Somatic Embryogenesis from Immature Olive Zygotic Embryos.

The effects of plant growth regulators (PGRs) and the explant type on the embryogenesis and plant regeneration of olive (Olea europaea L. ssp europaea var. sativa) cv.

Association between isokinetic abdominal muscle strength, pelvic floor muscle strength and stress urinary incontinence severity.

Objectives: Studies have shown that there is co-activation between abdominal and pelvic floor muscles (PFM) in physiological conditions. This study aimed to assess pelvic floor and isokinetic trunk flexors function in non-active incontinent women, and to investigate the association between the strength of these muscle groups and the severity of stress urinary incontinence (SUI).

Methods: A cross-sectional study was carried out.

Intravitreal air bubbles following intravitreal injections: a comprehensive analysis.

Purpose: To evaluate the prevalence of residual air bubbles following intravitreal injections of anti-VEGF agents, and to compare two techniques designed to reduce their occurrence.

Methods: Patients who received intravitreal injections reported the presence of air bubbles following the procedure, and were followed to determine when they disappeared. Two techniques used to reduce air bubbles prior to injection were compared-tapping the syringe with the needle up ("upwards" technique) or down ("downwards" technique).

Impact of the COVID-19 Pandemic on Orthopedic and Trauma Departments in Tunisia.

Objective: Measure the effect of the strategy to fight the Covid-19 pandemic, based on containment, on the practice of orthopedic and trauma surgery in Tunisia.

Methods: This is a comparative study, concerning the impact of Covid-19 on the flow of patients, operated in orthopedic surgery and trauma departments, during the containment period from March 12, 2020 to April 30, 2020, comparing it to the same period of the year 2019, in the Central-East region of Tunisia (Kairouan, Sousse, Mahdia, Monastir).

Results: A significant decrease of 27% in the flow of patients admitted to orthopedic surgery departments in central-eastern Tunisia, during the 2020 containment period, compared to the same period of the previous year was documented.

Isolation, Characterization and Chemical Synthesis of Large Spectrum Antimicrobial Cyclic Dipeptide (l-leu-l-pro) from V16R3Y1 Bacteria Extracts. A Novel H NMR Metabolomic Approach.

Streptomyces is the most frequently described genus of Actinomycetes, a producer of biologically active secondary metabolites. Indeed, the Streptomyces species produces about 70% of antibiotics and 60% of antifungal molecules used in agriculture. Our study was carried out with the goal of isolating and identifying antimicrobial secondary metabolites from V16R3Y1 isolated from the date palm rhizosphere (southern Tunisia).

Occurrence of diarrhetic shellfish poisoning (DSP) toxins in clams (Ruditapes decussatus) from Tunis north lagoon.

The main diarrhetic shellfish toxins, okadaic acid (OA) and dinophysistoxin-1, 2 (DTX-2, 2) were detected by liquid chromatography-tandem mass spectrometry (LC-MS/MS) as pyrenacyl esters in clams (Ruditapes decussatus) collected in Tunis north lagoon from January 2007 to June 2008. Sample analyses by LC-MS/MS displayed OA and related congeners (DTX-2, 2) with a highest detected level of 21 μg OA eq/kg shellfish meat for the samples of January 2007. Nevertheless, all samples were MBA negative.

First recorded proliferation of Coolia monotis (Meunier, 1919) in the North Lake of Tunis (Tunisia) correlation with environmental factors.

Coolia monotis is a potentially toxic epiphytic dinoflagellate widespread along the Mediterranean coasts, where it is frequently detected year round at low concentrations. However, it only proliferates recurrently in some localities. The North Lake of Tunis is one of the affected areas in the southwestern part of the Mediterranean Sea.
