Properties and specificity of a cell-wall proteinase from Lactobacillus helveticus

A cell-wall proteinase activity was extracted from cells of Lactobacillus helvetieus grown on MRS medium. The enzyme was characterized after DEAE-Trisacryl chrornatography and gel filtration on Ultrogel AcA 34 column. Two proteolytic fractions of different molecular weights were isolated. Their enzyme properties and specificity were clearly similar indicating that these fractions represented the same enzyme. It is a serine proteinase displaying optimum activity at pH 7.5-8.0 and 42 oc. Peptide bonds cleaved in œs l and {3casein had no corn mon feature and no clear specificity can be defined. The six main peptides obtained after {3-casein hydrolysis were identified (Arg.-Leug, HisI06-PheI19, LYS'~6-GlnlSZ' ArglsrPhel9o, LeuI9,-Valzo9' TyrI93-VaIZ09) as weil as the two peptides liberated from œs l-casein (Arg.-Ilec, Arg.-Glus). These peptides whose size varies between 6 and 19 residues have probably to be hydrolysed by membrane-bound peptidases prior to their transport through the cytoplasmic membrane. Sorne of those released from the Cterminal part of {3-casein are potentially bitter.
The MOSDEF Survey: A Stellar Mass–SFR–Metallicity Relation Exists at z ∼ 2.3

We investigate the nature of the relation among stellar mass, star formation rate, and gas-phase metallicity (the –SFR–Z relation) at high redshifts using a sample of 260 star-forming galaxies at z ∼ 2.3 from the MOSDEF survey. We present an analysis of the high-redshift –SFR–Z relation based on several emission-line ratios for the first time. We show that a –SFR–Z relation clearly exists at z ∼ 2.3. The strength of this relation is similar to predictions from cosmological hydrodynamical simulations. By performing a direct comparison of stacks of z ∼ 0 and z ∼ 2.3 galaxies, we find that z ∼ 2.3 galaxies have ∼0.1 dex lower metallicity at fixed and SFR. In the context of chemical evolution models, this evolution of the –SFR–Z relation suggests an increase with redshift of the mass-loading factor at fixed , as well as a decrease in the metallicity of infalling gas that is likely due to a lower importance of gas recycling relative to accretion from the intergalactic medium at high redshifts. Performing this analysis simultaneously with multiple metallicity-sensitive line ratios allows us to rule out the evolution in physical conditions (e.g., N/O ratio, ionization parameter, and hardness of the ionizing spectrum) at fixed metallicity as the source of the observed trends with redshift and with SFR at fixed at z ∼ 2.3. While this study highlights the promise of performing high-order tests of chemical evolution models at high redshifts, detailed quantitative comparisons ultimately await a full understanding of the evolution of metallicity calibrations with redshift.
Determinants of Types of Underemployment in the MiDA Intervention Zones of Ghana

Underemployment is a severe form of human resource underutilization, especially in the rural areas of Ghana. Unfortunately while its ‘twin brother’ , unemployment, had for many years enjoyed some attention in the world of research, much cannot be said of underemployment. Using labour underutilization framework, the pape r employs multinomial logistic regression to investig ate empirically the various forms of underemployment and their determinants in the three MiDA intervention z ones in Ghana. The empirical analysis was done with the data of the Ghana Living Standard Survey Five Plus (GLSS 5+) and factors such as: experience, employment in the manufacturing sector and settlement in an urban loc ation tend out not to be in support of underemploym ent. Consistent with findings of previous studies, the s tudy found all forms of underemployment to be highl y pervasive in the rural areas. Unexpectedly, acquisi tion of tertiary academic qualification was found t o exacerbate the incidence of underemployment. Suggestion was therefore made to the stakeholders of the Ghanaian ec onomy to develop pragmatic measures to address the proble m of labour underutilization, especially those invo lving graduates of tertiary institutions, in order not to discourage Ghanaians from seeking higher academic laurels.
More thought - more framing effects? : Framing effects as a function of elaboration

Three studies investigate the impact of the amount of elaboration on framing effects. In all three studies, participants were exposed to decision scenarios similar to the 'Asian disease' problem (Tversky & Kahneman, 1981). The results replicated previous findings: Participants avoided the risky option when the scenario was framed in terms of gains, but preferred the risky option when the scenario was framed in terms of losses. Most importantly, these effects were most pronounced when participants spent more time working on the decision, because of either increased elaboration time (Study 1 and 2) or increased processing motivation (Study 3). Moreover, increased elaboration increased framing effects only when the situation required the scenario to be enriched with additional information. The discussion focuses on the possibility that increased elaboration may not necessarily result in less bias in social judgment and decision making.
Endurance Exercise Training Attenuates the up Regulation of iNOS in the Skeletal Muscles of Chronic/Progressive Mouse Model of Parkinson’s Disease

Background: Parkinson ’ s disease (PD) is one of the most common neurodegenerative diseases in the elderly. PD complications include muscle weakness and fatigue, these complications lead in part to decrease the endurance of PD patients. Strength of skeletal muscles has a major role in ADL performance, which is one of the challenges that PD patients have. The main goals of this study are to study the expression of inducible nitric oxide synthase (iNOS) in the skeletal muscles of PD and to examine the effect of treadmill exercise training on iNOS expression in these skeletal muscles. Methods : Twenty normal albino mice and 20 albino mice with 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP) -induced PD were divided into four groups: sedentary control (SC), exercised control (EC), sedentary PD (SPD), and EPD (EPD). Parkinsonism was induced by injections of 10 doses of MPTP (25 mg/kg) and probenecid (250 mg/kg) over 5 weeks . After the completetion of treadmill exercise training, samples from the gastroc and soleus muscles were evaluated by immunohistochemistry to examine the expression of iNOS in the four groups of animals. Results: Expression of iNOS in gastrocnemius muscle showed significant increase in expression of iNOS is SPD group compared to SC, # P value < 0.05. In soleus muscle, there was an increase in expression of iNOS is SPD group compared to SC, but the change was not significant, P value < 0.08. Also, exercise did not significantly decrease the expression of iNOS in Parkinsonian group P value < 0.13. Conclusion: Our present data suggest that endurance exercise training reduces PD-induced alterations in iNOS expression in skeletal muscles. These results might be important in considering rehabilitation protocols for PD and its related pathophysiology. J Neurol Res. 2013;3(3-4):108-113 doi: https://doi.org/10.4021/jnr217w
Cultivation of Oyster Mushroom (Pleurotus HK-37) On Solid Sisal Waste Fractions Supplemented With Cow Dung Manure

Solid sisal waste fractions which included composted sisal boles and sisal leaves decortication residues supplemented with cow dung manure at various rates used singly and/or in combination as substrates were investigated for cultivation of oyster mushroom ( Pleurotus HK-37). The effect of the test sisal waste substrates and cow dung manure of various supplementation rates were evaluated by mushroom yield, biological efficiency and mushroom size. Pinheads occurred in all substrates within 3 to 5 weeks of transfer of bags to the cropping room. The overall best results of mushroom production were obtained in a substrate combination of 50 % sisal leaves + 50 % sisal boles (based on 450 g wet weight substrate) supplemented by 30 % cow dung manure with the mushroom yield of 184.64 g fresh mushrooms/kg moist substrate weight and percentage biological efficiency (B.E) of about 63 %. Mushroom size of 6.10 was obtained in sisal boles substrate supplemented by 20 % cow dung manure. Least yield of 26.73 g fresh mushrooms/kg moist substrate weight and lowest B.E of 8.95 % were obtained from non-supplemented substrate of sisal leaves alone. The study concluded that, supplementation using cow dung manure may play an important role on increasing the yield and productivity of Pleurotus HK-37 on solid sisal waste fractions under the conditions investigated.
Ambulatory blood pressure as a predictor of cardiovascular risk

Hypertension is one of the most common primary diagnoses and a known risk factor for cardiovascular disease, stroke and kidney disease. Like many other physiological variables, blood pressure is characterized by long- and short-term variability. Thus, blood pressure measured over extended periods of time, i.e. ambulatory monitoring, is more representative of the actual value than a single office reading. In longitudinal studies, ambulatory blood pressure (ABP) is found to predict future cardiovascular risk better than conventional blood pressure. Not only blood pressure values but also the pattern predicts cardiovascular risk on ABP measurement. Non-dipping blood pressure pattern, i.e. nighttime/daytime pressure greater than 0.9, is an independent risk factor for cardiovascular events. Ambulatory blood pressure is vital for identifying specific conditions such as white coat hypertension, masked hypertension, and apparent drug resistance. Recognizing these conditions is important considering the fact that they have significantly different prognosis than predicted from conventional office readings in each condition.
Conspiracy Theorists and Monological Belief Systems

Recent scholarship has claimed to show that conspiracy theorists are prone to simultaneously believe mutually contradictory conspiracy theories, as well as believe entirely made up conspiracy theories. The authors of those studies suggest that this supports the notion that conspiracy theories operate within “monological belief systems”, in which conspiracy theorists find support for conspiratorial beliefs in other conspiratorial beliefs, or in related generalizations, rather than in evidence directly relevant to the conspiracy in question. In this article, I argue that all of that is either wrong or at least misleading.
Prediction of prolonged mechanical ventilation in patients in the intensive care unit A cohort study

Introduction: There are no established guidelines for selecting patients for early tracheostomy. The aim was to determine the factors that could predict the possibility of intubation longer than 7 days in critically ill adult patients. Methods: This is cohort study made at a general intensive care unit. Patients who required at least 48 hours of mechanical ventilation were included. Data on the clinical and physiologic features were collected for every intubated patient on the third day. Uni- and multivariate statistical analyses were conducted to determine the variables associated with extubation. Results: 163 (62%) were male, and the median age was 59±17 years. Almost one-third (36%) of patients required mechanical ventilation longer than 7 days. The variables strongly associated with prolonged mechanical ventilation were: age (HR 0.97 (95% CI 0.96-0.99); diagnosis of surgical emergency in a patient with a medical condition (HR 3.68 (95% CI 1.62-8.35), diagnosis of surgical condition-non emergency (HR 8.17 (95% CI 2.12-31.3); diagnosis of non-surgical-medical condition (HR 5.26 (95% CI 1.85-14.9); APACHE II (HR 0.91 (95% CI 0.85-0.97) and SAPS II score (HR 1.04 (95% CI 1.00-1.09) The area under ROC curve used for prediction was 0.52. 16% of patients were extubated after day 8 of intubation. Conclusions: It was not possible to predict early extubation in critically ill adult patients with invasive mechanical ventilation with common clinical scales used at the ICU. However, the probability of successfully weaning patients from mechanical ventilation without a tracheostomy is low after the eighth day of intubation.
Modulation of cell-wall bound phenolics accumulation by shikimate pathway in yeast extract elicited fragrant roots of Hemidesmus indicus

Plant cell walls contain various phenolic compounds, originated from phenylpropanoid pathway. Hemidesmus indicus is a well-known tropical Indian medicinal plant, traditionally used as herbal medicine for different ailments. Several reports have been published on its soluble phenolic constituents so far. Recently, shikimate pathway modulated biosynthesis of 2-hydroxy-4mrthoxybenzaldehyde, a major soluble phenolic compound of H. indicus, has been demonstrated. Here we have reported three major cell-wall bound phenolic compounds (4-hydroxybenzoic acid, 4-coumaric acid and ferulic acid) in the fragrant Hemidesmus indicus root. We described their accumulation pattern in quantitative manner by high performance liquid chromatographic analysis before and after elicitation with yeast extract and correlation of their accumulation with shikimate pathway by inhibition with glyphosate treatment.
Atomic Force Microscopy Studies of Langmuir-Blodgett Films of Cytochrome P450scc: Hemeprotein Aggregation States and Interaction with Lipids

Tapping mode atomic force microscopy was applied for a study of the molecular organization and aggregation states of purified bovine adrenocortical cytochrome P450scc present in thin solid films. The films of pure cytochrome P450scc or cytochrome P450scc mixed with lipids were transferred onto substrates of highly oriented pyrolytic graphite or mica. Images of the cytochrome P450scc films show that the topology of the proteins is drastically dependent on surface pressure. An effect of hemeprotein on the structural organization of lipid was observed. Images of the hemeprotein molecules and/or their aggregates provide a new insight for the further understanding of the nature of hemeprotein-hemeprotein and hemeprotein−lipid interactions as well as the membrane topology of cytochrome P450scc.
Educational Choices and Educational Traps

From a substantive point of view, the paper analyzes the statistical association between individuals' educations and those of their parents in France and in Italy at the beginning of the twenty-first century - a phenomenon for which a comparison specifically focused on these two countries is still lacking. From a theoretical point of view, the paper develops a formal explanatory model of the macro-level structure of educational inequality - the "interdependent educational choice model" (IECM) - which frames educational choices as the result of both individual benefit/cost evaluations and peer-group pressures. It thus enriches the sociological educational rational-choice approach through the economic perspective of the so-called "membership theory of inequality". From a methodological point of view, the paper adopts agent-based simulations as a means to test the explanatory relevance of the IECM. Three groups of results are discussed. First, the paper demonstrates that simulation of the agent-based implementation of the IECM is able to generate a macro-level association between agents' educational backgrounds and their educational outcomes whose basic structure well reproduces all the qualitative aspects of both educational outflows and opportunities observed in France and in Italy at the beginning of the twentyfirst century. Second, by analyzing data collected at the agent-level during the simulation, the paper demonstrates that these macro-level patterns are produced on the basis of micro- and relational-level regularities which qualitatively mimic the real-world counterparts for which we have (at least, partial) empirical evidence. Finally, by manipulating the characteristics of the artificial network in which agents are embedded, the paper demonstrates that the IECM generates a realistic macro-level structure of educational inequalities on the basis of a cumulative process in which highly educationally-homophilic ego-centred dyadic networks fuel educational traps that progressively amplify the initial within- and between-group heterogeneity in agents' perceptions of the benefits and costs of educational levels. Overall, the paper is a preliminary attempt to create, within the sociology of stratification and social mobility, an interface among formal theoretical modelling, the quantitative analysis of empirical data, and computational techniques.
Comparing traditional and remote interpreting in police settings: quality and impact factors

Translating and interpreting for society and the institutions means meeting the new language needs characterising everyday life. As a result of growing mobility and constantly increasing migration flows, often institutions are required to communicate with people who speak languages ​​of lesser diffusion in Europe's multicultural and multilingual context. These needs are anche felt in the legal sector. The articles included in this volume show clearly That meeting language needs in the legal sector means guaranteeing citizens' rights and strengthening democracy in our societies. [Source: Editors]
CONDUCTING PRELIMINARY DESIGN AROUND AN INTERACTIVE TABLETOP

Our work lies at the intersection of preliminary design and tabletop groupware. We have constructed our own prototype, named the TATIN table, to begin developing applications for design teams. During the design of our system, through an extensive literature review we have indentified the early preliminary design phase of a project to be the area where interactive tabletops would make the greatest impact. Next, we developed software for group brainstorming sessions and conducted extensive usability experiments using this software. During the experiments, we administered subjective questionnaires and obtained extensive video footage of the session. We present our techniques for the analysis of these videos and report our results on collaboration and communication in this environment.
A SIRS Epidemic Model Incorporating Media Coverage with Random Perturbation

We investigate the complex dynamics of a SIRS epidemic model incorporating media coverage with random perturbation. We first deal with the boundedness and the stability of the disease—free and endemic equilibria of the deterministic model. And for the corresponding stochastic epidemic model, we prove that the endemic equilibrium of the stochastic model is asymptotically stable in the large. Furthermore, we perform some numerical examples to validate the analytical finding, and find that if the conditions of stochastic stability are not satisfied, the solution for the stochastic model will oscillate strongly around the endemic equilibrium.
The generation of vorticity in cosmological N-body simulations

Clustering of a perfect fluid does not lead to the generation of vorticity. It is the collisionless nature of dark matter, inducing velocity dispersion and shell crossing, which is at the origin of cosmological vorticity generation. In this paper we investigate the generation of vorticity during the formation of cosmological large scale structure using the public relativistic N-body code gevolution. We test several methods to compute the vorticity power spectrum and we study its convergence with respect to the mass and grid resolution of our simulations. We determine the power spectrum, the spectral index on large-scales, the amplitude of the peak position and their time evolution. We also compare the vorticity extracted from our simulations with the vector perturbations of the metric. Our results are accompanied by resolution studies and compared with previous studies in the literature.
Wound Healing Effect of an Ointment Made From a Mixture of Brassica oleracea var , Punica granatum , and Plantago major L Extracts in Rats

Results: The average percentage of wound healing in different groups on days 3, 6, 9 and 12 were as follows; 21.3%, 37.87%, 67.39% and 77.17% in control group; 24.98%, 34.21%, 70.74% and 88.55% in positive control group; and 32.35%, 61.27%, 94.53%, and 99.91%, in case group. A significant difference was observed between the control and case groups (P < 0.05). Conclusions: Treatment with the studied ointment could promote wound healing.
Validation of percent body fat using skinfold-thickness, bioelectrical impedance analysis and standard hydrostatic method in male wrestlers

The aim of this present study was to determine and validate the percent body fat through skinfold-thickness and bioelectrical impedance analysis (BIA) using hydrostatic (standardmethod) among male wrestlers in Ahvaz city. To do so, 25 male wrestlers were selectedrandomly (N = 60). Statistical analysis was done using Pearson correlation coefficient, paired T-test, standard error estimation (SEE) and total error (TE). The statistical analysisshows that the skinfold-thickness method used by Lohman for wrestlers has a significantdifference with hydrostatic method (standard method). Also, there was no significantdifference between wrestlers in terms of bioelectrical impedance and standard methodresults (TE = 0.0078, SEE = 0.0071, R = 0.871, P = 0.297). Findings suggest that using BIAis a more suitable method to measure wrestlers’ percent body fat. Key words: Percent body fat, skinfold-thickness, bioelectrical impedance, hydrostatic.
Tube Expansion Deformation Enables In Situ Synchrotron X-ray Scattering Measurements during Extensional Flow-Induced Crystallization of Poly l-Lactide Near the Glass Transition

Coronary Heart Disease (CHD) is one of the leading causes of death worldwide, claiming over seven million lives each year. Permanent metal stents, the current standard of care for CHD, inhibit arterial vasomotion and induce serious complications such as late stent thrombosis. Bioresorbable vascular scaffolds (BVSs) made from poly l-lactide (PLLA) overcome these complications by supporting the occluded artery for 3–6 months and then being completely resorbed in 2–3 years, leaving behind a healthy artery. The BVS that recently received clinical approval is, however, relatively thick (~150 µm, approximately twice as thick as metal stents ~80 µm). Thinner scaffolds would facilitate implantation and enable treatment of smaller arteries. The key to a thinner scaffold is careful control of the PLLA microstructure during processing to confer greater strength in a thinner profile. However, the rapid time scales of processing (~1 s) defy prediction due to a lack of structural information. Here, we present a custom-designed instrument that connects the strain-field imposed on PLLA during processing to in situ development of microstructure observed using synchrotron X-ray scattering. The connection between deformation, structure and strength enables processing–structure–property relationships to guide the design of thinner yet stronger BVSs.
On Decay of Solutions and Spectral Property for a Class of Linear Parabolic Feedback Control Systems

Unlike regular stabilizations, we construct in the paper a specific feedback control system such that u(t) decays exponentially with the designated decay rate, and that some non-trivial linear functionals of u decay exactly faster than . The system contains a dynamic compensator with another state v in the feedback loop, and consists of two states u and v. This problem entirely differs from the one with static feedback scheme in which the system consists only of a single state u. To show the essential difference, some specific property of the spectral subspaces associated with our control system is studied.
