This study was aimed to determine the effect of a freezing extender developed for Mesopotamian spiny eel (Mastacembelus mastacembelus Banks & Solander, 1794). Mesopotamian spiny eel was caught from May to July 2017 in the Atatürk Dam Lake and Euphrates Basin (meridians) in Şanliurfa, Turkey. During the study, the animals (n=10; 8 males, 2 females) were caught with gill nets (22 mm×22 mm, mesh s...

OBJECTIVE Artificial oocyte activation (AOA) is an effective method to avoid total fertilization failure in human in vitro fertilization-embryo transfer (IVF-ET) cycles. AOA performed using a calcium ionophore can induce calcium oscillation in oocytes and initiate the fertilization process. We evaluated the usefulness of AOA with a calcium ionophore in cases of total fertilization failure in pr...

BACKGROUND Information about gastro-oesophageal reflux disease (GERD) in patients with Diabetes mellitus type 2 (T2D) is scarce, although the incidence of both disorders is increasing. METHODS This "retro-pro" study compared 65 T2D patients to a control group of 130 age- and sex-matched non-diabetics. GERD was confirmed by gastroscopy, manometry, pH-metry and barium swallow. RESULTS In pati...

We study competition between two multi-product firms with distinct production technologies in a market where customers have heterogeneous preferences on a single taste attribute. The mass customizer (MC) has a perfectly flexible production technology, thus can offer any variety within a product space, represented by Hotelling’s (1929) linear city. The mass producer (MP) has a more focused produ...

Haisch and Rueda have recently proposed a model in which the inertia of charged particles is a consequence of their interaction with the electromagnetic zero-point field. This model is based on the observation that in an accelerated frame the momentum distribution of vacuum fluctuations is not isotropic. We analyze this issue through standard techniques of relativistic field theory, first by re...

BACKGROUND Patients with celiac disease who present with symptoms of gastrointestinal hypomotility have abnormal antroduodenal manometry. There are no data on antroduodenal manometry in malabsorption syndrome (MAS) due to causes other than celiac disease. METHODS Fasting, post-prandial and post-octreotide antroduodenal motility parameters were compared in 18 untreated patients with MAS presen...

While the past decade of transitions scholarship has increasingly acknowledged centrality politics, key questions on transition politics deserve further research. Here, we develop a heuristic framework from discipline political science that separates into classic categories interests, ideas, institutions, as well elite and mass politics. Based this framework, conduct review existing literature ...

PURPOSE To compare sperm parameters and intracytoplasmic sperm injection (ICSI) outcomes for testicular spermatozoa frozen on the day of the biopsy (DO) with those frozen after 24 h of in vitro culture (D1). METHODS In this retrospective study, from 1999 to 2012, forty-nine azoospermic patients were included to compare sperm (motility and viability) and outcomes (fertilization (FR), implantat...
