The role of cognitive operations in reality monitoring: a study with healthy older adults and Alzheimer’s-type dementia

Posted by in categories: biotech/medical, life extension, neuroscience

J Gen Psychol. 2009 Jan;136:21–39. doi: 10.3200/GENP.136.1.21–40.

The authors examined the role of cognitive operations in discriminations between externally and internally generated events (e.g., reality monitoring) in healthy and pathological aging. The authors used 2 reality-monitoring distinctions to manipulate the quantity and quality of necessary cognitive operations: discriminating between I performed versus I imagined performing and between I watched another perform versus I imagined another performing. Older adults had more difficulty than did younger adults when discriminating between memories in both versions of the task. In addition, older adults with Alzheimer’s-type dementia showed marked difficulties when attributing a source to imagined actions. The authors interpret these findings in terms of an age difficulty or the failure to use cognitive operations as useful cues during source monitoring.

Colorado’s first drive-up COVID-19 testing facility opens in Denver, is free of charge

Posted by in category: biotech/medical

DENVER – Colorado’s first drive-up testing facility for the novel coronavirus (COVID-19) opened Wednesday in Denver’s Lowry neighborhood and saw several dozen vehicles in line after it opened.

The drive-up facility, located at 8100 E. Lowry Blvd. in Denver, will be open from 10 a.m. to 2 p.m. Wednesday through Friday, and next week’s schedule will be posted on the state’s website once the schedule is decided.

Chinese Robot Is Designed to Help Doctors Fight Coronavirus

Posted by in categories: biotech/medical, robotics/AI

Chinese researchers have developed a robot designed to help doctors treat the new coronavirus and other highly contagious diseases.

The machine has a long robotic arm attached to a base with wheels. It can perform some of the same medical examination tasks as doctors. For example, the device can perform ultrasounds, collect fluid samples from a person’s mouth and listen to sounds made by a patient’s organs.

Cameras record the robot’s activities, which are controlled remotely so doctors can avoid coming in close contact with infected patients. Doctors and other medical workers can operate the machine from a nearby room, or from much farther away.

Mapping Bacterial Neighborhoods in the Gut

Posted by in categories: biotech/medical, genetics, neuroscience

Over many years, the Mazmanian laboratory has described how Bacteroides fragilis in the gut produces beneficial molecules that protect mice from inflammatory bowel disease and autism-like symptoms. Like a densely populated city, a vast majority of the B. fragilis in the gut live within the central part of the intestinal tube, called the lumen. However, the Mazmanian laboratory discovered in 2013 that some B. fragilis reside in the bacterial equivalent of small towns, nestled into microscopic pockets within the tissue walls lining the tube. These sparse populations are protected by mucus and are largely unaffected by antibiotics, suggesting that they act as population reservoirs that ensure long-term colonization.

“For humans, where we live can dictate how we behave—for example, a person living in a city likely has a different everyday life than a person living in a small rural community,” says former graduate student Gregory Donaldson (PhD ‘18), the first author on the new paper. “For the bacteria that we study, the intestines represent their entire world, so we wanted to know how differently they behave depending on how far away from the intestinal surface they are.”

Though they may live in different habitats within the gut, these B. fragilis populations all have the same genetic code. What may differ, however, is how they express those genes—is a bacterium expressing a gene for replication and division, for example, or perhaps for an enzyme that digests food? Donaldson aimed to measure and compare gene expression in these two populations (intestinal wall tissue and lumen of the gut) to determine what, if any, differences were seen.
