Distribution of unusual cholesterol precursors, 4-methyl- and 4, 4-dimethylsterols with δ8 unsaturation, in gonads of marine archaeogastropods.
In the present study, we show that four unusual cholesterol precursors, 5α-cholesta-8,14-dien-3β-ol, 4-methyl-5α-cholesta-8,24-dien-3β-ol (4-methylzymosterol), 4,4,14-trimethyl-5α-cholesta-8,24-dien-3β-ol (lanosterol), and 4,4-dimethyl-5α-cholesta-8,24-dien-3β-ol (4,4-dimethylzymosterol) are present in testes of the limpet Cellana grata, which is part of one of the most primitive gastropod fami...
متن کاملShell clamping behaviour in the limpet Cellana tramoserica.
The behaviour of clamping the shell against the substratum may play an important role in the limpet adhesion mechanism because friction generated by this behaviour resists dislodgement by shear forces. This paper describes the development of an apparatus to analyse limpet clamping activity in relation to known forces, including simulated wave activity and predator attack. The results show that ...
متن کاملThe value of troponin measurement in the prognosis of Covid 19 disease, a review study
Acute Respiratory Syndrome Coronavirus 2, which appeared in late 2019, can have negative effects on the cardiovascular system. Studies in different parts of the world indicate the importance of cardiac troponin as a predictor in coronary heart disease patients. Heart damage occurs frequently in Coronavirus 2 infection and is associated with a high risk of mortality in these patients. In people ...
متن کاملMetabolic energy sensors (AMPK and SIRT1), protein carbonylation and cardiac failure as biomarkers of thermal stress in an intertidal limpet: linking energetic allocation with environmental temperature during aerial emersion.
The effects of heat stress on organisms are manifested at the levels of organ function, metabolic activity, protein stability and gene expression. Here, we examined effects of high temperature on the intertidal limpet Cellana toreuma to determine how the temperatures at which (1) organ failure (cardiac function), (2) irreversible protein damage (carbonylation) and (3) expression of genes encodi...
متن کاملThe Relationship between Laboratory, Yoyo, and Hoff Tests in Determining Aerobic Capacity of Players of the National Women’s Soccer Team
Aerobic capacity bears importance in soccer. Although laboratory tests are of high credibility to measure the oxygen consumption among soccer players in laboratory conditions, field tests simulating the real need of soccer, without requiring complicated equipment, are necessary. The purpose of the present paper is to study the relationship between Hoff tests, Yoyo intermittent recovery test, ...
