Arterial hypertension is a common condition worldwide and an important risk factor for cardio- cerebrovascular events, renal diseases, as well microvascular eye diseases. Established leads to the chronic vasoconstriction of small arteries decreased lumen diameter thickening arterial media or wall with consequent increased media-to-lumen ratio (MLR) wall-to-lumen (WLR). This process, defined vas...

Abstract Background Ulcerative colitis (UC) is an inflammatory bowel disease that results in inflammation of the colonic mucosa, leading to abdominal pain, rectal bleeding, weight loss, and diarrhea. This chronic a 2.4-fold increased future risk developing colorectal cancer (CRC) UC patients compared general population. Thus, careful dysplasia screening modalities are required prevent progressi...

It is almost fifty years since Mr Bolam was injured when receiving ECT and he unsuccessfully sued the hospital for damages. However, while the world and Medicine have moved on, the principles set out by McNair J in his clear and simple direction to the jury are still in force today (though with a little gloss and froth added by successive judgments). In a nutshell, a doctor is not negligent if ...

The final quarter of the twentieth century has seen the arrival of the claim for educational malpractice, or educational negligence, by students who have failed to learn. Generally speaking, the claim has been that the professional behaviour of teachers, or educational psychologists and/or other providers of educational services has breached the duty of care to educate, with the consequence tha...

We present terminal velocities of M33 B-supergiants, obtained from STIS HST spectra as part of our programme to investigate the Wind Momentum – Luminosity Relationship (WLR) in the Local Group. Terminal velocities are derived from their N V, C IV, and Si IV resonance lines in UV spectra. Comparing with IUE spectra of Galactic B-supergiants we found evidence of low metallicity in three of our ob...

A special class of tunable liquid microlenses is presented here. The microlenses are generated by an electrowetting effect under an electrode-less configuration and they exhibit two different regimes that are named here as separated lens regime (SLR) and wave-like lens regime (WLR). The lens effect is induced by the pyroelectricity of polar dielectric crystals, as was proved in principle in a p...
