Acetonitrile suspensions of the dichlorido complexes [MCl2(κ4C,N,N',P-L)] (M = Rh (1), Ir (2)) react with AgSbF6 in a 1/2 molar ratio affording the bis-acetonitrile complexes [M(κ4C,N,N',P-L)(NCMe)2][SbF6]2 (3, 4). The reaction takes place in a sequential manner and the intermediates can be isolated varying the M/Ag molar ratio. In a 2/1 molar ratio, it affords the dimetallic monochlorido-bridged compounds [{MCl(κ4C,N,N',P-L)}2(μ-Cl)][SbF6] (5, 6). In a 1/1 molar ratio, the monosubstituted solvato-complexes [MCl(κ4C,N,N',P-L)(Solv)][SbF6] (Solv = H2O, MeCN, 7-10) were obtained...

This study investigated the clinical utility of the Achenbach System of Empirically Based Assessment (ASEBA) for identifying youth at risk for suicide. Specifically, we investigated how well the Total Problems scores and the sum of two suicide-related items (#18 "Deliberately harms self or attempts suicide" and #91 "Talks about killing self") were able to distinguish youth with a history of suicidal behavior. Youth (N = 1117) aged 5-18 were recruited for two studies of mental illness. History of suicidal behavior was assessed by semi-structured interviews (K-SADS) with youth and caregivers...

RATIONALE: Brexpiprazole, a serotonin-dopamine activity modulator, is approved in the USA as an adjunctive therapy to antidepressants for treating major depressive disorders. Similar to the N-methyl-D-aspartate receptor (NMDAR) antagonist ketamine, the combination of brexpiprazole and fluoxetine has demonstrated antidepressant-like effects in animal models of depression. OBJECTIVES: The present study was conducted to examine whether the combination of brexpiprazole and fluoxetine could affect the tissue levels of amino acids [glutamate, glutamine, γ-aminobutyric acid (GABA), D-serine, L-serine, and glycine] that are associated with NMDAR neurotransmission...

BACKGROUND: There is an increased push for plastic surgery units in the United States to become independent departments administered autonomously rather than as divisions of a multispecialty surgery department. The purpose of this research was to determine if there are any quantifiable differences in the academic performance of departments versus divisions. METHODS: Using a list of the plastic surgery units affiliated with The American Council of Academic Plastic Surgeons (ACAPS), unit websites were queried for departmental status and to obtain a list of affiliated faculty...

Excretion of the tubular protein liver fatty acid binding protein (L-FABP) is a potential novel biomarker of renal dysfunction. We examined whether urine L-FABP excretion adds prognostic information to the well-established risk markers, blood pressure (BP), albumin excretion and baseline GFR, regarding progression of chronic kidney disease (CKD). In a prospective study design a cohort of 74 stage 3-4 CKD patients (age 61 ± 13 years) were included. Glomerular filtration ratio (GFR, (51)Cr-EDTA-clearance), 24-hour ambulatory BP, 24-hour urinary albumin/creatinine ratio (UAC) and urinary L-FABP/creatinine ratio (U-L-FABP/C) were determined at baseline and after 18 months of follow-up...

The objective of this study was to investigate the effect of DO on nitrification in a sequencing batch reactor (SBR) treating low ammonia wastewater (40 mg N/L) at low temperature (14oC). During the 130 days of operation, three DO levels (5-6 mg DO/L, 2-3 mg DO/L and 0.8-1.0 mg DO/L) were tested. DO reduction resulted in lower ammonia oxidizing bacteria (AOB) and nitrite oxidizing bacteria (NOB) activity with decreasing ammonia conversion ratio (ACR) and increasing nitrite accumulation ratio (NAR). The maximum growth rates of AOB and NOB determined in this study (0...

OBJECTIVE: To compare rates of drug survival and clinical response during 2 years of follow-up in ankylosing spondylitis (AS) patients treated with etanercept or adalimumab in routine care. METHOD: Biological-naïve consecutive AS patients treated with etanercept (n = 163) or adalimumab (n = 82) were followed. Treatment discontinuation was due to inefficacy, adverse events, loss to follow-up, planning a pregnancy, or uveitis. Disease activity was assessed by the Ankylosing Spondylitis Disease Activity Score using C-reactive protein (ASDAS-CRP)...

An approach involving ion-pair switchable-hydrophilicity solvent based homogeneous liquid-liquid microextraction coupled to high-performance liquid chromatography has been applied for the preconcentration and separation of paraquat in the real sample. A mixture of triethylamine and water was used as the switchable-hydrophilicity solvent. The pH was regulated using carbon dioxide; hence the ratio of the ionized and non-ionized form of triethylamine could control the optimum conditions. Sodium dodecyl sulfate was utilized as an ion-pairing agent...

The aim of the present study was to evaluate the antiproliferative effect of phenylpropanoids isolated from the n-BuOH-soluble fraction of an ethanolic extract of Lagotis brevituba Maxim. The phenylpropanoids were identified as echinacoside, lagotioside, glucopyranosyl(1-6)martynoside, plantamoside, and verbascoside. Three of the compounds, lagotioside, glucopyranosyl(1-6)martynoside, and plantamoside, were isolated from L. brevituba for the first time. The antiproliferative activity of the isolates was evaluated in human gastric carcinoma (MGC-803), human colorectal carcinoma (HCT116), human hepatocellar carcinoma (HepG2), and human lung cancer (HCT116) cells using an 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay...

Spawning performance of pinfish Lagodon rhomboides without use of hormonal aids was monitored over an extended season. Nearly three million eggs were obtained from 75 spawns collected over a 90-day consecutive period from a single population of four brood fish (1M:1F). A mean ± s.d. batch fecundity of 30·27 ± 22·64 eggs g(-1) female was estimated with 98·0 ± 0·06% of the batch composed of floating eggs which were 1·04 ± 0·04 mm in diameter and 85·71 ± 27·59% fertile. Floating eggs successfully hatched 54·65 ± 29·13% of the time which yielded larvae that were 2·59 ± 0·24 mm in length...

BACKGROUND: Fetal antiretroviral exposure is usually derived from the cord-to-maternal concentration ratio. This static parameter does not provide information on the pharmacokinetics in utero, limiting the assessment of a fetal exposure-effect relationship. OBJECTIVE: The aim of this study was to incorporate placental transfer into a pregnancy physiologically based pharmacokinetic model to simulate and evaluate fetal darunavir exposure at term. METHODS: An existing and validated pregnancy physiologically based pharmacokinetic model of maternal darunavir/ritonavir exposure was extended with a feto-placental unit...

Bait-trapping is a useful approach for monitoring fly population dynamics, and it is an effective tool for physical control of pest species. The aim of this study was to test a newly developed semi-automatic funnel fly trap with some modifications of the former prototype fly trap to study medically important fly population density. The efficacy of the semi-automatic funnel trap was assessed by field sampling during July 2013-June 2014 using 1-day tainted beef offal as bait. The modified semi-automatic funnel traps were able to capture a total of 151,141 adult flies, belonging to the families: Calliphoridae (n=147,248; 97...

RATIONALE: Obstructive sleep apnea (OSA) is associated with impaired renal function, but uncertainty exists over whether OSA treatment can influence renal outcomes. OBJECTIVES: To determine the effects of continuous positive airway pressure (CPAP) on renal function in subjects with co-existing OSA and cardiovascular disease. METHODS: This was a substudy of the international Sleep Apnea and cardioVascular Endpoints (SAVE) trial that randomized 2717 patients with moderate-severe OSA and established coronary or cerebrovascular disease to receive CPAP plus usual care, or usual care alone...

BACKGROUND: Leukocyte telomere length (LTL) is a potential biomarker of cancer prognosis; however, evidence for renal cell carcinoma (RCC) is inconsistent. METHODS: We investigated LTL and RCC-specific survival among 684 cases from the US kidney cancer study (USKC) and 241 cases from the prostate, lung, colorectal, and ovarian cancer screening trial (PLCO). Leukocyte telomere length was measured by quantitative polymerase chain reaction, and hazard ratios (HRs) and 95% confidence intervals (CIs) computed using multivariable Cox models...
