Background: Targetable molecular drivers of gastric cancer (GC) metastasis remain largely unidentified, leading to limited targeted therapy options for advanced GC. We aimed to identify molecular drivers for metastasis and devise corresponding therapeutic strategies.

Methods: We performed an unbiased in vivo genome-wide CRISPR/Cas9 knockout (KO) screening in peritoneal dissemination using genetically engineered GC mouse models.

Background: The Omicron variant has become the most prevalent SARS-CoV-2 variant. Omicron is known to induce milder lesions compared to the original Wuhan strain. Fatal infection of the Wuhan strain into the brain has been well documented in COVID-19 mouse models and human COVID-19 cases, but apparent infections into the brain by Omicron have not been reported in human adult cases or animal models.

Article Synopsis
  • COVID-19 severity ranges from mild to fatal, linked to immune system dysfunction, specifically lymphoid depletion and low lymphocyte counts.
  • Research using hACE2 transgenic mice showed that severe COVID-19 leads to significant lymphoid tissue depletion and impaired antigen-presenting cell (APC) function, correlating with increased mortality.
  • Findings indicate that these immune changes are unique to SARS-CoV-2 and suggest that improving APC functionality could be a potential treatment strategy for severe COVID-19 cases.

The purpose of this study was to investigate changes in dynamic balance and gross motion function when dual-task training was performed on an unstable support surface by children with spastic diplegia. The subjects of this study were 14 children (experimental group n=7, control group n=7) who were medical diagnosed with spastic diplegia. Both groups were administered treatment for 30 min, 2 times a week for 8 weeks, with the experimental group performing dual-task exercise in which cognitive tasks related to daily living were performed while maintaining balance on an unstable surface, and the control group being administered neurodevelopmental treatment.

[Purpose] The purpose of this study was to investigate the impact that modified constraint-induced movement therapy has on upper extremity function and the daily life of chronic stroke patients. [Subjects and Methods] Modified constraint-induced movement therapy was conduct for 2 stroke patients with hemiplegia. It was performed 5 days a week for 2 weeks, and the participants performed their daily living activities wearing mittens for 6 hours a day, including the 2 hours of the therapy program.

Purpose: In South Korea, as growing the need of psychological support in disaster situation psychological assessment on stress after disaster is important to find out the factors affecting coping, and to plan intervention in the community.

Method: The volunteers of Korea Redcross who live around K city, and the research team visited all homes at Jirye town, one of the high-impact area, 4 month after the typhoon. One of the family members who is over 18 years old, answered the self-report questionnaire composed of disaster experience, damage, exposure to traumatic event, and posttraumatic stress with IES-K (Impact of Event Scale-korea) He also, described his family members symptom related to re-experiencing, hyper-arousal, and avoidance.
