    Empathy for pain is referred to as an evolutionary behavior of social animals and humans associated with the ability to feel, recognize, understand and share the other's distressing (pain, social rejection and catastrophe) states. Impairment of ...
    Optical Stimulation and Electrophysiological Analysis of Regenerating Peripheral Axons
    Authors:  Patricia J. Ward and Arthur W. English, date: 06/20/2019, view: 132, Q&A: 0
    Although axons in the peripheral nervous system can regenerate, functional recovery after nerve injuries is poor. Activity-based therapies, such as exercise and electrical stimulation, enhance the regeneration of cut peripheral axons. Despite their ...
    A High-throughput qPCR-based Method to Genotype the SOD1G93A Mouse Model for Relative Copy Number
    Authors:  Valerie R. Tassinari and Fernando G. Vieira, date: 06/20/2019, view: 137, Q&A: 0
    [Abstract] The most commonly used mouse model in ALS preclinical research expresses multiple copies of the human SOD1 (G93A) transgene. During the course of breeding, successive generations of mice can lose copies of the transgene. Because shorter lifespan of these mice is dependent on transgene copy number, it is essential to ensure that no low-copy, and ...
    Production and Purification of Dengue Virus-like Particles from COS-1 Cells
    Authors:  Jedhan Ucat Galula, Gwong-Jen J. Chang and Day-Yu Chao, date: 06/20/2019, view: 142, Q&A: 0
    [Abstract] Non-infectious virus-like particles (VLPs) containing dengue virus (DENV) pre-membrane (prM) and envelope (E) proteins have been demonstrated to be highly immunogenic and can be used as a potential vaccine candidate as well as a tool for serodiagnostic assays. Successful application of VLPs requires abundant, and high-purity production methods. ...

    Authors:  Irena Misiewicz-Krzeminska, Isabel Isidro and Norma C. Gutiérrez, date: 06/20/2019, view: 789, Q&A: 0
    [Abstract] Protein analysis in bone marrow samples from patients with multiple myeloma (MM) has been limited by the low concentration of proteins obtained after CD138+ cell selection. A novel approach based on capillary nano-immunoassay could make it possible to quantify dozens of proteins from each CD138+ purified MM sample in an ...
    Determining Oxidative Damage by Lipid Peroxidation Assay in Rat Serum
    Authors:  Qian Tang, Yu-Wen Su and Cory J. Xian, date: 06/20/2019, view: 231, Q&A: 0
    [Abstract] It has been well-established that malondialdehyde (MDA), which is generated during the process of lipid peroxidation, is a commonly known biomarker for oxidative stress. Therefore, the serum levels of MDA are detected by using the lipid peroxidation assay with commercially available kit to determine the induction of oxidative stress in rat models.

    Authors:  Yang Yu, Chun-Li Li, Rui Du and Jun Chen, date: 06/20/2019, view: 180, Q&A: 0
    [Abstract] Empathy for pain is referred to as an evolutionary behavior of social animals and humans associated with the ability to feel, recognize, understand and share the other's distressing (pain, social rejection and catastrophe) states. Impairment of empathy can definitely lead to deficits in social communication and sociability (attachment, bond, ...
    Optical Stimulation and Electrophysiological Analysis of Regenerating Peripheral Axons

    Measurement of CD74 N-terminal Fragment Accumulation in Cells Treated with SPPL2a Inhibitor
    Authors:  Rubén Martínez-Barricarte, Xiao-Fei Kong and Jean-Laurent Casanova, date: 06/05/2019, view: 229, Q&A: 0
    [Abstract] The recent discovery of human signal peptide peptidase-like 2a (SPPL2a) deficiency in humans revealed the toxicity associated with the accumulation of one of its substrates, CD74 N-terminal fragment (CD74-NTF), for certain type of dendritic cells (cDC2). We developed a two-step protocol for monitoring the accumulation of this molecule in different ...
