  • The past decade has seen the field of proteomics expand from a highly technical endeavor to a widely utilized technique. The objective of this book is to highlight the ways in which proteomics is currently being employed to address issues in the biological sciences. Although there have been significant advances in techniques involving the utilization of proteomics in biology, fundamental approaches involving basic sample visualization and protein identification still represent the principle techniques used by the vast majority of researchers to solve problems in biology.

  • HeR2 status. Your pathology report usually includes the cancer’s HER2 status. The HER2 gene is responsible for making HER2 proteins. These proteins are receptors on breast cells. Under normal circumstances, HER2 receptors help control how a breast cell grows, divides, and repairs itself. But in about 25% of breast cancers, the HER2 gene can become abnormal and make too many copies of itself (amplification of the HER2 gene). Amplified HER2 genes command breast cells to make too many receptors (overexpression of the HER2 protein).

  • Extrusion processing is widely utilized in the food and feed industries for the manufacture of value-added products. Extrusion processing is a versatile technology producing a wide range of products, including confectionery products, pasta, ready-to-eat (RTE) cereals, flat bread, snack products, texturized proteins, and pet foods.

  • small water bodies like ponds now contributes 80% of the country’s inland fish production. However, future growth in freshwater aquaculture to meet rising demand for fish is likely to be constrained by limited supplies of land for digging new ponds and of water to fill them. In this context, reservoirs offer immense scope for increasing fish production.

  • Certain works like agriculture or pests killing represent the biggest risks of acute intoxication, while there is a latent danger for the population at large in their food chain (Ospina et al, 2009) (Thundiyil et al, 2008). The agricultural development model in Colombia is mainly based upon the use of agro chemicals and according data reported by the Public Health Surveillance System of Colombia (SIVIGILA), there were in 2008 6.650 intoxication cases for the use of pesticides followed by 7.405 cases in 2009 and 8.

  • Biodiversity is fundamental to sustaining life, providing critical ecosystem services such as food provisioning, water purification, flood and drought control, nutrient cycling, and climate regulation, amongst many others. These services are essential to support human well-being and economic growth. Yet despite the significant economic, social and cultural values of biodiversity and ecosystem services, biodiversity worldwide is being lost, and in some areas at an accelerating rate.

  • The publications included in the review reported chemical analyses on 100 distinct foodstuffs and presented data on 455 nutrients and other substances. Statistical analysis by foodstuff was impractical given the large array of different foods (and cultivars/breeds) presented in included publications. The review team therefore decided to facilitate analysis and interpretation of the available information by categorising the nutrients and other substances reported into nutrient groups or “families”. ...

  • Orexin A and B (also known as hypocretins), two recently discovered neuropeptides, play an important role in food intake, sleep/wake cycle and neuroendocrine functions. Orexins are endogenous ligands of two G-protein-coupled receptors, termed OX1 and OX2. This work presents the first short orexin A and B analogues, orexin A 23–33 and orexin B 18–28, with high affinity (119 ± 49 and 49 ± 23 nM) for OX1 receptors expressed on SK-N-MC cells and indicates the importance of the C-terminal part of the orexin peptides for this ligand–receptor interaction.

  • The fact that the gut microfl ora can be altered for the benefi t of human health has motivated the development of new functional food ingredients. A probiotic is a live microbial food supplement, which benefi cially affects the host by improving its intestinal microbial bal- ance (Fuller 1989). A prebiotic is defi ned as a nondigestible food ingredient that benefi cially affects the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria in the colon, and thus improves host health (Gibson and Roberfroid 1995)....
