    Testing for Assortative Mating by Diet in Drosophila melanogaster
    Authors:  Philip T Leftwich and Tracey Chapman, date: 10/20/2018, view: 20, Q&A: 0
    Experimental studies of the evolution of reproductive isolation in real time are a powerful way to reveal the way that fundamental processes, such as mate choice, initiate divergence. Mate choice, while frequently described in females, can occur in ...
    Optical Clearing and Index Matching of Tissue Samples for High-resolution Fluorescence Imaging Using SeeDB2
    Authors:  Meng-Tsen Ke and Takeshi Imai, date: 10/20/2018, view: 27, Q&A: 0
    Tissue clearing techniques are useful for large-scale three-dimensional fluorescence imaging of thick tissues. However, high-resolution imaging deep inside tissues has been challenging, as it is extremely sensitive to light scattering and spherical ...
    Behavioral Evaluation of Seeking and Preference of Alcohol in Mice Subjected to Stress
    Authors:  Ana Canseco-Alba, Norman Schanz, Hiroki Ishiguro, Qing-Rong Liu and Emmanuel S. Onaivi, date: 10/20/2018, view: 18, Q&A: 0
    The alcohol preference model is one of the most widely used animal models relevant to alcoholism. Stressors increase alcohol consumption. Here we present a protocol for a rapid and useful tool to test alcohol preference and stress-induced alcohol ...
    Testing for Assortative Mating by Diet in Drosophila melanogaster
    Authors:  Philip T Leftwich and Tracey Chapman, date: 10/20/2018, view: 20, Q&A: 0
    [Abstract] Experimental studies of the evolution of reproductive isolation in real time are a powerful way to reveal the way that fundamental processes, such as mate choice, initiate divergence. Mate choice, while frequently described in females, can occur in either sex, and can be affected by the genetics or environment of an individual. Here we describe ...
    Optical Clearing and Index Matching of Tissue Samples for High-resolution Fluorescence Imaging Using SeeDB2
    Authors:  Meng-Tsen Ke and Takeshi Imai, date: 10/20/2018, view: 27, Q&A: 0
    [Abstract] Tissue clearing techniques are useful for large-scale three-dimensional fluorescence imaging of thick tissues. However, high-resolution imaging deep inside tissues has been challenging, as it is extremely sensitive to light scattering and spherical aberrations. Here, we present a water-based optical clearing and mounting media, SeeDB2, which is ...
    Behavioral Evaluation of Seeking and Preference of Alcohol in Mice Subjected to Stress
    Authors:  Ana Canseco-Alba, Norman Schanz, Hiroki Ishiguro, Qing-Rong Liu and Emmanuel S. Onaivi, date: 10/20/2018, view: 18, Q&A: 0
    [Abstract] The alcohol preference model is one of the most widely used animal models relevant to alcoholism. Stressors increase alcohol consumption. Here we present a protocol for a rapid and useful tool to test alcohol preference and stress-induced alcohol consumption in mice. In this model, animals are given two bottles, one with a diluted solution of ...
    Drosophila Endurance Training and Assessment of Its Effects on Systemic Adaptations
    Authors:  Deena Damschroder , Tyler Cobb, Alyson Sujkowski and Robert Wessells, date: 10/05/2018, view: 131, Q&A: 0
    [Abstract] Exercise induces beneficial systemic adaptations that reduce the incidence of age-related diseases. However, the molecular pathways that elicit these adaptations are not well understood. Understanding the molecular mechanisms that underlie the exercise response can lead to widely beneficial therapies. Large populations, relatively short lifespan, ...
    Measurement of Dopamine Using Fast Scan Cyclic Voltammetry in Rodent Brain Slices
    Authors:  Madelyn I. Mauterer, Paige M. Estave, Katherine M. Holleran and Sara R. Jones, date: 10/05/2018, view: 104, Q&A: 0
    [Abstract] Fast scan cyclic voltammetry (FSCV) is an electrochemical technique that allows sub-second detection of oxidizable chemical species, including monoamine neurotransmitters such as dopamine, norepinephrine, and serotonin. This technique has been used to record the physiological dynamics of these neurotransmitters in brain tissue, including their ...
    Isolation of Chromatin-bound Proteins from Subcellular Fractions for Biochemical Analysis
    Author:  Sébastien Gillotin, date: 10/05/2018, view: 134, Q&A: 0
    [Abstract] Shuttling of proteins between different cellular compartments controls their proteostasis and can contribute in some cases to regulate their activity. Biochemical analysis of chromatin-bound proteins, such as transcription factors, is often difficult because of their low yield and due to the interference from nucleic acids. This protocol describes ...
    Behavioral Evaluation of Odor Memory in Mice
    Authors:  Afif J. Aqrabawi and Jun Chul Kim, date: 09/20/2018, view: 187, Q&A: 0
    [Abstract] Behavioural tests based on the spontaneous recognition paradigm have been used extensively for examining the memory capacity of rodents. By exploiting their innate preference to investigate novel stimuli, inferences can be drawn about the perceived familiarity of encountered objects. Olfaction is the dominant sense used by mice to navigate their ...
    6-hydroxydopamine (6-OHDA) Oxidative Stress Assay for Observing Dopaminergic Neuron Loss in Caenorhabditis elegans
    Authors:  Sarah-Lena Offenburger and Anton Gartner, date: 09/20/2018, view: 206, Q&A: 0
    [Abstract] The nematode Caenorhabditis elegans is a powerful genetic model that can be used to investigate neuronal death. Research using C. elegans has been crucial to characterize cell death programmes that are conserved in mammals. Many neuronal signaling components, such as those mediating dopaminergic neurotransmission, are preserved ...
    Artificial Inhalation Protocol in Adult Mice
    Authors:  Thomas P. Eiting and Matt Wachowiak, date: 09/20/2018, view: 204, Q&A: 0
    [Abstract] Research in the area of in vivo olfactory physiology benefits from having direct access to the nasal airways through which odorants can be presented. Ordinarily, the passage of odorants through the airways is controlled by respiratory rhythm. This fact makes it difficult to control the timing and strength of an olfactory stimulus, since ...
    Assessing Classical Olfactory Fear Conditioning by Behavioral Freezing in Mice
    Authors:  Jordan M. Ross and Max L. Fletcher, date: 09/20/2018, view: 191, Q&A: 0
    [Abstract] Classical fear conditioning typically involves pairing a discrete cue with a foot shock. Quantifying behavioral freezing to the learned cue is a crucial assay for neuroscience studies focused on learning and memory. Many paradigms utilize discrete stimuli such as tones; however, given mice are odor-driven animals and the wide variety of odorants ...
