Article Synopsis
  • This study evaluated the antioxidant and antileishmanial effects of essential oil from Ballota (B.) hirsuta leaves, identifying spathulenol and germacrene D as its main components.
  • The essential oil demonstrated moderate antioxidant activity and high antileishmanial effectiveness against both promastigote and amastigote forms of Leishmania, with specific IC values indicating its potency.
  • The study also revealed that B. hirsuta EO primarily inhibits the sterol synthesis pathway and suggested that its main compounds may be promising candidates for developing treatments against leishmaniasis.

Article Synopsis
  • * Major compounds identified in the EO included α-pinene and -cadinol, but the oil showed limited antioxidant activity, failing to neutralize certain free radicals effectively.
  • * The EO demonstrated strong leishmanicidal effects against promastigote and amastigote forms, with the components showing better binding to the enzyme CYP51 compared to the conventional drug fluconazole, suggesting it could be a promising alternative treatment for leishmaniasis.

In the realm of cancer research, specifically focusing on colorectal carcinomas (CRCs), a novel diagnostic test referred to as 'Immunoscore' (IS) has emerged. This test relies on assessing the density of tumour-infiltrating lymphocytes, specifically CD3 and CD8, in both the centre of the tumour (CT) and its invasive margin (IM). IS holds promise as a potential prognostic factor.

Beneficial microorganisms, including members of the genus, are known for their ability to promote plant growth and disease resistance, as well as being alternatives to synthetic inputs in agriculture. In this study, 111 strains were isolated from the rhizospheric soil of Florence Aurore, an ancient wheat variety that was cultivated in an organic farming system in Tunisia. A preliminary ITS analysis allowed us to cluster these 111 isolates into three main groups, (74 isolates), (16 isolates) and sp.

Antimicrobial resistance in Enterobacteriaceae is a public health problem. Rodents, can be a potential vector for transmission of multidrug resistant bacteria between animals, humans, and environment. The aim of our study was to assess the level of Enterobacteriaceae present in the intestines of rats collected from different locations in Tunisia, then to determine their antimicrobial susceptibility profiles, to screen extended spectrum β-lactamases-producing strains and determine the molecular mechanism of β-lactams resistance.

Article Synopsis
  • - The study explored the antibacterial and antileishmanial effects of Micromeria nervosa extracts, identifying ursolic acid as the active compound and examining its molecular mechanism of action.
  • - Ethanol and diethyl ether extracts of the plant were tested, with the diethyl ether extract showing strong antibacterial activity against certain resistant bacteria and significant antileishmanial effects against Leishmania species.
  • - Results suggest that M. nervosa extracts and the identified ursolic acid could serve as potential natural alternatives for treating infections, demonstrating low toxicity against host cells and targeting specific gene expressions in pathogens.

Natural Resources Exploitation in Sulfate-Resisting Portland Cement Manufacturing: Towards Quality Improvement and Reduction of Environmental Impact.

Front Chem

August 2022

Laboratoire de Chimie Minérale Appliquée LRCMA (LR19ES02), Faculté des Sciences de Tunis, Université de Tunis El Manar, Campus Universitaire Farhat Hached El Manar, Tunis, Tunisia.

Sulfate-resisting SR) Portland cement is commonly used in building works to improve concrete's durability against external sulfate attack. This attack is considered a very serious chemical aggression that causes damage and cracking of concrete structures. These special cements have a very particular mineralogical composition, CA ≤ 3% and (2CA + CAF) ≤ 20%, which makes the cementitious matrix resistant to sulfate attack.

Intra-Specific Diversity of Isolates: A Key Determinant of Tunisian Zoonotic Cutaneous Leishmaniasis Clinical Polymorphism.

February 2022

Institut Pasteur de Tunis, LR16IPT02, Research Laboratory on Transmission, Control and Immunobiology of Infections (LTCII), 13 Place Pasteur, BP 74, Tunis-Belvédère 1002, Tunisia.

The clinical expression of zoonotic cutaneous leishmaniasis (ZCL) caused by () parasites has a broad spectrum ranging from asymptomatic infection to self-limited cutaneous sores or severe disease. In concert with the host immune responses, the vector variability and the number of bites, genetic variation between isolates might impact on the clinical output of the disease. We investigated herein the intra-specific variability of field isolates independently of host or vector factors and then tried to correlate parasite variability to ZCL severity in corresponding patients.

An analytical method based on liquid chromatography-electrospray ionization-tandem mass spectrometry detection (LC-ESI-MS/MS) has been developed for the determination of pharmaceutical compounds in water samples. Five non-steroidal anti-inflammatory drugs (NSAIDs) namely Naproxen, Ketoprofen, Piroxicam, Diflunisal and Celecoxib were investigated. Magnetic solid phase extraction (MSPE) was used for sample pre concentration of water samples and magnetic carbon nanotubes (Fe3O4-MWCNTs) were considered as solid phase extraction sorbent.

A series of free base and Zn(II) phthalocyanines featuring fluorenyl antennae linked by methoxy or oxo bridges to the phthalocyanine core (Pc) were synthesized and characterized. Selected linear and nonlinear (two-photon absorption) optical properties of these new compounds were subsequently studied. As previously observed for related porphyrin dendrimers bearing 2-fluorenyl peripheral dendrons, an efficient energy transfer occurs from the peripheral antennae to the central phthalocyanine core following excitation in the fluorenyl-based π-π* absorption band of these chromophores.
