THE GENETIC COMPOSITION OF PHILAENUS SPUMARIUS POPULATIONS IN ISLAND HABITATS VARIABLY AFFECTED BY VOLES

A rare opportunity to work on coexisting mammal and insect populations in a restrictive environment was afforded to the present authors in connection with studies on island populations of the meadow spittlebug, Phdaenus spumarius (L.). Some of the populations investigated were found to live in meadows simultaneously inhabited by the field vole, Microtus agrestis L. The populations analyzed live on very small islets which are sufficiently isolated to resemble the fenced plots used in certain modern experiments on the ecological genetics of microtine rodents (Krebs et al., 1973). Fencing a vole population destroys the regulatory machinery which normally prevents overgrazing. At peak densities of the M. agrestis populations, the island meadows investigated by us suffer heavily from overgrazing. The present work covers a period of six years, 1969-74, which is enough to allow inclusion of both "overgrazing growth seasons" and recovery seasons. Philaenus spumarius is considered an object in which changes are produced through disturbance of the environment by Microtus agrestis . The phenotypic variable studied in Philaenus is a multiple color polymorphism, the genetic basis of which has recently been unraveled by Halkka et aI. (1973). At most eleven color morphs determined by seven allelic genes plus a small number of modifiers are found in the island populations investigated. In the present work, the phenotypes caused by modifiers are not considered separately but occur under
Identification of toxS, a regulatory gene whose product enhances toxR-mediated activation of the cholera toxin promoter

We describe the cloning of the toxS gene from Vibrio cholerae E1 Tor strain E7946. This gene lies downstream from the toxR gene, which encodes the transcriptional activator for the cholera toxin (ctx) operon in V. cholerae. We show that ToxS acts in conjunction with ToxR to activate expression of the ctx operon in Escherichia coli. The classical strain 569B, which is attenuated for virulance but which synthesizes high levels of cholera toxin in vitro, carries a deletion of 1.2 kilobase pairs of DNA, downstream from the toxR gene, which removes toxS. We present evidence that toxS is the downstream gene in an operon with toxR.

Wireless Measurement System for Extracting Open Loop Micro Coil Parameters

Abstract We report here the wireless extraction of an open ended micro coil inductance L, parasitic capacitance C and resistance R using an inductively coupled passive system which consists of an electrically small magnetic loop antenna as a sensor coil and an open ended test micro coil. Wireless analytical model is developed which includes the gimmick effects generated due to parasitic coupling capacitances. The micro coil parameters i.e. inductance, inter winding capacitance and resistance are extracted from the wirelessly measured impedance signal and then compared with the analytical model. Further the inductively coupled system is simulated using COMSOL multiphyscics in ACDC module.
Pargyline‐Sensitive selective accumulation of a radiolabeled MPTP analog in the primate cerebral cortex and basal ganglia

The distribution of radioiodinated N‐methyl‐4‐(4‐hyroxy‐3‐iodobenzyl)‐1,2,3,6‐tetrahydropyridine (MHTP), an analog of the reportedly nontoxic N‐methyl‐4‐benzyl‐1,2,3,6‐tetrahydropyridine, (4‐homo‐MPTP), has been studied in the primate. [123I]‐MHTP‐derived radioactivity exhibited a progressive accumulation and prolonged retention within the primateeye. Following injection, [123I]MHTP rapidly accumulated within the primate brain and was subssequently oxidized to a radiolabeled metabolite. The half‐life of [123I]MHTP‐derived radioactivity within the primate brain was 50 min. The highest concentrations of radioactivity were found in the caudate‐putamen and the frontal, temproal and cingulate cortices; the substantia nigra and inferior olivary nucleus were labeled with medium intensity. Very low concentrations of radiolabel were detected in the cerebellum and white matter, Selective accumulation of [125I]MHTP‐derived radioactivity within these structures was blocked by pretreatment with pargyline, suggesting that nonoamine oxidase B is involved in the bioactivation of radioiodinated MHTP.

Foeto-placental weight relationship in normal pregnancy and pregnancies complicated by pregnancy induced hypertension and abruption of placentae

Background: The aim of this study was to study the effects of pregnancy induced hypertension and abruption of placenta on foeto-placental weight ratio and its comparison with normal group. Methods: In this comparative study hundred and twenty placentae were collected from labor room and gynecology operation theatre of Liaquat University hospital. Forty placentae from parturient that had pregnancy induced hypertension & forty placentae from parturient with history of Abruption of placenta & forty cases belonged to normal pregnancy (Control group). Fetal weights in all groups were taken along with the weights of placentae and foeto-placental weight was calculated in all groups. Results: Placental parameter weight and diameter of placenta in abruption of placentae and PIH group when compared with control group show highly significant (P <0.001) difference. The weight of the new born in abruption of placentae and PIH group also differs from control group significantly (P = 0.001). The feto-placental ratio is also significant statically in abruption of placentae but not in PIH. Conclusion: Both PIH and abruption of placentae are associated with remarkable changes in placenta such as small placental weight and diameter and as a result low birth weight babies and so altered feto-placental ratio.
Salt Stress Proteins Induced in Listeria monocytogenes

ABSTRACT The ability of Listeria monocytogenes to tolerate salt stress is of particular importance, as this pathogen is often exposed to such environments during both food processing and food preservation. In order to understand the survival mechanisms of L. monocytogenes, an initial approach using two-dimensional polyacrylamide gel electrophoresis was performed to analyze the pattern of protein synthesis in response to salt stress. Of 400 to 500 visible proteins, the synthesis of 40 proteins (P < 0.05) was repressed or induced at a higher rate during salt stress. Some of the proteins were identified on the basis of mass spectrometry or N-terminal sequence analysis and database searching. Twelve proteins showing high induction after salt stress were similar to general stress proteins (Ctc and DnaK), transporters (GbuA and mannose-specific phosphotransferase system enzyme IIAB), and general metabolism proteins (alanine dehydrogenase, CcpA, CysK, EF-Tu, Gap, GuaB, PdhA, and PdhD).
Identifying Diagnostic Test Accuracy Publications using a Deep Model

In this work, we used a deep model architecture to identify DTA studies pertaining to a given review topic. We were provided the list of relevant documents selected based on abstracts and full text for diﬀerent reviews topics. We extracted the abstract and title to be used as features to describe those documents, and learned the deep neural net model that takes as input the abstract and title of the studies, and topic of the review to obtain a binary classiﬁcation of whether that study is a relevant DTA to the review in question.

Personalised face neutralisation based on subspace bilinear regression

Expression face neutralisation helps to improve the performance of expressive face recognition with one single neutral sample in gallery per subject. For learning-based expression neutralisation, the virtual neutral face totally relies on training samples, which removes person-specific characters from the neutralised face. Bilinear kernel rank reduced regression (BKRRR) algorithm is designed in a virtual subspace to simultaneously and efficiently generate both virtual expressive and neutral images from training samples. An expression mask is then established using grey and gradient differences of the two images. The test expression image is transformed to neutral template by piece-wise affine warp (PAW). Using the virtual BKRRR neutral image as source, the PAW image as destination and the area covered by expression mask as clone area, an image fusion strategy based on Poisson equation is then designed, which achieves virtual neutralised face image with person-specific characters preserved. From experiments on the CMU Multi-PIE databases, it could be observed that the neutral faces synthesised by the proposed method could effectively approximate the real ground truth expressive faces, and greatly improve the performance of classic face recognition algorithms on expression variant problems.
Specificity and generalization of perceptual learning in low myopia.

PURPOSE In this study we investigated in observers with low myopia: (i) the pattern of lateral interactions between stimuli activating early cortical analyzers and its modulation by perceptual learning (PL), and (ii) whether PL transferred to untrained stimuli and tasks and whether it exhibits interocular transfer. METHOD Participants (seven adults with low myopia) performed 12 training sessions. Participants were trained on a contrast detection task of a central Gabor target flanked by two co-oriented and co-aligned high contrast Gabor patches. Target-to-flankers separation along the vertical axis was varied from 2 wavelengths (λ) to 8λ. RESULTS The results showed that before PL facilitatory lateral interactions in the myopic eye were reduced in strength, but PL increased contrast sensitivity and improved facilitatory lateral interactions. However, PL did not transfer to different local/global orientations and lower spatial frequencies. On the other hand, PL resulted in an enhancement of the contrast sensitivity function (CSF) and of the uncorrected visual acuity (UCVA) both in the trained and untrained eye. CONCLUSIONS Such improvements seem to be associated to a modulation of lateral interactions between target and flankers and it is likely to take place at a level in which the inputs from the two eyes converge.
Estimación del consumo de macro y micronutrientes en adultos de El Jicarito, Francisco Morazán, Honduras mediante una bases de datos con alimentos procesados de Centroamérica

The objectives were: to determine differences in the estimation of consumption of macro-and micronutrients in adults aged 18-60 years old from El Jicarito, Francisco Morazan, Honduraswhen adding 702 Central America (CA) processed foods to the ESHA database . Also, to determine the effect of adding 702 foods on the estimation of consumption of macro and micronutrients in men vs. women.A completely randomized design was used with a factorial arrangement of 2 (gender) × 2 (databases). Consumption was estimated for: energy, fat, macro and micronutrients based on 24-hour recalls of adults from El Jicarito evaluated by Aguirre (2012). Significant increases (P<0.05) were observed on the estimation of consumption when adding 702 CAfoodsto ESHA database on: energy (43%, up from 1,600 kcal/day ESHA’s database), protein (65%, up from 48 g/day), carbohydrates (39%, up from 260 g/day), total fat (39%, up from 46 g/day), calcium (50%, up from 600 mg/day), iron (45%, up from 11 mg/day). Vitamin C decreased 67% from 96 mg/day. Sodium increased 171% from 2,100 mg/day in men and women (95%, up from 2,000 mg/day). The CA foods added to ESHA database increased the estimation of consumption of energy, protein, carbohydrates, total fat, calcium, iron and decreased vitamin C. The ESHA database with CA food increased the estimation of consumption of dietary fiber and sodium in men more than in women from El Jicarito.
Emotion recognition using ensemble of cepstral, perceptual and temporal features

Despite the great progress made in Artificial Intelligence, the machine couldn't identify the emotional state of the speaker as it is hard for even to human. The research works have been carried out to improve recognition of emotional state of the speaker to achieve better Human Computer Interaction(HCI). Speech samples are characterized by many features and our aim is to define set of features that will significantly contribute to classification of emotions. In our approach we are set to extract few of these features to analyze and use them to classify the emotions. This approach is expected to achieve classification with varying accuracy while trying to classify using each of these features individually. Feature ensemble is adopted to select the features providing greater accuracy and group them together. Experiments a carried out using EMO-DB corpus to analyze the effect of ensemble in SER and found that among the small pool of features, the feature selection and ensemble of cepstral, perceptual and temporal feature provides 12.47% improvement in accuracy compared to better feature among the pool.
Highly linear CMOS RF MMIC amplifier using multiple gated transistors and its Volterra series analysis

CMOS RF MMIC amplifiers are fabricated with linearization technique using multiple gated transistors. At 900 MHz, double and triple gated amplifiers show 2.5-4.5 dB larger figure of merit (linearity-DC power consumption), which means that only 1/2/spl sim/1/3 of DC power is needed to obtain the same OIP/sub 3/ value. Using Volterra series analysis and harmonic balance simulation, it is shown that the linearization technique with the 2nd harmonic termination can increase IIP/sub 3/ by amount of 16 dB max. without additional DC power consumption at optimal bias condition, which can reduce more than 90% of DC power consumption with the same linearity performance.
Folate deficiency causes uracil misincorporation into human DNA and chromosome breakage: implications for cancer and neuronal damage.

Folate deficiency causes massive incorporation of uracil into human DNA (4 million per cell) and chromosome breaks. The likely mechanism is the deficient methylation of dUMP to dTMP and subsequent incorporation of uracil into DNA by DNA polymerase. During repair of uracil in DNA, transient nicks are formed; two opposing nicks could lead to chromosome breaks. Both high DNA uracil levels and elevated micronucleus frequency (a measure of chromosome breaks) are reversed by folate administration. A significant proportion of the U.S. population has low folate levels, in the range associated with elevated uracil misincorporation and chromosome breaks. Such breaks could contribute to the increased risk of cancer and cognitive defects associated with folate deficiency in humans.
Control of lethal browning by using ascorbic acid on shoot tip cultures of a local Musa spp. (Banana) cv. Mzuzu in Tanzania

The use of ascorbic acid during explants preparation and the effect of different concentrations of ascorbic acid in controlling lethal browning and survival of the explants in local banana cv. Mzuzu banana were investigated. The explants were taken from young suckers . The shoot tips were cultured on Murashige and Skoog’s media supplemented with 5 mg/l of benzylaminopurine (BAP) and different concentrations of ascorbic acid (0, 50, 100 and 200 mg/l). Completely randomized design was used in this study. The results indicate that the use of ascorbic acid as an antioxidant during explants preparation significantly reduced the extent of lethal browning and survival of the explants followed by 100 mg/l of ascorbic acid applied directly into the media. Keywords: Micro propagation, surface sterilization, survival of explants, tissue culture African Journal of Biotechnology , Vol 13(16), 1721-1725
The effects of natural weathering on the properties of heat-treated alder wood

The objective of this study was to investigate the effect of natural weathering in ground contact on biological resistance, modulus of rupture, and color stability of heat-treated alder wood. Chemical composition of weathered wood was also studied by FTIR-ATR spectra. Wood stakes were heated at 150, 180, and 200°C for periods of 2, 6, and 10 hours, and the stakes were subsequently exposed to natural weathering and decay in a field area located in the north of Turkey for 3 years. The decay index of heat-treated stakes was lower than that of the controls. The weight loss prevention ratio had an increasing tendency with increasing treatment temperature and length of time. Depending on the treatment parameters, heat treatment reduced the modulus of rupture by up to 50%; however decay caused by soil micro-organisms gave rise to a greater loss of modulus of rupture than heat. Weathering processes caused remarkable color changes in the samples. FTIR-ATR spectra showed significant deformations and degradations in wood components, especially in the hemicelluloses of heat-treated samples. Degradation of hemicelluloses increased with an increase in heat temperature and exposure time.
Timeline of cardiac dystrophy in 3–18‐month‐old MDX mice

The dystrophin‐deficient (mdx) mouse remains the most commonly used model for Duchenne muscular dystrophy (DMD). Mdx mice show a predominantly covert cardiomyopathy, the hallmark of which is fibrosis. We compared mdx and normal mice at six ages (3, 6, 9, 12, 15, and 18 months) using in vivo assessment of cardiac function, selective collagen staining, and measures of TGF‐β mRNA, Evans blue dye infiltration, macrophage infiltration, and aortic wall thickness. Clear temporal progression was demonstrated, including early fragility of cardiomyocyte membranes, which has an unrelated impact on cardiac function but is associated with macrophage infiltration and fibrosis. Aortic wall thickness is less in older mdx mice. Mdx mice display impaired responses to inotropic challenge from a young age; this is indicative of altered adrenoreceptor function. We draw attention to the paradox of ongoing fibrosis in mdx hearts without a strong molecular signature (in the form of TGF‐β mRNA expression). Muscle Nerve, 2010
3D or not 3D: “more is better” or “less is more”? (panel session)

The rapid growth in platform-level support for real-time 3D rendering and animation has recently created an explosion of public interest in adding to the dimensionality of the user interface, and the SIGCHI community has been a major source of activity in this area. This panel considers several points of view on the ever-increasing use of 3D visual representations in the user interface itself. We aim to help distinguish between conditions under which “more” truly is better – from a user-centered perspective – and those in which a well-designed 2D solution would serve as well or even better. Panelists will offer examples of applications in which 3D is highly essential or completely unnecessary
Neuromuscular function and bone geometry and strength in aging

Rantalainen, Timo Neuromuscular function and bone geometry and strength in aging Jyvaskyla: University of Jyvaskyla, 2010, 87 p. (Studies in Sport, Physical Education and Health ISSN 0356-1070; 148) ISBN 978-951-39-3959-5 (PDF), 978-951-39-3948-9 (nid.) Diss. Finnish summary Osteoporosis, falls and ensuing bone fractures cause individual suffering and economical burden. Pharmacological interventions are not cost effective for preventing these osteoporosis and aging related bone fractures, and therefore non-pharmacological interventions, such as exercise should be considered. The purpose of this thesis was to study the associations between body mass, neuromuscular performance (impulse and power in different types of jumps) and skeletal rigidity in both genders and in young and elderly subjects. The results of the studies suggest that tibial rigidity is related to maximal neuromuscular performance in young and elderly men and women. The association between bone rigidity and neuromuscular performance seemed to be moderate, but site and loading specific. Furthermore, neuromuscular performance adds to the predictive power of regression models beyond that of body mass. The difference in the bone rigidity to loading ratio between young and elderly individuals is bigger than one might expect from the delay in bone adaptation alone, indicating changes in skeletal mehcanosensitivity. However, even in the elderly, habitual explosive exercise seems to be associated with more rigid bones. Individual determinants of neuromuscular performance, such as specific tension, may contribute to increasing skeletal integrity and can be positively manipulated with exercises, which have also shown to be effective in fall prevention.
Multiple pulse K-Nearest Neighbors authentication for Malay ECG based class attendance system

This paper introduces a modified version of the k-Nearest Neighbor (kNN) classifier named Multiple Pulse k-Nearest Neighbor (MPkNN). MPkNN is developed by combining the special characteristic of the Pulse Active Width (PAW) technique with kNN. In this work, PAW and MPkNN have been used in a Malay electrocardiogram (ECG) based Class attendance system. A step by step description of generating the new Malay electrocardiogram (ECG) database is also described in this paper. A comparison of a misclassified set of results when using k-NN, with the correct results when using MPkNN is shown in the results section. Overall, PAW and MPkNN manage to correctly identify all subjects in the database during the authentication process. This study presents a novel method of reconfirming classification results using kNN for the same investigated signal.
