Wooden objects are often used as nonhuman primate enrichment to provide variety and novelty, promote exploratory behavior, and supply an outlet for curiosity. However, concerns have been raised regarding the ability to sanitize wood by using conventional cage-wash procedures. To address this concern, we examined sanitation outcomes between soiled plastic toys and manzanita wooden manipulanda immediately after a cage-wash cycle. Both an ATP luminometer device, which is capable of providing an immediate assessment of sanitation levels, and traditional bacterial culture were used, with the secondary goal of comparing these methods for sanitation monitoring. Results showed that the wooden objects did not differ from plastic toys with respect to the overall efficacy of cage-wash sanitization. Therefore, manzanita wood can be used as nonhuman primate enrichment without risking pathogen transmission when items are rotated among animals. (+info)Water-extractable magnesium, manganese and copper in leaves and herbs of medicinal plants. (4/4)
Since herbal teas, infusions and decoctions prepared from medicinal plants are popular remedies, it remains a topical question whether these herbal drugs can be treated as sources of essential elements for humans, who often use them in their everyday diet. Therefore, total and water-extractable contents of Mg, Mn and Cu were determined in 41 leaves originating from four botanical species of Plantago lanceolata, Arctostaphyllos uva-ursi, Rubus fruticosus and Betula sp., as well as in 33 samples of herbs represented by three species of Urtica dioica, Hypericum perforatum and Achillea millefolium. The highest level was determined in the case of Mg (in a range from 2.0 to 7.0 mg/g of dry mass [d.m.]), followed by Mn (from 50.0 to 1300.0 mg/kg d.m.), and lowest of all, Cu (from 3.5 to 19.5 mg/kg d.m.). Student's t-test showed that a statistically significant difference exists between samples originating from different plant species regarding the total content and water-extractable forms of Mg, Mn and Cu. By analysis of the relations between elements, it was observed that total level of Cu correlated with total levels of Mg and Mn, which indicates a synergistic interaction between the essential elements under study. With regard to Dietary Reference Intakes (DRIs), the leaves of Rubus fruticosus contained the highest amounts of a water-extractable bioavailable form of Mn, which guarantees from 160 to 200% of the daily requirement of Mn for women and men, respectively. On the other hand, the extract obtained from Urticae folium gave water-extractable Mg in the amount of 76 mg/500 mL, which constitutes about 20% of daily requirement. The plant material richest in water-extractable Cu was Hyperici herba, containing 154.5 microg/500 mL, or 17% of DRI for both sexes. (+info)'Arctostaphylos' is a genus of plants in the family Ericaceae, commonly known as manzanitas. These are evergreen shrubs or small trees native to western North America, with thick, reddish bark and stiff, twisting branches. The leaves are simple, alternately arranged, and have smooth margins. The flowers are bell-shaped, white to pink, and produce a small fruit known as a drupe.
While 'Arctostaphylos' is not a medical term itself, some species of this genus have been used in traditional medicine for various purposes, such as treating wounds, skin irritations, and urinary tract infections. However, it is important to note that the use of these plants should be done under the guidance of a healthcare professional, as they can also have potential side effects or interact with other medications.
"Vaccinium vitis-idaea" is the scientific name for a species of shrub that produces edible berries known as lingonberries or cowberries. While the plant itself is not a medical term, its berries have been used in traditional medicine for their potential health benefits. However, it's important to note that these benefits have not been extensively studied and are not widely recognized in modern medicine.
The berries of Vaccinium vitis-idaea contain various compounds such as polyphenols, anthocyanins, and vitamin C, which may have antioxidant properties. Some studies suggest that consuming these berries may help protect against oxidative stress, inflammation, and certain chronic diseases. However, more research is needed to confirm these potential health benefits and establish recommended dosages.
Therefore, while Vaccinium vitis-idaea has been used in traditional medicine, it does not have a specific medical definition as a treatment or cure for any disease or condition.
"Vaccinium myrtillus" is the scientific name for a plant species, commonly known as the European blueberry or bilberry. It's a small shrub that bears blue-purple colored berries. While it is not a medical term itself, extracts from its fruits and leaves have been used in various traditional medicine systems and are also being studied in modern science for their potential health benefits. Bilberries contain various compounds including anthocyanins, which have antioxidant properties. However, it's important to note that these studies are still ongoing and not all claims are supported by robust scientific evidence.
