Opening the Pandora Box: Neural processing of self-relevant negative social information.

Curiosity is a powerful motivator of information-seeking behavior. People seek not only positive, but also aversive social information about others. However, whether people also seek unfavorable social information about themselves, as well as the neural mechanisms that may drive such seemingly counterintuitive behavior remain unclear.

How does mindfulness skills training work to improve emotion dysregulation in borderline personality disorder?

Background: Mindfulness skills training is a core component of Dialectical Behavior Therapy and aims to improve emotion dysregulation (ED) in people with Borderline Personality Disorder (BPD). However, the underlying mechanisms of change are not fully understood.

Methods: A total of 75 BPD outpatients participated in a 10-week mindfulness skills training.

Implementation of a robotic surgical practice in inflammatory bowel disease.

Robotics adoption has increased in colorectal surgery. While there are well-established advantages and standardised techniques for cancer patients, the use of robotic surgery in inflammatory bowel disease (IBD) has not been studied yet. To evaluate the feasibility and safety of robotic surgery for IBD patients.

The Effect of Dietary Components of the Mediterranean Diet on Food Allergies: A Systematic Review.

Allergies are a common and increasing health problem affecting millions of people worldwide. This increase is attributed to genetic predisposition, air pollution, climate change, lack of physical activity, and alterations in eating habits. The Mediterranean diet (MD), which includes a lot of fruits and vegetables, whole grains, legumes, nuts, olive oil, and fish, has been linked to a variety of health benefits, including a lower risk of chronic and allergic disease.

Pathogenic and Low-Frequency Variants in Children With Central Precocious Puberty.

Background: Central precocious puberty (CPP) due to premature activation of GnRH secretion results in early epiphyseal fusion and to a significant compromise in the achieved final adult height. Currently, few genetic determinants of children with CPP have been described. In this translational study, rare sequence variants in , , , and genes were investigated in patients with CPP.

Moving the human biology program from face-to-face to online delivery mode in the time of COVID-19.

Following the COVID-19 lockdown, the BSc in Human Biology Program of the University of Nicosia switched from face-to-face to online delivery mode. Herein we describe how we identified and managed the challenges that arose to successfully complete the Semester.

Student learning about UK health services in a cross-border curriculum partnership; the London-Cyprus experience.

This article was migrated. The article was marked as recommended. Purpose of the article Cross border partnerships require curricula, faculty and students to negotiate challenges associated with national regulatory frameworks, contexts and cultures.

Reward and Punishment Sensitivity in Borderline and Avoidant Personality Disorders.

The authors compared self-reported and behavioral responses to reward and punishment in individuals diagnosed with borderline personality disorder (BPD) or avoidant personality disorder (APD) relative to a healthy comparison (HC) group. As predicted, self-reported sensitivity to reward was significantly higher in the BPD group than in the APD and HC groups. Also as predicted, self-reported sensitivity to punishment was significantly elevated in both disordered groups but significantly higher in APD than in BPD.

The Spectrum of Genetic Defects in Congenital Adrenal Hyperplasia in the Population of Cyprus: A Retrospective Analysis.

Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) is caused by mutations in the gene. The study refers to CAH patients of Greek-Cypriot ancestry between years 2007 and 2018. One hundred and twenty patients with various degrees of CAH were categorized and genotyped.

Transforming a cookbook undergraduate microbiology laboratory to inquiry based using a semester-long PBL case study.

Microbial physiology is a basic course taught throughout biomedical science disciplines. Students study the structure, growth, and metabolism of microorganisms and often find it difficult to learn the information, usually because they fail to see the wider applications. The current microbiology laboratory series describes how to transform a "cookbook" undergraduate laboratory to an inquiry-based one by incorporating problem-based learning.

In silico analysis of a novel MKRN3 missense mutation in familial central precocious puberty.

Background: The onset of puberty is influenced by the interplay of stimulating and restraining factors, many of which have a genetic origin. Premature activation of the GnRH secretion in central precocious puberty (CPP) may arise either from gain-of-function mutations of the KISS1 and KISS1R genes or from loss-of-function manner mutations of the MKRN3 gene leading to MKRN3 deficiency.

Objective: To explore the genetic causes responsible for CPP and the potential role of the RING finger protein 3 (MKRN3) gene.

Differential calcium signaling and Kv1.3 trafficking to the immunological synapse in systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) T cells exhibit several activation signaling anomalies including defective Ca(2+) response and increased NF-AT nuclear translocation. The duration of the Ca(2+) signal is critical in the activation of specific transcription factors and a sustained Ca(2+) response activates NF-AT. Yet, the distribution of Ca(2+) responses in SLE T cells is not known.

Localization of Kv1.3 channels in the immunological synapse modulates the calcium response to antigen stimulation in T lymphocytes.

The immunological synapse (IS), a highly organized structure that forms at the point of contact between a T cell and an APC, is essential for the proper development of signaling events, including the Ca(2+) response. Kv1.3 channels control Ca(2+) homeostasis in human T cells and move into the IS upon Ag presentation.

Engagement of the CD4 receptor affects the redistribution of Lck to the immunological synapse in primary T cells: implications for T-cell activation during human immunodeficiency virus type 1 infection.

Understanding the molecular mechanisms underlying dysregulated immune responses in human immunodeficiency virus type 1 (HIV-1) infection is crucial for the control of HIV/AIDS. Despite the postulate that HIV envelope glycoprotein gp120-CD4 interactions lead to impaired T-cell responses, the precise mechanisms underlying such association are not clear. To address this, we analyzed Lck and F-actin redistribution into the immunological synapse in stimulated human primary CD4(+) T cells from HIV-1-infected donors.

Altered dynamics of Kv1.3 channel compartmentalization in the immunological synapse in systemic lupus erythematosus.

Aberrant T cell responses during T cell activation and immunological synapse (IS) formation have been described in systemic lupus erythematosus (SLE). Kv1.3 potassium channels are expressed in T cells where they compartmentalize at the IS and play a key role in T cell activation by modulating Ca(2+) influx.

The Ca(2+)-activated K(+) channel KCa3.1 compartmentalizes in the immunological synapse of human T lymphocytes.

T cell receptor engagement results in the reorganization of intracellular and membrane proteins at the T cell-antigen presenting cell interface forming the immunological synapse (IS), an event required for Ca(2+) influx. KCa3.1 channels modulate Ca(2+) signaling in activated T cells by regulating the membrane potential.
