Time Series Analysis of Soil Freeze and Thaw Processes in Indiana

Abstract Seasonal cycles of freezing and thawing influence surface energy and water cycle fluxes. Specifically, soil frost can lead to the reduction in infiltration and an increase in runoff response, resulting in a greater potential for soil erosion. An increase in the number of soil freeze–thaw cycles may reduce soil compaction, which could affect various hydrologic processes. In this study, the authors test for the presence of significant trends in soil freeze–thaw cycles and soil temperatures at several depths and compare these with other climatic variables including air temperature, snowfall, snow cover, and precipitation. Data for the study were obtained for three research stations located in northern, central, and southern Indiana that have collected soil temperature observations since 1966. After screening for significant autocorrelations, testing for trends is conducted at a significance level of 5% using Mann–Kendall’s test. Observations from 1967 to 2006 indicate that air temperatures during th.
Genetic Modification of Domestic Animals for Agriculture and Biomedical Applications

Transgenic technology has been applied mainly in the study of gene structure and function in model organisms and gene therapy for human diseases. Transgenic technology has potential for rapidly improving quantity and quality of agricultural products, compared to traditional selection and breeding methods in domestic animals that are time consuming when attempting to alter the desired allele frequency for specific traits. Additionally, transgenic animals can be used as biomedical research models or directly for human health, by producing recombinant pharmaceutical proteins and/or organs for xenotransplantation. Due to the advantage of bypassing the need of embryonic stem (ES) cells that are difficult to isolate in domestic animal species, cell-based method of transgenesis followed by somatic cell nuclear transfer (SCNT) is currently widely applied. However, due to the limitations in making genetic modifications and SCNT, producing genetically modified animals is still inefficient. Fortunately, the current advancement of new techniques and methods in both gene targeting (Urnov et al., 2010) and abilities to produce pluripotent stem cells (Voigt and Serikawa, 2009) holds great promises for this field. In this chapter, we will review the recent progress and technical route of the cell-based method of transgenesis by SCNT and discuss the newly emerging methods to enrich the gene targeting frequency of somatic cells. We will also discuss factors to improve the efficiency of SCNT and our future perspectives on the promises of this field.
Measuring Perceived Social Support in Mexican American Youth: Psychometric Properties of the Multidimensional Scale of Perceived Social Support

The utility of the Multidimensional Scale of Perceived Social Support (MSPSS) (Zimet, Dahlem, Zimet,& Farley, 1988) was investigated within a sample of 290Mexican American adolescents. Results suggested that the three-subscale structure (Family, Friends, and Significant Other) of the MSPSS was confirmed, and adequate internal reliability for the three scales was demonstrated as well. Support for construct validity was found by evaluating correlations from a perceived family support subscale as well as a satisfaction with family measure. It appears that the MSPSS is a useful measure for assessing perceived social support in Latino youth and as such can be used to further our understanding about social support from different sources in Latino adolescents.
Acetylcholinesterase inhibitors for the treatment of dementia in Alzheimer’s disease: do we need new inhibitors?

Acetylcholinesterase inhibitors (AChEIs) have been shown to produce a small, but significant, improvement in cognition in patients with Alzheimer’s disease. However, not all patients respond equally, and cognitive benefit may be of limited duration. Although new AChEIs continue to be developed, more recent studies have been aimed at developing inhibitors that have additional actions separate from AChE inhibition. Importantly, new treatments that target the underlying pathogenic mechanism of Alzheimer’s disease (statins, secretase inhibitors, vaccination) may eventually emerge. These new treatments could make AChEI therapy less relevant for treatment of Alzheimer’s disease.
Evaluation of interleukin-6, tumour necrosis factor-alpha and interleukin-1beta for early diagnosis of neonatal sepsis.

The objective of this study was to assess the contribution of interleukin-6 (IL-6), tumour necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) to an early diagnosis of early-onset neonatal sepsis. A cohort of 117 newborn infants delivered during a 1-y period had IL-6, TNF-alpha and IL-1beta, blood and cerebrospinal fluid (CSF) cultures, leucocyte and platelet count collected on the initial evaluation of possible early-onset sepsis. They were divided into four groups: I, positive blood and/or CSF cultures; II, probably infected with clinical sepsis but negative cultures; III, same as group II but mother received antibiotic antepartum; and IV, newborn infants that did not receive any antibiotic therapy. There were no differences among the four groups with respect to mean gestational ages and birthweights, median Apgar scores, type of delivery, or number of newborn infants with leucocyte count <5000 mm(-3) or >25000 mm(-3), platelet count <100000 mm(-3), immature/total neutrophil ratio >0.2, absolute neutrophil count <1000mm(-3) and median IL-1beta levels. Median IL-6 and TNF-alpha levels were significantly higher in groups with patients with a diagnosis of clinical sepsis than in controls. The optimal cut-off point was 32 pg ml(-1) for IL-6 and 12 pg ml(-1) for TNF-alpha. The combination of both provided a sensitivity of 98.5%. In conclusion, the combination of IL-6 and TNF-alpha is a highly sensitive marker of sepsis in the immediate postnatal period.
An aperture-backed sextuple-mode ultra-wideband bandpass filter

In this paper, a sextuple-mode ring resonator ultra-wideband bandpass filter is presented. The objective is to enhance the selectivity of a quintuple-mode filter by introducing an additional transmission pole within the passband. The extra pole comes from two open stubs inserted symmetrically inside the ring resonator. Analysis of the filter is done to show the relationship between the six resonant frequencies, and characteristic impedance and electrical length of the stubs. The filter is designed, fabricated and measured. The measured responses are in good agreement with simulations. The filter exhibits 108.02% 3dB fractional bandwidth at 6.85GHz centre frequency.
The effect of postmenopausal estrogen therapy on the risk of non-insulin-dependent diabetes mellitus.

OBJECTIVES This study examined the effect of postmenopausal estrogen replacement therapy on the incidence of non-insulin-dependent diabetes in women. METHODS Postmenopausal women aged 50 through 70 years (n=848) without diagnosed diabetes at baseline were followed for 10 to 15 years for incident diabestes. RESULTS Over the average 11.5 year follow-ip, there were 105 new cases of diabetes. The age-adjusted relative-risk for development of diabetes was nonsignificantly lower for women with continuous estrogen replacement therapy use than for never users. After adjustment for major covariates, a nonsignificant linear trend with increasing duration of estrogen replacement therapy was reversed. CONCLUSIONS This study suggests that previous results showing a reduced risk of diabetes in women using estrogen may have been due to selection bias regarding who is prescribed estrogen, confounding factors, or differential diagnostic efforts.
Caecal fermentation and energy accumulation in the rat fed on indigestible oligosaccharides

The energetic contribution from, and effects on the gastrointestinal tract of, indigestible oligosaccharides in growing rats were compared with those of sucrose (S). S and two types of oligosaccharides, fructo-oligosaccharide (Fru) and 6'-galacto-oligosaccharide (Gal) were added to a basal diet at a level of 100 g/kg. The basal diet was given either ad libitum (group B) or at a level approximately 90% of the ad libitum intakes of the Fru and Gal groups (group BR). During a 50 d feeding period, feed intake, digestibilities of nutrients, and digesta retention times using liquid (Co-EDTA) and particulate (Cr-cell-wall constituents) markers were measured. The carcass and the contents of the stomach and caecum were sampled on the last day of the experimental period. There was no significant difference in feed intake between groups other than BR. Addition of Fru and Gal to the basal diet resulted in increased crude ash digestibility and decreased crude protein and fat digestibilities. Mean retention times of digesta markers were increased by addition of Fru and Gal to the diet, and this was associated with enlargement of the caecum. Concentrations and amounts of total organic acids in the caecum were higher in groups Fru and Gal than the other groups. The amount of energy accumulated in the carcass of rats in the Gal group was significantly (P < 0.05) lower than that of rats fed on S but not Fru. Contributions to energy accumulation tended to be different between Fru and Gal; these were associated with differences in composition of caecal organic acids and of fatty acids in body fat.
Complications of plasma exchange

For the past few years, the Canadian Apheresis Study Group has collected data on most apheresis procedures carried out throughout the country. The information accumulated during calendar year 1985 has been reviewed, and the complications that occurred as a result of therapeutic plasma exchange (PE) have been assessed. There were side effects during 612 (12%) of the 5235 procedures done, involving 252 (40%) of the 627 patients treated. The most common reactions were fever, chills, urticaria, muscle cramps, or paresthesias; these reactions were encountered more frequently when plasma was used in the replacement fluid. Most reactions had little or no clinical significance. However, there were 28 severe complications, including one cardiac arrest and two respiratory arrests. Five late deaths occurred, but these were not related directly to PE. Although PE is relatively safe, life‐threatening reactions do occur, and patients require careful observation during the procedure.
Visual Information Processing in the Lion-Tailed Macaque (Macaca silenus): Mental Rotation or Rotational Invariance?

Mental rotation is a widely accepted concept indicating an image-like mental representation of visual information and an analogue mode of information processing in certain visuospatial tasks. In the task of discriminating between image and mirror-image of rotated figures, human reaction times increase with the angular disparity between the figures. In animals, tests of this kind yield inconsistent results. Pigeons were found to use a time-independent rotational invariance, possibly indicating a non-analogue information processing system that evolved in response to the horizontal plane of reference birds perceive during flight. Despite similar ecological demands concerning the visual reference plane, a sea lion was found to use mental rotation in similar tasks, but its processing speed while rotating three-dimensional stimuli seemed to depend on the axis of rotation in a different way than found for humans in similar tasks. If ecological demands influence the way information processing systems evolve, hominids might have secondarily lost the ability of rotational invariance while retreating from arboreal living and evolving an upright gait in which the vertical reference plane is more important. We therefore conducted mental rotation experiments with an arboreal living primate species, the lion-tailed macaque. Performing a two-alternative matching-to-sample procedure, the animal had to decide between rotated figures representing image and mirror-image of a previously shown upright sample. Although non-rotated stimuli were recognized faster than rotated ones, the animal’s mean reaction times did not clearly increase with the angle of rotation. These results are inconsistent with the mental rotation concept but also cannot be explained assuming a mere rotational invariance. Our study thus seems to support the idea of information processing systems evolving gradually in response to specific ecological demands.
Sheep and goat immune responses to nose bot infestation: a review

Oestrus ovis L. (Diptera: Oestridae) is a cosmopolitan agent of myiasis in sheep and goats. The parasitic phase begins after adult females deposit first‐stage larvae (L1) into the nostrils of hosts; these larvae develop into L2 and L3 in the nasal and sinus horn cavities. Sneezing and nasal discharges are the major clinical signs in infected animals. The pathogenesis of O. ovis infection is caused by: (a) the trauma resulting from the mechanical action of spines and hooks during larval movement on mucosal membranes, and, more importantly, (b) an allergenic reaction provoked by molecules excreted/secreted by larvae, of which salivary antigens are those mainly recognized by the host's immune system. The recruitment of immune reactive cells increases gradually from the nasal to sinus cavities in infected hosts. Mast cells, eosinophils, macrophages and lymphocytes are always more numerous in infected than non‐infected animals. Humoral (antibody) systemic response of immunoglobulin G (IgG) usually reaches seroconversion 2–4 weeks post‐first infection and the highest levels are observed during the development of L2 and L3 larvae. Local antibody responses include specific IgG, which has been found to negatively correlate with larval survival and development. Hypersensitivity reaction, immunomodulation, immunization trials and mixed infections of O. ovis and helminths are discussed.
Institutions and Reform

During the past few years, a new wave of reform has been launched under the rubric of reinventing government. Yet, despite the hype, little is known about the extent to which reinventing government is a reality across the country. The authors undertake a systematic analysis of reform activity in a large sample of suburban municipalities and find low rates of adoption of current reforms. Although a number of identifiable and theoretically important institutional constraints inhibit reform activity, city manager leadership appears to be critical for overcoming the impediments to efficient governance.
Workshop on Late Renal Allograft Dysfunction

Despite continued improvement in incidence of acute immune injury and short‐term graft survival, late allograft dysfunction remains a significant problem in the renal transplant population. Recent reports suggest that rates of renal function decline are quite varied in the overall recipient population, and that individual rates for many recipients may not change substantially over time. Moreover, analyses also reveal distinct predictive factors for both early and late functional decline. Long‐term outcome studies for renal transplantation, however, might be significantly limited by incomplete data sets for assessing clinical endpoints. In view of the heterogeneous factors that may cause progressive allograft injury, more routine biopsy sampling would allow a more complete characterization of induced injuries. Elucidating mechanisms of renal fibrosis in response to injury, in experimental systems and humans, is also an important goal in better understanding chronic allograft damage. Regulation of cell senescence genes and epithelial to mesenchymal transition, studied in other models of renal fibrosis, are likely relevant to studies of renal allograft dysfunction. Recent technical advances in analyzing biological samples may play a pivotal role in identifying and validating surrogate markers of allograft function for future interventional trials in transplantation.
Microbiological Transformation of Enrofloxacin by the Fungus Mucor ramannianus

ABSTRACT Enrofloxacin metabolism by Mucor ramannianus was investigated as a model for the biotransformation of veterinary fluoroquinolones. Cultures grown in sucrose-peptone broth were dosed with enrofloxacin. After 21 days, 22% of the enrofloxacin remained. Three metabolites were identified: enrofloxacin N-oxide (62% of the total absorbance), N-acetylciprofloxacin (8.0%), and desethylene-enrofloxacin (3.5%).
An Assessment of the Effectiveness of High Definition Cameras as Remote Monitoring Tools for Dolphin Ecology Studies

Research involving marine mammals often requires costly field programs. This paper assessed whether the benefits of using cameras outweighs the implications of having personnel performing marine mammal detection in the field. The efficacy of video and still cameras to detect Indo-Pacific bottlenose dolphins (Tursiops aduncus) in the Fremantle Harbour (Western Australia) was evaluated, with consideration on how environmental conditions affect detectability. The cameras were set on a tower in the Fremantle Port channel and videos were perused at 1.75 times the normal speed. Images from the cameras were used to estimate position of dolphins at the water’s surface. Dolphin detections ranged from 5.6 m to 463.3 m for the video camera, and from 10.8 m to 347.8 m for the still camera. Detection range showed to be satisfactory when compared to distances at which dolphins would be detected by field observers. The relative effect of environmental conditions on detectability was considered by fitting a Generalised Estimation Equations (GEEs) model with Beaufort, level of glare and their interactions as predictors and a temporal auto-correlation structure. The best fit model indicated level of glare had an effect, with more intense periods of glare corresponding to lower occurrences of observed dolphins. However this effect was not large (-0.264) and the parameter estimate was associated with a large standard error (0.113). The limited field of view was the main restraint in that cameras can be only applied to detections of animals observed rather than counts of individuals. However, the use of cameras was effective for long term monitoring of occurrence of dolphins, outweighing the costs and reducing the health and safety risks to field personal. This study showed that cameras could be effectively implemented onshore for research such as studying changes in habitat use in response to development and construction activities.
Is There a Future for AKT Inhibitors in the Treatment of Cancer?

An AKT inhibitor plus an antiestrogen exhibited no significant clinical activity in patients with ER+/HER2− breast cancer despite laboratory studies supporting an antitumor effect for both drugs combined. These results raise concerns about the development of AKT inhibitors in unselected patients whose tumors have unknown dependence on the PI3K/AKT pathway.

Oxidative Stress and Glycaemic Control in Type 2 Diabetic Patients in Enugu, South-East Nigeria

Background: There is growing evidence that excess generation of highly reactive free radicals, largely due to hyperglycaemia causes oxidative stress, which further exacerbates the development and progression of type 2 diabetes and its complications. Objectives: In this study, the level of oxidative stress was compared with glycaemic control in type 2 diabetic patients. Method: Fifty confirmed type 2 diabetic patients, aged between 25 and 70 years were used for the study. 20 patients with good glycaemic control served as positive control while 20 apparently healthy non-diabetic age-matched individuals served as negative control. The FBS, MDA and HbA1 c were determined in fasting blood samples using standard methods. Results: Patients with poor glycaemic control had significantly raised MDA and HbA1c (P =0.0001) when compared with non diabetics However, those with good glycaemic control only had a significant increase in the MDA when compared to non diabetic. (P =0.0001). ). The MDA level when compared to fasting blood sugar (FBS) and glycated haemoglobin (HbA1c) showed a positive correlation. ( r= 0.77; P = 0.0001 and r=0.69; P = 0.0001 respectively) Conclusion: This study showed that both glycaemic control and lipid peroxidation are factors to be monitored or evaluated in the management of type2 diabetics to avoid the development of diabetic complications.
Discriminant analysis of physiological differences between good and elite distance runners.

Abstract The purpose of this investigation was to evaluate and quantify physiological differences among groups of distance runners. The subjects included 20 elite distance runners (8 marathon, 12 middle-long distance) and 8 good runners. Working capacity and cardiorespiratory function were determined by submaximal and maximal treadmill tests, and body composition by hydrostatic weighing. The variables studied were maximum oxygen uptake ([Vdot]O2 max), [Vdot]O2 submax, lactic acid submax, lean body weight, and fat weight. MANOVA showed that the good runners differed from the elite runners (p < 0.01) and the elite marathon runners differed from the elite middle-long distance runners (p < 0.05). Discriminant analysis showed that both functions were significant. The first was a general physiological efficiency factor that separated the good and elite runners. The second separated the elite marathon and middle-long distance groups. The second function showed that the marathon runners had lower lactic acid subm.
USE OF ONYX IN THE MANAGEMENT OF TENTORIAL DURAL ARTERIOVENOUS FISTULAE

OBJECTIVETentorial dural arteriovenous fistula (DAVF) is an uncommon disease with a poor natural history. Management of tentorial DAVF remains controversial. This study reports the technique and results of transarterial embolization using Onyx (Micro Therapeutics Inc., Irvine, CA) in the treatment of a series of 14 patients with tentorial DAVFs. METHODSWe retrospectively reviewed the clinical and radiological data of 14 patients with tentorial DAVFs who were treated by transarterial embolization using Onyx at Shanghai Changhai Hospital between 2005 and 2008. RESULTSTwelve patients presented with subarachnoid or intraventricular hemorrhage. Complete cure was achieved in 11 patients after 1 procedure and in 1 patient after 2 procedures. Incomplete cure was obtained in the other 2 patients. One patient experienced vessel perforation; another had microcatheter retention. All of the patients recovered well, except 1 patient who died of severe infection caused by ventricular drainage. Clinical follow-up showed no rebleeding or worsening. Follow-up angiography in 8 patients with total occlusion demonstrated no recurrence. CONCLUSIONThese results suggest that transarterial embolization using Onyx is feasible and effective for the management of tentorial DAVFs.
