In order to further investigate the radical scavenging and anti-arteriosclerotic activities of vitamin K2 and estradiol, the comparative effects of vitamin K2 and estradiol on aortic calcium (Ca) and inorganic phosphorus (P) levels in the aorta and the elastin fraction (fr.) were investigated in male rats after experimental arteriosclerosis with diabetes mellitus was induced by vitamin D2 and r...

The high-temperature/high-pressure treatment of the K-Te-U oxo-family at 1100 °C and 3.5 GPa results in the crystallization of a series of novel uranyl tellurium compounds, K2[(UO2)3(TeIVO3)4], K2[(UO2)TeO14], α-K2[(UO2)TeVIO5] and β-K2[(UO2)TeVIO5]. In contrast to most of the reported uranyl compounds which are favorable in layered structures, we found that under extreme conditions, the potass...

Introduction Vitamin K is a fat-soluble vitamin essential for the functioning of several proteins involved in blood clotting.1 Discovered in 1929 by Danish scientist Henrik Dam, the vitamin received the letter “K” because the initial discoveries were reported in a German journal in which the substance was designated as “Koagulationsvitamin.” Research during the last 30 years has resulted in gre...

2. Definition of the join (Ki, K2) of Ki and K2. To define the join of two complexes we first define the join (o-, r) of a ^-dimensional simplex a and a g-dimensional simplex r, p, <7 = 0, 1, • • • . This join is a (£+<Z + l)-dimensional simplex with a ^-dimensional side associated with a and the opposite side, which is ^-dimensional, associated with r. These sides will not be distinguished fro...

Hydrologic modeling of semi-arid watersheds is imperative for the development of appropriate water and soil conservation plans. In the current study, the efficiency of Kinematic Runoff and Erosion model-version 2 (K2) model was used to evaluate water discharge and sediment load simulation of Bar watershed, located in the north-eastern part of Iran. The K2 model relies on the kinematic wave appr...

“K2-spice” is a term representing a new group of designer drugs that contain synthetic cannabinoids, which are incorporated into herbal products. These synthetic cannabinoids bind the same receptors as tetrahydrocannabinol (THC), the active ingredient in marijuana, but with greater affinity. Unfortunately, people that intentionally abuse K2-spice experience clinical signs that are more adverse ...
