Background: The superficial facial fascia comprises the superficial musculoaponeurotic system (SMAS) and the temporoparietal fascia (TPF) and is regarded as a continuous monolayer. However, some evidence indicates that the superficial facial fascia consists of 2 layers in specific areas. Objectives: The authors evaluated the superficial facial fascia for bilayered regions. Methods: Twenty fresh cadavers (40 hemifaces) were dissected to observe the superficial facial fascia...

Exercise improves cognitive function in older adults, but the underlying mechanism is largely unknown. Both lysosomal degradation and mitochondrial quality control decline with age. We hypothesized that exercise ameliorates age-related cognitive decline through the improvement of mitochondrial quality control in aged hippocampus, and this effect is associated with lysosomal proteolysis. Sixteen to eighteen-month old male Sprague Dawley rats underwent swim exercise training for 10 weeks. The exercise regimen prevented cognitive decline in aged rats, reduced oxidative stress, and rejuvenated mitochondria in the aged hippocampus...

BACKGROUND: Facial rejuvenation is an expanding field with an increasing number of treatment modalities. Several non-autologous filler materials are available for soft tissue augmentation. Calcium hydroxylapatite (CaOH) is aimed at increasing collagen neosynthesis and thereby producing long term augmentation effects. Despite a multitude of observational reports, the field is suffering from lack of quantitative morphometic evaluation methods. OBJECTIVE: The objective of this proof-of-principle study was to investigate whether the effects of facial tissue augmentation with CaOH (Radiesse™) can be quantified and followed up using 3D surface scanning...

Cordyceps militaris has been used in traditional Chinese medicine for many years, but its frequent degeneration during continuous maintenance in culture can lead to substantial commercial losses. In this study, a degenerated strain of C. militaris was obtained by subculturing a wild-type strain through 10 successive subcultures. The relative abundance of the 2 mating types seems to be out of balance in the degenerated strain. By cross-mating 4 single-ascospore isolates (2 for MAT 1-1 and 2 for MAT 1-2) from the degenerated strain, we were able to restore fruiting body production to wild-type levels...

In "On growth and form", D'Arcy Wentworth Thompson (1917) stresses the inevitable interactions between physics and developmental biology. With the recent progress in molecular genetics, live imaging, micromechanics and modeling, the study of morphogenesis has been rejuvenated in the present century: the activity of developmental genes can be interpreted in terms of mechanical properties to dissect the chain of events behind shape changes; in turn, patterns of shape- and growth-derived mechanical stress are calculated and shown to act as signals controlling cell effectors, in synergy with biochemical cues, thereby channeling morphogenesis...

Epigenetic variation with age is one of the most important hallmarks of aging. Resetting or repairing the epigenome of aging cells in intact animals may rejuvenate the cells and perhaps the entire organism. In fact, differentiated adult cells, which by definition have undergone some epigenetic changes, are capable of being rejuvenated and reprogrammed to create pluripotent stem cells and viable cloned animals. Apparently, such reprogramming is capable of completely resetting the epigenome. However, attempts to fully reprogram differentiated cells in adult animals have failed in part because reprogramming leads to formation of teratomas...

We aimed to investigate the efficacy and safety of using the 1064-nm Q-switched neodymium-doped yttrium aluminum garnet (Nd:YAG) laser (QSNYL) for skin rejuvenation in patients with Nevus of Ota. A retrospective, randomized, split-faced, clinical study was conducted. Twenty-nine patients with unilateral moderate to severe Nevus of Ota were enrolled. The participants completed 3-13 sessions of QSNYL treatments 3-6 months apart. Two independent physicians compared the treated and untreated sides of the face to evaluate the clearance of Nevus of Ota, the wrinkle severity rating scale (WSRS), the global aesthetic improvement scale (GAIS), and adverse event reporting...

BACKGROUND: Storage of red blood cells (RBCs) under blood bank conditions promotes metabolic modulation within the RBC. This "metabolic storage lesion" may affect the quality and safety of the transfused RBCs. The aim of this study is to determine the metabolic changes in stored RBCs over 42 days of routine storage followed by a US Food and Drug Administration-approved method of rejuvenation, freezing, and preparation for transfusion. STUDY DESIGN AND METHODS: We exploited a mass spectrometry-based metabolomics approach to monitor 42-day-stored citrate phosphate dextrose/AS-1 RBCs (n = 29) that were rejuvenated, glycerolized and frozen, then thawed and deglycerolized, and held for 24 hours at 1 to 6ºC in saline-glucose...

PURPOSE: Human beings encounter radiation in many different situations - from proximity to radioactive waste sites to participation in medical procedures using X-rays etc. Limits for radiation exposures are legally regulated; however, current radiation protection policy does not explicitly acknowledge that biological, cellular and molecular effects of low doses and low dose rates of radiation differ from effects induced by medium and high dose radiation exposures. Recent technical developments in biology and medicine, from single cell techniques to big data computational research, have enabled new approaches for study of biology of low doses of radiation...

The term Kriyakala refers to the recognition of the stage of a disease's progress, which helps to determine appropriate measure to correct the imbalance in Doshas (biological factors). It is a compound expression, comprised of Kriya and Kala, where Kriya means the choice to treatment (medicine, food and daily-routine) used to improve the disturbance in Doshas, and Kala refers to the stage of progress of a disease. Sushruta, an ancient Indian surgeon, has described the concept of Kriyakala in Varnaprashnadhyaya, an ancient Vedic Sanskrit text, which seeks to explain the incidence of Varnas in terms of Doshic disturbances...

In order to produce rejuvenated daughters, dividing budding yeast cells confine aging factors, including protein aggregates, to the aging mother cell. The asymmetric inheritance of these protein deposits is mediated by organelle and cytoskeletal attachment and by cell geometry. Yet it remains unclear how deposit formation is restricted to the aging lineage. Here, we show that selective membrane anchoring and the compartmentalization of the endoplasmic reticulum (ER) membrane confine protein deposit formation to aging cells during division...

BACKGROUND: Dual-taper modular stems have suffered from high revision rates caused by adverse local tissue reactions secondary to fretting and corrosion. We compared the fretting and corrosion behavior of a group of modular neck designs to that of a design that had been recalled for risks associated with fretting and corrosion at the modular neck junction. METHODS: We previously analyzed fretting and corrosion on 60 retrieved Rejuvenate modular neck-stem implants...

Aging is associated with a decline of various body functions, including ability to regenerate. Over recent decades, it has been demonstrated that some of these changes could be reversed in response to factors originating from a young organism, for example, fetal stem cells or "young blood" in models of heterochronic parabiosis. Pregnancy might be considered as parabiotic model of the interaction between two organisms of different age. In this work, we analyzed and summarized data on the effects of pregnancy on the maternal organism that confirm the hypothesis that pregnancy rejuvenates the mother's organism or slows its aging...

There has been an increased recognition for the role volume deflation plays in the aging periorbital area, and as such, rejuvenation strategies to augment and restore volume have developed and evolved. Hyaluronic acid fillers provide an efficient option for volume augmentation with good efficacy, longevity, and safety. An understanding of the changes in the upper and lower periocular area due to aging, the meticulous identification of focal hollows, and the precise delivery of filler to these areas can smooth contours and restore a rejuvenated periorbital area...

Growing evidence supports the view that in adult stem cells, the defining stem cell features of potency and self-renewal are associated with the quiescent state. Thus, uncovering the molecular logic of this reversibly arrested state underlies not only a fundamental understanding of adult tissue dynamics but also hopes for therapeutic regeneration and rejuvenation of damaged or aging tissue. A key question concerns how adult stem cells use quiescence to establish or reinforce the property of self-renewal. Since self-renewal is largely studied by assays that measure proliferation, the concept of self-renewal programs imposed during non-proliferating conditions is counterintuitive...
