There is considerable evidence that Bisphenol S (BPS) induces various toxicological effects and is an industrial health issue. However, little data are available on the in vivo effects of BPS on the liver, a major target of drug toxicity. In this study, we evaluated the potential harmfulness of low levels of BPS in the liver of male mice.

Acromegaly is a rare endocrine disorder leading to an acquired physical disfigurement and multisystem damage. It is caused in over 95% of cases by a secreting pituitary adenoma. Latency period between disease onset and diagnosis is mainly 10 years due to progressive chronic evolution and exposure to high levels of GH and IGF-1.

Introduction: L'allergie aux protéines du lait de vache (APLV) est l'allergie alimentaire la plus fréquente au cours des premières années de vie. Elle est souvent associée à l'introduction des préparations à base de lait de vache et constitue une maladie rare chez les nourrissons allaités.

Objectif: Rapporter le cas d'une APLV chez un nourrisson sous allaitement maternel exclusif.

Epoxiconazole is a worldwide fungicide used to control fungal diseases. Although to its hazardous effects in non-target species, little information is available in the literature to show the cardiotoxic effects of EPX in male rats. Thus, our investigation aimed to assess the outcomes of EPX exposure on some biochemical parameters, the generation of oxidative stress, DNA fragmentation and histopathological alterations in the heart tissue.

Hospital effluent (HE) is one of the most important sources of pharmaceuticals released into the environment. This kind of pollution is a recognized problem for both human health and aquatic life. Consequently, in the present study, we assessed the effects of untreated hospital effluent on mice via biochemical and histopathological determinations.

Tebuconazole (TEB) is a broad-spectrum conazole fungicide that has been used in agriculture in the control of foliar and soil-borne diseases of many crops. The present study has investigated the adverse effects of subchronic exposure to TEB on the kidney of male rats. Animals were divided into four equal groups and treated with TEB at increasing doses 0.

Because of the extensive use of phthalates for domestic, medical, and industrial applications, the evaluation of their toxic effects is of major concern to public health. The aim of the present study was to assess the propensity of di (2-ethylhexyl) phthalate (DEHP), one of the most used phthalates, to cause oxidative cardiac damage in mice. DEHP was administered intraperitoneally at doses of 5, 50, and 200 mg/kg body weight for 30 consecutive days in BALB/c mice.

Triflumuron (TFM) is one of the most widely used insecticides over the world. It is a benzoylphenyl urea that belongs to the class of insect growth regulators. This insecticide acts by inhibiting insect's chitin synthesis and by consequences, making insect more susceptible to pathogens and malformations.

Purpose: Clopidogrel non-responsiveness is multifactorial; several genetic and non-genetic factors may contribute to impaired platelet inhibition. The goal of this study is to determine the effect of the cytochrome P450 CYP2C19*2 polymorphism on the platelet response to clopidogrel in patients with and without diabetes mellitus (DM).

Methods: We conducted an observational study in patients with coronary artery disease and consequent exposure to clopidogrel therapy (75 mg/day for at least 7 consecutive days).

Poisoning and accidental oral intoxication are major health problems worldwide. Considering the insufficient efficacy of the currently available detoxification treatments, a pioneering oral detoxifying adsorbent agent based on a single biocompatible metal-organic framework (MOF) is here proposed for the efficient decontamination of drugs commonly implicated in accidental or voluntary poisoning. Furthermore, the in vivo toxicity and biodistribution of a MOF via oral administration have been investigated for the first time.

This study reports the clinical and biological signs, as well as the morphological aspect and the chemical composition of the calculus during the biliary stones. The study population consisted of 31 patients with an average age of 49 years (30 women and one man) with biliary lithiasis and who had cholecystectomy. Hepatic colic and epigastralgia were the most evocative clinical signs.

Background: Nutritional choices, which include the source of dietary fatty acids (FA), have an important significant impact on coronary artery disease (CAD). We aimed to determine on patients with CAD the relationships between Trans fatty acids (Trans FA) and different CAD associated parameters such as inflammatory and oxidative stress parameters in addition to Gensini score as a vascular severity index.

Methods: Fatty acid profiles were established by gas chromatography from 111 CAD patients compared to 120 age-matched control group.

Background: Some factors related to diet are known to be involved in the progression of atherosclerosis in humans.

Methods: The relationship between plasma fatty acid (FA) levels and the severity of coronary artery disease (CAD), evaluated by Gensini score (GS), was investigated in CAD Tunisian patients compared to controls. Lipid profiles were analyzed, GS was calculated in CAD and non-CAD patients and compared to controls.

Background: Adipose tissue is an important endocrine organ that secretes a number of adipokines, like Resistin (RETN); it's an adipocytes-secreted cytokine and has been proposed as a link between obesity and diabetes. Many resistin gene polymorphisms were described and their implication in obesity was controversial. This study was to investigate the prevalence of single nucleotide polymorphisms (SNPs) in RETN gene 420C/G; 44G/A; 62G/A; 394C/G and 299 G/A and their association with Resistin level and obesity in Tunisian volunteers.

We identified and quantified a variety of mineral elements in 18 tobacco samples purchased from a Tunisian market. In total, 25 mineral elements have been measured in cigarettes, water pipe tobacco, and smokeless tobacco using inductively coupled plasma-optical emission spectroscopy following microwave-assisted digestion. Statistical analyses were performed using SPSSTM, version 18.

Primary hyperoxalurias (PH) are inborn errors in the metabolism of glyoxalate and oxalate with recessive autosomal transmission. As a result, an increased endogenous production of oxalate leads to exessive urinary oxalate excretion. PH type 1, the most common form, is due to a deficiency of the peroxisomal enzyme alanine: Glyoxylate aminotransferase (AGT) in the liver.

Background: The goal of this study was to determine the value of systolic time intervals and their change during Valsalva maneuver (VM) in the diagnosis of left ventricular dysfunction (LVD) in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).

Methods: We included 166 patients admitted to the emergency department for AECOPD. Measurement of systolic time intervals included electromechanical activation time (EMAT), left ventricular ejection time (LVET), and EMAT/LVET ratio.

Article Synopsis
  • The study examines the toxic effects of acetamiprid, a common neonicotinoid pesticide, on male Wistar rats over 60 days, using three different doses (1/20, 1/10, and 1/5 of lethal dose).
  • Results showed significant weight loss and increased liver size at the highest dose, along with changes in blood components like reduced red blood cells and increased white blood cells at higher doses.
  • Acetamiprid also caused liver toxicity, indicated by elevated liver enzymes and decreased antioxidant activity, suggesting potential damage to liver cells and overall hepatotoxicity.
