The economical use of water-repellent coatings on polymeric materials in commercial and industrial applications is limited by their mechanical wear robustness and long-term durability. In this study, we demonstrate that polyethylene terephthalate (PET) fabric modified with inorganic,
BACKGROUND
With the increasing use of nail paints, nail art, acetone, repeated manicures, cosmetic nail procedures and detergents, the nail plate undergoes regular damage resulting in rough, lusterless and pigmented nails. Besides that onychomycosis, nail lichen planus, nail pitting and ridging due
We study the low-velocity (0.1-100 microm s(-1)) frictional properties of interfaces between a rough glassy polymer and smooth silanized glass, a configuration which gives direct access to the rheology of the adhesive joints in which shear localizes. We show that these joints exhibit the full
BACKGROUND
Hydrolifting is a newly developed modality of skin rejuvenation, which enhances overall facial volume augmentation and recovers skin thickness through multi-pass HA injection. Although it is commonly performed, only a few articles have reported on the rejuvenating effects of hydrolifting.
BACKGROUND
Photorejuvenation involves the use of lasers or light sources to reverse signs of photoaging. Multiple devices have been shown to be effective over the short-term.
OBJECTIVE
To investigate the long-term clinical results on the face, neck and chest at 4 years using filtered flashlamp
BACKGROUND
Photodamaged skin is characterized not only by rhytides, but also by epidermal and dermal atrophy, rough skin texture, irregular pigmentation, telangiectasias, laxity, and enlarged pores. There is growing interest in the development of noninvasive methods to treat photodamaged skin. Skin
One of the biggest scandals of the recent history of medicine is the conflict of views between the gerontological establishment and the American Academy of Anti-Aging Medicine (A4M). The style used in that discussion was really rough and unusual. On the one hand, according to some representatives of
Background: Oxygenation of the skin has been shown to improve cell growth and cell biosynthesis, which can subsequently improve the skin's appearance.1,2 However, the majority of skin oxygenation techniques are invasive.3,4 A noninvasive skin oxygenation treatment, also known as a carboxytherapy
Biogerontologists and demographers have argued that the fastest, most cost-effective strategies for prevention of the medical problems that afflict those older than 60 years are likely to emerge from a deeper understanding of what factors time the aging process and how aging leads, in rough
Skin aging is a combination of natural aging with superimposed photoaging. Naturally aged skin is thin, fragile and finely wrinkled whereas photoaged skin is rough and thickened with deep coarse wrinkles. In addition photoaging is characterized by mottled pigmentation, solar lentigines,
Repetitive and cumulative distress (acute and/or chronic, psychic and/or biologic) and aging processes (impairment phenomena, agglomerated, and accumulated with the passing of life and senescence periods), as well as distress <==> aging reciprocal amplification-accelerating-aggravation relationships
Cartilaginous cells of aged newts (Triturus cristatus) were studied during hind limb regeneration. The electron microscope was used to study the structure and distribution of chromatin in the cell nuclei, while the DNA content of the chromatin was measured by means of a scanning
In holometabolous insects the fall to zero of the titer of Juvenile Hormone ends its still poorly understood "status quo" mode of action in larvae. Concurrently it initiates metamorphosis of which the programmed cell death of all internal tissues that actively secrete proteins, such as the fat body,
Sphere formation can be used to prepare stem cells (SCs) prior to transplantation. Here SCs isolated from human subepicardial adipose tissue were analyzed at different stages of the monolayer-spheres-monolayer cycle by transmission electron microscopy. The results obtained with both adherent-induced
OBJECTIVE
Our previous histological studies indicated that near-infrared (NIR) irradiation stimulates collagen proliferation in rat and human skin for 3 months. High collagen density in the dermis and smoothing of the epidermis were observed in irradiated rat skin, and appeared to last up to 6
