Impact of obesity on fetomaternal outcome in pregnant saudi females.

BACKGROUND Obesity is rapidly increasing in most populations of the world including Saudi community. Maternal obesity adversely impacts pregnancy outcome through increased rates of hypertensive disease, diabetes, cesarean section and infections. OBJECTIVES The aim of this study is to determine frequency of obesity and its adverse effects on reproductive outcome in pregnant Saudi females. METHODS Prospective Cohort study. Eight months (Nov 2008 to June 2009), Maternity and Children Hospital (MCH) Buraida, Saudi Arabia Sample included a group of 1000 randomly recruited pregnant Saudi females. Patients were admitted through Outpatient and Emergency Departments. Height was recorded once and weight twice; at the beginning (prepregnancy weight) and end of pregnancy. The difference between the two weights was taken as net weight gain in pregnancy. Prepregnancy weight was used to calculate Body mass index (BMI) using formula; Weight in Kg/Height in (m). 2 The sample was divided into 5 groups depending upon their BMI ;< 18.5, 18.5-24.9, 25-29.9, 30-39.9 &>40, classified as underweight, normal weight, overweight, obese & morbidly obese respectively. The normal weight group was used as control group. Data were collected regarding complications of obesity in pregnancy and labor and recorded on a Performa. Results were calculated by using computer programme SPSS Version 13 for windows. A p-value of< 0.05 is used to calculate statistical significance. RESULTS The frequency of weight distribution in pregnant Saudi female calculated to be 2% (lean), 31% (normal weight), 33%(overweight), 30%(obese) and 4%(morbidly obese). Compared with normal weight women, both overweight and obese women had a significantly increased risk (p-value-<0.05) for gestational diabetes, preeclampsia, cesarean delivery, and delivery of a macrocosmic infant. CONCLUSION Overweight & obesity is a growing problem in pregnant Saudi females associated with increased risks of fetomaternal complications like preeclampsia, gestational diabetes, cesarean delivery, and delivery of a macrocosmic infant.
Voltage-Balancing Method for Stacked Multicell Converters Using Phase-Disposition PWM

This paper presents a voltage-balancing method for stacked multicell converters (SMCs) based on phase disposition pulsewidth modulation. A cost function is evaluated to select the optimum state from a pool of redundant possible ones at each voltage level. It is demonstrated that, if sawtooth carriers are used for modulation instead of standard triangular ones, significant reduction in the switching frequency and the associated power losses of the power devices can be achieved without affecting the voltage-balancing capability. Experimental results from a seven-level SMC laboratory prototype are provided to verify the proposed voltage-balancing method against linear and nonlinear loads, as well as under transient conditions.
Reprints Available Directly from the Publisher Photocopying Permitted by License Only Proteolytic Activity of Human Lymphoid Tumor Cells. Correlation with Tumor Progression

Matrix metalloproteinase (MMP) expression and production are associated with advanced-stage tumor and contribute to tumor progression, invasion and metastases. The current study was designed to determine the expression and production of MMP-2 (gelatinase A) and MMP-9 (gelatinase B) by human lymphoid tumor cells. Changes in expression and production were also investigated during tumor progression of multiple myeloma and mycosis fungoides. In situ hybridization analysis revealed that lymphoblastic leukemia B cells (SB cell line), multiple myeloma (MM) cells (U266 cell line) and lymphoblastic leukemia T cells (CEM and Jurkat cell lines) express constitutively the mRNA for MMP-2 and/or MMP-9. We demonstrated by gelatin-zymography of cell culture medium that both enzymes were secreted in their cleaved (activated) form. In situ hybridization of bone marrow plasma cells and gela-tin-zymography of the medium showed that patients with active MM (diagnosis, relapse, leukemic progression) express higher levels of MMP-2 mRNA and protein than patients with non-active MM (complete/objective response, plateau) and with monoclonal gammopathies of undetermined significance (MGUS). MMP-9 expression and secretion was similar in all patient groups. In patients with mycosis fungoides (MF), the expression of MMP-2 and MMP-9 mRNAs was significantly upregulated with advancing stage, in terms of lesions both positive for one of two mRNAs and with the greatest intensity of expression. Besides MF cells, the MMP-2 and/or MMP-9 mRNAs were expressed by some stromal cell populations (microvascular endothelial cells, fibroblasts, macrophages), suggesting that these cells cooperate in the process of tumor invasion. Our studies identify MMPs as an important class of proteinases involved in the extracellular matrix (ECM) degradation by human lymphoid tumors, and suggest that MMPs inhibitors may lead to important new treatment for their control. 77 78 ANGELO VACCA et al.
Association Between Retinol-Binding Protein 4 Concentrations and Gestational Diabetes Mellitus and Risk of Developing Metabolic Syndrome After Pregnancy

The aim of this study was to examine the association between plasma retinol-binding protein 4 (RBP4) and gestational diabetes mellitus (GDM) and the risk of developing metabolic syndrome after pregnancy. In a case-control study, 192 pregnant women (92 with GDM) were recruited. Gestational diabetes mellitus was diagnosed based on O’Sullivan and Mahan criteria. In all pregnancies, plasma RBP4 concentrations were measured. Retinol-binding protein 4 concentrations in GDM patients were significantly higher than the normal women. Retinol-binding protein 4 level equal to or more than 42 μg/mL could help predict the risk of developing GDM (sensitivity = 75.8%, specificity = 65.3%, P = .001). Concerning metabolic syndrome after pregnancy, in all participants, the prevalence of metabolic syndrome base on World Health Organization (WHO) criteria was 24%. After pregnancy, 32.6% of women with GDM had metabolic syndrome compared with 10.5% of those with healthy pregnancy (P = .001). Age more than 25 years, body mass index (BMI) more than 27 kg/cm2, and RBP4 concentrations were independent risk factors for GDM. Measurement of RBP4 together with the assessment of other risk factors could help identify women at risk of developing GDM.

In addition, the flexibility of the software makes it easy to consolidate Internet of Things (IoT) and industrial workloads in ways that help industrial customers gain greater insight from data.
Otitis media with effusion.

Otitis media with effusion (OME), also called glue ear, is characterised by a collection of fluid in the middle-ear cleft. there is chronic inflammation but without signs of acute inflammation. OME is the most common cause of hearing impairment (and the most common reason for elective surgery) in childhood, where it usually follows an episode of acute otitis media (AOM). It is uncommon in adults, in whom Eustachian tube dysfunction is the predominant cause and suspicious aetiologies should be considered. [1]
Structural stiffness and Coulomb damping in compliant foil journal bearings : parametric studies

This paper presents the results of the second part of the investigation on structural stiffness and Coulomb damping in compliant foil journal bearings. In the first part, a theoretical model was developed to calculate equivalent viscous damping coefficients and structural stiffness of a bump foil strip in a journal bearing or damper. A computer program was also developed to compute the eccentricity and attitude angle of the journal static equilibrium position as well as the deflections, displacements, reacting forces, and equivalent friction coefficient of each bump on the strip. This model and program enabled further parametric studies to be conducted in the second part of the investigation, the results of which are the subject of this paper. The design parameters studied were static eccentricity (bearing load), pad angle (load angle), sliding friction coefficients, and perturbation amplitude (dynamic load). In addition, more effective methods of achieving both Coulomb damping and optimum structural stif.
Cytotoxicity of Experimental Resin Composites on Mesenchymal Stem Cells Isolated from Two Oral Sources

Abstract Resin composite materials that are used to restore tooth cervical lesions associated with gingival recessions can hamper healing after root coverage surgeries. This study evaluates the in vitro cytotoxic effect of five resin composites (two commercial and three experimental) on oral mesenchymal stem cells (MSCs) and the persistence of stemness properties in high passage MSCs. Sorption and solubility tests were made for all materials. MSCs were isolated from re-entry palatal and periodontal granulation tissues and were characterized and cultured on composite discs. Cytotoxicity of the materials was evaluated by the Alamar Blue viability test, by Paul Karl Horan (PKH) labeling, and by immunocytochemical staining for actin. Water and saliva sorption and solubility data revealed that two of the experimental materials behaved comparable with the marketed resin composites. The Alamar Blue viability test shows that both cell lines grew well on composite discs that seemed to induce no apparent toxic effects. No signs of disruption of cytoskeleton organization was seen. Experimental resin composites can be recommended for further investigation for obtaining approval for use. The standard minimal criteria were fulfilled for high passage MSCs. Palatal tissue regains its regenerative properties in terms of MSC presence in the re-entry area after 6 months of healing.
Evaluation of the microstructure and mechanical properties of friction stir welded 6005 aluminum alloy

Abstract The microstructural change related with the hardness profile has been evaluated for friction stir welded, age hardenable 6005 Al alloy. Frictional heat and plastic flow during friction stir welding created fine and equiaxed grains in the stir zone (SZ), and elongated and recovered grains in the thermomechanically affected zone (TMAZ). The heat affected zone (HAZ), identified only by the hardness result because there is no difference in grain structure compared to the base metal, was formed beside the weld zone. A softened region was formed near the weld zone during the friction stir welding process. The softened region was characterised by the dissolution and coarsening of the strengthening precipitate during friction stir welding. Sound joints in 6005 Al alloys were successfully formed under a wide range of friction stir welding conditions. The maximum tensile strength, obtained at 507 mm min-1 welding speed and 1600 rev min-1 tool rotation speed, was 220 MPa, which was 85% of the strength of the base metal.
A Reevaluation of the Electrophysiological Correlates of Expert Object Processing

Subordinate-level object processing is regarded as a hallmark of perceptual expertise. However, the relative contribution of subordinate- and basic-level category experience in the acquisition of perceptual expertise has not been clearly delineated. In this study, participants learned to classify wading birds and owls at either the basic (e.g., wading bird, owl) or the subordinate (e.g., egret, snowy owl) level. After 6 days of training, behavioral results showed that subordinate-level but not basic-level training improved subordinate discrimination of trained exemplars, novel exemplars, and exemplars from novel species. Event-related potentials indicated that both basic- and subordinate-level training enhanced the early N170 component, but only subordinate-level training amplified the later N250 component. These results are consistent with models positing separate basic and subordinate learning mechanisms, and, contrary to perspectives attempting to explain visual expertise solely in terms of subordinate-level processing, suggest that expertise enhances neural responses of both basic and subordinate processing.
Commercial applications of natural language processing

Vast quantities of text are becoming available in electronic form, ranging from published documents (e.g., electronic dictionaries, encyclopedias, libraries and archives for information retrieval services), to private databases (e.g., marketing information, legal records, medical histories), to personal email and faxes. Online information services are reaching mainstream computer users. There were over 15 million Internet users in 1993, and projections are for 30 million in 1997. With media attention reaching all-time highs, hardly a day goes by without a new article on the National Information Infrastructure, digital libraries, networked services, digital convergence or intelligent agents. This attention is moving natural language processing along the critical path for all kinds of novel applications.
Evaluation of TSV and micro-bump probing for wide I/O testing

Practical silicon stacking requires pre-tested dies, but contact probing of TSV interconnects requires much higher density, lower probing forces, and lower cost per pin than conventional probe cards have achieved. This paper examines a cost-effective, lithographic-based MEMS probe card technology that is suitable for probing 40µm pitch arrays, and scalable to finer pitches. Initial mechanical and electrical results are presented, demonstrating the feasibility of probing large arrays at 1 gram-force per tip with very low pad damage, so as not to impair downstream bonding or other processing steps.

Evaluation the effects of hoof trimming on bovine leg score improvement and its distribution.

Objective- Evaluation of leg scoring as a method for hoof trimming neccesity. Design- Prospective randomised trial. Animals- Hundred and sixty holstein dairy cows. Procedure- One hundred and fifty cows selected in a dairy farm in dry period 2-3 weeks before calving (stage one), all cows were photographed, right, left and overall scores (A three point scoring system, in which score one is for normal cows and score three is for extremely outward rotated hindfeet) was given by 5 observers. Cows were photographed 30 days after parturition (Stage two), Days in Milk (DIM) 120 (Stage three) and DIM 150 (Stage four). Agreement of the observers in different stages, and leg score changes during time was evaluated using one way ANOVA. Distribution of leg scores in different stages compared using Chi-square test. Results- No statistical difference was recorded between observers in each stages except stage two. The highest score was recorded in stage one (2.08±0.72) and the lowest recorded in stage two (1.56±0.64). After parturition overall score increased till 120 DIM (1.8±0.71) but no significant changes recorded by increasing DIM (1.85±0.74) and after hoof trimming. Distribution of score three cows were reduced significantly in stage two in comparison to stage one and increase significantly in stage three in comparison to stage two. No statistical difference recorded between stages three and four. The average number of cows in score three were 27.1, 5.3, 19.2, and 21.2 percent in stages one to four respectively that is higher than previously reported numbers. Conclusion and Clinical Relevance- Leg scoring in cows with equal days in milk is useful. Hoof trimming cannot reduce leg scores but can prevent its growing trend.
Evaluation of the pediatric craniocervical junction on MDCT.

OBJECTIVE The purpose of our study was to establish normal values on MDCT images for the measurement of various craniocervical junction relationships in children and to address discrepancies in the literature based on radiographic values. MATERIALS AND METHODS Accepted methods of evaluating the craniocervical junction were used to calculate normal values in 117 normal children on MDCT images with multiplanar reconstructions. The basion-axial interval, basion-dens interval, Powers ratio, atlantodental interval, and atlantooccipital interval were measured in each patient and compared with accepted data based on radiographs. RESULTS The basion-axial interval was difficult to reproduce on MDCT images. In 97.5% of patients, the basion-dens interval was less than 10.5 mm compared with 12 mm based on data from radiographs. Separating the patient population into those in whom the os terminale was ossified and those in whom it was not revealed a difference of 2 mm in the upper limit of normal (9.5 and 11.6 mm, respectively). The Powers ratio showed no significant difference compared with data obtained using radiographs. In 97.5% of the population, the atlantodental interval was less than 2.6 mm, compared with 4-5 mm measured on radiographs. The atlantooccipital interval showed 97.5% of the population falling below 2.5 mm at any point in the joint space, compared with the previously accepted value of 5 mm. CONCLUSION Normal values for the craniocervical junction articulations and relationships as seen on MDCT are different from the accepted ranges of normal based on radiographs. The values should be considered the normal values in the pediatric population on MDCT.
Sleep apnea in 81 ambulatory male patients with stable heart failure. Types and their prevalences, consequences, and presentations.

BACKGROUND Heart failure is a highly prevalent disorder that continues to be associated with repeated hospitalizations, high morbidity, and high mortality. Sleep-related breathing disorders with repetitive episodes of asphyxia may adversely affect heart function. The main aims of this study were to determine the prevalence, consequences, and differences in various sleep-related breathing disorders in ambulatory male patients with stable heart failure. METHODS AND RESULTS This article reports the results of a prospective study of 81 of 92 eligible patients with heart failure and a left ventricular ejection fraction < 45%. There were 40 patients without (hourly rate of apnea/hypopnea, 4 +/- 4; group 1) and 41 patients with (51% of all patients; hourly rate of apnea/hypopnea, 44 +/- 19; group 2) sleep apnea. Sleep disruption and arterial oxyhemoglobin desaturation were significantly more severe and the prevalence of atrial fibrillation (22% versus 5%) and ventricular arrhythmias were greater in group 2 than in group 1. Forty percent of all patients had central sleep apnea, and 11% had obstructive sleep apnea. The latter patients had significantly greater mean body weight (112 +/- 30 versus 75 +/- 16 kg) and prevalence of habitual snoring (78% versus 28%). However, the hourly rate of episodes of apnea and hypopnea (36 +/- 10 versus 47 +/- 21), episodes of arousal (20 +/- 14 versus 23 +/- 11), and desaturation (lowest saturation, 72 +/- 11% versus 78 +/- 12%) were similar in patients with these different types of apnea. CONCLUSIONS Fifty-one percent of male patients with stable heart failure suffer from sleep-related breathing disorders: 40% from central and 11% from obstructive sleep apnea. Both obstructive and central types of sleep apnea result in sleep disruption and arterial oxyhemoglobin desaturation. Patients with sleep apnea have a high prevalence of atrial fibrillation and ventricular arrhythmias.
Low morning serum cortisol levels in children with tonsillar hypertrophy and moderate-to-severe OSA.

BACKGROUND Hypertrophic tonsillar tissue in children with obstructive sleep apnea (OSA) has enhanced expression of glucocorticoid receptors, which may reflect low endogenous cortisol levels. We have evaluated the effect of the interaction between tonsillar hypertrophy and OSA severity on morning serum cortisol levels. METHODS Children with and without snoring underwent polysomnography, tonsillar size grading, and measurement of morning serum cortisol. RESULTS Seventy children (2-13 years old) were recruited: 30 with moderate-to-severe OSA (apnea-hypopnea index [AHI] > 5 episodes/h), 26 with mild OSA (AHI > 1 and ≤ 5), and 14 controls (no snoring; AHI ≤ 1). Tonsillar hypertrophy was present in 56.7%, 53.8%, and 42.9% of participants in each group, respectively. Application of a general linear model demonstrated a significant effect of the interaction between severity of OSA and tonsillar hypertrophy on cortisol levels (P = 0.04), after adjustment for obesity, gender, and age. Among children with tonsillar hypertrophy, subjects with moderate-to-severe OSA (n = 17; AHI 14.7 ± 10.6), mild OSA (n = 14; AHI 2.3 ± 1.2), and control participants (n = 6; AHI 0.7 ± 0.2) were significantly different regarding cortisol levels (P = 0.02). Subjects with moderate-to-severe OSA had lower cortisol (16.9 ± 8.7 mcg/dL) than those with mild OSA (23.3 ± 4.2; P = 0.01) and those without OSA (controls) (23.6 ± 5.3 mcg/dL; P = 0.04). In contrast, children with normal-size tonsils and moderate-to-severe OSA, mild OSA, and controls did not differ in cortisol levels. CONCLUSIONS Children with moderate-to-severe obstructive sleep apnea and the phenotype of hypertrophic tonsils have reduced morning serum cortisol levels and potentially decreased glucocorticoid inhibitory effects on tonsillar growth.
Minimally Infrequent Itemset Mining using Pattern-Growth Paradigm and Residual Trees

Itemset mining has been an active area of research due to its successful application in various data mining scenarios including finding association rules. Though most of the past work has been on finding frequent itemsets, infrequent itemset mining has demonstrated its utility in web mining, bioinformatics and other fields. In this paper, we propose a new algorithm based on the pattern-growth paradigm to find minimally infrequent itemsets. A minimally infrequent itemset has no subset which is also infrequent. We also introduce the novel concept of residual trees. We further utilize the residual trees to mine multiple level minimum support itemsets where different thresholds are used for finding frequent itemsets for different lengths of the itemset. Finally, we analyze the behavior of our algorithm with respect to different parameters and show through experiments that it outperforms the competing ones.
