1. Sperm Membrane Channels, Receptors and Kinematics : Using boar spermatozoa for drug toxicity screening
Sammanfattning : Internal fertilization usually implies that a spermatozoon, with intact attributes for zygote formation, passes all hurdles during its transport through the female genitalia and reaches the oocyte. During this journey, millions to billions of other spermatozoa perish. LÄS MER
Sammanfattning : Apoptosis, or programmed cell death, is essential for proper development and functioning of the body systems. During development, apoptosis plays a central role to sculpt the embryo, and in adults, to maintain tissue homeostasis by eliminating redundant, damaged or effete cells. Therefore, a tight regulation of this process is essential. LÄS MER
Sammanfattning : Membrane protein dynamics is of great importance for living organisms. The precise localization of proteins composing a synapse on the membrane facing a nerve terminus is essential for proper functioning of the nervous system. In muscle fibers, the nicotinic acetylcholine is densely packed under the motor nerve termini. LÄS MER
Sammanfattning : Caenorhabditis elegans PAQR-2 (a homolog of the mammalian AdipoR1 and AdipoR2 proteins) and IGLR-2 (homolog of the mammalian LRIG proteins) form a complex at the plasma membrane that regulates fatty acid desaturation to protect against saturated fatty acid-induced membrane rigidification. Maintenance of membrane homeostasis is fundamental for most cellular processes and, given its importance, robust regulatory mechanisms must exist that adjust lipid composition to compensate for dietary variation.

Sammanfattning : Desalination has been increasingly adopted over the last decades as an option, and sometimes as a necessity to overcome water shortages in many areas around the world. Today, several thermal and physical separation technologies are well established in large scale production for domestic and industrial purposes. LÄS MER
