HIGHLIGHTS • Molecular analysis of aurofusarin biosynthesis in F. culmorum. Mycelial pigmentation depending on gene expression and accumulation. Pigmentation variations growth phase.

poor adhesion between two successive bituminous layers causes adverse effects on the structural strength of the pavement and develops a numbers of premature failure. to improve the adhesion, it is a general practice to apply a tack coat over an existing or newly constructed bituminous surface before laying another bituminous layer. the main objective of this study is to explore the influence of...

AIM Melanin pigmentation of the gingiva occurs in all ethnicities. Excessive pigmentation is an esthetic concern that has increased awareness about de pigmentation procedures. The purpose of the present study was to correlate skin color and gender with intensity and distribution of gingival melanin pigmentation in a group of South Indians. METHODS 200 male and female non smoking healthy subje...

DUNN and Charles (1937, p. 14) opens with an understated assessment on the state of developmental genetics at the time: “The processes which lead to the formation of patterns during ontogeny in animals are at present very imperfectly understood.” This was the first in a series of five articles that proposed that understanding the highly variable coat patterns of the mouse could provide a model ...

This paper presents the coating thickness effect on the stress distribution of a coated cylinder head. A typical thermal barrier coating was applied on a diesel engine cylinder head. Thus, the residual stress which occurred during the plasma thermal spraying was also considered. The coating system consisted of two layers a metallic bond coat and a ceramic top coat. The bond coat thickness is co...

BACKGROUND To assess the effect of smoking on lip and gingival pigmentation and also to assess the relationship of pigmentation with periodontal parameters. MATERIALS AND METHODS 109 smokers and an equal number of control subjects who were nonsmokers in the age range of 35 - 44 years comprised the study sample. All the participants were assessed for pigmentation on lip and gingiva and a total...

Since its use was first reported by 8rowne and Hogerzeil in 1962 ('0. /I), 8663, a synthesized phenazine dye, has proven to be an effective drug in the treatment of human leprosy and its use has become worldwide ( 2.7.9 " . 26. 3~. 39. 52. 5.1 ). The most significant and frequent side effect of this compound is an abnormal skin coloration. This can be divided into two types. One is an initial r...

background although, melasma is most prevalent among asian young women, and also darkly pigmented individuals are particularly prone to developing post inflammatory hyperpigmentation, to the best of our knowledge, there are rare or no studies about the association of melasma and post inflammatory hyperpigmentation. results we found out that 24.1% of patients without melasma had post-acne pigmen...

Multiple exposures to ultraviolet radiation (UVR) are the norm in nature and phototherapy. However, studies of the kinetics of pigmentation following UVA exposure have included only fair-skinned persons. The aim of this study was to investigate steady-state pigmentation and fading in 12 Scandinavians and 12 Indians/Pakistanis after 6 and 12 exposures on the back using broadband UVA and UVA1 wit...
