17β-estradiol does not have a direct effect on the function of striatal cholinergic interneurons in adult mice .

The striatum is an essential component of the basal ganglia that is involved in motor control, action selection and motor learning. The pathophysiological changes of the striatum are present in several neurological and psychiatric disorder including Parkinson's and Huntington's diseases. The striatal cholinergic neurons are the main regulators of striatal microcircuitry.

Characterization of Danube Swabian population samples on a high-resolution genome-wide basis.

Background: German-derived ethnicities are one of the largest ethnic groups in Hungary, dating back to the formation of the Kingdom of Hungary, which took place at the beginning of the 11th century. Germans arrived in Hungary in many waves. The most significant immigration wave took place following the collapse of the Ottoman Empire in East-Central Europe which closed the 150 year long Ottoman occupation.

Stereology of gonadotropin-releasing hormone and kisspeptin neurons in PACAP gene-deficient female mice.

The hypothalamic gonadotropin-releasing hormone (GnRH)-kisspeptin neuronal network regulates fertility in all mammals. Pituitary adenylate cyclase-activating polypeptide (PACAP) is a neuropeptide isolated from the hypothalamus that is involved in the regulation of several releasing hormones and trop hormones. It is well-known that PACAP influences fertility at central and peripheral levels.

Whole Exome Sequencing in a Series of Patients with a Clinical Diagnosis of Tuberous Sclerosis Not Confirmed by Targeted Sequencing.

Background: Approximately fifteen percent of patients with tuberous sclerosis complex (TSC) phenotype do not have any genetic disease-causing mutations which could be responsible for the development of TSC. The lack of a proper diagnosis significantly affects the quality of life for these patients and their families.

Methods: The aim of our study was to use Whole Exome Sequencing (WES) in order to identify the genes responsible for the phenotype of nine patients with clinical signs of TSC, but without confirmed tuberous sclerosis complex 1/ tuberous sclerosis complex 2 ( mutations using routine molecular genetic diagnostic tools.

Background/aim: Different manual therapy techniques and conservative therapy have been used separately for alleviation of pain and improvement of physical function in patients with knee osteoarthritis (KOA). However, no study has reported the effect of combination of these treatment modalities in the management of KOA. Our aim was to test the feasibility of the study design and to compare the effect of end-range Maitland mobilization to conservative therapy in KOA.

The Role of Estradiol in Traumatic Brain Injury: Mechanism and Treatment Potential.

Patients surviving traumatic brain injury (TBI) face numerous neurological and neuropsychological problems significantly affecting their quality of life. Extensive studies over the past decades have investigated pharmacological treatment options in different animal models, targeting various pathological consequences of TBI. Sex and gender are known to influence the outcome of TBI in animal models and in patients, respectively.

[A rare form of ion channel gene mutation identified as underlying cause of generalized epilepsy].

The advances in molecular genetic methods has lead to the discovery of the genetic alterations that underlie the etiology of most diseases previously held to be idiopathic. Targeted genetic examination of a pediatric male patient showing a normal intellect, an extended area of skin hypopigmentation, and suffering from generalized epilepsy displaying a switch in epilepsy syndrome during the course of the disease towards a neurocutaneous syndrome was unsuccessful. Whole-exome sequencing identified a heterozygous missense mutation in a potassium chloride cotransporter gene, which together with the phenotype underscores the diagnosis of an epilepsy syndrome known in the literature as idiopathic generalized epilepsy type 14.

[Importance of gross deletions in the diagnosis of tuberous sclerosis complex: the first Hungarian cases].

Tuberous sclerosis complex is a rare disease with high phenotypic heterogeneity, characterized by the appearance of multiplex hamartomas in the different organs. The disease is inherited by autosomal dominant manner, due to the mutations of two genes: the TSC1 or the TSC2. In this publication we present the cases of two young male and two middle-aged female patients, where pathogenetic differences of TSC1/TSC2 could not be verified by Sanger sequencing.

Marked Differences of Haplotype Tagging SNP Distribution, Linkage, and Haplotype Profile of APOA5 Gene in Roma Population Samples.

Roma people are underprivileged, neglected population worldwide, with severe healthcare problems. They have significantly increased prevalence of cardiovascular morbidity, presumably related to their poor social status, alcohol consumption and smoking habits. Assuming that genetic background also plays a role in their susceptibility for cardiovascular diseases, we hypothesized that APOA5 gene polymorphisms, an important role-player in lipid metabolism and in the development of metabolic syndrome and cardio/cerebrovascular events, may also be involved.

[De novo SCN1A gene deletion in therapy-resistant Dravet syndrome].

Severe myoclonic epilepsy in infancy (Dravet's syndrome) is a very rare form of epilepsy. Mutations of SCN1A gene encoding voltage-gated sodium channel alpha-1 subunit are major causes of the autosomal dominant disorder. Most cases are associated with a de novo point mutation, but some patients have copy number variations.

Increased prevalence of functional minor allele variants of drug metabolizing CYP2B6 and CYP2D6 genes in Roma population samples.

Background: Cytochrome P450 2B6 and 2D6 are important enzymes in human drug metabolism.

The purpose of this study was to determine the interethnic differences of four CYP1A2 drug metabolizing enzyme variants. A total of 404 Roma and 396 Hungarian healthy subjects were genotyped for -163C>A, -729C>T, -2467delT and -3860G>A variants of CYP1A2 by RT-PCR and PCR-RFLP technique. The -3860A and -729T allele were not detectable in Roma samples, while in Hungarian samples were present with 2.

Interleukins and interleukin receptors in rheumatoid arthritis: Research, diagnostics and clinical implications.

Rheumatoid arthritis (RA) is an autoimmune disease, resulting in a chronic, systemic inflammatory disorder. It may affect many tissues and organs, but it primarily affects the flexible joints. In clinical practice patient care generates many questions about diagnosis, prognosis, and treatment.

Genetic update on inflammatory factors in ulcerative colitis: Review of the current literature.

Ulcerative colitis (UC) is one of the main types of inflammatory bowel disease, which is caused by dysregulated immune responses in genetically predisposed individuals. Several genetic factors, including interleukin and interleukin receptor gene polymorphisms and other inflammation-related genes play central role in mediating and modulating the inflammation in the human body, thereby these can be the main cause of development of the disease. It is clear these data are very important for understanding the base of the disease, especially in terms of clinical utility and validity, but summarized literature is exiguous for challenge health specialist that can used in the clinical practice nowadays.

Admixture of beneficial and unfavourable variants of GLCCI1 and FCER2 in Roma samples can implicate different clinical response to corticosteroids.

Variants of glucocorticoid induced transcript 1 (GLCCI1) result decreased response to inhaled corticosteroids, while intronic variant of low-affinity IgE receptor (FCER2) is associated with exacerbation rates in children with asthma. We examined the ethnic differences, allele and genotype frequencies of two linked single nucleotide polymorphisms (rs37972, rs37973) of GLCCI1 and rs28364072 intronic variant of FCER2 gene in average Roma and Hungarian population. A study population of 474 healthy Roma and 397 Hungarian subjects were characterized for GLCCI1 and FCER2 polymorphisms using real time polymerase chain reaction (PCR) assay and PCR-restriction fragment length polymorphism method.

Diffusion tensor imaging reveals acute subcortical changes after mild blast-induced traumatic brain injury.

Mild blast-induced traumatic brain injury (mbTBI) poses special diagnostic challenges due to its overlapping symptomatology with other neuropsychiatric conditions and the lack of objective outcome measures. Diffusion tensor imaging (DTI) can potentially provide clinically relevant information toward a differential diagnosis. In this study, we aimed to determine if single and repeated (5 total; administered on consecutive days) mild blast overpressure exposure results in detectable structural changes in the brain, especially in the hippocampus.

Interleukin and interleukin receptor gene polymorphisms in inflammatory bowel diseases susceptibility.

Inflammatory bowel disease (IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC), represents a group of chronic inflammatory disorders caused by dysregulated immune responses in genetically predisposed individuals. Genetic markers are associated with disease phenotype and long-term evolution, but their value in everyday clinical practice is limited at the moment. IBD has a clear immunological background and interleukins play key role in the process.

Marked differences of haplotype tagging SNP distribution, linkage, and haplotype profile of IL23 receptor gene in Roma and Hungarian population samples.

Polymorphisms of the interleukin-23 receptor (IL23R) gene have been found to play an important role in the development of several autoimmune diseases. We examined five susceptible (rs10889677, rs1004819, rs2201841, rs11805303, rs11209032), one protective (rs7517847) and two neutral variants (rs7530511, rs1884444) of the IL23R gene in pooled DNA of healthy Roma (Gipsy) and Hungarian population samples. Our aim was to determine the genetic variability of the major haplotype tagging polymorphisms, and the haplotype profile of IL23R between the two groups.

[Novel TSC1 mutation associated with variable phenotypes in tuberous sclerosis].

Tuberous sclerosis is an autosomal dominant disorder, caused by mutations of the TSC1 or TSC2 genes resulting in tumor predisposition. Clinical signs include non-malignant brain tumors, skin, eye, heart and kidney abnormalities. The authors report a Hungarian family with broad phenotypic variability.

Long-term consequences of single and multiple mild blast exposure on select physiological parameters and blood-based biomarkers.

Mild traumatic brain injury (mTBI), especially when it is repeated (rmTBI), can lead to progressive degenerative diseases and lasting neuropsychiatric abnormalities. To better understand the long-term pathobiological changes in mTBI and rmTBI, we exposed rats to single or repeated (5 total; administered on consecutive days) mild blast overpressure, monitored changes in physiological parameters, and determined the plasma levels of select biomarkers at 42 days post injury by proteomics. We unexpectedly found comparable changes in arterial oxygen saturation levels and heart rates of single-injured (SI) and multiple-injured (MI) rats throughout the observation period.

Neurobehavioral, cellular, and molecular consequences of single and multiple mild blast exposure.

Mild traumatic brain injury, caused by the exposure to single or repeated blast overpressure, is a principal concern due to its pathological complexity and neurobehavioral similarities with posttraumatic stress disorder. In this study, we exposed rats to a single or multiple (five total; administered on consecutive days) mild blasts, assessed their behavior at 1 and 16 days postinjury) and performed histological and protein analyses of brains and plasma at an early (2 h) and a late (22 days) termination time point. One day postinjury, multiple-injured (MI) rats showed the least general locomotion and the most depression- and anxiety-related behaviors among the experimental groups; there were no such differences at 16 days.

Effect of PACAP in central and peripheral nerve injuries.

Pituitary adenylate cyclase activating polypeptide (PACAP) is a bioactive peptide with diverse effects in the nervous system. In addition to its more classic role as a neuromodulator, PACAP functions as a neurotrophic factor. Several neurotrophic factors have been shown to play an important role in the endogenous response following both cerebral ischemia and traumatic brain injury and to be effective when given exogenously.

Acute minocycline treatment mitigates the symptoms of mild blast-induced traumatic brain injury.

Mild traumatic brain injury (mTBI) represents a significant challenge for the civilian and military health care systems due to its high prevalence and overall complexity. Our earlier works showed evidence of neuroinflammation, a late onset of neurobehavioral changes, and lasting memory impairment in a rat model of mild blast-induced TBI (mbTBI). The aim of our present study was to determine whether acute treatment with the non-steroidal anti-inflammatory drug minocycline (Minocin(®)) can mitigate the neurobehavioral abnormalities associated with mbTBI, Furthermore, we aimed to assess the effects of the treatment on select inflammatory, vascular, neuronal, and glial markers in sera and in brain regions associated with anxiety and memory (amygdala, prefrontal cortex, ventral, and dorsal hippocampus) following the termination (51 days post-injury) of the experiment.
