[Family relations and behavioral-emotional problems in adolescents - an analysis with the adolescent version of the Family Relations Test for Children and Adolescents].

Unlabelled: Family relations and behavioral-emotional problems in adolescents - an analysis with the adolescent version of the Family Relations Test for Children and Adolescents Abstract.

Objectives: So far hardly any instruments are available for the German-speaking countries, covering family relations from the perspective of young people reliably. Moreover, the relationship between family relations from the perspective of young people and behavioral problems has been rarely investigated.

Daily Moderate Exercise Is Beneficial and Social Stress Is Detrimental to Disease Pathology in Murine Lupus Nephritis.

Daily moderate exercise (DME) and stress management are underemphasized in the care of patients with lupus nephritis (LN) due to a poor comprehensive understanding of their potential roles in controlling the inflammatory response. To investigate these effects on murine LN, disease progression was monitored with either DME or social disruption stress (SDR) induction in NZM2410/J mice, which spontaneously develop severe, early-onset LN. SDR of previously established social hierarchies was performed daily for 6 days and DME consisted of treadmill walking (8.

Estrogen-regulated STAT1 activation promotes TLR8 expression to facilitate signaling via microRNA-21 in systemic lupus erythematosus.

Recent studies implicate innate immunity to systemic lupus erythematosus (SLE) pathogenesis. Toll-like receptor (TLR)8 is estrogen-regulated and binds viral ssRNA to stimulate innate immune responses, but recent work indicates that microRNA (miR)-21 within extracellular vesicles (EVs) can also trigger this receptor. Our objective was to examine TLR8 expression/activation to better understand sex-biased responses involving TLR8 in SLE.

A chimeric human-mouse model of Sjögren's syndrome.

Despite recent advances in the understanding of Sjögren's Syndrome (SjS), the pathogenic mechanisms remain elusive and an ideal model for early drug discovery is not yet available. To establish a humanized mouse model of SjS, peripheral blood mononuclear cells (PBMCs) from healthy volunteers or patients with SjS were transferred into immunodeficient NOD-scid IL-2rγ(null) mouse recipients to produce chimeric mice. While no difference was observed in the distribution of cells, chimeric mice transferred with PBMCs from SjS patients produced enhanced cytokine levels, most significantly IFN-γ and IL-10.

Oral administration of nano-emulsion curcumin in mice suppresses inflammatory-induced NFκB signaling and macrophage migration.

Despite the widespread use of curcumin for centuries in Eastern medicine as an anti-inflammatory agent, its molecular actions and therapeutic viability have only recently been explored. While curcumin does have potential therapeutic efficacy, both solubility and bioavailability must be improved before it can be more successfully translated to clinical care. We have previously reported a novel formulation of nano-emulsion curcumin (NEC) that achieves significantly greater plasma concentrations in mice after oral administration.

Desnutrin/ATGL is regulated by AMPK and is required for a brown adipose phenotype.

While fatty acids (FAs) released by white adipose tissue (WAT) provide energy for other organs, lipolysis is also critical in brown adipose tissue (BAT), generating FAs for oxidation and UCP-1 activation for thermogenesis. Here we show that adipose-specific ablation of desnutrin/ATGL in mice converts BAT to a WAT-like tissue. These mice exhibit severely impaired thermogenesis with increased expression of WAT-enriched genes but decreased BAT genes, including UCP-1 with lower PPARα binding to its promoter, revealing the requirement of desnutrin-catalyzed lipolysis for maintaining a BAT phenotype.

Differences between human wild-type and C23S variant 5-HT2C receptors in inverse agonist-induced resensitization.

The aim of this study was to analyze functional properties of the naturally occurring C23S variant of the human 5-HT2C receptor. In HEK293 cells transiently expressing the unedited forms of the variant receptor (VR) or the wild-type receptor (WTR), surface expression was determined by [3H]mesulergine binding to membrane fragments. Function was examined by an aequorin luminescence-based Ca2+ assay.

Serotonin receptor diversity in the human colon: Expression of serotonin type 3 receptor subunits 5-HT3C, 5-HT3D, and 5-HT3E.

Since the first description of 5-HT₃ receptors more than 50 years ago, there has been speculation about the molecular basis of their receptor heterogeneity. We have cloned the genes encoding novel 5-HT3 subunits 5-HT3C, 5-HT3D, and 5-HT3E and have shown that these subunits are able to form functional heteromeric receptors when coexpressed with the 5-HT3A subunit. However, whether these subunits are actually expressed in human tissue remained to be confirmed.

Phosphodiesterase 4B is essential for T(H)2-cell function and development of airway hyperresponsiveness in allergic asthma.

Background: Cyclic AMP (cAMP) signaling modulates functions of inflammatory cells involved in the pathogenesis of asthma, and type 4 cAMP-specific phosphodiesterases (PDE4s) are essential components of this pathway. Induction of the PDE4 isoform PDE4B is necessary for Toll-like receptor signaling in monocytes and macrophages and is associated with T cell receptor/CD3 in T cells; however, its exact physiological function in the development of allergic asthma remains undefined.

Objectives: We investigated the role of PDE4B in the development of allergen-induced airway hyperresponsiveness (AHR) and T(H)2-driven inflammatory responses.

RIC-3 exclusively enhances the surface expression of human homomeric 5-hydroxytryptamine type 3A (5-HT3A) receptors despite direct interactions with 5-HT3A, -C, -D, and -E subunits.

Although five 5-hydroxytryptamine type 3 (5-HT3) subunits (A-E) have been cloned, knowledge on the regulation of their assembly is limited. RIC-3 has been identified as a chaperone specific for the pentameric ligand-gated nicotinic acetylcholine and 5-HT(3) receptors. Therefore, we examined the impact of RIC-3 on differently composed 5-HT(3) receptors with the focus on 5-HT3C, -D, and -E subunits.

Thyroidal radioactive iodide uptake in the lactating rhesus monkey.

Although radioactive iodide uptake (RAIU) is one of the reliable diagnostic methods for thyroid function in adult humans, especially in the diagnosis of thyrotoxicosis, there are limited data for RAIU during pregnancy and lactation in humans and animals. Therefore, we proposed to validate RAIU for the lactating rhesus monkey to further human model studies in thyroid disease. RAIU was performed at 6 and 24 h using 100 microCi of (123)I orally in four lactating monkeys.

Characterization of the naturally occurring Arg344His variant of the human 5-HT 3A receptor.

The present study aimed at examining the function and pharmacological properties of the naturally occurring Arg344His variant of the human 5-HT(3A) receptor, identified in a schizophrenic patient. In intact human embryonic kidney (HEK) 293 cells expressing the wild-type (WT) or the variant receptor, the function was analyzed by indirect measurement of agonist-induced Ca(2+) current through the 5-HT(3A) receptor channel by an aequorin luminescence-based Ca(2+) assay. In cell membrane patches cation currents were determined electrophysiologically including technically demanding single channel analyses.

Animals: 18 healthy adult horses.

Procedures: Horses were randomly assigned to 3 groups (n = 6 horses/group) and administered an IV infusion of 30 ng of endotoxin/kg or saline (0.

Childhood obesity prevention: an intervention targeting primary caregivers of school children.

Community-based participatory research (CBPR) was used to design and evaluate the effectiveness of a culturally relevant, science-based intervention for the prevention of childhood obesity in the Commonwealth of the Northern Mariana Islands (CNMI), a US Commonwealth in the western Pacific. This cognitive behavioral lifestyle intervention, Project Familia Giya Marianas (PFGM), was offered during the 2005-2007 school years in all CNMI public elementary schools over eight sessions to primary caregivers of 3rd grade children (N = 407). A crossover design was utilized with half of the schools offering the intervention in the Fall term, while the other half delivered the sessions in the Spring term.

Association of major depression with rare functional variants in norepinephrine transporter and serotonin1A receptor genes.

Dysregulations of central noradrenergic and serotonergic neurotransmission have been suggested to contribute to the pathogenesis of neuropsychiatric disorders such as depression. The norepinephrine transporter (NET; SLC6A2) and the serotonin (5-HT)(1A) receptor (5-HT(1A) receptor; HTR1A) play an important role in central nervous monoaminergic homeostasis. As shown previously, variations in the human NET and 5-HT(1A) receptor genes can alter noradrenergic and serotonergic signaling in the brain: a single nucleotide polymorphism (SNP) in the coding region of the NET gene resulting in a F528C substitution increased plasma membrane expression of this NET variant, and a SNP in the human 5-HT(1A) receptor gene leading to the R219L receptor variant almost abolished cellular signal transduction subsequent to receptor activation.
