WNT/CTNNB1 signaling regulates tissue development and homeostasis in all multicellular animals, but the underlying molecular mechanism remains incompletely understood. Specifically, quantitative insight into endogenous protein behavior is missing. Here, we combine CRISPR/Cas9-mediated genome editing and quantitative live-cell microscopy to measure the dynamics, diffusion characteristics and absolute concentrations of fluorescently tagged, endogenous CTNNB1 in human cells under both physiological and oncogenic conditions. State-of-the-art imaging reveals that a substantial fraction of CTNNB1 resides in slow-diffusing cytoplasmic complexes, irrespective of the activation status of the pathway. This cytoplasmic CTNNB1 complex undergoes a major reduction in size when WNT/CTNNB1 is (hyper)activated. Based on our biophysical measurements, we build a computational model of WNT/CTNNB1 signaling. Our integrated experimental and computational approach reveals that WNT pathway activation regulates the dynamic distribution of free and complexed CTNNB1 across different subcellular compartments through three regulatory nodes the destruction complex, nucleocytoplasmic shuttling, and nuclear retention.The precise structural solution of crystals on a mesostructural scale is challenging due to the difficulties in obtaining electron diffraction and the complicated relationship between the crystal structure factors (CSFs) and the conventional underfocus phase-contrast transmission electron microscopy (TEM) images due to the large unit cell and the complex structures. Here, we present the structural investigation of mesostructured crystals via the combination of electron crystallographic Fourier synthesis and high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) that only relies on the mass-thickness contrast. The three-dimensional electrostatic potential is reconstructed from the amplitudes and phases extracted from the Fourier transforms of the corresponding HAADF-STEM images and merged into a set of CSFs. This method is verified on silica scaffolds following a shifted double-diamond surface network with space group I41/amd. The results indicate that electron crystallography reconstruction by HAADF-STEM images is more suitable and accurate in determining the structure in comparison with conventional TEM electron crystallography reconstruction. This approach transfers the contrast of mesostructured crystals to images more accurately and the relationship between the Fourier transforms of HAADF-STEM images and the CSFs is more intuitive. It shows great advantages for the structural solution of crystals on the mesostructural scale.
Gender disparities between Emergency Medicine physicians with regards to salary, promotion, and scholarly recognition as national conference speakers have been well-documented. However, little is known if similar gender disparities impact their out-of-hospital Emergency Medical Services (EMS) colleagues. Although there have been improvements in the ratio of women entering the EMS workforce, gender representation has improved at a slower rate for paramedics compared to emergency medical technicians (EMTs). Since recruitment, retention, and advancement of females within a specialty have been associated with the visibility of prominent, respected female leaders, gender disparity of these leaders as national conference speakers may contribute to the "leaky pipeline effect" seen within the EMS profession. Gender representation of these speakers has yet to be described objectively.
The primary objective of this study was to determine if disparity exists in gender representation of speakers at well-known nationaives, may reduce barriers to facilitating a new pipeline for more females to become speakers at national EMS conferences.
Terrorist attacks are growing in complexity, increasing concerns around the use of chemical, biological, radiation, and nuclear (CBRN) agents. This has led to increasing interest in Counter-Terrorism Medicine (CTM) as a Disaster Medicine (DM) sub-specialty. This study aims to provide the epidemiology of CBRN use in terrorism, to detail specific agents used, and to develop training programs for responders.
The open-source Global Terrorism Database (GTD) was searched for all CBRN attacks from January 1, 1970 through December 31, 2018. Attacks were included if they fulfilled the terrorism-related criteria as set by the GTD's Codebook. Ambiguous events or those meeting only partial criteria were excluded. The database does not include acts of state terrorism.
There were 390 total CBRN incidents, causing 930 total fatal injuries (FI) and 14,167 total non-fatal injuries (NFI). A total of 347 chemical attacks (88.9% of total) caused 921 FI (99.0%) and 13,361 NFI (94.3%). Thirty-one biological attacks (8.0%) ca given the rising rate of terrorist events. Counter-Terrorism Medicine is a developing DM sub-specialty focusing on the mitigation of health care risks from such events. First responders and health care workers should be aware of historic use of CBRN weapons regionally and globally, and should train and prepare to respond appropriately.
Currently, CBRN are low-frequency, high-impact attack modalities and remain a concern given the rising rate of terrorist events. Counter-Terrorism Medicine is a developing DM sub-specialty focusing on the mitigation of health care risks from such events. First responders and health care workers should be aware of historic use of CBRN weapons regionally and globally, and should train and prepare to respond appropriately.In the bean crop there are limited options of herbicides to control eudicotyledons weeds in pre-emergence and sulfentrazone presents potential to be used in a weed management program. Repertaxin solubility dmso The aim of this study was to determine the tolerance of a large number of Brazilian bean genotypes to sulfentrazone and their relation with morphophysiological characteristics, associating it to market classes, seed size and their center of origin. It was evaluated the effect of sulfentrazone application (400 g a.i. ha-1) in pre-emergence of 40 Brazilian bean genotypes, 36 of which were common-bean (Phaseolus vulgaris), two cowpeas (Vigna unguiculata), one adzuki bean (Vigna angularis) and one mung bean (Vigna radiata). There was high tolerance variation of the genotypes to sulfentrazone. Morphological parameters were strongly related with relative tolerance. Common bean genotypes that had medium to large seed size (cranberry and carioca) were more tolerant, while small-sized seed genotypes were more sensitive (black). Andean genotypes were more tolerant than Mesoamerican genotypes.
