Evaluation of the fully automated urine particle analyzer UF‐1500

  •  2 December 2023

Graphical Abstract

Description unavailable

The novel and compact model of the fully automated urine particle analyzer UF-1500 was evaluated. The performance of the UF-1500 is comparable to that of the existing UF-5000 analyzer. The UF-1500 was suitable to be introduced in clinical practice, but a manual microscopic examination is necessary for the samples with false-positive or false-negative results.

Performance evaluation of sperm concentration, motility, and morphological analysis for GSA-810 series of sperm quality analysis system

  •  27 November 2023

Graphical Abstract

Description unavailable

The GSA-810 system can accurately detect sperm concentration in semen samples with sperm concentrations in the range of (2–100) × 106/mL. Semen samples with a sperm concentration between 50 × 106/mL and 100 × 106/mL can be directly detected using the GSA-810 system without dilution. The higher the sperm concentration and PR, the better the repeatability of the detection results.

A novel cuproptosis‐related prognostic gene signature in adrenocortical carcinoma

  •  23 November 2023

Graphical Abstract

Description unavailable

Validation of independent prognostic factors of the cuproptosis-related risk score (CRRS) using a survival curve and a time-dependent ROC (A). CDKN2A and FDX1 expressions were independent prognostic predictors of ACC patients, and low expression of CDKN2A (B) and FDX1 (C) was associated with better survival outcomes.

Cell-free DNA extraction from urine of lung cancer patients and healthy individuals: Evaluation of a simple method using sample volume up-scaling

  •  22 November 2023

Graphical Abstract

Description unavailable

Only at alkaline pH levels EDTA is a reliable preservative for cfDNA in urine. Moreover, it was found that urine volume up-scaling (>5 mL) is mandatory if the mutation allele frequency is less than 1%. A similar amount of small-sized cfDNA targets were detected in three different gene sites indicating a non-random distribution pattern across genes.

Application of the cell-based RT-qPCR assay (C-QPA) for potency detection of the novel trivalent rotavirus vaccine in China

  •  17 November 2023

Graphical Abstract

Description unavailable

The linear range of C-QPA. The correlation coefficients (R2) of the three strains ranged from 0.97 to 0.98, indicating a good linearity between the UIs and the dilutions. According to the linear regression analysis, the linear range of the assay for G2 (LD9, red line), G3 (LS4/9, green line) and G4 (LH9, blue line) was 2.0–6.5, 3.9–8.3 and 3.5–8.1 UI, respectively.

Cryptic exon activation caused by a novel deep‐intronic splice‐altering variant in Becker muscular dystrophy

  •  15 November 2023

Graphical Abstract

Description unavailable

Our study successfully identified a novel deep-intronic splice-altering variant in DMD via the combined application of dystrophin mRNA analysis, genomic Sanger sequencing, and in silico bioinformatic analyses. The novel deep-intronic variant (c.8217 + 23338A > G) resulted in the activation of a new dystrophin cryptic exon, which confirmed the genetic diagnosis of dystrophinopathy in our patient.

Combinational antibody detection approach increases the clinical validity of colorectal cancer screening

  •  14 November 2023

Graphical Abstract

Description unavailable

The AUC values increased in the combined ROC analysis compared with the individual ROC analysis. Using a combination antibody detection approach of tumor markers for CRC diagnosis has the potential to be an effective approach. Therefore, the use of serum protein biomarkers holds promise for the development of inexpensive, noninvasive, and inexpensive tests for the detection of CRC.

SNHG1/miR‐21 axis mediates the cardioprotective role of aloin in sepsis through modulating cardiac cell viability and inflammatory responses

  •  10 November 2023

Graphical Abstract

Description unavailable

(A,B) The myocardial damage markers cTnI and BNP were increased by CLP in mice, but was reduced by aloin treatment in CLP-treated mice model. (C,D) CLP treatment had inhibitory effects on LVEF and +dp/dtmax, and had promotion effects on –dp/dtmax, but aloin alleviated these effects. (E,F) CLP treatment increased the levels of IL-1β and TNF-α in mice, and the effects of CLP on mice were alleviated by aloin. **p < 0.01, ***p < 0.001 versus Sham group; ##p < 0.01, ###p < 0.001 versus CLP group. BNP, brain natriuretic peptide; CLP, cecal ligation and puncture; cTnI, cardiac troponin I; IL-1β, interleukin 1β; LVEF, left ventricular ejection fraction; TNF-α, tumor necrosis factor alpha.
