A comparison of market landings during fish spawning seasons to better understand the effectiveness of the temporal fishery closure in Turkey
(2020)Seasonal fishery closures are an input control measure to reduce fishing pressure on spawning stocks in fisheries management. Despite the huge foregone economic losses from such closures, the efficacy of them has yet ... -
A new approach for estimating stock status from length frequency data
This study presents a new method (LBB) for the analysis of length frequency data from commercial catches. LBB works for species that grow throughout their lives, such as most commercially-important fish and invertebrates, ... -
Anti-invariant and Lagrangian submersions from trans-Sasakian manifolds
(2020)We study anti-invariant and Lagrangian submersions from trans-Sasakian manifolds onto Riemannian manifolds. We prove that the horizontal distributions of such submersions are not integrable and their fibers are not ... -
Apoptotic effects of acacetin in human colon cancer HT‑29 and HCT 116 cells
(2020)Aim: Acacetin is a natural flavone compound, which is found in several plants as Robinia pseudoacacia and is demonstrated to haveanticancerogenic activities in many types of cancer (e.g., human nonsmall cell lung cancer, ... -
Artificial food sweetener aspartame induces stress response in model organism Schizosaccharomyces pombe
Aspartame (APM) is a non-nutritive artificial sweetener that has been widely used in manyproducts since 1981. Molecular studies have found that it alters the expression of tumoursuppressor genes and oncogenes, forms DNA-DNA ... -

EFFECTS OF ALL-TRANS RETINOIC ACID ON REDUCING HYPEROXIA-INDUCED OXIDATIVE STRESS IN MICE BRAIN.
(2013)ABSTRACTObjective: Brain is a very sensitive organ to oxidative stress due to its large amount of polyunsaturated fatty acid content and low antioxidant activity. In this study, effect of exogenous all-trans-retinoic acid ... -
First Large-Scale Eastern Mediterranean and Black Sea Stock Assessment Reveals a Dramatic Decline
The Mediterranean Sea is classified as a “data-poor” region in fisheries due to its low number of assessed stocks given its biodiversity and number of exploited species. In this study, the CMSY method was applied to assess ... -

(2020)A sighting of a group of false killer whale (Pseudorca crassidens) was reported for the first time in the northern Aegean Sea. It was also the first reported sighting in 25 years for the Aegean ... -
Gastrin-releasing peptide induces fibrotic response in MRC5s and proliferation in A549s
Idiopathic pulmonary fibrosis (IPF) is a complex lung disease, whose build-up scar tissue is induced by severalmolecules. Gastrin-releasing peptide (GRP) is released from pulmonary neuroendocrine cells, alveolar macrophages,and ... -
Hemi-Slant Submanifolds of A Locally Conformal Kaehler Manifold
