Abstract
OBJECTIVE In previous studies, we have shown a three to four times higher urban incidence of breast cancer and estrogen receptor-positive breast cancers in the Gharbiah Province of Egypt. We investigated the urban-rural incidence differences of gynaecologic malignancies (uterine, ovarian and cervical cancers) to explore if they show the same trend that we found for breast cancer. DESIGN Cancer registry-based incidence comparison. SETTING Gharbiah population-based cancer registry (GPCR), Tanta, Egypt. SAMPLE All patients with uterine, ovarian and cervical cancer in GPCR from 1999 to 2002. METHODS We calculated uterine, ovarian and cervical cancer incidence from 1999 to 2002. For each of the three cancers, we calculated the overall and age-specific rates for the province as a whole, and by urban-rural status, as well as for the eight districts of the province. RESULTS Incidence of all three cancer sites was higher in urban than in rural areas. Uterine cancer showed the highest urban-rural incidence rate ratio (IRR = 6.07, 95% CI = 4.17, 8.85). Uterine cancer also showed the highest urban incidence in the oldest age group (70+ age category, IRR = 14.39, 95% CI = 4.24, 48.87) and in developed districts (Tanta, IRR = 4.14, 95% CI = 0.41, 42.04). Incidence rates by groups of cancer sites showed an increasing gradient of urban incidence for cancers related to hormonal aetiology, mainly of the breast and uterus (IRR = 4.96, 95% CI = 2.86, 8.61). CONCLUSIONS The higher urban incidence of uterine cancer, coupled with our previous findings of higher incidence of breast cancer and estrogen receptor positive breast cancer in urban areas in this region, may be suggestive of possible higher exposure to environmental estrogenic compounds, such as xenoestrogens, in urban areas.

Abstract
Abstract
Background: About 40% of aromatase inhibitor (AI)-treated women develop AI-associated musculoskeletal symptoms (AIMSS) such as arthralgias, but the etiology is unclear. Tendon sheath fluid and tenosynovial changes have been demonstrated by imaging in symptomatic AI-treated patients. It is unclear if these changes correlate with development of AIMSS.Methods: Thirty consecutive patients (pts) initiating therapy with letrozole or exemestane on a prospective clinical trial were enrolled to this substudy. Pts with prior wrist trauma or who declined to provide informed consent were excluded. Pts underwent high resolution ultrasonography (US) of the wrists bilaterally and completed the Health Assessment Questionnaire (HAQ), pain Visual Analog Scale (VAS), and Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire at baseline (BL) and after 3 mo of AI. AIMSS was defined as increase in HAQ or pain VAS score during AI therapy that exceeded a predefined cutoff. Analysis of US images was performed in a blinded manner. Imaging abnormalities included the following: presence of fluid, synovitis, and/or hyperemia in the tendon sheath or joint recess. Statistical analysis was performed using univariate chi-square tests and logistic regression analyses.Results: Of the 30 enrolled subjects, 25 completed both BL and 3 mo assessments. Eight of 30 (27%) discontinued therapy because of AIMSS (2 before and 6 after the 3 mo timepoint), and 3 patients discontinued therapy for unrelated reasons. All patients have been followed for at least 6 mo. We observed a significant association between early treatment discontinuation and change in HAQ (Odds Ratio (OR) 1.525, p=0.0006) and VAS (OR 1.307, p=0.0096) but not DASH (OR 1.001, p=0.96) scores between BL and 3 mo. The proportion of pts with abnormalities on US at BL or that developed during therapy is given in tables 1 and 2, respectively. We did not observe a statistically significant correlation between objective abnormalities on US at BL or following initiation of AI therapy and the development of AIMSS or early treatment discontinuation because of AIMSS.Conclusions: Clinically relevant musculoskeletal symptoms develop in AI-treated women, leading to treatment discontinuation in a substantial percentage. However, patient-reported symptoms were not associated with inflammatory changes visible on wrist US in this pilot study.Proportion of pts with US abnormalities at BL # with abnl/total ptsof pts with AIMSS, # with US abnlof pts without AIMSS, # with US abnlof pts who d/c AI b/c AIMSS, # with US abnlof pts who continued AI, # with US abnlAny anatomic site27/30 (90%)9/10 (90%)18/20 (90%)7/8 (88%)20/22 (91%)--Tendon sheath14/30 (47%)7/10 (70%)7/20 (35%)5/8 (63%)9/22 (41%)--Joint recess24/30 (80%)6/10 (60%)18/20 (90%)6/8 (75%)18/22 (82%) Proportion of pts who developed new abnormalities on US during AI therapy # with abnl/total ptsof pts with AIMSS, # with US abnlof pts without AIMSS, # with US abnlof pts who d/c AI, # with US abnlof pts who continued AI, # with US abnlAny anatomic site13/25 (52%)5/9 (56%)7/16 (44%)4/6 (67%)7/19 (37%)--Tendon sheath5/25 (20%)2/9 (22%)3/16 (19%)0/6 (0%)5/19 (26%)--Joint recess12/25 (48%)5/9 (56%)6/16 (38%)4/6 (67%)6/19 (32%)

Abstract
Earlier we have shown that exogenous expression of HIPPI, a molecular partner of Huntingtin interacting protein HIP-1, induces apoptosis and increases expression of caspases-1, -8 and -10 in HeLa and Neuro2A cells. The C-terminal pseudo death effector domain of HIPPI (pDED-HIPPI) specifically interacts with the putative promoter sequences of these genes. In the present manuscript, we predict from structural modeling of pDED-HIPPI that R393 of HIPPI is important for such interaction. R393E mutation in pDED-HIPPI decreases the interaction with the putative promoter of caspase-1 in cells. Expression of caspase-1 is decreased in cells expressing mutant pDED-HIPPI in comparison to that observed in cells expressing wild type pDED-HIPPI. Using HIP-1 knocked down cells as well as over expressing HIP-1 with mutation at its nuclear localization signal and other deletion mutations, we demonstrate that translocation of HIPPI to the nucleus is mediated by HIP-1 for the increased expression of caspase-1. HIPPI-HIP-1 heterodimer is detected in cytoplasm as well as in the nucleus and is associated with transcription complex in cells. Taking together, we are able to show the importance of R393 of HIPPI and the role of HIPPI-HIP-1 heterodimer in the transcription regulation of caspase-1.

Abstract
AIMS/HYPOTHESIS Isolated pure human beta cells would be helpful for a number of research purposes. However, lack of beta cell-specific surface antigens has been a major problem. We aimed to develop a simple method for human beta cell isolation based on the initial elimination of ductal cells by their expression of carbohydrate antigen 19-9 (CA19-9), followed by positive selection of beta cells by their expression of polysialic acid-neural cell adhesion molecule (PSA-NCAM). METHODS Cell type-specific expression of CA19-9, NCAM and PSA-NCAM was studied in sections of adult human pancreas and in cultured primary endocrine and exocrine cells. Dispersed human islet cells were purified in two steps, after 4 days of suspension culture, by binding to magnetic microbeads coupled to antibodies against CA19-9 and PSA-NCAM. RESULTS NCAM expression was detected in ducts and islets in the human pancreas. In contrast, PSA-NCAM immunoreactivity was detected only in islets. PSA-NCAM staining in dispersed cells revealed that the marker is expressed in all endocrine cell types, but not in duct cells. Purification of dispersed islet cells using PSA-NCAM microbeads alone did not completely eliminate contaminating duct cells. However, elimination of the duct cells by CA19-9 microbeads followed by positive sorting of the PSA-NCAM-positive cells in five consecutive islet preparations resulted in 90 to 98% pure endocrine cells, of which 89 to 97% were beta cells. CONCLUSIONS/INTERPRETATION We describe a simple and reproducible method for purification of viable human pancreatic beta cells devoid of exocrine acini and ducts.

Abstract #3049
Background: Estrogen receptors (ER) and associated factors, including progesterone receptors (PgR), modulate estrogenic effects both in normal tissue and in hormone receptor (HR)-positive breast cancers. ERα expression occurs in the majority of breast cancers, although the level of overexpression varies between tumors. Multiple single nucleotide polymorphisms (SNPs) in the genes that encode ER, termed ESR1 (ERα) and ESR2 (ERβ), have been shown to affect phenotypic outcomes, including breast cancer risk, bone mineral density, hot flashes, and lipid levels. We hypothesized that SNPs in genes that encode ER may affect level of ER overexpression.
 Methods: DNA was extracted from white blood cells from 100 subjects with HR-positive breast cancer enrolled in a tamoxifen observational study. SNPs in ESR1 (XbaI: rs#9340799, PvuII: rs#2234693) and ESR2 (01: rs#1256049; 02: rs#4986938) were determined from germline DNA using TaqMan. ER overexpression in paraffin-embedded formalin-fixed tumor specimens was quantified with immunohistochemistry (IHC) of tumor specimens on slides (Ventana Image Analysis System) and with RT-PCR using the Oncotype DX breast cancer assay (Genomic Health, Inc). Gene expression of other ER-associated genes (PgR, BCL2, and SCUBE2) was determined using RT-PCR (Oncotype DX). Expression of ER and associated genes across ER genotype was performed using the Kruskal-Wallis test. For all analyses, a p value of <0.05 was considered statistically significant.
 Results: ER expression assessed using IHC and RT-PCR was statistically significantly correlated, with a Pearson correlation coefficient of 0.43 (p=0.0006). However, there was no association between the ESR1 or ESR2 genotypes and ER expression assessed by either method. A trend between ESR1 XbaI genotype and PgR expression by RT-PCR was noted (p=0.08 for gene-dose effect). No other associations between ER polymorphisms and expression of ER-related genes were identified.
 Conclusions: SNPs in genes encoding for ER do not appear to be associated with level of ER expression in breast cancer. Differences in ER expression between individual tumors are likely due to mechanisms other than these inherited mutations in the ER genes.

Abstract
Basement membranes (BMs) are an important part of the physiological microenvironment of pancreatic islet cells. In mouse islets, beta-cells interact directly with BMs of capillary endothelial cells. We have shown that in the human islets, the capillaries are surrounded by a double BM both in foetal and adult tissues. The endocrine islet cells are facing a BM that is separate from the endothelia. Laminins are the functionally most important component of BMs. The only laminin isoform present in the human endocrine islet BM is laminin-511 (previously known as laminin 10). The islet cells facing this BM have a strong and polarized expression of Lutheran glycoprotein, which is a well-known receptor for the laminin alpha 5 chain. Dispersed human islet cells adhere to purified human laminin-511 and the binding is equally effectively blocked by a soluble form of Lutheran as by antibody against integrin beta1. Our results reveal unique features of the BM structure of human islets, different from rodents. This information has potentially important implications for the generation of an optimal microenvironment for beta-cell function, proliferation and differentiation.

Abstract
The effect of Mn substitution in Cu ferrite may present a challenge, as there are three transition metals ions distributed among the two available crystallographic sub lattices. This system also presents complicated super exchange interactions. In this study a series of five powdered samples with composition Cu(1-x)Mn(x)Fe2O4 were investigated using XRD and transmission Mössbauer spectroscopy. The variation of lattice parameter, crystallite size, and Mössbauer parameters of the product formed with the variation in the concentration of Mn has been studied. XRD study revealed the formation of pure phase spinels with FCC cubic structure having particle size ranging from 7.2 nm to 20 nm. Lattice constant value showed constant increase with increasing Mn concentration. AFM image confirms the formation of spherical shaped nanoparticles. Mössbauer spectroscopy proves to be an excellent tool for probing the local environment of Fe atoms present in such materials. Results show two sets of six finger patterns for all the samples with two double line pattern obtained for the composition with x = 0.75 and 1.0, indicating the presence of Fe in both A and B site. Increase in Mn concentration first increases the hyperfine field and then it gradually decreases. This effect is observed at both the sites. This effect is due to the relative strengths of Fe-O-X super exchange (X = Fe, Mn, Cu) as well as number of different nearest neighbour of A and B sites. The unexpected behaviour for the last two compositions can be explained by the presence of particle size distribution that results in superparamagnetic behaviour.

Abstract
AIMS/HYPOTHESIS Based on mouse study findings, pancreatic islet cells are supposed to lack basement membrane (BM) and interact directly with vascular endothelial BM. Until now, the BM composition of human islets has remained elusive. METHODS Immunohistochemistry with specific monoclonal and polyclonal antibodies as well as electron microscopy were used to study BM organisation and composition in human adult islets. Isolated islet cells and function-blocking monoclonal antibodies and recombinant soluble Lutheran peptide were further used to study islet cell adhesion to laminin (Lm)-511. Short-term cultures of islets were used to study Lutheran and integrin distribution. RESULTS Immunohistochemistry revealed a unique organisation for human Lm-511/521 as a peri-islet BM, which co-invaginated into islets with vessels, forming an outer endocrine BM of the intra-islet vascular channels, and was distinct from the vascular BM that additionally contained Lm-411/421. These findings were verified by electron microscopy. Lutheran glycoprotein, a receptor for the Lm alpha5 chain, was found prominently on endocrine cells, as identified by immunohistochemistry and RT-PCR, whereas alpha(3) and beta(1) integrins were more diffusely distributed. High Lutheran content was also found on endocrine cell membranes in short-term culture of human islets. The adhesion of dispersed beta cells to Lm-511 was inhibited equally effectively by antibodies to integrin and alpha(3) and beta(1) subunits, and by soluble Lutheran peptide. CONCLUSIONS/INTERPRETATION The present results disclose a hitherto unrecognised BM organisation and adhesion mechanisms in human pancreatic islets as distinct from mouse islets.

Abstract
This case control study was carried out in the department of Biochemistry, Mymensingh Medical College in co-operation with the Pediatric wards of Mymensingh Medical College Hospital and Ganashasthya Nagar Hospital, Dhaka during the period from July 2005 to June 2006. The aim of the study was to explore the status of serum zinc and copper level in Bangladeshi children with Protein Energy Malnutrition (PEM) as a means to monitor the possibility of management of these children as each of these mineral deficiencies produce typical deficiency syndromes. A total of 68 children aging from five months to five years were included in this study. Subjects were divided into two groups-Group I (Control; n=20)-children with normal growth, weight for age between 3rd and 97th centile curve, Centers for Disease Control (CDC) growth chart, USA, 2000 and group II-(children with PEM; n=48)-children with retarded growth, weight for age below 3rd centile of CDC growth chart, USA, 2000. Group II was again divided into three subgroups according to Wellcome classification of PEM and clinical features. These were Group IIA: Marasmus (n=19), Group IIB: Kwashiorkor (n=14) and Group IIC: Marasmic Kwashiorkor (n=15). Serum zinc and copper levels were determined by Atomic Absorption Spectrophotometric method. Statistical analysis was done by using Statistical Package for the Social Sciences (SPSS) window package. Among the different groups of children mean+/-SD (Standard Deviation) of serum zinc in PEM (59.85+/-11.18 microg/dl), Marasmus (66.73+/-8.23 microg/dl), Kwashiorkor (49.69+/-10.35 microg/dl) and Marasmic Kwashiorkor (60.63+/-8.04 microg/dl) were all significantly lower (p<0.001) than in control group (106.16+/-13.36 microg/dl). Similarly mean+/-SD of serum copper in PEM (82.73+/-16.35 microg/dl), Marasmus (93.72+/-9.77 microg/dl), Kwashiorkor (63.75+/-13.12 microg/dl) and Marasmic Kwashiorkor (86.52+/-8.68 microg/dl) were all also significantly lower (p<0.001) than in control group (135.88+/-11.88 microg/dl). It is evident from the study that serum zinc and copper level significantly decrease in children with PEM.

Abstract
BACKGROUND AND PURPOSE The prevalence rate of epilepsy in India ranges between 4.15 and 7.03 per 1000 population. In the developing countries, the major problems of epilepsy are lying in the treatment gap and discontinuation of treatment due to various adverse socio-economic factors. The objective of this study was to evaluate the rate of discontinuation of epilepsy treatment and its related socio-economic factors responsible for discontinuation. MATERIAL AND METHODS Among 1450 patients with epilepsy who were recurrently followed up at an intervals of 2 months from 05 January to 06 January; 620 patients discontinued their treatment. Among them 88.7% patient had breakthrough seizures for more than in two occasions. Socio-economic factors in respect to the treatment were evaluated during the follow-up period vis-a-vis income and expenditure, unemployment status, negative attitude towards medical treatment, non-availability of drugs locally, co-morbid psychiatric and other illnesses, polytherapy and socialillusional thoughts about epilepsy. RESULTS Discontinuation of epilepsy treatment was detected in 42.75% (n = 620) of total patients resulting in recurrence of seizures. Reasons for discontinuation were multiple in most of the cases. The discontinued group had an average annual cost of treatment and income of Rs. 5500 ($110) and Rs. 12,800 ($256), respectively, amounting to 40% of their total income being expended for the cost of the treatment, while in continued group annual cost of treatment and income were Rs. 4500 ($ = 90) and Rs. 24,400 ($ = 580) respectively amounting to only 18% of the total income (p < 0.001) for the cost of treatment. Among the discontinued group, 90% of the patients reported the cost factors, 29.09% due to the unemployment, 20% from the frustration and despair, 20.09% due to non-availability of medicines locally, 17.27% spiritual illusional thoughts about epilepsy, 10% for marital disharmony were the causes for discontinuation of treatment. In the discontinued group, 10% got polytherapy against 9.03% in the continued group (p > 0.01), co-morbid psychiatric illnesses were observed in 4.54% against 3.25% in the continued group (p > 0.10). CONCLUSION The study showed a significant number of patients (42.75%) discontinued epilepsy treatment within 1 year due to poor knowledge regarding the problem of discontinuation, cost and income disparity, unemployment, spiritual illusional thoughts about epilepsy, frustration and mental impairment, lack of uniform availability of drugs in local market. To tide these shortcomings, uniform availability of cheaper antiepileptic drugs with adequate information and communication regarding the disease and upliftment of socio-economic status are to be ensured.

Abstract
To investigate the mechanism of increased expression of caspase-1 caused by exogenous Hippi, observed earlier in HeLa and Neuro2A cells, in this work we identified a specific motif AAAGACATG (- 101 to - 93) at the caspase-1 gene upstream sequence where HIPPI could bind. Various mutations in this specific sequence compromised the interaction, showing the specificity of the interactions. In the luciferase reporter assay, when the reporter gene was driven by caspase-1 gene upstream sequences (- 151 to - 92) with the mutation G to T at position - 98, luciferase activity was decreased significantly in green fluorescent protein-Hippi-expressing HeLa cells in comparison to that obtained with the wild-type caspase-1 gene 60 bp upstream sequence, indicating the biological significance of such binding. It was observed that the C-terminal 'pseudo' death effector domain of HIPPI interacted with the 60 bp (- 151 to - 92) upstream sequence of the caspase-1 gene containing the motif. We further observed that expression of caspase-8 and caspase-10 was increased in green fluorescent protein-Hippi-expressing HeLa cells. In addition, HIPPI interacted in vitro with putative promoter sequences of these genes, containing a similar motif. In summary, we identified a novel function of HIPPI; it binds to specific upstream sequences of the caspase-1, caspase-8 and caspase-10 genes and alters the expression of the genes. This result showed the motif-specific interaction of HIPPI with DNA, and indicates that it could act as transcription regulator.
