Article Synopsis
  • Soluble CLEC-2 (sCLEC-2) is proposed as a potential biomarker for monitoring platelet activation using routine blood samples, with a newly developed rapid chemiluminescence enzyme immunoassay (CLEIA) that gives results in about 19 minutes.
  • The study evaluated the performance of the CLEIA method in terms of sensitivity, precision, and correlation with the established ELISA method, finding that it performed well and had similar reference ranges for healthy individuals.
  • Additionally, the research explored the different molecular forms of sCLEC-2 in patient samples, revealing that the CLEIA method primarily detects the shed form of sCLEC-2, suggesting its potential clinical relevance.

Article Synopsis
  • * The study found that sCLEC-2 levels were significantly elevated in patients with thrombotic or infectious diseases, especially in microvascular thrombosis (MVT), but the relationships between sCLEC-2, platelet count, and D-dimer were weak.
  • * ROC analysis indicates that combinations of sCLEC-2 with platelet count and D-dimer can effectively differentiate between thrombotic diseases like MVT and non-thrombotic conditions, making sCLEC-2 a

Introduction: Soluble C-type lectin-like receptor 2 (sCLEC-2) is a new biomarker for platelet activation, which can be easily measured by usual blood collection. We conducted the CLECSTRO, a prospective, observational cohort study, to evaluate the clinical implications of sCLEC-2 in patients with acute ischaemic stroke (AIS) and transient ischaemic attack (TIA).

Methods And Analysis: The participants are patients with AIS/TIA and control patients required for differentiation from AIS/TIA.

Unlabelled: The scoring systems for disseminated intravascular coagulation (DIC) criteria require several adequate cutoff values, vary, and are complicated. Accordingly, a simpler and quicker diagnostic method for DIC is needed. Under such circumstances, soluble C-type lectin-like receptor 2 (sCLEC-2) received attention as a biomarker for platelet activation.

Introduction: Podoplanin (PDPN) is known to induce platelet aggregation via interacting with the C-type lectin-like receptor-2 on platelets and is involved in postoperative venous thromboembolism (VTE) formation. In this study, we investigate the correlation between soluble C-type lectin-like receptor (sCLEC-2) levels and PDPN expression in patients with high grade gliomas and the relationship between sCLEC-2 levels and the occurrence of VTE.

Materials And Methods: Forty-four patients harboring high grade gliomas, treated surgically at the Department of Neurosurgery, Niigata University from April 2018 to August 2020, were included.

C-type lectin-like receptor 2 (CLEC-2) is a platelet-activated receptor expressed on the surface of platelet membranes. Soluble CLEC-2 (sCLEC-2) has been receiving attention as a predictive marker for thrombotic predisposition. The present study examined the relationship between sCLEC-2 level and degree of coagulation disorder in septic patients.

The aim of our study is to investigate the long-term transitions of intraocular pressure (IOP) and aqueous flare values in uveitis patients with faint anterior chamber flare who were treated with once-daily topical ophthalmic betamethasone for more than 6 months. The study included a total of 111 eyes of 68 outpatients. The mean follow-up period was 26.

Introduction: Corticosteroid therapy is a first-choice treatment for anti-aquaporin 4 antibody-positive neuromyelitis optica. Although we expected corticosteroid-induced glaucoma as a potential complication of the therapy, there are no reports in the literature describing it. In this report, we describe a case of successful trabeculotomy performed on a patient with corticosteroid-induced glaucoma and anti-aquaporin 4 antibody-positive neuromyelitis optica.

We determined pollen specific IgE in tears and compared these results to the concentration of specific IgE in serum samples. We obtained tears (using Schirmer strips) and serum samples from subjects with Japanese cedar (Cryptomeria japonica) pollinosis, and tested for C. japonica pollen specific IgE using a quantitative ELISA.

Entrapment neuropathies of the tibial nerve by Baker's cysts occur infrequently. We present a patient with entrapment neuropathy of the tibial nerve by a Baker's cyst which is preoperatively evaluated by nerve conduction study and magnetic resonance imaging. We present this case with a review of the literatures.

Purpose: We investigated the efficacy of the tear sampling method using a filter paper to evaluate eosinophil cationic protein (ECP) levels in patients with allergic disorders.

Methods: Subjects were an allergic group comprising patients with allergic conjunctivitis, vernal keratoconjunctivitis, or atopic keratoconjunctivitis, a Sjögren group comprising patients with secondary Sjögren syndrome, and a control group comprising healthy volunteers. Tears were sampled using the Schirmer Method I and the sample was eluted from the filter paper in 50 microL of elution solution containing phosphate buffer solution with 0.

We have developed a highly sensitive quantitative enzyme immunochromatography system for antigen-specific IgE, which is clinically important for the diagnosis of allergic diseases. The system uses alkaline phosphatase-labeled anti-IgE antibody (ALP-anti-IgE) and immobilized target antigen, for example cedar pollen antigen, on a membrane. Antigen-specific IgE present in the serum binds the immobilized antigen after complexing with the ALP-anti-IgE.

The aim of this study was to clarify the effects of anti-dsDNA antibodies on the titer and the nuclear staining pattern(s) in a fluorescent antinuclear antibody (FANA) assay using HEp-2 cells. Anti-dsDNA derived from 14 patients with systemic lupus erythematosus (SLE) was individually affinity-purified. The anti-dsDNA titer of the purified anti-dsDNA solution was measured by radioimmunoassay (RIA) or by enzyme-linked immunosorbent assay (ELISA).
