This review aimed at summarizing the literature evidence on clinical, cognitive, and neurobiological correlates of impaired timing abilities in schizophrenia (SCZ). Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic literature search was conducted in PubMed, EMBASE, and PsycInfo by looking at correlates between timing abilities and either symptom severity, cognition, and neurobiological data (imaging and electroencephalography) in individuals with SCZ, without restrictions on study design. A total of 45 articles were selected: associations were identified between impaired timing performance and positive, negative, and disorganization symptoms, as well as with executive functioning, working memory, and attention.

- - Culicoides spp., small biting midges, are important vectors of viruses like African horse sickness and bluetongue that affect livestock; a study in Yunnan Province, China examined their diversity and abundance on two cattle farms from March 2022 to March 2023.
- - Light traps collected 19 species of Culicoides, with C. oxystoma being the most prevalent, making up over 63% of the total 8,343 specimens; 10 species were screened for several viruses using RT-qPCR.
- - Notably, one strain of Yunnan Orbivirus was isolated from cattle blood, and the first connection between a totivirus (YSToV) and Culicoides was found
Article Synopsis
- Iron homeostasis is crucial for organisms as it facilitates essential biochemical functions but can be toxic in excess, which is regulated by the protein Fur in bacteria.
- The HpFur protein in Helicobacter pylori uniquely acts as a transcriptional commutator, with its apo- and holo- forms serving as different repressors that bind DNA in distinct ways for various target genes.
- The study proposes a comprehensive redefinition of holo-HpFur regulatory targets using RNA-seq and ChIP-seq data, uncovering new coding sequences and non-coding RNAs influenced by iron availability, thereby enriching the understanding of this protein's regulatory roles.
Background: Virtual reality (VR) technology has become increasingly used for assessment and intervention in the neuroscience field.
Objective: We aimed to investigate the effects of a VR Training System, named VRADA (VR Exercise App for Dementia and Alzheimer's Patients), on the cognitive functioning of older people with mild cognitive impairment (MCI).
Methods: In this intervention study, 122 older adults with MCI were randomly assigned to five groups (the VRADA group ( = 28), a bike group ( = 11), a physical exercise group ( = 24), a mixed group (physical and cognitive exercise) ( = 31), and a non-contact control group ( = 28).
As an additive manufacturing process, material jetting techniques allow to selectively deposit droplets of materials in liquid or powder form through a small-diameter aperture, such as a nozzle of a print head. For the fabrication of printed electronics, a variety of inks and dispersions of functional materials can be deposited by drop-on-demand printing on rigid and flexible substrates. In this work, zero-dimensional multi-layer shell-structured fullerene material, also known as carbon nano-onion (CNO) or onion-like carbon, is printed on polyethylene terephthalate substrates using drop-on-demand inkjet printing.
