摘要： The article offers information on the Ninth International Workshop on the Biology of Lactation in Farm Animals and Triennial Lactation Symposium held in Indianapolis, Indiana on July 11, 2008. It discusses the presentations related to immune function of the mammary gland. It mentions the research on additional value of milk through targeted manipulation of the content of immunomodulators to benefit human and animal health.

关键词： adipocyte   meat animal   preadipocyte   review  

摘要： The quality and value of the carcass in domestic meat animals are reflected in its protein and fat content. Preadipocytes and adipocytes are important in establishing the overall fatness of a carcass, as well as being the main contributors to the marbling component needed for consumer preference of meat products. Although some fat accumulation is essential, any excess fat that is deposited into adipose depots other than the marbling fraction is energetically unfavorable and reduces efficiency of production. Hence, this review is focused on current knowledge about the biology and regulation of the important cells of adipose tissue: preadipocytes and adipocytes.

摘要： 分子生物学技术的迅速发展对动物营养学产生了深远的影响,使动物营养学家能够以更高的精度和灵敏度来深入探索许多复杂的问题,如饲料营养成分分析、各种家畜饲养标准的制定、营养不足或缺乏对动物生长、繁殖、生产及免疫的影响等。分子生物学在动物营养上的应用为生产实践提供了科学依据。

关键词： Ischyrocerus anguipes   Association   Paralithodes camtschaticus   Barents Sea   Biology features  

摘要： This paper describes size composition, morphometric, and reproductive parameters of the summer generation of the amphipod Ischyrocerus anguipes (KrCyer, 1838) associated with the red king crab Paralithodes camtschaticus (Tilesius, 1815) in Dalnezelenetskaya Bay (southern Barents Sea, Russia). In summer 2004-2007, prevalence and mean number of I. anguipes per host were 15.0% and 6.9 +/- A 1.1 specimens, respectively. The majority of amphipods were found on the host carapace (47.4%) and the limbs (43.9%). High infestation indices and absence of negative impacts for the host indicate that I. anguipes is a facultative commensal of the red king crab. The amphipods sex ratio was significantly biased toward females (F:M = 2:1). Females had a greater size than males. The size at 50% maturity of I. anguipes females was estimated to be 3.37 mm. The number of eggs laid is linearly correlated with the size of a female. Some differences in biological features of symbiotic and free-living amphipods (data obtained in 1940-1950) may be explained by climatic changes in the Barents Sea or advantages of living on the crab.

摘要： A good understanding of telomeres and telomerase biology is crucial for unraveling mechanisms related to aging and cancer. However, in vivo vertebrate studies of telomere biogenesis and telomerase function have been limited by the development of appropriate animal model systems. The present study aims to demonstrate evolutionary conservation of telomerase in vertebrate species, supporting the potential application of fish as vertebrate model for studying telomeres and telomerase function. Comparison of genomic and protein information among vertebrate TERTs (TElomerase Reverse Transcriptase), the Japanese medaka Oryzias latipes shares the highest similarity to that of the human than the other small size fish species studied (including pufferfish and zebrafish). The ubiquitous expression of TERT mRNA, the high constitutive level of telomerase activity, and the humanized telomere lengths further substantiate that Japanese medaka is an ideal vertebrate model for the study of telomere and telomerase-related mechanisms in vivo. Moreover, medaka exhibits fast, invariable growth and is able to provide a variety of useful developmental and reproductive endpoints for lifelong and multi-generational experiments. Our earlier and present findings support the use of medaka for studying organismal aging, tissue regeneration and carcinogenesis. (C) 2008 Elsevier Inc. All rights reserved.

摘要： The Asian plant bug Stethoconus praefectus (Distant) (Heteroptera: Miridae) was recently discovered in Florida preying on the avocado lace bug, Pseudacysta perseae (Heidemann) (Heteroptera: Tingidae). Its life cycle and effectiveness as a predator of R perseae were investigated at 26 +/- 1 degrees C, 60 +/- 5 RH, and 12: 12 (L: D) under laboratory conditions. Stethoconus praefectus developed from egg to adult in 16.5 +/- 0.2 d. On average, the first 4 instars consumed 2 to 4 prey per day, whereas the last 2 instars consumed 2 to 7 lace bugs per day. Stethoconus praefectus was observed in the field from Aug through Dec 2007.
