Protective Mechanism of Adipose-Derived Stem Cells in Remodelling of the Skin Stem Cell Niche During Photoaging.

Cell Physiol Biochem 2018 11;51(5):2456-2471. Epub 2018 Dec 11.

Background/aims: Skin photoaging is primarily caused by the functional attrition of skin stem cells. The skin stem cell niche plays an important role in maintaining stem cell survival and behaviour. In our study, we hypothesized that UVB irradiation induces skin photoaging by changing skin stem cell niches and that transferred adipose-derived stem cells (ADSCs) can remodel the niches by affecting the BMP signalling pathway and transdifferentiating into skin stem cells.

Student Research Committee, Department of Pharmaceutics, Faculty of Pharmacy, Mazandaran University of Medical Sciences, Sari, Iran. Electronic address:

Skin color disorders can be caused by various factors, such as excessive exposure to sunlight, aging and hormonal imbalance during pregnancy, or taking some medications. Kojic acid (KA) is a natural metabolite produced by fungi that has the ability to inhibit tyrosinase activity in synthesis of melanin. The major applications of KA and its derivatives in medicine are based on their biocompatibility, antimicrobial and antiviral, antitumor, antidiabetic, anticancer, anti-speck, anti-parasitic, and pesticidal and insecticidal properties.

The method used to dry washed hands affects the number and type of transient and residential bacteria remaining on the skin.

J Hosp Infect 2018 Dec 8. Epub 2018 Dec 8.

Southampton, UK.

Background: Widespread antibiotic resistance has led to fears that we are entering a pre-antibiotic era and the relatively simple premise of hand washing to reduce transfer of bacteria and viruses has never been more important. Much of the emphasis has been on handwashing technique, type of soap and maintaining compliance but effective drying of the hands is just as important.

Aim: To compare the efficacy of drying washed hands with a jet air dryer or paper towels to remove transient bacterial contamination and to determine the effect on residential flora. Read More

Genes known to escape X chromosome inactivation predict co-morbid chronic musculoskeletal pain and posttraumatic stress symptom development in women following trauma exposure.

Am J Med Genet B Neuropsychiatr Genet 2018 Dec 11. Epub 2018 Dec 11.

Institute for Trauma Recovery, University of North Carolina, Chapel Hill, North Carolina.

Co-morbid chronic musculoskeletal pain (CMSP) and posttraumatic stress symptoms (PTSS) are frequent sequelae of motor vehicle collision, are associated with greater disability than either outcome alone, and are more prevalent in women than men. In the current study we assessed for evidence that gene transcripts originating from the X chromosome contribute to sex differences in vulnerability to CMSP and PTSS after motor vehicle collision. Nested samples were drawn from a longitudinal study of African American individuals, and CMSP (0-10 numeric rating scale) and PTSS (impact of events scale, revised) outcomes were assessed 6 months following motor vehicle collision.

J Dtsch Dermatol Ges 2018 Dec;16(12):1425-1432

Department of Dermatology and Venereology, Innsbruck Medical University, Innsbruck, Austria.

The nomenclature system agreed upon by the Chapel Hill Consensus Conference (CHCC) with respect to the terminology and precise definition of the various types of vasculitis has gained widespread interdisciplinary and international acceptance. As the revised version from 2012 (CHCC 2012) does not address the special features of vasculitis of the skin, it has recently been supplemented with an addendum containing the nomenclature of cutaneous vasculitides (D-CHCC). The present article provides the German translation of the terms and defintions of the D-CHCC as well as additional explanatory comments. Read More

Evolution of Our Understanding of the Hyperparathyroid Syndromes: A Historical Perspective.

J Bone Miner Res 2018 Dec 10. Epub 2018 Dec 10.

Calcium Research Laboratory, Metabolic Disorders and Complications Program, Research Institute of the McGill University Health Centre, Montreal, Canada.

We review advancing and overlapping stages for our understanding of the expressions of six hyperparathyroid (HPT) syndromes: multiple endocrine neoplasia type 1 (MEN1) or type 4, multiple endocrine neoplasia type 2A (MEN2A), hyperparathyroidism-jaw tumor syndrome, familial hypocalciuric hypercalcemia, neonatal severe primary hyperparathyroidism, and familial isolated hyperparathyroidism. During stage 1 (1903 to 1967), the introduction of robust measurement of serum calcium was a milestone that uncovered hypercalcemia as the first sign of dysfunction in many HPT subjects, and inheritability was reported in each syndrome. The earliest reports of HPT syndromes were biased toward severe or striking manifestations. Read More

Humans constantly lose epithelial cells, and these biological traces are frequently studied in the context of criminal investigations. The objective of this work was to examine the genetic profile in samples of forensic interest (nail and skin epithelial cells) of bone marrow transplant patients and discuss its forensic and clinical implications. The genetic profile of nail, epidermal cells and blood samples of patients receiving HSCT was analyzed by the amplification and sequencing of 38 insertion/deletion polymorphisms and 15 short tandem repeat polymorphisms.

A phase II trial of the effect of perindopril on hand-foot skin reaction (HFSR) incidence and severity in patients receiving regorafenib for refractory mCRC.

Cancer Chemother Pharmacol 2018 Dec 8. Epub 2018 Dec 8.

BC Cancer Vancouver Centre, 600-10th Ave W, Vancouver, BC, V5Z 4E6, Canada.

Purpose: Regorafenib is an oral multi-kinase inhibitor that offers an OS benefit to patients with mCRC refractory to standard therapy (Grothey et al., in Lancet 381:303-312, 2013), but comes with potential significant toxicities including grade 3 hand-foot skin reaction (HFSR). The pathogenesis of regorafenib-induced HFSR is not well established, but may be related to alterations in the capillary endothelium. Read More

Multifaceted activities of DNA polymerase η: beyond translesion DNA synthesis.

Curr Genet 2018 Dec 8. Epub 2018 Dec 8.

Laboratory of Genomic Instability and Diseases, Department of Infectious Disease Biology, Institute of Life Sciences, Bhubaneswar, 751023, India.

DNA polymerases are evolved to extend the 3'-OH of a growing primer annealed to a template DNA substrate. Since replicative DNA polymerases have a limited role while replicating structurally distorted template, translesion DNA polymerases mostly from Y-family come to the rescue of stalled replication fork and maintain genome stability. DNA polymerase eta is one such specialized enzyme whose function is directly associated with casual development of certain skin cancers and chemo-resistance. Read More

Side effects of frequently used oral antidiabetics on wound healing in vitro.

Naunyn Schmiedebergs Arch Pharmacol 2018 Dec 7. Epub 2018 Dec 7.

Institute of Translational Wound Research, Centre for Biomedical Education and Research (ZBAF), Witten/Herdecke University, Stockumer Street 10, 58453, Witten, Germany.

Lifestyle diseases such as diabetes and arteriosclerosis are rising in the increasingly aging society, and the number of patients with daily intake of glucose-lowering medication has also increased. Interestingly, knowledge about oral antidiabetics with regard to wound healing is scarce. Therefore, the aim of this study was to identify possible (side) effects of the most frequently prescribed oral antidiabetics on skin cells and wound healing. Read More
