In this work, a turn on fluorescent sensor, based on Hg(2+) coordination conjugated polymer, was developed to detect cysteine-containing compounds. The fluorescence of conjugated polymer (poly(2,5-bis (sodium 4-oxybutyrate) -1,4 - phenylethynylene-alt-1,4-phenyleneethynylene; PPE-OBS) would be quenched by Hg(2+) because of the coordination-induced aggregation and electron transfers of PPE-OBS toward Hg(2+). When there were some cysteine-containing compounds in PPE-OBS-Hg(2+) system, the fluorescence of PPE-OBS would be recovered...

T-box transcription factors play key roles in the regulation of developmental processes such as cell differentiation and migration. Mammals have 17 T-box genes, of which several regulate brain development. The Tbr1 subfamily of T-box genes is particularly important in development of the cerebral cortex, olfactory bulbs (OBs), and cerebellum. This subfamily is comprised of Tbr1, Tbr2 (also known as Eomes), and Tbx21. In developing cerebral cortex, Tbr2 and Tbr1 are expressed during successive stages of differentiation in the pyramidal neuron lineage, from Tbr2+ intermediate progenitors to Tbr1+ postmitotic glutamatergic neurons...

Culture-based detection of nontyphoidal Salmonella spp. in foods requires at least four working days; therefore, new detection methods that shorten the test time are needed. In this study, we developed a novel single-step Salmonella enrichment broth, SSE-1, and compared its detection capability with that of commercial single-step ONE broth-Salmonella (OBS) medium and a conventional two-step enrichment method using buffered peptone water and Rappaport-Vassiliadis soy broth (BPW-RVS). Minimally processed lettuce samples were artificially inoculated with low levels of healthy and cold-injured Salmonella Enteritidis (10(0) or 10(1) colony-forming unit/25 g), incubated in OBS, BPW-RVS, and SSE-1 broths, and streaked on xylose lysine deoxycholate (XLD) agar...

Cysteine-rich 61 (CYR61/CCN1), a secreted protein in bone marrow (BM) microenvironment, has diverse effects on many cellular activities such as growth and differentiation. However, the effect of CCN1 on osteoblasts (OBs) in myeloma bone disease remains unclear. In our study, the level of CCN1 in multiple myeloma (MM) patients was detected by ELISA and RT-PCR. The proliferation and differentiation of OBs from MM patients were observed after stimulated by CCN1 in vitro. The myeloma cells transduced with CYR61 gene (RPMI‑8226/CYR61) were injected in a mouse model to evaluate the efficacy of CCN1 in vivo and compare with zoledronic acid...

Ferulic acid (FA) is an active component of the traditional Chinese herb Angelica sinensis. Numerous health benefits have been attributed to FA, but few studies have investigated the effects of FA on osteoblasts (Obs). Our work studied the effects of FA on proliferation, differentiation, and mineralization of rat calvarial Obs and examined the signaling pathways involved. Cell proliferation and differentiation were evaluated by Cell Counting Kit-8 (CCK-8) and alkaline phosphatase (ALP) assay kit, respectively...

We identified the neuro-protein CRMP4 (collapsing response mediator protein-4) as a non-canonical osteogenic factor that regulating the differentiation of mouse bone marrow skeletal stem cells (bone marrow stromal stem cells, mBMSCs) into osteoblastic cells. CRMP4 is the only member of the CRMP 1-5 family to be expressed by mBMSCs and in osteoprogenitors of both adult mouse and human bones. In vitro gain and loss function of CRMP4 in murine stromal cells revealed its inhibitory effect on osteoblast differentiation...

A procedure was developed to automatically generate auxiliary basis sets (ABSs) for use with the resolution of the identity (RI) approximation, starting from a given orbital basis set (OBS). The goal is to provide an accurate and universal solution for cases where no optimized ABSs are available. In this context, "universal" is understood as the ability of the ABS to be used for Coulomb, exchange, and correlation energy fitting. The generation scheme (denoted AutoAux) works by spanning the product space of the OBS using an even-tempered expansion for each atom in the system...

REVIEW
Rosanne M Kho, Mary Ellen Wechter
Opportunistic salpingectomy (OBS) is gaining momentum as a potential strategy for preventing epithelial ovarian cancer (EOC). OBS has been associated with a 40-65% decrease in the incidence of EOC when performed at the time of benign hysterectomy in patients at population-level risk for EOC. Current data suggests minimal disadvantage or "cost" to the patient and system from this practice in terms of estimated blood loss (EBL), operative time, length of hospital stay, ovarian reserve depletion, and complications attributable to OBS...

OBJECTIVE Patient-reported outcomes are increasingly used in studies of vestibular schwannoma (VS); however, few studies have examined self-evaluated facial nerve function and its relation to physician-reported outcomes. The primary objective of this study was to compare patient self-evaluations of facial disability with physician-evaluated facial nerve status and with self-evaluations of a healthy control group. The second objective was to provide insight into the controversial subject of the optimal initial management of small- and medium-sized VSs; consequently, the authors compared patient-reported facial nerve disability following treatment via observation (OBS), Gamma Knife surgery (GKS), or microsurgery (MS)...

REVIEW
Simone D'Angeli, Maria Maddalena Altamura
The olive tree is a plant of economic value for the oil of its drupe. It is a cultigen complex composed of genotypes with differences in cold-hardiness. About 90% of the oil is stored in oil bodies (OBs) in the drupe during the oleogenic phase. Phenols and lipids contribute to oil quality, but the unsaturated fatty acid (FA) fraction is emerging as the most important for quality, because of the very high content in oleic acid, the presence of ω6-linoleic acid and ω3-linolenic acid, and the very low saturated FA content...

Understanding antibiotic adsorption on natural colloids is crucial for prediction of the behavior, bioavailability and toxicity of antibiotics in natural waters. In the present study, the filtered water (dissolved phase, <0.7μm) was further separated into colloidal phase (1kDa-0.7μm) and soluble phase (<1kDa) by cross-flow ultrafiltration (CFUF), and the spatial-temporal variation and distribution of six antibiotics in multi-phases were investigated in Baiyangdian Lake. Results indicated that antibiotic concentrations differed significantly with sampling location and time...

Sediment resuspension plays an important role to provide nutrient release for algal growth in large shallow lakes. The settling velocity (w s ) is the key parameter for understanding the suspended sediment transport. In this paper, acoustic Doppler velocimeter (ADV) and optical backscatter sensor (OBS) instruments were used to measure in situ velocities and suspended sediment concentration (SSC) simultaneously without affecting the ambient turbulence in the bottom layer of Lake Taihu. The results showed that (1) ADV echo intensity (EI) could be transferred into SSC successfully by using a simple logarithmic relationship with a strong correlation of 0...
