(wikipedia.org)

  • Phylogenetic reconstruction of Pyreae and the genus Malus, relative to major Rosaceae taxa, identified the progenitor of the cultivated apple as M. sieversii. (wikipedia.org)
  • species
  • Asymmetrical secondary alcohols and β-diketones form hollow wax nanotubes, while primary alcohols and symmetrical secondary alcohols form flat plates Although these have been observed using the transmission electron microscope and scanning electron microscope the process of growth of the crystals had never been observed directly until Koch and coworkers studied growing wax crystals on leaves of snowdrop (Galanthus nivalis) and other species using the atomic force microscope. (wikipedia.org)
  • The most common mimic is folliculitis produced by an overgrowth of the Malassezia species, often secondary to oral or systemic corticosteroids, or secondary to broad-spectrum antibiotics such as the tetracycline family used in acne. (wikipedia.org)
  • Cultivation of the species, most likely beginning on the forested flanks of the Tian Shan mountains, progressed over a long period of time and permitted secondary introgression of genes from other species into the open-pollinated seeds. (wikipedia.org)
  • Neviusia dunthornei is an extinct species of flowering plants in the Rosaceae family. (wikipedia.org)
  • The overall morphology and structure of the N. dunthornei leaves compare to the living species known as the Shasta snow-wreath (N. cliftonii), being broadly ovate, with secondary veins subopposite and a similar overall vein patterning. (wikipedia.org)
  • This disease in humans is usually caused by Demodex folliculorum (not the same species affecting dogs) and is usually called demodicosis which may have a rosacea-like appearance. (wikipedia.org)
  • sufferers
  • Rosacea tends to run in families and appears to be especially prevalent among those of northern European descent, according to results of a recent survey of 600 rosacea sufferers conducted by the National Rosacea Society. (rosacea.org)
  • Evidence suggests that heredity may indeed play a role in the development of this disorder, and that the children and other relatives of rosacea sufferers would be wise to be on the lookout for early signs as they grow older in order to seek diagnosis and treatment before the condition reaches more advanced stages. (rosacea.org)
  • dermatologic
  • This study's findings have tracked the link between the vascular system and the more permanent disfiguring effects of rosacea,' said Dr. Jonathan Wilkin, director of Dermatologic and Dental Products, U.S. Food and Drug Administration. (lymphedemapeople.com)
  • Efficacy
  • The purpose of this study is to assess the safety and efficacy of azelaic acid (AzA) foam, 15% topically applied twice daily for 12 weeks in subjects with papulopustular rosacea compared to its vehicle. (clinicaltrials.gov)
  • lesions
  • Demodicosis can manifest as lesions of two types: squamous, which causes dry alopecia and thickening of the skin, and pustular, which is the more severe form, causing secondary infection (usually by Staphylococcus), resulting in the characteristic numerous red pustules and wrinkling of the skin. (wikipedia.org)

  • family
  • Nearly 52 percent of those responding to the survey said someone else in their family has or did have rosacea, and 42 percent indicated they were of Irish, German or English ancestry. (rosacea.org)
  • Nearly 40 percent of the respondents indicated they had a family member who also suffered from rosacea. (rosacea.org)
  • The predisposing factors include age and family history of rosacea. (researchandmarkets.com)
  • These characters by themselves represent the Rosaceae family and with the addition of other characters the separation of the other related plant families can be obtained with the understanding that there are exceptions to most of these norms. (wikipedia.org)
  • leaves
  • Usually in the eastern US, when the rose motif is present with compound leaves and no representative characteristics of the other families in this group, it is probably a member of Rosaceae. (wikipedia.org)
  • On the secondary hosts, the fungus produces yellowish depressions on the leaves. (wikipedia.org)
  • therapeutic
  • Conclusion: Rosacea lymphoedema involving the eyelid, as in our case, is a rare complication and can present diagnostic and therapeutic challenges to the ophthalmologist. (lymphedemapeople.com)
  • tear
  • The keratitis associated with rosacea is most commonly inferior, presumably due to the accumulation of inflammatory cytokines in the tear film above the lower lid. (uiowa.edu)
  • disease
  • Eighteen percent had a brother or sister suffering from rosacea, while 13 percent had a grandparent with the disease and 16 percent had an aunt or uncle who was affected. (rosacea.org)
  • In men, they are related to high estrogen levels secondary to liver disease. (wikipedia.org)
  • skin
  • Almost everyone who gets diagnosed with rosacea is shocked that what looks like a teenage skin problem comes to visit them middle aged or even as a senior. (rosacea-support.org)
  • We think that long term damage to skin from the sun (photodamage) may play a role in causing this type of rosacea. (clinicaltrials.gov)
  • families
  • Rosaceae mostly have relatively showy, perfect flowers with a hypanthium and are often herbaceous, whereas the other families have relatively inconspicuous, unisexual flowers without an obvious hypanthium and are all woody (except for Cannabis & Humulus in the Cannabaceae). (wikipedia.org)
  • Among the basal core eudicots, Caryophyllales (especially Polygonaceae) are particularly significant, of the asterids the Asterales (especially Asteraceae), Ericales (especially Ericaceae) and Lamiales (especially Plantaginaceae), and of the rosids the Malpighiales (numerous families) and Rosales (especially Rosaceae).
