Abstract
OBJECTIVES Current methods for periodontal regeneration do not promote collagen fiber insertions into new bone and cementum. We used a pig wound model to screen different functionalized collagen membranes in promoting periodontal reattachment to root surfaces. METHODS Treatment groups included (1) control with no membranes, (2) collagen-coated membranes, (3) membranes with insulin-like growth factor-1 (IGF-1), (4) membranes with amelotin, or (5) membranes attached with calcium phosphate cement (CPC), or with CPC combined with IGF-1. Flap procedures were performed on mandibular and maxillary premolars of each pig. RESULTS Histomorphometric, micro-CT, and clinical measurements obtained at 4 and 12 weeks after surgery showed cementum formation on denuded roots and reformation of alveolar bone, indicating that the pig model can model healing responses in periodontal regeneration. Calcium phosphate cement simplified procedures by eliminating the need for sutures and improved regeneration of alveolar bone (p < 0.05) compared with other treatments. There was a reduction (p < 0.05) of PD only for the IGF group. Large observed variances between treatment groups indicated that a priori power analyses should be conducted to optimize statistical analysis. CONCLUSIONS Pigs can model discrete elements of periodontal healing using collagen-based, functionalized membranes. Screening indicates that membrane anchorage with calcium phosphate cements improve regeneration of alveolar bone.

Abstract
Aim Nano-sized metal particles exhibit special biological, chemical, and physical properties. The aim of this study was to evaluate the effect of incorporating silver nanoparticles into a resin-modified glass ionomer (GI) on its antimicrobial property. Materials and Methods Antibacterial action of GI samples containing 0, 40, 80 ppm silver nanoparticles against standard strains of Streptococcus sanguinis and Streptococcus mutans were assessed by agar diffusion and direct contact tests. Data were analyzed using analysis of variance and Duncan test (P < 0.05). Results Agar diffusion test showed no bacterial inhibition zone, but direct contact test exhibited significant antimicrobial activity against S. sanguinis and S. mutans in resin containing 80 ppm of nanosilver. Conclusion Incorporation of a certain amount of silver nanoparticles into GI can increase its antimicrobial activity compared to the original material.

Abstract
SummaryAim: To perform a meta-analysis of published data on the prevalence and risk of malignancy of focal thyroid incidental uptake (FTIs) detected by Fluorine-18-Fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) or PET/CT. Methods: A comprehensive literature search of studies published up to and including December 2012 was performed. Pooled prevalence and malignancy risk of FTIs were calculated, including a sub-analysis for the geographic areas of origin of the studies. Results: 34 studies including 215 057 patients were selected. Pooled prevalence of FTIs was 1.92% (95% confidence interval [95%CI]: 1.87–1.99%). Overall, 1522 FTIs underwent histopathology evaluation. Pooled risk of malignancy was 36.2% (95%CI: 33.8–38.6%), without significant differences among various geographic areas. Conclusions: FTIs are observed in about 2% of 18F-FDG-PET or PET/CT scans and carry a significant risk of malignancy. Therefore, further investigation is warranted whenever FTIs are detected by 18F-FDG-PET or PET/CT.

Abstract
Previous research on the equine major histocompatibility complex (MHC) demonstrated strong correlations between haplotypes defined by polymorphic intra-MHC microsatellites and haplotypes defined using classical serology. Here, we estimated MHC diversity in a sample of 124 Arabian horses from an endangered strain native to Iran (Persian Asil Arabians), using a validated 10-marker microsatellite panel. In a group of 66 horses related as parent-offspring pairs or half-sibling groups, we defined 51 MHC haplotypes, 49 of which were new. In 47 of the remaining 58 unrelated horses, we could assign one previously identified MHC haplotype, and by default, we gave provisional haplotype status to the remaining constellation of microsatellite alleles. In these horses, we found 21 haplotypes that we had previously defined and 31 provisional haplotypes, two of which had been identified in an earlier study. This gave a total of 78 new MHC haplotypes. The final 11 horses were MHC heterozygotes that we could not phase using information from any of the previously validated or provisional haplotypes. However, we could determine that these horses carried a total of 22 different undefined haplotypes. In the overall population sample, we detected three homozygous horses and one maternally inherited recombinant from 21 informative segregations. Virtually all of the horses tested were MHC heterozygotes, and most unrelated horses (98%) were heterozygous for rare microsatellite-defined haplotypes found less than three times in the sampled horses. This is evidence for a very high level of MHC haplotype variation in the Persian Asil Arabian horse.

Abstract
INTRODUCTION Diabetes mellitus type I is a chronic metabolic disease with an autoimmune origin. The initial manifestations mainly appear during childhood and its prevalence is on the rise in many countries. Some of the complications of diabetes mellitus are problems related to oro-dental structures and periodontal diseases. AIM The present study was undertaken to evaluate the relationship between diabetes mellitus type I and dental and periodontal status in Tehran, Iran. MATERIALS AND METHODS This cross-sectional study was carried out on 50 patients with diabetes mellitus type I who were under treatment in the Diabetic Patients' Center in Tehran and 50 healthy individuals who did not have diabetes, all recruited from schools. The subjects were divided into two age groups of 6-12 and 13-18 years. In test group, HbA1c (glycosylated haemoglobin) level of the patients was collected from the medical records of Association of Diabetic Patients. To make sure that the control subjects did not suffer from diabetes mellitus, their blood glucose was measured with the Glucocard 01 blood glucose monitoring kit (GT-1920, Japan). The periodontal and dental status were assessed using dmft/DMFT (Decayed, Missing, Filled Permanent Teeth), GI (Gingival Index), PPD (Periodontal Pocket Depth), PI (Plaque Index) and CI (Calculus Index). The data obtained from each group were compared statistically using the Mann-Whitney test and Kruskal Wallis Test. RESULTS There was increase in PPD, GI and DMFT values with aging, with no significant differences between the diabetic and non-diabetic groups. PI and DMFT not only increased with aging but also were higher in both age groups in patients with diabetes compared to healthy subjects (p<0.05). GI was higher only in the 13-18 year age group in diabetic patients (p<0.01). There was no relation between the HbA1c (glycosylated haemoglobin) level, and periodontal indices (p<0.09). CONCLUSION It appears that patients with diabetes mellitus type I are more susceptible to periodontal diseases and tooth loss and such problems might be aggravated with aging.

Abstract
OBJECTIVE The Ages and Stages Questionnaires Edition 3 (ASQ-3) are a well-validated international screen for developmental delays in young children. However, previous studies demonstrate variable scores between children eligible to take the same ASQ-3 interval. This study aimed to determine a relationship between age and ASQ-3 score for each screening interval. METHODS This was a baseline exploratory cross-sectional study of infants under 2 years old evaluated for the Peruvian social programme Cuna Más. Participants were included in Cuna Más if they lived in districts with fewer than 2000 inhabitants or 400 homes, indicating a predominantly rural population. The appropriate ASQ-3 screening interval was administered to each subject. Subjects were divided into four 2-week chronological subgroups based on age within each 2-month screening window and aggregated across all 12 screening intervals. Fisher's exact test, analysis of variance and Bonferonni post hoc test were used to compare differences between age subgroups. Linear regression was performed to assess the relationship between ASQ-3 score and both aggregated and disaggregated age subgroup. RESULTS A total of 5850 Peruvian infants were evaluated in 2013. Mean age was 13 ± 6.6 months, 50.7% were male and mean maternal education was 6.6 ± 4.0 years; 34.8% infants were stunted, 7.8% were underweight, 0.9% were wasted and 2% had age adjusted greater than 35 days for prematurity for ASQ-3 interval assignment. Mean total ASQ-3 was 42.2 ± 8.2. The ASQ-3 allocated 49.6% with suspected delay in one or more developmental areas. Before and after adjusting for wealth quintile, maternal education level, infant nutritional status and prematurity adjustment, age subgroup remained significantly associated with total ASQ-3 score (β = 1.8, CI: 1.7-2.0, P < 0.001), sectional ASQ-3 score (all P < 0.001) and inversely associated with one or more scores indicating suspected developmental delay (P < 0.001). CONCLUSIONS The ASQ-3 may underestimate the sensitivity of child development to small differences in age in this population.

Abstract
PURPOSE Bone regeneration is an important concern in periodontal treatment and implant dentistry. Different biomaterials and surgical techniques have been used for this purpose. The aim of the present study was to compare the effect of nanocrystalline hydroxyapatite and human freeze-dried bone graft (FDBG) in regeneration of rabbit calvarium bony defects by histologic and histomorphometric evaluation. METHODS In this experimental study, three similar defects, measuring 8 mm in diameter, were created in the calvaria of 16 white New Zealand rabbits. Two defects were filled with FDBG and nanocrystalline hydroxyapatite silica gel, while the other one remained unfilled to be considered as control. All the defects were covered with collagen membranes. During the healing period, two animals perished; so 14 rabbits were divided into two groups: half of them were euthanized after 6 weeks of healing and the other half after 12 weeks. The specimens were subjected to histologic and histomorphometric examinations for assessment of the following variables: percentage of bone formation and residual graft material, inflammation scores, patterns of bone formation and type of newly formed bone. RESULTS The percentages of new bone formation after 6 weeks were 14.22 ± 7.85, 21.57 ± 6.91, and 20.54 ± 10.07% in FDBG, NanoBone, and control defects. These values were 27.54 ± 20.19, 23.86 ± 6.27, and 26.48 ± 14.18% in 12-week specimens, respectively. No significant differences were found in the amount of bone formation between the groups. With regard to inflammation, the control and NanoBone groups showed significantly less inflammation compared to FDBG at the 6-week healing phase (P = 0.04); this difference was not significant in the 12-week specimens. CONCLUSIONS Based on the results of this experimental study, both NanoBone and FDBG exhibited a similar effect on bone formation.

Abstract
Background: Alveolar ridge preservation could be performed immediately following tooth extraction to limit dimensional changes of alveolar process due to bone resorption. The aim of this study was to compare the clinical and histologic outcomes of socket preservation using two different graft materials; deproteinized bovine bone mineral (DBBM) and demineralized freeze-dried bone allograft (DFDBA) with absorbable collagen membrane. Materials and Methods: Twenty extraction sockets in 20 patients were randomly divided into 2 treatment groups: 10 sockets were augmented with DBBM and collagen membrane whereas 10 sockets were filled with DFDBA and covered by collagen membrane. Primary closure was achieved over extraction sockets by flap advancement. Horizontal and vertical ridge dimensional changes were assessed at baseline and after 4-6 months at the time of implant placement. For histological and histomorphometrical analysis, bone samples were harvested from the augmented sites with trephine during implant surgery. All data were analyzed using SPSS version 18 (α=0.05). Results: Clinical measurements revealed that average horizontal reduction was 2.3 ± 0.64 mm for DFDBA and 2.26 ± 0.51 mm for DBBM. Mean vertical ridge resorption at buccal side was 1.29 ± 0.68 mm for DFDBA and 1.1 ± 0.17 mm for DBBM. Moreover, mean vertical ridge reduction at lingual site was 0.41 ± 0.38 mm and 0.35 ± 0.34 mm for DFDBA and DBBM, respectively. No significant differences were seen between two groups in any of those clinical parameters. Histologic analysis showed statistically significant more new bone deposition for DFDBA compared to DBBM (34.49 ± 3.19 vs. 18.76 ± 3.54) (P < 0.01). Residual graft particles were identified significantly more in DBBM (12.77 ± 1.85) than DFDBA (6.06 ± 1.02). Conclusion: Based on the findings of this study, both materials have positive effect on alveolar ridge preservation after tooth extraction, but there was more new bone formation and less residual graft particles in DFDBA group than in DBBM group.

Abstract
This study evaluated the efficacy of red clover to relieve hot flashes and menopausal symptoms in peri/postmenopausal women. Electronic databases (MEDLINE, Scopus and the Cochrane Library) were searched. The mean frequency of hot flashes in red clover groups was lower compared with that in the control groups (close to statistical significance). Difference in means (MD) of hot flashes frequency was - 1.99 (- 4.12-0.139; p = 0.067; heterogeneity P > 0.01; I(2) = 94.93%; Random effect model). Subjective (vaginal dryness) and objective (maturation value) symptoms of vaginal atrophy showed a significant improvement with 80-mg dose of red clover. Red clover showed less therapeutic effect on psychology status, sexual problems and sleeping disorders. Red clover consumption may decrease frequency of hot flashes, especially in women with severe hot flashes (≥ 5 per day). Red clover may reduce other menopausal symptoms. Further trials are needed to confirm the current systematic review findings.

Abstract
Vaginal atrophy is a common complaint among many women in their menopause, presenting with a cluster of symptoms including dryness, itching, burning/soreness, discharge, irritation and painful intercourse. We searched for existing pertinent data in three chief registries. Specified time brackets included 1996-2013 for Medline, 1990-2013 for Scopus and 2013 for Cochrane Central Register of Controlled Trials (issue 1). Of 110 potentially relevant publications, 17 and 9 trials (7 on maturation value and 2 on vaginal dryness) were selected for qualitative and quantitative analysis, respectively. In general, soy isoflavones seem to improve vaginal symptoms as opposed to control arms. Soy isoflavones were also shown to be more efficacious in quantitative analysis, though this was statistically non-significant. Standardised difference in means of maturation value change was 0.072 (95% confidence interval [CI]: - 0.42 to 0.57), p = 0.777; heterogeneity P = 0.00; I(2) = 85.15%. Difference in means of vaginal dryness was - 0.204 (95% CI: - 0.28 to - 0.126), p < 0.001; heterogeneity P = 0.423; I(2) = 0.00. Soy isoflavones may relieve vaginal symptoms during menopause; nevertheless beneficial effects still remain uncertain due to possible publication bias or vast heterogeneity of the selected studies. Further studies with consistency in design as well as statistics are warranted.

Abstract
OBJECTIVES Implant primary stability is one of the important factors in achieving implant success. The osteotome technique may improve primary stability in patients with poor bone quality. The aim of this study was to compare implant stability using two different techniques namely osteotome versus conventional drilling in the posterior maxilla. MATERIALS AND METHODS In this controlled randomized clinical trial, 54 dental implants were placed in 32 patients; 29 implants were placed in the osteotome group and 25 in the conventional drilling group. Implant stability was assessed at four time intervals namely at baseline, one, two and three months after implant placement using resonance frequency analysis (RFA). RESULTS Primary stability based on implant stability quotient (ISQ) units was 71.4±7 for the osteotome group and 67.4±10 for the control group. There was no statistically significant difference between the two groups in implant stability at any of the measurement times. In each group, changes in implant stability from baseline to one month and also from two months to three months post-operatively were not significant but from one month to two months after implant placement, implant stability showed a significant increase in both groups. CONCLUSION The results of this study revealed that in both techniques, good implant stability was achieved and osteotome technique did not have any advantage compared to conventional drilling in this regard.

Abstract
Current systematic review evaluated the efficacy of topical isoflavones to relieve vaginal symptoms in menopausal women. MEDLINE (1966 to January 2014), Scopus (1990 to January 2014), and the Cochrane Central Register of Controlled Trials (The Cochrane Library issue 1, 2013) were searched using keywords 'isoflavone and vagina'. Relevant studies were reviewed by two independent reviewers. Only randomised controlled trials (RCTs) were included in the systematic review. Out of 115 potentially relevant publications, four studies met the inclusion criteria. Topical isoflavones showed beneficial effects on dyspareunia, vaginal dryness and maturation value. Based on only one trial, the result of conjugated equine oestrogen cream (0.3 mg/day) was similar to use of isoflavone vaginal gel and superior to that of placebo gel. However, drawing any definite conclusion was difficult because of the limited number of RCTs, the small sample sizes, weak methodology and considerable heterogeneity of the included studies.

Abstract
This randomized-controlled trial investigated the effect of physical exercise programme (PEP) on happiness among older adults in Nowshahr, Iran. Results of this study on 120 male and female volunteers showed that an 8-week group physical exercise programme was significantly effective in older adults' happiness. Findings showed that physical exercise programme is so beneficial for increasing older adults' happiness. Physical activity is associated with well-being and happiness. The purpose of this study was to determine the effects of an 8-week long physical exercise programme (PEP) on happiness among older adults in Nowshahr, Iran. This was a randomized control trial study. The participants consisted of a group of 120 male and female volunteers (mean ± SD age: 71 ± 5.86 years) in a convenience sampling among older adults in public parks in Nowshahr, Iran. We randomly allocated them into experimental (n = 60) and control (n = 60) groups. A validated instrument was used to measure well-being and happiness [Oxford Happiness Inventory (OHI)]. Respondents were asked to complete the OHI before and 2 months after implementing PEP. The 8-week PEP was implemented with the intervention group. The statistical analysis of the data was conducted using paired t-test, Fisher's exact test and χ(2). Before the intervention, there was no significant difference in the happiness mean score between the case and control groups; however, after implementing PEP, happiness significantly improved among the experimental group (P = 0.001) and did not improve within the control group (P = 0.79). It can be concluded that PEP had positive effects on happiness among older adults. Planning and implementing of physical activity is so important for older happiness.

Abstract
Background and aims. Diabetic patients display an increased risk of oral disorders, and oral health related quality of life (OHRQL) might affect their management and treatment modalities. The aim of the present study was to determine OHRQL and associated parameters in patients with diabetes. Materials and methods. In this study two hundred patients were recruited from the diabetes clinic in Mustafa Khomeini Hospital in Tehran, Iran. OHRQL was assessed using Oral Health Impact Profile Questionnaire (OHIP-20). Also, another questionnaire was designed which contained questions regarding participants' knowledge about oral complications of diabetes and oral health behavior. OHRQL was categorized as low and good. Data were analyzed using logistic regression at P = 0.05. Results. Of the diabetic patients assessed, 77.5% were in good and 22.5% were in low categories of OHRQL. This quality was significantly associated with age (OR = 4.03, 95% CI = 1.63-11.29), knowledge about diabetes oral complications (OR = 18.17 95% CI = 4.42-158.6), educational level (OR = 26.31 95% CI = 4.2-1080.3), referred for dental visit by physician (OR = 3.16 95% CI = 1.48-6.69), frequency of brushing (OR = 10.29 95% CI = 3.96-31.2) and length of time diagnosed with diabetes (OR = 6.21 95% CI = 2.86-13.63). Conclusion. Oral health related quality of life was not negatively affected by diabetes mellitus in the assessed sample.

Abstract
BACKGROUND We reviewed the available literature on the accuracy of sentinel node mapping in the lymph nodal staging of uterine cervical cancers. METHODS MEDLINE and Scopus were searched by using "sentinel AND (cervix OR cervical)" as key words. Studies evaluating the accuracy of sentinel node mapping in the lymph nodal staging of uterine cervical cancers were included if enough data could be extracted for calculation of detection rate and/or sensitivity. RESULTS Sixty-seven studies were included in the systematic review. Pooled detection rate was 89.2% [95% CI: 86.3-91.6]. Pooled sensitivity was 90% [95% CI: 88-92]. Sentinel node detection rate and sensitivity were related to mapping method (blue dye, radiotracer, or both) and history of pre-operative neoadjuvant chemotherapy. Sensitivity was higher in patients with bilaterally detected pelvic sentinel nodes compared to those with unilateral sentinel nodes. Lymphatic mapping could identify sentinel nodes outside the routine lymphadenectomy limits. CONCLUSION Sentinel node mapping is an accurate method for the assessment of lymph nodal involvement in uterine cervical cancers. Selection of a population with small tumor size and lower stage will ensure the lowest false negative rate. Lymphatic mapping can also detect sentinel nodes outside of routine lymphadenectomy areas providing additional histological information which can improve the staging. Further studies are needed to explore the impact of sentinel node mapping in fertility sparing surgery and in patients with history of neoadjuvant chemotherapy.

PATIENTS, MATERIAL, METHODS A comprehensive literature search of studies published up to February 2014 was performed. Pooled prevalence and malignancy risk of PIU were calculated on a per patient-based analysis including 95% confidence interval (95%CI). Furthermore, we assessed some parameters as potential predictors of malignant PIU. RESULTS Six studies including 47925 patients who underwent 18F-FDG PET/CT were selected. Pooled prevalence of PIU was 1.8% (95%CI: 1.3-2.3%). Overall, 444 patients with PIU were further evaluated and 121 underwent biopsy. The pooled risk of malignancy in patients with PIU further evaluated or verified by biopsy were 17% (95%CI: 12-23%) and 62% (95%CI: 54-71%), respectively. A higher mean age was observed in the group of malignant PIUs compared to benign PIUs. There was a trend towards a higher mean SUV(max) in the group of malignant PIUs but without a statistically significant difference compared to benign PIUs. Peripheric site of PIU but not presence or absence of calcification was a predictor of malignancy. CONCLUSIONS PIU is observed in about 1.8% of 18F-FDG PET/CT scans performed in male patients carrying a significant risk of malignancy. Therefore, whenever a PIU is detected further investigation is warranted to exclude malignancy, in particular when PIU is located in the peripheric site of prostate gland.

Abstract
AIM Suppressive therapy with levothyroxine is the main step in treatment of differentiated thyroid cancer (DTC). However, subclinical hyperthyroidism is associated with deleterious effects on cardiovascular and skeletal systems. Metformin may have a suppressive effect on TSH level. METHODS We performed a single blind randomized controlled trial on the effect of short term Metformin therapy on 50 non-diabetic patients with DTC (mean age of 39.68 ±8.7 years) under suppressive therapy with levothyroxine. Metformin (500 mg) or placebo was added to the drug regimen of the patients and levothyroxine dose decreased by 33%. TSH and thyroid hormone values were measured at the beginning of the study and 3 months after treatment. RESULTS Forty-six patients had papillary and 4 had follicular carcinoma. The mean dose of levothyroxine was 2.2±0.48 µg/kg. The mean TSH level at the beginning of the study was 0.05±.04 mIU/L. The mean age, weight and baseline TSH level was not significantly different between metformin and placebo groups (P>0.2). In the metformin group, the mean (±SD) TSH level was significantly increased from 0.03±0.04 to 3.1±5.7 mIU/L after 3 months of intervention (P=0.01) and the mean thyroid hormone levels were significantly decreased (P<0.001). In the placebo group, the mean TSH level increased from 0.04±0.04 to 3.1±4.7 mIU/L after 3 months (P=0.003). Delta TSH was 3.0±5.6 mIU/L and 3.1±4.7 mIU/L in metformin and placebo groups, respectively (P=0.9). CONCLUSION Adding 500 mg of metformin to drug regimen was not useful to compensate for 33% of levothyroxine dose reduction in patients with DTC.

Abstract
BACKGROUND We evaluated the concordance between peri-areolar blue dye and peri-incisional radiotracer injections for axillary sentinel node mapping of patients with the history of previous breast lesion excisional biopsy. METHODS 80 patients with the history of previous excisional biopsy of the breast lesions were included. All patients received two injections of 99mTc-antimony sulfide colloid in both ends of incision line in an intradermal fashion. 2 mL patient blue V dye was injection to all patients in the peri-areolar area of the index quadrant after induction of anesthesia. All blue or hot nodes were harvested as sentinel lymph nodes. RESULTS At least one sentinel node could be detected during surgery in 79 patients. In total 94 sentinel nodes were detected. All detected sentinel nodes were hot. In three patients sentinel nodes were detected by gamma probe but not blue dye. The tumor location in all of these patients was in the upper lateral quadrant and the incision line was extended into the axillary tail of the breast in all of them. 91 out of 94 sentinel nodes were stained blue, which amounts to 95.8% concordance between blue dye and radiotracer on a per node analysis. CONCLUSIONS Single peri-areolar injection in the index quadrant would suffice for sentinel node mapping of patients with history of excisional biopsy. Care should be taken in patients with large excisional biopsy in the extreme proximity to axilla.

Abstract
PURPOSE Sentinel lymph node biopsy is a fairly new approach for staging of gynecological malignancies. In the current study, the authors comprehensively reviewed the available reports on sentinel node biopsy of endometrial cancer. MATERIALS AND METHODS The authors searched Medline, SCOPUS, ISI web of knowledge, Science Direct, Springer, OVID SP, and Google Scholar with the following search terms: "endometrium OR endometrial OR uterine OR uterus AND sentinel". The outcomes of interest were detection rate and sensitivity. RESULTS Overall, 35 studies had enough information for false negative rate evaluation and 51 studies (including the sub-groups of individual studies) for detection rate evaluation (2,071 patients overall). Pooled detection rate was 77.8% (95% CI: 73.5-81.5%) and pooled sensitivity was 89% (95% CI: 83-93%). Cervical injection, as well as using both blue dye and radiotracer, results in higher detection rate and sensitivity. New techniques such as fluorescent dye injection and robotic-assisted surgery showed high detection rate and sensitivity. CONCLUSION Sentinel node mapping is feasible in endometrial cancer. Using both blue dye and radiotracer and cervical injection of the mapping material can optimize the sensitivity and detection rate of this technique. Larger studies are still needed to evaluate the false negative rate and the factors influencing the sensitivity before considering this method safe.

Abstract
The common pistachio psylla, Agonoscena pistaciae Burckhardt & Lauterer (Hemiptera: Psyllidae), is known as the key pest of pistachio orchards in Iran. This pest passes the winter as adults. In this study, energy allocation changes in relation to ambient temperature were investigated in field-collected adults by measuring total body sugar, trehalose, glucose, sorbitol, myoinositol, glycogen, lipid, and protein contents. Glycogen content decreased with decrease in ambient temperature. The decrease in glycogen content was proportional to the increase in total body sugar, trehalose, myoinositol, and sorbitol contents. In January, with mean ambient temperature of 5.4°C, glycogen content was at the lowest level, whereas total body sugar, trehalose, glucose, and sorbitol were at the highest level. Total body sugar, trehalose, myoinositol, and sorbitol contents increased as temperature decreased from 22.7°C in October to 5.4°C in January. In conclusion, low molecular weight carbohydrates and polyols may play a role in winter survival and adaptation to cold of the common pistachio psylla by providing the required cryoprotection. Also, overwintering adults of the common pistachio psylla may store energy in the form of lipid for later utilization during the overwintering.

Abstract
OBJECTIVE A major controversial issue in the sentinel node biopsy of the breast is the applicability of sentinel node mapping in patients with the history of previous excisional biopsy of the breast lesions. In the current study, we evaluated the reproducibility of lymphoscintigraphy before and after excisional biopsy of the primary breast lesions using superficial peri-areolar injection of the radiotracer. MATERIAL AND METHODS Eighteen patients scheduled for excisional biopsy of breast lesions were included into the study. The patients received intra-dermal injection of the radiotracer in the peri-areolar area of the index quadrant 1 to 2h before surgery. Imaging was performed the day after surgery. Immediately after completion of the first imaging, the patients received another injection of the radiotracer with the same technique, dose, and location. Other sets of lymphoscintigraphy imaging were taken immediately and 4h post second injection. The two sets of lymphoscintigraphy images were compared. RESULTS In 2 patients, sentinel node could not be identified in either set of images. In the remaining 16 patients, one sentinel node was detected in both lymphoscintigraphy image sets. The sentinel nodes of the second image sets were all in the same location of the first sets with at least 5 times higher count. CONCLUSIONS Excisional biopsy of the primary breast lesions does not seem to change the superficial lymphatic drainage pattern from the areola of the breast and sentinel node mapping can be performed after this procedure using superficial periareolar technique.

Abstract
There is an urgent need for new ways to treat Alzheimer’s disease (AD), the most common cause of dementia in the elderly. Current therapies are modestly effective at treating the symptoms, and do not significantly alter the course of the disease. Over the years, a range of epidemiological and experimental studies have demonstrated interactions between diabetes mellitus and AD. As both diseases are leading causes of morbidity and mortality in the elderly and are frequent co-morbid conditions, it has raised the possibility that treating diabetes might be effective in slowing AD. This is currently being attempted with drugs such as the insulin sensitizer rosiglitazone. These two diseases share many clinical and biochemical features, such as elevated oxidative stress, vascular dysfunction, amyloidogenesis and impaired glucose metabolism suggesting common pathogenic mechanisms. The main thrust of this review will be to explore the evidence from a pathological point of view to determine whether diabetes can cause or exacerbate AD. This was supported by a number of animal models of AD that have been shown to have enhanced pathology when diabetic conditions were induced. The one drawback in linking diabetes and insulin to AD has been the postmortem studies of diabetic brains demonstrating that AD pathology was not increased; in fact decreased pathology has often been reported. In addition, diabetes induces its own distinct features of neuropathology different from AD. There are common pathological features to be considered including vascular abnormalities, a major feature arising from diabetes; there is increasing evidence that vascular abnormalities can contribute to AD. The most important common mechanism between insulin-resistant (type II) diabetes and AD could be impaired insulin signaling; a form of toxic amyloid can damage neuronal insulin receptors and affect insulin signaling and cell survival. It has even been suggested that AD could be considered as “type 3 diabetes” since insulin can be produced in brain. Another common feature of diabetes and AD are increased advanced glycation endproduct-modified proteins are found in diabetes and in the AD brain; the receptor for advanced glycation endproducts plays a prominent role in both diseases. In addition, a major role for insulin degrading enzyme in the degradation of Aβ peptide has been identified. Although clinical trials of certain types of diabetic medications for treatment of AD have been conducted, further understanding the common pathological processes of diabetes and AD are needed to determine whether these diseases share common therapeutic targets.

Abstract
AIM Hip prosthesis implantation has witnessed a significant increase in recent years. Despite the advantages of this surgical procedure, it has some complications, the most serious of which is prosthetic infection. This study was conducted to investigate the feasibility of 99mTc-UBI scintigraphy in detection of infectious foci in painful hip prosthesis. UBI (Ubiquicidin 29-41) is an antimicrobial peptide fragment with the ability to target the bacterial colony directly. PATIENTS, METHODS 34 patients, aged 20-79 years, with painful hip prosthesis were included. 99mTc-UBI scan and three phase bone scan were performed and two nuclear medicine specialists interpreted the UBI scans with and without bone scan results at hand. Both qualitative and semi-quantitative methods were used to interpret the 30 minute post injection images. The patients were actively followed up. According to the surgical findings, microbiological culture and active follow up, final diagnosis was made. RESULTS 24 negative and 10 positive UBI scans were recorded. The sensitivity, specificity, negative and positive predictive values and accuracy of the study were all 100%. Bone scan did not have any influence on UBI interpretation. We were able to achieve excellent differentiation between infected and non-infected prostheses with a cut off value of 1.8 for target to non target (T/NT) ratio. No adverse effects were noticed following UBI scan. CONCLUSION Based on the findings, the authors believe that 99mTc-UBI scintigraphy, with its high sensitivity and specificity, provides the physician with an excellent tool for differentiating infection from aseptic loosening of hip prostheses. Using this radiopharmaceutical, it is possible to obtain highly accurate results only 30 minutes after the beginning of the study.

Abstract
Clinical Relevance
Bond strength might improve by delaying the light activation procedure when a cavity conditioner is used for bonding RMGI to enamel. Conversely, delaying the light activation and/or prewarming of RMGI compromises bond strength to dentin and should be avoided.

Abstract
SummaryAim: Sentinel node (SN) biopsy is becoming a standard procedure in the management of several malignancies. Several groups have evaluated the feasibility and value of this procedure in prostate cancer patients. In the current meta-analysis, we comprehensively and quantitatively summarized the results of these studies. Methods: Several databases including Medline, SCOPUS, Google Scholar, Ovid, Springer, and Science direct were systematically searched for the relevant studies regarding SL biopsy in the prostate cancer (“prostate” AND “sentinel” as search keywords). The outcomes of interest were sensitivity and detection rate of the procedure. Results: For detection rate and sensitivity 21 and 16 studies met the criteria of inclusion respectively. Pooled detection rate was 93.8% (95% CI 89–96.6%). Cochrane Q value was 216.077 (I2 = 89.81% and p < 0.001). Pooled sensitivity was 94% (95% CI 91–96%). Cochrane Q value was 14.12 (I2 = 0.0 and p = 0.516). Conclusion: SL biopsy can prevent unnecessary pelvic lymph node dissection in prostate cancer patients. This procedure is feasible with low false negative rate and high detection rate.
