Best’s disease also termed as vitelliform macular dystrophy is an autosomal dominant sorder which classically presents in childhood with the striking appearance of a yellow or orange yolk like lesion in the macula. Dr Franz Best, a German ophthalmologist, described the first pedigree in 1905. A 23year old male with complain of gradual reduction of vision distortion of images and presence of bli...

Plant extracts of Cissus hastata, indigenously known as Semperai, have been used an effective traditional remedy against coughs. Recently, the leaf extract was potentially shown to anti-hemorrhoid activity, although there is a lack scientific data due its folklore usage. Hence, therapeutic properties phytochemicals and metabolites Semperai remain elusive. Therefore, this study aims determine to...

Carotenoids are secondary metabolites synthesized in plastids that function photosynthesis, photoprotection, growth and development of plants. contribute to the yellowish, orange pinkish-red hues leaves, flowers fruits, as well various aromas. They provide substrates for biosynthesis phytohormones cleavable into smaller apocarotenoids retrograde signals and/or mediate intracellular communicatio...

The colour of a lesion is due to its nature and to its histological substratum. In order to ease diagnosis, oral cavity lesions have been classified according to their colour in: white, red, white and red, bluish and/or purple, brown, grey and/or black lesions. To the best of our knowledge, there is no such a classification for yellow lesions. So, a suggestion for a classification of yellowish ...

The platinum(ii) half-lantern dinuclear complexes [{Pt(bzq)(μ-C7H4NS2-κN,S)}2] () and [{Pt(bzq)(μ-C7H4NOS-κN,S)}2] () [bzq = benzo[h]quinolinate, C7H4NS2 = 2-mercaptobenzothiazolate, C7H4NOS = 2-mercaptobenzoxazolate] in solution of DMSO-H2O undergo a dramatic color change from yellowish-orange to purple and turn-off phosphorescence in the presence of a small amount of Hg(2+), being discernible...

Light therapy, also called phototherapy, exposes infants with jaundice [5], a yellowing of the skin and eyes, to artificial or natural light to break down the buildup of bilirubin pigment in the blood. Bilirubin is an orange to red pigment produced when red blood cells break down, which causes infants to turn into a yellowish color. Small amounts of bilirubin in the blood are normal, but when t...

Fusion power offers the prospect of an almost inexhaustible source of energy for future generations. It was reported that fusion fuel gains exceeding unity on the National Ignition Facility (NIF) were achieved, but so far great deal of scientific and engineering challenges have to be overcome for realizing fusion power generation. There is a bottleneck for color-separation gratings in NIF and o...

A 49-year-old Caucasian man was referred to our Unit for the recent occurrence of a nodular lesion on a long-standing nevus. A smooth, dome-shaped, reddish lesion, 1 cm in diameter, on a flesh-colored plaque with a velvety and verrucous surface was observed (Figure 1). Dermoscopy of the nodule showed yellow to pink-colored lobules of different sizes, interposed by whitish pale septae. Glomerula...

The present study was aimed to develop the high performance thin layer chromatography (HPTLC) finger print profile of methanol and ethyl acetate extracts of leaves of Cassia fistula. Chromatographic technique was used for separation of components from different extracts of leaves. This study was planned to develop a HPTLC fingerprint profile of extracts in different solvents such as petroleum e...

New synthesized reagent 2,6-Diacetylpyridine bis-4-phenyl-3-thiosemicarbazone (2,6-DAPBPTSC) is proposed as a sensitive and selective analytical reagent for the separation and extractive spectrophotometric determination of palladium(II) at pH: 4.0 to form a yellowish orange colored 1:1 chelate complex, which is very well extracted in to isoamyl alcohol. The maximum absorbance was measured at 41...
