...heart attack. During a fierce fire fight in which Lieut. Raul Jimenez Salazar was killed, another hostage, Agriculture Minister Rodolfo Munante Sanguinetti, had a close call. A guerrilla dashed into the room where he was hiding with several others and raised his rifle. But he did not pull the trigger. "He just left without shooting or lobbing a grenade at us," Munante recalled. "I got the impression the boy suddenly felt bad about what he and the rebels had done." Fujimori, his voice breaking, praised Jimenez later for his leadership, saying, "He was the first to open...
...since, evidence linking dopamine to drugs has mounted. Amphetamines stimulate dopamine-producing cells to pump out more of the chemical. Cocaine keeps dopamine levels high by inhibiting the activity of a transporter molecule that would ordinarily ferry dopamine back into the cells that produce it. Nicotine, heroin and alcohol trigger a complex chemical cascade that raises dopamine levels. And a still unknown chemical in cigarette smoke, a group led by Brookhaven chemist Joanna Fowler reported last year, may extend the activity of dopamine by blocking a mopping-up enzyme, called MAO B, that would otherwise destroy...
...degree to which learning and memory sustain the addictive process is only now being appreciated. Each time a neurotransmitter like dopamine floods a synapse, scientists believe, circuits that trigger thoughts and motivate actions are etched onto the brain. Indeed, the neurochemistry supporting addiction is so powerful that the people, objects and places associated with drug taking are also imprinted on the brain. Stimulated by food, sex or the smell of tobacco, former smokers can no more control the urge to light up than Pavlov's dogs could stop their urge to salivate. For months Rafael Rios lived in fear...

"With all due respect, I believe you are misinterpreting the statute," he said. ?All of the persons or entities under investigation have strong ties to the inner circles of the White House...
...Depressing news about depression. A 29-year study finds that CLINICALLY DEPRESSED adults may face a 50% increased risk of dying from stroke. Depression--which is treatable--may somehow alter blood-platelet activity, which in turn may trigger clot formation...
