SecA is the ATPase of preprotein translocase. SecA is a dimer in solution and changes in its oligomeric state may function in preprotein translocation. The SecA-N68 construct, in which the C-terminal helical domains of SecA are deleted, was used to investigate the mechanism of SecA oligomerization. SecA-N68 is in equilibrium between monomers, dimers, and tetramers. Subunit interactions in the SecA-N68 tetramer are mediated entirely by unstructured regions at its N- and C-termini: when the termini are deleted to yield SecA-N68∆NC, the construct is completely monomeric...

Aqueous lithium energy storage systems address environmental sustainability and safety issues. However, significant capacity fading after repeated cycles of charge-discharge and during float charge limit their practical application compared to their nonaqueous counterparts. We introduce an artificial solid electrolyte interphase (SEI) to the aqueous systems and report the use of graphene films as an artificial SEI (G-SEI) that substantially enhance the overall performance of an aqueous lithium battery and a supercapacitor...

BACKGROUND: Although autopsy is a key component of the etiologic evaluation following fetal and early neonatal death, and traditionally has been the preferred method to determine the cause of death, an alternative may be suitable when traditional autopsy by a perinatal pathologist is not available or declined. METHODS: Among 3137 cases evaluated through the Wisconsin Stillbirth Service Program (WiSSP), a community-based program for etiologic evaluation of second trimester miscarriage, stillbirth, and early neonatal death, most diagnoses are based on multiple types of data including placental pathology, clinical examination, photographs, maternal records, radiographs, and laboratory testing...

In X-ray computed tomography (CT), the presence of metal objects in a patient's body produces streak artifacts in the reconstructed images. During the past decades, many different methods were proposed for the reduction or elimination of the streaking artifacts. When scanning a patient, the projection data affected by metal objects (missing projections) appear as regions with high intensities in the sinogram. In spiral fan beam CT, these regions are sinusoid-like curves on sinogram. During the first time, if the metal curves are detected carefully, then, they can be replaced by corresponding unaffected projections using other slices or opposite views; therefore, the CT slices regenerated by the modified sonogram will be imaged with high quality...

Bacterial adhesins are modular cell-surface proteins that mediate adherence to other cells, surfaces, and ligands. The Antarctic bacterium Marinomonas primoryensis uses a 1.5-MDa adhesin comprising over 130 domains to position it on ice at the top of the water column for better access to oxygen and nutrients. We have reconstructed this 0.6-μm-long adhesin using a "dissect and build" structural biology approach and have established complementary roles for its five distinct regions. Domains in region I (RI) tether the adhesin to the type I secretion machinery in the periplasm of the bacterium and pass it through the outer membrane...

The gut microbiota regulate susceptibility to multiple human diseases. The Nlrp6-ASC inflammasome is widely regarded as a hallmark host innate immune axis that shapes the gut microbiota composition. This notion stems from studies reporting dysbiosis in mice lacking these inflammasome components when compared with non-littermate wild-type animals. Here, we describe microbial analyses in inflammasome-deficient mice while minimizing non-genetic confounders using littermate-controlled Nlrp6-deficient mice and ex-germ-free littermate-controlled ASC-deficient mice that were all allowed to shape their gut microbiota naturally after birth...

INTRODUCTION: Bendamustine, typically in combination with rituximab, is an effective treatment for chronic lymphocytic leukemia (CLL) and B-cell non-Hodgkin lymphoma. Despite its acceptable short-term toxicity profile, long-term toxicities are less well established. This study investigated the long-term adverse effects of bendamustine and responses to subsequent treatments. PATIENTS AND METHODS: Charts of 194 patients were retrospectively reviewed; 54% had received prior treatment (76% attained complete response [CR] or partial response [PR])...

Stevia is a natural, non-nutritive sweetener can replace sugar in your diet to control diabetes and aid in weight loss. Naanberenji, an Iranian traditional cookie, is a well-reputed confectionary containing high sucrose and calorie value, for this reason its consumption in healthy diet has been restricted. In this study, the effect of sucrose replacement by stevioside-maltodextrin mixture on physicochemical properties of Naanberenji was evaluated in four replacing levels including 25%, 50%, 75%, and 100%. Results of texture evaluation revealed that hardness increases due to adding stevioside-maltodextrin (p < ...

Extensive Monte Carlo simulations were performed for (neon + krypton) mixtures for temperatures between 200 K and 600 K and pressures up to 1 GPa, using Lennard-Jones potentials to describe the intermolecular interactions. The residual entropies were obtained via Widom's insertion method, as well as via an integration technique. At high pressures, the residual entropy is, to a very good approximation, a linear function of λa(-1), which is the reciprocal value of the average Monte Carlo displacement parameter that gives the acceptance ratio a for translational moves...
