Abstract
This article introduces two transmissive metasurfaces applied to normal windows, aiming to improve the 5G outdoor-to-indoor (O2I) coverage. These windows can be utilized in various settings, such as vehicles or buildings. The proposed unit cells, designed to be wide-incident angle and polarization insensitive, are implemented in both single-glazing and double-glazing glasses, arranged in a periodic structure to form the transmission surfaces. Both metasurfaces maintain optical transparency by incorporating Indium Tin Oxide (ITO) as the conductive element in each unit cell. These engineered transmission surfaces enhance the 5G signal indoor coverage at the 3.5 GHz band across a broad range of incident angles. While multi-layer structures typically exhibit heightened sensitivity to the angle of incidence, the proposed two-layered transmissive surfaces demonstrate substantial angular stability, reaching up to 65 and 75 degrees for double- and single-glazed glass, respectively. To achieve this wide and stable angular response, evolutionary optimization techniques were employed to fine-tune the proposed unit cells. Both designs exhibit a high transmission coefficient across the operating frequency for a variety of incident angles, surpassing those reported in the existing literature. Experimental evaluations of the fabricated prototypes indicate that both metasurfaces hold significant potential for enhancing signal propagation into buildings and vehicles.

Abstract
Line waves (LWs) refer to confined edge modes that propagate along the interface of dual electromagnetic metasurfaces while maintaining mirror reflection symmetries. Previous research has both theoretically and experimentally investigated these waves, revealing their presence in the microwave and terahertz frequency ranges. In addition, a comprehensive exploration has been conducted on the implementation of non-Hermitian LWs by establishing the parity-time symmetry. This study introduces a cutting-edge dual-band line-wave waveguide, enabling the realization of LWs within the terahertz and infrared spectrums. Our work is centered around analyzing the functionalities of existing applications of LWs within a specific field. In addition, a novel non-Hermitian platform is proposed. We address feasible practical implementations of non-Hermitian LWs by placing a graphene-based metasurface on an epsilon-near-zero material. This study delves into the advantages of the proposed framework compared to previously examined structures, involving both analytical and numerical examinations of how these waves propagate and the underlying physical mechanisms.

Abstract
BACKGROUND Renal ischemia-reperfusion (IR) injury is one of the main leading causes of acute kidney injury associated with inflammation, oxidative stress and cell apoptosis. We studied the effects of prazosin, as a specific blocker of α1-AR, on renal IR injury. METHODS Rats were divided into normal control; untreated IR and prazosin-treated IR (1 mg/kg body weight). Prazosin was administered by intraperitoneal injection 30 min prior to IR induction. The level of urea/creatinine and oxidative factors were detected by colorimetric methods. Apoptosis-associated factors, inflammatory, and signaling proteins were analyzed in renal tissue. The abnormalities of renal histopathology were detected by immunohistochemistry. RESULTS Administration of prazosin to IR rats ameliorated serum urea and creatinine and IR-induced histopathological damages. Lipid peroxidation was significantly improved after treatment by prazosin in IR injury rats, however, antioxidant status was not affected. Rats subjected to IR injury activated Bax protein and NF-κB mediated inflammatory response. Moreover, treatment with prazosin inhibited renal NF-κB activation, resulting in a significant decline in pro-inflammatory cytokine of IL-6. CONCLUSION These findings suggest that prazosin could be a good candidate to attenuate renal IR injury due to its ability to modulate renal function, apoptosis and inflammation.

Abstract
INTRODUCTION Achillea tenuifolia Lam (AT) has several biological activities and medicinal properties. In this study, we elucidated the impact of the AT on anxiety-related behaviors, reproductive parameters, antioxidant capacity in male rats subjected to chronic restraint stress (CRS). METHODS 35 Wistar rats were divided into five groups: control, CRS-control (received normal saline) and three CRS-treated groups received AT extract (100, 150, and 200 mg/kg body weight) for 21 consequences days. To induce CRS rats, the rats were immobilized for 21 days and received the extract orally. On the last day of treatment, anxiety-related behaviors were assessed through the sucrose preference test (SPT) as well as elevated plus maze (EPM) tests. Corticosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH), testosterone levels were evaluated to determine reproductive capacity. Sperm parameters including the total count, motility, and viability were also analyzed. Weight of body, testis and seminal vesicles was measured as well. RESULTS The findings revealed that 100, 150, and 200 mg/kg of AT extract had anxiolytic effects in CRS rats, as confirmed by the EPM test and SPT. In addition, AT extract could improve fertile capacity and sperm quality to varying degrees. The level of corticosterone had decreased, whereas the level of LH, FSH and testosterone had increased in CRS-treated rats. Moreover, the reduced level of MDA coincided with an increased rate of antioxidant capacity. Our findings suggest that AT extract could alleviate stress-induced dysfunctions. CONCLUSION Overall, these observations would infer that AT extract could improve fertility capacity and behavioral impairment in the stress conditions. GRAPHICAL ABSTRACT Assumption pathway describing the probability underlying mechanism of CRS-induced anxiety and reproductive toxicity and protective effect of AT.

Abstract
This study aimed to determine the prevalence and early detection of hypodermosis in goats by the investigation of Przhevalskiana larvae and sera collected from the infested animals. This study was conducted in Lorestan province, located in the South-West of Iran, from April 2017 up to April 2018. A total of 3350 goats slaughtered in Lorestan abattoirs were investigated by clinical-parasitological examinations in different periods. The larvae were collected from the back and flank regions of the slaughtered goats. The number of infested animals, gender and age, number of maggots present on the body of each animal, location, and larval stage of warble flies were recorded in this study. To detect an infestation in the early period, a total of 150 blood samples were randomly collected from the field animals in Lorestan, Iran. The morphological findings showed that out of 3350 goats examined, 706 (21.07%) goats were infested. Furthermore, three species of Przhevalskiana, including P. Silenus (n=726, 50.07%), P.crossii (n=440, 30.43%), and P. aegagri (n=284, 19.59%) were recognized as the causative agents of goat hypodermosis in this province. No significant difference was observed between genders and/or among the age groups (P>0.05). The anti-Przhevalskiana antibodies in the serum samples were detected using ELISA from August up to mid-September (summer). Clinical diagnosis of infestation was usually performed from late October until mid-March (winter) by visual observations and direct palpation of warbles in the back and flank regions of the animals. It could be concluded that the use of ELISA can help to detect hypodermosis among goats in the early stages.

Abstract
Goat warble-fly infestation is one of the parasitic diseases caused by the larvae of przhevalskiana spp. It is known to be a major challenge for health and welfare in infested goats and causes high economic losses in livestock worldwide. The detection of goat grub was previously conducted by direct palpation of second and third stage larvae in the back and flank site of the live animals or visual evaluation of the carcasses in slaughterhouses. However, due to the small size of the first instar larvae of przhevalskiana (less than 1 mm during emerging from the egg), some of the infected cases were ignored and recorded as negative samples. Immunodiagnostic procedures as easy and cost-effective diagnostic methods provide early detection of myiasis in living animals (even when the larvae are still migrating or are undetectable in the animal body).This study was conducted to evaluate the competitive enzyme-linked immunosorbent assay (ELISA) system in order to detect the antibodies of przhevalskiana larvae in the goat sera. In order to prepare the larval antigen, 200 first instar larvae of przhevalskiana were collected from the subdermal region of the back and flanks of the infested goats in Khoramabad slaughterhouse, Khoramabad, Iran, from September 2017 to March 2018. Totally, 37 and 46 sera samples were taken from the infected and uninfected goats. The sensitivity and specificity at cut-off 3SD were obtained at 89.18% and 84.78%. Moreover, the measures of inter-and intra-assay coefficients of variability to express the precision or replicability of ELISA kit results were 5.33% and 2.81%, respectively.

Abstract
Introduction Despite major advances in our understanding of genetic cardiomyopathies, they remain the leading cause of premature sudden cardiac death and end-stage heart failure in persons under the age of 60 years. Integrated research databases based on a large number of patients may provide a scaffold for future research. Using routine electronic health records and standardised biobanking, big data analysis on a larger number of patients and investigations are possible. In this article, we describe the UNRAVEL research data platform embedded in routine practice to facilitate research in genetic cardiomyopathies. Design Eligible participants with proven or suspected cardiac disease and their relatives are asked for permission to use their data and to draw blood for biobanking. Routinely collected clinical data are included in a research database by weekly extraction. A text-mining tool has been developed to enrich UNRAVEL with unstructured data in clinical notes. Preliminary results Thus far, 828 individuals with a median age of 57 years have been included, 58% of whom are male. All data are captured in a temporal sequence amounting to a total of 18,565 electrocardiograms, 3619 echocardiograms, data from over 20,000 radiological examinations and 650,000 individual laboratory measurements. Conclusion Integration of routine electronic health care in a research data platform allows efficient data collection, including all investigations in chronological sequence. Trials embedded in the electronic health record are now possible, providing cost-effective ways to answer clinical questions. We explicitly welcome national and international collaboration and have provided our protocols and other materials on www.unravelrdp.nl.

Abstract
We show that a plasmonic semiconductor substrate can support highly confined surface plasmons when it is covered by a graphene layer. This occurs when the imaginary part of graphene conductivity and real part of the effective permittivity of the surrounding medium become simultaneously negative. Full-wave electromagnetic simulations demonstrate the occurrence of negative refraction and two-dimensional lensing at the interface separating regions supporting conventional right-handed graphene plasmons and left-handed surface plasmon polaritons.

Abstract
The date palm hopper, Ommatissus lybicus, is a key pest of the date palm, which is expected to be comprised of many allopatric populations. The current study was carried out to determine bacterial endosymbiont diversity in the different populations of this pest. Ten date palm hopper populations were collected from the main date palm growing regions in Iran and an additional four samples from Pakistan, Oman, Egypt and Tunisia for detection of primary and secondary endosymbionts using polymerase chain reaction (PCR) assay with their specific primers. The PCR products were directly sequenced and edited using SeqMan software. The consensus sequences were subjected to a BLAST similarity search. The results revealed the presence of 'Candidatus Sulcia muelleri' (primary endosymbiont) and Wolbachia, Arsenophonus and Enterobacter (secondary endosymbionts) in all populations. This assay failed to detect 'Candidatus Nasuia deltocephalinicola' and Serratia in these populations. 'Ca. S. muelleri' exhibited a 100% infection frequency in populations and Wolbachia, Arsenophonus and Enterobacter demonstrated 100, 93.04 and 97.39% infection frequencies, respectively. The infection rate of Arsenophonus and Enterobacter ranged from 75 to 100% and 62.5 to 100%, respectively, in different populations of the insect. The results demonstrated multiple infections by 'Ca. Sulcia muelleri', Wolbachia, Arsenophonus and Enterobacter in the populations and may suggest significant roles for these endosymbionts on date palm hopper population fitness. This study provides an insight to endosymbiont variation in the date palm hopper populations; however, further investigation is needed to examine how these endosymbionts may affect host fitness.

Abstract
PURPOSE To determine the optimal dosage of cyclopentolate for adequate cycloplegia with minimal side effects. METHODS A prospective randomized clinical trial of patients 3.5 to 20 years of age referred to a strabismus clinic during a 1-year period. Eligible patients were randomly divided into three groups. In Group 1, the cycloplegic effect of one drop of cyclopentolate was compared with two drops; in Group 2, the effect of two drops was compared with three drops; and in Group 3, the effect of one drop was compared with three drops. RESULTS This study includes 192 eyes of 96 patients with a mean age of 11.0 +/- 5.7 years. Strabismus was present in 43 patients (44.8%). A total of 146 patients (76%) were hyperopic, 33 (17.2%) were myopic, and 13 (6.8%) were slightly hyperopic or myopic at the two stages of the study. Overall, only 16 eyes, including 9 eyes in Group 1 (16.4%), 2 eyes in Group 2 (3.2%), and 5 eyes in Group 3 (8.6%), had > or = 0.5 D difference in spherical equivalent refractive error at two stages of the study; however, intergroup differences were not statistically significant (p=0.16, chi-square test). Within each group, the percentage of eyes with <0.5 D difference was significantly greater than those with > or = 0.5 D difference (p<0.001 in all three groups, binomial test). Side effects were more prevalent using more frequent drops. CONCLUSIONS A single drop of cyclopentolate 1% suffices for cycloplegic refraction. There were less frequent side effects using one drop of cyclopentolate, compared to two or three drops.

Abstract
PURPOSE Polycarbonate peg has been customarily used for pegging of hydroxyapatite for years. For better movement, tissue tolerance, and to decrease the complications of pegging, titanium peg system has been used. This study compares the two systems. METHODS Complications associated with pegging (polycarbonate: Bio-Eye or titanium: Dr-Perry new P-K) were retrospectively reviewed from the charts of 153 patients admitted to the Labbafinejad Medical Center, Tehran, Iran, for over 5 years from 1997 to 2003. RESULTS A total of 153 cases were studied. Ninety-six (62.3%) were male and 57 (37.7%) were female, and the mean age was 27.7 years (6-59 years). In 88 cases pegs were poly-carbonate and sleeve system and in 65 cases pegs were titanium. Forty-one (46%) of cases with polycarbonate and 18 (27%) of cases with titanium had at least one or more complications (p=0.018). The most common complications were granulation tissue, discharge, overgrowth of conjunctiva, and peg falling out in 25%, 23%, 13%, and 8% in polycarbonate peg and 15%, 5%, 1.5%, and 0% in titanium peg group. The prevalence of the last three complications was statistically lower in titanium peg compared with polycarbonate. Twenty-five cases (35%) with polycarbonate peg and 5 cases (7.5%) with titanium peg had two or more complications (p=0.03). Peg removal was done in 11 cases of polycarbonate but only two cases of titanium peg in order to treat the complication. CONCLUSIONS Both pegging systems had some complications, although these were less severe and prevalent in titanium peg. More studies on complications due to titanium pegs are recommended.

Abstract
INTRODUCTION Recurrent miscarriage (RM) defined as 2 or more spontaneous miscarriage before 20 weeks of gestation, affects at least 1 % of couples trying to conceive. In over 50 % of cases, the cause of the loss of pregnancy remains unexplained. Reduced expression of Angiogenic factors such as: vascular endothelial growth factor (VEGF-A) and VEGF-C has been linked with spontaneous miscarriage, likely due to defective foetal and placental angiogenesis. AIMS AND OBJECTIVES To investigate the relationships between serum level of VEGF-A and VEGF-C with clinical characteristic in women with URM and compare to pregnant and healthy women. MATERIALS AND METHODS A case-control study, which was conducted between 90 non-pregnant women with history of RM, age-matched with 70 non-pregnant women without history of recurrent abortion with at least one child (controls) and 70 pregnant women without history of recurrent abortion with at least one child (controls). Those with unexplained RM were eligible. Demographic and Anthropometric data were retrieved by pre-test questionnaire and serum level of VEGF-A and VEGF-C measured by ELISA kit. RESULTS This study showeds that maternal levels of VEGF-A and VEGF-C were distinctly lower in RSA (189.87±88.1 vs 238.8±99.6) compared to healthy (239.1±99.7 vs 275.5±133.08) and pregnant (301.5±76.4 vs 402.5±128.6) women as control groups. Univariate analysis demonstrated that clinical characteristic factors were significantly associated with concentration of VEGF-A and VEGF-C in cases and controls. CONCLUSIONS Our findings suggest that these molecules could be used as potential predictive markers of miscarriage in these women presenting with URM (Tab. 4, Fig. 5, Ref. 40).

Abstract
A new electrochemical sensor based on gold nanoparticles mesoporous silica modified carbon paste electrode (AuNPs-MPS) was developed for simultaneous determination of hydroquinone and catechol. Morphology and structure of the AuNPs-MPS were characterized by transmission electron microscopy, X-ray diffraction and Fourier transform infrared spectroscopy. The electrochemical behavior of hydroquinone and catechol were investigated using square wave voltammetry and the results indicate that the electrochemical responses are improved significantly at the modified electrode. The observed oxidative peaks separation of about 120mV made possible the simultaneous determination of hydroquinone and catechol in their binary-mixture. Under the optimized condition, a linear dynamic range of 10.0μM-1.0mM range for hydroquinone with the detection limit of 1.2μM and from 30.0μM-1.0mM for catechol with the detection limit of 1.1μM were obtained. The applicability of the method was demonstrated by the recovery studies of hydroquinone and catechol in spiked tap water samples.

Abstract
Variegation in flower color is commonly observed in many plant species and also occurs on Petunia (Petunia hybrida) as an ornamental plant. Variegated plants are of highly valuable in the floricultural market. Agroinfiltration is an Agrobacterium-mediated transient assay for the analysis of gene function and genetic modification in leaves, flowers and fruit tissues of various plants. Transient RNAi-induced silencing by agroinfiltration has been developed in leaves and fruits of several plant species. Here we report the establishment of a transient hairpin RNAi-induced silencing system for color modification assay in floral tissues of Petunia with different colors. chiRNAi construct was cloned into the pBI121 vector under the control of 35S promoter. Transient RNA silencing of chi in the floral tissues of Petunia was induced by delivering 530 bp chi hairpin RNAs (hpRNAs) into the petals of flowers using agroinfiltration. Impaired anthocyanin accumulation and reduction of endogenous mRNAs of the corresponding targets were observed in the infiltrated areas of the petals of four colors of Petunia. Silencing of the endogenous chi mRNAs was highly effective in reduction of chi gene and anthocyanin accumulation. This transient silencing system is a prototype for modification of the anthocyanin biosynthetic pathway in Petunia through chi gene suppression.

Abstract
BACKGROUND Since the amendment of the Social Law V in Germany in 2007 the financial basis for a Specialised Home Palliative Care for Children (SHPC) for children was established. In Hesse 3 different SHPC teams entered into collective negotiations with health insurance companies. In 2014, the team of the University Children's Hospital in Giessen started to treat the first patient with a lead time of two months. METHODS Thus in this paper the development of a SHPC team is described. After the first year anonymized patients data were retrospectively analyzed. RESULTS Within 12 months 35 patients, 24 females and 11 males, were treated. All of the 6 patients who died, died at home. Calculated 48 weeks survival was 78%. 45% of the patients suffered from malignancies, 34% of malformations and 34% had metabolic disorders. 51% needed crisis intervention and 51% infusion therapy. Only 26% of parents denied cardiopulmonary resuscitation (CPR). Only 10% of the patients or their families received professional psychological care. CONCLUSION Formation of a SHPC is feasible within a short time period once a financial basis is established. So, empathic guidance of families to help decision making for emergency situations are considered to be important. Analysis of patient's data after one year could help to improve the quality of care. Our data provides information for developing a palliative care team und could motivate colleagues to start the job.

Abstract
AIM To evaluate the serum levels of anti-tetanus toxin antibodies (anti-TTA) in patients with type 2 diabetes mellitus (DM) and in a control group. METHODS Totally, 100 patients with type 2 DM and 100 age- and sex-matched healthy individuals were enrolled to study. The presence of type 2 DM confirmed according to the clinical and para-clinical criteria such as fasting plasma glucose above 126 mg/dl. A peripheral blood sample was collected from all subjects. The serum samples of participants tested for the levels of anti-TTA by ELISA method. The serum antitoxin concentration 0.1 IU/mL was considered as a protective level of antibody. RESULTS The seroprotective rate in healthy group was significantly higher than diabetic group (99% vs. 92%; p<0.02). The mean titer of anti-TTA in healthy group (5.32 ± 0.26 IU/ml) was also significantly higher than diabetic patients (3.46 ± 0.26 IU/ml; p>0.001). In diabetic men the mean titer of anti-TTA was significantly higher in comparison to diabetic women (3.94 ± 0.34 IU/ml vs 2.59 ± 0.36 IU/ml; p<0.01). In diabetic patients the seroprotective rate and the mean titer of anti-TTA in subjects with age >40 years was also lower in comparison to those with age <40 years (89.23% vs 97.14%; p<0.15 and 4.57 ± 0.38 IU/ml vs 2.86 ± 0.32 IU/ml; P<0.002, respectively). The mean titer of anti-TTA was significantly higher in patients with diabetes duration <5 years in comparison to patients with disease duration >5 years (3.91 ± 0.35 IU/ml vs 2.85 ± 0.38 IU/ml; p<0.04). CONCLUSION these results showed lower levels of anti-TTA in patients with type 2 DM, in diabetic women, in patients aged >40 years and in diabetic patients with disease duration >5 years.

Abstract
BACKGROUND The range of motion after a total knee arthroplasty is an important clinical outcome affecting the life of the patient. The aim of this study was to determine the most important factors influencing the postoperative knee flexion in Tehran, Iran. METHODS Between July 2007 and January 2009, on 95 cases of total knee joint replacement (89 patients), who were followed for 1 year postoperatively, the risk factors were assessed. Patient demographics (sex, age, body mass index, previous surgery, preoperative Knee Society System score, and preoperative range of motion) as well as radiographic measurement for preoperative tibiofemoral angle were statistically analyzed and the probable predictors entered into a linear regression model. RESULTS Univariate analysis showed that age, preoperative flexion angle, preoperative flexion arc and preoperative tibiofemoral angle had significant correlation with the postoperative flexion angle. The linear regression model on the other hand revealed that preoperative flexion angle and preoperative tibiofemoral angle were the true predictors of the postoperative flexion angle with coefficients of 0.64 and -0.21, respectively. CONCLUSION Better range of motion before the surgery with a lower tibiofemoral varus/valgus angle were more likely to result in a better range of motion after the surgery, suggesting that an appropriate timing for the surgery when the knee joint is still in a better function can lead to a better outcome.

Abstract
Primary tooth impaction is a rare finding during the development of primary dentition. Several factors contribute to the impaction of a deciduous tooth. This report describes the diagnosis and treatment of a 10-year-old boy who presented an impacted second primary mandibular molar. This tooth, located inferior to the second premolar together with an odontoma, was positioned superior to the premolar teeth. Treatment consisted of surgical removal of the impacted deciduous tooth and odontoma and placement of a passive lower lingual holding arch. Periodic examination was indicated for follow-up. Early intervention was recommended to manage orofacial disfigurement and to avoid consequent problems.

Abstract
OBJECTIVE This study was designed to describe clinical manifestation, treatment and outcomes in patients with sphenoid sinus mucocele presenting to Amiralam Hospital, Tehran, Iran. METHODS A review of 43280 medical records covering a period of 10 years included just 12 patients with sphenoid sinus mucocele presenting to our teaching centre. RESULTS The mean age of the patients was 35 years (ranging from 19 to 52 years). Headache was the most frequent symptom in 9 of the 12 patients. Visual disorders were noted in five patients. Two patients underwent external ethmoidectomy accompanied by intranasal sphenoidotomy while transseptal sphenoidotomy was performed for five patients and five patients underwent endoscopic endonasal sphenoidotomy. Wide spectrum antibiotics were given to all the patients for 3 to 5 days in order to prevent any iatrogenic infection. All patients did well after surgery without postoperative complications. CONCLUSIONS Sphenoid sinus mucocele should be considered in the differential diagnosis of cystic lesions presenting as visual disturbance. Retro-orbital headache with or without visual symptoms is a leading symptom. CT and MRI are essential in the diagnosis of sphenoid disease.

Abstract
Simpson-Golabi-Behmel syndrome (SGBS) is an overgrowth/multiple congenital anomalies syndrome with an X-linked inheritance. Most cases of SGBS are attributed to mutations in the glypican 3-gene (GPC3), which is highly expressed in the mesodermal embryonic tissues and involves in a local growth regulation. Typical clinical features include pre/postnatal overgrowth, developmental delay, macrocephaly, characteristic facies with prominent eyes and macroglossia, diaphragmatic hernia, congenital heart defects, kidney anomalies, and skeletal anomalies. Obligate carrier females with GPC3 mutations are usually asymptomatic or with mild symptoms. It is thought that skewed X-inactivation is the underlining mechanism for the female patients to present with findings of SGBS. We identified three siblings with typical SGBS (two male and one female cases) and their mother with very mild symptoms in a family carrying c.256C>T (p.Arg86X) mutation in GPC3. X-inactivation studies on the androgen-receptor gene (AR) and the Fragile XE (FRAXE) gene were performed with blood, buccal swabs, and fibroblasts in the carrier females. The studies with blood showed moderately skewed X-inactivation with paternal X-chromosome being preferentially inactivated (71-80% inactivated) in the female patient with SGBS and no skewing was shown in the mother with very mild symptoms. The X-inactivation studies in the mother showed inactivation of the X-chromosome with the mutation by 57%. This suggests that loss of the functional GPC3 protein by 43% is closed to the threshold to develop the SGBS phenotype. Studies with buccal swabs and fibroblasts failed to show different X-inactivation patterns between the two female individuals.

Abstract
In current research, genetic relationships among rapeseed genotypes from several geographical origins including France, Canada, Germany, Iran, Hungary, Denmark, Australia and America were evaluated using RAPD markers. Among generated 86 bands, 80 different polymorphic bands were obtained using 9 random primers. Diversity Index (DI) or Polymorphism Information Content (PIC) was varied from 0.29 to 0.48, showed a relatively high potential of primers among studied genotypes. Dice similarity coefficient between genotypes was calculated using Nei and Li formula. Maximum (0.91) and minimum (0.42) similarity coefficients were observed between Bristol and Amber genotypes, consul and express, respectively. Cluster analysis based on dice similarity coefficient was also carried out. Base on the cluster analysis, genotypes were grouped into five main clusters. Results showed that genotypes with same geographical origin were genetically different. Therefore, geographical origins of genotypes cannot be used as a base to cross parent to obtain high heterosis and it must be carried out by exact genetic studies. Results confirmed that RAPD is a simple, cheap and fast method for evaluation of genetic diversity of Brassica napus.

Abstract
PURPOSE To asses the functional results and complications of Mersilene mesh as an alternative to autogenous fascia lata in the management of low function ptosis. METHODS In a randomized clinical trial, 31 eyelids with poor levator function were operated on. In 16 eyelids Mersilene mesh (Group A) and in 15 eyelids autogenous fascia lata were used for frontalis suspension procedure (Group B). RESULTS Nine patients with congenital unilateral and 11 patients with bilateral ptosis underwent sling procedure. There were no differences between the two groups with regards to functional (lid fissure height stability) and cosmetic (lid margin contour) results. Eyelid fissure increase was 4.00-/+1.46 mm in Group A and 3.13-/+1.72 mm in Group B. Change in eyelid fissure in both groups was significant (p=0.00, paired t-test), but intergroup difference was not significant (p=0.141, independent sample t-test). Follow-up for Group A was 14.2 (range 6-26) months and for Group B was 15.1 (range 9-29) months. Dermatochalasis was seen more in Group B (B/A = 10/2) and extrusion of Mersilene mesh was seen in two cases of Group A and none of Group B. Early complications such as corneal epithelial defects and entropion and late complications such as undercorrection were comparable in the two groups. CONCLUSIONS Mersilene mesh with long-term functional results and low rate of complications is a suitable alternative to autogenous fascia lata as a suspensory material in ptosis surgery.

Abstract
This study surveyed a rapid, efficient and reproducible protocol for in vitro shoot regeneration and rooting by different explants and different concentration of BAP. Due to optimization of shoot regeneration, two media including of MS and modified MS (MS salts with double concentration of CaC21, and B5 vitamins), different explants such as decapitated embryo axes, epicotyls and cotyledonary nodes and different concentrations of BAP hormone (1, 1.5, 2, 2.5, 3 and 4 mg L(-1)) in two genotypes (Gachsaran and Flip. 92-12 L) were used. The results showed that modified MS is a suitable medium for in vitro shoot regeneration of lentil. High levels of BAP caused increasing of shoot regeneration in lentil genotypes. Three milligram per liter of BAP induced the highest level of shoot regeneration. In addition, decapitated embryo explants were the best explants for highest shoot regeneration (5.8) (p < 0.05). However, increasing of hormone concentration from 2 to 3 and 4 mg L(-1) caused decreasing in the number of shoots, so 2 mg L(-1) of BAP was best. For rooting, the in vitro-in vivo method of rooting was better than only in vitro method. The shoots regenerated in 2 mg L(-1) BAP had higher rooting percentage than the shoots were regenerated in 3 and 4 mg L(-1) BAP. These results indicate on the inhibitory effect of high concentration of BAP on root induction. But the genotype didn't have any significant effect on rooting percentage and length of roots.

Abstract
OBJECTIVES To analyse the incidence of concha bullosa and any aetiological correlation with nasal septal deviation. METHODOLOGY Paranasal sinus computerised tomography (CT) scans were made of 143 consecutive patients with sinonasal symptoms. Patients with altered anatomy (iatrogenic or pathological) were excluded and the remaining CT scans were analysed for the pneumatisation of the middle turbinate, septal deviation and the correlation between them. RESULTS Sixty-three percent of patients had some types of septal deviation and 35% had unilateral or bilateral concha bullosa. Septal deviation was present in 9 out of 13 patients (69.2%) with large unilateral or dominant concha bullosa, 10 out of 24 (41.7%) with medium unilateral or dominant concha bullosa, and 12 out of 30 (40%) with small concha bullosa. There was a clear link between the presence of a unilateral concha, or a dominant concha (in bilateral concha), and the presence of nasal septal deviation (P <0.009). CONCLUSIONS After the assessment of various sizes and shape of concha bullosa and the form of nasal septal deviation away from the dominant concha, we suggest that deviation is an indirect result of the presence of the concha. This hypothesis can be proved by reference to the laws of physics.

Abstract
OBJECTIVE Case reports have suggested that lipid-lowering drugs (LLDs), especially statins, could induce or reveal chronic muscle diseases. We conducted a study to evaluate the association between chronic muscle diseases and prior exposure to LLDs. METHOD This was a retrospective study of chronic primary muscle disease cases newly diagnosed at the Toulouse University Hospitals between January 2003 and December 2004 among patients living in the Midi-Pyrénées area, France. All patients remained symptomatic for more than 1 year after drug withdrawal, or required drugs for inflammatory myopathy. Data on the patient's exposure to LLDs and to other drugs were compared with that of matched controls (5/1) selected through the Midi-Pyrénées Health Insurance System database. RESULTS A total of 37 patients were included in the study. Of those, 21 (56.8%) suffered from dermatomyositis (DM) or polymyositis (PM), 12 (32.4%) from genetic myopathy, and 4 (10.8%) from an unclassified disease. The prevalence of exposure to statins was 40.5% in patients and 20% in controls (odds ratio (OR) 2.73, 95% confidence interval (CI) 1.21-6.14; p<0.01). There was a significant positive interaction between statins and proton pump inhibitors exposure (weighted OR 3.3, 95% CI 1.37-7.54; p = 0.02). Statin exposure rate was 47.6% among patients with DM/PM (OR 3.86, 95% CI 1.30-11.57; p<0.01). There was no difference between patients and controls for exposure to fibrates. CONCLUSION Patients who developed chronic muscle diseases after the age of 50, including DM/PM, had a higher than expected frequency of prior exposure to statins. Further studies are needed to confirm this association and the role of proton pump inhibitors.
