This study explored the self-reported prevalence of cardiovascular disease (CVD) and accompanying risk factors among 165 male retirees 43 years and older (M= 56.2, SD= 7.1) …

Pharmacological Neuroenhancement in the Field of Economics-Poll Results from an Online Survey.

INTRODUCTION: The use of over-the-counter, prescription, and illicit drugs to increase attention, concentration, or memory-often called (pharmacological) neuroenhancement-shows a broad range of prevalence rates among students. However, very little data is available on neuroenhancement among employed persons. The aim...

Identification of new sesquiterpenoids in cephalic secretion of cuckoo bee,Nomada lathburiana (Apoidea, Anthophoridae).

Journal of chemical ecology

Francke W, Krohn S, Tengö J.
PMID: 24258806
J Chem Ecol. 1991 Mar;17(3):557-66. doi: 10.1007/BF00982126.

A series of new sesquiterpene ketones and norsesquiterpene ketones could be identified from the cephalic secretion of females of the cuckoo bee,Nomada lathburiana (K.). The major component proved to be 2,6,10-trimethylundeca-(5E)-2,5,9-trien-4-one. Large amounts of high-boiling-point straight-chain hydrocarbons serve as...

Intranidal worker reactions to volatile compounds identified from cephalic secretions in the stingless bee,Scaptotrigona postica (Hymenoptera, Meliponinae).

Journal of chemical ecology

Engels E, Engels W, Schröder W, Francke W.
PMID: 24301816
J Chem Ecol. 1987 Feb;13(2):371-86. doi: 10.1007/BF01025897.

From pentane extracts of worker heads of the stingless bee (Scaptotrigona postica), 70 volatile compounds were identified by combined gas chromatographic-mass spectroscopic analyses. A bioassay was developed to evaluate intranidal reactions of workers to synthetic volatiles. Thirty-six of the...

Pheromones in white pine cone beetle,Conophthorus coniperda (schwarz) (Coleoptera: Scolytidae).

Journal of chemical ecology

Birgersson G, Debarr GL, de Groot P, Dalusky MJ, Pierce HD, Borden JH, Meyer H, Francke W, Espelie KE, Berisford CW.
PMID: 24234016
J Chem Ecol. 1995 Feb;21(2):143-67. doi: 10.1007/BF02036648.

Female white pine cone beetles,Conophthorus coniperda, attacking second-year cones of eastern white pine,Pinus strobus L., produced a sex-specific pheromone that attracted conspecific males in laboratory bioassays and to field traps. Beetle response was enhanced by host monoterpenes. The female-produced...

Insect pheromone biosynthesis: stereochemical pathway of hydroxydanaidal production from alkaloidal precursors in Creatonotos transiens (Lepidoptera, Arctiidae).

Proceedings of the National Academy of Sciences of the United States of America

Schulz S, Francke W, Boppré M, Eisner T, Meinwald J.
PMID: 11607415
Proc Natl Acad Sci U S A. 1993 Jul 15;90(14):6834-8. doi: 10.1073/pnas.90.14.6834.

The mechanism by which the moth Creatonotos transiens produces its male pheromone, (7R)-hydroxydanaidal, from heliotrine, an alkaloidal precursor of opposite (7S) stereochemistry, was investigated. Specifically deuteriated samples of heliotrine and epiheliotrine were prepared and fed to C. transiens larvae,...

The secretion of the ventral glands in Cladius, Priophorus and Trichiocampus sawfly larvae.

Biochemical systematics and ecology

Boevé JL, Heilporn S, Dettner K, Francke W.
PMID: 10913847
Biochem Syst Ecol. 2000 Nov 01;28(9):857-864. doi: 10.1016/s0305-1978(00)00008-9.

The volatile secretion from ventral glands of the larvae of Cladius pectinicornis, Priophorus morio, P. pallipes and Trichiocampus grandis was found to be principally composed of long-chain acetogenins, in majority of the esters and hydrocarbons, with more than 15...

Synthetic polycyclic musk fragrances are mainly represented by the compounds HHCB (Galaxolide(TM)) and AHTN (Tonalide(TM)). Because of their volume of use and their bioaccumulation potential, there is concern with respect to their environmental safety. HHCB and AHTN are chiral...

An approach to the utilisation of CO2 as impregnating agent in steam pretreatment of sugar cane bagasse and leaves for ethanol production.

Biotechnology for biofuels

Ferreira-Leitão V, Perrone CC, Rodrigues J, Franke AP, Macrelli S, Zacchi G.
PMID: 20384996
Biotechnol Biofuels. 2010 Apr 12;3(1):7. doi: 10.1186/1754-6834-3-7.

BACKGROUND: The conditions for steam pretreatment of sugar cane bagasse and leaves were studied using CO2 as an impregnating agent. The following conditions were investigated: time (5 to 15 min) and temperature (190 to 220 degrees C). The pretreatment...

Desmosomal molecules in and out of adhering junctions: normal and diseased States of epidermal, cardiac and mesenchymally derived cells.

Dermatology research and practice

Dermatol Res Pract. 2010;2010:139167. doi: 10.1155/2010/139167. Epub 2010 Jun 30.

Current cell biology textbooks mention only two kinds of cell-to-cell adhering junctions coated with the cytoplasmic plaques: the desmosomes (maculae adhaerentes), anchoring intermediate-sized filaments (IFs), and the actin microfilament-anchoring adherens junctions (AJs), including both punctate (puncta adhaerentia) and elongate...
