Möbius Band Surprise: A Systematic Illusion in Imagery.

Iperception

Department of Psychosocial Science, University of Bergen, Norway.

Published: April 2021

When a Möbius loop is cut along the middle of the band, the result is a single connected loop, yet anecdotal evidence from science demonstrations and the use of this effect in magic tricks suggest that most people are thoroughly surprised by this because they strongly believe that the result should be two separate loops. Here, we present results from a behavioral experiment confirming this anecdotal evidence and discuss potential theoretical explanations for why this demonstration evokes strong, but misleading intuitions and a related illusion of impossibility.

Signaling pathways play key roles in many important biological processes, such as cell division, differentiation, and migration. Phosphorylation site-specific antibodies specifically target proteins phosphorylated on a given tyrosine, threonine, or serine residue. The use of phospho-specific antibodies facilitates the analysis of signaling pathway regulation and activity.

Background: Preclinical studies and anecdotal case reports support the potential therapeutic benefit of low-dose oral ketamine as a treatment of clinical symptoms in Rett syndrome (RTT); however, no controlled studies have been conducted in RTT to evaluate safety, tolerability and efficacy.

Design: This was a sequentially initiated, dose-escalating cohort, placebo-controlled, double blind, randomized sequence, cross-over study of oral ketamine in 6-12-year-old girls with RTT to evaluate short-term safety and tolerability and explore efficacy.

Methods: Participants were randomized to either five days treatment with oral ketamine or matched placebo, followed by a nine-day wash-out period and then crossed-over to the opposite treatment.

Introduction: Social prescribing links patients to community groups and services to meet health needs; however, it is uncertain what the benefits and impacts of social prescribing are for people with chronic pain. The National Institute for Health and Care Excellence (NICE) undertook a systematic review to investigate the clinical and cost effectiveness of social interventions aimed at improving the quality of life of people with chronic pain; no relevant clinical studies comparing social interventions with standard care for chronic pain were found, though the inclusion criteria for studies was narrow.

Objectives: To undertake a rapid review of all types of research and policy on social prescribing for adults with chronic pain in the U.

Background: The health and well-being of refugees are critically compromised by harsh living conditions, which foster the emergence of infectious diseases and the misuse of antimicrobial agents. This multicentre cross-sectional community-based study investigated the prevalence of urine carriage of bacteria and the associated antimicrobial resistance patterns among Syrian refugees living in makeshift camps in Lebanon, an East Mediterranean country.

Methods: We used multivariable logistic regression models to identify the risk factors associated with bacteriuria in this vulnerable population.
