Response to an applied electric field in an antiferroelectric 1/2 subphase: The role of thermal fluctuations.

Phys Rev E

June 2023

Department of Materials Science and Engineering, School of Materials and Chemical Technology, Tokyo Institute of Technology, 2-12-1 S8-28, Ookayama, Meguro-ku, Tokyo 152-8552, Japan.

Article Synopsis
  • The study examines the response of a specific subphase in a binary liquid crystal mixture when subjected to an electric field, utilizing specially aligned cells.
  • In the antiferroelectric phases, distortions in the structure induce polarization that aligns with the electric field, but in the 1/2 subphase, the structure initially resists deformation, leading to a significant change in optical properties at low electric field strengths.
  • The findings suggest that thermal fluctuations are crucial in facilitating a reorientation of the liquid crystal structure, contributing to a unique switching behavior seen in certain liquid crystal displays.

With an incidence of more than > 1,000,000/day, sexually transmitted diseases remain a major challenge for health care systems worldwide. To reduce disease burden, complications, and spread, rapid diagnosis permitting early therapy is pivotal. The range of pathogens is wide and co-infections are common.

A line of contacting hard spheres, placed in a transverse confining potential, buckles under compression or when tilted away from the horizontal, once a critical tilt angle is exceeded. This interesting nonlinear problem is enriched by the combined application of both compression and tilt. In a continuous formulation, the profile of transverse sphere displacement is well described by numerical solutions of a second-order differential equation (provided that buckling is not of large amplitude).

Herein the synthesis of 1,8-naphthalimides functionalised as the 3,4-dihydroxy-1,8-naphthalimide (catechol, Nap-Cat) and the corresponding 15-crown-5 (Nap-Crown) is reported. These compounds represent the first examples where these two recognition groups are directly incorporated into the 1,8-naphthalimide ring system. Both Nap-Cat and Nap-Crown were evaluated for their capacity to respond to analytes such as HO (a mimic for cellular oxidation) and metal ions (as elements of environmental and physiological interest).

Healthcare is increasingly delivered closer to the patients' homes, which increases the level of responsibility that patients and informal carers take for managing their medication-taking, although this is associated with hazards. Medication self-management has been conceptualised as work taking place in non-formal settings ( , households), which are complex systems. Human factors and ergonomics (HFE) models provide a framework for studying such systems.

Unlabelled: WHAT IS KNOWN ON THE SUBJECT?: Traditionally, treatment for eating disorders (EDs) has been provided on an inpatient or outpatient basis, but more recently other levels of treatment provision to include, day care (DC) and community outreach programmes, have been developed. There is limited research exploring the experience of patients who have transitioned from inpatient ED treatment to a remote DC treatment. This lack of knowledge can impact mental health nurses' understanding of what that experience is like for patients and hence may influence the efficacy of collaboration and inclusion between patients and nurses.

Background: Detecting impaired naming capacity contributes to the detection of mild (MildND) and major (MajorND) neurocognitive disorder due to Alzheimer's disease (AD). The Test for Finding Word retrieval deficits (WoFi) is a new, 50-item, auditory stimuli-based instrument.

Objective: The study aimed to adapt WoFi to the Greek language, to develop a short version of WoFi (WoFi-brief), to compare the item frequency and the utility of both instruments with the naming subtest of the widely used Addenbrooke's cognitive examination III (ACEIIINaming) in detecting MildND and MajorND due to AD.

Objective: To co-design a website aimed to empower youth to ask questions to encourage productive, meaningful conversations with their health care providers.

Methods: The research team recruited adolescent stakeholders (ages 11-17) through flyers distributed at local Young Men's Christian Association (YMCA) locations, clinics, and school nurses. Eleven adolescents who had at least one chronic medical condition were selected as members of the two youth advisory boards.

Chronic IFNα treatment induces leukopoiesis, increased plasma succinate and immune cell metabolic rewiring.

Although clinically effective, the actions of IFNα, either produced endogenously or by therapeutic delivery, remain poorly understood. Emblematic of this research gap is the disparate array of notable side effects that occur in susceptible individuals, such as neuropsychiatric consequences, autoimmune phenomena, and infectious complications. We hypothesised that these complications are driven at least in part by dysregulated cellular metabolism.

The COVID-19 pandemic linked to the virus SARS-CoV-2, which began in China, affected ∼765 million people as of 30 April 2023. The widespread use of corticosteroids for the symptomatic treatment of COVID-19 could lead to the reactivation of infections of opportunistic pathogens, including Strongyloides. We sought to determine the clinical symptoms and demographic characteristics of SARS-CoV-2-Strongyloides co-infection, particularly in patients with severe disease and being treated with immunosuppressive drugs.

Background: Deviation from a normal bite can be defined as malocclusion. Orthodontic treatment takes 20 months on average to correct malocclusion. Accelerating the rate of tooth movement may help to reduce the duration of orthodontic treatment and associated unwanted effects including orthodontically induced inflammatory root resorption (OIIRR), demineralisation and reduced patient motivation and compliance.

The Collicular-Pulvinar-Amygdala Axis and Adult-Onset Idiopathic Focal Dystonias.

Adv Neurobiol

June 2023

Trinity Centre for Biomedical Engineering, Trinity College Dublin, The University of Dublin, Dublin 2, Ireland.

Adult-onset idiopathic focal dystonias (AOIFD) are the most common type of dystonia. It has varied expression including multiple motor (depending on body part affected) and non-motor symptoms (psychiatric, cognitive and sensory). The motor symptoms are usually the main reason for presentation and are most often treated with botulinum toxin.

Neuromodulation in Dystonia - Harnessing the Network.

Adv Neurobiol

June 2023

School of Medicine, Trinity College, The University of Dublin, Dublin, Ireland.

Adult-onset isolated focal dystonia (AOIFD) is a network disorder characterised by abnormalities of sensory processing and motor control. These network abnormalities give rise to both the phenomenology of dystonia and the epiphenomena of altered plasticity and loss of intracortical inhibition. Existing modalities of deep brain stimulation effectively modulate parts of this network but are limited both in terms of targets and invasiveness.

Background: Even though communities in low-resource areas across the globe are aging, older adult mental and cognitive health services remain mainly embedded in tertiary- or secondary hospital settings, and thus not easily accessible by older adults living in such communities. Here, the iterative development of INTegRated InterveNtion of pSychogerIatric Care (INTRINSIC) services addressing the mental and cognitive healthcare needs of older adults residing in low-resource areas of Greece is depicted.

Methods: INTRINSIC was developed and piloted in three iterative phases: (i) INTRINSIC initial version conceptualization; (ii) A 5-year field testing in Andros island; and (iii) Extending the services.
