PURPOSE The purpose of this study was to investigate whether it is possible to estimate systemic inflammation and intestinal ischemia in incarcerated hernias using the lymphocyte-C-reactive protein ratio (LCR). METHODS A total of 116 patients who underwent an emergency operation due to incarcerated abdominal wall hernia were investigated retrospectively. The patients with incarcerated hernias were divided into two groups those who did not undergo intestinal resection and those who underwent intestinal resection due to strangulation. The two groups were analyzed based on sex, surgical operation (open, laparoscopic), length of stay, complications and mortality rates as well as preoperative period laboratory analyses, such as white blood cell, neutrophil, thrombocyte, and lymphocyte counts and C-reactive protein (CRP), neutrophil-lymphocyte ratio (NLR) and LCR values. RESULTS Twenty-five patients (21.6%) underwent intestinal resection due to strangulated hernia. Neutrophil count, lymphocyte count, CRP, platelet count, NLR, and LCR were significantly different in the strangulated hernia group. Receiver operating characteristic (ROC) analysis results showed that an LCR level below 0.02 had 80% sensitivity (58-92%) and 80.2% specificity (70-87%) for the diagnosis of strangulation. CONCLUSION A low preoperative LCR level in incarcerated hernias could be used as a bioindicator that helps to estimate the intestinal ischemia.Li-Fraumeni Syndrome (LFS) is characterized by risk of multiple primary malignancies in diverse sites, pediatric onset, near complete penetrance by age 70 years, limited options for prevention, and substantial uncertainty regarding disease manifestation and prognosis. Forty-five families, including 117 individuals aged 13-81 years, enrolled in the US National Cancer Institute's Li-Fraumeni Syndrome Study completed 66 interviews regarding their LFS experiences. An interdisciplinary team used modified grounded theory to examine family distress regarding expectations of loss and change due to likely cancer diagnoses, and the consequences of this likelihood across physical, social, and emotional domains. Disease-free periods were characterized by fearful anticipation of diagnosis or recurrence, uncertainty regarding post-treatment quality of life, and planning for shifts in family dynamics to enable caregiving. The chronicity of waiting for these changes incited dread and inhibited effective coping with the pragmatic, emotional, and existential challenges of the syndrome. Consequently, families reported high burden on roles and resources and limited guidance to prepare for, or achieve resolution with, grief. Anticipatory loss, the experience of bereavement prior to an expected change, distinguishes hereditary cancer risk from a sporadic diagnosis. Such grief is often incomplete in impact or meaning, subjected to rapid or profound change as conditions worsen, and poorly understood. In this study, losses were compounded by profound uncertainty, a chronic feature of LFS, which compromised mourning. Long-term engagement of mental health providers with bereavement training, in partnership with genetics providers, can provide invaluable educational and psychological support to families as they navigate these implacable challenges.Understanding the mechanisms that control the body's response to inflammation is of key importance, due to its involvement in myriad medical conditions, including cancer, arthritis, Alzheimer's disease and asthma. While resolving inflammation has historically been considered a passive process, since the turn of the century the hunt for novel therapeutic interventions has begun to focus upon active manipulation of constituent mechanisms, particularly involving the roles of apoptosing neutrophils, phagocytosing macrophages and anti-inflammatory mediators. Moreover, there is growing interest in how inflammatory damage can spread spatially due to the motility of inflammatory mediators and immune cells. For example, impaired neutrophil chemotaxis is implicated in causing chronic inflammation under trauma and in ageing, while neutrophil migration is an attractive therapeutic target in ailments such as chronic obstructive pulmonary disease. We extend an existing homogeneous model that captures interactions between inflammatory mediators, neutrophils and macrophages to incorporate spatial behaviour. Through bifurcation analysis and numerical simulation, we show that spatially inhomogeneous outcomes can present close to the switch from bistability to guaranteed resolution in the corresponding homogeneous model. Finally, we show how aberrant spatial mechanisms can play a role in the failure of inflammation to resolve and discuss our results within the broader context of seeking novel inflammatory treatments.DrugMatrix is a valuable toxicogenomic dataset, which provides in vivo transcriptome data corresponding to hundreds of chemical drugs. However, the relationships between drugs and how those drugs affect the biological process are still unknown. The high dimensionality of the microarray data hinders its application. The aims of this study are to (1) represent the transcriptome data by lower-dimensional vectors, (2) compare drug similarity, (3) represent drug combinations by adding vectors and (4) infer drug mechanism of action (MoA) and genotoxicity features. We borrowed the latent semantic analysis (LSA) technique from natural language processing to represent treatments (drugs with multiple concentrations and time points) by dense vectors, each dimension of which is an orthogonal biological feature. The gProfiler enrichment tool was used for the 100-dimensional vector feature annotation. The similarity between treatments vectors was calculated by the cosine function. Adding vectors may represent drug combinations, treatment times or treatment doses that are not presented in the original data. Drug-drug interaction pairs had a higher similarity than random drug pairs in the hepatocyte data. The vector features helped to reveal the MoA. Differential feature expression was also implicated for genotoxic and non-genotoxic carcinogens. An easy-to-use Web tool was developed by Shiny Web application framework for the exploration of treatment similarities and drug combinations (https//bioinformatics.fafu.edu.cn/drugmatrix/). We represented treatments by vectors and provided a tool that is useful for hypothesis generation in toxicogenomic, such as drug similarity, drug repurposing, combination therapy and MoA.Ubiquitin ligase VpRH2 is a negative regulator in the grape ABA pathway by inhibiting ABL1, PYR1 and GRP2A expressions, and its promoter is inhibited by ABA treatment. In higher plants, ubiquitin ligases play key roles in various cellular processes. As in our previous study (Wang et al. in J Exp Bot 681669-1687, 2017), grape RING-H2-type ubiquitin ligase gene VpRH2 and its promoter was induced by powdery mildew and showed resistance to the disease. Diverse small-molecule hormones, like salicylic acid (SA), methyl jasmonate (MeJA) or abscisic acid (ABA), play pivotal roles in plant resistance. Here we found that VpRH2 expression could be induced by SA and MeJA treatment, but inhibited by ABA treatment. The promoter of VpRH2 revealed a similar variation trend under exogenous hormone treatments as the gene expression by GUS activity assay. By a series of deletion fragments, the promoter fragment of VpRH2-P656 to VpRH2-P513 was necessary in response to MeJA treatment, and the inhibition of ABA treatment to the VpRH2 promoter was independent of the ABRE motif. Over-expression of VpRH2 in Arabidopsis thaliana plants displayed ABA-insensitive phenotypes at the germination stage compared to wild type plants. In VpRH2 over-expressing Vitis vinifera cv. Thompson Seedless plants after ABA treatments, the expression of the ABA pathway related genes ABL1 and PYR1 showed a suppresive trend. Moreover, VpGRP2A (an VpRH2-interacting protein) also showed a suppresive trend in response to ABA treatment in VpRH2-overexpressing plants. Our results demonstrate that VpRH2 is a negative regulator in the grape ABA signal pathway by inhibiting ABL1, PYR1 and GRP2A expressions, and its promoter was also inhibited by ABA treatment.Conventional flow cytometers employ hydrodynamic focusing method to insure detection accuracy by forcing cells go through detected position. However, an increased flow velocity will significantly reduce detection precision due to a fact that cells will deviate center position and are easily silted in choke point. In an effort to overcome this limitation, a two-dimension ultrasonic particle focusing method are presented in this work to enhance the performance of flow cytometer. Two piezoelectric transducers are used to attach to a 250 μm × 250 μm rectangular fused silica flow channel to realize the modification. Finite element model simulation is performed for parametrical analysis and simplifying experiment design. 3 μm polystyrene fluorescent particles are adopted to test focusing effect. One dimension acoustic focusing is achieved at 2.95 MHz with single focusing node as well as 2, 3, 4 nodes focusing near 6, 9, 12 MHz respectively. The 2D focusing particle stream width in two dimensions is less than 10 μm. Results verified that this method is applicable for Jurkat cells. Sample flow maintains its stability without clogging up even at high sample concentration. Focusing still works at flow velocity over 100 μl/min. All these results certify this acoustic particles focusing method can enhance the performance of hydrodynamic flow cytometer by minor modification.Two analytical methods were developed using electrochemical and spectrometric techniques for the simultaneous determination of endocrine disruptors triclosan and methylparaben in the monitoring of personal care products. For the electroanalytical analyses, a sensitive electrode based on graphene quantum dots supported in chitosan was employed. Under optimized conditions and a working potential of typically + 0.60 V for triclosan and + 0.81 V (vs. Ag/AgCl) for methylparaben, the calibration plots obtained by differential pulse voltammetry were linear in the range 0.10 to 10.0 μmol L-1. The detection limits were 0.03 and 0.04 μmol L-1 for triclosan and methylparaben, respectively. For the spectrometric method, UV/VIS spectrometry was used with a mathematical processing of non-linear deconvolution. This processing was used to solve the problem of overlapping absorption bands of triclosan (282 nm) and methylparaben (257 nm), which enabled simultaneous determination. The calibration plots by UV/VIS spectrometry were linear in the range 1.0 to 14.0 μmol L-1 with detection limits of 0.42 and 0.37 μmol L-1, respectively, for triclosan and methylparaben. Similar results obtained from the calibration plots of individual analytes suggest that the methods can be applied for individual or simultaneous determination of these species. Both methods were employed in the analysis of five samples of personal care products toothpaste, antiseptic soap, antiseptic deodorant, shampoo, and a bath kit (soap and shampoo). The statistical tests indicated that there were no significant differences regarding the accuracy and precision of the data provided by the two methods described herein.
