BACKGROUND Treatments for alopecia are in high demand, but not all safe and reliable. Dalteparin protamine microparticles (D/P MPs) can effectively carry growth factors (GFs) platelet-rich plasma (PRP). OBJECTIVE To identify the effects of PRP-containing D/P MPs (PRP&D/P on hair growth. METHODS & MATERIALS Participants were 26 volunteers with thin who received five local treatments 3 mL PRP&D/P (13 participants) or PRP saline (control, 13 at 2- to 3-week intervals evaluated 12 weeks....
A new method for easy detection of functional lymphatic vessels in the superficial layer is reported. In a clinical trial, lymphography using indocyanine green dye near-infrared fluorescence labeling lymphaticovenular anastomoses was performed 5 patients with lymphedema. The technique simple and enables minimally invasive operation to be performed. results indicate that this useful acceptance as one examinations evaluation
Adipose tissue-derived stromal cells (ATSCs) have recently gained widespread attention as a potential alternate source to bone marrow–derived mesenchymal stem with proliferative capacity and similar ability undergo multilineage differentiation. In this study, we evaluated the effectiveness of freshly isolated autologous ATSCs-containing atelocollagen matrix silicon membrane (ACMS) on wound healing diabetic (db/db) mice. Cultured ATSCs from mice secreted significant amounts growth factors...
Lymphedema is known to be caused by many pathologic conditions; however, its diagnostic and therapeutic strategies remain unestablished. In this study, we investigated the usefulness of a novel lymphographic method based on fluorometric sensing using indocyanine green (ICG) dye for imaging lymphatic vessels rat models. The real-time system enabled visualization superficial with diameter 0.1 mm in 33 frames/second. addition, morphologic changes radiation-induced lymphedema model were detected...
Biomaterials traditionally used for wound healing can act as a temporary barrier to halt bleeding, prevent infection, and enhance regeneration. Hydrogels are among the best candidates owing their moisture retention drug-releasing properties. Photo-polymerization using visible light irradiation is promising method hydrogel preparation since it easily control spatiotemporal reaction kinetics rapidly induce single-step under mild conditions. In this study, photocrosslinked gelatin hydrogels...

ABSTRACT The aim of this study was to evaluate the potential accelerating effects an adipose tissue‐derived stromal cells (ATSC)‐containing atelocollagen matrix with silicone membrane (ACMS) for repairing mitomycin C‐treated healing‐impaired wounds. Mitomycin C applied full‐thickness skin incisions in create a wound model rat. After thoroughly washing out from wound, ACMS alone or ATSC‐containing Histological sections wounds were then prepared at indicated time periods after treatments....
We examined the impact on urethral stricture complexity at urethroplasty of previous transurethral treatments such as dilation, urethrotomy and stenting, which are most commonly performed when treating male stricture.We retrospectively reviewed records 45 males who had undergone before urethroplasty. compared urethrography findings initial diagnosis with those Males failed hypospadias repair, lichen sclerosis or a history prior were excluded from analysis. considered increased if number...
A distal phalanx may fracture in an atypical shape after high-energy trauma. 61-year-old man sustained open of the his left thumb while using a power saw. The occurred coronal plane and volar bone fragment was dislocated under traction by flexor pollicis longus tendon. patient underwent surgery day injury. flexion block pin inserted to reduce fragment, external force applied dorsal splint compress into fragment. removed 6 weeks postoperatively, active range motion exercises were started 8...
Abstract The purpose of this study was to evaluate effects human platelet‐rich plasma (PRP)‐containing fragmin/protamine microparticles (F/P MPs) as a protein carrier on neovascularization and granulation tissue formation. Frozen thawed PRP contains high concentrations various growth factors (GFs) F/P MPs effectively adsorb those GFs. Human microvascular endothelial cells (MVECs) dermal fibroblast (DFCs) were optimally grown in medium containing 4% the addition significantly maintained...
We aimed to evaluate the effectiveness of application an atelocollagen matrix containing autologous adipose tissue-derived stromal cells (ASCs) on wound healing in diabetic (db/db) mice. Cultured ASCs from db/db mice and db/+ secreted identical amounts growth factors, cytokines, type I collagen. proliferated at same rate as those When DiI-labeled were applied full-thickness round skin wounds backs mice, histological observation 2 weeks showed that red fluorescent-labeled tissues formed...
One of the features photoacoustic (PA) imaging is small-vessel visualization realized without injection a contrast agent or exposure to X-rays. For carrying out clinical studies in this field, prototype PA system has been developed. The utilizes technological platform FUJIFILM's ultrasound (US) mounting many-core MPU for enhancing image quality US B-mode and Doppler mode, which can be superposed onto images. By evaluating images prototyped system, applicability discussed. light source was on...
Xtend is one of the two telescopes onboard X-ray imaging and spectroscopy mission (XRISM), which was launched on September 7th, 2023. comprises Soft Imager (SXI), an CCD camera, Mirror Assembly (XMA), a thin-foil-nested conically approximated Wolter-I optics. A large field view 38′ × over energy range from 0.4 to 13 keV realized by combination SXI XMA with focal length 5.6 m. The employs four P-channel, back-illuminated type CCDs thick depletion layer 200 μm. chips are arranged in 2×2 grid...
Microvascular anastomosis using cyanoacrylate adhesive has a reputation among researchers as an alternative to conventional sutures. However, degree of ingenuity is required avoid the collapse vascular lumen for duration anastomosis. The aim this study was determine feasibility intravascular stenting (IVaS) temporary stent during sutureless microvascular with adhesive. Sixty male Fisher 344 rats were evenly divided into two groups. right superficial femoral arteries (RSFAs) transected in...
A 58-year-old Japanese male visited us with painful lesions on the lower lip, oral mucosa and genital region of an 8-month duration. Histological features lesion were almost consistent lichenoid tissue reaction. few intraepidermal acantholytic keratinocytes also seen in suprabasal clefts. Direct immunofluorescence exhibited cell surface immunoglobulin (Ig)G deposition linear fibrinogen at dermoepidermal junction. IgG anti-desmoglein (Dsg)3 antibody, but not anti-Dsg1 was detected patient's...
