A simple device has been developed for delivering samples into a flow cytometer. Designed with economy, simplicity, and flexibility in mind, this device, having only one moving part, can be used for sample volumes as small as 20 microliter, for virtually any form of cell sample container, and for a wide range of cell concentrations. It consists essentially of a lever-operated disc valve that allows the cell sample to be loaded into a loop of tubing and then to be injected into the cytometer nozzle under pressure from a saline source. The sampler has lifted the maximum analytical throughput of a FACS II cell sorter to better than 120 samples per hour.

Microfluidic impedance cytometry (MIC) is a label-free technique that characterizes individual flowing particles/cells based on their interaction with a multifrequency electric field. The technique has been successfully applied in different scenarios including life-science research, diagnostics, and environmental monitoring. The aim of this review is to illustrate the fascinating opportunities enabled by the integration of MIC with other microfluidic tools.

Thanks to the plummeting costs of continuously evolving omics analytical platforms, research centers collect multiomics data more routinely. They are, however, confronted with the lack of a versatile software solution to harmoniously analyze single-omics and interpret multiomics data. We have developed iSODA, a web-based application for the analysis of single- and multiomics data.

Background: Infertility was often considered a female issue, but male infertility emerged significantly after the Covid-19 pandemic. Hence, assessments are crucial for planning policies on health care and family planning and reasons thereof post vaccinations.
Material And Methods: The present study was a case-control, dual-centers, prospective study with normal sperm parameters.

Background: Since there is currently no cure for amyotrophic lateral sclerosis (ALS), it is essential to search for diagnostic biomarkers and novel treatments to reduce the severity of this disease. One of these treatment approaches is stem cell transplantation.
Objective: This study aims to evaluate the safety and efficacy of repeated transplantation of autologous bone marrow-derived mesenchymal stem cells (BM-MSCs) in patients with ALS by analyzing clinical and molecular data.

Introduction: Circulating tumor cells (CTCs) have attracted significant interest as a biomarker for cancer diagnosis. In this study, we judiciously constructed a recombinant MUC1-dependent adenovirus (rAdF35-MUC1) that can selectively replicate and overexpress copepod super green fluorescent proteins (copGFP) in MUC1-positive tumor cells to investigate its role in the detection of CTCs.
Methods: We conducted a comparative study between rAdF35-MUC1 and the existing hTERT-dependent adenovirus (rAdF35-hTERT).
