Article history: Received 01 July 2015 Accepted 29 July 2015 In the present study, simple and reliable method of histamine analysis was developed, optimized and validated to meet the requirements of fish safety. Histamine in fish samples was extracted with a methanol–phosphate buffer including 2 % TCA solution (50:50, v/v) followed by defatting with hexane after centrifugation at 13,000 rpm. Hi...

Several approaches were examined for extracting the relatively hydrophobic protein recombinant dog gastric lipase (rDGL) expressed in the endosperm of transgenic corn seed. The first approach used minimal processing of the seed before extraction (i.e. simple grinding of whole seed) followed by selective extraction to eliminate 72% of contaminant proteins without compromising rDGL recovery from ...

The dried plant was extracted with dichloromethane and after defatting with hexane, transferred repeatedly on silica columns using dichloromethane-hexane and ethyl acetate-hexane as mobile phases. Finally the fractions were purified by high performance liquid chromatography using a Pack-Sil column and hexane: Ethyl acetate as mobile phase. The structures of the isolated compounds included: cycl...

Major degloving injuries of the lower limb are daunting lesions because they are relatively rare and always produce larger soft tissue defects than direct visual inspection that could be predicted in the emergency room. Enough body of the medical literature supports the excision of the avulsed tissue and replaces it as a full-thickness skin graft. However, almost paradoxically, there is little ...

Objective. To search for articles evaluating the use of tracheostomies (either permanent stomas or tracheostomy tubes) in adult obstructive sleep apnea (OSA) patients and to evaluate the potential for the use of mini tracheostomies as treatment for OSA. Study Design. Systematic review. Methods. Nine databases were searched from inception through July 21, 2015. Results. The overall tracheostomy ...

BACKGROUND A thinned anterolateral thigh (ALT) flap is often harvested to achieve optimal skin resurfacing. Several techniques have been described to thin an ALT flap including an adipocutaneous flap, an adipofascial flap and delayed debulking. METHODS By systematically reviewing all of the available literature in English and French, the present manuscript attempts to identify the common surg...

Solid bar microextraction (SBME), followed by liquid chromatography with fluorescence detection (HPLC-FLD), for the quantification of ochratoxin A in wheat and maize was developed. Ground wheat and maize grains were extracted with acetonitrile-water-acetic acid (79:20:1, v/v/v), followed by defatting with cyclohexane, and subjected to SBME-LC-FLD analysis. SBME devices were constructed by packi...
