Gel polymer electrolytes (GPEs) based on semi-interpenetrating polymer network (IPN) structure for lithium-ion batteries were prepared by mixing boron-containing cross-linker (BC) composed of ethylene oxide (EO) chains, cross-linkable methacrylate group, and anion-trapping boron moiety with poly(vinylidene fluoride) (PVDF) followed by ultraviolet light-induced curing process. Various physical and electrochemical properties of the GPEs were systematically investigated by varying the EO chain leng

Structureless patterns or globules/clods with purple, red, or blue coloration can be useful findings when differentiating VLs from LMM on dermoscopy. Therefore, dermoscopic evaluation is a helpful noninvasive ancillary tool in the diagnosis of VL.

Oral tofacitinib monotherapy improves nail involvement associated with AA. Nail involvement is not a poor prognosis factor in hair regrowth with tofacitinib treatment and there is no evident relationship between nail and hair responses.

Abstract The effects of compatibilizer and fillers on the mechanical properties and dispersion state of droplets of polypropylene (PP)/polylactide (PLA) blends were investigated. Two blended composite systems, i.e. PP‐rich (80/20) containing microcrystalline cellulose (MCC) modified with silane (m‐MCC) and PLA‐rich (20/80) containing MCC were prepared by melt compounding using a twin‐screw extruder. The structural differences between MCC and m‐MCC were confirmed using Fourier transform infrared

Women in Suwon (Korea) were found to have a better profile of biophysical parameters than women in the 3 Chinese cities, which might be attributed to cosmetic habits, besides age and climatic factors. The fact that appropriate cosmetic habits are associated with favorable skin biophysical parameters underscores the importance of daily skin care routine in preserving skin functions.

Objectives : The objective of this study is to find out the method and effects of fire needling on frozen shoulder in China. Methods : We searched journals using the China National Knowledge Infrastructure(CNKI) and PubMed. The keywords were a combination of "fire needling", "fire needle", "burning acupuncture", "frozen shoulder", "adhesive capsulitis", "periarthritis". Results : There were 23 studies finally selected, 7 were case control studies and 16 were case series studies. There were 9 out

Conjugation of substrate proteins with ubiquitin (Ub), a 76 amino acid protein, was discovered as the first major translational modification responsible for protein degradation. Ubiquitination occurs as a cascade among ubiquitin-activating enzyme (E1), ubiquitin-conjugating enzyme (E2), and ubiquitin ligases (E3) enzymes that transfer and covalently conjugate Ub to the lysine (Lys) residue and α-amino group in methionine (Met) residues of substrates. Following the initial conjugation, Ub itself

Eccrine syringofibroadenoma (ESFA) is a rare, benign adnexal neoplasm which usually manifests as a solitary nodule on the extremities of elderly patients. Few case reports have described an association between ESFA and carcinomas including squamous cell carcinoma, porocarcinoma, and basal cell carcinoma. A 66-year-old male presented with a pruritic, erythematous brownish solitary plaque with crusted and verrucous surface on the extensor side of the right thigh. The lesion developed 6 to 7 years

Several dermatoses have been reported in association with Becker's nevus. Eczematous dermatitis associated with Becker's nevus is extremely rare, described in only two previous case reports. We report a case of 21-year-old male with recurrent eczema lesions which were always localized within the underlying Becker's nevus lesion. This case may be explained as a Wolf's isotopic response-like phenomenon.

Hair follicle nevus (HFN) is a rare, benign, follicular hamartoma that most frequently presents as a congenital nodule on the face. We experienced a rare case of HFN on the neck of a 14-year-old boy and performed a pilot immunohistochemical study with cytokeratin 19 (CK19) to compare the staining pattern of hair follicles in HFN and its differential diagnoses, accessory tragus, cervical chondrocutaneous branchial remnants (CCBR) and trichofolliculoma. With hematoxylin and eosin stain, HFN showed

Although a few reports have noted the concurrent presentation of morphea and vitiligo at distinctly separate sites in the same patient, it is extremely rare that these two conditions occur at the same sites in a patient. We report the case of a 10-year-old Korean girl with morphea and vitiligo and those lesions occurred at the same sites and progressed simultaneously. An autoimmunity and a cutaneous mosaicism was considered to be involved in such an unique presentation as the pathogenesis is con

To the Editor: Livedoid vasculopathy (LV) is a rare, chronic, ulcerative disease that significantly impairs the quality of life of patients.1Micieli R. Alavi A. Livedoid vasculopathy: an updated review.Curr Dermatol Rep. 2018; 7: 125-135Crossref Scopus (4) Google Scholar Previous case series have described the association between LV and various hypercoagulable conditions, including methylenetetrahydrofolate reductase (MTHFR) polymorphism and hyperhomocysteinemia.1Micieli R.

In HE or PPP, lesions with hyperkeratotic morphology can be predicted to respond well to alitretinoin regardless of diagnosis.
