Assessment of Genetic Diversity across differentially adopted rice ecotypes
Sridevi, G1., Raju, B.R2., Mohankumar, M.V2* and Sheshshayee, M, S.
Electronic Journal of Plant Breeding , 2012,
Abstract: Rice is an important staple food and a rich source of carbohydrates for 90% of South and Southeast Asians. Geneticdiversity of naturally adopted upland lines along with few germplasm collections in Karnataka were studied basedon 13 SSR loci on chromosome 1. A total of 24 individuals belonging to 3 differentially adopted groups [Upland(8), landraces (8) and cultivated varieties (8)] had a moderate to high level of genetic variability at groups level withnumber of alleles ranging from 5 to 23 (average 11.5) and PIC from 0.51 to 0.94 (average 0.79). The heterozygosityvaried from 0.39 to as high as 0.70. Over all genetic diversity of 0.81 was revealed indicating a high level of geneticvariation among these individuals. At the similarity coefficient of 7, all the lines were clearly grouped in 3 clusters.All cultivated types grouped in one cluster (cluster 1) except Rasi and CTH 1 which were included in cluster 2 andcluster 3 respectively. Cluster 1 contained 9 cultivated genotypes, where as cluster 2 contained 11 land races andcluster 3 had 4 upland lines. Out of 4 upland lines one line (AC-35341) intermixed, with C1 and three lines (PS-229,JBT-37/4 and AC-35310) with C3. The study of SSR markers on chromosome 1 facilitated the classification of theselines according to their adaptability. The information about the genetics of these populations will be for specificchromosomes and will be very useful for rice breeding programs, especially for gene mapping and ultimately formarker assisted selection programs.
Improved diagnostic accuracy in patients with suspected appendicitis
B. B. Tingstedt1, R. Andersson2
Annals of Gastroenterology , 2007,
Abstract: Background: Studies during the 1990s showed that it was possible to reduce the rate of negative appendectomies by using various diagnostic methods. The present study aims to evaluate the effect on diagnostic accuracy of implementation of repeated clinical examination and blood tests in a small county hospital without possibilities of radiological assistance on a 24-hour basis. Methodology: Prospective study of all appendectomies performed at Ystad General Hospital, Sweden. Leukocyte count and C-reactive protein levels were analysed in all patients. Patients with suspicion of acute appendicitis were admitted for active observation, repeated clinical examination and analyses of leukocyte counts and CRP levels. Results: 533 appendectomies were performed during 1996- 2000 and compared with the index year 1995. Diagnostic accuracy increased from 73% to 90% (p<0.01). The rates of perforations and complications did not change during the study period, being 12.4% and 5.1%, respectively. Coinciding with the increased accuracy, a drop in the number of appendectomies performed and a longer time interval from admittance to the start of operation was seen. Conclusion: Through repeated clinical examinations and blood tests it was prospectively possible to achieve an increase in diagnostic accuracy in patients with suspicion of acute appendicitis without any noticeable side effects.

Physics , 2007,
Abstract: We propose a robust spectral beam combining scheme using wavelength dependent polarisation rotators and polarization beam combiners. We successfully demonstrated the concept for two Yb-doped fiber lasers at 1064nm and 1092nm up to a total input power of 90W. The results reveal a very good combining efficiency and the potential for scaling to high power operations in this method of beam combining.

Abstract: El presente trabajo se desarrolló con el objetivo de evaluar el comportamiento agronómico de siete accesiones de Brachiaria humidicola durante la fase de establecimiento, para seleccionar aquellas de mejor adaptación a las condiciones de suelo ácido y de baja fertilidad de la región Santandereana de Barrancabermeja y Magdalena Medio, Colombia. Se emplearon 21 parcelas, con un dise o completamente aleatorizado y tres réplicas para cada accesión. Las evaluaciones se realizaron a partir del séptimo día de plantadas las semillas y las parcelas se consideraron establecidas cuando el área cubierta alcanzó el 80%. Se determinó la emergencia, la cobertura, la altura, el desplazamiento lateral, la producción de forraje seco, la incidencia de plagas y enfermedades y las deficiencias nutricionales de las plantas; además se realizó el análisis bromatológico. Las accesiones de B. humidicola tuvieron una germinación promedio de 30%. La varianza acumulada fue de 88,67% en las tres primeras componentes. Se concluye que la variabilidad total fue alta, en función de los indicadores medidos y/o estimados, lo que permitió la diferenciación adecuada de las accesiones. Los indicadores de mayor contribución en la formación de los grupos y en la selección fueron: la cobertura, la materia seca, la producción de forraje seco, el porcentaje de grasa, la hojosidad, la energía y la proteína. The objective of this work was to evaluate the agronomic performance of seven Brachiaria humidicola accessions during the establishment stage, in order to select those with better adaptation to the conditions of acid soil and low fertility of the Santander region of Barrancabermeja and Magdalena Medio, Colombia. Twenty-one plots were used, with a completely randomized design and three replications for each accession. The evaluations were made since the seventh day after the seeds were planted and the plots were considered established when the covered area reached 80%. The emergence, cover, height, lateral displacement, dry forage production, incidence of pests and diseases and nutritional deficiencies of the plants were determined; the bromatological analysis was also made. The B. humidicola accessions had an average germination of 30%. The cumulative variance was 88,67% in the first three components. The total variability was concluded to be high, with regards to the measured and/or estimated indicators, which allowed the adequate differentiation of the accessions. The indicators of higher contribution in group formation and selection were: cover, dry matter, dry forage production, fat percent

Bioscience Discovery , 2012,
Abstract: Cressa cretica L. belonging to family Convolvulaceae, commonly known as Boknu is a erect, small, dwarf shrub, usually grows in sandy or muddy saline habitats. Brew baker and Kwack's basal medium was used for germination of pollen grains. At low concentration (5% and 10%) of water extract of Cressa cretica plant (WEC) reported minimum inhibitory effect i.e., 57.84% 42.78% respectively on in vitro pollen germination of Cajanus cajan. The maximum reduced pollen germination was observed under 75% concentration of leaf extract (8.69%) and pollens were no germinated on 100% of WEC as compared to control (70%) after 15 minutes. The aerial parts of Cressa cretica L. yielded five flavonoids that were identified.

Abstract: Human brucellosis is common in developing countries and a multi-system disease with a broad spectrum of clinical manifestations. Cutaneous lesions associated with brucellosis have been rarely reported in the world literature. Here we present the case of a 69-year-old woman with history of consumption of cheese made from raw milk seen with occurrence of thrombocytopenia and diffuse maculopapular rash during the course of Brucella infection. Physical examination showed a pruritic maculopapular exanthema over the trunk, arms and legs. Laboratory tests revealed severe thrombocytopenia with platelet count of 15x109/L. Body temperature was normal. Parasitic examinations and serologic tests for syphilis, salmonellosis, rickettsiae, toxoplasma, Epstein-Barr virus, human immunodeficiency virus, and hepatitis B and C viruses were negative. The Brucella agglutination test titer was 1/2.560 and the skin lesions were interpreted as brucellar dermatitis. The patient was subsequently treated with oral doxycycline and rifampicin and was discharged in good health. If there is suspicion of exposure to infected food products, brucellosis should be included in the differential diagnosis of thrombocytopenia in Brucella-endemic areas; there may be skin lesions other than purpura that can accompany thrombocytopenia.

Abstract: The study was conducted to evaluate the effect of intervention of skim milk based functional drink supplemented with 100 mg of soy isoflavone and 8 mg of Zn-sulfate (susumeno) on serum estradiol and thymulin hormones levels of permenopausal women. After 2 month of intervention, the estradiol levels did not change, and the levels were in the range of 39,16 – 41,99 pg/ml. However the thymulin hormone levels increased significantly from 2,37 μg/ml to 3,31 μg/ml. Increase in thymulin levels shows that the disfuction of immune system of premenopausal could be improved by the functional drink.

Abstract: There has been limited report on the phytochemical content of cassia vera bark extract, and its potency as anti-hypercholesterolemic in rabbit is not known yet. The objectives of this research was to determine the phytochemical content and potency of anti-hypercholesterolemic of cassia vera bark extract using rabbit as the animal model.The research was devided into three stages, namely: (1) preparing cassia vera extraction with ethanol 96%; (2) analyzing phytochemical contents of cassia vera bark extract; (3) in vivo experiment, where twenty New Zealand White rabbits aged 5 months were used. Experimental rabbits were divided into 5 groups. The rabbits were fed with atherogenic cholesterol (0.1%) as positive control, RB11 standard feed as negative control, or cassia vera extracts (100 mg/kg/day or 200 mg/kg/day) or fenofibrat (15 mg/day) together with the atherogenic feed for 12 weeks. Levels of serum total cholesterol, triglyceride, HDL-cholesterol and LDL-cholesterol were determined at 0, 4, 8, and 12 week. At the end of the experiment formation of fatty liver were observed. The results showed that the ethanol extract of cassia vera bark contains total phenol (62.25%), flavonoids, triterpenoid, saponin and alkaloid. On the other hand, cassia vera bark extract was able to decrease total serum cholesterol from 443.3 mg/dl to 139.1 mg/dl, LDL cholesterol from 286.5 mg/dl to 95.8 mg/dl and triglyceride from 122.2 mg/dl to 61.2 mg/dl. Meanwhile, it increased HDL serum cholesterol from 29.1 mg/dl to 50.0 mg/dl in rabbit. It was also shown that the extract was able to decrease the everage fat globule on liver significantly from 27.47 globule to 3.59 globule per field view. Cassia vera bark extract with phytochemical content was found to be potential as anti-hypercholesterolemic and also in preventing fatty liver formatonr in rabbit

Abstract: In this study, data on productive and reproductive records of 100 local and Holstein Friesian crossbred cows were analyzed for three different zones of Bannu division, NWFP. The crossbred cattle were the product of crossbreeding over the last 10 years, usually containing 50 to 75% exotic blood. The mean age at puberty was 74 3 ± 51 days and ranged from 410 to 1110 days. Age at puberty in local cow was 878.7 days, while in Holstein Friesian crossbred cows it was 610.3 days (P<0.0 1), The cows showed shortest age at puberty in irrigated area, followed by rainfed and hilly areas, The crossbred cows showed shortest age at puberty in rainfed area followed by irrigated and hilly areas. Mean age at first calving was 1106 ± 76.4 days, ranging from, 780 to 1490 days. The cattle showed shortest age at first calving in rainfed area, followed by irrigated and hilly areas (P<0.01). Mean for services per conception was 2 ± 0.1, ranging from 1 to 4. The value was 1.0 in local cattle and 1.05 in crossbreds. The number was slightly shorter in the hilly area than the irrigated and rainfed areas, Conception rate in crossbred cows was 15, 61 and 23% with first, second and third insemination, while in local cattle the mean was 14, 70 and 16%. Mean calving interval was 405 ± 29 days, ranging from 315 to 550 days. Calving interval in local cows was 4 18 days, while in Holstein Friesian crossbreds it was 390 days (P<0.05). The calving interval was longest in the irrigated area followed by rainfed and hilly areas (P<0.05). Mean dry period was 122 ± 5.3 days, ranging from 60 to 370 days. The dry period in local and Holstein Friesian crossbred cattle was 152.6 and 89.3 days, respectively (P<0.01). Average milk production was 6 ± 0.4 liters/day, ranging from 3 to 12 liters/day. The average milk recorded in local cows was 4.76 liters day and in crossbred cows it was 7.13 liters/day (P< 0.01). The cows showed highest milk yield in irrigated area, followed by rainfed and hilly areas (P< 0.01). Mean lactation length was 293 ± 23.3 days, ranging from 200 to 480 days. The length was 338.3 days in crossbred cattle and 249.8 days in local cattle (P<0.0 I). The cattle showed highest lactation length in hilly area, followed by rainfed and irrigated areas ( P< 0.01 ). Correlation analysis of the data showed that services per conception were not affected by any reproductive trait or milk yield. However, calving interval was correlated positively and significantly with age at puberty and age at first calving, lactation length, dry period and average milk production (r=0.27, 0.13, 0.35, 0.15 an
