Plants that lack chlorophyll are rare and typically restricted to holoparasites that obtain their carbon, water and mineral resources from a host plant. Although not parasites in the traditional sense, albino foliage, such as the sprouts that sometimes develop from redwood tree trunks, are comparable in function. They occur sporadically, and can reach the size of shrubs and in rare cases, trees...

Retinal ganglion cell loss was investigated in the retinae of albino quails before and after the development of glaucoma. The isodensity maps of ganglion cells, the total number of ganglion cells, and the histograms of the cell size in the central region of the retina were similar between albino quails without glaucoma and pigmented quails. However, ganglion cells in the intermediate and periph...

To study the effect of CGP 35348 on learning and memory in albino mice following hypoxia ischemia insult, 10 days old albino mice were subjected to right common carotid artery ligation followed by 8% hypoxia for 25 minutes. Following brain damage, mice were fed on normal rodent diet till they were 13 week old. At this time point, mice were divided into two groups. Group 1 received saline and gr...

background: hymenocardia acida is traditionally used in african herbal medicine and has numerous therapeutic benefits. but little is known about its potentially negative effects on pregnant women. objective: the aim of the present study was to evaluate the antifertility effect of aqueous ethanolic extract of hymenocardia acida stem bark in female wistar rats. materials and methods: four groups ...

introduction: heavy ions are nucleus of elements of iron, argon, carbon and neon that all carry positive electrical charges. for these particles to be useful in radiotherapy they need to accelerated to high energy by more than thousand mega volts. also the cosmic environment is considered to be a complicated mixture of highly energetic photons and heavy ions such as iron. therefore, the health ...

The 2,3,7,8-tetrachlorodibenzo-p-dioxin-inducible cytochrome P-450 gene family (P1-450 and P3-450 in the C57BL/6N mouse) has recently been localized to mouse chromosome 9. In the present study, HindIII-digested DNA from Chinese hamster, mouse, and 20 Chinese hamster X mouse somatic cell hybrids and subclones segregating hamster chromosomes was probed with the mouse P1-450 and P3-450 full-length...

Stomatal openings can be stimulated by light through two signalling pathways. The first pathway is blue light specific and involves phototropins, while the second pathway mediates a response to photosynthetically active radiation (PAR). This second pathway was studied with the use of albino Vicia faba plants and variegated leaves of Chlorophytum comosum. Treatment of V. faba with norflurazon (N...

Hamster sarcomas induced by the Gross pseudotype of Moloney sarcoma virus yielded a virus sarcomagenic for hamsters but not mice. This virus was able to produce foci on hamster embryo cells, but not on mouse embryo cells. A hamster-tropic nonfocus-forming helper virus was also found in the viral stocks. These hamster-tropic viruses are not immunologically related to the murine viruses in the or...

The poultry red mite Dermanyssus gallinae, known as the primarily ectoparasite of laying hens and synanthropic birds (e.g. pigeons), can also bite humans, causing Red-Mite Dermatitis (RMD) with untypical symptoms erythematous maculo-papular rash urticaria-like lesions. In this study, we present first case RMD diagnosed in a 12 year old boy, resulting from bites mites derived his pet hamster. re...

PURPOSE To compare emmetropization in albino and pigmented guinea pigs. METHODS Distributions of refractive state were examined in 214 albino and 234 pigmented guinea pigs. Albino (A) and pigmented (P) guinea pigs were divided into two groups, hyperopic (H) and myopic (M). Eye development was separately followed in 10 randomly selected animals from each group (AH, AM, PH, PM) from 2 to 10 wee...
