Aggression is a common behavioral trait shared in many animals, including both vertebrates and invertebrates. However, the type and intensity of agonistic encounters and displays can vary widely both across and within species, resulting in complicated or subjective interpretations that create difficulties in developing theoretical models that can be widely applied. The need to easily and objectively identify quantifiable behaviors and their associated morphologies becomes especially important when attempting to decipher the neurological mechanisms underlying this complex behavior. Monoamines, neuropeptides, and pheromones have been implicated as important neuromodulators for agonistic displays in both invertebrates and vertebrates. Ad- ditionally, recent breakthroughs in insect research have revealed exciting proximate mechanisms important in aggression that may be broadly relevant, due to the relatively high conservation of these neurochemical systems across animal taxa. In this review, we present the latest research demonstrating the importance of monoamines, neuropeptides, and pheromones as neuromodulators for aggression across a variety of insect species. Additionally, we describe the stalk-eyed fly as a model system for studying aggres- sion, which integrates physiological, morphological, and neurochemical approaches in exploring detailed mechanisms responsible for this common yet complex behavior. We conclude with our perspective on the most promising lines of future research aimed at understanding the proximate and ultimate mechanisms underlying aggressive behaviors .

Measuring and Forecasting Chinese Domestic Supply and Demand for Grain Sorghum

引用

Agricultural Sciences 2020年第1期11卷 71-87页

作者： Shuguo Yang jaime Malaga College of Economics & Management Heilongjiang Bayi Agricultural University Daqing China Department of Agricultural and Applied Economics Texas Tech University Lubbock Texas

In the past 5 years, the use of sorghum as substitutes for corn for feed in China has increased rapidly. Most of the recent growth of demand in sorghum has mainly been met by imported sorghum. Because sorghum is a minor crop and only shares a very small proportion of the grain production in China, few studies have examined domestic demand and supply of sorghum in China. Both China’s producers and other sorghum import countries can benefit from forecasts of China’s domestic supply and demand for sorghum.

Thiol-Mediated Reduction of <i>Staphylococcus aureus</i>Tellurite Resistance

引用

Advances in Microbiology 2014年第4期4卷 183-190页

作者： Benoit Pugin Fabián A. Cornejo jaime A. garcía Waldo A. Díaz-Vásquez Felipe A. Arenas Claudio C. Vásquez Departamento de Biología Facultad de Química y Biología Universidad de Santiago de Chile Santiago Chile Departamento de Biología Facultad de Química y Biología Universidad de Santiago de Chile Santiago Chile Facultad de Ciencia Universidad San Sebastián Santiago Chile

The goal of this work was to enhance tellurite toxicity against Gram positive bacteria, especially Staphyloccocus aureus. Using a combination of assays (growth inhibition zones, growth curves, and minimal inhibitory concentrations), tellurite toxicity against this bacterium was tested in the presence of various SH- and OH-containing compounds. Results showed that the noxiousness of tellurite was strongly enhanced in the presence of 2-mercaptoethanol or dithiothreitol. The potentiating effect was observed in S. aureus ATCC 6538 (the model organism of this study) and in other Gram positive bacteria such as Bacillus subtillis ATCC 6051 and the methicillin-resistant S. aureus strain 622-4. No enhancing effect was observed in Gram negative bacteria such as Escherichia coli BW25113, Salmonella Typhimurium LT2 and Klebsiella pneumoniae ATCC 11388. These results open new perspectives for studying the treatment of multidrug-resistant Gram positive bacteria, which are responsible for numerous nosocomial infections.

Virologica Sinica 2014年第4期29卷 242-249页

作者： Luisa Fernanda Mancipe Jiménez Gloria Ramírez Nieto Victor Vera Alfonso Jairo jaime Correa Laboratory of Animal Virology Faculty of Veterinary Medicine and Animal Science National University of Colombia

Porcine respiratory disease complex （PRDC） is a serious health problem that mainly affects growing and finishing pigs. PRDC is caused by a combination of viral and bacterial agents, such as porcine reproductive and respiratory syndrome virus （PRRSV）, swine influenza virus （SIV）, Mycoplasma hyopneumoniae （Myh）, Actinobacillus pleuropneumoniae （APP）, Pasteurella multocida and Porcine circovirus 2 （PCV2）. To characterize the specific role of swine influenza virus in PRDC presentation in Colombia, 11 farms from three major production regions in Colombia were examined in this study. Nasal swabs, bronchial lavage and lung tissue samples were obtained from animals displaying symptoms compatible with SIV. Isolation of SIV was performed in 9-day embryonated chicken eggs or Madin-Darby Canine Kidney （MDCK） cells. Positive isolates, identified via the hemagglutination inhibition test, were further analyzed using PCR. Overall, 7 of the 11 farms were positive for SIV. Notably, sequencing of the gene encoding the hemagglutinin （HA） protein led to grouping of strains into circulating viruses identified during the human outbreak of 2009, classified as pandemic H1N1-2009. Serum samples from 198 gilts and multiparous sows between 2008 and 2009 were obtained to determine antibody presence of APP, Myh, PCV2 and PRRSV in both SIV-H1Nlp-negative and -positive farms, but higher levels were recorded for SIV- HI Nlp-positive farms. Odds ratio （OR） and P values revealed statistically significant differences （p〈0.05） in PRDC presentation in gilts and multiparous sows of farms positive for SIV-HINlp. Our findings indicate that positive farms have increased risk of PRDC presentation, in particular, PCV2, APP and Myh.

Military Medical Research 2021年第1期8卷 103-115页

作者： jaime K.Devine Jake Choynowski Tina Burke Kajsa Carlsson Vincent F.Capaldi Ashlee B.McKeon Walter J.Sowden Operational Fatigue and Performance Institutes for Behavior ResourcesBaltimoreMD 21218USA Behavioral Biology Branch Walter Reed Army Institute of Research503 Robert Grant AveSilver SpringMD 20910USA Tripler Army Medical Center HonoluluHI 96859USA

Background: The Walter Reed Army Institute of Research(WRAIR) Operational Research Kit-Actigraphy(WORK-A) is a set of unique practice parameters and actigraphy-derived measures for the analysis of operational military sleep patterns. The WORK-A draws on best practices from the literature and comprises 15 additional descriptive variables. Here, we demonstrate the WORK-A with a sample of United States Army Reserve Officers’ Training Corps(ROTC) cadets(n=286) during a month-long capstone pre-commissioning training ***: The sleep of ROTC cadets(n=286) was measured by Philips Actiwatch devices during the 31-day training exercise. The preliminary effectiveness of the WORK-A was tested by comparing differences in sleep measures collected by Actiwatches as calculated by Philips Actiware software against WORK-A-determined sleep measures and self-report sleep collected from a subset of ROTC cadets(n=140).Results: Actiware sleep summary statistics were significantly different from WORK-A measures and self-report sleep(P≤0.001). Bedtimes and waketimes as determined by WORK-A major sleep intervals showed the best agreement with self-report bedtime(22:21±1:30 vs. 22:13±0:40, P=0.21) and waketime(04:30±2:17 vs. 04:31±0:47, P=0.68). Though still significantly different, the discrepancy was smaller between the WORK-A measure of time in bed(TIB) for major sleep intervals(352±29) min and self-report nightly sleep duration [(337±57) min, P=0.006] than that between the WORK-A major TIB and Actiware TIB [(177±42) min, P≤0.001].Conclusions: Default actigraphy methods are not the most accurate methods for characterizing soldier sleep, but reliable methods for characterizing operational sleep patterns is a necessary first step in developing strategies to improve soldier readiness. The WORK-A addresses this knowledge gap by providing practice parameters and a robust variety of measures with which to profile sleep behavior in service members.

Acclimatization of in Vitro-derived Dendrobium

Horticultural Plant Journal 2017年第3期3卷 110-124页

作者： jaime A.Teixeira da Silva Mohammad Musharof Hossain Madhu Sharma Judit Dobránszki Jean Carlos Cardoso ZENG Songjun Miki-cho post office Department of Botany University of Chittagong Division of Biotechnology CSIR-Institute of Himalayan Bioresource Technology Research Institute of Nyíregyháza University of Debrecen Centro de Ciências Agrárias UFSCar Guangdong Provincial Key Laboratory of Applied Botany South China Botanical GardenChinese Academy of Sciences

The successful ex vitro establishment of Dendrobium plantlets raised in vitro determines the quality of the end product(cut flowers or potted plants) in commercial production for economic gain. When in vitro Dendrobium plantlets are transplanted from the culture room to greenhouse conditions, they may desiccate or wilt rapidly and can die as a result of changes in the environment, unless substantial precautions are taken to adapt plantlets to a new environment. The acclimatization of in vitro-grown Dendrobium plantlets to an ex vitro environment by gradually weaning them towards ambient relative humidity and light levels facilitates better survival of young and physiologically sensitive *** plantlets raised in vitro must thus undergo a period of acclimatization or transitional development to correct anatomical abnormalities and to enhance their physiological performance to ensure survival under ex vitro conditions. The most common approach to improve the survival of Dendrobium plantlets upon transfer to an ex vitro environment is their gradual adaptation to that environment. Under such conditions, plants convert rapidly from a heterotrophic or photomixotrophic state to an autotrophic growth, develop a fully functional root system,and better control their stomatal and cuticular transpiration. Gradual adaptation is carried out in a greenhouse by decreasing relative humidity using fog or mist chambers and by increasing light intensity using shading techniques. This review details the acclimatization and ex vitro survival of Dendrobium plants produced in vitro. This advice is also useful for other orchids.
