Study: Repeated Chest & Cardiac CTs May Increase Breast Cancer ...

A new study presented on Tuesday at the 2012 Radiological Society of North America (RSNA) annual meeting analyzed the records of approximately 250,000 women and found that increased CT utilization over a ten year period could result in an increase in breast cancer risk for certain women. According to study results, nuclear medicine exams may also contribute to increased breast cancer risk.

As a senior author on the study, led by former UCSF resident Ginger Merry, M.D., M.P.H., at Prentice Women?s Hospital- Northwestern Memorial Hospital in Chicago, we found that among the women enrolled in the integrated healthcare delivery system, CT utilization increased from 99.8 CT scans per 1,000 women in 2000 to 192.4 CT scans per 1,000 women in 2010?an annual increase of 6.8 percent.

When a woman undergoes CT or nuclear medicine imaging of her chest, abdomen or spine, her breast tissue will absorb some radiation. Breast tissue is one of the tissues in the body known to be sensitive to developing cancer as a result of radiation exposure. Until now, the impact of this increased use of imaging on radiation exposure to breast tissue and the subsequent risk of breast cancer has not been known. Our goal was to quantify imaging utilization and radiation exposure to the breast among women enrolled in an integrated healthcare delivery system and to use these data to determine the imaging-related risk of breast cancer from those studies.

We found that the estimated breast radiation doses from CT were highly variable across patients, with the highest doses coming from multiple-phase cardiac and chest CT examinations, where successive images of the organ are captured. By estimating each woman?s 10-year imaging-related risk and underlying risk of breast cancer, we found that young women receiving several chest or cardiac CTs had the greatest increased risk of developing breast cancer at approximately 20 percent.

In order to lower imaging-related risk of breast cancer, radiologists must analyze the radiation doses associated with each exam, reduce the use of multi-phase protocols and employ dose-reduction software where possible to minimize exposure. Women should understand that there is a small but real potential risk of breast cancer associated with cardiac and chest CT, but if imaging is truly indicated, the small risk should not dissuade women from getting the test they need.

SAP co-founder sells shares worth more than $155 million

FRANKFURT (Reuters) - SAP's co-founder Hasso Plattner sold shares in the German business software maker worth 120 million euros ($155.74 million), divesting a portion of his overall stake, the company said on Friday.

To protect the stock price, a bank will place 10 million euros worth of the shares every month until no more are left.

"The sale will be carried out at the bank's own discretion in the stock market or over the counter, for the first time in November 2012 and then again in the months January through November 2013," SAP said in a regulatory statement.

SAP shares reversed their gains, trading down 0.5 percent at 59.91 euros by 10:54 a.m. EDT.

Plattner is SAP's largest shareholder with 121.49 million shares, representing a 9.89 percent stake, according to Thomson Reuters data from the end of September. Based on the current share price the stake is worth a little over 7 billion euros.

With a 73 billion euro market capitalization, SAP is the most valuable company in the German blue chip index, followed by Siemens, worth a little under 70 billion.

Western Digital My Book (4TB)


The Western Digital My Book (4TB) ($209.99 list) desktop-class external hard drive gives the photo, music, or video collector a place to keep a whole lot of files. It's basic, utilitarian storage that will get the job done, and sometimes that's all you need. It won't wow you with esoteric connectors, data redundancy, or blazing throughput rates, but it's a good choice if you want to hold a million songs or photos in one place. It's worth picking up for that reason alone.

Design and Features
The My Book looks like a standard black plastic-clad desktop hard drive, with 6.5 by 2 by 5.5 inch (HWD) measurements. It will sit next to your desktop PC or on your desk, waiting to connect to your laptop. Vents on three of the drive chassis' surface mean that the hard drive doesn't require active fan cooling. The drive mechanism is mounted so it "floats" inside, surrounded by cooling air. This means that the drive is more suited to causal use than hardcore file transfers or as a scratch disk for graphics tasks. The benefit of the design is that the drive itself is quiet: without cooling fans, you'll barely be able to hear the drive unless you hold your ear close to the chassis while the drive is transferring files.

The front of the drive is relatively unadorned. Its curved surface does look like the spine of a book, with a single white led near the center for power/disk activity duties. A chromed Western Digital logo shines just above the base of the drive. Other drives like the Western Digital My Book Studio II and the Seagate Backup Plus Desktop Drive for Mac (3TB) have LED indicators that tell you when they are filling up. The My Book has a simple, single LED, which is sufficient. On the back, you'll find a USB 3.0 mini-b connector for the included cable, plus a jack for the AC adapter, and another for a Kensington lock. You can use the drive with older USB 2.0-only PCs, but of course file transfers will take (a lot) longer under USB 2.0. A power button and some identifying labels round out the back panel. That's pretty much all you need, although a capacity/use indicator is a nice touch on the other drives.

The drive's 4TB capacity is relatively unaffected by the included software. The drive's manuals, WD SmartWare, and other utilities take up a measly 455MB of the 4000GB drive. SmartWare lets you setup smart backup and recovery of your important files. You can set the software to continuously backup your new and changed files. You can also setup Drive Lock for security, which uses hardware encryption to keep your data safe from prying eyes. The drive comes formatted for NTFS (Windows), but you can reformat it HFS+ for use on a Mac. The drive has a two-year warranty, which is fine for a basic drive like this.

Performance
Unfortunately, the My Book gave us a little bit of trouble running out PCMark7 and PCMark 05 tests, so we can't report on those results. However, the drive was able to complete our standard drag-and-drop copy test, which came in at a quick 10 seconds to copy our 1.2GB test folder. This was faster than the My Book Studio II under eSATA, as well as our Editor's Choice IoSafe Solo G3 (1TB) ($299 direct, 4.5 stars). This means that the drive will be very quick in the sort of backups and file copies that most users will expect. It is certainly faster (when used with a USB 3.0-equipped PC) than that old USB 2.0 drive you have on your desk, which will take upwards of 40 seconds to copy the same folder. The drive is quick, but not made for constant use.

Compared with the competition, the Western Digital My Book (4TB) is a very good hard drive, with a good bang for the buck and a simple mission: keep your data safe. It's not quite as secure as the smaller-capacity IoSafe Solo G3, which holds on to its Editor's Choice status due to its robust physical ruggedness and included data recovery voucher. It's also much, much slower than the LaCie Little Big Disk Thunderbolt, which is our other Editors' Choice for hard drives. The LaCie is best suited for the media pros that constantly run their hard drives over the course of a 12-16 hour day. Call the My Book for what it is: a good, well built, and capacious hard drive that will keep most users happy when used for manual or automatic backups and for file transfers part time.

COMPARISON TABLE
Compare the Western Digital My Book (4TB) with several other hard drive side by side.

Why Did Google Buy BufferBox? Because The Entire Mail And Package Delivery System Is Broken

4372183674_874289f939_zToday, Google bought an Ontario-based company called BufferBox. In a way, it kind of came out of left field. Since it's a Google Ventures company, one can guess that those on Google's campus were very familiar with the service, which provides an easy alternative to waiting around for packages at your house. Not only is package delivery a bummer, because things get lost, hitting up your mailbox when you get home isn't that much fun either. The worst is when you don't even have a mailbox and you come home to twenty pieces of junkmail slipped under your door. The mail delivery system is broken and old. It's ripe for...disruption.

Joshua Stanton: Human Hand in Sacred Texts

The word "sacred" is applied so ubiquitously that its meaning is seldom consistent, even from one conversation to the next. Why is something sacred? Where is the sacred? When is it sacred? And the most difficult question for many of us who ascribe to a religious tradition, who or what is sacred?

When trying to explain how the term applies to particular texts or Scriptures, many people fall back upon a series of clich?s and euphemisms. I will admit to using more than a few of them myself. Something about the nature of the sacred, as we see it in written form or hear elements of it conveyed through oral tradition, can create ambiguity in our use (and even understanding) of the term. It can be difficult to pinpoint exactly what makes a text sacred.

One of the underlying questions that may be a cause for confusion is whether the "sacred" part of our texts comes from the belief that their content and form originate apart from human beings (and instead, with God or in a Divine realm) or with human beings (who themselves have elements of "sacredness" and channel the sacred through a particular text). Conceptions of prophecy and the conveyance of religious text amplify the disparities in our understanding of what "sacred" truly means in relation to the words we hold dear.

To put a finer point on this challenging term, what is it, from the standpoint of respective adherents, that sets apart the Torah, Quran, Bible, Bhagavad Gita, Guru Granth Sahib, or any other text in which one senses the sacred, from the countless other writings in the human canon of narrative?

Tugging at us are the competing forces of universalism and particularism. Is our text distinct from others because the Divine has designated it the sole or central source of ultimate meaning? Is it but one of many works in a spectrum of Divine writings? Or, as I am increasingly coming to think, is a text sacred because of the extent to which the Divine (or as I would put it, the Ordering Force of the Universe) is animated by the human process through which it is discerned?

Though I cannot speak with adequate knowledge about the process of exegesis and interpretation within other traditions, I find beauty to an extent that I would term "sacred" in the rabbinic process. It is this process that defines for me how the Torah is to be understood and gives meaning to the term "sacred" as extrinsic to the written text itself, irrespective of one's views about its intrinsic nature or purveyance. Such is the beauty of the rabbinic process that my questions about the origins of the Torah become secondary to the pursuit of truths evident therein.

If words of the Torah were cloth, the rabbinic tradition unweaves the vestment of our religious text, holds with care the fabric of our narratives and reweaves them with the unmistakable precision of the ethicist, venturing to derive and apply universal values. The new garments are never fully complete, but are woven and rewoven, honed and embellished upon, and personalized by each thinker who delves into rabbinic discussion. Each joins in the rabbinic process seeking to weave his or her own garment of Torah, sacred clothing that approximates truth as one understands it.

Through the process of rabbinic debate and discussion, we become bearers of the intellectual garments that have been passed along and refashioned throughout the centuries. We sew ourselves into the cloth that our intellectual ancestors bestowed upon us. It adorns our humanity.

Debates at times become furious, abrasively reshaping presupposed designs of fabric, and at other moments are softened, providing for a new tassel or stitching anew fabric that transcend time.

In venturing into the eternal weaving and unweaving of sacred text, we ourselves are woven into the fabric of a tradition so ancient that we cannot possibly know its origins with certainty. The question of Divine provenance becomes secondary to the very human and iterative process by which we engage and make evident the sacred in ourselves and our lives.

Humans sanctify themselves not in the passive resonance they feel with stories that transcend time, but in the active engagement and re-crafting of these stories through the questioning of premises, derivation of overarching truths, and a willingness to unweave and reweave these initial narratives in forms that more closely resemble that which we understand to be ultimate meaning.

The sacred, as I see it in the text that is central to my life, is evoked not merely by the text itself, but by the human interaction with it. Whether our religious texts were created by God or by an unending line of thinkers who stitched their earliest forms, it is the human hand that often makes evident the sacredness within them.

This article represents only my own views and does not reflect the positions held by Hebrew College, the Journal of Inter-Religious Dialogue, or any other organizations of which I am a part.

Paintball Tips, Paintball Accessories - What Is Paintball

A paintball is a capsule of vegetable oil based dye, which comes in different colors and variations. It is used in a military type combat games consisting of teams. The players of the team have to eliminate the opposing players by shooting these paintballs at them. When a paintball hits a player he gets eliminated.

Paintballs are made in a unique way. They are basically gelatin capsules, which contain colored liquid. This paint or color liquid is safe as it is non-toxic, water soluble and biodegradable.

Paintballs weigh only a few grams and measure only 1.7 cm in diameter. When they hit a person, they burst and leave a splatter of paint on the person. The size of this splatter is about 13 cm.

Players use gas powered guns to shoot paintballs at each other. The use of paintballs provides the players with real time atmosphere and situations.

The history of Paintball
The history of paintball can be traced back into the early 1970s. During this period paintball guns were mainly used as a tool for marking livestock and tress. Then in 1981, some 12 friends introduced paintball as a recreational game. They used industrial paintball guns. These twelve friends played this game for the first time on a field of over 100 acres. The game paintball was originally named as the national survival game.

There are continuous innovations happening in the construction of new games and fields of paintball.

With the growing number of paintball fans the paintball industry is also blooming. They are developing commercial paintball fields. In 1982, the first commercial outdoor paintball field was developed. Since then developments of new fields have kept paintball enthusiasts coming back for more fun and excitement.

Today there are prizes set up by organizations for the winning teams. The players keep on updating their paintball guns, with the advent of newer technologies.

The basic thing which sets this game apart from other games is the type of equipment involved. Not too many games involve such adept use of guns.

The famous paintball games
Since the advent of paintball as a game, people and industries have both developed new style of game combating. But there are some famous paintball games that are played and enjoyed by paintball enthusiasts.

Capture the flag
It is a classic paintball game. This game includes two opposing teams. The teams have to acquire the opponents flag and hang their flag on a designated location. During this process, the players of the either team have to protect their own flag.

When this game is played in tournaments, it requires skills and intelligence. If a team eliminates all the players of the opposition, having none of their players eliminated and hangs the flag within the allotted time, they are said to have maxed the opposition. The term maxed implies that they have scored the maximum possible points that could be achieved in the game.

Center flag
This paintball game is similar to capture the flag. There is only one difference. The flag to be captured is hung in the centre of the field. The teams have captured that flag and hang it on a designated location. This designated location is somewhere on the opposition base.

Elimination
This paintball game requires that the elimination of all the members of the opposition. The objective of the teams is to hit the players of the opposing team and get them all eliminated. Whichever team eliminates all the players of the opposing team wins the game.

Paintball has emerged as game of wits and strategies. It is becoming popular all over the world and is gaining an ever-growing fan base.
