As a liquid-liquid system is far from equilibrium state, the phase thickness is variable when mass transfer process with chemical reaction occurs in interphase zone, and a dispersible transitional layer called the interphase dispersed zone IDZ is formed. The IZD model composed of thermodynamically instable O/W or W/O microemulsion has reasonably explained enormous experimental phenomena in nonl...
The nediodorsal thalamic nucleus (MD) afferents originating in the prefrontal cortex (PFC) were studied in 14 dogs, using the method of retrograde horseradish peroxidase transport. Injections limited to small areas of MD indicated that projection between MD and PFC shows precise topography and reciprocity. However, the distribution of labeled neurons suggests a division of MD into two main segm...
Sulphur status of some soils in Edo Central, Nigeria was evaluated in five different locations; Ekpoma, Irrua, Uromi, Ubiaja and Agbede. The area lies within the derived savanna-forest transitional zone. Surface soil samples (0 – 15 cm) collected from the five localities wasanalyzed for their physico-chemical properties, inorganic, organic and total sulphur contents. Results showed that inorgan...
Both benign prostatic hyperplasia (BPH) and prostate cancer (PCa) are frequent diseases in middle-aged to elderly men worldwide. While both diseases are linked to abnormal growth of the prostate, the epidemiological and pathological features of these two prostate diseases are different. BPH nodules typically arise from the transitional zone, and, in contrast, PCa arises from the peripheral zone...
Wiskott-Aldrich syndrome (WAS) is an X-linked immunodeficiency disorder frequently associated with systemic autoimmunity, including autoantibody-mediated cytopenias. WAS protein (WASp)-deficient B cells have increased B cell receptor (BCR) and Toll-like receptor (TLR) signaling, suggesting that these pathways might impact establishment of the mature, naive BCR repertoire. To directly investigat...
The hyporheic exchange (HE) is defined as the interaction between stream water and groundwater, where the stream water passes back and forth between the active channel and subsurface flow paths (Runkel, 1998). The zone of this exchange is characterized by saturated pore spaces, under sand or gravel stream beds (Hancock, 2002) and near the adjacent banks of the stream (Ryan, 2010), that contain ...
بر اساس پخش و پراکندگی چینه شناسی روزنبران پلانکتونیک شناسایی شده از برش مورد پژوهش 9 بیوزون شناسایی و معرفی شد که منطبق با بایوزون های استاندارد جهانی در قلمرو تتیس بوده و به ترتیب ازپایین به بالا شامل : بیوزون 1)dicarinella concavata interval zone (سانتونین پسین) بیوزون 2) dicarinella asymetrica total range zone ( کامپانین میانی) بیوزون 3) globotruncanita elevata interval zone ( کامپانین پ...
Abstract The ratio of female to male Walleye Sander vitreus across the spatial scale large reservoirs and during nonspawning times receives little attention, even though standardized sampling occurs this time. This study evaluated whether proportion collected from seasonal at different areas within a reservoir fell 0.450–0.550 range, which would closely reflect 1:1 female-to-male sex ratio. We ...
Lithodytes lineatus (Schneider, 1799) is a small, litter-dwelling frog widely distributed in the Amazon Ecoregion and some transitional areas between Cerrado. Here we report seven new records of this species zone Amazon, Chiquitano Dry Forest Cerrado ecoregions state Mato Grosso, Brazil. These are southernmost species, expanding its distribution 320 km from nearest record Bolivia.
