    Laparoscopic cholecystjejunostomy as palliation for obstructive jaundice in inoperable carcinoma of pancreas (1992)

    Notes: Summary Malignant obstructive jaundice can be palliated by either surgical bypass, which has the advantage of long-term patency, or by stent placement, which has the advantage of initial lower morbidity and mortality. We describe a technique, laparoscopic cholecystjejunostomy, which has the advantage of both. We predict that laparoscopic surgery, which has already had a major impact on biliary stone surgery, will also have a major impact on interventional endoscopic retrograde cholangiopancreatography.

    Genetic analysis of salt tolerance during germination in Lycopersicon (1991)
    Springer
    Theoretical and applied genetics 81 (1991), S. 321-326 
    Details
    ISSN: 1432-2242
    Keywords: Lycopersicon esculentum ; Salt tolerance ; Seed germination ; Maternal effects ; Tomato improvement ; Gene action
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary The salt-tolerant cultivated tomato (Lycopersicon esculentum) accession, ‘PI174263’, and a sensitive cv, ‘UCT5’, were crossed to develop reciprocal F1, F2 and BC1 populations for genetic analysis of salt tolerance in tomatoes during seed germination. Variation was partitioned into embryo, endosperm and maternal (testa and cytoplasmic) components. Generation means analysis indicated that there were no significant embryo (additive, dominance or epistatic) effects on germination performance under salt stress. Highly significant endosperm additive and testa dominance effects were detected. The proportion of the total variance explained by the model containing these two components was R2=98.2%. Variance component analysis indicated a large genetic variance with additive gene action as the predominant component. Furhter inspection indicated that this variance was attributable to endosperm additive effects on germinability under salt stress. Narrow-sense heritability was estimated as moderately high. Implications for breeding procedures are discussed.

    Laparoscopic cholecystectomy for complicated gallstone disease (1992)
    Springer
    Surgical endoscopy and other interventional techniques 6 (1992), S. 179-182 
    Details
    ISSN: 1432-2218
    Keywords: Cholelithiasis ; Choledocholithiasis ; Cholecystectomy ; Laparoscopy ; ERCP ; Endoscopic sphincterotomy

    Notes: Summary After performing selectively 25 laparoscopic cholecystectomies (LC) to determine the place of LC in the management of complicated gallstones, all patients presenting with gallstones were evaluated by the authors for LC. Eighty-six consecutive patients were evaluated and 84 were studied. Follow-up in every case exceeded 6 months. In three of 10 patients with acute cholecystitis, LC was not possible; each had a history longer than 48 h and all had gangrene of the gallbladder. In four patients with empyema, LC was successful, but operative cholangiography failed. Operative cholangiography was successful in 76 of the remaining 77. Of eight patients suspected of having stones in the CBD, cholangiography excluded stones in six and confirmed them in two. Cholangiography identified three other patients with totally unsuspected CBD stones. Of the five patients with CBD stones, four had them flushed to the duodenum at LC following transcystic balloon dilatation of the papilla and one had a post-op. ERCP. Of four patients with acute pancreatitis, three had LC in the same admission. LC was possible in all three patients with morbid obesity. We conclude that with experience, LC is possible for complicated gallstones. In acute cholecystitis, the probability of success is higher with earlier operative intervention. Operative cholangiography is essential. It not only identifies unsuspected CBD stones but also allows LC without ERCP in those with suspected CBD stones and with modification it allows treatment of those stones.

    Generation means analysis of right-censored response-time traits: Low temperature seed germination in tomato (1990)
    Springer
    Euphytica 48 (1990), S. 239-244 
    Details
    ISSN: 1573-5060
    Keywords: Lycopersicon esculentum ; tomato ; cold tolerance ; seed germination ; genetic analysis ; missing data ; response-time data

    Notes: Summary In studies to determine the inheritance of response-time traits, such as time to seed germination, some viable individuals may fail to respond during an experiment. If these right-censored observations are ignored, sample means and variances will be underestimated. This is illustrated using data from time to seed germination at 9°C for Lycopersicon esculentum (Mill.) fast germinating PI 120256, slow-germinating T3 and their reciprocal F1, F2 and backcross progeny. This paper presents methods to detect and to accommodate right-censored data in generation means analysis. Genetic interpretations derived from corrected and uncorrected estimates of generation means and variances are compared. Correction for right-censoring increased estimates of environmental and phenotypic variances, and decreased heritability estimates.
