The influence of the developmental stage of microspores on establishing isolated microspore cultures of three Hungarian (‘Szegedi
80’, ‘Szegedi 178’, and ‘Remény’) and three Spanish (‘Jeromin’, ‘Jariza’, and ‘Jaranda’) pepper genotypes was investigated.
Donor anthers containing 80% uninucleated and 20% binucleated microspores yielded the highest frequency of successful microspore
cultures. Co-cultures with wheat, line ‘CY-45’, ovaries exhibited enhanced frequency of embryoid production than those with
pepper ovaries. Differences in efficiency of isolated pepper microspore culture establishment were observed among different
pepper genotypes. Green plantlets were regenerated from microspore-derived embryoids, but some were exhibited abnormal growth
habits, such as leaf rosetting. A total of seven fertile microspore-derived plants were obtained, including three ‘Jariza’,
three ‘Jaranda’, and a single ‘Szegedi 80’ plant. 相似文献

The objective of the present study is to calculate linear regressions between a mother and her child with respect to their
selenium concentration (ng/g) in the following traits: maternal blood and umbilical cord blood, maternal and child hair, maternal
milk and child umbilical cord blood, maternal milk and meconium, maternal blood plasma, and child meconium. The data were
collected at Research Hospital of the University of Yüzüncü Yıl from 30 pairs of mothers and their newborn baby. The mean
maternal serum Se level in 30 mothers was 68.52 ± 3.57 ng/g and cord plasma level was 119.90 ± 18.08 ng/g. The Se concentration
in maternal and neonatal hair was 330.84 ± 39.03 and 1,124.76 ± 186.84 ng/g, respectively. The Se concentration of maternal
milk at day 14 after delivery was determined as 68.63 ± 7.78 ng/g (n = 13) and the concentration of Se was 418.90 ± 45.49 ng/g (n = 22) for meconium of neonatal. There was no significant difference between maternal blood and milk Se levels. However, hair
Se concentration was significantly higher than milk and maternal blood Se level. For each trait comparison, the average absolute
difference in log10-transformed Se concentration was calculated between a mother and her child. The observed average absolute difference was
compared with a test distribution of 1,000 resampled bootstrap averages where the number of samples was maintained but the
relationship between a mother and her child was randomized among samples (α = 0.05). 相似文献

Hygraula nitens is a New Zealand native moth with aquatic larvae that feed on submerged aquatic plants. The larvae have been mainly observed using native Potamogeton and Myriophyllum species as a food source, although some studies reported larvae feeding on the alien macrophytes Hydrilla verticillata, Lagarosiphon major and Ceratophyllum demersum. Experimental mesocosm studies showed larvae had a major effect on H. verticillata, C. demersum, L. major, Elodea canadensis and Egeria densa. In both no choice and choice experiments H. nitens larvae showed a clear preference for and the highest consumption of C. demersum, while the native macrophyte Myriophyllum triphyllum ranked fourth out of five alien and two native plant species, indicating a preference of the larvae for alien macrophytes. Additional choice experiments using C. demersum, sampled from different waters in NZ, illustrated that there was a clear difference in H. nitens preference for plants based on their source. However although C. demersum had the lowest leaf dry matter content (LDMC) compared with the other macrophytes, neither the LDMC nor leaf carbon, nitrogen, phosphorus or total phenolic contents alone could explain the preferences of H. nitens, and we conclude that food choice is based on a combination of these and/or additional factors. 相似文献

We introduce the first meta-service for information extraction in molecular biology, the BioCreative MetaServer (BCMS; http://bcms.bioinfo.cnio.es/). This prototype platform is a joint effort of 13 research groups and provides automatically generated annotations for PubMed/Medline abstracts. Annotation types cover gene names, gene IDs, species, and protein-protein interactions. The annotations are distributed by the meta-server in both human and machine readable formats (HTML/XML). This service is intended to be used by biomedical researchers and database annotators, and in biomedical language processing. The platform allows direct comparison, unified access, and result aggregation of the annotations. 相似文献

Chloroform concentrations were observed and input and output fluxes estimated over a 2-yr period in a small coniferous catchment
(0.22 km2) in southeast Sweden. Water discharge was measured daily, and runoff water was sampled bi-weekly for chloroform analysis.
An approximate chloroform budget was calculated, which indicated that the annual output of 6 μg m−2 yr−1 was approximately six times higher than the input, inferring an internal source of chloroform in the catchment. To the best
of our knowledge, neither flux estimates nor mass balances have previously been made for chloroform on a catchment scale,
nor have data regarding natural runoff variation with time been gathered. Concentrations of chloroform in runoff were found
to be generally high during wet periods, such as spring, but also peaked during summer rain events. The observed pattern suggests
that chloroform is formed in surface soil layers and transported to the outlet under high-flow conditions and during dry-period
rain events; it is lost through degradation or evaporation during drier periods due to longer soil water residence times.
The data suggest that the variation among replicates increases with concentration; this emphasizes the need to know what the
degree of on-site variation is, so one can collect a sufficient number of replicates to permit detection of spatial or temporal
changes. 相似文献

Background
Factor XI (FXI) is a plasma protein that participates in the formation of blood clots. Factor XI deficiency is autosomal recessive hereditary disorder that may be associated with excess bleeding in Holstein cattle. 相似文献157.

Background
A single prolonged milking interval (PMI) e.g. after a technical stop in an automated milking system is of concern for the producer since it is associated with a short-lasting increase in milk somatic cell count (SCC), which is a major quality criterion used at the dairy plants. The content of polymorphonuclear leukocytes (PMN) and how the milk quality is influenced has not been much investigated. The SCC peak occurs without any obvious antigen challenge, possibly indicating a different leukocyte attraction mechanism after a PMI than we see during mastitis. 相似文献158.
A double-blind, placebo-controlled clinical trial of a homeopathic treatment of neonatal calf diarrhoea was performed using
44 calves in 12 dairy herds. Calves with spontaneously derived diarrhoea were treated with either the homeopathic remedy Podophyllum
(D30) (n = 24) or a placebo (n = 20). No clinically or statistically significant difference between the 2 groups was demonstrated.
Calves treated with Podophyllum had an average of 3.1 days of diarrhoea compared with 2.9 days for the placebo group. Depression,
inappetence and fever were presented equally in the 2 groups. These results support the widely held opinion that scientific
proof for the efficacy of veterinary homeopathy is lacking. In the European Union this implies a considerable risk for animal
welfare, since in some countries priority is given to homeopathic treatments in organic farming. 相似文献
