Drug Improves Kidney Function In Diabetics Pentoxifylline Prevents Protein Leakage Into Urine

�Pentoxifylline, a drug victimized to
handle patients with circulation problems, may as well benefit those with
kidney disease caused by diabetes and other conditions. Specifically,
pentoxifylline decreases proteinuria, the abnormal outflow of protein
into the urine, according to 2 articles in the September issue of the
American Journal of Kidney Diseases, the official journal of the
National Kidney Foundation.



"When kidneys are healthy, very slight or no protein appears in the
urine," says Dr. Kerry Willis, Senior Vice President for Scientific
Activities at the National Kidney Foundation. "Protein in the weewee
is an early sign that the kidney's filters have been damaged by
disease, allowing protein to leak into the pee."



Pentoxifylline makes red blood cells more than flexible to improve
circulation in the smallest blood vessels of the body. It besides has
anti-inflammatory drug properties. Several small clinical trials make
suggested that the drug decreases proteinuria caused by diabetes.



A research team at the Kidney Research Centre and the Ottawa Health
Research Institute in Ontario, Canada, combined information from 10 of these
studies to get a better estimation of scarce how effective pentoxifylline is in
diabetic patients.



A total of 476 patients were treated for close to 6 months.
Pentoxifylline substantially reduced proteinuria, particularly in
patients with the highest levels of urine protein.



According to lead author Dr. Brendan B. McCormick, "Proteinuria is a
substantial risk agent for kidney failure, and by decreasing proteinuria,
pentoxifylline may help in reducing the likeliness that a diabetic
patient will terminal up needing dialysis."



In two of the trials, pentoxifylline was as effective as capoten, a
type of dose called an ACE inhibitor used to treat high blood atmospheric pressure
and to protect kidneys in diabetic patients. This property whitethorn be
especially beneficial in patients wHO cannot acquire ACE inhibitors
because of their side effects.



In the second paper, Dr. Tun-Jun Tsai and colleagues at National Taiwan
University Hospital in Taipei took this construct even further, looking at
how well pentoxifylline worked in concert with losartan, another ACE
inhibitor. The 85 patients had advanced kidney disease due to diabetes
and to glomerulonephritis, a group of diseases that crusade inflammation
and damage to the kidney's filtering units.



After one year, proteinuria was reduced by an additional 40%.



An additive effect 'tween pentoxifylline and ACE inhibitors is
important, Dr. Tsai's group points out, because ACE inhibitors and
drugs like them often lose their effects over time, and pentoxifylline
represents a nontoxic choice for boosting their effectiveness.



Authors of both reports call for larger trials to confirm their
findings, and to see if pentoxifylline actually stops kidney disease
progress.



"A positive finding in this setting would be of profound significance
because it would provide a novel and inexpensive therapy for the growing
orbicular epidemic of diabetic nephropathy," Dr. McCormick's team
concludes.

The National Kidney Foundation is dedicated to preventing and treating
kidney and urinary parcel diseases, improving the health and well being
of individuals and families affected by these diseases and increasing
accessibility of all organs for transplantation.

Psychedelic Horseshit, New Wave Hippies Single Review

Single Review of 'New Wave Hippies' by Psychedelic Horseshit.

Matt (Sing,guitars) and Rich (Drums,shoes) from Columbus, Ohio are "The Shit", a duo world Health Organization have spent much of their formative years patently listening to the art rock of early Sonic Youth and coveting the dishevellment of Beck.

It would be easy to dismiss New Wave Hippies as a joke - it opens with a mercifully brief cod-reggae jam (Dub Gaze) and closes with a demo quality krautrock collage (Magick Defends Itself Pt. 3) - whilst in between on that point are squalls of misdirected feedback and song writing so brittle a dozen year old wouldn't devastate it on their MySpace. Of sole interest is the claim track, which sounds vaguely like a roughed up Suicide and contains the magic

Cinema Expo closes on upswing

Organizers tout upturns in attendance

AMSTERDAM -- After four days of high-profile screenings, receptions themed to promote studio slates and seminars devoted to all things digital, Cinema Expo 2008 wound to a close Thursday with organizers touting upturns in attendance and trade show participation.


Attendance rose more than 6% this year to 1,150 paid registrations.


"We're thrilled with the attendance, and the reason people come here is to check out what's going on in the industry," confab co-managing director Robert Sunshine said. "The industry is changing right now, and that change is digital cinema."


D-cinema also figured big on the confab's large trade show floor, which boasted 210 booths this year, seven more than a year ago.


A strong euro made this year's show particularly affordable, though currency rates also meant that Cinema Expo's U.S. organizers absorbed higher costs in paying for local goods and services with weak American dollars.


Cinema Expo -- owned and operated by a unit of the Nielsen Co., parent of The Hollywood Reporter -- is set to return to its longtime home at the RAI convention center on June 22-25, 2009. Organizers said they didn't expect much impact from a new summer trade show planned for Brussels next year by the International Union of Cinemas, and Hollywood studios have indicated continued support for Cinema Expo.


Cinema Expo's film screenings this year included Warner Bros.' summer tentpole "The Dark Knight," set for a day-and-date bow in most global territories July 18. And the most elaborate dinner event of the week was a reception that Paramount tied to a screening of its August combat comedy "Tropic Thunder," turning a banquet hall into a mist-filled jungle featuring a helicopter, jeeps and hostesses clad in fatigues.


Discussions about d-cinema figured prominently. In Europe, even such core issues as funding and operation remain to be sorted out.


Studios finally have locked down European virtual print fee agreements -- basically arrangements for the majors to help defray much of the $100,000 or so in d-cinema installation costs. It's believed that the closely guarded terms of the regional VPFs are about one-third less generous than what was on offer in the first such deal in the U.S., though scuttlebutt suggests a similar retrenchment in studio largesse there for those arriving late to the VPF party.
