Genetic analysis of yield and heat stress related traits in wheat (Triticum aestivum L. em. Thell) using microsatellite markers

Microsatellite markers were used for genetic analysis of terminal heat tolerance in F2 (PBW373 × WH1081) population of wheat (Triticum aestivum L. em. Thell). Two parents were evaluated in field under normal sown and late sown conditions. For genotyping DNA from both parents PBW373 and WH1081 was amplified using 200 SSRs. Only 22 SSRs produced polymorphic bands, of size between 100 to 300 bp and an average of 1.45 alleles. The single marker analysis identified 19 markers indicating the putative QTLs for yield, its components and heat stress related physiological traits. The number of markers on these 16 linkage groups varied from one to four. On A genome 13 QTLs on B genome 5 QTLs and on D genome 9 QTLs were identified, respectively. The A, B and D genomes had 1360.3 cM, 272.4 cM and 919.5 cM of linkage coverage with average interval distances of 104.63 cM, 54.48 cM and 102.16 cM/Marker. A total of nine QTLs were resolved following composite interval mapping, one QTL was detected at a LOD score equal to threshold value of 2.5 while eight at LOD scores above the threshold value. All the nine QTLs were shown to be on definitive location on chromosome 3A (QDh.CCSHAU-3A, QDa.CCSHAU-3A and QPm.CCSHAU-3A), chromosome (QBm.CCSHAU-5A, QCtd.CCSHAU-5A and QCl.fl.CCSHAU-5A), chromosome6A (QPh.CCSHAU-6A) and chromosome3B (QTgw.CCSHAU and QMts.CCSHAU-3B). Use of these markers save times, resources and energy that are needed not only for raising large segregating populations for sveral generations, but also for estimating the parameters used for selection

Reaction of tetrasodiumcalix(4)arene sulphonate with transition metal(III) nitrates (metal = Cr, Co & Fe)

746-749Reaction of tetrasodiumcalix(4)arene sulphonate (TSCS) with metal(Ill) nitrates (metal = Cr, Co and Fe) provides a good yield of the corresponding complexes, viz., [Cr(OH2)6][Na][TSCS] (acetone).10.5H2O, [Co(OH2)6[Na][TSCS].7.5 H2O and [Fe(OH2)6[Na][TSCS}.1OH2O. The new complexes have been characterized by elemental analyses, magnetic susceptibility measurements, IR and electronic spectral data

An unusual presentation of sclerosing mesenteritis as pneumoperitoneum: Case report with a review of the literature

Sclerosing mesenteritis is a rare condition that involves the small or large bowel mesentery. An unusual presentation of this condition, which led to difficult preoperative assessment and diagnosis, is described. This report is followed by a comprehensive review of the literature

α-Fetoprotein in Indian childhood cirrhosis

Of forty-two children with Indian childhood cirrhosis nineteen (45%) α-fetoprotein (A.F.P.) in the serum by the gel-diffusion technique, even when they were older than 1 year. This seems to be the first record of a disease other than hepatoma or teratocarcinoma showing persistence or reappearance of A.F.P. in such a high proportion of individuals. The possibility that the presence of A.F.P. in these children indicates an inherent developmental defect of the liver cell needs elucidation

Primary prophylaxis of gastroesophageal variceal bleeding: consensus recommendations of the Asian Pacific Association for the study of the liver

The Asian Pacific Association for the Study of the Liver (APASL) set up a Working Party on Portal Hypertension in 2002, with a mandate to develop consensus guidelines on various clinical aspects of portal hypertension relevant to disease patterns and clinical practice in the Asia-Pacific region. Variceal bleeding is a consequence of portal hypertension, which, in turn, is the major complication of liver cirrhosis. Primary prophylaxis to prevent the first bleed from varices is one of the most important strategies for reducing the mortality in cirrhotic patients. Experts predominantly from the Asia-Pacific region were requested to identify the different aspects of primary prophylaxis and develop the consensus guidelines. The APASL Working Party on Portal Hypertension evaluated the various therapies that have been used for the prevention of first variceal bleeding. A 2-day meeting was held on January 12 and 13, 2007, at New Delhi, India, to discuss and finalize the consensus statements. Only those statements that were unanimously approved by the experts were accepted. These statements were circulated to all the experts and were subsequently presented at the annual conference of the APASL at Kyoto, Japan, in March 2007
