Low-temperature cryopreservation is a common method for scientific research and clinical sample preservation when utilizing flow cytometry. In flow cytometry data analysis, traditional manual "gating" is susceptible to past experience and faces the challenge of manual subjective bias, time-consuming, and multidimensional data analysis. With the development of algorithms, the advantages of dimensionality reduction and clustering in result analysis are gradually becoming more prominent.

To establish a dual immunoassay based on inductively coupled plasma mass spectrometry (ICP-MS) with stable element labeling antibodies for the simultaneous detection of alpha-fetoprotein (AFP) and prostate-specific antigen (PSA) in serum and evaluate its performance and clinical sample validation.

The longitudinal study was conducted over the initial 2 years of the COVID-19 pandemic, spanning from June 2020 to December 2022, in healthcare workers (HCWs) of the Thomayer University Hospital. A total of 3892 blood samples were collected and analyzed for total nucleocapsid (N) antibodies. The aim of the study was to evaluate the dynamics of N antibodies, their relationship to the PCR test, spike (S) antibodies, interferon-gamma, and prediction of reinfection with SARS-CoV-2.

To determine the association between IGF2BP2 polymorphisms and type 2 diabetes mellitus.

Acute lymphocytic leukemia (ALL), characterized by uncontrolled growth of abnormal lymphocytes, predominantly affects children. Genetic analysis focusing on genes and microRNAs reveals important information about the biology of ALL, enabling accurate diagnosis and treatment. This study examines gene and microRNA expression in B cell ALL to improve early diagnosis and personalized treatment.

Pseudomonas aeruginosa is a significant opportunistic pathogen, especially in hospital-acquired infections, with plasmid-mediated fluoroquinolone resistance posing a major healthcare threat. This research aimed to isolate fluoroquinolone-resistant P. aeruginosa from patients at Aleppo University Hospital, assess the prevalence of fluoroquinolone resistance, confirm molecular identity, identify plasmid-associated resistance genes, and investigate virulence factors.

The management of multiple myeloma is challenging because the disease is incurable and unexpected relapses can threaten a patient's survival. Several assessment systems are currently available, but they often require invasive or costly procedures (e.g., instrumental bone marrow and whole-body examinations) or rely on non-specific markers in blood and urine that may not be sufficient to assess and monitor the disease.

To determine the predictive value of the atherogenic index of plasma before transplant for delayed graft function.

In this study, we attempted to select the optimum cases for a prostate biopsy based on routine laboratory test results in addition to prostate-specific antigen (PSA) blood test using H2O automated machine learning (AutoML) software, which includes many common machine learning algorithms.

As a complex disease, hypertension (HTN) is influenced by both genetic and environmental factors and their interaction. The calcium signaling pathway is known to be involved in the regulation of blood pressure, and dysfunction in this pathway may contribute to the development of hypertension. Genome-wide association studies (GWAS) have identified several genes in the calcium signaling pathway associated with susceptibility to HTN, including PLCB1, ATP2B1, and ADRB1. The aim of this study was to investigate the possible association between single nucleotide variants (SNVs) in the calcium signaling pathway and HTN.

Hepatocellular carcinoma (HCC) is a ubiquitous malignancy linked to significant mortality. The abnormal expression of β-1,4-N-acetyl-galactosaminyltransferase 1 (B4GALNT1) seemed to be implicated in tumorigenesis. Nonetheless, this enzyme's roles in HCC are unclear.

The objective of this study was to investigate the antibody to RBC in autoimmune disease patients with ANA using sensitive Coombs test based on flow cytometry method.

To explore the impact of in vitro cell subculture on prenatal diagnostic sample results and compare the efficacy of conventional karyotyping and chromosomal microarray analysis (CMA) in detecting chromosome mosaicism.

SAP2 is closely associated with the pathogenicity and drug resistance of Candida albicans (C. albicans). Our study aimed to construct C. albicans with SAP2 overexpression (pRB895-SAP2-SC5314) to explore the influence of SAP2 on the adhesion of C. albicans and predict the interaction between magnolol and Sap2 by molecular docking.

Neurofilament light chain (NfL) is one of the most important biomarkers in the field of clinical neurochemistry. Several analytical methods have been developed in the last decade. Recently, Fujirebio introduced a ready-to-use assay kit for measuring NfL levels in the cerebrospinal fluid (CSF) on the fully automated LUMIPULSE G System. In this study, we established the decisional cutoffs for CSF NfL.

Sphingolipidoses are rare inherited metabolic diseases belonging to lysosomal diseases. Early and accurate diagnosis is crucial for effective management and treatment. In this study, we aimed to develop a robust method to accelerate the diagnosis of these sphingolipidoses using dried blood spots and plasma.

Research on heart injury caused by COVID-19 is limited to large observational and retrospective cohort studies using imaging or pathological data. Reported changes in the levels of myocardial markers in severe diseases have been limited, with few studies on mild infections. The effects of COVID-19 on cardiac function and changes in myocardial marker levels have not yet been reported.

Inductively coupled plasma mass spectrometry (ICP-MS) is widely used for the accurate measurement of minerals. However, its application to serum essential mineral measurement has not been fully evaluated. The present study aimed to assess the performance of ICP-MS for serum minerals by comparing its measurements to those obtained using standard quantification methods.

Mycoplasma pneumoniae (MP) is a major cause of community-acquired pneumonia (CAP), posing diagnostic challenges. This study evaluates novel inflammatory biomarkers, including neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII) and system inflammation response index (SIRI) for MP diagnosis in children.

Thromboelastography (TEG) and coagulation tests can be used to detect hypercoagulability to assess thrombus formation. This study explored the association between TEG and coagulation in evaluating disease severity in elderly patients with lower extremity arteriosclerotic occlusive disease (LEASO), aimed to provide surgical treatment guideline.

In the oral environment, the production of bacteriocins or antimicrobial peptides (AMPs) plays a crucial role in maintaining ecological balance by impeding the proliferation of closely related microorganisms. This study aims to conduct in silico genome screening of Streptococcus salivarius to identify potential antimicrobial compounds existing as hypothetical peptides, with the goal of developing novel synthetic antimicrobial peptides.
