Phase-dependent suppression of beta oscillations in Parkinson's disease patients.

J Neurosci 2018 Dec 14. Epub 2018 Dec 14.

MRC Brain Network Dynamics Unit, Department of Pharmacology, University of Oxford, Oxford OX1 3TH, United Kingdom

Synchronized oscillations within and between brain areas facilitate normal processing, but are often amplified in disease. A prominent example is the abnormally sustained beta-frequency (∼20Hz) oscillations recorded from the cortex and subthalamic nucleus of Parkinson's disease patients. Computational modelling suggests that the amplitude of such oscillations could be modulated by applying stimulation at a specific phase. Read More

Lymphatic Vascular Structures: A New Aspect in Proliferative Diabetic Retinopathy.

Int J Mol Sci 2018 Dec 13;19(12). Epub 2018 Dec 13.

Research Programs Unit, Genome-Scale Biology, Biomedicum Helsinki, University of Helsinki, FI-00014 Helsinki, Finland.

Diabetic retinopathy (DR) is the most common diabetic microvascular complication and major cause of blindness in working-age adults. According to the level of microvascular degeneration and ischemic damage, DR is classified into non-proliferative DR (NPDR), and end-stage, proliferative DR (PDR). Despite advances in the disease etiology and pathogenesis, molecular understanding of end-stage PDR, characterized by ischemia- and inflammation-associated neovascularization and fibrosis, remains incomplete due to the limited availability of ideal clinical samples and experimental research models.

Hyperglycemia invoke number of pathways resulting in development of diabetic retinopathy (DR), including protein kinase C activation, increased expression of VEGF, advanced glycation end product (AGEs) formation and activation of polyol pathway, among which the pathophysiology of aldose reductase (ALR2) of the polyol pathway is evident by more than a decade of research. Subtle involvement of ALR2 in invoking various pathways of diabetic complications has caused an increase in attention towards the identification of novel aldose reductase inhibitors (ARIs). Numerous ARIs of different classes were employed in the treatment of diabetic complications initially, but few came into light as drugs. Read More

According to phylogenetic theory of general pathology, when living in ocean all were carnivorous (piscivorous) fatty acids transferring to cells in form of non-polar triglycerides nitially began apoB-48 chylomicrons, continued lipoproteins of very low and low density and fnalized its apoB-100 endocytosis. The fatty acids are transferred by chylomicrons + lipoproteins of very low density + lipoproteins of low density and non-polar triglycerides are hydrolyzed by hepatic glycerolhydrogenase and co-enzyme apoC-III; according WHO classifcation, hyperlipoproteinemia corresponds to type V. On land, in herbivorous who are not yet synthesized insulin, apoB-48 and chylomicrons left process of non-polar triglycerides transferring. Read More

A Double-Blind, Randomized, Placebo-Controlled Study of Aspirin and N-Acetylcysteine as Adjunctive Treatments for Bipolar Depression.

J Clin Psychiatry 2018 Dec 4;80(1). Epub 2018 Dec 4.

Department of Psychiatry and Behavioral Sciences, University of Texas Health Science Center at Houston, McGovern Medical School, Houston, Texas, USA.

Objective: Neuroinflammation has been implicated in the pathophysiology of bipolar disorder. Some evidence shows that nonsteroidal anti-inflammatory drugs (NSAIDs) have promising antidepressant effects. The antioxidant N-acetylcysteine (NAC) may enhance the effects of NSAIDs. Read More

Acid Sensing Ion Channel 2: a new potential player in the pathophysiology of multiple sclerosis.

Eur J Neurosci 2018 Dec 14. Epub 2018 Dec 14.

Department of Brain and Behavioral Sciences, University of Pavia, Pavia, Italy.

Acid Sensing Ion Channel (ASICs) are proton-gated channels involved in multiple biological functions such as: pain modulation, mechanosensation, neurotransmission and neurodegeneration. Earlier, we described the genetic association, within the Nuoro population, between multiple sclerosis (MS) and rs28936, located in ASIC2 3'UTR. Here we investigated the potential involvement of ASIC2 in MS inflammatory process. Read More

Identification of potential prognostic TF-associated lncRNAs for predicting survival in ovarian cancer.

J Cell Mol Med 2018 Dec 13. Epub 2018 Dec 13.

The First Affiliated Hospital, Harbin Medical University, Harbin, China.

The pathophysiology of ovarian cancer (OV) is complex and depends on multiple biological processes and pathways. Therefore, there is an urgent need to identify reliable prognostic biomarkers for predicting clinical outcomes and helping personalize treatment of OV. A long non-coding RNA (lncRNA)-based risk score model was constructed to infer the prognostic efficacy of transcription factors (TFs) based on the OV dataset from The Cancer Genome Atlas. Read More

Dysfunctional endothelial progenitor cells in patients with Hodgkin's lymphoma in complete remission.

Cancer Med 2018 Dec 13. Epub 2018 Dec 13.

Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel.

Background: Patients with a history of Hodgkin's lymphoma (HL) are at increased long-term risk of cardiovascular morbidity and mortality. Studies report an association between the pathophysiology of coronary artery disease (CAD) and levels of circulating endothelial progenitor cells (EPC), which play an essential role in vascular injury repair. The aim of the present study was to investigate the potential involvement of abnormal EPC level or function in the CAD risk of survivors of HL in remission. Read More

Review of rodent hypertensive glaucoma models.

Acta Ophthalmol 2018 Dec 13. Epub 2018 Dec 13.

Department of Ophthalmology & Visual Sciences, Chinese University of Hong Kong, Hong Kong, Hong Kong.

Glaucoma is a neurodegenerative disease characterized by the progressive loss of retinal ganglion cells (RGCs). Elevated intraocular pressure (IOP) is a primary risk factor for the development and progression of glaucoma. Rodent models of glaucoma have greatly improved our understanding of the pathophysiology of glaucoma and served as a useful tool to investigate neuroprotective agents. Read More

Enkephalinase inhibitors, potential therapeutics for the future treatment of diarrhea predominant functional gastrointestinal disorders.

Neurogastroenterol Motil 2018 Dec 14:e13526. Epub 2018 Dec 14.

Department of Biochemistry, Faculty of Medicine, Medical University of Lodz, Lodz, Poland.

The endogenous opioid system (EOS) is considered being a crucial element involved in the pathophysiology of irritable bowel syndrome (IBS) as it regulates gastrointestinal (GI) homeostasis through modulation of motility and water and ion secretion/absorption. Along with opioid receptors (ORs), the following components of EOS can be distinguished: 1. endogenous opioid peptides (EOPs), namely enkephalins, endorphins, endomorphins and dynorphins, and 2.

Tetrasomy 18p: The challenges of noninvasive prenatal testing and combined test.

J Obstet Gynaecol Res 2018 Dec 13. Epub 2018 Dec 13.

Pediatric Highly Intensive Care Unit, Department of Pathophysiology and Transplantation, Università degli Studi di Milano, Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, Milan, Italy.

Circulating cell-free DNA, having no procedural risk of miscarriage, is the most suitable sample for a noninvasive prenatal testing (NIPT). Here we report on a boy, who came to our attention for hypotonia and psychomotor delay when he was 16 months old. During the pregnancy his mother performed a NIPT that resulted compatible with the presence of trisomy 18. Read More
