The identification of conserved genes and pathways that regulate lifespan but also healthspan has resulted in an improved understanding of the link between nutrients, signal transduction proteins, and aging but has also provided evidence for the existence of multiple "longevity programs," which are selected based on the availability of nutrients. Periodic fasting and other dietary restrictions can promote entry into a long-lasting longevity program characterized by cellular protection and optimal function but can also activate regenerative processes that lead to rejuvenation, which are independent of the aging rate preceding the restricted period...

Micro-damages always occur and accumulate in asphalt pavement materials under the effects of temperature, vehicle loads and other factors during service. Accordingly, self-healing microcapsules could be added into asphalt binder and repair micro-damages to prevent damage extension in time. In this study, the emulsified rejuvenator and melamine-urea-formaldehyde resin (MUF) were selected as the core and cyst wall materials, respectively, and in-situ polymerization method was applied to synthesize the novel microcapsules...

Hyaluronic acid injection is 1 of the most popular procedures in facial rejuvenation and augmentation. It is widely popular in the cosmetic surgery due to several advantages, which include rapid effect, minimal injury, and a short postoperative recovery period. With continuous increase in hyaluronic acid injections, many cases of hyaluronic acid injection-induced embolism have been reported. At present, methods for early treatment of hyaluronic acid injection-induced embolism include local injection of hyaluronidase, topical application of nitroglycerin ointment, massage, hot compression, and intravenous injections of antibiotics and hormones...

Melt-spun metallic Al86 Ni₉La₅ glassy ribbons solidified at different circumferential speeds ( S c ) were subjected to high-energy ball milling at room and cryogenic temperatures. Crystallization induced by milling was found in the Al86 Ni₉La₅ solidified at lower circumferential speed ( S c = 14.7 m/s), while the Al86 Ni₉La₅ with S c = 36.6 m/s kept amorphous. Besides, a trend of structural rejuvenation during milling process was observed, as the onset temperatures ( T x1 , T x2 ) and the crystallization enthalpies (Δ H ₁, Δ H ₂) first decreased and then increased along with the milling time...

Hyaluronic acid (HA) is a high molecular weight, non-sulfated anionic polysaccharide from glycosamine glycan family. It is a versatile biomaterial that binds to specific cell receptor CD44 (frequently over-expressed on the tumor cell surface) and is useful in skin rejuvenation, drug delivery, tissue engineering and molecular imaging due to its biodegradable, non-toxic, biocompatible, non-immunogenic and non-inflammatory characteristics. It can be chemically modified by cross-linking, grafting, linking with hydrophobic substances and drugs, or through polyion complex formation with oppositely charged polysaccharides, proteins or surfactants...

Aphasia is considered as an acquired neurological disorder of communication, which is characterised by the symptoms on all levels of language dysfunction. The current study was planned to explore the outcomes of script training in a patient with Broca's aphasia through quantitative approach using a single-subject-multiple-baseline research design across behaviours. The probes were obtained during the baseline, treatment, maintenance and generalisation phases for tracking the spoken use of scripted content. All the probes were transcribed verbatim and no value of Cohen's Kappa Coefficient (K) was below 0...

Sound knowledge of the rheology of hyaluronic acids is fundamental for facial rejuvenation procedures. Hyaluronic acid implants are subjected to complex mechanical forces within the facial tissues that vary depending on the anatomical region. Analysis of these forces is important to establish the rheological specifications of hyaluronic acid implants in each specific zone. This approach will optimize the correction of age-related loss of volume, since the filler will be chosen as a function of the mechanics of the anatomical zone, with the objective to respect facial dynamics...

Human induced Pluripotent Stem Cell (hiPSC)-derived models have advanced the study of neurodegenerative diseases, including Parkinson's (PD). While age is the strongest risk factor for these disorders, hiPSC-derived models represent rejuvenated neurons. We developed hiPSC-derived Aged dopaminergic and cholinergic neurons to model PD and related synucleinopathies. Our new method induces aging through a 'semi-natural' process, by passaging multiple times at the Neural Precursor Cell stage, prior to final differentiation...

BACKGROUND: Correction of tear trough (TT) deformity is a crucial aspect of facial rejuvenation. Because the anatomical origins of TT deformity lie in the TT ligaments, which firmly attach the dermis to the periosteum, the release of TT ligaments should be considered when performing an etiological correction. The aim of this paper is to propose an alternative method for TT deformity correction, comprising use of filler together with the release of TT ligaments. This technique was compared to the procedure of only percutaneous filler...

The periorbital region is a focal point on the face. Dermatochalasis, fat herniation, blepharoptosis, brow ptosis, deep tear troughs, and malar fat pad descent are all age-related changes that occur around the eyes, and successful rejuvenation involves addressing all of these changes. Restoring a youthful, vibrant appearance to the eyes and periorbital areas can often only be accomplished with a combination of surgical and nonsurgical interventions. Facial plastic surgeons should have a comprehensive knowledge of all of these options and their applications to ensure good patient outcomes and satisfaction...

Rejuvenation of the lower face and neck strives to reverse signs of aging while optimizing the patient's natural anatomy. Common features of an aesthetically pleasing lower face include a well-defined and appropriately balanced mandible and an acute cervicomental angle. Correction of the aging lower face and neck is accomplished through multiple surgical interventions, performed either alone or in combination. Determination of appropriate procedures is based on individual anatomic pathology. Intimate knowledge of facial anatomy and the complexity of the aging process is paramount to achieve a natural and aesthetic result...

In the last several years, there has been an increasing demand for surgical facial feminization or masculinization to treat the gender dysphoric patient. However, while aesthetic ideals for facial rejuvenation are well described and taught, there is a relative paucity of literature on how to achieve a feminine or masculine morphology. It is thus becoming increasingly important for facial plastic surgeons to understand patient goals regarding facial feminization or masculinization, and to have a systematic approach for analyzing the female and male face...
