A new pan-nitinol occluder for transcatheter closure of ventricular septal defects in a canine model.

BACKGROUND The Amplatzer ventricular septal defect (VSD) occluder has a fixed stainless steel pin bottom protruding out of the surface at the center of the discs on both sides. Theoretically, this protruding bottom may interfere with epithelialization or, in some cases, cause thrombosis. OBJECTIVE To evaluate a new type of pan-nitinol VSD occluder without the protruding stainless steel pin bottom on both sides in a canine VSD model designed to ensure safety, effectiveness, and feasibility. METHODS AND RESULTS VSDs were successfully created by transseptal ventricular septal puncture with a Brockenbrough needle and dilation with an 8-mm-diameter balloon via the right jugular vein in 9 out of 12 canines. The new type VSD occluder was successfully implanted in 8 of the 9 modeled canines. No procedure- or device-related complication was observed. Transthoracic echocardiography and MRI 2 months after device implantations showed that there was no device dislocation or heart valve dysfunction in 6 of the 8 tested canines. In addition, gross and pathological examinations 3-6 months after implantation showed no corrosion of the devices or serious inflammatory reactions in the modeled animals. Complete endothelialization was seen over the surface of the discs. CONCLUSIONS The new pan-nitinol VSD device can be successfully implanted in a canine VSD model via a transcatheter approach featuring high success rate, low risk of procedure-related complications, and sound biocompatibility. The result suggests that this new VSD occluder could be used safely in future clinical trials for further test.
THE IMPACT OF GIVING FEEDBACK ON THE STUDENTS ’ WRITING OF TENTH GRADE AT SMKN 1 NGASEM IN THE ACADEMIC YEAR 2016-2017

Writing is as important as other skills such as listening, speaking, and reading. It needs more special attention since writing is productive skill which doesn’t come naturally or automatically, but through much effort, training, instruction, practice and need continuous feedback. This study intends to investigate the types and techniques of written feedback which are used in teaching writing and to find out whether there is an impact of giving feedback to the students in students writing or not. In accordance with the aims above, an experiment-quantitative was implemented. The subjects of this research were the tenth grade students at SMKN 1 Ngasem who got the activity of getting feedback in teaching writing recount text. Two classes that consist of 70 students had been chosen. The data was gathered using three instruments; pre-test, treatment and post-test . The study found that there was significant result between experiment and control class. The class that given treatments both orally and written feedback has higher score than control class. It proof by the result of maximum score in experiment and control class. According to the finding, it can be identified that the students can receive the researcher feedback after pre-test and applied it to their post-test. Due to these findings, the writer gives recommendation to the students that they have to accustom their self to read the teacher written feedback and as soon as they revise the writing project after the teacher gave them feedback orally or written. The teacher should the researcher suggests the teacher to make a deal or agreement in the class. So the students will more understand about the feedback, it can make time shorter and to minimalize the timing also.
Acute effects of ultraviolet‐B irradiation on the corneal surface of the pigmented rabbit studied by quantitative scanning electron microscopy

Abstract. The eyes of female pigmented rabbits were exposed to a single dose of UV‐B (300 + 9 nm, 0.05 J/cm2 total dose) between 13.30 and 15.00 h. The average irradiance was 225 + 36 μW/cm2 delivered over 191 to 264 s. At various time periods thereafter (24, 48, 72 and 96 h post‐irradiation), the animals were euthanized by pentobarbital overdose and the eyes fixed with 2% glutaraldehyde in 80 mM cacodylate buffer (pH 7.4, total osmolarity of 330–340 mOsm/L). Corneal quadrants were examined by high resolution scanning electron microscopy at 100 × and 500 × at‐stage magnification at central, mid‐peripheral and peripheral sites. The micographs from the central cornea were subjected to a quantitative analysis using a computer based digitization system. A peak effect was observed at 48 h at which cellular exfoliation was noted at the corneal apex. In the region immediately adjacent to the exfoliating cells, the number of light and dark electron reflex cells decreased to 48 h while the numbers of medium‐reflex cells decreased after 48 h. The relative surface area of all cells was also decreased at 48 h compared to unirradiated controls. Significant recovery was observed by 96 h. Mid‐peripheral and peripheral sites were largely unaffected by this just supra‐threshold irradiation.
Protective Effect of a Polyherbal Traditional Formula Consisting of Rosa damascena Mill., Glycyrrhiza glabra L. And Nardostachys jatamansi DC., Against Ethanol-induced Gastric Ulcer

“VARD” formula consisting of Rosa damascena Mill. (Rosaceae) petals, and rhizomes of Glycyrrhiza glabra L. (Papilionaceae) and Nardostachys jatamansi DC. (Valerianaceae), has been proposed for gastric ulcer in Iranian traditional medicine. We investigated the antiulcer activity of each plant separately and in combination. The biochemical and molecular functions of extracts were also evaluated. Each plant hydroalcoholic extract was standardized via determination of total phenolic and flavonoid contents, also via some phenolic compounds determination and specially glycyrrhizic acid in G. glabra by using HPLC. Rats received orally extracts of the plants (20, 40 and 80 mg/Kg) and “VARD” (45 mg/Kg) 1 h before ethanol administration. Two h after receiving ethanol, animals were sacrificed; the stomach was removed for macroscopic and microscopic assessment. Also heme-oxygenase-1, glutathione, and catalase were measured in the gastric tissue of the rats pretreated by “VARD” and dose of 20 mg/Kg of extracts. Among three extracts, R. damascena and G. glabra contained more total phenolic and flavonoid content respectively. Gallic acid was prominent compound in R. damascena. The extracts of R. damascena, G. glabra, and N. jatamansi significantly decreased ulcer index. ED50 values were 8.2, 31.86 and 25.08 mg/Kg respectively. “VARD” significantly decreased ulcer index compared to 20 mg/Kg of G. glabra (p < 0.0001) and N. jatamansi (p < 0.001). Pretreatment with “VARD” and each plant extracts (20 mg/Kg) increased glutathione, catalse and heme-oxygenase-1 significantly (p < 0.05) in comparison with control group. Our findings indicate that “VARD” partly via antioxidant activity can be considered as an effective antiulcer formula.
Training and evaluation of a knowledge-based model for automated treatment planning of multiple brain metastases

Aim: Volumetric modulated arc therapy (VMAT) has been utilized to plan and treat multiple cranial metastases using a single isocenter due to its ability to provide steep dose gradients around targets as well as low doses to critical structures. VMAT treatment is delivered in a much shorter time compared to using a single isocenter for the treatment of each lesion. However, there is a need to develop methods to reduce the treatment planning time for these cases while also standardizing the plan quality. In this work we demonstrate the use of RapidPlan, which is knowledge-based treatment (KBP) planning software to plan multiple cranial SRS cases. Methods: The 66 patient plans with 125 lesions (range 1-4, median 1) were used to train a model. In addition, the model was validated using 10 cases that were previously treated and chosen randomly. The clinical plans were compared to plans generated by RapidPlan for target coverage and critical organ dose. Results: Coverage to the target volume, gradient index, conformity index and minimum dose to the target showed no significant difference between the original clinical plan vs. the plan generated by KBP. A comparison of doses to the critical organs namely the brainstem, brain, chiasm, eyes, optic nerves and lenses showed no significant difference. Target dose homogeneity was slightly better with the clinical plan, however this difference was also statistically
Dementia and Mental Retardation Markers on the Rey 15-Item Visual Memory Test

This study examined the qualitative errors of repetitions and confabulations on the Rey 15-item Visual Memory Test among 500 psychiatric patients who were divided into groups with (1) low IQ scores, (2) a diagnosis of dementia, and (3) other psychiatric diagnoses. These groups were compared on the presence of confabulated figures and repetitions on the Rey. The low IQ patients had the highest rate for both confabulations (48.2%) and repetitions (43.6%). Demented patients had the next highest rate of confabulations (39.8%) and repetitions (39.8%). The general psychiatric patients had the lowest rates on confabulations (16.2%) and repetitions (26.8%). Chi squared analysis showed that both confabulations and repetitions significantly differentiated these patients of low IQ and demented patients from general psychiatric patients. These results suggest that clinicians who use the Rey 15-item Visual Memory Test and find either confabulated or repeated figures should further explore the possibility that the patient might have low intellectual functioning or dementia.
Motor Memory Consolidation in Sleep Shapes More Effective Neuronal Representations

Learning a motor skill involves a latent process of consolidation that develops after training to enhance the skill in the absence of any practice and crucially depends on sleep. Here, we show that this latent consolidation during sleep changes the brain representation of the motor skill by reducing overall the neocortical contributions to the representation. Functional magnetic resonance brain imaging was performed during initial training and 48 h later, at retesting, on a sequential finger movement task with training followed by either a night of regular sleep or sleep deprivation. An additional night of sleep for all subjects served to rule out unspecific effects of sleep loss at retrieval testing. Posttraining sleep, but not sleep deprivation, led to improved motor skill performance at retrieval. This sleep-dependent improvement was linked to greatly reduced brain activation in prefrontal, premotor, and primary motor cortical areas, along with a stronger involvement of left parietal cortical regions. Our findings indicate that storing a motor skill during sleep reorganizes its brain representation toward enhanced efficacy.
Resource implications of expanding the use of donation after circulatory determination of death in liver transplantation

In the United Kingdom, liver transplantation using donation after circulatory determination of death (DCDD) organs has increased steadily over the last few years and now accounts for 20% of UK transplant activity. The procurement of DCDD livers is actively promoted as a means of increasing the donor pool and bridging the evolving disparity between the wait‐list length and the number of transplants performed. The objective of this retrospective study of a cohort of patients who were matched for age, liver disease etiology, and Model for End‐Stage Liver Disease score was to determine whether differences in perioperative costs and resource utilization are associated with the use of such organs. Our results showed an increased prevalence of reperfusion syndrome in the DCDD cohort (P < 0.001), a prolonged heparin effect (P = 0.01), a greater incidence of hyperfibrinolysis (P = 0.002), longer periods of postoperative ventilator use (P = 0.03) and vasopressor support (P = 0.002), and a prolonged length of stay in the intensive therapy unit (ITU; P = 0.02). The peak posttransplant aspartate aminotransferase level was higher in the DCDD group (P = 0.007), and there was significantly more graft failure at 12 months (P = 0.03). In conclusion, we have demonstrated different perioperative and early postoperative courses for DCDD and donation after brain death (DBD) liver transplants. The overall quality of DCDD grafts is poorer; as a result, the length of the ITU stay and the need for multiorgan support are increased, and this has significant financial and resource implications. We believe that these implications require a careful real‐life consideration of benefits. It is essential for DCDD not to be seen as a like‐for‐like alternative to DBD and for every effort to be continued to be made to increase the number of donations from brain‐dead patients as a first resort.

Interrelationships between densitometric, geometric, and mechanical properties of rat femora: Inferences concerning mechanical regulation of bone modeling

A compensation for differences in bone material qualtiy by bone geometric properties in femora from two different strains of rats was previously shown by us. A feedback mechanism controlling the mechanical properties of the integrated bones was then proposed, in accordance with Frost's mechanostat theory. Evidence of such a system is now offered by the finding of a negative correlation between the modeling‐dependent cross‐sectional architecture (moment of inertia) and the mineral‐dependent stiffness (elastic modulus) of bone material in the femoral diaphyses of 45 normal Wistar rats of different sexes, ages, and sizes. The strength and stiffness of the integrated diaphyses were found to depend on both cross‐sectional inertia and body weight, not on bone mineral density. These findings are interpreted as supporting the hypothesis that the architectural efficiency of diaphyseal cross‐sectional design resulting from the spatial orientation of bone modeling during growth is optimized as a function of the body weight‐dependent bone strain history, within the constraints imposed by bone stiffness. Results suggest a modulating role of biomass, related to the system set point determination, and explain the usually observed lack of a direct correlation between mineral density and strength or stiffness of long bones in studies of geometrically inhomogeneous populations.
Intrapartum fetal heart rate assessment

Normal human labor is characterized by regular uterine contractions and repeated episodes of transient interruption of fetal oxygenation. Most fetuses tolerate this process well, but some do not. The fetal heart rate (FHR) pattern helps to distinguish the former from the latter as it is an indirect marker of fetal cardiac and central nervous system responses to changes in blood pressure, blood gases, and acid-base status. (See "Nonstress test and contraction stress test", section on 'Physiologic basis of fetal heart rate changes'.)
Postpartum Depression Among African-American Women

The purpose of this qualitative study was to describe the nature of postpartum depression (PPD) among African-American women. Twelve women, who had experienced PPD within the last three years, were interviewed for approximately one hour at two intervals. Nudist-4 software and the constant comparative method were used to analyze the data. Five themes "Stressing Out," "Feeling Down," "Losing It," "Seeking Help," and "Feeling Better" represented aspects of PPD as experienced by the participants. The last theme, "Dealing with It," represented the cultural ways in which African-American mothers managed their depression. These included Keeping the Faith, Trying to Be a Strong Black Woman, Living with Myths, and Keeping Secrets. Suggestions for future directions in nursing research are included.
Do Masculine Men Smell Better? An Association Between Skin Color Masculinity and Female Preferences for Body Odor

A recent study claimed face skin color as a sexually dimorphic variable that influences attractiveness preferences in mate choice. Thereby, skin color may assume the role of a mate quality signal influencing attractiveness preferences. As body odor is linked to attractiveness, this study aimed to explore whether the odors of men with more masculine facial skin color would be evaluated more positively than odors from less masculine men. Female raters were presented with body odors of 18 men and were asked to rate them in various characteristics. Multilevel modeling revealed that the odors of the donors with more masculine color were rated not only as more attractive, more pleasant, and sexier, but also healthier. This indicates that odor associated with men with more masculine skin color is attractive, just as other sexually dimorphic traits. Furthermore, we found a negative relation between skin color masculinity and perceived odor maleness. Regarding this last finding, a new discussion is introduced with respect to the influence of cognitive stereotypes in odor judgments. Altogether, the study supports the possibility that chemosensory signals may be communicating signs of mate quality associated with masculinity.
Modeling of Porous Liner Using CE / SE Method with Application to Duct Aeroacoustics

This paper proposes a new numerical modeling approach for porous liner with application to duct aeroacoustics which is different from classical impedance modeling of the lined surface. Direct aeroacoustic simulation (DAS) is adopted to describe the flow dynamics and acoustics inside porous liner by solving unsteady compressible Navier-Stokes equations with source terms that model the porous effect. Brinkman penalization method and Brinkman-Forchheimer-extended Darcy model are attempted to model the flow in porous medium. The single domain formulation eliminates the need to specify boundary conditions at fluid and porous interface explicitly. The in-house DAS code based on space-time conservation element and solution element (CE/SE) scheme is implemented to resolve low Mach number duct aeroacoustic problems with porous liner. The validation approaches and results are reported in this paper.
Dividend policy and stock returns: Evidence from Jordan

The purpose of this study is to examine the empirical relationship between the two dividend policy measures (dividend yield and dividend payout ratio) and the stock return, after controlling for the excess return on the market, the size of the firm, financial leverage, and the ratio of the book value per share to the market value per share in the context of the Jordanian stock market. All firms listed on the Amman Stock Exchange are selected for analysis over the period from 2002 to 2008. The unbalanced panel data (cross-sectional and time series) is used to examine the relationship between dividend policy and stock returns. The results of this study show a positive and significant relationship between dividend yield and stock return while stock return is inversely associated with dividend payout ratio. The contribution of this thesis is to reduce the dearth of previous research on dividend policy in emerging markets regarding the empirical relationship between dividend policy and stock return.
From Siti Zubaidah Lyric to Character Identification and Storyline Writing for Local Culture Revitalization

Students of English Education Study Program read and learn English literature and some Palembang legends in their literature class. However, they never read lyric as local or traditional literature which is written in Melayu. In order to revitalize the local culture, they were introduced with the beautiful rhymes they never learnt before. They have to read and understand 3822 lyrics of Siti Zubaidah. This study aimed to investigate the students’ ability in: (1) identifying the characters; (2) arranging story line after paraphrasing the lyrics; and (3) perceiving the importance of the lyrics as a revitalized local culture. Using descriptive qualitative method as one of the method used in this R and D research design with 41 students of the fifth semester as the sample, the researchers collected the data in forms of documentation, questionnaire, and interview. The data were analyzed by using percentage analysis and rubric of story writing. The results of this study showed that: (1) from the data, there were 37% or 15 students who categorized as Very Good, meanwhile there were 63% students who categorized as Excellent in identifying the characters of the lyric, (2) the storylines arranged by the students were categorized as good enough with the average score was 70, and (3) there were 66 % or 23 students who positively perceived the importance of lyric for the local culture revitalization. Keywords— lyric, character identification, storyline, local culture revitalization
Text entry tap accuracy and exploration of tilt controlled layered interaction on Smartwatches

Design of text entry on small screen devices, e.g. smartwatches, faces two related challenges: trading off a reasonably sized keyboard area against space to display the entered text and the concern over "fat fingers". This paper investigates tap accuracy and revisits layered interfaces to explore a novel layered text entry method. A two part user study identifies preferred typing and reading tilt angles and then investigates variants of a tilting layered keyboard against a standard layout. We show good typing speed (29 wpm) and very high accuracy on the standard layout - contradicting fears of fat-fingers limiting watch text-entry. User feedback is positive towards tilting interaction and we identify ∼14° tilt as a comfortable typing angle. However, layering resulted in slightly slower and more erroneous entry. The paper contributes new data on tilt angles and key offsets for smartwatch text entry and supporting evidence for the suitability of QWERTY on smartwatches.
Prevalence of gastrointestinal parasites in cattle at Vangura upazila in Pabna district of Bangladesh

A survey on gastrointestinal parasitic infections in cattle was conducted at Vangura upazila, Pabna district, Bangladesh during the period from July to November, 2012 using coproscopy. The effects of age and sex on the prevalence of parasitic infections were determined. Among 170 fecal samples examined, 133 (78.24%) were found positive for parasitic infections and mean egg per gram of feces (EPG) was 403.01±31.82. The parasites identified on fecal examinations were snail borne trematodes namely, Fasciola gigantica (4.11%), amphistomes (40%), Schistosoma spp. (5%), nematodes namely, Haemonchus sp. (3.52%), Strongyles (1.17%), Strongyloides (1.17%), Trichuris sp. (1.76%), Dictyocaulus sp. (0.58%) and cestodes Moniezia spp. (3.52%), and protozoal infections namely, Balantidium coli (41.76%) and Eimeria spp. (4.11%). Age between calf and adult cattle had significant (p<0.05) influence on the infections with the gastro-intestinal parasites, whereas the sex of the cattle had no significant effect. Lower infection with Moniezia spp. (3.33%) was found in young cattle than in the adults (4.08%). Higher rate of infections was also recorded in females (78.83%) than in the males (75.76%). However, the present study demonstrated that age and sex of cattle had significant influence on the prevalence of gastrointestinal parasitic infection.
