Differential regulation of mRNAs for nerve growth factor, brain-derived neurotrophic factor, and neurotrophin 3 in the adult rat brain following cerebral ischemia and hypoglycemic coma

In situ hybridization was used to study expression of mRNAs for members of the nerve growth factor (NGF) family in the rat brain after 2 and 10 min of forebrain ischemia and 1 and 30 min of insulin-induced hypoglycemic coma. Two hours after the ischemic insults, the level of brain-derived neurotrophic factor (BDNF) mRNA was markedly increased in the granule cells of the dentate gyrus, and at 24 h

Increased levels of messenger RNAs for neurotrophic factors in the brain during kindling epileptogenesis

Kindling, induced by repeated subconvulsive electrical or chemical stimulations leads to progressive and permanent amplification of seizure activity, culminating in generalized seizures. We report that kindling induced by electrical stimulation in the ventral hippocampus leads to a marked and transient increase of mRNA for NGF and BDNF in the dentate gyrus, the parietal cortex, and the piriform co

Inversion of the early component of IPSPs in neurons of the sensorimotor cortex by artificial hyperpolarization of the membrane was demonstrated in cats immobilized by myorelaxants in acute experiments. The late component of IPSP was not inverted. Amplitudes of the early component of IPSPs were decreased by the membrane depolarization while the late component was completely reduced. The input resi

Inversion of the early component of IPSPs in pyramidal neurons of the sensorimotor cortex by intracellular injection of chloride ions was demonstrated in cats immobilized by myorelaxants in acute experiments under moderate composed anesthesia (40 mg/kg nembutal and 20 mg/kg chloralose intraperitoneally). The late component of IPSPs as well as the post-burst hyperpolarization in pyramidal neurons w

Negotiating Heresy : The Reception of Origen in Jerome's Eschatological Thought

The aim of this study is to examine the reception of Origen of Alexandria (185-253/54) in the eschatological thought ofJerome of Stridon (347-419/20). Jerome, who was a Christian ascetic writer and a biblical commentator, relied heavily on Origen’s works during the first part of his career. Due to the Origenist controversy, which took place in the 390s and was initiated by Bishop Epiphanius of Sal

Spectral Signatures in the Different Layers of the Human Eyelid by Photoacoustic Imaging

BACKGROUND AND OBJECTIVES: The eyelids are susceptible to a number of skin cancers, which are challenging to excise radically without sacrificing excessive healthy tissue. Photoacoustic (PA) imaging is an emerging non-invasive biomedical imaging modality that could potentially be used for intraoperative micrographic control of the surgical margins of eyelid tumors. In this study, non-cancerous hum

Complex state ownership, competition, and firm performance – Russian evidence

Purpose: State ownership has been common especially in industries with restricted competition. In Russia, state-controlled firms represent around 41 percent of the market value of all listed firms (Deloitte, 2015). Yet, there is a significant gap in the literature regarding the effects of various forms of government control in listed firms. The purpose of this paper is to fill this gap by explorin

Lost in Translation? Care Coordination cross Contexts in Swedish Homecare Nursing

The responsibilities for delivery of care in Sweden is divided between the regions and the municipalities. The regions run the hospitals and the primary care centres (PCCs) whereas the municipalities are responsible for homecare nursing and nursing homes. The homecare nurses and the doctors they need to seek advice from, thus belong to different organizations/contexts. As more patients with multi-

Seeding of protein aggregation causes cognitive impairment in rat model of cortical synucleinopathy

Background: Cortical α-synuclein pathology plays a role in the development of cognitive dysfunction in both Parkinson's disease and dementia with Lewy bodies, although the causative cellular lesions have remained unclear. We aimed to address causal links between α-synuclein-driven pathology in the cerebral cortex and the development of cognitive impairments using new experimental models. Methods:

Prevalence and goal attainment with spinal orthoses for children with cerebral palsy

PURPOSE: Analyze the goals for treatment and attained goals for spinal orthoses in children with cerebral palsy (CP), and describe the use of spinal orthoses in relation to age, sex, gross motor function, and scoliosis. METHODS: Cross-sectional data for all children born between 2000 and 2014 and registered in the Swedish CP registry were analyzed in relation to age, sex, Gross Motor Function Clas

Collaborative tourism-making : an interdisciplinary review of co-creation and a future research agenda

For some time, tourism researchers have sought to examine and theorise types of collaborative exchange and the characteristics of relational work in tourism. Different ontological and epistemological framings, and associated language games have contributed to a fragmented body of knowledge. In this paper, we argue that the new term ‘co-creation’ is part of this language game, and efforts to date h

Using X-ray tomoscopy to explore the dynamics of foaming metal

The complex flow of liquid metal in evolving metallic foams is still poorly understood due to difficulties in studying hot and opaque systems. We apply X-ray tomoscopy –the continuous acquisition of tomographic (3D) images– to clarify key dynamic phenomena in liquid aluminium foam such as nucleation and growth, bubble rearrangements, liquid retraction, coalescence and the rupture of films. Each ph

Non-voluntary service interaction from a service logic perspective : children and value co-creation

Public sector services are complex in relation to many private sector services. For example, public sector services contain non-voluntary service interaction. This area of practice has not been extensively researched to date. In this article, we explore and discuss service interaction in public non-voluntary services targeting children, in order to understand what elements go into value co-creatio

Familial Clustering, Second Primary Cancers and Causes of Death in Penile, Vulvar and Vaginal Cancers

Data on familial risks in penile and vulvar/vaginal cancers and in second primary cancers (SPCs) following these cancers are limited. We used the Swedish Family-Cancer Database from years 1958 through 2015 to identify 3641 penile and 8856 vulvar/vaginal cancers and to calculate relative risks (RRs) and 95% confidence intervals (CIs) for these cancers according to site-specific cancer in family mem

Class Id ribonucleotide reductase utilizes a Mn2(IV,III) cofactor and undergoes large conformational changes on metal loading

Outside of the photosynthetic machinery, high-valent manganese cofactors are rare in biology. It was proposed that a recently discovered subclass of ribonucleotide reductase (RNR), class Id, is dependent on a Mn2(IV,III) cofactor for catalysis. Class I RNRs consist of a substrate-binding component (NrdA) and a metal-containing radical-generating component (NrdB). Herein we utilize a combination of

Oxidation-reduction potential (ORP) as a tool for process monitoring of H2O2/LPMO assisted enzymatic hydrolysis of cellulose

Oxidation-reduction potential (ORP) is an environmental factor of importance in several biological conversion processes. Lytic polysaccharide monooxygenases (LPMOs) catalyze oxidative disruption of the cellulose chain in the presence of oxygen or hydrogen peroxide and increase enzymatic hydrolysis yields. However, the enzymes are also sensitive to oxidative damage and the level of oxidative agent
