Radiation therapy is an important treatment modality for abdominal or pelvic cancer, but there a common and serious complication such as radiation-induced enteritis. Probiotics reported to have positive effects against enteropathy. In this study, morphological changes of bowel mucosa were analyzed in rats presume the effect probiotics on enteritis its correlation with radiation dose. A total 48 adult male Sprague-Dawley randomly assigned two groups received solution containing 1.0×10(8)...
Vasoactive intestinal peptide (VIP) signaling via cyclic adenosine monophosphate (cAMP) is reported to stimulate steroidogenesis in ovarian granulosa cells from a variety of vertebrate species, including the domestic hen. Prior follicle selection hen ovary (i.e., recruitment) follicle-stimulating-hormone (FSH)-induced cAMP absent within layer until immediately following selection. As consequence, remain an undifferentiated state and are unable initiate FSH-induced steroidogenesis. VIP...
Large gulls are generalist predators that play an important role in Arctic food webs. Describing the migratory patterns and phenology of these is essential to understanding how ecosystems function. However, from all six large gull taxa, including three long-distance migrants, date seasonal movements have been studied only with small sample sizes. To document flyways behaviour Vega gull, a widespread but little-studied Siberian migrant, we monitored 28 individuals GPS loggers over mean period...
Lipid profiles in wheat leaves and the effects of tan spot on were quantified by mass spectrometry. Inoculation with Pyrenophora tritici-repentis significantly reduced amount leaf lipids, including major plastidic lipids monogalactosyldiacylglycerol (MGDG) digalactosyldiacylglycerol (DGDG), which together accounted for 89% spectral signal detected leaves. Levels these susceptible cultivars dropped much more quickly during infection than those resistant cultivars. Furthermore, or to displayed...
Honey bee reproductive behavior involves a complicated mating system that embodies number of factors, including environmental and human-induced factors. Controlled breeding in isolated stations is prerequisite to maintain the genetic resources honey bees through natural mating. The concept controlled challenge most beekeeping operations due its low success rate. Therefore, detailed investigation into suitability interest. Thus, we bred two subspecies (Apis cerana koreana Apis mellifera L.)...
Purpose: The overall goal of this study is to restore kilovoltage computed tomography (kV‐CT) images which are disfigured by patients’ metal prostheses. By generating a hybrid sinogram that combination kV and megavoltage (MV) projection data, the authors suggest novel artifact‐reduction (MAR) method retains image quality match kV‐CT simultaneously restores information prostheses lost due photon starvation. Methods: CT data contain about attenuation coefficients total length attenuation....
다양한 생리활성을 함유한 보리잎을 이용하여 관능적으로 우수한 보리잎 분말차를 제조하는 방법을 개발하고 분말차의 기능성 성분함량을 분석하였다. 실험조건으로 보리잎차를 제조한 후 제조조건을 선발하였다. 그 결과 공정은 절단, 세척하는 전처리 공정, 100℃에서 30초간 가열하는 증열공정, 130℃에서 40분간 처리하는 조유공정, 실온에서 25분간 유념공정, 60℃로 30분간 덖음하는 중유공정, 55℃에서 재덖음하는 정유공정, 20분간 건조하는 건조공정, 85℃에서 회전 가향공정 및 분쇄공정으로 최적화되었다. 이상의 방법으로 제조된 분말차는 식이섬유 33.8%, 아미노산 12.9%, 무기질 4.7%, β-carotene 6.9 ㎎% 등이 함유되어 있었다.
Honeybees pollinate over 75% of the total food resources produced annually, and they produce valuable hive products, such as bee pollen, propolis, royal jelly. However, species Asian hornet (Vespa velutina) feed on more than 85% honeybees, causing a decline in their population considerable damage to beekeepers Korea. To prevent portable real-time monitoring system was developed that detects V. velutina individuals notifies users presence. This designed with focus portability ease...
To investigate the acaricide toxicity and resistance mechanisms in Varroa mite, it is essential to understand genetic responses of mites acaricides, which are usually evaluated by transcriptional profiling based on quantitative real-time polymerase chain reaction (qPCR). In this study, select reference genes showing consistent expression patterns regardless treatment or type tissue, treated with each three representative acaricides (coumaphos, fluvalinate, amitraz) were processed for...
석회유황합제의 엽상잔류 독성평가는 양봉꿀벌과 서양뒤영벌에 안전한 것으로 나타났다. Carbaryl의 양봉꿀벌에 독성은 매우 높은 나타났으며, carbaryl 처리후 21일까지 노출 처리구에서 대부분 70%이상 사망률이 따라서 메밀 잎에서 대한 carbaryl의 잔류독성은 장기간 메밀에서 처리에 엽상잔류량 평가는 살포후 1일에는 180ppm, 10일에는 110ppm, 18일에는 18.6ppm으로 반감기는 9일로 평가되었다. 잔류 독성 안전 기준은 살포 후 22일 이상, 엽상잔류량은 10ppm 이하로 제시되었다.
An experimental study on the automation of coffee roasting process was conducted. For this study, a temperature sensor, controllers, and motors were added to manually operated roaster. The temperature, time, exhausting damper control selected as parameters. thermocouple measurements severely influenced by size location As result, standard roaster experimentally set show similar trend change using previously installed thermometer. A chosen through repeated experiments advice expert....
월동 전 꿀벌응애 감염 정도에 따른 양봉꿀벌 봉군 성공률과 중 발생하는 사충수를 분석한 결과 10% 이상 그룹에서 가장 높은 사충수가 확인되었다. 또한, 성공률이 20%로 낮았으며, 세력도 그룹이 낮았다. 대조구와 5% 미만 그룹은 모든 변수에서 차이가 나타나지 않았다. 최종적으로 검출수가 높을수록 증가하는 경향이 있었다. 본 연구의 결과로 양봉꿀벌의 성공적인 월동을 위해 최소 밀도 조절량에 대한 기초 정보로 사용할 수 있을 것으로 사료된다.
The ectoparasitic mite Varroa destructor is well known for transmitting a number of viruses that can contribute to the collapse honeybee colonies. To date, many control measures put in place limit spread V. have yielded no satisfactory results. This challenging because effect parasite on colonies becoming notorious. has weakened beekeeping industry and reduced pollination services, which may global food insecurity future. Therefore, it necessary possible outline sustainable approaches...
