BACKGROUND: Evaluation of the nuclear to cytoplasmic ratio is commonly used for assessment of the presence of malignancy and for grading and typing of malignant neoplasms. Despite its widespread usage, little information exists regarding the accuracy and reproducibility of non-automated assessment. METHODS: Forty-seven cells obtained from Papanicolaou stained urine cytologies were assessed by quantitative image analysis for nuclear area and cell area. The nuclear/cytoplasmic ratio was calculated...

The effects of a biodegradable chelating agent, Ethylenediamine-N,N'-disuccinic acid (EDDS), on the speciation and bioavailability of iron (Fe(2+)) in anaerobic digestion were examined. Fe(2+) supplementation at 10mg/L increased methane yield, but the presence of 8mg/L sulfide led to the precipitation of Fe(2+) as FeS which limited its bioavailability. The results confirmed that the EDDS could replace common chelating agents with low biodegradability (EDTA and NTA), and improve the bioavailability of Fe(2+) by forming an Fe-EDDS complex, thereby protecting Fe(2+) from sulfide precipitation...

INTRODUCTION: Women experiencing intimate partner violence (IPV) navigate complex, dangerous decisions. Tailored safety information and safety planning, typically provided by domestic violence service providers, can prevent repeat IPV exposure and associated adverse health outcomes; however, few abused women access these services. The Internet represents a potentially innovative way to connect abused women with tailored safety planning resources and information. The purpose of this study was to compare safety and mental health outcomes at baseline, 6 months, and 12 months among abused women randomized to: (1) a tailored, Internet-based safety decision aid; or (2) control website (typical safety information available online)...

BACKGROUND: Perioperative respiratory adverse events (PRAE) are the most common critical incidents in paediatric anaesthesia and occur more often in infants. Use of laryngeal mask airways (LMAs) is associated with reduced PRAE compared with endotracheal tubes in older children (>1 year). We aimed to evaluate the effect of these devices on the incidence of PRAE in infants. METHODS: We did a randomised controlled trial at the Princess Margaret Hospital for Children in Perth (WA, Australia) by recruiting infants (aged 0-12 months) undergoing general (with or without regional or local) anaesthesia with anticipated fentanyl dose 1 μg/kg or lower for minor elective surgery...

BACKGROUND: Liver enzymes are released from hepatocytes into circulation and their activity can be measured in the blood. We examined whether the plasma activity of the liver enzyme ornithine carbamoyltransferase, determined by a novel liquid chromatography-mass spectrometry (LC-MS/MS) assay, could be utilized for the detection of OTC deficiency (OTCD), an X-linked inborn error of the urea cycle. METHODS: The plasma ornithine carbamoyltransferase (OTC) activity was assayed in the reverse reaction using isotopically labeled citrulline-d4 as a substrate and by determination of the product, ornithine-d4, by LC-MS/MS analysis...

Many children in low- and middle-income countries may have inadequate intake of vitamin B12 and folate; data confirming these inadequacies are limited. We used biochemical, demographic, behavioral and anthropometric data to describe the folate and vitamin B12 concentrations among six- to 23-month-old Nepalese children. Vitamin B12 (serum B12 < 150 pmol/L) and folate deficiencies (red blood cell (RBC) folate < 226.5 nmol/L) were assessed. We used logistic regression to identify predictors of vitamin B12 deficiency...
