Getting Acquainted With the Various Kinds of Surveillance Technology
The advancements in surveillance technology have led to the introduction of innovative audio and video recording equipment for personal and professional use. You can purchase everything from an audio recorder that will fit in your hand, to a video recorder that can easily be concealed and accessed online.
Surveillance technology takes in numerous types of applications and devices. These tools used for your protection and safety can be used inside or out. They can be portable instruments that are used at several locations or they can be devices that remain stationary.
One type of surveillance technology that is commonly used by both homeowners and business owners is a device that makes it possible to record or transmit audio or video information. You can decide which type is more useful to you. When it comes to the security of your home or business, you can never be too careful.
Recording devices or video cameras used for surveillance are generally used to make sure that nothing illegal or inappropriate is taking place on the premises. These security items are often hidden from sight. To do anything else would defeat the purpose of them. The prices for audio and video equipment can vary by brand name. In most cases, they can have a costly price tag. You can find equipment that comes with numerous types of features. Decide what is most important to you in terms of features before you start your shopping.
It may be your external environment that requires surveillance technology, and not the internal area of your house or workplace. For your external surroundings, small hidden cameras can be strategically placed to monitor specific sections of the property. These cameras make use of digital video recording (DVR) in order to capture video images. This allows for an easier system of transmission. It also makes for easier storage and portability.
If you look around, you will find plenty of places where a small recording device can be concealed. Some examples of these include trees, lamps, benches and posts. You might even be able to place one inside of your satellite dish. This type of security measure is often designed to be motion activated. The way it works is that the instrument starts to record as soon as it detects motion in the nearby vicinity.
While outdoor surveillance equipment is popular to keep watch over a residence or a business, indoor systems have also gained in popularity. Concealed cameras and video recording equipment, sometimes referred to as ?nanny cams?, are very beneficial for those people who have babysitters coming into their homes to look after their children.
Nanny cams can be hidden almost anywhere and they can go a long way in protecting your youngsters. Those who suspect a problem with their employees may decide to use one in order to catch a person in the act of doing something wrong.

Immune system changes may drive aggressiveness of recurrent tumors
Dec. 26, 2012 ? Nearly half of the 700,000 cancer patients who undergo surgical removal of a primary tumor each year suffer a recurrence of their disease at some point, and many of those patients will eventually die from their disease. The traditional view of recurrent tumors is that they are resistant to therapy because they've acquired additional genetic mutations that make them more aggressive and impervious to drugs. Now, however, researchers at the Perelman School of Medicine at the University of Pennsylvania show in an animal model that the enhanced aggressiveness of recurrent tumors may be due to changes in the body's immune response.
The findings are published this week in the Proceedings of the National Academy of Sciences.
"Typically when a patient has a tumor recurrence, their oncologist treats them, much like they treated them for the primary tumor -- with drugs aimed at the tumor cells themselves. But we've found that it might be better to attack the tumor cells and knock down the bad immune cells that are protecting the tumor," says senior study author Sunil Singhal, MD,assistant professor of Surgery and director, Thoracic Surgery Research Laboratory at the Perelman School of Medicine.
To assess the impact of anti-cancer vaccines on primary and recurrent tumors, the researchers immunized mice that had a primary or a recurrent tumor in their flank. Although both groups of animals developed an immune response to the vaccine, only the primary-tumor animals showed tumor shrinkage in response to the vaccine. The recurrent tumors appeared unaffected by the vaccine response. Moreover, this pattern held for several different vaccines.
Despite the prevailing models of tumor recurrence -- which emphasize genetic changes in the tumor cells themselves -- Singhal and colleagues could not find substantial genetic or behavior differences in the recurrent versus primary tumors that might account for the pattern of response.
By contrast, when the team looked at the types of immune cells in and around the tumor, Singhal's team saw a big difference. The recurrent-tumor mice had a large increase in the number of regulatory T cells, compared with primary-tumor animals. That could be important, says Singhal, because T regulatory cells are responsible for holding other immune cells in check and blocking immune responses.
Additionally, macrophages that protect the tumor cells from immune system also increased in number and activity in the recurrent-tumor animals.
Remarkably, when the researchers treated recurrent-tumor animals with drugs that block macrophage activity, tumor growth slowed significantly. However, the same drugs had no effect on primary-tumor animals.
Singhal says it is not clear exactly what triggers the immune system changes, but whatever it is appears to happen at the time of surgery. His group has already started looking for alterations in signaling molecules.
In the meantime, though, he notes that there are newly approved drugs and experimental agents that block regulatory T cells. Given his team's new results, he thinks testing these agents in patients with recurrent disease -- in combination with drugs that attack the tumor cells themselves -- could be an important advance for patients.
"We could impact the outcomes of as many as 250,000 patients a year, if this strategy works," he said.
Other authors from Penn include first author Jerrod Predina and co-authors, Evgeniy Eruslanov, Brendan Judy, Veena Kapoor, Guanjun Cheng, Liang-Chuan Wang, Jing Sun, Edmund K. Moon, Zvi Gregorio Fridlender, and Steven Albelda.
Funding for the study came from a National Institutes of Health Paul Calabresi Scholarship, the Lavin Family Foundation, and the National Lung Cancer Partnership.

MWN Shares its Success Story in Casablanca's School of Journalism
By Loubna Flah
Morocco World News
Casablanca, December 27, 2012
The Casablanca-based Ecole Superieure de Journalisme et de Communication (School of Journalism and Communication) on Wednesday invited Dr. Samir Bennis, co-founder and editor-in-chief of Morocco World News to share its experience with the young students of the school.
Samir Bennis shared with the audience the story behind the creation of Morocco World News. Being a strong advocate of Morocco?s territorial integrity, especially regarding the Sahara region, Mr. Bennis decided along with his brother, Mr. Adnane Bennis, to set up a new platform that would provide international public opinion with a more balanced and nuanced vision on the? Sahara issue. He highlighted that there is lack of awareness among the Moroccan public opinion and media professionals about the need to reach out to the international public opinion in order to provide it with a more nuanced and balanced vision about Morocco.

He added that MWN intends to be Morocco?s window to the world, thus providing any person eager to learn about the country to have access to information covering every aspects of its culture, history, economic and political life.
He went to on to stress the pivotal role played by MWN in the media landscape both at the domestic and the international levels, especially in the United States. It has indeed lifted the veil of silence over deficiencies in defending Moroccan interests before the international community.
He also highlighted that MWN is the only Moroccan news outlet that provides news and analyses about Morocco and the rest of the world around the clock, while commending the other members of the team located in Morocco, who play an important role in providing the readers with the latest news about the event taking place in the MENA region.
Dr. Samir Bennis in Casablanca's School of Journalism, talking about the success story of www.moroccoworldnews.com
Mr. Bennis listed a number of crucial events that have traits with Morocco?s sovereignty over the Sahara region exclusively covered by the MWN team. He referred to the omission of the Sahara region from the documents submitted by the Morocco Mall architecture company. In addition, MWN was the first news outlet to address the lack of coverage by Moroccan media of the Security Council sessions in New York where the Sahara conflict is debated.
In this regard, Mr. Bennis had sent an open letter to the minister of communication Mr. Khalfi. He seized the opportunity to call for reform of the media sector in regard to national interests. The same issue was raised during an MWN interview with Mr. Choubani, minister in charge of relations with parliament and civil society.
Mr. Bennis shared with the audience the long term goals of MWN. Indeed, MWN founders envision building an influential news outlet that will rival with major international news outlets.
He highlighted that MWN emerged as a groundbreaking English speaking news outlet that provides insight to both local and international news in total alignment with Moroccan identity and supreme national interests. He added that the appeal of MWN is going crescendo, pointing out that readers from an average of 90 countries visit the website every day.
He also highlighted that, unlike other news outlets in Arabic or French whose reach is limited, MWN has further reach commensurate to the global reach of the English language.
Dr. Samir Bennis will also be a guest speaker at the University Hassan II of Casablanca on Friday 28 December where he will enlighten the audience of the university about the Spanish colonial legacy and the representation of Moroccans, as well as in Meknes? Moulay Ismail University on Friday 4 January where he will share his experience in launching MWN.
Online journalism is still at the embryonic stage. Yet, this new trend seems to be a bottomless reservoir of unexplored possibilities. MWN ambitious team is resolute to expand its outreach among Moroccan and international readership by maintaining high standards and, most importantly, by being faithful to the national identity.

Doctors on Call: Smoking does more than cause cancer
HOW TO QUIT
Millions of successful quitters have invented lots of creative methods to stop smoking, according to ?Why Quit News,? as printed by Livestrong.com.
Here are the top ways:
Cold turkey
Quitting cold turkey, meaning all at once, instantly transforms you into a non-smoker. Joel Spitzer, director of ?Freedom From Tobacco? in Evanston, Ill., says the cold turkey motto is simply ?Never Take Another Puff.? Spitzer says 91 percent of successful quitters do it cold turkey.
Group support
The American Lung Association recommends quitting with a group of like-minded people. You can support each other, trade winning strategies and swap successful tips. The most successful groups are conducted by trained, experienced leaders.
Hypnosis
In a 2009 report by physicians at the American Cancer Society, hypnosis helped some people quit smoking, but techniques, practitioners and success rates vary widely. Coaches at Smoking Cessation.org report a 66 percent success rate with a four-session protocol administered by licensed psychologists.
Replacement
Nicotine replacement therapy, or NRT, replaces cigarettes with patches, gums, nasal sprays, lozenges or inhalers. These enable tapering off the addictive nicotine so you can manage your cravings in gradual steps, while eliminating smoke and its other harmful chemicals from your lungs.
Sabotage
Sabotage your habit. The American Lung Association advises quitters to prepare by tossing out their ashtrays, lighters and matches. Also, eliminate triggers like coffee and alcohol from your pantry, then buy tea and other beverages. Remove every cigarette from your home. Without tobacco and its paraphernalia, you cannot smoke.
Phone a friend
The American Cancer Society says all U.S. states and the District of Columbia provide free telephone links to trained counselors who match programs to individuals? needs. Phone counseling is twice as effective as quitting without help. Florida?s phone program can be reached at (877) 822-6669, while Georgia?s is at (877) 270-7867.
Zyban
Bupropion, brand named Zyban, reduces nicotine withdrawal symptoms. It can be prescribed alone or with NRT. Start one or two weeks before quitting tobacco. Do not use Zyban if you have seizures, serious head injury, bipolar or eating disorders, or a tendency to abuse alcohol.
Chantix
Varenicline, brand named Chantix, interferes with brain receptors for nicotine, diminishing the enjoyment of smoking, and reducing nicotine withdrawal symptoms. The ACS reports that several studies have shown varenicline more than doubles success rates for smoking cessation. Other studies suggest better short-term effectiveness than with bupropion.
Nicotine Anonymous
This is a 12-step program for living nicotine-free. Nicotine Anonymous offers group support along with the ?12 Steps? approach pioneered by Alcoholics Anonymous. The toll-free number is (877) 879-6422 for printed materials, information and meeting schedules.
Follow the money
The American Lung Association says to reward yourself for quitting. The average cost of a pack of cigarettes in Florida is $6 per pack. Smoking a pack a day would cost $2,184 per year. If you think about what else you can buy with that, you will probably find a way to stop smoking.
