AbstractAims/Introduction:  The combination of hypertension with diabetes mellitus (DM) has been recognized as a critical risk factor for cardiovascular disease (CVD). We investigated the blood pressure levels in hypertensive patients with DM (HDM patients) compared with those without DM (HnDM patients). Furthermore, we examined the effect of risk factors, including chronic kidney disease (CKD) and stroke, on the management of both office blood pressure (OBP) and morning home blood pressure (MHBP).Materials and Methods:  OBP and MHBP were evaluated in 1230 essential hypertensive patients in 30 institutions. Among them, 366 (30%) were complicated with DM.Results:  The ratio of masked hypertensives whose systolic OBP was <140 mmHg and systolic MHBP was more than 135 mmHg in HDM patients was significantly higher than that in HnDM patients (P < 0.02). HDM patients had significantly lower systolic and diastolic OBP and diastolic MHBP than HnDM patients (P < 0.05, respectively). However, systolic MHBP in HDM patients tended to be higher compared with HnDM patients (P = 0.0623). A stratified analysis showed that HDM patients with CKD or stroke had significantly higher systolic MHBP than others (P < 0.05, respectively). The adjusted odds ratio for morning hypertension defined by a systolic MHBP more than 135 mmHg was significantly higher in the HDM patients with CKD (1.98) compared with HnDM patients without CKD (reference).Conclusions:  Diabetes, CKD and stroke are risk factors for MHBP. More intensive treatment is needed to achieve the thera‐peutic goal for systolic MHBP in HDM patients, especially those who are complicated with CKD or stroke.

Abstract
Loss-of-function mutations in the human RecQ helicase genes WRN and BLM respectively cause the genetic instability/cancer predisposition syndromes Werner syndrome and Bloom syndrome. To identify common and unique functions of WRN and BLM, we systematically analyzed cell proliferation, cell survival, and genomic damage in isogenic cell lines depleted of WRN, BLM, or both proteins. Cell proliferation and survival were assessed before and after treatment with camptothecin, cis-diamminedichloroplatinum(II), hydroxyurea, or 5-fluorouracil. Genomic damage was assessed, before and after replication arrest, by γ-H2AX staining, which was quantified at the single-cell level by flow cytometry. Cell proliferation was affected strongly by the extent of WRN and/or BLM depletion, and more strongly by BLM than by WRN depletion (P = 0.005). The proliferation of WRN/BLM-codepleted cells, in contrast, did not differ from BLM-depleted cells (P = 0.34). BLM-depleted and WRN/BLM-codepleted cells had comparably impaired survival after DNA damage, whereas WRN-depleted cells displayed a distinct pattern of sensitivity to DNA damage. BLM-depleted and WRN/BLM-codepleted cells had similar, significantly higher γ-H2AX induction levels than did WRN-depleted cells. Our results provide new information on the role of WRN and BLM in determining cell proliferation, cell survival, and genomic damage after chemotherapeutic DNA damage or replication arrest. We also provide new information on functional redundancy between WRN and BLM. These results provide a strong rationale for further developing WRN and BLM as biomarkers of tumor chemotherapeutic responsiveness. Cancer Res; 70(16); 6548–55. ©2010 AACR.
Sulfur Removed from Soils by Field Crops1
Authors: Kamprath E. J. , Nelson W. L. , Fitts J. W. 
Published: July 2010

SypnosisMore organic sulfur than inorganic sulfate was contained in the surface horizons of a Durham and Marlboro soil. In the lower horizons there was an accumulation of sulfate in both soils. On the Durham soil sulfur deficiencies were exhibited. by cotton and tobacco early in the growing season. Only cotton gave a response to additions of gypsum. Cotton and soybeans removed considerably more sulfur than tobacco or corn. Availability of soil sulfur was evaluated by use of yield of sulfur Curves.
Effect of Foliar Spraying of Pawnee Wheat With Urea Solutions on Yield, Protein Content, and Protein Quality1
Authors: Finney K. F. , Meyer J. W. , Smith F. W. , Fryer H. C. 
Published: July 2010

SynopsisA new approach to studying protein quality is suggested by the capability of the wheat plant to take up, translocate, and synthesize gluten protein from the urea nitrogen sprayed on the leaves. Data show the effect of time of spraying, number of sprayings, and concentration of urea on wheat yield, test weight, and protein content and quality.
Studies on the Importance of the Yellow‐dwarf Virus1
Authors: Suneson C. A. , Ramage R. T. 
Published: July 2010

SynopsisCalifornia's commercial varieties of barley, oats, and wheat showed similar yield reductions from yellow‐dwarf virus for which there is no universal diagnostic symptom. American barley varieties in general were more susceptible than California's. Since significant yield reductions were common, and reductions above 70% not unusual for susceptible varieties, yellow dwarf must be ranked as a major cereal crops disease.
Zinc Levels in Relation to Zinc Content and Growth of Corn1
Authors: Hiatt A. J. , Massey H. F. 
Published: July 2010

SynopsisThe zinc concentration in corn was related to its available supply. Plants showing severe deficiency symptoms were stunted and had a relatively high zinc concentration; lowest zinc concentration occurred when deficiency symptoms were mild and growth better. Two possible explanations for these anomalous results are discussed.
Nitrate Accumulation in Everglades Forages1
Authors: Kretschmer Albert E. 
Published: July 2010

SynopsisOats and Italian ryegrass accumulate large quantities of nitrate but permanent pasture grasses and legumes do not. Oat stems contained more nitrate than leaves. Winter forages following summer clean fallow contained more nitrate than those following weeds. Time of season, daily low temperatures, and variations between daily low and high temperatures also affected nitrate contents.
Relation of Fertilizer Placement to Nutrient Uptake and Crop Yield: II. Effects of Row Potassium, Potassium Soil‐Level, and Precipitation1
Authors: Barber Stanley A. 
Published: July 2010

SynopsisBoth potassium soil‐level and row potassium treatments were about equally effective in supplying potassium for a corn‐soybean‐wheat‐hay rotation. Relative increases in corn and soybean yields due to potassium fertilization were inversely correlated with the amount of rainfall which occurred during the growing season.
Crop Response to Zinc Fertilization as Influenced by Lime and Phosphorus Applications1
Authors: Seatz Lloyd F. , Sterges Athan J. , Kramer James C. 
Published: July 2010

SynopsisResponse of flax and sorghum to zinc fertilization increased as the liming rate was increased from 2 to 6 tons of CaCO3 per 2 million pounds of Hartsells soil. Phosphorus fertilization did not affect zinc response. Best growth was obtained when the Ca/Mg ratio of the liming material as 2/1.
Cytoplasmic Effects on Agronomic Characters in a Double‐Cross Maize Hybrid1
Authors: Fleming A. A. , Kozelnicky G. M. , Browne E. B. 
Published: July 2010

SynopsisSignificant cytoplasmic effects were obtained in a double‐cross maize hybrid for the agronomic characters: yield, silking, ear and plant heights, erect plants, and budworm damage. All cytoplasms did not interact with the genotype in the same manner. These results apparently justify consideration of the source of cytoplasm in a breeding program. In most cases when differences occurred between the cytoplasmic effects, the performance of the hybrid was in the direction of the inbred performance.
Effect of Soil Moisture Level on Root Distribution of Cool‐Season Forage Species1
Authors: Bennett Orus L. , Doss Basil D. 
Published: July 2010

SynopsisEffective rooting depth decreased as soil moisture level increased. A high percentage of the roots was found in the surface 12 inches of soil for all species regardless of soil moisture level. Soil moisture extraction was used with reasonable accuracy to estimate effective rooting depth.
The Effect of Seeding Rate and Rate of Nitrogen Application on Winter Wheat Varieties with Different Characteristics1
Authors: Pendleton J. W. , Dungan G. H. 
Published: July 2010

SynopsisVarieties showed a different yield response to seeding rates and to rates of nitrogen application. This response did not seem to be correlated with varietal morphological characteristics. Variety selection controlled more agronomic characteristics than either rate of nitrogen application or rate of seeding.
Sediment Delivery Ratio Studies in Mississippi. I. A Preliminary Report1
Authors: Spraberry James A. , Woodburn Russell , McHenry J. Roger 
Published: July 2010

SynopsisComputed gross erosion for a number of north Mississippi watersheds was compared with the measured sediment yields. The computed sediment delivery percentages varied greatly for the different watersheds but these differences were not correlated with any measured physical parameter of the watersheds.
Evaluation of Semidwarf Selections from a Spring Wheat Breeding Program1
Authors: Mcneal F. H. , Berg M. A. , Klages M. G. 
Published: July 2010

SynopsisSemidwarf selections averaged 5 to 9 inches shorter than standard varieties, depending on location of the planting. Yields and test weights were essentially equal, indicating that high yielding, short‐straw spring wheats can be produced. The shortness of the semidwarfs is due chiefly to shorter peduncles but the other internodes also are shorter. Both types responded similarly to nitrogen fertilizer, but the standard varied more in plant height than the semidwarf.
Development and Composition of Spring Wheat as Influenced by Nitrogen and Phosphorus Fertilization1
Authors: Boatwright G. O. , Haas H. J. 
Published: July 2010

SynopsisDry matter production and N uptake by wheat reached a maximum at heading, soft dough, and maturity on NP, N, and unfertilized plots, respectively. Maximum P uptake occurred by heading irrespective of treatment. Nitrogen and phosphorus in the grain were derived primarily by translocation from leaves, stems, and chaff, and the amount was influenced by fertilization.
Legume Establishments as Related to the Presence or Absence of an Oat Companion Crop1
Authors: Peters Robert A. 
Published: July 2010

SynopsisWhen measured at the time the oats were removed for silage, legume yields were lowest when seeded with oats. Recovery during a favorable year (1959) was rapid for alfalfa, red clover, and Ladino clover. Yields of birdsfoot trefoil remained depressed. During a dry year (1957) alfalfa regrowth was satisfactory following seeding competition with weeds but not with oats. It was concluded that oats frequently will be much more competitive than the weed growth which will flourish in their absence.

Authors: Madison John H. , Hagan Robert M. 
Published: July 2010

SynopsisHeight of cut, irrigation frequency, and aeration treatments all produced significant differences in water extraction. Extraction by 3‐ and 4‐year‐old sod occurred almost entirely in the top 20 inches of the soil.
Some Observations on the Movement of Water to Plant Roots1
Authors: Gardner W. R. , Ehlig C. F. 
Published: July 2010

SynopsisAn equation describing the uptake of water by plants is described. Greenhouse experiments support the equation and show that the lower limit of water availability is determined by the rate of water transmission through the soil to the plant roots. An appreciable amount of water is shown to move vertically in the root zone.
Growth of Ryegrass as Influenced by Temperature and Solar Radiation1
Authors: Weihing Ralph M. 
Published: July 2010

SynopsisSimple correlation was 0.84 between growth and daily mean temperature within the range of 47° to 67° F. It was 0.74 between growth and daily mean solar radiation within the range of 214 and 491 langleys. Several multiple regressions of growth on various expressions of temperature and solar radiation were studied. The equation Ŷ = −495.72 + 17.0285x1 − 0.1306x2, where X1 = temperature and x2 = temperature2, appeared best suited for predicting growth rates of forage in ryegrass pastures.
Selenium Uptake and Conversion by Certain Crop Plants1
Authors: Hamilton J. W. , Beath O. A. 
Published: July 2010

SynopsisAll plants studied possess the ability to absorb selenium from the soil. This selenium is metabolized and stored in the plant tissue in sufficient quantities to render the plant material capable of producing toxic effects when eaten by animals. All plants and, in some instances, their seeds or grains contained both organic and inorganic selenium. Flaxseed, safflower seed, and the root portion of sugar beets contained relatively low levels. Sunflower plants possessed the highest selenium‐absorbing ability.

Authors: Yermanos D. M. , Hall B. J. , Burge W. 
Published: July 2010

SynopsisEight iron chelate formulations applied on field plots of flax and safflower did not increase seed yields. Seed oil content and iodine value of oil were not affected except in one case when an increase in iodine value was associated with a decrease in seed yield. Nitrogen fertilization depressed iodine value of oil and seed oil content but increased seed yields.
Influence of Cultural Treatments on Seed Production of Intermediate Wheatgrass (Agropyron intermedium (Host) Beauv.)1
Authors: Canode C. L. 
Published: July 2010

SynopsisBurning of the straw and stubble after harvest was beneficial in maintaining high seed yields of intermediate wheatgrass. Mechanical removal of every other foot of vegetation in the row produced seed yields equal to burning. The effects of burning and mechanical thinning appeared to be additive. Increasing the rate of nitrogen was not effective in maintaining seed production as the stands became older.
Soil Components Determining Bensulide Phytotoxicity
Authors: Lynd J. Q. , Rieck C. E. , Santelmann P. W. 
Published: July 2010

AbstractOrganic matter amendment, soil reaction and cation exchange capacity interactions with Eufaula sand and Brewer clay loam were determined for bensulide, S‐(O, O‐diisopropyl phosphorodithioate) of N‐(2‐mercaptoethyl) benezenesulfonamide. Herbicidal effectiveness for crabgrass growth was reduced with ground straw and mimosa soil additions. Acid soil reactions reduced bensulide activity on both soil types. Reduced phytotoxicity occurred with increased soil cation exchange capacities in Eufaula‐Brewer soil mixtures.
Incidence of Smut at Three Corn Plant Populations1
Authors: Rutger J. N. , Risius M. L. 
Published: July 2010

AbstractAverage smut infection of a group of 30 corn hybrids tested in 5 locations increased as plant populations were increased from 20,800 to 29,200 plants per acre. A highly significant (1% level) hybrid × population interaction for incidence of smut indicated that hybrids respond differentially to planting rates.Although most of the hybrids were believed to be relatively tolerant to smut, highly significant hybrid differences in infection were observed. Smut infection, averaged over locations and populations, ranged from a low of 2.9% for hybrid 16 to a high of 18.3% for hybrid 26.
Nitrate Accumulations in Forage Crops1
Authors: Murphy L. S. , Smith G. E. 
Published: July 2010

AbstractThe effects of N and P fertilization rates and stage of plant maturity on the nitrate‐N content of nine forage species were studied over a 2‐year period. Species included in the investigations were orchardgrass, tall fescue, bromegrass, bluegrass, timothy, sudangrass, wheat, alfalfa, and ladino clover. Nitrate‐N was determined on hot water extracts of dried plant material by the phenoldisulfonic acid method.Of the species under study, sudangrass accumulated nitrate‐N to the greatest extent. It was closely followed by orchardgrass and fescue. Bromegrass, timothy, and ladino clover accumulated intermediate amounts of nitrate‐N. Alfalfa and wheat accumulated little of this form of nitrogen.Increased N fertilization had a direct effect on nitrate‐N accumulation. Phosphorus fertilization had little if any effect upon the nitrate‐N contents of the various species.Advancing plant maturity was associated with a decline in the nitrate‐N content of most species.
Performance of Four Pasture Mixtures Defoliated by Mowing or Grazing with Cattle or Sheep1
Authors: Matches Arthur G. 
Published: July 2010

AbstractEvaluation of pasture mixtures in small‐plot clipping trials may be criticized since plant responses after mowing may not be the same as those after grazing. In this investigation, four pasture mixtures (tall fescue‐ladino clover, orchardgrass‐ladino clover, smooth bromegrass‐alfalfa, and Kentucky bluegrass‐birdsfoot trefoil) were evaluated under mower, sheep, and cattle defoliation. Only yields of orchardgrass‐ladino clover were significantly influenced by method of defoliation; and a significant defoliation method ✕ mixture interaction was due largely to the response of this mixture. Yields of orchardgrass‐ladino clover under mowing were significantly less than yields under animal defoliation. Botanical composition of the bromegrass‐alfalfa and bluegrass‐trefoil mixtures did not appear to be influenced by method of defoliation. Stands of ladino clover were lost early in the investigation. Tall fescue and orchardgrass appeared to be more competitive with weeds under cattle defoliation than when defoliated by mowing or grazing with sheep. Yield rankings of the four pasture mixtures were similar within the three methods of defoliation. It appears that herbage yields obtained in small plot clipping trials are reliable for predicting performance of forages under grazing conditions.
Effect of Gaseous Composition of Root Environment upon Root Development and Growth of Nicotiana tabacum L.1
Authors: Williamson R. E. , Splinter W. E. 
Published: July 2010

AbstractTobacco gaseous treatmentsThe extent of root and shoot injury of tobacco plants exposed to various gaseous treatments (O2, CO2, N2) in the root environment was determined by microscopic examination of roots, stem diameter changes, and shoot measurements. An attempt was also made to determine the relative importance of O2 deficiency and CO2 excess in causing the observed injury. The plants were grown in an environmental control chamber with roots in an intermittent solution mist in airtight chambers.Oxygen levels of 2.5%, with and without 18.5% CO2, the remainder being N2, caused no apparent reduction in root or shoot growth. One percent O2 plus 99% N2 treatments for 24 or 48 hours reduced the rate of growth during treatment; but the plants resumed a normal rate of growth during recovery. One percent O2 plus 20% CO2 plus 79% N2 treatments for 24 or 48 hours caused death of several root tips, chlorosis of the lower leaves, necrotic areas on some other leaves, and considerable reduction in the rate of growth during treatment. Treatments with pure N2 for 12 hours caused growth to cease for 60 hours. Treatments with pure N2 for 24 hours resulted in death of the root system within 4 days. Treatments with 21% CO2 for 24 hours killed the plants more quickly than did pure N2.
Influence of Precipitation, Soil Water, and Plant Population Interactions on Corn Grain Yields1
Authors: Holt R. F. , Timmons D. R. 
Published: July 2010

AbstractCorn grain yield response to different levels of soil water, precipitation, and plant population during the rapid growth period of corn was evaluated by multiple regression using 4 years' field data. For 17 locations showing a yield response to stand, multiple regression accounted for 91% of the variation in grain yields during the 4‐year period. Estimated corn yields from the developed equation varied from 0 to 8976 kg/ha for all possible combinations of the independent factors.The corn growth interval from 30‐cm plant height to silking was divided into two equal time periods. Precipitation received during the second period (late July and early August) exerted a greater influence on corn yields than did that received during the first period (early July). With increased precipitation during the two periods, the optimum part of the stand—yield curve shifted to correspondingly higher stands.
Zinc Nutrition of Alfalfa1
Authors: Lo Shitao Yie , Reisenauer H. M. 
Published: July 2010

AbstractThe influence of Zn supply on the yield and chemical composition of alfalfa grown with symbiotically fixed N or with nitrate N under conditions that provided relatively rapid or slow growth rates is reported. Nitrogen source had no effect on the relationship between relative yield and the concentration of Zn in the leaf tissues confirming the earlier conclusion that symbiotic N fixation is only indirectly influenced by the Zn nutrition of the host plant. Rate of growth influenced the level of Zn in the nutrient media required for maximum yield but did not affect the leaf Zn concentration associated with maximum production. Top yields were obtained with leaf Zn levels greater than 6 ppm. This value is approximately one‐third to one‐half that required for most other crops and explains the infrequent response of alfalfa to Zn fertilization.Observations and analyses of field grown alfalfa revealed no unusual ability of the crop to absorb or accumulate soil Zn and failed to explain the reported beneficial influences of alfalfa on the Zn nutrition of associated crops.
Method for Predicting Potassium Uptake by Grain Sorghum1
Authors: Hipp Billy W. , Thomas Grant W. 
Published: July 2010

AbstractA greenhouse experiment using nutrient solution culture with graded levels of K was used to determine the concentration of K required in grain sorghum leaves for optimum growth. It was determined that growth of grain sorghum is reduced if the leaf K concentration is much below 1.5% at the full bloom stage. A field study was made to relate soil K parameters from eight different soils to concentration of K in grain sorghum leaves at the full bloom stage of growth. The best method of predicting K uptake by plants included both solution K and exchangeable K. A correlation coefficient of 0.890 was obtained between percent K in leaves and solution K + log (1 + exchangeable K).

Published: July 2010

AbstractWater evaporated from vertical columns of Yolo loam, 100 cm long, for 200 days at ambient temperatures of 10, 20, or 30C ± 1C. Distribution of soil water was determined by gamma‐ray attenuation at 5‐cm intervals, concomitantly with determinations of soil water pressure. Values of capillary conductivity based upon measured fluxes and hydraulic gradients are presented, along with values of diffusivity based upon fluxes and water content gradients.
