Abstract
The growth performance and blood indices of medicated and non-medicated broiler chickens have been the subject of this research coupled with a paucity of comparative information on what can actually happen to broiler chickens if not medicated when reared under humid tropical conditions. One hundred unsexed day-old broilers were randomly and equally allotted into two treatment groups of TM (medicated) and TN (non-medicated) in a completely randomized design each treatment with five replicates having ten birds each. The birds were reared on deep litter system for 56 d which was divided into two phases of 28 d each (starter and finisher), during which data were collected with respect to daily feed intake, final body weight, body weight gained (BWG), mortality rate while blood analysis was carried out on 28th and 56th d for starter and finisher phases, respectively. Non-medicated group served as control. Feed conversion ratio (FCR) and feed conversion efficiency (FCE), were later calculated. Data collected were subjected to analysis of variance statistically. There was no significant difference between the medicated and non-medicated broilers for daily feed intake, final body weight, and BWG and also for the blood parameters investigated at starter phase. However, at finisher phase, no significant difference was observed in the daily feed intake of Tm and Tn but there was significant (P < 0.05) difference in the final body weight, BWG, FCR, FCE, and mortality rate between the two groups. Birds on Tm attained higher weight significantly (P < 0.05) than those on TN. BWG, FCR, and FCE followed the same trend and also the mortality rate. White blood cells count of TN was higher significantly (P < 0.05) than TM while TM birds recorded higher packed cell volume, red blood counts, and hemoglobin concentration (Hb) significantly (P < 0.05) than TM birds. Effect of medication was much noticeable at finisher phase as it improved the growth rate though mortality rate was close to that of TN group. These results suggest that broilers can be produced free of medication with good feeding without loss of birds while the growth rate can be enhanced with the use of prebiotics and prebiotics.

Abstract
Background Sexual differentiation can occur after exposure to aromatase into the left gonad at 6.5 days of incubation. Aromatase inhibitors work by inhibiting the action of the aromatase, which converts androgens into estrogens by a process called aromatization. Objectives The aim of this study was to investigate the effect of in ovo exposure to the aromatase inhibitor from tomato and garlic extract on sexual differentiation and embryonic development in chicken embryos. Methods Three hundred eggs divided into five groups: Control 1 (CO; no injection); control 2 distilled water, DW; 0.1 ml/egg); garlic extract (GAR; 0.1 mg/egg); tomato extract (TOM; 0.1 mg/egg); and garlic and tomato extract mixed (ATM, 0.1 ml/egg). The solution was prepared and injected into the albumin from the thin end of the eggs on day five by using a 1 ml syringe with a 23‐gauge needle. The embryonic test (embryo/egg weight) conducted at 7, 14 and 17 days of incubation. After hatching, feather sexing conducted to determine the initial male. Chicks sex was later confirmed on day 42 by an optical microscope lens. Results The results revealed that there was a significant increase (p < 0.01) in embryonic growth traits in all experimental treatments as compared to control treatments. There was a significant increase (p < 0.01) in the percentage of hatchability for all experimental treatments compared to control treatments and a significant increase (p < 0.01) in chick quality including one‐day‐old chick length and body weight. All experimental treatments showed a significant increase (p < 0.01) in the male‐to‐female ratio compared to control treatments. Conclusions The effect of in ovo exposure to aromatase inhibitors stimulated female‐to‐male sex reversal and improved embryonic development.

Abstract
Background and Aim: Many environmental factors exist that influence embryonic development which is missing in the poultry industry, such as light in incubation facilities or hatcheries. Light plays an important role in the growth and development of chick embryos, whereas dark environments can lead to hatching failure or embryo distortion. Therefore, this study aimed to demonstrate the importance of light and its various colors on the growth and development of broiler chick embryos. Materials and Methods: Four treatments were used to study the impact of various light colors on the growth of embryos and their neurophysiological traits: Dark without light (D), red light (RL), blue light (BL), and green light (GL), with three replicates per treatment (25 eggs/replicate) for a total of 300 fertile Ross 308 eggs. Each treatment was assigned to one incubator (75 eggs/incubator), whereas all other conditions were kept the same. Results: The results showed a significant increase (p<0.01) in embryonic development for embryo weight, chick body weight, hatchability, and embryo index for RL, BL, and especially GL. RL, BL, and especially GL significantly increased (p<0.01) neurophysiological traits of the neurons, brain weight, and brain index. Conclusion: The use of light during the embryonic period affects the development of the embryo and its neurophysiological traits.

Abstract
This study evaluated the effects of licorice extract and probiotic on performance, excreta characteristics and welfare-related parameters of broiler chickens reared in high stocking density. Three hundred and thirty-six 1-day old broiler chicks (Ross 308) were used in a completely randomized design with five treatments and four replicates for 42 days. Treatments were as follows: (a) positive control (PC, 12 chicks/m2 ); (b) negative control (NC, 18 chicks/m2 ); (c) NC + 500 ppm licorice extract (LE); (d) NC + 200 ppm probiotic (P); (e) NC + ppm LE + ppm P. Body weight gain (BWG) was affected negatively by increased density in the growing period (p < 0.05). At high density, BWG was increased in the growing and whole period by adding LE and P separately and in combination (p < 0.01). Feed conversion ratio (FCR) was not affected by stocking density. Excreta weight (g/bird) and dry matter (DM, %) were reduced by increasing density (p < 0.01). Use of feed additives at high stocking density had no significant effect on excreta weight, but DM content of excreta was higher in NC + LE + P than NC. Gait problems and footpad and hock burns were increased by increased stocking density, but were not altered by feed additives. In conclusion, licorice extract and probiotic improved BWG of broilers reared at high stocking density; however, these birds had some disorders in footpad, hock and walking ability.

Abstract
OBJECTIVES AND BACKGROUND Familial Mediterranean Fever (FMF) is characterized by recurrent fever episodes as a result of inflammation of serous membranes. Changes in the number of different mtDNA copy number variations, detected in FMF patients, who developed amyloidosis, might be an important parameter in the understanding of the pathophysiology of the disease. METHODS Changes in the mtDNA copy number between 50 patients with FMF, who had M694V homozygote mutation and amyloidosis, and 50 healthy controls, who had not any MEFV mutation or FMF clinical finding, were examined. The 22 MEFV mutations were analyzed by Pyromark Q24 system. Quantitative analysis was performed on RT-PCR. The level of mtDNA was calculated using the delta Ct (ΔCt) of average Ct of mtDNA and nDNA (ΔCt = Ct mtDNA-Ct nDNA) in the same well as an exponent of 2 (2ΔCt). RESULTS A significant decrease in the amount of mtDNA was detected in FMF patients with M694V homozygous mutation carriers, who developed amyloidosis compared to the control group (p < 0.001). CONCLUSION In this study, mitochondrial dysfunction, which has been identified through changes in the mitochondrial genome in many diseases, was identified by showing that the copy number variations of mtDNA in leukocytes also decreased for FMF disease (Tab. 3, Fig. 1, Ref. 21).

Abstract
The aim of this study was to investigate the effect of Nigella sativa and cephalexin in the therapy of experimental bacterial rhinosinusitis. Bacterial rhinosinusitis was induced with Staphylococcus aureus. Rabbits were divided into five groups; control (n = 6), N. sativa 50 mg/ kg/d (n = 6), N. sativa 100 mg/kg/d (n = 6), N. sativa 200 mg/kg/d (n = 6), and cephalexin 20 mg/kg/d (n = 6) groups. N. sativa was given orally for 7 days. The same volume of normal saline (0.9% NaCl) was given as a vehicle to the control group for the same period. After treatment period, sinus mucosa samples were evaluated using stereological and histopathological methods. Half of the maxillary sinus mucosa samples were frozen at -800C for further analysis of NO levels. Pathology revealed a severe acute inflammatory process in rabbits treated with saline. Only mild inflammation was determined in cephalexin group, N. sativa 100 mg/kg/d and N. sativa 200 mg/kg/d groups. The level of NO increased in the saline group was significantly reduced in all treatment groups. N. sativa may prevent histopathological changes of rhinosinusitis via decreased NO levels in a dose dependent manner and can be used in the treatment of rhinosinusitis diseases.

Abstract
OBJECTIVE Desloratadine is a biologically active metabolite of loratadine which is indicated for the treatment of allergic rhinitis. Bosentan is a dual endothelin receptor antagonist used to treatment of pulmonary artery hypertension (PAH). In this study, we aimed to determine the role of endothelins in allergic rhinitis (AR) and the effects of endothelin receptor antagonists in AR rat models through comparison with desloratadine. METHODS In total, 20 adult Sprague-Dawley rats were used in this study. An ovalbumin-induced allergic rhinitis model was formed in three study groups except for the control group. Bosentan (100 mg/kg/day) was given to the bosentan-treated group for 7 days and desloratadine (10 mg/kg/day) was administered to the antihistaminic-treated group for 7 days. Nasal symptom scorings and histopathological examinations of the nasal tissues were carried out. Serum IgE levels and ET-1 and TNF-alpha mRNA expression levels were analysed. Between group comparisons for nasal symptoms, histopathological analysis, and molecular analyses were performed with a one-way ANOVA and Duncans multiple comparison tests. Significance was accepted at p smaller than 0.05. RESULTS Bosentan inhibited nasal symptom more significantly than desloratadine. The IgE level, ET-1 and TNF-alpha mRNA expression levels statistically increased in the allergic rhinitis group when compared to other groups. Conversely, the bosentan-treatment group showed a significant recovery from the same parameters. The deterioration in histopathological parameters reached the highest levels in the allergic rhinitis group. The histopathological findings were close to those of the control group in the bosentan and antihistaminic-treated group. CONCLUSIONS ET-1 is one of the mediators that impact AR development and ET-1 antagonists can be useful for symptom control and for decreasing allergic inflammation in AR patients.

Abstract
Partial trisomy of chromosome 5 was first described by Lejeune et al. in 1964 on the short arm (12). The vast majority of the partial trisomy 5 cases include 5p duplications; however we reported a small supernumerary marker chromosome. General symptoms include developmental delay, mental retardation, seizures, respiratory difficulties, congenital heart defects, abdominal muscle hypoplasia and dysmorphic features such as macrocephaly, enlarged anterior fontanelle, dolichocephaly, upslanting palpebral fissures, epicanthal folds, hypertelorism, abnormal ears, midface hypoplasia, short nose, broad nasal bridge and microretrognathia. Arachnodactyly and club foot may be seen as cytoskeletal abnormalities and, hypotonia may be determined in neurological exam. Here we reported a case with developmental delay, attention deficit hyperactivity disorder, mild mental retardation and dysmorphic features, caused by a new small supernumerary marker chromosome, generating partial trisomy 5pI 2-q 11.2. To our knowledge, this small supernumerary marker chromosome has not been reported before. Severe type of partial trisomy 5 includes seizures, congenital heart defects, hypotonia and failure to thrive. Previously reported partial trisomy 5 cases, who showed severe phenotype, had usually duplicated 5p13 region. Therefore, patients, who do not have duplicated 5p13, showed mild phenotype. Also, duplication of the long arm of chromosome 5, may contribute to the milder phenotype and the longer survival in partial trisomy 5 patients. Attention deficit hyperactivity disorder, which we described in the present case, may be a result of partial trisomy 5, because it includes ADHD4 gene. This case may help better understanding the karyotype/phenotype correlation related to partial trisomy 5.

Abstract
Warburg Micro Syndrome (WARBM, MIM 600118) is a rare, severe autosomal recessive neurodevelopmental disorder characterized by microcephaly, microphthalmia, microcornea, congenital cataract, cortical dysplasia, corpus callosum hypoplasia, intellectual disability, hypotonia and hypogonadism. RABS, small G proteins belonging to the RAS superfamily, are master regulators of vesicle trafficking in the cell. The identification of mutations in the RAB3GAP1 and RAB3GAP2 genes, which together encode the RAB3GTPase-activating protein, a key regulator in calcium-mediated exocytosis of neurotransmitters and hormones, has underpinned abnormal development of the brain, eye and genitalia as cardinal features of this syndrome. More than 100 patients have been reported with WARBM, with mutations in the RABGAP1, RABGAP2, RAB18 and TBC1D20 genes. The objective of the study was to describe the recurrent RAB3GAP1 mutations and compare the clinical features of the patients with WARBM in the Turkish population. Here we report two brothers with Warburg Micro Syndrome 1 from a non-consanguineous Turkish family with clinical features similar to those previously reported in Turkish patients with RAB3GAP1 mutations. We found that the c.748+1G>A splice-site mutation in RAB3GAP1 intron 8 is common and has so far only been detected in patients of Turkish ethnic origin. Although one of our patients has a distal extra crease on the 4th finger and another has nephrolithiasis, there does not appear to be any specific phenotypic findings associated with this mutation.

Abstract
In this experimental design, we explored the neuroprotective potential of zingiberene (ZGB), a monocyclic sesquiterpene, in hydrogen peroxide (H2O2)-induced toxicity in newborn rat cerebral cortex cell cultures for the first time. The rats were exposed to H2O2 for 6 h to determine the oxidative stress levels. To evaluate cell viability, both 3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyltetrazolium bromide and lactate dehydrogenase assays were carried out. Total antioxidant capacity (TAC) and total oxidative stress (TOS) parameters were used to evaluate oxidative changes. Besides determining 8-hydroxy-2-deoxyguanosine (8-OH-dG) levels in vitro, single-cell gel electrophoresis was also performed to measure the resistance of neuronal DNA to H2O2- exposed rats. Our results showed that survival and TAC levels of the cells decreased, while TOS, 8-OH-dG levels and the mean values of the total scores of cells showing DNA damage increased in the H2O2 alone-treated cultures. But pretreatment of ZGB suppressed the cytotoxicity, genotoxicity and oxidative stress that were increased by H2O2. Based on these observations, it is suggested that the sesquiterpene ZGB can be used as a novel and natural potential therapeutic in counteracting oxidative damages in the field of neurodegenerative disorders.

We present a male child at 3 years old with Anophthalmia-Plus Syndrome (APS). He has asymmetry of the face and head, left choanal atresia, a sunken facial appearance, microphthalmia in the right eye, severe microphthalmia in the left eye, bilateral low-set ears, scarring from cleft palate surgery. Magnetic resonance imaging (MRI) sections revealed decreased right globe volume, an undeveloped left globe, decreased left optical nerve thickness, Chiari type 2 malformation, left choanal atresia and cleft palate. Echocardiography and abdominal ultrasonography were normal. The patient has a 45 dB conductive hearing loss in the left ear. Repeated thyroid function tests were evaluated as compatible with central hypothyroidism. We report a Fryns Anophthalmia-Plus Syndrome in a child with unusual findings including central hypothyroidism, chiari type 2 malformation, conductive hearing loss and developmental regression. Summary of the features reported in the present case and all 14 previous cases that might be defined as APS.

Abstract
We describe a 2-month-old girl with congenital anomalies including facial anomalies, complex cardiac anomalies, polysyndactyly, dysgenesis of distal extremities and bilateral multiple renal cysts. The proband was the child of first-cousin parents. Clinical synopsis in Bonneau syndrome (OMIM: 263630) is polysyndactyly and cardiac malformation. In addition, liver anomalies were reported in two patients. We discuss polysyndactyly and cardiac malformation with bilateral multiple renal cysts, a combination not reported previously.

Abstract
A dysmorphic newborn with 45,x,der(1)inv(1)(p13;qter)t(y;1)(pter-->q11;p13),-Y de novo karyotype: Y/autosome translocations are very rare chromosomal rearrangements. In most cases, the long arm of the Y chromosome is translocated onto an autosome and most patients are referred because of male infertility. Y/1 translocations are very rare, and have been reported in seven patients so far. Pericentric inversions may be seen in all chromosomes and are not associated with phenotypic abnormalities. Here we report a 6-day old male baby with prenatal growth retardation, frontal bossing, hypertelorism, micrognathia, cleft soft palate, absent uvula, hypospadias, simian line in both hands and hammer toes. Cytogenetic analysis was performed with GTG-banding, C-banding and FISH analysis containing X centromeric probe, Yq12-qter locus specific probe and whole chromosome Y probe. An unbalanced Y/1 translocation was diagnosed: 45,X,der(1)inv(1)(p13;qter)t(Y;1)(pter-->q11;p13),-Y.
