A method for determining linezolid concentration in human serum using micellar electrokinetic capillary chromatography by direct injection of serum is described. A borate buffer (pH 8.0) containing sodium dodecyl sulfate was used as a run buffer and detection of linezolid was performed at 250 nm (its absorption maximum). The migration time of linezolid was 5.5 min and the detection limit was 0.5 mg/l (S/N = 3). The precision and accuracy of this method was good with no interference with the detection from bilirubin, hemoglobin and chyle of high concentrations. This provides a simple and easy method where samples of micro-quantity are used.

Background: Erectile dysfunction (ED) in men is overlooked and is often linked with psychogenic causes. Due to cultural barriers, this area of research remains neglected.
Objective: The study was conducted to determine the factors that can be associated with ED in otherwise apparently healthy men.

Introduction: Japanese encephalitis virus (JEV) and Zika virus (ZIKV) are prevalent in over 80 countries or territories worldwide, causing hundreds of thousands of cases annually. But currently there is a lack of specific antiviral agents and effective vaccines.
Methods: In the present study, to identify human neutralizing monoclonal antibody (mAb) against JEV or/and ZIKV, we isolated ZIKV-E protein-binding B cells from the peripheral venous blood of a healthy volunteer who had received the JEV live-attenuated vaccine and performed 10× Genomics transcriptome sequencing and BCR sequencing analysis, we then obtained the V region amino acid sequences of a novel mAb LZY3412.

Spontaneous tumor regression is a recognized phenomenon across various cancer types. Recent research emphasizes the alterations in autoantibodies against carbonic anhydrase I (CA I) (anti-CA I) levels as potential prognostic markers for various malignancies. Particularly, autoantibodies targeting CA I and II appear to induce cellular damage by inhibiting their respective protein's catalytic functions.

Primary immunodeficiency (PID) is one of the causes of secondary autoimmune hemolytic anemia (AIHA) and Evans' syndrome (ES). Serum immunoglobulins should be tested in patients with AIHA/ES, as common variable immunodeficiency is the most common PID of secondary AIHA/ES. However, it is not fully understood how immunodeficiency is assessed, in addition to serum immunoglobulins.
