先价格后配置2006年笔记本低价难免

“年年岁岁花相似,岁岁年年笔不同!”天气开始逐渐暖和起来,又一年的春天已经来临,春风拂面,扬柳青青,灿烂阳光下盛开的花朵年年岁岁般的美丽,好像没有大的变化,但对于笔记本市场而言和去年此时比起来却发生了巨大的变化。又是一个辞旧迎新的季节,随着Napa的闹春,Sonoma则慢慢让出主流市场,而对于第一代迅驰移动技术平台——Carmel的名字似乎已经渐渐被人们所遗忘。各大笔记本生产厂家在刚刚进入2006便开始了大批量的降价活动,而对于二线三线厂商而言也只好频频降价促销。随着笔记本电脑价格的进一步下降,中低端市场越来越发耀眼,其高销售…

A review of the growth, and of the carcass and meat quality characteristics of the one-humped camel (Camelus dromedaries)

The dromedary camel is a good source of meat especially in areas where the climate adversely affects the performance of other meat animals. This is because of its unique physiological characteristics, including a great tolerance to high temperatures, solar radiation, water scarcity, rough topography and poor vegetation. The average birth weight of camels is about 35kg, but it varies widely between regions, breeds and within the same breed. The meat producing ability of camels is limited by modest growth rates (500g/day). However, camels are mostly produced under traditional extensive systems on poor levels of nutrition and are mostly slaughtered at older ages after a career in work, racing or milk production. Camels reach live weights of about 650kg at 7-8 years of age, and produce carcass weights ranging from 125 to 400kg with dressing-out percentage values from 55% to 70%. Camel carcasses contain about 57% muscle, 26% bone and 17% fat with fore halves (cranial to rib 13) significantly heavier than the hind halves. Camel lean meat contains about 78% water, 19% protein, 3% fat, and 1.2% ash with a small amount of intramuscular fat, which renders it a healthy food for humans. Camel meat has been described as raspberry red to dark brown in colour and the fat of the camel meat is white. Camel meat is similar in taste and texture to beef. The amino acid and mineral contents of camel meat are often higher than beef, probably due to lower intramuscular fat levels. Recently, camel meat has been processed into burgers, patties, sausages and shawarma to add value. Future research efforts need to focus on exploiting the potential of the camel as a source of meat through multidisplinary research into efficient production systems, and improved meat technology and marketing.     

Procyanidin effects on oesophageal adenocarcinoma cells strongly depend on flavan-3-ol degree of polymerization

Epidemiological studies have shown that the risk of developing oesophageal adenocarcinoma (OA) is inversely correlated to consumption of fruits and vegetables. Flavan-3-ols are the most abundant subclass of flavonoids in these types of foods. Three apple-derived procyanidin fractions with different average degrees of polymerization (aDP) were characterized and the effects of these fractions and of pure flavan-3-ol monomers ((-)-epicatechin and (+)-catechin) and dimers (B1, B2) on two OA cell lines were investigated. Flavan-3-ol monomers and dimers had no effect on the two cell lines, while apple-derived flavan-3-ol oligomers and polymers induced a time-dependent reduction of cell viability. The reduction in the cell viability was due to the induction of caspase-mediated apoptosis and an arrest of the cell cycle in G0/G1. The magnitude of the reduction in cell viability and induction of apoptosis after exposure to flavan-3-ol oligomeric/polymeric fractions positively correlated with their aDP. These results indicate that only flavan-3-ol oligomers and polymers, but not monomers and dimers, have an effect on the proliferation of OA cells in vitro. As tested flavan-3-ol concentrations are achievable through diet, this study suggests that apple-derived PA may possess chemotherapeutic effects against OA.
