This paper extends the work on cross-layer design which combines adaptive modulation and coding at the physical layer and hybrid automatic repeat request protocol at the data link layer. By contrast with previous works on this topic, the present development and the performance analysis as well, is based on rate compatible punctured turbo codes. Rate compatibility provides incremental redundancy in transmission of parity bits for error correction at the data link layer. Turbo coding and iterative decoding gives lower packet error rate values in low signal-to-noise ratio regions of the adaptive modulation and coding (AMC) schemes. Thus, the applied cross-layer design results in AMC schemes can achieve better spectral efficiency than convolutional one while it retains the QoS requirements at the application layer. Numerical results in terms of spectral efficiency for both turbo and convolutional rate compatible punctured codes are presented. For a more comprehensive presentation, the performance of rate compatible LDPC is contrasted with turbo case as well as the performance complexity is discussed for each of the above codes.

This paper discusses recent research findings together with management schemes in preventing and managing of thermal stress by handling external and internal factors in livestock production systems. Preventive measures against thermal stress are described as basic structural adjustments and the modifications that can be implemented readily, according to animal health and welfare requirements and refer to （1） environmental modification and thermal comfort in various housing systems; （2） action on animals, such as genetic selection for breeds resistant to infectious disease, parasites and climate extremes; （3） action on feed and （4） action on staff handling the animals. Moreover, measures to be taken both in situations of chronic thermal stress and heat or cold strokes are presented as they are applied to （1） limit stress, （2） monitor the temperature felt by animals, （3） adapt diet and drinking water supplies and （4） correct physiological imbalances. Examples are given for different farm species （cattle, sheep, goat, poultry and pigs） and different production systems （intensive, extensive and alternative）. The paper concludes with a practical guide for the effective handling of thermal stress at farm level, summarizing the results from recent research studies on the specific topic.

Gastrointestinal stromal tumors (GISTs) are rare tumors, which represent approximately 1% of the neoplasms of the gastrointestinal tract. These tumors rarely give extra-abdominal metastases. However, their clinical outcome is potentially adverse. In some rare cases, co- existance of GISTs with other malignancies has been reported. Here we present a case of a 74-year old male with GIST, which was managed by surgical resection. Fourteen months later, the patient presented with liver metastases and imatinib mesylated was administered. During treatment, the patient reported skeletal pain and plane X-rays revealed osteolytic bone lesions. Further investigation revealed the presence of multiple myeloma. To the best of our knowledge, this is the first report of the co-existence of multiple myeloma (MM) with GIST.

在日粮中添加一定水平的豆油和鱼油混合物(SFO)是增加羊奶中脂肪酸(FA)生物活性的一个有效营养策略。研究旨在探讨在饲料中添加适量的SFO对奶的化学组成、FA含量以及血液中FA含量的影响。将奶山羊12只平均分成两组,对照组饲粮中不添加豆油和鱼油,试验组在饲粮中添加豆油55.5 g·d-1·只-1和鱼油11.1 g·d-1·只-1。研究表明,添加SFO对产奶量和乳脂率没有影响;与对照组相比,血液中trans-11 C18:2(VA)、cis-9、trans-11 C18:2共轭亚油酸(CLA)、trans-10、cis-12、C18 2 CLA、C20 5n-3(EPA)和C22:6n-3(DHA)显著提高(P<0.05),而C14 0、C15 0、C16 0和C18 0低于对照组。与对照组相比,在饲料中添加SFO可以增加VA、cis-9、trans-11 C18:2 CLA、trans-10、cis-12、C18 2 CLA、EPA、DHA、单不饱和脂肪酸(MUFA)、多不饱和脂肪酸(PUFA)和n-3 FA的含量,降低了短链脂肪酸、中链脂肪酸的含量、饱和与不饱和的比例及致动脉粥样硬化指数。在羊饲粮(在精料中混有适当草料)中添加SFO可以提高奶中FA的含量。
