Large-aperture space optical systems are important tools for observing our planet and conducting deep-space scientific research. More requirements have been put forward large-aperture as the depth breadth of related applications continue to increase. However, achieving desired surface accuracy on lightweight materials mirror brings higher demands relevant processing technologies, which increase...

Background: Post-Mastectomy Pain (PPMP) and fatigue are common conditions that can follow surgeries for breast cancer, the most cancer in women. The progressive muscle relaxation technique appears to be effective, affordable, low-risk, adaptable, simple use. Because of frequency PPMP its potential severity, it has received increasing research attention. Aim: To evaluate effectiveness techniques...

Purpose: Dacryocystorhinostomy surgery may result in significant postoperative scarring. Although other surgical techniques have been developed that achieve a better aesthetic result, the ab externo technique remains gold standard for this procedure. We telephone survey to evaluate visual impact of skin scars associated with dacryocystorhinostomy. Methods: 470 patients underwent uncomplicated e...

Abstract Introduction `- In neglected cases of ischemic priapism, there is usually severe corporeal fibrosis that can render penile prosthesis implantation later on extremely difficult. - Although many researchers described different approaches to overcome difficulties during surgery, none them offered satisfactory results. Objective describe a new technique insert large sized in patients suffe...

INTRODUCTION The most common method used for myocardial protection is administering cardioplegic solution in the coronary circulation. Nevertheless, protection may be achieved by intermittent perfusion of the coronary system with patient's own blood. The intermittent perfusion may be performed by multiple sequences of clamping and opening of the aortic clamp or due single clamping and accessory...

This study compared PCR and Western blot techniques in diagnosis of schistosomiasis mansoni. Forty Swiss albino mice were used, thirty two mice were infected with cercariae of S. mansoni and eight mice were kept uninfected which were used as a control. Blood was obtained from four infected mice weekly beginning from the 1st week to the 8th week post infection. The study found that PCR was posit...

BACKGROUND The dual-plane technique has been widely used in augmentation mammaplasty procedures. However, there are some concerns about aesthetic contour maintenance for long time after muscle releasing. This study aims to track and analyze breast dynamic morphological changes after dual-plane breast augmentation with three-dimensional (3D) scanning technique. METHODS Thirteen dual-plane anat...
