Bamboo vinegar is a concentrated liquid obtained from bamboo under high temperature and anaerobic conditions. It contains more than 200 organic components, including organic acids, phenols, ketones, alcohols, and esters, among which acetic acid is the main component. Although bamboo vinegar has been approved by the China Food and Drug Administration as a cosmetic raw material, commercially available bamboo vinegar often contains impurities whose efficacy is not clear, and phenolic compounds and aromatic hydrocarbons in it may be harmful to humans.

Nevertheless, bamboo vinegar has anti-acne potential, especially against the inhibitory effect of Propionibacterium acnes, the key microorganism in the pathogenesis of acne. While antibiotics are commonly used to treat acne, the concerns for drug resistance have limited their use.

In a study published in the Volume 1, Issue 2 in Journal of Dermatologic Science and Cosmetic Technology, a team of researchers from Central South University of Forestry and Technology in China explored the mechanism of the controlled-release system of bamboo vinegar and its application potential of in cosmetics.

“Bamboo vinegar was refined through reduced-pressure distillation, which increased the content of organic acids, reduced tar content and enhanced the active ingredients while minimizing harmful components,” explains corresponding author Sheng Zhang. “We used activated bamboo charcoal to adsorb the bamboo vinegar, allowing for a gradual release over a period exceeding two hours, effectively demonstrating a slow-release effect.”

The findings auggest that refined bamboo vinegar could be a promising raw material for anti-acne cosmetic formulations. The release rate of the bamboo charcoal/bamboo vinegar complex in water reached 70.57% within 15 minutes and then slowed to a plateau. This slow-release behavior aligns with the Ritger-Peppas model, which is advantageous for reducing skin irritation and extending the bacteriostatic duration.

“The findings present a novel concept for anti-acne cosmetics and lay the groundwork for further research into the use of bamboo vinegar slow-release systems with bamboo charcoal as a carrier,” adds Zhang. “Future studies should explore additional cosmetic benefits of bamboo vinegar, such as dandruff removal, anti-wrinkle effects and more.”

When is the best time of day for cancer treatment?

When is the best time of day for cancer treatment?
2024-08-23
How effective medications are depends on various factors, including the time of day when they are administered. Why? Because our bodies don’t always function exactly the same. Instead, they follow the cycle set by their internal clock, otherwise known as circadian rhythm. But since each person’s circadian rhythm is different and depends on a number of different factors, it is difficult to tailor medication schedules to an individual patient’s body clock. Researchers at Charité – Universitätsmedizin Berlin have now developed a method for determining the optimum time of cancer treatment based on certain breast cancer ...

Rates of obesity-related cancer are rising sharply in young Chinese people

2024-08-23
Obesity-related cancer rates in China were rising at an alarming 3.6% every year between 2007 and 2021 while non-obesity-related cancers remained stable, according to the first comprehensive study published August 22 in the Cell Press journal Med. The increase is particularly pronounced among young people, highlighting the urgent need for better public health policies to address China’s growing overweight and obesity rates. “If we don’t drastically change the obesity epidemic, the rates of cancer associated with obesity will inevitably continue to rise,” says Jin-Kui Yang, the paper’s corresponding author and an endocrinologist ...

Neighborhood-level disparities in hypertension prevalence and treatment among middle-aged adults

2024-08-23
About The Study: Researchers found corresponding increases in hypertension prevalence as neighborhood disadvantage and the percentage of Black patients residing in a neighborhood increased in this cross-sectional study. A higher burden of midlife hypertension was identified in Black adults compared with other racial and ethnic groups that persisted across levels of socioeconomic disadvantage. This study also found that living in socioeconomically disadvantaged neighborhoods was associated with higher hypertension ...

Strength training activates cellular waste disposal

Strength training activates cellular waste disposal
2024-08-23
The elimination of damaged cell components is essential for the maintenance of the body’s tissues and organs. An international research team led by the University of Bonn has made significant findings on mechanisms for the clearing of cellular wastes, showing that strength training activates such mechanisms. The findings could form the basis for new therapies for heart failure and nerve diseases, and even afford benefits for manned space missions. A corresponding article has been published in the latest issue of the journal Current Biology. EMBARGOED: Do not publish until 5 pm CEST ...

Water activation induced strong interfacial hydrogen bonding interactions for efficient oxygen reduction reaction

Water activation induced strong interfacial hydrogen bonding interactions for efficient oxygen reduction reaction
2024-08-23
Exploring new energy storage and conversion technologies is crucial for sustainable human development. Proton exchange membrane fuel cells (PEMFCs) and metal-air batteries are particularly promising due to their high energy efficiency and environmental friendliness. A key component in these technologies is the oxygen reduction reaction (ORR) catalyst. Traditionally, ORR catalysts rely on expensive platinum group metals (PGM), which are cost-prohibitive for widespread use. This has spurred interest in developing non-precious metal alternatives, such as transition metal/nitrogen-doped carbon-based materials (M–N–C). Among these, Fe–N–C ...

Single nucleosomes tracked in live cells during cell division using super-resolution microscopy

Single nucleosomes tracked in live cells during cell division using super-resolution microscopy
2024-08-23
Individual cells divide through a process called mitosis, during which the cell’s copied DNA is separated between two resulting daughter cells. Despite recent advances in cell biology, the mechanism by which DNA condenses during mitosis is still poorly understood. Researchers recently tracked small stretches of DNA wound around histone proteins, called nucleosomes, to better characterize nucleosome behavior during cell division. DNA is organized as chromatin, which are dynamic structures comprised of DNA, RNA, and proteins that regulate the accessibility of genes for expression and the overall configuration of genetic material in the cell. Histone proteins, for example, are positively ...

Slow down in China’s methane emission growth

Slow down in China’s methane emission growth
2024-08-23
Methane is a potent greenhouse gas. Since the Industrial Revolution, atmospheric methane concentrations have nearly doubled, with its radiative forcing accounting for one-third of all greenhouse gases. As one of the world's largest methane emitters, China made a clear commitment as early as 2007 to "strive to control the growth rate of methane emissions." The country's 12th, 13th, and 14th Five-Year Plans all proposed measures to control methane emissions. In 2023, China released the "Methane Emission Control Action ...

Socioeconomics shape children’s connection to nature more than where they live

2024-08-23
The income and education levels of a child’s environment determine their relationship to nature, not whether they live in a city or the countryside. This is the finding of a new study conducted by researchers at Lund University, Sweden. The results run counter to the assumption that growing up in the countryside automatically increases our connection to nature, and yet the study also shows that nature close to home increases children’s well-being. There is a general concern that, with urbanisation, people have lost contact with nature. According to research, less contact ...

The higher the environmental stress, the lower the resistance to global change

The higher the environmental stress, the lower the resistance to global change
2024-08-23
An international study led by Institute of Natural Resources and Agrobiology of Seville (IRNAS-CSIC), of the Spanish National Research Council (CISC), has shown that as the number of global change factors increases, terrestrial ecosystems become more sensitive to the impacts of global change. The results, published in the prestigious journal Nature Geoscience, show that the resistance of our ecosystems to global change decreases significantly as the number of environmental stressors increases, especially when this stress is sustained over time. This is the conclusion reached by the Biodiversity and Ecosystem Functioning ...
