Suckling induced activation pattern in the brain of rat pups.

Objectives: The aim of the study was to understand the effects of suckling on the brain of the pups by mapping their brain activation pattern in response to suckling.

Methods: The c-fos method was applied to identify activated neurons. Fasted rat pups were returned to their mothers for suckling and sacrificed 2 hours later for Fos immunohistochemistry.

Suppression of tumor growth by a heterologous antibody directed against multiple myeloma dominant CD38 antigen in SCID mice injected with multiple myeloma cells.

Employing passive immunization - using a heterologous anti-CD38 IgG antibody containing serum - in SCID mice injected subcutaneously with human multiple myeloma cells, we have shown that treatments with the antiserum - especially in the presence of complement - significantly decreased cancer growth. However, administered antibody and complement was not sufficient in amount to prevent cancer cell multiplication and cancer growth expansion to a satisfactory degree. Larger volumes of the same components more than likely would have further reduced cancer growth and prolonged the life of mice.

Capillary electrophoresis analysis of N-glycosylation changes of serum paraproteins in multiple myeloma.

Multiple myeloma (MM) is an immedicable malignancy of the human plasma cells producing abnormal antibodies (also referred to as paraproteins) leading to kidney problems and hyperviscosity syndrome. In this paper, we report on the N-glycosylation analysis of paraproteins from total human serum as well as the fragment crystallizable region (F ) and fragment antigen binding (F ) κ/λ light chain fractions of papain digested immunoglobulins from multiple myeloma patients. CE-LIF detection was used for the analysis of the N-glycans after endoglycosidase (PNGase F) mediated sugar release and fluorophore labeling (APTS).

Shuttling along DNA and directed processing of D-loops by RecQ helicase support quality control of homologous recombination.

Cells must continuously repair inevitable DNA damage while avoiding the deleterious consequences of imprecise repair. Distinction between legitimate and illegitimate repair processes is thought to be achieved in part through differential recognition and processing of specific noncanonical DNA structures, although the mechanistic basis of discrimination remains poorly defined. Here, we show that Escherichia coli RecQ, a central DNA recombination and repair enzyme, exhibits differential processing of DNA substrates based on their geometry and structure.

Absence epileptic activity in Wistar Albino Glaxo Rijswijk rat mothers.

Absence epileptic activity was analyzed during pregnancy, the postpartum period and after weaning to establish alterations of seizures throughout the reproductive cycle. Wistar Albino Glaxo Rijswijk (WAG/Rij) rats were used in the study as a model of absence epilepsy and because their seizures do not interfere with rearing offspring. The number of spike-wave discharges (SWDs) was gradually elevated from the 19th pregnancy day to delivery.

Exogenous Ketone Supplements Reduce Anxiety-Related Behavior in Sprague-Dawley and Wistar Albino Glaxo/Rijswijk Rats.

Nutritional ketosis has been proven effective for seizure disorders and other neurological disorders. The focus of this study was to determine the effects of ketone supplementation on anxiety-related behavior in Sprague-Dawley (SPD) and Wistar Albino Glaxo/Rijswijk (WAG/Rij) rats. We tested exogenous ketone supplements added to food and fed chronically for 83 days in SPD rats and administered sub-chronically for 7 days in both rat models by daily intragastric gavage bolus followed by assessment of anxiety measures on elevated plus maze (EPM).

Disrupting the blood-brain barrier by focused ultrasound induces sterile inflammation.

MRI-guided pulsed focused ultrasound (pFUS) combined with systemic infusion of ultrasound contrast agent microbubbles (MB) causes localized blood-brain barrier (BBB) disruption that is currently being advocated for increasing drug or gene delivery in neurological diseases. The mechanical acoustic cavitation effects of opening the BBB by low-intensity pFUS+MB, as evidenced by contrast-enhanced MRI, resulted in an immediate damage-associated molecular pattern (DAMP) response including elevations in heat-shock protein 70, IL-1, IL-18, and TNFα indicative of a sterile inflammatory response (SIR) in the parenchyma. Concurrent with DAMP presentation, significant elevations in proinflammatory, antiinflammatory, and trophic factors along with neurotrophic and neurogenesis factors were detected; these elevations lasted 24 h.

NMDA-receptor associated encephalitis in a woman with mature cystic ovarian teratoma.

Introduction - N-methyl-D-aspartate receptor (NMDA-R) antibody-associated encephalitis has been reported in the international neurological literature to be associated with mature or immature ovarian teratomas (OTs). However, few cases of encephalitis were diagnosed in Hungary. In 2011 Hollody et al.

Production cross sections of radioisotopes from He-particle induced nuclear reactions on natural titanium.

Excitation functions were measured using the stacked-foil method for the Ti(He,x)Sc, Sc, Sc, Sc, V and Cr nuclear processes up to 68MeV. Our new cross-section data were compared with the earlier reported values as well as the evaluated theoretical predictions by means of the TALYS 1.6 code as compiled in the TENDL-2015 library.

Physico-chemical properties of Mn complexes formed with cis- and trans-DO2A: thermodynamic, electrochemical and kinetic studies.

Mn complexes formed with cis- and trans-DO2A (DO2A=1,4,7,10-tetraazacyclododecane-1,4 (or 1,7) -diacetic acid) chelators were investigated by pH-potentiometry, H relaxometry, UV-vis spectrophotometry and cyclic voltammetry. The physico-chemical characteristics of Mn complexes of these structure isomers do not differ dramatically, however the cis-DO2A platform has better potential for further development. Manganese (Mn) is a promising alternative to gadolinium (Gd) as a magnetic resonance imaging (MRI) agent.

Plasma mirrors for short pulse KrF lasers.

It is demonstrated for the first time that plasma mirrors can be successfully applied for KrF laser systems. High reflectivity up to 70% is achieved by optimization of the beam quality on the plasma mirror. The modest spectral shift and the good reflected beam quality allow its applicability for high power laser systems for which a new arrangement is suggested.

Systematic review of the old and new concepts in the epithelial-mesenchymal transition of colorectal cancer.

Epithelial-to-mesenchymal transition (EMT) is defined as the transformation of an epithelial cell into a spindle cell with the loss of membrane E-cadherin expression and the gain of mesenchymal markers positivity. In the field of colorectal cancer (CRC), first data about EMT was published in 1995 and more than 400 papers had been written up to March 2016. Most of them are focused on the molecular pathways and experimentally-proved chemoresistance.

Physicochemical characterization of ferumoxytol, heparin and protamine nanocomplexes for improved magnetic labeling of stem cells.

Stem cell-based therapies have become a major focus in regenerative medicine and to treat diseases. A straightforward approach combining three drugs, heparin (H), protamine (P) with ferumoxytol (F) in the form of nanocomplexes (NCs) effectively labeled stem cells for cellular MRI. We report on the physicochemical characteristics for optimizing the H, P, and F components in different ratios, and mixing sequences, producing NCs that varied in hydrodynamic size.

Charting the chemical space around the (iso)indoline scaffold, a comprehensive approach towards multitarget directed ligands.

Within the framework of orthosteric G protein coupled receptor (GPCR) polypharmacology herein we report the systematic elaboration and thorough evaluation of a data matrix generated by sampling the chemical space around a common 5,6-fused bicyclic heteroaromatic template applying characteristic pharmacophore elements of central nervous system (CNS) relevant aminergic GPCR ligands.

Resin-bonded fixed dental prosthesis with a modified treatment surface in a zirconia framework: a case report.

Although resin-bonded fixed dental prostheses (RBFDPs) were developed almost 40 years ago, their implementation in clinical practice did not achieve success due to biomechanical failures of the restorative materials. Nowadays, the evolution of ceramic materials and bonding procedures has allowed for the revival of the dental prosthesis. Zirconia is the dental ceramic with the highest flexural strength under compression.

Smart Sensing System for the Prognostic Monitoring of Bone Health.

The objective of this paper is to report a novel non-invasive, real-time, and label-free smart assay technique for the prognostic detection of bone loss by electrochemical impedance spectroscopy (EIS). The proposed system incorporated an antibody-antigen-based sensor functionalization to induce selectivity for the C-terminal telopeptide type one collagen (CTx-I) molecules-a bone loss biomarker. Streptavidin agarose was immobilized on the sensing area of a silicon substrate-based planar sensor, patterned with gold interdigital electrodes, to capture the antibody-antigen complex.

Separation window dependent multiple injection (SWDMI) for large scale analysis of therapeutic antibody N-glycans.

There is a growing demand in the biopharmaceutical industry for large scale N-glycosylation analysis of biotherapeutics, especially monoclonal antibodies. To fulfill this high throughput analysis requirement with single column separation systems in most instances require finishing the entire analysis cycle including conditioning, injection and separation between sample injections. While in liquid chromatography it represents a challenge, multiple sample injection in capillary electrophoresis has already been demonstrated for one or two sample components by utilizing the concept of introducing sequential sample and buffer zones into the capillary tubing before the start of the separation process.

Guanosine may increase absence epileptic activity by means of A2A adenosine receptors in Wistar Albino Glaxo Rijswijk rats.

The non-adenosine nucleoside guanosine (Guo) was demonstrated to decrease quinolinic acid(QA)-induced seizures, spontaneously emerged absence epileptic seizures and lipopolysaccharide(LPS)-evoked induction of absence epileptic seizures suggesting its antiepileptic potential. It was also described previously that intraperitoneal (i.p.

TOX3 regulates neural progenitor identity.

The human genomic locus for the transcription factor TOX3 has been implicated in susceptibility to restless legs syndrome and breast cancer in genome-wide association studies, but the physiological role of TOX3 remains largely unknown. We found Tox3 to be predominantly expressed in the developing mouse brain with a peak at embryonic day E14 where it co-localizes with the neural stem and progenitor markers Nestin and Sox2 in radial glia of the ventricular zone and intermediate progenitors of the subventricular zone. Tox3 is also expressed in neural progenitor cells obtained from the ganglionic eminence of E15 mice that express Nestin, and it specifically binds the Nestin promoter in chromatin immunoprecipitation assays.

Hepatic gluconeogenesis influences (13)C enrichment in lactate in human brain tumors during metabolism of [1,2-(13)C]acetate.

(13)C-enriched compounds are readily metabolized in human malignancies. Fragments of the tumor, acquired by biopsy or surgical resection, may be acid-extracted and (13)C NMR spectroscopy of metabolites such as glutamate, glutamine, 2-hydroxyglutarate, lactate and others provide a rich source of information about tumor metabolism in situ. Recently we observed (13)C-(13)C spin-spin coupling in (13)C NMR spectra of lactate in brain tumors removed from patients who were infused with [1,2-(13)C]acetate prior to the surgery.

Oxidative Conversion of a Europium(II)-Based T1 Agent into a Europium(III)-Based paraCEST Agent that can be Detected In Vivo by Magnetic Resonance Imaging.

The Eu(II) complex of 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) tetra(glycinate) has a higher reduction potential than most Eu(II) chelates reported to date. The reduced Eu(II) form acts as an efficient water proton T1 relaxation reagent, while the Eu(III) form acts as a water-based chemical exchange saturation transfer (CEST) agent. The complex has extremely fast water exchange rate.
