https://en.wikipedia.org/wiki/Rectoprostatic%20fascia | The rectoprostatic fascia (Denonvilliers' fascia) is a membranous partition at the lowest part of the rectovesical pouch. It separates the prostate and urinary bladder from the rectum. It consists of a single fibromuscular structure with several layers that are fused together and covering the seminal vesicles. It is al... |
https://en.wikipedia.org/wiki/Israeli%20Cassini%20Soldner | Israeli Cassini Soldner (ICS), commonly known as the Old Israeli Grid (OIG; Reshet Yisra'el Ha-Yeshana) is the old geographic coordinate system for Israel. The name is derived from the Cassini Soldner projection it uses and the fact that it is optimized for Israel. ICS has been mostly replaced by the new coordinate sy... |
https://en.wikipedia.org/wiki/Monadic%20second-order%20logic | In mathematical logic, monadic second-order logic (MSO) is the fragment of second-order logic where the second-order quantification is limited to quantification over sets. It is particularly important in the logic of graphs, because of Courcelle's theorem, which provides algorithms for evaluating monadic second-order f... |
https://en.wikipedia.org/wiki/Spongy%20tissue | Spongy tissue is a type of tissue found both in plants and animals.
In plants, it is part of the mesophyll, where it forms a layer next to the palisade cells in the leaf. The spongy mesophyll's function is to allow for the interchange of gases () that are needed for photosynthesis. The spongy mesophyll cells are less ... |
https://en.wikipedia.org/wiki/Fibronectin%20type%20II%20domain | Fibronectin type II domain is a collagen-binding protein domain. Fibronectin is a multi-domain glycoprotein, found in a soluble form in plasma, and in an insoluble form in loose connective tissue and basement membranes, that binds cell surfaces and various compounds including collagen, fibrin, heparin, DNA, and actin.... |

GST conjugates reduced glutathione to a variety of targets including
S-crystallin from squid, the eukaryotic elongation factor
1-gamma, the HSP26 family of stress-related proteins and
auxin-regulated proteins in pl... |
https://en.wikipedia.org/wiki/Theta%20solvent | In a polymer solution, a theta solvent (or θ solvent) is a solvent in which polymer coils act like ideal chains, assuming exactly their random walk coil dimensions. Therefore, the Mark–Houwink equation exponent is in a theta solvent. Thermodynamically, the excess chemical potential of mixing between a polymer and a th... |
https://en.wikipedia.org/wiki/Tukey%27s%20range%20test | Tukey's range test, also known as Tukey's test, Tukey method, Tukey's honest significance test, or Tukey's HSD (honestly significant difference) test, is a single-step multiple comparison procedure and statistical test. It can be used to find means that are significantly different from each other.
Named after John Tu... |
https://en.wikipedia.org/wiki/Protein%20kinase%20domain | The protein kinase domain is a structurally conserved protein domain containing the catalytic function of protein kinases. Protein kinases are a group of enzymes that move a phosphate group onto proteins, in a process called phosphorylation. This functions as an on/off switch for many cellular processes, including met... |
https://en.wikipedia.org/wiki/Western%20clawed%20frog | The western clawed frog (Xenopus tropicalis) is a species of frog in the family Pipidae, also known as tropical clawed frog. It is the only species in the genus Xenopus to have a diploid genome. Its genome has been sequenced, making it a significant model organism for genetics that complements the related species Xenop... |
