Pain and new cultural diseases
Authors: Ehlers Lise 
Published: June 2007

Abstract— The purpose of this article is to recount a piece of medical history, even though it has been told many times before.Everyone has heard about patients who visit their doctors time and again with physical complaints without the physician being able to find an adequate organic cause. The oldest descriptions of this illness can be found on ancient Egyptian papyrus rolls, dating back to about the year 1900 BC (Shorter F. A history of psychosomatic illness in the modern era. New York: Macmillan;1992). The need to tell these stories repeatedly can be attributed to the chameleonic nature of the illness which is difficult to spot because of its changing expression, which one could say takes on the appearance of its surroundings. Throughout history, humans have had the capacity to develop symptoms almost identical with the real diseases of the time. The term somatize is often used descriptively about patients with physical complaints without any recognizable organic basis. Shorter proposes that mankind has a shared “symptom‐pool” containing all existing symptoms. Patients who convert their mental state into bodily symptoms ‐ somatization ‐ take their symptoms from this symptom‐pool, albeit it is possible for new symptoms to emerge. For centuries patients have presented with sensory symptoms such as paresthesias. In the 19th century patients began to exhibit motorial symptoms with attacks of hysteria. According to Shorter's theory, this multitude of manifestations should be perceived as culturally determined or as different expressions of the same underlying phenomenon.

Potočnik I, Bajrović F. Failure of inferior alveolar nerve block in endodontics. Endod Dent Traumatol 1999; 15: 247–251. © Munksgaard, 1999.Abstract — Analgesia is essential for successful completion of modern dental procedures. Standard inferior alveolar nerve block (IANB) is the primary method used to achieve mandibular analgesia. Difficulty experienced in obtaining satisfactory analgesia after IANB, especially of an acutely inflamed mandibular molar, remains a common clinical problem. Even when a proper technique is employed, clinical studies show that IANB fails in approximately 30% to 45% of cases. The reasons for failure are not fully understood. Anatomical considerations and abnormal physiological responses in the presence of inflammation as explanations for IANB failure are discussed in this paper.

Shumayrikh NM, Adenubi JO. Clinical evaluation of glutaraldehyde with calcium hydroxide and glutaraldehyde with zinc oxide eugenol in pulpotomy of primary molars. Endod Dent Traumatol 1999; 15: 259–264. © Munksgaard, 1999.Abstract — The objectives of this study were to clinically evaluate the effectiveness of 2% buffered glutaraldehyde in pulpotomies of human primary molars and to compare the success rate of glutaraldehyde with calcium hydroxide and glutaraldehyde with zinc oxide eugenol as dressing material on the radicular pulp. Pulpotomies were completed on 61 primary molars in 19 children. The teeth were divided into two groups by random allocation. One group had a dressing of zinc oxide‐eugenol base (IRM) incorporated with one drop of 2% buffered glutaraldehyde while the other group had a dressing of calcium hydroxide base incorporated with one drop of 2% buffered glutaraldehyde after the initial placement of 2% buffered glutaraldehyde on cotton pellet for 3 min. All teeth had light‐curing compomer (Dyract) placed over the dressing material followed by a stainless steel crown restoration within 1 or 2 weeks after the pulpotomy. Blind clinical and radiographic evaluations of 57 teeth available after 12 months showed a success rate of 92.9% and 73.6% respectively. The clinical and radiographic success rates for glutaraldehyde/zinc oxide eugenol pulpotomies were 96.5% and 75.8% respectively while those for glutaraldehyde‐calcium hydroxide were 89.2% and 71.4%. There was no statistically significant difference between the two groups either clinically or radiographi‐cally. The overall clinical success rate suggested that 2% buffered glutaraldehyde was an effective agent in the pulpotomy of human primary molars.

Published: June 2007

SummaryIn this study, we describe a simple and rapid agglutination test for the detection of PCR products prior to the application of specific hybridization by sequence‐specific oligonucleotide typing. This test is based on the particle gel agglutination immunoassay, incorporating biotinylated primers and streptavidin particles. Visually detectable agglutination was only observed in samples which contained the specific amplification products. The results obtained by the new test were in accordance with those obtained by standard gel electrophoresis in all cases that have been tested to date.
Lack of association between three promoter polymorphisms of PTGDR gene and asthma in a Chinese Han population

Published: June 2007

SummaryThe PTGDR gene has been suggested to be an asthma susceptibility gene in previous genome‐wide linkage studies as well as in functional studies in a mouse model of asthma. Recently, promoter polymorphisms of the PTGDR gene have been reported to be associated with asthma in American and European populations. In order to determine the association of PTGDR promoter polymorphisms and asthma susceptibility in a Chinese Han population, three promoter single nucleotide polymorphisms (SNP) –549T/C, –441C/T, and –197T/C were genotyped in 336 patients with asthma and 264 healthy controls. Asthma was diagnosed according to the American Thoracic Society (ATS) criteria. SNPs –549T/C and –441C/T were genotyped by Tetra‐primer Amplification Refractory Mutation System PCR method and –197T/C by polymerase chain reaction‐restriction fragment length polymorphism method. Unlike the results observed in American and European populations, none of the three SNPs nor any haplotypes in the PTGDR promoter region were found to be associated with asthma susceptibility in this Chinese Han population (all P‐value > 0.05). The frequencies for both high‐transcriptional‐efficiency haplotype (CCC) and low‐transcriptional‐efficiency haplotype (TCT) were lower than 1% in patients and controls, significantly different from those observed in American and European populations. These results suggest that the three PTGDR gene promoter polymorphisms studied are not important risk factors for asthma susceptibility in the Chinese Han population.
GENETIC, ENVIRONMENTAL, AND MATURITY EFFECTS ON PECAN KERNEL LIPID, FATTY ACID, TOCOPHEROL, AND PROTEIN COMPOSITION
Authors: RUDOLPH C. J. , ODELL G. V. , HINRICHS H. A. , HOPFER D. A. , KAYS S. J. 
Published: June 2007

AbstractConcentrations of kernel oil, fatty acids, protein, and tocopherols were analyzed in 70 cultivars and selections to assess genetic, environmental, and maturity effects on composition. The most abundant fatty acids in pecan kernels were oleic > linoleic > palmitic > stearic > linolenic, and their concentrations varied with genotype, maturity, and year of production. The concentration of oil and protein in individual lines ranged from 60 to 76% and 7 to 17%, respectively. The lipid composition of 8 individual cultivars varied substantially due to production year, with the degree of variation being cultivar dependent. An inverse linear relationship was found between the concentration of oleic and linoleic acids. During maturation, there was a general decline in linoleic acid with a commensurate increase in oleic, yielding a progressively more mono‐unsaturated oil.
CHEMICAL CHANGES IN PECAN OILS DURING OXIDATION
Authors: RUDOLPH C. J. , ODELL G. V. , HINRICHS H. A. , THOMSON H. J. , KAYS S. J. 
Published: June 2007

AbstractChemical changes that occur during oxidation of pecan oils were investigated. During oxidation, the tocopherol concentration of the oils decreased and the oils discolored, changing from yellow to reddish and eventually becoming colorless. Changes in color were followed by a rapid increase in rancidity products and a corresponding decrease in linoleic acid concentration. Introduction of exogenous β‐carotene into decolorized pecan oil increased oxidative stability. Addition of the autioxidant tocopherol to the oil increased oxidative stability by a significant amount over that of β‐carotene. Keeping time of pecan oils could be increased by 50% with the addition of 800 μg‐tocopherol gm‐1 oil. Linoleic acid concentration appears to be the primary endogenous factor in the degradation of pecan oils after harvest. Endogenous tocopherol concentrations in pecan kernels were low and not closely related to the potential keeping time of the oil.The results suggest that the oxidative stability of pecan kernels may be proportional to the percent linoleic acid in the oil. Percent oleic and linoleic acid, tocopherol content, and keeping time were determined for 70 cultivars and unnamed selections of pecans.

Authors: ROURA SARA INÉS , MOREIRA MARÍA DEL ROSARIO , VALLE CARLOS ENRIQUE DEL 
Published: June 2007

ABSTRACTThe shelf‐life of fresh‐like ready‐to‐use diced squash during storage for 16 days at 10–12C and 95% of relative humidity was investigated. The ascorbic acid (AA) content, moisture, soluble solid content, titratable acidity, pH, weight loss and microbiological counts were determined. At the end of storage, a 1.5% weight loss was observed. Water content did not show significant changes during storage. The soluble solids content and the Brix/titratable acidity ratios increased during storage, following a linear correlation. The evolution of AA content followed a 2° polynomial correlation, with a maximum between 7–9 days of storage and a final value of 17 mg AA/100 g of fresh weight. The total microbial count increased continuously throughout storage but showed an acceptable level until day 10.

Authors: MASKAT MOHAMAD YUSOF , KERR WILLIAM LLOYD 
Published: June 2007

ABSTRACTThe effect of particle size on coating adhesion was measured for battered chicken breasts. Bread crumbs were separated into small (≤ 250 μm), medium (250 μm‐850 μm), and large (> 850 μm) particles. Chicken breasts were battered, breaded, and deep‐fat fried for 240 s at 160C. Fried products were analyzed for coating adhesion, moisture content, and yield parameters. Coating adhesion was highest in coatings formed from small particle size breading, and lowest in those made from large particle size breading. Chicken breasts coated using small particle size breading had higher moisture in the surface region of the meat as well as in the coating. SEM of the coatings showed greater merging between the breading and the batter with decreasing breading particle size. No significant differences were observed in coating pickup, cooking loss, or yield between samples coated with different particle size breading.
EFFECTS OF PRESTORAGE DRY AND HUMID HOT AIR TREATMENTS ON THE QUALITY, TRIGLYCERIDES AND TOCOPHEROL CONTENTS IN ‘HASS’ AVOCADO FRUIT
Authors: ORNELAS P. J. DE JESUS , YAHIA ELHADI M. 
Published: June 2007

ABSTRACT‘Hass’ avocado fruit were heated with dry (50% RH) or moist (95% RH) forced air at 38Cfor 6 h and then stored at 5C and 85% RHfor up to 8 weeks. Fruit were evaluated weekly for quality and for the content of three triglycerides and three tocopherols. Heated fruit had higher weight loss. The nonheated fruit and those heated with dry air displayed the best external quality. Fruit heated with dry air exhibited the best internal quality and the lowest chilling injury incidence. The respiration rate was more intense in fruit heated with moist air. Fruit firmness immediately after harvest was 51N, but decreased to less than 20 N at the end of the storage period in the three treatments. The analysis of triglycerides and tocopherols showed that the 1,2‐Dilinoleil‐3‐Oleil‐Glycerol and α‐tocopherol were the most abundant compounds. Therefore, postharvest treatment with dry forced hot air before storage or transport reduces the incidence of chilling injury, and decreases quality deterioration in ‘Hass’ avocado fruit.

Published: June 2007

ABSTRACTThe flavor extract components of malted ‘acha’ (Digitaria exilis), which have not been studied prior to this report, were determined by gas chromatography with a mass selective detector. Volatile compounds were identified with a NBS 43 K.1 mass spectra library by Probability Based on Matching (PBM). A total of 14 peaks were detected and identified in the malted sample.The volatiles included, four aldehydes, one aromatic compound, an ester, a terpene, one aliphatic alcohol, five heterocyclic compounds of six membered rings. Quantitatively, heterocyclic compounds were the most abundant class of compounds identified. Six compounds, ethylacetate, 1‐hydroxy‐2‐propanone, hexanal, pyrazine, 2, 5‐dimethylpyrazine and 2, 3‐dimethylpyrazine were identified as potential contributors to the flavor of malted acha. There was not a significant difference between the aroma quality of acha and crystal malt.

Published: June 2007

AbstractThe mealybug Phenacoccus gossypiphilous (Stanley) played havoc with the cotton crop in Pakistan during 2005. To control this pest, insecticides of different groups were evaluated in both the laboratory and in field conditions. In the laboratory, bifenthrin, profenofos and chlorpyrifos proved to be the best insecticides for mealybug control, based on their susceptibility with the leaf dip method for their LC50. In field conditions, the recommended application rates of methomyl, profenofos and chlorpyrifos provided the best control: the lethal time studies proved their efficiency for better and timely control of this sporadic pest. The present study has shown that the insecticides tested, in particular profenofos, chlorpyrifos, methomyl and bifenthrin, provide satisfactory control of the cotton mealybug. The control of the insect pest complex throughout the cotton crop predominantly depends on wise and justified use of these chemicals, and necessitates development of an integrated pest management strategy.

Published: June 2007

AbstractIn this study the effects of photoperiod and hibernation duration on the lifespan of Bombus terrestris queens were examined. Hibernation durations of 2.0, 2.5, 3.0, 3.5 and 4.0 months were studied, as were photoperiods of 0 h light : 24 h dark (LD 0:24), LD 8:16, LD 16:8 and LD 24:0. The queens that hibernated for 2.5 months and were exposed to 1 week of LD 8:16 had the highest survival rate (89.3%); the lowest survival rate was found in queens that hibernated for 4.0 months and were reared at LD 24:0. Photoperiod and hibernation duration had significant effects on egg predation by founding queens, competition between queens and workers, and emergence of sexual queens. Hibernation durations of 2.5 and 3.0 months and a photoperiod of LD 8:16 resulted in a significantly longer lifespan of B. terrestris.
Seasonal prevalence of the Culex pipiens group (Diptera: Culicidae) larvae occurring in a puddle in the basement of an apartment building
Authors: SOHN Seok Rak 
Published: June 2007

AbstractThe seasonal prevalence of the Culex pipiens group larvae occurring in a puddle in the basement of an apartment building was investigated from June 1993 to May 1994 (Period I), and from June 1994 to May 1995 (Period II). Totals of 25 237 individuals in Period I and 4989 individuals in Period II were collected: they were all C. pipiens group larvae, most of which were C. pipiens molestus. In Period I, the larvae occurred at a relatively low density in the hot months July and August; density began to increase from the cooler late September, peaked in late November, and was maintained at a high level until the third week of December. In Period II, in which mean air temperature was 5°C higher as of July and August than in Period I, larvae sharply decreased in number by one‐fifth of the total volume in Period I, and showed a peak density in the third week of July, and the peak continued until mid‐December. In Period I, the low temperature was favorable for oviposition activity of C. pipiens molestus, and accounts for the higher density of larvae in Period I than in Period II. C. pipiens molestus mostly stopped laying eggs between early December and late January. Larvae were not collected in March and April 1994 and in April 1995. However, considering that adult mosquitoes had been collected throughout the two periods except in March 1994, adults of C. pipiens molestus are thought to appear throughout the year.

Authors: CHO Youngho , KWON Ohseok , NAM Sang‐Ho 
Published: June 2007

AbstractThe life cycle ofGlyptapanteles liparidiswas 23.75 ± 1.26, 21.95 ± 2.44 and 20.83 ± 0.78 days when fed on the first, second and third instar larvae ofAcronicta rumicis, respectively. Although insufficient numbers hindered statistical analysis, the life cycle ofG. liparidisappeared to be shortest, 19 days, when fed on fourth instar larvae. The life cycle ofG. liparidistends to shorten as the larvae ofA. rumicisfed upon are more advanced. The body length, forewing length and head capsule width of femaleG. liparidisfed on first instar larvae ofA. rumiciswere greater than those of males, while the antennae of males were longer than those of females. When fed on second instar larvae, there was no difference in body length and head capsule width between males and females, but the male antennae were longer than the female, and the female forewings were longer than the male. When fed on third instar larvae, there was no significant difference in head capsule width between the sexes, but female body length and forewing length were greater than the male, and the male antennae were longer than the female. On the whole, females were bigger than males in terms of body length and forewing length, while antennae of the males were longer than those of the females. There was no difference in head capsule width between males and females. Body length, antenna length, forewing length and head capsule width of male and femaleG. liparidiswere relatively larger when fed on first instar larvae ofA. rumicisthan when fed on second and third instar larvae.

Published: June 2007

Background:  The asialoglycoprotein receptor (ASGP‐R) is abundantly expressed on the sinusoidal surfaces of hepatocytes. However, the majority of hepatocellular carcinomas (HCC) lack ASGP‐R on their cell surface membranes. We describe three cases of HCC showing increased expression of ASGP‐R in comparison with the surrounding liver tissue.Methods:  We performed technetium‐99m‐diethylenetriaminepentaacetic acid‐galactosyl human serum albumin (99mTc‐GSA) single photon emission computed tomography (SPECT) analysis on patients with HCC. Three cases of HCC showing enhanced accumulation of 99mTc‐GSA were included in the present study. Histopathological and radiological examinations of the HCC were conducted. The three affected patients were all female and over 60 years old.Results:  Computed tomography (CT) angiography or dynamic CT showed hypo‐enhancement of the tumors during the hepatic arterial to portal phases. Patient 1 received percutaneous ethanol injection therapy and died 5 years later because of chronic renal failure. Patient 2 underwent surgeryand is currently healthy 5 years after the operation. Patient 3 underwent percutaneous ethanol injection therapy and died 4 years later because of a newly occurred HCC to another part of the liver. Histopathological examination showed well‐differentiated HCC in all three cases. Immunohistochemical examination showed that the expression of ASGP‐R was higher in the HCC than in the non‐tumorous liver tissue.Conclusion:  We have named the HCC of this type ASGP‐Roma. ASGP‐Roma is well‐differentiated HCC, shows CT findings that are atypical of HCC, and is diagnosed by 99mTc‐GSA SPECT analysis. We propose that ASGP‐Roma be placed in a special category among well‐differentiated HCC.
