An Unusual IgE-Mediated Hypersensitivity: Two Case Reports of Paracetamol Allergy.

Paracetamol is one of the most commonly used analgesic and antipyretic agents worldwide, attributed in part to its excellent safety profile when administered at recommended doses. Paracetamol allergy is not common, and the majority of the reactions are related to the pharmacological action of cyclooxygenase 1 inhibition. Selective and Immunoglobulin E (IgE)-mediated hypersensitivity reactions are rare.

species associated with twig blight and dieback of in Portugal, with description of four new species.

Blueberry, an increasingly cultivated fruit crop in Portugal, is known to be susceptible to twig blight and dieback caused by species of . The diversity of species associated with symptomatic and asymptomatic plants in Portugal was assessed. A multilocus sequence analysis of the rDNA internal transcribed spacer (ITS) region and the translation elongation factor 1-alpha (), β-tubulin (), calmodulin (), and histone 3 () genes revealed the presence of , and four new species, which are described as , and .

Chlorhexidine: a hidden life-threatening allergen.

Chlorhexidine is a commonly used antiseptic and disinfectant in the health-care setting. Anaphylaxis to chlorhexidine is a rare but potentially life-threatening complication. Epidemiologic data suggest that the cases of chlorhexidine allergy appears to be increasing.

Mating type gene analyses in the genus Diplodia: From cryptic sex to cryptic species.

Cryptic species are common in Diplodia, a genus that includes some well-known and economically important plant pathogens. Thus, species delimitation has been based on the phylogenetic species recognition approach using multigene genealogies. We assessed the potential of mating type (MAT) genes sequences as phylogenetic markers for species delimitation in the genus Diplodia.

Mating type genes in the genus Neofusicoccum: Mating strategies and usefulness in species delimitation.

The genus Neofusicoccum includes species with wide geographical and plant host distribution, some of them of economic importance. The genus currently comprises 27 species that are difficult to identify based on morphological features alone. Thus, species differentiation is based on phylogenetic species recognition using multigene genealogies.

Influence of household cooking methods on amino acids and minerals of Barrosã-PDO veal.

The effect of commonly household cooking methods (boiling, microwaving and grilling) on amino acid and mineral (Fe, Mg, K and Zn) contents was investigated in the longissimus lumborum muscle of Barrosã-PDO veal. Fifteen Barrosã purebred calves at 7-8 months of age and an average weight of 177±37 kg were slaughtered. Cooking had a strong effect (P<0.

Biomineralization studies on cellulose membrane exposed to biological fluids of Anodonta cygnea.

The present work proposes to analyse the results obtained under in vitro conditions where cellulose artificial membranes were incubated with biological fluids from the freshwater bivalve Anodonta cygnea. The membranes were mounted between two half 'Ussing chambers' with different composition solutions in order to simulate epithelial surfaces separating organic fluid compartments. The membrane surfaces were submitted to two synthetic calcium and phosphate solutions on opposite sides, at pH 6.

Reproductive cycle and strategy of Anodonta anatina (L., 1758): notes on hermaphroditism.

Freshwater mussels have decreased dramatically in Iberia over the last decades. These animals are responsible for important ecosystem services such as recycling nutrients and improving water clarity. Under this view a better knowledge on the biological features of these animals is extremely important for future conservation and management actions.

Effect of cooking methods on fatty acids, conjugated isomers of linoleic acid and nutritional quality of beef intramuscular fat.

The effect of boiling, microwaving and grilling on the composition and nutritional quality of beef intramuscular fat from cattle fed with two diets was investigated. Longissimus lumborum muscle from 15 Alentejano young bulls fed on concentrate or pasture was analyzed. Cooking losses and, consequently, total lipids, increased directly with the cooking time and internal temperature reached by meat (microwaving>boiling>grilling).

Seasonal variations of pH, pCO2, pO2, HCO3- and Ca2+ in the haemolymph: implications on the calcification physiology in Anodonta cygnea.

A study about the relationship between the physical-chemical parameters and the calcium carbonate balance between the haemolymph fluid and mantle calcareous structures was carried out in Anodonta cygnea. An intense peak of HCO(3) (-) and a highest pH in December-January months may be understood as a preparation period for creating alkaline conditions. An intense pH decrease from January to February in parallel with the HCO(3) (-) reduction seems to indicate the beginning process of carbonate precipitation.
