Antibacterial, Cytotoxic and Genotoxic Assessment of New Sulfonamide Derivatives.

In the last few years, the interest in sulfonamides has expanded owing to their broad spectrum of biological activities. Their flexible structure turns them into amazing candidates to replace old drugs or develop modern multi-target agents. In this study, a series of new sulfonamides (sul1-5) was evaluated, in vitro, for the antibacterial, cytotoxic and genotoxic effects.

On the occurrence of Branchinecta orientalis Sars, 1901 (Crustacea, Anostraca) in Algeria, with some ecological notes.

The first substantiated record of Branchinecta orientalis in Algeria is here reported. This species was found in a small freshwater pool (Jemot) in Oum El Bouaghi province, located in the High Plateaus of the Aurès region in North-East of Algeria. Details on biogeography, ecology and morphology of this Algerian population of the species are provided.

Living ostracods (Crustacea) from Algerian Sahara and High Plains: ecological data and new records.

Between 2017 and 2018, in order to complete the list of the Algerian freshwater ostracods, 62 water bodies were sampled across the Sahara and the semi-arid High Plains. The physico-chemical parameters (salinity, temperature and pH) were measured, and the coordinates of the sites, their surface area and altitude were also recorded. A total of 24 ostracod species were identified, belonging to 4 different families (Darwinulidae, Ilyocyprididae, Cyprididae and Cytherideidae).

Chirocephalus sanhadjaensis sp. nov., a new chirocephalid species (Branchiopoda: Anostraca) from Numidia (Algeria).

A new species of Chirocephalus collected in temporary freshwater ponds in Northeastern Algeria is described. Chirocephalus sanhadjaensis sp. nov.

An annotated checklist of the Algerian Cladocera (Crustacea: Branchiopoda).

We present an annotated checklist of the Cladocera (orders Ctenopoda and Anomopoda) from the continental waters of Algeria, based on published records and original data from analysis of samples from 112 water bodies collected in 2012-2016 in humid and semi-arid regions of the country. Thirty six species have been identified in this study. Three taxa (Daphnia obtusa, D.
