Determination of vitamin B9 levels in the milk of Brown Swiss and Simmental cows using the ELISA method

The aim of this study was to determine the levels of folic acid in Brown Swiss and Simmental cows’ milk by the competitive ELISA method. Brown Swiss and Simmental cows’ milk samples were collected from two dairies between  February and August 2017 (20 samples from Brown Swiss and 22 samples  from Simmental). The average level of vitamin B9 in Brown Swiss milk was approximately 3.27 ± 1.23 μg/100 g, while for Simmental it was around 2.99 ± 0.88 μg/100 g. In the milk mixture, the mean folic acid level was 3.13 ± 1.07 μg/100 g. There was no statistical difference between breeds in terms of folic acid levels in cow's milk. It was concluded that milk is not a sufficient source to meet the daily folic acid needs of adults in Turkey.Keywords: Dairy cattle breeds, folic acid, raw mil

Untersuchung der auswirkung von injektionsanästhesie mit propofol über die hämatologische und biochemische parameter bei den katzen

Ziel der vorliegenden Studie soll es sein, die Kombinationen von Ketamin/Diazepam/Propofol hinsichtlich ihrer Wirkungen und Nebenwirkungen bei der Katze zu untersuchen. Für das Versuchsvorhaben wurden insgesamt 12 Katzen eingesetzt. In der vorliegenden Arbeit wurde Ketaminhydrochlorid (10 mg/kg) und Diazepam (0.5 mg/kg) intramuskulär gespritzt, um die Praemedikation bei den Katzen zu schaffen. Zur Fortführung der Anästhesie wurde 3 mg/kg Propofol intravenös verabreicht. Vor- und während der Anästhesie wurde von allen Tieren Blutproben entnommen, um labordiagnostische und biochemische Untersuchungsparameter auszuwerten. Während der Anästhesie zeigten die Atemfrequenz und die Körpertemperatur ein signifikanten Abfall (P<0.01) im Vergleich zum Ausgangswert, der statistisch bedeutend war. Die Werte von Monozyten (P<0.01), Hämatokrit (P<0.05), Kreatinin (P<0.05), Neutrophile (P<0.01), Lymphozyten (P<0.01) und Gesamtprotein (P<0.05) zeigten eine signifikante Veränderungen während der Anästhesie im Vergleich vor der Anästhesie, aber diese Werte liegen im Referenzbereich. Auffälligste Nebenwirkung von Propofolinjektion war eine vorübergehende Apnoe. Diese Kombination scheint als, die für kurz dauernde chirurgische Eingriffe und zur Prämedikation vor der Inhalationsanästhesie geeignet sind

A new vibrational level of the H2+_2^+ molecular ion

A new state of the H$_2^+$ molecular ion with binding energy of 1.09$\times10^{-9}$ a.u. below the first dissociation limit is predicted, using highly accurate numerical nonrelativistic quantum calculations. It is the first L=0 excited state, antisymmetric with respect to the exchange of the two protons. It manifests itself as a huge p-H scattering length of $a=750\pm 5$ Bohr radii.Comment: 6 pages + 3 figure

Investigations on pests, diseases and present early warning system of apple orchards in Isparta, Turkey

As a result of three year surveys performed in the apple orchards in Isparta region, 19 pest species belonging to 4 orders were determined and it was found that the main pest was codling moth. Most of the predators and parasitoids were effective against aphids and they were mostly found in the orchards where selective pesticides were used. Apple scab and powdery mildew were the most common and important diseases. Biology of codling moth and apple scab in the region were investigated. By using the obtained data, proper application times were given and some recommendations regarding integrated pest management program in apple orchards, were summarized

Diagnostic value of combined serum biomarkers for the evaluation of liver fibrosis in chronic hepatitis C infection: A multicenter, noninterventional, observational study

Background/Aims: The hepatitis C virus (HCV) infection is important cause of chronic hepatitis. Liver biopsy is considered the gold standard for assessment of fibrosis but this procedure is an invasive procedure. We aimed to evaluate the diagnostic efficiency of non-invasive serum biomarkers, separately and in combinations, on liver fibrosis in treatment-naive chronic hepatitis C (CHC) patients. Materials and Methods: Two hundred and sixteen treatment-naive CHC patients were enrolled from 32 locations across Turkey in this open-labelled, non-interventional prospective observational study. FibroTest®, aspartate aminotransferase-to-platelet ratio index(APRI), aspartate aminotransferase and alanine aminotransferase ratio (AAR), fibrosis index based on four factors (FIB-4), Age-platelet(AP) index and Forns index were measured and compared with Metavir scores got from liver biopsies. Results: Data from 182 patients with baseline liver biopsy were suitable for analysis. One hundred and twenty patients (65.9%) had F0-F1 fibrosis and 62 patients (34.1%) had F2-F4 fibrosis. APRI 0.732 area under the curve(AUC) indicated advanced fibrosis with 69% sensitivity and 77% specificity. FIB-4 0.732 AUC and FibroTest 0.715 AUC indicated advanced fibrosis with 69% and 78.4% sensitivity, and 75% and 71.4% specificity, respectively. The combined use of tests also led to an increase in AUC and specificity. Combinations of FibroTest with APRI and/or FIB-4, and FIB-4 with APRI were optimal for the evaluation of liver fibrosis. Conclusion: Fibrotest, FIB-4, APRI, AP index and Forns index exhibit good diagnostic performance for determining liver fibrosis in CHC patients, and the use of at least two tests together will increase their diagnostic value still further. © Copyright 2018 by The Turkish Society of Gastroenterology

Paving Luteolin Therapeutic Potentialities and Agro-Food-Pharma Applications: Emphasis on in Vivo Pharmacological Effects and Bioavailability Traits

Luteolin is a naturally occurring secondary metabolite belonging to the class of flavones. As many other natural flavonoids, it is often found in combination with glycosides in many fruits, vegetables, and plants, contributing to their biological and pharmacological value. Many preclinical studies report that luteolin present excellent antioxidant, anticancer, antimicrobial, neuroprotective, cardioprotective, antiviral, and anti-inflammatory effects, and as a consequence, various clinical trials have been designed to investigate the therapeutic potential of luteolin in humans. However, luteolin has a very limited bioavailability, which consequently affects its biological properties and efficacy. Several drug delivery strategies have been developed to raise its bioavailability, with nanoformulations and lipid carriers, such as liposomes, being the most intensively explored. Pharmacological potential of luteolin in various disorders has also been underlined, but to some of them, the exact mechanism is still poorly understood. Given the great potential of this natural antioxidant in health, this review is aimed at providing an extensive overview on the in vivo pharmacological action of luteolin and at stressing the main features related to its bioavailability, absorption, and metabolism, while essential steps determine its absolute health benefits and safety profiles. In addition, despite the scarcity of studies on luteolin bioavailability, the different drug delivery formulations developed to increase its bioavailability are also listed here.This study was partially supported by Çanakkale Onsekiz Mart Üniversitesi (Scientific Research Projects, ID: FYL-2017-1339 and FBA-2017-1268)

Veronica plants-drifting from farm to traditional healing, food application, and phytopharmacology

The Veronica genus, with more than 200 species, belongs to the Plantaginaceae family and is distributed over most of the Northern Hemisphere and in many parts of Southern Hemisphere. These plants are traditionally used in medicine for wound healing, in the treatment of rheumatism, and in different human diseases. This paper reviews the chemical composition of some valuable Veronica species, the possibilities Veronica extracts have in food preservation and as food ingredients, and their functional properties. Veronica species represent a valuable source of biological active secondary metabolites, including iridoid glycosides and phenolic compounds. In particular, due to presence of these phytochemicals, Veronica species exhibit a wide spectrum of biological activities, including antimicrobial and antioxidant. In fact, some studies suggest that some Veronica extracts can inhibit foodborne pathogens, such as Listeria monocytogenes, but only a few of them were performed in food systems. Moreover, anticancer, anti-inflammatory, and other bioactivities were reported in vitro and in vivo. The bioactivity of Veronica plants was demonstrated, but further studies in food systems and in humans are required.M.d.M.C. is grateful for funding from the “Acción 6 del Plan de Apoyo a la Investigación de la Universidad de Jaén, 2017–2019”.

Spliceosome mutations in uveal melanoma

Uveal melanoma (UM) is the most common primary intraocular malignancy of the eye. It has a high metastatic potential and mainly spreads to the liver. Genetics play a vital role in tumor classification and prognostication of UM metastatic disease. One of the driver genes mutated in metastasized UM is subunit 1 of splicing factor 3b (SF3B1), a component of the spliceosome complex. Recurrent mutations in components of the spliceosome complex are observed in UM and other malignancies, suggesting an important role in tumorigenesis. SF3B1 is the most common mutated spliceosome gene and in UM it is associated with late-onset metastasis. This review summarizes the genetic and epigenetic insights of spliceosome mutations in UM. They form a distinct subgroup of UM and have similarities with other spliceosome mutated malignancies
