Published: June 2007

Hilú RE, Zmener O. Mental nerve paresthesia associated with an amalgam filling: a case report. Endod Dent Traumatol 1999; 15: 291–293.© Munksgaard, 1999.Abstract — We present a case report in which a mental nerve paresthesia occurred in connection with an amalgam filling placed in direct contact with the pulp of a mandibular first molar. The main evidence for amalgam being the dominant etiological factor was the positive epicutaneous patch testing response to the components of the amalgam alloy, and the total remission of symptoms without further clinical complications after removal of the amalgam filling and subsequent endodontic therapy.

Endod Dent Traumatol 1999; 15: 294–296. © Munksgaard, 1999.Abstract — Dento‐facial injuries that occur prior to the eruption of teeth in the primary dentition are rare, but can result in damage to the primary dentition. We report a rare case where an injury to the anterior maxilla and mandible of an infant prior to primary tooth eruption resulted in hypoplasia, displacement and impaction of the primary dentition and damage to a developing permanent tooth.
Teaching & Learning Guide for: Jane Austen and the Public Sphere
Authors: Jones Chris 
Published: June 2007

Author Recommends: The Cambridge Companion to Jane Austen, edited by Edward Copeland and Juliet McMaster (Cambridge UP, 1997) has useful essays on ‘Class’ and ‘Money’ as well as ‘Style’ and on individual novels, reflecting a new awareness of Austen’s participation in a discourse rather wider than the initially domestic focus of her novels might suggest.Edward Said’s reading of Mansfield Park in the contexts of its significant silence over the West Indian plantation owned by Sir Thomas Bertram is one of the most contentious attempts to bring politics to Austen’s world, seen by many critics as ignorant or uninterested in wider issues. Said’s Culture and Imperialism (Vintage, 1995) has been variously challenged, including in John Sutherland’s Is Heathcliff a Murderer?: Puzzles in Nineteenth‐Century Fiction (Oxford UP, 1996).For a visual adaptation of the novel influenced by Said’s activation of its colonial subtext, see the film Mansfield Park directed by Patricia Rozema (1999).The journal Eighteenth Century Studies special issue on ‘The Public and the Nation’ (29, 1995), includes a number of relevant essays, including Lawrence E. Klein’s investigation of ‘Gender and the Public/Private Distinction in the Eighteenth Century: Some Questions about Evidence and Analytic Procedure’: Klein genders the Habermasian model and critiques binary assumptions of private‐female public‐male.Online Materials:The refereed online journal Romanticism on the Net has scholarly articles and reviews: http://www.ron.umontreal.ca/Jane Austen’s writings can be accessed online via http://www.pemberley.com/janeinfo/janewrit.html.

SummaryMutations in the human CC chemokine receptor 5 (CCR5) gene may alter the expression or function of the protein product, thereby altering chemokine binding/signalling or human immunodeficiency virus type 1 (HIV‐1) infection of the cells that normally express CCR5 protein. We performed a systematic survey of natural sequence variations in an 8.1‐kb region of the entire CCR5 gene as well as CCR2V64I in 50 Japanese subjects and evaluated the effects of those variations on CCR5 promoter activity. We also analysed CCR5 promoters and CCR2V64I in 80 more Japanese and 186 Thais. There was no 32‐bp deletion observed in Caucasians, but two types of non‐synonymous substitutions were found in CCR5 genes of Japanese. Our results showed several novel characteristics of the CCR2‐CCR5 haplotype structure that were not reported from studies on Caucasians and African‐Americans. Specifically, we were able to show that the G allele at position –2852 from the CCR5 open reading frame in Japanese and Thais is the representative of the CCR5 promoter haplotype that was reported to be associated with rapid progression to acquired immune deficiency syndrome (AIDS) in HIV‐1‐infected individuals. Furthermore, nearly all non‐synonymous polymorphisms in Japanese CCR5 occurred in haplotypes with elevated promoter activity. We thus hypothesized that there was a certain selective pressure favouring low levels of CCR5 expression during human evolution.

SummarySignificant associations between human leucocyte antigen (HLA)‐A and ‐B alleles and CD8+ T‐lymphocyte numbers have been reported in the literature in both healthy populations and in HFE‐haemochromatosis patients. In order to address whether HLA alleles themselves or alleles at linked genes are responsible for these associations, several genetic markers at the MHC class I region were typed on a population of 147 apparently healthy unrelated subjects phenotypically characterized for their CD8+ and CD4+ T‐lymphocyte numbers. By using a machine learning approach, a set of rules was generated that predict the number of CD8+ T‐lymphocyte numbers on the basis of the information of the D6S105 microsatellite alleles only. We demonstrate that the previously reported associations with HLA‐A and ‐B alleles are due to the presence of common long (up to 4 megabases long) haplotypes that increased in frequency recently due to positive selection and that encompass a region where a putative gene contributing to the setting of CD8+ T lymphocytes is located, in the neighbourhood of microsatellite locus D6S105, in the 6p21.3 region.
Association of polymorphisms of human leucocyte antigen‐DQA1 and DQB1 alleles with chronic hepatitis B virus infection, liver cirrhosis and hepatocellular carcinoma in Chinese
Authors: Liu C. , Cheng B. 
Published: June 2007

SummaryTo investigate whether human leucocyte antigen (HLA) class II DQA1 and DQB1 gene polymorphisms are associated with chronic hepatitis B virus (HBV) infection and development of HBV‐related liver cirrhosis (LC) and hepatocellular carcinoma (HCC), we detected the DQA1 and DQB1 allele polymorphisms in 168 HBV carriers (including 48 chronic hepatitis B, 42 LC and 78 HCC patients) and 100 controls who had recovered from HBV infection by using polymerase chain reaction amplification with sequence‐specific primers (PCR‐SSP). Our data suggest that DQA1*0102 and DQA1*0104 were associated with protection from chronic HBV infection (Pc = 0.003) and development of LC (Pc = 0.001), respectively, whereas DQB1*0201 conferred susceptible effect on chronic HBV infection (Pc = 0.008). We also found that DQA1*0601, DQB1*0601 and DQA1*0201 showed some susceptible effect on chronic HBV infection and LC, respectively, however, these associations were no longer significant after Bonferroni correction (Pc = 0.390, Pc = 0.475 and Pc = 0.140, respectively). No significant association has been found between DQA1 and DQB1 alleles and development of HCC. These results indicate that different subtypes of HLA‐DQA1 and DQB1 are associated with development of chronic HBV infection and LC, respectively, in Han Chinese population.

SummaryPerforin is one of the key effector molecules of cytotoxic T cells and natural killer cells. The influence of HLA‐DRB1 alleles on peripheral blood perforin‐positive CD4, CD8, CD16 and CD56 cells was studied by flow cytometry. HLA‐DRB1 typing was done in normal healthy subjects (NHS: n = 156) and patients with pulmonary tuberculosis (PTB: n = 102) by polymerase chain reaction‐based sequence‐specific oligonucleotide hybridization method. We observed a significantly decreased percentage of total perforin‐positive cells (per+) (P = 0.0004); CD8+/Per+ (P = 0.0005); CD16+/Per+ (P = 0.05) and CD56+/Per+ cells (P = 0.001) in HLA‐DR2‐positive PTB patients compared to non‐DR2 patients. Subtyping of HLA‐DR2‐positive subjects at the allelic level revealed that the percentage of CD8+/Per+ cells did not differ among DRB1*1501 and DRB1*1502 patients while a trend towards a decreased percentage of CD16+/Per+ and CD56+/Per+ cells was noticed in DRB1*1501 patients compared to DRB1*1502 patients. The present study suggests that HLA‐DR2 may be associated with down‐regulation of perforin‐positive cytotoxic lymphocytes and natural killer cells in pulmonary tuberculosis.

Published: June 2007

AbstractQuick breads were formulated to contain 0%, 40%, 50% or 60% Soy Protein Isolate and Fiber (SPI/Fiber), and yeast breads were formulated to contain 0%, 14%, 21% or 28% SPI/Fiber replacement for wheat flour. Physical and sensory data were collected. As SPI/fiber level increased, muffin batter specific gravity, baked product air cell number, Instron peak force to compress by 75%, a value, beany flavor, grain‐like flavor, aftertaste, moistness and denseness increased while muffin peak height at the crown, baked volume, L and b values, hue angle, sweetness and crumbliness decreased. There were significant negative correlations between increased level of SPI/fiber in muffins and acceptability of flavor and texture, as well as willingness to purchase or purchase the product at a higher price. As SPI/fiber level increased, bread dough pH after fermentation, air cell number, Instron peak force to compress by 75%, a and b values, beany flavor, grain‐like flavor, and aftertaste increased while loaf volume, peak height at the crown, L value, hue angle, cohesiveness and crumbliness decreased. There were significant negative correlation coefficients between level of SPI/fiber and acceptability of flavor and texture, as well as willingness to purchase the product or to purchase it at a higher price.

Published: June 2007

AbstractStudies were conducted to improve the texture and sensory qualities of raw jack fruit. Diced tender jack fruit was subjected to steam cooking (1 kg cm‐2 for 20 min) and oil frying at 150 ± 30C for 5 min and 180 ± 20C for 5 min, respectively. Minced mutton at 5% (w/w) of the jack fruit dice was incorporated into the curried recipe prepared from dice fried in oil at 150C to impart mutton flavor and tested for texture. The firmness of fried dice increased significantly as measured by peak force of 11.06 and 11.49 kg. cm‐2 compared to 0.33 kg. cm‐2 of steamcooked dice. Further, the sensory evaluation for texture and flavor of the samples in the curried recipe also revealed that the fry‐treated samples (at 150 ± 30C) were better in quality than steam‐cooked samples. The frying treatment of raw jack fruit dice increased the oil content of the dice (8.26% on FWB) compared to 0.6% in steamed dice. However, the treatment did not affect salt pick up.

Published: June 2007

AbstractSaffron the valuable stigma from flowers of Crocus sativus L, valued essentially for delicate flavor has specific testing methods for physical, chemical, microscopic parameters, in addition to pigments, and bitter principle but not for flavor. The flavor profile pattern as cob‐web diagrams are reported. The dose‐response relationship for saffron flavor (due to the principal flavor component, safranal) is established with n = 0.75 for a modified Stevens' equation. Importance of examination of flavor is highlighted for grading in view of new developments in postharvest technology and synthetic safranal entering the market. The GC peak identification of safranal by liquid and headspace GC and GC‐MS is demonstrated and confirmed from bioassay at the exit port by sniffing.
EFFECT OF POSTHARVEST HOT AIR AND FUNGICIDE TREATMENTS ON THE QUALITY OF ‘MARADOL’ PAPAYA (CARICA PAPAYA L.)
Authors: PÉREZ‐CARRILLO ESTHER , YAHIA ELHADI M. 
Published: June 2007

ABSTRACTPapaya (Carica papaya L.) fruit is very perishable with a maximum postharvest life of 4 weeks. The effect of forced moist (100% RH) or dry (50%) hot air with or without Thiabendazole (TBZ at 1.2 g active ingredient/L) on the chilling injury (CI), fungi development and quality of ‘Maradol’papaya fruit stored at 5C or 20C for up to 42 days was investigated. Moist hot air at 48.5C or 50C for 4 h caused fruit injury. Dry air at 48.5C for 4 h, alone or in combination with TBZ, decreased CI intensity and fungi development, and the best effect was achieved by combining dry heat treatment and TBZ, without causing negative effects on fruit quality and without causing heat injury. Hot air treatment, especially in combination with TBZ, decreased growth of inoculated Colletotrichum gloeosporioides. Trehalose was not detected in papaya, probably due to the presence of trehalase. Hot water treatment, with or without TBZ, did not cause any negative effect on the content of β‐carotene and lycopene.
QUALITY OF PACKED AND BIN STORED ‘ANJOU’ PEARS AS INFLUENCED BY STORAGE ATMOSPHERE AND TEMPERATURE
Authors: DRAKE S.R. , ELFVING D.C. 
Published: June 2007

ABSTRACTPacked pears (Pyrus communis‘d’‘Anjou’) were stored under four individual controlled atmosphere (CA) storage conditions (#1: CA of 1.5% O2 and < 1% CO2 at −1.5C; #2: CA of 1.5% O2 and < 1% CO2 at + 1.5C; #3: CA of 1.5% O2 and 3.0% CO2 at −1.5C; #4: CA of 1.5% O2 and 3.0% CO2 at + 1.5C). Loose pears in bins were stored under three CA storage conditions (#1: CA of 1.5% O2 and <1% CO2 at −1.5C; #2: CA of 1.5% O2 and 3.0% CO2 at −1.5C; #3: CA of 1.5% O2 and 3.0% CO2 at +1.5C). For packed pears, increased CO2 in the storage atmosphere resulted in retention of peel color, reduced firmness loss and enhanced subjective scores, particularly for finish and stem condition. Pears stored loose in bins, prior to packing in late January in an atmosphere containing 3.0% CO2 aided firmness retention, reduced scald and greatly enhanced subjective quality scores for appearance, finish and scuffing. Storing ‘Anjou’pears in a 3.0% CO2 atmosphere allows for storing pears loose in bin and packing in late January with little or no quality losses compared with using the standard 1.0% CO2 in the storage atmosphere.

Authors: KADAKAL ÇETIN , POYRAZOGLU E. SINAN , ARTIK NEVZAT , NAS SEBAHATTIN 
Published: June 2007

ABSTRACTThe effect of activated charcoals (0, 0.5, 1.0, 2.0 and 3.0 g/L of powdered and granular activated charcoals) on the content of several water‐soluble vitamins in apple juice was studied. Apple juice samples with activated carbon added were mixed for 0 (control), 5, 10, 20, and 30 min, respectively. The content of water‐soluble vitamins was analyzed by HPLC. Considerable reduction in ascorbic acid (Vit C), niacin, pyridoxine (Vitamin B6), thiamine (Vitamin B1) and biotin concentrations was found while there was a dramatic improvement in the color and clearness of apple juice. The highest decrement in water‐soluble vitamins was obtained at 3.0 g/L powdered activated charcoal. Statistical analysis of the data showed highly significant differences (P |< 0.05, P < 0.01) in the water soluble vitamins, color and clearness of the apple juice samples between the dosages of activated charcoals but no significant differences induced by the mixing periods.
Studies on the morphometry of the green peach aphid, Myzus persicae (Sulzer) (Homoptera: Aphididae)
Authors: DEVI Potshangbam Bijaya , SINGH Thangjam Kameshwor 
Published: June 2007

AbstractAphids are one of the most important groups of phytophagous insects because of their polyphenism, host alternation, heteroecious behavior and reproductive habits. Laboratory culture of the aphid Myzus persicae on the host plant Brassica pekinensis Hubner was maintained seasonally for biometrical studies. The metric analysis revealed gradual developmental changes from the first instar nymph to the adult stage in size, shape, and a number of characters. The transitional changes were sufficiently distinct to allow differentiation of each of the life stages irrespective of the season. A key to the nymphal stages of the pest is provided.

Applying insect transgenic technology: Scientific and regulatory experiences*
Authors: MILLER Thomas A. 
Published: June 2007

AbstractBiotechnology affords opportunities to develop new tools to treat pest and disease problems. When a given pest or disease problem has no satisfactory cure or treatment, usually only a technological breakthrough can provide one, but the process whereby this happens can be undefined and unpredictable. Furthermore, it is difficult to predict which methods will work at the outset, meaning that it is also difficult for funding agencies to determine which proposals to support. When a proposed solution is new and may involve genetic manipulation, it may also be hard for the public, as represented by regulatory agencies, to accept. In addition, when the application market is small, funding is modest. When the problem is major but periodic, as in the case of migratory locusts, funding, interest and attention cannot be easily found, focused or sustained. It is only when a problem is severe and economically compelling, such as Pierce's Disease of grapevine in southern California, that it is possible to concentrate funding, attention and sustained interest long enough to have a chance of finding a lasting solution.
Upregulation of cellular triacylglycerol – free fatty acid cycling by oleate is associated with long-term serum-free survival of human breast cancer cells
Authors: Przybytkowski Ewa , Joly Érik , Nolan Christopher J. , Hardy Serge , Francoeur Ann-Michele , Langelier Yves , Prentki Marc 
Published: June 2007

We previously showed that exogenous oleate protects human breast cancer cells against palmitate-induced apoptosis in part by increasing esterification of this free fatty acid (FFA) into triacylglycerol (TG). Here, we studied the mechanism whereby oleate protects these cells against apoptosis induced by serum withdrawal. The metabolism of FFA, TG, and glucose, in parallel with long-term cell survival in the absence of serum, was investigated in a panel of human breast cancer cell lines and in nontransformed MCF-10A cells after treatment with exogenous oleate. Short-term (3–24 h) exposure of MDA-MB-231 human breast cancer cells to exogenous oleate resulted in a dose-dependent long-term (10 day) serum-free survival that correlated with the accumulation of TG in lipid droplets and with upregulation of lipolysis. Both effects persisted for several days after oleate removal. Rapid TG lipolysis and FFA re-esterification, supported by high rates of glycolysis that provide the glycerol backbone for TG synthesis, are consistent with the presence of very active TG–FFA cycling in human breast cancer cells. Only the cancer cell lines capable of accumulating TG showed long-term serum-free survival after oleate treatment. The results suggest that upregulation of TG–FFA cycling induced by oleate may be involved in maintenance of human breast cancer cell survival.
Probing the role of the conserved β-II turn Pro-76/Gly-77 of mitochondrial cytochromec
Authors: Black Karen M. , Wallace Carmichael J.A. 
Published: June 2007

The loop segment comprising residues 70–84 in mitochondrial cytochrome c serves to direct the polypeptide backbone to permit the functionally required heme Fe – S (Met-80) co-ordination. The primary sequence here is highly conserved, which is something rarely observed in surface loop segments and suggests that its purpose is more complex than its obvious structural role. The β-II turn formed by Pro-76 and Gly-77 is postulated to be key to the redirection of the peptide backbone required to execute the loop. We assessed the importance of Pro-76 and Gly-77 by mutating 1 or both of these residues to alanine such that the range of allowable dihedral angles was altered, and this resulted in significant changes in physicochemical properties and biological activities. We observed structural perturbations using circular dichroism spectroscopy and thermal denaturation studies. Based on these changes, we propose that the Pro-76/Gly-77 β-II turn precisely orients the 70s loop, not only to maintain the backbone orientation required for the formation of the axial heme ligand, but also to provide a complementary surface to physiological partners.
