Classification of grape berries according to diameter and total soluble solids to study the effect of light and temperature on methoxypyrazine, glutathione, and hydroxycinnamate evolution during ripening of Sauvignon blanc (Vitis vinifera L.).

Grape berries were classified according to diameter and total soluble solids (TSS) to study the effect of light and temperature on methoxypyrazines (MPs), glutathione (GSH), and hydroxycinnamates (HCAs) during the ripening of Sauvignon blanc. The light exposure of the fruiting zone was modified within leaf and lateral removal at the phenological stage berry of peppercorn size and no removal (control). In comparison to the control, the concentration of 3-isobutyl-2-methoxypyrazine (IBMP) was below the limit of detection in leaf removal 2 weeks before harvest.

Pesticide residues in grapes from vineyards included in integrated pest management in Slovenia.

Although the list of pesticides used in integrated pest management (IPM) in grape growing and their annual application rates are limited, we are still confronted with the problem of pesticide residues in grapes. This paper presents the results of pesticide monitoring of 47 samples of wine grapes (Vitis vinifera L.) from the 2006 vintage from vineyards included in IPM.

Monitoring of pesticide residues in apples, lettuce and potato of the Slovene origin, 2001-04.

Apples, lettuce and potatoes (404 samples) produced in the Republic of Slovenia were analysed for pesticide residues at the Agricultural Institute of Slovenia, Ljubljana, in 2001-04. Sampling from eight agricultural production areas was performed at market producers at the harvesting of products or in storehouses after the pre-harvest interval of plant protection products used. Samples exceeding the maximum residue levels were the following: three apple samples (2.

Anticarcinoembryonic antigen immunoscintigraphy with a 99mTc-Fab' fragment (Immu 4) in primary and recurrent colorectal cancer. A prospective study.

Forty-seven patients were submitted to 68 radioimmunoscintigraphic investigations for primary or recurrent colorectal cancer. Immunoscintigraphy with Immu-4 correctly detected 28 primary colorectal cancers of 29 and 12 of 12 recurrent colorectal cancers. Overall accuracy was 93.

First experiences with the heparin-induced extracorporeal low-density lipoprotein precipitation in the treatment of critical limb ischaemia: a new therapeutical approach?

The heparin-induced extracorporeal low-density lipoprotein (LDL) precipitation (HELP) system is based on the fact that besides lipoproteins even fibrinogen, which seems to be a very important factor in pathogenesis of peripheral arterial disease, is precipitated by high-dose heparin at acid pH values. The elimination of excess fibrinogen and lipoproteins, in particular LDL, leads to a markedly improved microcirculation. The restoration of the latter obviously enabled us to perform limb-saving surgical procedures instead of mutilating amputations.
