Abstract
Objective To study the extent of diagnostic discrepancies at admission (diagnoses made by doctors in the Emergency Department) and discharge (final diagnoses at the ward) in our Emergency Department (ED) where the doctors have direct admitting rights; and how such discrepant diagnoses affected inter-departmental transfer of patients after their admission. Method A non-concurrent cohort study was performed on admissions through our ED between 24th to 30th April 1997. The admitting and discharge diagnoses and units were recorded. The reasons for the unmatched diagnoses and inter-departmental transfers were studied. The significance of transfers amongst patients who had matched and unmatched diagnoses was compared using the Chi-test at 95% confidence interval. Results Three hundred and sixty-one admissions were recorded during the study period. There were 314 (86.7%) and 47 (13.3%) admissions with matched and unmatched diagnoses respectively. Nine of the 47 admissions with unmatched diagnoses and 16 of the 314 admissions with matched diagnoses were transferred (p=0.001). Conclusion The ED doctors achieved a high level of diagnostic accuracy. The most common reason for unmatched diagnosis was because of the difficulty of diagnosing the patient's complex medical problem in the short contact time in the ED. The level of accuracy should increase with the advent of more diagnostic modalities and increased contact time with the patients in the ED.

Abstract
Depression is associated with poor antiretroviral therapy (ART) adherence among people living with HIV/AIDS. This relationship may be moderated by an individual's social network characteristics. Our study sought to examine social network correlates of treatment adherence among HIV-positive men recruited from social service agencies throughout Los Angeles County (N = 150) to inform technology-driven social support interventions for this population. We administered egocentric social network and computer-assisted survey interviews focused on demographic characteristics, health history, depressive symptoms, and ART adherence, where adherence was assessed by the number of reasons participants missed taking their medication, if ever. Significant univariate correlates of adherence were included in a multivariable regression analysis, where the moderating effect of having a network member who reminds participants to take their HIV medication on the relationship between depression and adherence was tested. Over 60% of participants reported clinically significant depressive symptoms; this was significantly associated with lower adherence among those without someone in their social network to remind them about taking their HIV medication, even after adjusting for covariates in an ordinary least squares regression (adjusted mean difference b = -1.61, SE = 0.42, p = 0.0003). Having a network member who reminds participants to take their ART medication significantly ameliorated the negative association between depression and treatment adherence, especially for those reporting greater depressive symptoms (p = 0.0394). Additionally, participants demonstrated high rates of technology use to communicate with social network members. In order to achieve the aims of the National HIV/AIDS Strategy, innovative interventions addressing mental health to improve ART adherence are needed. Network strategies that leverage technology may be helpful for improving ART adherence among HIV-positive men with comorbid depressive symptoms.

Abstract
Acrylamide (ACR) is a chemical intermediate utilized in industry. ACR is also formed during heating of foods containing carbohydrates and amino acids. Therefore, humans are widely exposed to ACR, and ACR neurotoxicity in humans is a significant public health issue attracting wide attention. In this study, we investigated the potential neuroprotective effects of epigallocatechin-3-gallate (EGCG), the most abundant polyphenolic compound in green tea, in PC12 cells treated with ACR. ACR-treated PC12 cells pretreated with various concentrations of EGCG (2.5, 5 and 10 μM) for 24 h had increased viability and acetylcholinesterase activity and reduced apoptosis and necrosis compared to cells exposed to ACR alone. EGCG reduced the expression of bax mRNA, decreased cytochrome c release, reduced intracellular calcium levels, inactivated caspase 3 and increased mitochondrial membrane potential, suggesting that EGCG prevents ACR-induced apoptosis through a mitochondrial-mediated pathway. In addition, EGCG inhibited the formation of reactive oxygen species and lipid peroxidation while enhancing superoxide dismutase activity and glutathione levels, thereby reducing oxidative stress. Our results indicate that pretreatment of PC12 cells with EGCG attenuates ACR-induced apoptosis by reducing oxidative stress. Therefore, drinking green tea may reduce nerve injury induced by ACR.

Abstract
Speckled (Spc), an X-ray-induced lethal mutant of Bombyx mori, exhibits a mosaic dark-brown-spotted larval epidermis in both sexes and egg-laying problems only in females. Here, we report the morphological characterization and molecular mapping of the Spc mutant. Morphological investigations revealed that the epidermal ultrastructure of the small, dark-brown spots was more dense than that of the white regions in both Spc/+ mutants and wild type, and that the lethality of the Spc/Spc mutants occurred during early embryogenesis. Furthermore, the ovarioles and ovipositor were disconnected in approximately 85.5% of Spc/+ females, a further 2.5% had a connection between the ovarioles and ovipositor that was too narrow to lay eggs. The remaining females showed a normal connection similar to that of the wild type. We successfully narrowed down the location of the Spc mutation to a region on chromosome 4 that was ∼1041 kb long. Gene-prediction analysis identified 25 candidate genes in this region. Chromosome structure analysis indicated that a ∼305 kb deletion was included in the mapping region. Temporal and spatial reverse transcription PCR (RT-PCR) analysis showed that several genes in the mapped region are associated with the Spc mutant. Although the genes responsible for the Spc mutation were not definitively identified, our results further the current understanding of the complex mechanism underlying the multiple morphological defects in Spc mutants.

Abstract
We conducted a study to investigate the association between ERCC1 (rs3212986) and ERCC2 (rs13181) gene polymorphisms and the risk of pancreatic cancer in a Chinese population. A total of 217 pancreatic cancer patients and 244 control subjects were recruited from the Nuclear Industry 215 Hospital of Shaanxi Province between February 2013 and December 2014. Genomic DNA was extracted from peripheral blood samples using a TIANamp Blood DNA Kit (Tiangen, Beijing, China) according to the manufacturer's instructions. The ERCC1 rs3212986 and ERCC2 rs13181 polymorphisms were genotyped by polymerase chain reaction-restriction fragment length of polymorphism. Unconditional logistic regression analyses showed that subjects with the CC genotype of ERCC1 rs3212986 were susceptible to the development of pancreatic cancer when compared with subjects with the AA genotype (OR = 2.57, 95%CI = 1.34-5.02). The ERCC1 rs3212986 gene polymorphism was associated with increased risk of pancreatic cancer in the dominant (OR = 1.54, 95%CI = 1.05-2.28) and recessive (OR = 2.22, 95%CI = 1.20-4.19) models. However, no significant difference was found between the ERCC2 rs13181 polymorphism and the risk of pancreatic cancer in the codominant, dominant, and recessive models. We suggest that the ERCC1 rs3212986 polymorphism increases susceptibility to pancreatic cancer in the codominant, dominant, and recessive models, although further studies are needed to confirm our findings.

Abstract
In quantum physics, measurements give random results and yield a corresponding random backaction on the state of the system subject to measurement. If a quantum system is probed continuously over time, its state evolves along a stochastic quantum trajectory. To investigate the characteristic properties of such dynamics, we perform weak continuous measurements on a superconducting qubit that is driven to undergo Rabi oscillations. From the data we observe a number of striking temporal correlations within the time dependent signals and the quantum trajectories of the qubit, and we discuss their explanation in terms of quantum measurement and photodetection theory.
