miR-513b-5p inhibits the proliferation and promotes apoptosis of retinoblastoma cells by targeting TRIB1.

MicroRNAs are involved in the pathogenesis of various human malignant tumors. This study aims to explore the role of miR-513b-5p in the malignant proliferation of retinoblastoma (RB) cells and its potential molecular mechanisms. The function-gain and function-loss experiments were performed in Weri-RB1 cells using miR-513b-5 mimics and inhibitors.

Inductively Coupled Plasma Mass Spectrometry as a Reference Method to Evaluate Serum Calcium Measurement Bias and the Commutability of Processed Materials during Routine Measurements.

Background: Measuring total serum calcium is important for the diagnosis of diseases. Currently, results from commercial kits for calcium measurement are variable. Generally, the performance of serum calcium measurements is monitored by external quality assessment (EQA) or proficiency testing schemes.

Combining corneal crosslinking and phakic toric Implantable Collamer Lenses for the treatment of keratectasia: A case report.

The present study reports the use of a phakic toric Implantable Collamer Lens (ICL) that improved the refraction correction of high myopia and astigmatism in a case of keratectasia following corneal cross-linking. A 31-year-old male was diagnosed with keratectasia 12 years after laser-assisted keratomileusis (LASIK). Following LASIK, the manifest refraction was -3.

[Clinical analysis of ultrasound-guided embryo transfer after in-vitro fertilization].

Objective: To investigate whether ultrasound (US) guided embryo transfer could improve pregnancy rates.

Methods: A prospective randomized trial was conducted to compare embryo transfer under abdominal US guidance (n = 178) with traditional embryo transfer (n = 152).

Results: The clinical pregnancy rate was 37.
