Comparative Analysis of Screw Loosening With Prefabricated Abutments and Customized CAD/CAM Abutments

Purpose:The aim of this study was to determine the stability of computer-aided design and manufacturing (CAD/CAM) and prefabricated abutment by measuring removal torque before and after cyclic loading. Materials and Methods:Three types of fixture and 2 types of abutments were used. Removable torque was measured after cyclic loading for 5000 cycles between 25 and 250 N for each group. The same procedure was performed twice. Results:First, removal torque values (Newton centimeter) were measured for stock versus custom abutments as follows: group 1: 27.17 versus 26.67, group 2: 26.27 versus 26.33, and group 3: 37.33 versus 36.67. Second removal torque values (Newton centimeter) were also measured: group 1: 23 versus 23.5, group 2: 22.5 versus 22.33, and group 3: 32.67 versus 32.5. There was no significant difference between the stock and custom abutments in either the first or second removal torque values and also no significant difference among initial tightening torque, first or second removal torque (P > 0.05). Conclusion:With precise control of CAD/CAM abutments, good screw joint stability can be achieved.
Pregnancy-induced rhinitis.

BACKGROUND Pregnancy-induced rhinitis (PIR) is often misclassified and under-diagnosed. There is currently no cure or optimum symptomatic treatment. OBJECTIVE To summarize current knowledge of PIR and assess evidence supporting treatment options. TYPE OF REVIEW Structured literature search. SEARCH STRATEGY AND EVALUATION METHOD: Review of English-language articles addressing evidence for aetiology, classification, differential diagnosis or treatment options for PIR. Comparisons to management of other types of rhinitis in pregnancy are also considered. RESULTS Incidence and prevalence of PIR vary widely between studies. Hormonal changes have a presumed aetiological role, although present evidence is scanty. Smoking appears to be the only agreed identifiable risk factor. Distinction between PIR and other types of rhinitis in pregnancy, especially allergic rhinitis, is important as effective treatments differ. Management of PIR focuses on minimal intervention required for symptom relief. CONCLUSIONS Although PIR is temporary, its impact on patients` quality of life can be profound. Advice and conservative treatment provide the mainstay of clinical management. None of the currently available medical options offer an ideal solution. Any potential benefit gained should be balanced against risks to the foetus. Clarifying the definition of this separate category of rhinitis will lead to better recognition, with prompt and appropriate treatment.
Quarterly Real GDP Estimates for China and ASEAN4 with a Forecast Evaluation

The growing affluence of the East and Southeast Asian economies has come about through a substantial increase in their economic links with the rest of the world, the OECD economies in particular. Econometric studies that try to quantify these links face a severe shortage of high-frequency time series data for China and the group of ASEAN4 (Indonesia, Malaysia, Philippines and Thailand). In this paper we provide quarterly real GDP estimates for these countries derived by applying the Chow-Lin related series technique to annual real GDP series. The quality of the disaggregated series is evaluated through a number of indirect methods. Some potential problems of using readily available univariate disaggregation techniques are also highlighted. Copyright © 2004 John Wiley & Sons, Ltd.
Dynamic aspects to current spreading in GGNmosts during current ramp-up

Transient current spreading in GGNmosts during ramp-up is studied using 3D-TCAD and TLP. The peak current density depends on the ratio between the pulse ramp-time and an internal time constant τ. Two design measures are shown that make τ shorter, the peak current density lower, and GGNmosts more robust.
PATERNAL SERUM DIOXIN AND REPRODUCTIVE OUTCOMES AMONG VETERANS OF OPERATION RANCH HAND

We studied whether paternal exposure to Agent Orange and its dioxin contaminant (2,3,7,8-tetrachlorodibenzo-p-dioxin) during the Vietnam War is related to adverse reproductive outcomes after service in Southeast Asia. The index cohort comprises conceptions and children of veterans of Operation Ranch Hand, the unit responsible for aerial spraying of herbicides in Vietnam from 1962 to 1971. The comparison cohort comprises conceptions and children of Air Force veterans who served in Southeast Asia during the same period but who were not involved with spraying herbicides. We found no meaningful elevation in risk for spontaneous abortion or stillbirth. In analyses of birth defects, we found elevations in risk in some organ system categories, which, after review of the clinical descriptions, were found to be not biologically meaningful. There was an increase in nervous system defects in Ranch Hand children with increased paternal dioxin, but it was based on sparse data. We found no indication of increased birth defect severity, delays in development, or hyperkinetic syndrome with paternal dioxin. These data provide little or no support for the theory that paternal exposure to Agent Orange and its dioxin contaminant is associated with adverse reproductive outcomes.
Understanding Phase Transformation in Crystalline Ge Anodes for Li- Ion Batteries

Lithium-ion batteries using germanium as the anode material are attracting attention because of their high-capacity, higher conductivity, and lithium-ion diffusivity relative to silicon. Despite recent studies on Ge electrode reactions, there is still limited understanding of the reaction mechanisms governing crystalline Ge and the transformations into intermediate amorphous phases that form during the electrochemical charge and discharge process. In this work, we carry out in operando X-ray diffraction (XRD) and X-ray absorption spectroscopy (XAS) studies on Ge anodes during the initial cycles to better understand these processes. These two probes track both crystalline (XRD) and amorphous (XAS) phase transformations with potential, which allows detailed information on the Ge anode to be obtained. We find that crystalline Ge lithiates inhomogeneously, first forming amorphous Li9Ge4 during the beginning stage of lithiation, followed by the conversion of the remaining crystalline Ge to amorphous Ge. The li.
Daily stress, coping, and well-being in parents of children with autism: a multilevel modeling approach.

This study used a repeated daily measurement design to examine the direct and moderating effects of coping on daily psychological distress and well-being in parents of children with Autism Spectrum Disorders (ASD). Twice weekly over a 12-week period, 93 parents provided reports of their daily stress, coping responses, and end-of-day mood. Multilevel modeling analyses identified 5 coping responses (e.g., seeking support, positive reframing) that predicted increased daily positive mood and 4 (e.g., escape, withdrawal) that were associated with decreased positive mood. Similarly, 2 coping responses were associated with decreased daily negative mood and 5 predicted increased negative mood. The moderating effects of gender and the 11 coping responses were also examined. Gender did not moderate the daily coping? mood relationship, however 3 coping responses (emotional regulation, social support, and worrying) were found to moderate the daily stress? mood relationship. Additionally, ASD symptomatology, and time since an ASD diagnosis were not found to predict daily parental mood. This study is perhaps the first to identify coping responses that enhance daily well-being and mitigate daily distress in parents of children with ASD.
Two new silicate structures based on a rhodesite-type heteropolyhedral microporous framework.

Two new members of the mero-plesiotype rhodesite series [Sr(2)Na(2)(Si(8)O(19)). 4H(2)O, abbreviated as TR09; SrNa(4)(Si(8)O(19)). 4H(2)O, TR10] have been hydrothermally synthesized in Teflon-lined autoclaves at 503 K and structurally characterized using X-ray diffraction single-crystal data. The crystal structures were solved by direct methods and refined to R = 0.021 [TR09; 3317 reflections with I(o) > 2sigma(I(o))] and R = 0.033 [TR10; 5007 reflections with I(o) > 2sigma(I(o))]. Both structures are based on a rhodesite-type microporous heteropolyhedral framework, where two types of channels are within the double silicate layer that alternates with an ;octahedral' O sheet. The large Sr(2+) cation constrains to the roughly ellipsoidal shape of the channels. The H(2)O molecules are located both in the O sheets and in the channels, where they are loosely hydrogen bonded. The crystal-chemical features that allow flexibility to the rhodesite-type microporous heteropolyhedral framework and make it interesting for possible technological applications are discussed.
Properties and applications of surface wave produced plasmas

2014 Long quiescent, stable and reproducible cylindrical plasma columns can be obtained as a result of the propagation of electromagnetic surface waves. The frequency of these waves is of the order of the electronplasma frequency and it lies in that part (~ 300-4 000 MHz) of the microwave spectrum where power generators with large enough output powers are readily available, at reasonable cost. Moreover, these waves can be excited very efficiently by using appropriate launching structures such as the surfatron. Such plasmas can, in certain instances, advantageously replace the positive column of DC discharges. This paper reviews the properties of the plasma columns sustained by the azimuthally symmetric surface wave. Special attention is given to the radial and axial electron density distributions, as well as to the radial density distributions of excited (radiative and metastable) atoms. Some demonstrated applications as well as further potential applications are also presented. Revue Phys. Appl. 17 (1982) 707-727 NOVEMBRE 1982,
Genes controlling hypothalamic development and sexual differentiation *

Steroid hormones dramatically influence the development of numerous sites in the nervous system. Basic mechanisms in neural development provide foci for understanding how factors related to sex can alter the ontogeny of these regions. Sex differences in neurogenesis, cell migration, cell differentiation, cell death, and synaptogenesis are being addressed. Any and all of these events serve as likely targets for genetic or gonadal steroid‐dependent mechanisms throughout development. Although the majority of sexually dimorphic characteristics in brain have been described in older animals, many hormonal mechanisms that determine sexually differentiated brain characteristics occur during critical perinatal periods. Genes suggested to contribute to the development of specific hypothalamic nuclear groups have rarely been examined in the context of sex. The identification of sex differences in the expression of some of these genes may suggest early and likely transient molecular events that set the stage for later amplification by hormone actions. Sex differences in the positioning of cells in the developing hypothalamus further suggest that cell migration may be one key target for early gene actions that impact long‐term susceptibility to brain sexual differentiation.
Adult Neuroblastoma of the Retroperitoneum and Abdomen: Clinicopathologic Distinction From Primitive Neuroectodermal Tumor

Adult neuroblastoma (ANB) is a rare and poorly recognized entity among a histologically defined group of small, round-cell tumors arising in the retroperitoneum and abdomen. Eight cases of ANB were compared with seven cases of primitive neuroectodermal tumor (PNET) in these locations to identify clinicopathologic features that could be used to distinguish between the two lesions. The ANB study group included four men and four women 22–74 years of age (mean 38 years). Five patients with ANB presented with inflammatory symptoms or elevated levels of catecholamines and their metabolites. Five of the ANB tumors were classified as undifferentiated and three as poorly differentiated with a background of neuropil. These cases often showed immunoreactivity for multiple neural markers such as CD56, chromogranin A, synaptophysin, neurofilament, and neuron-specific enolase, but were negative for CD99, cytokeratins, desmin, myogenin, smooth muscle actin, muscle-specific actin, CD34, S-100 protein, and CD45. In contrast, all of the PNETs were positive for CD99, and four (57%) were also positive for cytokeratins. Two cases of ANB of the undifferentiated subtype had ultrastructural features characteristic of neuroblastoma and lacked a chimeric transcript (EWS-FLI1or ERG), which is specific for PNET. All five patients with the undifferentiated subtype of ANB and six of the seven patients with PNET died of their disease within 3 years of discovery of the lesion. Our results show that ANB, although rare, should be considered in the differential diagnosis of patients with small, round-cell tumors in the retroperitoneum and abdomen. Appropriate immunohistochemical studies and laboratory examination enable pathologists to distinguish ANB from other differential diagnoses, especially PNET.
Identification of a Novel Guanylyl Cyclase That Is Related to Receptor Guanylyl Cyclases, but Lacks Extracellular and Transmembrane Domains*

We have identified a novel guanylyl cyclase, named MsGC-I, that is expressed in the nervous system of Manduca sexta. MsGC-I shows highest sequence identity with receptor guanylyl cyclases throughout its catalytic and dimerization domains but does not contain the ligand-binding, transmembrane, or kinase-like domains characteristic of receptor guanylyl cyclases. In addition, MsGC-I contains a C-terminal extension of 149 amino acids that is not present in other receptor guanylyl cyclases. The sequence of MsGC-I contains no regions that show similarity to the regulatory domain of soluble guanylyl cyclases. Thus, MsGC-I appears to represent a member of a new class of guanylyl cyclases. We show that both a transcript and a protein of the sizes predicted from the MsGC-I cDNA are present in the nervous system of Manduca and that MsGC-I is expressed in a small population of neurons within the abdominal ganglia. When expressed in COS-7 cells, MsGC-I appears to exist as a soluble homodimer with high levels of basal guanylyl cyclase activity that is insensitive to stimulation by nitric oxide. Western blot analysis, however, shows that MsGC-I is localized to the particulate fraction of nervous system homogenates, suggesting that it may be membrane-associated in vivo.
UPTAKE AND RELEASE OF D‐ AND L‐ASPARTATE BY RAT BRAIN SLICES

D‐Aspartate is accumulated by slices of adult rat cortex by a high affinity uptake which is abolished if the sodium ions in the incubation medium are replaced by choline. A small uptake of D‐aspartate takes place if the sodium ions are replaced by lithium ions. It appears likely that D‐aspartate shares the same transport system with L‐aspartate, and that the uptake of D‐aspartate is into the same osmotically‐sensitive particles as those which accumulate L‐aspartate. D‐Aspartate is released from cerebral cortex slices by raised potassium concentrations, provided calcium is present in the perfusing buffer.
Northway virus: a new Bunyamwera group arbovirus from Alaska.

Five Bunyamwera group arbovirus strains were isolated from sentinel rabbits and from mosquitoes belonging to the genera Aedes and Culiseta collected in eastern and central Alaska in 1970–1971. By a serum dilution plaque reduction neutralization test performed in cell cultures, the five strains appear to be identical with each other but different from other North American Bunyamwera group prototype viruses. The name Northway is proposed for this new virus.The significance of Northway virus for use in serologic surveys and ecologic studies is considered briefly.
The effect of natural weathering on untreated wood surface

As a result of contemporary ecological and sustainable movements, a number of constructions from wood, as the only renewable building material, is still increasing. In accordance with these trends, wood elements are often left untreated. The presented study is aimed to characterize and compare a surface degradation of untreated wood caused by weathering. Weathering characteristics of softwoods and hardwoods (spruce, pine, Douglas fir, larch, oak, black locust, maple, poplar and alder) during twelve months of exposure in the climatic conditions of Central Europe were determined. All the wood species were characterized by colour and gloss changes and increasing roughness. The lowest discoloration was observed for oak and the highest one for spruce wood, respectively. The lowest changes of roughness were observed for alder, the highest for spruce wood. The depth of colour changes was relatively similar among the softwoods. Regarding hardwoods, it varied more. The values of total colour changes had a significant correlation with the depth values of these colour changes. Maple, alder and poplar samples were characterized by the presence of mould and blue-stain fungi. Douglas fir wood was found to be the most liable for the formation of cracks.
Awareness and Knowledge of Ovarian Cancer Symptoms and Risk Factors: A Survey of Jordanian Women

Ovarian cancer accounts for 3% of all female cancers and has a high mortality rate among gynecological malignancies. Early diagnosis carries a high survival rate of 93%. So, this study was carried out to assess the knowledge and awareness of Jordanian women about ovarian cancer symptoms and risk factors. A cross-sectional survey design was used; 896 women completed the survey. The mean of total symptoms recognized was low at level of 3.2 (SD = 2.7) out of 10. The three highest known symptoms among women were as follows: extreme fatigue (43.2%), back pain (42.4%), and persistent pain in pelvic area (40.7%). The most commonly known risk factor was smoking (68.4%), followed by having ovarian cyst(s) (59.7%). Hence, with the absence of an effective screening program, a national awareness campaign is urgently needed to improve the public’s understanding of symptoms and risk factors and increasing women’s confidence in symptom recognition.
Architecture of the pulmonary veins: relevance to radiofrequency ablation

BACKGROUND Radiofrequency ablation of tissues in pulmonary veins can eliminate paroxysmal atrial fibrillation. OBJECTIVE To explore the characteristics of normal pulmonary veins so as to provide more information relevant to radiofrequency ablation. METHODS 20 structurally normal heart specimens were examined grossly. Histological sections were made from 65 pulmonary veins. RESULTS The longest myocardial sleeves were found in the superior veins. The sleeves were thickest at the venoatrial junction in the left superior pulmonary veins. For the superior veins, the sleeves were thickest along the inferior walls and thinnest superiorly. The sleeves were composed mainly of circularly or spirally oriented bundles of myocytes with additional bundles that were longitudinally or obliquely oriented, sometimes forming mesh-like arrangements. Fibrotic changes estimated at between 5% and 70% across three transverse sections were seen in 17 veins that were from individuals aged 30 to 72 years. CONCLUSIONS The myocardial architecture in normal pulmonary veins is highly variable. The complex arrangement, stretch, and increase in fibrosis may produce greater non-uniform anisotropic properties.
Video analysis of communication in paediatric consultations in primary care.

BACKGROUND There is a paucity of research evidence concerning communication in paediatric consultations between GPs, adults, and child patients. AIM This study was carried out to identify features of the interaction between a doctor, a child patient aged 6-12 years, and their carer in the consultation associated with the child's participation. DESIGN OF STUDY A qualitative analysis of video recordings of 31 primary care paediatric consultations was undertaken, using strategies from the methodology of conversation analysis. SETTING Primary care, Suffolk, UK. METHOD NHS GPs from three primary care trusts (PCTs), were invited to participate in this study. Sixteen volunteers from this sample took part. RESULTS Analysis of the interaction in the consultations revealed that the children had little involvement. Children participated when invited to do so, and took more time than adults to answer a doctor's question. An adult carer was less likely to answer on behalf of a child, when they were in a position to see that the doctor's gaze was directed at the child, and the doctor addressed the child by name. Adult carers, who had not voiced their own concerns first, were seen to interrupt doctor-child talk. In consultations where the participants sat in a triangular arrangement, all parties being an equal distance apart, triadic talk was noted. CONCLUSION Child involvement in the primary care consultation is associated with adult carers being able to voice their own concerns early in the consultation, and children being invited to speak with the appropriate recipient design.
The Importance of Suspense and Surprise in Entertainment Demand: Evidence from Wimbledon

This paper empirically examines how suspense and surprise affect the demand for entertainment. We use a tennis tournament, the Wimbledon Championships, as a natural laboratory. This setting allows us to both operationalize suspense and surprise by using the audience's beliefs regarding the outcome of the match and observe the demand for live entertainment using TV audience figures. Our match fixed effects estimates of 8,563 minute-by-minute observations from 80 men's singles matches between 2009 and 2014 show that both suspense and surprise are drivers of media entertainment demand. In general, surprise seems to be more important in this regard than suspense, and both factors matter more during a match's later moments. We discuss important implications for the design of entertainment content to maximize entertainment demand.
Drug binding to Sudlow's site I impairs allosterically human serum heme‐albumin‐catalyzed peroxynitrite detoxification

Heme endows human serum albumin (HSA) with globin‐like reactivity and spectroscopic properties. Here, the effect of chlorpropamide, digitoxin, furosemide, indomethacin, phenylbutazone, sulfisoxazole, tolbutamide, and warfarin on peroxynitrite isomerization to NO 3− by ferric HSA‐heme (HSA‐heme‐Fe(III)) is reported. Drugs binding to Sudlow's site I impair dose‐dependently peroxynitrite isomerization by HSA‐heme‐Fe(III). The allosteric modulation of HSA‐heme‐Fe(III)‐mediated peroxynitrite isomerization by drugs has been ascribed to the pivotal role of Tyr150, a residue that either provides a polar environment in Sudlow's site I or protrudes into the heme cleft (i.e., the fatty acid site 1, FA1), depending on ligand occupancy of either sites. © 2010 IUBMB IUBMB Life, 62(10): 776–780, 2010
PROGNOSIS OF SEVERE BRAIN INJURY

The data concerning the mortality in severe brain injury and the disability caused by it were analysed. We classified as severe those head injuries which caused unconsciousness for more than 24 hours. The series presented consists of 204 patients. The follow‐up time was from three to five years. The total mortality was 50 per cent, but increased steeply in older age groups. The mortality in patients over 60 years of age was 78 per cent, but among those under 20 years it was 38 per cent. Three years after the injury 43 per cent of the survivors were totally disabled. Less than 30 per cent of patients over 50 years of age were able to return to their former work, whereas more than 70 per cent of patients under 20 years were able to return to work or to school. It is concluded that in patients over 60 no special or heroic methods of treatment are indicated but that in children and adolescents every effort should be made as long as there has not been respiratory arrest and cerebral death.
