Neighbouring orogenic gold deposits may be the products of unrelated mineralizing events

Orogenic gold deposits: A proposed classification in the context of their crustal distribution and relationship to other gold deposit types

The so-called ‘mesothermal’ gold deposits are associated with regionally metamorphosed terranes of all ages. Ores were formed during compressional to transpressional deformation processes at convergent plate margins in accretionary and collisional orogens. In both types of orogen, hydrated marine sedimentary and volcanic rocks have been added to continental margins during tens to some 100 milli...

Patent foramen ovale may be causal for the first stroke but unrelated to subsequent ischemic events.

BACKGROUND AND PURPOSE Studies with very long follow-up are scarce in patients with cryptogenic stroke and patent foramen ovale (PFO). Little is known about the etiology of recurrent cerebrovascular events (CVE) in PFO patients. METHODS We collected information on recurrent CVE in 308 patients with cryptogenic stroke and PFO and sought to determine concurrent stroke causes that had emerged or...

The dairy fat paradox: Whole dairy products may be healthier than we thought

Model Which May Be Relevant to the New Lep Events

A multi-Higgs model with an extra neutral gauge boson (Z ′) is introduced. One scalar Higgs boson (H 2) in this model decays dominantly into a photon pair. The Z ′ decay to µ + µ − gets a much larger branching ratio than the Z decay to this channel. The ZZ ′ H 2 vertex provides a final state from Z decay resembling the new l + l − γγ events at the LEP. Other promising phenomenology, such as Z →...

AdipoRon may be benefit for atherosclerosis prevention

Atherosclerosis has serious role in coronary arteries disease,so it is important to establish effective strategies for prevention or even treatment of atherosclerosis. Adiponectin, as one of the most abundant adipokines, has insulin sensitivity, anti-inflammatory and anti-atherogenic properties. Disturbed adiponectin actions through its receptor, (AdipoR1 and AdipoR2) may be involved in atheros...
