SPECIFICATION AND SPATIAL ARRANGEMENT OF CELLS IN THE GERMLINE STEM CELL NICHE OF THE DROSOPHILA OVARY DEPEND ON THE MAF TRANSCRIPTION FACTOR TRAFFIC JAM.

Germline stem cells in the Drosophila ovary are maintained by a somatic niche.The niche is structurally and functionally complex and contains four cell types, the escort, cap, and terminal filament cells and the newly identified transition cell.We find that the large Maf transcription factor Traffic jam (Tj) is essential for determining niche cell

BACKGROUND:Foot and ankle joint disorders are serious issues for patients with rheumatoid arthritis (RA).We compared the differences between patients with RA whose first symptom involved a foot or ankle joint (FOOT group) versus other joints (non-FOOT group) within the Institute of Rheumatology, Rheumatoid Arthritis (IORRA) cohort in our institute.

An increase in aircraft availability and readiness is one of the most desired characteristics of aircraft fleets.Unforeseen failures cause additional expenses and are particularly critical when thinking about combat jets and Unmanned Aerial Vehicles (UAVs).For instance, these systems are used under extreme conditions, and there can be situations wh
