Article Citation - WoS: 21Citation - Scopus: 22Effects of Spaceflight on Cells of Bone Marrow Origin(Aves, 2013) Özçivici, EnginOnce only a subject for science fiction novels, plans for establishing habitation on space stations, the Moon, and distant planets now appear among the short-term goals of space agencies. This article reviews studies that present biomedical issues that appear to challenge humankind for long-term spaceflights. With particularly focus on cells of bone marrow origin, studies involving changes in bone, immune, and red blood cell populations and their functions due to extended weightlessness were reviewed. Furthermore, effects of mechanical disuse on primitive stem cells that reside in the bone marrow were also included in this review. Novel biomedical solutions using space biotechnology will be required in order to achieve the goal of space exploration without compromising the functions of bone marrow, as spaceflight appears to disrupt homeostasis for all given cell types.Article Citation - Scopus: 2Identification of Potato Y Potyvirus (pvy°) Resistance in Wild and Cultivated Tomatoes(Türkiye Klinikleri Journal of Medical Sciences, 2009) Çelebi Toprak, Fevziye; Barutçu, Eminur; Frary, Anne; Doğanlar, SamiPotato Y potyvirus (PVY) is an important plant pathogen worldwide that infects and causes yield losses in the family Solanaceae including potato (Solarium tuberosum), pepper (Capsicum spp.), tomato (S. lycopersicum), and tobacco (Nicotiana tabacum). In this study, 20 different tomato accessions representing 6 different species were mechanically inoculated with PVY°. The plants were scored visually for symptoms and then tested for presence of the virus 2-4 weeks after inoculation by ELISA. The results were variable. Most wild species of tomato sustained PVY° replication in inoculated leaves. Some of the wild species showed an immune response, while some became systemically infected. Inoculation and analysis of F2 populations suggested that the resistance is controlled by a single recessive gene in different wild species.
