Comprehensive annotated checklist of monogenean diversity and distribution in Algerian marine fish.

A comprehensive checklist of monogenean parasites from marine fish in Algeria was compiled by reviewing the entire available literature, resulting in a detailed parasite-host and host-parasite list. This checklist includes 156 species across 71 genera and 23 families of monogeneans, with 136 species identified to the species level, while the remaining 20 species are identified only to the genus (19 species) or subfamily level (1 species). These parasites have been reported from 82 marine fish hosts, spanning 34 families: 15 species of Elasmobranchii, 1 of Holocephali, and 66 of Teleostei.

Digenea community structure of the Salema, (Linnaeus, 1758) (Teleostei, Sparidae), from the Central coast of Algeria.

The main goal of the current work was to describe and analyse the Digenean community structure in A total of 114 specimens of were collected from the Central Coast of Algeria at six localities. The fish were immediately transported to the laboratory to be examined for digeneans. From 107 of the 114 examined, a total of 8,722 specimens of seven species belonging to three families were recovered.

A comparative study of the quantification of REM occurrence patterns via REM density and REM time-connectivity.

In a previous study, we have shown that the use of a Markovian model and its associated state-transition probability matrices (STPMs) is a viable non-invasive approach to quantify the dynamics of REM occurrence patterns. This paper describes an attempt to compress the information conveyed by the STPMs into one single scalar parameter, defined as the time-connectivity of inter-REM intervals. This parameter was studied in conjunction with REM density, another global index of phasic REM activity during sleep, and the two were compared in terms of their variability with respect to subject, night of sleep recording and REM period rank in six healthy young subjects.

Non-random patterns of REM occurrences during REM sleep in normal human subjects: an automated second-order study using Markovian modeling.

An automated analysis of the patterns in REM occurrences during REM sleep in 6 healthy young adults was performed, with an emphasis on second-order parameters. It was found that the majority of REMs were grouped in bursts with a tendency to return to the burst mode once outside of it. The occurrence pattern of REMs within bursts was found not to be of a purely random (renewal) nature, in distinction to that of isolated REMs.
