We compared photosynthesis and growth of Zea mays L (corn) and four weed species, Setaria viridis (L) Beauv (green foxtail), Echinochloa crus-galli (L) Beauv (barnyardgrass), Abutilon theophrasti Medic (velvetleaf), and Amaranthus retroflexus L (redroot pigweed), following foliar applications with atrazine, mesotrione, or a combination of atrazine and mesotrione in two greenhouse experiments. P...

Four new species of terrestrial isopods from Sardinia are described: Alpioniscus thanit sp. nov. (Trichoniscidae), Halophiloscia cristagalli sp. nov. (Halophilosciidae), Alloschizidium maymon sp. nov. and Alloschizidium magrinii sp. nov. (Armadillidiidae). Alpioniscus thanit and Alloschizidium magrinii were collected in endogean environments, Halophiloscia cristagalli on granitic beaches of sma...

BACKGROUND AND PURPOSE The crista galli is part of the ethmoid bone and, as such, it could be expected that aeration of the crista would come from ethmoid cells. After observing crista pneumatization from the frontal sinuses in several cases, we undertook this study to establish how often crista galli pneumatization came from the frontal sinuses rather than from the ethmoid complex. MATERIALS...

The effect of dietary manganese from two different sources on chicks (uninfected and infected with Ascaridia galli) was studied. Chick diet was supplemented with 0.9 g Mn2+ kg-1 food either in the form of MnSO4.H2O or 2Gly. MnCl2.2H2O for 20 days. Chicks were divided into six groups: group 0, control; group 1, control + MnSO4.H2O; group 2, control + 2Gly.MnCl2.2H2O; group 3, infected with A. ga...

INTRODUCTION  The crista galli is part of the ethmoid bone and thus may suffer from the process of pneumatization. Pneumatization occurs in between 3% and 14% of patients, resulting from air cells in the frontal or ethmoid sinuses. AIM  To describe 3 cases of crista galli pneumatization in which the patients developed infection and were treated surgically by endoscopic techniques. METHOD  W...

Two new Erythrinan alkaloids, cristanines A and B (1, 2), were isolated from the bark of Erythrina crista-galli L. together with nine known Erythrinan alkaloids (3-5, 7-12) and an indole alkaloid (13). The structures of the compounds, cristanines A (1) and B (2), were elucidated by spectroscopic methods. Three of the twelve compounds isolated showed significant inhibitory activity on lipopolysa...

Three experiments were carried out to examine the consequences of concurrent infections with Ascaridia galli and Escherichia coli in chickens raised for table egg production. Characteristic pathological lesions including airsacculitis, peritonitis and/or polyserositis were seen in all groups infected with E. coli. Furthermore, a trend for increased mortality rates was observed in groups infecte...
