    Effects of a hexachlorinated biphenyl on lymphoid organs and resorption of foetuses in pregnant mice (1981)
    Springer
    Archives of environmental contamination and toxicology 10 (1981), S. 281-288

    Notes: Abstract Syngeneically and allogeneically mated CBA mice were daily given orally either pure peanut oil or peanut oil containing 0.5 mg 2,2′,4,4′,5,5′-hexachlorobiphenyl (HCB) beginning at the day of implantation. The mice were dissected on day 12 and 18 of gestation when the weight of thymus, spleen, and liver were recorded. The spontaneous mitotic activity of spleen cells was evaluatedin vitro, and the number of resorbed foetuses was recorded. Neither spleen weight nor thymus weight was altered, but the liver weight was significantly increased by HCB treatment. The spontaneous mitotic activity of spleen cells did not differ significantly between HCB treated and control mice. The frequency of resorbed foetuses was not increased by HCB treatment either in syngeneically or allogeneically mated mice, but it was observed that mice fed HCB were less sensitive to environmental disturbance than control mice.

    Predicting field performance using seedling quality assessment (1997)
    Springer
    New forests 13 (1997), S. 227-252 
    Details
    ISSN: 1573-5095
    Keywords: correlation to field growth ; measurement techniques ; seedling attributes ; seedling quality
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract Seedling quality is defined as “fitness for purpose”. Attributes for assessing seedling quality are grouped in “material attributes” that can be rapidly assessed by any number of direct or indirect methods, and “performance attributes” that are assessed by subjecting whole seedlings to certain environmental regimes and evaluating their growth response. “Material attributes” comprising morphology, bud dormancy, water relations and nutrition and “performance attributes” comprising frost hardiness, vigour and root growth potential are discussed with regard to relevance for predicting field performance. Measurement techniques and relevance in assessing seedling quality are presented for different physiological attributes: electrolyte leakage, enzymatic activity, water potential, water conductance, mineral nutrition, food reserves, mitotic index, gas exchange, chlorophyll content, plant growth regulators, stress-induced volatile emission, and nuclear magnetic resonance. Methods with future potential in improving the prediction of field performance are identified and discussed. The methods presented in this respect are chlorophyll fluorescence, infrared thermography, machine vision systems, integrated approaches and ecophysiological evaluations.

    Breast conserving surgery for invasive breast cancer: Risk factors for ipsilateral breast tumor recurrences (1997)

    Notes: Abstract To identify risk factors associated with an increasedrisk for ipsilateral breast tumor recurrence following breast-conservingsurgery, a cohort of 759 women with T1–T2tumors were studied. The majority of the patients(88%) had received postoperative radiation therapy to thebreast. Median follow-up time was 10 (range: 6–17)years. There was a 1–1.5% yearly increase inipsilateral breast tumor recurrences. For women 〈 50ys the cumulative recurrence rate at 10 yearswas 18% and for women ≥ 50 ys,9%. Node positive women had a cumulative breastrecurrence rate of 25% versus 10% for nodenegative women. Ten years postoperatively, irradiated patients hada cumulative recurrence rate of 11% versus 26%when no irradiation was given. The beneficial effectof radiotherapy was substantial during the first fourpostoperative years. The relative risk for an ipsilateralbreast tumor recurrence during this period was 4.5times higher than for non irradiated patients. However,the protective effect of radiotherapy decreased with time.After ten years the relative risk of ipsilateralbreast tumor recurrence was the same among irradiatedand non-irradiated patients although the number of eventsduring this period was low.Univariate analysis showed that seven factors were significantlyassociated with an increased risk of ipsilateral breasttumor recurrence, namely age 〈 50 ys, increasingtumor size, uncertain microscopic margins, axillary lymph nodemetastases, no postoperative tamoxifen treatment, premenopausal status, andno postoperative radiotherapy. Three factors remained independently significantafter multivariate analysis: age 〈 50 ys,no postoperative radiation therapy, and positive lymph nodes.In conclusion, radiotherapy reduced the breast recurrence rate,but the effect decreased with time. Node-negative women≥ 50 were a low risk-group for ipsilateralbreast tumor recurrence, with a cumulative risk at10 years of 9% without radiation therapy and5% with breast irradiation.
