Authors: Amaral Cristine da Silva Furtado , Luiz Ronir Raggio , Leão Anna Thereza Thomé 
Published: June 2008

Background: The aim of this study was to evaluate the relationship between alcohol dependence and periodontal disease.Methods: A cross‐sectional study of 49 alcoholic and 49 non‐alcoholic men was conducted at Philippe Pinel Institute, Rio de Janeiro, Brazil. Subjects were screened for alcohol dependence using the CAGE (cut‐down, annoyed, guilty, eye‐opener) questionnaire and the criteria of the International Statistical Classification of Diseases, 10th Revision. Sociodemographic data and periodontal clinical parameters, such as visible plaque, bleeding on probing, probing depth (PD), and clinical attachment level (CAL), were collected. Groups were controlled for smoking. Intergroup comparisons of sociodemographic data and mean percentage of clinical parameters were analyzed by the χ2 and Mann‐Whitney tests. The independent effect of alcohol dependence on CAL and PD was assessed by multiple linear regression analysis, adjusting for the effects of plaque, age, income, education, and living conditions.Results: A significant linear relationship was found between alcohol dependence and mean CAL (P ≤0.013) and mean PD (P ≤0.001).Conclusion: Alcohol dependence may be associated with an increased severity of CAL and PD.

Published: June 2008

Background: The purpose of this study was to compare and evaluate bone and soft tissue levels between immediately placed, immediately restored implants positioned in the esthetic anterior region with different interimplant distances (IID).Methods: Forty‐nine patients requiring multiple implant restorations in the anterior regions received 152 implants, which were restored immediately. Periapical radiographs and digital images of 99 interimplant sites were taken at the regular follow‐up examinations at 0, 6, 12, and 24 months after surgery. They were digitally recorded and analyzed. The presence of the interproximal papilla was assessed and compared to the distances between the bone crest and the contact point between the natural teeth and the restoration crowns.Results: Implants with an IID <2 mm seemed to lose less bone laterally. When the IID was <2 mm, vertical crestal bone loss was significantly greater than in the group with IID >4 mm. The percentage of the interproximal papilla presence decreased when the distance between the bone crest and the contact point between the two restoration crowns was >6 mm and when two implants were placed at a distance ≥4 mm.Conclusions: To guarantee a better esthetic result in immediately placed, immediately restored implants, the contact point between the two prosthetic crowns should be placed at 3 to 4 mm, and never >6 mm, from the bone peak. Two adjacent implants should be placed at a distance >2 and <4 mm.

Published: June 2008

Background: The incidence of dry mouth and its public health impact are increasing as the result of a progressively larger, medicated older population and because chronic diseases, like periodontitis, are prevalent pathologies among elderly patients. Periodontitis and continuous remodeling and rebuilding alveolar processes greatly affect the margin of the alveolar bone, and there is evidence indicating the role of submandibular glands in the regulation of immune/inflammatory reactions. The purpose of this study was to assess the effect of submandibular–sublingual complex ablation (Sx) on alveolar bone loss in rats submitted or not to ligature‐induced experimental periodontal disease (EP).Methods: Wistar male rats were submitted to Sx or sham operations (day 0). Two weeks later, unilateral EP was induced on the right mandibular first molars for 7 days with the contralateral side serving as control. Bone loss at the level of the dental pieces was estimated by bone histomorphometry on mesio‐distally oriented sections of the molars and by the determination on lingual and vestibular mandibular surfaces of the distances from the cemento‐enamel junction to the alveolar crest.Results: Sx and EP significantly increased lingual and vestibular alveolar bone loss. Molars with EP exhibited greater lingual loss in Sx animals compared to those with the sham operation. EP induced similar interradicular bone loss in sham and Sx rats.Conclusion: Sx has a deleterious effect on the periodontal tissues, particularly marginal alveolar bone, indicating the importance of the submandibular/sublingual glands in maintaining healthy periodontal conditions.
Preparing a Fractured Carbonate Field for Steam Injection

Published: June 2008

Abstract
The subject field is a fractured carbonate reservoir located in the Ghaba Salt Basin in Oman containing heavy, viscous oil. The field was discovered in 1972 and has been producing since 1976 through a process of mainly fracture depletion and natural water-influx. Without the application of an EOR technique the recovery will be low as the processes that displace oil from the matrix reservoir rock are adversely affected by the rock and fluid properties, particularly the high oil viscosity. Following the success of the steam-assisted GOGD test in an analogous nearby field, the field is being screened for feasibility of this thermal recovery process. In the steam-assisted GOGD process the fracture network plays a dual role: as distribution system of crestally injected steam to heat up the oil in the matrix and as offtake point deeper down in the column where the oil collects in the fracture oil-rim, after having drained predominantly through the matrix. Critical data on the fracture network and thermal PVT properties are collected and integrated in dynamic models to assess the oil drainage rate under steam injection.
In modeling the SA-GOGD process, care needs to be taken to correctly represent the effect of unevenly heated matrix blocks on the oil viscosity and hence drainage rates. Oil close to the steam filled fractures will heat up more quickly than in the center of the matrix blocks and the former will start to drain faster than the latter. Ignoring this effect and using viscosity values based on averaged temperatures and established viscosity-temperature relationship, as is usually done in dual permeability simulation, will underestimate the SA-GOGD drainage rates. This underestimation will increase with a larger difference between the cold and hot oil viscosity and is also more relevant to early times (economics). A new method has been developed to conserve the 1D-drainage rate of unevenly heated matrix blocks based on an effective or "pseudo" viscosity correlated with gridblock-averaged temperature.
Vascular abnormalities and low-grade chronic inflammation in women with polycystic ovary syndrome: Relationships with insulin resistance, obesity and hyperandrogenemia

Published: June 2008

Abstract
Polycystic ovary syndrome (PCOS) is possibly the most common endocrinopathy of reproductive age, characterized by hyperandrogenism and oligomenorrhea. Additionally, approximately one-third to one-half of all women and adolescent girls with PCOS tend to fulfill many of the metabolic syndrome criteria, and many view PCOS as a premetabolic syndrome condition, predisposing to a high risk for cardiovascular disease. Endothelial dysfunction, impaired arterial structure, or proinflammatory markers are early features of atherosclerosis, and can be used as surrogate indicators of future coronary artery disease in women with PCOS. However, as the latest studies show, these symptoms are the result of deleterious effects that cardiovascular risk factors, in particular insulin resistance and obesity, produce on the vascular wall, rather than to the presence of PCOS per se. The relationship between hyperandrogenemia and the risk of cardiovascular disease is controversial and needs to be clarified. Further research is warranted to understand the pathogenesis of cardiovascular disease in PCOS, and to identify subtypes of PCOS in which the presence of cardiovascular risk factors may result in increased cardiovascular events, leading to high morbidity or mortality rates caused by cardiovascular disease.
Dielectric relaxation behaviour of liquid crystals with opposite orientation of -COO ester group in molecular core
Authors: Rutkowska J. , Perkowski P. , Piecek W. , Raszewski Z. , Kędzierski J. 
Published: June 2008

AbstractDielectric measurements were performed for two smectogens, being structurally analogous with the opposite space orientation of the-COO ester group in the molecular core, using a HP4192A impedance analyser. Gold coated electrode cells of different thicknesses were used. Temperature dependences of the relaxation frequency fR and the inverse of the dielectric strength Δε′┴ −1 obtained by fitting experimental values of perpendicular components, i.e., the real ε′┴ and the imaginary ε″┴ parts of the complex dielectric permittivity to the Cole-Cole equation as well as the investigation of modification of relaxation processes under bias were determined for the SmC*, SmA*, and N* phases of studied compounds. One can conclude, on the basis of the above results, that dielectric relaxation processes observed by us in the studied compounds are similar to those of the soft and Goldstone mode typically observed by others in the SmC*, SmA*, and N* phases. It is concluded from acomparison of their properties with other related compounds that the link between the biphenyl moiety and-COO ester group is closely related to the stability of smectic phases.
Adiponectin attenuates endothelial dysfunction induced by oxidised low-density lipoproteins
Authors: Plant Stuart , Shand Brett , Elder Peter , Scott Russell 
Published: June 2008

We investigated whether the adipocytokine, adiponectin, protected the endothelium against damage induced by oxidised low-density lipoprotein cholesterol (oxLDL). Human umbilical vein endothelial cells were cultured with either 200 or 350 μg/ml oxLDL, with or without adiponectin purified from human serum (12 μg/ml). Cellular oxidative status was assessed by measuring reactive oxygen species (ROS), peroxynitrite and glutathione (GSH) levels, while cell function was evaluated by measuring nitric oxide (NO) levels and immunohistochemical examination of proteins in the adherens cell junction. At a concentration of 200 μg/ml, oxLDL induced a small increase in ROS and peroxynitrite levels, a two-fold increase in GSH levels and no changes in NO levels or localisation of proteins in the adherens junction. However, 350 μg/ml of oxLDL induced a marked increase in ROS and peroxynitrite levels, a four-fold reduction in GSH levels and a significant decrease in NO levels and disruption of the adherens junctions. Addition of adiponectin to the cultures resulted in maintenance of normal ROS, peroxynitrite and GSH levels, with no change in either NO levels or protein localisation in the adherens junction. This study demonstrates that adiponectin protects against endothelial dysfunction and cellular disruption induced by oxLDL, with this effect being due, in part, to maintenance of intracellular GSH levels.

Published: June 2008

The purpose of this study was to assess the effect of rosiglitazone on bioavailable, free and total testosterone levels in hypogonadal men with type 2 diabetes. Sixteen type 2 diabetic men with hypogonadism were studied before and after administration of rosiglitazone (8 mg/day) for six months, with assessments performed every two months on two consecutive days. We measured testosterone and sex hormone binding globulin (SHBG), visceral adiposity, high-sensitivity CRP (hs-CRP), lipids, microalbuminuria and blood pressure. There was a significant increase in free (p=0.01), bioavailable (p=0.007) and total testosterone (p=0.002), as well as SHBG (p=0.03) levels, with rosiglitazone treatment. Waist circumference and waist/hip ratio decreased with the improvement in insulin sensitivity and glycaemic control (p=0.01). There was also a significant reduction in hs-CRP (p=0.02) and urinary albumin excretion. No significant effect on blood pressure or the ratio of low-density lipoprotein cholesterol to high-density lipoprotein cholesterol (LDL to HDL) was seen. In conclusion, the insulin-sensitiser rosiglitazone increases bioavailable, free and total testosterone and SHBG levels in hypogonadal men with type 2 diabetes.

Published: June 2008

AbstractInterstitial deletions of the proximal long arm of chromosome 3 are very rare and a defined clinical phenotype is not established yet. We report on the clinical, cytogenetic and molecular findings of a 20‐month‐old Hispanic male with a 2.5 Mb de novo deletion on q13.11q13.12. Up to now, this is the smallest deletion reported among patients with the proximal 3q microdeletion syndrome. The patient has distinct facial features including brachycephaly, broad and prominent forehead, flat nasal bridge, prominent ears, anteverted nose, tetralogy of Fallot, bilateral cryptorchidism, and peripheral skeletal abnormalities. To further delineate the proximal 3q deletion syndrome, the phenotype of our patient was compared with 10 other patients previously described. We found that ALCAM and CBLB are the only genes deleted in our patient and based on previously published data, we propose that the CBLB gene is responsible for the craniofacial phenotype in patients with deletions of proximal 3q region. © 2008 Wiley‐Liss, Inc.

Published: June 2008

AbstractEarly adversity predicts anxiety and depression but variation in response to adversity is not understood. We investigated whether association between early adversity and emotional symptoms in young children differs according to variation of the COMT gene. The main outcome measure was the emotionality subscale of the Strengths and Difficulties Questionnaire (SDQ) completed by mothers for 8,431 children aged 6–7 years old in the Avon Longitudinal Study of Parents and Children. Adversity measures included exposure to maternal postpartum depressive symptoms and adverse life events for children. DNA from the children was genotyped for five COMT polymorphisms including the COMT Val158Met locus. Maternal depression increased the odds of high emotionality in the children, (OR 1.99, 95% CI 1.73–2.29, P < 0.001) as did life events score, (OR 1.21 for each s.d. increase in life event score, 95% CI 1.15–1.27, P < 0.001). There was no main effect of Val158Met genotype on emotional symptoms (OR for effect of each copy of the methionine allele was 1.04, 95% CI 0.97–1.10, P = 0.284). The relationship between adversity and emotional symptoms did not vary by genotype (G × E for maternal depression χ2 = 3.17, P = 0.205; G × E for life events χ2 = 1.69, P = 0.430). There was no main effect of COMT haplotype, nor was there an interaction with adversity. Early adversity predicts emotional symptoms in children aged 6–7 years. Although some studies indicate a role for COMT in emotionality, anxiety, and depression in adults, no direct effect or interaction of COMT genotype was observed in this large sample of young children. © 2008 Wiley‐Liss, Inc.
The public's probabilistic numeracy: How tasks, education and exposure to games of chance shape it
Authors: Hertwig Ralph , Andrea Zangerl Monika , Biedert Esther , Margraf Jürgen 
Published: June 2008

AbstractAs we navigate a world full of uncertainties and risks, dominated by statistics, we need to be able to think statistically. Very few studies investigating people's ability to understand simple concepts and rules from probability theory have drawn representative samples from the public. For this reason we investigated a representative sample of 1000 Swiss citizens, using six probabilistic problems. Most reasoned appropriately in problems representing pure applications of probability theory, but failed to do so in approximations of real‐world scenarios – a disparity we replicated in a sample of first‐year psychology students. Additionally, education is associated with probabilistic numeracy in the former but not the latter type of problems. We discuss possible reasons for these task disparities and suggest that gaining a comprehensive picture of citizens' probabilistic competence and its determinants requires using both types of tasks.

The IRBIT domain adds new functions to the AHCY family
Authors: Devogelaere Benoit , Sammels Eva , De Smedt Humbert 
Published: June 2008

AbstractDuring the past few years, the IRBIT domain has emerged as an important add‐on of S‐adenosyl‐L‐homocystein hydrolase (AHCY), thereby creating the new family of AHCY‐like proteins. In this review, we discuss the currently available data on this new family of proteins. We describe the IRBIT domain as a unique part of these proteins and give an overview of its regulation via (de)phosphorylation and proteolysis. The second part of this review is focused on the potential functions of the AHCY‐like proteins. We propose that the IRBIT domain serves as an anchor for targeting AHCY‐like proteins towards cytoplasmic targets. This leads to regulation of (i) intracellular Ca2+via the inositol 1,4,5‐trisphosphate receptor (IP3R), (ii) intracellular pH via the Na+/HCO3−cotransporters (NBCs); whereas inactivation of the IRBIT domain induces (iii) nuclear translocation and regulation of AHCY activity. Dysfunction of AHCY‐like proteins will disturb these three important functions, with various biological implications. BioEssays 30:642–652, 2008. © 2008 Wiley Periodicals, Inc.
