Background & Aims: Tyrosinase is the most important enzyme in the production of pigments of the skin, eyes, and hair follicles. The enzyme is encoded by tyrosinase gene (TYR) or oculocutaneous albinism type 1A (OCA1A). Mutations in TYR gene result in pigmentation disorders such as albinism in humans. In view of the large number of mutations reported in this gene, the aim of this study was to id...

Tumour markers are substances that are produced either by the tumour itself or by the body in response to the presence of cancer or certain benign conditions that can aid in the diagnosis of cancer. The subject of tumour markers is a broad one, and there is an abundance of data. A literature review of potential molecular markers relevant to oral neoplasia was undertaken in terms of a perspectiv...

Many image-guidance surgical systems rely on rigid-body, point-based registration of fiducial markers attached to the patient. Marker locations in image space and physical space are used to provide the transformation that maps a point from one space to the other. Target registration error (TRE) is known to depend on the fiducial localization error (FLE), and the fiducial registration error (FRE...

background: inhibin is a dimeric glycoprotein that has a depressive effect on the anterior hypophyse secretion. the level of this tumor marker is undetectable in menopause women. in patients with gynecological cancer, especially granulosa and epidermal-type (mucinous), ovarian cancers considerable increase in the serum level of inhibin has been reported. the increased level of inhibin has been ...

malaria is currently one of the most important causes of mortality in developing countries. high resistance to available antimalarial drugs has been reported frequently, thus it is crucial to focus on the discovery of new antimalarial drugs. artemisinin, an effective antimalarial medication, is isolated from various artemisia species. to identify the artemisia species producing high quantity of...

a greenhouse experiment was conducted in 2013 in research lab of karaj islamic azad university to determine the yield and activity of chemical markers as the response to different concentrations of cadmium (cd) (0, 5, 10 and 20 mg of cd/kg of soil) in wheat cultivars (karaj 1 and karaj 2). treatments were tested in a factorial experiment with four replications in 7.5 kg plastic pots. the respon...

Recent pre-clinical and clinical studies have revealed the C-reactive protein gene (CRP) is related to the degree of acute rise in plasma C-reactive protein (CRP) levels. Moreover, single nucleotide polymorphisms (SNPs) in the CRP gene could associate with increased risk of cancer, atherosclerosis, diabetes mellitus, bowel disease, rheumatoid arthritis, psoriasis, obstructive pulmonary disease,...

objective: to evaluate whether systemic inflammatory markers (neutrophil to lymphocyte ratio (nlr), platelet to lymphocyte ratio (plr) and red blood cell distribution width (rdw) to platelet ratio (rpr)) can be used as reliable markers for the diagnosis of premature ovarian insufficiency (poi) and to determine if there is a relationship between these markers and follicle stimulating hormone (fs...

background: the availability of testis specific genes will be of help in choosing the most promising biomarkers for the detection of testicular sperm retrieval in patients with non-obstructive azoospermia (noa). testis specific chromodomain protein y 1 (cdy1) is a histone acetyltransferase which concentrates in the round spermatid nucleus, where histone hyperacetylation occurs and causes the re...
