In Drosophila, the eye and antenna originate from a single epithelium termed the eye-antennal imaginal disc. Illumination of the mechanisms that subdivide this epithelium into eye and antenna would enhance our understanding of the mechanisms that restrict stem cell fate. We show here that Dip3, a transcription factor required for eye development, alters fate determination when misexpressed in t...
The regulation of corticotropin-releasing factor (CRF) mRNA expression in the rat brain by glucocorticoids and stress was examined by Northern blot analysis and in situ hybridization histochemistry. Rats either were exposed to a single electrical footshock session and killed 2, 4, 12, or 24 hr later (acute stress), or were subjected to the same regimen twice daily for 3 or 7 d and killed on the...
abstract in order to study the effects of irrigation regimes and plant spacing on bulb yield of two onion (allium cepa l.) genotypes, an experiment was conducted at kabootar abad research station of isfahan during two growing seasons (2005 and 2006). the experiment design was split-factorial with a randomized complete block arrangement with four replications. main plots included three irrigatio...
The genus Nagelus (Thorne and Malek, 1968) Siddiqi, 1979 is modified and a new species from Alaska is described. The combination of scanning electron microscopy and light microscopy permits the characterization of Nagelus spp. as having a broadly oval face pattern, no longitudinal striations on the lip region, deirids surrounded by six incisures, and an irregularly tapering tail with a large hy...
All the varieties are not performed equally in all agroclimatic and soil conditions. A field experiment was conducted at Agricultural farm of Lovely Professional University, Punjab to evaluate growth yield performance garlic cultivars alluvial Punjab. T Ten viz., Fewari, G-50, G-323, G-189, G-1, Parvati-2, G-389, G-384, G-282, G-404 were considered as experimental treatments, The arranged a ran...
Agronomic performance of garlic is speculated strongly affected by genotype ´ environment interaction, however, interaction evaluation rarely studied in Indonesia. This research aimed to study the agronomic response four varieties two different locations. The was conducted from April December 2021 using Lumbu Putih, Hijau, Kuning, and Tawangmangu Baru genotypes grown locations, i.e., Lembang (1...
The Gld gene of Drosophila melanogaster is transiently expressed during every stage of development. The temporal pattern of Gld expression is highly correlated with that of ecdysteroids. Exogeneous treatment of third instar larvae with 20-hydroxyecdysone induces the accumulation of Gld mRNA in the hypoderm and anterior spiracular gland cells. During metamorphosis Gld is expressed in a variety o...
BACKGROUND The mammalian hair represents an unparalleled model system to understand both developmental processes and stem cell biology. The hair follicle consists of several concentric epithelial sheaths with the outer root sheath (ORS) forming the outermost layer. Functionally, the ORS has been implicated in the migration of hair stem cells from the stem cell niche toward the hair bulb. Howeve...
abstract background: far lateral discal herniation is an uncommon disorder and is difficult to assess by physical examination alone. this study is designed to define clinical and epidemiological findings and to establish the indications of surgical and medical treatment for flldh. methods: between 2000 and 2005, a total of 2035 patients with lumbar disc herniation underwent surgical discect...
