BACKGROUND Intact foveal bulge has been associated with good visual outcome in retinal diseases. The aim of this study was to study the variation in foveal bulge with age. METHODS It was an observational cross-sectional study conducted between October 2014 and December 2015. Totally, 101 eyes of 101 healthy volunteers were studied in a tertiary care center. All individuals had best corrected ...

Recent work has produced a wealth of data concerning the chemical evolution of the galactic bulge, both for stars and nebulae. Present theoretical models generally adopt a limited range of such constraints, frequently using a single chemical element (usually iron), which is not enough to describe it unambiguously. In this work, we take into account constraints involving as many chemical element...

We have identified five new R Coronae Borealis (RCB) stars in the Galactic bulge using the MACHO Project photometry database, raising the total number of known Galactic RCB stars to about 40. We have obtained spectra to confirm the identifications. The fact that four out of the five newly identified RCB stars are “cool” (Teff < 6000 K) rather than “warm” (Teff > 6000 K) suggests that the prepon...

In the retina of teleost fish, continuous neuronal development occurs at the margin, in the peripheral growth zone (PGZ). We prepared tissue slices from the retina of rainbow trout that include the PGZ and that comprise a time line of retinal development, in which cells at progressive stages of differentiation are present side by side. We studied the changes in dendritic structure and voltage-d...

The Arabidopsis thaliana (hereafter Arabidopsis) root has become a useful model for studying how organ morphogenesis emerge from the coordination and balance of cell proliferation and differentiation, as both processes may be observed and quantified in the root at different stages of development. Hence, being able to objectively identify and delimit the different stages of root development has ...

background: transplants of multipotent stem cells have been shown to have a neuroprotective effect after central nervous system injury. the bulge region of the hair follicle has been reported as a putative source of hair follicle stem cells (hfsc) for many years; however, few studies have documented the properties of bulge derived cells in vitro until now. this study was conducted to isolate an...

Our knowledge about the photometric properties of bulges in late-type galaxies (LTGs) is founded upon image decomposition into a S\'ersic model for central luminosity excess bulge and an exponential underlying disk. We argue that standard practice adopting disk all way to its center inadequate because it implicitly neglects fact star formation (SF) quenching (SFQ) centers LTGs. Extrapolating fi...
