Performance Comparison between Semi‐Automated and Manual Cell Counting for Animal Cell Culture
Following ISO 20391‐2:2019 guidelines, manual and semi‐automated cell counting performances were compared using validation parameters from ICH Q2(R1). Specificity, linearity, and repeatability served as key validation parameters in the evaluation of total cell density and cell viability of CHO‐K1 cells using trypan blue exclusion staining.

Abstract On the centennial of higher education in Chemical Engineering in Mexico, it is pertinent to revisit the key stages that have contributed to its consolidation as a vital discipline for the nation's scientific and technological advancement. Although the initial mission of chemical engineering education was primarily oriented toward the training ...

Identifizierung und Charakterisierung eines neuen Bindeproteins für zyklische Nukleotide [PDF]
Cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate are important intracellular messengers. Binding of cyclic nucleotides controls the activity of protein kinases, ion channels and guanine-nucleotide-exchange factors in many cells ...

Abstract Quantitative risk assessments of chemicals are routinely performed using in vivo data from rodents; however, there is growing recognition that non‐animal approaches can be human‐relevant alternatives. There is an urgent need to build confidence in non‐animal alternatives given the international support to reduce the use of animals in toxicity ...

ABSTRACT Gene mutations can be detected in mammalian cells in vitro using indicator genes such as the hypoxanthine‐guanine‐phosphoribosyltransferase (HPRT) gene. These assays have been adopted as OECD test guidelines (TG, e.g., OECD TG no. 476) and are used for regulatory purposes.

Study of Ultraviolet-Induces Chromatid and Chromosome Aberrations as a Function of Dose in G1 Phase Vertebrate Tissue Cultures [PDF]
G1 phase A8 Xenopus laevis (toad) and V79B Cricetulus griseus (hamster) tissue cultures were used to observe the frequency of ultraviolet-induced chromosomal aberrations as a function of dose.

Mechanisms of SCN2A loss of function do not predict presence or phenotype of epilepsy
Abstract Objective SCN2A loss‐of‐function (LoF) variants are associated with epilepsy (onset age ≥ 3 months), intellectual disability (ID), and autism spectrum disorder (ASD). Despite numerous identified variants and the description of phenotypic subgroups, relationships between Nav1.2 channel dysfunction and clinical phenotypes remain unclear.
