    Notes: Abstract Measurements of the dielectric susceptibility of a series of lanthanum ethyl sulfate/cerium ethyl sulfate crystals (5–100 at % Ce) have been made over the temperature range 0.05–20 K. The results confirm the Jahn-Teller distortion in pure cerium ethyl sulfate, demonstrate a distortion for up to 25% La in the mixed crystals, and confirm the inversion of the zero-temperature crystal field splitting at about 40% La. The dipole moment of the cerium ion was found to be (5.2±0.4)×10−31 and (6.7±0.5)×10−31 C m for the applied electric field perpendicular and parallel to thec axis, respectively.

    Effects of salmon calcitonin and combination drug therapy on rat adjuvant arthritis (1974)

    Topics: Medicine
    Notes: Abstract The effect of chronic administration of salmon calcitonin (SCT) to rats with adjuvant arthritis was studied. Compared to arthritic controls, 10 units/kg day in a divided dose of SCT given s.c. resulted in a significant inhibition of paw edema and a reduction in the marked deterioration of the bones of the hind limbs, particularly those of the tarsus, as visualized by x-ray. In addition, a pronounced increase in bone density in the proximal metaphyseal area of the tibia was consistently observed in calcitonin treated animals. Animals treated with SCT also showed improved clinical symptoms including increased mobility and decreased sensitivity to handling compared to arthritic controls. Combinations of SCT with each of several antiinflammatory agents, including phenylbutazone, hydrocortisone acetate and ACTH, produced greater degrees of inhibition of paw edema and ankle bone deterioration than did the individual agents alone. In addition, administration of calcium chloride solution, per os, alone and in combination with SCT partially inhibited the disease.

    Notes: Summary Winter wheat cultivars released in the Netherlands before 1930 carried durable resistance to yellow rust. Cultivars released in the period between 1930 and 1950 often were durably resistant while recent cultivars infrequently showed durable resistance. This durable resistance was not difficult to transfer to new cultivars. Twenty nine older cultivars with durable resistance and eight recent non-durably resistant cultivars were tested in the seedling stage and in the adult plant stage against 12 West-European yellow rust races and against some non-European races in the seedling stage only. The adult plant tests were carried out in ‘race nursery’ tests in the Flevopolder. Per race nursery all 37 cultivars, planted in hills of about 20 plants on both sides of the highly susceptible cv. Michigan Amber, were exposed to one race. The infection type of each cultivar-race combination was scored on 0 to 9 scale once in the seedling stage and twice in the adult plant stage. In the race nurseries the percentage leaf area affected was evaluated three times to be used to calculate the area under the disease progress curve (AUDPC). This AUDPC multiplied with the mean infection type in the field gave the susceptibility index (SI). The infection types were classified into resistant (R), intermediate (I) or susceptible (S) when the infection types were 0 to 3, 4 to 6 or 7 to 9, respectively. Four categories of resistance were discerned on the basis of the three infection type scores: 1) RRR, overall resistance; complete or near-complete resistant at all stages. 2) SRR, adult plant resistance, complete- or near-complete resistant at the adult plant stage only. 3) SRS and SSR, temperature sensitive resistance, the resistance changed from the one evaluation data to the other. 4) SSS and an SI lower than that of Michigan Amber, partial resistance. The frequencies of overall, adult plant and temperature sensitive resistance were 1.4, 52 and 54% in the older cultivars and 40, 62 and 22% in the recent ones, respectively. Among the older cultivars all had a fair to high level of partial resistance, the SI being on average only 20% of that of Michigan Amber, while most cultivars also seemed to carry temperature sensitive resistance. The partial resistance of the recent cultivars was of a much lower level with a mean SI compared to that of Michigan Amber of 61%. Partial resistance was highly correlated (r = −0.94) with the mean resistance scores from the Dutch Recommended Cultivars Lists. It was concluded that partial resistance and temperature sensitive resistance were the major components of the durable resistance in the older cultivars.

    Notes: Summary Three lines derived from the old ‘dirty’ Dutch land variety Gelderse Ris were resistant against race 66(70)EO(16) of yellow rust. It was found that this resistance was conditioned by one recessive gene provisionally coded yrGR.

    Evolution of virulence patterns in yellow rust races and its implications for Ereeding for resistance in wheat in Kenya (1994)

    Notes: Summary Virulence patterns of yellow rust isolates collected in Kenya between 1986–1989 were compared with earlier results. The number of virulence factors per race and the range in virulence factors both increased considerably. Before 1976 races carried on average 4.5 to 5.0 virulence factors, whereas the races after 1986 had a mean of 6.5 virulence factors. The range in the number of virulence factors increased from some seven to eight in the first period to 12 in the second out of the 17 evaluated. In the period 1986–1989 another three virulence factors (2, 9 and A) were assessed. All three occurred at a high frequency. Virulence neutralizing the resistance genes Yr2, Yr2+, Yr6, Yr6+, Yr7, Yr7+, Yr8, Yr9, Yr9+ and those in the cultivars Anza (A), Strubes Dickkopf (SD) and Suwon92/Omar (SU) occurred at a high frequency, while virulence for Yr3V, Yr4+, Yr5, CV and SP (resistance in Carstens V and Spaldings Prolific resp.) were not found. The remaining three virulence factors for Yr1, 10 and 3N were rare. In the past ten years the resistance of most released cultivars became ineffective in less than six years. They were shown to carry race-specific major resistance genes such as Yr7+, Yr9+, SD and A. However, in the field, the resistance of the cultivars was not completely neutralized. A residual resistance, ranging from moderate to fairly high, was observed in all cultivars in which the major gene resistances were neutralized by corresponding virulence genes. Other wheat cultivars such as Africa Mayo, Kenya Kudu, Enkoy, Kenya Leopard, Bounty, Frontatch, Bonny and Kenya Plume appeared to keep their resistance over a condiserable period of time. They are considered to be durably resistant to the Kenyan yellow rust populations. This form of resistance, together with the residual resistance, can be recommended for use in breeding programmes.

    A valuable source of yellow rust resistance in Israeli populations of wild emmer,Triticum dicoccoides Koern. (1970)

    Notes: Summary An extensive collection of wild emmer was screened for yellow rust resistance in a joint project by research institutes in Israel and The Netherlands. In inoculation experiments performed both in seedling stage and at maturity, the wild emmer accessions displayed a diversity of responses to yellow rust infection, ranging from immunity to complete susceptibility. SelectionTriticum dicoccoides var.aaronsohni G-25 was most promising proving highly resistant to all 21 races and field races used. Selection G-7, which was also very resistant in the trials, differed slightly from G-25 in infection types produced on inoculation with one of the isolates; this may be an indication that the genetic factors controlling resistance in these two selections are not identical. It is concluded that the diversified populations of wild emmer indigenous to Israel possess genes which confer high resistance to a very wide spectrum of yellow rust races, including all common races in Western Europe and the Middle East. As resistance factors can be transferred easily fromT. dicoccoides to durum and common wheat, this source may be utilized in producing varieties of cultivated wheat with improved yellow rust resistance.

    Notes: Samenvatting In toetsingen van F1-en F2-kiemplanten van enige tarwekruisingen is gebleken dat het infectietype op het tweede blad tegenovergesteld kan zijn aan dat van het eerste. Dit verschijnsel zou verband kunnen houden met de invloed van het endosperm op de fysiologie van het eerste blad, terwijl de reactie van het tweede, blad bepaald wordt door het genotype van het embryo. De graduele verschillen in infectietypen op het eerste blad van F2-kiemplanten, een verschijnsel dat ook door Macer (1966) is gevonden, zouden het gevolg kunnen zijn van een gen-dosis effect in het endosperm.
