Self-assembly of perylene derivative such as N,N'-bis(2(trimethylammonium iodide) ethylene)perylene-3,4,9,10-tetracarboxyldiimide (TAIPDI) can produce one-dimensional form (1D) in an aqueous media. The ability of one-dimensional TAIPDI to form light harvesting complex with water-soluble zinc porphyrin (ZnTPPS4) via the π-π and electrostatic interactions has been described. Owing to electronic interactions between the π-systems, the complex formation is accompanied by pronounced absorption spectral changes in the UV/Vis absorption bands...

Two herds of dromedary camels were longitudinally sampled with nasal and rectal swabs and serum, between September 2014 and May 2015, and the samples were tested for Middle East Respiratory Syndrome (MERS) coronavirus RNA and antibodies. Evidence of MERS-CoV infection was confirmed in one herd on the basis of detection of virus RNA in nasal swabs from three camels and significant increases in the antibody titers from three others. The three viruses were genetically identical, thus indicating introduction of a single virus into this herd...

Intensive glycemic control (IGC) targeting HbA1c fails to show an unequivocal reduction of macrovascular complications in type 2 diabetes (T2D), however the underlining mechanisms remain elusive. Epigenetic changes are emerging as important mediators of cardiovascular damage and may play a role in this setting. This study investigates whether epigenetic regulation of the adaptor protein p66(Shc), a key driver of mitochondrial oxidative stress, contributes to persistent vascular dysfunction in T2D patients despite IGC...

A teacher is a social referent for peer liking and disliking when students adjust their evaluations of a peer based on their perceptions of teacher liking and disliking for this peer. The present study investigated social referencing as an intra-individual process that occurs over time, using stochastic actor-oriented modeling with RSiena. The co-evolution of peer-perceived teacher liking and disliking networks with peer liking and disliking networks was analyzed in 52 fifth-grade classes in the Netherlands, with 1370 students (Mage=10...

Objectives: When adult children incur life problems (e.g., divorce, job loss, health problems), aging parents generally report providing more frequent support and experiencing poorer well-being. Yet, it is unclear how adult children's problems may influence aging parents' daily support exchanges with these children or the parents' daily mood. Methods: Aging parents from the Family Exchanges Study Wave 2 (N = 207, Mage = 79.86) reported providing and receiving emotional support, practical support, and advice from each adult child each day for 7 days...

OBJECTIVE: Neuropsychologists utilize performance validity tests (PVTs) as objective means for drawing inferences about performance validity. The Test of Memory Malingering (TOMM) is a well-validated, stand-alone PVT and the Reliable Digit Span (RDS) and Reliable Digit Span-Revised (RDS-R) from the Digit Span subtest of the WAIS-IV are commonly employed, embedded PVTs. While research has demonstrated the utility of these PVTs with various clinical samples, no research has investigated their use in adults with sickle cell disease (SCD), a condition associated with multiple neurological, physical, and psychiatric symptoms...

More knowledge is needed about men with sex chromosome aneuploidies (SCA). We present self-reported data from 53 men with SCA (Mage = 36.8 years, SD = 12.3, range 19-67). The Health Survey-Short Form (SF-36) measured eight health domains (physical functioning, role-physical, role-emotional, vitality, emotional health, social functioning, pain, general health). The Pittsburgh Sleep Quality Index measured sleep problems. The Personal Wellbeing Index measured satisfaction with eight life domains. Compared to norms, SCA reported poorer health (mean d = -0...

The expression of cancer-testis (CT) genes varies with tumor type. There are tumors with high, low, and intermediate gene expressions. Tumor cells of different origin are characterized by ST gene co-expression. The expression of ST genes increases in later stages of tumor development in the presence of metastases. In colon cancer, the tumor samples showed most frequently MAGE-A and SSX mRNA. The peripheral blood samples displayed most commonly XAGE, MAGE-C, and SSX mRNA. In patients with colon cancer, the expression of TSP50, MAGE-A(1-6), and SSX1,2,4 genes was associated with a poor prognosis, that of MAGE-C1 and XAGE1 was related to a favorable prognosis...

BACKGROUND: One of the main problems in the diagnostics of pediatric melanomas is the differentiation from benign dermal lesions typical for this age group, such as Spitz nevus. The biological behavior of pediatric melanomas differs considerably from that of melanomas in adults. MATERIAL AND METHODS: Cancer testis (CT) antigens are named after their typical expression pattern since they are present in various types of malignant tumors but in normal adult tissues are solely expressed in testicular germ cells...

The transtheoretical model of behavior change (TTM) is often used to understand changes in health-related behavior, like exercise. Exercise behavior in fitness clubs is an understudied topic, but preliminary studies showed low frequencies and large numbers of drop-out. An initial 12-week self-efficacy intervention reported significant effects on exercise behavior. The objective of this follow up study is testing effects on exercise behavior over 52 weeks and the long-term relationships of all TTM constructs...

OBJECTIVES: Night workers often experience high levels of sleepiness due to misalignment of the sleep-wake cycle from the circadian pacemaker, in addition to acute and chronic sleep loss. Exposure to light, in particular short wavelength light, can improve alertness and neurobehavioural performance. This randomised controlled trial examined the efficacy of blue-enriched polychromatic light to improve alertness and neurobehavioural performance in night workers. DESIGN: Participants were 71 night shift workers (42 males; 32...

While several studies have investigated maternal exposures as risk factors for oral clefts, few have examined paternal factors. We conducted an international multi-centered case-control study to better understand paternal risk exposures for oral clefts (cases = 392 and controls = 234). Participants were recruited from local hospitals and oral cleft repair surgical missions in Vietnam, the Philippines, Honduras, and Morocco. Questionnaires were administered to fathers and mothers separately to elicit risk factor and family history data...

Specific antitumor immunotherapy with autologous dendritic cell vaccines is one of the new approaches of modern medicine. For activation of dendritic cells highly immunogenic antigens are used, however optimal antigens in case of bladder cancer (BC) are still not researched. Cancer-testis antigens (CTA) are the most promising target in the context of creation of antitumor vaccines, because they are distinguished by pronounced immunogenicity, they are detected in different types of tumors and have limited pattern of expression in healthy tissues of grown-up organism...

Concomitant substance misuse in adults with borderline personality disorder (BPD) is associated with a more severe course of illness and poorer outcomes. Previous research has found an association between the number of borderline personality features and substance misuse in community samples. This study examined the relationship between substance use and severity of BPD in youth presenting for the first time for treatment (first presentation) of BPD. Participants were 117 help-seeking youth aged 15-25 years (93 females; Mage = 19...

To understand the conditions fostering positive outcomes of inclusive schooling, this two-wave study examined the role of individual change in trust and sympathy for adolescents' cross-group friendships and inclusive attitudes toward students with low academic achievement. Cross-group friendships, intergroup trust, intergroup sympathy, and inclusive attitudes were obtained from surveys completed by 1,122 Swiss adolescents (Mage T1  = 11.54 years, Mage T2  = 12.58 years) from 61 school classes. Results from a parallel latent change score model revealed that the number of cross-group friendships positively related to individual change in trust and sympathy; this growing trust and sympathy in turn predicted adolescents' inclusive attitudes...

This study examined how Greek and immigrant youth adapted to school life during the economic recession in Greece. Two cohorts of adolescents (Mage  = 12.6 years) were compared, one assessed before the crisis and the other during the crisis (N = 1,057 and 1,052, respectively). Cohort findings were disaggregated by immigrant status, generation, and ethnic group. Crisis-cohort youth experienced more economic problems, displayed worse conduct, higher levels of absenteeism, and lower self-efficacy than precrisis youth...

In Turkey, responsive behaviors toward kin are expected from children. Despite this, we know little about the factors that influence young Turkish children's prosocial behaviors. The goal was to explore how temperament and parenting are related to children's prosocial development in Turkey. A total of 293 Turkish children (Mage  = 49 months; 48.12% females) were followed up for 3 years. Mothers completed measures of their child's prosocial behaviors, as well as measures of their warmth, inductive reasoning, and the child's approach and reactivity...
