Research shows Heat therapy could boost mitochondrial function in muscles

A new study described as first of its kind in humanity, finds that long-term heat therapy may increase mitochondrial function in the muscles. The discovery could lead to new treatments for people with chronic illness or disease.

Mitochondria, the “energy centers” of the cells, are essential for maintaining good health. A decrease in the number or function of mitochondria may contribute to chronic and potentially serious conditions such as heart disease, chronic obstructive pulmonary disease and type 2 diabetes. Exercise has been shown to create new mitochondria and improve function of existing mitochondria. However, some people with chronic illnesses are not able to exercise long enough — previous research suggests close to two hours daily — to reap the benefits. Rodent studies have suggested that heat exposure may also induce the production of more mitochondria.



Researchers from Brigham Young University in Utah studied 20 adult volunteers who had not participated in regular exercise in the three months prior to the study. The research team applied two hours of shortwave diathermy — a type of heat therapy generated by electrical pulses — to the thigh muscles of one leg of each person every day. The researchers based the six-day trial of heat on the minimum amount of exercise needed to measure changes in muscle, or about two hours each day. They designed the treatment to mimic the effects of muscle heating that occurs during exercise. The therapy sessions increased the temperature of the heated leg by approximately 7 degrees F. Each participant’s other leg served as a control, receiving no heat therapy or temperature change. The researchers looked at mitochondria content in the muscles on the first day of therapy and 24 hours after the last treatment.

Mitochondrial function increased by an average of 28 percent in the heated legs after the heat treatment. The concentration of several mitochondrial proteins also increased in the heated legs, which suggests that “in addition to improving function, [repeated exposure to heat] increased mitochondrial content in human skeletal muscle,” the research team wrote.

“Our data provide evidence to support further research into the mechanisms of heat-induced mitochondrial adaptations,” the researchers explained. People who are not able to exercise for long periods of time due to their health may benefit from [heat] treatments.

Cote d’Ivoire: Destroying the Killer Rice

Published

on

Authorities in Cote d’Ivoire have destroyed 18,000 tonnes of rice declared to be unfit for human consumption.

This follows tests carried out by the country’s consumer association which had demanded the government to do so after the cargo from Myanmar had been refused entry in Togo, Guinea and Ghana over quality issues.

The national and international quality control tests revealed the unfit nature of the rice.

It should be noted that most African countries depend on imports because local farmers are unable to meet the ever rising demands.

Mali: Donkeys deliver vaccines as diseases spike with violence

Published

Reuters DAKAR –

With spiraling ethnic violence exposing more children in Mali to fatal diseases, health workers are using donkeys and boats to deliver life-saving vaccines, charities said on Wednesday.

In the central Mopti region – where 157 people died in one attack last month – suspected measles cases rose five-fold in one year to 98 in 2018, U.N. children’s agency UNICEF said, due to a four-fold jump in unvaccinated children to 70,000.

Motorcycles, which health workers used to reach remote villages, have been banned to reduce militant activity, forcing them to use traditional means like horses, it said.

“The problem of vaccination is directly linked to the current conflict,” said Patrick Irenge, medical coordinator for the charity Medecins Sans Frontieres (MSF), which is using cars and boats as mobile clinics to reach cut off communities.

“If there is a lull in the violence, a small window that opens, we organize a vaccination campaign.”

Last month’s massacre was the deadliest to date in a conflict between Dogon hunters and Fulani herders which has displaced tens of thousands of civilians in the West African country since it escalated last year.

Pneumonia is one of the top killers of children in Mali and it can be prevented with vaccines – as can measles – but it is too dangerous for many parents to venture out with children.

“Transport is difficult because we don’t have the means to rent a vehicle or a horse cart,” said Aissata Barry, a 34-year-old mother in the village of Kankelena, about 4 km (2.5 miles) from the nearest health center in the town of Sofara.

“There are rapists on the road. That’s what we’re afraid of,” she told the Thomson Reuters Foundation by phone, adding that one of her neighbors was raped two weeks ago.

Mamadou Kasse, a local health worker who vaccinated Barry’s children, said the number of children he can reach each day has fallen since he swapped his motorbike for an eight-hour ride in a donkey cart with a cooler full of vaccines.
