Yujin Kim, Junghoon Kim, Hyeryon Son, Youngjin Choi
The paper proposes a novel apparatus to measure the dynamic elasticity of human limb in order to help the design and fabrication of the personalized prosthetic socket. To take measurements of the dynamic elasticity, the desired force generated as an exponential chirp signal in which the frequency increases and amplitude is maintained according to time progress is applied to human limb and then the skin deformation is recorded, ultimately, to obtain the frequency response of its elasticity. It is referred to as a Dynamic Elasticity Measurement Apparatus (DEMA) in the paper...

Au nanoparticles (AuNPs) as signal reporters have been utilized in colorimetric in vitro diagnostics (IVDs) for decades. Nevertheless, it remains a grand challenge to substantially enhance the detection sensitivity of AuNP-based IVDs as confined by the inherent plasmonics of AuNPs. In this work, we circumvent this confinement by developing a unique dual-functional AuNPs that were engineered by coating conventional AuNPs with ultrathin Pt skins of sub-10 atomic layers (i.e., Au@Pt NPs). The Au@Pt NPs retain the plasmonic activity of initial AuNPs, while possess ultrahigh catalytic activity enabled by Pt skins...

Grape color somatic variants that can be used to develop new grapevine cultivars occasionally appear associated to deletion events of uncertain origin. To understand the mutational mechanisms generating somatic structural variation in grapevine, we compared the Tempranillo Blanco (TB) white berry somatic variant to its black berry ancestor, Tempranillo Tinto. Whole-genome sequencing (WGS) uncovered a catastrophic genome rearrangement in TB that caused the hemizygous deletion of 313 genes, including the loss of the functional copy for the MYB transcription factors required for anthocyanin pigmentation in the berry skin...

This study characterizes the scatter-specific tissue contrast that can be obtained by high spatial frequency (HSF) domain imaging and cross-polarization (CP) imaging, using a standard color imaging system, and how combining them may be beneficial. Both HSF and CP approaches are known to modulate the sensitivity of epi-illumination reflectance images between diffuse multiply-scattered and superficially backscattered photons, providing enhanced contrast from microstructure and composition than what is achieved by standard wide-field imaging...

BACKGROUND: Hypopigmentation is a troublesome often-permanent sequelae after burn injury, particularly in dark races. A number of methods have been described to treat this phenomenon. In this work, we are going to study the effect of E light (intensive pulsed light+radiofrequency+cooling) in repigmentation of partial thickness and full thickness burn wounds in adult patients and light microscopic changes of biopsy material at various stages of repigmentation. PATIENTS AND METHODS: In this study, 24 patients with postburn hypopigmentation were selected and E light was used, using different filters, according to the skin color...

Importance: Patients with germline mutations in BAP1 may develop several flesh-colored melanocytic BAP1-mutated atypical intradermal tumors (MBAITs). These tumors generally develop earlier than other BAP1-associated tumors, highlighting an important role for dermatologists in identifying and screening patients with a history suggestive of a germline mutation. Objective: To describe 8 new families with germline mutations in BAP1 and provide a comprehensive review of reported cases...

INTRODUCTION: Composite injuries of the volar surfaces of fingers are frequently associated with digital vessel and nerve damage. Flow-through glabrous flaps can provide esthetic tissue coverage as well as revascularization, and using a neurovascular flap, allows primary reconstruction of the digital nerve. METHODS: Between June 2010 and August 2014, we prospectively studied the use of Microsurgical flow-through glabrous flaps to achieve simultaneously digital revascularization and soft tissue coverage in 13 fingers of 12 patients who experienced volar injuries, comprising 6 great toe fibular flaps, 3 medial plantar flaps, 1 pedis medialis flap, and 3 hypothenar flaps...

Age is a fundamental social dimension and a youthful appearance is of importance for many individuals, perhaps because it is a relevant predictor of aspects of health, facial attractiveness and general well-being. We recently showed that facial contrast-the color and luminance difference between facial features and the surrounding skin-is age-related and a cue to age perception of Caucasian women. Specifically, aspects of facial contrast decrease with age in Caucasian women, and Caucasian female faces with higher contrast look younger (Porcheron et al...

There is accumulating evidence that interactions between epidermal melanocytes and stromal cells play an important role in the regulation of skin pigmentation. In this study we established a pigmented dermo-epidermal skin model (melDESS) of human origin to investigate the effects of distinct stromal cells on melanogenesis. melDESS is a complex, clinically relevant skin equivalent composed of an epidermis containing both melanocytes and keratinocytes. Its dermal compartment consisted either of adipose tissue-derived stromal cells (ASC), dermal fibroblasts, or a mixture of both cell types...

BACKGROUND: An accurate way to determine skin pigmentation is to acquire the spectral reflectance of a skin sample and to quantify chromophores by reverse calculation from physical models of light propagation. Therefore, we tested a new hyperspectral imaging device and software suite, the SpectraCam(®) system, and evaluated its accuracy to quantify skin chromophores. METHODS: Validation of the SpectraCam(®) system was performed by, firstly, comparing the known and the acquired reflectance spectra of color phantoms...

Certain potato cultivars are capable of producing anthocyanin pigments in the potato skin and flesh and those pigments have been shown, together with other phytochemicals, to promote good health. Six common anthocyanidins (cyanidin, delphinidin, petunidin, pelargonidin, malvidin and peonidin) were analyzed weekly for 15weeks in red- and purple-fleshed potato cultivars (Red Emma, Königspurpur, Valfi and Blaue de la Mancha) grown in field conditions using a validated LC-(+ESI)MS/MS method. Pelargonidin was the major type detected in red-fleshed cultivars whereas petunidin was the major type detected in the purple ones...

The phasor approach to fluorescence lifetime imaging microscopy (FLIM) is used to identify different types of tissues from hematoxylin and eosin (H&E) stained basal cell carcinoma (BCC) sections. The results suggest that working directly on the phasor space with the clustering assignment achieves immunofluorescence like simultaneous five or six-color imaging by using multiplexed fluorescence lifetimes of H&E. The phase approach is of particular effectiveness for enhanced visualization of the abnormal morphology of a suspected nidus...

Ninety years old male was admitted to hospital due to breathlessness. The prominent findings were extensive blue-grey skin pigmentation and large left chylothorax. Drug induced lupus was diagnosed due to either minocycline chronic treatment or no alternative illness to explain his sub-acute disease. Minocycline therapy was stopped with gradual improvement of pleural effusion and skin discoloration. This case is the first presentation of minocycline induced lupus with chylothorax.

The purpose of this study was to validate the already existing Racial Microaggression in Counseling Scale (RMCS) when the term 'therapist' was replaced with 'physician', thus constituting the modification as the Racial Microaggression in Medical Practice Scale (RMMPS). Racial microaggressions work at reinforcing inferior social status on a cognitive level. Unlike overt racism, messages behind microaggression are subtler and more every day. A lack of acceptance, respect, and regard emerges from interactions in medical contexts as there are layers of in-group and out-group statuses at play (e...

As African indigenous cattle evolved in a hot tropical climate, they have developed an inherent thermotolerance; survival mechanisms include a light-colored and shiny coat, increased sweating, and cellular and molecular mechanisms to cope with high environmental temperature. Here, we report the positive selection signature of genes in African cattle breeds which contribute for their heat tolerance mechanisms. We compared the genomes of five indigenous African cattle breeds with the genomes of four commercial cattle breeds using cross-population composite likelihood ratio (XP-CLR) and cross-population extended haplotype homozygosity (XP-EHH) statistical methods...
