Safety and efficacy of a feed additive consisting of lactic acid produced by Weizmannia coagulans (synonym Bacillus coagulans) DSM 32789 for all animal species except for fish (Jungbunzlauer SA). [PDF]
Abstract Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of lactic acid produced by a non‐genetically modified strain of Weizmannia coagulans (synonym of Bacillus coagulans) (DSM 32789) for all animal ...

Abstract Cerambyx welensii Küster (Coleoptera: Cerambycidae) is a wood‐borer responsible for the decline of Mediterranean oaks in open woodlands. To establish that contact pheromones are involved in mate recognition of C. welensii, we extracted the cuticular hydrocarbons by solid phase microextraction at pre‐reproductive, beginning and ending of the ...

Seal materials in flexible plastic food packaging: A review
This review on heat seal materials aims to give a literature overview to optimize the material selection in flexible food packaging and obtain seals with desired tightness and strength. The simplified representation of temperature dependence of hot tack and seal strengths of thermoplastic films shows low values below seal initiation temperature (A ...

An efficient Lewis acid‐assisted asymmetric carbonyl‐ene reaction to set the 1α‐hydroxyl functionality of enol‐triflate, precursor of the A‐ring of the hormone calcitriol and its 1α‐hydroxyderivatives, is described. Abstract The secondary parallel hypercalcemic effects associated with the treatment of several hyperproliferative diseases with the ...

Solution‐based methods are reviewed for the preparation of representative, multifunctional noncentrosymmetric oxide nanocrystals with perovskite and nonperovskite crystalline structures. Elucidation of the reaction pathways and crystallization mechanisms is a prerequisite for improving their resulting morphology in the future and aggregation state for ...

The preparation of enantiomerically pure cis‐C‐glycosyl compounds, through a long‐range epimerization at C5 of readily accessible d‐ or l‐carbohydrates, by means of a remote reductive radical sequence was described. A comparative study of the radical process promoted by a tin reagent or with photoredox conditions was also performed.

Photoswitchable Norbornadiene–Quadricyclane Interconversion Mediated by Covalently Linked C60
Switching! The synthesis of several norbornadiene (NBD)–fullerene adducts is herein reported. Within these new hybrid systems, the photochemical isomerization of NBD is combined with the electron affinity of C60. This enables the selective light‐induced isomerization of the NBD derivative to its corresponding quadricyclane (QC) counterpart and the back

Genomics analysis of hexanoic acid exposure in Drosophila species [PDF]
Abstract Drosophila sechellia is a dietary specialist endemic to the Seychelles islands that has evolved to consume the fruit of Morinda citrifolia. When ripe, the fruit of M. citrifolia contains octanoic acid and hexanoic acid, two medium-chain fatty acid volatiles that deter and are toxic to generalist insects.
