Fish Oil And Weight Control

Published

on

New research has found that fish oil can transform fat-storage cells into fat-burning cells, which may help reduce weight gain in middle age.
According to the study in Nature Scientific Reports, fish oil activates receptors in the digestive tract, and triggers activity in the sympathetic nervous system that induces specific type of fat cells to metabolise fat.
Fat tissues don’t all store fat. So-called “white” cells store fat in order to maintain energy supply, while “brown” cells metabolise fat to maintain a stable body temperature. Brown cells are abundant in babies but decrease in number with maturity into adulthood.
Normally, humans have three types of fat cells, white, brown and the newly discovered beige cells. Brown and beige cells metabolise fat for temperature control while white cells store fat for energy. The number of brown and beige cells decline as we get older.
However, Japanese researchers have found that consuming more fish oil can help  turn white storage cells  into beige metabolising cells and contribute to weight loss.
A third type of fat cell – “beige” cells – have recently been discovered in humans and mice, and have shown to function much like brown cells. Beige cells also reduce in number as people approach middle age; without these metabolising cells, fat continues accumulating for decades without ever being used.
The scientists investigated whether the number of these beige cells could be increased by increasing intake of fish oils.
“We knew from previous research that fish oil has tremendous health benefits, including the prevention of fat accumulation,” says senior author Teruo Kawada. “We tested whether fish oil and an increase in beige cells could be related.”
The team fed one group of mice fatty food, and four other groups received fatty food with four different types of fish oil enriched with either low or high dose DHA (docosahexaenoic acid) or low or high dose EPA (eicosapentaenoic acid). Whatever type of fish oil they were supplemented with the mice in those groups gained 5-10 percent less weight and 15-25 percent less fat compared to those that did not consume any oil.
Both the DHA and EPA rich oils produced similar results and the scientists speculate that if combined they could have a more potent synergistic effect.
The study also found that beige cells formed from white fat cells when the sympathetic nervous system was activated, meaning that certain fat-storage cells can shift from storage cells to metabolising cells.
Although this was an animal study it points the way towards our understanding of how different aspects of diet can help or hinder health.
“People have long said that food from Japan and the Mediterranean contribute to longevity, but why these cuisines are beneficial was up for debate,” says Kawada. “Now we have better insight into why that may be.”

‘How Micro RNA Research Won Nobel Prize’

Published

on

Two United States scientists who unraveled the human micro RNA have won the Nobel Prize in Physiology or Medicine 2024.
Victor Ambros and Gary Ruvkun won the coveted  prize for their work on microRNA as their discoveries help explain how complex life emerged on earth and how the human body is made up of a wide variety of different tissues.
MicroRNAs influence how genes – the instructions for life – are controlled inside organisms, including humans.
Every cell in the human body contains the same raw genetic information, locked in our DNA.
However, despite starting with the identical genetic information, the cells of the human body are wildly different in form and function.
The electrical impulses of nerve cells are distinct from the rhythmic beating of heart cells. The metabolic powerhouse that is a liver cell is distinct to a kidney cell, which filters urea out of the blood.
The light-sensing abilities of cells in the retina are different in skillset to white blood cells that produce antibodies to fight infection.
So much variety can arise from the same starting material because of gene expression.
The US scientists were the first to discover microRNAs and how they exerted control on how genes are expressed differently in different tissues.
The medicine and physiology prize winners are selected by the Nobel Assembly of Sweden’s Karolinska Institute.
They said: “Their groundbreaking discovery revealed a completely new principle of gene regulation that turned out to be essential for multicellular organisms, including humans.
“It is now known that the human genome codes for over 1,000 microRNAs.”

WHO Begins Regulation On Antibiotic Waste

Published

on

The World Health Organisation (WHO) has begun acting to curb effects of antibiotic pollution.
The new guidance on wastewater and solid waste management for antibiotic manufacturing sheds light on this important but neglected challenge ahead of the United Nations General Assembly (UNGA) High-Level Meeting on antimicrobial resistance (AMR) taking place on 26 September 2024.
The emergence and spread of AMR caused by antibiotic pollution could undermine the effectiveness of antibiotics globally, including the medicines produced at the manufacturing sites responsible for the pollution.
Despite high antibiotic pollution levels being widely documented, the issue is largely unregulated and quality assurance criteria typically do not address environmental emissions. In addition, once distributed, there is a lack of information provided to consumers on how to dispose of antibiotics when they are not used, for example, when they expire or when a course is finished but there is still antibiotic left over.
“Pharmaceutical waste from antibiotic manufacturing can facilitate the emergence of new drug-resistant bacteria, which can spread globally and threaten our health. Controlling pollution from antibiotic production contributes to keeping these life-saving medicines effective for everyone,” said Dr Yukiko Nakatani, WHO Assistant Director-General for AMR ad interim.
Globally, there is a lack of accessible information on the environmental damage caused by manufacturing of medicines.

 

“The guidance provides an independent and impartial scientific basis for regulators, procurers, inspectors, and industry themselves to include robust antibiotic pollution control in their standards,” said Dr Maria Neira, Director, Department of Environment, Climate Change and Health, WHO. “Critically, the strong focus on transparency will equip buyers, investors and the general public to make decisions that account for manufacturers’ efforts to control antibiotic pollution.”

Kebbi Harmonises Doctors’ Salaries To Curb Brain Drain

Published

on

In a concerted effort to curb brain drain, the Kebbi State Government has harmonised medical doctors’ salaries to be at par with their colleagues in the federal government’s tertiary health facilities.
Kebbi State Commissioner for Health, Musa Inusa-Isma’il, disclosed this at the handing over of ambulances to the state-owned health facilities at the Ministry of Health in Birnin Kebbi yesterday.
Inusa Isma’il, according to a statement by Ahmed Idris, the Chief Press Secretary to the governor, said the essence of the harmonisation was to retain the existing medical doctors and attract more to the services of the state.
According to him, the doctors across the state had already started enjoying the new salaries from August 2024.
He said the release of the vehicles was in fulfilment of Governor Nasir Idris’ promise to uplift health care services in the state.
“His Excellency said I should inform you, the beneficiaries of this gesture, that the vehicle should be strictly used for the intended purpose. It should not be used for anything else.
“If there is no referral case, each of the vehicles must be parked at the hospital by 6 pm. The governor said you should warn your drivers against reckless driving as well as violating the instructions.
“We should also do everything possible to reciprocate the gesture by working according to the terms and conditions attached,” he advised.
The benefiting health facilities included Sir Yahaya Memorial Hospital, Birnin Kebbi; State Teaching Hospital, Kalgo; General Hospital, Argungu; General Hospital, Yauri; General Hospital, Zuru; and General Hospital, Bunza.

 

 

In his speech, the permanent secretary of the ministry, Dr Shehu Koko, recalled that the ambulances were handed over to the ministry last Friday by the governor for the onward handover to the benefiting hospitals.
He observed that the ambulances would go a long way in improving the referral system in the state, adding that delays in reaching the secondary and tertiary facilities would be eliminated.
The permanent secretary attributed the high rate of maternal mortality in the country to delays in getting to the health facilities for proper medical care.
“We believe with the provision of these ambulances, part of the gaps we have in our referral system will be addressed, whereby patients who require secondary healthcare could be easily transported to secondary and tertiary health centres, where they can get such help,” he said.
In a goodwill message, Commissioner for Information and Culture Alhaji Yakubu Ahmed expressed gratitude to the governor for the support he has given to the ministry to excel.
While advising the beneficiaries to use the vehicles judiciously, the commissioner advised that services and maintenance of the vehicles must be prompt to derive the maximum benefits from the vehicles.
The commissioner also highlighted some achievements recorded by the government in the last year, including beautification of the state capital, completion of a multimillion-naira ultramodern state secretariat, road construction, construction and renovation of classrooms and upgrading of some health facilities, among others.
