Haemoglobin and Albumin Polymorphisms in Indian Water Buffaloes     

N. D. Khanna  M. Brsend 《Acta veterinaria Scandinavica》1968,9(4):316

A total of 507 samples from the Murrah breed of Indian water buffalo were examined for haemoglobin and albumin polymorphism using starch gel electrophoresis. The majority of samples showed the same two band haemoglobin phenotype, A₁A₂, where the fastest band A₁ was about 67 % of total haemoglobin. Two rare phenotypic haemoglobin variants were observed. The one, found in four animals, had three bands and is explained by mutation in the β chain. The other, found in two animals, showed another relationship between the A₁ and A₂ bands than the common type and is assumed to be caused through heterozygosity at a modulating locus. Three albumin phenotypes were observed. Family data were in agreement with these being controlled by two codominant alleles, called Al^F and Al^s. Frequency of Al^F was 0.09 and 0.29 in two different populations. Age and sex did not have any effect on distribution of albumin phenotypes.  相似文献   

Comparative oncology today.     

Melissa C Paoloni  Chand Khanna 《Veterinary Clinics of North America: Small Animal Practice》2007,37(6):1023-32; v

The value of comparative oncology has been increasingly recognized in the field of cancer research, including the identification of cancer-associated genes; the study of environmental risk factors, tumor biology, and progression; and, perhaps most importantly, the evaluation of novel cancer therapeutics. The fruits of this effort are expected to be the creation of better and more specific drugs to benefit veterinary and human patients who have cancer. The state of the comparative oncology field is outlined in this article, with an emphasis on cancer in dogs.  相似文献

The aim of the Third International Workshop on Swine Leukocyte Differentiation Antigens (CD workshop), supported by the Veterinary Immunology Committee (VIC) of the International Union of Immunological Societies (IUIS), was to standardize the assignment of monoclonal antibodies (mAb) reactive with porcine leukocyte differentiation antigens and to define new antibody clusters, using nomenclature in accordance with human and ruminant CD nomenclature, as agreed at the summary meeting of the Second International Swine CD Workshop in Davis, 1995: only mAb with proven reactivity for the orthologous porcine gene product or cross-reactivity for the human gene products, were given the full CD nomenclature, all other allocations were prefixed with "w". As in previous workshops, the overall organization was entrusted to the chair and first author, with support by the chair of the previous workshop and second author. In addition to the existing 26 pig leukocyte CD/SWC determinants established in previous workshops, this workshop established/confirmed another 11 CDs for pig leukocytes, identified by a total of 21 mAb: CD11R1 (2 mAb), CD11R2 (1 mAb), CD11R3 (4 mAb), wCD40 (1 mAb), wCD46 (4 mAb), wCD47 (3 mAb), wCD49d (1 mAb), CD61 (1 mAb), wCD92 (1 mAb), wCD93 (1 mAb) and CD163 (2 mAb).  相似文献   

Al cluster superatoms as halogens in polyhalides and as alkaline earths in iodide salts     

Bergeron DE  Roach PJ  Castleman AW  Jones NO  Khanna SN 《Science (New York, N.Y.)》2005,307(5707):231-235

Two classes of gas-phase aluminum-iodine clusters have been identified whose stability and reactivity can be understood in terms of the spherical shell jellium model. Experimental reactivity studies show that the Al13I-x clusters exhibit pronounced stability for even numbers of I atoms. Theoretical investigations reveal that the enhanced stability is associated with complementary pairs of I atoms occupying the on-top sites on the opposing Al atoms of the Al13- core. We also report the existence of another series, Al14I-x, that exhibits stability for odd numbers of I atoms. This series can be described as consisting of an Al14I-3 core upon which the I atoms occupy on-top locations around the Al atoms. The potential synthetic utility of superatom chemistry built upon these motifs is addressed.  相似文献   

The flavonoid naringenin enhances intercellular colonization of rice roots by<Emphasis Type="Italic"> Azorhizobium caulinodans</Emphasis>     

Veena?JainEmail author  Kaushalya?Gupta 《Biology and Fertility of Soils》2003,38(2):119-123

The intercellular colonization of rice roots by Azorhizobium caulinodans and other diazotrophic bacteria has been studied using strains marked with the lacZ reporter gene. A. caulinodans were able to enter the roots of rice at emerging lateral roots (lateral root cracks) by crack entry and this was observed by light microscopy. After colonization of lateral roots, bacteria moved into intercellular space within the cortical cell layer of roots. Naringenin at 1×10^-5 and 5×10^-5 M concentration significantly enhanced root colonization. The role of nodABC and regulatory nodD genes was also studied; lateral root crack (LRC) colonization of rice was shown to be Nod factor and NodD independent. Lateral root crack colonization of rice was also observed with similar frequency following inoculation with Azospirillum brasilense and the colonization by A. brasilense was stimulated by naringenin and other flavonoid molecules.  相似文献

Effects of fertilizer application and fire regime on soil microbial biomass carbon and nitrogen,and nitrogen mineralization in an Australian subalpine eucalypt forest   总被引：3，自引：0，他引：3  

A. K. M. A. Hossain  R. J. Raison  P. K. Khanna 《Biology and Fertility of Soils》1995,19(2-3):246-252

The effects of a range of fertilizer applications and of repeated low-intensity prescribed fires on microbial biomass C and N, and in situ N mineralization were studied in an acid soil under subalpine Eucalyptus pauciflora forest near Canberra, Australia. Fertilizer treatments (N, P, N+P, line + P, sucrose + P), and P in particular, tended to lower biomass N. The fertilizer effects were greatest in spring and smaller in summer and late actumn. Low-intensity prescribed fire lowered biomass N at a soil depth of 0–5 cm with the effect being greater in the most frequently burnt soils. No interactions between fire treatments, season, and depth were significant. Only the lime + P and N+P treatments significantly affected soil microbial biomass C contents. The N+P treatment increased biomass C only at 0–2.5 cm in depth, but the soil depth of entire 0–10 cm had much higher (>doubled) biomass C values in the line + P treatment. Frequent (two or three times a year) burning reduced microbial boomass C, but the reverse was true in soils under forest burn at intervals of 7 years. Soil N mineralization was increased by the addition of N and P (alone or in combination), line + P, and sucrose + P to the soil. The same was true for the ratio of N mineralization to biomass N. Soil N mineralization was retarded by repeated fire treatments, especially the more frequent fire treatment where rates were only about half those measured in unburnt soils. There was no relationship between microbial biomass N (kg N ha^-1) and the field rates of soil N mineralization (kg N ha^-1 month^-1). The results suggest that although soil microbial biomass N represents a distinct pool of N, it is not a useful measure of N turnover.  相似文献   

Detection of brucella antigen in bovine fetal stomach contents by agar gel precipitation and counter-immunoelectrophoresis   总被引：1，自引：0，他引：1  

P Chand  R K Gupta  R N Khanna  J R Sadana 《Research in veterinary science》1987,43(1):132-133

Among 21 fetuses from serologically positive dams soluble brucella antigen was detected in the stomach contents in 14 instances by agar gel precipitation test and in 19 by counterimmunoelectrophoresis. Brucella abortus biotype 3 was isolated from the fetal stomach contents in 15 of these cases. None of 20 fetuses from serologically negative dams revealed brucella antigen in the stomach contents in either test.  相似文献
