Di-(2-ethylehxyl) phthalate (DEHP) is one of the most broadly representative phthalic acid esters (PAEs) used as a plasticizer in polyvinyl chloride (PVC) production, and is considered to be an endocrine-disrupting chemical. DEHP and its monoester metabolites are responsible for adverse effects on human health. An efficient DEHP-degrading bacterial strain Rhodococcus ruber YC-YT1, with super salt tolerance (0⁻12% NaCl), is the first DEHP-degrader isolated from marine plastic debris found in coastal saline seawater...

Given the sub-lethal risks of synthetic surfactants, rhamnolipid is a promising class of biosurfactants with the potential to promote the bioavailability of polycyclic aromatic hydrocarbons (PAHs), to provide a favorable substitute for synthetic surfactants. However, few previous studies have integrated the behavior and mechanism behind rhamnolipid-influenced PAH biosorption and biodegradation. This is, to our knowledge, the first report of a bacterial envelope regulated link between phenanthrene (PHE) biosorption and biodegradation by rhamnolipid-induced PHE-degrading strain Pseudomonas sp...

An important unmet need in the management of primary mediastinal B-cell lymphoma (PMBCL) is to identify the patients for whom first line therapy will fail, in order to intervene before the lymphoma becomes refractory. High heterogeneity of intratumoral 18F-fluorodeoxyglucose (18FDG) uptake distribution on positron emission tomography/computed tomography (PET/CT) scans has been suggested as a possible marker of chemo-resistance in solid tumors. In the present study, we investigated the prognostic value of metabolic heterogeneity (MH) in 103 PMBCL patients prospectively enrolled in the International Extranodal Lymphoma Study Group (IELSG) 26 study, aimed at clarifying the role of PET in this lymphoma subtype...

Boer × Spanish kid goats (n = 48) were used to evaluate effects of using ground woody products in feedlot diets on growth performance and blood serum chemistry. A completely randomized study design was used with two feeding periods (Period 1 = 70% concentrate, d 0 to 26; Period 2 = 86% concentrate, d 27 to 64). Goats were individually fed 1 of 6 diets that differed only by roughage source (n = 4 wether males and 4 females/treatment; initial BW = 22 ± 2 kg): cottonseed hulls (CSH; control) or ground wood consisting of redberry (RED), blueberry (BLUE), one-seed (ONE), or eastern red cedar (ERC) Juniperus spp...

BACKGROUND: APPLE Schools is a Comprehensive School Health (CSH) project, started in schools in socioeconomically disadvantaged areas where dietary habits are poor, physical activity (PA) levels are low, and obesity rates are high. Earlier research showed program effects whereby energy intake, PA and weight status of students in APPLE Schools had reached similar levels as that of students in other schools. However, it is unknown whether the effects of CSH are sustained when children grow into adolescents...

Several developmental windows, including placentation, must be negotiated to establish and maintain pregnancy. Impaired placental function can lead to pre-eclampsia and/or intrauterine growth restriction (IUGR), resulting in increased infant mortality and morbidity. It has been hypothesized that chorionic somatomammotropin (CSH), plays a significant role in fetal development, potentially by modifying maternal and fetal metabolism. Recently, using lentiviral-mediated in vivo RNA interference in sheep, we demonstrated significant reductions in near-term (135 days of gestation; dGA) fetal and placental size, and altered fetal liver gene expression, resulting from CSH deficiency...

Concrete is the most important construction material used by mankind and, at the same time, one of the most complex substances known in materials science. Since this mineral compound is highly porous, a better understanding of its surface chemistry, and in particular the reaction with water, is urgently required to understand and avoid corrosion of infrastructure like buildings and bridges. We have gained insight into proton transfer from concrete upon contact with water by applying the so-called Surface Science approach to a well-defined mineral, Wollastonite...

Considering the significance in survival and virulence, we have made an attempt to understand modulations in the membrane and cell wall properties of Candida albicans hyphae induced by temperature (37 °C) and neutral pH and yeast form cells grown under low hydrostatic pressure (LHP). Our results suggest that cell surface hydrophobicity (CSH) and adhesion are dynamic properties determined largely by the microenvironment rather than morphological forms, citing the significance of variation in niche specific virulence...

Calcium-silicate-hydrate (CSH)/polymer nanocomposites were synthesized with the layer-by-layer (LBL) method, and their morphology and mechanical properties were investigated using atomic force microscopy (AFM) imaging and AFM nanoindentation. Different sets of polymers were used to produce CSH/polymer nanocomposites. The effect of different factors including dipping time, calcium to silicate ratios (C/S ratios) and pH on morphology was investigated. CSH/polymer nanocomposites made with different sets of polymers showed variation in morphologies...

Levornidazole is a novel third-generation nitroimidazoles antibiotic which metabolism and disposition in human are not well known. We have previously developed two methods to quantify levornidazole and its phase I metabolites, Ml (Hydroxylation metabolite), M2 (N-dealkylation metabolite) and M4 (Oxidative dechlorination metabolite), in human plasma and urine. In this study, we developed three novel liquid chromatographic-tandem mass spectrometric (LC-MS/MS) methods and analyzed its phase II metabolites, sulfate conjugate (M6) and glucuronide conjugate (M16), in human plasma and urine, and the parent drug and above-mentioned five metabolites in human feces samples...

The Fahr syndrome (FS) is a rare degenerative neurological disorder (its prevalence is <0.5%). FS is distinguished by the presence of abnormal bilateral intracranial calcifications with a predilection for the basal ganglia, also presented by movement disorders such as parkinsonism, paresis, and speech disorders. Chronic subdural hematoma (CSH), which is typically the result of mild head trauma, is a regularly encountered condition in elderly. A 63-year-old man has referred to our clinic from another hospital with a history of mild head trauma approximately a month ago...

IMPORTANCE: Diabetic retinopathy (DR) is one of the most common of all diabetic complications. The number of people with DR in the United States is expected to increase to 16 million by 2050. DR is the leading cause of blindness among working-age adults in many different countries, including the United States. In later DR stages, neovascularization is associated with extensive retinal capillary non-perfusion and vitreo-proliferation leading to retinal detachment. This neovascularization is orchestrated by an imbalance of growth factors in the retina from which somatolactogens (pituitary growth hormone, GH-N; placental growth hormone, GH-V; prolactin, PRL; and placental lactogen, PL, also referred as chorionic somatomammotropin, CSH), may play an important role...

Sphingomonads are isolated at exceptionally high frequency from organic polluted environments and assumed to be more hydrophobic than other Gram-negative bacteria. However, the potential roles of cell-surface hydrophobicity (CSH) in the cell survival in polluted environment, as well as the mechanisms underlying the CSH of sphingomonads, remain unclear. Sphingobium hydrophobicum C1T is a highly hydrophobic sphingomonad isolated from electronic-waste contaminated sediment. In this study, we found that exposure to the typical pollutants in electronic-waste contaminated sediment, such as the heavy metal ion Pb and the organic compound deca-brominated diphenyl ether (deca-BDE), resulted in the development of even higher CSH of the hydrophobic strain C1T ; but no significant change was observed in the low CSH of its hydrophilic variant C2...
