background:non-melanoma skin cancer (nmsc), the most prevalent types being squamous cell carcinoma (scc) and basal cell carcinoma (bcc), is the most common type of malignancy in human beings. these neoplasms are more frequent in the elderly and fair skinned people and mainly occur on sun-exposed sites of the body. ultraviolet b (uvb) has a well-known effect in induction and promotion of growth ...

OBJECTIVES Hyperthermia is one of the most common environmental stressors that affect multi-biological systems in the body including the central nervous system as well as the hematopoietic organs. The objective of the present study was to investigate the protective role of ethanolic extract of propolis (EEP) on some selective stress markers, hematological, biochemical, and histopathological cha...

Acetylcholine (ACh) plays a permissive role in developmental plasticity of fibers from the lateral geniculate nucleus (LGN) to the primary visual cortex (V1). These fibers remain plastic and express long-term potentiation (LTP) in adult rodents, but it is not known if ACh modulates this form of plasticity in the mature V1. We show that, in anesthetized rats, theta burst stimulation (TBS) of the...

A preliminary analysis of the timing landscape anthropization in southern-central Pyrenees shows occurrence an elevational gradient from Bronze Age (basal belts) to Middle Ages (alpine belts). This relationship is statistically significant and suggests average rate 40 m elevation per century. The most clear between Roman occupation, suggesting a progressive upward trend south with likely involv...

Tumor subclasses with clinical implications are identified by breast cancer gene expression patterns. In this study, ROBERT TIBSHIRANI et al. make a suggestion. Based on changes in expression, the tumours were divided into three groups: basal epithelial-like, ERBB2-overexpressing, and normal breast-like. Two separate sets, one representing collection of 456 cDNA clones originally chosen to refl...

BACKGROUND Bone density at the interradicular area plays an important role during orthodontic treatment. In view of this fact, the study was designed to quantitatively evaluate the bone density at the interradicular areas of the alveolar and basal bones of maxilla and mandible by computed tomography. METHODS One hundred and nine computed tomographic images were randomly selected, and bone den...

this experiment was conducted to determine the ame, amen, tme and tmen of beet pulp fed to male ostriches at  their 90 d of age. different levels of beet pulp (0, 15, 30 and 40%) were fed through replacements in the basal diet. for a determination of ame and amen using marker method, beet pulp was replaced in the basal diet at 40%. a number of 16 vs. 8 ostrich chicks were employed in each of th...

The title compound, C(51)H(78)INO(12), contains a 29-membered ring incorporating amide, lactone and ester groups. It contains a total of 15 stereogenic centres. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, forming C(8) chains propagating in [100]. A weak intra-molecular O-H⋯O inter-action also occurs.

PURPOSE Choroidal vessels compensate for changes in systemic blood pressure (BP) so that choroidal blood flow (ChBF) remains stable over a BP range of approximately 40 mm Hg above and below basal. Because of the presumed importance of ChBF regulation for maintenance of retinal health, we investigated if ChBF compensation for BP fluctuation in pigeons fails with age. METHODS Transcleral laser ...

This research aimed to compare the effects of pigments extracted from dried petal meal of marigold flower and synthetic pigments on productive performance of laying hens, egg quality and antioxidant properties of the egg. A total of 64 laying hens, aged 75 weeks, were distributed in a completely randomized design in 4 treatments and 4 replications containing 4 hens per cages. Experimental group...
