Abstract
Here, we use Raman spectroscopy to investigate temperature-dependent changes in the atomic-scale structure of the zeolitic imidazolate framework ZIF-7 in a CO2 atmosphere and uncover the mechanism of maximal CO2 adsorption at 206 K. At 301 K, the Raman spectra of ZIF-7 at various CO2 gas pressures reveal a narrow-pore (np) to large-pore (lp) phase transition commencing at 0.1 bar as a result of adsorption of CO2, as evident in the appearance of Fermi resonance bands of CO2 at 1272 and 1376 cm-1. Moreover, the Raman inactive bending mode of CO2 becomes active due to geometrical distortion of adsorbed CO2. It further splits into two peaks due to hydrogen bonding interactions between CO2 and the benzene ring of the benzimidazole linker ZIF-7, as supported by our computational studies. In addition, the interaction between CO2 molecules plays a key role. Upon reducing the temperature at 1 bar CO2 gas pressure, ZIF-7 exhibits softening of the imidazole puckering mode and the Fermi resonance CO2 band due to interactions between CO2 and the framework through hydrogen bonding. At 206 K, substantial modification in the lattice mode and disappearance of the Raman inactive CO2 bending mode confirm the changes in the size of the pore cavity through structural rearrangements of CO2.

Abstract
Prostate cancer (PCa) and benign prostate hyperplasia (BPH) are highly prevalent heterogeneous disorders among men. Whereas PCa and BPH underline common pathological features, apoptotic-related genes might be differentially expressed in these diseases. This study was aimed at testing BCL-2 as well as BALR-2 and ZEB2-AS1 apoptosis-related long non-coding RNA (lncRNA) in patients with PCa and BPH. The expression levels of the BCL-2 gene and ZEB2-AS1 lncRNA were upregulated in tumoural tissues in comparison to adjacent non-cancerous tissues (ANCTs) and BPH tissues. In contrast, the expression level of BALR-2 lncRNA was significantly higher in BPH compared with tumoural tissues. Furthermore, while no association was noticed between the relative expression of ZEB2-AS1 and the tumour grade, the relative expression of BCL-2 and BALR-2 is strongly associated with a higher grade of the tumour in PCa samples compared with the ANCTs. The receiver operating characteristic (ROC) curve analysis indicated the highest specificity and diagnostic value in distinguishing PCa and ANCTs as well as PCa and BPH, respectively. In conclusion, altered expression of BCL-2 and BALR-2 was observed to be associated with tumoural progression and could be used as potential candidates for distinguishing PCa tissues from ANCTs or BPH samples.

Abstract
PURPOSE Intravesical BCG (Bacillus Calmette-Guérin) therapy is indicated as an effective treatment for patients with non-muscle-invasive bladder cancer, despite associate with the side effects. In this study, the incidence of BCG therapy adverse effects was compared among three groups of patients who received celecoxib, phenazopyridine, and oxybutynin with placebo. MATERIALS AND METHODS The randomized controlled clinical trial was conducted on four groups using the parallel group method. A checklist is used for weekly assessment of urinary symptoms, systemic symptoms of BCG therapy, and adverse drug reactions. RESULTS The study included 120 patients, 10 female and 110 male. The mean age 59.65 ± 6.2 years. The results of multivariate analysis show that there is a significant decrease in urinary frequency for patients who received phenazopyridine (95% CI: 0.09, 0.31, OR = 0.17, P <.001) and also celecoxib group (95% CI: 0.10, 0.43, OR = 0.21, P <.001) compared to those in placebo group. Patients in celecoxib group (95% CI: 0.02, 0.07 ,OR = 0.04, P <.001), phenazopyridine (95% CI : 0.07, 0.37,OR=0.16, P <.001) and oxybutynin (95% CI: 0.02, 0.12,OR = 0.05, P <.001) were less likely to have urgency than those in placebo. Moreover, significant decrease was found for dysuria in the three treatment groups in comparison with placebo group. CONCLUSION According to the results, celecoxib, phenazopyridine and oxybutynin can effectively decrease the side effects of BCG immunotherapy compared to placebo. Among these three treatments, the most effective and safest treatment option is celecoxib.

Abstract
PURPOSE Many attempts are being made to find an association between varicocele characteristics and sperm parameters. In this study, we investigated the association between a newly introduced varicocele reflux grading pattern and sperm parameters, as well as its effect on spermogram improvement after varicocelectomy. METHODS In a prospective study, 73 patients with a clinical single-sided varicocele who underwent corrective varicocelectomy were included. Reflux pattern was determined on Color Doppler Ultrasound (CDUS) and categorized into four grades: grade 1 (retrograde), grade 2 (augmentation), grade 3 (enhancement), and grade 4 (stasis). The association of pre- and postoperative spermogram with the patients' reflux pattern was evaluated. RESULTS A significant positive association was found between the venous diameter and reflux pattern. Higher grades of the reflux pattern were associated with the more severe hemodynamic pattern of the reflux (shunt type). A significant association was found between the reflux pattern and preoperative semen characteristics, and this association was more prominent in constant venous diameter. In this respect, the enhancing reflux type was associated with the most impaired preoperative sperm count, motility, and morphology. The enhancing type also revealed the most improvement in spermogram after varicocelectomy. CONCLUSION Patients with a higher reflex grade, particularly enhancing pattern, will most benefit from the surgical correction of varicocele. These findings suggest reflux pattern as a promising prognostic factor for a favorable outcome after varicocelectomy.

Abstract
Background: Needle biopsy of the prostate is a diagnostic method for prostate cancer which is a relatively safe method with low risk of serious complications. The evidences regarding the occurrence of erectile dysfunction following prostate biopsy are controversial. Herein, we aimed at determining the rate of erectile dysfunction in those undergoing transrectal ultrasound-guided prostate biopsy. Method: All candidates for prostate biopsy were enrolled. The International Index of Erectile Function-5 was completed 1 m before and 1, 3, and 6 months after ultrasound-guided prostate biopsy by each patient for erectile dysfunction. Patients with a previous history of erectile dysfunction which due to a positive pathology had received any type of treatment were excluded from the study. Results: Eighty patients with the mean age of 64.8 years, the mean prostate-specific antigen level of 11.64 ng/dL, and the mean prostate volume of 62.43 cc were included. The prostate biopsy result was positive in 38.8% of the cases. No significant relationship was found between erectile dysfunction and prostate-specific antigen level, prostate volume, and the pathology result (P = 0.320, 0.509, and 0.131). The mean questionnaire score 1 month before and after the biopsy was 23 and 18, respectively; it demonstrated a significant difference (P < 0.001). The same score was 17 and 14.5 three and six months after biopsy. The mean score 1 m before and 3 m after biopsy also revealed a significant difference (P < 0.001). Conclusion: Transrectal ultrasound-guided needle biopsy of the prostate causes progressive erectile dysfunction in these patients. This relationship is not affected by the biopsy result, prostate volume, or the prostate-specific antigen level.

Abstract
BACKGROUND: It is apparent that prostate cancer has harmful effects on the erythrocytes, leucocytes, and platelets. In addition, it has been suggested that the toxic granules in neutrophils lead to inflammation in the cancerous tissues besides the activation of monocytes, so in this study we aimed to evaluate the blood neutrophil count besides the neutrophil-to-lymphocyte ratio as a predictive factor for prostate biopsy results and their relationship with prostate cancer grade in patients undergoing biopsy of the prostate. METHODS: For all men with irritative lower urinary tract symptoms visiting Hasheminezhad Hospital from January to July 2015, in case of having a suspicious digital rectal examination or aged above 40 years, prostate-specific antigen was requested and in case of abnormal results, they underwent prostate biopsy. In order to examine the study hypothesis, the blood neutrophil count and the neutrophil-to-lymphocyte ratio were measured and compared with the abnormal prostate-specific antigen results and suspicious digital rectal examination. RESULTS: Among the 500 referred samples for biopsy, 352 (70.4%) had a negative biopsy result, while it was positive in the other 148 (29.6). The mean neutrophil count showed no statistical difference regarding the biopsy results (p = 0.381). When measuring the neutrophil-to-lymphocyte ratio again with biopsy results, no statistically significant difference was obtained based on the biopsy results (p = 0.112). CONCLUSION: Neutrophil count and neutrophil-to-lymphocyte ratio cannot be predictive factors for positive prostate cancer biopsy.

Abstract
Burns are calamities with considerable morbidity and mortality rates. We attempted to examine the epidemiology of burns in Zanjan city, in northwest Iran, by a systematic study of existing information. The medical files of 2,590 thermal burn patients treated in our hospital in Zanjan city, Iran, from December 2010 to November 2016 were studied. Patient information, including age, sex, burn degree, season, cause of burn, hospital stay and treatment results were analyzed. About 65% of the patients were male (n=1691). Most burns (92.8%) were less than 30% total body surface area. Mean age and hospital stay were 25.4 years old and 9.1 days, respectively. The most common causes of burn were hot liquids, gas explosion and fire, respectively. Except for self-immolation, which was more common among men, there was no significant relationship between cause of burn and the studied variables. The six-year mortality rate was 2.9%, and was more common in the years 2011 to 2013. In addition, distribution of causes of burn had a significant trend (variation). Fire burn had a decreasing trend and gas and chemical burn had increasing trends in this period. In northwest Iran the causes of burn changed over the six years. Chemical burns, gas explosion burns and burn mortality increased. Some of these results were due to economic and pharmaceutical sanctions in Iran. Because of Iran's industrial development, it is recommended that preventive measures for chemical, gas and electrical burns be conducted.

Abstract
Emerging studies have been shown that the expression of micrRNA-146a (miR-146a, as a regulator of nuclear factor κB (NF-κB)), is changed in diabetic patients and animals. This study was designed to evaluate the possible role of miR-146a in the pathogenesis of diabetes-related microvascular complications. Concurrent with the creation of cellular hyperglycemia (25 mmol/L for 24 h), human umbilical vein endothelial cells (HUVECs) were transfected with 20 nmol/L of hsa-miR-146a antagomir or scramble using HiPerFect reagent (Qiagen). D-mannitol was used as osmotic control. Hyperglycemia increased the NF-κB gene expression and protein activity (as an inflammation index) in cultured HUVECs. Moreover, the gene expression level of miR-146a, and its target proteins, tumor necrosis factor receptor-associated factor 6 (TRAF6) and interleukin-1 receptor-associated kinase 1 (IRAK1) were increased under hyperglycemic condition. The knockdown of miR-146a by transfection of miR-146a antagomir notably increased the NF-κB activity and decreased the NF-κB mRNA in hyperglycemic HUVECs. Furthermore, miR-146a antagomir significantly increased IRAK1 and TRAF6 mRNA levels under hyperglycemic condition. These results demonstrate that the expression of miR-146a is upregulated in HUVECs during early phase of hyperglycemic condition possibly to regulate the NF-κB activity through inhibition of IRAK1 and TRAF6 (Fig. 4, Ref. 32).

Abstract
LiZr2(PO4)3 (LZP) belongs to the NASICON family of compounds whose ionic conductivity can be tuned by substitution of different cations or by increasing the temperature or pressure. Besides its conductivity, thermal and electrochemical stability makes it useful as a cathode material for lithium-ion energy storage devices. Temperature dependent Raman spectroscopic studies were carried out on the monoclinic (β') phase of LZP in the temperature range 298-853 K. A reversible structural phase transition driven by disorder in lithium sites is observed at 603 K. The spectral data enable an understanding of dynamics of the mobile Li ion and PO4 internal modes across the orthorhombic structural phase transition. On the basis of these studies, a reported change in the conductivity around 600 K is explained. High pressure Raman spectroscopic measurements on β'-LiZr2(PO4)3 reveal the onset of a structural phase transformation at 3.8 GPa and amorphization above 10 GPa. On decompression from 26 GPa, the amorphous phase remains unchanged, indicating irreversible nature of pressure-induced amorphization. Three low frequency Raman modes at 100, 124, and 144 cm(-1), which soften with an increase in pressure could be the driving force for the phase transition at 3.8 GPa. Pressure-induced phase transition prior to amorphization in β'-LiZr2(PO4)3 could be due to collapse of Zr-O-P bond angles. Pressure-induced amorphization in this compound might be due to kinetic hindrance of equilibrium decomposition.

Abstract
AZr2(PO4)3 (A=Na, K, Rb, Cs) are a set of framework structured compounds that exhibit tunable ultralow thermal expansion over the wide temperature range of 293-1273K. We report a systematic Raman spectroscopic investigation on AZr2(PO4)3 (A=K, Rb and Cs) compounds as a function of temperature in the range 80-860K and pressures of up to 32GPa. To get insight into the thermal expansion property, phonon anharmonicity has been investigated by studying the temperature and pressure dependence of Raman peak shifts and line widths and computed bulk modulus. We have compared the phase transition and amorphization pressures of the various members of AZr2(PO4)3 to account for the stability of the ambient rhombohedral phase. We find that unlike most of the anomalous thermal expansion materials, in AZr2(PO4)3 (A=K, Rb and Cs), the phonons that are anharmonic with temperature do not necessarily exhibit anharmonicity with pressure.

Abstract
Although obesity has been associated with improved survival on dialysis, its short-and long-term effects on renal transplantation outcomes remain unclear. Herein, we evaluate the short-term and intermediate long-term effects of obesity on first-time renal transplant patients. A retrospective analysis was performed on 180 consecutive renal transplant recipients from living unrelated donors during 2006-2008 in a major transplantation center in Tehran, Iran. Among these, 34 (18%) patients were found to be obese (body mass index ≥30 kg/m 2 ). Obese patients were more likely to develop post-transplant renal artery stenosis (RAS) (17.6% vs. 2.8%, P <0.001), hematoma (47.9% vs. 17.6, P = 0.009), surgical wound complications (64.7% vs. 9.6%, P <0.001) and renal vein thrombosis (2% vs. 0%, P <0.001). However, the incidence of delayed graft function, lymphocele, urologic complications of ureterovesical junction stenosis or urinary leakage, surgical complications of excessive bleeding or renal artery thrombosis and duration of hospitalization were similar between the two groups. The two-year patient and graft survival were also statistically not different. Renal transplantation in obese recipients is associated with a higher incidence of post-transplant RAS, hematoma, surgical wound complications and renal vein thrombosis, but similar two-year patient and graft survival.

Abstract
BACKGROUND Human immunodeficiency virus (HIV) is a public health challenge facing both developing and developed nations. Although injecting drug use is even the main route of HIV transmission in Iran, sexual route is rising gradually. Vulnerable women have been considered as important bridging population for driving HIV epidemics. To increase the access to vulnerable women, in 2007, 5 pilot centers were established in risky areas to deliver comprehensive services to women who themselves or their spouses are engaged in drug use, risky sexual behavior or have history of imprisonment. Management of Sexually Transmitted Infection, psychological counseling and harm reduction are provided by female staff. The aim of this study was to report the activities conducting in 2008. METHODS Registered information was used to assess the demographic characteristic, HIV/ AIDS related risk factors and services delivered to clients. RESULTS Till March 2008, 442 clients have been admitted. Most of them (36.2%) had 25-34 years old. 14.3% were illiterate and 31% were totally jobless. The most prevalent risk factors were risky sexual behavior (27.1%) and non-injecting drug use (23.2%). Injecting drug use was detected in 11.3% of attendees. Dividing clients according to marital status, risky sexual behavior was the main risk factor in unmarried (40.2%) and divorced (26.9%) but in married and widow ones, non-injecting drug use was the most (25.8% and 36.5% respectively). Harm reduction (40.5%) and counseling (36.6%) were the most delivered services. CONCLUSION Since vulnerable women play a critical role to spread HIV-epidemic to general population, increasing centers provide more access to this population.

Abstract
BACKGROUND In the previous studies, the rate of primary infertility was reported differently. It seems the main reasons are related to the different methods of data collection and information analysis. Therefore, introducing a precise method to determine the infertile couples and the population exposed to the risk of infertility is an important issue to study primary infertility. METHODS The proposed methodology for assessing primary infertility rate has been designed and applied by Avicenna Research Institute in a national survey. Sampling was conducted based on probability proportional to size cluster method. In this survey, after reviewing the former studies, the reproductive history was used as a basis for data collection. Every reproductive event was recorded with a code and a date in the questionnaire. To introduce a precise method, all possible events were considered thoroughly and for each situation, it was determined whether these cases should be considered in numerator, denominator or it should be eliminated from the study. Also in some situations where the correct diagnosis of infertility was not possible, a sensitivity analysis was recommended to see the variability of results under different scenarios. CONCLUSION The proposed methodology can precisely define the infertile women and the population exposed to the risk of infertility. So, this method is more accurate than other available data collection strategies. To avoid bias and make a consistent methodology, using this method is recommended in future prevalence studies.

Abstract
Allograft with multiple renal arteries (MRA) is considered to have an increased post-transplantation risk due to vascular and urologic complications. The aim of this study is to investigate the outcome of living donor kidney transplantation using allograft with a single artery and recipients of allografts with multiple arteries. Seven hundred and eighteen consecutive adult kidney transplants done between 1998 and 2007, with living unrelated kidney donors, were enrolled in this retrospective analysis. Data from the group with MRA (n = 60) were compared with those from the group with single renal artery (SRA) (n = 658). Delayed graft function (DGF) was more frequent in recipients' allografts with more than 2 arteries when compared with SRA recipients (Odds Ratio: 1.2; 95% CI:1.08-1.9, P = 0.02), but there was no difference between SRA and allograft with two arteries. The incidence of acute rejection (AR) was not statistically greater in recipients with MRA. Renal artery stenosis (RAS) occurred more frequently in patients with MRA (8.3% vs. 5.9% and P = 0.02), but other vascular complications such as renal artery thrombosis and hematoma revealed no differences (P > 0.05). Urologic complications such as UVJ obstruction, urinary leakage and ureteropelvic obstruction were not statistically different between the groups. The actuarial 1-year allograft survival rate was comparable in both groups (93.6% vs 96.8%, P = 0.22). Allografts with more than two arteries were associated with increased DGF and RAS, but no surgical or urological complications were detected in our series. Our findings demonstrate that renal allograft transplantation with multiple arteries could be performed with reasonable complications and acceptable outcomes.

Abstract
Different cancer treatments such as chemotherapy and radiotherapy can lead to azoospermia and even sterility for an unknown period. Whether the type of cancer could affect semen quality or not is under debate. In this study, we have reviewed semen parameters of men with cancer who deposited their sperm samples at the Avicenna Research Institute tissue bank before undergoing cytotoxic treatment. This descriptive retrospective study examined 73 cases referred to sperm bank, because of malignancy, prior to initiation of cancer treatments including chemotherapy and radiotherapy. The data recorded were age, marital status, reproductive history, semen analysis reports and cancer history of the patients. Semen samples were analysed according to recommendations of the World Health Organization (1999) before freezing. Results of the analysis showed that 71.2% (52) of patients had oligozoospermia, 93.2% (68) teratozoospermia and 86.3% (63) asthenozoospermia. Different groups of cancer patients did not show any differences in oligozoospermia, teratozoospermia and asthenozoospermia. Impaired spermatogenesis even prior to cancer treatment indicates the importance of fertility preservation. As the majority of patients had suitable specimens for freezing and assisted reproduction, sperm banking is recommended to be performed promptly and before any treatment, especially surgery.

Abstract
BACKGROUND Apolipoprotein E (APOE), which its ε4 allele has been reported as a risk factor in late onset Alzheimer's disease (AD), is the main cholesterol carrier in the brain. ATP-binding cassette transporter A1 (ABCA1) gene on chromosome 9, which has been known by genome-wide AD linkage study, has an important role in cellular cholesterol efflux. This study determines the association between sporadic AD and the human ABCA1 and APOE gene polymorphisms in Iranian population. METHODS 154 AD cases and 162 control subjects from Iranian population were genotyped for APOE genotypes and ABCA1 polymorphism (R219K). RESULTS The frequency of ε2ε3 genotype was higher in control subjects comparing AD patients but was not significant (13% versus 5.8%) and ε3ε4 genotype frequency was significantly higher in AD cases comparing with control subjects. APOE-ε2 allele frequency in cases was lower than control subjects but this difference was not significant (4.5% versus 8%). Individuals carrying ε4 allele, developed AD 6.5 times more than non-carriers (OR=6.52, 95%CI=2.63-16.17). There was no significant association between ABCA1 polymorphism and AD. CONCLUSION Unlike other studies, R219K polymorphism was not dependent on gender and APOE-ε4 allele and there was no association between APOE and ABCA1 in AD patients compared to controls.

Abstract
BACKGROUND Alzheimer's disease as a neurodegenerative disorder is the commonest type of dementia. A growing number of genes have been reported as the risk factors, which increase the susceptibility to Alzheimer's disease. Apolipoprotein E (APOE), which its ε4 allele has been reported as a risk factor in late onset Alzheimer's disease (AD), is the main cholesterol carrier in the brain. The main goal of this study was to assess the role of APOE genotypes and alleles in AD in Iranian population. METHODS This study was performed in Tehran, Iran from 2007 to 2008. Totally, 154 AD cases and 162 control subjects from Iranian population were genotyped for APOE using PCR method. Genotype and alleles frequencies for APOE were calculated and compared between AD case and control subjects by χ2 or Fisher's exact test. Type one error assumed less than 0.05. RESULTS The frequency of ε2ε3 genotype was significantly higher in control subjects than AD patients was (13.5% versus 5.2%, P< 0.05) and ε3ε4 genotype frequency was significantly higher in AD cases compared with control subjects. APOE -ε2 allele frequency in cases was lower than that of control subjects but this difference was not significant (4.2% versus 7.7%). CONCLUSION It seems that individuals carrying ε4 allele, develop AD 6.5 times more than non-carriers do (OR= 6.566, 95% CI= 2.89-14.92). It has been reported that ε4 allele acts in dose- age-dependent manner but we have shown that the risk of developing AD in male APOE -ε4 allele carriers is higher than that of female ε4 carriers.

Abstract
Aberrant expression of the caveolin-1 (CAV1) gene is associated with Alzheimer's disease (AD) brain. We have recently reported a polymorphic purine stretch located at between 1.8 and 1.5 kb flanking the CAV1 gene, whose alleles and genotypes are associated with late-onset AD. Extra-short homozygote haplotypes were observed that were present only in the AD cases. Following an independent case/control study, we report alleles at the other extreme of the allele range, haplotypes of which were observed to be homozygous across the region in the AD cases. We propose that there is a window for the length of motifs and haplotypes in the controls. Homozygosity for shorter and longer motifs and haplotypes was linked with AD in our study. Our findings elucidate novel predisposing haplotypes at the CAV1 gene purine complex, and confirm the role of this region in the etiopathophysiology of late-onset AD.

Abstract
BACKGROUND Recent results have indicated that high prerenal and postrenal transplant soluble CD30 levels may be associated with an increased acute rejection and graft loss. The aim of this study was to evaluate the feasibility of using serum sCD30 as a marker for predicting acute graft rejection. MATERIALS AND METHODS In this prospective study,we analyzed clinical data of 80 patients, whose pretransplant and posttransplant serum levels of sCD30 were detected by enzyme-linked immunoassay. Eight patients developed acute rejection, 7 patients showed delayed graft function, and 65 recipients experienced an uncomplicated course group. The patients were followed for 12 months, and there were no deaths. RESULTS Preoperative sCD30 levels of 3 groups were 96.2 -/+ 32.5, 80.2 -/+ 28.3, and 76.8 -/+ 29.8 U/mL (P = .28). After transplant, a significant decrease in the sCD30 level was detected in 3 groups on day 14 posttransplant (P < .001), while sCD30 levels of acute rejection group remained significantly higher than delayed graft function and nonrejecting patients (28.3 -/+ 5.2, 22.1 -/+ 3.2, and 19.8 -/+ 4.7 U/mL) (P = .02). Positive panel reactive antibody was not statistically different among groups (P = .05). Also, hemodialysis did not affect sCD30 levels (P = .05). Receiver operating characteristic curve demonstrated that the sCD30 level on day 14 posttransplant could discriminate patients who subsequently suffered acute allograft rejection (area under receiver operating characteristic curve, 0.95). According to receiver operating characteristic curve, 20 U/mL may be the optimal operational cutoff level to predict impending graft rejection (specificity 93.8%, sensitivity 83.3%). CONCLUSIONS Measurement of the soluble CD30 level on day 14 after transplant might offer a noninvasive means for recognizing patients at risk of acute graft rejection during the early posttransplant period.

Abstract
Crucial interaction of caveolin-1 (CAV1) with beta- and gamma-secretases, and aberrant expression of the gene encoding this protein in Alzheimer's disease (AD) support a role for CAV1 in the pathophysiology of this disease. We report a novel polymorphic purine complex stretching approximately 150 bp of genomic DNA at the 1.5 kb upstream region of the human CAV1 gene, alleles and genotypes of which are associated with sporadic late-onset AD. Extra-short alleles were observed in the case group that were absent in the control subjects. Remarkably, 63% of these alleles were observed to be homozygous in length, forming 23.7% of the homozygote length compartment in the AD cases (chi(2) = 19.08, df = 1, P < 0.000007). Increased homozygosity for length was also observed at this region in the Alzheimer's cases, for the allele lengths shared by the case and control groups [(chi(2) = 30.75, df = 1, P < 0.0000000, OR = 4.54, CI 95% (2.56-8.3)]. This region contains GGAA and GAAA motifs, the consensus binding sites for the Ets and IRF family transcription factors, respectively, and is highly conserved in distantly related non-human primates in respect with location and motif sequence. The effect of this complex sequence on the expression of CAV1, and the related mechanisms in the pathophysiology of AD remain to be clarified.

Abstract
Life table and temperature-dependent development of Diadegma anurum (Thomson) (Hymenoptera: Ichneumonidae) was studied on diamondback moth, Plutella xylostella L. (Lepidoptera: Plutellidae) reared on cabbage, Brassica oleracea L. variety capitata, and cauliflower, Brassica oleracea L. variety botrytis. The developmental periods of immature stages were recorded at five constant temperatures (15, 20, 25, 30, and 35 degrees C). The population of D. anurum and its host failed to survive at 35 degrees C. Mean total development time of D. anurum was not significantly different on two host plants except at 25 degrees C. The developmental zero (low temperature threshold) was estimated to be 7.0 and 6.9 degrees C, and the thermal constant was 282.3 and 277.7 DD on cabbage and cauliflower, respectively, using the linear model. Data were fitted to four nonlinear temperature-dependent models. Evaluation of the models was carried out based on the following criteria: fit to data, number and biological values of the fitted coefficients, and accuracy on the estimation of the thresholds. Consequently, the Briere-1 model was accepted and recommended for the description of temperature-dependent development of D. anurum. The life table parameters of D. anurum were also studied at 25 degrees C constant temperature. Its intrinsic rate of increase (rm) and mean generation time (T) were estimated to be 0.169 and 16.083 d on cabbage, respectively. The life table parameters of D. anurum can be used to develop the models of population dynamics and prediction.

Abstract
PURPOSE This study was undertaken to evaluate the effects of renal transplantation on serum level of free and total PSA. MATERIALS AND METHODS In this study, we included 30 male patients with a mean age of 46 years with end-stage renal disease undergoing renal transplantation at our department. None of the patients had any history of prostate cancer. All patients had immediate onset of renal function after transplantation, defined by a spontaneous decrease in serum creatinine on postoperative day 1 and a subsequent decrease daily during week 1. Renal transplantation included living-related donors in all patients. Blood samples were obtained before and at posttransplant day 6 before removal of Foley catheter. Measurements of free PSA and total PSA were performed with immunofluorometric assays. Glomerular filtration rates were monitored by analyzing serum creatinine. The significance of changes with time was estimated by the Wilcoxon signed ranks test for paired observations with P<.05 considered statistically significant. RESULTS The mean free and total PSA levels before transplantation were 0.22 (range, 0.0.05 to 0.4) and 1.5 ng/mL (range, 0.1 to 2.9), respectively. There was a significant decrease (30% of original levels) in serum fPSA at posttransplant day 6 (P<.05) in all patients. There was no significant changes of total PSA at posttransplant day 6. CONCLUSIONS These results verify the hypothesis that free PSA is eliminated from the blood circulation by glomerular filtration and severe renal failure influences its levels. Thus, we should consider different cutoffs for free to total ratio before and after renal transplantation.

Abstract
INTRODUCTION Methanol poisoning is an uncommon but potent central nervous system toxin. We describe here the CT and MR findings in nine patients following an outbreak of methanol poisoning. METHODS Five patients with a typical clinical presentation and elevated anion and osmolar gaps underwent conventional brain MRI with a 1.5-T Gyroscan Interna scanner. In addition nonenhanced CT was performed in another three patients with more severe toxicity. RESULTS Bilateral hemorrhagic or nonhemorrhagic necrosis of the putamina, diffuse white matter necrosis, and subarachnoid hemorrhage were among the radiological findings. Various patterns of enhancement of basal ganglial lesions were found including no enhancement, strong enhancement and rim enhancement. CONCLUSION A good knowledge of the radiological findings in methanol poisoning seems to be necessary for radiologists. The present study is unique in that it enables us to include in a single report most of the radiological findings that have been reported previously.

Abstract
BACKGROUND AND OBJECTIVES Failed endotracheal intubation is a principal cause of morbidity and mortality in anesthetized patients. The aim of this study was to investigate the efficiency of lateral neck radiography in predicting difficult intubation. METHODS In a prospective triple-blind study, 100 patients (aged 18-89 yr), scheduled for elective surgery were randomly selected. Lateral neck X-ray was obtained from each of the patients before operation. Several angles and parameters on the X-ray were proposed to illustrate a relationship with easy or difficult intubation. A radiologist recorded these angles before the operation. An anaesthesiologist also determined the Mallampati score preoperation. At the time of intubation, two other anesthesiologists performed a laryngoscopy and, according to established criteria, identified the patients as easy or difficult intubation. The results were then compared with each other. RESULTS Fifteen patients were identified as having difficult intubation (laryngoscopy Grades III and IV). Sensitivity and specificity of the Mallampati Class test were 26% and 100%, respectively. The sensitivity and specificity of the lateral neck X-ray for three measured angles were 100%. The positive and negative predictive values (NPVs) for those angles were 100% and for Mallampati classification were 100% and 80%, respectively. CONCLUSIONS Compared to the Mallampati Class test, our method of analyzing the lateral X-ray, although not as easy and universally applicable as Mallampati Class test, proved to be a suitable method for predicting difficult intubation.

Abstract
Unilateral lesions of rat entorhinal cortex produce a transitory performance deficit on spatial learning tasks, such as reinforced alternation in a T-maze. Tetrahydroaminoacridine (THA), a cholinesterase inhibitor, was administered to determine its effects on behavioral recovery using a reinforced alternation task in a T-maze. Rate of recovery after unilateral entorhinal lesion was not affected by a low dose of THA (0.05 mg/kg), while a higher dose (5.0 mg/kg) impaired recovery. Behavioral recovery was subsequently evaluated in the same rats following lesions to the contralateral entorhinal cortex. Serial bilateral lesions of the entorhinal cortex are known to produce a prolonged performance deficit on the alternation task. The 0.05 mg/kg THA group exhibited an intermediate rate of recovery, between the undamaged control group and bilateral lesion-saline injected groups. The group receiving 5.0 mg/kg of THA after bilateral lesion did not differ from the bilateral lesion-saline group. The failure of THA to significantly improve functional recovery in rats with lesions of the entorhinal cortex indicates that the compound may have limited applicability in treating human neurodegenerative disorders such as Alzheimer's disease.

Abstract
A hierarchical cluster analysis was performed on 273 self-admitted high-school drug users' descriptions of how frequently they had employed marijuana, stimulants, depressants, hallucinogens, solvents, and opiates during the preceding year. Four types of polydrug users were identified and considered as representing an ordinal scaling of the students along a continuum of overall involvement with drugs, and each user was assigned an index score based on his typal membership. A stepwise multiple regression was then performed to discover which of the students' background characteristics and attitudes were related to their polydrug involvement scores. The search for pleasant sensations, the desire for expanded creativity, and the belief that one would cease taking drugs if they were conclusively shown to be harmful were more powerful predictors of polydrug involvement than any of the sociocultural factors.
