Stochastic Local Searches (SLS) are a class of meta-heuristics for solving hard combinatorial optimization problems. Common examples of such problems are satisfiability (SAT), travelling salesman problem (TSP), job shop problem (JSP) and vehicle routing problem (VRP). The set of all possible solutions to one of these problems is called the search space. Each point (solution) in the search space...
A multipurpose beamline for tests and developments in the field of x-ray optics and synchrotron radiation instrumentation in general is under construction at the Swiss Light Source (SLS) bending magnet X05DA. The beamline uses a newly developed UHV compatible, 100 μm thick, brazed CVD diamond vacuum window. The very compact cryogenically cooled channel cut Si(111) monochromator and bendable 1:1...
The Role of Hand-Assisted Laparoscopic Surgery in a Right Hemicolectomy for Right-Sided Colon Cancer
PURPOSE The purpose of this study is to evaluate the perioperative and long-term oncologic outcomes of hand-assisted laparoscopic surgery (HALS) and standard laparoscopic surgery (SLS) and assess the role of HALS in the management of right-sided colon cancer. METHODS The study group included 53 patients who underwent HALS and 45 patients who underwent SLS for right-sided colon cancer between ...
BACKGROUND AND AIMS Lynch Syndrome (LS) is caused by pathogenic germline variants in one of the mismatch repair (MMR) genes. However, up to 60% of MMR-deficient colorectal cancer cases are categorized as suspected Lynch Syndrome (sLS) because no pathogenic MMR germline variant can be identified, which leads to difficulties in clinical management. We therefore analyzed the genomic regions of 15 ...
We present a new MLC segmentation algorithm/software for step-and-shoot IMRT delivery. Our aim in this work is to shorten the treatment time by minimizing the number of segments. Our new segmentation algorithm, called SLS (an abbreviation for static leaf sequencing), is based on graph algorithmic techniques in computer science. It takes advantage of the geometry of intensity maps. In our SLS ap...
Yield of streptolysin S (SLS) in streptococcal culture was considerably reduced by procaine, dibucaine, atropine or chlorpromazine at concentrations which scarcely affected production of an extracellular nuclease as well as the bacterial growth. Cerulenin was also inhibitory to SLS formation, but its effect was more pronounced on the nuclease production. By aerobiosis, amount of SLS produced in...
Sjögren-Larsson syndrome (SLS) is a rare type of congenital ichthyosis with neurological problems and intellectual disability. Homozygous mutations in ALDH3A2 gene are known to be responsible for this syndrome. Here, we report an Iranian family with congenital SLS bearing a novel two-base-pair deletion within ALDH3A2 genomic sequence. Our finding expands the mutation spectrum of ALDH3A2 that is...
سابقه و هدف : انحلال یک دارو نقش مهمی را در فراهمی زیستی فرآورده ایفاء می کند . هر تغییر در خصوصیات فیزیک و شیمیایی می تواند سبب تغییر در آزادسازی دارو و در نتیجه سبب تغییر در زیست دستیابی دارو گردد . بنابراین اطلاع از شرایط نگهداری مناسب برای حصول آزاد سازی مورد نظر از دارو دارای اهمیت م یباشد. با precirol مواد و روش ها: قرص های کاربامازپین به روش کمپرسیون مستقیم و با استفاده از پلی اتیلن گلای...
Alcoholic preparations of Arnica montana are widely used for the topical treatment of various inflammatory diseases. Sesquiterpene lactones (SLs) are mainly responsible for their anti-inflammatory activity. Here we have studied the penetration kinetics of Arnica tinctures prepared from dried Arnica flowers originating from different chemotypes as well as of their respective dominating SLs, hele...
In this study, spray drying from aqueous solutions, using the surface-active agent sodium lauryl sulfate (SLS) as a solubilizer, was explored as a production method for co-amorphous simvastatin-lysine (SVS-LYS) at 1:1 molar mixtures, which previously have been observed to form a co-amorphous mixture upon ball milling. In addition, a spray-dried formulation of SVS without LYS was prepared. Energ...
