Abstract The main limitation of the micropropagation camu-camu (Myrciaria dubia) is related to in vitro contamination. In order overcome contamination, effect essential oils was studied as an alternative conventional chemical treatments. This study aimed analyze action from four condiment and medicinal plants (Oregano, Origanum vulgare L.; Garlic, Allium sativum Citronella, Cymbopogon nardus L....

Fish is present in the Brazilian diet and represents an important participation protein consumption. The use of highly toxic pesticides still tolerated Brazil despite being banned many parts world. This study records traces contamination by Persistent Organic Pollutants (POPs) at Guanabara Bay Rio de Janeiro (Brazil). Our results indicate that local production widespread such chlorinated compou...

The problem of antibiotic resistance emerging from the use and misuse of antibiotics in veterinary practice was considered as long ago as the 1960s by the famous Swann Committee. 1 What seems to be less well understood, and certainly less well documented, is the use of antimicrobials in the world of plant science. Antibiotics have been widely used in the control of contamination of micropropaga...

With the increasing usage of sensitive PCR technology for pharmacogenetics, cross contamination becomes a significant concern. Researchers employed techniques which basically include replacing laboratory equipment after each sample preparation; however, there are no recommended guidelines. In the present work we wanted to evaluate the risk of cross contamination during tissue processing using t...

We evaluated four decontamination methods and one nondecontamination procedure in combination with four egg-based media for the primary isolation of Mycobacterium ulcerans from tissue specimens. With mycobacterial recovery and contamination rates of 75.6 and 2.4%, respectively, the combination of the oxalic acid decontamination method with Lowenstein-Jensen medium supplemented with glycerol yie...

Enzymically inactive acetyl-CoA carboxylase [acetyl-CoA:carbon-dioxide ligase (ADP-forming), EC 6.4.1.2] was found as a component of bovine milk-fat-globule membrane (MFGM). Acetyl-CoA carboxylase was present in MFGM at a higher concentration than in cytosolic or mitochondrial fractions of bovine mammary tissue, which makes it unlikely that its presence was due to simple contamination by these ...

background: development of tissue engineering and regenerative medicine has led to designing scaffolds and their modification to provide a better microenvironment which mimics the natural niche of the cells. gelatin surface modification was applied to improve scaffold flexibility and cytocompatibility. methods: plla/pcl aligned fibrous scaffold was fabricated using electrospinning method. adscs...
