal endoscopic surgery (NOTES) represents the first step toward scar-less surgery. The objective of this study is to evaluate early clinical results of transvaginal cholecystectomy using a new technique.
Methods: Institutional review board approval was obtained and transvaginal NOTES cholecystectomy was performed in 12 women for cholelithiasis.
Objective: To evaluate the safety and feasibility of transumbilical laparoscopic surgery using conventional laparoscopic instruments and ports.
Patients And Methods: Since January 2008 we have been using laparoscopic transumbilical procedures. Patient selection was determined by any situation, pathological or not, for which laparoscopy was deemed appropriate as the standard of care in our practice.
Background: Tubal sterilization is one of the most widely used options for female contraception. It can be performed by laparotomy, minilaparotomy, colpotomy, laparoscopy, and hysteroscopy. In this paper, we report the use of the transvaginal endoscopic approach to perform tubal ligation.

Minimum incision techniques in cardiac surgery have been on the rise after their inclusion in videothoracoscopy. Video-assisted minimally invasive cardiac surgery is considered by many centers in the world to be the approach of choice for treatment of mitral and aortic valve diseases. The aim of this is study is to report a case of valve repair in a patient with mitral restenosis after surgical repair 12 years before.

Methods: In this retrospective study, we included all patients submitted to hand-assisted laparoscopic donor nephrectomy and pure laparoscopic live donor nephrectomy between May 2002 and December 2007. The operative data and post-operative courses were reviewed.
Introduction: Minimally invasive cardiac surgery has been performed in major worldwide centers, including procedure such as valves, coronary and congenital surgery.
Objective: To demonstrate our first works with noninvasive cardiac surgery by mean of the experience gained with general and thoracic surgery.
Methods: Whenever possible to carry out a minimally invasive cardiac surgery, this was the approach of choice.
Sanguinarine (SANG) is an alkaloid recognized to have anti-proliferative activity against various human tumour cell lines. No data is available on the susceptibility of advanced malignant melanoma to SANG, although this disease has a very poor prognosis if not detected in time due to the resistance to conventional chemotherapy. The present work was designed to study the nuclear and mitochondrial involvement in the pro-apoptotic effect of SANG in an invasive mouse melanoma cell line.

Recent Findings: Wound healing consists of a perfect and coordinated cascade of events that result in tissue reconstitution. The healing process is common to all wounds, independent of the agent that has caused it.
Electroelution is a widely used methodology for protein purification. In this study, a practical and low-cost system for protein electroelution from stained polyacrylamide gels was developed. For this, a horizontal protein electroelution cuve was constructed with glass plates, 1.

Holstein calves (n = 512) at 2 +/- 1 d of age were randomly assigned to yeast culture (YC, 218 females and 37 males) or control (223 females and 34 males). Yeast culture was fed at 2% of the grain dry matter.

She underwent nephrectomy by transvaginal NOTES using the endoscope by vaginal access and two additional 5-mm trocars in the abdomen. Total procedure time was 170 min and estimated blood loss was 350 cc.

In this paper I elaborate on the reasons why I partially agree with Toomela's ideas, and why I also disagree with some of his arguments. The convergence refers to the need for a radical change concerning the widespread use of methodologies that has been typical of mainstream psychology, which still flavors too positivist and pseudo-quantitative, overlooking the central relevance of theory for scientific development.

The most technically demanding and time-consuming part of this procedure is the urethrovesical anastomosis. Here we describe our technique for the urethrovesical anastomosis with a posterior fixation, using a running suture with two monofilament absorbable sutures.

Because of its ability to arrest the cell cycle and cause apoptosis of several malignant cell lines, it has received attention as a potential anticancer therapeutic agent. Previous studies suggest that mitochondria may be an important target of berberine, but relatively little is known about the extent or molecular mechanisms of berberine-mitochondrial interactions.

We report the performance of a bariatric surgery before the kidney donation in 2 patients in order to improve their medical condition and to reduce their surgical risk to the transplantation procedure. After bariatric surgery, both donors lost more than 30% of their initial corporal weight and their donation procedure was successfully performed, with uneventful postoperative courses.

An array of one- (1HNMR, {1H}-13C NMR, and APT-13C NMR) and two-dimensional NMR techniques (COSY, NOESY, HMQC and HMBC) was used to achieve the structural elucidation and the complete 1H and 13C chemical shift assignments of these natural compounds. In addition, the antifungal activity of these compounds against phytopathogenic and human pathogenic fungi was investigated.

Intake of dry matter was similar among treatments.

A survey was conducted during 2002-2004 as a follow-up to a previous study in 2001 of the cat colony to identify pathogens circulating among the population and to annually follow the status of the cats to analyze morbidity coefficients and associations among infections and infestations identified in the colony. During the 3 years of the present study, 75 cats were sampled at least once, including 44 that were caught and examined only once, 14 that were examined twice, and 17 that were examined three times.
