Loose skin

Peripheral neuropathy characterized by rapidly increasing numbers of patients is commonly diagnosed via analyzing electromyography signals obtained from stimulation-recording devices. However, existing commercial electrodes have difficulty in implementing conformal contact with skin and gentle detachment, dramatically impairing stimulation/recording performances. Here, we develop on-skin patches with polyaspartic acid-modified dopamine/ethyl-based ionic liquid hydrogel (PDEH) as stimulation/recording devices to capture electromyography signals for the diagnosis of peripheral neuropathy...

Collagen content and collagen fiber architecture in the skin of Shamo chickens were compared between sexes and body parts. Cervical, thoracic, dorsal, femoral, and crural skin samples were collected and their collagen content was analyzed. Collagen fiber specimens were prepared for scanning electron microscopy using the cell maceration method with a NaOH solution. Sex differences in collagen content were only observed in the femoral skin of mature chickens, but not in 10-week-old chicks. The difference in collagen content between body parts was obvious; femoral and crural skin had higher collagen content than those of other parts in both sexes...

INTRODUCTION/AIMS: Vascular thrombosis is prevalent among patients with polyneuropathy, organomegaly, endocrinopathy M-protein, and skin changes (POEMS) syndrome. The endothelial cells in the endoneurium are often hypertrophied and the lumen is frequently occluded. Consequent local hypoxia may increase vascular endothelial growth factor (VEGF), which induces hypercoagulation and vascular permeability. METHODS: This study presents two patients in the fifth decade of life, who had rare nerve biopsy findings of vascular occlusion mainly by platelets...

Bioaccumulation of naturally produced ciguatoxin (CTX), such as that in ciguatera poisoning, continues to be a subject of great interest. In this condition, CTX is ingested by subtropical and tropical reef fish. Humans consume the fish species, and CTX is absorbed through the gastrointestinal tract and binds voltage-gated sodium channels on nerve terminals to cause neurological, gastrointestinal, cardiac, and rare dermatological clinical manifestations. In this present case, we discuss a 65-year-old female who presented with acute loose bowel movements and generalized pruritus of her anterior chest wall, abdomen, and bilateral upper and lower extremities 48 hours after consumption of amberjack fish...

The skin has multiple functions, and capillaries can penetrate the epidermis to shorten the diffusion path while allowing maintenance of overall epidermal thickness for nonrespiratory roles. However, a method for quantifying the capillary penetration extent is lacking. Such a method may facilitate making comparisons and detecting associations, potentially making the extent a useful variable in biological studies. We quantified the extent as the ratio of the average minimum thickness of epidermis overlying each capillary to the average epidermal thickness along a skin section and then explored its performance in the Emei mustache toad, Leptobrachium boringii, a species in which breeding males with loose skin call and fight each other with maxillary spines underwater...

Employed for the first time in 1986, DNA profiling is nowadays established as one of the most widely used forensic techniques worldwide. However, until today, no efficient sampling technique existed to collect DNA from human skin cells from a large area, not to say from the floor of an entire room. This has been extremely unfortunate, as there is enormous forensic potential in these DNA traces from the ground to provide clues as to who has been present at a particular location, i.e. at the crime scene. By desquamation, humans loose several millions of skin cells per day, everywhere they stand, sit or walk; and they can do little about it...

Bacterial cellulose (BC) is a promising material for use as an artificial skin in wound healing application, however, its applications are limited due to its poor malleability. Incorporating non-cellulosic polysaccharides such as dextran and xyloglucan (XG) may enhance its respective wound healing and malleability. This study presents a novel in situ biopreparation method to produce BC-based hybrid hydrogels containing dextran (BC-D) and xyloglucan-dextran (BC-XG-D) with unique mechanical and rheological properties...

BACKGROUND: This is the first clinical trial to investigate the effectiveness of maggot debridement therapy (MDT) for full-thickness burn injuries in comparison to conventional silver dressings. METHODS: Thirty-one cases with full-thickness (grade III based on ICD-10 classifications version 2019) burns were assigned into larval therapy (15 cases) and conventional treatment (16 cases) groups. Participants in the MDT group have received loose larvae on days 0, 2, 4, and 6, while controls received a conventional regimen comprised of sharp debridement, silver sulfadiazine, antibiotic therapy, and offloading every day...

In this study, we present the first spatial transcriptomic atlas of Atlantic salmon skin using the Visium Spatial Gene Expression protocol. We utilized frozen skin tissue from four distinct sites, namely the operculum, pectoral and caudal fins, and scaly skin at the flank of the fish close to the lateral line, obtained from two Atlantic salmon (150 g). High quality frozen tissue sections were obtained by embedding tissue in O.C.T media prior to freezing and sectioning. Further, we generated libraries and spatial transcriptomic maps, achieving a minimum of 80 million reads per sample with mapping efficiencies ranging from 79...

Lower blepharoplasty is one of the most commonly performed facial plastic surgeries and can be approached through many different techniques to improve perceived aging and fatigue due to prominent eyelid fat pads, deep tear troughs, loose eyelid skin, and global periorbital deflation. The technique discussed herein is a personal approach to lower eyelid rejuvenation surgery by the senior author, focusing on volume preservation with conservative resection and transposition of lower eyelid fat pads, muscle preservation, and microfat grafting...

Diabetic foot ulcers, a common complication of diabetes mellitus, significantly impact patients' quality of life and impose a substantial economic burden on healthcare systems. However, the currently used treatments are associated with various challenges and the traditionally used dressings lack functional efficacy. Oxidative stress is believed to play a vital role in diabetic wound healing. Therefore, nicotinamide mononucleotide (NMN), which is known for its antioxidant properties, offers the potential to accelerate the wound-healing process...

BACKGROUND: Identifying patients at risk of severe allergic reactions and/or low threshold of reactivity is very important, particularly for staple foods like egg. METHODS: One hundred and fifty children underwent double-blind placebo-controlled food challenge (DBPCFC) to baked egg (BE), skin prick testing and blood collection for serology and basophil activation test (BAT). Patients who passed BE DBPCFC underwent loosely cooked egg (LCE) DBPCFC. Severity of allergic reactions was classified following Practall guidelines and threshold dose was determined during DBPCFC...

Extensive studies have demonstrated critical roles of Regnase-1 in skin inflammation; however the role of N4BP1, a member of Regnase-1 family, in skin is largely unexplored. Here, we found that N4BP1 was highly expressed in skin and its expression was further increased upon skin injury. Compared to wildtype mice, N4BP1 deficient mice showed severe skin injury upon tape-stripping and burns. Overexpression of N4BP1 in HaCaT cells caused more cuboidal with higher cell-to-cell packing, while reduced expression of N4BP1 made cells become more spindle shaped and loosely packed...

ANIMALS: 3 horses (cases 1, 2, and 3) and 1 pony (case 4) with histologically confirmed ABC. CLINICAL PRESENTATION: All cases had mandibular swelling with intact adjacent skin. Cases 1 to 3 had a body condition score of 3/5 and case 4 had 2/5 and showed quidding during mastication and, at oral examination, large interdental spaces and loose elements adjacent to the swelling...

Dandruff is a common scalp condition affecting almost half of the world's population. Despite its high prevalence, the exact pathophysiology is not well established and is understood to be multifactorial, with factors such as fungal colonisation, sebaceous gland activity and individual factors being implicated. There is a need for an effective and safe shampoo that can target the above factors. Hence, we have developed a shampoo formulation with properties of oil control, moisturising, non-irritative, anti-fungal, anti-microbial, and itch relieving...

The heterogeneity and continuous cracking of the static solid electrolyte interphase (SEI) are one of the most critical barriers that largely limit the cycle life of lithium (Li) metal batteries. Herein, we report a fatigue-free dynamic supramolecular ion-conductive elastomeric interphase (DSIEI) for a highly efficient and dendrite-free lithium metal anode. The soft phase poly(propylene glycol) backbone with loosely Li+ -O coordinating interaction was responsible for fast ion transport. Simultaneously, the supramolecular quadruple hydrogen bonds (H-bonds) in the hard phases endow the elastomeric interphase with mechanical enhancement, while gradient H-bonds can dissipate strain energy via the sequential bonding cleavage...
