Beneficial effects of metformin treatment on memory impairment.

Memory issues are a prevalent symptom in different neurodegenerative diseases and can also manifest in certain psychiatric conditions. Despite limited medications approved for treating memory problems, research suggests a lack of sufficient options in the market. Studies indicate that a significant percentage of elderly individuals experience various forms of memory disorders.

Different types and epidemiological patterns of calcaneal fractures based on reviewing CT images of 957 fractures.

Introduction: Calcaneal fractures may have lifelong debilitating sequences, if not treated properly. Identifying different types of calcaneal fractures based on the computed tomography (CT) scans can increase our conception about these fractures.

Methods: In a cross-sectional study, the available CT images of all consecutive patients with the diagnosis of calcaneal fracture, from January 2015 to December 2018, were reviewed to determine different patterns and types of these fractures.

Carbon dots on VO nanowires are a viable peroxidase mimic for colorimetric determination of hydrogen peroxide and glucose.

A nanocomposite was hydrothermally prepared from C-dots and VO nanowires, and characterized by TEM, FTIR and XRD. Due to the synergistic effects between C-dots and VO nanowires, the nanocomposite is found to possess peroxidase-mimicking activity. This finding was exploited to design colorimetric methods for determination of HO and glucose (via glucose oxidase) by using of 3,3',5,5'-tetramethylbenzidine (TMB) as the chromogenic substrate.
