Onychomatricoma is a rare benign tumour of the nail matrix first described in 1992, and since then, no more than 80 cases have been reported. Despite distinct clinical characteristics, it is frequently misdiagnosed as onychomycosis partly due to remaining an unknown entity. The authors present the case of a patient with a 30-year history of nail abnormalities with more recent growth to alarming dimensions.

The ability to control the growth and orientation of neurites over long distances has significant implications for regenerative therapies and the development of physiologically relevant brain tissue models. In this study, the forces generated on magnetic nanoparticles internalised within intracellular endosomes are used to direct the orientation of neuronal outgrowth in cell cultures. Following differentiation, neurite orientation was observed after 3 days application of magnetic forces to human neuroblastoma (SH-SY5Y) cells, and after 4 days application to rat cortical primary neurons.

Human glucokinase (GCK) functions as a glucose sensor in the pancreas and liver, where GCK activity regulates insulin secretion and glycogen synthesis, respectively. GCK's low affinity for glucose and the sigmoidal substrate dependency of enzymatic turnover enables it to act as a sensor that makes cells responsive to changes in circulating glucose levels. Its unusual kinetic properties are intrinsically linked to the enzyme's conformational dynamics.

Public transport represents a potential site for the transmission of resistant pathogens due to the rapid movement of large numbers of people. This study aimed to investigate the bacterial contamination of frequently touched surfaces in the public transport system operating in the proximity of the biggest Czech hospital during the coronavirus pandemic despite extensive cleaning and disinfection efforts. In June and September 2020, samples from the metro trains, ground transport and stationary objects were collected, enriched and cultured.

Background: Alzheimer's disease (AD) is the most common form of dementia. Neuropathologically, AD stands out as a mixed proteinopathy. Beta-amyloid and tau biomarkers can now add in-vivo support to the AD diagnosis.

Graphene and its derivatives have been widely used as reinforcing nanofillers for high-performance polymer nanocomposites. The effectiveness of the reinforcement largely depends on the properties of the nanofiller-matrix interface, which can be represented by the interfacial shear strength (IFSS). This work systematically investigates IFSS enhancements for polyethylene (PE) nanocomposites reinforced by graphene origami (GOri) through molecular dynamics pull-out simulations.
