Comparison and correlation between chemical profiles of cephalic salivary glands and cuticle surface of workers of apis mellifera (Hymenoptera, Apidae)
(2017-01-01)
The cuticle surface of insects displays functions in communication, such as recognition. It is known that oenocytes are responsible for the origin of the compounds found in the epicuticle. Secretion of exocrine glands might ...
Determination of Linear Response in the Detection of Aroma Compounds by Atmospheric Pressure Ionization−Mass Spectrometry (API-MS)
(American Chemical Society, 2005-02)
Linearity and detection thresholds of atmospheric pressure ionization−mass spectrometry (API-MS) were determined for 11 aroma compounds in air at concentrations ranging from 50 ppb to ∼450 ppm (moles of volatile per mole ...
A Comparative Study of Hydrogen-Induced Cracking Resistances of API 5L B and X52MS Carbon Steels
(2018-01-01)
Susceptibility to hydrogen-induced cracking of API 5L B and X52MS low-carbon steels in NACE 177-A, 177-B, and 284-B solutions has been investigated by the present work. A metallographic analysis of these steels was performed ...
Oxytetracycline and florfenicol concentrations in food-additive premixes authorised for broiler chickens: assessing degree of agreement with manufacturers labelling
(MDPI, 2021)
Antimicrobials premixes are the presentation of choice to administer drugs simultaneously
to groups of animals in intensive husbandry systems that require treatment for pathologies of
bacterial origin. Among the premixes ...
Jelleines: a family of antimicrobial peptides from the Royal Jelly of honeybees (Apis mellifera)
(Elsevier B.V., 2004-06-01)
Four antimicrobial peptides were purified from Royal Jelly of honeybees, by using reverse phase-HPLC and sequenced by using Q-Tof-MS/MS: PFKLSLHL-NH2 (Jelleine-I), TPFKLSLHL-NH2 (Jelleine-II), EPFKLSLHL-NH2 (Jelleine-III), ...

Proteome and phosphoproteome of Africanized and European honeybee venoms
(2013-09-01)
Honey bee venom toxins trigger immunological, physiological, and neurological responses within victims. The high occurrence of bee attacks involving potentially fatal toxic and allergic reactions in humans and the prospect ...
Profiling the proteome complement of the secretion from hypopharyngeal gland of Africanized nurse-honeybees (Apis mellifera L.)
(Elsevier B.V., 2005-01-01)
The protein complement of the secretion from hypopharyngeal gland of nurse-bees (Apis mellifera L.) was partially identified by using a combination of 2D-PAGE, peptide sequencing by MALDI-PSD/MS and a protein engine ...
