The recognition of basophilic stippling in erythrocytes depends largely on subjective factors such as visual acuity and experience. An expert may observe stippling in the ordinary blood film stained with B.D.H. Leishman stain diluted with water at pH 6.8 to 7.0 when less expert observers may see nothing. If one could increase contrast between the stippling and its background it would become eas...

Thresholds for detecting changes in color are raised following viewing a field sinusoidally modulated in color over time. This effect is highly selective. For example, thresholds for detecting reddish and greenish changes from white are raised following viewing a field varying in a reddish-greenish direction, but not after viewing one varying in a yellowish-bluish direction. Similarly threshold...

Abstract The phenol red is commonly used in cell culture medium as visual pH indicator by changing its color from darker to the orange-yellowish neutral acidic level. change of hardly be determined using naked eyes that will interpreted differently different person. Thus, this study executed develop a specialized colorimeter for measurement Raspberry Pi microcontroller unit, green LED light sou...

Some light green grossular garnets exhibit orange-red luminescence under long-wave and short-wave ultraviolet light. To characterize their behavior, we studied seven with typical colors ranging from yellowish-green to intense by using photoluminescence (PL), ultraviolet–visible (UV–Vis) spectroscopy, electron paramagnetic resonance (EPR), Electron Probe Microanalysis (EPMA) laser ablation induc...

The unique hues--blue, green, yellow, red--form the fundamental dimensions of opponent-color theories, are considered universal across languages, and provide useful mental representations for structuring color percepts. However, there is no neural evidence for them from neurophysiology or low-level psychophysics. Tapping a higher prelinguistic perceptual level, we tested whether unique hues are...

AIM To characterise the role of substitutes for receptor-activator nuclear factor kappa-B ligand (RANKL) in rheumatoid arthritis (RA) joint destruction. METHODS Synovial fluid (SF) macrophages isolated from the knee joint of RA patients were incubated with 25 ng/mL macrophage-colony stimulating factor (M-CSF) and 50 ng/mL LIGHT (lymphotoxin-like, exhibits inducible expression and competes wit...

Multiple necrotic hepatitis lesions of 5 newly hatched broiler chicks in three flocks derived from two hatcheries were examined pathologically. The livers were brittle, and multiple yellowish or green foci were scattered on the surface and cut surface. The main histological finding was well demarcated multi-focal necrosis in the liver. Many Gram-positive large bacilli that reacted positively wi...

Chromatic Adaptation is the ability of the human visual system to approximately preserve the appearance of an object color, no matter which light “color” illuminates a particular scene. We perceive a white piece of paper as white, regardless whether viewed under a bluish daylight or yellowish tungsten light source. Similar effects can be observed with other color hues. Figure 1 illustrates this...
