“…Lipase hydrolysis has been shown to occur intensively in the pilosebaceous units that produce glycerol and free fatty acids from sebum glycerides (Fluhr et al, ). The existence of lipase hydrolysis by the skin's flora of microorganisms is well known (dos Santos Rodrigues et al, ; Freinkel & Shen, ; Ro & Dawson, ), and there is evidence that triglyceride hydrolysis also occurs within the stratum corneum (Fluhr et al, ; Scheimann, Knox, Sher, & Rothman, ). However, only limited quantitative data are available (Freinkel & Shen, ).…”

The use of vegetable butters and oils shows promising results in the treatment of skin wounds, as they have an effective impact on the phases of the wound-healing process through their antimicrobial, anti-inflammatory, and antioxidative activities and by promoting cell proliferation, increasing collagen synthesis, stimulating dermal reconstruction, and repairing the skin's lipid barrier function.In this article, in vitro and in vivo studies of argan (Argania spinosa), avocado (Persea americana), black cumin (Nigella sativa), calophyllum (Calophyllum inophyllum), coconut (Cocos nucifera), cranberry (Vaccinium macrocarpon), grape (Vitis vinifera), green coffee (Coffea arabica), lentisk (Pistacia lentiscus), linseed (Linum usitatissimum), lucuma (Pouteria lucuma), mango (Mangifera indica), olive (Olea europaea), pomegranate (Punica granatum), pumpkin (Cucurbita pepo), rapeseed (Brassica napus), sea buckthorn (Hippophae rhamnoides), and sunflower (Helianthus annuus) oils were reviewed. In many cases, vegetable oils proved to be more effective than synthetic wound-healing compounds used as controls.The fatty-acid components of vegetable oils are assumed to play a major role in the wound-healing process, in particular polyunsaturated fatty acids such as linoleic acid.Evidence shows that oils with a higher linoleic to oleic acid ratio are more effective for lipid barrier repair. However, in depth studies are needed to gain knowledge about vegetable oils' effects on the skin and vice versa. KEYWORDSfatty acids, skinskin woundskin wound healingvegetable buttersvegetable oils

“…Free fatty acids, like oleic acid that accounts for the greatest proportion of the fatty acid components of olive oil triglycerides, are welldocumented penetration enhancers that increase TEWL when applied to the skin (38)(39)(40). Whilst triglycerides themselves do not penetrate the skin, as indicated by the sharp reduction in lipid esters in the skin following tape-stripping, lipases derived from the resident skin flora breakdown triglycerides to release glycerol and free fatty acids such as linoleic acid and oleic acid (41,42). Glycerol is an important moisturising factor (humectant) found in the SC, increased levels of which increase skin hydration (43).…”

Topical oils on baby skin may contribute to development of childhood atopic eczema. A pilot, assessor-blinded, randomized controlled trial assessed feasibility of a definitive trial investigating their impact in neonates. One-hundred and fifteen healthy, full-term neonates were randomly assigned to olive oil, sunflower oil or no oil, twice daily for 4 weeks, stratified by family history of atopic eczema. We measured spectral profile of lipid lamellae, trans-epidermal water loss (TEWL), stratum corneum hydration and pH and recorded clinical observations, at baseline, and 4 weeks post-birth. Recruitment was challenging (recruitment 11.1%; retention 80%), protocol adherence reasonable (79-100%). Both oil groups had significantly improved hydration but significantly less improvement in lipid lamellae structure compared to the no oil group. There were no significant differences in TEWL, pH or erythema/skin scores. The study was not powered for clinical significance, but until further research is conducted, caution should be exercised when recommending oils for neonatal skin.

“…Therefore, phage PVP-SE1 can be used to point out bad microbiological conditions of stored food once spoilage bacteria present in foods could present an intermediary color, the purple color, that indicate unsatisfactory sanitary food condition. On the other hand, the change color from blue to red in Salmonella presence indicate unsafe condition of the food because the presence of the pathogen render the food a risk for health [24].…”

Polydiacetylene (PDA) compound has unique chromatic properties when embedded in methylcellulose base. Therefore, this could be used as intelligent packaging. PDA exhibits blue-to-red color transition under certain stimuli, which was caused by alterations in PDA conjugation length backbone. For a specific color modification, bio-recognition tools were covalently linked with PDA. In this work, a broad-spectrum virulent phage (PVP-SE1) was used as a biorecognition element to detect Salmonella cells due to PDA color change. A series of experiments were performed to monitor colorimetric response. Consequently, chromatic immunoassay could be significant in increasing potential applications of PDA intelligent packaging.
