    Notes: Samples of maize seed were obtained from countries in Central America, Africa and Asia and assessed for fungal infection. Fusarium spp. were the largest single group of fungi present, and from these Fusarium moniliforme was the species most frequently isolated. Other fungi, including Stenocarpella (Diplodia) maydis, S. macrospora and Acremonium strictum, were also present in significant numbers. Isolates of F. moniliforme were characterized for mating populations, using RAPDs, and a number of isolates, taken at random from those assigned to specific mating groups, were also confirmed by crossing. Isolates were also characterized for fusaric acid production and significant differences in fusaric acid production were detected between isolates from different countries and regions within countries. A detailed analysis of isolates from one country, Kenya, was undertaken. The importance of the pathogens is discussed in relation to human, animal and seed health and quarantine regulations, and plant breeding objectives.

    Notes: Background: As many as 50% of patients with reflux symptoms have no endoscopic evidence of oesophagitis. This multicentre study was designed to assess symptom relief after omeprazole 20 mg once daily in patients with symptoms typical of gastro-oesophageal reflux disease but without endoscopic evidence of oesophagitis. Methods: Patients (n=209) were randomized in a double-blind study to receive either omeprazole 20 mg once daily (n=98) or placebo (n=111) for 4 weeks. Symptoms were assessed at clinic visits and using daily diary cards, with patient-completed questionnaires providing additional data on symptoms and on psychological disturbance. Results: On completion, symptom relief favoured omeprazole: 57% of patients on omeprazole were free of heartburn (vs. 19% on placebo), 75% were free of regurgitation (47%) and 43% were completely asymptomatic (14%), each with P〈0.0001. Fewer patients in the omeprazole group required alginate/antacid relief medication (P〈0.05). Symptom relief (time to first heartburn-free day) was more rapid with omeprazole (2 vs. 5 days on placebo; P〈0.01). A greater reduction in anxiety occurred in the omeprazole group (P〈0.05). Conclusion: Omeprazole 20 mg once daily is effective in providing relief of the symptoms typical of gastro-oesophageal reflux disease in patients with essentially normal oesophageal mucosa.

    Notes: The management of primary sclerosing cholangitis (PSC) is hindered by incomplete understanding of the pathogenesis of the disease and the lack of good prognostic models. Few large randomized controlled trials of drug therapy have been published. Best practice in the management of PSC is currently based therefore on careful interpretation of the available evidence, close observation of individual patients and clinical experience of the disease. Drug therapy is useful for alleviating symptoms. Ursodeoxycholic acid may slow progression of the disease and reduce the frequency of complications. Consensus is emerging on the issues of screening for the malignant complications of PSC and the indications for liver transplantation are becoming broader and encompassing the earliest stages of cholangiocarcinoma. In view of the rarity of the disease in the general population, large international collaborations to study PSC are necessary to provide clearer answers in areas of uncertainty, and these are now beginning to emerge.

    Notes: Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease characterized by a progressive obliterating fibrosis of the intrahepatic and extrahepatic bile ducts. The pathogenesis of PSC is poorly understood but it is thought to be an immune-mediated disease. The optimal therapy which successfully improves symptoms, delays progression towards liver failure and transplantation and prevents the onset of cholangiocarcinoma remains elusive. Although current treatments are used to manage cholestasis and its consequences and some of the more general complications of the disease, none of the current therapeutic agents have been shown to retard and reverse the rate of disease progression. The role of cupruretics, corticosteroids, methotrexate, anti-fibrogenic agents and ursodeoxycholic acid in the treatment of PSC is reviewed. Orthotopic liver transplantation remains the only therapeutic option for advanced PSC but the timing of transplantation remains controversial and the possibility of recurrence of the disease in the graft is increasingly recognised. It is likely that greater insight into the pathogenetic mechanisms involved in PSC will allow therapy to be targetted more specifically at the biliary epithelium.

    Notes: [Auszug] Gamma-ray bursts (GRBs) and their afterglows are the most brilliant transient events in the Universe. Both the bursts themselves and their afterglows have been predicted to be visible out to redshifts of z ≈ 20, and therefore to be powerful probes of the early Universe. The burst GRB 000131, ...

    Notes: [Auszug] Gamma-ray bursts (GRBs) divide into two classes: ‘long’, which typically have initial durations of T90 〉 2 s, and ‘short’, with durations of T90 〈 2 s (where T90 is the time to detect 90% of the observed fluence). Long ...

    Description / Table of Contents: Zusammenfassung Die Nahrungsmenge, die von einer Larve der Wanderheuschrecke, Locusta migratoria L., im fünften Entwicklungsstadium bei einer einzigen Mahlzeit verzehrt wird, wurde ermittelt, indem ihr Darm und Darminhalt sofort nach dem Fressen gewogen wurden. In der Mitte des Entwicklungsstadiums wurden größere Mengen verzehrt, Weibchen fraßen mehr als Männchen, jedoch sind die weiblichen Larven ja auch größer. Die Menge der aufgenommenen Nahrung vergrößerte sich mit der Dauer künstlichen Futterentzuges. Sie erreichte ihren Höhepunkt nach sechs Stunden, nach welcher Zeit der Vorderdarm absolut leer war. Die verzehrten Mengen waren je nach der Art der Nahrung unterschiedlich. Auch stellten die Insekten sich so ein, daß sie von einer bestimmten Nahrung mehr zu sich nahmen, wenn sie daran aufgezogen worden waren. Nach längeren Zeitspannen der Isolierung hatten sie die Tendenz, weniger zu fressen. Temperatur und Feuchtigkeit hatten keinen Einfluß auf die Mengen, die verzehrt wurden, außer bei 40°, bei welcher Temperatur sich das gesamte Verhalten zum Fressen ändert.
    Notes: Abstract Meal size in fifth-instar nymphs of Locusta migratoria L. has been investigated by weighing the gut and its contents immediately after feeding. Larger meals are taken in mid-instar, while females eat more in one meal than males under the same conditions. Bigger meals are also eaten after longer periods of food deprivation, but after deprivation for two hours or less, corresponding with the normal interfeed length, meals are smaller than would be expected from the potential maximum foregut volume. The maximum volume attained varies with the type of food available to the insects and is influenced by previous conditioning. Temperature and humidity do not affect meal size except at 40°, at which temperature the usual pattern of feeding is completely altered.

    Notes: Abstract. The neutron deficient 199At nucleus has been studied in the 175Lu+28Si reaction at Eb= 141 MeV. In order to select events of interest in the presence of the very strong background caused by fission, γ-rays have been detected in coincidence with recoiling evaporation residues. The excited states of 199At observed for the first time may indicate that this nucleus is deformed.
