A Review :Implementation of Reed Solomon Error Correction & Detec-tion For Wireless Network 802.16
The reed Solomon (255,239) are error-correcting & detecting code. Reed-Solomon codes are the most frequently used digital error control. It is also called as forword error code. The main part of reed-Solomon encoder is the linear feedback shift register that is implemented using VHDL A pipelined RS decoders is proposed of reducing the hardware complexity use the pipelined GFmultiplier in the syndrome computation block, KES block, Forney block, Chien search block and error correction block for provides low com-plexity the extended inversion less Massey-Berlekamp algorithm is used. The extended inversion less Massey-Berlekamp algorithm overcomes both the error locator polynomial and the error evaluator polynomial at the same time
CORRELATION OF NUTRITIONAL STATUS OF MOTHER AND THE BIRTH WEIGHT OF THE BABY
Objective: The objective of this study is to correlate mother's nutritional status during pregnancy and determine the birth weight of the baby.Methods: A comparative, exploratory approach and prospective cohort study design was used to find out mothers' nutritional status during pregnancy influences the birth weight of babies. The data were collected using structured interview schedule and dietary history by 24 h recall method from a randomly selected sample of 380 eligible mothers delivered at Krishna Hospital, Karad.Results: There was a significant correlation between birth weight and calorie intake (correlation coefficient [r]=0.595; p<0.001; Chi-square=201.3; p<0.001.) A higher proportion of low birth weight babies, i.e., 105 (32.2%) were delivered by the mothers consuming <70% of protein ([r]=0.245; p<0.001; χ2=24.033; p<0.001]). There was correlation between birth weight and calcium intake of mothers ([r]=0.525; p<0.001; χ2=10.12; p<0.001] birth†weight and iron intake of mothers ([r]=0.250; p<0.001; χ2=13.798; p<0.001).Conclusion: The intake of calorie, protein, calcium, and iron of mother can significantly influence the weight of the newborn baby. Among all anthropometric parameters of the mother, weight gain was the strongest predictor of adequacy of the birth weight
Seed size and its influence on germination, seedling growth and biomass in Saraca asoca (Roxb). De Wilde, critically endangered tree species of Western ghats, India
Saraca asoca (Roxb). De Wilde is one of the high traded medicinal plant species of India. There is a huge demand for bark of this species both in domestic and international markets. There is a demand for quality planting materials for large scale plantation. Forest department and farmers have already initiated captive plantation of this species. Several factors affect the seedling quality in nursery. Seed grading is one among them. The present study aims at understand the influence of seed size on seed germination and seedling vigour in S. asoca. Association study showed that seed length was positively correlated with seed weight (r= 0.887), seed width (r=0.697) and thickness (r=0.621). Therefore, seed length was used to categorize seedlot into small (< 30.0 mm), medium (30.1-40.0 mm) and large (> 40.1 mm) seeds. Result showed that larger seeds produced maximum germination (86.7%) as compared to smaller seeds (45.0%). Moreover, larger seeds attained higher collar diameter (3.34 mm) and dry biomass viz., leaf biomass (0.91 g), shoot biomass (0.31 g), root biomass (0.95 g) and entire seedling biomass (2.17 g) as compared to smaller seeds. Seedlings raised from medium seeds were at par with larger seeds in most of the traits. Therefore, it is suggested to use seedlot having > 30 mm length, preferably larger seeds (> 40 mm) in the nursery for better establishment of quality seedlings
Seed traits, germination pattern and seedling vigour in Antiaris toxicaria (Pers.) Lesch., a rare plant species of Western ghats
Antiaris toxicaria (Pers.) Lesch. is one of the species of ecological importance distributed in Western Ghats and other parts. This species is considered as one of the threatened species and it needs conservation. The information on fruit and seed trait variation and germination attributes are scanty. Such database is useful for afforestation programme as well as for augmentation of rare plant species in their natural habitat. For the present study, 10 open pollinated trees distributed in Devade forest of Sakharpa were marked. April month was the peak fruiting period and healthy fruits were collected from the ground. Fruit and seed traits were found to be varied significantly among trees, where fruit length ranged from 21.50 to 24.71 mm and fruit weight ranged from 3.64 to 4.07 g. Similarly, seeds length (14.01 -15.09 mm), seed thickness (12.15 -13.04 mm) and seed weight (1.20 – 1.57g) also showed significant variation among 10 trees. Field observation showed that there was a poor regeneration in this species at studied site. Therefore, germination study was conducted at nursery condition by imposing several pretreatments. Among eight treatments including control, soaking seeds in water for 24 hrs (T2) resulted in better germination of 38.0% as compared to others. In T2 seed germination started at 16 days after sowing and completed within 42 days. Potting mixture of red soil with saw dust in 30:70 ratio improved seed germination about 20 % as compared to red soil media
Association of Urine Levels of C-Reactive Protein with Clinical Outcomes in Patients with Pneumonia: A Pilot Study
Finding relevant biomarkers as a potential predictor of severity for patients hospitalized with community acquired pneumonia (CAP), in addition to the clinical scoring system, could advance progress towards more effective patient management. The inflammatory marker, C-reactive protein (CRP), which is elevated in the pathogenesis of many infectious diseases, may be a key biomarker target for CAP. Previous studies have shown that serum CRP may be a useful diagnostic marker for pneumonia in hospitalized patients with acute respiratory symptoms. The main aims of this study were to determine the correlation between serum and urine CRP levels in hospitalized patients with CAP, and any correlation with patient outcomes. Our laboratory employed a commercially available human high sensitive CRP ELISA kit to check the level of CRP in the corresponding patient urine sample. The results showed that there was a positive correlation between patient serum and urine CRP levels. In addition, we showed the correlation of urine CRP levels with certain patient comorbidities, time to clinical stability, length of patient hospital stay, and mortality
Assessment of risk factors and its fetal outcome of preterm birth: in rural tertiary care hospital, Karad, Maharashtra
Background: Preterm birth is an alarming cause of complication in pregnancy that leads to an immenseburden for imitation of children to their householders and health care providers. The present study was tofind out the functional relationship of preterm birth (PTB) and its study parameters at the Krishna Hospitaland Medical Research Centre Karad, Maharashtra from 2016–17. In SPSS (20.0), IBM, INDIA, multipleregression method was used to analyze the results.Methods: This was cross-sectional study done at rural tertiary care hospital, Karad. The examination wasdone in the ob-gyn. ward and various details were collected in the form of the questionnaire at presentthat ward with support of oral discussion of that patient.Results: Age and many more demographic variables were significantly associated with its fetal outcome ofpreterm birth. Also, it seems that pregnancy-induced hypertension, placenta diameter; numbers of meals,delivery mode, and those reasons were effective measures of risk factors of assessment of preterm birth.Conclusions: All the variables analyzed in this study were the part of the determinants of PTB needsto check time to time during the period of pregnancy. Heath care providers still need to take efforts forpregnancy-induced hypertension, placenta diameter
Characteristics and Clinical Outcomes of Hospitalized Patients with Community-Acquired Pneumonia who are Active Intravenous Drug Users
Background: Intravenous drug users (IVDU) have a 10-fold increased risk of community-acquired pneumonia (CAP) compared to the general population. There is scarce data available evaluating the clinical outcomes of IVDU hospitalized patients with CAP and that data mostly focuses on mortality. The objective of this study was to evaluate the clinical characteristics, incidence and outcomes of hospitalized patients with CAP in active intravenous drug users in Louisville, Kentucky.
Methods: This was a secondary data analysis of the University of Louisville Pneumonia study. IVDU patients were propensity score matched to a non-IVDU group. Study outcomes were time to clinical stability (TCS), length of stay (LOS), mortality at discharge, and mortality at 1 year. Stratified Cox proportional hazard regression was performed to evaluate TCS and LOS. Conditional logistic regression was performed to evaluate mortality. Statistical significance was defined as p ≤ 0.05.
Results:From a total of 8,284 hospitalized patients with CAP reviewed, 113 patients were matched per group. Median (IQR) age for the IVDU was 33 (28-43) versus 36 (28-48) for the matched non-IVDU group (p
Conclusions: This study shows that active IVDU hospitalized patients with CAP do not have worse outcomes when compared with non-IVDU hospitalized patients with CAP. Patients in the IVDU group were significantly younger. Since severity scores commonly used are heavily influenced by age, these will not likely be useful tools to assist the physicians with the site for care and management
Doc2b Protects β-Cells Against Inflammatory Damage and Enhances Function
Loss of functional β-cell mass is an early feature of type 1 diabetes. To release insulin, β-cells require soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) complexes, as well as SNARE complex regulatory proteins like double C2 domain-containing protein β (Doc2b). We hypothesized that Doc2b deficiency or overabundance may confer susceptibility or protection, respectively, to the functional β-cell mass. Indeed, Doc2b+/- knockout mice show an unusually severe response to multiple-low-dose streptozotocin (MLD-STZ), resulting in more apoptotic β-cells and a smaller β-cell mass. In addition, inducible β-cell-specific Doc2b-overexpressing transgenic (βDoc2b-dTg) mice show improved glucose tolerance and resist MLD-STZ-induced disruption of glucose tolerance, fasting hyperglycemia, β-cell apoptosis, and loss of β-cell mass. Mechanistically, Doc2b enrichment enhances glucose-stimulated insulin secretion (GSIS) and SNARE activation and prevents the appearance of apoptotic markers in response to cytokine stress and thapsigargin. Furthermore, expression of a peptide containing the Doc2b tandem C2A and C2B domains is sufficient to confer the beneficial effects of Doc2b enrichment on GSIS, SNARE activation, and apoptosis. These studies demonstrate that Doc2b enrichment in the β-cell protects against diabetogenic and proapoptotic stress. Furthermore, they identify a Doc2b peptide that confers the beneficial effects of Doc2b and may be a therapeutic candidate for protecting functional β-cell mass
Clinical Outcomes for Patients with Community-Acquired Pneumonia are Worse in Those with a History of Stroke
Background: Stroke is one of the most prevalent neurological diseases in the United States. Community-acquired pneumonia (CAP) is the leading cause of infections in survivors of stroke. There is limited research evaluating the clinical outcomes of CAP in patients with stroke. The objective of this study was to evaluate the clinical characteristics and outcomes of hospitalized patients with CAP and a history of stroke.
Methods: This was a secondary analysis of the University of Louisville Pneumonia Study database. Patients were divided into two groups based on the presence or absence of a history of stroke. Clinical outcomes were length of stay, time to clinical stability, and one-year mortality, which were assessed via stratified Cox proportional hazards regression. Differences in risk of clinical outcomes were reported as adjusted hazard ratios.
Results: We found no significant differences in time to clinical stability between the two groups. The median length of stay for patients with a history of stroke hospitalized with CAP was six days and for patients without stroke was five days (P=0.01). We observed a 16% higher risk of mortality in stroke patients with CAP than in the non-stroke population (P=0.001).
Conclusions: This study indicates that hospitalized patients with CAP have a longer hospital stay and higher mortality than those without stroke
COVID-19 is Associated with Increased Severity in Pregnant Women
Background: COVID-19 pandemic originated in China in late 2019, the number of cases are increasing with 2,104,346 cases and 116,140 deaths in the United States, as of June 16, 2020. Pregnant women are a vulnerable population in epidemics or Pandemics. This Review is designed to look in detail the severity of COVID-19 in pregnant women in comparison to non-pregnant women of reproductive age.
Methods: Literature search on PubMed, Google Scholar, Lancet, and Web of Science were conducted.
Results: We have found the evidence of increased risk for severe disease and distinctive symptoms among pregnant women diagnosed with COVID-19 as compared to non-pregnant women.
Conclusions: COVID-19 presents in an atypical fashion in pregnant women with comparatively increased severity of symptoms, compared to COVID-19 positive non pregnant women of reproductive age. These findings can help clinicians to recognize the risk posed by COVID-19 in pregnant women
