Artificially structured materials with unit cells at sub-wavelength scale, known as metamaterials, have been widely used to precisely control and manipulate waves thanks to their unconventional properties which cannot be found in nature. In fact, the field of acoustic metamaterials has been much developed over the past 15 years and still keeps developing. Here, we present a topical review of me...

Micro/sub-micron emulsion and related systems have received a lot of attention in the last years for their common use as vehicles for topical administration. These systems can be defined as fine emulsion dispersion with droplet sizes in the sub-micron range, and consisted of an aqueous phase, oily phase, and surfactants that are necessary for stabilizing the interface and forming the drops [1]....

UNLABELLED This study observed the quantity and functions of wound neu- trophils after topical insulin treatment and investigated the effect of insulin on the wound inflammatory response, as well as the mechanism of insulin-induced wound healing. METHODS Full-thickness excisional wounds were made on the dorsal symmetrical site of C57BL/6J mice. The wounds were treated with either 0.03U insuli...

Botswana exhibits a medium fertility rate (i.e.4.0-5.0 births per woman). One of the three countries in sub-Sahara Africa (Kenya and Zimbabwe are the other two) reported to be experiencing incipient fertility decline, an indication of the subcontinent's entry into the second phase of the fertility transition after undergoing significant changes in the proximate determinants of fertility over th...

Because of the flexibility and complexity of Newly Emerging Science and Technologies (NESTs), traditional statistical analysis fails to capture technology evolution in detail. Generating competitive technical intelligence supports industrial, governmental, and academic decisions to guide future development trends. Patents are one of the most important NESTs data sources and are pertinent to dev...

Excessive exposure to ultraviolet (UV) and high-energy visible (HEV) light can cause sunburns, wrinkles, even skin cancer. Therefore, the development of effective UV–HEV-shielding agents is great importance human health. In this study, semiconducting graphitic carbon nitride (g-C3N4) incorporated into interlayer space mica through intercalation cyanamide subsequent pyrolysis reactions form a se...

Herbal medicines have been used in preventing and treating skin disorders for centuries. It has been demonstrated that systemic administration of chrysanthemum extract exhibits anti-inflammatory properties. However, whether topical applications of apigenin, a constituent of chrysanthemum extract, influence cutaneous inflammation is still unclear. In the present study, we first tested whether to...

Although topical glucocorticoids (GCs) show potent anti-inflammatory activity in inflamed skin, they can also exert numerous harmful effects on epidermal structure and function. In contrast, topical applications of ligands of peroxisome proliferator-activated receptor-α (PPARα) not only reduce inflammation but also improve cutaneous barrier homeostasis. Therefore, we examined whether sequential...
