Among living plants, this type of stele is found only in the stems of ferns. Most seed plant stems possess a vascular arrangement which has been interpreted as a derived siphonostele, and is called a eustele – in this arrangement, the primary vascular tissue consists of vascular bundles, usually in one or two rings around the pith. [12]
The endodermis is the boundary between the cortex and the stele. In many seedless plants, such as ferns, the endodermis is a distinct layer of cells immediately outside the vascular cylinder (stele) in roots and shoots. In most seed plants, especially woody types, the endodermis is present in roots but not in stems.
Mortality and adverse cardiovascular events were reduced in statin groups. [42] Older adults who receive statin therapy at time of discharge from the hospital after an inpatient stay have been studied. People with cardiac ischemia not previously on statins at the time of admission have a lower risk of major cardiac adverse events and hospital ...
Statins have sometimes been grouped into two groups of statins according to their structure. [9] Type 1 statins Statins that have substituted decalin-ring structure that resemble the first statin ever discovered, mevastatin have often been classified as type 1 statins due to their structural relationship. Statins that belong to this group are: [9]
Statin-associated autoimmune myopathy (SAAM), also known as anti-HMGCR myopathy, is a very rare form of muscle damage caused by the immune system in people who take statin medications. [1] However, there are cases of SAAM in patients who have not taken statin medication, and this can be explained by the exposure to natural sources of statin ...
The last stele erected in Axum was probably the so-called King Ezana's Stele, in the 4th century CE. King Ezana (c. 321 – c. 360), influenced by his childhood tutor Frumentius , introduced Christianity to Axum, precluding the pagan practice of erecting burial stelae (it seems that at the feet of each obelisk, together with the grave, there ...
Cholesterol is the principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils. [3] [4]Cholesterol is biosynthesized by all animal cells [citation needed] and is an essential structural and signaling component of animal cell membranes.
The Tel Dan Stele is a fragmentary stele containing an Aramaic inscription which dates to the 9th century BCE. It is the earliest known extra-biblical archaeological reference to the house of David. [1] [2] The stele was discovered in 1993 in Tel-Dan by Gila Cook, a member of an archaeological team led by Avraham Biran.
