BACKGROUND Onychodystrophy refers to the various abnormalities in nail morphology due to changes in the attachment of the nail plate, changes in nail surface or color. The treatment principle of onychodystrophy largely relies on the discovery and verification of the cause. However, preventive treatment methods offer little help to the patient due to poor compliance, and the effect of corticoste...

This study investigates the hypothesis that tomtits are significantly less susceptible to 1080 poison operations when cereal rather than carrot bait applications are used, both at relatively low sowing rates. We made counts of territorial male tomtits along transects during standard 1080 possum control operations in 2001 to 2003. The transects had 3–5 kg ha sowing rates of either carrot or cere...

bryogenesis is usefu1 for isolating genes expressed during embryogenesis, as embryegenic competence and the expressien of certain embryo-specific genes increases with increased stress. Fluorescent differential display (FDD) was perfonmed to isolate stress-induced genes in carrot somatic embryos, and five genes were isolated as embryonic tissue-specific genes. One ofthese genes was expressed unt...

The prevalence of non-autonomous class II transposable elements (TEs) in plant genomes may serve as a tool for relatively rapid and low-cost development of gene-associated molecular markers. Miniature inverted-repeat transposable element (MITE) copies inserted within introns can be exploited as potential intron length polymorphism (ILP) markers. ILPs can be detected by PCR with primers anchored...

BACKGROUND Patients sensitized to birch pollen frequently suffer from a food allergy to plant foods such as celery, carrots, or hazelnut. One of the main manifestations of birch pollen-related food allergy is the oral allergy syndrome. Skin tests and allergen-specific immunoglobulin (Ig) E determinations are poor predictors of such reactions when assessed by double-blind placebo-controlled food...

This experimental work aimed to evaluate the potential of high pressure homogenization (HPH) to inactivate Saccharomyces cerevisiae 635 inoculated both in apricot and carrot juices. The sensitivity of the yeast was evaluated both in relation to its initial inoculum level (about 3.0 and 6.0 Log(10) cfu/ml) and number of passes applied at 100 MPa. Moreover, the effects of repeated pressure treatm...

Carotenoids are synthesized in prokaryotic and eukaryotic organisms. In plants and algae, these lipophilic molecules possess antioxidant properties acting as reactive oxygen species scavengers and exert functional roles in hormone synthesis, photosynthesis, photomorphogenesis and in photoprotection. During the past decade almost all carotenogenic genes have been identified as a result of molecu...

Root-knot nematodes, particularly Meloidogynejavanica (Treub.) Chitwood, 1949 and M. incognita (Kofoid and White) Chitwood, 1949, are among the most important pathogens of carrots (Daucus carota L.) in Brazil. They damage tap roots by galling, digitation, and constriction, resulting in lower market value (3). Even low soil densities of root-knot nematodes have been reported to reduce marketable...

In previous in vitro experiments using an Instron instrument, each test food was found to have characteristic textural properties. In vivo experiments were now made (1) to determine the degree to which variations in the vertical jaw movements during the crushing phase of mastication can be explained by the inherent properties of the foodstuff being chewed, and (2) to establish the degree to whi...

Plant carotenoids are synthesized and accumulated in plastids through a highly regulated pathway. Lycopene β-cyclase (LCYB) is a key enzyme involved directly in the synthesis of α-carotene and β-carotene through the cyclization of lycopene. Carotenoids are produced in both carrot (Daucus carota) leaves and reserve roots, and high amounts of α-carotene and β-carotene accumulate in the latter. In...
