1. Canopy management effects on ‘Syrah’ grapevines under tropical semi-arid conditions
ABSTRACT The aim of this study was to evaluate the effects of shoot topping and leaf removal practices on vegetative vigor, yield and physicochemical characteristics of the 'Syrah' grape in the semi-arid tropical climate conditions of the São Francisco River Valley in the northeast of Brazil. The experiment was conducted over five growing cycles from 2010 t

2. Manejo do dossel vegetativo da videira e seu efeito na composição do vinho Merlot.
O objetivo deste trabalho foi avaliar o efeito de modalidades de poda verde da videira (Vitis vinifera L.) na composição do vinho Merlot. Um experimento foi conduzido de 1993/1994 a 1996/1997, em Bento Gonçalves, RS, com uma testemunha e 11 modalidades de poda verde em vinhedo conduzido em latada. A análise de componentes principais mostrou que o efeit

3. Topping off: A mechanism of first-male sperm precedence in a vertebrate
Competition among the sperm of rival males is an important evolutionary phenomenon in many organisms. Yet, despite extensive research on sperm competition in some vertebrate taxa, very little progress has been made on this topic in amphibians. Urodele amphibians (newts and salamanders) are of particular interest to theories of sperm competition because most

4. Traumatic wound dehiscence following penetrating keratoplasty.
Four young male patients with keratoconus had traumatic dehiscence of the surgical wound after penetrating keratoplasty. Two were rendered aphakic by the trauma, and in one patient the lens was dislocated posteriorly. In each case the dehiscence was repaired by resuturing the original corneal graft. Despite marked corneal oedema in the immediate postoperativ

5. The illegality of private health care in Canada
WE ADDRESSED THE QUESTION OF WHETHER PRIVATE HEALTH CARE IS ILLEGAL in Canada by surveying the health insurance legislation of all 10 provinces. Our survey revealed multiple layers of regulation that seem to have as their primary objective preventing the public sector from subsidizing the private sector, as opposed to rendering privately funded practice ille

6. Castor bean allergy in the upholstery department of a furniture factory.
In this study, undertaken to identify the cause of allergy in several upholstery workers in a furniture factory, the workers were handling several different materials, including glue, silicone spray, upholstery fabrics, and felt. Radio-allergo-sorbent test (RAST) assays showed that sera from sensitised workers contained specific IgE towards the felt; however

7. Stability of amoxicillin-clavulanate in BACTEC medium determined by high-performance liquid chromatography and bioassay.
The stabilities of amoxicillin (16 micrograms/ml) and clavulanate (8 micrograms/ml), alone and in combination in BACTEC medium (Middlebrook 7H12B medium), were determined by high-performance liquid chromatography (HPLC) and bioassay. By HPLC, the half-life of amoxicillin (trihydrate and sodium) in combination with clavulanate in nonradiolabelled 7H12B medium

8. Clinical and immunological reactions to Aspergillus niger among workers at a biotechnology plant.
The workforce at a biotechnology plant producing citric acid by fermentation of molasses with a strain of Aspergillus niger was studied. A combination of a respiratory questionnaire and clinical assessment identified 18 subjects (4.9% of the workforce) with work related bronchospasm. In nine of these evidence of sensitisation to A niger was obtained by skin

9. Promoter trap markers differentiate structural and positional components of polar development in Arabidopsis.
To investigate mechanisms involved in establishing polar organization in Arabidopsis embryos and seedlings, we used promoter trapping to identify molecular markers (beta-glucuronidase fusion genes) expressed in spatially restricted patterns along the apical-basal axis. Three markers were identified that are expressed, respectively, in the embryonic and seedl

10. N4-Hexanoylspermidine, a New Polyamine-Related Compound That Accumulates during Ovary and Petal Senescence in Pea.
A previously unknown polyamine conjugate that accumulates in senescing ovaries of pea (Pisum sativum L.) was shown by mass spectrometry, nuclear magnetic resonance, and chemical synthesis to be N4-hexanoylspermidine (hexanoyl-spd) This structure was indicated by analysis of the dansylated polyamine using fast atom bombardment mass spectrometry, following pur

11. Mismatch Repair Protein Deficiency Compromises Cisplatin-induced Apoptotic Signaling*S⃞
Mismatch repair (MMR) proteins participate in cytotoxicity induced by certain DNA damage-inducing agents, including cisplatin (cis-diamminedichloroplatinum(II), CDDP), a cancer chemotherapeutic drug utilized clinically to treat a variety of malignancies. MMR proteins have been demonstrated to bind to CDDP-DNA adducts and initiate MMR protein-dependent c

12. Metal Complexation in Xylem Fluid 1: I. CHEMICAL COMPOSITION OF TOMATO AND SOYBEAN STEM EXUDATE
Xylem fluid was analyzed for numerous solutes to characterize chemically the sap as a medium for forming and transporting metal complexes. The stem exudate was collected hourly for 8 hours from topped 31-day-old soybean (Glycine max L. Merr.) and 46-day-old tomato (Lycopersicon esculentum Mill.) plants grown in normal (0.5 micromolar) and Za-phytotoxic nutri
