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, ... -
Alterations in Promoter Methylation Status of Tumor Suppressor HIC1, SFRP2, and DAPK1 Genes in Prostate Carcinomas
Hypermethylated genomic DNA is a common feature in tumoral tissues, although the prevalence of this modification remains poorly understood. We aimed to determine the frequency of five tumor suppressor (TS) genes in prostate ... -
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 ... -
