BACKGROUND: One method for rejuvenating land polluted with anthropogenic contaminants is through phytoremediation, the reclamation of land through the cultivation of specific crops. The capacity for phytoremediation crops, such as Salix spp., to tolerate and even flourish in contaminated soils relies on a highly complex and predominantly cryptic interacting community of microbial life. METHODS: Here, Illumina HiSeq 2500 sequencing and de novo transcriptome assembly were used to observe gene expression in washed Salix purpurea cv...

Background: To improve the regenerative capacity of aged individuals, we reconstituted bone marrow (BM) of aged mice with young Sca-1 cells, which repopulated cardiac progenitors and prevented cardiac dysfunction after a myocardial infarction (MI). However, the mechanisms involved were incompletely elucidated. This study aimed to investigate whether young, highly regenerative BM Sca-1 cells exert their cardio-protective effects on the aged heart through reactivation of the epithelial-to-mesenchymal transition (EMT) process...

Surgery is commonly used to improve and maintain quality of life. Unfortunately, in vulnerable patients such as the elderly, complications may occur and significantly diminish the outcome. Indeed, after routine orthopedic surgery to repair a fracture, as many as 50% of elderly patients suffer from neurologic complications like delirium. Also, the capacity to heal and regenerate tissue after surgery decreases with age, and can impact the quality of fracture repair and even osseous integration of implants. Thus, a better understanding of mechanisms that drive these age-dependent changes could provide strategic targets to minimize risk for such complications and optimize outcomes...

Determining which facelift procedures yield the most long-term rejuvenating effects and stability over time is an important question in cosmetic surgery: does radical and invasive surgery produce the most long-lasting results? The experience of our team suggests that using a combination of various techniques (liposuction, lipectomy, myotomies, suspensions, tissular induction techniques) appears to be essential to achieve satisfactory, lasting results. In this paper, we describe the lower facelift and neck rejuvenation combined method...

While perovskite solar cells have invigorated the photovoltaic research community due to their excellent power conversion efficiencies (PCEs), these devices notably suffer from poor stability. To address this crucial issue, a solution-processable organic chemical inhibition layer (OCIL) was integrated into perovskite solar cells, resulting in improved device stability and a maximum PCE of 16.3%. Photoenhanced self-doping of the fulleropyrrolidine mixture in the interlayers afforded devices that were advantageously insensitive to OCIL thickness, ranging from 4 to 190 nm...

Adoptive cell therapy using tumor-infiltrating T cells has shown durable responses in patients with melanoma, and immunotherapy using genetically engineered T cells (TCR-T or CAR-T) is rapidly emerging as a promising treatment, especially for hematological malignancies. However, the progress is limited because of the lack of readily available good-quality human T cells. Although the efficacy of adoptive cell therapy correlates with the quality of infusing T cells, most antigen-specific T cells in patients with cancer have been exhausted...

Stem cells have the potential to differentiate into specialized cell types under specific conditions in vivo or in vitro, which are used to cure many diseases related to aging. Somatic cell nuclear transfer (SCNT) can reprogram differential somatic cells into cloned embryos and embryonic stem cells can be derived from these cloned embryos. Recipient oocytes have healthier mitochondria and can improve the metabolism competence, lessen the ROS damage, and rejuvenate mitochondrial function of aged cells during reprogramming...

Background: Inadequate release of retaining ligaments during facelift surgery may lead to an unnatural appearance. However, most facelift surgeons are hesitant in transecting these ligaments to avoid possible injury to facial subbranches. Objectives: In our surgical practice for modified composite flap rhytidectomy we use the finger-assisted malar elevation (FAME) technique in order to enable safe release of the zygomatic cutaneous ligaments through the prezygomatic space under direct vision...

Recent progress in both conceptual and technological approaches to human immunology have rejuvenated a field that has long been dominated by the inbred mouse model. This is a healthy development both for the clinical relevance of immunology and for the fact that it is a way to gain access to the wealth of phenomenology in the many human diseases that involve the immune system. This is where we are likely to discover new immunological mechanisms and principals, especially those involving genetic heterogeneity or environmental influences that are difficult to model effectively in inbred mice...

Animals show a large variability of lifespan, ranging from short-lived as Caenorhabditis elegans to immortal as Hydra. A fascinating case is flatworms, in which reversal of aging by regeneration is proposed, yet conclusive evidence for this rejuvenation-by-regeneration hypothesis is lacking. We tested this hypothesis by inducing regeneration in the sexual free-living flatworm Macrostomum lignano. We studied survival, fertility, morphology, and gene expression as a function of age. Here, we report that after regeneration, genes expressed in the germline are upregulated at all ages, but no signs of rejuvenation are observed...
