Publishes New Reviews of Aurora Borealis, Bayam and Uterus Didelphys

Share Article

The geographical and health sciences website publishes insights into specific subjects of all areas of geographical and health science. The latest reviews cover Aurora borealis which are the Northern Lights caused by radiation emitted as light from atoms in the upper atmosphere as they are hit by fast-moving electrons and protons, and bayam which is amaranth, a herb with approximately 60 species and inflorescences and foliage ranging from purple to red and gold. The latest insight into Uterus didelphys is about a uterine malformation where the uterus is present as a paired organ as the embryogenetic fusion of the mullerian ducts failed to occur.

The geographical and health sciences website publishes insights into all areas of geographical and health sciences including biology, agriculture, horticulture, forestry, geography, environment and health. Drawing from this pool of scientific disciplines, it publishes articles, reviews and insights on geographical and health sciences topics including those which have recently attained attention. While the Geographical and Health Sciences Research Category contains over 36 million references, most of the reviews are included in the Geographical and Health Sciences Keyword Category, the Geographical and Health Sciences Keyphrase Category and in the Geographical and Health Sciences Reviews Category of the online science magazine. The Geographical and Health Sciences Subjects Category contains links to the most recently published reviews and insights. All content is now available on a user-friendly and fast Mobile Website.

The review of Aurora Borealis covers the Northern Lights surrounding the north magnetic pole. They occur when highly charged electrons from the solar wind interact with elements in the earth's atmosphere. Solar winds stream away from the sun at speeds of about one million miles per hour. When they reach the earth, some forty hours after leaving the sun, they follow the lines of magnetic force generated by the earth's core and flow through the magnetosphere, an area of highly charged electrical and magnetic fields. As the electrons enter the earth's upper atmosphere, they will encounter atoms of oxygen and nitrogen at altitudes from twenty to two-hundred miles above the earth's surface. The color of the aurora depends on which atom is struck, and the altitude of the meeting. The review covers Aurora Borealis in the context of promoting tourism in the Northwest Territories (NWT) of Canada. Currently NWT's tourism industry is almost entirely based on its natural attractions including the Northern lights, with tourism operations focusing on ecotourism and adventure tourism. Seasonal problems with land transport infrastructure, a failure to promote cultural and heritage attractions in the region, the exclusive use of English for marketing and promotional activities, a lack of an appropriately trained and skilled workforce, and the absence of targeted marketing plans hinder the development of tourism in the NWT.

The review of Bayam covers amaranth, which is a genus of herbs. Approximately 60 species of Bayam are recognized, with inflorescences and foliage ranging from purple and red to gold. Although several species are very significant weeds in tropical agriculture, bayam can be used as a leafy vegetables, as a cereal, and as an ornamental. The review demonstrates that five types of "bayam" namely 'bayam putih', 'bayam merah', 'bayam itik', 'bayam duri', 'bayam ekor kucing' can be found in Malaysia and that urban and rural communities most commonly consume 'bayam putih' and 'bayam merah'. Bayam species have high antioxidant capacity among other vegetables. Besides other antioxidant components, bayam is also a good source of phenolic compounds. These compounds are able to act as a potent antioxidant component. The green leafy vegetable is cooked before being consumed. Cooking practices affect the antioxidant capacity and phenolic content in bayam. Major losses of antioxidant capacity and phenolic content of the fresh bayam are usually observed after cooking for more than ten minutes. The consumption of leafy green vegetables including bayam is important to promote a high intake of antioxidant components. presents a scientific review of Uterus Didelphys covering a uterine malformation where the uterus is present as a paired organ as the embryogenetic fusion of the mullerian ducts failed to occur. As a result there is a double uterus with two separate cervices, and often a double vagina as well. Each uterus has a single horn linked to the ipsilateral fallopian tube that faces its ovary. The review presents an introduction of the Uterus Didelphys syndrome with radiological and especially magnetic resonance (MR) imaging findings. The authors reviewed imaging findings and medical records of seven patients with this syndrome. In this study, MR clearly demonstrated uterus didelphys with obstructed hemivagina in six of the seven patients studied. Another patient showed uterus didelphys with left-sided hematometra and hematosalpinx who had undergone vaginal septum incision prior to the MR. The authors were able to recognize ipsilateral renal agenesis in five patients, in whom renal areas were examined on MR. After vaginal septum resection, symptoms disappeared in six patients and the authors could observe the disappearance of the obstructive complications with MR in three patients. Initially, the anomaly remains unrecognized, while patients most frequently referred to surgeons for assistance. The method of choice for diagnosis is magnetic resonance imaging. A greater awareness of the syndrome of uterus didelphys, obstructed hemivagina and ipsilateral renal agenesis should lead to its prompt diagnosis, allowing for early and appropriate surgical treatment as well as decreased long-term morbidity. Hysteroscopic surgery to correct uterine septa, intrauterine synechiae, and myomas that distort the uterine cavity may benefit women with infertility or recurrent pregnancy loss. The effect of endometrial polyps on fertility, is uncertain, but their removal, once identified, is justifiable.

The Science Magazine was launched in November 1998 as the online version of the French science magazine "Eurêka - Le magazine des sciences" published since 1995. During the past decade, it has emerged as a comprehensive aggregator of information on biology, on the applied life sciences agriculture, horticulture and forestry, on the earth sciences, on the environmental sciences, and on the health sciences.
