In social insects, cuticular hydrocarbons are involved in species, kin, caste and nestmate recognition. Gas chromatography and mass spectrometry were used to compare the cuticular hydrocarbon composition of workers, males and queens of Melipona bicolor. The cuticular hydrocarbon composition of this species was found to consist mainly of C23, C25:1, C25, C27:1, C27, C29:1 and C29, which are alre...

Implementing the deficit irrigation pattern has become a major strategy in crop production systems. However, using less water than is required to irrigate crops associated with changes plant physiology and lower productivity. Therefore, current research aimed assess integrated effect of humic acid cytokinin on faba bean under deficit. Under two levels (full irrigation, FI DI), treatments (witho...

The diether core membrane lipid sesterterpanyl-phytanyl-glycerol (so-called extended archaeol and often abbreviated C20-C25) is considered as a hallmark of Haloarchaea, clade archaea thriving under extreme high salinities. We here report about occurrence in different saline aquatic settings with salinity ranging from ca. 50 psu (5 % NaCl w/v) to saturation (ca. 350 psu). This demonstrates that ...

Using the DP4f GIAO-NMR method, the stereochemistry of hemicalide was computationally analysed, resulting in a reassignment at C18 as supported by improved NMR shift correlations with a model C13-C25 fragment 23. An advanced C16-C28 subunit 6 of this potent anticancer agent was then synthesised with the revised 18,19-syn relationship.

Lactic acid bacteria are important members of the gut microbiota of humans and animals. Here, we present the genome sequence of Lactobacillus crispatus strain C25, originally isolated from the cecum of 4-week-old chicken fed a standard diet. This isolate represents a potential probiotic strain for poultry.

Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer with a poor prognosis. There is a clinical need for effective, targeted therapy strategies that destroy both differentiated TNBC cells and TNBC cancer initiating cells (CICs), as the latter are implicated in the metastasis and recurrence of TNBC. Chondroitin sulfate proteoglycan 4 (CSPG4) is overexpressed on differen...

Introduction: Cardiomyocytes apoptosis contributes to the development of left ventricular hypertrophy. The Bcl-2 family members are important regulators of mitochondrial pathway of apoptosis. Monoterpenoid phenol –carvacrol– possesses strong antioxidant properties. The present study aimed to evaluate the effect of carvacrol on transcription level of pro-apoptotic (Bad and Bax) and...
