Background:'Omics' tools provide novel opportunities for system-wide analysis of complex cellular functions. Secondary metabolism is an example of a complex network of biochemical pathways, which, although well mapped from a biochemical point of view, is not well understood with regards to its physiological roles and genetic and biochemical regulation. Many of the metabolites produced by this network such as higher alcohols and esters are significant aroma impact compounds in fermentation products, and different yeast strains are known to produce highly divergent aroma profiles. Here, we investigated whether we can predict the impact of specific genes of known or unknown function on this metabolic network by combining whole transcriptome and partial exo-metabolome analysis.

Background:Breast cancer is the most commonly diagnosed cancer among women and a leading cause of death from cancer in women in Europe. Although breast cancer incidence is on the rise worldwide, breast cancer mortality over the past 25 years has been stable or decreasing in some countries and a fall in breast cancer mortality rates in most European countries in the 1990s was reported by several studies, in contrast, in Greece have not reported these favourable trends. In Greece, the age-standardised incidence and mortality rate for breast cancer per 100.000 in 2006 was 81,8 and 21,7 and although it is lower than most other countries in Europe, the fall in breast cancer mortality that observed has not been as great as in other European countries.

The International Society for Stem Cell Research (ISSCR), representing the world's leading stem cell scientists, urges President-Elect Barack Obama to restore federal funding for embryonic stem cell research in the first 100 days of his presidency. Throughout his campaign Obama has supported stem cell research.

Morria Biopharmaceuticals Plc, a biopharmaceutical company focused on novel, anti-inflammatory drugs, today announced positive data from its ICH compliant Phase II equivalent multi-center study of MRX-4 (n=105) in patients suffering from allergic rhinitis. MRX-4 was given as an intranasal spray formulation.

Atherotech, Inc., a cardio-diagnostic company, today announced it will be exhibiting its VAP(R) Cholesterol Test in booth No. 2918 at the American Heart Association Scientific Sessions 2008. The annual meeting takes place Nov. 8-12 at the Ernest N. Morial Convention Center in New Orleans.

Neuronetics, Inc. announced that a new health economic study evaluating the cost effectiveness of its NeuroStar TMS Therapy system in the treatment of depression was presented at the U.S. Psychiatric and Mental Health Congress in San Diego last week.

An Australian led study found that using testosterone patches helped to increase sex drive in post-menopausal women with low sex drive who were not on hormone replacement therapies.

Background:The ELR+CXC chemokines are multifunctional mediators that are mainly responsible for the recruitment of leucocytes to sites of inflammation and infection. Because of their high sequence identity with mammalian IL-8, fish IL-8-like CXCs have been named as piscine 'IL-8' and included in the ELR+ subgroup, even though there is no reliable functional or evolutionary evidence to support this classification. Results:In this investigation, a homologue of piscine 'IL-8' from black seabream (Acanthopagrus schlegeli), called BS CXC, has been cloned and analyzed. The results revealed that BS CXC has a high gene similarity and tertiary structure similarity with piscine and mammalian CXC chemokines, both ELR-CXC and ELR+CXC, although it has a lower identity with ELR-CXC, compared with ELR+CXC chemokines.

How 'molecular machines' inside cells swing into action to activate genes at different times in a cell's life is revealed in new research published in Molecular Cell. Genes are made of double stranded DNA molecules containing the coded information an organism's cells need to produce proteins. The DNA double strands need to be 'melted out' and separated in order for the code to be accessed.

Growth hormone treatment may significantly increase final height in children diagnosed with short stature, even in cases where the child is not growth hormone deficient, according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

In this primer, we give a review of the inverse problem for EEG source localization. This is intended for the researchers new in the field to get insight in the state-of-the-art techniques used to find approximate solutions of the brain sources giving rise to a scalp potential recording. Furthermore, a review of the performance results of the different techniques is provided to compare these different inverse solutions. The authors also include the results of a Monte-Carlo analysis which they performed to compare four non parametric algorithms and hence contribute to what is presently recorded in the literature.

Background:Several fluorine-18 labelled fluoroamino acids have been evaluated as tracers for the quantitative assessment of cerebral protein synthesis in vivo by positron emission tomography (PET). Among these, 2-[18F]fluoro-L-tyrosine (2-[18F]Tyr) has been studied in mice at a low specific activity. Its incorporation into proteins is fast and metabolism via other pathways is limited. The present in vivo study was carried out in normal awake rats using no-carrier-added 2-[18F]Tyr. Under normal physiological conditions, we have studied the incorporation into proteins and the metabolism of the tracer in different brain areas.Methods:No-carrier-added 2-[18F]Tyr was administered to awake rats equipped with chronic arterial and venous catheters.

Background:In many different countries the Hospital Survey on Patient Safety Culture (HSOPS) is used to assess the safety culture in hospitals. Accordingly, the questionnaire has been translated into Dutch for application in the Netherlands. The aim of this study was to examine the underlying dimensions and psychometric properties of the questionnaire in Dutch hospital settings, and to compare these results with the original questionnaire used in USA hospital settings.Methods:The HSOPS was completed by 583 staff members of four general hospitals, three teaching hospitals, and one university hospital in the Netherlands.

Researchers have found new evidence linking losses in memory and attention to subtle forms of brain damage following mild traumatic brain injury (TBI), which may eventually help in diagnosing when a routine concussion might lead to lasting cognitive problems. TBI affects more than 500,000 Americans each year and over 70 percent of these injuries are considered "mild," usually due to a concussion.

Physician-scientists are studying an herbal supplement that might aid in reducing the symptoms of an enlarged prostate in men. Recent figures show that benign prostatic hyperplasia (BPH) occurs in an estimated 50 percent of men over the age of 50 and in 75 percent of men 80 and older. The research team, led by Dr. Steven A.
