Negligible effect of selective preoperative biliary drainage on perioperative resuscitation, morbidity, and mortality in patients undergoing pancreaticoduodenectomy.

OBJECTIVE To examine the effect of selective preoperative biliary drainage (BD) on perioperative resuscitation, morbidity, and mortality in patients undergoing pancreaticoduodenectomy. Biliary drainage prior to pancreaticoduodenectomy remains controversial. Proponents argue that it facilitates referral to high-volume tertiary centers, while detractors maintain that it increases surgical morbidity and mortality. DESIGN Retrospective analysis of single-institution tumor registry database. SETTING University medical center. PATIENTS From October 1, 2003, to May 31, 2008, 90 patients underwent pancreaticoduodenectomy for periampullary mass lesions. MAIN OUTCOME MEASURES Clinicopathologic data were reviewed and analyzed among patients who did and did not receive BD for their association with perioperative outcomes. chi(2) Analysis, independent-samples t tests, and Mann-Whitney U tests were used as appropriate. RESULTS Fifty-six patients (62%) underwent BD, and 34 (38%) did not. Intraoperative bile cultures were positive for 1 or more species of microorganisms in 88% of stented patients (35 of 40). There were no significant differences in fluid requirements, transfusion requirements, or surgery duration between patients who did and did not undergo BD. Estimated blood loss was increased in patients who received BD (625 mL vs 525 mL in patients who did not undergo BD; P = .03), while reoperation was significantly more common in nonstented patients (4% vs 15% in patients who did not undergo BD; P = .02). Intensive care unit stay, overall length of stay, pancreatic leak/abscess/fistula, infectious complications, postoperative percutaneous drainage, hospital readmission, and 30- and 90-day mortality were not significantly different between the 2 groups. CONCLUSIONS Although preoperative biliary stents may complicate the intraoperative management and lessen the postoperative complications of patients undergoing pancreaticoduodenectomy, only estimated blood loss and reoperation were significantly different in this cohort. Further study may reveal patient subgroups who may specifically benefit or suffer from preoperative biliary stenting. Currently, selective preoperative BD appears appropriate in the multidisciplinary management of patients with periampullary lesions.
Poor phenotypic integration of blue mussel inducible defenses in environments with multiple predators

Aquatic prey encounter an array of threat cues from multiple predators and killed conspecifics, yet the vast majority of induced defenses are investigated using cues from single predator species. In most cases, it is unclear if odors from multiple predators will disrupt defenses observed in single-predator induction experiments. We experimentally compared the inducible defenses of the common marine mussel Mytilus edulis to waterborne odor from pairwise combinations of three predators representing two attack strategies. Predators included the sea star, Asterias vulgaris (Asterias rubens), and the crabs Carcinus maenas and Cancer irroratus. The mussels increased adductor muscle mass in response to cues from unfed Asterias (a predatory seastar that pulls mussel shells open) and increased shell thickness in response to unfed Carcinus, a predatory crab that crushes or peels shells. However, the mussels did not express either predator specific response when exposed to the combined cues of Asterias and Carcinus, and mussels did not increase shell thickness when exposed to cues from Cancer alone or any pairwise combination of the three predators. Shell closure or ‘clamming up’ did not occur in response to any predator combination. These results suggest that predator-specific responses to the Asterias and Carcinus are poorly integrated and cannot be expressed simultaneously. Simultaneous cues from multiple predators affect the integration of predator specific defenses and predator odors from functionally similar predators do not necessarily initiate similar defenses. Ultimately, the degree that prey can integrate potentially disparate defenses in a multiple predator environment may have ecological ramifications and represent a seldom explored facet of the evolution of inducible defenses.
Reduced cross-linking demarcation line depth at the peripheral cornea after corneal collagen cross-linking.

PURPOSE To compare the corneal collagen cross-linking (CXL) demarcation line depth between the central and peripheral cornea after cross-linking using anterior segment optical coherence tomography. METHODS Retrospective interventional case series of 38 eyes with keratoconus or postoperative LASIK ectasia treated with riboflavin ultraviolet A CXL (UV-X, IROC). CXL demarcation line depth, corneal thickness, and the ratio of the CXL demarcation line depth to the corneal thickness were measured using anterior segment optical coherence tomography at the central cornea and at 2 and 4 mm from the corneal center in four regions: temporal, nasal, superior, and inferior. The CXL demarcation line depths at the center and periphery were compared using the Friedman test. RESULTS The CXL demarcation line was deepest in the central cornea (302 μm; range: 180 to 397 μm) and was reduced progressively toward the peripheral cornea, at nasal 2 mm (289.5 μm; range: 125 to 370 μm), at nasal 4 mm (206.5 μm; range: 100 to 307 μm), at temporal 2 mm (278.5 μm; range: 128 to 375 μm), and at temporal 4 mm (194 μm; range: 80 to 325 μm) (P<.001). The penetration proportion was greatest at the central cornea (64.8%; range: 44% to 80%) and was decreased toward the periphery, at nasal 2 mm (53.8%; range: 30% to 74%), at nasal 4 mm (33.8%; range: 19% to 53%), at temporal 2 mm (54.1%; range: 29% to 77%), and at temporal 4 mm (34.1%; range: 15% to 54%) (P⩽.001). CONCLUSIONS Both the CXL demarcation line depth and its proportion over the corneal thickness were greater at the central cornea than the peripheral cornea.
Transcriptomics of Desiccation Tolerance in the Streptophyte Green Alga Klebsormidium Reveal a Land Plant-Like Defense Reaction

Background Water loss has significant effects on physiological performance and survival rates of algae. However, despite the prominent presence of aeroterrestrial algae in terrestrial habitats, hardly anything is known about the molecular events that allow aeroterrestrial algae to survive harsh environmental conditions. We analyzed the transcriptome and physiology of a strain of the alpine aeroterrestrial alga Klebsormidium crenulatum under control and strong desiccation-stress conditions. Principal Findings For comparison we first established a reference transcriptome. The high-coverage reference transcriptome includes about 24,183 sequences (1.5 million reads, 636 million bases). The reference transcriptome encodes for all major pathways (energy, carbohydrates, lipids, amino acids, sugars), nearly all deduced pathways are complete or missing only a few transcripts. Upon strong desiccation, more than 7000 transcripts showed changes in their expression levels. Most of the highest up-regulated transcripts do not show similarity to known viridiplant proteins, suggesting the existence of some genus- or species-specific responses to desiccation. In addition, we observed the up-regulation of many transcripts involved in desiccation tolerance in plants (e.g. proteins similar to those that are abundant in late embryogenesis (LEA), or proteins involved in early response to desiccation ERD), and enzymes involved in the biosynthesis of the raffinose family of oligosaccharides (RFO) known to act as osmolytes). Major physiological shifts are the up-regulation of transcripts for photosynthesis, energy production, and reactive oxygen species (ROS) metabolism, which is supported by elevated cellular glutathione content as revealed by immunoelectron microscopy as well as an increase in total antiradical power. However, the effective quantum yield of Photosystem II and CO2 fixation decreased sharply under the applied desiccation stress. In contrast, transcripts for cell integrative functions such as cell division, DNA replication, cofactor biosynthesis, and amino acid biosynthesis were down-regulated. Significance This is the first study investigating the desiccation transcriptome of a streptophyte green alga. Our results indicate that the cellular response is similar to embryophytes, suggesting that embryophytes inherited a basic cellular desiccation tolerance from their streptophyte predecessors.
Motor neurons with limb-innervating character in the cervical spinal cord are sculpted by apoptosis based on the Hox code in chick embryo

In the developing chick embryo, a certain population of motor neurons (MNs) in the non-limb-innervating cervical spinal cord undergoes apoptosis between embryonic days 4 and 5. However, the characteristics of these apoptotic MNs remain undefined. Here, by examining the spatiotemporal profiles of apoptosis and MN subtype marker expression in normal or apoptosis-inhibited chick embryos, we found that this apoptotic population is distinguishable by Foxp1 expression. When apoptosis was inhibited, the Foxp1+ MNs survived and showed characteristics of lateral motor column (LMC) neurons, which are of a limb-innervating subtype, suggesting that cervical Foxp1+ MNs are the rostral continuation of the LMC. Knockdown and misexpression of Foxp1 did not affect apoptosis progression, but revealed the role of Foxp1 in conferring LMC identity on the cervical MNs. Furthermore, ectopic expression of Hox genes that are normally expressed in the brachial region prevented apoptosis, and directed Foxp1+ MNs to LMC neurons at the cervical level. These results indicate that apoptosis in the cervical spinal cord plays a role in sculpting Foxp1+ MNs committed to LMC neurons, depending on the Hox expression pattern. Summary: Hox-dependent apoptosis in the limbless neck region of the chick embryo eliminates a transient population of spinal motor neurons that express Foxp1 and have characteristics of limb-innervating LMC neurons.
EFFECT OF SURFACE MECHANICAL ATTRITION TREATMENT ON ROUGHNESS AND WETTABILITY OF AISI 316L

Surface roughness and wettability determines the rate and quality of protein adsorption and cells adhesion on biomaterial. A rough- and hydrophilic-surface are better for adsorption of specific proteins and promotion of the following biological processes than a smooth- and hydrophobicone. This paper discusses the effect of surface mechanical attrition treatment (SMAT) on the roughness andwettability of AIS1316L. The polished samples were treatedfor 0 - 20 minutes. The result shOtt'sthat SMA Tprocess enhances surface roughness and decreases droplet contact-angle. Increasing of SMAT duration enhances microhardness of the sample's surface and subsurface, and yields a relatively smooth surface that reduces hydrophilicity of A/SI316L.
Effects of elastic therapeutic taping on motor function in children with motor impairments: a systematic review

Abstract Background: The elastic therapeutic taping has been considered a promising resource for disabled children. Objective: To systematically review the evidence of the effects of elastic therapeutic taping on motor function in children with motor impairments. Method: Three independent evaluators conducted searches in electronic databases (MEDLINE/PubMed, Scopus, LILACS, BIREME/BVS, Science Direct, SciELO, and PEDro). Clinical studies design, published until 2016, involving elastic therapeutic taping and children aged 0–12 years with motor impairments were included. The variables considered were the methodological aspects (study design, participants, outcome measurements, and experimental conditions); results presented in the studies, and also the methodological quality of studies. Results: Final selection was composed by 12 manuscripts (five randomized controlled trials), published in the last 10 years. Among them, cerebral palsy (CP) was the most recurrent disorder (n = 7), followed by congenital muscular torticollis (n = 2) and brachial plexus palsy (n = 2). Positive results were associated with taping application: improvement in the upper limb function, gross motor skills, postural control, muscular balance, and performance in the dynamics functional and daily activities. Limitations: Lower quality of the studies, clinical and population heterogeneity existed across studies. Conclusions: The elastic therapeutic taping has been shown to be a promising adjunct resource to the conventional rehabilitation in children with motor impairments. However, high methodological studies about its efficacy in this population are already scarce. Implications for Rehabilitation Elastic therapeutic taping has been shown to be a promising adjunct resource to the conventional rehabilitation in disabled children. Clinical trials have indicated improvement in the postural control and functional activities with both, upper and lower limbs, and increase in the functional independency resulting from the taping use. Randomized control trials and well-established protocols are needed to increase the confidence in applying elastic therapeutic taping to specific clinical conditions.
The fifth epidermal growth factor like region of thrombomodulin alleviates LPS-induced sepsis through interacting with GPR15

Summary Thrombomodulin (TM) exerts cytoprotection via the fifth region of epidermal growth factor (EGF)-like domain of TM (TME5) by interacting with G-protein coupled receptor 15 (GPR15) expressed on cell surface of vascular endothelial cells. TM is also implied to mediate anti-inflammatory functions by unknown mechanism. By applying a lipopolysaccharide (LPS)-induced murine sepsis model, we assessed the role of TME5 in septic inflammation and coagulation. We found that TME5 treatment protected mice in association with ameliorating inflammation and coagulopathy in LPS-induced sepsis. Further study confirmed that TME5 bound GPR15 in vitro. Knock out of GPR15 abolished protective role of TME5 in sepsis model. GPR15 mediated anti-inflammatory function of TME5 through suppression of phosphorylation of IκBα, nuclear translocation of NF-κB and release of pro-inflammatory cytokines in macro-phages (Macs). Knock out of GPR15 resulted in dysregulated immune response of Macs, characterised by excessive expression of pro-inflammatory genes and failing to limit immune response. This study indicates that TME5 exerts anti-inflammatory function through inhibition of NF-κB in a GPR15-dependent manner. The use of TME5 may be a potential therapeutic option for treatment of sepsis. Supplementary Material to this article is available online at www.thrombosis-online.com.
The electric strength of some synthetic polymers

The intrinsic electric strengths of polythene, polystyrene, polyisobutene, polymethyl methacrylate, chlorinated polythene and oxidized polythene have been measured over the temperature range -200° to + 110°C. At low temperatures the electric strengths of the non-polar polymers, polythene, polystyrene, and polyisobutene, do not vary much with temperature; for each of them there is a characteristic temperature above which the electric strength falls rapidly with further temperature rise. This temperature is about 40° C for polythene, 90° C for polystyrene, and -50° C for polyisobutene. The electric strength of the polar polymer, polymethyl methacrylate, is much higher than those of the non-polar polymers at low temperatures, and falls with increasing temperature throughout the temperature range investigated; there is an increased rate of change of electric strength with temperature above 20° C. Mild chlorination of polythene leads to an increase in the electric strength at low temperatures, a decrease at high temperatures, and a lowering of the temperature at which the temperature gradient changes. At low temperatures the electric strength of oxidized polythene is greater than the corresponding strength of unoxidized polythene. The results are discussed in the light of Froohlich's electronic theory of breakdown.
Convolutional neural networks with low-rank regularization

Large CNNs have delivered impressive performance in various computer vision applications. But the storage and computation requirements make it problematic for deploying these models on mobile devices. Recently, tensor decompositions have been used for speeding up CNNs. In this paper, we further develop the tensor decomposition technique. We propose a new algorithm for computing the low-rank tensor decomposition for removing the redundancy in the convolution kernels. The algorithm finds the exact global optimizer of the decomposition and is more effective than iterative methods. Based on the decomposition, we further propose a new method for training low-rank constrained CNNs from scratch. Interestingly, while achieving a significant speedup, sometimes the low-rank constrained CNNs delivers significantly better performance than their non-constrained counterparts. On the CIFAR-10 dataset, the proposed low-rank NIN model achieves $91.31\%$ accuracy (without data augmentation), which also improves upon state-of-the-art result. We evaluated the proposed method on CIFAR-10 and ILSVRC12 datasets for a variety of modern CNNs, including AlexNet, NIN, VGG and GoogleNet with success. For example, the forward time of VGG-16 is reduced by half while the performance is still comparable. Empirical success suggests that low-rank tensor decompositions can be a very useful tool for speeding up large CNNs.
GROWTH AND YIELD OF OYSTER MUSHROOM (PLEUROTUS OSTREATUS) AS AFFECTED BY GRAM POWDER AMENDMENT IN SUBSTRATE

The effect of gram powder on growth and yield of oyster mushroom (Pleurotus ostreatus (Jacq. Ex. Fr.) Kummer) was studied after preparation of pure culture on PDA, spawn on sorghum grains and cultivation on banana leaves amended with 0.0, 0.5, 1.0, 1.5, 2.0 and 2.5% gram powder. The growth and yield recorded significantly earlier and better as the gram powder was increased. The earlier completion of spawn running, appearance of pinheads, maturation of fruiting bodies and period between flushes, maximum number of bunches of fruiting bodies, fruiting bodies itself and number of flushes, higher yield, maximum biological efficiency (BE) and minimum contamination was observed in case of amending 2.5 or 2.0% gram powder followed by 1.5 and 1.0% gram powder, whereas, poor performance was recorded in case of control, followed by the lowest dose of gram powder (0.5%), even 100% substrate was found contaminated (96 days after spawn running).
Individual Differences in Verbal Working Memory Underlie a Tradeoff Between Semantic and Structural Processing Difficulty During Language Comprehension: An ERP Investigation

This study investigated the processes reflected in the widely observed N400 and P600 event-related potential (ERP) effects and tested the hypothesis that the N400 and P600 effects are functionally linked in a tradeoff relationship, constrained in part by individual differences in cognitive ability. Sixty participants read sentences, and ERP effects of semantic anomaly, relative to plausible words, were calculated for each participant. Results suggested qualitatively different ERP patterns across participants: Some individuals generated N400-dominated effects, whereas others generated P600-dominated effects, for the same stimuli. To specify the sources of individual differences in brain responses, we also derived aggregate scores for verbal working memory (WM), nonverbal WM, and language experience/knowledge, based on 6 behavioral measures administered to each participant. Multiple regression analysis pitting these 3 constructs against each other showed that a larger verbal WM capacity was significantly associated with larger P600 and smaller N400 effect amplitudes across individuals, whereas the other constructs did not predict the ERP effects. The results suggest that N400 and P600 brain responses, which may be attributable to semantic integration difficulty and structural processing, respectively, vie for expression when comprehenders encounter semantically unexpected words and that which option wins out is constrained in part by each comprehender’s verbal WM capacity.
The effects of socioecological factors on variation of communicable diseases: A multiple-disease study at the national scale of Vietnam

Objective To examine the effects of socioecological factors on multiple communicable diseases across Vietnam. Methods We used the Moran’s I tests to evaluate spatial clusters of diseases and applied multilevel negative binomial regression models using the Bayesian framework to analyse the association between socioecological factors and the diseases queried by oral, airborne, vector-borne, and animal transmission diseases. Results and significance The study found that oral-transmission diseases were spatially distributed across the country; whereas, the airborne-transmission diseases were more clustered in the Northwest and vector-borne transmission diseases were more clustered in the South. Most of diseases were sensitive with climatic factors. For instance, a 1°C increase in average temperature is significantly associated with 0.4% (95CI, 0.3–0.5), 2.5% (95%CI, 1.4–3.6), 0.9% (95%CI, 0.6–1.4), 1.1% (95%CI), 5% (95%CI, 3-.7.4), 0.4% (95%CI, 0.2–0.7), and 2% (95%CI, 1.5–2.8) increase in risk of diarrhoea, shigellosis, mumps, influenza, dengue, malaria, and rabies respectively. The influences of socio-economic factors on risk of communicable diseases are varied by factors with the biggest influence of population density. The research findings reflect an important implication for the climate change adaptation strategies of health sectors. A development of weather-based early warning systems should be considered to strengthen communicable disease prevention in Vietnam.
Plasmid-Mediated Quinolone Resistance Genes and Antibiotic Residues in Wastewater and Soil Adjacent to Swine Feedlots: Potential Transfer to Agricultural Lands

Background: Inappropriate use of antibiotics in swine feed could cause accelerated emergence of antibiotic resistance genes, and agricultural application of swine waste could spread antibiotic resistance genes to the surrounding environment. Objectives: We investigated the distribution of plasmid-mediated quinolone resistance (PMQR) genes from swine feedlots and their surrounding environment. Methods: We used a culture-independent method to identify PMQR genes and estimate their levels in wastewater from seven swine feedlot operations and corresponding wastewater-irrigated farm fields. Concentrations of (fluoro)quinolones in wastewater and soil samples were determined by ultra-performance liquid chromatography–electrospray tandem mass spectrometry. Results: The predominant PMQR genes in both the wastewater and soil samples were qnrD, qepA, and oqxB, whereas qnrS and oqxA were present only in wastewater samples. Absolute concentrations of all PMQR genes combined ranged from 1.66 × 107 to 4.06 × 108 copies/mL in wastewater and 4.06 × 106 to 9.52 × 107 copies/g in soil. Concentrations of (fluoro)quinolones ranged from 4.57 to 321 ng/mL in wastewater and below detection limit to 23.4 ng/g in soil. Significant correlations were found between the relative abundance of PMQR genes and (fluoro)quinolone concentrations (r = 0.71, p = 0.005) and the relative abundance of PMQR genes in paired wastewater and agricultural soil samples (r = 0.91, p = 0.005). Conclusions: Swine feedlot wastewater may be a source of PMQR genes that could facilitate the spread of antibiotic resistance. To our knowledge, this is the first study to examine the occurrence of PMQR genes in animal husbandry environments using a culture-independent method.
