Performance of dental implants after staged sinus floor elevation procedures: 5-year results of a prospective study in partially edentulous patients.

OBJECTIVES The aim of this prospective study was to evaluate the 5-year performance and success rate of titanium screw-type implants with the titanium plasma spray (TPS) or the sand-blasted, large grit, acid-etched (SLA) surface inserted in a two-stage sinus floor elevation (SFE) procedure in the posterior maxilla. MATERIAL AND METHODS A total of 59 delayed SFEs were performed in 56 patients between January 1997 and December 2001, using a composite graft with autogenous bone chips combined with deproteinized bovine bone mineral (DBBM) or synthetic porous beta-tricalcium phosphate (beta-TCP). After a healing period averaging 7.75 months, 111 dental implants were inserted. After an additional 8-14-week healing period, all implants were functionally loaded with cemented crowns or fixed partial dentures. The patients were recalled at 12 and 60 months for clinical and radiographic examination. RESULTS One patient developed an acute infection in the right maxillary sinus after SFE and did not undergo implant therapy. Two of the 111 inserted implants had to be removed because of a developing atypical facial pain, and 11 implants were lost to follow-up and were considered drop-outs. The remaining 98 implants showed favorable clinical and radiographic findings at the 5-year examination. The peri-implant soft tissues were stable over time; the mean probing depths and mean attachment levels did not change during the follow-up period. The measurement of the bone crest levels (DIB values) indicated stability as well. Based on strict success criteria, all 98 implants were considered successfully integrated, resulting in a 5-year success rate of 98% (for TPS implants 89%, for SLA implants 100%). CONCLUSION This prospective study assessing the performance of dental implants inserted after SFE demonstrated that titanium implants can achieve and maintain successful tissue integration with high predictability for at least 5 years of follow-up in carefully selected patients.
Cardiovascular stress reactivity tasks successfully predict the hypotensive response of isometric handgrip training in hypertensives.

This study aimed to determine whether: (a) isometric handgrip (IHG) training lowers resting blood pressure (BP), (b) cardiovascular reactivity to a serial subtraction (SST), IHG (IHGT), and cold pressor (CPT) task predicts this hypotensive response, and (c) cardiovascular reactivity is attenuated posttraining. Resting BP and cardiovascular reactivity to a SST, IHGT, and CPT were measured in 24 hypertensives (51-74 years) before and after 10 weeks of IHG training (n = 12) or control (n = 12). IHG training lowered resting BP (Δ8/5 mmHg), whereby the decrease in systolic BP was correlated to pretraining systolic BP reactivity to the SST (r = -.85) and IHGT (r = -.79; all ps < .01), but not the CPT (r = .34; p > .01). Furthermore, following IHG training, systolic BP reactivity to the SST (Δ7 mmHg) and IHGT (Δ8 mmHg) was reduced (all ps < .01). The results offer promising implications for hypertensives and may provide a tool to identify IHG training responders.
The mucigenous glandular mucosa in the complex stomach of two new‐world camelids, the llama and guanaco

In contrast to the so‐called true ruminants, the compartmentalized stomach of these camelids contained an extensive mucigenous glandular mucosa. This mucosal epithelium was studied with the light and electron microscope. Surface, foveolar, isthmic, and end‐piece regions were identified. Undifferentiated cells with many free ribosomes and few mucigen granules were found in the gland isthmus. More fully differentiated mucigenous cells with fewer free ribosomes, an extensive Golgi complex and a large heterogeneous population of secretory granules were observed in the subjacent end‐piece. These cells were compared with cardiac and other gastric glandular epithelia. The cells in the foveola contained a more extensive granular reticulum, a prominent Golgi complex, and large numbers of mucigen granules and mitochondria. In the upper foveolar cells, large supranuclear and narrow apical accumulations of mucigen granules were separated by an intervening mitochondrial mass. In the tall surface cells there was a diminution in the number of mucigen granules and a concomitant supranuclear massing of mitochondria. Basally, these cells were often separated by prominent intercellular spaces. Effete surface cells were also noted. These lacked desmosomal attachments and sometimes appeared partially extruded. These findings suggested that cells derived from the undifferentiated isthmic cells moved up the foveola and onto the luminal surface. During this migration, these cells appeared to undergo sequential cytologic differentiation. The possible functional significance of these differentiations was considered.
Mechanical properties and bond strength of glass-ionomer cements.

PURPOSE The objective of this study was to evaluate the mechanical properties and bond strength of glass-ionomer cements (GICs) and resin-modified GICs (RM-GICs) that are indicated as restorative materials for the Atraumatic Restorative Treatment (ART) technique. MATERIALS AND METHODS Fifteen disk specimens for the diametral tensile strength (DTS) test and fifteen cylindrical specimens for the compressive strength (CS) test were made of each GIC: Ketac-Fil, Ketac-Molar (ESPE), Fuji IX and Fuji PLUS (GC). Forty human molars were sectioned and embedded in resin with either buccal or lingual surfaces exposed for the tensile bond strength (TBS) test. The surface was ground until a flattened area of enamel or dentin was obtained. After conditioning, inverted truncated cones of GICs were prepared on the flat tooth surfaces. The powder:liquid ratio of Fuji PLUS was adjusted for restorative purposes. Prior to testing, specimens were stored for 24 h (TBS test) and for 1 h, 24 h, and 7 days (CS and DTS tests) in deionized water at 37 degrees C. They were then loaded at a crosshead speed of 1.0 mm/min for CS and 0.5 mm/min for DTS and TBS tests until failure occurred. The data were submitted to two-way ANOVA at 0.05 level of significance, followed by a Tukey-Kramer test for multiple comparisons. RESULTS The mean CS values ranged from 90.27 to 170.73 MPa and DTS means from 6.21 to 22.32, with test periods from 1 h to 7 days. The means for TBS ranged from 4.90 to 11.36 MPa and from 2.52 to 5.55 MPa in enamel and dentin, respectively. No differences were found between materials with the CS test except at 1 hour. The resin-modified GIC (RM-GIC) had the highest DTS, with no changes between the test periods, and the highest TBS for both enamel and dentin. CONCLUSION Among the GICs tested, RM-GIC showed higher values of DTS and TBS.
Global and multiscale aspects of magnetospheric dynamics in local-linear filters

[1] The magnetospheric dynamics consists of global and multiscale components. The local-linear filters (LLFs) relating the solar wind input and the magnetospheric output have been used earlier to predict the global dynamical behavior. In this paper, the relative role of global and multiscale processes in the prediction of magnetospheric dynamics is studied. The filters are derived from the reconstructed input–output magnetospheric phase space using time series of VBS as the input and AL index as the output. We show that the conventional formula for the LLF can be broken into two parts corresponding to the global and multiscale constituents. The first part is the zeroth-order term, which is obtained by the phase space average of the model outputs. This is a feature similar to the mean-field model in phase transition physics, which yields iterative predictions of the global coherent component. The second part consists of the higher-order terms of the filter, which are highly irregular and thus cannot be used in dynamical prediction. This irregular behavior represents the departure from the low-dimensional dynamics underlying earlier studies using LLFs. The earlier prediction studies mixed these two components. However, by separating these two components, the prediction procedure is highly simplified and longer period predictions are achieved. The multiscale nature arises from the perturbations over a wide range of scales and has a power spectrum similar to that of colored noise. When these perturbations are taken into account in the prediction process, the iterative predictions yield a factor of four improvement in the accuracy compared to the mean-field model. However, the filter technique does not provide a prescription for correctly including the multiscale aspects in a dynamical model and further improvement in forecasting can be achieved by a statistical approach. These results have important implications for space weather forecasting.
Small-Cell Carcinoma in the Setting of Pulmonary Adenocarcinoma: New Insights in the Era of Molecular Pathology

Introduction: Transformation into small-cell lung carcinoma (SCLC) has been reported as an evolution of lung adenocarcinoma acquiring resistance to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI). However, spontaneous association of SCLC and adenocarcinoma also exists. We sought to compare patients’ clinical features and mutation status of EGFR in each tumor component in these conditions. Methods: Our study is based on nine consecutive cases of SCLC, occurring synchronously or after a previous diagnosis of pulmonary adenocarcinoma, with or without TKI-based therapy, diagnosed in Marie Lannelongue Surgical Center, France, between 2001 and 2013. Molecular analysis by DNA direct sequencing was performed to detect EGFR mutations on formalin-fixated tissue mostly from surgically resected tumors. Results: Six patients had a metachronous occurrence of SCLC after adenocarcinoma (2 after TKI); three had a synchronous form. There were four combined SCLCs/adenocarcinomas. Seven adenocarcinoma components were EGFR mutated: five exon 19 deletions and two mutations in exon 21 (L833_V834delinsFL and L858R). Four SCLC components were EGFR mutated. Two cases occurred in never-smoker women with adenocarcinoma treated with TKI: one with E872 mutation in exon 21 and one combined SCLC/adenocarcinoma with exon 19 deletion in both components. Two cases were spontaneous: a SCLC with exon 19 deletion occurring after a nonmutated adenocarcinoma and a combined SCLC/adenocarcinoma with exon 21 mutation (L833_V834delinsFL) in both components. Conclusion: SCLC developing in association with adenocarcinoma, either synchronously or metachronously, seem linked to EGFR mutation, regardless of TKI use. Our findings suggest that such associated cases should be tested for EGFR mutations.
Selective enumeration of dairy based strains of probiotic and lactic acid bacteria

Reliable methods for selective enumeration of probiotic and lactic acid bacteria (LAB) are required for improving the functional food quality of probiotics. Various methods were evaluated for selective enumeration of seventeen LAB and probiotic strains. Tested sugars failed to select any species however, improved recovery of total LAB count. The strains were viable and physiologically active within a range of oxygen tension levels, temperature and acidic conditions. Prior methods showed varied results such as De Man Rogosa Sharpe containing bile (MRSB), MRS containing nalidixic acid, paromomycin, neomycin sulphate and lithium chloride (MRS-NPNL), M17 and L. casei (LC) agar failed to select Lactobacillus acidophilus, Bifidobacterium, starter LAB and L. casei strains respectively. However, LC agar appears appropriate for L. paracasei and MRSB for yoghurt starter bacteria in the absence of L. reuteri and L. rhamnosus. The study suggests selective potential of culture media largely depends on target species.
THE PATINATION OF STONE ARTIFACTS

The patination of artifacts made of si licious stone involves certain chemically irreversible processes. Influencing fac tors are: quality and quantity of impuri ties and certain structural aspects of thre stone, nature and mechanism of penetra tion of patination agents, weather and soil conditions. The surface of some silicious stone artifacts, especially flints and cherts, are subject, over a period of time and under certain environmental conditions, to various kinds of chemically induced surface alteration, collectively called "patination". It is of considerable im portance that the archaeologist has a thorough knowledge of both the physical appearance and causative factors involved in these changes since they can be useful in the interpretation of archaeological data.
Population Density and Image Texture: A Comparison Study

The correlation between census population density and Ikonos image texture was explored. The spatial unit for the analysis was census blocks with homogenous land-use. Ikonos image texture was described using three methods: the gray-level co-occurrence matrix (GLCM), semi-variance, and spatial metrics. Linear regression was conducted to explore the correlation between image texture and population density. It was found that although correlation exists, its degree varies depending on the method used to describe image texture. The highest correlation is given by the spatial metrics method. This result suggests that the correlation between texture and population density is not strong enough to predict or forecast residential population. However, image texture does provide a base to refine census-reported population distribution using remote sensing. High-resolution satellite images therefore have the potential to support "smart interpolation" programs to estimate human population distribution in areas where detailed information is not available.
Barrett’s Esophagus Without Esophageal Stricture Does Not Increase the Rate of Failure of Nissen Fundoplication

ObjectiveTo assess whether the presence of Barrett’s esophagus (BE) modifies the results of Nissen fundoplication. Summary Background DataSome authors consider that BE, whether or not there is associated stricture, significantly increases the failure rate of standard antireflux surgery; they recommend using different and more aggressive surgical procedures in all patients with BE. MethodsOne hundred seventy-seven patients with gastroesophageal reflux disease, without esophageal stricture, were included in a retrospective study. Patients were divided into two groups: those with BE (n = 57) and those without BE (n = 120). Nissen fundoplication was performed in all patients by the same surgical team. Clinical, endoscopic, and functional (manometry and 24-hour pH monitoring) results in the two study groups were compared. ResultsAfter a median follow-up of 5 years (range 1–18) in the BE group and 6 years (range 1–18) in the non-BE group, the rate of clinical recurrence was 8% in the BE group and 10% in the non-BE group, with no statistically significant difference. The rate of pH-metric recurrence was the same in both groups (15%). ConclusionsThe presence of BE without esophageal stricture does not increase the rate of failure of Nissen fundoplication.

[CpRu]-catalyzed carbene insertions into epoxides: 1,4-dioxene synthesis through S(N)1-like chemistry with retention of configuration.

Rather than lead to the usual deoxygenation pathway, metal carbenes derived from α-diazo-β-ketoesters undergo three-atom insertions into epoxides using a combination of 1,10-phenanthroline and [CpRu(CH3CN)3][BAr(F)] as the catalyst. Original 1,4-dioxene motifs are obtained as single regio- and stereoisomers. A perfect syn stereochemistry (retention, e.r. up to 97:3) is observed for the ring opening, which behaves as an S(N)1-like transformation.
THE EFFECT OF SLEEP DEPRIVATION ON DEPRESSED PATIENTS

In this paper an account is given of the effect of single‐night sleep deprivation (SD) therapy in 124 depressive patients of different diagnostic groups. Phasic depressives showed a marked improvement after treatment by sleep deprivation. Because these improvements were often of short duration, we repeated the treatments and combined them with thymoleptic drugs. In the group of neurotic depressives the therapeutic effect of sleep deprivation varied; on the whole, however, the improvement was less marked. It is pointed out that the vital symptoms and “critical time” are of importance. Sleep deprivation can be explained as a resynchronization of disturbed circadian rhythms brought about by interrupting these rhythms.
Evaluation of vitamin E and calcium effects on fluoride toxicity-induced fertility impairment

Chronic fluoride (Fl) toxicity is a serious public health problem globally where drinking water contains more than 1 ppm of Fl. Sodium fluoride (NaF) produced male reproductive system toxicity. The aim of the present study was to evaluate the amelioration of Fl toxicity-induced fertility impairment by vitamin E and calcium during the withdrawal period. The study was carried out on 70 adult male albino rats divided into five main groups: group I control; subdivided into group Ia (maintained on standard diet and water ad libitum for 60 days) and group Ib (maintained on standard diet and water ad libitum for 120 days), group II was administered NaF and subdivided into group IIa (administered NaF for 60 day and sacrificed) and group IIb (administered NaF for 60 day then maintained on standard diet and water ad libitum for a further 60 days), and treated groups III, IV, and V were administered NaF. Rats were maintained during withdrawal from NaF, on vitamin E (10 mg kg−1 day−1 for 60 days), calcium (50 mg kg−1 day−1 orally for 60 days), and both vitamin E and calcium, respectively. The duration of NaF administration was 60 days at a dose 20 mg kg−1 day−1 for all treated groups. The following parameters were determined: body and organ weights, sperm motility, sperm morphology, sperm viability, fertility test, and hormone assays: testosterone, in vitro testosterone production, luteinizing hormone, and follicular stimulating hormone. The combined administration of vitamin E and calcium during withdrawal from NaF showed significant improvement from chronic FL-induced toxicity on male reproductive organs.
Evaluation of electronic technology to assess lamb carcass composition.

Accurate price signals are essential for producers of American lamb to ensure production of uniformly lean animals. Development of carcass merit-pricing systems will require the use of objective technology for assessing carcass composition or lean distribution. The objective of this study was to evaluate electronic technologies for accurate determination of lamb carcass composition. Lambs (n = 106) were selected as a representation of U.S. market lambs that transcended geographic location, sex, breed, carcass weight, yield grade, and production system. The independent variables used to predict lamb composition varied with the technology. The electronic technologies tested included realtime ultrasound, optical reflectance probe, bioelectrical impedance analysis, and electromagnetic scanning (TOBEC). All technologies, except realtime ultrasound, were tested on warm (prerigor) carcasses and repeated after a 24-h chill. Longitudinal ultrasonic scans of fat and muscle tissue depth and grading probe fat depths were marginal predictors of proportional carcass yield. The TOBEC measurements often accounted for more variability associated with kilograms of dissected lean and percentage of carcass lean than did carcass weight. Equations from TOBEC measurements were the most accurate predictors of weight and percentage of dissected and fat-free lean. Bioelectrical impedance measurements of resistance and reactance combined with carcass weight were also good predictors of carcass composition. Prediction of carcass lean distribution by measures of TOBEC were the most accurate for prediction of leg lean. The implications of usefulness of these technologies will depend on the commitment of the U. S. sheep industry in development of a lamb price discovery system based on carcass composition.
Hybrid finite element-finite difference method for thermal analysis of blood vessels

A hybrid finite-difference/finite-element technique for the thermal analysis of blood vessels embedded in perfused tissue has been developed and evaluated. This method provides efficient and accurate solutions to the conjugated heat transfer problem of convection by blood coupled to conduction in the tissue. The technique uses a previously developed 3D automatic meshing method for creating a finite element mesh in the tissue surrounding the vessels, coupled iteratively with a 1-D marching finite difference method for the interior of the vessels. This hybrid technique retains the flexibility and ease of automated finiteelement meshing techniques for modelling the complex geometry of blood vessels and irregularly shaped tissues, and speeds the solution time by using a simple finite-difference method to calculate the bulk mean temperatures within all blood vessels. The use of the 1D finite-difference technique in the blood vessels also eliminates the large computer memory requirements needed to accurately solve large vessel network problems when fine FE meshes are used in the interior of vessels. The accuracy of the hybrid technique has been verified against previously verified numerical solutions. In summary, the hybrid technique combines the accuracy and flexibility found in automated finite-element techniques, with the speed and reduction of computational memory requirements associated with the 1D finite-difference technique, something which has not been done before. This method, thus, has the potential to provide accurate, flexible and relatively fast solutions for the thermal analysis of coupled perfusion/blood vessel problems, and large vessel network problems.
Maternal docosahexaenoic acid supplementation during pregnancy and visual evoked potential development in term infants: a double blind, prospective, randomised trial

Aim: To test the hypothesis that maternal docosahexaenoic acid (DHA) supplementation during pregnancy enhances maturation of the visual evoked potential (VEP) in healthy term infants. Methods: One hundred women were supplemented with either fish oil capsules rich in DHA (n = 50) or placebo capsules (n = 50) from week 15 of pregnancy until delivery. Total fatty acids in red blood cells and plasma were measured at weeks 15, 28, and 40 of pregnancy and at delivery in umbilical cord blood. Infant visual pathway development was assessed using VEPs recorded to flash stimuli shortly after birth and to both flash and pattern-reversal stimuli at 50 and 66 weeks post-conceptional age (PCA). Results: Maternal supplementation did not significantly elevate the level of DHA in umbilical cord blood. Moreover, there were no significant differences in any of the VEP measures observed between supplementation groups. However, maturity of the pattern-reversal VEP at 50 and 66 weeks PCA was associated with DHA status of the infants at birth. Infants with higher DHA status, both as a concentration and as a percentage of total fatty acids, showed shorter P100 peak latencies of the pattern-reversal VEP than those with lower DHA status. Conclusions: Maternal DHA supplementation during pregnancy did not enhance VEP maturation in healthy term infants. However, these results show an association between the DHA status of infants at term and early postnatal development of the pattern-reversal VEP, suggesting that DHA status itself may influence maturation of the central visual pathways.
