In vivo assessment of oxidative stress, neurotoxicity and histological alterations induction in the marine gastropod Stramonita haemastoma exposed to CrO and AlO nanoparticles.

The increased use of nanoparticles (NPs) is expected to raise their presence in the marine ecosystem, which is considered as the final destination of released NPs. This study investigated the toxicity of CrO (42 nm) and AlO (38 nm) NPs (1, 2.5, and 5 mg/L) on the digestive glands of Stramonita haemastoma for 7, 14, and 28 days by oxidative stress biomarkers, neurotoxicity indicator assessment, and histological study.

Determination of the Toxic Effects of Heavy Metals on the Morpho-Anatomical Responses of the Leaf of as a Biomonitoring Tool.

leaves act as sensitive barometers for trace heavy metal pollution, as revealed by their pronounced anatomical responses in a constructed wetland. Monthly water samples and leaf tissue were collected over three consecutive months in 2018 from the Burgas Lake wetlands (Taoura), northeast Algeria. While physical and chemical parameters improved after treatment, atomic absorption spectrometry (Perkin Elmer A Analyst 800 AAS) detected persistent trace levels of cadmium, chromium, and lead in both the treated water and leaf tissue, highlighting the need for continued phytoremediation efforts.

Assessing allergic rhinitis in developing countries.

Background: Allergic rhinitis (AR) affects 5% to 40% of the general population. In developing countries, AR is poorly documented and tracked due to a lack of appropriate diagnostic tools.

Objective: 1) To validate a questionnaire standardised in industrialised countries to ascertain AR, the Score For Allergic Rhinitis (SFAR), in developing countries; 2) to better understand AR prevalence previously reported from developing countries by comparing results from the SFAR and the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaires.

[Cystic pulmonary malformations: clinical and radiological polymorphism. A report on 30 cases].

Objectives: This report describes different clinical pictures of cystic pulmonary malformation (CPM) and problems in diagnosis.

Patients And Methods: Cases of CPM between 01 January 1994 and 31 December 2004 diagnosed in our institution were reviewed.

Results: Thirty-three cases of CPM were diagnosed in 30 children.

Diabetic acido-ketosis revealing thiamine-responsive megaloblastic anemia.

Thiamine-responsive megaloblastic anemia (TRMA) is a rare autosomal recessive disorder characterized by megaloblastic anemia, diabetes mellitus and progressive sensorineural deafness. We report the cases of two infants, aged 4 and 5 months, hospitalized for diabetic ketoacidosis requiring insulin therapy. Laboratory tests revealed megaloblasic anemia, thrombocytopenia and normal thiamine level.
