6. Malassezia globosa and restricta: breakthrough understanding of the etiology and treatment of dandruff and seborrheic dermatitis through whole-genome analysis.
Match Strength: 10.640
Dandruff and seborrheic dermatitis (D/SD) share an etiology dependent upon three factors: sebum, microbial metabolism (specifically, Malassezia yeasts), and individual susceptibility. Advances in microbiological and analytical techniques permit a more detailed understanding of these etiologic factors, especially the role of Malassezia. Malassezia are lipid-dependent and demonstrate adaptation allowing them to exploit a narrow niche on sebum-rich skin. Work in our and our collaborators' laboratories has focused on understanding these adaptations by detailed analysis of biochemistry and gene ... Read More »

8. Isolation of llama antibody fragments for prevention of dandruff by phage display in shampoo.
Match Strength: 9.662
As part of research exploring the feasibility of using antibody fragments to inhibit the growth of organisms implicated in dandruff, we isolated antibody fragments that bind to a cell surface protein of Malassezia furfur in the presence of shampoo. We found that phage display of llama single-domain antibody fragments (VHHs) can be extended to very harsh conditions, such as the presence of shampoo containing nonionic and anionic surfactants. We selected several VHHs that bind to the cell wall protein Malf1 of M. furfur, a fungus implicated in causing dandruff. In addition to high stability in ... Read More »

9. The Role of Sebaceous Gland Activity and Scalp Microfloral Metabolism in the Etiology of Seborrheic Dermatitis and Dandruff
Match Strength: 9.242
Most common scalp flaking disorders show a strong correlation with sebaceous gland (SG) activity. Early SG activity in the neonate results in microfloral colonization and cradle cap. After maternal hormonal control subsides, there is little SG activity until puberty, when the SG turns on under sex hormone control. When the SG activity increases, the present but low Malassezia population has a new food source and proliferates, resulting in the scalp itching and flaking common to greater than 50% of adults. Dry scalp flaking, dandruff, and seborrheic dermatitis are chronic scalp manifestations ... Read More »

15. Clinical Diagnosis of Common Scalp Disorders
Match Strength: 6.357
Scalp skin is unique on the body due to the density of hair follicles and high rate of sebum production. These features make it susceptible to superficial mycotic conditions (dandruff, seborrheic dermatitis, and tinea capitis), parasitic infestation (pediculosis capitis), and inflammatory conditions (psoriasis). Because these scalp conditions share similar clinical manifestations of scaling, inflammation, hair loss, and pruritus, differential diagnosis is critically important. Diagnostic techniques and effective treatment strategies for each of the above conditions will be discussed ... Read More »

16. A practical guide to scalp disorders.
Match Strength: 5.498
The scalp is unique among skin areas in humans, with high follicular density and a high rate of sebum production. The relatively dark and warm environment on the scalp surface provides a welcoming environment for the superficial mycotic infections associated with many scalp conditions and for parasitic infestation. Infections and infestations can occur when items such as fingers, combs, hats, or styling implements come into contact with the hair and scalp and introduce microorganisms. Inflammatory conditions may also produce changes in the scalp. Many common scalp conditions have similar ... Read More »

17. The use of hydroxy acids on the skin: characteristics of C8-lipohydroxy acid.
Match Strength: 5.403
The hydroxy acids are widely used in skin creams because of their exfoliating and rejuvenating effect on photoaged skin. As a member of this family, the salicylic acid derivative known in the literature as 2-hydroxy-5-octanoyl benzoic acid or beta-lipohydroxy acid has also been proposed as an exfoliant and as a treatment of photoaged skin and acne. This article reviews the effects of the hydroxy acids and compares them to those of the salicylic acid derivative. We propose the name C(8)-lipohydroxy acid (C8-LHA) for this derivative to differentiate it from other related compounds. The ... Read More »

20. Isolation and Expression of a Malassezia globosa Lipase Gene, LIP1.
Match Strength: 4.391
Dandruff and seborrheic dermatitis (D/SD) are common hyperproliferative scalp disorders with a similar etiology. Both result, in part, from metabolic activity of Malassezia globosa and Malassezia restricta, commensal basidiomycete yeasts commonly found on human scalps. Current hypotheses about the mechanism of D/SD include Malassezia-induced fatty acid metabolism, particularly lipase-mediated breakdown of sebaceous lipids and release of irritating free fatty acids. We report that lipase activity was detected in four species of Malassezia, including M. globosa. We isolated lipase activity by ... Read More »
