βTCP-Poly(3hydroxybutyrate) for Bone Tissue Engineering
Tissue engineering is a technique that involves the in vitro seeding and attachment of cells onto a three-dimensional scaffold. In the case of bone tissue engineering, investigations have been focused mostly on synthetic bioceramic scaffolds based on calcium phosphates, such as hydroxyapatite or tricalcium phosphate. Due to their chemical similarity to an inorganic component of bone, hydroxyapatite, as well as βTCP- and αTCP-based materials, show excellent biocompatibility and osteoconductivity.

Zebrafish: Neurological Diseases
Most neurodegenerative diseases are currently incurable, with large social and economic impacts. Recently, there has been renewed interest in investigating natural products in the modern drug discovery paradigm as novel, bioactive small molecules. Moreover, the discovery of potential therapies for neurological disorders is challenging and involves developing optimized animal models for drug screening. In contemporary biomedicine, the growing need to develop experimental models to obtain a detailed understanding of malady conditions and to portray pioneering treatments has resulted in the application of zebrafish to close the gap between in vitro and in vivo assays. Zebrafish in pharmacogenetics and neuropharmacology are rapidly becoming a widely used organism. Brain function, dysfunction, genetic, and pharmacological modulation considerations are enhanced by both larval and adult zebrafish. Bioassay-guided identification of natural products using zebrafish presents as an attractive strategy for generating new lead compounds. Here, we see evidence that the zebrafish's central nervous system is suitable for modeling human neurological disease and we review and evaluate natural product research using zebrafish as a vertebrate model platform to systematically identify bioactive natural products. Finally, we review recently developed zebrafish models of neurological disorders that have the potential to be applied in this field of research.

Zebrafish Models for Skeletal Muscle Senescence
Aging and sarcopenic changes in skeletal muscles not only reduce locomotor activities in elderly people but also increase the chance of trauma, such as bone fractures, and the incidence of other diseases, such as metabolic syndrome, due to reduced physical activity.

Zebrafish for Diabetes Mellitus with Wound Model
Diabetic foot ulcers cause great suffering and are costly for the healthcare system. Normal wound healing involves hemostasis, inflammation, proliferation, and remodeling. However, the negative factors associated with diabetes, such as bacterial biofilms, persistent inflammation, impaired angiogenesis, inhibited cell proliferation, and pathological scarring, greatly interfere with the smooth progress of the entire healing process. It is this impaired wound healing that leads to diabetic foot ulcers and even amputations. Therefore, drug screening is challenging due to the complexity of damaged healing mechanisms. The establishment of a scientific and reasonable animal experimental model contributes significantly to the in-depth research of diabetic wound pathology, prevention, diagnosis, and treatment. In addition to the low cost and transparency of the embryo (for imaging transgene applications), zebrafish have a discrete wound healing process for the separate study of each stage, resulting in their potential as the ideal model animal for diabetic wound healing in the future.

Xanthine Oxidoreductase Activities
Xanthine oxidoreductase (XOR) is the enzyme that catalyzes the oxidation of hypoxanthine to xanthine and xanthine to uric acid. XOR is widely distributed throughout living organisms and is highly conserved in prokaryotic, plant, and animal species. XOR activity is very versatile, generating both pro-oxidant (primarily within the cell) and anti-oxidant (primarily in plasma) products.

Wrinkle
A wrinkle, also known as a rhytide, is a fold, ridge or crease in the skin or on fabric. Skin wrinkles typically appear as a result of aging processes such as glycation, habitual sleeping positions, loss of body mass, or temporarily, as the result of prolonged immersion in water. Age wrinkling in the skin is promoted by habitual facial expressions, aging, sun damage, smoking, poor hydration, and various other factors.

World Suicide Prevention Day
World Suicide Prevention Day (WSPD) is an awareness day observed on 10 September every year, in order to provide worldwide commitment and action to prevent suicides, with various activities around the world since 2003. The International Association for Suicide Prevention (IASP) collaborates with the World Health Organization (WHO) and the World Federation for Mental Health (WFMH) to host World Suicide Prevention Day. In 2011 an estimated 40 countries held awareness events to mark the occasion. According to WHO's Mental Health Atlas released in 2014, no low-income country reported having a national suicide prevention strategy, while less than 100% of lower-middle income countries, and almost a third of upper-middle and high-income countries had. On its first event in 2003, the 1999 WHO's global suicide prevention initiative is mentioned with regards to the main strategy for its implementation, requiring: As of recent WHO releases, challenges represented by social stigma, the taboo to openly discuss suicide, and low availability of data are still to date obstacles leading to poor data quality for both suicide and suicide attempts: "given the sensitivity of suicide – and the illegality of suicidal behaviour in some countries – it is likely that under-reporting and misclassification are greater problems for suicide than for most other causes of death."

World Index of Moral Freedom
{{Multiple issues| The World Index of Moral Freedom is sponsored and published by the Foundation for the Advancement of Liberty, a libertarian think tank based in Madrid, Spain . The Index is an international index ranking one hundred and sixty countries on their performance on five categories of indicators: The WIMF's first edition was published on 2 April 2016, co-authored by Foundation researchers Andreas Kohl and Juan Pina. A second edition was published by the same foundation in July 2018, this time authored by Juan Pina and Emma Watson.

Work–life Interface
Work–life interface is the intersection of work and personal life. There are many aspects of one's personal life that can intersect with work including family, leisure, and health. Work–life interface is bidirectional; for instance, work can interfere with private life, and private life can interfere with work. This interface can be adverse in nature (e.g., work-life conflict) or can be beneficial (e.g., work-life enrichment) in nature. Recent research has shown that the work–life interface is becoming increasingly boundaryless, especially for technology-enabled workers.
