Uso da linguagem RS em Robótica

This paper presents a Reactive and Synchronous language, called RS, as a tool to develop programs for robots, industrial or mobile, creating a higher abstraction level during the programming task. The RS language is simple to use and has constructions to express parallelism and distribution; those are important features that facilitate the development and maintenance of this kind of programs. ; Este artigo tem...

Advances and drawbacks of the adaptation to serum-free culture of CHO-K1 cells ...

Currently, mammalian cell technology has become the focus of biopharmaceutical production, with strict regulatory scrutiny of the techniques employed. Major concerns about the presence of animal-derived components in the culture media led to the development of serum-free (SF) culture processes. However, cell adaptation to SF conditions is still a major challenge and limiting step of process development. Thus, t...

Screening of the antibacterial activity of phenolic extracts from Portuguese no...

Thermal injury, trauma, chronic ulcerations, pressure or venous stasis result in lost of skin integrity allowing the deposition and colonisation of the injury tissue by a wide range of bacteria. Skin and soft tissues infection are typically colonized by staphylococci or streptococci, but virtually any microorganism may induce tissue inflammation and immune response. The severity of the infection may range from ...

Virulence factors of non-Candida albicans Candida species

Infections caused by Candida species (candidosis) have greatly increased over recent years, mainly due to the escalation of the AIDS epidemic, population ageing, increasing number of immunocompromised patients and the more widespread use of indwelling medical devices. Besides Candida albicans, non-Candida albicans Candida (NCAC) species such as Candida glabrata, Candida tropicalis and Candida parapsilosis are n...

Preliminary evaluation of microcarrier culture for growth and monoclonal antibo...

Large-scale biopharmaceutical production commonly relies on suspension cell cultures that provide higher yields than adherent cultures. However, most mammalian cells grow adherently and therefore need to be adapted to suspended growth, which is not always simple or feasible. Microcarrier culture introduces new possibilities and makes achievable the practical high yield culture of anchorage-dependent cells in su...

Bone Mineral Density After Simultaneous Kidney–Pancreas

ABSTRACT Bone disease and an high risk of fractures are major problems in transplantation. Among diabetic patients undergoing simultaneous kidney–pancreas (SKP) transplantation, there are few studies assessing long-term effects on bone mass. The aim of this study was to evaluate bone mineral density (BMD) over 4 years follow-up after SKP transplantation. Fifty-seven patients had 22.8 5.3 years o...

The role of polysaccharide intercellular adhesin (PIA) in Staphylococcus epider...

The aim of this study was to determine the role of polysaccharide intercellular adhesin (PIA) in Staphylococcus epidermidis adhesion to host tissues and subsequent antibiotic tolerance. The adherence of S. epidermidis 1457 and the mutant defective in PIA production (1457-M10) to urinary epithelium and endothelium was estimated by colony counting. Minimum bactericidal concentration and mean reduction of cellular...

Isolation and characterization of bacteriophages for avian pathogenic E. coli s...

Aims: To isolate and characterize bacteriophages, and to evaluate its lytic performance against avian pathogenic Escherichia coli (APEC) strains with high patterns of antibiotic resistance, in order to select phages for a therapeutic product to treat colibacillosis in chickens. Methods and Results: Bacteriophages were isolated from poultry sewage and tested against 148 O-serotyped APEC strains. The morphologic...
