Dioscin Mediated IgA Nephropathy Alleviation by Inhibiting B Cell Activation In Vivo and Decreasing Galactose-Deficient IgA1 Production In Vitro14:18

Dioscin Mediated IgA Nephropathy Alleviation by Inhibiting B Cell Activation In Vivo and Decreasing Galactose-Deficient IgA1 Production In Vitro

This study provides experimental data for treating immunoglobulin A nephropathy (IgAN) with Dioscin (DIO), the active ingredient of Dioscoreae Nipponicae Rhizoma (DNR), and a paradigm for studying herbal medicine's effects and underlying mechanisms in vivo and in...

RNA Interference in Ticks09:06

RNA Interference in Ticks

A method for RNA interference (RNAi) by injection of dsRNA into unfed ticks is described. RNAi is the most widely used gene-silencing technique in ticks where the use of other methods of genetic manipulation has been limited.

Detection of True IgE-expressing Mouse B Lineage Cells09:40

Detection of True IgE-expressing Mouse B Lineage Cells

In vitro analysis of class switch recombination in mice is challenging due to cytophilic IgE molecules bound to Fc receptors on the surface of B cells. We describe a method for IgE detection using trypsin-mediated cleavage of surface-bound IgE prior to fixation and permeabilization for cytoplasmic fluorescence...

Isolation of microRNAs from Tick Ex Vivo Salivary Gland Cultures and Extracellular Vesicles08:03

Isolation of microRNAs from Tick Ex Vivo Salivary Gland Cultures and Extracellular Vesicles

The present protocol describes the isolation of microRNAs from tick salivary glands and purified extracellular vesicles. This is a universal procedure that combines commonly used reagents and supplies. The method also allows the use of a small number of ticks, resulting in quality microRNAs that can be readily sequenced.

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance01:14

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance

Avoidance-avoidance conflict refers to a psychological situation where a person must choose between two or more unpleasant alternatives. These conflicts are particularly stressful because neither option is desirable. This dilemma is often expressed in sayings like "caught between a rock and a hard place" or "between the devil and the deep blue sea." For instance, individuals who fear dental procedures may find themselves torn between enduring a painful toothache or facing the...
