In silico EST-SSRs Analysis in UniGene of Quercus robur L.

Pedunculate oak (Quercus robur L.) is one of the most important tree componentsof Europe’s forest ecosystems, possessing both ecological and economical value. Development of genomic resources, such as genetic markers, is needed to support geneconservation and tree improvement activities. Experimental methods to develop SSR markers are laborious, time consuming and expensive, while in silico approaches havebecome a practicable and inexpensive alternative in genetic studies. The aim of this studywas to characterize simple sequence repeat (EST-SSR) markers and functional annotationof SSR containing sequences in Q. robur unigene sequences. 7170 unigene sequences(5147.315 kb) of Q. robur were downloaded from National Center for BiotechnologyInformation (NCBI). A total of 475 (6.62 %) unigene sequences containing 525 SSRs (microsatellites) were identified by using MISA software. The average frequency ofmicrosatellites was found, on average, one in every 9.8 kb of sequence. The analysisrevealed that tri-nucleotide repeats (42.6%) were most abundant followed by dinucleotide(36.9%), hexa-nucleotide (11.8%), penta-nucleotide (4.9%) and tetra-nucleotiderepeats (3.8%), respectively. Flanking sequences of the 525 SSRs generated 500 primers(95.2%) with forward and reverse strands by using Primer3 software. Gene based SSRmarkers can be used for studies of genetic diversity, population genetics, geneticmapping, gene tagging and more. Large numbers of unigenes containing SSRs (77.4%),annotations were available 46.75% of which were predicted, 23.91% were hypothetical,8.83% were putative and 20.51% belonged to other protein types. Only 22.5% sequencecould not assign to any specific protein class

Association analysis of Epworth Sleepiness Scale (ESS) scores with serotonin transporter (5-HTT- LPR, 5-HTT-VNTR) and circadian (PER3-VNTR) genes

Excessive daytime sleepiness (EDS) is a common complaint encountered in clinical practice with serious consequences both for individual and society since it can increase the ratio of motor vehicle accidents, work- related incidents, and deaths. Moreover, it also manifests less serious individual consequences. This study aimed to investigate the potential role of PER3-VNTR, 5-HTT-LPR, and 5-HTT-VNTR in terms of constituting liability to EDS. Two hundred eighteen participants (93 complaining about daytime sleepiness and 125 individuals with no serious complaint) were recruited in the study. General daytime of sleepiness was quantified with Epworth sleepiness scale (ESS). DNA extractions were performed from collected blood samples with standart salting-out procedure and genotyped. ESS scores displayed difference between individuals suffering from sleep disturbances and other individuals with values of 12.75±4.55 and 6.34±4.26, respectively. PER3- VNTR and 5-HTT-LPR genotypes did not display association with mean ESS scores. However, 5-HTT-VNTR genotypes showed significant association with mean ESS scores; individuals with 10/10 genotypes had the highest ESS score reflecting this genotype as a liability factor for EDS. We strongly recommend further studies based on circadian/serotonin pathway genes in different populations to reach to a consensus and highlight sleep genetic marker genes which then can be the future targets of pharmacological treatment studies for sleep problems

Ollier disease anaplastic mixed oligoastrocytoma a rare association with brain tumors

WOS: 000242312600008Ollier disease, or multiple enchondromatosis, is characterized by multiple, asymmetrically distributed intraosseous cartilaginous masses in the metaphyses and diaphyses of bones. It is rarely associated with neoplasm. We report a 28-year-old woman with a history of Ollier disease, who developed recurrent cerebral anaplastic mixed oligoastrocytoma

Malformations of cerebral cortical development clinical and imaging features

WOS: 000244793500004Malformations of cortical development (MCDs) comprise a variable spectrum of clinical, neuroradiologic, and histopathologic findings. MCDs are increasingly recognized as significant causes of epilepsy, developmental delays, and congenital neurologic deficits. The aim of this study was to determine the types, relative frequencies, and clinical and imaging features of MCDs. Data were collected in 2 hospitals and a medical imaging center during a 9-year period. Twenty-six patients (17 men and 9 women; age range, 5 mo to 29 y; mean age, 10.8 y) with an MCD were evaluated. The results of magnetic resonance imaging studies were retrospectively reviewed for type, extension, and classification of the malformations and for associated findings. Clinical findings were obtained by a review of the patients' medical records. Of the patients studied, epilepsy was present in 65%, mental and/or motor retardation was identified in 34.6%, and skin lesions were noted in 15%. The following types of MCD were identified: malformations of the heterotopic gray matter in 35% of the subjects, focal cortical dysplasia (23%), subependymal and cortical tubers (19%), pachygyria (15%), polymicrogyria (15%), schizencephaly (15%), and type 1 lissencephaly (8%). Approximately, 27% of the subjects had the following other types of cerebral malformation: callosal agenesis (8%), ventriculomegaly (8%), or agenesis of the septum pellucidum (4%). Our study indicated that the most common forms of MCD are heterotopia and focal cortical dysplasia. Patients with an MCD tended to have a higher prevalence of epilepsy, developmental delays, and neurologic deficits. Most patients with heterotopia had other malformations of cortical dysplasia. Some patients with an MCD also exhibited other malformations of the brain

Hemifacial spasm and hypoacusia due to vascular loop compression - Case report and review

WOS: 000248998100013Vascular loop compression is the term used to classify a group of conditions thought to be caused by the compression of cranial nerve by vessel. The vascular abnormality is usually an atherosclerotic aberrant or ectatic intracranial artery, most commonly the anterior and posterior cerebellar artery or the vertebral artery. Hemifacial spasm is a well-recognized clinical feature of vascular compression of the facial nerve. Unilateral auditory symptoms due to eighth nerve involvement with vascular compression have also been reported. Involvement of both seventh and eighth nerves together is a rare condition and imaging features have not been established well. Here, we report a 50-year-old man with hemifacial spasm and unilateral hypoacusia associated with compression of left facial and auditory nerve complex by basilar vascular loop

Multiple supratentonal and infratentorial cavernous malformations

WOS: 000256162100013Although cerebral cavernous malformations can be encountered through the entire central nervous system, they are frequently seen in the cerebral hemispheres. In this case report,the magnetic resonance features of multiple cavernous hemangiomas involving rarely seen infratentorial areas besides the supratentorial areas are presented. A 25-year-old woman was admitted with complaints of headache and seizures. Her neurologic examination was normal. Cerebral magnetic resonance imaging revealed typical appearances of multiple cerebral cavernous malformations. T2-weighted gradient echo magnetic resonance images showed numerous millimetric hypointense "black dot" lesions with a marked susceptibility effect (hypointense "blooming") caused by a peripheral rim of hemosiderin in the cerebral hemispheres, brainstem, and cerebellum

Epilepsili Hastalarda Periferik Sinir Aksonal Eksitabilitesi

Giriş: Sodyum (Na ) kanalları hem santral sinir sistemi hem de periferik sinir sisteminde (PSS) aksiyon potansiyeli oluşumunda önemli bir role sahiptir. Persistan Na+ akımı, uzamış depolarizasyonun neden olduğu aksiyon potansiyellerinin repetetif ateşlenmesinde rol oynar ki bu epilepsiye neden olabilir. Sinir eksitabilite ölçümleri, insanların periferik aksonlarında impuls iletiminin biyofiziksel özellikleri ve bozukluklarını incelemek için yapılmaktadır. Metod: Bu çalışmada, PSS'de de benzer kanallar olmasından yola çıkılarak epilepsili hastaların periferik sinir duysal ve motor aksonlarında persistan Na+ akımında değişiklik olup olmadığını değerlendirmek için motor ve duysal aksonların güç-süre özelliklerini çalışmak amaçlanmıştır. Çalışmaya antikonvülzan tedavi almayan, yeni tanı almış parsiyel epilepsili 17 hasta ile primer jeneralize epilepsili 22 hasta ve 15 kontrol olgu alındı. Sonuçlar: Epilepsili olgularda motor liflerin reobazı ve 0.1 ms ve 1ms'deki stimulus gücü kontrol grubuna göre yüksek bulundu. Karar: Sonuçlarımız, epilepsili olguların periferik sinirlerinde aksonal eksitabilitede azalma ve dolayısıyla Na+ iletiminde olası azalmaya işaret etmektedir. Epilepside santral nöronlarda hipereksitabilite varken, periferik sinir eksitabilitesinde azalma söz konusu olabilir.Introduction: Sodium (Na+) channels have an important role for action potential formation in both central nervous system (CNS) and peripheral nervous system (PNS). The persistent Na+ current play a role in repetitive firing of action potentials caused by prolonged depolarization, thus could play a role in epilepsy. Nerve excitability measurements are made to investigate biophysical properties and disturbances of impulse conduction in peripheral axons in human subjects. Methods: In this study, it was aimed to study strength–duration properties of motor and sensory axons to evaluate whether there is a change in the current through persistent Na+ channels of sensory and motor axons in peripheral nerves of epileptic patients because of the presence of similiar channels in PNS. The study involved 17 patients newly diagnosed with partial epilepsy and 22 patients with primary generalized epilepsy who were not currently prescribed anticonvulsant therapy, and 15 control subjects. Results: Rheobase of motor fibres and stimulus strength at 0.1 ms and 1ms of motor fibres of total patients with epilepsy were higher than values of controls. Conclusions: Our results suggested a decreased axonal excitability and a possible decreased Na+ conductances in peripheral nerves in patients with epilepsy. While there is hyperexcitability of central neurons, reduced peripheral nerve excitability may be in question in epilepsy
