Controlling the anisotropy of a van der Waals antiferromagnet with light
2020
Ultrafast optical control of magnetic anisotropy in a van der Waals antiferromagnet activates a sub-THz two-dimensional magnon.
First Cobalt(II) Spin Crossover Compound with N4S2-Donorset
2020
Herein we report the synthesis and characterization of a novel bis-tridentate 1,3,4-thiadiazole ligand (L = 2,5-bis[(2-pyridylmethyl)thio]methyl-1,3,4-thiadiazole). Two new mononuclear complexes of the type [MII(L)2](ClO4)2 (with M = FeII (C1) and CoII (C2)) have been synthesized, containing the new ligand (L). In both complexes the metal centers are coordinated by an N4S2-donorset and each of the two ligands is donating to the metal ion with just one of the tridentate pockets. The iron(II) complex (C1) is in the low spin [LS] state below room temperature and shows an increase in the magnetic moment only above 300 K. In contrast, the cobalt(II) complex (C2) shows a gradual spin crossover (S…
Microsomal triglyceride transfer protein gene mutations in Turkish children: A novel mutation and clinical follow up.
2016
Abetalipoproteinemia (ABL; OMIM 200100) is a rare autosomal recessive disease that affects the absorption of dietary fats and fat soluble vitamins. Here, we describe the clinical and genetic characteristics of three patients with ABL. Two patients (patients 1 and 2) who were carriers of the c.398-399delAA mutation (previously known mutation) had developmental delay and hepatic steatosis developed at the age of five in patient 1. Patient 3 was the carrier of a novel mutation (g.10886-10902delAAGgtaagtttgtgttg in intron 3 and c.506A>T exon 5) in microsomal triglyceride transfer protein (MTP) gene and had hepatic steatosis.
New neurons use Slit-Robo signaling to migrate through the glial meshwork and approach a lesion for functional regeneration

Appropriate positioning of new neurons in the brain promotes post-stroke functional recovery.
Testing safety of germinated rye sourdough in a celiac disease model based on the adoptive transfer of prolamin-primed memory T cells into lymphopeni…
2014
The current treatment for celiac disease is strict gluten-free diet. Technical processing may render gluten-containing foods safe for consumption by celiac patients, but so far in vivo safety testing can only be performed on patients. We modified a celiac disease mouse model to test antigenicity and inflammatory effects of germinated rye sourdough, a food product characterized by extensive prolamin hydrolysis. Lymphopenic Rag1−/− or nude mice were injected with splenic CD4+CD62L−CD44high-memory T cells from gliadin- or secalin-immunized wild-type donor mice. We found that: 1) Rag1−/− recipients challenged with wheat or rye gluten lost more body weight and developed more severe histological…
Time-dependence and differential induction of rat and guinea pig peroxisomal beta-oxidation, palmitoyl-CoA hydrolase, cytosolic and microsomal epoxid…
1988
Fischer-344 rats and Hartley guinea pigs received a diet containing 0.01% (w/w), 0.05% (w/w), or 0.25% (w/w) of the hypolipidemic drug fenofibrate. Rats were treated for 4, 7, 14, or 21 days, and a clear dose-dependent and weak time-dependent increase in liver/body weight ratio was observed. The specific activity of peroxisomal beta-oxidation increased linearly with time at all concentrations used. A dose-dependent increase in cEH was observed, but the activity remained constant after treatment for 7 days. Enhancement of palmitoyl-CoA hydrolase was dose-dependent, but was similar at all 4 time points investigated. In contrast to the other enzyme activities, mEH was not or only minimally (le…
Intravitreal therapies for non-neovascular age-related macular degeneration with intraretinal or subretinal fluid
2017
OBJECTIVE: To evaluate the efficacy of intravitreal therapies in cases of atrophic age-related macular degeneration (AMD) with subretinal or intraretinal fluid. METHODS: A retrospective review was made of the clinical charts of patients diagnosed with atrophic AMD with subretinal or intraretinal fluid. Fundus photographs and spectral-domain optical coherence tomography images were examined, and an analysis was made on the presence of fluid and its density. Neovascularisation was ruled out by fluorescein and/or indocyanine green angiography. RESULTS: The study included 14 eyes from 13 patients with a mean age of 72.64 years and a mean follow-up of 80.5 weeks. Intraretinal fluid was observed …
Visualization of a covalent intermediate between microsomal epoxide hydrolase, but not cholesterol epoxide hydrolase, and their substrates
1997
Mammalian soluble and microsomal epoxide hydrolases have been proposed to belong to the family of alpha/beta-hydrolase-fold enzymes. These enzymes hydrolyse their substrates by a catalytic triad, with the first step of the enzymatic reaction being the formation of a covalent enzyme-substrate ester. In the present paper, we describe the direct visualization of the ester formation between rat microsomal epoxide hydrolase and its substrate. Microsomal epoxide hydrolase was precipitated with acetone after brief incubation with [1-(14)C]epoxystearic acid. After denaturing SDS gel electrophoresis the protein-bound radioactivity was detected by fluorography. Pure epoxide hydrolase and crude micros…
International Olympic Committee (IOC) Consensus Statement on Relative Energy Deficiency in Sport (RED-S): 2018 Update
2018
In 2014, the International Olympic Committee (IOC) published a consensus statement entitled “Beyond the Female Athlete Triad: Relative Energy Deficiency in Sport (RED-S)”. The syndrome of RED-S refers to: “impaired physiological functioning caused by relative energy deficiency, and includes but is not limited to impairments of metabolic rate, menstrual function, bone health, immunity, protein synthesis, and cardiovascular health.”
Evidence of Transient IgA Anti-Endomysial Antibody Positivity in a Patient with Graves’ Disease
1999
<i>Background:</i> Anti-endomysial antibodies (EmA) have been shown to have a high specificity and sensitivity in celiac disease (CD) diagnosis, and their use is considered effective in improving the diagnostic accuracy of CD screening. <i>Aims:</i> To report the clinical details of transient IgA EmA positivity in a patient with Graves’ disease. <i>Methods:</i> We screened 48 patients (7 males, age range 19–79, median 58.3 years) for CD. They were hospitalized for thyroid disorders (30 patients had autoimmune hypothyroidism and 18 had Graves’ disease with clinical hyperthyroidism associated with diffuse goitre). CD screening was carried out on all patient…
