Abstract
In the classical Inverse Electron-Demand Diels-Alder (IEDDA) reactions between alkenes and tetrazines, 4,5-dihydropyridazines are formed. 4,5-Dihydropyridazines are rapidly converted to the more energetically stable 1,4-dihydropyridazines by 1,3-prototropic isomerization. In this study, instead of 1,4-dihydropyridazines, 4,5-dihydropyridazine-3(2H)-ones were obtained as a result of IEDDA reactions between tetrazines with leaving groups at the 3,6-positions, and norbornene and barrelene-derived polycyclic alkenes in the presence of moisture in air or solvent. To show that this new method works not only on strained polycyclic alkenes but also on monocyclic and linear alkenes, the corresponding 4,5-dihydropyridazine-3(2H)-ones were obtained in high yields from the reactions performed with styrene and cyclopentene as well. The chemical structures of the polycyclic 4,5-dihydropyridazine-3(2H)-ones were determined by NMR and HRMS analyses. In addition, the exact structures of the polycyclic 4,5-dihydropyridazine-3(2H)-ones were also experimentally proven by converting them to pyridazine-3(2H)-ones known in the literature.

Abstract
Pistachio is a nut crop domesticated in the Fertile Crescent and a dioecious species with ZW sex chromosomes. We sequenced the genomes of Pistacia vera cultivar (cv.) Siirt, the female parent, and P. vera cv. Bagyolu, the male parent. Two chromosome-level reference genomes of pistachio were generated, and Z and W chromosomes were assembled. The ZW chromosomes originated from an autosome following the first inversion, which occurred approximately 8.18 Mya. Three inversion events in the W chromosome led to the formation of a 12.7-Mb (22.8% of the W chromosome) non-recombining region. These W-specific sequences contain several genes of interest that may have played a pivotal role in sex determination and contributed to the initiation and evolution of a ZW sex chromosome system in pistachio. The W-specific genes, including defA, defA-like, DYT1, two PTEN1, and two tandem duplications of six VPS13A paralogs, are strong candidates for sex determination or differentiation. Demographic history analysis of resequenced genomes suggest that cultivated pistachio underwent severe domestication bottlenecks approximately 7640 years ago, dating the domestication event close to the archeological record of pistachio domestication in Iran. We identified 390, 211, and 290 potential selective sweeps in 3 cultivar subgroups that underlie agronomic traits such as nut development and quality, grafting success, flowering time shift, and drought tolerance. These findings have improved our understanding of the genomic basis of sex determination/differentiation and horticulturally important traits and will accelerate the improvement of pistachio cultivars and rootstocks.

Abstract
Two limiting cases of molecular recognition, induced fit (IF) and conformational selection (CS), play a central role in allosteric regulation of natural systems. The IF paradigm states that a substrate "instructs" the host to change its shape after complexation, while CS asserts that a guest "selects" the optimal fit from an ensemble of preexisting host conformations. With no studies that quantitatively address the interplay of two limiting pathways in abiotic systems, we herein and for the first time describe the way by which twisted capsule M-1, encompassing two conformers M-1(+) and M-1(-), trap CX4 (X=Cl, Br) to give CX4 ⊂M-1(+) and CX4 ⊂M-1(-), with all four states being in thermal equilibrium. With the assistance of 2D EXSY, we found that CBr4 would, at its lower concentrations, bind M-1 via a M-1(+)→M-1(-)→CBr4 ⊂M-1(-) pathway corresponding to conformational selection. For M-1 complexing CCl4 though, data from 2D EXSY measurements and 1D NMR line-shape analysis suggested that lower CCl4 concentrations would favor CS while the IF pathway prevailed at higher proportions of the guest. Since CS and IF are not mutually exclusive, we reason that our work sets the stage for characterizing the dynamics of a wide range of already existing hosts to broaden our fundamental understanding of their action. The objective is to master the way in which encapsulation takes place for designing novel and allosteric sequestering agents, catalysts and chemosensors akin to those found in nature.

Abstract
Hawthorn (Crataegus spp.) is an edible wild fruit that is used in traditional medicine, landscape studies, and food and beverage industries in many countries. It is an important wild plant species in Turkey and is numerous in the Yozgat Province. Genetic and breeding studies on hawthorn are very limited. Therefore, we aimed to characterize 91 hawthorn genotypes using simple sequence repeat (SSR) markers. The SSRs were developed from apple and pear and were screened in hawthorn for amplification and polymorphisms. A total of 265 alleles were detected from thirty-two SSR primer pairs, and those were used to identify genetic relationships. The number of alleles ranged from 2 to 21 alleles per locus with a mean value of 8.28. The Hi05b09 locus showed the highest allele number (Na = 21). The polymorphism information content (PIC) values ranged from 0.16 (CH03d10) to 0.89 (C6554) with a mean value of 0.60. An Unweighted Pair Group Method with Arithmetic Average method was used to cluster the genotypes, and four major clusters were obtained from the amplification of the SSRs. STRUCTURE software identified four populations (ΔK = 4) and eight sub-populations (ΔK = 8), and four major clusters similar results to UPGMA analysis. Our study showed that the SSR markers could be utilized as a reliable tool for the determination of genetic variations and relationships of hawthorn genotypes. A basic molecular analysis on the hawthorn genotypes identified in this study will promote the collection of germplasm collection and the selection of parents' in future cross-breeding studies.

Abstract
BACKGROUND Kumquat (Fortunella spp.) is one of the important fruit species that has been introduced into Turkey recently. It is well adapted to the Mediterranean region in Turkey. Early research of kumquat was started on adaptation and pomological traits, and only a few studies have been concerned with chemical content. After understanding the health benefits of kumquat fruits farmers started their plantations in Turkey. Thus in this study the fruits of five kumquat species - Fortunella margarita (Lour.) Swingle, F. crassifolia Swingle, F. obovata Hort. ex Tanaka, F. hindsii (Champ. ex Benth.) Swingle, and limequat [Citrus aurantifolia × F. japonica (Thumb.)] - were compared based on their lipids, fatty acids and volatile profiles. The lipids, fatty acids and volatile profiles were determined by using gas chromatography with flame ionisation detection (GC/FID) and headspace gas chromatography mass spectrometry (HS-GC/MS) techniques. Volatile constituents of kumquat fruits were isolated by a headspace method. RESULTS The total lipid content (%) of kumquat species ranged from 0.26% to 0.37%. The polyunsaturated fatty acids were detected in a higher amount compared to the monounsaturated fatty acids and saturated fatty acids, respectively. The headspace technique led to the identification of 39 compounds and among a total of 39 constituents identified, d-limonene was the most abundant compound, comprising 67.78-88.72%. The results indicated that kumquats are rich in dietary and health benefits. CONCLUSION Thirty-nine compounds were identified and terpenes were the major chemical group in all kumquat genotypes. Esters, alcohols, aldehydes and ketones were also detected. The present study revealed that the kumquat fruits have a valuable levels of health beneficial chemo-preventive effects and genotypes varied based on their lipid, fatty acids and volatile constituents.

Abstract
Background Pistachio (Pistacia vera L.) is a dioecious species that has a long juvenility period. Therefore, development of marker-assisted selection (MAS) techniques would greatly facilitate pistachio cultivar-breeding programs. The sex determination mechanism is presently unknown in pistachio. The generation of sex-linked markers is likely to reduce time, labor, and costs associated with breeding programs, and will help to clarify the sex determination system in pistachio. Results Restriction site-associated DNA (RAD) markers were used to identify sex-linked markers and to elucidate the sex determination system in pistachio. Eight male and eight female F1 progenies from a Pistacia vera L. Siirt × Bağyolu cross, along with the parents, were subjected to RAD sequencing in two lanes of a Hi-Seq 2000 sequencing platform. This generated 449 million reads, comprising approximately 37.7 Gb of sequences. There were 33,757 polymorphic single nucleotide polymorphism (SNP) loci between the parents. Thirty-eight of these, from 28 RAD reads, were detected as putative sex-associated loci in pistachio. Validation was performed by SNaPshot analysis in 42 mature F1 progenies and in 124 cultivars and genotypes in a germplasm collection. Eight loci could distinguish sex with 100% accuracy in pistachio. To ascertain cost-effective application of markers in a breeding program, high-resolution melting (HRM) analysis was performed; four markers were found to perfectly separate sexes in pistachio. Because of the female heterogamety in all candidate SNP loci, we report for the first time that pistachio has a ZZ/ZW sex determination system. As the reported female-to-male segregation ratio is 1:1 in all known segregating populations and there is no previous report of super-female genotypes or female heteromorphic chromosomes in pistachio, it appears that the WW genotype is not viable. Conclusion Sex-linked SNP markers were identified and validated in a large germplasm and proved their suitability for MAS in pistachio. HRM analysis successfully validated the sex-linked markers for MAS. For the first time in dioecious pistachio, a female heterogamety ZW/ZZ sex determination system is suggested.

Abstract
Unlike most angiosperms, in which fertilization occurs within several days after pollination, fertilization in hazel (Corylus Spp.) is delayed by two to three and a half months. However, the female inflorescences or young fruits are too hard or lignified to be dissected according to regular paraffin sectioning technique. So, what the nature of development during the extended progamic phases of hazel remains unknown. The female inflorescence development and pollen tube growth mode during the delayed fertilization stage in hazel were investigated by improved paraffin sectioning and aniline blue staining of pollen tubes. The results showed ovaries and ovules of hazel were invisible at the time of blooming. Early ovary and ovule primordium began to form from 15 to 20 days after blooming, respectively. Integument and mature embryo sacs differentiated from the nucellus on 40th and 55th day after blooming, respectively. Pollen tubes were retarded in the bottom of the style or the pollen tube cavity (PTC, a specifical lignified cavity structure at the bottom of style for pollen tube to rest during progamic phase) for about 26 days. Then, the pollen tubes were observed to leave the PTC and began to enter the ovary. After that, a single pollen tube passed through the vicinity of the micropyle. Finally, pollen tubes turned a corner and penetrated the embryo sac through the tissue of the chalaza instead of micropyle on 52 and 55 days after blooming, respectively. The results of more in-depth information will be beneficial to better understanding of the delayed fertilization process in hazel.

Abstract
The oxidation of some cyanocycloheptatrienes with CrO3 and pyridine was investigated and a few new nitrile functionalised benzotropone derivatives were obtained. Photooxygenation reaction of these products was also studied. The structures of the formed products were determined on the basis of NMR spectroscopy and the formation mechanism of unusual products was discussed. Human carbonic anhydrase isoenzymes I, and II (hCA I and hCA II) inhibition properties of nitrile functionalized new benzotropone derivatives were also studied. Both CA isozymes were inhibited in the low micromolar range by these nitrile functionalized benzotropone analogues. The newly synthesized benzotropone derivatives showed inhibition constants in the sub-micromolar range (2.51-4.06μM). The best hCA I inhibition was observed in 5H-benzocycloheptene-7-carbonitrile (Ki: 2.88±0.86μM). On the other hand, 5-oxo-5H-benzocycloheptatriene-7-carbonitrile showed the powerful inhibitory effect against hCA II (Ki: 2.51±0.34μM).

Abstract
A 30-year-old woman was diagnosed with ulcerative colitis in January 2006. One year later, she presented because of severe back pain and was diagnosed with ankylosing spondylitis (AS). In February 2008, the patient, while still under standard treatment for ulcerative colitis and AS, was admitted because of massive proteinuria and related symptoms. Nephrotic syndrome was observed and renal biopsy revealed amyloid deposits. After treatment with infliximab, nephrotic syndrome disappeared. We aim to present a case of secondary amyloidosis complicating ulcerative colitis and associated spondyloarthropathy.

Abstract
We present the case of a woman with a giant endometrial polyp of uncommon dimension who was receiving adjuvant tamoxifen for breast cancer. In her gynecologic examination, she had a mass measuring 3 x 4 x 4 cm protruding from the cervical os. The mass was extirpated under general anesthesia. The mass originated from the endometrial cavity. The endometrial polyp measured 10 x 6 x 3 cm macroscopically and was found to be benign under microscopic examination. We conclude that physicians should be aware of the confounding effects of tamoxifen on the histological and ultrasonographic appearance of the endometrium.

Abstract
OBJECTIVE To study whether endometrioid type malignant endometrial polyps (MEP) are different from endometrium cancer not associated with polyps (ECNAP) in means of immunohistochemical expressions of MMP-2, MMP-9 and COX-2. METHODS Archived tissue samples of eight MEP, eight ECNAP and 16 benign endometrial polyps were selected and immunohistochemically analyzed for MMP-2, MMP-9 and COX-2 expression. RESULTS MMP-2 and MMP-9 were overexpressed in ECNAP compared to MEP and benign endometrial polyps (p < 0.05). MMP-2 and MMP-9 expressions were not different in the malignant part of MEP, benign part of MEP and benign endometrial polyps. COX-2 expression was found to be higher in benign lesions, although this was not statistically significant. CONCLUSION Similar immunohistochemical expression of MMP-2, MMP-9 and COX-2 within a polyp and with benign polyps may indicate an immunohistochemically indolent characteristic of MEP.

Abstract
The bromination of 6,7,8,9-tetrahydro-5H-5,9-ethenobenzo[a][7]annulene yielded regio- and stereospecifically formed dibromides arising from the alkyl shift where the bromine exclusively attacks the double bond from the endo face of the double bond. DFT calculations on model compounds showed that the pyramidalization of the double bond and steric repulsion caused by the methylene protons are responsible for the stereo- and regioselective addition of bromine.

Abstract
OBJECTIVE To evaluate the efficacy of intrauterine lidocaine plus buccal misoprostol in reducing the discomfort caused by endometrial biopsy with a suction curette. METHODS In this double-blind, randomized, placebo-controlled trial 126 women undergoing endometrial biopsy were administered a 200-microg tablet of misoprostol buccally, followed by a 5-mL uterine instillation of either of 2% lidocaine or a saline solution. The main outcome measures were the intensity of pain during, immediately following, and 20 min following the biopsy, as assessed on a 10-cm visual analog scale. Statistical analysis was performed using the Friedman test with the Bonferroni correction, the t test, and the chi(2) test. RESULTS There were no statistically significant differences between the study and control groups in mean age, parity, or relevant medical history. A statistically significant difference in pain scores was noted in premenopausal women during the procedure (lidocaine, 4.93+/-1.67; placebo, 6.17+/-1.26; P<0.001) as well as immediately later (lidocaine, 4.12+/-1.14 vs. placebo, 5.42+/-1.08; P<0.001) and 20 min later (lidocaine, 3.60+/-1.10; placebo, 4.22+/-1.46; P<0.001). No significant differences in pain scores were observed in postmenopausal women for any of the 3 time points (6.72+/-2.01, 5.18+/-1.22, and 4.56+/-0.80, respectively; P>0.05). The number needed to treat was 2.6 (95% confidence interval, 1.9-4.8). CONCLUSION Intrauterine lidocaine plus buccal misoprostol appears to be effective in decreasing pain in premenopausal women undergoing endometrial biopsy with a suction curette.

Abstract
OBJECTIVE Matrix metalloproteinases (MMPs) are key players in the degradation of extracellular matrix and basement membranes, and are thus important in tumor invasion. Gelatinases (MMP-2 and MMP-9) in particular are prognostic factors in many solid tumors. In this study the immunohistochemical expression of both COX-2 and matrix metalloproteinases has been shown for the first time in endometrium carcinoma. METHODS Forty-two endometrial carcinoma tissues were immunostained for MMP2 antibody (1:100, Rabbit polyclonal), MMP9 antibody (1:100, Rabbit polyclonal) and CoX2 antibody (1:100, Epitope specific rabbit antibody). RESULTS 90.5% of the cases were positive for MMP-2 and MMP-9, and 83.3% of the cases were positive for COX-2. A statistically significant association was found between COX-2 overexpression and FIGO stage (p = 0.001). A positive correlation was also found with histological grade (p = 0.006), myometrial invasion (p = 0.033), vascular invasion (p = 0.017), and lymphatic invasion (p = 0.007). A positive correlation was found between MMP-2 overexpression and vascular and lymphatic invasion (p = 0.030 and p = 0.003, respectively). MMP-9 overexpression was also found to be correlated with vascular and lymphatic invasion (p = 0.001 and p = 0.012, respectively). Furthermore, there was a statistically significant correlation between MMP-2 and MMP-9 overexpression (p = 0.0001). CONCLUSION The results showed that COX-2, MMP-2 and MMP-9 were expressed in a high percentage of primary endometrial carcinomas and their expressions may be associated closely with parameters of tumor aggressiveness.

Abstract
OBJECTIVE CD24 is a cell adhesion molecule that has been implicated in metastatic tumor progression of various solid tumors. Its expression is known to be related to the prognosis of several kinds of tumors. This study was designed to examine the prognostic significance of CD24 in endometrial cancer patients. METHODS Forty-four endometrial carcinoma tissues were immunostained for CD24 antibody (Ab2, clone 24 C02). Cytoplasmic and membranous immunoreactivity were scored semiquantitatively by Fisher's exact test. RESULTS CD24 expression was detected in 34 (77.3%) out of 44 cases. Membranous and cytoplasmic staining of CD24 was significantly associated with the International Federation of Gynecology and Obstetrics (FIGO) grade (p = 0.011 and p = 0.002, respectively) and nodal status (p = 0.002 and p = 0.000, respectively). CONCLUSION Our data suggests that CD24 expression in endometrial carcinoma as detected by immunohistochemistry might be a new marker for a more aggressive endometrial cancer biology. CD24 is commonly up-regulated in endometrial cancer and this corroborates the importance of CD24 in tumor progression among these cases.

Abstract
Benign cystic teratoma of the ovary (BCTO) is the most common ovarian germ cell tumor occurring predominantly in early adulthood. Malignant transformation of a BCTO is rare, with an incidence of 2%. Most benign cystic teratomas with malignant transformations are squamous cell carcinomas with just 6.8% being adenocarcinomas. We present a rare case of adenocarcinoma arising from the gastrointestinal epithelial elements of BCTO based on the microscopic examination and immunohistochemical studies. Adenocarcinoma arising from gastrointestinal epithelium within BCTOs is extremely rare. This is the fifth reported case of adenocarcinoma arising in gastrointestinal epithelium of a BCTO.

Abstract
The cycloaddition reaction of 7-substituted 5H-benzocycloheptenes with singlet oxygen and the chemistry of the obtained endoperoxides were investigated. Reaction of carboethoxy-substituted endoperoxide with NEt3 gave a mixture of products; hydroxyketone, diketone, and carboethoxy-substituted ketoenol tautomers, whereas the reaction of methyl-substituted endoperoxide only formed a diketone under the same reaction conditions. Thermolysis, thiourea, and CoTPP reactions of the endoperoxides were also studied. The reaction mechanism and electronic effect of substituents were discussed.Key words: benzocycloheptene, photooxygenation, endoperoxides, rearrangement, CoTPP.

Abstract
Pregnancy in a rudimentary uterine horn is rare and is usually associated with fetal death and serious maternal morbidity and mortality. A case of pregnancy in a rudimentary uterine horn with rupture 14 weeks after last menstrual period and is complicated with placenta accreta is presented. The patient had signs and symptoms of massive hemoperitoneum. An emergency exploratory laparotomy revealed rupture of the gravid rudimentary horn of a bicornuate uterus. Histologic examination of the specimen showed that placenta was accreta. The relative literature is reviewed and the association of placenta accreta in such situations is pointed out.

Abstract
BACKGROUND The neuroanatomic and pathologic basis of Tourette's syndrome or related disorders such as obsessive-compulsive disorder and attention deficit-hyperactivity disorder remains unknown. Although a substantial body of neuroimaging and other data implicate basal ganglia and some point out specifically the globus pallidus in the etiopathogenesis of these three related disorders, no clear or pathologically significant isolated lesions restricted to this region have yet been demonstrated, with the exception of obsessive-compulsive disorder. METHODS A seventeen-year-old male case of Tourette syndrome with comorbid obsessive-compulsive disorder, attention deficit-hyperactivity disorder, stuttering and gait disturbance, who had negative family history is presented. RESULTS The patient has failed to respond to drug treatment and his MRI scan revealed bilateral and symmetrical globus pallidus lesions with specific "tiger's eye" appearance of unknown etiology. CONCLUSIONS Well-localized lesions in the globus pallidus support growing data suggesting the involvement of this brain region in Tourette syndrome and related disorders.

Abstract
BACKGROUND/AIMS The large bowel is injured in about 10% of penetrated abdominal injuries. Primary repair with colostomy has been discussed recently. MATERIALS AND METHODS Between 1987 and 1995, sixty-five patients were operated on with penetrated colon injuries were treated with primary repair without colostomy. Any patient with one or more of the following criteria was excluded: Age > 60 years, blood pressure < 80/60 mmHg, time from injury to treatment > 8 hours, Penetrating abdominal trauma index > 50. RESULTS The mean age of the patients was 31 and female/male ratio was 1/7. Fifty-one patients (78.5%) were exposed to colon injury by stabbing and 14 patients (21.5%) by gunshot. The most frequently injured segment was the transverse colon (36.9%). The liver was the most commonly injured organ associated with colon injury (32.3%). Colon wounds of 48 patients (73.8%) were treated with simple repair consisting of meticulous debridement. All gunshot wounds (14 patients) and 3 of the stab wounds were treated with segmentary resection and two layered anastomosis because of the massive colonic wall injury and/or impairment of the blood supply. The most common postoperative complication was wound infection (12.3%). Intraabdominal infection and leakage of the anastomosis were not observed. CONCLUSION Primary repair or, if necessary, segmentary resection and anastomosis will be more appropriate in civilian colon injuries.
