Background:

Atrial fibrillation (AF) ablation is facilitated by anatomical visualization of the left atrium (LA) and the pulmonary veins (PVs). The purpose of this study was to compare accuracy, radiation exposure, and costs between three‐dimensional atriography (3D‐ATG) and cardiac computed tomography (CCT).
Methods:

Seventy patients with an indication for AF ablation were included. Contrast‐enhanced CCT was performed preoperatively for all patients. In addition, intraoperative 3D‐ATG was performed with contrast medium injection either indirectly into the pulmonary arteries during a breath‐hold (Ind.‐RTA, n = 25) or directly into the LA, during adenosine‐induced asystole (Ad.‐RTA, n = 23), or rapid ventricular pacing (VP‐RTA, n = 22). We evaluated vertical ostial PV diameters and LA volume, time needed to perform, radiation exposure, and procedural cost for each imaging method.
Results:

The correlation coefficient between 3D‐ATG and CCT for the ostial PV diameters was r = 0.83 for Ind.‐RTA, 0.91 for Ad.‐RTA, and 0.88 for the VP‐RTA method (P > 0.05). The volume correlations were r = 0.87 for Ind.‐RTA, 0.82 for Ad.‐RTA, and 0.8 for VP‐RTA (P > 0.05). Time to perform was 13 ± 5 minutes for ATG and 46 ± 9 minutes for CCT (P < 0.05). Effective radiation dose was 2.2 ± 0.2 mSv for ATG and 20.4 ± 7.4 mSv for CCT (P < 0.05). The procedural cost was estimated at 91–95 € for ATG and at 126–151 € for CCT.
Conclusions:

3D‐ATG is an intraprocedural imaging modality that provides anatomical accuracy comparable to that of CCT with significantly lower radiation dose, in less time and at less financial expense (PACE 2011; 34:315–322)

AbstractContinuous ionic dialysance monitoring is a useful clinical tool to determine the dialysis dose in real time in each hemodialysis session. We followed up 49 patients for 16 months. Six patients with a Kt reduction of ≥20% in >3 consecutive hemodialysis sessions were identified. Fistulography demonstrated significant stenosis in all 6 patients. Angioplasty was performed in 5 with an excellent angiographic result and optimal Kt levels were restored. Unexplained and persistent Kt reduction in patients with stable chronic kidney disease under hemodialysis could represent, together with an accurate vascular access examination, a practical and additional indirect method for the early detection of vascular access dysfunction.

Authors: Widni EE , Höllwarth ME , Saxena AK 
Published: November 2010

AbstractAim:  This study analysed nonsexual male genital injuries in boys with regards to aetiology, age, management and outcome.Methods:  Patients were identified from the hospital database (between 1999 and 2009) were analysed retrospectively.Results:  Seventy‐four patients (2–17 years) were identified which included 24 toddlers and small children (2–5 years), 36 school age children (6–12 years) and 14 adolescents (13–17 years). Traumas were related to falls (n = 14), kicks (n = 11), sport (n = 10), toilet seats (n = 9), motor vehicles (n = 8), bicycle (n = 4), outdoor activities (n = 4) and others causes (n = 14). The leading cause of injuries in (i) toddler and small children was related to toilet seat (n = 7) and falls (n = 7), (ii) school age children to sport (n = 8), kicks (n = 7) and falls (n = 6), and (iii) adolescents to motorcycle accidents (n = 5). There were 45 scrotal and 29 penile injuries ranging from lacerations to contusions. Sixty‐eight patients required hospital stay (0.5–36 days, Σ = 2.4 days). Follow‐up examinations were uneventful, except for one minor wound infection.Conclusion:  Nonsexual traumas to the male external genitalia occur mostly in 6‐ to 12‐year‐old boys, with sport accidents, kicks and falls being the major causes. Scrotal and penile lacerations and testicular contusions are the most common injuries. Complications after injuries to the male genitals in children are rare.

Published: November 2010

ABSTRACTPurpose: Early detection of healing complications after placement of dental implants is a pressing but elusive goal. This paper proposes a non‐invasive diagnostic tool for monitoring healing‐ and peri‐implant disease specific genes, complementary to clinical evaluations.Material and Methods: Eighteen partially edentulous patients were recruited to this pilot study. Three Brånemark TiUnite® implants/patient (Nobel Biocare) were placed in a one‐stage procedure. Abutments with smooth or rough (TiUnite®) surface were placed. The test group (n = 9) received fixed bridges (immediate loading), whereas the control group (n = 9) implants were loaded 3 months after surgery. In addition to clinical measurements, crevicular fluid was collected using paper strips at the implant abutments 2, 14, 28, and 90 days postoperative. mRNA was extracted, purified, and converted to cDNA. Quantitative PCR assays for IL‐1β, TNF‐α, Osteocalcin (OC), Alkaline Phosphatase (ALP), Cathepsin K, Tartrate Resistant Acid Phosphatase, and 18S ribosomal RNA were designed and validated. Relative gene expression levels were calculated.Results: One implant was lost in the control group and three in the test group. In one test patient, one implant showed lowered stability after 2 to 4 weeks and was unloaded. Later implant stability improved which allowed for loading after 3 to 4 months. TNF‐α and ALP most commonly showed correlation with clinical parameters followed by IL‐1β and OC. The strongest correlation was found for TNF‐α with clinical complications at 2 and 14 days (p = .01/r = −048, and p = .0004/r = −0.56, respectively; test and control groups together). In some cases, gene expression predicted clinical complications (TNF‐α, ALP, CK).Conclusion: This study is based on samples from few individuals; still, some genes showed correlation with clinical findings. Further studies are needed to refine and optimize the sampling process, to find the appropriate panel, and to validate gene expression for monitoring implant healing.
Decreasing retinol and α‐tocopherol concentrations in human milk and infant formula using varied bottle systems

Published: November 2010

AbstractExpressing human milk has become a more common alternative for mothers, as the average work demand has increased. As more mothers must work, bottle feeding trends are increasingly common. The handling and storage of human milk introduce the risk of degradation to expressed human milk and infant formula. In following a 20‐minute simulated feeding, Vitamin C has been found to degrade. Vitamin C acts as an anti‐oxidant and is responsible for shielding other nutrients from oxidation, such as retinol and alpha‐tocopherol. By analyzing a 20‐minute simulated feeding, retinol and alpha‐tocopherol each displayed decreases over time significantly different than that of the Control, which was milk not exposed to bottle feeding. In human milk, retinol showed as high as a 9.5% decrease compared to the Control. Similar trends were seen with the infant formula samples. The correlation between degradation and bottle feeding systems was dependent upon the formation of bubbles in the milk as the milk was removed from the bottle. The analysis indicated a decrease of up to 12%, as seen in retinol, and 35%, as seen in alpha‐tocopherol. These decreases in retinol and alpha‐tocopherol should be considered when using a bottle feeding system to deliver either human milk or formula to an infant. More research is necessary to determine the effect of this decrease on the nutritional status of infants, particularly premature infants, who are at higher risk for nutrient deficiencies.
Deepwater Disaster: How the Oil Spill Estimates got it Wrong
Authors: MacDonald Ian 
Published: November 2010

Abstract
“There is no crude emanating from that riser.” Then the official estimate was 1000 barrels a day, then 5000. The true figure was 58 000 barrels of oil a day leaking into the Gulf of Mexico. Why did the authorities so consistently underestimate the flow from the Deepwater disaster, and what damage did those underestimates do?Ian MacDonald reveals the smoking gun behind BP's erroneous statistics.

Pictish Symbol Stones: Religious Imagery, Heraldic Arms or a Language?
Authors: Lee Rob , Jonathan Philip , Ziman Pauline 
Published: November 2010

AbstractThe Pictish Symbol Stones are a collection of finely carved stones dating from ca. 300 AD to 843 AD whose meaning has been lost in time. Despite attracting linguists and historians alike, as a collection they have been just too small to surrender their secrets. Now, however, Rob Lee, Philip Jonathan and Pauline Ziman have used a technique based on comparative entropy to unwrap some of the mystery of the stones.

Statistics and Animals in Biomedical Research
Authors: Festing Michael 
Published: November 2010

Abstract
A UK government-sponsored review1 has found that out of 271 randomly chosen papers reporting experiments on laboratory animals only 59% stated the objective of the study and the number of animals used. Most did not use randomisation or blinding, and only 70% of the publications that used statistical methods gave their methods and a measure of error. Michael Festing, one of the authors of the review, wants better statistics in animal experiments.

doi: 10.1111/j.1741‐2358.2010.00438.xEvaluation of experimental cleanser solution of Ricinus communis: effect on soft denture liner propertiesObjective:  This study evaluated colour stability, hardness and roughness of soft denture liners after immersion in various cleansers.Materials and methods:  Thirty specimens (14 mm × 4 mm) of Elite Soft Relining (ES) and Mucopren Soft (MS) were randomly immersed in distilled water at 37°C, sodium hypochlorite 1%, and an experimental Ricinus communis solution (RC) for 7, 15 and 183 continuous days.Results:  anova (p < 0.05) and Tukey’s test indicated that after T7 (μ =8.79 ± 7.36); T15 (μ = 4.23 ± 2.62) and T183 (μ = 8.78 ± 3.16), MS presented a higher increase in hardness than ES. After T7, MS underwent an increase in roughness (μ = 0.09 ± 0.80); ES underwent a decrease (μ = −0.08 ± 0.16). RC caused the smallest variation in roughness. After T15, both materials presented an increase in roughness. After T183, ES (μ = −0.30 ± 0.48) presented a higher roughness variation than MS (μ = −0.07 ± 0.32). Hypochlorite caused an increase in roughness (μ = 0.02 ± 0.19).Conclusion:  After all periods ES presented higher colour alteration than MS; highest colour alteration was caused by hypochlorite. Both materials were more stable after immersion in RC.

doi: 10.1111/j.1741‐2358.2010.00442.xA conventional microwave oven for denture cleaning: a critical reviewIntroduction:  Denture cleaning should be quick and easy to perform, especially in long‐term care facilities. The lack of proper oral hygiene can put older adults at higher risk from opportunistic oral infections, particularly fungal. As an alternative to regular brushing, the use of a microwave oven has been suggested for cleaning and disinfecting dentures.Objectives:  To synthesise and discuss the advantages and disadvantages of the use of a conventional microwave oven for cleaning and disinfecting complete dentures.Methods:  A brief literature search focused on papers dealing with microwave therapy for denture cleaning through PubMed Central, Cochrane Database of Systematic Reviews, Google Scholar, Ovid MEDLINE(R) In‐Process, and Scifinder Scholar.Results:  One hundred and sixty‐seven manuscripts published in English with full text were found, and 28 were accepted and discussed in the light of the advantages and disadvantages of the use of conventional microwave oven for cleaning and disinfecting complete dentures.Conclusions:  There was no standardisation for microwave use for denture cleaning. Manual cleaning still seemed to be the optimal method for controlling fungal infection and denture stomatitis. However, such a daily routine appeared to be underused, particularly in long‐term care facilities.

Oral hygiene and periodontal disease in Victorian nursing homesObjective:  To investigate oral hygiene and periodontal disease in residents of Victoria nursing homes.Background:  The Australian population is ageing with a growing proportion of elderly Australians living in nursing homes. With declining edentulism rates, periodontal disease is becoming more prevalent in this population.Materials and methods:  A total of 275 dentate residents from 31 Victorian nursing homes had a questionnaire and clinical examination using the Visual Plaque Index and a modified Community Periodontal Index.Results:  Self‐reported oral hygiene habits of residents were poor, with less than one‐third of residents cleaning their teeth twice daily or more. Periodontal health was found to be extremely poor, and the prevalence of 4 mm+ periodontal pockets was 35.6%, with 10.2% having 6 mm+ pockets. Logistic regression found that age, gender, number of teeth present and oral hygiene were all strongly associated with the prevalence of 4 mm+ periodontal pockets.Conclusion:  Poor oral hygiene and the presence of significant plaque and calculus were common findings in this study. Periodontal diseases are a significant problem for residents in nursing homes. Addressing this health issue will require improved training for carers and better access to appropriate dental services.

doi: 10.1111/j.1741‐2358.2010.436.xClinical evaluation of three denture cushion adhesives by complete denture wearersObjective:  The aim of this study was the clinical evaluation of three denture cushion adhesives and whether the results were correlated to Kapur Index for denture‐supporting tissues.Background:  Various types of denture adhesives are used among denture patients. However, information on the clinical behaviour of denture cushions is limited.Materials and methods:  Thirty edentulous patients had their denture‐supporting tissues scored by Kapur Index and their old dentures replaced. They received three brands of denture cushion adhesives (Fittydent®, Protefix® and Seabond®) and were instructed to use them in a sequence according to the group they were randomly assigned to. Each brand of adhesive was used for 48 h on the lower denture according to the manufacturer’s suggestions. After each brand was used, participants spent 24 h without applying any sort of adhesive. Finally, a questionnaire evaluating and comparing the performance of each brand was filled out.Results:  Denture adhesives generally improved patient satisfaction and masticatory ability, especially in participants with poor Kapur Index and those who reported a poor retention of their old dentures.Conclusion:  Fittydent® was the most preferred adhesive, showing the best retention and the longest duration of its effect, but also reported as difficult to remove from the denture‐bearing area.
Rice OsRAD21‐2 is Expressed in Actively Dividing Tissues and its Ectopic Expression in Yeast Results in Aberrant Cell Division and Growth

Published: November 2010

Abstract Rad21 and its meiotic counterpart Rec8, the key components of the cohesin complex, are essential for sister chromatid cohesion and chromosome segregation in mitosis and meiosis, respectively. In contrast to yeast and vertebrates, which have only two RAD21/REC8 genes, the rice genome encodes four Rad21/Rec8 proteins. Here, we report on the cloning and characterization of OsRAD21‐2 from rice (Oryza sativa L.). Phylogenetic analysis of the full‐length amino acids showed that OsRad21‐2 was grouped into the plant‐specific Rad21 subfamily. Semi‐quantitative reverse transcription‐polymerase chain reaction revealed OsRAD21‐2 preferentially expressed in premeiotic flowers. Further RNA in situ hybridization analysis and promoter::β‐glucuronidase staining indicated that OsRAD21‐2 was mainly expressed in actively dividing tissues including premeiotic stamen, stem intercalary meristem, leaf meristem, and root pericycle. Ectopic expression of OsRAD21‐2 in fission yeast resulted in cell growth delay and morphological abnormality. Flow cytometric analysis revealed that the OsRAD21‐2‐expressed cells were arrested in G2 phase. Our results suggest that OsRad21‐2 functions in regulation of cell division and growth.

Abstract Mungbean (Vigna radiata (L.) Wilczek) is a unique species in its ability to fix atmospheric nitrogen, with early maturity, and relatively good drought resistance. We used 454 sequencing technology for transcriptome sequencing. A total of 150 159 and 142 993 reads produced 5 254 and 6 374 large contigs (≥500 bp) with an average length of 833 and 853 for Sunhwa and Jangan, respectively. Functional annotation to known sequences yielded 41.34% and 41.74% unigenes for Jangan and Sunhwa. A higher number of simple sequence repeat (SSR) motifs was identified in Jangan (1 630) compared with that of Sunhwa (1 334). A similar SSR distribution pattern was observed in both varieties. A total of 8 249 single nucleotide polymorphisms (SNPs) and indels with 2 098 high‐confidence candidates were identified in the two mungbean varieties. The average distance between individual SNPs was ∼860 bp. Our report demonstrates the utility of transcriptomic data for implementing a functional annotation and development of genetic markers. We also provide large resource sequence data for mungbean improvement programs.
Seasonal distribution and prevalence of dung beetles (Coleoptera: Scarabaeidae) in Kurukshetra, Northern India
Authors: KAKKAR Nidhi 
Published: November 2010

AbstractA total of 8306 individuals as 29 species from 3 subfamilies (Hybosorinae, Aphodiinae, Scarabaeinae) were trapped by pitfall bait trapping. The maximum number of species of Scarabaeinae (68.97%) and number of individuals of Aphodiinae (56.84%) take part in the formation of a community. The number of species, number of individuals, diversity and dominance changes throughout the season. Seasonal prevalence of 82.76% of species and 50.81% of individuals was found in June. Aphodius campestris was found to be more attracted to the pitfall bait traps. The beetle community found in May shows the maximum Shannon's Diversity Index (2.46) but Margalef's Diversity Index was highest in August (3.06). Environmental factors play an important role in the occurrence and abundance of dung beetles. In the present study non‐significant but positive correlations between temperature and species richness, abundance and diversity were found. Percent relative humidity showed a positive correlation with abundance only, and negative correlations with species richness and diversity.
