2021-02-09
(Press-News.org) Samara Polytech chemists investigated the potential anticarcinogenic effects of extracts obtained from plant materials of lingonberry, raspberry, black chokeberry, grapes, Krasnodar green tea, ginseng, fireweed and coffee, and also evaluated their effect on the growth and viability of colon cancer cells. The research was carried out within the framework of the state assignment for fundamental research No. 0778-2020-0005, its results were published Dec. 29, 2020 in the journal Proceedings of Universities. Applied Chemistry and Biotechnology (DOI: https://doi.org/10.21285/2227-2925-2020-10-4-613-626).

Prevention is the most cost-effective and long-term strategy for controlling this disease. It is now well known that almost 50% of all malignant tumors can be prevented with proper nutrition based on natural products with a preventive effect.

"Polyphenols are the largest variety of plant components. It is this class of chemical compounds that have shown powerful antioxidant properties. They actively fight against cellular damage caused by free radicals, slowing down the aging and preventing oxidation. In addition, they protect the body from inflammatory, cardiovascular, neurodegenerative diseases, and some forms of cancer", one of the authors of this study, associate professor of the Department of Technology and Organization of Public Catering of Samara Polytech Natalya Eremeeva explains. "We studied in detail the beneficial properties of lingonberry, raspberry, black chokeberry, grapes, Krasnodar green tea, ginseng, fireweed and coffee.

When conducting the MTT cytotoxicity test, the scientists found that the ginseng extract was the most cytotoxic, and the coffee extract was the least cytotoxic. It has been proven that all the studied extracts are able to reduce the expression of pro-inflammatory genes. The most pronounced inhibitory effect on the expression of these genes is possessed by the extracts of chokeberry and fireweed.

The research team supposes that this study may serve as a basis for conducting in vivo experiments to determine anticarcinogenic activity.

INFORMATION:

For reference:

MTT test is a colorimetric test to assess the metabolic activity of cells.

Cytotoxicity is the ability of chemicals to damage tissue cells, including malignant tumors.

New method for asymmetric N,N-acetal synthesis promises advances in drug development

New method for asymmetric N,N-acetal synthesis promises advances in drug development
2021-02-09
A lot of our medicines and other bioactive drugs are based on chemical structures called "enantiomers"-- molecules that are mirror images of each other and are non-superimposable. Notable among them are chiral N,N-acetals contained in diuretic drugs like bendroflumethiazide and thiabutazide, used to treat high blood pressure and edema. Because an enantiomer and its mirror image version often have different biological activities, with only one of them having pharmacological utility, an "enantioselective" or asymmetric synthesis yielding the desired enantiomer in greater amounts is highly desirable. In the case of N,N-acetals, several studies have demonstrated their enantioselective preparation from aldehydes, aldimines, or enamines. However, in all these cases, ...

Case Western Reserve-led team finds that people with dementia at higher risk for COVID-19

2021-02-09
CLEVELAND (Feb. 9)--A study led by Case Western Reserve University researchers found that patients with dementia were at a significantly increased risk for COVID-19--and the risk was higher still for African Americans with dementia. Reviewing electronic health records of 61.9 million adults in the United States, researchers found the risk of contracting COVID-19 was twice as high for patients with dementia than for those without it--while among those with dementia, African Americans had close to three times the risk of being infected with COVID-19 as Caucasians did. In addition, patients with dementia who ...

Peanut allergy affects even more U.S. adults than children

2021-02-09
KEY STUDY FINDINGS INCLUDE: 2.9% of U.S. adults report a current peanut allergy. About one in six adults with a peanut allergy developed it after age 18. Approximately one in five adults with peanut allergy report visiting the emergency department for food allergy treatment each year. Patients who developed their peanut allergy during adulthood are less likely to report having an epinephrine auto-injector prescription than those who developed their peanut allergy during childhood, despite similar frequencies of severe reactions among both groups. CHICAGO --- Peanut allergy affects at least 4.5 million adults in the U.S., many of whom report developing their ...

Phages can anticipate bacteria's location and destroy them before they cause an infection

2021-02-09
Researchers at Baylor College of Medicine and other institutions have identified a novel strategy that can eliminate bacteria in a specific location before they cause an infection. The strategy uses a phage, a virus that infects and destroys bacteria, that can specifically locate in the same place the bacteria live in the gastrointestinal tract. The proximity between phage and bacteria facilitates the phage's attack and subsequent elimination of the bacteria. This strategy has the potential of becoming a game changer in the fight against antibiotic-resistant bacteria ...

Program led by health coaches at primary care clinics helped reduce heart risk

2021-02-09
DALLAS, Feb. 9, 2021 -- Participants in a two-year, lifestyle intervention/weight-loss program provided through health coaches at their primary care center were able to lower their blood sugar and improve their cholesterol levels, according to new research published today in the American Heart Association's flagship journal Circulation Journal. Researchers with the PROmoting Successful Weight Loss in Primary CarE in Louisiana (PROPEL) Trial reported previously that participants also reduced body weight by an average of 5% and note that patients who lost more weight experienced greater improvements in their heart disease risk factors. "Our results demonstrate lifestyle intervention and weight-loss programs can be successful for people in underserved, low-income ...

Coffee lovers, rejoice! Drinking more coffee associated with decreased heart failure risk

2021-02-09
DALLAS, Feb. 9, 2021 -- Dietary information from three large, well-known heart disease studies suggests drinking one or more cups of caffeinated coffee may reduce heart failure risk, according to research published today in Circulation: Heart Failure, an American Heart Association journal. Coronary artery disease, heart failure and stroke are among the top causes of death from heart disease in the U.S. "While smoking, age and high blood pressure are among the most well-known heart disease risk factors, unidentified risk factors for heart disease remain," according to David P. Kao, M.D., senior author of the study, assistant professor of cardiology and medical director at the Colorado Center for Personalized Medicine at the University of Colorado School of Medicine ...

Limiting warming to 2 C requires emissions reductions 80% above Paris Agreement targets

2021-02-09
In 2017, a widely cited study used statistical tools to model how likely the world is to meet the Paris Agreement global temperature targets. The analysis found that on current trends, the planet had only a 5% chance of staying below 2 degrees Celsius warming this century -- the international climate treaty's supposed goal. Now, the same authors have used their tools to ask: What emissions cuts would actually be required to meet the goal of 2 C warming, considered a threshold for climate stability and climate-related risks such as excessive heat, drought, extreme weather and sea level rise? The University of Washington study finds that emissions reductions about 80% more ambitious than those in the Paris Agreement, or an average of 1.8% drop in emissions per year rather than 1% ...

New study finds climate change shrinks and shifts juvenile white shark range

New study finds climate change shrinks and shifts juvenile white shark range
2021-02-09
New research led by Monterey Bay Aquarium reveals that even the revered white shark cannot escape the impacts of a changing ocean. The study, published in Scientific Reports, finds that unprecedented sightings of juvenile white sharks at the northern end of Monterey Bay signal a significant shift in the young white sharks' range. Researchers conclude the northward range shift demonstrates the young sharks are being subjected to a loss of suitable thermal habitat, meaning water temperatures within their preferred temperature range are becoming harder to find. "Nature has many ways to tell us the status quo is being disrupted, but it's up to us to listen," said Monterey Bay Aquarium Chief Scientist Dr. Kyle Van Houtan. "These sharks - by venturing into territory where they have not historically ...

The invisible killer lurking in our consumer products

The invisible killer lurking in our consumer products
2021-02-09
Our consumer products, such as food, cosmetics and clothes, might be filled with nanomaterials - unbeknownst to us. The use of nanomaterials remains unregulated and they do not show up in lists of ingredients. This is a cause of concern since nanomaterials can be more dangerous than COVID-19 in the long term if no safety action is taken: they are tricky to measure, they enter our food chain and, most alarmingly, they can penetrate cells and accumulate in our organs. Nanotechnology is appearing everywhere, to change our daily lives. Thanks to applications of nanotechnology, we can treat many diseases so efficiently that they'll soon be a thing of the past. We also have materials that are 100 times stronger than steel, batteries that last 10 times longer than ...

New factor in the carbon cycle of the Southern Ocean identified

New factor in the carbon cycle of the Southern Ocean identified
2021-02-09
The term plankton describes usually very small organisms that drift with the currents in the seas and oceans. Despite their small size, they play an important role for our planet due to their immense quantity. Photosynthesizing plankton, known as phytoplankton, for example, produce half of the oxygen in the atmosphere while binding huge amounts of carbon dioxide (CO2). Since the Southern Ocean around Antarctica is very rich in nutrients, phytoplankton can thrive there. It is therefore a key region for controlling atmospheric CO2 concentrations. As other nutrients are abundant, scientists have ...
