This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Malignant renal cell carcinoma accounts for approximately 2% of cancer cases worldwide, and kidney renal clear cell carcinoma (KIRC) is the most common subtype. Tumor angiogenesis is an important prognostic indicator and therapeutic target for KIRC. However, the specific angiogenesis subtypes in KIRC and their epigenetic regulation mechanisms are not well defined. In a recent multi-omics study, researchers analyzed these subtypes in patients using published molecular datasets. Angiogenesis scores calculated based on a 189-gene molecular signature were correlated with several prognostic indicators in over 500 patients. The five genes that contributed most to the scores (MMRN2, CLEC14A, ACVRL1, EFNB2, and TEK) were also associated with overall survival. Clustering analysis based on 183 of the signature genes identified two angiogenesis subtypes among the patients..."

An interactive applet and associated web page that introduce the concept of an angle. An angle made from two line segments is shown that the user can adjust by dragging the end points of the segments. In real time, as the angles is changed by the user, the angle measure in degrees is shown and a message telling what type of angle it currently is: acute, right, obtuse, reflex or straight. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that demonstrate the bisector of an angle. An angle is shown using two line segments that can be dragged to change the angle measure. The angle is bisected by a line which moves while dragging to always divide the angle into two equal angles. The angle measures can be turned off for class discussions. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet that acts as a 'digital manipulative' for explaining angles measured in degrees. The applet has an angle formed from two segment that can be dragged around in a circle. The angle measure is shown against a 'clock face' calibrated in degrees. The measures can be turned off for class angle estimation discussions. Applet can be enlarged to full screen size for use with a classroom projector.

In plane geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.[1] Angles formed by two rays lie in a plane, but this plane does not have to be a Euclidean plane. Angles are also formed by the intersection of two planes in Euclidean and other spaces. These are called dihedral angles

Animals are an important part of the ecosystem. They help to maintain the balance of nature by providing food for other animals, by pollinating plants, and by dispersing seeds. Animals are also important to humans, as they provide us with food, clothing, and companionship.However, animals are facing a number of threats, including habitat loss, climate change, and pollution. These threats are causing the decline of many animal species, and some species are even facing extinction.It is important to conserve animals and to protect their habitats so that future generations can enjoy them.

Hibernation is an ingenious adaptation that some animals employ to survive difficult conditions in winter. This unit examines the differences between hibernation and torpor, and discusses the characteristic signs of hibernation behavior It explores the triggers that bring on hibernation, and whether internal signals or external season cues are predominant. It also examines the physiological adaptations that occur in hibernating animals.
