Fish Sperm Assessment Using Software and Cooling Devices

Carina Caldeira¹, Carles Soler^1,2

¹PROiSER R+D S.L., ²Department of Cellular Biology, Functional Biology and Physical Anthropology, University of Valencia

The present protocol describes a procedure of fish sperm assessment using computer-assisted sperm analysis and cooling devices. The software gives a rapid, accurate and quantitative analysis of fish sperm quality based on spermatozoa motility, which can be a useful tool in aquaculture to improve reproduction success.

The protocol focuses on the collection of sea turtle samples, describing all the steps from the animal recovery and necropsy to the classification and quantification of ingested marine litter. Moreover, the representative results show how to use the collected data to elaborate the possible thresholds for Good Environmental Status.

Optimal Fixation Position of Deep Brain Stimulation Electrodes for Parkinson's Disease in Humans

Alfredo Rosado-Muñoz¹, Juan F. Guerrero-Martinez¹, Luciano Schiaffino², Manuel Bataller-Mompeán¹, Antonio Gutiérrez³

¹Group for Digital Design and Processing (GDDP), ETSE, Department of Electronic Engineering, University of Valencia, ²Laboratory of Rehabilitation Engineering, National University of Entre Ríos, ³Functional Neurosurgery Unit, La Fe Hospital

The fixation of deep brain stimulation microelectrodes for Parkinson’s disease requires brain surgery. This work describes a method to determine the optimal position of the stimulation electrodes during surgery, which requires a combination of techniques.
