Exercises improve mobility

A Cochrane review showed that stroke patients who participate in a post-stroke walking program walk faster, longer and more independently than non-exercisers.

“Cardiorespiratory training, which used walking as the mode of exercise, can improve walking ability,” said lead author David Saunders, University of Edinburgh, Scotland.
During the study, researchers looked at 24 studies that included 1,147 stroke patients. The analysis focused on how participation in fitness training programmes after stroke influenced rates of death, dependence or disability.

Fitness training included cardiovascular exercise (walking or cycling), strength training (free weights or resistance bands) or a combination of cardiovascular and strength training. The participants walked three or more days per week, usually for more than 20 minutes at a time.

In exercising patients, maximum walking speed increased by about 5.6 yards per minute, and patients could cover an additional 42.5 yards in a six-minute session compared to non-exercisers.

Drug-light combo against neck cancer
A combination of medications and a particular light therapy has been found to be effective in treating certain types of head and neck cancers. During a study, researchers focused on the use photodynamic therapy (PDT) in tropical climates. The treatment uses a drug called a photosensitizer, or photosensitising agent, and a particular type of light.
The findings revealed that organ preservation and cancer cure can be achieved in patients with recurrent cancer that is superficially spread in the head and neck, but not deeply infiltrated.

Polymer delivers genetic medicine
Scientists have developed a novel molecule that can travel into cells, deliver genetic cargo, and pack a beacon so that scientists can follow its movements in living systems.
This advancement is a result of the efforts of Theresa M Reineke, University of Cincinnati. “My lab has been trying to find a way to deliver genetic-based drugs into cells,’ she said.
While studies being conducted across the world are using information from the human genome project as an approach to treat disease, Reineke’s focus is cancer and cardiovascular disease.

“Traditional drugs are aimed at treating disease at the protein level. Genetic drugs — such as those that can alter or control gene expression — aim to treat disease at the genetic level and have the added benefit of being more specific for their medicinal target,” she said. The scientists created novel polycations, a polymer chain with positive charges, which is not too unusual.

Effects of violent upbringing
Individuals who have experienced violence at an early age may have trouble adjusting to healthy, adult romantic relationships, says a new study. The research reveals that early exposure to a violent environment is likely to lead to domestic violence situations later in life. Feelings of insecurity, abandonment anxiety, and intimacy issues are also likely to plague these romantic connections. Additionally, the dynamics of the way couples react and communicate with each other is also related to the likelihood of domestic violence within a relationship.
