Contrasted agronomical and physiological responses of five genotypes under soil water deficit in field conditions.

Introduction: Breeding programs have developed high-yielding Coffea arabica F1-hybrids as an adaptation against adverse conditions associated with climate change. However, theresponse to drought of coffee F1 hybrids has seldom been assessed.

Methods: A trial was established with five C.

Genetic-environment interactions and climatic variables effect on bean physical characteristics and chemical composition of Coffea arabica.

Background: The effects of the environment and genotype in the coffee bean chemical composition were studied using nine trials covering an altitudinal gradient [600-1100 m above sea level (a.s.l.

Human Papillomavirus Infection, p16 Expression and Genetic Alterations in Vietnamese Cervical Neuroendocrine Cancer.

Neuroendocrine cervical cancer is a rare subtype of cervical cancer with a highly aggressive malignancy. This study was conducted to analyse the human papillomavirus (HPV) infection and molecular abnormalities in Vietnamese neuroendocrine carcinomas of the uterine cervix. HPV genotyping and p53 mutations were examined using polymerase chain reaction (PCR)-based direct sequencing.

Genetic and epigenetic alterations of the EGFR and mutually independent association with BRCA1, MGMT, and RASSF1A methylations in Vietnamese lung adenocarcinomas.

Genetic and epigenetic alterations importantly contribute to the pathogenesis of lung cancer. In the study, we measured the frequency and distribution of molecular abnormalities of EGFR as well as the aberrant promoter methylations of BRCA1, MGMT, MLH1, and RASSF1A in Vietnamese lung adenocarcinomas. We investigated the association between genetic and epigenetic alteration, and between each abnormality with clinicopathologic parameters.

Dehydroxychlorofusarielin B, an antibacterial polyoxygenated decalin derivative from the marine-derived fungus Aspergillus sp.

Dehydroxychlorofusarielin B (1), a new antibacterial polyoxygenated decalin derivative, and the previously described fusarielins A (2) and B (3) have been isolated from the broth of a marine isolate of the fungus Aspergillus. The structure and absolute stereochemistry of the new compound was determined on the basis of the physicochemical data and X-ray diffraction. Compounds 1-3 exhibited a mild antibacterial activity against Staphylococcus aureus, methicillin-resistant S.
