From volumes to views: an approach to 3-D object recognition

The authors present an approach to the recovery and recognition of 3-D objects from a single 2-D image. Given a recognition domain consisting of a database of objects, they select a set of object-centered 3-D volumetric modeling primitives that can be used to construct the objects. They take the set of primitives and generate a hierarchical aspect representation based on their projected surfaces; conditional probabilities capture the ambiguity of mappings between levels of the hierarchy. From a region segmentation of the input image, they present a novel formulation of the recovery problem based on grouping the regions into aspects. Once the aspects are recovered, they use the aspect hierarchy to infer a set of volumetric primitives and their connectivity. The recovered primitives are then used as indices into the object database for recognition. <<ETX>>
Cultural Influence on Family Management of Children With Cancer

A family's cultural context directly influences how they define and manage their child's cancer. Knowing this dynamic can guide nurses in delivering holistic, culturally competent care. This literature review examines the international and domestic pediatric oncology research as it relates to the inclusion of family and cultural variables. Most international studies and comparative studies have investigated Asian cultures and found that health beliefs, communication beliefs, religious practice, and family structure are common themes of cultural influences on families. Additional studies within the United States are needed to explore cultural beliefs through carefully tailored family assessments. Implications for practice include the possibility of providing evidence-based culturally competent care to families of children with cancer.
Use of bovine milk concentrate containing antibody to rotavirus to treat rotavirus gastroenteritis in infants.

The use of a concentrate containing milk immunoglobulins prepared from rotavirus-hyperimmunized cows (neutralization titer, 1:6,000 for a 10% solution) to treat infants hospitalized for acute rotavirus gastroenteritis resulted in a significant (P = .008) reduction in the duration of excretion of virus. Stool samples from treated infants showed the presence of bovine milk immunoglobulins in 47% of cases and of neutralizing activity in 43% (mean neutralization titer, 1:48); stool samples from control infants showed neutralizing activities in only 3% of cases (neutralization titers, less than 1:20). Immunoelectrophoresis of stool extracts revealed fragment A, a bovine analogue of F(ab')2 or Fab, as the major product of in vitro and in vivo digestion of the immunoglobulins. Cessation of excretion of virus correlated with the appearance of neutralizing activities in 19 of 25 infants. Only concentrate-treated infants with high neutralizing activity in stools showed a statistically significant reduction in duration of excretion of virus; this duration in concentrate-treated infants with low neutralizing activity was comparable with controls.
The influence of plane of nutrition in early pregnancy on the survival and development of embryos in the sow.

Three groups of fifteen sows were given from the day following service 3, 6 or 9 lb meal a day until slaughter on the 28th day after mating. Mean weight gains were 6, 40 and 65 lb respectively. Five sows failed to conceive but there was no influence of treatment on conception rate. There was a significant relationship between number of corpora lutea and weight of sow at service (P<0\m=.\01)and between number of corpora lutea and number of normal embryos (P<0\m=.\001). When adjustment was made for differences in sow weight at service there were no significant effects of treatment on number of normal embryos or survival rate. Mean number of corpora lutea increased with plane of feeding but this difference between treatments was not significant. There were no treatment effects on either weight or crown\p=m-\ rump length of embryos, but the mean weight of embryonic membranes and mean volume of embryonic fluids were significantly greater on the low plane of feeding than on the medium and high planes (P <0\m=.\05).
Potential role of the early response gene c-myc in beta-cell adaptation to changes in glucose concentration.

Type 2 diabetes is characterized by a reduction in both insulin sensitivity and glucose-stimulated insulin secretion (GSIS). Although insulin resistance usually precedes � -cell dysfunction, the role of the latter in the development of the disease is unclear. The detrimental effect that chronic hyperglycemia exerts on � -cell function is well established and may contribute to further deterioration of GSIS during the development of type 2 diabetes. Islets from hyperglycemic 90%pancreatectomized rats display profound alterations in GSIS and � -cell gene expression. The association of these changes with � -cell hypertrophy and increased mRNA levels of the early response gene c-myc could reflect a loss of � -cell differentiation (1). The complete reversal of all these abnormalities upon correction of hyperglycemia by phlorizin treatment suggested hyperglycemia as their triggering factor. The aim of this study was to determine whether glucose directly regulates islet c-myc expression. Rat islets were cultured for 1‐7 days in RPMI medium containing 5, 10, 20, or 30 mmol/l glucose (G5‐G30) and 0.5% bovine serum albumin. Islet c-myc and TATA box binding protein (TBP) mRNA levels were measured by semiquantitative reverse transcriptase‐polymerase chain reaction. As compared with freshly isolated islets from the same preparation, the ratio of c-myc to TBP was increased approximately fivefold after overnight culture. This increase persisted after 3‐7 days in G5. In contrast, the c-myc‐to‐TBP ratio returned to control values after 7 days in G10‐G30. To avoid the confounding effect of the early increase in c-myc mRNA, probably due to stress of isolation, islets were first cultured for 7 days in G10 and then overnight in G5‐G30. When the glucose concentration was kept at 10 mmol/l, the c-myc‐to‐TBP ratio remained low and stable, whereas an approximate fivefold increase was observed after 1 day at either lower or higher glucose. In contrast, c-myc heterodimerization partner Max and its partner Mad1 were not affected by culture or glucose. The increase in islet c-myc‐to‐TBP ratio produced by high glucose was confirmed in rats maintained hyperglycemic (blood glucose >11 mmol/l) for 1‐4 days by glucose clamp (~200% of saline-infused rats). In contrast, fasting for 3 days reduced blood glucose to 3 mmol/l and modestly increased islet c-myc‐to‐TBP ratio to 132% of the ratio in fed rats. These results strongly suggest that both low and high glucose increase islet c-myc expression. Whereas the increase in low glucose could be related to the higher rate of apoptosis reported under this condition, the increase produced by high glucose could play a role in � -cell mass adaptation to hyperglycemia (replication/hypertrophy).
Detecting Frequency for Transient Signal Based on Wavelet Transform

The purpose of signal feature abstraction is to extract the substantial informations from the original data. This work proposes an appropriate approach in detecting local frequency of rapidly transient signal using wavelet transform. In particular, we make full use of the wavelet transform modulus maximum technique . Furthermore, a complete illustration of the theoretical background is provided underlying the measurement method. Simulation shows that this method is more effective than other known methods for frequency estimation.
Type 2 diabetes mellitus and obesity in sub‐Saharan Africa

While communicable diseases such as human immunodeficiency virus/acquired immune deficiency syndrome, malaria, and tuberculosis have continued to pose greater threats to the public health system in sub‐Saharan Africa (SSA), it is now apparent that non‐communicable diseases such as diabetes mellitus are undoubtedly adding to the multiple burdens the peoples in this region suffer. Type 2 diabetes mellitus (T2DM) is the most common form of diabetes (90–95%), exhibiting an alarming prevalence among peoples of this region. Its main risk factors include obesity, rapid urbanization, physical inactivity, ageing, nutrition transitions, and socioeconomic changes. Patients in sub‐Saharan Africa also show manifestations of β‐cell dysfunction and insulin resistance. However, because of strained economic resources and a poor health care system, most of the patients are diagnosed only after they have overt symptoms and complications. Microvascular complications are the most prevalent, but metabolic disorders and acute infections cause significant mortality. The high cost of treatment of T2DM and its comorbidities, the increasing prevalence of its risk factors, and the gaps in health care system necessitate that solutions be planned and implemented urgently. Aggressive actions and positive responses from well‐informed governments appear to be needed for the conducive interplay of all forces required to curb the threat of T2DM in sub‐Saharan Africa. Despite the varied ethnic and transitional factors and the limited population data on T2DM in sub‐Saharan Africa, this review provides an extensive discussion of the literature on the epidemiology, risk factors, pathogenesis, complications, treatment, and care challenges of T2DM in this region.

RanBPM Is a Phosphoprotein That Associates with the Plasma Membrane and Interacts with the Integrin LFA-1*

Integrin adhesion receptors can act as signaling receptors that transmit information from the extracellular environment to the interior of the cell, affecting many fundamental cellular processes, such as cell motility, proliferation, differentiation, and survival. Integrin signaling depends on the formation of organized sub-membrane complexes that comprise cytoskeletal, adapter, and signaling molecules. The identification of molecules that interact with the cytoplasmic domain of integrins has been the focus of research aimed to elucidating the mechanistic basis of integrin signal transduction. We have identified RanBPM as a novel interactor of the β2 integrin LFA-1 in a yeast-two-hybrid screen. In the same assay, RanBPM also interacted with the β1 integrin cytoplasmic domain. We demonstrate that RanBPM is a peripheral membrane protein and that integrins and RanBPM interact in vitro and in vivo and co-localize at the cell membrane. We find that RanBPM is phosphorylated on serine residues; phosphorylation of RanBPM is increased by stress stimuli and decreased by treatment with the p38 kinase inhibitor SB203580. Transfection of RanBPM synergizes with LFA-1-mediated adhesion in the transcriptional activation of an AP-1-dependent promoter, indicating that the two proteins interact functionally as well. We suggest that RanBPM may constitute a molecular scaffold that contributes to coupling LFA-1 and other integrins with intracellular signaling pathways.
REALIZATION OF PULSE SHAPING FIR INTERPOLATION FILTER USING VERILOG

Here This Optimization technique for designing are configurable VLSI architecture of an interpolation filter for multi-standard digital up converter ,To reduce the power and area consumption. Most of the area is occupied in the design of FIR filter the multiplier. The low current range and architecture of the pulse-shaping FIR filter for digital up converter was developed. In the existing system, the two bit binary common sub expression based binary common sub expression elimination algorithm and move and paste method was used to generate the partial products. In this paper carry adder is used instead of the shift and add method and the simple arithmetic adder multiplexer unit is replaced by the carry-save adder. The number of additions and multiplications can be reduced using this technique. This technique has been in reducing the managed area and power consumption by 43% and 38%, respectively, reported with 36% improvement in operating frequency over a 3-bit BCS-based technology, and can be considered adequate for designing more the multistandard DUC. The designed pulse shaping FIR filter synthesized and simulated using Xilinx ISE 6.9.
Oscillatory nature of human basal ganglia activity: Relationship to the pathophysiology of Parkinson's disease

Alterations of basal ganglia physiology in parkinsonism may consist of two elements, an increase in the firing rate of neurones and a change in the pattern of synchronisation of discharges between neurones. Recent findings suggest the presence of two principal modes of synchronised activity within the human subthalamo‐pallidal‐thalamo‐cortical circuit, at <30 Hz and >60 Hz. These oscillations are dynamically and systematically modulated by task, thereby suggesting a functional role in movement. More importantly, the two frequency modes are inversely affected by movement, consistent with opposing actions, and differentially expressed according to the prevailing level of dopaminergic activity. It is argued that the balance between these modes determines the effects of basal ganglia‐thalamocortical projections on the motor areas of the cortex. The lower frequency oscillations facilitate slow idling rhythms in the motor areas of the cortex, whereas synchronisation at high frequency restores dynamic task‐related cortical ensemble activity in the gamma band. © 2002 Movement Disorder Society
Effects of chest physical therapy on lung function in children recovering from acute severe asthma

The effects of chest physical therapy in acute severe asthma in children have been studied in 38 children aged 6 to 13 years in a randomized placebo controlled trial. The study began between 6 and 24 hours after admission to hospital; 19 children received chest physical therapy (PT) and 19 children received placebo visits. Each child had 4 treatments over 2 days which were preceded by nebulized salbutamol. Lung volumes and flow rates were measured in a body plethysmograph before salbutamol and before and after either PT or placebo on the first and fourth treatments. Throughout the study standard asthma drug therapy was given. In both groups characteristics such as sex, race, age, height, weight, severity, and baseline lung function were similar. Taking into account the baseline, lung function at the end of the study was similar in both groups. Three 12 year old children in the PT group showed improvements in flows above those seen in any children in the placebo group. We conclude that chest PT, when combined with asthma drug therapy, does not improve lung function in most children in this age group with acute severe asthma. Pediatr Pulmonal 1990; 9:146–151.
THE MICROBIOLOGICAL STATUS OF (READY TO EAT) LETTUCE BEFORE AND AFTER STANDARD WASHING

Lettuce is a vegetable that is always consumed raw. The number and types of microorganisms that may be found on the lettuce leaves depend on growing, harvesting, and particularly on handling practices, like proper washing and preparing lettuce before eating. The aim of this study was to investigate the effect that washing under running water has on the microbiological status of lettuce leaves purchased from the local market place in Banja Luka. Smears were taken from the obverse and reverse sides of lettuce leaves, and the total count of aerobic mesophilic bacteria, yeasts and molds was determined as well as the presence of sulphite-reducing clostridia, the coagulase positive staphylococci, Salmonella species, and Escherichia coli. The analysis showed that the washing reduced the total count of aerobic mesophilic bacteria by approximately 10 times, and the total count of yeasts and molds by approximately 8 times. Of the lettuce samples examined, 66,67% contained sulphite-reducing clostridia and 13,33% Salmonella species, before the washing. The number of samples with sulphite-reducing clostridia was reduced by five times after the washing, but the number of samples contaminated with Salmonella species remained the same.
Adaptively modeling multi-feature preferences for personalized search

This paper is concerned with the adaptation to multi-feature preferences on personalized search. In the existing work, the personalized search mainly leverages semantic features extracted from user history and ignores other non-semantic latent features, lets alone adapt to preference distribution on non-semantic features. To tackle this problem, we propose an adaptive model for multi-feature preferences, in which we adapt latent non-semantic features extracted from visited pages to reflect diverse aspects of user preferences. We also utilize a novel algorithm in our model to improve the adaptation for diverse preference distribution on these features for different users. Our experimental results demonstrate that our model can improve personalized search performance by enhanced adaptation to diverse user preferences.
Contribution to the food products' analysis: A research and evaluation on the hemolytic effect of some pesticides used in Lebanon

Pesticides are a real concern for the society as their use has become critical, leading sometimes to their accumulation as residues in fruits and vegetables. After examining the pesticides sold in Northern Lebanon, this study is focused on the analysis and identification of pesticides residues in fruits and vegetables that are harvested in this region and treated with the locally sold pesticides. Results show: first, (i) a use of Zineb by the name of another pesticide Micronized Sulfur to avoid prosecution; (ii) a significant presence of Metalaxyl in lemons and oranges; (iii) a significant presence of Trifluralin in strawberries; and (iv) a significant presence of Zineb in lemons and tomatoes. Second, with the use of hemolytic tests on human blood results show: (i) a critical concentration and a significant hemolytic effect of some pesticides used in Lebanon; and (ii) an absence of hemolytic effect in the collected fractions of the different analyzed fruit extracts containing pesticides. Finally, this work is the first step for pesticides' analysis in vegetables and fruits in Lebanon, initiating a wider analytical study in order to control and examine the use of pesticides which, according to our results, could have an adverse effect on human health over a long term.
Disturbance of the Determination of Germinal and Somatic Nuclei by Heat Shock in Paramecium caudatum

ABSTRACT During conjugation of Paramecium caudatum, nuclear determination occurs soon after the third postzygotic division: one of the four anterior nuclei becomes the micronucleus and the remaining three degenerate, while four posterior nuclei differentiate into macronuclear anlagen. Macronuclear differentiation is supposed to be dependent on a cytoplasmic differentiation factor. In this study, postzygotic cells were subjected to heat shock for 30 min and nuclear changes were observed by staining with carbol fuchsin solution. When heat shock was initiated during the period from metaphase to telophase of the third postzygotic division, cells showed an excess of macronuclear anlagen and were typically amicronucleate. Abnormal nuclear localization around the end of the third (last) postzygotic division may explain the origin of these kinds of cells. A similar phenomenon appeared after treatment with actinomycin D or emetine. Since heat shock did not inhibit macronuclear differentiation but destroyed the formation of micronuclei, some factor(s) probably plays an essential role in nuclear determination, especially in the protection of the micronuclei.
Fatal Lung Abscesses: Review of 11 Years' Experience

A review of the outcome of 440 patients hospitalized between 1967 and 1977 because of lung abscess showed that 41 died (case fatality rate = 9.3%). Major predisposing factors were present in many of the fatal and nonfatal cases. Advanced age and concomitant diseases were associated with a higher risk of death. Aspiration of contents of large cavities may have played a major role in the death of seven patients.
Adult-onset autosomal dominant leukodystrophy presenting with REM sleep behavior disorder

Adult-onset autosomal dominant leukodystrophy (ADLD) is a slowly progressive hereditary disease of the white matter caused by duplication of the nuclear lamina protein lamin B1 on chromosome 5q23.2. 1 Patients usually present in the 4th–5th decade with autonomic symptoms followed by pyramidal and cerebellar dysfunction.2 In ADLD, MRI head reveals symmetric T2-signal hyperintensities in the subcortical white matter, brainstem, and middle cerebellar peduncles.2 REM sleep behavior disorder (RBD) is a parasomnia characterized by dream enactment behavior and REM sleep without atonia.3 It has been reported most commonly with synucleinopathies such as Parkinson disease and may precede the diagnosis by decades.3 To our knowledge, RBD has not been reported with leukodystrophies. Herein we report a case of ADLD presenting with RBD as the initial symptom.

This work shows the development of a simulator from a virtualized environment, using strategies of image processing, and a game engine which offer support and functionalities needed to the simulation. Results with experimental data in normal traffic situations that shows the operation on real time, are also presented.
Coronary artery disease in women.

Women now outlive men by 10 years, thanks to the dramatic (>99%) decline in obstetrical death rate over the past 100 years. Women represent 60% of those over the age of 65 years in the United States (US) and more women than men have died of cardiovascular disease (CVD) since 1984. 1 There has been an explosive increase in the knowledge of the natural history of coronary artery disease (CAD) in women in the past decade. This is due to a combination of greater participation of women in research studies, improved medical technology, and perhaps political pressure. Among women, the lifetime risk of death from CAD is more than 10-fold greater than that from breast cancer. 2 It is estimated that 31% of women will die from CAD; yet, about 70% of university educated women consider their risk of CAD to be <1%. They worry profoundly about breast cancer, although the risk of death from breast cancer is <3%. This lack of concern for CAD by women and perhaps their physicians could explain why the decline of CAD in women in western countries has been only half that of men. The excess of CAD among overseas Indians has been similar or greater in women than in men, 3 and offers a broad “window to the world” for the impending epidemic of CAD among Indian women. In this article, the term “Indian” refers not only to people of Indian origin but all those originating from the entire Indian subcontinent. This review discusses the progress in understanding the major risk factors leading to the high rates of CAD in women, especially in India. The potential role of genetic susceptibility to CAD mediated by elevated lipoprotein (a) [Lp(a)] levels and its synergistic adverse effects with both conventional and emerging risk factors are highlighted. Important differences in the presentation, diagnosis and treatment of CAD in women, and the unique role of hormone replacement therapy (HRT) are addressed. Finally, we offer recommendations to both Indian women and their physicians in reducing the morbidity and mortality from CAD. Magnitude of CAD in Indian Women CAD rates in India: Since 1960, life expectancy in India has increased by 20 years to 61 years of age. 4 From 1960 to 1995, the prevalence of CAD in adults increased from 3% to 10% in urban Indians and from 2% to 4% in rural Indians, with women having rates similar to men. 5 Although the prevalence of CAD in rural India is half that of urban India, this is still two-fold higher than the overall CAD rates in the US and several-fold higher than in rural
