N-Benzoyl-N′,N′-dimethyl­thio­urea

In the title compound, C10H12N2OS, the amide NCO group is twisted relative to the thio­ureido SCN2 group, forming a dihedral angle of 55.3 (2)°. The crystal packing shows inter­molecular N—H⋯S and weak C—H⋯O inter­actions, the former giving rise to the formation of centrosymmetric R 2 2(8) dimers

Modeling iPSC-derived human neurofibroma-like tumors in mice uncovers the heterogeneity of Schwann cells within plexiform neurofibromas

Fibroblast; Neural crest; SpheroidsFibroblasto; Cresta neural; EsferoidesFibroblast; Cresta neural; EsferoidesPlexiform neurofibromas (pNFs) are developmental tumors that appear in neurofibromatosis type 1 individuals, constituting a major source of morbidity and potentially transforming into a highly metastatic sarcoma (MPNST). pNFs arise after NF1 inactivation in a cell of the neural crest (NC)-Schwann cell (SC) lineage. Here, we develop an iPSC-based NC-SC in vitro differentiation system and construct a lineage expression roadmap for the analysis of different 2D and 3D NF models. The best model consists of generating heterotypic spheroids (neurofibromaspheres) composed of iPSC-derived differentiating NF1(−/−) SCs and NF1(+/−) pNF-derived fibroblasts (Fbs). Neurofibromaspheres form by maintaining highly proliferative NF1(−/−) cells committed to the NC-SC axis due to SC-SC and SC-Fb interactions, resulting in SC linage cells at different maturation points. Upon engraftment on the mouse sciatic nerve, neurofibromaspheres consistently generate human NF-like tumors. Analysis of expression roadmap genes in human pNF single-cell RNA-seq data uncovers the presence of SC subpopulations at distinct differentiation states.This work has mainly been supported by an agreement from the Johns Hopkins University School of Medicine and the Neurofibromatosis Therapeutic Acceleration Program (NTAP).

1-Furoyl-3-methyl-3-phenyl­thio­urea

The title compound, C13H12N2O2S, crystallizes with two independent mol­ecules in the asymmetric unit. The two mol­ecules differ in the conformation of the thio­carbonyl and carbonyl groups, and show the typical geometric parameters of substituted thio­urea derivatives. The crystal structure is mainly stabilized by inter­molecular N—H⋯O hydrogen bonding

Tris(N-benzoyl-N′,N′-diphenyl­thio­ureato-κ2 O,S)cobalt(III)

In the title compound, [Co(C20H15N2OS)3], the CoIII atom is coordinated by the S and O atoms of three N-benzoyl-N′,N′-diphenyl­thio­urea ligands in a slightly distorted octa­hedral geometry. The O and S atoms are in cis positions, while the positions between the O and S atoms are trans

Weight-loss practices among university students in Mexico

To evaluate the prevalence of weight-loss practices among university students from Tlaxcala, Mexico. A cross-sectional study of 2,651 university students was conducted. Logistic regression tests were used to estimate the probability of students trying to lose weight and successfully achieving weight loss. Nearly 40% of students attempted to lose weight, though only about 7% lost more than 10% of their body weight and maintained this weight loss during the time of the study. The methods used most were exercise and dieting, and those who dieted were more successful at losing weight. The high prevalence of weight-loss attempts and the poor outcomes with these weight-loss methods among this sample of university students is a public health concern. Universities should provide students with healthy weight-control approaches, which include offering information about healthier lifestyles, access to healthy food and opportunities to be physically active

1-(3-Cyano­phen­yl)-3-(2-furo­yl)thio­urea

The title compound, C13H9N3O2S, was synthesized from furoyl isothio­cyanate and 3-amino­benzonitrile in dry acetone. The thio­urea group is in the thio­amide form. The thio­urea fragment makes dihedral angles of 3.91 (16) and 37.83 (12)° with the ketofuran group and the benzene ring, respectively. The mol­ecular geometry is stabilized by N—H⋯O hydrogen bonds. In the crystal structure, centrosymmetrically related mol­ecules are linked by two inter­molecular N—H⋯S hydrogen bonds to form dimers

1-Benzyl-3-(2-furo­yl)thio­urea

In the title compound, C13H12N2O2S, the dihedral angle between the two aromatic ring planes is 87.52 (12)°. The mol­ecule shows an intra­molecular N—H⋯O hydrogen bond. The crystal structure is stabilized by inter­molecular N—H⋯S and C—H⋯O hydrogen bonding

Gestión de destinos familiares a través de la gamificación y personalización de viajes en familia en tiempo real

This paper presents a digital development designed specifically for family tourism with the creation of applications named Costa Daurada Trip&Kids and Terres de l’Ebre Trip&Kids. Its objectives are: 1) to facilitate, through an intelligent system, family tourism experiences to certain tourist attractions, especially beaches, cultural heritage and wine culture, and 2) to improve the experience of families during the visit to the attractions and increase their loyalty degree. These applications use intelligent systems to suggest to families the experiences that best suit their needs (such as children's age, interests, means of transport, etc.), considering the affluences, booking availability, parking options, opening hours or weather forecast, among others, in real time, of the attractions and their surroundings. The applications use gamification tools to enable the collection of user data, as well as to encourage visits to other areas with less popularity and help alleviate overcrowding in most frequented ones. Finally, indicators for tourism destination managers are generated through monitoring the behaviour of users with the applications.En este artículo se presenta un desarrollo tecnológico diseñado específicamente para el turismo familiar que se materializa en las aplicaciones Costa Daurada Trip&Kids y Terres de l’Ebre Trip&Kids. Sus objetivos son: 1) facilitar a través de un sistema de gestión inteligente las visitas de turismo familiar hacia determinados atractivos turísticos, en especial los relacionados con las playas, el patrimonio cultural y la cultura del vino, y 2) mejorar la experiencia de las familias durante la visita a los atractivos e incrementar su grado de fidelización. Las aplicaciones utilizan sistemas inteligentes para sugerir a las familias las experiencias que mejor se ajustan a sus necesidades (edad de los niños, intereses, medio de transporte, etc.), teniendo en cuenta la afluencia, la posibilidad de reservar, las opciones de aparcamiento, los horarios o la meteorología, entre otros, en tiempo real, de los atractivos y su entorno. Las aplicaciones utilizan herramientas de gamificación para posibilitar la recogida de datos de los usuarios, así como también para incentivar las visitas a otras zonas con menor afluencia y descongestionar las zonas más frecuentadas. Finalmente, se generan indicadores para los gestores de destinos turísticos a través de la monitorización del comportamiento de los usuarios con las aplicaciones

Immunogenicity and protection against Mycobacterium caprae challenge in goats vaccinated with BCG and revaccinated after one year

Vaccination has been proposed as a supplementary tool for the control of tuberculosis in livestock. The long-term immunogenicity elicited by bacillus Calmette-Guerin (BCG) and the efficacy of revaccination were investigated in thirty goat kids distributed into three groups: unvaccinated controls, BCG (vaccinated at week 0) and BCG-BCG (vaccinated at weeks 0 and 56). Sixty-four weeks after the first vaccination, all animals were challenged with Mycobacterium caprae and examined post-mortem (pathology and bacterial load) at week 73. Antigen-specific interferon-gamma (IFN-γ) release was measured throughout the experiment. At week 59, peripheral blood mononuclear cells were stained for CD4, CD45RO and IFN-γ to determine the presence of antigen-specific cells secreting IFN-γ. The BCG-BCG group showed reductions in rectal temperatures, M. caprae DNA load in pulmonary lymph nodes (LN), the volume of lesions in pulmonary LN, mineralization in lungs, and higher weight gains compared to unvaccinated controls. IFN-γ responses were undetectable from 32 weeks after primary vaccination until revaccination, when the BCG-BCG group showed detectable IFN-γ production and a greater percentage of antigen-specific CD4+CD45RO+IFNγ+ and CD4-CD45RO+IFNγ+ cells compared to the BCG and control groups, which may be an indicator of the mechanisms of protection. Thus, re-vaccination of goats with BCG appears to prolong protection against infection with M. caprae.info:eu-repo/semantics/publishedVersio
