1. Evolutionary and Pharmacological Studies of NPY and QRFP Receptors
Abstract : The neuropeptide Y (NPY) system consists of 3-4 peptides and 4-7 receptors in vertebrates. It has powerful effects on appetite regulation and is involved in many other biological processes including blood pressure regulation, bone formation and anxiety. READ MORE

2. Sperm Membrane Channels, Receptors and Kinematics : Using boar spermatozoa for drug toxicity screening
Abstract : 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. READ MORE

3. The influence of lysozyme and oligothiophenes on amyloid-β toxicity in models of Alzheimer’s disease
Abstract : Alzheimer’s disease (AD) is a neurodegenerative disease and the most common cause of dementia worldwide. Apart from dominantly inherited mutations, age is the major risk factor and as life expectancy increases the prevalence for AD escalates dramatically. READ MORE

4. Towards improved drinking water safety : the use of in vitro bioassays to optimize treatment processes and assess chemical hazards
Abstract : Drinking water safety has been primarily dependent on the monitoring of only a limited number of individual chemicals via chemical analysis, which is insufficient to characterize the myriad of hazardous chemicals present in water. Effect-based methods (EBMs) using in vitro bioassays are useful in that they evaluate biological effects from all the known and unknown chemicals in the water and draw on toxicological principles.

5. Exposure to xenobiotic chemicals disrupts metabolism, rhythmicity and cell proliferation in Drosophila melanogaster
Abstract : Most species are constantly exposed to xenobiotic chemicals through multiple routes. Among all categories of xenobiotics, phthalates and bisphenols are two of the most widely used plasticizers and can be found in polyvinyl chloride (PVC) materials, medical devices and even drinking water.
