Abstract Sex has a significant effect on various traits among dioecious plants. In this analysis of the sex radial growth and wood density numerous 20-year-old trees Populus deltoides growing in common garden, male performed better than females growth, but did not significantly affect density. Growth rate were weakly negatively correlated. selection is also critical for controlling seed-hair po...

 Background: Human hair can be used as an inexpensive and accessible adsorbent to remove a variety of pollutants from air. Although several studies have been done on removal of formaldehyde from wastewater by human hair, to date no study has investigated using hair to remove formaldehyde from air. Therefore, the aim of this study was to remove formaldehyde from synthetic contaminated a...

FIELD study was undertaken in 1939 by WYANDT in order to A collect human pedigrees showing oval red blood cells. The rare but non-pathological condition of elliptical erythrocytes was apparently known in medicine even before the first published account which we have been able to locate (DRESBACH 1904)~ but its hereditary nature was not well established until 1929 (HUNTER and ADAMS). CHENEY (193...

Melanoma is a malignant cancer of pigment-producing cells in our skin, exhibiting an exceptional mutational burden and drug resistance. This partly due to exposure UV radiation higher incidence genetic variations associated with fair freckles, red hair, which can lead DNA damage melanoma development. Defective apoptosis pathways constitute one barrier treatment. Thus, targeting regulators promi...

With several hundred genetic diseases and an advantageous genome structure, dogs are ideal for mapping genes that cause disease. Here we report the development of a genotyping array with B27,000 SNPs and show that genome-wide association mapping of mendelian traits in dog breeds can be achieved with only B20 dogs. Specifically, we map two traits with mendelian inheritance: the major white spott...

Introduction & Objectives: Alopecia or hair loss is defined as the loss of hair on the head or body. Despite the benign prognosis of hair loss, it has a clear impact on the quality of life of the patients who are involved. There are many reasons to explain the pathophysiology of hair loss. Among many nutritional factors, vitamin D deficiency may play a role in hair loss too. Active vitamin D or...

BACKGROUND Commercial sheep raised for mutton grow faster than traditional Chinese sheep breeds. Here, we aimed to evaluate genetic selection among three different types of sheep breed: two well-known commercial mutton breeds and one indigenous Chinese breed. RESULTS We first combined locus-specific branch lengths and di statistical methods to detect candidate regions targeted by selection in...

The synthesis of melanins, which are the most common animal pigments, is influenced by glutathione (GSH), a key intracellular antioxidant. At high GSH levels, pheomelanin (the lightest melanin form) is produced, whereas production of eumelanin (the darkest melanin form) does not require GSH. Oxidative damage typically increases with age, and age-related decreases in GSH have accordingly been fo...
