background: methionine has been suggested as the firstlimitingamino acid for milk production in ruminants. it is importanthow to increase milk protein yield and milk fat in dairy ruminants.objectives: this study was set to investigate the effect of rumenprotected methionine (rpmet) on milk composition of lactatingcashmere rayeni goats. methods: 40 healthy singletoncashmere rayeni goats about 3 ...

The p53 tumor suppressor is an essential barrier against cancer, which is evidenced by loss of p53 activity in the majority of human cancers and unexceptionally early onset of tumors in p53-knockout mice and human Li-Fraumeni syndrome patients. p53 is a sequence-specific transcription factor that regulates gene expression via binding to the consensus p53-responsive element (p53-RE). p53 acts as...

nloaded ection of circulating tumor cells (CTC) is advancing as an effective predictor of patient outcome and eutic response. Unfortunately, our knowledge of CTC biology remains limited, and the impact of treatments on CTC metastatic potential is currently unclear. Improved CTC imaging in vivo and is of free-floating tumor cells now show that cytoskeletal regulation in CTCs contrasts starkly wi...

This paper presents the MIC∗ algebraic structure modelling an environment where autonomous, interacting and mobile entities evolve.

for vectors x, y ∈ rn, it is said that x is left matrix majorizedby y if for some row stochastic matrix r; x = ry. the relationx ∼` y, is defined as follows: x ∼` y if and only if x is leftmatrix majorized by y and y is left matrix majorized by x. alinear operator t : rp → rn is said to be a linear preserver ofa given relation ≺ if x ≺ y on rp implies that t x ≺ ty onrn. the linear preservers o...

Gram-positive cocci are important causes of both nosocomial and community-acquired infections, and antimicrobial resistance among these pathogens has become an important problem worldwide. Since resistance among these organisms can vary substantially by geographic location, we conducted a multicenter surveillance study with isolates from five Latin American countries (15 medical centers). Quinu...

a method for determination of juglone in leaves and hulls of pterocarya fraxinifolia was developed, based on rp-hplc. this compound was extracted from leaves and hulls by chloroform refluxing about 2 hours. the chloroform was evaporated under low pressure at   50 ºc to produce a dry residue. the remained materials were dissolved in acetonitrile to be used for determination of this compound. app...
