NanoBubble-Mediated Oxygenation for Hypoxic Pathologies
Nanobubbles also known as ultra-fine bubbles or sub-micron bubbles, are extremely small gas-filled spherical bodies enclosed by an interface (gas–liquid or gas–solid) with a diameter of less than 1000 nm (i.e., ranging in size from tens to hundreds of nanometers in diameter). In other words, nanobubbles are composed of gas, such as oxygen or nitrogen, encapsulated within a liquid, typically water, and stabilized by a thin layer of molecules at the gas–liquid interface.

Bugang
Bugang is a Daoist ritual dance or walk, based upon the limping Yubu "Steps of Yu" tradition, in which a Taoist priest paces through a supernatural pattern, such as stars in the Big Dipper or numbers in the Loshu magic square. Texts from the (4th century) Shangqing School "revelations" contain the earliest descriptions of bugang, frequently with the practitioner pacing among constellations, especially the Big Dipper's stars. When religious Daoism began during the Six Dynasties period (220–589 CE), the expression bugang tadou 步罡踏斗 "pacing the guideline and treading on (the stars of) the Dipper" became popular.

Bacterial Vaginosis
Bacterial vaginosis (BV) has been reported in one-third of women worldwide at different life stages, due to the complex balance in the ecology of the vaginal microbiota. It is a common cause of abnormal vaginal discharge and is associated with other health issues. Since the first description of anaerobic microbes associated with BV like Gardnerella vaginalis in the 1950s, researchers have stepped up the game by incorporating advanced molecular tools to monitor and evaluate the extent of dysbiosis within the vaginal microbiome, particularly on how specific microbial population changes compared to a healthy state. Moreover, treatment failure and BV recurrence rate remain high despite the standard antibiotic treatment. Consequently, researchers have been probing into alternative or adjunct treatments, including probiotics or even vaginal microbiota transplants, to ensure successful treatment outcomes and reduce the colonization by pathogenic microbes of the female reproductive tract.

Human Gut Mycobiome in IBD
The human microbiota is a diverse microbial ecosystem associated with many beneficial physiological functions, as well as numerous disease etiologies. Dominated by bacteria, the microbiota also includes commensal populations of fungi, viruses, archaea, and protists. Unlike bacterial microbiota, which was extensively studied in the past two decades, these non-bacterial microorganisms, their functional roles, and their interaction with one another or with host immune system have not been as widely explored. This review covers the recent findings on the fungal communities of the human gastrointestinal microbiota, termed the “mycobiome”, and their involvement in health and disease, with particular focus on the pathophysiology of inflammatory bowel disease.

Assessment Scale of Competitiveness of Wellness Destinations in Thailand
An assessment scale was developed to measure the competitiveness of wellness destinations in Thailand, particularly from the perspective of the wellness tourism firm. Several studies emphasized exploring the management of tourist attractions, the development of routes, and the promotion of products to wellness tourists. A number of studies concerning Thai spas and developing community wellness tourism explored quality development for businesses and communities and the types of wellness tourism in a particular area. However, there has been a lack of research regarding the development of a measurement scale for evaluating the competitiveness of wellness destinations, particularly among those that offer niche services, rather than a more general view; this would be especially useful for Thai destinations.

Configuration Determinations of Flexible Marine Natural Products
Flexible marine natural products (MNPs), such as eribulin and bryostatin, play an important role in the development of modern marine drugs. However, due to the multiple chiral centers and geometrical uncertainty of flexible systems, configuration determinations of flexible MNPs face great challenges, which, in turn, have led to obstacles in druggability research. To resolve this issue, the comprehensive use of multiple methods is necessary.

Arms Export Control Act
The Arms Export Control Act of 1976 (Title II of Pub.L. 94–329, 90 Stat. 729, enacted June 30, 1976, codified at 22 U.S.C. ch. 39) gives the President of the United States the authority to control the import and export of defense articles and defense services. The H.R. 13680 legislation was passed by the 94th Congressional session and enacted into law by the 38th President of the United States Gerald R. Ford on June 30, 1976. The Act of Congress requires international governments receiving weapons from the United States to use the armaments for legitimate self-defense. Consideration is given as to whether the exports "would contribute to an arms race, aid in the development of weapons of mass destruction, support international terrorism, increase the possibility of outbreak or escalation of conflict, or prejudice the development of bilateral or multilateral arms control or nonproliferation agreements or other arrangements." The Act also places certain restrictions on American arms traders and manufacturers, prohibiting them from the sale of certain sensitive technologies to certain parties and requiring thorough documentation of such trades to trusted parties. When the President is aware of the possibility of violations of the AECA, the law requires a report to Congress on the potential violations. U.S. Immigration and Customs Enforcement (ICE) conducts an industry outreach program called the Project Shield America to prevent foreign adversaries, terrorists, and criminal networks from obtaining U.S. munitions and strategic technology.

Biological Carbon Fixation
Biological carbon fixation or сarbon assimilation is the process by which inorganic carbon (particularly in the form of carbon dioxide) is converted to organic compounds by living organisms. The compounds are then used to store energy and as structure for other biomolecules. Carbon is primarily fixed through photosynthesis, but some organisms use a process called chemosynthesis in the absence of sunlight. Organisms that grow by fixing carbon are called autotrophs, which include photoautotrophs (which use sunlight), and lithoautotrophs (which use inorganic oxidation). Heterotrophs are not themselves capable of carbon fixation but are able to grow by consuming the carbon fixed by autotrophs or other heterotrophs. "Fixed carbon", "reduced carbon", and "organic carbon" may all be used interchangeably to refer to various organic compounds. Chemosynthesis is carbon fixation driven by chemical energy, rather than from sunlight. Sulfur- and hydrogen-oxidizing bacteria often use the Calvin cycle or the reductive citric acid cycle.

Plant Produced Biopharmaceuticals against SARS-CoV-2
SARS-CoV-2 is an enveloped RNA virus with a single-stranded, positive-sense genome of ~29.9 kB in size. The virus consists of four major structural proteins, named spike (S), nucleocapsid (N), envelope (E), and membrane proteins (M). The S protein which is present as a crown-like spike on the outer surface of the virus plays a major role in viral entry into mammalian cells. Specifically, the virus uses the receptor binding domain (RBD) on the S protein to interact with human angiotensin-converting enzyme 2 (ACE2) receptor as a critical initial step to enter target cells. Plants have provided a promising production platform for both bioactive chemical compounds (small molecules) and recombinant therapeutics (big molecules). Plants naturally produce a diverse range of bioactive compounds as secondary metabolites, such as alkaloids, terpenoids/terpenes and polyphenols, which are a rich source of countless antiviral compounds. Plants can also be genetically engineered to produce valuable recombinant therapeutics. This molecular farming in plants has an unprecedented opportunity for developing vaccines, antibodies, and other biologics for pandemic diseases because of its potential advantages, such as low cost, safety, and high production volume.

Cinnamon
Cinnamon is a free and open-source desktop environment for the X Window System that derives from GNOME 3 but follows traditional desktop metaphor conventions. Cinnamon is the principal desktop environment of the Linux Mint distribution but is available as an optional desktop for other Linux distributions and other Unix-like operating systems as well. The development of Cinnamon began as a reaction to the April 2011 release of GNOME 3 in which the conventional desktop metaphor of GNOME 2 was abandoned in favor of GNOME Shell. Following several attempts to extend GNOME 3 such that it would suit the Linux Mint design goals, the Mint developers forked several GNOME 3 components to build an independent desktop environment. Separation from GNOME was completed in Cinnamon 2.0, which was released in October 2013. Applets and desklets are no longer compatible with GNOME 3. As the distinguishing factor of Linux Mint, Cinnamon has generally received favorable coverage by the press, in particular for its ease-of-use and gentle learning curve. With respect to its conservative design model, Cinnamon is similar to the XFCE and GNOME 2 (MATE and GNOME Flashback/Classic) desktop environments.

Attachment and Health
Attachment and Health is psychological model which considers how attachment theory pertains to people’s preferences and expectations for the proximity of others when faced with stress, threat, danger or pain. In 1982 the American Psychiatrist, Lawrence Kolb, noticed that patients with chronic pain displayed behaviours with their healthcare providers akin to what children might display with an attachment figure, thus marking one of the first applications of attachment theory to physical health. Development of adult attachment theory and adult attachment measures in the 1990s provided researchers with the means to apply attachment theory to health in a more systematic way. Since that time it has been used to understand variation in stress response, health outcomes and health behaviour. Ultimately, the application of attachment theory to health care may enable health care practitioners to provide more personalized medicine by creating a deeper understanding of patient distress and allowing clinicians to better meet their needs and expectations.

Earnings before Interest, Taxes, Depreciation, and Amortization
A company's earnings before interest, taxes, depreciation, and amortization (commonly abbreviated EBITDA, pronounced /iːbɪtˈdɑː/, /əˈbɪtdɑː/, or /ˈɛbɪtdɑː/) is an accounting measure calculated using a company's earnings, before interest expenses, taxes, depreciation, and amortization are subtracted, as a proxy for a company's current operating profitability (i.e., how much profit it makes with its present assets and its operations on the products it produces and sells, as well as providing a proxy for cash flow). Though often shown on an income statement, it is not considered part of the Generally Accepted Accounting Principles (GAAP) by the SEC.
