Neuroepigenetics is a new emerging field, mainly focusing on epigenetic mechanism study of the central nervous system (CNS). New discoveries show that the CNS-related behaviors, CNS disorders, neural plasticity, neurotoxicity, drug addiction and other neurological disorders are related to the underlying epigenetic mechanisms. Moreover, the development and the function of the human nervous syste...

sarcoidosis is a multisystem noncaseating granulomatous disease with a propensity for lung, eye, and skin which recently have been proposed that mycobacterium tuberculosis may contribute in its pathogenesis, and rarely involves central nervous system (cns). despite cd4+ lymphocytopenia, sarcoidosis by itself does not increase risk of opportunistic infections other than cryptococcosis.nonetheles...

Bone morphogenetic protein 9 (BMP9), also known as growth differentiation factor 2 (GDF2), is a member of the transforming ? (TGF ?) superfamily. Although BMP9 plays pivotal roles during development, including angiogenesis, hematopoiesis, hepatogenesis, osteogenesis, and glucose metabolism, little information available for expression in central nervous system (CNS). We, thus, investigated adult...

Gliomas are the most common neoplastic tumours of the central nervous system. The aim of the study was to evaluate the proliferative activity of chosen types of gliomas and to analyse their correlation with histological type, malignancy grade, location, size and clinical symptoms. The study involved patients with astrocytoma, anaplastic astrocytoma, glioblastoma, oligodendroglioma, anaplastic o...

The CNS (central nervous system) is unquestionably the central organ that regulates directly or indirectly all physiological systems in the mammalian body. Yet, when considering the defence of the CNS from pathogens, the CNS has often been considered passive and subservient to the pro-inflammatory responses of the immune system. In this view, neuroinflammatory disorders are examples of when the...

Background: Tumors of the central nervous system (CNS) are a heterogeneous group of neoplasms with different prevalence in different sex and age groups and various parts of CNS. Objectives: Determining the relative frequency of different types of CNS tumors in different ages, sex and CNS anatomical locations. Materials and Methods: This retrospective study was performed using pathological repor...

Background: Central Nervous System (CNS) relapse in acute lymphoblastic leukemia was significantly decreased due to the use of new chemotherapyeutic agents, Intrathecal chemotherapy and cranial irradiation. The purpose of this study was to compare the effectiveness of intrathecal (IT) CNS chemotherapy alone versus combination of IT chemotherapy with cranial irradiation for prevention of CNS rel...

Besides being a metabolite of nucleotides like ATP, adenosine is a mediator of neuronal function in the central nervous system. Its actions are mediated by at least three extracellular receptors. In this review different aspects of adenosine such as biosynthesis, release, inactivation and its receptors are discussed. It also covers pre- and postsynaptic effects as well as postreceptor mecha...

Alzheimer’s disease (AD) is a neurodegenerative disease that is the most common type of dementia.AD includes 60_80% of dementia and most people with AD have more than 65 years old.AD causes losing neuronal activity by abnormal proteins. Plaques of beta-amyloid and tangles of “tau” protein can lead to AD. Recently evidence has found that AD may come from outside of central nerv...

Tuberculosis is a formidable disease worldwide because of its highly infectious nature and propensity for latency. The increasing prevalence of tuberculosis in both immunocompetent and immunocompromised individuals in recent years makes this disease a topic of universal concern. The disease has insidious onset and can affect virtually any organ system in the body, including the central nervous ...
