1. Mineral inclusions in diamonds from Chapada Diamantina, Bahia, Brazil: a Raman spectroscopic characterization
Abstract The Chapada Diamantina, located in the central region of the State of Bahia, is of important historical significance due to its diamond occurrences. Discovered in the nineteenth century, comprehensive research about the regional diamonds and their origins are still limited, demanding more investigation in the matter. Looking for insights about their

2. Longevidade foliar, compostos fenolicos e nitrogenados em arvores e lianas de um fragmento de Cerrado na Estação Experimental de Itirapína, São Paulo / Leaf life span, nitrogenous and phenolic compunds in trees and lianas from a Cerrado fragment in the Itirapina experimental station in São Paulo
Trees and lianas present different strategies for allocating resources during the phonological cycle. Whereas Lianas are important floristic components and account for a significant number of rainforest species, few studies have been conducted in the Cerrado (a savanna like vegetation) biome. The duration of the leaf life span in different species reflects b

3. Relação entre longevidade foliar, nitrogenio e compostos secundarios em folhas de leguminosas arboreas
A duração do ciclo de vida foliar determina características distintas nas folhas, que são relevantes para a sobrevivência da planta em diferentes habitats. Tem sido verificado que as espécies perenifólias apresentam mecanismos mais eficientes de conservação de nitrogênio (N) em relação às espécies decíduas. Esses mecanismos são: eficiência d

4. Resorption Protection. Anthocyanins Facilitate Nutrient Recovery in Autumn by Shielding Leaves from Potentially Damaging Light Levels
The resorption protection hypothesis, which states that anthocyanins protect foliar nutrient resorption during senescence by shielding photosynthetic tissues from excess light, was tested using wild-type (WT) and anthocyanin-deficient mutants of three deciduous woody species, Cornus sericea, Vaccinium elliottii (Chapmn.), and Viburnum sargentii (Koehne).

5. Bisphosphonates inhibit the adhesion of breast cancer cells to bone matrices in vitro.
Bisphosphonates are used with increasing frequency in the management of skeletal complications in patients with breast cancer. In this paper, we have investigated whether bisphosphonates, besides their known beneficial effects on tumor-associated osteoclastic resorption, are capable of inhibiting breast cancer cell adhesion to bone matrix. For that we used t

6. The role of bisphosphonates in breast cancer: Development of bisphosphonates
Bisphosphonates are synthetic compounds characterized by a P–C–P group, and are thus analogs of inorganic pyrophosphate. They are used in medicine mainly to inhibit bone resorption in diseases like osteoporosis, Paget's disease and tumor bone disease. They have been used for over a century in industry, and only in 1968 was it shown that bisphosphonates h

7. Alendronate mechanism of action: geranylgeraniol, an intermediate in the mevalonate pathway, prevents inhibition of osteoclast formation, bone resorption, and kinase activation in vitro
Nitrogen-containing bisphosphonates were shown to cause macrophage apoptosis by inhibiting enzymes in the biosynthetic pathway leading from mevalonate to cholesterol. This study suggests that, in osteoclasts, geranylgeranyl diphosphate, the substrate for prenylation of most GTP binding proteins, is likely to be the crucial intermediate affected by these bisp

8. Null Mutation of PCLN-1/Claudin-16 Results in Bovine Chronic Interstitial Nephritis
Inherited chronic renal diseases are associated with failures in glomerular filtration and tubular resorption. Such failures invariably result from defects in selective filtration and absorption in surface renal epithelium. Recently, we described an autosomal recessive chronic interstitial nephritis with diffuse zonal fibrosis (CINF) in cattle. Bovine CINF,
