Spores in fabrics: resistance to disinfection by UVC radiation and ozone

Impact of chitosan on plant tissue culture: recent applications

Chitosan is a very versatile biomaterial with countless applications in different fields. Due to its biodegradability, non-toxicity, and biocompatibility, the use of chitosan is associated with sustainable practices. When applied to plants, in an agricultural context, chitosan induces defense mechanisms, stress resistance, and increased productivity and it has proven to be a feasible alternative to harmful agro...

BIOREF : Laboratório colaborativo para as biorrefinarias

RESUMO: A investigação multidisciplinar, o desenvolvimento e a inovação são pilares fundamentais para alterar o verdadeiro paradigma da economia baseada em recursos fósseis, de modo a conceber e implementar novas economias e mercados orientados para a utilização sustentável da biomassa. De modo a contribuir para uma economia de (muito) baixo carbono e gerar novas cadeias de valor através da utilização sustentáv...

SPLENIC ARTERY ANEURYSM — FOLLOW UP ON TWO CASES OF ENDOVASCULAR STENT GRAFT TR...

Splenic artery aneurysms are rare, but constitute nearly 60% of all visceral arterial aneurysms. Most patients (80%) are asymptomatic and diagnosed incidentally. Rupture risk is estimated in 3%–10%, with a mortality rate of 25—70%. Elective treatment criteria include symptomatic patients, aneurysms larger than 2 cm in diameter or with rapid enlargement and aneurysms of any size diagnosed in patients with portal...

Morphological, physiological and oxidative stress markers during acclimatizatio...

Tuberaria major (Willk.) P. Silva and Rozeira is a critically-endangered rock rose species endemic to Portugal. Because the species needs to be preserved, this study evaluated the morphological and physiological traits of micropropagated T. major plants during acclimatization and field transfer. There were no significant differences between wild and micropropagated plants in the field, although the latter under...

How to monitor the acclimatization of micropropagated plants - From in vitro to...

The high mortality experienced by plants during ex vitro transplantation stage is the major bottleneck in large scale application of micropropagation. The abnormal physiological and anatomical characteristics of micropropagated plantlets require that they should be gradually acclimatized to the environment of the greenhouse or field. Environmental factors, especially relative humidity and irradiance, play a cri...

Molecular cloning and expression analysis of three omega-6 desaturase genes fro...

Two full-length cDNA clones of PoleFAD2 and one full-length cDNA clone of PoleFAD6, encoding omega-6 fatty acid desaturases, the key enzymes for the conversion of oleic into linoleic acid, were isolated from purslane (Portulaca oleracea L.) leaves and seeds. The deduced amino acid sequence of both isoforms of PoleFAD2 showed higher similarities to other microsomal omega-6 desaturases then to PoleFAD6 or other p...
