BACKGROUND: Type 1 diabetes mellitus described as a chronic metabolic disorder characterized by aggressive immune β-cell destruction. There are numbers of varied immune mechanisms for sustaining self-tolerance in opposition to the autoimmune disorders. A recessive tolerance accomplished by thymic gland via a negative assortment of different clones while a dominant tolerance accomplished by the regulatory T cells (Treg) in the periphery. Treg (CD4+CD25+FOXP3+) are subsets of T cells which have an essential role in maintaining tolerance...

BACKGROUND: Body-focused repetitive behaviors (BFRBs), such as hair pulling, skin picking, and nail biting, are repetitive, destructive, and nonfunctional habits that cause significant distress. Separate BFRBs form a cohesive group and could be assessed as part of the Tourette/tic spectrum or obsessive-compulsive spectrum of disorders. The treatment of choice is either antidepressant or behavioral treatment, both of which have shown effectiveness. The cognitive psychophysiological (CoPs) model focuses on the tension and emotional build up that triggers habits by addressing cognitive-behavioral, emotional and psychophysiological processes preceding onset rather than the habit itself...

OBJECTIVES: This study examined parental perceptions of behaviours that challenge (CB) in their adult children with intellectual disability (ID), and explored whether perceptions mediated associations between CB and parental psychological distress. DESIGN: A within-group correlational design was employed. METHODS: Sixty-five parents reported on individuals with genetic syndromes and ID who had chronic CB. Parents completed the Illness Perception Questionnaire-Revised (IPQ-R) adapted to measure perceptions of self-injury, aggression or property destruction, alongside assessments of parental locus of control, attributions about behaviour, parental psychological distress, and CB...

Transient electronics are becoming a hot topic due to the rapid development of bioelectronics, self-destructive devices and environmental sensors. This letter reports a novel scheme for triggering degradation of 250 μm-thick Mg target using acetic acid regarding transient electronics applications. The triggered transience has also been demonstrated using commercial vinegar. To achieve programmable transience as well as device protection, polypropylene carbonate (PPC) was investigated as passivation layer. The proposed method has demonstrated simplicity, high safety, low cost and low trigger temperature...

Early childhood caries (ECC) is major oral health problem, mainly in socially disadvantaged populations. ECC affects infants and preschool children worldwide. The prevalence of ECC differs according to the group examined, and a prevalence of up to 85% has been reported for disadvantaged groups. ECC is the presence of one or more decayed, missing, or filled primary teeth in children aged 71 months (5 years) or younger. It begins with white-spot lesions in the upper primary incisors along the margin of the gingiva...

Diabetes results from an inadequate mass of functional beta cells, due to either beta cell loss caused by autoimmune destruction (Type I diabetes) or beta cell failure in response to insulin resistance (Type II diabetes). Elucidating the mechanisms that regulate beta cell mass may be key to developing new techniques that foster beta cell regeneration as a cellular therapy to treat diabetes. While previous studies concluded that cyclin D2 is required for postnatal beta cell self-renewal in mice, it is not clear if cyclin D2 is sufficient to drive beta cell self-renewal...

Alberto Pugliese
Type 1 diabetes (T1D) is a chronic autoimmune disease that causes severe loss of pancreatic β cells. Autoreactive T cells are key mediators of β cell destruction. Studies of organ donors with T1D that have examined T cells in pancreas, the diabetogenic insulitis lesion, and lymphoid tissues have revealed a broad repertoire of target antigens and T cell receptor (TCR) usage, with initial evidence of public TCR sequences that are shared by individuals with T1D. Neoepitopes derived from post-translational modifications of native antigens are emerging as novel targets that are more likely to evade self-tolerance...

This volume of Periodontology 2000 represents the 25th anniversary of the Journal, and uses the occasion to assess important advancements in periodontology over the past quarter-century as well as the hurdles that remain. Periodontitis is defined by pathologic loss of the periodontal ligament and alveolar bone. The disease involves complex dynamic interactions among active herpesviruses, specific bacterial pathogens and destructive immune responses. Periodontal diagnostics is currently based on clinical rather than etiologic criteria, and provides limited therapeutic guidance...

This article outlines the ultrasound data employed to calibrate in the laboratory an analytical model that permits the calculation of the depth of partial-depth surface-initiated cracks on bituminous pavements using this non-destructive technique. This initial calibration is required so that the model provides sufficient precision during practical application. The ultrasonic pulse transit times were measured on beam samples of different asphalt mixtures (semi-dense asphalt concrete AC-S; asphalt concrete for very thin layers BBTM; and porous asphalt PA)...

Anger is a significant human emotion with far-reaching implications for individuals and relationships. We propose a transactional model of anger that highlights its relational relevance and potentially positive function, in addition to problematic malformations. By evolutionary design, physical, self-concept, or attachment threats all similarly trigger diffuse physiological arousal, psychologically experienced as anger-emotion. Anger is first a signaling and motivational system. Anger is then formed to affirming, productive use or malformed to destructive ends...

BACKGROUND: Development of a better understanding of subsequent pathways for individuals who experienced trauma during childhood might usefully inform clinicians and public health professionals regarding the causes of self-harm and interpersonal violence. We aimed to examine these risks during late adolescence and early adulthood among people admitted to hospital following injuries or poisonings during their childhood. METHODS: This national cohort study included Danish people born between Jan 1, 1977, and Dec 31, 1997, and was linked to the National Patient Register and Psychiatric Central Research Register to identify all people exposed to hospital admissions for injuries or poisonings due to self-harm, interpersonal violence, or accidents before their 15th birthday...

The transcription factor Tcf1 is essential for the development of natural killer (NK) cells. However, its precise role has not been clarified. Our combined analysis of Tcf1-deficient and transgenic mice indicated that Tcf1 guides NK cells through three stages of development. Tcf1 expression directed bone marrow progenitors toward the NK cell lineage and ensured the survival of NK-committed cells, and its downregulation was needed for terminal maturation. Impaired survival of NK-committed cells was due to excessive expression of granzyme B (GzmB) and other granzyme family members, which induced NK cell self-destruction during maturation and following activation with cytokines or target cells...

Abnormal uterine bleeding (AUB) is a common complaint that affects large numbers of women from puberty to menopause. It negatively affects health by causing anemia, and impacts the quality of life of women affected. AUB also has an economic impact for both women and society. Therefore, it should not be under- or overestimate and diagnosis, investigations and treatment should be proposed, taking into account the scientific data available in the current state of medical knowledge. Using the new terminology and etiologic classification of AUB is essential to communicate properly around the subject...

Severe toxicity and poor tumour penetration are two intrinsic limited factors to hinder the broad clinical application for most of first-line chemotherapeutics. In this study, a novel vitamin E succinate-grafted ε-polylysine (VES-g-PLL) polymer was synthesized by using ε-polylysine as backbone. By adjusting VES graft ratio, VES-g-PLL (50) with a theoretic VES graft ratio of 50% could self-assemble into a supermolecular micelle with a hydrodynamic diameter (Dh) of ca.20nm, and Zeta potential of 19.6mV. VES-g-PLL micelles themselves displayed a strong anti-tumour effect on glioma...

Virus-specific cluster of differentiation 8 (CD8+) cytotoxic T cells (CTL) recognize viral antigens presented on major histocompatibility complex (MHC) class I chains on infected hepatocytes, with help from CD4+ T cells. However, this CTL response is frequently weak or undetectable in patients with chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infection. Programmed cell death 1 (PD-1) and cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) are receptors in the CD28 family of costimulatory molecules, providing inhibitory signals to T cells...
