    Anemia is a common feature of diabetes and chronic kidney disease (CKD) mainly due to erythropoietin (EPO) deficiency and uremic toxicity. Angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) have been established as first-choice medications for the treatment of diabetic nephropathy. However, there are conflicting data regarding their impact on hemoglobin levels in patients with diabetic nephropathy. We evaluated the prevalence of anemia in 101 patients with diabetes mellitus type II and CKD at stage III-IV (group A) compared with 101 non-diabetic patients with similar renal function (group B). Moreover, we evaluated the impact of ACE inhibitors and ARBs on patients' anemia. Anemia was observed in 60 patients in group A and in 47 patients in group B (P patients in group A and 19 patients in group B were receiving exogenous EPO for correction of renal anemia (P patients in group A and 52 patients in group B were receiving ACE inhibitors and/or ARBs (P medications. Anemia is more common in diabetic patients with CKD stage III-IV than in non-diabetic patients with similar renal function. Our results indicate that ACE inhibitors and ARBs are not a significant cause of anemia for both populations.

    Background The most frequent form of congenital dyserythropoietic anemia is the type II form. Recently it was shown that the vast majority of patients with congenital dyserythropoietic anemia type II carry mutations in the SEC23B gene. Here we established the molecular basis of 42 cases of congenital dyserythropoietic anemia type II and attempted to define a genotype-phenotype relationship. Design and Methods SEC23B gene sequencing analysis was performed to assess the diversity and incidence of each mutation in 42 patients with congenital dyserythropoietic anemia type II (25 described exclusively in this work), from the Italian and the French Registries, and the relationship of these mutations with the clinical presentation. To this purpose, we divided the patients into two groups: (i) patients with two missense mutations and (ii) patients with one nonsense and one missense mutation. Results We found 22 mutations of uneven frequency, including seven novel mutations. Compound heterozygosity for a missense and a nonsense mutation tended to produce a more severe clinical presentation, a lower reticulocyte count, a higher serum ferritin level, and, in some cases, more pronounced transfusion needs, than homozygosity or compound heterozygosity for two missense mutations. Homozygosity or compound heterozygosity for two nonsense mutations was never found. Conclusions This study allowed us to determine the most frequent mutations in patients with congenital dyserythropoietic anemia type II. Correlations between the mutations and various biological parameters suggested that the association of one missense mutation and one nonsense mutation was significantly more deleterious that the association of two missense mutations. However, there was an overlap between the two categories. PMID:20015893

    Full Text Available The most frequent form of congenital dyserythropoiesis (CDA is congenital dyserythropoietic anemia II (CDA II. CDA II is a rare genetic anemia in humans, inherited in an autosomally recessive mode, characterized by hepatosplenomegaly normocytic anemia and hemolytic jaundice. Patients are usually transfusion-independent except in severe type. We are here reporting a case of severe transfusion-dependent type II congenital dyserythropoietic anemia in a 5-year-old patient who has undergone allogeneic hematopoietic stem cell transplantation (HSCT at our bone marrow transplantation centre. Patient has had up until now more than 14 mL/kg/month of packed cell volume (PCV, which he required every 15 to 20 days to maintain his hemoglobin of 10 gm/dL and hematocrit of 30%. His pre-HSCT serum ferritin was 1500 ng/mL and he was on iron chelating therapy. Donor was HLA identical sibling (younger brother. The preparative regimen used was busulfan, cyclophosphamide, and antithymocyte globulin (Thymoglobulin. Cyclosporine and short-term methotrexate were used for graft versus host disease (GVHD prophylaxis. Engraftment of donor cells was quick and the posttransplant course was uneventful. The patient is presently alive and doing well and he has been transfusion-independent for the past 33 months after HSCT.

    SEC23B gene encodes an essential component of the coat protein complex II (COPII)-coated vesicles. Mutations in this gene cause the vast majority the congenital dyserythropoietic anemia Type II (CDA II), a rare disorder resulting from impaired erythropoiesis. Here, we investigated 28 CDA II patients from 21 unrelated families enrolled in the CDA II International Registry. Overall, we found 19 novel variants [c.2270 A>C p.H757P; c.2149−2 A>G; c.1109+1 G>A; c.387(delG) p.L129LfsX26; c.1858 A>G p.M620V; c.1832 G>C p.R611P; c.1735 T>A p.Y579N; c.1254 T>G p.I418M; c.1015 C>T p.R339X; c.1603 C>T p.R535X; c.1654 C>T p.L552F; c.1307 C>T p.S436L; c.279+3 A>G; c. 2150(delC) p.A717VfsX7; c.1733 T>C p.L578P; c.1109+5 G>A; c.221+31 A>G; c.367 C>T p.R123X; c.1857_1859delCAT; p.I619del] in the homozygous or the compound heterozygous state. Homozygosity or compound heterozygosity for two nonsense mutations was never found. In four cases the sequencing analysis has failed to find two mutations. To discuss the putative functional consequences of missense mutations, computational analysis and sequence alignment were performed. Our data underscore the high allelic heterogeneity of CDA II, as the most of SEC23B variations are inherited as private mutations. In this mutation update, we also provided a tool to improve and facilitate the molecular diagnosis of CDA II by defining the frequency of mutations in each exon. Am. J.

    Anemias continue to present a challenge to the health care profession. Anemia is defined as a reduction in one or more of the RBC indices. Patients presenting with a mild form of anemia may be asymptomatic; however, in more serious cases the anemia can become life threatening. In many cases the clinical presentation also reflects the underlying cause. Anemia may be attributed to various causes, whereas autoimmune RBC destruction may be attributed to intrinsic and extrinsic factors. Laboratory tests are essential in facilitating early detection and differentiation of anemia. Published by Elsevier Inc.

    Hemoglobin concentrations slightly below the lower limit of normal are a common laboratory finding in the elderly, but scant evidence is available on the actual occurrence of mild anemia despite its potential effect on health. The objectives of this study were to estimate the prevalence and incidence of mild grade anemia and to assess the frequency of anemia types in the elderly. This was a prospective, population-based study in all residents 65 years or older in Biella, Italy. Blood test results were available for analysis from 8,744 elderly. Hemoglobin concentration decreased and mild anemia increased steadily with increasing age. Mild anemia (defined as a hemoglobin concentration of 10.0-11.9 g/dL in women and 10.0-12.9 g/dL in men) affected 11.8% of the elderly included in the analysis, while the estimated prevalence in the entire population was 11.1%. Before hemoglobin determination, most mildly anemic individuals perceived themselves as non-anemic. Chronic disease anemia, thalassemia trait, and renal insufficiency were the most frequent types of mild anemia. The underlying cause of mild anemia remained unexplained in 26.4% of the cases, almost one third of which might be accounted for by myelodysplastic syndromes. In a random sample of non-anemic elderly at baseline (n=529), after about 2 years, the annual incidence rate of mild anemia was 22.5 per 1000 person-years and increased with increasing age. The prevalence and incidence of mild anemia increase with age and mild anemia affects more than one out of ten elderly individuals. Unexplained anemia is common and may be due to myelodysplastic syndromes in some cases.

    The length of the chromosome ends, telomeres, is widely accepted as a biomarker of aging. However, the dynamic of the relationship between telomere length and hematopoietic parameters in the normal aging process, which is of particular interest with respect to age-related anemia, is not well understood. We have analyzed the relationship between relative leukocyte telomere length (rLTL) and several hematological parameters in the older group of the Berlin Aging Study II (BASE-II) participants. This paper also compares rLTL between both BASE-II age groups (22-37 and 60-83 years). Genomic DNA was extracted from peripheral blood leukocytes of BASE-II participants and used to determine rLTL by a quantitative PCR protocol. Standard methods were used to determine blood parameters, and the WHO criteria were used to identify anemic participants. Telomere length data were available for 444 younger participants (28.4 ± 3.1 years old; 52% women) and 1,460 older participants (68.2 ± 3.7 years old; 49.4% women). rLTL was significantly shorter in BASE-II participants of the older group (p = 3.7 × 10-12) and in women (p = 4.2 × 10-31). rLTL of older men exhibited a statistically significant, positive partial correlation with mean corpuscular hemoglobin (MCH; p = 0.012) and MCH concentration (p = 0.002). While these correlations were only observed in men, the rLTL of older women was negatively correlated with the number of thrombocytes (p = 0.015) in the same type of analysis. Among all older participants, 6% met the criteria to be categorized as 'anemic'; however, there was no association between anemia and rLTL. In the present study, we have detected isolated correlations between rLTL and hematological parameters; however, in all cases, rLTL explained only a small part of the variation of the analyzed parameters. In disagreement with some other studies showing similar data, we interpret the association between rLTL and some of the hematological parameters studied here to be

    The aim of this study was to characterize the frequency and causes of anemia in glycogen storage disease type I. Hematologic data and iron studies were available from 202 subjects (163 with glycogen storage disease Ia and 39 with glycogen storage disease Ib). Anemia was defined as hemoglobin concentrations less than the 5th percentile for age and gender; severe anemia was defined as presence of a hemoglobin glycogen storage disease Ia, 68/163 patients were anemic at their last follow-up. Preadolescent patients tended to have milder anemia secondary to iron deficiency, but anemia of chronic disease predominated in adults. Severe anemia was present in 8/163 patients, of whom 75% had hepatic adenomas. The anemia improved or resolved in all 10 subjects who underwent resection of liver lesions. Anemia was present in 72% of patients with glycogen storage disease Ib, and severe anemia occurred in 16/39 patients. Anemia in patients with glycogen storage disease Ib was associated with exacerbations of glycogen storage disease enterocolitis, and there was a significant correlation between C-reactive protein and hemoglobin levels (P = 0.036). Anemia is a common manifestation of both glycogen storage disease Ia and Ib, although the pathophysiology appears to be different between these conditions. Those with severe anemia and glycogen storage disease Ia likely have hepatic adenomas, whereas glycogen storage disease enterocolitis should be considered in those with glycogen storage disease Ib.

    Although chronic kidney disease-induced anemia is more prevalent in patients with diabetes mellitus (DM), anemia is a common finding prior to manifestation of kidney disease. In presence of some risk factors at the time of diagnosing DM, microvascular complications must be considered. The effect of anemia as a risk factor on progression of DM complications is still unclear. The aim of the study was to determine the prevalence of anemia and its association with microvascular complications in patients with type 2 DM. This cross-sectional study was performed in the outpatient endocrinology clinic at Baqiyatallah University of Medical Sciences Hospital, Tehran, Iran. Study was done from February 2011 to February 2012. Patients with type 2 DM without any obvious symptom or sign of anemia were included in study. A total of 93 patients (30.4%) had anemia including 46 (15.1%) with normochromic normocytic, 44 (14.4%) with hyperchromic microcytic, and 3 (1%) with hyperchromic macrocytic anemias. There was a positive correlation between duration of DM and anemia. Microvascular complications were more frequent with normocytic or microcytic anemias. Glomerular filtration rate (GFR) was higher in patients without anemia; moreover, nephropathy was less frequent among them. Among patients with anemia, 43% had GFR of more than 90 mL/min and 19.4% had normoalbuminuria. Neuropathy, nephropathy, and retinopathy had strong association with anemia (odds ratio of 1.99, 1.7, and 1.5, respectively). Anemia is a common complication of DM and is associated with duration of disease and microvascular complications.

  16. Iron Deficiency and Other Types of Anemia in Infants and Children.

    Anemia, defined as a hemoglobin level two standard deviations below the mean for age, is prevalent in infants and children worldwide. The evaluation of a child with anemia should begin with a thorough history and risk assessment. Characterizing the anemia as microcytic, normocytic, or macrocytic based on the mean corpuscular volume will aid in the workup and management. Microcytic anemia due to iron deficiency is the most common type of anemia in children. The American Academy of Pediatrics and the World Health Organization recommend routine screening for anemia at 12 months of age; the U.S. Preventive Services Task Force found insufficient evidence to assess the benefits vs. harms of screening. Iron deficiency anemia, which can be associated with cognitive issues, is prevented and treated with iron supplements or increased intake of dietary iron. The U.S. Preventive Services Task Force found insufficient evidence to recommend screening or treating pregnant women for iron deficiency anemia to improve maternal or neonatal outcomes. Delayed cord clamping can improve iron status in infancy, especially for at-risk populations, such as those who are preterm or small for gestational age. Normocytic anemia may be caused by congenital membranopathies, hemoglobinopathies, enzymopathies, metabolic defects, and immune-mediated destruction. An initial reticulocyte count is needed to determine bone marrow function. Macrocytic anemia, which is uncommon in children, warrants subsequent evaluation for vitamin B12 and folate deficiencies, hypothyroidism, hepatic disease, and bone marrow disorders.

    To investigate the relationship among anemia, physiological serum bilirubin levels, and cardiovascular autonomic neuropathy (CAN) in subjects with type 2 diabetes. In total, 2230 subjects with type 2 diabetes were evaluated in this cross-sectional study. CAN was diagnosed with a cardiovascular reflex test. The prevalence of anemia was greater in subjects with CAN. In multivariable analysis, the relationship between anemia and CAN remained statistically significant after adjusting for the risk factors (odds ratio [OR] 1.39; 95% confidence interval [CI] 1.07-1.80, P = .015). Additional adjustment for serum bilirubin concentrations abolished this relationship (OR 1.20, 95% CI 0.91-1.58, P = .189). Anemia is positively associated with the prevalence of CAN in subjects with type 2 diabetes. In addition, our results suggest that the putative increased CAN risk associated with anemia might be mediated by a correlated decrease in serum bilirubin levels.

    To classify the different types of anemia among moderately to severely disabled women living in the community and examine the relationship between types of anemia and mortality. We studied anemia in 688 women, >or=65 years, in the Women's Health and Aging Study I, a population based study of moderately to severely disabled older women living in the community in Baltimore, Maryland. Anemia was defined by World Health Organization criteria. Causes of anemia were classified as due to nutritional deficiencies (iron, folate, and B12 deficiencies), anemia of chronic inflammation, anemia with renal disease, and unexplained anemia. 147 of 688 (21.4%) women were anemic (hemoglobin anemia due to nutritional causes, 45 (30.6%) had anemia due to chronic inflammation, 29 (19.7%) had anemia and renal disease, and 51 (34.7%) had unexplained anemia. The proportions of those who died over five years among non-anemic women and women with anemia due to nutritional causes, chronic inflammation, renal disease, and unexplained anemia were 26.1%, 18.2%, 38.6%, 64.3%, and 33.3%, respectively (panemia and renal disease (HR 1.99, 95% CI 1.18-3.35, p=0.009) and anemia of chronic inflammation (HR 1.69, 95% CI 1.00-2.84, p=0.05) had higher risk of death. Anemia is common among moderately to severely disabled older women living in the community, and about one-third of the anemia is unexplained. Anemia with renal disease and anemia of chronic inflammation are associated with a higher mortality.

    Childhood anemia is a major global health problem resulting from multiple causes. Iron supplementation addresses iron deficiency anemia but is undesirable for other types of anemia and may exacerbate infections. The peptide hormone hepcidin governs iron absorption; hepcidin transcription is mediated by iron, inflammation, and erythropoietic signals. However, the behavior of hepcidin in populations where anemia is prevalent is not well established. We show that hepcidin measurements in 1313 African children from The Gambia and Tanzania (samples taken in 2001 and 2008, respectively) could be used to identify iron deficiency anemia. A retrospective secondary analysis of published data from 25 Gambian children with either postmalarial or nonmalarial anemia demonstrated that hepcidin measurements identified individuals who incorporated >20% oral iron into their erythrocytes. Modeling showed that this sensitivity of hepcidin expression at the population level could potentially enable simple groupings of individuals with anemia into iron-responsive and non-iron-responsive subtypes and hence could guide iron supplementation for those who would most benefit.

    Plasmodium vivax has been reported to cause severe malaria, and one of the main resulting complications is anemia. Considering that P. vivax infects only young erythrocytes, anemia has been associated with the destruction of infected and non-infected erythrocytes. However, few studies have focused on understanding the relationship between the pathogenesis of P. vivax malaria and human genetic polymorphisms. Although ABO groups seem to influence the outcome of Plasmodium falciparum malaria, the association between P. vivax and ABO blood groups has been minimally investigated. Thus, we investigate the correlation between ABO blood groups and anemia induced by P. vivax infection. Five single nucleotide polymorphisms at the ABO gene were genotyped by PCR-RFLP and Real-Time PCR in P. vivax-infected subjects. The ABO blood types were associated with the hematological data of the patients. Our main finding was that type O infected-individuals showed lower levels of hemoglobin and hematocrit compared to type A-infected individuals. The correlation between ABO blood groups and hemoglobin levels remained significant when a multiple linear regression was applied with the possible confounding effects of clinical-epidemiologic variables taken into account. The finding that type O individuals have a higher frequency of anemia is a first step to understand the mechanisms involved in malaria anemia, which could be associated to increased destruction of type O erythrocytes.

    There is much interest in the tissue of origin of circulating DNA in plasma. Data generated using DNA methylation markers have suggested that hematopoietic cells of white cell lineages are important contributors to the circulating DNA pool. However, it is not known whether cells of the erythroid lineage would also release DNA into the plasma. Using high-resolution methylation profiles of erythroblasts and other tissue types, 3 genomic loci were found to be hypomethylated in erythroblasts but hypermethylated in other cell types. We developed digital PCR assays for measuring erythroid DNA using the differentially methylated region for each locus. Based on the methylation marker in the ferrochelatase gene, erythroid DNA represented a median of 30.1% of the plasma DNA of healthy subjects. In subjects with anemia of different etiologies, quantitative analysis of circulating erythroid DNA could reflect the erythropoietic activity in the bone marrow. For patients with reduced erythropoietic activity, as exemplified by aplastic anemia, the percentage of circulating erythroid DNA was decreased. For patients with increased but ineffective erythropoiesis, as exemplified by β-thalassemia major, the percentage was increased. In addition, the plasma concentration of erythroid DNA was found to correlate with treatment response in aplastic anemia and iron deficiency anemia. Plasma DNA analysis using digital PCR assays targeting the other 2 differentially methylated regions showed similar findings. Erythroid DNA is a hitherto unrecognized major component of the circulating DNA pool and is a noninvasive biomarker for differential diagnosis and monitoring of anemia. © 2017 American Association for Clinical Chemistry.

    The prevalence of anemia in inflammatory bowel disease (IBD) has been broadly described. The recurrence, type and burden of anemia remain unenlightened. The primary objective was to describe this. The secondary objective was to evaluate the implementation of European guidelines. This longitudinal follow-up study included 300 IBD outpatients from six centers in Scandinavia. Patients were enrolled in a research cohort, in which each center included 5% of their IBD cohort. The study was prospectively planned, while data were retrospectively collected. The burden of anemia was calculated as number of months with anemia. A Markov model was used to calculate the probabilities of transitioning between stages. The European guidelines were used as the standard for anemia management. Anemia affected > 50% of IBD outpatients during the 2-year observation period. Totally, 20% of the total observation time was spent in anemia. Over the 7200 months of observation, anemia was found in 1410 months. The most frequent type was combined anemia (63%). Combined anemia covers both anemia of chronic disease (ACD) and iron-deficiency anemia (IDA). Pure ACD was present in 21% of burden time, while pure IDA was present in 16% of burden time. The European guidelines have mainly been implemented. Anemia affected a majority of the IBD outpatients. One in five months, the patients were anemic. Anemia related to inflammation dominated the different types of anemia. Pure IDA was found in for 16%. These findings, despite a fair implementation of guidelines.

    Congenital dyserythropoietic anemias are rare blood disorders characterized by congenital anemia and a wide range of morphological and functional abnormalities of erythroid precursors. To analyze the relative frequency of both light microscopic (LM) and electron microscopic (EM) morphological features of erythroblasts in a large group of patients with molecular proven congenital dyserythropoietic anemia type I (CDAI). We retrospectively evaluated the LM and EM of bone marrow (BM) erythroblasts in 35 patients with CDAI. Thirty-four patients carried the CDAN1 Arg1042Trp founder mutation and one the p.Pro1130Leu mutation. BM slides of 24 patients were available for LM examination. EM studies were performed in all 35 patients. On LM, marked erythroid hyperplasia, binuclear erythroblasts, and various non-specific dyserythropoietic features were documented in every case; internuclear chromatin bridges were detected in 19 patients (79%). In all, EM of erythroblasts revealed a spongy appearance of heterochromatin, a widening of nuclear pores, and invagination of cytoplasm into the nuclear region. EM studies revealed high morphological frequency of specific ultrastructural changes in erythroblasts which facilitate prompt diagnosis of CDAI. Due to low specificity of BM LM findings, when BM EM is unavailable diagnostic approach should also include other inherited anemias. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Anemia is a risk factor for adverse events after cardiac operations. We evaluated the incremental value of preoperative anemia over the European System for Cardiac Operative Risk Evaluation (EuroSCORE) II to predict hospital death after cardiac operations. Data for 4,594 consecutive adults (1,548 women [33.7%]), aged 67 ± 11 years, who underwent cardiac operations from January 2011 to July 2013 were extracted from the Regional Cardiac Surgery Registry of Puglia. The last preoperative hemoglobin value was used, according to World Health Organization criteria, to classify anemia as mild (hemoglobin 11.0 to 12.9 g/dL in men and 11.0 to 11.9 g/dL in women) in 1,021 patients (22.2%) and as moderate to severe (hemoglobin anemia, with model discrimination quantified by C statistic and risk classification by the use of net reclassification improvement (NRI). Overall expected and observed mortality rates were 4.4% and 5.9%. Anemia was significantly associated with a mortality rate of 3.4% in patients without anemia, 7.7% in mild anemia, and 15.7% in moderate to severe anemia (p anemia was analyzed with EuroSCORE II, the model improved in discrimination (C statistic = 0.852 vs 0.860; p = 0.007) and reclassification (category free-NRI, 0.592; p anemia has strong association with operative death in cardiac surgical patients. Anemia provides significant incremental value over the EuroSCORE II and should be considered for assessment of cardiac surgical risk. Copyright © 2014 The Society of Thoracic Surgeons.

    Introduction Anemia is a significant public health problem among children and women globally. It is one of the most common causes of deaths among children admitted to hospitals in sub-Saharan Africa. Case fatality rates of 6 percent to 18 percent have been reported even in facilities that have blood transfusions services. The purpose of this study was to evaluate the magnitude, severity, and morphological types of anemia among hospitalized children under five years of age in the southern part of Tanzania. Methods A cross-sectional, hospital-based, retrospective analysis was conducted in February 2016 using hospital records of 303 children aged 0-59 months admitted to St. Benedict Ndanda Referral Hospital, Mtwara, Tanzania between 1 July 2015 and 31 December 2015.  Results The mean hemoglobin (Hb) level of the study population was 7.87 ± 2.84 g/dL, the median was 8.00g/dL, the interquartile range (IQR) was 4.40g/dL, and the prevalence of anemia was 83.17 percent. The magnitude of mild, moderate, and severe anemia was 9.13 percent, 44.84 percent, and 46.03 percent, respectively, and about half of all anemic children had normocytic anemia. Conclusion Severe anemia is a common health problem among hospitalized children under five years of age in the study area. We recommend screening all admitted children under the age of five for anemia, and clinicians should pay attention to and put more emphasis on intervention strategies for anemia when treating children admitted for other diseases.

    Objective Retinopathy is an established microvascular complication of type 2 diabetes mellitus (T2DM), but its independent relationship with macrovascular and other microvascular complications is less well defined across the spectrum of kidney disease in T2DM. We examined the prognostic value of retinopathy in assessing the risk of developing end-stage renal disease (ESRD), cardiovascular morbidity or death among patients in the Trial to Reduce cardiovascular Events with Aranesp Therapy (TREAT). Design TREAT enrolled 4038 patients with T2DM, chronic kidney disease (CKD) and moderate anemia. Patients were grouped by baseline history of retinopathy. Proportional hazards regression models were utilized to assess the association between retinopathy and subsequent ESRD, cardiovascular morbidity or death over an average of 2.4 years. Results Although younger, the 1895 (47%) patients with retinopathy had longer duration of diabetes, lower estimated glomerular filtration rate, more proteinuria, and more microvascular complications. In univariate analysis, retinopathy was associated with a higher rate of ESRD, but not with cardiovascular events or mortality. After adjustment, retinopathy was no longer statistically significant for the prediction of ESRD or any clinical endpoint. Conclusions In a large cohort of patients with T2DM, CKD, and anemia, retinopathy was common but not independently associated with a higher risk of renal or cardiovascular morbidity or death.

    This work aimed to highlight a challenging asymptomatic problem which is early detection of hearing impairment in toddlers with protein energy malnutrition (PEM) as a neuro-cognitive effect of PEM on developing brain in relation to hemoglobin level. 100 toddlers, aged 6-24 months, fifty with moderate/severe PEM and fifty healthy children, were included in study. Both TEOAEs and ABR testing were used to assess auditory function. Study reported an association between malnutrition and hearing impairment, 26% of cases had conductive deafness secondary to otitis media with effusion using tympanometry; 84.6% showed type B and 15.4% type C which may suggest developing or resolving otitis media. Their ABR showed 46% mild and 53% moderate impairment. 32% of PEM cases had sensory neural hearing loss and with type (A) tympanometry. Those were assessed using ABR; 58% had mild, 34% moderate and 8% profound impairment. 10% of PEM cases had mixed hearing loss with 50% type B and 50% type C tympanometry and their ABR showed moderate to profound impairment. TEOAEs latencies at different frequencies correlate negatively with hemoglobin level. Toddlers with moderate/severe PEM had hearing impairments of different types and degrees. Neuro-physiological methods could be early and safe detectors of auditory disorders especially in high-risk toddlers. Anemia increases risk for auditory dysfunction.

  9. DO GIANT PLANETS SURVIVE TYPE II MIGRATION?

    International Nuclear Information System (INIS)

    Hasegawa, Yasuhiro; Ida, Shigeru

    2013-01-01

    Planetary migration is one of the most serious problems to systematically understand the observations of exoplanets. We clarify that the theoretically predicted type II, migration (like type I migration) is too fast, by developing detailed analytical arguments in which the timescale of type II migration is compared with the disk lifetime. In the disk-dominated regime, the type II migration timescale is characterized by a local viscous diffusion timescale, while the disk lifetime is characterized by a global diffusion timescale that is much longer than the local one. Even in the planet-dominated regime where the inertia of the planet mass reduces the migration speed, the timescale is still shorter than the disk lifetime except in the final disk evolution stage where the total disk mass decays below the planet mass. This suggests that most giant planets plunge into the central stars within the disk lifetime, and it contradicts the exoplanet observations that gas giants are piled up at r ∼> 1 AU. We examine additional processes that may arise in protoplanetary disks: dead zones, photoevaporation of gas, and gas flow across a gap formed by a type II migrator. Although they make the type II migration timescale closer to the disk lifetime, we show that none of them can act as an effective barrier for rapid type II migration with the current knowledge of these processes. We point out that gas flow across a gap and the fraction of the flow accreted onto the planets are uncertain and they may have the potential to solve the problem. Much more detailed investigation for each process may be needed to explain the observed distribution of gas giants in extrasolar planetary systems

    To compare the differences between hematopoietic reconstitution and longterm prognosis of patients with severe aplastic anemia (SAA) after HLA- matched sibling donor hematopoietic stem cell transplantation(MSD-HSCT), Haploidentical HSCT(Haplo-HSCT), unrelated donor allogeneic HSCT(UD-HSCT)and umbilical cord blood HSCT(UCB-HSCT). In this retrospective study, 63 patients with SAA who received HSCT in the First Affiliated Hospital of Soochow University between May 2008 and December 2013 were enrolled. The subjects were divided into 4 groups according to the transplantation types. The hematopoietic reconstitution, the incidence of acute graft-versushost disease(aGVHD)and 5- year survival rate after transplantation were compared. All 53 subjects who received MSD-HSCT, Haplo-HSCT and UD-HSCT achieved hematopoietic reconstitution. Of them, the recovery of neutrophil and platelet were not significantly different(P0.05). MSD-HSCT, Haplo-HSCT and UD-HSCT had no statistically significance in terms of hematopoietic reconstitution or prognosis. Although hematopoietic reconstitution of UCB-HSCT was lower than other transplantation types, but no significant difference in overall prognosis. So if HLA-matched sibling donor is not available, SAA patients can choose Haplo- HSCT, UD - HSCT or UCB- HSCT with comparable efficacy to MSD- HSCT, as an alternative therapy.

    We present photometry and spectroscopy of nine Type II-P/L supernovae (SNe) with redshifts in the 0.045 ≲ z ≲ 0.335 range, with a view to re-examining their utility as distance indicators. Specifically, we apply the expanding photosphere method (EPM) and the standardized candle method (SCM) to each target, and find that both methods yield distances that are in reasonable agreement with each other. The current record-holder for the highest-redshift spectroscopically confirmed supernova (SN) II-P is PS1-13bni (z = 0.335-0.012+0.009), and illustrates the promise of Type II SNe as cosmological tools. We updated existing EPM and SCM Hubble diagrams by adding our sample to those previously published. Within the context of Type II SN distance measuring techniques, we investigated two related questions. First, we explored the possibility of utilising spectral lines other than the traditionally used Fe IIλ5169 to infer the photospheric velocity of SN ejecta. Using local well-observed objects, we derive an epoch-dependent relation between the strong Balmer line and Fe IIλ5169 velocities that is applicable 30 to 40 days post-explosion. Motivated in part by the continuum of key observables such as rise time and decline rates exhibited from II-P to II-L SNe, we assessed the possibility of using Hubble-flow Type II-L SNe as distance indicators. These yield similar distances as the Type II-P SNe. Although these initial results are encouraging, a significantly larger sample of SNe II-L would be required to draw definitive conclusions.

    2014-12-01

    Full Text Available We study the possibility of generating tiny neutrino mass through a combination of type I and type II seesaw mechanism within the framework of an abelian extension of standard model. The model also provides a naturally stable dark matter candidate in terms of the lightest neutral component of a scalar doublet. We compute the relic abundance of such a dark matter candidate and also point out how the strength of type II seesaw term can affect the relic abundance of dark matter. Such a model which connects neutrino mass and dark matter abundance has the potential of being verified or ruled out in the ongoing neutrino, dark matter, as well as accelerator experiments.

    Anemia is common in diabetic patients and increases morbidity and mortality, but its burden has been less well characterized in sub-Saharan Africans. We determined the prevalence of anemia and investigated the related factors, with a particular focus on the role of declining renal function, in type 2 diabetic patients attending a tertiary health care institution in Cameroon. Hemoglobin (Hb) levels were measured in a consecutive sample of patients with type 2 diabetes, who reported for annual review at the outpatient section of the Douala General Hospital in 2013. Patients were classified as anemic according to the World Health Organisation criteria (Hb Diet in Renal Disease Study Group formula. Determinants of Hb concentration and anemia were investigated using multivariable logistic regressions. A total of 636 patients were examined including 263 (prevalence rate 41.4 %) who had anemia. The prevalence of anemia increased significantly with deteriorating kidney function, although up to 31.9 % of patients with normal kidney function had anemia. Compared with their non-anemic counterparts, anemic diabetic patients were older, had longer duration of diabetes, lower eGFR, higher prevalence of proteinuria and diabetic retinopathy (all p diabetic patients attending referral institutions in Cameroon, including among those without chronic kidney disease. Routine screening for anemia in all diabetic patients may aid early identification and correction as appropriate.

    To study the clinical manifestations, outcomes, and survival of warm-type autoimmune hemolytic anemia (AIHA) patients. This study was a retrospective single-center study from 2002 to 2013. Clinical data of AIHA patients were reviewed and analyzed. One hundred and one patients were included, of whom 77% were female with a median age of 43 years. Primary AIHA was found in 61% of the patients. The secondary causes were systemic lupus erythematosus (SLE) (64%), solid malignancies (13%), lymphomas (10%), drugs (8%), and infections (5%). Most patients (96%) responded to steroids, which were not different between primary and secondary AIHA. Second-line treatments were required in 33 patients (33%). The indications were steroid dependence (58%), relapse (30%), and others (12%). The most common second-line treatment was cyclophosphamide (52%). The response rate for second-line treatments was 93%. Relapse occurred in 50 patients (50%) in which 58% occurred more than 3 years after diagnosis. The SLE patients relapsed and received second-line therapy more than the non-SLE group (P < 0.001). At the median 53-month follow-up, the overall survival (OS) was 84%. The independent risk factors for OS were age more than 50 years and malignancy. Sepsis was the most common cause of death. AIHA has a good prognosis and long-term survival especially in young patients without malignancy. Most patients have responded initially to steroids and have a high response rate to second-line therapy. Carefully adjusted and rapid taper of immunosuppressant is necessary to avoid sepsis complications.

    The vast majority of Type II supernovae (SNeII) are produced by red supergiants, but SN 1987A revealed that blue supergiants (BSGs) can produce members of this class as well, albeit with some peculiar properties. This best-studied event revolutionized our understanding of SNe and linking it to the bulk of Type II events is essential. We present here the optical photometry and spectroscopy gathered for SN 2000cb, which is clearly not a standard SNII and yet is not a SN 1987A analogue. The light curve of SN 2000cb is reminiscent of that of SN 1987A in shape, with a slow rise to a late optical peak, but on substantially different time-scales. Spectroscopically, SN 2000cb resembles a normal SNII, but with ejecta velocities that far exceed those measured for SN 1987A or normal SNeII, above 18 000 km s-1 for Hα at early times. The red colours, high velocities, late photometric peak and our modelling of this object all point towards a scenario involving the high-energy explosion of a small-radius star, most likely a BSG, producing 0.1 M⊙ of 56Ni. Adding a similar object to the sample, SN 2005ci, we derive a rate of ˜2 per cent of the core-collapse rate for this loosely defined class of BSG explosions.

    We suggest two types of extension of the standard model, which are the so-called next to new minimal standard model type-II and -III. They can achieve gauge coupling unification as well as suitable dark matter abundance, small neutrino masses, baryon asymmetry of the universe, inflation, and dark energy. The gauge coupling unification can be realized by introducing two or three extra new fields, and they could explain charge quantization. We also show that there are regions in which the vacuum stability, coupling perturbativity, and correct dark matter abundance can be realized with current experimental data at the same time. (orig.)

    Many processes lead to anemia. This review covers anemias that are less commonly encountered in the United States. These anemias include hemoglobin defects like thalassemia, bone marrow failure syndromes like aplastic anemia and pure red cell aplasia, and hemolytic processes such as paroxysmal nocturnal hemoglobinuria. The pathogenesis, diagnostic workup, and treatment of these rare anemias are reviewed. Copyright © 2016 Elsevier Inc. All rights reserved.

    The prevalent notion about maxillary central incisor with normal external morphology is a tooth with single root and root canal. A case in which all four maxillary incisors were having Type II canal configurations (Vertucci's classification) is reported, in addition, the lateral incisors revealed dens invaginatus with a Type I pattern as suggested by Ohler's classification and a large periapical lesion was seen in relation to the right lateral incisor. The diagnosis was confirmed with the aid of spiral computed tomography (CT) and canals obturated. Nonsurgical healing of the lesion was assessed by reviewing the case at prefixed intervals of time.

    Full Text Available Iron deficiency anemia (IDA is the most frequent form of anemia in pregnant women. Folic acid, vitamin B12 deficiency, and hemoglobinopathies are other causes of anemia in pregnancy. Finding the underlying cause are crucial to the management of the anemia. Anemia is defined as hemoglobin of <11 g/dl in the first and third trimester and <10.5 g/dl in second trimester. According to the literature, anemia, particularly severe anemia (Hb<7g/dl is associated with increased risk of maternal and perinatal mortality and morbidity, and long term adverse effects in the newborn. The association of hemoglobin levels to perinatal outcome has been shown to be U shaped with both high and low hemoglobin levels being associated adverse perinatal outcome such as low birth weight, increased stillbirths. Anemia in pregnancy is a major public health problem. Ideally a woman should have adequate iron stores when she conceives, in order meet to additional requirements of pregnancy. This review focuses on the occurrence, types, maternal and perinatal outcomes, prevention and treatment of anemia during pregnancy. [Archives Medical Review Journal 2013; 22(3.000: 300-316

    This study was designed to compare the effects of the anti-human T lymphocyte globulin (Fresenius, ATG-F)and rabbit anti-human thymocyte immunoglobulin (Genzyme, R-ATG)in the treatment of childhood aplastic anemia (AA) and their effects. A total of 59 children with aplastic anemia were analyzed in the present study, including 34 cases of severe aplastic anemia (SAA), 12 cases of very severe aplastic anemia (VSAA) and 13 cases of transfusion-dependent non-severe aplastic anemia (NSAA). While receiving immunosuppressive therapy (IST), 30 and 29 patients, with long-term oral supplement with cyclosporin A (CSA), androgen and Chinese traditional medicines, were treated with ATG-F and R-ATG, respectively. When it was necessary, some supportive cares such as component transfusion and infection control were also employed. Absolute counts of peripheral blood lymphocyte (ALC) at various time points were dynamically detected after ATG therapy. According to the International Aplastic Anemia Treatment and Effect standards. There were no statistically significant differences in the overall response rate (67%(20/30)vs. 69%(20/29), χ(2)=0.036, P=0.676) and the survival rate (87%(26/30)vs. 83%(24/29), χ(2)=0.173, P=0.676) between the ATG-F and R-ATG groups. There were significant and long-term ALC decrease after ATG therapy, the rate of ALC decrease in ATG-F and R-ATG group, the ALC only recovered to 47.8% (ATG-F group) and 47.4% (R-ATG group) of the pre-treatment level respectively. ATG-F 5 mg/(kg·d) and R-ATG 3.75 mg/(kg·d)could achieve similar effects in the treatment of childhood AA, through similar significant clearance of T cells. Therefore, all of these suggest that ATG-F and R-ATG might serve as the drugs of front-line choice for IST in childhood AA patients who do not have an available human leukocyte antigen identical related donor.

If the patient has a severe, extended, or treatment-recalcitrant course of herpes zoster, this must be a red flag to search for underlying pathologies. Here, we report about a 64-year-old male patient with diabetes, who came to our emergency department because of general malaise, fever, chills, and a pronounced nuchal and facial swelling on the left side. Based on herpetiform-grouped vesicles and yellowish crusts, an impetiginized facial herpes zoster was diagnosed, and combined antiviral and antibiotic treatment was initiated. He was HIV negative. Despite intensified treatment, his situation worsened. We observed blasts in peripheral blood, but bone marrow biopsy was initially denied. Some days later after deterioration of his disease, he accepted further diagnostics. A myelodysplastic syndrome with blast excess (refractory anemia and blast excess II, RAEB II could be confirmed. The following translocations were detected: t(2;12(p13; q13 and t(6;9(p22;q34. REAB II has an unfortunate prognosis. Cytoreductive treatment was initiated by the hemato-oncologist.

  6. Spectral modeling of Type II SNe

    The red supergiant phase represents the final stage of evolution in the life of moderate mass (8-25Msun) massive stars. Hidden from view, the core changes considerably its structure, progressing through the advanced stages of nuclear burning, and eventually becomes degenerate. Upon reaching the Chandrasekhar mass, this Fe or ONeMg core collapses, leading to the formation of a proto neutron star. A type II supernova results if the shock that forms at core bounce, eventually wins over the envelope accretion and reaches the progenitor surface.The electromagnetic display of such core-collapse SNe starts with this shock breakout, and persists for months as the ejecta releases the energy deposited initially by the shock or continuously through radioactive decay. Over a timescale of weeks to months, the originally optically-thick ejecta thins out and turns nebular. SN radiation contains a wealth of information about the explosion physics (energy, explosive nucleosynthesis), the progenitor properties (structure and composition). Polarised radiation also offers signatures that can help constrain the morphology of the ejecta.In this talk, I will review the current status of type II SN spectral modelling, and emphasise that a proper solution requires a time dependent treatment of the radiative transfer problem. I will discuss the wealth of information that can be gleaned from spectra as well as light curves, from both the early times (photospheric phase) and late times (nebular phase). I will discuss the diversity of Type SNe properties and how they are related to the diversity of red supergiant stars from which they originate.SN radiation offers an alternate means of constraining the properties of red-supergiant stars. To wrap up, I will illustrate how SNe II-P can also be used as probes, for example to constrain the metallicity of their environment.

    We aim to investigate erythropoietin (EPO) response to anemia and its association with autonomic neuropathy in type 2 diabetic patients without advanced renal failure. A cross-sectional study was conducted on 211 type 2 diabetes mellitus patients without advanced renal failure [estimated glomerular filtration rate (eGFR) >40 ml/min/1.73 m(2)]. The response of EPO to anemia of type 2 diabetic patients without advanced renal failure was compared with those of nondiabetic control subjects. Autonomic nerve function was assessed using three cardiovascular tests (deep breathing, the Valsalva maneuver, and lying-to-standing). The results of each test were scored as 0 if normal, 1 if borderline, and 2 if abnormal. Autonomic neuropathy was diagnosed when a total score of the tests was 2 or more. Fifty-eight patients were anemic; compared with nonanemic patients, they had a longer duration of diabetes (16.69+/-10.11 vs. 10.67+/-8.41 years, Pdiabetic patients and nondiabetic control subjects (-0.0085 vs. -0.255, P=.008). Multiple linear regression analysis revealed that cardiovascular autonomic neuropathy score was independently related to Hb (Pdiabetic patients without advanced renal failure.

    Type II are the most common class of the ``core collapse'' supernova, involving the destruction of a high mass star (> 8M⊙). Their death is a result of a self-gravitational force becoming unbalanced as fusion ceases in the stellar core, leading to the collapse of the core to form a neutron star. The propagation of the shock ignites fusion into heavier elements as it progress through the star. This process is the origin of most elements present in the universe. In recent years, the complex nature of the explosion (its hydrodynamics, transport of energy, and the created isotopes) have been studied with increasing physical fidelity. Detailed nucleosynthesis from models of these core collapse supernovae is calculated in a post-processing step, using thermodynamic trajectories. My work on the project has been to develop the tools to visualize the results of post-processing calculations in the 2D grid. National Science Foundation (NSF).

    Herein is described a case of immunoglobulin M (IgM) warm autoimmune hemolytic anemia (AIHA) in a child who consequently died within 3 days of clinical onset. A previously healthy 11-year-old boy presented with fever, anemia, jaundice, and deteriorating consciousness. On direct agglutination test against group O red blood cells, agglutination was seen even at 37°C in saline, which was abolished on dithiothreitol treatment of the serum, indicating that the responsible autoantibody was IgM and had a warm-reactive capacity. A diagnosis of IgM warm AIHA was therefore made. Hemagglutination in the visceral capillaries was considered as the direct cause of organ dysfunction. The patient died due to respiratory failure. IgM warm AIHA is a very severe condition that is difficult to reverse in an advanced state. Both prompt, definite diagnosis and intervention are therefore vital to prevent severe multi-organ dysfunction in cases of IgM warm AIHA. © 2016 Japan Pediatric Society.

    The effect of anemia in advanced chronic kidney disease (CKD) on morbidity and mortality is known. The aim of the present study was to assess the effect of mild anemia on hospitalization and 1-year all-cause mortality in type 2 diabetes mellitus (T2DM) patients with Stage 1 and 2 CKD. Hospitalized T2DM patients (n = 307) with a glomerular filtration rate ≥ 60 mL/min per 1.73 m(2) and urinary albumin excretion > 30 mg/24 h (Stage 1 and 2 CKD) were enrolled in the study and divided into two groups based on hemoglobin (Hb) concentrations: those with (mean [ ± SD] Hb 10.7 ± 0.7 g/dL) and without (mean Hb 13.3 ± 1.28 g/dL) anemia. There was no significant difference between patients with and without anemia in terms of age, gender, body mass index, HbA1c, and cardiovascular diseases. The mean length of hospitalization of the 130 anemic and 177 non-anemic patients was 4.3 ± 3.5 and 3.5 ± 1.9 days, respectively (P anemia (9.2% vs 1.7%, respectively; P = 0.002). After adjusting for confounding variables, multivariate Cox regression analysis revealed that mild anemia was significantly associated with 1-year all-cause mortality (hazard ratio 2.15, 95% confidence interval 1.92-2.54; P = 0.033). Mild anemia may increase the length of hospitalization and was associated with 1-year all-cause mortality among hospitalized T2DM patients with Stage 1 and 2 CKD. © 2015 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

    Full Text Available Type I ovarian tumors, where precursor lesions in the ovary have clearly been described, include endometrioid, clear cell, mucinous, low grade serous, and transitional cell carcinomas, while type II tumors, where such lesions have not been described clearly and tumors may develop de novo from the tubal and/or ovarian surface epithelium, comprise high grade serous carcinomas, undifferentiated carcinomas, and carcinosarcomas. The carcinogenesis of endometrioid and clear cell carcinoma (CCC arising from endometriotic cysts is significantly influenced by the free iron concentration, which is associated with cancer development through the induction of persistent oxidative stress. A subset of mucinous carcinomas develop in association with ovarian teratomas; however, the majority of these tumors do not harbor any teratomatous component. Other theories of their origin include mucinous metaplasia of surface epithelial inclusions, endometriosis, and Brenner tumors. Low grade serous carcinomas are thought to evolve in a stepwise fashion from benign serous cystadenoma to a serous borderline tumor (SBT. With regard to high grade serous carcinoma, the serous tubal intraepithelial carcinomas (STICs of the junction of the fallopian tube epithelium with the mesothelium of the tubal serosa, termed the “tubal peritoneal junction” (TPJ, undergo malignant transformation due to their location, and metastasize to the nearby ovary and surrounding pelvic peritoneum. Other theories of their origin include the ovarian hilum cells.

    Multiterminal transport measurements on YBa 2 Cu 2 O 7 crystals in the vortex liquid regime have shown nonlocal conductivity on length scales up to 50 microns. Motivated by these results we explore the wave vector (k) dependence of the dc conductivity tensor, σ μν (k), in the Meissner, vortex lattice, and disordered phases of a type-II superconductor. Our results are based on time-dependent Ginzburg-Landau (TDGL) theory and on phenomenological arguments. We find four qualitatively different types of behavior. First, in the Meissner phase, the conductivity is infinite at k=0 and is a continuous function of k, monotonically decreasing with increasing k. Second, in the vortex-lattice phase, in the absence of pinning, the conductivity is finite (due to flux flow) at k=0; it is discontinuous there and remains qualitatively like the Meissner phase for k>0. Third, in the vortex liquid regime in a magnetic field and at low temperature, the conductivity is finite, smooth and nonmonotonic, first increasing with k at small k and then decreasing at larger k. This third behavior is expected to apply at temperatures just above the melting transition of the vortex lattice, where the vortex liquid shows strong short-range order and a large viscosity. Finally, at higher temperatures in the disordered phase, the conductivity is finite, smooth and again monotonically decreasing with k. This last, monotonic behavior applies in zero magnetic field for the entire disordered phase, i.e., at all temperatures above T c , while in a field the nonmonotonic behavior may occur in a low-temperature portion of the disordered phase

    2012-05-01

    There have been several large-scale epidemiologic studies, including the National Health and Nutrition Examination Survey III (NHANES III), which have described the prevalence and impact of anemia in the elderly. The information derived has been critically important. However, given the large number of patients surveyed, these reports necessarily relied substantially on the laboratory-based screening evaluations. There are now two recent reports describing the cause of anemia in elderly outpatients, and although the numbers are smaller than the large scale surveys, they constitute comprehensive hematologic evaluations with therapeutic interventions and clinical follow-up. The purpose of this review is to compare these different analyses. There are distinct differences and similarities in the two types of studies, which are derived from patients seen in hematology clinics. Despite comprehensive hematologic evaluation, the puzzling entity of unexplained anemia of the elderly is confirmed and found to account for 30-46% of patients. NHANES III classified iron-deficiency anemia with other nutritional anemias, a classification that might be correct in the developing third world, but in North America and Western Europe, iron deficiency is more often caused by blood loss and the cause must be sought and dealt with. The myelodysplastic syndromes are an important cause of anemia in the elderly, with a prevalence of at least 4%. Large-scale screening studies of anemia in the elderly are of great importance, and when complemented by comprehensive hematologic evaluations, provide a more accurate picture of the clinical situation.

    The recent proposal of the type-II Weyl semimetal state has attracted significant interest. In this Letter, we propose the concept of the three-dimensional type-II Dirac fermion and theoretically identify this new symmetry-protected topological state in the large family of transition-metal icosagenides, M A3 (M =V , Nb, Ta; A =Al , Ga, In). We show that the VAl3 family features a pair of strongly Lorentz-violating type-II Dirac nodes and that each Dirac node can be split into four type-II Weyl nodes with chiral charge ±1 via symmetry breaking. Furthermore, we predict that the Landau level spectrum arising from the type-II Dirac fermions in VAl3 is distinct from that of known Dirac or Weyl semimetals. We also demonstrate a topological phase transition from a type-II Dirac semimetal to a quadratic Weyl semimetal or a topological crystalline insulator via crystalline distortions.

    It has recently been proposed that certain nonsupersymmetric type II orbifolds have vanishing perturbative contributions to the cosmological constant. We show that techniques of Sen and Vafa allow one to construct dual type II descriptions of these models (some of which have no weakly coupled heterotic dual). The dual type II models are given by the same orbifolds with the string coupling S and a T 2 volume T exchanged. This allows us to argue that in various strongly coupled limits of the original type II models, there are weakly coupled duals which exhibit the same perturbative cancellations as the original models

    Huang, Jun

    Type-II superlattice avalanche photodiodes have shown advantages compared to conventional mercury cadmium telluride photodiodes for infrared wavelength detection. However, surface or interface leakage current has been a major issue for superlattice avalanche photodiodes, especially in infrared wavelength region. First, passivation of the superlattice device with ammonium sulfide and thioacetamide was carried out, and its surface quality was studied by X-ray Photoelectron Spectroscopy. The study showed that both ammonium sulfide and thiacetamide passivation can actively remove the native oxide at the surface. Thiacetamide passivation combine more sulfur bonds with III-V elements than that of ammonium sulfide. Another X-ray photoelectron spectra of thiacetamide-treated atomic layer deposited zinc sulfide capped InAs/GaSb superlattice was performed to investigate the interface sulfur bond conditions. Sb--S and As--S bonds disappear while In-S bond gets enhanced, indicating that Indium Sulfide should be the major components at the interface after ZnS deposition. Second, the simulation of electrical characteristics for zinc sulfide, silicon nitride and silicon dioxide passivated superlattice devices was performed by SILVACO software to fit the experimental results and to discover the surface current mechanism. Different surface current mechanism strengths were found. Third, several novel dual-carrier avalanche photodiode structures were designed and simulated. The structures had alternate carrier multiplication regions, placed next to a wider electron multiplication region, creating dual-carrier multiplication feedback systems. Gain and excess noise factor of these structures were simulated and compared based on the dead space multiplication theory under uniform electric field. From the simulation, the applied bias can be greatly lowered or the thickness can be shrunk to achieve the same gain from the conventional device. The width of the thin region was the most

    Patient Blood Management (PBM) is the design of a personalized, multimodal multidisciplinary plan for minimizing transfusion and simultaneously achieving a positive impact on patient outcomes. The first pillar of PBM consists of optimizing the erythrocyte mass. The best chance for this step is offered by preoperative preparation. In most cases, a detailed medical history, physical examination and laboratory tests will identify the cause of anemia. A correct evaluation of parameters that assess the state and function of iron, such as ferritin levels, and the parameters that measure functional iron, such as transferrin saturation and soluble transferrin receptor levels, provide us with essential information for guiding the treatment with iron. The new blood count analyzers that measure hypochromia (% of hypochromic red blood cells and reticulocyte hemoglobin concentrations) provide us useful information for the diagnosis and follow-up of the response to iron treatment. Measuring serum folic acid and vitamin B12 levels is essential for treating deficiencies and thereby achieving better hemoglobin optimization.

    The present study was aimed to prove the usefulness of a new diagnostic plot (Hema-Plot), illustrating the relationship between the hemoglobin content of reticulocytes (Ret-He) as a marker of functional iron deficiency and the difference between the reticulocyte and erythrocyte hemoglobin content (Delta-He) as a marker of an impaired hemoglobinization of newly formed reticulocytes occurring during inflammatory processes, to differentiate between various disease-specific types of anemia. A complete blood and reticulocyte count was performed on routine EDTA blood samples from 345 patients with and without various disease-specific types of anemia using the Sysmex XN-9000 hematology analyzer: blood healthy newborns (n = 23), blood healthy adults (n = 31), patients suffering from anemia of chronic disease (ACD) due to diverse oncological, chronic inflammatory, or autoimmune diseases (total n = 138) with (n = 65) and without therapy (n = 73), patients with thalassemia and/or hemoglobinopathy (n = 18), patients with iron deficiency anemia (IDA) (n = 35), patients with a combination of ACD and IDA (n = 17), as well as patients suffering from sepsis (total n = 83) with (n = 32) and without therapy (n = 51). The results for Ret-He, Delta-He, and C-reactive protein (CRP) were statistically compared (Mann-Whitney U Test) between the particular patient groups and the diagnostic plots were drawn. Delta-Hemoglobin showed a statistically significant difference between blood healthy newborns and blood healthy adults (p ≤ 0.05), while Ret-He and C-reactive protein did not. In addition, of all three biomarkers only Delta-He showed a statistically significant difference (p ≤ 0.05) between the ACD/IDA and IDA cohort. Delta-He, Ret-He, and CRP showed a statistically significant difference between patient cohorts with and without therapy suffering from ACD, ACD/IDA, and sepsis before and after medical therapy (p ≤ 0.05). The Hema-Plot illustrated the dynamic character of Ret-He and

    Full Text Available Type II synthetic pyrethroids contain an alpha-cyano group which renders them more neurotoxic than their noncyano type I counterparts. A wide array of biomarkers have been employed to delineate the toxic responses of freshwater fish to various type II synthetic pyrethroids. These include hematological, enzymatic, cytological, genetic, omic and other types of biomarkers. This review puts together the applications of different biomarkers in freshwater fish species in response to the toxicity of the major type II pyrethroid pesticides and assesses their present status, while speculating on the possible future directions.

    Objective: To evaluate CT findings of liver and gallbladder in type II diabetics and to discuss diabetic, and investigate the correlation between type II diabetics, and investigate the correlation between the diabetes and the lesions found in the liver or gallbladder. Methods: Retrospective analysis was made on the CT findings of hepatic and gallbladder lesions in 586 cases of II diabetes. Results: In total 586 type II diabetics, cholecystitis and/or gallstone were revealed in 33.45% patients; and hepatic alteration was noted in 20.48% cases. Hepatic abnormalities were found in 58.67% cases in the cholecystitis/gallstone group, significantly different from the group with unremarkable gallbladder, in which hepatic lesions were found only in 1.28% cases. Conclusion: The hepatic alteration is secondary to the gallbladder lesions in type II diabetics. (authors)

    1996-01-01

    We report on a search for N=2 heterotic strings that are dual candidates of type II compactifications on Calabi-Yau threefolds described as K3 fibrations. We find many new heterotic duals by using standard orbifold techniques. The associated type II compactifications fall into chains in which the proposed duals are heterotic compactifications related one another by a sequential Higgs mechanism. This breaking in the heterotic side typically involves the sequence SU(4)\\rightarrow SU(3)\\rightarrow SU(2)\\rightarrow 0, while in the type II side the weights of the complex hypersurfaces and the structure of the K3 quotient singularities also follow specific patterns.

    Hemolytic anemia can be caused by various hereditary or acquired diseases. Classification is usually based on corpuscular or extracorpuscular defects. Beside the anemia, laboratory testing indicates increased lactate dehydrogenase, unconjugated bilirubin and reticulocytes as well as reduced or absent plasma haptoglobin. Knowledge of further diagnostic procedures (e.g., Coombs test, schistocytes, hemoglobin electrophoresis or flow cytometric analysis) leads in many cases to an underlying disease with differentiated therapeutic options. Autoimmune hemolytic anemia (AIHA) is often associated with diseases as HIV, connective tissue disease, lymphomas or malignant tumors and the hemolytic process is preexisting in many cases. Thrombotic microvascular diseases (e.g., thrombotic thrombocytopenic purpura or hemolytic-uremic syndrome) are further important causes of hemolytic anemia which need immediate diagnosis and treatment.

  1. Distinct roles of urinary liver-type fatty acid-binding protein in non-diabetic patients with anemia.

    Naohiko Imai

    Full Text Available Various stresses including ischemia are known to up-regulate renal L-FABP gene expression and increase the urinary excretion of L-FABP. In diabetic patients with anemia, the urinary excretion of L-FABP is significantly increased. We studied the clinical significance of urinary L-FABP and its relationship with anemia in non-diabetic patients.A total of 156 patients were studied in this retrospective cross-sectional analysis. The associations between anemia and urinary L-FABP levels, and the predictors of urinary L-FABP levels in non-diabetic patients were evaluated.Urinary L-FABP levels were significantly higher in patients with anemia compared to those in patients without anemia. Similarly, the urinary L-FABP levels were significantly higher in patients with albuminuria compared to those in patients without albuminuria. Urinary L-FABP levels correlated with urinary albumin-to-creatinine ratios, estimated glomerular filtration rates, body mass index, and hemoglobin levels. Multivariate linear regression analysis determined that hemoglobin levels (β = -0.249, P = 0.001 and urinary albumin-to-creatinine ratios (β = 0.349, P < 0.001 were significant predictors of urinary L-FABP levels.Urinary L-FABP is strongly associated with anemia in non-diabetic patients.

    Acoustic information propagates from the ear to the brain via spiral ganglion neurons that innervate hair cells in the cochlea. These afferents include unmyelinated type II fibers that constitute 5 % of the total, the majority being myelinated type I neurons. Lack of specific genetic markers of type II afferents in the cochlea has been a roadblock in studying their functional role. Unexpectedly, type II afferents were visualized by reporter proteins induced by tyrosine hydroxylase (TH)-driven Cre recombinase. The present study was designed to determine whether TH-driven Cre recombinase (TH-2A-CreER) provides a selective and reliable tool for identification and genetic manipulation of type II rather than type I cochlear afferents. The "TH-2A-CreER neurons" radiated from the spiral lamina, crossed the tunnel of Corti, turned towards the base of the cochlea, and traveled beneath the rows of outer hair cells. Neither the processes nor the somata of TH-2A-CreER neurons were labeled by antibodies that specifically labeled type I afferents and medial efferents. TH-2A-CreER-positive processes partially co-labeled with antibodies to peripherin, a known marker of type II afferents. Individual TH-2A-CreER neurons gave off short branches contacting 7-25 outer hair cells (OHCs). Only a fraction of TH-2A-CreER boutons were associated with CtBP2-immunopositive ribbons. These results show that TH-2A-CreER provides a selective marker for type II versus type I afferents and can be used to describe the morphology and arborization pattern of type II cochlear afferents in the mouse cochlea.

    Full Text Available Abstract Background Bacterial aromatic polyketides are a pharmacologically important group of natural products synthesized by type II polyketide synthases (type II PKSs in actinobacteria. Isolation of novel aromatic polyketides from microbial sources is currently impeded because of the lack of knowledge about prolific taxa for polyketide synthesis and the difficulties in finding and optimizing target microorganisms. Comprehensive analysis of type II PKSs and the prediction of possible polyketide chemotypes in various actinobacterial genomes will thus enable the discovery or synthesis of novel polyketides in the most plausible microorganisms. Description We performed a comprehensive computational analysis of type II PKSs and their gene clusters in actinobacterial genomes. By identifying type II PKS subclasses from the sequence analysis of 280 known type II PKSs, we developed highly accurate domain classifiers for these subclasses and derived prediction rules for aromatic polyketide chemotypes generated by different combinations of type II PKS domains. Using 319 available actinobacterial genomes, we predicted 231 type II PKSs from 40 PKS gene clusters in 25 actinobacterial genomes, and polyketide chemotypes corresponding to 22 novel PKS gene clusters in 16 genomes. These results showed that the microorganisms capable of producing aromatic polyketides are specifically distributed within a certain suborder of Actinomycetales such as Catenulisporineae, Frankineae, Micrococcineae, Micromonosporineae, Pseudonocardineae, Streptomycineae, and Streptosporangineae. Conclusions We could identify the novel candidates of type II PKS gene clusters and their polyketide chemotypes in actinobacterial genomes by comprehensive analysis of type II PKSs and prediction of aromatic polyketides.

    1995-05-01

    To determine the significance of type II fiber atrophy in alcoholic myopathy and its relationship with ethanol-related diseases a prospective study was carried out in 100 chronic alcoholics who showed clinical suspicion of skeletal myopathy. Measurement of muscle strength, laboratory analysis, nutritional assessment and open biopsy of deltoid muscle were performed in each case, as well as electrophysiological testing for peripheral neuropathy. Hepatic ultrasonography and liver biopsy, echocardiography and radionuclide cardiac scanning were carried out in selected subjects. According to histomorphometric analysis, type II fiber atrophy was found in 33 cases (33%), being selective for type II B fiber in 23 (70%). Skeletal myopathy was diagnosed in 61 cases, alcoholic cardiomyopathy in 26, peripheral neuropathy in 23 and cirrhosis in 12. Patients with type II fiber atrophy had a significantly higher total lifetime dose of ethanol, presented a greater incidence of skeletal myopathy and peripheral neuropathy, and exhibited significantly lower values of percentage of ideal body weight and lean body mass than their counterparts. However, the only independent factors for developing type II fiber atrophy were the coexistence of caloric malnutrition (p = 0.004) and the presence of skeletal myopathy (p = 0.043). Selective type II fiber atrophy is a non-specific finding in alcohol-induced muscle damage appearing, overall, in the patients with caloric malnutrition as well as in those with histologic evidence of myopathy.

  19. Anomalous Nernst effect in type-II Weyl semimetals

    Science.gov (United States)

    Saha, Subhodip; Tewari, Sumanta

    2018-01-01

    Topological Weyl semimetals (WSM), a new state of quantum matter with gapless nodal bulk spectrum and open Fermi arc surface states, have recently sparked enormous interest in condensed matter physics. Based on the symmetry and fermiology, it has been proposed that WSMs can be broadly classified into two types, type-I and type-II Weyl semimetals. While the undoped, conventional, type-I WSMs have point like Fermi surface and vanishing density of states (DOS) at the Fermi energy, the type-II Weyl semimetals break Lorentz symmetry explicitly and have tilted conical spectra with electron and hole pockets producing finite DOS at the Fermi level. The tilted conical spectrum and finite DOS at Fermi level in type-II WSMs have recently been shown to produce interesting effects such as a chiral anomaly induced longitudinal magnetoresistance that is strongly anisotropic in direction and a novel anomalous Hall effect. In this work, we consider the anomalous Nernst effect in type-II WSMs in the absence of an external magnetic field using the framework of semi-classical Boltzmann theory. Based on both a linearized model of time-reversal breaking WSM with a higher energy cut-off and a more realistic lattice model, we show that the anomalous Nernst response in these systems is strongly anisotropic in space, and can serve as a reliable signature of type-II Weyl semimetals in a host of magnetic systems with spontaneously broken time reversal symmetry.

  1. Downregulation of angiotensin II type 1 receptors during sepsis.

    Bucher, M; Ittner, K P; Hobbhahn, J; Taeger, K; Kurtz, A

    2001-08-01

    Our study aimed to characterize the mechanisms underlying the attenuated cardiovascular responsiveness toward the renin-angiotensin system during sepsis. For this purpose, we determined the effects of experimental Gram-negative and Gram-positive sepsis in rats. We found that sepsis led to a ubiquitous upregulation of NO synthase isoform II expression and to pronounced hypotension. Despite increased plasma renin activity and plasma angiotensin (Ang) II levels, plasma aldosterone concentrations were normal, and the blood pressure response to exogenous Ang II was markedly diminished in septic rats. Mimicking the fall of blood pressure during sepsis by short-term infusion of the NO donor sodium nitroprusside in normal rats did not alter their blood pressure response to exogenous Ang II. Therefore, we considered the possibility of an altered expression of Ang II receptors during sepsis. It turned out that Ang II type 1 receptor expression was markedly downregulated in all organs of septic rats. Further in vitro studies with rat renal mesangial cells showed that NO and a combination of proinflammatory cytokines (interleukin-1beta, tumor necrosis factor-alpha, and interferon-gamma) downregulated Ang II type 1 receptor expression in a synergistic fashion. In summary, our data suggest that sepsis causes a systemic downregulation of Ang II type 1 receptors that is likely mediated by proinflammatory cytokines and NO. We suggest that this downregulation of Ang II type 1 receptors is the main reason for the attenuated responsiveness of blood pressure and of aldosterone formation to Ang II and, therefore, contributes to the characteristic septic shock.

    2015-09-01

    Erythropoiesis is a continuous process that replaces 1% of all erythrocytes per day. To keep the erythrocyte count within stable limits about 3 million cells/s must be renewed. This enormous turnover requires folic acid and vitamin B12 for proper cell differentiation and iron for sufficient haemoglobin synthesis. In particular, iron metabolism underlies a precise regulation which may be disturbed by chronic bleeding, inflammatory disease or impaired dietary intake. If the loss of red blood cells due to physiological aging or bleeding is not balanced by sufficient erythropoiesis in the bone marrow, anaemia will develop. For the classification of various types of anaemia, a well-established algorithm has been proven useful. This algorithm addresses basic questions such as erythrocyte volume, the underlying mechanism, e.g. whether too many cells are destroyed or new cells are not sufficiently generated, and finally aims to define the main causes for the above identified disturbance of erythropoiesis.

    2017-04-15

    We have investigated a nanostructured material known as sub-monolayer type-II QDs, made from wide bandgap II-VI semiconductors. Our goal is to understand and exploit their tunable optical and electrical properties by taking advantage of the type-II band alignment and quantum confinement effects. Type-II ZnTe quantum dots (QDs) in a ZnSe host are particularly interesting because of their relatively large valence band and conduction band offsets. In the current award we have developed new materials based on sub-monolayer type-II QDs that may be advantageous for photovoltaic and spintronics applications. We have also expanded the structural characterization of these materials by refining the X-ray diffraction methodologies needed to investigate them. In particular, we have 1) demonstrated ZnCdTe/ZnCdSe type-II QDs materials that have ideal properties for the development of novel high efficiency “intermediate band solar cells”, 2) we developed a comprehensive approach to describe and model the growth of these ultra-small type-II QDs, 3) analysis of the evolution of the photoluminescence (PL) emission, combined with other characterization probes allowed us to predict the size and density of the QDs as a function of the growth conditions, 4) we developed and implemented novel sophisticated X-ray diffraction techniques from which accurate size and shape of the buried type-II QDs could be extracted, 5) a correlation of the shape anisotropy with polarization dependent PL was observed, confirming the QDs detailed shape and providing insight about the effects of this shape anisotropy on the physical properties of the type-II QD systems, and 6) a detailed “time-resolved Kerr rotation” investigation has led to the demonstration of enhanced electron spin lifetimes for the samples with large densities of type-II QDs and an understanding of the interplay between the QDs and Te-isoelectroic centers, a defect that forms in the spacer layers that separate the QDs.

    Full Text Available Sideroblastic anemias are a heterogenous group of disorders that have as a common feature with the presence of ringed sideroblasts in the marrow. We present a case of young female, nursing student who presented with increasing palpitation, fatigue and exertional shortness of breath for the last one year. She had a low hemoglobin and high serum iron. Anemia with iron overload prompted us to do bone marrow study and there were 19% ringed sideroblasts and iron overload fulfilling the diagnosis of sideroblastic anemia. We searched for secondary causes of ringed sideroblast but could not find any culprit. Her cytogenetics report was normal and genetic analysis was not done due to financial reason. Since the diagnosis 3 months back, patient is on pyridoxine, folic acid, deferasirox and still needs regular blood transfusion suggesting that she may be pyridoxine refractory and may develop iron overload.

    To assess the different kinds of anaemia in childhood 468 children of Large Tunis and 487 children of the Western South like 744 of the urban environment and 211 children of the rural medium were studied. 21.3% of the old children from 6 to 59 months of Large Tunis present a ferriprive anaemia and 18% for the Western South. 20.7% of the children of the urban environment present against a ferriprive anaemia 19.1% for the rural medium but these results remain non significant. 1.1% of the children of Large Tunis present a martial anaemia associated with an ignition and 0.6% of the surveyed children are touched by this type of anaemia in the Western South. This association touches especially the urban environment with a rate of 1.1% against 0% for the rural medium. The proportion of the feeble children by deficiency in folic acid remains very low as for that by deficiency in B12 vitamin. The majority of the children of Large Tunis (2.9%) are touched by B minor thalassaemia and 1.3% of the children of the Western South are touched by the feature drépanocytaire. The major cause of anaemia for the children of less than 5 years thus remains ferriprive.

    Full Text Available Background: Microcytic hypochromic anemia is a distinct morphologic subtype of anemia with well- de ned etiology and treatment. The objective of this study was to determine the etiology and frequency of microcytic hypochromic anemia. Materials and Methods: This cross-sectional observational study was conducted at Kathmandu Medical College Teaching Hospital. One hundred cases of microcytic hypochromic anemia were included. Relevant clinical history, hemogram, reticulocyte count, iron pro les were documented in a proforma. Bone marrow aspiration and hemoglobin electrophoresis was conducted when required. Data was analysed by Microsoft SPSS 16 windows. Result: Iron de ciency was the commonest etiology (49%. Dysfunctional uterine bleeding (20.8% was the commonest cause of iron de ciency, malignancy (24.3% was the commonest cause of anemia of chronic disease. Mean value of Mean Corpuscular Volume was lowest in hemolytic anemia (71.0 . Mean Red cell Distribution Width was normal (14.0% in hemolytic anemia but was raised in other types. Mean serum iron was reduced in iron de ciency anemia (32.2μg/dl and chronic disease (34.8μg/dl, normal in hemolytic anemia (83μg/dl and raised in sideroblastic anemia (295μg/dl. Mean serum ferritin was reduced in iron de ciency anemia (7.6ng/ml, raised in chronic disease (158.6ng/ml and normal in hemolytic anemia (99.2ng/ml. Serum ferritin was normal in sideroblastic anemia (93ng/ml. Mean Total Iron Binding Capacity was raised in iron de ciency anemia (458μg/dl and normal in other microcytic hypochromic anemias. Conclusion: Diagnosis of microcytic hypochromic anemia requires a standardized approach which includes clinical details, hemogram, peripheral blood smear, reticulocyte count, iron pro le, hemoglobin electrophoresis and bone marrow examination. 

  11. Glutathione synthesis and homeostasis in isolated type II alveolar cells

    After isolation of Type II cells from neonatal rat lung, the glutathione (GSH) levels in these cells were greatly depressed. The total glutathione content could be increased 5-fold within 12-24 h by incubating the cells in media containing sulfur amino acids. Similarly, the activity of γ-glutamyltranspeptidase was low immediately after isolation, but was increased 2-fold during the first 24 h culture. Addition of either GSH or GSSG to the culture media increased the GSH content of Type II cells 2-2.5-fold. Buthionine sulfoximine and NaF prevented this replenishment of GSH during 24 h culture. When the rates of de novo synthesis of GSH and GSSG from 35 S-cysteine were measured, the amounts of newly formed GSH decreased to 80% in the presence of GSH or GSSG. This suggests that exogenous GSH/GSSG can be taken up by the Type II cells to replenish the intracellular pool of GSH. Methionine was not as effective as cysteine in the synthesis of GSH. These results suggest that GSH levels in the isolated Type II cell can be maintained by de novo synthesis or uptake of exogenous GSH. Most of the GSH synthesized from cysteine, however, was excreted into the media of the cultured cells indicative of a potential role for the type II cell in export of the non-protein thiol

  12. A Statistical Study of Interplanetary Type II Bursts: STEREO Observations

    Coronal mass ejections (CMEs) are the primary cause of the most severe and disruptive space weather events such as solar energetic particle (SEP) events and geomagnetic storms at Earth. Interplanetary type II bursts are generated via the plasma emission mechanism by energetic electrons accelerated at CME-driven shock waves and hence identify CMEs that potentially cause space weather impact. As CMEs propagate outward from the Sun, radio emissions are generated at progressively at lower frequencies corresponding to a decreasing ambient solar wind plasma density. We have performed a statistical study of 153 interplanetary type II bursts observed by the two STEREO spacecraft between March 2008 and August 2014. These events have been correlated with manually-identified CMEs contained in the Heliospheric Cataloguing, Analysis and Techniques Service (HELCATS) catalogue. Our results confirm that faster CMEs are more likely to produce interplanetary type II radio bursts. We have compared observed frequency drifts with white-light observations to estimate angular deviations of type II burst propagation directions from radial. We have found that interplanetary type II bursts preferably arise from CME flanks. Finally, we discuss a visibility of radio emissions in relation to the CME propagation direction.

    Full Text Available Background/Aims. Patients with type II diabetes mellitus (DM were known to have higher prevalence of gastroesophageal reflux disease (GERD in the Western countries, but data on the impact of GERD on DM patients in our country are scarce. The aim of this study was to evaluate the prevalence of GERD in type II DM patients in Shanghai, China, and to explore its possible risk factors. Methods. 775 type II DM cases were randomly collected. Reflux Disease Questionnaire (RDQ was used to check the presence of GERD. Patients’ characteristics, laboratory data, face-to-face interview, nerve conduction study, and needle electromyogram (EMG test were analyzed. Results. 16% patients were found with typical GERD symptoms. Pathophysiological factors such as peripheral neuropathy, metabolism syndrome, and obesity were found to have no significant differences between GERD and non-GERD type II DM patients in the present study. Conclusion. The prevalence of GERD in type II DM patients is higher than that in adult inhabitants in Shanghai, China. No difference in pathophysiological factors, such as peripheral neuropathy, and metabolism syndrome was found in DM-GERD patients, suggesting that further study and efforts are needed to explore deeper the potential risk factors for the high prevalence rate of GERD in DM patients.

    The progenitors of low-luminosity Type II-Plateau supernovae (SNe II-P) are believed to be red supergiant (RSG) stars, but there is much disparity in the literature concerning their mass at core collapse and therefore on the main sequence. Here, we model the SN radiation arising from the low-energy explosion of RSG stars of 12, 25 and 27 M⊙ on the main sequence and formed through single star evolution. Despite the narrow range in ejecta kinetic energy (2.5-4.2 × 1050 erg) in our model set, the SN observables from our three models are significantly distinct, reflecting the differences in progenitor structure (e.g. surface radius, H-rich envelope mass and He-core mass). Our higher mass RSG stars give rise to Type II SNe that tend to have bluer colours at early times, a shorter photospheric phase, and a faster declining V-band light curve (LC) more typical of Type II-linear SNe, in conflict with the LC plateau observed for low-luminosity SNe II. The complete fallback of the CO core in the low-energy explosions of our high-mass RSG stars prevents the ejection of any 56Ni (nor any core O or Si), in contrast to low-luminosity SNe II-P, which eject at least 0.001 M⊙ of 56Ni. In contrast to observations, Type II SN models from higher mass RSGs tend to show an H α absorption that remains broad at late times (due to a larger velocity at the base of the H-rich envelope). In agreement with the analyses of pre-explosion photometry, we conclude that low-luminosity SNe II-P likely arise from low-mass rather than high-mass RSG stars.

    We report on a study of the time-resolved luminescence of type-II GaAs/AlAs superlattices near the type-I to type-II crossover. In spite of the slight type-II band alignment, the luminescence is dominated by the type-I transition. This is due to the inhomogeneous broadening of the type-I transition...... and the weak type-II oscillator strength, leading to a dominant luminescence of deeply localized type-I states. The relaxation within these localized states is found to be in agreement with a hopping model. At higher temperatures and excitation densities, the AlAs X minima act as an electron reservoir, leading...

    2010-01-01

    Grand unified theories where the neutrino mass is given by Type II seesaw have the potential to provide interesting connections between the neutrino and charged fermion sectors. We explore the possibility of having a dominant Type II seesaw contribution in supersymmetric SO(10). We show that this can be achieved in the model where symmetry breaking is triggered by 54 and 45-dimensional representations, without the need for additional fields other than those already required to have a realistic charged fermion mass spectrum. Physical consequences, such as the implementation of the BSV mechanism, the possibility of the fields responsible for Type II see-saw dominance being messengers of supersymmetry breaking, and the realization of baryo and leptogenesis in this theories are discussed.

    Hemolytic anemias consist of corpuscular, immun-hemolytic and toxic hemolytic anemias. Within the group of corpuscular hemolytic anemias, except for the paroxysmal nocturnal hemoglobinuria (PNH), all symptoms are caused by underlying heredetiary disorders within the red blood cell membran (hereditary spherocytosis), deficiencies of red cell enzymes (G6PDH- and pyrovatkinase deficiency) or disorders in the hemoglobin molecule (thalassaemia and sickle cell disease). Immune-hemolytic anemias are acquired hemolytic anemias and hemolysis is caused by auto- or allo-antibodies which are directed against red blood cell antigens. They are classified as warm, cold, mixed type or drug-induced hemolytic anemia. Therapy consists of glucocorticoids and other immunsuppressive drugs. Pernicious anemia is the most important vitamin B12 deficiency disorder. Diagnosis relies on cobalamin deficiency and antibodies to intrinsic factor. The management should focus on a possibly life-long replacement treatment with cobalamin. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Abstract Background The mechanisms that consolidate neural circuitry are a major focus of neuroscience. In the mammalian cochlea, the refinement of spiral ganglion neuron (SGN innervation to the inner hair cells (by type I SGNs and the outer hair cells (by type II SGNs is accompanied by a 25% loss of SGNs. Results We investigated the segregation of neuronal loss in the mouse cochlea using β-tubulin and peripherin antisera to immunolabel all SGNs and selectively type II SGNs, respectively, and discovered that it is the type II SGN population that is predominately lost within the first postnatal week. Developmental neuronal loss has been attributed to the decline in neurotrophin expression by the target hair cells during this period, so we next examined survival of SGN sub-populations using tissue culture of the mid apex-mid turn region of neonatal mouse cochleae. In organotypic culture for 48 hours from postnatal day 1, endogenous trophic support from the organ of Corti proved sufficient to maintain all type II SGNs; however, a large proportion of type I SGNs were lost. Culture of the spiral ganglion as an explant, with removal of the organ of Corti, led to loss of the majority of both SGN sub-types. Brain-derived neurotrophic factor (BDNF added as a supplement to the media rescued a significant proportion of the SGNs, particularly the type II SGNs, which also showed increased neuritogenesis. The known decline in BDNF production by the rodent sensory epithelium after birth is therefore a likely mediator of type II neuron apoptosis. Conclusion Our study thus indicates that BDNF supply from the organ of Corti supports consolidation of type II innervation in the neonatal mouse cochlea. In contrast, type I SGNs likely rely on additional sources for trophic support.

  1. Evidence for topological type-II Weyl semimetal WTe2

    KAUST Repository

    Li, Peng

    2017-12-11

    Recently, a type-II Weyl fermion was theoretically predicted to appear at the contact of electron and hole Fermi surface pockets. A distinguishing feature of the surfaces of type-II Weyl semimetals is the existence of topological surface states, so-called Fermi arcs. Although WTe2 was the first material suggested as a type-II Weyl semimetal, the direct observation of its tilting Weyl cone and Fermi arc has not yet been successful. Here, we show strong evidence that WTe2 is a type-II Weyl semimetal by observing two unique transport properties simultaneously in one WTe2 nanoribbon. The negative magnetoresistance induced by a chiral anomaly is quite anisotropic in WTe2 nanoribbons, which is present in b-axis ribbon, but is absent in a-axis ribbon. An extra-quantum oscillation, arising from a Weyl orbit formed by the Fermi arc and bulk Landau levels, displays a two dimensional feature and decays as the thickness increases in WTe2 nanoribbon.

    2014-07-01

    This article continues the series of Surveys and Summaries on restriction endonucleases (REases) begun this year in Nucleic Acids Research. Here we discuss 'Type II' REases, the kind used for DNA analysis and cloning. We focus on their biochemistry: what they are, what they do, and how they do it. Type II REases are produced by prokaryotes to combat bacteriophages. With extreme accuracy, each recognizes a particular sequence in double-stranded DNA and cleaves at a fixed position within or nearby. The discoveries of these enzymes in the 1970s, and of the uses to which they could be put, have since impacted every corner of the life sciences. They became the enabling tools of molecular biology, genetics and biotechnology, and made analysis at the most fundamental levels routine. Hundreds of different REases have been discovered and are available commercially. Their genes have been cloned, sequenced and overexpressed. Most have been characterized to some extent, but few have been studied in depth. Here, we describe the original discoveries in this field, and the properties of the first Type II REases investigated. We discuss the mechanisms of sequence recognition and catalysis, and the varied oligomeric modes in which Type II REases act. We describe the surprising heterogeneity revealed by comparisons of their sequences and structures. © The Author(s) 2014. Published by Oxford University Press on behalf of Nucleic Acids Research.

    Type II thyroplasty, or laryngeal framework surgery, is based on the hypothesis that the effect of adductor spasmodic dysphonia (AdSD) on the voice is due to excessively tight closure of the glottis, hampering phonation. Most of the previous, partially effective treatments have aimed to relieve this tight closure, including recurrent laryngeal nerve section or avulsion, extirpation of the adductor muscle, and botulinum toxin injection, which is currently the most popular. The aim of this study was to assess the effects of type II thyroplasty on aerodynamic and acoustic findings in patients with AdSD. Case series. University hospital. Ten patients with AdSD underwent type II thyroplasty between August 2006 and December 2008. Aerodynamic and acoustic analyses were performed prior to and six months after surgery. Mean flow rates (MFRs) and voice efficiency were evaluated with a phonation analyzer. Jitter, shimmer, the harmonics-to-noise ratio (HNR), standard deviation of the fundamental frequency (SDF0), and degree of voice breaks (DVB) were measured from each subject's longest sustained phonation sample of the vowel /a/. Voice efficiency improved significantly after surgery. No significant difference was found in the MFRs between before and after surgery. Jitter, shimmer, HNR, SDF0, and DVB improved significantly after surgery. Treatment of AdSD with type II thyroplasty significantly improved aerodynamic and acoustic findings. The results of this study suggest that type II thyroplasty provides relief from voice strangulation in patients with AdSD.

  10. Clinical aspects and pathogenesis of congenital dyserythropoietic anemias: from morphology to molecular approach.

    Science.gov (United States)

    Iolascon, Achille; Esposito, Maria Rosaria; Russo, Roberta

    2012-12-01

    Congenital dyserythropoietic anemias belong to a group of inherited conditions characterized by a maturation arrest during erythropoiesis with a reduced reticulocyte production in contrast with erythroid hyperplasia in bone marrow. The latter shows specific morphological abnormalities that allowed for a morphological classification of these conditions mainly represented by congenital dyserythropoietic anemias types I and II. The identification of their causative genes provided evidence that these conditions have different molecular mechanisms that induce abnormal cell maturation and division. Some altered proteins seem to be involved in the chromatin assembly, such as codanin-1 in congenital dyserythropoietic anemia I. The gene involved in congenital dyserythropoietic anemia II, the most frequent form, is SEC23B. This condition seems to belong to a group of diseases attributable to defects in the transport of newly synthesized proteins from endoplasmic reticulum to the Golgi. This review will analyze recent insights in congenital dyserythropoietic anemias types I and II. It will also attempt to clarify the relationship between mutations in causative genes and the clinical phenotype of these conditions.

    We describe a patient with low-titer cold agglutinin disease (CAD) who developed mixed-type autoimmune hemolytic anemia (AIHA) and idiopathic thrombocytopenia following chicken pox infection. At least 1 year before admission to hospital, the patient had mild hemolytic anemia associated with low-titer cold agglutinins. A severe hemolytic crisis and thrombocytopenia (Evans' syndrome) occurred several days after infection with chicken pox, and the patient was referred to our hospital. Serological findings revealed the presence of both cold agglutinins and warm-reactive autoantibodies against erythrocytes, and the diagnosis was mixed-type AIHA. Following steroid therapy, the hemoglobin (Hb) level and platelet count improved. The patient was closely followed over a 10-year period with recurrent documented hemolysis after viral or bacterial infections. Warm-reactive autoantibodies have not been detected in the last 2 years, and only the immunoglobulin M anti-I cold agglutinins with a low titer and wide thermal amplitude have remained unchanged. Therefore, the patient has received at least 10 mg prednisolone daily to maintain a Hb level of 10 g/dL. To the best of our knowledge, no adult case of low-titer CAD that has evolved into mixed-type AIHA and Evans' syndrome after chicken pox infection has been previously reported in the literature.

    Sparse data are available about the natural history of hemoglobin (Hb) level trends in contemporary patients with anemia, chronic kidney disease (CKD), and type 2 diabetes mellitus. We intended to describe Hb level trends over time with no or minimal administration of erythropoiesis-stimulating agents. Prospective clinical trial cohort. 2,019 individuals with type 2 diabetes, moderate anemia, and CKD from the placebo arm of the Trial to Reduce Cardiovascular Events With Aranesp Therapy (TREAT) followed up for 2.3 years with an average of 32 monthly Hb level determinations per patient. Darbepoetin alfa was administered only if Hb level decreased to protocol-directed doses of darbepoetin alfa received due to an Hb level decrease to protocol-directed darbepoetin alfa. The other patients received 1 (16%), 2-4 (16%), or 5 or more (13%) doses of darbepoetin alfa. Those who received no darbepoetin alfa doses had higher baseline Hb levels, higher estimated glomerular filtration rates (eGFRs), less proteinuria, and lower ferritin and transferrin saturation values. On average, Hb levels were stable or increased in all groups. Compared with individuals who received no darbepoetin alfa, those who received 5 or more doses were more likely to receive intravenous iron therapy and blood transfusions and progress to renal replacement therapy, but were not at higher risk of death. The strongest predictors of requiring 5 or more doses of darbepoetin alfa were lower baseline Hb level, lower eGFR, and higher proteinuria level. Post hoc analysis of a clinical trial of a specific population with diabetes, anemia, and non-dialysis-dependent CKD. In the TREAT placebo arm, Hb levels were stable with no or minimal protocol-directed darbepoetin alfa during 2.3 years of follow-up. Most patients with moderate anemia, non-dialysis-dependent CKD, and type 2 diabetes are able to maintain a stable Hb level without implementing long-term erythropoiesis-stimulating agent therapy.

    1988-01-01

    Repopulation of denuded heterotopic tracheal grafts with populations of specific epithelial cell types is one approach to study the differentiation potential of various cell types. This technique has been adopted to delineate the differentiation pathways of alveolar type II cells isolated from rat lungs. Under the conditions of this experiment, the reestablished epithelial lining was alveolar-like, however, ultrastructural analysis of the cells showed them to be like Clara cells. These preliminary results suggest that the secretary cells of the lung parenchyma and terminal airways may share a common ancestry. (author)

  2. Intrafibrillar Mineral May be Absent in Dentinogenesis Imperfecta Type II (DI-II)

    Energy Technology Data Exchange (ETDEWEB)

    Pople, John A

    2001-03-29

    High-resolution synchrotron radiation computed tomography (SRCT) and small angle x-ray scattering (SAXS) were performed on normal and dentinogenesis imperfecta type II (DI-II) teeth. Three normal and three DI-II human third molars were used in this study. The normal molars were unerupted and had intact enamel; donors were female and ranged in age from 18-21y. The DI-II specimens, which were also unerupted with intact enamel, came from a single female donor age 20y. SRCT showed that the mineral concentration was 33% lower on average in the DI-II dentin with respect to normal dentin. The SAXS spectra from normal dentin exhibited low-angle diffraction peaks at harmonics of 67.6 nm, consistent with nucleation and growth of the apatite phase within gaps in the collagen fibrils (intrafibrillar mineralization). In contrast, the low-angle peaks were almost nonexistent in the DI-II dentin. Crystallite thickness was independent of location in both DI-II and normal dentin, although the crystallites were significantly thicker in DI-II dentin (6.8 nm (s.d. = 0.5) vs 5.1 nm (s.d. = 0.6)). The shape factor of the crystallites, as determined by SAXS, showed a continuous progression in normal dentin from roughly one-dimensional (needle-like) near the pulp to two-dimensional (plate-like) near the dentin-enamel junction. The crystallites in DI-II dentin, on the other hand, remained needle-like throughout. The above observations are consistent with an absence of intrafibrillar mineral in DI-II dentin.

  3. Hybrid type I-type II superconducting behavior in magnesium diboride

    In traditional type-II superconductors, an applied magnetic field depresses the transition temperature and introduces magnetic flux vortices that cause resistive losses accompanied by a broadening of the transition. High-field high-pulsed-current measurements have revealed a new hybrid behavior in disordered magnesium diboride films: The superconductivity survives high magnetic fields by entering a mixed state with vortices (like a type II superconductor) but holds its vortices nearly motionless and avoids dissipation (like a type I superconductor). A study of this phenomenon in magnesium diboride films with varying degrees of scattering indicate that the hybrid type I-type II behavior arises from the two-band nature of the superconductivity and the different degrees of influence that disorder exerts on its different bands.

  8. Type II restriction endonucleases—a historical perspective and more

    Pingoud, Alfred; Wilson, Geoffrey G.; Wende, Wolfgang

    2014-01-01

    This article continues the series of Surveys and Summaries on restriction endonucleases (REases) begun this year in Nucleic Acids Research. Here we discuss ‘Type II’ REases, the kind used for DNA analysis and cloning. We focus on their biochemistry: what they are, what they do, and how they do it. Type II REases are produced by prokaryotes to combat bacteriophages. With extreme accuracy, each recognizes a particular sequence in double-stranded DNA and cleaves at a fixed position within or nearby. The discoveries of these enzymes in the 1970s, and of the uses to which they could be put, have since impacted every corner of the life sciences. They became the enabling tools of molecular biology, genetics and biotechnology, and made analysis at the most fundamental levels routine. Hundreds of different REases have been discovered and are available commercially. Their genes have been cloned, sequenced and overexpressed. Most have been characterized to some extent, but few have been studied in depth. Here, we describe the original discoveries in this field, and the properties of the first Type II REases investigated. We discuss the mechanisms of sequence recognition and catalysis, and the varied oligomeric modes in which Type II REases act. We describe the surprising heterogeneity revealed by comparisons of their sequences and structures. PMID:24878924

  9. Inhibition of Zn(II binding type IA topoisomerases by organomercury compounds and Hg(II.

    Directory of Open Access Journals (Sweden)

    Bokun Cheng

    Full Text Available Type IA topoisomerase activities are essential for resolving DNA topological barriers via an enzyme-mediated transient single strand DNA break. Accumulation of topoisomerase DNA cleavage product can lead to cell death or genomic rearrangement. Many antibacterial and anticancer drugs act as topoisomerase poison inhibitors that form stabilized ternary complexes with the topoisomerase covalent intermediate, so it is desirable to identify such inhibitors for type IA topoisomerases. Here we report that organomercury compounds were identified during a fluorescence based screening of the NIH diversity set of small molecules for topoisomerase inhibitors that can increase the DNA cleavage product of Yersinia pestis topoisomerase I. Inhibition of relaxation activity and accumulation of DNA cleavage product were confirmed for these organomercury compounds in gel based assays of Escherichia coli topoisomerase I. Hg(II, but not As(III, could also target the cysteines that form the multiple Zn(II binding tetra-cysteine motifs found in the C-terminal domains of these bacterial topoisomerase I for relaxation activity inhibition. Mycobacterium tuberculosis topoisomerase I activity is not sensitive to Hg(II or the organomercury compounds due to the absence of the Zn(II binding cysteines. It is significant that the type IA topoisomerases with Zn(II binding domains can still cleave DNA when interfered by Hg(II or organomercury compounds. The Zn(II binding domains found in human Top3α and Top3β may be potential targets of toxic metals and organometallic complexes, with potential consequence on genomic stability and development.

  13. Instability in the magnetic field penetration in type II superconductors

    Energy Technology Data Exchange (ETDEWEB)

    Oliveira, Isaías G. de, E-mail: isaias@ufrrj.br

    2015-07-17

    Under the view of the time-dependent Ginzburg–Landau theory we have investigated the penetration of the magnetic field in the type II superconductors. We show that the single vortices, situated along the borderline, between the normal region channel and the superconducting region, can escape to regions still empty of vortices. We show that the origin of this process is the repulsive nature of vortex–vortex interaction, in addition to the non-homogeneous distribution of the vortices along the normal region channel. Using London theory we explain the extra gain of kinetic energy by the vortices situated along this borderline. - Highlights: • TDGL is used to study the magnetic field penetration in type II superconductors. • Instability process is found during the magnetic field penetration. • Vortices along the front of the normal region escape to superconducting region. • We explain the extra-gain of kinetic energy by vortices along the borderline.

  14. Subclinical onychomycosis in patients with type II diabetes

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available Fungal organisms could be present in the nail without any clinical manifestations. As onychomycosis in diabetics has more serious complications, early detection of such infection could be helpful to prevent them. We aim in this study to assess the possibility of detecting subclinical onychomycosis in type II diabetic patients and addressing possible associated neuropathy. A cross sectional, observational study included patients with type II diabetes with normal big toe nail. All were subjected to nail clipping of the big toe nail, followed by staining with Hematoxylin and Eosin and Periodic-Acid-Schiff (PAS stains and examined microscopically. A total of 106 patients were included, fungal infection was identified in eight specimens, all were uncontrolled diabetes, and six had neuropathy. Using the nail clipping and microscopic examination with PAS stain to detect such subclinical infection could be an applicable screening test for diabetic patients, for early detection and management of onychomycosis.

    2016-01-01

    We present a compilation of UBVRIz light curves of 51 type II supernovae discovered during the course of four different surveys during 1986–2003: the Cerro Tololo Supernova Survey, the Calán/Tololo Supernova Program (C and T), the Supernova Optical and Infrared Survey (SOIRS), and the Carnegie Type II Supernova Survey (CATS). The photometry is based on template-subtracted images to eliminate any potential host galaxy light contamination, and calibrated from foreground stars. This work presents these photometric data, studies the color evolution using different bands, and explores the relation between the magnitude at maximum brightness and the brightness decline parameter (s) from maximum light through the end of the recombination phase. This parameter is found to be shallower for redder bands and appears to have the best correlation in the B band. In addition, it also correlates with the plateau duration, being shorter (longer) for larger (smaller) s values

    We present a unified description of the low-energy limits of type-II string theories. This is achieved by a formulation that doubles the space-time coordinates in order to realize the T-duality group O(10,10) geometrically. The Ramond-Ramond fields are described by a spinor of O(10,10), which couples to the gravitational fields via the Spin(10,10) representative of the so-called generalized metric. This theory, which is supplemented by a T-duality covariant self-duality constraint, unifies the type-II theories in that each of them is obtained for a particular subspace of the doubled space. © 2011 American Physical Society

    The theory of the ultrasound propagation in the mixed state of type-II superconductors is suggested which takes into account the Magnus force on vortices, the anti-Magnus force on ions, and diamagnetism of the mixed state. The acoustic Faraday effect (rotation of polarization of the transverse ultrasonic wave propagating along vortices) is shown to be linear in the Magnus force in any regime of the flux flow for wavelengths used in the ultrasound experiments now. Therefore, in contrast to pre...

    We propose a Standard Model extension with underlying A4 flavour symmetry where small Dirac neutrino masses arise from a Type-II seesaw mechanism. The model predicts the "golden" flavour-dependent bottom-tau mass relation, requires an inverted neutrino mass ordering and non-maximal atmospheric mixing angle. Using the latest neutrino oscillation global fit [1] we derive restrictions on the oscillation parameters, such as a correlation between δCP and mνlightest.

    To explore the feasibility and safety of type II binding pancreaticogastrostomy (BPG) in pancreaticoduodenectomy and mid-segmentectomy of pancreas. From November 2008 to May 2009, 26 patients underwent pancreaticoduodenectomy and mid-segmentectomy of pancreas with type II BPG reconstruction, including 13 cases of pancreatic head cancer, 3 cases of duodenal adenocarcinoma, 2 cases of ampullary carcinoma, 4 cases of cholangiocarcinoma, 1 case of bile duct cell severe atypical hyperplasia, and 1 case of stomach cancer. The process of type II BPG was described as the following: after pancreas remnant was mobilized for 2-3 cm, a piece of sero-muscular layer at the posterior gastric wall was excised and then a sero-muscular depth purse-suturing with 3-0 prolene was pre-placed (outer purse-string). Incising anterior gastric wall or opening part of the closed distal gastric stump, the mucosa layer at the sero-muscular defect was incised and then purse-suture at the mucosal tube was pre-placed (inner purse-string). Through the two pre-placed purse-strings, the pancreas remnant was pulled into the gastric lumen and then posterior gastric wall was pushed backward to keep it closely in contact with the retro-peritoneal wall. Thereafter, the outer purse-string was tied (outer binding) and then the inner purse-string was tied (inner binding). All cases underwent BPG of type II. The operative time ranged from 3 to 5.5 hours. The postoperative hospital stay ranged from 6 to 48 days. Postoperative complications included 1 case of ascites, 2 cases of delayed gastric emptying and 1 case of intra-abdominal bleeding. All cases with complications were cured after nonsurgical treatment. No mortality or pancreatic leakage occurred. Pancreaticogastrostomy is good for accommodating a large pancreas stump. Binding technique is very helpful in minimizing the leak rate of pancreaticogastrostomy. While type I BPG is safe and easy to perform, type II is even safer and easier to be done.

    Laryngeal cleft (LC) is a rare congenital anomaly manifesting in a variety of symptoms, including swallowing disorders and aspirations, dyspnea, stridor and hoarseness. The mild forms (types I-II) may be underdiagnosed, leading to protracted symptomatology and morbidity. To evaluate the diagnostic process, clinical course, management and outcome in children with type I-II laryngeal clefts. We conducted a retrospective case analysis for the years 2005-2012 in a tertiary referral center. Seven children were reviewed: five boys and two girls ranging in age from birth to 5 years. The most common presenting symptoms were cough, aspirations and pneumonia. Evaluation procedures included fiber-optic laryngoscopy (FOL), direct laryngoscopy (DL) and videofluoroscopy. Other pathologies were seen in three children. Six children underwent successful endoscopic surgery and one child was treated conservatively. The postoperative clinical course was uneventful in most of the cases. Types I-II LC should be considered in the differential diagnosis of children presenting with protracted cough and aspirations. DL is crucial for establishing the diagnosis. Endoscopic surgery is safe and should be applied promptly when conservative measures fail.

    The most common hematologic complication of inflammatory bowel disease (IBD)--ulcerative colitis and Crohn's Disease is anemia. Anemia in patients with IBD may be a result of iron, vitamin B12 or folate deficiency; anemia of chronic disease and hemolytic anemia are other causes in these patients. Factors contributing to the development of anemia include chronic gastrointestinal blood loss, vitamin B12 malabsorption secondary to terminal ileitis, folate deficiency as a result of sulfasalazine therapy. Approximately 30% of patients with IBD have hemoglobin levels below 12 g/dl. The risk of developing anemia relates to disease activity, given that blood loss and inflammatory anemia are triggered by intestinal inflammation. In the management strategy of IBD patients with anemia it is important to distinguish between the different types of anemia in order to decide an appropriate manner of treatment.

    We report a new case of osteogenesis imperfecta (OI) type II which is a perinatal lethal form. First trimester ultrasound didn't identified abnormalities. Second trimester ultrasound showed incurved limbs, narrow chest, with hypomineralization and multiple fractures of ribs and long bones. Parents refused pregnancy termination; they felt that the diagnosis was late. At birth, the newborn presented immediate respiratory distress. Postnatal examination and bone radiography confirmed the diagnosis of OI type IIA. Death occurred on day 25 of life related to respiratory failure.

    This article continues the series of Surveys and Summaries on restriction endonucleases (REases) begun this year in Nucleic Acids Research. Here we discuss ‘Type II’ REases, the kind used for DNA analysis and cloning. We focus on their biochemistry: what they are, what they do, and how they do it. Type II REases are produced by prokaryotes to combat bacteriophages. With extreme accuracy, each recognizes a particular sequence in double-stranded DNA and cleaves at a fixed position within or nea...

    Full Text Available Background: Iron-deficiency anaemia is a major global public health problem affecting all stages of life cycle. Adolescent boys are also vulnerable to it owing to their growth spurt and inadequate dietary intakes. Assessment of anaemia and quantification of the burden of iron-deficiency anemia in them has been less studied. Knowledge of these aspects at the local level may help public health functionaries take appropriate decisions. Objectives: i To assess the magnitude and severity of anaemia in adolescent boys residing in a peri-urban community of Delhi, ii To identify the clinico-pathological type of anemia and among adolescent boys residing in a South Delhi locality iii To estimate the burden of iron deficiency in them. Materials and Methods: A Community-based cross sectional study was conducted in 250 adolescent boys at Mehrauli in South Delhi in 2012. Hemoglobin estimation was done by Hemocue method, severity of anaemia assessed as per WHO criteria. To assess the clinico-pathological type of anaemia peripheral smears were prepared and stained with Wright Giemsa stain for assessing red-cell morphology. Serum ferritin estimation by MAb ELISA was done to confirm Iron deficiency. Statistical analysis: SPSS ver 12 and Epi Info ver 7 softwares were used for data entry and analysis. Mean and SD was calculated for quantitative variables while qualitative variables were compared by percentages. Chi-square test and ANOVA was used for checking statistical significance in observed differences. Results: Pallor was seen in 14.6%. Prevalence of anaemia was 16.4% with proportion of mild, moderate and severe anemia being 66.7%, 31.2% and 2.1% respectively. Mean haemoglobin concentration was 13.03 ±1.18 gm% (min 7.6, max 15.0. Anemia prevalence increased with increase in age (9.6%, 18.4% and 26.0% in early, middle and late adolescence, respectively. Clinico-pathological type of anaemia was microcytic-hypochromic in 50.0%, normocytic-normochromic in 17

    Records were reviewed on all patients with mucopolysaccharidosis type II (Hunter syndrome) seen at a single institution from 1999 to 2013 to identify those with a history of neonatal intensive care. Eleven of 34 patients were in a neonatal intensive care unit and all had respiratory distress with 8 diagnoses of respiratory distress syndrome and 3 of transient tachypnea of the newborn. None of the infants were premature; four were delivered by cesarean section. These findings suggest that respiratory distress is more commonly observed in neonates with MPS II than in the general population. This may reflect airway disease already present in this disorder at the time of birth. © 2013.

    Anemia coexists with inflammatory bowel disease (IBD) in up to two-thirds of patients, significantly impairing quality of life. The most common types of anemia in patients with IBD are iron deficiency anemia and anemia of chronic disease, which often overlap. In most cases, available laboratory tests allow successful diagnosis of iron deficiency, where difficulties appear, recently established indices such as soluble transferrin-ferritin ratio or percentage of hypochromic red cells are used. In this review, we discuss the management of the most common types of anemia in respect of the latest available data. Thus, we provide the mechanisms underlying pathophysiology of these entities; furthermore, we discuss the role of hepcidin in developing anemia in IBD. Next, we present the treatment options for each type of anemia and highlight the importance of individual choice of action. We also focus on newly developed intravenous iron preparations and novel, promising drug candidates targeting hepcidin. Concurrently, we talk about difficulties in differentiating between the true and functional iron deficiency, and discuss tools facilitating the process. Finally, we emphasize the importance of proper diagnosis and treatment of anemia in IBD. We conclude that management of anemia in patients with IBD is tricky, and appropriate screening of patients regarding anemia is substantial.

    Plyometric training has been successfully used in different sporting contexts. Studies that investigated the effect of plyometric training on muscle morphology are limited, and results are controversial with regard to which muscle fiber type is mainly affected. To analyze the skeletal muscle structural and ultrastructural change induced by an acute bout of plyometric exercise to determine which type of muscle fibers is predominantly damaged. Descriptive laboratory study. Research laboratory. Eight healthy, untrained individuals (age = 22 ± 1 years, height = 179.2 ± 6.4 cm, weight = 78.9 ± 5.9 kg). Participants completed an acute bout of plyometric exercise (10 sets of 10 squat-jumps with a 1-minute rest between sets). Blood samples were collected 9 days and immediately before and 6 hours and 1, 2, and 3 days after the acute intervention. Muscle samples were collected 9 days before and 3 days after the exercise intervention. Blood samples were analyzed for creatine kinase activity. Muscle biopsies were analyzed for damage using fluorescent and electron transmission microscopy. Creatine kinase activity peaked 1 day after the exercise bout (529.0 ± 317.8 U/L). Immunofluorescence revealed sarcolemmal damage in 155 of 1616 fibers analyzed. Mainly fast-twitch fibers were damaged. Within subgroups, 7.6% of type I fibers, 10.3% of type IIa fibers, and 14.3% of type IIx fibers were damaged as assessed by losses in dystrophin staining. Similar damage was prevalent in IIx and IIa fibers. Electron microscopy revealed clearly distinguishable moderate and severe sarcomere damage, with damage quantifiably predominant in type II muscle fibers of both the glycolytic and oxidative subtypes (86% and 84%, respectively, versus only 27% of slow-twitch fibers). We provide direct evidence that a single bout of plyometric exercise affected mainly type II muscle fibers.

    We study the vacuum stability and perturbativity conditions in the minimal type-II seesaw model. These conditions give characteristic constraints to the model parameters. In the model, there is a SU(2){sub L} triplet scalar field, which could cause a large Higgs mass correction. From the naturalness point of view, heavy Higgs masses should be lower than 350 GeV, which may be testable by the LHC Run-II results. Due to the effects of the triplet scalar field, the branching ratios of the Higgs decay (h → γγ, Zγ) deviate from the standard model, and a large parameter region is excluded by the recent ATLAS and CMS combined analysis of h → γγ. Our result of the signal strength for h → γγ is R{sub γγ}

    The sequence of the beta-subunit of human chorionic gonadotropin (hCGβ) varies depending on whether hCGβ is encoded by type I or type II genes. Type II genes are upregulated in trophoblast and cancer but hCGβ can be detected in the serum of nonpregnant women and healthy individuals. We aimed to determine whether monoclonal antibody (mAb) FBT11-II specifically detects hCGβ encoded by type II genes (type II hCGβ). Competitive inhibition assays with synthetic peptides, immunocytochemical and immunohistochemical studies, type II hCGβ dosing immunoassays and sequencing of CGB genes were performed. Competitive inhibition assays determined that mAb FBT11-II recognizes the type II hCGβ derived peptide. CGB mRNA sequencing of JEG-3 (trophoblastic) and T24 (bladder) cell lines confirmed that JEG-3 expresses type II genes while T24 expresses exclusively type I. FBT11-II only recognizes JEG-expressed hCGβ. Placenta immunohistochemical studies confirmed that type II hCGβ expression is restricted to the syncytiotrophoblast. Immunoassays detected type II hCGβ in serum of patients with either nontrophoblastic cancers or fetal Down syndrome. Type II gene expression can be detected using FBT11-II. This specific recognition could improve the clinical usefulness of assays aimed at either managing aggressive tumors or screening for Down syndrome. Copyright © 2015. Published by Elsevier B.V.

    Full Text Available Abstract: This study aimed to investigate a possible relationship between alveolar type II cells and the inflammatory response to infection with Leptospira spp., and thus comprise a further element that can be involved in the pathogenesis of lung injury in naturally infected pigs. The study group consisted of 73 adult pigs that were extensively reared and slaughtered in Teresina, Piauí state, and Timon, Maranhão state, Brazil. The diagnosis of leptospirosis was made using the microscopic agglutination test (MAT aided by immunohistochemistry and polymerase chain reaction. The MAT registered the occurrence of anti-Leptospira antibodies in 10.96% (8/73 of the pigs. Immunohistochemistry allowed for the visualization of the Leptospira spp. antigen in the lungs of 87.67% (64/73 of the pigs. There was hyperplasia of bronchus-associated lymphoid tissue and circulatory changes, such as congestion of alveolar septa, parenchymal hemorrhage and edema within the alveoli. Lung inflammation was more intense (p = 0.0312 in infected animals, which also showed increased thickening of the alveolar septa (p = 0.0006. Evaluation of alveolar type II (ATII cells using an anti-TTF-1 (Thyroid Transcription Factor-1 antibody showed that there were more immunostained cells in the non-infected pigs (53.8% than in the infected animals (46.2% and that there was an inverse correlation between TTF-1 positive cells and the inflammatory infiltrate. There was no amplification of Leptospira DNA in the lung samples, but leptospiral DNA amplification was observed in the kidneys. The results of this study showed that a relationship exists between a decrease in alveolar type II cells and a leptospire infection. Thus, this work points to the importance of studying the ATII cells as a potential marker of the level of lung innate immune response during leptospirosis in pigs.

    Type II diabetes mellitus causes metabolic changes that may lead to early menopause and worsen climacteric symptoms. To determine the risk factors for type II diabetes mellitus and assess the impact of this disease on the age of menopause and on climacteric symptoms. A total of 6079 women aged between 40 and 59 years from 11 Latin American countries were requested to answer the Menopause Rating Scale and Goldberg Anxiety-Depression Scale. The prevalence of diabetes was 6.7%. Diabetes mellitus was associated with arterial hypertension (odds ratio (OR) 4.49; 95% confidence interval (CI) 3.47-5.31), the use of psychotropic drugs (OR 1.54; 95% CI 1.22-1.94), hormonal therapy (OR 1.46; 95% CI 1.11-1.92), ≥ 50 years of age (OR 1.48; 95% CI 1.17-1.86), overweight or obese (OR 1.47; 95% CI 1.15-1.89), and waist circumference ≥ 88 cm (OR 1.32; 95% CI 1.06-1.65). Factors associated with lower risk of diabetes were the use of hormonal contraceptives (OR 0.55; 95% CI 0.35-0.87), alcohol (OR 0.73; 95% CI 0.54-0.98) and living in cities > 2500 meters above sea level (OR 0.70; 95% CI 0.53-0.91) or with high temperatures (OR 0.67; 95% CI 0.51-0.88). In turn, diabetes tripled the risk of menopause in women under 45 years of age. Diabetes did not increase the risk of deterioration of quality of life due to climacteric symptoms. Menopause does not increase the risk of type II diabetes mellitus. Diabetes is associated with early menopause in women under 45 years of age.

    Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease that presents with sicca symptoms of the main mucosal surfaces. Patients with pSS have a broad spectrum of laboratory features, such as cytopenias and hypergammaglobulinemia. Although hematological abnormalities are usually seen in pSS patients, agranulocytosis and autoimmune hemolytic anemia (AIHA) are rare. Here we describe a 40-year-old woman with pSS who developed both agranulocytosis and mixed-type AIHA. An increased risk of malignancies has also been reported in pSS patients with hematological changes. Although there is no evidence of malignancies, this patient should be closely followed up in case of developing lymphoma. © 2015 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

    2013-01-01

    We outline the construction of type II superstring field theory leading to a geometric and algebraic BV master equation, analogous to Zwiebach's construction for the bosonic string. The construction uses the small Hilbert space. Elementary vertices of the non-polynomial action are described with the help of a properly formulated minimal area problem. They give rise to an infinite tower of superstring field products defining a $\\mathcal{N}=1$ generalization of a loop homotopy Lie algebra, the genus zero part generalizing a homotopy Lie algebra. Finally, we give an operadic interpretation of the construction.

    The continuum spectral energy distribution of the flux emerging from type II supernovae is calculated from quasi-static radiative transfer through a power-law density gradient, assuming radiative equilibrium and LTE. It is found that the Balmer jump disappears at high effective temperatures and low densities, while the spectrum resembles that of a dilute blackbody but is flatter with a sharper cutoff at the short-wavelength end. A significant UV excess is found in all models calculated. The calculation should be considered exploratory because of significant effects which are anticipated to arise from departure from LTE.

    The endodontic treatment of teeth with dens invaginatus, characterized by an infolding of enamel and dentin, extending deep into the pulp cavity near the root apex, may be complicated and challenging. The complexity of the internal anatomy may create challenges for the complete removal of diseased pulpal tissue and the subsequent sealing of the canal system. Because of the bizarre root canal anatomy and widely open apex, a combination of nonsurgical and surgical endodontic treatment or extraction is the most common choice of therapy. This article describes case reports of nonsurgical endodontic treatment of Type II dens invaginatus associated with periradicular lesion. PMID:20617071

    Most patients with epithelial ovarian cancer achieve a complete clinical remission (CCR) with normal CA-125 but will still relapse and die from their disease. The present study was designed to determine whether CA-125 levels before, during, and after primary treatment provide prognostic information for both type I and type II ovarian cancer. In this retrospective study, we identified 410 patients with epithelial ovarian cancer who had achieved a CCR between 1984 and 2011. A Cox proportional hazards model and log-rank test were used to assess associations between the nadir CA-125, histotype, and prognosis. The baseline serum CA-125 concentration was higher in patients with type II ovarian cancer than in those with type I ovarian cancer (P CA-125 was an independent predictor of progression-free survival (PFS; P CA-125 of 10 U/mL or less and 13.6 and 64.6 months in those with CA-125 of 11 to 35 U/mL, respectively (P = 0.01 and P = 0.002, respectively). Histotype was an independent predictor of PFS (P = 0.041): the PFS and OS durations of the patients with type I ovarian cancer were longer than those of the patients with type II ovarian cancer (P CA-125 and histotype are predictive of PFS and OS durations in patients with ovarian cancers who experienced a CCR. Progression-free survival and OS durations were shorter in the patients with CA-125 levels of 11 to 35 U/mL and type II disease than in those with CA-125 levels of 10 U/mL or less and type I ovarian cancer.

  3. The type II collagen fragments Helix-II and CTX-II reveal different enzymatic pathways of human cartilage collagen degradation

    OBJECTIVE: Cartilage degradation in osteoarthritis (OA) generates the type II collagen fragments, Helix-II and CTX-II that can be used as clinical biological markers. Helix-II and C-telopeptide of type II collagen (CTX-II) levels are associated independently with progression of OA suggesting...... that they may be generated through different collagenolytic pathways. In this study we analyzed the release of Helix-II and CTX-II from human cartilage collagen by the proteinases reported to play a role in cartilage degradation. METHODS: In vitro, human articular cartilage extract was incubated with activated...... pathways. Helix-II and CTX-II alone reflect only partially overall cartilage collagen degradation. These findings may explain why these two biological markers could provide complementary information on disease progression in OA....

    Anemia of any degree is recognized as a significant independent contributor to morbidity, mortality, and frailty in elderly patients. Among the broad types of anemia in the elderly a peculiar role seems to be played by the anemia associated with chronic inflammation, which remains the most complex form of anemia to treat. The origin of this nonspecific inflammation in the elderly has not yet been clarified. It seems more plausible that the oxidative stress that accompanies ageing is the real ...

    Full Text Available A series of new bimetallic transition metal complexes of the type [Cu(pn2] [MCl4] have been synthesized (where M = Co(II, Ni(II, Cu(II, Zn(II, Cd(II and Hg(II, pn = 1,3-diaminopropane and characterized by elemental analysis, molar conductance, TGA, IR and electronic spectra. All the compounds are 1:1 electrolyte in DMF. The Cu(II ion is square-planar while metal ions in the anionic moiety acquire their usual tetrahedral arrangement. On the basis of these studies it is concluded that anionic moiety is electrically stabilized by its cationic counterpart.

    The lungs face the immunologic challenge of rapidly eliminating inhaled pathogens while maintaining tolerance to innocuous Ags. A break in this immune homeostasis may result in pulmonary inflammatory diseases, such as allergies or asthma. The observation that alveolar epithelial type II cells (Type...... II) constitutively express the class II MHC led us to hypothesize that Type II cells play a role in the adaptive immune response. Because Type II cells do not express detectable levels of the costimulatory molecules CD80 and CD86, we propose that Type II cells suppress activation of naive T cells...

  9. [Immune pathophysiology of refractory anemias].

    Among different immune pathophysiologies of anemia, those of bone marrow failure syndromes such as aplastic anemia and myelodysplastic syndrome are most difficult to understand. An increase in the proportion of glycosylphosphatidyl-inositol anchored protein-deficient cells has been identified as the best marker for the presence of immune pathophysiology in this elusive syndrome. The significance of detecting small populations of such paroxysmal nocturnal hemoglobinuria (PNH)-type cells was substantiated by a recent observation that PNH-type cells arose from a donor-derived hematopoietic stem cell with a PIG-A mutation in an aplastic anemia patient with late graft failure which responded well to immunosuppressive therapy. Identification of auto-antigens capable of inducing cytotoxic T cells against hematopoietic stem cells is necessary to prove the escape of PIG-A mutant clone from the immune system attack using animal models.

    Full Text Available A 45-year-old female was diagnosed with Hashimoto’s thyroiditis in 1976 and Addison’s disease in 1979. At that time, her antimitochondrial antibody (AMA level was elevated at 1:32. She subsequently developed premature ovarian failure and type I diabetes mellitus. In 1996, she became jaundiced with a cholestatic enzyme pattern. AMA was positive at a titre of 1:256. A liver biopsy confirmed the diagnosis of primary biliary cirrhosis (PBC. She underwent a liver transplantation in January 1998. This is the first report of PBC in association with type II autoimmune polyglandular syndrome. The association of PBC with other organ-specific autoimmune diseases supports an immune-mediated pathogenesis and may have implications in further studies of PBC.

  13. Flux-flow noise in type II superconductors

    Choe, H.M.; Ziel, A. van der

    1976-01-01

    This paper discusses flux-flow noise in type II superconductors. A theoretical expression is given for flux-flow noise in a rectangular sample with two probes, and compared with earlier models; the differences are not very large. Experiments give no flicker noise below 20 μW/mm 2 dissipation at 4.2 K, whereas much larger dissipations can be tolerated below the lambda temperature before flicker noise sets in. The shape of the spectrum at elevated frequencies is of the 1/f type, as predicted by the theory, followed by a probe size effect at still higher frequencies. The noise is much larger than would be expected from single fluxoids; this is caused by the flux bundle effect which, in turn, is due to pinning and fluxoid interaction. The size of the flux bundles can be determined from the data, it decreases with increasing current. (Auth.)

  14. Exotic dual of type II double field theory

    2017-04-01

    Full Text Available We perform an exotic dualization of the Ramond–Ramond fields in type II double field theory, in which they are encoded in a Majorana–Weyl spinor of O(D,D. Starting from a first-order master action, the dual theory in terms of a tensor–spinor of O(D,D is determined. This tensor–spinor is subject to an exotic version of the (self-duality constraint needed for a democratic formulation. We show that in components, reducing O(D,D to GL(D, one obtains the expected exotically dual theory in terms of mixed Young tableaux fields. To this end, we generalize exotic dualizations to self-dual fields, such as the 4-form in type IIB string theory.

    1981-06-01

    hereditary anemias of mice have been the chief objects of investigation. At present under study are four macrocytic anemias, five hemolytic anemias, nonhemolytic microcytic anemia, transitory siderocytic anemia, sex-linked iron-transport anemia, an α-thalassemia, and a new target-cell anemia. Each of these blood dyscrasias is caused by the action of a unique mutant gene, which determines the structure of different intracellular molecules, and thus controls a different metabolic process. Thus our wide range of different hereditary anemias has considerable potential for uncovering many different aspects of hemopoietic homeostatic mechanisms in the mouse. Each anemia is studied through: (a) characterization of peripheral blood values, (b) determinations of radiosensitivity under a variety of conditions, (c) measurements of iron metabolism and heme synthesis, (d) histological and biochemical study of blood-forming tissue, (e) functional tests of the stem cell component, (f) examination of responses to erythroid stimuli, and (g) transplantation of tissue between individuals of differently affected genotypes

  16. Gravitational Field Shielding by Scalar Field and Type II Superconductors

    Directory of Open Access Journals (Sweden)

    Zhang B. J.

    2013-01-01

    Full Text Available The gravitational field shielding by scalar field and type II superconductors are theoret- ically investigated. In accord with the well-developed five-dimensional fully covariant Kaluza-Klein theory with a scalar field, which unifies the Einsteinian general relativity and Maxwellian electromagnetic theory, the scalar field cannot only polarize the space as shown previously, but also flatten the space as indicated recently. The polariza- tion of space decreases the electromagnetic field by increasing the equivalent vacuum permittivity constant, while the flattening of space decreases the gravitational field by decreasing the equivalent gravitational constant. In other words, the scalar field can be also employed to shield the gravitational field. A strong scalar field significantly shield the gravitational field by largely decreasing the equivalent gravitational constant. According to the theory of gravitational field shielding by scalar field, the weight loss experimentally detected for a sample near a rotating ceramic disk at very low tempera- ture can be explained as the shielding of the Earth gravitational field by the Ginzburg- Landau scalar field, which is produced by the type II superconductors. The significant shielding of gravitational field by scalar field produced by superconductors may lead to a new spaceflight technology in future.

  17. The black hole interior and the type II Weyl fermions

    Zubkov, M. A.

    2018-03-01

    It was proposed recently that the black hole may undergo a transition to the state, where inside the horizon the Fermi surface is formed that reveals an analogy with the recently discovered type II Weyl semimetals. In this scenario, the low energy effective theory outside of the horizon is the Standard Model, which describes excitations that reside near a certain point P(0) in momentum space of the hypothetical unified theory. Inside the horizon the low energy physics is due to the excitations that reside at the points in momentum space close to the Fermi surface. We argue that those points may be essentially distant from P(0) and, therefore, inside the black hole the quantum states are involved in the low energy dynamics that are not described by the Standard Model. We analyze the consequences of this observation for the physics of the black holes and present the model based on the direct analogy with the type II Weyl semimetals, which illustrates this pattern.

    Aim: The aim of this work the report of one case with vitamin D-dependent rickets, type II. Methods: Diagnosis has been established based on anamnesis, physical examination, laboratory findings and radiological examination. Results: A female child (age 25 months) has been hospitalized due to bone deformity, bone pain, alopecia and walking difficulties. The laboratory findings have revealed that the calcium values was low (1.20 mmol/L), phosphates in the reference value (1.30 mmol/L) the alkaline phosphatase value was quite high (852 IU/L), high value of parathyroid hormone (9.21 pmol/L), normal value of 25- hydroxyvitamin D, whereas the values of 1,25-dihydroxyvitamin D was high (185 μmol/L). Radiographic changes were evident and typical in the distal metaphysis of radius and ulna as well as in the bones of lower limbs (distal metaphysis of femur and proximal metaphysis of tibia and fibula). After treatment with calcium and calcitriol, the above mentioned clinical manifestations, laboratory test values and the radiographic changes in bones withdrew. Conclusions: Vitamin D-dependent rickets, type II is a rare genetic recessive disease, and its treatment includes a constant use of calcium and calcitriol. PMID:24757409

    Presbycusis – age-related hearing loss – is the number one communicative disorder and a significant chronic medical condition of the aged. Little is known about how type II diabetes, another prevalent age-related medical condition, and presbycusis interact. The present investigation aimed to comprehensively characterize the nature of hearing impairment in aged type II diabetics. Hearing tests measuring both peripheral (cochlea) and central (brainstem and cortex) auditory processing were utilized. The majority of differences between the hearing abilities of the aged diabetics and their age-matched controls were found in measures of inner ear function. For example, large differences were found in pure-tone audiograms, wideband noise and speech reception thresholds, and otoacoustic emissions. The greatest deficits tended to be at low frequencies. In addition, there was a strong tendency for diabetes to affect the right ear more than the left. One possible interpretation is that as one develops presbycusis, the right ear advantage is lost, and this decline is accelerated by diabetes. In contrast, auditory processing tests that measure both peripheral and central processing showed fewer declines between the elderly diabetics and the control group. Consequences of elevated blood sugar levels as possible underlying physiological mechanisms for the hearing loss are discussed. PMID:16309862

    Feline infectious peritonitis virus (FIPV) and feline enteric coronavirus (FECV) are two important coronaviruses of domestic cat worldwide. Although FCoV is prevalent among cats; the fastidious nature of type I FCoV to grow on cell culture has limited further studies on tissue tropism and pathogenesis of FCoV. While several studies reported serological evidence for FCoV in Malaysia, neither the circulating FCoV isolated nor its biotypes determined. This study for the first time, describes the isolation and biotypes determination of type I and type II FCoV from naturally infected cats in Malaysia. Of the total number of cats sampled, 95% (40/42) were RT-PCR positive for FCoV. Inoculation of clinical samples into Crandell feline kidney cells (CrFK), and Feline catus whole fetus-4 cells (Fcwf-4), show cytopathic effect (CPE) characterized by syncytial cells formation and later cell detachment. Differentiation of FCoV biotypes using RT-PCR assay revealed that, 97.5% and 2.5% of local isolates were type I and type II FCoV, respectively. These isolates had high sequence homology and phylogenetic similarity with several FCoV isolates from Europe, South East Asia and USA. This study reported the successful isolation of local type I and type II FCoV evident with formation of cytopathic effects in two types of cell cultures namely the CrFK and Fcwf-4 , where the later cells being more permissive. However, the RT-PCR assay is more sensitive in detecting the antigen in suspected samples as compared to virus isolation in cell culture. The present study indicated that type I FCoV is more prevalent among cats in Malaysia.

    In this work we present a preliminary investigation by means of neutron diffraction experiment to determine the residual stress state in three different iron meteorites (Chinga, Sikhote Alin and Nantan). Because of the very peculiar microstructural characteristic of this class of samples, all the systematic effects related to the measuring procedure - such as crystallite size and composition - were taken into account and a clear differentiation in the statistical distribution of residual stress in coarse and fine grained meteorites were highlighted. Moreover, the residual stress state was statistically analysed in three orthogonal directions finding evidence of the existence of both type I and type II residual stress components. Finally, the application of von Mises approach allowed to determine the distribution of type II stress.

    It has long been speculated that there is a connection between supernova impostors and Type II-n supernovae. The modern Type II-n spectroscopic classification overlaps a great deal with Zwicky’s “Type V” supernovae, which includes several impostors. In late 2012, SN 2009ip, a known impostor, may have exploded as a Type II-n supernova. The decline from that event exhibited unusual fluctuations in brightness that are not evident in other Type II-n light curves. We present the light curves of several more recent Type II-n supernova and compare them with other published samples.

    The frequency of anemia associated with primary hyperparathyroidism is uncertain. When anemia does occur, its mechanisms are obscure. Two patients with primary hyperparathyroidism and moderate normochromic, normocytic, reticulocytopenic anemia were studied in detail. Both had results of ferrokinetic studies that were consistent with the anemia of chronic disease; one had low serum iron concentrations and reduced normoblastic iron incorporation. Anemia in both patients resolved after parathyroidectomy. Clinical records of 100 nonuremic patients with primary hyperparathyroidism were reviewed and three other anemic patients were found. The cause of anemia in two of these individuals was bleeding in the upper gastrointestinal system, and the third had folate deficiency attributable to chronic alchoholism.

  5. Metallicity from Type II supernovae from the (i)PTF

    Type IIP supernovae (SNe IIP) have recently been proposed as metallicity (Z) probes. The spectral models of Dessart et al. (2014, MNRAS, 440, 1856) showed that the pseudo-equivalent width of Fe ii λ5018 (pEW 5018 ) during the plateau phase depends on the primordial Z, but there was a paucity of SNe IIP exhibiting pEW 5018 that were compatible with Z < 0.4 Z ⊙ . This lack might be due to some physical property of the SN II population or to the fact that those SNe have been discovered in luminous, metal-rich targeted galaxies. In this paper, we use SN II observations from the untargeted (intermediate) Palomar Transient Factory [(i)PTF] survey, aiming to investigate the pEW 5018 distribution of this SN population and, in particular, to look for the presence of SNe II at lower Z. We perform pEW 5018 measurements on the spectra of a sample of 39 (i)PTF SNe II, selected to have well-constrained explosion epochs and light-curve properties. Based on the comparison with the pEW 5018 spectral models, we subgrouped our SNe into four Z bins from Z ≈ 0.1 Z ⊙ up to Z ≈ 2 Z ⊙ . We also independently investigated the Z of the hosts by using their absolute magnitudes and colors and, in a few cases, using strong-line diagnostics from spectra. We searched for possible correlations between SN observables, such as their peak magnitudes and the Z inferred from pEW 5018 . We found 11 events with pEW 5018 that were small enough to indicate Z ≈ 0.1 Z ⊙ . The trend of pEW 5018 with Z matches the Z estimates obtained from the host-galaxy photometry, although the significance of the correlation is weak. Finally, we also found that SNe with brighter peak magnitudes have smaller pEW 5018 and occur at lower Z.

  6. Magnetoexcitons in type-II semiconductor quantum dots

    2004-03-01

    We present a theoretical investigation of excitons in type-II semiconductor quantum dots (QD). In these systems the confinement of electrons inside the QD and the hole outside the QD produces a ring-like structure [1-2]. Recently, Ribeiro et al [3], in a magnetophotoluminescence study of type-II InP/GaAs self-assembled quantum dots, observed Aharonov-Bohm-type oscillations characteristic of the ring topology for neutral excitons. Using a simple model they have derived the groundstate hole energy as a function of the magnetic field, and obtained values for the ring parameters which are in good agreement with the measured values. However, some of the features observed experimentally, in the photoluminescence intensity, can not be well explained under that approach. In this work we present a more realistic model which considers the finite width of the ring and the electron-hole interaction included via a perturbative approach. The calculations are performed within the oneparticle formalism using the effective mass approximation. The confinement potential for electrons is modelled as the superposition of a quantum well potential along the axial direction, and a parabolic lateral confinement potential. The energies for the hole in the ring plane are calculated using the method of reference [4]. Theoretical calculations are in good agreement with the experimental results of reference [3] provided that excitonic effects are properly taken into account. References 1. A.O.

    Cerebral vasculopathy in sickle cell anemia (SCA) begins in childhood and features intracranial arterial stenosis with high risk of ischemic stroke. Stroke risk can be reduced by transcranial doppler (TCD) screening and chronic transfusion therapy; however, this approach is impractical in many developing countries. Accumulating evidence supports the use of hydroxyurea for the prevention and treatment of cerebrovascular disease in children with SCA. Recently we reported that hydroxyurea significantly reduced the conversion from conditional TCD velocities to abnormal velocities; whether hydroxyurea can be used for children with newly diagnosed severe cerebrovascular disease in place of starting transfusion therapy remains unknown. The primary objective of the EXpanding Treatment for Existing Neurological Disease (EXTEND) trial is to investigate the effect of open label hydroxyurea on the maximum time-averaged mean velocity (TAMV) after 18 months of treatment compared to the pre-treatment value. Secondary objectives include the effects of hydroxyurea on serial TCD velocities, the incidence of neurological and non-neurological events, quality of life (QOL), body composition and metabolism, toxicity and treatment response, changes to brain magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA), genetic and serologic markers of disease severity, and cognitive and pulmonary function. This prospective Phase II trial will enroll children with SCA in Jamaica, between the ages of 2 and 17 years, with either conditional (170-199 cm/sec) or abnormal (≥ 200 cm/sec) TCD velocities. Oral hydroxyurea will be administered daily and escalated to the maximum tolerated dose (MTD). Participants will be seen in the Sickle Cell Unit (SCU) in Kingston, Jamaica monthly until achieving MTD, and then every 3 months. TCD will be performed every 6 months. Currently, 43 participants have been enrolled out of a projected 50. There was one withdrawal due to immigration, with

    Full Text Available Estimated incidence of Crigler-Najjar syndrome(CNS is 1 case per 1,000,000 births(1 million. The overall prevalence of CN syndrome is unknown, with only several hundred people reported to have this disease. It is interestingly very rare to encounter a pregnant adult women with congenital jaundice. Pregnancy in CN type II patients is a diagnostic and a therapeutic challenge because of the high risk of bilirubin encephalopathy with serious neurological damage as life-threatening complications for the fetus. To date 8 pregnancy outcome have been reported from 5 women and we report the6 woman with a successful 9 th pregnancy outcome. We have discussed detail history, presentation and management during pregnancy and care of the new born.

  4. Distribution of magnetic field in type II superconductors

    Castro, J.L. de.

    1986-09-01

    The magnetie field penetration profile, in type II superconductor, has studied in specially designed cylindrical samples. The samples consist of alternated thick layers ( > 30 μm ) of niobium and copper deposited, by electron-beam evaporation or electro-chemical deposition, on cylindric core of either niobium or copper. The magnetization curves, the magnetic susceptibility and the differential susceptibility for small hysteresis loop ( H c1 c2 ) were measured for all the samples between 4. 2 and 9.5 K. These measurements, done with flux pinned and without, show some peculiar descontinuities and inflections which seems to resemble the samples shape. A simple phenonenological extension of Bean's critical state model was applied to these results, giving a resonable qualitative agreement. Also, a more elaborated theoretical model was improve which could give more quantitative fitting. (author) [pt

  5. Neutrinos from Choked Jets Accompanied by Type-II Supernovae

    2018-04-01

    The origin of the IceCube neutrinos is still an open question. Upper limits from diffuse gamma-ray observations suggest that the neutrino sources are either distant or hidden from gamma-ray observations. It is possible that the neutrinos are produced in jets that are formed in core-collapsing massive stars and fail to break out, the so-called choked jets. We study neutrinos from the jets choked in the hydrogen envelopes of red supergiant stars. Fast photo-meson cooling softens the neutrino spectrum, making it hard to explain the PeV neutrinos observed by IceCube in a one-component scenario, but a two-component model can explain the spectrum. Furthermore, we predict that a newly born jet-driven type-II supernova may be observed to be associated with a neutrino burst detected by IceCube.

    Full Text Available The paper gives the data available in the literature, which reflect the manifestations, diagnosis, and current treatments of the rare (orphan inherited disease glycogen storage disease type II or Pomp disease in children, as well as its classification. The infant form is shown to be most severe, resulting in death from cardiovascular or pulmonary failure generally within the first year of a child’s life. Emphasis is laid on major difficulties in the differential and true diagnosis of this severe disease. Much attention is given to the new pathogenetic treatment — genetically engineered enzyme replacement drug Myozyme®. The authors describe their clinical case of a child with the juvenile form of glycogen storage disease type II (late-onset Pompe disease. Particular emphasis is laid on the clinical symptoms of the disease and its diagnostic methods, among which the morphological analysis of a muscle biopsy specimen by light and electron microscopies, and enzyme and DNA diagnoses are of most importance. The proband was found to have significant lysosomal glycogen accumulation in the muscle biopsy specimen, reduced lymphocyte acid α-1,4-glucosidase activity to 4,2 nM/mg/h (normal value, 13,0—53,6 nM/mg/h, described in the HGMD missense mutation database from 1000 G>A p.Gly334er of the GAA in homozygous state, which verified the diagnosis of Pompe disease.

    2014-01-01

    NKT cells are CD1d-restricted T cells that recognize lipid antigens. They also have been shown to play critical roles in the regulation of immune responses. In the immune responses against tumors, two subsets of NKT cells, type I and type II, play opposing roles and cross-regulate each other. As members of both the innate and adaptive immune systems, which form a network of multiple components, they also interact with other immune components. Here we discuss the function of NKT cells in tumor immunity and their interaction with other regulatory cells, especially CD4+CD25+Foxp3+ regulatory T cells. PMID:24384834

    OBJECTIVE: To investigate the prognostic significance of dividing epithelial ovarian cancer (EOC) in type I and type II tumors based on pathologic variables. METHODS: We used the Danish Gynecologic Cancer Database to identify all patients diagnosed with EOC from 2005 to 2012. Information...... on histologic type and grade were used to classify tumors as either type I or type II. Death, and several prognostic factors were used in the multivariate Cox regression, and Landmark analysis was used to estimate hazard ratios of all-cause mortality. RESULTS: Among 2660 patients diagnosed with EOC, 735 were...... categorized as type I tumors, and 1925 as type II tumors. Patients with type II EOC were more frequently diagnosed in late FIGO stages (stages III-IV) than patients with type I EOC (78.1% vs. 32.1% respectively; P

  19. Molecular determinants on the insect sodium channel for the specific action of type II pyrethroid insecticides

    Pyrethroid insecticides are classified as type I or type II based on their distinct symptomology and effects on sodium channel gating. Structurally, type II pyrethroids possess an α-cyano group at the phenylbenzyl alcohol position, which is lacking in type I pyrethroids. Both type I and type II pyrethroids inhibit deactivation consequently prolonging the opening of sodium channels. However, type II pyrethroids inhibit the deactivation of sodium channels to a greater extent than type I pyrethroids inducing much slower decaying of tail currents upon repolarization. The molecular basis of type II-specific action, however, is not known. Here we report the identification of a residue G1111 and two positively charged lysines immediately downstream of G1111 in the intracellular linker connecting domains II and III of the cockroach sodium channel that are specifically involved in the action of type II pyrethroids, but not in the action of type I pyrethroids. Deletion of G1111, a consequence of alternative splicing, reduced the sodium channel sensitivity to type II pyrethroids, but had no effect on channel sensitivity to type I pyrethroids. Interestingly, charge neutralization or charge reversal of two positively charged lysines (Ks) downstream of G1111 had a similar effect. These results provide the molecular insight into the type II-specific interaction of pyrethroids with the sodium channel at the molecular level. PMID:19022275

    2015-03-01

    In veterinary medicine, anemia without an appropriate compensatory hematopoietic response is termed nonregenerative. Nonregenerative anemia is a common clinical entity, occurring as a result of diminished or ineffective erythropoiesis in association with many types of pathology. This article reviews nonregenerative anemia in domestic animals, emphasizing mechanisms of disease, and also covers other conditions associated with nonregenerative anemia in people. Many aspects of nonregenerative anemia in animals are worthy of further investigation, from molecular mechanisms of disease to epidemiologic impacts. © The Author(s) 2014.

  2. Type-I and type-II topological nodal superconductors with s -wave interaction

    Huang, Beibing; Yang, Xiaosen; Xu, Ning; Gong, Ming

    2018-01-01

    Topological nodal superconductors with protected gapless points in momentum space are generally realized based on unconventional pairings. In this work we propose a minimal model to realize these topological nodal phases with only s -wave interaction. In our model the linear and quadratic spin-orbit couplings along the two orthogonal directions introduce anisotropic effective unconventional pairings in momentum space. This model may support different nodal superconducting phases characterized by either an integer winding number in BDI class or a Z2 index in D class at the particle-hole invariant axes. In the vicinity of the nodal points the effective Hamiltonian can be described by either type-I or type-II Dirac equations, and the Lifshitz transition from type-I nodal phases to type-II nodal phases can be driven by external in-plane magnetic fields. We show that these nodal phases are robust against weak impurities, which only slightly renormalizes the momentum-independent parameters in the impurity-averaged Hamiltonian, thus these phases are possible to be realized in experiments with real semi-Dirac materials. The smoking-gun evidences to verify these phases based on scanning tunneling spectroscopy method are also briefly discussed.

  3. Higgs potential in the type II seesaw model

    The standard model Higgs sector, extended by one weak gauge triplet of scalar fields with a very small vacuum expectation value, is a very promising setting to account for neutrino masses through the so-called type II seesaw mechanism. In this paper we consider the general renormalizable doublet/triplet Higgs potential of this model. We perform a detailed study of its main dynamical features that depend on five dimensionless couplings and two mass parameters after spontaneous symmetry breaking, and highlight the implications for the Higgs phenomenology. In particular, we determine (i) the complete set of tree-level unitarity constraints on the couplings of the potential and (ii) the exact tree-level boundedness from below constraints on these couplings, valid for all directions. When combined, these constraints delineate precisely the theoretically allowed parameter space domain within our perturbative approximation. Among the seven physical Higgs states of this model, the mass of the lighter (heavier) CP even state h 0 (H 0 ) will always satisfy a theoretical upper (lower) bound that is reached for a critical value μ c of μ (the mass parameter controlling triple couplings among the doublet/triplet Higgses). Saturating the unitarity bounds, we find an upper bound m h 0 or approx. μ c and μ c . In the first regime the Higgs sector is typically very heavy, and only h 0 that becomes SM-like could be accessible to the LHC. In contrast, in the second regime, somewhat overlooked in the literature, most of the Higgs sector is light. In particular, the heaviest state H 0 becomes SM-like, the lighter states being the CP odd Higgs, the (doubly) charged Higgses, and a decoupled h 0 , possibly leading to a distinctive phenomenology at the colliders.

    Full Text Available Abstract Background Polymorphisms within the insulin gene can influence insulin expression in the pancreas and especially in the thymus, where self-antigens are processed, shaping the T cell repertoire into selftolerance, a process that protects from β-cell autoimmunity. Methods We investigated the role of the -2221Msp(C/T and -23HphI(A/T polymorphisms within the insulin gene in patients with a monoglandular autoimmune endocrine disease [patients with isolated type 1 diabetes (T1D, n = 317, Addison's disease (AD, n = 107 or Hashimoto's thyroiditis (HT, n = 61], those with a polyglandular autoimmune syndrome type II (combination of T1D and/or AD with HT or GD, n = 62 as well as in healthy controls (HC, n = 275. Results T1D patients carried significantly more often the homozygous genotype "CC" -2221Msp(C/T and "AA" -23HphI(A/T polymorphisms than the HC (78.5% vs. 66.2%, p = 0.0027 and 75.4% vs. 52.4%, p = 3.7 × 10-8, respectively. The distribution of insulin gene polymorphisms did not show significant differences between patients with AD, HT, or APS-II and HC. Conclusion We demonstrate that the allele "C" of the -2221Msp(C/T and "A" -23HphI(A/T insulin gene polymorphisms confer susceptibility to T1D but not to isolated AD, HT or as a part of the APS-II.

  6. [Iron dysregulation and anemias].

    Science.gov (United States)

    Ikuta, Katsuya

    2015-10-01

    Most iron in the body is utilized as a component of hemoglobin that delivers oxygen to the entire body. Under normal conditions, the iron balance is tightly regulated. However, iron dysregulation does occasionally occur; total iron content reductions cause iron deficiency anemia and overexpression of the iron regulatory peptide hepcidin disturbs iron utilization resulting in anemia of chronic disease. Conversely, the presence of anemia may ultimately lead to iron overload; for example, thalassemia, a common hereditary anemia worldwide, often requires transfusion, but long-term transfusions cause iron accumulation that leads to organ damage and other poor outcomes. On the other hand, there is a possibility that iron overload itself can cause anemia; iron chelation therapy for the post-transfusion iron overload observed in myelodysplastic syndrome or aplastic anemia improves dependency on transfusions in some cases. These observations reflect the extremely close relationship between anemias and iron metabolism.

    International Nuclear Information System (INIS)

    Furuse, K.

    1992-01-01

    Recently, an increase in lung cancer incidence has been recognized internationally, and more early stage cases of lung cancer are being detected as a result of improvements in survey and diagnostic techniques, including flexible bronchofiberscope. However, some early stage cases that are inoperable due to age, poor pulmonary function, etc. are generally treated with conventional modalities, such as radiation therapy and/or chemotherapy. Modality to curatively treat such inoperable early stage lung cancers has still not been established. PhotoDynamic Therapy is a newly developed local therapeutic modality which has been shown to be able to obtain complete response and cure in those early stage lung cancers with carcinoma in situ. The objective of this study is, first, to evaluate the activity and toxicity of PDT with Photofrin II in hilar type of early lung cancer, and second, to determine the complete response rate as primary end-point.

    2005-11-01

    Type I and Type II hair cells, and Type II hair cells located in different zones of the semicircular canal crista, express different patterns of voltage-dependent K channels, each one specifically shaping the hair cell receptor potential. We report here that, close to hatching, chicken embryo semicircular canal Type I and Type II hair cells express a similar voltage-dependent L-type calcium current (I(Ca)), whose main features are: activation above -60 mV, fast activation kinetics, and scarce inactivation. I(Ca) should be already active at rest in Zone 1 Type II hair cells, whose resting membrane potential was on average slightly less negative than -60 mV. Conversely, I(Ca) would not be active at rest in Type II hair cells from Zone 2 and 3, nor in Type I hair cells, since their resting membrane potential was significantly more negative than -60 mV. However, even small depolarising currents would activate I(Ca) steadily in Zone 2 and 3 Type II hair cells, but not in Type I hair cells because of the robust repolarising action of their specific array of K(+) currents. The implications of the present findings in the afferent discharge are discussed.

  11. Active locking and entanglement in type II optical parametric oscillators

    2018-02-01

    Type II optical parametric oscillators are amongst the highest-quality sources of quantum-correlated light. In particular, when pumped above threshold, such devices generate a pair of bright orthogonally-polarized beams with strong continuous-variable entanglement. However, these sources are of limited practical use, because the entangled beams emerge with different frequencies and a diffusing phase difference. It has been proven that the use of an internal wave-plate coupling the modes with orthogonal polarization is capable of locking the frequencies of the emerging beams to half the pump frequency, as well as reducing the phase-difference diffusion, at the expense of reducing the entanglement levels. In this work we characterize theoretically an alternative locking mechanism: the injection of a laser at half the pump frequency. Apart from being less invasive, this method should allow for an easier real-time experimental control. We show that such an injection is capable of generating the desired phase locking between the emerging beams, while still allowing for large levels of entanglement. Moreover, we find an additional region of the parameter space (at relatively large injections) where a mode with well defined polarization is in a highly amplitude-squeezed state.

    Diabetes Mellitus (DM) is considered to play a principle role in the etiopathogenesis of sexual dysfunction both in men and women. The aim of this study is to evaluate sexual function in Type II diabetic women. A total of 72 young diabetic women (mean age: 38.8 years) with no other systemic diseases and 60 age-matched healthy women were enrolled in our study. We sought from them a detailed medical and sexual history and used the Index of Female Sexual function (IFSF) questionnaire (Kaplan et al., 1999). The mean IFSF score of diabetic women was 29.3 +/- 6.4 and was 37.7 +/- 3.5 in normal cases (p diabetics and was observed in 77% of the women. Diminished clitoral sensation was observed in 62.5% of the women, 37.5% complained of vaginal dryness and 41.6% had vaginal discomfort. Orgasmic dysfunction was found in 49% of the women. The incidence of all these related symptoms were significantly higher when compared to controls. We concluded that significant percentage of diabetic women that we observed experience sexual dysfunction of varying degrees that diminishes their quality of life.

All the patients received multi-channel cochlear implantation through transmastoid facial recess approach. The postoperative outcomes of 12 cases were compared with 12 cases with no inner ear malformation as a control group. The electrodes were totally inserted into the cochlear successfully, there was no facial paralysis and cerebrospinal fluid leakage occurred after operation. The hearing threshold in this series were similar to that of the normal cochlear implantation. After more than half a year of speech rehabilitation, the abilities of speech discrimination and spoken language of all the patients were improved compared with that of preoperation. Multi-channel cochlear implantation could be performed in the cases with Waardenburg syndrome, preoperative hearing and images assessments should be done.

  14. Dentinogenesis imperfecta type II: approach for dental treatment

    Directory of Open Access Journals (Sweden)

    Raquel Mantuaneli Scarel-Caminaga

    Full Text Available INTRODUCTION: Dentinogenesis imperfecta (DI is a hereditary dentin development disorder that affects both primary and permanent dentitions. The DI characteristics are discolored and translucent teeth ranging from gray to brownish-blue or amber. The enamel may split readily from the dentin when subjected to occlusal stress. Radiographically there are evident of cervical constrictions, short root and pulp chambers, and the root canals are smaller than normal or completely obliterated. The dental treatment choice can be decided on a case-by case‑basis, considering the degree of dental tissue loss, and child age and cooperation. OBJECTIVE: The aim of this case report was to describe the early dental treatment performed in a child affected by DI type II. CASE REPORT: The treatment involved basic preventive procedures. Primary molars were worn to such an extent that the remained tooth structure was covered with composite resin to protect the exposed dentin. Resin-based sealant was applied in all first permanent molars. Posterior cross bite was treated with the expansion of the upper arch. CONCLUSION: The early treatment restored the patient´s vertical dimension resulting in acceptable esthetics and function for the permanent teeth to complete their eruption.

    In the lower solar atmosphere, the chromosphere is permeated by jets, in which plasma is propelled at speeds of 50-150 km/s into the Sun’s atmosphere or corona. Although these spicules may play a role in heating the million-degree corona and are associated with Alfvén waves that help drive the solar wind, their generation remains mysterious. We implemented in the radiative MHD Bifrost code the effects of partial ionization using the generalized Ohm’s law. This code also solves the full MHD equations with non-grey and non-LTE radiative transfer and thermal conduction along magnetic field lines. The ion-neutral collision frequency is computed using recent studies that improved the estimation of the cross sections under chromospheric conditions (Vranjes & Krstic 2013). Self-consistently driven jets (spicules type II) in magnetohydrodynamic simulations occur ubiquitously when magnetic tension is confined and transported upwards through interactions between ions and neutrals, and impulsively released to drive flows, heat plasma, generate Alfvén waves, and may play an important role in maintaining the substructure of loop fans. This mechanism explains how spicular plasma can be heated to millions of degrees and how Alfvén waves are generated in the chromosphere.

  16. Flux-line-cutting losses in type-II superconductors

    Energy dissipation associated with flux-line cutting (intersection and cross-joining of adjacent nonparallel vortices) is considered theoretically. The flux-line-cutting contribution to the dissipation per unit volume, arising from mutual annihilation of transverse magnetic flux, is identified as J/sub parallel/xE/sub parallel/, where J/sub parallel/ and E/sub parallel/ are the components of the current density and the electric field parallel to the magnetic induction. The dynamical behavior of the magnetic structure at the flux-line-cutting threshold is shown to be governed by a special critical-state model similar to that proposed by previous authors. The resulting flux-line-cutting critical-state model, characterized in planar geometry by a parallel critical current density J/sub c/parallel or a critical angle gradient k/sub c/, is used to calculate predicted hysteretic ac flux-line-cutting losses in type-II superconductors in which the flux pinning is weak. The relation of the theory to previous experiments is discussed

    Background Cerebral vasculopathy in sickle cell anemia (SCA) begins in childhood and features intracranial arterial stenosis with high risk of ischemic stroke. Stroke risk can be reduced by transcranial doppler (TCD) screening and chronic transfusion therapy; however, this approach is impractical in many developing countries. Accumulating evidence supports the use of hydroxyurea for the prevention and treatment of cerebrovascular disease in children with SCA. Recently we reported that hydroxy...

  18. Redesigning the type II' β-turn in green fluorescent protein to type I': implications for folding kinetics and stability.

    Both Type I' and Type II' β-turns have the same sense of the β-turn twist that is compatible with the β-sheet twist. They occur predominantly in two residue β-hairpins, but the occurrence of Type I' β-turns is two times higher than Type II' β-turns. This suggests that Type I' β-turns may be more stable than Type II' β-turns, and Type I' β-turn sequence and structure can be more favorable for protein folding than Type II' β-turns. Here, we redesigned the native Type II' β-turn in GFP to Type I' β-turn, and investigated its effect on protein folding and stability. The Type I' β-turns were designed based on the statistical analysis of residues in natural Type I' β-turns. The substitution of the native "GD" sequence of i+1 and i+2 residues with Type I' preferred "(N/D)G" sequence motif increased the folding rate by 50% and slightly improved the thermodynamic stability. Despite the enhancement of in vitro refolding kinetics and stability of the redesigned mutants, they showed poor soluble expression level compared to wild type. To overcome this problem, i and i + 3 residues of the designed Type I' β-turn were further engineered. The mutation of Thr to Lys at i + 3 could restore the in vivo soluble expression of the Type I' mutant. This study indicates that Type II' β-turns in natural β-hairpins can be further optimized by converting the sequence to Type I'. © 2014 Wiley Periodicals, Inc.

    Alveolar type II cells have multiple functions, including surfactant production and fluid clearance, which are critical for lung function. Differentiation of type II cells occurs in cultured fetal lung epithelial cells treated with dexamethasone plus cAMP and isobutylmethylxanthine (DCI) and involves increased expression of 388 genes. In this study, type II cells of human adult lung were isolated at ∼95% purity, and gene expression was determined (Affymetrix) before and after culturing 5 days...

  1. Resveratrol: A novel type of topoisomerase II inhibitor.

    2017-12-22

    Resveratrol, a polyphenol found in various plant sources, has gained attention as a possible agent responsible for the purported health benefits of certain foods, such as red wine. Despite annual multi-million dollar market sales as a nutriceutical, there is little consensus about the physiological roles of resveratrol. One suggested molecular target of resveratrol is eukaryotic topoisomerase II (topo II), an enzyme essential for chromosome segregation and DNA supercoiling homeostasis. Interestingly, resveratrol is chemically similar to ICRF-187, a clinically approved chemotherapeutic that stabilizes an ATP-dependent dimerization interface in topo II to block enzyme activity. Based on this similarity, we hypothesized that resveratrol may antagonize topo II by a similar mechanism. Using a variety of biochemical assays, we find that resveratrol indeed acts through the ICRF-187 binding locus, but that it inhibits topo II by preventing ATPase domain dimerization rather than stabilizing it. This work presents the first comprehensive analysis of the biochemical effects of both ICRF-187 and resveratrol on the human isoforms of topo II, and reveals a new mode for the allosteric regulation of topo II through modulation of ATPase status. Natural polyphenols related to resveratrol that have been shown to impact topo II function may operate in a similar manner. © 2017 by The American Society for Biochemistry and Molecular Biology, Inc.

    Congenital dyserythropoietic anemias (CDAs) are rare hereditary disorders characterized by ineffective erythropoiesis and by distinct morphological abnormalities of erythroblasts in the bone marrow. Characteristic morphological aberrations were the cornerstone of diagnosis, but following the identification of several causative genes, the molecular approach could represent a rapid tool for the identification of these conditions. This review presents advances in diagnosis and classification of CDAs. The classification of CDAs has long been based on morphological features. Now, the discovery of some of the responsible genes allows reconsideration of part of the classification. The first CDA partly accounted for genetically has been CDA 1, through the discovery in 2002 of the gene responsible, CDAN1, encoding codanin-1. Recently, the dramatic identification of the genes responsible for CDA II, SEC23B, and for a hitherto unnamed CDA, KLF1, took place. SEC23B encodes SEC23B which is a component of the coated vesicles transiting from the endoplasmic reticulum to the cis compartment of the Golgi apparatus. A unique mutation in KLF1, which encodes the erythroid transcription factor KLF1, causes major ultrastructural abnormalities, the persistence of embryonic and fetal hemoglobins, and the absence of some red cell membrane proteins. Studies of genotype-phenotype relationship, as has already been done for CDA II, will allow a more accurate prognosis. Identification of the responsible genes has opened new vistas for research on CDAs.

    Rationale: Cross-sectional association has been reported between sleep-disordered breathing (SDB) and insulin resistance, but no prospective studies have been performed to determine whether SDB is causal in the development of diabetes. Objectives: The purpose of our study was to investigate the prevalence and incidence of type II diabetes in subjects with SDB and whether an independent relationship exists between them. Methods: A cross-sectional and longitudinal analysis was performed in 1,387 participants of the Wisconsin Sleep Cohort. Full polysomnography was used to characterize SDB. Diabetes was defined in two ways: (1) physician-diagnosis alone or (2) for those with glucose measurements, either fasting glucose ⩾ 126 mg/dl or physician diagnosis. Measurements and Main Results: There was a greater prevalence of diabetes in subjects with increasing levels of SDB. A total of 14.7% of subjects with an apnea–hypopnea index (AHI) of 15 or more had a diagnosis of diabetes compared with 2.8% of subjects with an AHI of less than 5. The odds ratio for having a physician diagnoses of diabetes mellitus with an AHI of 15 or greater versus an AHI of less than 5 was 2.30 (95% confidence interval, 1.28–4.11; p = 0.005) after adjustment for age, sex, and body habitus. The odds ratio for developing diabetes mellitus within 4 yr with an AHI of 15 or more compared with an AHI of less than 5 was 1.62 (95% confidence interval, 0.67–3.65; p = 0.24) when adjusting for age, sex, and body habitus. Conclusions: Diabetes is more prevalent in SDB and this relationship is independent of other risk factors. However, it is not clear that SDB is causal in the development of diabetes. PMID:16192452

    This randomized, double-blind, placebo-controlled study was conducted to investigate the efficacy, safety and tolerability of policosanol, a cholesterol-lowering drug purified from sugar-cane wax, in postmenopausal women with type II hypercholesterolemia. A total of 244 women who had experienced the menopause and showed elevated serum total cholesterol and low-density lipoprotein cholesterol (LDL-C) levels despite 6 weeks on a standard lipid-lowering diet were randomized to receive placebo or policosanol 5 mg/day for 12 weeks, after which the dose was doubled to 10 mg/day for the next 12 weeks. Policosanol (5 and 10 mg/day) significantly lowered LDL-C levels (17.7% and 25.2%, respectively) and total cholesterol (12.6% and 16.7%, respectively), as well as the ratios of LDL-C to high-density lipoprotein cholesterol (HDL-C) (17.0% and 29.3%, respectively) and total cholesterol to HDL-C (16.7% and 27.2%, respectively), compared to the baseline and placebo; at the same time, policosanol significantly raised HDL-C levels by 16.5% and 29.3%, respectively. The drug was safe and well tolerated. No drug-related adverse events were observed, and even the extent of adverse events was less in the policosanol group than in the placebo group. Four serious adverse events occurred in the placebo group (one myocardial infarction, two cases of hypertensive status and one surgical intervention) compared to none in the policosanol group. In conclusion, policosanol is effective, safe and well tolerated in hypercholesterolemic postmenopausal women.

    Type II hyperprolinemia is an autosomal recessive disorder caused by a deficiency in {Delta}{sup 1}-pyrroline-5-carboxylate dehydrogenase (P5CDH; also known as ALDH4A1), the aldehyde dehydrogenase that catalyzes the oxidation of glutamate semialdehyde to glutamate. Here, we report the first structure of human P5CDH (HsP5CDH) and investigate the impact of the hyperprolinemia-associated mutation of Ser352 to Leu on the structure and catalytic properties of the enzyme. The 2. 5-{angstrom}-resolution crystal structure of HsP5CDH was determined using experimental phasing. Structures of the mutant enzymes S352A (2.4 {angstrom}) and S352L (2.85 {angstrom}) were determined to elucidate the structural consequences of altering Ser352. Structures of the 93% identical mouse P5CDH complexed with sulfate ion (1.3 {angstrom} resolution), glutamate (1.5 {angstrom}), and NAD{sup +} (1.5 {angstrom}) were determined to obtain high-resolution views of the active site. Together, the structures show that Ser352 occupies a hydrophilic pocket and is connected via water-mediated hydrogen bonds to catalytic Cys348. Mutation of Ser352 to Leu is shown to abolish catalytic activity and eliminate NAD{sup +} binding. Analysis of the S352A mutant shows that these functional defects are caused by the introduction of the nonpolar Leu352 side chain rather than the removal of the Ser352 hydroxyl. The S352L structure shows that the mutation induces a dramatic 8-{angstrom} rearrangement of the catalytic loop. Because of this conformational change, Ser349 is not positioned to interact with the aldehyde substrate, conserved Glu447 is no longer poised to bind NAD{sup +}, and Cys348 faces the wrong direction for nucleophilic attack. These structural alterations render the enzyme inactive.

  6. Behavioral effects of type II pyrethroid cyhalothrin in rats

    Synthetic pyrethroids such as cyhalothrin are extensively used in agriculture for the control of a broad range of ectoparasites in farm animals. It has been suggested that type II pyrethroids might induce anxiogenic-like effects in laboratory animals. The present study was undertaken to investigate a possible anxiogenic-like outcome of cyhalothrin in rats. Adult male rats were orally dosed for 7 days with 1.0, 3.0, or 7.0 mg/kg/day of cyhalothrin, present in a commercial formulation (Grenade Coopers do Brazil S.A.). The neurobehavioral changes induced by cyhalothrin as well as those produced on corticosterone serum levels were measured 24 h after the last treatment. Picrotoxin (1.0 mg/kg) was also acutely used as a positive control for anxiety. Results showed that cyhalothrin: (1) induced some signs and symptoms of intoxication that included salivation, tremors, and liquid feces; (2) reduced total locomotor activity in the open-field; (3) reduced the percentage of time spent in open-field central zones; (4) increased immobility time in the open-field; (5) reduced the percentage of time spent in plus-maze open arms exploration; (6) reduced the time spent in social interactions, and (7) increased the levels of serum corticosterone. The behavioral changes reported for cyhalothrin (3.0 mg/kg/day) were similar of those induced by picrotoxin. The no effect level dose obtained for cyhalothrin in this study was 1.0 mg/kg/day. These results provide experimental evidence that cyhalothrin induces anxiety-like symptoms, with this effect being dose-related. Thus, anxiety must be included among the several signs and symptoms of pesticide intoxication

    Diabetes Mellitus Type II (T2DM) is a major and growing medical, social and economic burden in the East-Asian country of Cambodia. However, no economic modelling has been done to predict the number of cases and the budget impact. This paper forecasts the epidemiological and economic consequences of T2DM in Cambodia. The Ministry of Health and related donor agencies are supported to select the most cost-effective interventions against the disease. At the same time this paper demonstrates the relevance and potential of health economic modelling for least developed countries. We developed a Markov-Model for the specific situation of Cambodia. Data was taken from the scientific literature, grey literature in Cambodia and key-informant interviews. The number of people living with T2DM is steadily increasing from 145,000 in the year 2008 to 264,000 in the year 2028 (+82 %). In the year 2008 the diagnosed T2DM patients would incur costs of some 2 million US$ to cover all of diabetes treatment. 57 % of this amount would have to be spent for OAD-therapy, the rest for insulin therapy. In the year 2028 this amount will have grown to some 4 million US$. If all patients (incl. non-diagnosed) had to be paid-for the respective figure would be 5.5 million and 11 million US$. Screening for T2DM is only cost-effective if the sensitivity of the test is high while the unit price is low. The results of this simulation call for targeting the high-risk groups. However, an increased availability of Oral Anti-Diabetic and Insulin Therapy is highly cost-effective. Type 2 Diabetes Mellitus is a major public health challenge in Cambodia. The simulations clearly indicate that prevention and treatment of this disease is highly cost-effective. However, not everything that is cost-effective might be affordable in Cambodia. This country will require external support to ease the growing burden of T2DM.

    Coffee and other sources of methylxanthines and risk of Type I vs Type II endometrial cancer (EC) have not been evaluated previously. Prospective cohort of 23,356 postmenopausal women with 471 Type I and 71 Type II EC cases. Type I EC was statistically significantly associated with caffeinated (relative risk (RR)=0.65 for 4+ cups per day vs ≤1 cup per month: 95% confidence interval (CI): 0.47-0.89) but not decaffeinated (RR=0.76; 95% CI: 0.50-1.15) coffee intake; there were no associations with tea, cola or chocolate, or for Type II EC. The inverse association with caffeinated coffee intake was specific to women with a body mass index 30+ kg m(-2) (RR=0.56; 95% CI: 0.36-0.89). Coffee may protect against Type I EC in obese postmenopausal women.

    Anemia seems to have a clear relationship with cerebrovascular events (CVEs), as there is a direct connection between central nervous system, blood supply, and tissue oxygen delivery. Anemia is considered a hyperkinetic state which disturbs endothelial adhesion molecule genes that may lead to thrombus formation. Furthermore, blood flow augmentation and turbulence may result in the migration of this thrombus, thus producing artery-to-artery embolism. It is for this reason that anemia is characterized as "the fifth cardiovascular risk factor." Anemia is consistently present in patients with acute stroke, ranging from 15% to 29%, while the mortality rate was significantly higher in patients suffering from anemia at the time of admission. Different types of anemia (sickle cell disease, beta thalassemia, iron deficiency anemia [IDA]) have been associated with increased cardiovascular and CVE risk. The relation between hemoglobin level and stroke would require further investigation. Unfortunately, treatment of anemia in cardiovascular and cerebrovascular disease still lacks clear targets and specific therapy has not developed. However, packed red blood cell transfusion is generally reserved for therapy in patients with CVEs. What is more, treatment of IDA prevents thrombosis and the occurrence of stroke; although iron levels should be checked, chronic administration favors thrombosis. Regarding erythropoietin (EPO), as there is lack of studies in anemic stroke patients, it would be desirable to utilize both neuroprotective and hematopoietic properties of EPO in anemic stroke patients. This review aims to clarify the poorly investigated and defined issues concerning the relation of anemia and CVEs. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Red blood cell (RBC) destruction can be secondary to intrinsic disorders of the RBC or to extrinsic causes. In the congenital hemolytic anemias, intrinsic RBC enzyme, RBC membrane, and hemoglobin disorders result in hemolysis. The typical clinical presentation is a patient with pallor, anemia, jaundice, and often splenomegaly. The laboratory features include anemia, hyperbilirubinemia, and reticulocytosis. For some congenital hemolytic anemias, splenectomy is curative. However, in other diseases, avoidance of drugs and toxins is the best therapy. Supportive care with transfusions are also mainstays of therapy. Chronic hemolysis often results in the formation of gallstones, and cholecystectomy is often indicated. Copyright © 2016 Elsevier Inc.

    The effects of low-dose rate gamma-irradiation were investigated in two mouse strains - C57BL/KsJ-db/db (db mouse) and AKITA (AKITA mouse)-for type II diabetes mellitus. Both strains develop the developed type II diabetes by about 8 weeks of age due to dysfunction of the insulin/insulin receptor. The db Mouse' shows obese and exhibits hyperinsulinism, and the onset of Type II diabetes like resembles that for Westerners. On the other hand, the AKITA mouse has exhibits disordered insulin secretion, and the diabetes such as resembles that of Asians. Ten-week old female mice, in groups of 8 or 12, were irradiated at 0.65 mGy/hr in the low-dose rate irradiation facility in the Low Dose Radiation Research Center. The level of urine glucose was measured with test slips. The urine glucose levels of all of the mice were highly elevated the beginning of the irradiation. In the irradiated group of db mice, three mice showed decrease in glucose level compare to the level of non-irradiated diabetes mice after 35, 52 or 80 weeks of irradiation. All had maintained a normal level thereafter. No such improvement in diabetes was ever observed in the 12 mice of in the non-irradiated control group. The AKITA mice, however, did not decrease the glucose level regardless of the irradiation. Both the db mice and AKITA mice had their lives prolonged their life by the irradiation. The survival rate of db mice at the age of 90 weeks was 75% in the irradiated group, but 50% in the non-irradiated group. The average life span was 104 weeks in the irradiated group and 87 weeks in the control group. Furthermore, a marked difference was furthermore observed in the appearance of the coat hair, skin, and tail; appearances were well preserved in the irradiated group. The average life span in the irradiated AKITA mice was also longer than that for the non-irradiated mice, 51 weeks and 41 weeks in the irradiated and non-irradiated group respectively. These results suggest that the low-dose irradiation

    To analyze the correlation between dysplastic lineage and type of cytopenia in myelodysplastic syndromes. We analyzed the correlation between dysplasia and cell count using the data set of our previous morphologic study. There were no correlations between dysgranulopoiesis of 10% or more and absolute neutrophil count (ANC). Similarly, hyposegmented mature neutrophils (Pelger) of 10% or more were not related to ANC. Interestingly, the platelet count of patients with dysmegakaryopoiesis (dys Mgk) was higher than that of patients without dys Mgk (dys Mgk ≥10% vs <10%, P = .08; dys Mgk ≥40% vs <40%, P = .02; micromegakaryocytes ≥10% vs <10%, P = .004). Since low cell counts did not correlate with the presence of dysplastic features, we suggest that dysplastic features do not directly relate to apoptosis.

  19. Rules for distinguishing toxicants that cause type I and type II narcosis syndromes.

    Science.gov (United States)

    Veith, G D; Broderius, S J

    1990-01-01

    Narcosis is a nonspecific reversible state of arrested activity of protoplasmic structures caused by a wide variety of organic chemicals. The vast majority of industrial organic chemicals can be characterized by a baseline structure-toxicity relationship as developed for diverse aquatic organisms, using only the n-octanol/water partition coefficient as a descriptor. There are, however, many apparent narcotic chemicals that are more toxic than baseline narcosis predicts. Some of these chemicals have been distinguished as polar narcotics. Joint toxic theory and isobole diagrams were used to show that chemicals strictly additive with phenol were generally more toxic than predicted by narcosis I models and characterized by a different mode of action called narcosis II syndrome. This type of toxicity is exemplified by certain amides, amines, phenols, and nitrogen heterocycles. Evidence is provided that suggests that narcosis II syndrome may result from the presence of a strong hydrogen bonding group on the molecule, and narcosis I syndrome results from hydrophobic bonding of the chemical to enzymes and/or membranes. This shift in toxic action is apparently indistinguishable for narcotic chemicals with log P greater than about 2.7. General rules for selecting the appropriate models are proposed. PMID:2269227

    Restoration of the alveolar epithelium after injury is thought to be dependent on the proliferation of alveolar type II cells. To understand the factors that may be involved in promoting type II cell proliferation in vivo, we determined the effect of potential mitogens and culture substrata on DNA synthesis in rat alveolar type II cells in primary culture. Type II cells cultured in basal medium containing 10% fetal bovine serum (FBS) exhibited essentially no DNA synthesis. Factors that stimulated 3 H-thymidine incorporation included cholera toxin, epidermal growth factor, and rat serum. The greatest degree of stimulation was achieved by plating type II cells on an extracellular matrix prepared from bovine corneal endothelial cells and then by culturing the pneumocytes in medium containing rat serum, cholera toxin, insulin, and epidermal growth factor. Under conditions of stimulation of 3 H-thymidine incorporation there was an increased DNA content per culture dish but no increase in cell number. The ability of various culture conditions to promote DNA synthesis in type II cells was verified by autoradiography. Type II cells were identified by the presence of cytoplasmic inclusions, which were visualized by tannic acid staining before autoradiography. These results demonstrate the importance of soluble factors and culture substratum in stimulating DNA synthesis in rat alveolar type II cells in primary culture

    A cultured cell line that maintained expression of pulmonary type II cell markers of differentiation would be advantageous to generate a large number of homogenous cells in which to study the biochemical functions of type II cells. Type II epithelial cells are the source of pulmonary surfactant and a cell of origin for pulmonary adenomas. Last year our laboratory reported the induction of expression of two phenotypic markers of pulmonary type II cells (alkaline phosphatase activity and surfactant lipid synthesis) in cultured fetal rat lung epithelial (FRLE) cells, a spontaneously immortalized cell line of fetal rat lung type II cell origin. Subsequently, the induction of the ability to synthesize surfactant lipid became difficult to repeat. We hypothesized that the cell line was heterogenuous and some cells were more like type II cells than others. The purpose of this study was to test this hypothesis and to obtain a cultured cell line with type II cell phenotypic markers by cloning several FRLE cells and characterizing them for phenotypic markers of type II cells (alkaline phosphatase activity and presence of surfactant lipids). Thirty cloned cell lines were analyzed for induced alkaline phosphatase activity (on x-axis) and for percent of phospholipids that were disaturated (i.e., surfactant).

  5. Role of Complement in Autoimmune Hemolytic Anemia

    2015-01-01

    Summary The classification of autoimmune hemolytic anemias and the complement system are reviewed. In autoimmune hemolytic anemia of the warm antibody type, complement-mediated cell lysis is clinically relevant in a proportion of the patients but is hardly essential for hemolysis in most patients. Cold antibody-mediated autoimmune hemolytic anemias (primary cold agglutinin disease, secondary cold agglutinin syndrome and paroxysmal cold hemoglobinuria) are entirely complement-mediated disorders. In cold agglutinin disease, efficient therapies have been developed in order to target the pathogenic B-cell clone, but complement modulation remains promising in some clinical situations. No established therapy exists for secondary cold agglutinin syndrome and paroxysmal cold hemoglobinuria, and the possibility of therapeutic complement inhibition is interesting. Currently, complement modulation is not clinically documented in any autoimmune hemolytic anemia. The most relevant candidate drugs and possible target levels of action are discussed. PMID:26696798

  8. Oxidative Metabolites of Curcumin Poison Human Type II Topoisomerases†

    The polyphenol curcumin is the principal flavor and color component of the spice turmeric. Beyond its culinary uses, curcumin is believed to positively impact human health and displays antioxidant, anti-inflammatory, antibacterial, and chemopreventive properties. It also is in clinical trials as an anticancer agent. In aqueous solution at physiological pH, curcumin undergoes spontaneous autoxidation that is enhanced by oxidizing agents. The reaction proceeds through a series of quinone methide and other reactive intermediates to form a final dioxygenated bicyclopentadione product. Several naturally occurring polyphenols that can form quinones have been shown to act as topoisomerase II poisons (i.e., increase levels of topoisomerase II-mediated DNA cleavage). Because several of these compounds have chemopreventive properties, we determined the effects of curcumin, its oxidative metabolites, and structurally related degradation products (vanillin, ferulic acid, and feruloylmethane), on the DNA cleavage activities of human topoisomerase IIα and IIβ. Intermediates in the curcumin oxidation pathway increased DNA scission mediated by both enzymes ~4-5–fold. In contrast, curcumin and the bicyclopentadione, as well as vanillin, ferulic acid, and feruloylmethane, had no effect on DNA cleavage. As found for other quinone-based compounds, curcumin oxidation intermediates acted as redox-dependent (as opposed to interfacial) topoisomerase II poisons. Finally, under conditions that promote oxidation, the dietary spice turmeric enhanced topoisomerase II-mediated DNA cleavage. Thus, even within the more complex spice formulation, oxidized curcumin intermediates appear to function as topoisomerase II poisons. PMID:23253398

  11. Flux tubes and the type-I/type-II transition in a superconductor coupled to a superfluid

    Alford, Mark G.; Good, Gerald

    2008-01-01

    We analyze magnetic-flux tubes at zero temperature in a superconductor that is coupled to a superfluid via both density and gradient ('entrainment') interactions. The example we have in mind is high-density nuclear matter, which is a proton superconductor and a neutron superfluid, but our treatment is general and simple, modeling the interactions as a Ginzburg-Landau effective theory with four-fermion couplings, including only s-wave pairing. We numerically solve the field equations for flux tubes with an arbitrary number of flux quanta and compare their energies. This allows us to map the type-I/type-II transition in the superconductor, which occurs at the conventional κ≡λ/ξ=1/√(2) if the condensates are uncoupled. We find that a density coupling between the condensates raises the critical κ and, for a sufficiently high neutron density, resolves the type-I/type-II transition line into an infinite number of bands corresponding to 'type-II(n)' phases, in which n, the number of quanta in the favored flux tube, steps from 1 to infinity. For lower neutron density, the coupling creates spinodal regions around the type-I/type-II boundary, in which metastable flux configurations are possible. We find that a gradient coupling between the condensates lowers the critical κ and creates spinodal regions. These exotic phenomena may not occur in nuclear matter, which is thought to be deep in the type-II region but might be observed in condensed-matter systems

  10. Hematologic Disorders: Anemia.

    Science.gov (United States)

    2015-06-01

    Anemia occurs in up to 25% of the US population. Normal hemoglobin levels vary by race, sex, and age. Classification of anemia by mean corpuscular volume guides the differential diagnosis and evaluation. Iron studies, reticulocyte count, the red blood cell distribution width index, and blood test results are used to make the diagnosis. Iron deficiency anemia is the most common microcytic anemia and is managed with iron therapy. Parenteral iron is available when the oral route cannot be used. Patients who do not benefit from therapy should be evaluated for adherence, malabsorption, occult bleeding, systemic disease, or less common inherited disorders. A source of gastrointestinal bleeding is found in 60% to 70% of patients with iron deficiency anemia who are referred for endoscopy. Normocytic anemia has a broad differential, including nutritional deficiencies, blood loss, renal disease, malignancy (solid tumors or hematologic cancer), rheumatologic disorders, endocrine disorders, and other systemic diseases. Macrocytic anemias are seen with vitamin B12 and folate deficiency, alcohol use, thyroid disease, hydroxyurea, antiretroviral drugs, myelodysplastic syndromes, and myeloma. Oral vitamin B12 is underused, and can be as effective as intramuscular vitamin B12 in managing anemia due to vitamin B12 deficiency.

  13. Anemia in the elderly: a consequence of aging?

    Science.gov (United States)

    Halawi, Racha; Moukhadder, Hassan; Taher, Ali

    2017-04-01

    Anemia in the elderly is a common finding that is associated with a poorer quality of life, worse outcomes, and increased mortality. While this entity is frequently overlooked, there is often an underlying cause that is correctable. Areas covered: In this review, we shed light on the prevalence of anemia in the elderly population, review the most common causes, particularly iron deficiency anemia and anemia of chronic disease, and describe the available treatment modalities. When a clear etiology for the anemia is ruled-out, the term unexplained anemia may be utilized; while still an under-explored field, one of the underlying pathophysiological mechanisms appears to be associated with an age-related inflammatory process. Expert commentary: Treating anemia secondary to nutritional deficiencies can be straightforward, but the management of the other types of anemia is not always the case. Treating anemia of chronic disease and anemia of chronic kidney disease may be limited by elevated levels of hepcidin and new promising treatments are still in pre-clinical and clinical trial phases. Caution should be employed when using erythropoiesis stimulating agents due to safety concerns, and when prescribing blood transfusion therapy, both of which lack the specific guidelines for use in the elderly.

  14. Expression Profiles of Cellular Retinol-binding Protein, Type II (CRBP II in Erlang Mountainous Chickens

    Directory of Open Access Journals (Sweden)

    H. D. Yin

    2014-03-01

    Full Text Available Cellular retinol-binding protein II (CRBP II belongs to the family of cellular retinol-binding proteins and plays a major role in absorption, transport, and metabolism of vitamin A. In addition, because vitamin A is correlated with reproductive performance, we measured CRBP II mRNA abundance in erlang mountainous chickens by real-time PCR using the relative quantification method. The expression of CRBP II showed a tissue-specific pattern and egg production rate-dependent changes. The expression was very high (p<0.05 in jejunum and liver, intermediate in kidney, ovary, and oviduct, and lowest (p<0.05 in heart, hypothalamus, and pituitary. In the hypothalamus, oviduct, ovary, and pituitary, CRBP II mRNA abundance were correlated to egg production rate, which increased from 12 wk to 32 wk, peaked at 32 wk relative to the other time points, and then decreased from 32 wk to 45 wk. In contrast, the expression of CRBP II mRNA in heart, jejunum, kidney, and liver was not different at any of the ages evaluated in this study. These data may help to understand the genetic basis of vitamin A metabolism, and suggest that CRBP II may be a candidate gene to affect egg production traits in chickens.

    The erythrocyte lifespan in haemolytic anemia is shortened while erythropoesis is increased. Important labaratory findings are increased reticulocytes, LDH, indirect bilirubin and a decreased haptoglobin level. The most important diagnostic tool for further work up of hemolytic anemia is the direct antiglobulin test (DAT, Coombs test) to differentiate autoimmune hemolytic anemia (AIHA) from other causes. Another important group are fragmentation syndroms (hemolytic uremic syndrome and thrombotic thrombocytopenic purpura). In these forms of haemolytic anemia fragmented red blood cells can be found in the blood smear together with thrombocytopenia. A severe problem in paroxysmal nocturnal hematuria is the incidence of thrombosis. The following review describes the most important forms of hemolytic anemia in the adult and the diagnostic and therapeutic strategies. © Georg Thieme Verlag KG Stuttgart · New York.

  18. Interplay of type I and type II seesaw contributions to neutrino mass

    International Nuclear Information System (INIS)

    Akhmedov, Evgeny Kh.; Frigerio, Michele

    2007-01-01

    Type I and type II seesaw contributions to the mass matrix of light neutrinos are inherently related if left-right symmetry is realized at high energy scales. We investigate implications of such a relation for the interpretation of neutrino data. We proved recently that the left-right symmetric seesaw equation has eight solutions, related by a duality property, for the mass matrix of right-handed neutrinos M R . In this paper the eight allowed structures of M R are reconstructed analytically and analyzed numerically in a bottom-up approach. We study the dependence of right-handed neutrino masses on the mass spectrum of light neutrinos, mixing angle θ 13 , leptonic CP violation, scale of left-right symmetry breaking and on the hierarchy in neutrino Yukawa couplings. The structure of the seesaw formula in several specific SO(10) models is explored in the light of the duality. The outcome of leptogenesis may depend crucially on the choice among the allowed structures of M R and on the level crossing between right-handed neutrino masses

  19. Type II NKT cells: a distinct CD1d-restricted immune regulatory NKT cell subset.

    Science.gov (United States)

    Dasgupta, Suryasarathi; Kumar, Vipin

    2016-08-01

    Type II natural killer T cells (NKT) are a subset of the innate-like CD1d-restricted lymphocytes that are reactive to lipid antigens. Unlike the type I NKT cells, which express a semi-invariant TCR, type II NKT cells express a broader TCR repertoire. Additionally, other features, such as their predominance over type I cells in humans versus mice, the nature of their ligands, CD1d/lipid/TCR binding, and modulation of immune responses, distinguish type II NKT cells from type I NKT cells. Interestingly, it is the self-lipid-reactivity of type II NKT cells that has helped define their physiological role in health and in disease. The discovery of sulfatide as one of the major antigens for CD1d-restricted type II NKT cells in mice has been instrumental in the characterization of these cells, including the TCR repertoire, the crystal structure of the CD1d/lipid/TCR complex, and their function. Subsequently, several other glycolipids and phospholipids from both endogenous and microbial sources have been shown to activate type II NKT cells. The activation of a specific subset of type II NKT cells following administration with sulfatide or lysophosphatidylcholine (LPC) leads to engagement of a dominant immunoregulatory pathway associated with the inactivation of type I NKT cells, conventional dendritic cells, and inhibition of the proinflammatory Th1/Th17 cells. Thus, type II NKT cells have been shown to be immunosuppressive in autoimmune diseases, inflammatory liver diseases, and in cancer. Knowing their relatively higher prevalence in human than type I NKT cells, understanding their biology is imperative for health and disease.

    Naive CD4+ T cells differentiate into T helper cells (Th1 and Th2) that play an essential role in the cardiovascular diseases. However, the molecular mechanism by which angiotensin II (Ang II) promotes Th1 differentiation remains unclear. The aim of this study was to determine whether the Ang II-induced Th1 differentiation regulated by ubiquitin-proteasome system (UPS). Jurkat cells were treated with Ang II (100 nM) in the presence or absence of different inhibitors. The gene mRNA levels were detected by real-time quantitative PCR analysis. The protein levels were measured by ELISA assay or Western blot analysis, respectively. Ang II treatment significantly induced a shift from Th0 to Th1 cell differentiation, which was markedly blocked by angiotensin II type 1 receptor (AT1R) inhibitor Losartan (LST). Moreover, Ang II significantly increased the activities and the expression of proteasome catalytic subunits (β1, β1i, β2i and β5i) in a dose- and time-dependent manner. However, Ang II-induced proteasome activities were remarkably abrogated by LST and PKA inhibitor H-89. Mechanistically, Ang II-induced Th1 differentiation was at least in part through proteasome-mediated degradation of IκBα and MKP-1 and activation of STAT1 and NF-κB. This study for the first time demonstrates that Ang II activates AT1R-PKA-proteasome pathway, which promotes degradation of IκBα and MKP-1 and activation of STAT1 and NF-κB thereby leading to Th1 differentiation. Thus, inhibition of proteasome activation might be a potential therapeutic target for Th1-mediated diseases. © 2018 The Author(s). Published by S. Karger AG, Basel.

    Characterize anemia in children aged between 12 and 59 months from urban areas in the provinces of Coronel Portillo and Huancavelica in Peru. Cross-sectional study carried out in two stages: a) population-based study to identify children with anemia using multistage probability sampling, and b) characterization of the serum levels of ferritin, vitamin B12, intraerythrocytic folic acid and presence of parasitosis in children with anemia. For the statistical analysis, expansion factors calculated from the sampling plan were applied. The prevalence of anemia was 55.9% in Huancavelica and 36.2% in Coronel Portillo. In Huancavelica, the coexistence of anemia with iron deficiency was 22.8% and anemia with vitamin B12 deficiency was 11%. In Coronel Portillo, the coexistence of anemia with iron deficiency and vitamin B12 deficiency was 15.2% and 29.7%, respectively. The most common types of anemia in Huancavelica were anemia with concurrent parasitosis (50.9%), iron deficiency anemia and parasitosis (12.3%), and iron deficiency alone (6.4%). In Coronel Portillo, it was anemia and parasitosis (54.4%), vitamin B12 deficiency and parasitosis (18.4%), and iron deficiency anemia and parasitosis (6.3%). The prevalence of anemia is higher than the national average, with anemia concurrent with parasitosis and anemia concurrent with two or more causes as the most common type. Consideration should be given to different causes other than iron deficiency in the programs of anemia contol for Peruvian children.

    Purpose: To investigate the pattern of brain volume changes of the brain in patients with type II diabetes mellitus using voxel-based morphometry. Material and methods: Institutional ethics approval and informed consent were obtained. VBM based on the high resolution three-dimensional T1-weighted fast spoiled gradient recalled echo MRI images was obtained from 16 type II diabetes patients (mean age 61.2 years) and 16 normal controls (mean age 59.6 years). All images were spatially preprocessed using Diffeomorphic Anatomical Registration using Exponentiated Lie algebra (DARTEL) algorithm, and the DARTEL templates were made from 100 normal subjects. Statistical parametric mapping was generated using analysis of covariance (ANCOVA). Results: An atrophy pattern of gray matter was seen in type II diabetes patients compared with controls that involved the right superior, middle, and inferior temporal gyri, right precentral gyrus, and left rolandic operculum region. The loss of white matter volume in type II diabetes mellitus was observed in right temporal lobe and left inferior frontal triangle region. ROI analysis revealed that the gray and white matter volume of right temporal lobe were significant lower in type II diabetes mellitus than that in controls (P < 0.05). Conclusion: This work demonstrated that type II diabetes mellitus patients mainly exhibited gray and white matter atrophy in right temporal lobe, and this finding supported that type II diabetes mellitus could lead to subtle diabetic brain structural changes in patients without dementia or macrovascular complications.

    AIM: To evaluate cladribine [2-chlorodeoxyadenosine (2-CdA)] therapy in refractory celiac disease (RCD) II. METHODS: An open-label cohort-study of RCD II patients treated with 2-CdA was performed between 2000 and 2010. Survival rate, enteropathy associated T-cell lymphoma (EATL) occurrence, clinical course, and histological and immunological response rates were evaluated. RESULTS: Overall, 32 patients were included with a median follow-up of 31 mo. Eighteen patients responded well to 2-CdA. Patients responsive to 2-CdA had a statistically significant increased survival compared to those who were unresponsive. The overall 3- and 5-year survival was 83% in the responder and 63% and 22% in the non-responder group, respectively. The overall 2-year clinical, histological and immunological response rates were 81%, 47% and 41%, respectively. Progression into EATL was reported in 16%, all of these patients died. CONCLUSION: Treatment of RCD II with 2-CdA holds promise, showing excellent clinical and histological response rates, and probably less frequent transition into EATL. PMID:21274381

    Proliferation of alveolar type II cells after lung injury is important for the restoration of the alveolar epithelium. Bronchoalveolar lavage fluid (BALF) may represent an important source of growth factors for alveolar type II cells. To test this possibility, BALF fluid was collected from normal rats, concentrated 10-fold by Amicon filtration, and tested for its ability to stimulate DNA synthesis in rat alveolar type II cells in primary culture. BALF induced a dose-dependent increase in type II cell DNA synthesis resulting in a 6-fold increase in [3H]thymidine incorporation. Similar doses also stimulated [3H]thymidine incorporation into rat lung fibroblasts by 6- to 8-fold. Removal of pulmonary surface active material by centrifugation did not significantly reduce the stimulatory activity of BALF for type II cells. The stimulation of type II cell DNA synthesis by BALF was reduced by 100% after heating at 100 degrees C for 10 min, and by approximately 80% after reduction with dithiothreitol, and after trypsin treatment. Dialysis of BALF against 1 N acetic acid resulted in a 27% reduction in stimulatory activity. The effect of BALF in promoting type II cell DNA synthesis was more pronounced when tested in the presence of serum, although serum itself has very little effect on type II cell DNA synthesis. When BALF was tested in combination with other substances that stimulate type II cell DNA synthesis (cholera toxin, insulin, epidermal growth factor, and acidic fibroblast growth factor), additive effects or greater were observed. When BALF was chromatographed over Sephadex G150, the activity eluted with an apparent molecular weight of 100 kDa

    We investigate the spectral properties of the UV (λλ2650–3050 Å) and optical (λλ4000–5500 Å) Fe ii emission features in a sample of 293 Type 1 active galactic nuclei (AGNs) from the Sloan Digital Sky Survey database. We explore different correlations between their emission line properties, as well as the correlations with other emission lines from the spectral range. We find several interesting correlations and outline the most interesting results as follows. (i) There is a kinematical connection between the UV and optical Fe ii lines, indicating that the UV and optical Fe ii lines originate from the outer part of the broad line region, the so-called intermediate line region. (ii) The unexplained anticorrelations of the optical Fe ii equivalent width (EW Fe ii{sub opt}) versus EW [O iii] 5007 Å and EW Fe ii{sub opt} versus FWHM Hβ have not been detected for the UV Fe ii lines. (iii) The significant averaged redshift in the UV Fe ii lines, which is not present in optical Fe ii, indicates an inflow in the UV Fe ii emitting clouds, and probably their asymmetric distribution. (iv) Also, we confirm the anticorrelation between the intensity ratio of the optical and UV Fe ii lines and the FWHM of Hβ, and we find the anticorrelations of this ratio with the widths of Mg ii 2800 Å, optical Fe ii, and UV Fe ii. This indicates a very important role for the column density and microturbulence in the emitting gas. We discuss the starburst activity in high-density regions of young AGNs as a possible explanation of the detected optical Fe ii correlations and intensity line ratios of the UV and optical Fe ii lines.

    Paraoxonase-1 is an esterase enzyme and it has 3 types of activity, namely paraoxonase, arylesterase, and diazoxonase. It has been reported that paraoxonase-1 deficiency is related to increased susceptibility to development of atherosclerosis and cardiovascular disease. The aim of this study was to investigate serum paraoxonase and arylesterase activities in children with iron deficiency anemia and vitamin B(12) deficiency anemia. Thirty children with iron deficiency anemia, 30 children with vitamin B(12) deficiency anemia, and 40 healthy children aged 6 months to 6 years were enrolled in this study. Serum paraoxonase and arylesterase activities were measured with a spectrophotometer by using commercially available kits. Mean paraoxonase and arylesterase activities in vitamin B(12) deficiency anemia group (103 ± 73 and 102 ± 41 U/L, respectively) were significantly lower than mean activities of control group (188 ± 100 and 147 ± 34 U/L, respectively; P .05). Paraoxonase and arylesterase activities significantly increased after treatment with vitamin B(12) in vitamin B(12) deficiency anemia; however, there were no significant changes in the activities of these enzymes after iron treatment in iron deficiency anemia group. Important correlations were found between vitamin B(12) levels and both paraoxonase and arylesterase activities (r = .367, P paraoxonase and arylesterase activities, and after vitamin B(12) therapy the activities of these enzymes returned to near-normal levels.

  11. Recognition of lysophosphatidylcholine by type II NKT cells and protection from an inflammatory liver disease.

    Lipids presented by the MHC class I-like molecule, CD1d, are recognized by NK T (NKT) cells, which can be broadly categorized into two subsets. The well-characterized type I NKT cells express a semi-invariant TCR and can recognize both α- and β-linked glycolipids, whereas type II NKT cells are less well studied, express a relatively diverse TCR repertoire, and recognize β-linked lipids. Recent structural studies have shown a distinct mode of recognition of a self-glycolipid sulfatide bound to CD1d by a type II NKT TCR. To further characterize Ag recognition by these cells, we have used the structural data and screened other small molecules able to bind to CD1d and activate type II NKT cells. Using plate-bound CD1d and APC-based Ag presentation assay, we found that phospholipids such as lysophosphatidylcholine (LPC) can stimulate the sulfatide-reactive type II NKT hybridoma Hy19.3 in a CD1d-dependent manner. Using plasmon resonance studies, we found that this type II NKT TCR binds with CD1d-bound LPC with micromolar affinities similar to that for sulfatide. Furthermore, LPC-mediated activation of type II NKT cells leads to anergy induction in type I NKT cells and affords protection from Con A-induced hepatitis. These data indicate that, in addition to self-glycolipids, self-lysophospholipids are also recognized by type II NKT cells. Because lysophospholipids are involved during inflammation, our findings have implications for not only understanding activation of type II NKT cells in physiological settings, but also for the development of immune intervention in inflammatory diseases.

    In a study on villagers settled on the outskirts of the Taurus Mountains and whose source of living is thyme, it was revealed that the villagers excessively consumed thyme by adding it to their tea and many of their foods; high incidences of anemia was found among these villagers. In this study, 42 male adult Wistar albino rats weighing 200-250 g were used. The rats were divided to six equal groups as follows: control, cholesterol (Chol), 80 mg/kg Origanum onites Labiatae (OOL), 80 mg/kg Thymbra spicata Labiatae (TSL), 80 mg/kg Satureja cuneifolia Labiatae (SCL), and 160 mg/kg TSL, and each group consisted of seven rats. The control group was fed with normal pellet feed. The Chol group and all the other groups, except for the control group, were fed with 2% cholesterol-containing pellet feed. Physiological serum of 4 ml was given to the control and Chol group, wheile 80 mg/kg of thymes tea was given to the OOL group, TSL group, and SCL group, and 160 mg/kg of thymes tea was given to the TSL group by means of a gavage for 30 days. In the blood samples, the hematologic parameters and the biochemical parameters of serum glucose, blood urea nitrogen, creatinine, total protein, albumin, iron (I), total iron-binding capacity, aminotransferase aspartate, alanine aminotransferase, alkaline phosphatase, lactate dehydrogenase, total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein cholesterol, triglyceride, and oxidized LDL levels were examined. The kidney and liver tissues were examined histopathologically. The results of the study showed that different types of thymes had an antihypercholesterolemic effect. In addition to the anemic effect detected in group TSL and the mild granular degeneration found in the liver of 80 mg/kg SCL group, distinct granular degeneration was observed in 160 mg/kg TSL group. © The Author(s) 2012.

    Anemia is one of the most common symptoms in children caused by numerous underlying diseases. In majority of patients, these diseases can be correctly diagnosed through physical examination, history taking, and routine laboratory tests. Bone marrow failure syndromes associated with several genetic diseases are rare causes of anemia in childhood. We reviewed the recent progress of molecular mechanisms in bone marrow failure syndromes, such as Shwachman-Diamond syndrome (SDS), Diamond-Blackfan anemia (DBA), and dyskeratosis congenita (DC), which are all predicted to involve defective ribosome synthesis. Delineation of the precise role of each gene product in ribosomal biogenesis and hematopoiesis may have both therapeutic and prognostic significance.

    Hypoproliferative anemia results from the inability of bone marrow to produce adequate numbers of red blood cells. The list of conditions that cause hypoproliferative anemia is long, starting from common etiologies as iron deficiency to rarer diagnoses of constitutional bone marrow failure syndromes. There is no perfect diagnostic algorithm, and clinical data may not always clearly distinguish “normal” from “abnormal”, yet it is important for practicing clinicians to recognize each condition so that treatment can be initiated promptly. This review describes diagnostic approaches to hypoproliferative anemia, with particular emphasis on bone marrow failure syndromes. PMID:26404444

  20. CD1d-Restricted Type II NKT Cells Reactive With Endogenous Hydrophobic Peptides.

    NKT cells belong to a distinct subset of T cells that recognize hydrophobic antigens presented by major histocompatibility complex class I-like molecules, such as CD1d. Because NKT cells stimulated by antigens can activate or suppress other immunocompetent cells through an immediate production of a large amount of cytokines, they are regarded as immunological modulators. CD1d-restricted NKT cells are classified into two subsets, namely, type I and type II. CD1d-restricted type I NKT cells express invariant T cell receptors (TCRs) and react with lipid antigens, including the marine sponge-derived glycolipid α-galactosylceramide. On the contrary, CD1d-restricted type II NKT cells recognize a wide variety of antigens, including glycolipids, phospholipids, and hydrophobic peptides, by their diverse TCRs. In this review, we focus particularly on CD1d-restricted type II NKT cells that recognize endogenous hydrophobic peptides presented by CD1d. Previous studies have demonstrated that CD1d-restricted type I NKT cells usually act as pro-inflammatory cells but sometimes behave as anti-inflammatory cells. It has been also demonstrated that CD1d-restricted type II NKT cells play opposite roles to CD1d-restricted type I NKT cells; thus, they function as anti-inflammatory or pro-inflammatory cells depending on the situation. In line with this, CD1d-restricted type II NKT cells that recognize type II collagen peptide have been demonstrated to act as anti-inflammatory cells in diverse inflammation-induction models in mice, whereas pro-inflammatory CD1d-restricted type II NKT cells reactive with sterol carrier protein 2 peptide have been demonstrated to be involved in the development of small vessel vasculitis in rats.

    Type II diabetes mellitus (DM), a common disease with many potential complications, is strongly associated with obesity. Alterations in food consumption can dramatically alter glucose control in individuals with Type II DM. Binge eating disorder (BED) is also closely associated with obesity. The nature of the relationship, if any, between Type II DM and BED is unclear. Forty-three individuals (23 females, 20 males) with Type II DM were assessed using the Structured Clinical Interview for DSM-IV (SCID-I), the Three-Factor Eating Questionnaire (TFEQ), and the Impact of Weight Scale. The most recent hemoglobin A1c level was recorded. Height and weight were also measured. Eleven subjects (25.6%) were diagnosed with BED. Individuals with BED had higher body mass index (BMI) scores, higher TFEQ Disinhibition and Hunger scores, and higher scores on all Impact of Weight subscales (except eating) compared with those without BED. Glycosylated hemoglobin levels did not differ between the two groups (8.1% vs. 8.4%; p = 0.553). Rates of BED in subjects with Type II DM were substantial. Other types of psychopathology were also common. Although glycosylated hemoglobin levels were similar in patients with and without BED, the presence of BED was associated with greater obesity. Assessment for BED is an important aspect of the management of patients with Type II DM. Copyright 2001 by John Wiley & Sons, Inc.

    Core-collapse supernova (SN) explosions expose the structure and environment of massive stars at the moment of their death. We use the global fitting technique of Pejcha & Prieto to estimate a set of physical parameters of 19 normal SNe II, such as their distance moduli, reddenings, 56Ni masses {M}{Ni}, and explosion energies {E}\\exp from multicolor light curves and photospheric velocity curves. We confirm and characterize known correlations between {M}{Ni} and bolometric luminosity at 50 days after the explosion, and between {M}{Ni} and {E}\\exp . We pay special attention to the observed distribution of {M}{Ni} coming from a joint sample of 38 SNe II, which can be described as a skewed-Gaussian-like distribution between 0.005 {M}⊙ and 0.280 {M}⊙ , with a median of 0.031 {M}⊙ , mean of 0.046 {M}⊙ , standard deviation of 0.048 {M}⊙ , and skewness of 3.050. We use a two-sample Kolmogorov-Smirnov test and two-sample Anderson-Darling test to compare the observed distribution of {M}{Ni} to results from theoretical hydrodynamical codes of core-collapse explosions with the neutrino mechanism presented in the literature. Our results show that the theoretical distributions obtained from the codes tested in this work, KEPLER and Prometheus Hot Bubble, are compatible with the observations irrespective of different pre-SN calibrations and different maximum mass of the progenitors.
