The Miracle in The Cell Membrane By Harun Yahya
eBook (PDF): $3.20
(1 Ratings)
The 100 trillion or so cells that make up the human body perform countless activities, without ever stopping, growing tired or needing a rest. In the same way that every living thing needs... More > energy—and therefore, food—to survive, so the cell also needs various nutrients in order to perform its countless functions. In the same way that raw materials to be used in production are carried inside a factory and stored until needed, and waste products are later sent out of the factory later, so a very complex production, storage and waste-disposal system operates within the cell.< Less

Membrane Lipid Signaling In Aging and Age-related Disease By Mark P. Mattson
eBook (PDF): $9.99
The lipids that comprise membranes of cells, be they phospholipids, sphingolipids, glycolipids or even cholesterol, serve many functions beyond their role in the structural organization of the... More > membranes. In response to stimulation by various agonists, and environmental insults such as oxidative stress, several different membrane lipids are cleaved either enzymatically or non-enzymatically. Products are thereby released that act as important signals mediating physiological responses to the stimuli. Among the most intensively studied signaling pathways is the inositol phospholipid signaling, which leads to the production of IP3 and diacylglycerol with consequent calcium release and protein kinase activation. Another example of a prominent signaling pathway involves sphingomyelin hydrolysis resulting in the production of ceramide, which acts as an important signal in both physiological and pathophysiological settings.< Less

Misura elettrochimica della permeabilità dello iodio attraverso membrane polimeriche. By Alfonso Pozio
eBook (PDF): $6.52
Scopo del presente lavoro è quello di verificare il grado di permeabilità di membrane di Nafion 1100 da utilizzare come elettrolita polimerico solido in celle a combustibile I2/H2. In... More > particolare è stata analizzato il comportamento di una membrana di Nafion posta a contatto di una soluzione concentrata di acido iodirico e satura di iodio. E’stato ricavato l’indice di permeabilità di tale membrana, l’influenza della permeazione sul potenziale anodico e la resistenza della membrana nelle condizioni ipotizzate in una cella reale.< Less
A Peek At the Acme of God’s Creation By Daniel Zimmermann
eBook (ePub): $1.99
God deserves the credit that the title of this article expresses. He not only created the human body, but He certainly must have helped me when I wrote these articles. The explanations are... More > exceptionally lucid, so much so that I myself am amazed as I proofread them. The first section studies a few bones of the body: the bones of the cranium, the bones of the hands and wrist, and the bones of the foot, with a special article on the calcaneus. The second section contains a single article: “A Journey through a Nephron.” The third section studies a few important physiological substances: hormones, lipids, amino acids, and hyaline cartilage. The fourth section studies a few cellular phenomena. The final section contains a single article entitled “A Hypothesis on the Formation of Junk DNA.” Admittedly, I cannot appeal to any authority, either religious or scientific, to support this hypothesis. It is my own brainchild, born of mature reflection. Moreover, it cannot be proved or disproved.< Less

Cholesterol is a lipidic (fatty), waxy alcohol found in the cell membranes and transported in the blood plasma of all animals. It is an essential component of mammalian cell membranes where it is... More > required to establish proper membrane permeability and fluidity. Cholesterol is the principal sterol synthesized by animals, but small quantities are synthesized in other eukaryotes, such as plants and fungi. It is almost completely absent among prokaryotes, which include bacteria. Cholesterol is classified as a sterol (a contraction of steroid and alcohol).< Less
