BACKGROUND: School-based treatment and counseling services (TCSs) can integrate mind-body techniques (MBTs) to improve children's health, wellness, and academic performance. We aimed to describe the effect of school-based TCS on MBT-use among students experiencing difficulties with concentration, emotions, behaviors, and getting along (DCEBG). METHODS: National Health Interview Survey data were utilized (N2007  = 1225; N2012  = 1835). Logistic regression examined associations between TCS-type and MBT-use, while propensity score matching controlled for confounders in the prematch sample...

OBJECTIVE: Tuberculosis (TB) is a zoonotic infectious disease common to humans and animals that is caused by the rod-shaped acid-fast bacterium Mycobacterium bovis. Rapid and sensitive detection of TB is promoted by specific antigens. Virulent strains of the TB complex from M. bovis contain 16 regions of difference (RD) in their genome that encode important proteins, including major protein of Mycobacterium Tuberculosis 64 (MBT-64, which is a primary immune-stimulating antigen encoded by RD-2...

A broad range of mind-body therapies (MBTs) are used by the public today, and a growing body of clinical and basic sciences research has resulted in evidence-based integration of many MBTs into clinical practice. Basic sciences research has identified some of the physiological correlates of MBT practices, leading to a better understanding of the processes by which emotional, cognitive and psychosocial factors can influence health outcomes and well-being. In particular, results from functional genomics and neuroimaging describe some of the processes involved in the mind-body connection and how these can influence health outcomes...

Species identification and drug susceptibility testing (DST) of mycobacteria is an important yet complex process, traditionally reserved for reference laboratories. Recent technical improvements in MALDI-TOF MS started to facilitate routine mycobacterial identifications in clinical laboratories. In this paper, we investigate the possibility to perform phenotypic MALDI-based DST in mycobacteriology, using the recently described MALDI Biotyper antibiotic susceptibility test rapid assay (MBT-ASTRA™). We randomly selected 72 clinical M...

Revealing the stability and structural patterns is important for precisely synthesizing or assembling ligand protected nanoclusters, and even their applications as functional nanomaterials. Investigations on structural evolutional patterns and structural stability are very challenging, because structures change with the nanocluster size and the structural stability depends on both the electron structures of cores and ligand type. Herein, we propose a hybrid superatom network (hSAN) model to understand the stability of some gold nanoclusters with different kinds of ligands...

A critical step in proteomic analyses comprises the implementation of a reliable cell lysis method with high yields of qualitative proteins. In Mycobacteria, the protein extraction step is often hampered by the thick waxy cell wall which is rich in mycolic acids. Harsh disruption techniques to release proteins from the cells are thus required. Here, we demonstrate an optimized protein extraction procedure for Mycobacterium tuberculosis (Mbt) that results in protein extracts that are useful for all currently used proteomics platforms, including gel and LC-MS based strategies...

Following fertilization, vertebrate embryos delay large-scale activation of the zygotic genome from several hours in fish and amphibians to several days in mammals. Externally developing embryos also undergo synchronous and extraordinarily rapid cell divisions that are accelerated by promiscuous licensing of DNA replication origins, absence of gap phases and cell cycle checkpoints, and preloading of the egg with maternal RNAs and proteins needed to drive early development. After a species-specific number of cell divisions, the cell cycle slows and becomes asynchronous, gap phases appear, checkpoint functions are acquired, and large-scale zygotic gene activation begins...

Compliance and patience is needed when meeting patients with personality disorder To encounter patients with personality disorders in health care settings is often challenging. Most treatment studies published have included only patients with borderline personality disorder. Of evaluated psychological treatments in borderline personality disorder, dialectical behaviour therapy (DBT) has the strongest research support, followed by mentalization based therapy (MBT). Pharmacological treatment in personality disorders should focus on time-limited crisis intervention and treatment of comorbidity...

The German Human Biomonitoring Commission (HBM Commission) derives health-related guidance values (Human Biomonitoring assessment values, HBM values) according to the procedures described in the HBM Commission's position papers. Since the last adaption of the methodology in 2014, the HBM Commission has established a series of new HBM values, mainly on the basis of internationally agreed TDI/RfD values, or of toxicologically well- founded points of departure observed in animal studies. The derivation of these new HBM values for HBCDD, triclosan, 2-MBT, PFOA and PFOS as well as for the metabolites of glycol ethers, of Hexamoll(®) DINCH(®), DPHP, DEHTP, NMP, NEP, and 4-MBC is specified, and the HBM values are presented together with already established HBM values for other substances...

Wnt/β-catenin signaling is essential for the initiation of dorsal-ventral patterning during vertebrate embryogenesis. Maternal β-catenin accumulates in dorsal marginal nuclei during cleavage stages, but its critical target genes essential for dorsalization are silent until mid-blastula transition (MBT). Here, we find that zebrafish net1, a guanine nucleotide exchange factor, is specifically expressed in dorsal marginal blastomeres after MBT, and acts as a zygotic factor to promote the specification of dorsal cell fates...

Proponents of the now half-dozen major psychotherapeutic approaches tend to claim the superiority of their different approaches-known widely by their acronyms: CBT for Cognitive Behavioral Therapy, DBT for Dialectic Behavioral Therapy, MBT for Mentalization-Based Therapy, TFP for Transference- Focused Psychotherapy, and so on. The data thus far support the utility of each method, but do not show clear-cut superiority of any one method. A large percentage of BPD patients eventually improve or even recover, but these favorable results appear to derive from a multiplicity of factors...

OBJECTIVES: Borderline personality disorder (BPD) is characterized by emotional instability, interpersonal dysfunction, and other features that typically develop before a background of insecure attachment and traumatic experiences. Dialectical behaviour therapy (DBT) has proven highly effective in reducing self-harm and improving emotion regulation, whereby problems concerning social cognition, which are also characteristic of BPD, may need additional approaches such as mentalization-based treatment (MBT)...

During embryogenesis, the initial chromatin state is established during a period of rapid proliferative activity. We have measured with 3-min time resolution how heritable patterns of chromatin structure are initially established and maintained during the midblastula transition (MBT). We find that regions of accessibility are established sequentially, where enhancers are opened in advance of promoters and insulators. These open states are stably maintained in highly condensed mitotic chromatin to ensure faithful inheritance of prior accessibility status across cell divisions...

Optimal hemodynamics in aorta-pulmonary shunt reconstruction is essential for improved post-operative recovery of the newborn congenital heart disease patient. However, prior to in vivo execution, the prediction of post-operative hemodynamics is extremely challenging due to the interplay of multiple confounding physiological factors. It is hypothesized that the post-operative performance of the surgical shunt can be predicted through computational blood flow simulations that consider patient size, shunt configuration, cardiac output and the complex three-dimensional disease anatomy...

Despite their ban on small vessels in 1989 in the EU, organotin compounds (OTCs) are still being released into the environment due to their presence in historic paint layers on leisure boats. 23 paint samples scraped from recreational boats from three countries around the Baltic Sea were analyzed for total tin (Sn) and OTCs. Two antifouling paint products were also subjected to the same analyses. A new method for the detection of Sn in paint flake samples was developed and found to yield more accurate results compared to four different acid digestion methods...
