To simplify the serotyping of Streptococcus pneumoniae, a dot bot assay has been developed and compared with the standard quellung reaction in 1,082 isolates. The technique has been demonstrated to be sensitive, specific, easy to perform, and inexpensive. The dot blot assay could be useful when large numbers of pneumococci have to be studied.

Ventricular arrhythmias induced by ischemia/reperfusion injury limits the therapeutic effect of early reperfusion therapy for acute myocardial infarction. This study investigated the protective effects of the β2-adrenergic receptor (β2-AR) agonist clenbuterol against ischemia/reperfusion-induced arrhythmias and the underlying mechanism. Anesthetized rats were subjected to 10-min left coronary artery occlusion and 10-min reperfusion in vivo.

Purpose: This study aimed to investigate the role of SIRT4 in retinal protection, specifically its ability to mitigate excitotoxic damage to Müller glial cells through the regulation of mitochondrial dynamics and glutamate transporters (GLASTs).
Methods: A model of retinal excitatory neurotoxicity was established in mice. Proteins related to mitochondrial dynamics, GLAST, and SIRT4 were analyzed on days 0, 1, 3, and 5 following toxic injury.

Purpose: To investigate the effect of Ca2+/calmodulin-dependent protein kinase II (CAMKII) δ subtypes (CAMK2D) on sodium iodate (NaIO3)-induced retinal degeneration in mice.
Methods: Bioinformatics analysis and Western blot experiments were used to screen the significantly differentially expressed genes in age-related macular degeneration (AMD) disease. CAMK2D knockdown and overexpression models were constructed by lentivirus (LV) infection of adult retinal pigment epithelial cell line-19 (ARPE-19) cells in vitro.

Background: Autoimmune bullous disorder (AIBD) is a diverse group of blistering dermatoses that affects the skin and mucous membrane, characterized by the formation of autoantibodies against the desmosomal glycoproteins and adhesion molecular components of the basement membrane zone. Various immunoassay techniques for serological diagnosis are Direct Immunofluorescence (DIF), Indirect Immunofluorescence (IIF), Enzyme Linked Immunosorbent Assay (ELISA) and immunoblotting. Quantitative ELISA titer can also be used to monitor the disease activity and response to treatment.

Hutchinson-Gilford progeria syndrome (HGPS) is a premature aging disease caused by progerin, a mutant variant of lamin A. Progerin anchors aberrantly to the nuclear envelope disrupting a plethora of cellular processes, which in turn elicits senescence. We previously showed that the chromosomal region maintenance 1 (CRM1)-driven nuclear export pathway is abnormally enhanced in patient-derived fibroblasts, due to overexpression of CRM1.
