We evaluated a new handheld stereoscopic imaging system capable of visualizing scars with digital three-dimensional (3D) models and providing automated morphometric estimates. The objective was to validate the repeatability and accuracy of intra- and inter-investigator scan results.

Engineered metal plates with depressed and elevated model scars (n = 72) were scanned six times by one investigator. In vivo hypertrophic and atrophic scars (n = 15) were scanned once by three investigators. The repeatability of morphometric estimates was assessed using coefficients of variation (CVs) to compare the variation among multiple scan results for both models and in vivo scars, with 0% reflecting a perfect match. Scar estimates from digital 3D reconstructions were compared with the known dimensions of physical model scars and with ruler measurements of in vivo scars.

A total of 48 model scars and 12 in vivo scars were eligible for automated analyses with the imaging system's proprietary software. Intra-investigatorssessment variation. The best results are achieved by minimizing subject movement. Lasers Surg.

This motif, which is also popular in synthetically designed proteins and peptides, is known for its stability and adaptability to broad functions. Here, we systematically probe all 49,000 unique beta hairpin substructures contained within the Protein Data Bank (PDB) to uncover key characteristics correlated with stable beta hairpin structure, including amino acid biases and enriched interstrand contacts. We find that position specific amino acid preferences, while seen throughout the beta hairpin structure, are most evident within the turn region, where they depend on subtle turn dynamics associated with turn length and secondary structure. We also establish a set of broad design principles, such as the inclusion of aspartic acid residues at a specific position and the careful consideration of desired secondary structure when selecting residues for the turn region, that can be applied to the generation of libraries encoding proteins or peptides containing beta hairpin structures.Slippery slope-, taboo-breaking- or Nazi-analogy-arguments are common, but not uncontroversial examples of the complex relationship between bioethics and the various ways of using historical arguments in these debates. In our analysis we examine first the relationship between bioethics and medical history both as separate disciplines and as argumentative practices. Secondly, we then analyse six common types of historical arguments in bioethics (slippery slope-, analogy-, continuity-, knockout/taboo-, ethical progress- and accomplice-arguments), some as arguments within the academic debate of bioethics, others as arguments within political and public debates over bioethical issues. We conclude by suggesting to bioethicists to better understand historical arguments as socially and culturally embedded practices of critical reflection of power, medical and government paternalism and possible future scenarios. More interdisciplinarity between ethicists and medical historians is needed to appropriately rationalize and understand the different legacies.
Congenital facial weakness (CFW) can result from facial nerve paresis with or without other cranial nerve and systemic involvement, or generalized neuropathic and myopathic disorders. Moebius syndrome is one type of CFW. In this study we explored the utility of electrodiagnostic studies (EDx) in the evaluation of individuals with CFW.

Forty-three subjects enrolled prospectively into a dedicated clinical protocol and had EDx evaluations, including blink reflex and facial and peripheral nerve conduction studies, with optional needle electromyography.

MBS and hereditary congenital facial paresis (HCFP) subjects had low-amplitude cranial nerve 7 responses without other neuropathic or myopathic findings. Carriers of specific pathogenic variants in TUBB3 had, in addition, a generalized sensorimotor axonal polyneuropathy with demyelinating features. Myopathic findings were detected in individuals with Carey-Fineman-Ziter syndrome, myotonic dystrophy, other undefined myopathies, or CFW with arthrogryposis, ophthalmoplegia, and other system involvement.

EDx in CFW subjects can assist in characterizing the underlying pathogenesis, as well as guide diagnosis and genetic counseling.

In this open-label nonrandomized clinical trial, efficacy of nano-curcumin oral formulation has been evaluated in hospitalized patients with mild-moderate COVID-19. Forty-one patients who fulfilled the inclusion criteria were allocated to nano-curcumin (n = 21) group (Sinacurcumin soft gel, contains 40 mg curcuminoids as nanomicelles, two capsules twice a day) or control (n = 20) group, for 2 weeks. Patients' symptoms and laboratory data were assessed at baseline and during follow-up period. Most of symptoms including fever and chills, tachypnea, myalgia, and cough resolved significantly faster in curcumin group. Moreover, SaO2 was significantly higher in treatment group after 2, 4, 7, and 14 days of follow-up and lymphocyte count after 7 and 14 days. Duration of supplemental O2 use and hospitalization was also meaningfully shorter in treatment group. It is also noteworthy to mention that no patient in treatment group experienced deterioration of infection during follow-up period, but it occurred in 40% of control group. Bromoenollactone Oral curcumin nano-formulation can significantly improve recovery time in hospitalized COVID-19 patients. Further randomized placebo controlled trials with larger sample size are recommended.Human adipose-derived stromal/stem cells (ASC) have immunomodulatory properties and the potential to differentiate into several cell lines, important for application in regenerative medicine. However, the contamination with dermal fibroblasts (FIB) can impair the beneficial effects of ASC in cell therapy. It is then essential to develop new strategies that contribute to the distinction between these two cell types. In this study, we performed functional assays, high-throughput RNA sequencing (RNA-Seq) and quantitative PCR (qPCR) to find new markers that can distinguish ASC and FIB. We showed that ASC have adipogenic and osteogenic differentiation capacity and alkaline phosphatase activity, not observed in FIB. Gene expression variation analysis identified more than 2000 differentially expressed genes (DEG) between these two cell types. We validated 16 genes present in the list of DEG, including the alkaline phosphatase gene (ALPL). In conclusion, we showed that ASC and FIB have distinct biological properties as demonstrated by alkaline phosphatase activity and differentiation capacity, besides having different gene expression profiles.
