Draft Genome Sequence of Colletotrichum falcatum - A Prelude on Screening of Red Rot Pathogen in Sugarcane

Colletotrichum falcatum, a concealed fungal ascomycete causes red rot, which is a serious disease in sugarcane. It infects economically important stalk tissues, considered as store house of sugar in sugarcane. The study is to find genetic complexities of C. falcatum in establishing this as a stalk infecting pathogen and to decipher the unique lifestyle of this pathogen using NGS technology. We report the draft genome of C. falcatum of about 48.16 Mb in size with 12,270 genes. The genome sequences were compared with other fungal species which revealed that C. falcatum is closely related to C. graminicola and C.sublineola the causal organisms of anthracnose in maize and sorghum. These results brought a new revelation to explore the lifestyle of this unique pathogen which is specialized to infect sugarcane stalk tissues in detail.
Ventilator-associated pneumonia in very low-birth-weight infants at the time of nosocomial bloodstream infection and during airway colonization with Pseudomonas aeruginosa.

PURPOSE To study retrospectively the incidence of ventilator-associated pneumonia (VAP) at the time of Pseudomonas aeruginosa nosocomial bloodstream infection (BSI) and at the time of P aeruginosa airway colonization. MATERIALS AND METHODS Fifteen very low-birth-weight infants who had P aeruginosa BSI and 33 others who did not but who had P aeruginosa airway-colonization were studied. We correlated clinical data, blood cultures (BCs), and tracheal cultures (TCs) with radiologic findings from radio-graphs taken within 2 days before, the day of, and 1 day after BCs or TCs were first positive for P aeruginosa. Chest radiographs were graded by using semiquantitative scores for bronchopulmonary dysplasia and for pneumonia. RESULTS Mean birth weight, gestational age, and age when BC or TC became positive were similar for patients with BSI and colonization. At the time of BSI, 2 infants had airway colonization with P aeruginosa; the TCs of the remaining 13 grew P aeruginosa as a new pathogen. Thirteen of 15 patients with BSI, but none of 33 infants with colonization, died within 2 days of positive BC. VAP was diagnosed in 13 of 15 patients with BSI and in 3 of 33 infants with colonization. CONCLUSION Mechanically ventilated very low-birth-weight infants whose TCs yield P aeruginosa but whose BCs remain negative infrequently have VAP are presumed airway-colonized and are expected to survive. Conversely, VAP is likely to be found when BCs and TCs simultaneously grow P aeruginosa, and high mortality is anticipated.
Hereditary Pancreatitis as the Premalignant Disease: A Japanese Case of Pancreatic Cancer Involving the SPINK1 Gene Mutation N34S

Abstract: Mutations in the cationic trypsinogen gene are acknowledged as a risk factor for pancreatic cancer in patients with hereditary pancreatitis. However, whether patients with mutations in other genes, such as the serine protease inhibitor Kazal type 1 (SPINK1) gene, are also at a higher risk of pancreatic cancer remains unknown. We report a case of pancreatic cancer associated with chronic calcifying pancreatitis in a patient with a homozygous N34S mutation in the SPINK1 gene. A 44-year-old woman was hospitalized due to obstructive jaundice. Preoperative examination showed a tumor in the head of the pancreas and multiple pancreatic stones; pancreatoduodenectomy revealed a solid tumor, 3.0 × 2.5 cm in size, in the head of the pancreas, and numerous pancreatic stones throughout the pancreas. Pathologic studies revealed moderately differentiated tubular adenocarcinoma. Mutational analyses of the SPINK1 and PRSS1 genes in members of the patient’s family were carried out. The homozygous N34S mutation in the SPINK1 gene was found in the patient and her older sister, who was previously diagnosed with chronic calcific pancreatitis and had undergone the Frey operation. The patient’s parents and brother were unaffected carriers of the N34S heterozygous mutation. No family members had any mutations in the cationic trypsinogen gene. To our knowledge, this is the first reported case of chronic pancreatitis accompanied by pancreatic cancer in a patient with the SPINK1 N34S mutation. Although this case does not meet the classic criteria of hereditary pancreatitis, it does suggest that the SPINK1 N34S mutation may be associated with cancer development in patients with hereditary pancreatitis. Further prospective, multicenter trials investigating secondary screening for pancreatic cancer in hereditary pancreatitis are necessary to clarify the role of SPINK1 mutations in the development of pancreatic cancer.
Stability analysis of time-delay systems based on a power of the monodromy operator

This paper studies stability analysis of linear time-invariant time-delay feedback systems consisting of a finite-dimensional system and a pure delay. The continuous-time state transition is described by the monodromy operator in discrete-time through the lifting technique, and a stability condition in terms of its spectral radius is first restated in terms of the norm of a power of the operator. Quasi-finite-rank approximation is then applied on the power of the operator, and by evaluating the effect of the approximation error on the norm, a new necessary and sufficient stability condition is given finally.
Economics of Liability Precaution versus Avoidance

This paper analyses the behaviour of an agent under strict liability and negligence when he can influence both the probability of the accident and the probability of being found liable in case of accident. We aim to compare the normative properties of strict liability versus fault-based liability under such circumstances. The model demonstrates that only a negligence rule is efficient and that the optimal damages under strict liability is less than what is usually admitted in the literature, i.e. the expected fine, given the probability to escape the liability, should be less than the level of harm. Finally, the paper highlights the role played by the technologies of precaution and evasion in the results.
Relationship between aetiology and left ventricular systolic dysfunction in hypertrophic cardiomyopathy

Background Severe left ventricular (LV) systolic dysfunction is an uncommon complication of hypertrophic cardiomyopathy (HCM) that is associated with poor prognosis. Small observational series suggest that patients with rare causes of HCM are more likely to develop systolic impairment than those with idiopathic disease or mutations in cardiac sarcomeric protein genes. The aim of this study was to test this hypothesis by comparing the prevalence of systolic dysfunction and its impact on prognosis in patients with different causes of HCM. Methods and results 1697 patients (52 (40–63) years, 1160 (68%) males) with HCM followed at two European referral centres were studied. Diagnosis of specific aetiologies was made on the basis of clinical examination, cardiac imaging and targeted genetic and biochemical testing. The primary survival outcome was all-cause mortality or heart transplantation (HTx) for end-stage heart failure (HF). Secondary outcomes were HF-related death, sudden cardiac death, stroke-related death and non-cardiovascular death. Systolic dysfunction (LV ejection fraction <50% by two-dimensional (2D) echocardiography) at first evaluation was more frequent in rare phenocopies than in idiopathic or sarcomeric HCM (105/409 (26%) vs 40/1288 (3%), respectively (p<0.0001)). All-cause death/HTx and HF-related death were more frequent in rare phenocopies compared with idiopathic or sarcomeric HCM (p<0.0001). All-cause mortality and HF-related death were highest in patients with cardiac amyloidosis (p<0.0001). Conclusions In adults with HCM, LV systolic dysfunction is more frequent in those with rare phenocopies. When combined with age at presentation, it is a marker for specific aetiologies and is associated with poorer long-term survival.
[Occlusion of a perforating artery, by descending tentorial herniation after head injury, supplying deep cerebral structure--report of 4 cases and their CT evaluation].

Four cases with descending tentorial herniation (DTH) after head injury which showed thalamic, mesencephalic and basal ganglionic low density areas (LDAs) manifesting a infarction in postoperative CT films are reported, and a possible mechanism are discussed in this paper. Case 1: Bilateral acute subdural hematoma with left DTH showed LDAs in the anterior part of the bilateral thalami, left occipital lobe and midbrain. The estimated occluded arteries included the anterior thalamoperforating artery(AThA), posterior cerebral artery and midbrain perforator. Case 2: Right acute epidural hematoma with DTH showed LDAs in the anterior part of the right thalamus and in the left globus pallidus. The estimated occluded arteries included the AThA and anterior choroidal artery. Case 3: Right acute epidural hematoma with DTH showed LDAs in the anterior part of the left thalamus, and in the left midbrain tegmentum. The estimated occluded artery was the interpeduncular thalamoperforating artery (IThA). Case 4: Right chronic subdural hematoma with DTH showed LDA mainly in the left thalamus except for the superior thalamic region. The estimated occluded arteries included the AThA and/or IThA and thalamogeniculate artery. Cases 1 and 4 were adult males and cases 2 and 3 were infant males, and the prognosis was good in the infant males, and poor in the adult males. Each of the 4 cases showed no loss of consciousness just after the head injury while 3 out of them deteriorated within several hours, and one was a case of chronic subdural hematoma.

Expression of Epidermal Growth Factor Receptor in Fetal Mouse Submandibular Gland Detected by a Biotinyltyramide-based Catalyzed Signal Amplification Method

Branching morphogenesis of the fetal mouse submandibular gland (SMG) can be modulated in vitro by stimulation or inhibition of the epidermal growth factor receptor (EGFR). Because the mRNAs for EGF and EGFR are detectable in RNA of SMG rudiments isolated directly from fetuses, the EGF system probably operates physiologically as a regulator of SMG morphogenesis. However, neither EGFR protein nor its precise cellular localization has been characterized in the fetal SMG. Here we show EGFR protein in fetal mouse SMG by immunoprecipitation, affinity labeling, ligandinduced autophosphorylation, and immunohistochemistry. SMGs from E16 fetuses (day of vaginal plug = EO) were labeled with [35S]-cysteine/methionine and homogenized. After addition of specific antibody to EGFR, the immunoprecipitate was isolated, resolved by polyacrylamide gel electrophoresis, and detected by autoradiography. A single band of 170 kD was detected, corresponding to the EGFR protein. Affinity labeling with [125I]-EGF of the membrane fraction of E18 SMG also revealed a prominent band at 170 kD, showing that this EGFR protein can bind specifically to its ligand. Incubation of SMG membranes from E18 fetuses with EGF in the presence of [γ-32P]-ATP, followed by immunoprecipitation with anti-phosphotyrosine antibody also showed a single band at 170 kD, demonstrating autophosphorylation of the EGFR in response to binding of its ligand. Immunohistochemical localization of the cellular sites of EGFR in the fetal SMG required use of a catalyzed signal amplification procedure, with biotinyltyramide as the amplifying agent. EGFR was localized predominantly, if not exclusively, in cell membranes of epithelial cells of the rudiment, whereas staining of mesenchymal cells was equivocal. Staining was strongest on duct cells, and weak on cells of the end-pieces. These findings clearly show that a functional EGFR protein is expressed in fetal SMG chiefly, if not exclusively, on epithelial cells.
Bayesian Source Attribution of Salmonellosis in South Australia

Salmonellosis is a significant cause of foodborne gastroenteritis in Australia, and rates of illness have increased over recent years. We adopt a Bayesian source attribution model to estimate the contribution of different animal reservoirs to illness due to Salmonella spp. in South Australia between 2000 and 2010, together with 95% credible intervals (CrI). We excluded known travel associated cases and those of rare subtypes (fewer than 20 human cases or fewer than 10 isolates from included sources over the 11‐year period), and the remaining 76% of cases were classified as sporadic or outbreak associated. Source‐related parameters were included to allow for different handling and consumption practices. We attributed 35% (95% CrI: 20–49) of sporadic cases to chicken meat and 37% (95% CrI: 23–53) of sporadic cases to eggs. Of outbreak‐related cases, 33% (95% CrI: 20–62) were attributed to chicken meat and 59% (95% CrI: 29–75) to eggs. A comparison of alternative model assumptions indicated that biases due to possible clustering of samples from sources had relatively minor effects on these estimates. Analysis of source‐related parameters showed higher risk of illness from contaminated eggs than from contaminated chicken meat, suggesting that consumption and handling practices potentially play a bigger role in illness due to eggs, considering low Salmonella prevalence on eggs. Our results strengthen the evidence that eggs and chicken meat are important vehicles for salmonellosis in South Australia.
Periovulatory increase in temperature difference within the rabbit oviduct.

BACKGROUND Earlier studies demonstrated a small temperature difference between the sperm storage and fertilization sites within the oviducts of rabbits and pigs. Our aim was to reveal the time dependence of this temperature difference relative to ovulation, and to determine how this difference is generated-by temperature elevation at one of these sites or by temperature decrease at the other site. METHODS The temperature at the sperm storage site (at the isthmus near the uterotubal junction) and at the fertilization site (the isthmic-ampullary junction) of rabbit oviducts were measured before, during, and after ovulation by two probes, connected to digital thermometers. Rectal temperature was constantly measured and served as a control for body temperature. RESULTS The temperature difference between the fertilization site and the storage site was 0.8+/-0.2 degrees C before ovulation. This difference increased at ovulation, reaching 1.6+/-0.1 degrees C after ovulation (P<0.03). This increased difference was mainly due to temperature decrease in the sperm storage site. CONCLUSION The temperature-difference increase within the rabbit oviduct is generated at ovulation by a reduced temperature at the sperm storage site. This temperature gradient may play a role in mammalian reproduction via sperm thermotaxis.
Sleep apnea in sarcoidosis.

BACKGROUND AND AIM OF WORK Sleep apnea is reported to occur in 2-4% of the general population. Patients with sarcoidosis are at increased risk for sleep apnea, possibly due to factors such as steroid use, neurosarcoid, or upper airway obstruction. METHODS In order to determine the prevalence and risk factors for sleep apnea in sarcoidosis patients, we studied 83 consecutive patients with sarcoidosis seen over a six-week time period. Patients were screened using the Epworth Sleepiness Scale questionnaire and the age, sex, race, weight, and medications were recorded. The presence of previously diagnosed sleep apnea, neurosarcoid, lupus pernio, and sinus disease were also noted. A control group of 91 patients seen in general pulmonary clinics were similarly screened. Patients with a positive sleep questionnaire were referred for sleep studies. RESULTS A total of 14 sarcoid patients (17%) were found to have sleep apnea, which was significantly higher than our control group with 3/91 (3%, p < 0.001). The presence of lupus pernio was significantly more frequent in the sleep apnea group. Although 5/51 (10%) female sarcoid patients had sleep apnea, overall it was more frequent in male sarcoid patients. CONCLUSIONS Sleep apnea was frequent in sarcoid patients and was associated with lupus pernio.
The Role of the Social Environment in Household Consumption Decisions in Spain

This article analyses the relationship between household consumption and that in their social environment, defined as those households that live in nearby geographical areas. The results, drawn from the Spanish Household Expenditure Survey, reveal that, on average, approximately one-third of the non-durable goods consumption of the average Spanish household is influenced to some extent by the decisions of its peer group, a magnitude that is in line with the evidence available for other countries. The influence of the social environment appears to be greater for certain specific goods, such as tobacco, clothing, leisure activities and alcohol. This analysis may help us understand how specific shocks, which initially have a direct bearing only on the expenditure of very specific population groups, ultimately affect the consumption of other, broader population groups.
Time-dependence of SI RA neuron response to cutaneous flutter stimulation

Spike discharge activity of RA-type SI cortical neurons was recorded extracellularly in anesthetized monkeys and cats. Multiple applications (trials) of 10-50 Hz sinusoidal vertical skin displacement stimulation ("flutter") were delivered to the receptive field (RF). Analysis revealed large and systematic temporal trends not only in SI RA neuron responsivity (measured as spikes/s and as spikes/stimulus cycle), but also in entrainment, and in phase angle of the entrained responses. In contrast to SI RA neurons, the response of RA skin afferents to comparable conditions of skin flutter stimulation exhibited little or no dynamics. The occurrence and form of the SI RA neuron response dynamics that accompany skin flutter stimulation are shown to depend on factors such as stimulus frequency and the locus of the recording site in the global cortical response pattern. Comparison of recordings obtained in near-radial vs tangential microelectrode penetrations further reveals that the SI RA neuron response dynamics that occur during skin flutter stimulation are relatively consistent within, but heterogeneous across column-sized regions. The observed SI RA neuron response dynamics are suggested to account, in part, for the improved capacity to discriminate stimulus frequency after an exposure ("adaptation") to skin flutter stimulation (Goble and Hollins, J Acoust Soc Am 96: 771-780, 1994). Parallels with recent proposals about the contributions to visual perception of short-term primary sensory cortical neuron dynamics and synchrony in multineuron spike activity patterns are identified and discussed.
Token entrepreneurs: a review of gender, capital, and context in technology entrepreneurship

ABSTRACT This article reviews the literature on gender and entrepreneurship in technology to explore individual and contextual factors maintaining the token status of women in this field. It examines how the intersection of gender and context influences participation rates in entrepreneurship, and suggests that the deeply embedded cultural and cognitive associations that frame both technology and entrepreneurship as masculine concepts create barriers for women when these contexts overlap. It offers a framework for research and practice that aids in the analysis of complex multi-level barriers that control access to the forms of capital necessary for initial and continued participation in technology entrepreneurship. Given calls for women to participate more fully in high-growth technology ventures, it highlights the need for research to incorporate broader analytical perspectives that simultaneously examine both the barriers faced by women in these contexts and the factors that systemically sustain them.
Readmission After Colectomy for Cancer Predicts One-Year Mortality

Objectives:Early hospital readmission is a common and costly problem in the Medicare population. In 2009, the Centers for Medicaid and Medicare Services began mandating hospital reporting of disease-specific readmission rates. We sought to determine the rate and predictors of readmission after colectomy for cancer, as well as the association between readmission and mortality. Methods:Medicare beneficiaries who underwent colectomy for stage I to III colon adenocarcinoma from 1992 to 2002 were identified from the Surveillance, Epidemiology, and End Results-Medicare database. Multivariate logistic regression identified predictors of early readmission and 1-year mortality. Odds ratios were adjusted for multiple factors, including measures of comorbidity, socioeconomic status, and disease severity. Results:Of 42,348 patients who were discharged, 4662 (11.0%) were readmitted within 30 days. The most common causes of rehospitalization were ileus/obstruction and infection. Significant predictors of readmission included male gender, comorbidity, emergent admission, prolonged hospital stay, blood transfusion, ostomy, and discharge to nursing home. Readmission was inversely associated with hospital procedure volume, but not surgeon volume. After adjusting for potential confounding variables, the predicted probability of 1-year mortality was 16% for readmitted patients, compared with 7% for those not readmitted. This difference in mortality was significant for all stages of cancer. Conclusions:Early readmission after colectomy for cancer is common and due in part to modifiable factors. There is a remarkable association between readmission and 1-year mortality. Early readmission is therefore an important quality-of-care indicator for colon cancer surgery. These findings may facilitate the development of targeted interventions that will decrease readmissions and improve patient outcomes.
Nursing students' clinical judgment regarding rapid response: the influence of a clinical simulation education intervention.

AIM The aim of this study was to examine the impact of a novel educational intervention on student nurses' clinical judgment regarding the management of patients experiencing rapid clinical deterioration. METHOD A randomized sample of baccalaureate nursing students enrolled in the final semester of their program at a midwestern public university participated. All students (N = 79) were pretested; the control group (n = 39) was posttested after receiving traditional code blue and rapid response education. The intervention group (n = 40) was posttested after receiving a novel education intervention. RESULTS An independent t-test revealed that nursing students who received the innovative education intervention had significantly higher posttest scores (M = 90.91, standard deviation [SD] = 8.73) than did the nursing students who had not received the intervention (M = 64.80, SD = 19.69), t(77) = 7.65, p <. 001). CONCLUSIONS The findings demonstrate that clinical simulation is effective in improving students' knowledge and clinical judgment, specifically concerning rapid response systems.
Multivariate Almost Stochastic Dominance

Almost stochastic dominance allows small violations of stochastic dominance rules to avoid situations where most decision makers prefer one alternative to another but stochastic dominance cannot rank them. We present the concepts of multivariate almost stochastic dominance and multivariate almost nthâ€ degree risk and their connections with a preference for combining good with bad. Then, we show how a preference for combining good with bad can be applied to obtain various comparative statics results, and we extend our approach to riskâ€ prone (convex) stochastic dominance, which relates to the opposite preference, for combining good with good and bad with bad.
