Aims
The study aimed for evaluate the efficacy of Pseudomonas knackmussiiMLR6 on growth promotion, photosynthetic responses, pigment contents and gene expression of the plant model Arabidopsis ...thaliana under NaCl stress.
Methods and Results
The strain MLR6 was isolated from the rhizopshere of the halophyte Salsola tetrandra collected from a natural saline Algerian soil. Results showed the ability of MLR6 to induce plant growth‐promoting traits even under NaCl stress. The inoculation with MLR6 improved the stomatal conductance, the transpiration rate, the total chlorophyll and carotenoid contents under salt stress. It conferred also an increase in fresh/dry weight as well as plant height. MLR6 inoculation further provided a positive effect on cell membrane stability by reducing the electrolyte leakage and priming the ROS accumulation after the salt exposition. Additionally, the expression of NHX1, HKT1, SOS2 and SOS3 as well as SAG13 and PR1 was maintained in MLR6‐bacterized plant at a similar level of controls.
Conclusions
The inoculation of A. thaliana with MLR6 improves plant growth and reduces damages caused by salt stress.
Significance and Impact of the Study
The use of P. knackmussiiMLR6 appears as a promising strategy to improve the sustainable agriculture under saline conditions.

In order to cope with the occupancy and radiation doses expected at the High-Luminosity LHC, the ATLAS experiment will replace its Inner Detector with an all-silicon Inner Tracker (ITk), consisting ...of pixel and strip subsystems.
In the last two years, several prototype ITk strip modules have been tested using beams of high energy electrons produced at the DESY-II testbeam facility. Tracking was provided by EUDET telescopes. The modules tested are built from two sensor types: the rectangular ATLAS17LS, which will be used in the outer layers of the central barrel region of the detector, and the annular ATLAS12EC, which will be used in the innermost ring (R0) of the forward region. Additionally, a structure with two R0 modules positioned back-to-back has been measured, demonstrating space point reconstruction using the stereo angle of the strips. Finally, one barrel and one R0 module have been measured after irradiation to 40% beyond the expected end-of-lifetime fluence. The data obtained allow for thorough tests of the module performance, including charge collection, noise occupancy, detection efficiency, and tracking performance. The results give confidence that the ITk strip detector will meet the requirements of the ATLAS experiment.

À la suite de l’arrivée de la fièvre catarrhale ovine (FCO) en Tunisie, les auteurs rapportent les résultats de la première enquête effectuée dans le Gouvernorat de Monastir. Ils signalent la ...présence de neuf espèces de Culicoides dont trois sont nouvelles pour le pays (C. paolae, C. imicola, C. newsteadi), ce qui porte à 22 le nombre d’espèces actuellement connues.
Following the arrival of blue-tongue in Tunisia, the authors report the results of the first survey made in Monastir. They show the existence of nine species of Culicoides, three of which are new to the country (C. paolae, C. imicola, C. newsteadi), that now brings to 22 the number of the known species.
Une maladie cœliaque de l’adulte révélée par une crise cœliaque associée à une tétraplégie due à une hypokaliémie de déplétion est une situation clinique très rare.
Il s’agit d’une jeune femme de ...26 ans, hospitalisée pour une paralysie des quatre membres dans un contexte de diarrhée profuse. Les auteurs mettent l’accent sur l’éventualité d’un tableau inaugural brutal de la maladie cœliaque de l’adulte, appelé crise cœliaque et caractérisé par une diarrhée sévère, source de complications métaboliques menaçant le pronostic vital, et responsable, dans le cas décrit, d’une tétraplégie hypokaliémique. La diarrhée et le déficit neurologique ont répondu favorablement au régime sans gluten et à la supplémentation potassique.
Une crise cœliaque, caractérisée par une diarrhée brutale de l’adulte avec des complications métaboliques et systémiques majeures, peut être le mode de révélation d’une maladie cœliaque de l’adulte jusque là asymptomatique ou pauci symptomatique.
Adult cœliac disease revealed by cœliac crisis and quadriplegia due to potassium depletion is an extremely rare situation.
A 26-year-old woman presented with a suddenly developed weakness of all four limbs and a severe diarrhea. Authors emphasize cœliac crisis, which is a presenting feature of cœliac disease, characterized by acute diarrhea with life-threatening acid base and electrolyte abnormalities. The patient improved with correction of hypokalemia and gluten-free diet.
A severe acute diarrhea with metabolic and systemic complications, the so-called cœliac crisis, is a possible presenting clinical feature of a previously undiagnosed adult celiac disease.

A patient had five relapses of polyneuropathy: four developed during post-partum. The rapid onset of symptoms with subsequent complete recovery are in favor of a recurrent Guillain-Barré syndrome ...rather than a chronic relapsing inflammatory polyneuropathy.
