Laboratory survival of Drosophila suzukii under simulated winter conditions of the Pacific Northwest and seasonal field trapping in five primary regions of small and stone fruit production in the United States.

BACKGROUND Drosophila suzukii was first found in Oregon in August 2009. The threat of this pest to regional small and stone fruit production industries led to investigations on its overwintering capabilities in fruit-growing regions in the Pacific Northwest. Knowledge of its cold tolerance will help in the development of computer models to forecast seasonal population growth and decline. RESULTS Of 1500 adults or pupae, 22 (1.4%) individuals survived the 84 day experimental chilling period. Most (86%) of the survivors were subjected to 10 °C temperature treatments. Survival decreased significantly at lower temperature treatments. Freezing temporarily increased the mortality rate but did not significantly affect overall mortality over the trial period. Flies that emerged from pupae are estimated to survive for up to 103-105 days at 10 °C and for shorter periods at lower temperatures. Field trapping in five fruit production areas has demonstrated overwintering survival in California and Oregon, but lower survival is predicted in Eastern Washington and Michigan. CONCLUSION The experiments reported here indicate that long-term survival of D. suzukii is unlikely at temperatures below 10 °C. Field data from five climatic regions indicated extended low initial D. suzukii field presence in 2010 in all regions except California, where field presence was recorded earlier.
Inhibition of cyclooxygenase-2 prevents intra-abdominal adhesions by decreasing activity of peritoneal fibroblasts

Background Postoperative intra-abdominal adhesions are common complications after abdominal surgery. The exact molecular mechanisms that are responsible for these complications remain unclear, and there are no effective methods for preventing adhesion formation or reformation. The aim of the study reported here was to investigate the preventive effects and underlying potential molecular mechanisms of selective cyclooxygenase-2 (COX-2) inhibitors in a rodent model of postoperative intra-abdominal adhesions. Materials and methods The expression of COX-2 in postoperative intra-abdominal adhe-sions and normal peritoneal tissue was examined by immunohistochemistry and Western blot analysis. Assays were performed to elucidate the effect of COX-2 inhibition on hypoxia-induced fibroblast activity in vitro and on intra-abdominal adhesion formation in vivo. Results Hypoxia-induced COX-2 expression in peritoneal fibroblasts was increased in postoperative intra-abdominal adhesions. Inhibition of COX-2 attenuated the activating effect of hypoxia on normal peritoneal fibroblasts in vitro. Data indicate that selective COX-2 inhibitor prevents in vivo intra-abdominal adhesion by inhibition of basic fibroblast growth factor and transforming growth factor-beta expression, but not through an antiangiogenic mechanism. Furthermore, using selective COX-2 inhibitors to prevent intra-abdominal adhesions did not adversely affect the weight, bowel motility, or healing of intestinal anastomoses in a rat model. Conclusion These results show that hypoxia-induced COX-2 expression in peritoneal fibroblasts is involved in the formation of intra-abdominal adhesions. Inhibition of COX-2 prevents postoperative intra-abdominal adhesions through suppression of inflammatory cytokines.
A qualitative cross-national study of cultural influences on mobile data service design

As the use of mobile data services has spread across the globe, the effect of cultural differences on user requirements has become important issue. To date, however, little research has been conducted on the role cultural factors play in the design of mobile data services. This paper proposes a set of critical design attributes for mobile data services that takes cross-cultural differences into account. To determine these attributes, we devised a qualitative method and conducted in-depth long interviews in Korea, Japan, and Finland. We found 52 attributes considered important by mobile data service users, and 11 critical attributes that showed a clear correlation with characteristics of the user's culture. The paper concludes with a discussion of limitations and of implications for developers of mobile data services.
Transcript levels of aquaporin 1 and carbonic anhydrase IV as predictive indicators for prognosis of renal cell carcinoma patients after nephrectomy

Since failure of differentiation has been suggested to be involved in the neoplastic process and progression of tumors, we evaluated whether the transcript levels of differentiation markers of proximal renal tubular cells, from which renal cell carcinoma (RCC) arises, could be used as prognostic markers. We used Northern blot analysis to study the expression of aquaporin 1 (aqp1) and carbonic anhydrase IV (ca4) genes in 66 paired samples of primary RCC and non‐tumorous kidney tissues. Poor differentiation of tumor cells and non‐clear cell‐subtype RCC were significantly associated with low levels of aqp1 transcripts. When patients were divided into 2 groups according to level of aqp1 transcript in RCC, a low level of aqp1 was significantly associated with unfavorable outcome. Among 18 patients with metastatic RCC and 40 patients with moderately differentiated RCC, those with RCC expressing low levels of aqp1 mRNA demonstrated poorer survival than those with RCC expressing relatively high levels of aqp1. Similarly, decreased expression of ca4 mRNA in RCC was associated with poor survival. On multivariate analysis, transcript levels of aqp1 and stage of the tumor were the independent factors predicting disease‐specific survival. Transcript levels of aqp1 may serve as a new molecular prognostic marker in patients with RCC following nephrectomy. Int. J. Cancer (Pred. Oncol.) 79:1–7, 1998. © 1998 Wiley‐Liss, Inc.
Relative Roles of Deterministic and Stochastic Processes in Driving the Vertical Distribution of Bacterial Communities in a Permafrost Core from the Qinghai-Tibet Plateau, China

Understanding the processes that influence the structure of biotic communities is one of the major ecological topics, and both stochastic and deterministic processes are expected to be at work simultaneously in most communities. Here, we investigated the vertical distribution patterns of bacterial communities in a 10-m-long soil core taken within permafrost of the Qinghai-Tibet Plateau. To get a better understanding of the forces that govern these patterns, we examined the diversity and structure of bacterial communities, and the change in community composition along the vertical distance (spatial turnover) from both taxonomic and phylogenetic perspectives. Measures of taxonomic and phylogenetic beta diversity revealed that bacterial community composition changed continuously along the soil core, and showed a vertical distance-decay relationship. Multiple stepwise regression analysis suggested that bacterial alpha diversity and phylogenetic structure were strongly correlated with soil conductivity and pH but weakly correlated with depth. There was evidence that deterministic and stochastic processes collectively drived bacterial vertically-structured pattern. Bacterial communities in five soil horizons (two originated from the active layer and three from permafrost) of the permafrost core were phylogenetically random, indicator of stochastic processes. However, we found a stronger effect of deterministic processes related to soil pH, conductivity, and organic carbon content that were structuring the bacterial communities. We therefore conclude that the vertical distribution of bacterial communities was governed primarily by deterministic ecological selection, although stochastic processes were also at work. Furthermore, the strong impact of environmental conditions (for example, soil physicochemical parameters and seasonal freeze-thaw cycles) on these communities underlines the sensitivity of permafrost microorganisms to climate change and potentially subsequent permafrost thaw.
Narrow Fingerprint Template Synthesis by Clustering Minutiae Descriptors

SUMMARY Narrow swipe sensor has been widely used in embedded systems such as smart-phone. However, the size of captured image is much smaller than that obtained by the traditional area sensor. Therefore, the limited template coverage is the performance bottleneck of such kind of systems. Aiming to increase the geometry coverage of templates, a novel ﬁn-gerprint template feature synthesis scheme is proposed in the present study. This method could synthesis multiple input ﬁngerprints into a wider template by clustering the minutiae descriptors. The proposed method consists of two modules. Firstly, a user behavior-based Registration Pattern Inspection (RPI) algorithm is proposed to select the qualiﬁed candidates. Sec-ondly, an iterative clustering algorithm Modiﬁed Fuzzy C-Means (MFCM) is proposed to process the large amount of minutiae descriptors and then generate the ﬁnal template. Experiments conducted over swipe ﬁngerprint database validate that this innovative method gives rise to signiﬁcant improvements in reducing FRR (False Reject Rate) and EER (Equal Error Rate).
Transitions Between Care Settings at the End of Life Among Older Homecare Recipients

Objectives: Objectives were to (a) describe transitions between care settings in older homecare recipients at the end of life, and (b) examine what personal (e.g., age, sex) and health system factors (e.g., hospital bed supply) predict care transitions. Methods: The study involved analysis of administrative health care data and was based on a complete cohort of homecare recipients aged 65 years or older who died in Manitoba, Canada between 2003 and 2006 (N = 7,866). Results: More than half of homecare recipients had at least one care transition in the last 30 days before death and 21% had two or more hospitalizations in the last 90 days. Both personal characteristics and health system factors were related to transitions and hospitalizations. Discussion: The findings suggest that homecare recipients are an important population to focus on in terms of reducing potentially burdensome transitions and enhancing the end-of-life experience for them and their family.
Fatty acid binding protein 7 and n‐3 poly unsaturated fatty acid supply in early rat brain development

Fatty acid binding protein 7 (FABP7), abundant in the embryonic brain, binds with the highest affinity to docosahexaenoic acid (DHA) and is expressed in the early stages of embryogenesis. Here, we have examined the consequences of the exposure to different DHA levels and of the in utero depletion of FABP7 on early rat brain development. Neurodevelopment was evaluated through the contents of two proteins, connexin 43 (Cx43) and cyclin‐dependent kinase 5 (CDK5), both involved in neuroblast proliferation, differentiation, and migration. The dams were fed with diets presenting different DHA contents, from deficiency to supplementation. DHA brain embryos contents already differed at embryonic day 11.5 and the differences kept increasing with time. Cx43 and CDK5 contents were positively associated with the brain DHA levels. When FABP7 was depleted in vivo by injections of siRNA in the telencephalon, the enhancement of the contents of both proteins was lost in supplemented animals, but FABP7 depletion did not modify phospholipid compositions regardless of the diets. Thus, FABP7 is a necessary mediator of the effect of DHA on these proteins synthesis, but its role in DHA uptake is not critical, although FABP7 is localized in phospholipid‐rich areas. Our study shows that high contents of DHA associated with FABP7 are necessary to promote early brain development, which prompted us to recommend DHA supplementation early in pregnancy. © 2015 Wiley Periodicals, Inc.

Regulation of granule size in human and horse eosinophils by number of fusion events among unit granules.

1. We have investigated the granule size distributions in human and horse eosinophils by time‐resolved patch‐clamp capacitance measurements. 2. During exocytosis of single granules the electrical capacitance of the plasma membrane increases in discrete steps. The steps in horse cells are about six times larger than those in human cells in accordance with the difference in granule size. 3. In both species a multimodal capacitance step size distribution is observed with a first peak at 6‐7 fF corresponding to granules with a diameter of about 450‐500 nm and a surface area of about 0.7 microns2, which we call the unit granule. The other peaks in the distributions correspond to multiples of the surface area of these units. 4. These results show that the larger granules are formed by fusion of several unit granules and the final size of mature granules is determined by the number of units allowed to fuse with each other. Whereas in human eosinophils most granules consist of one or two units, most granules of horse eosinophils are formed by fusion of seven to fifteen units. 5. The intracellular fusion events associated with vesicular traffic are believed to occur constitutively. In contrast, our results indicate that a cellular mechanism exists which regulates the size of the mature granules by determining the number of units allowed to fuse with each other. In view of our recent report that granule‐granule fusion can be activated by GTP gamma S, this regulation may possibly involve GTP‐binding proteins.
A Stochastic and Dynamic Vehicle Routing Problem in the Euclidean Plane

We propose and analyze a generic mathematical model for dynamic, stochastic vehicle routing problems, the dynamic traveling repairman problem (DTRP). The model is motivated by applications in which the objective is to minimize the wait for service in a stochastic and dynamically changing environment. This is a departure from classical vehicle routing problems where one seeks to minimize total travel time in a static, deterministic environment. Potential areas of application include repair, inventory, emergency service and scheduling problems. The DTRP is defined as follows: Demands for service arrive in time according to a Poisson process, are independent and uniformly distributed in a Euclidean service region, and require an independent and identically distributed amount of on-site service by a vehicle. The problem is to find a policy for routing the service vehicle that minimizes the average time demands spent in the system. We propose and analyze several policies for the DTRP. We find a provably optima.
A high quality, low cost router for MOS/LSI

This paper presents the implementation of an automatic router for the custom design of MOS integrated circuits. Standard cells are utilized for the logical functions and are interconnected by the router according to the specific design being produced. The design program operates at a very low cost and yields results comparable to manual routing. An expansion technique is used which will give 100 percent completion of interconnection. The router will handle any cell size and will route according to any predetermined design rules. An accuracy of one-hundredth of a mil can be maintained on chips over 300 mils on a side. The router may be used to build designs automatically or, because of its very low cost, can allow manual intervention to achieve more efficient layouts.
Functional and health promoting inherent attributes of Enterococcus hirae F2 as a novel probiotic isolated from the digestive tract of the freshwater fish Catla catla

Background Probiotic microorganisms are gaining global importance because of their use in the preparation of a nutraceutical or in the treatment of infections. As per the health industry demand, there is an urgent need for exploring new indigenous probiotic strains with its specific origin due to variation in gut microflora, different food habits and specific host-microbial interactions. The main objective of the present study was to isolate and identify a novel probiotic Enterococcus strain from the gut of Catla catla fish and evaluate its potentiality as a potent probiotic. Methods The whole study was designed with the isolation of novel lactic acid bacterial strain from the gut of Catla catla fish with their biochemical and molecular identifications. The potentiality of the isolated strain as a potent probiotic was carried out according to the parameters described in FAD/WHO guidelines for the evaluation of probiotics in food. Results The isolated strain was confirmed as Enterococcus hirae F2 on the basis of various biochemical and 16s rRNA gene sequencing methods. Enterococcus hirae F2 was able to survive under highly acidic and bile salt concentration with the ability for the production of lipase and Bsh enzyme. It was also able to survive under simulated gastrointestinal conditions with the inhibition ability of various pathogens. The antioxidant potentiality with the cell surface hydrophobicity and cell aggregation ability confirms its potentiality as a potent probiotic. All the results detail the potency of Enterococcus hirae F2 as a novel probiotic for a safer use. Discussion The isolation of Enterococcus hirae with probiotic potential from the gut of fish is a new approach and done for the first time. However, the whole study concluded that the isolated strain might be used as a novel probiotic in the food industry for the production of new probiotic products which imparts health benefits to the host.
The K+ Channel KCa3.1 as a Novel Target for Idiopathic Pulmonary Fibrosis

Background Idiopathic pulmonary fibrosis (IPF) is a common, progressive and invariably lethal interstitial lung disease with no effective therapy. We hypothesised that KCa3.1 K+ channel-dependent cell processes contribute to IPF pathophysiology. Methods KCa3.1 expression in primary human lung myofibroblasts was examined using RT-PCR, western blot, immunofluorescence and patch-clamp electrophysiology. The role of KCa3.1 channels in myofibroblast proliferation, wound healing, collagen secretion and contraction was examined using two specific and distinct KCa3.1 blockers (TRAM-34 and ICA-17043 [Senicapoc]). Results Both healthy non fibrotic control and IPF-derived human lung myofibroblasts expressed KCa3.1 channel mRNA and protein. KCa3.1 ion currents were elicited more frequently and were larger in IPF-derived myofibroblasts compared to controls. KCa3.1 currents were increased in myofibroblasts by TGFβ1 and basic FGF. KCa3.1 was expressed strongly in IPF tissue. KCa3.1 pharmacological blockade attenuated human myofibroblast proliferation, wound healing, collagen secretion and contractility in vitro, and this was associated with inhibition of TGFβ1-dependent increases in intracellular free Ca2+. Conclusions KCa3.1 activity promotes pro-fibrotic human lung myofibroblast function. Blocking KCa3.1 may offer a novel approach to treating IPF with the potential for rapid translation to the clinic.
Sympathetic Innervation of Cerebral Arteries: Prejunctional Supersensitivity to Norepinephrine After Sympathectomy or Cocaine Treatment

The inactivation of the norepinephrine transmitter in the region of the adrenergic receptor is one important function of the sympathetic nerve terminals innervating blood vessels. This capacity was tested on isolated cat's middle cerebral artery (MCA) by recordings of the contractile response induced by norepinephrine at various stages after sympathectomy (excision of the superior cervical ganglion). Within three days after denervation, when fluorescence microscopy revealed a disappearance of neuronal norepinephrine in the vessel wall, there was a threefold increase in sensitivity of the test system which was not further enhanced at two weeks. This, and the finding of a similar amount of sensitization (of non-denervated vessels) to norepinephrine or tyramine after cocaine treatment, showed that a prejunctional type of sensitivity had developed. The sympathetic denervation did not influence the dose-response curve obtained with acetylcholine, supporting the specific nature of the supersensitivity reaction only to the sympathetic transmitter. Half a year after sympathectomy the sensitivity of the pial arteries to norepinephrine returned to control levels despite the absence of reinnervation, indicating that postjunctional changes also occurred. The findings offer further evidence for a functional role of the sympathetic nerves supplying intracranial arteries and show that the mode of innervation resembles that found in peripheral vessels.
Inhibition of protein phosphatase 2A with a small molecule LB100 radiosensitizes nasopharyngeal carcinoma xenografts by inducing mitotic catastrophe and blocking DNA damage repair

Nasopharyngeal carcinoma (NPC), while uncommon worldwide, is a major health problem in China. Although local radiation and surgery provide good control of NPC, better treatments that permit reductions in radiation dosing are needed. Inhibition of protein phosphatase 2A (PP2A), a ubiquitous multifunctional enzyme with critical roles in cell cycle regulation and DNA-damage response, reportedly sensitizes cancer cells to radiation and chemotherapy. We studied PP2A inhibition with LB100, a small molecule currently in a Phase I clinical trial, on radiosensitization of two human nasopharyngeal cell lines: CNE1, which is reportedly radioresistant, and CNE2. In both cell lines, LB100 exposure increased intracellular p-Plk1, TCTP, and Cdk1 and decreased p53, changes associated with cell cycle arrest, mitotic catastrophe and radio-inhibition of cell proliferation. Mice bearing subcutaneous xenografts of either cell line were administered 1.5 mg/kg LB100 daily for three days and a single dose of 20 Gy radiation (day 3), which produced marked and prolonged tumor mass regression (dose enhancement factors of 2.98 and 2.27 for CNE1 and CNE2 xenografts, respectively). Treatment with either LB100 or radiation alone only transiently inhibited xenograft growth. Our results support further exploration of PP2A inhibition as part of radiotherapy regimens for NPC and potentially other solid tumors.
Clinical Outcomes after Intravascular Ultrasound Assessment of Coronary Intermediate Lesions

Purpose: Coronary angiography has limitations in the assessment of intermediate coronary lesions (ICL). Intravascular ultrasound (IVUS) can evaluate more accurately the severity of a lesion to guide the therapeutic strategy. This study sought to evaluate long-term clinical outcomes after IVUS-guided coronary revascularization of ICL lesions in patients from the Western Mediterranean region of coastal North Africa (Maghreb) in whom IVUS severity criteria have not been validated. Methods: We conducted a prospective monocentric study including 113 patients with angiographic ICL evaluated by IVUS. Minimal lumen area (MLA) cut-offs value to perform revascularization were 6 mm2 for the left main coronary artery (LMCA) and 4 mm2 for nonLMCA lesions. The primary outcome was defined as a composite of major adverse cardiac events (MACE) including death, myocardial infarction (MI), and target lesion revascularization (TLR) at 12 months. Results: Mean age was 59,5 ± 12,0 years, 79% were men. Multi-vessel disease was present in 65.5% of our patients, of whom 36 patients had LMCA disease. We analysed 146 arteries with 178 lesions. Revascularization was deferred for n=46 (40.7%) patients after IVUS evaluation. After a mean follow-up of 20± 10 months, we observed no significant differences between the revascularized patients and the patients with a deferred revascularization strategy in terms of mortality (1.5% and 2.2% respectively, p=0.7), and a favourable safety trend for 12-month rate of MACE (10.6% and 2.2% respectively, p=0.165), MI (4.5% and 2.2%, p=0.44) and TLR (10.7% and 2.2%, p=0.23). Conclusion: We demonstrate that previously validated IVUS criteria to defer revascularization of angiographically ICL can be safely applied to Maghrebi patients.
