Abstract:
Isolated Necturus proximal tubules were split to expose the apical membrane surface for patch clamping. When both pipette and bath solutions contained only Ca, N-methyl-D-glucamine, and methanesulfonate, inwardly directed Ca currents were observed through a stretch-activated (SA) cation channel with conductance of 18 +/- 1 pS (n = 19). The SA cation channel exhibited little discrimination among Na, K, and Ca but was at least nine times more selective for cations than anions. The channel was not significantly gated by either membrane potential or cytosolic Ca. However, application of 15 cmH2O suction to patch pipette significantly increased the mean number of open channels by a factor of 6.5, from 0.04 +/- 0.02 to 0.26 +/- 0.08 (n = 11). Ca currents through the SA cation channel were reversibly blocked by 10 microM gadolinium, which was applied to outside surface of excised patches. This is similar to gadolinium block of stretch-activated channels in Xenopus oocytes (X.-C. Yang and F. Sachs. Science Wash. DC 243: 1068-1071, 1989). A Ca-dependent, maxi-K channel (92 +/- 9 pS, n = 5) was also found at the apical membrane of the same proximal tubules. In some cases this maxi-K channel appeared to be indirectly activated by pipette suction, raising the possibility that Ca influx through the SA cation channel may regulate K efflux via the maxi-K channel. Such a process could mediate cell volume regulation and maintain electrolyte homeostasis during normal variations in Na-substrate cotransport.

Abstract:
Resumo O objetivo deste estudo foi avaliar os efeitos da fertirrigação com água residuária de origem urbana bruta, aplicada via gotejamento e sem adubação química, sobre a nutrição do café arábica (Coffea arabica); comparado com a irrigação com água doce mais adubação convencional, o experimento foi conduzido na Unidade Piloto de Tratamento de Água Residuária e Agricultura Irrigada, no campus da UFV, durante 18 meses. Cinco foram os tratamentos fertirrigados (MR’s) com cinco lâminas de água residuária (406, 515, 798, 924 e 1071 mm) e um irrigado com água doce mais adubação e calagem (MC). Avaliaram-se os teores de macronutrientes (N, P, K, Ca, Mg e S) nas folhas do cafeeiro, ao longo do tempo, em seis análises trimestrais. Os resultados demonstraram que: O MR apresentou maior teor de Mg que o MC, durante todo o período avaliado e de Ca e P durante os primeiros 12 meses; os teores de N e S não diferiram entre os tratamentos, e o teor de K no MC foi sempre superior ao do MR.

Abstract:
1071 Background: N0234 is a phase II trial of gemcitabine at 1000 mg/m2 days 1 and 8 of a 21 day cycle and erlotinib at 150 mg daily in patients with previous therapy with either an anthracycline or a taxane for MBC. A partial response (PR) rate of 17% has been reported (ASCO 2005). Recent information suggests that over-expression of the EGFR pathway is frequent in patients with TNeg MBC. Methods: Tissue and serum were obtained for translational studies of ER, PR, HER2, and proteins related to EGFR pathway on tissue using immunohistochemistry; CK19, mammoglobin, and TTK on circulating tumor cells (CTCs). Markers were evaluated centrally, blinded to patient outcome. Complete data were available in 57 of 59 eligible patients; 20/57 patients (pts) were TNeg. Results: A PR rate of 25% and clinical benefit rate (PR + stable disease > 6 months)of 25% was observed in TNeg pts as compared to a PR rate of 14% (p = 0.30) and clinical benefit rate 22% (p= 0.75) for non-TNeg pts. Median progression free survival 72 days vs 98 days (p=0.13) and overall survival 227 days vs 738 days (p<0.001) were shorter for TNeg pts. Translational results for the EGFR pathway proteins and CTC analysis is forthcoming. Conclusions: The combination of gemcitabine and erlotinib appears to be as active in the non-TNeg and TNeg subset of patients on this trial. TNeg patients had an inferior clinical result, confirming the poor outcome seen in these patients. Data for the remaining biomarkers potentially predictive of activity will be presented.

Abstract:
The present study examines the prevalence and characteristics of vegetarians in the Taiwanese elderly. We analysed data from the Elderly Nutrition and Health Survey in Taiwan (1999–2000), which used a multi-staged, stratified, clustered probability sampling design. Community-dwelling elderly (n 1071), aged 65 years and older, were included. Sociodemographic, anthropometric, lifestyle and metabolic variables, and eating habits were obtained through household interviews and health examinations. Nutrient intake was assessed using a 24 h dietary recall. Multivariable logistic regression analysis was performed to examine factors significantly and independently associated with vegetarian status and to estimate the OR of the hypertension and the metabolic syndrome (MS) for vegetarians compared with omnivores. About 25 % of the Taiwanese elderly persons were vegetarians. Systolic pressure (OR 1·01, 95 % CI 1, 1·02, P = 0·038), female sex (OR 5·02, 95 % CI 3·11, 8·1, P < 0·001), smoking status (P = 0·034; current smoker (OR 0·45, 95 % CI 0·24, 0·85, P = 0·014)) and regular exercise (OR 1·87, 95 % CI 1·37, 2·56, P < 0·001) were independently associated with vegetarian status among Taiwanese elderly persons. Vegetarians consumed significantly lower daily total energy (P < 0·001), lower cholesterol (P = 0·002), a higher percentage of fat as PUFA (P = 0·022), higher Ca (P < 0·001) and higher crude fibres (P = 0·041) compared with omnivores. Between the two vegetarian diets, ovo- or lacto-vegetarian diets contained more beneficial micronutrients, such as K, Ca and Mg, and higher crude fibres than vegan diets (all P < 0·05). The likelihood of having hypertension and the MS was not significantly different between vegetarians and omnivores as examined by sex- or multivariate-adjusted logistic regression.

Abstract:
The red list of the International Union for the Conservation of Nature and Natural Resources (IUCN) reported Castanopsis argentea as an endangered species. Studies about autecology on its natural habitat become important to perform species conservation. This study aimed to analyze the population structure, distribution pattern, and environmental factors that influence the presence of C. argentea in the Telaga Warna Nature Reserve. Data was collected in September 2020 by making 21 plots with a single plot. The purposive sampling method was used based on C. argentea representatives to determine plot location. Measurement of environmental factors, including soil sampling was carried out on each plot. Population structure was analyzed based on plant density, and Morisita index determined the distribution pattern. Environmental data were analyzed using PCA with Minitab 19 programs. Our field observation showed that C. argentea seedling has the highest density (1071 ind/ha) and decreased in the mature phase. C. argentea was found to have a clumped distribution pattern with an Id value of 1.03. PCA analysis showed differences in environmental factors that were thought to influence the presence of C. argentea individuals in four growth phases. The highest population structure of C. argentea was found in the growth phase of seedlings and saplings at an altitude of 1400 m asl. The spread population distribution of C. argentea was clumped. The influences of environmental variables on the existence of C. argentea were Mg, Ca, CEC, pH, and soil moisture.

Abstract:
The alpha 6 beta 1 integrin is expressed on the macrophage surface in an inactive state and requires cellular activation with PMA or cytokines to function as a laminin receptor (Shaw, L. M., J. M. Messier, and A. M. Mercurio. 1990. J. Cell Biol. 110:2167-2174). In the present study, the role of the alpha 6 subunit cytoplasmic domain in alpha 6 beta 1 integrin activation was examined. The use of P388D1 cells, an alpha 6-integrin deficient macrophage cell line, facilitated this analysis because expression of either the alpha 6A or alpha 6B subunit cDNAs restores their activation responsive laminin adhesion (Shaw, L. S., M. Lotz, and A. M. Mercurio. 1993. J. Biol. Chem. 268:11401-11408). A truncated alpha 6 cDNA, alpha 6-delta CYT, was constructed in which the human cytoplasmic domain sequence was deleted after the GFFKR pentapeptide. Expression of this cDNA in P388D1 cells resulted in the surface expression of a chimeric alpha 6-delta CYT beta 1 integrin that was unable to mediate laminin adhesion or increase this adhesion in response to PMA under normal conditions, i.e., in medium that contained physiological concentrations of Ca++ and Mg++. The alpha 6A-delta CYT transfectants adhered to laminin, however, when Ca++/Mg++ was replaced with 150 microM Mn++. We also assessed the role of serine phosphorylation in the regulation of alpha 6A beta 1 integrin function by site-directed mutagenesis of the two serine residues present in the alpha 6A cytoplasmic domain because this domain is phosphorylated on serine residues in response to stimuli that activate the laminin receptor function of alpha 6 A beta 1. Point mutations were introduced in the alpha 6A cDNA that changed either serine residue #1064 (M1) or serine residue #1071 (M2) to alanine residues. In addition, a double mutant (M3) was constructed in which both serine residues were changed to alanine residues. P388D1 transfectants which expressed these serine mutations adhered to laminin in response to PMA to the same extent as cells transfected with wild-type alpha 6A cDNA. These findings provide evidence for a novel mode of integrin regulation that is distinct from that reported for other regulated integrins (O'Toole, T. E., D. Mandelman, J. Forsyth, S. J. Shattil, E. F. Plow, and M. H. Ginsberg. 1991. Science (Wash. DC). 254:845-847. Hibbs, M. L., H. Xu, S. A. Stacker, and T. A. Springer. 1991. Science (Wash. DC). 251:1611-1613), and they demonstrate that serine phosphorylation of the alpha 6A cytoplasmic domain is not involved in this regulation.

Abstract:
In order to determine possible relationships between geocaulosphere soil properties and severity of common scab of potato caused by Streptomyces scabies, soils were collected from representative commercial potato fields in Canada: in Simcoe and Dufferin Counties, Ontario and across Prince Edward Island (PEI) in August 2004. Soils immediately adjacent to tubers were sampled and analyzed for select edaphic factors and for pathogen presence using polymerase chain reaction (PCR) tests with primers that amplify a region of the TxtA gene involved in regulating the biosynthesis of the thaxtomin toxin family. Individual tubers were assessed visually for scab severity. The relationships between soil chemical factors and disease severity were investigated for each region to detect the strongest relationships. Principal component analysis revealed a distinctive clustering of samples with respect to disease severity in PEI but not in Ontario soils. Total and percent saturation of K (%K) were the only factors found associated with high disease severity in soils from both provinces. In PEI soils, pH, Mg, Ca, Cu, and %K, %Mg, %Ca, and %Na were associated with high disease severity, whereas cation exchange capacity (CEC) and Al were correlated with low disease severity soils. In Ontario, high Mn content was strongly correlated with low disease severity soils, whereas %K and organic matter content were correlated with disease severity. Partitioning samples into presence or absence of the TxtA PCR product with corresponding high or low severity showed further significant relationships in the data. There was an excellent correlation between Streptomyces spp. presence as detected by PCR and disease severity in PEI soils; however, the relationship was not as clear in Ontario soils, where many PCR-positive soils had low disease incidence. Principal component and partial least square analysis indicated that disease severity was predicted by soil factors such as organic matter, CEC, pH, Al, %Ca, %Mg, and %K for PEI but not for Ontario soils. The data reveal that the relationship between scab severity and soil chemical components is complex and potentially soil specific.
