The coordinated temporal and spatial activation of gene expression is essential for proper stem cell differentiation. The Chromodomain Helicase DNA-binding protein 1 (CHD1) is a chromatin remodeler closely associated with transcription and nucleosome turnover downstream of the transcriptional start site (TSS). In this study, we show that CHD1 is required for the induction of osteoblast-specific...

Toxic shock syndrome (TSS) is a rare, life-threatening, acute multisystem illness usually characterized by sudden onset of high fever, diffuse sunburn-like erythroderma and a variety of other signs and symptoms. It may progress rapidly to hypotension and shock with multiple organ failure. Its exact cause is unknown, but in almost all cases there has been an infection with exotoxin-producing str...

Turnip crinkle virus contains a T-shaped, ribosome-binding, translation enhancer (TSS) in its 3'UTR that serves as a hub for interactions throughout the region. The viral RNA-dependent RNA polymerase (RdRp) causes the TSS/surrounding region to undergo a conformational shift postulated to inhibit translation. Using optical tweezers (OT) and steered molecular dynamic simulations (SMD), we found t...

The objective of this research was to modify an extended detention basin to provide batch treatment of stormwater runoff. An automated valve/controller was developed and placed on the outlet of a detention basin in Austin, Texas, which allowed the water quality volume to be retained in the basin for a preset length of time. The influent and effluent of the modified basin were monitored for tota...

BACKGROUND The NTI-tss device is an anterior bite stop, which, according to the manufacturer, is indicated for the prevention and treatment of bruxism, temporomandibular disorders (TMDs), tension-type headaches, and migraine. The aim of this systematic review was to appraise the currently available evidence regarding the efficacy and safety of the NTI-tss splint. METHODS We performed a system...

Little is known of the potential for biodegradation of fluorinated sulfonates. To evaluate this potential, the following model compounds were selected: difluoromethane sulfonate (DFMS), trifluoromethane sulfonate (TFMS), 2,2,2trifluoroethane sulfonate (TES), perfluorooctane sulfonate (PFOS), and 1H,1H,2H,2H-perfluorooctane sulfonate (H-PFOS). A laboratory isolate designated Pseudomonas sp. stra...

Computations on the reaction of azetidin-2-one, N-sulfonate azetidin-2-one, and 3-formylamine-N-sulfonate azetidin-2-one with [Mo(OH)(eta3-C3H5)(CO)2(N2C2H4)] were performed at the B3LYP/6-31+G(d,p) (LANL2DZ for Mo augmented by f polarization functions with exponents 1.043) taking into account solvent effects by means of the PCM-UAHF model. According to our calculations, the rate-determining en...

The primary objective of this paper is to describe the most common methods used to measure (i.e., sample and analyze) total suspended solids (TSS) and associated metals and phosphorus in urban runoff and to identify issues that may influence the accuracy of the results. This paper also discusses the availability of particle size distribution data from different developed and developing areas of...

2,4,6-Trichlorophenol (TCP) sulfonate esters undergo effective aminolysis under conventional heating and microwave irradiation; the reactivity of these species is such that chemoselective transformations of PFP sulfonate esters can be achieved.
