Occurrence of microplastics in the environment has become a serious problem with too many variables and unknowns regarding their relationship not only with human health but also with other parts of the environment. The toxic and ecotoxic properties are still a subject of interest and the scientific attitude to their threat is not unified. There are numerous review papers which report on microplastic particles occurrence in water, but similarly complex reviews on methods of their removal are not that frequent. This paper aims to provide a brief overview summarizing the most tested methods of microplastics removal and intends to critically evaluate them accordingly and advert to their discrepancies.

LANGUAGE NOTE | Document text in Chinese; abstract also in English.修煉氣功大有益於人的健康。但對於氣功那些令人震撼的效應,還沒有提出一套比較完整的氣功科學理論來加以解釋。然而,無法用當代已接受的科學理論來說明的現象不應一概斥之為迷信。當我們說“氣功科學”時,我們並不是說氣功已經是一門科學,而是說要以科學的態度、方法、手段和精神來對待氣功,研究氣功,努力開創一個科學探索的新領域。在這一探索中,還要注意從氣功的理論、世界觀和方法論出發來設計氣功科學實驗,而不是以常規科學的方式為萬能的或唯一正確的研究方式。Many people have noticed that practicing qigong is beneficial to human health. However, how does it work is not quite clear. Especially, there is no way to use the contemporarily accepted scientific theories to explain some strikingly impressive effects and phenomena that qigong practitioners have brought out. But we should not take all of them as superstitious simply because they cannot be brought to light by currently accepted scientific theories. Instead, we should seriously explore qigong science.When we speak "qigong science", we do not mean qigong is already a science. Rather, we mean that we ought to study qigong through scientific methods and in scientific attitude and spirit in order to open a new area for scientific inquiry. The basic spirit of science is honesty: truth is truth, and false is false. Science is not static. It is always developing. In scientific investigations of qigong, we must take notice to the special characteristics of qigong: its own theories, worldviews as well as methodologies. In designing scientific experiments on qigong, we should not take currently common scientific designing procedures and rules as absolute and universal standards. Rather, we should adapt them in ways of suiting the peculiar features of qigong practice so that useful information and results can be brought about.DOWNLOAD HISTORY | This article has been downloaded 46 times in Digital Commons before migrating into this platform.

Many studies performed to date have implicated select microbes and dietary factors in a variety of cancers, yet the complexity of both these diseases and the relationship between these factors has limited the ability to translate findings into therapies and preventative guidelines. Here we begin by discussing recently published studies relating to dietary factors, such as vitamins and chemical compounds used as ingredients, and their contribution to cancer development. We further review recent studies, which display evidence of the microbial-diet interaction in the context of cancer. The field continues to advance our understanding of the development of select cancers and how dietary factors are related to the development, prevention, and treatment of these cancers. Finally, we highlight the science available in the discussion of common misconceptions with regards to cancer and diet. We conclude this review with thoughts on where we believe future research should focus in order to provide the greatest impact towards human health and preventative medicine.

Antibiotics are used worldwide to treat diseases in humans and other animals; most of them and their secondary metabolites are discharged into the aquatic environment, posing a serious threat to human health.

Nutrition is important for human health in all stages of life - from conception to old age. Today we know much more about the molecular basis of nutrition. Most importantly, we have learnt that micronutrients, among other factors, interact with genes, and new science is increasingly providing more tools to clarify this interrelation between health and nutrition. Sufficient intake of vitamins is essential to achieve maximum health benefit. It is well established that in developing countries, millions of people still suffer from micronutrient deficiencies. However, it is far less recognized that we face micronutrient insufficiencies also in developed countries.
