Doença Hemolítica Perinatal — Caso Clínico

A doença hemolítica perinatal resulta da passagem placentária de anticorpos do tipo IgG contra antigénios eritrocitários fetais, dando origem a hemólise. A incompatibilidade Rh(D) é a responsável por cerca de 94% casos. As incompatibilidades por antigénios atípicos (anti-c, anti-Kell) apesar de raras, dão origem a quadros graves.Os autores apresentam um caso clínico de isoimunização anti-c num prematuro, I° fil...

Development and validation of analytical method for sulfonamide residues in egg...

Liquid chromatography- electrospray ionization - tandem mass spectrometry (LC-ESI-MS/MS) was used to simultaneous determination of ten sulfonamide (SAs) residues (sulfacetamide, sulfathiazole, sulfamerazine, sulfamethazine, sulfamethoxypyridazine, sulfamethizole, sulfachloropyridazine, sulfamethoxazole, sulfadimethoxine and sulfaquinoxaline) in eggs. Samples were extracted with acetonitrile and the supernatants...

Cytocompatibility of chitosan and collagen-chitosan scaffolds for tissue engine...

In this work, chitosan and collagen-chitosan porous scaffolds were produced by the freeze drying method and characterized as potential skin substitutes. Their beneficial effects on soft tissues justify the choice of both collagen and chitosan. Samples were characterized using scanning electron microscope, Fourier Transform InfraRed Spectroscopy (FTIR) and thermogravimetry (TG). The in vitro cytocompatibility of...

Estratégias de uso de água salobra na produção de alface em hidroponia NFT

Plantas de alface crespa 'Verônica' foram cultivadas em condições hidropônicas, objetivando avaliar três diferentes estratégias de emprego de águas salobras: 1) águas salobras para reposição das perdas por evapotranspiração (ETc) e água doce para o preparo da solução nutritiva (SN); 2) águas salobras para o preparo da SN e água doce para reposição da ETc; 3) águas salobras para o preparo da SN e reposição da ET...

Impact of pelvic radiotherapy on female sexuality

PURPOSE: To assess physical and psychological morbidity, sexual functioning and social and relationship satisfaction among women treated with pelvic radiotherapy. METHODS: Observational (case-control) study of 199 women: 98 submitted to pelvic radiotherapy for the treatment of uterine, rectal or anal cancers and 101 without a personal history of cancer and similar socio-demographic variables. These completed a...

Nd isotope composition of the terrigenous component of sediments as a tracer fo...

The OMEX core KC 024-19 was studied aiming at to assess the influence of climate changes on the origin and transport of the sediments of the Galician continental slope, in the last 40 ka. The results show that sea level variation played a major role in the supply of the terrigenous sediments coming from the nearby continental areas, whose basement has a Variscan age. Additionally, coarse-grained clastic materia...

Traumatic brain injury and shaken baby syndrome.

Shaken baby syndrome is a serious form of physical child abuse, which is frequently overlooked. It is defined as vigorous manual shaking of an infant who is being held by the extremities or shoulders, leading to whiplash-induced intracranial and intraocular bleeding and no external signs of head trauma. This syndrome is seen most commonly in children under 2 years, mainly in children under 6 months. This articl...

Benefícios da Terapêutica de Ressincronização Cardíaca na «Miocardiopatia Muito...

INTRODUCTION: Recent clinical trials have studied parameters that could predict response to cardiac resynchronization therapy (CRT) in patients with advanced heart failure. Left ventricular end-diastolic dimension (LVEDD) is regarded as a possible predictor of response to CRT. OBJECTIVE: To study the response to CRT in patients with very dilated cardiomyopathy, i.e. those at a more advanced stage of the pathol...

Hidden allergens in food

Food allergies are considered a signif icant food-safety issue, whose preval ence has been increasing mainly in industrialized countries. The presence of non-declared allergens in food due to contamination during production or to misleading labeling represents a potential high risk for allergic individuals. To protect sensitized individuals, highly sensitive methods are required, especially for processed food s...
