Metallographic Image Fusion
Image processing plays important role in manufacturing, aerospace, biomedical fields. To determine the classification of metallic sample, edge structure and images without blur are required. Instead of finding the noise kernel blur section of images can be removed by using multiple images fusion. There are different methods used for image fusions like average method, maxima, wavelet transform. For image fusion discrete wavelet transform is used. Image fusion improves the quality of image, data content. In this paper three images are used to fuse together. This images having standard size of 640x480 pixels. Image fusion improves the quality so that edge structure can be determined. According to edge structure the classification is done using ASTME standards
Limited Relationship between Cervico-Vaginal Fluid Cytokine Profiles and Cervical Shortening in Women at High Risk of Spontaneous Preterm Birth
Objective: to determine the relationship between high vaginal pro-inflammatory cytokines and cervical shortening in women at high risk of spontaneous preterm labor and to assess the influence of cervical cerclage and vaginal progesterone on this relationship. Methods: this prospective longitudinal observational study assessed 112 women with at least one previous preterm delivery between 16 and 34 weeksâ gestation. Transvaginal cervical length was measured and cervico-vaginal fluid sampled every two weeks until 28 weeks. If the cervix shortened (<25 mm) before 24 weeksâ gestation, women (cases) were randomly assigned to cerclage or progesterone and sampled weekly. Cytokine concentrations were measured in a subset of cervico-vaginal fluid samples (nâ=â477 from 78 women) by 11-plex fluid-phase immunoassay. Results: all 11 inflammatory cytokines investigated were detected in cervico-vaginal fluid from women at high risk of preterm birth, irrespective of later cervical shortening. At less than 24 weeksâ gestation and prior to intervention, women destined to develop a short cervix (nâ=â36) exhibited higher cervico-vaginal concentrations than controls (nâ=â42) of granulocyte-macrophage colony-stimulating factor [(GM-CSF) 16.2 fold increase, confidence interval (CI) 1.8â147; pâ=â0.01] and monocyte chemotactic protein-1 [(MCP-1) 4.8, CI 1.0â23.0; pâ=â0.05]. Other cytokines were similar between cases and controls. Progesterone treatment did not suppress cytokine concentrations. Interleukin (IL)-6, IL-8, granulocyte colony-stimulating factor (G-CSF), interferon (IFN)-Îł and tumour necrosis factor (TNF)-α concentrations were higher following randomization to cerclage versus progesterone (p<0.05). Cerclage, but not progesterone treatment, was followed by a significant increase in cervical length [mean 11.4 mm, CI 5.0â17.7; p<0.001]. Conclusions: although GM-CSF and MCP-1 cervico-vaginal fluid concentrations were raised, the majority of cervico-vaginal cytokines did not increase in association with cervical shortening. Progesterone treatment showed no significant anti-inflammation action on cytokine concentrations. Cerclage insertion was associated with an increase in the majority of inflammatory markers and cervical length
The Cockayne Syndrome Natural History (CoSyNH) study:clinical findings in 102 individuals and recommendations for care
Purpose:
Cockayne syndrome (CS) is a rare, autosomal-recessive disorder characterized by microcephaly, impaired postnatal growth, and premature pathological aging. It has historically been considered a DNA repair disorder; fibroblasts from classic patients often exhibit impaired transcription-coupled nucleotide excision repair. Previous studies have largely been restricted to case reports and small series, and no guidelines for care have been established.
Methods:
One hundred two study participants were identified through a network of collaborating clinicians and the Amy and Friends CS support groups. Families with a diagnosis of CS could also self-recruit. Comprehensive clinical information for analysis was obtained directly from families and their clinicians.
Results and Conclusion:
We present the most complete evaluation of Cockayne syndrome to date, including detailed information on the prevalence and onset of clinical features, achievement of neurodevelopmental milestones, and patient management. We confirm that the most valuable prognostic factor in CS is the presence of early cataracts. Using this evidence, we have created simple guidelines for the care of individuals with CS. We aim to assist clinicians in the recognition, diagnosis, and management of this condition and to enable families to understand what problems they may encounter as CS progresses
Children's and adolescents' rising animal-source food intakes in 1990-2018 were impacted by age, region, parental education and urbanicity
Animal-source foods (ASF) provide nutrition for children and adolescents physical and cognitive development. Here, we use data from the Global Dietary Database and Bayesian hierarchical models to quantify global, regional and national ASF intakes between 1990 and 2018 by age group across 185 countries, representing 93% of the worlds child population. Mean ASF intake was 1.9 servings per day, representing 16% of children consuming at least three daily servings. Intake was similar between boys and girls, but higher among urban children with educated parents. Consumption varied by age from 0.6 at <1 year to 2.5 servings per day at 1519 years. Between 1990 and 2018, mean ASF intake increased by 0.5 servings per week, with increases in all regions except sub-Saharan Africa. In 2018, total ASF consumption was highest in Russia, Brazil, Mexico and Turkey, and lowest in Uganda, India, Kenya and Bangladesh. These findings can inform policy to address malnutrition through targeted ASF consumption programmes. (c) 2023, The Author(s)
Incident type 2 diabetes attributable to suboptimal diet in 184 countries
The global burden of diet-attributable type 2 diabetes (T2D) is not well established. This risk assessment model estimated T2D incidence among adults attributable to direct and body weight-mediated effects of 11 dietary factors in 184 countries in 1990 and 2018. In 2018, suboptimal intake of these dietary factors was estimated to be attributable to 14.1 million (95% uncertainty interval (UI), 13.814.4 million) incident T2D cases, representing 70.3% (68.871.8%) of new cases globally. Largest T2D burdens were attributable to insufficient whole-grain intake (26.1% (25.027.1%)), excess refined rice and wheat intake (24.6% (22.327.2%)) and excess processed meat intake (20.3% (18.323.5%)). Across regions, highest proportional burdens were in central and eastern Europe and central Asia (85.6% (83.487.7%)) and Latin America and the Caribbean (81.8% (80.183.4%)); and lowest proportional burdens were in South Asia (55.4% (52.160.7%)). Proportions of diet-attributable T2D were generally larger in men than in women and were inversely correlated with age. Diet-attributable T2D was generally larger among urban versus rural residents and higher versus lower educated individuals, except in high-income countries, central and eastern Europe and central Asia, where burdens were larger in rural residents and in lower educated individuals. Compared with 1990, global diet-attributable T2D increased by 2.6 absolute percentage points (8.6 million more cases) in 2018, with variation in these trends by world region and dietary factor. These findings inform nutritional priorities and clinical and public health planning to improve dietary quality and reduce T2D globally. (c) 2023, The Author(s)
Bone mineral content in growth hormone deficient children treated with growth hormone after withdrawal of supplementation with calcium, vitamin D and zinc
Superconductivity of binary and ternary compounds of Bi
Binary and ternary compounds of Bi formed with 3d transition elements Ni, Co, Fe, and Cr have been studied. Resistance behavior at low temperatures shows two superconducting transitions, one between 4 and 5 K and the other at 10.3 K. Resistance data above Tc up to about 25 K reveal a temperature exponent of 2 for higher Tc samples and 3 when Tc is lower. ESR studies seem to indicate an increase in the density of states at EF. Results are discussed in terms of various models based on the Landau Fermi-liquid theory and the observed data are interpreted in terms of spin-density-fluctuation model
Dietary patterns with special reference to calcium intake in 2â16-year-old Urban Western Indian children
Background: It is important to establish good dietary practices in childhood that promote adequate calcium intake throughout life and reduce the risk of osteoporotic fractures in later life. Objectives: To assess dietary patterns of 2â16-year-old children with special reference to calcium and suggest strategies and develop recipes suitable to identified patterns to increase dietary calcium intake. Methods: We studied 220 schoolchildren (2â16 years) around Pune city, India. The study duration was June 2013âJuly 2014. Height and weight were measured using standard protocols. Dietary intake was assessed by 24-h diet recall on 3 nonconsecutive days. Dietary patterns were derived by cluster analysis in two age groups; children (2â9 years) and adolescents (10â16 years). As per the dietary patterns, calcium-rich recipes were developed. Results: Among children, ârice-pulseâ (RP) and âwheat, milk, and milk productsâ (WM) patterns were observed. Among adolescents, RP, âwheat, milk, and bakeryâ (WMB), and âmixed foodâ patterns were observed. Children who consumed âWMâ and âWMBâ patterns had greater intake of calcium (P < 0.05) than children consuming other dietary patterns. The daily calcium intake of whole group was 53% of the recommended dietary allowance. From this, 30% calcium came from milk. Each serve of the developed recipe provided an average of 254 mg of calcium. Conclusion: Majority of children had cereal-pulse-based dietary patterns. By replacing foods from existing dietary patterns with calcium-rich foods, the dietary calcium content may be increased in a sustainable manner
