Effect of supplemental potassium (K+) on growth, physiological and biochemical attributes of wheat (Triticum aestivum L.) grown under saline conditions

Date: 14-12-2010 13:23

Present experiment was conducted to assess the ameliorative effects of soil and foliar application of potash fertilizers SOP (Sulphate of potash) & MOP (Muriate of potash) on five wheat cultivars (Sitta, Sehar, Bhakkar 2006, PFAU#VEE, S-24), subjected to salt stress by applying NaCl (10 dSm-1) to the growth medium. Different treatments of potash fertilizers used included: ... read full abstract ››

Expression of chemokines and chemokine receptors in human breast cancer cells under inflammatory stimuli. Implications for cancer metastasis.

Date: 09-12-2010 00:11

Interactions between tumour cells and microenvironments may affect their growth and metastasis formation. Several studies have demonstrated the important role of cellular mediators in the progression of breast cancer cells. The effect of pro-inflammatory cytokines, such as IL-1, IL-6, TNF-α and IFN-g on the regulation of expression of chemokine receptors and autocrine-pa ... read full abstract ››

Chemical and Microbiological study in the hyper-arid environment from Pampas de La Joya, Atacama Desert southern Peru, as a new analogue to Mars

Date: 08-12-2010 23:42

The distribution of living organisms, organic matter, and chemical properties in Mars-like environments on Earth can be used as a model to guide the investigation of possible habitable environments on Mars.

This dissertation aims to demonstrate that Pampas de la Joya Desert, located along the Pacific coast of southern Peru between 15 and 17° S, is a possible analog ... read full abstract ››

An Architecture for an Ur-Universe: Sequential Universal Events

Date: 18-11-2010 19:30

The dissertation will address the concept of a pre-Big Bang universe that is older than the traditional 13.7 billion years given the current Big Bang model of nucleogenesis. Many large scale structures of the universe, planets and galaxy\'s, are much older than the 13.7 billion years given for the current timeline of a singular Big Bang theory of universe creation. The monogra ... read full abstract ››

Analysis of the Arabidopsis Mitogen-Activated Protein Kinase families: organ specificity and transcriptional regulation upon water stresses

Date: 10-11-2010 04:20

The Arabidopsis genome encodes for 20 MPKs, 10 MKKs, 60 MAP3Ks, and 10 MAP4K genes. The functions of corresponding proteins are still poorly characterized. To research possible functional MAP kinase modules involved in water stress signaling, original macroarrays were developed for their sensitivity and specificity. The expression patterns of MPKs and MKKs gene families, as we ... read full abstract ››

Analysis of left ventricular myocardial regional and global contractility using speckle tracking post aortic valve replacement for aortic stenosis.

Date: 24-08-2010 19:47

Abnormalities in regional left ventricular (LV) function in severe aortic stenosis (AS) have yet to be appropriately characterized. Often patients with severe aortic stenosis have subclinical left ventricular systolic dysfunction despite having preserved ejection fraction and fractional shortening on conventional echocardiography. In these patients, the occult, systolic abnorm ... read full abstract ››

Autonomic dysfunction and phase 2 ventricular fibrillation post myocardial infarction

Date: 24-08-2010 19:23

Sudden cardiac death (SCD) claims 100,000 lives in the UK and over 400,000 in the USA. In humans the spatial and temporal patterns of ventricular fibrillation (VF) are poorly characterised .However, if VF is phase dependant like it is in animal models, then phase 2 VF would account for 87 % of VF related sudden cardiac deaths in humans. This would explain why most deaths (50-8 ... read full abstract ››

The influence of Prostaglandin E2 on bradykinin induced depolarization, generation and conduction of action potentials in the isolated vagus nerve

Date: 24-08-2010 19:18

In this study we have investigated the sensitising effect that PGE2 has on the action of bradykinin (BK) in both depolarising the resting membrane potential and in action potential generation and propagation in the isolated, desheathed vagus nerve of the rat using an extra cellular grease gap recording technique. Treatment with proinflammatory PGE2 (1µM) produced a signi ... read full abstract ››

Exact Sequence Computing with DNA Sequences

Date: 13-08-2010 04:17

This work enlightens the present and future research aspects of Exact Sequence Computing with DNA Sequences. DNA computing is a form of computing which is a fast developing research area. In this research work, the first process is to take the different samples of DNA for comparison and computing has been done systematically. After analyzing with various algorithms the newly f ... read full abstract ››

Elevation change detection in the Firiza area using GIS techniques

Date: 17-07-2010 13:23

Nowadays, any geographical study has its applicability in G.I.S. Between the large number of applications available in G.I.S. software we can find many that deal with elevation changes. Our study takes advantage of such a tool, “Minus tool”, integrated in the ArcMap 9.3© software, to present the elevation changes that occurred in the Firiza zone (near Baia Mar ... read full abstract ››
