In this study, human induced pluripotent stem cells (hiPSCs) were successfully differentiated into cardiomyocytes and subsequently used to generate spheroids via the hanging drop method. We comprehensively characterized the formation, fusion, and beating capability of the generated spheroids.

Adsorptive cathodic stripping voltammetric determination of aluminum at ng mL −1 levels in salt samples based on the metal complexation with Calcon (1-(2-hydroxynaphthylazo)-2 naphthol-4-sulfonic acid) and the subsequent adsorptive deposition onto a hanging mercury drop electrode was studied. Central composite design was used as a design method. Several chemical and instrumental parameters (pH, ligand concentration, deposition time, deposition potential, and complexing time) were involved in the experimental design.

Determination of zineb in tap water and tomato samples by adsorptive catalytic stripping voltammetry
This paper describes a sensitive and accurate adsorptive catalytic stripping voltammetric method for the determination of zineb (zinc ethylene-bis- dithiocarbamate) in tap water and tomato samples. The method is based on the reduction of adsorbed zineb at a hanging mercury drop electrode following its catalytic oxidation using peroxydisulfate as an oxidizing reagent. Chemical and instrumental parameters of the process were optimized.

The simultaneous determination of Zn2+, Cd2+, Cu2+, Pb2+ in acid mine drainage (AMD) by differential pulse-anodic stripping voltammetrics (DPASV) with high sensitivity, selectivity, and accuracy is difficult because of many influential factors in the waste-water. This paper presents the results of studying supporting electrolyte for simultaneous determination of these ions in AMD in Mao Khe, Quang Ninh province to serve the wastewater treatment process.

In this study, we compared the pollen quantity, viability and in vitro pollen germination of M1 and M2 type flowers of nine longan genotypes. Acetocarmine, 2, 3, 5-triphenyl tetrazolium chloride, 2, 5-diphenyl monotetrazolium bromide and aniline blue-lectophenol staining methods were used for pollen viability assessment while different concentrations of sucrose, boric acid (H3BO3) and agar were used for in vitro pollen germination test through hanging drop technique.

Induced Pluripotent stem cells (iPSC) technology is involved in advancing the field of disease modelling and cell transplantation. Stem cell can differentiate under appropriate in vitro and in vivo conditions into different cell types. Under this study, we analysed the establishment of in vitro expression of GATA4 gene in cardiac differentiated canine iPSC. In vitro differentiation of canine iPSCs via embryoid bodies (EBs) was produced by ‘Hanging Drop’ method. EB’s were differentiated by using cardiac differentiation media.

A new procedure is presented for the determination of low concentrations of lead and cadmium in water samples. Ligand assisted pseudo-stir bar hollow fiber solid/liquid phase microextraction using sol–gel sorbent reinforced with carbon nanotubes was combined with differential pulse anodic stripping voltammetry for simultaneous determination of cadmium and lead in tap water, and Darongar river water samples.

The pollen grains of 32 different walnut cultivars and types were tested in vitro to determine their viability, germination ability, and pollen production level. Viability of pollens was determined by TTC and FDA tests. The hanging drop method and agar in petri method were used for pollen germination.
