Mafenide acetate is used in some burn wounds for its ability to penetrate eschar but requires frequent uncomfortable dressing changes for its application. The authors hypothesize that hydrofiber dressings will hold mafenide acetate solution for an extended period of time and maintain antimicrobial activity longer than traditional gauze, thus possibly obviating the need for frequent dressing changes. Four experimental arms included: 1) hydrofiber, stored on a dry well plate as control, 2) gauze saturated with 2...

Sulfur mustard (SM; mustard gas) is a classic chemical warfare agent that has been used in several wars and is still a potential threat especially in the Middle-East region. Victims experience acute symptoms in air-exposed organs including skin, respiratory tract and the eyes. Survivors of the acute stage might develop chronic or delayed-onset complications in the exposed organs. The exact mechanism(s) of SM-induced tissue damage is still unknown, however DNA alkylation and oxidative damage are the most relevant mechanisms...

OBJECTIVE: Xerosis is a serious problem among the very old. It is a dermatological challenge caused by significant alterations in stratum corneum (SC) function and structure. Two negative changes in aged skin are: (i) the enhanced skin surface pH and (ii) the altered SC lipid content, composition and ordering. METHODS: Therefore, we investigated the way in which an acidic skin care product with different plant oils affects SC function, structure and lipid profile in older subjects with dry skin...

Pemphigoid and pemphigus diseases as well as Stevens-Johnson syndrome present as vesiculobullous disorders of the skin and may additionally involve both the oral cavity and the ocular surface. Ocular involvement ranges from mild irritation and dry eye disease to chronic conjunctivitis, symblepharon, eyelid malposition, ocular surface scarring and severe visual loss. In addition to diagnostic assessments, ophthalmologists must treat the dry eye and Meibomian gland dysfunction components of these diseases using a stepladder approach, including eyelid hygiene and lubricants...

Electroencephalography (EEG) is a procedure that records brain activity in a non-invasive manner. The cost and size of EEG devices has decreased in recent years, facilitating a growing interest in wearable EEG that can be used out-of-the-lab for a wide range of applications, from epilepsy diagnosis, to stroke rehabilitation, to Brain-Computer Interfaces (BCI). A major obstacle for these emerging applications is the wet electrodes, which are used as part of the EEG setup. These electrodes are attached to the human scalp using a conductive gel, which can be uncomfortable to the subject, causes skin irritation, and some gels have poor long-term stability...

BACKGROUND: The hybrid grape cultivar Isabel (Vitis labrusca x V. vinifera) is widely grown in the Black Sea region of Turkey and constitutes an important part of the diet of its inhabitants. Phenological and ampelographical studies of the grape have previously been performed, but there are no data concerning nutrient composition. Its nutrient content needs to be investigated to ascertain its potential economic and nutritional uses in the region. RESULTS: The concentrations (range, g kg(-1) fresh weight) of major soluble sugars (fructose; 2...

Perineal wounds in dogs present a challenge due to limited local availability of skin for closure and constant exposure to fecal contaminants. This report describes temporary rectal stenting in two dogs following severe perineal wounds. Dog 1 presented with a 4 × 4 cm full-thickness perineal slough secondary to multiple rectal perforations. A 12 mm internal diameter endotracheal tube was placed per-rectum as a temporary stent to minimize fecal contamination. The stent was removed 18 days after placement, and the perineal wound had healed at 32 days post-stent placement, when a minor rectal stricture associated with mild, intermittent tenesmus was detected...

OBJECTIVE: Premature aging syndromes are very rare and most often hereditary. Initially purely descriptive entities, these syndromes are now much better understood genetically and pathophysiologically and can now be classified according to the mechanisms involved. They often manifest as a pigmented skin dry, atrophic and sclerotic. There is no treatment for these conditions apart from that of their complications (frequent ulceration). OBSERVATIONS: Forty-five years of patient follow-up in dermatology for premature aging syndrome, addressed in our service for podiatric care...

Significant decreases in hormonal levels at menopause induce physiological and functional discomfort in the skin. Representative changes at menopause are based on "so-called dry skin". However, there is no evidence to explain the mechanism, even though hydration of the stratum corneum (SC) in women at menopause is comparable with that at pre-menopause but is enhanced by hormone replacement therapy. This study objective was to evaluate structural and functional changes in the SC in ovariectomized mice model of menopause...

Motivated by the importance of the heterogeneous chemistry of squalene contained within skin oil to indoor air chemistry, the surface reaction of squalene with gas-phase ozone has been investigated. Using direct analysis in real time mass spectrometry (DART-MS) to monitor squalene, the reactive uptake coefficients were determined to be (4.3 ± 2.2) × 10(-4) and (4.0 ± 2.2) × 10(-4) for ozone mixing ratios (MRO3) of 50 and 25 ppb, respectively, on squalene films deposited on glass surfaces. At an MRO3 of 25 ppb, the lifetime for oxidation was the same as that in an indoor office with an MRO3 between 22 and 32 ppb, suggesting that O3 was the dominant oxidant in this indoor setting...
