Isobutyrate-1-(14)C and l-isoleucine-U-(14)C fed through the petiole labeled the surface lipids of broccoli leaves, but the incorporation was much less than from straight chain precursors. Not more than one-third of the (14)C incorporated into the surface lipids was found in the C(29) paraffin and derivatives, whereas more than two-thirds of the (14)C from straight chain precursors are usually ...

This paper presents a new yet simple family of microactuators that provide both large displacements ( m) and high forces ( N) hence suitable for microvalves. The actuators use the high volumetric expansion of a sealed, surface micromachined patch of paraffin heated near its melting point to deform a sealing diaphragm. Two types of actuators were fabricated using a simple 2-mask process. The fir...

background and objective: formalin-fixed paraffin-embedded tissues are a valuable source of dna for molecular studies. we designed and optimized an efficient procedure for dna extraction from formalin-fixed paraffin embedded tissues. materials and methods: seventy three blocks of cervical paraffin-embedded tissues were investigated. dna was extracted using 45 minutes boiling in alkaline solutio...

introduction: nocardia is saprophytic soil bacterium of the actinomycetes families. nocardia has high diversity of species and due to species diversity of nocardia, phenotypic tests are essential for early identification of nocardia species. methods: 155 soil samples from different regions of north khorasan province in iran were collected, including: urban and rural areas. isolation of nocardia...

The induction of paraffin oxidation in intact cells of Pseudomonas aeruginosa was investigated. Oxidation of (14)C-heptane by cell-free extracts of adapted cells showed that the activity of whole cells is a reliable reflection of the synthesis of the first enzyme in the degradation of n-alkanes. Induction was significantly affected by glucose and could be completely repressed by malate. The ami...

background &objective: breast cancer is the most common female malignancy. detection of dna of human papillomaviruses (hpvs) in breast carcinomas suggests that the virus may play a role in the pathogenesis of this disease. the aim of this study was to evaluate the frequency of hpvs genotypes 6, 11, 16, 18 and 31 in paraffin-embedded tissue samples of invasive breast carcinomas. methods: thr...

The influence of heat transfer characteristics fluids filled with paraffin core-metallic shell nanoencapsulated phase change material (PCM) on photothermal conversion and storage in a volumetrically heated solar system is numerically analysed. results show that paraffin/Al, paraffin/Au, paraffin/Ag, paraffin/Cu enhance the energy by 68, 73, 92 86 %, respectively as compared water-based Al, Au, ...

Vesicular monoamine transporters (VMATs) are a prerequisite for the uptake of biogenic amines into intracellular storage organelles, whereas soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs; such as SNAP-25 and syntaxin1) are essential for exocytosis of biogenic amines by neurons and endocrine cells. In this study, we examined whether these proteins exist in high-g...
