Determination of Heavy Metal Levels and Health Risk Assessment of Raw Cow Milk in Guelma Region, Algeria.

During the recent decades, adverse effects of unexpected contaminants, such as heavy metals on raw cow milk quality, have threatened human health. The objective of this study was to determine heavy metal levels in raw milk collected from autochthonous bovine breeds in the eastern region of Algeria. Eighty-eight pooled milk samples were analyzed using atomic absorption spectrometry for Pb, Cd, Cr, Cu, Ni, Fe, and Zn, and dietary risks were estimated for infants, children, and adults with minimum, average, and maximum milk consumption scenarios.

Relationship between endocrine disruptors and obesity with a focus on bisphenol A: a narrative review.

Scientific data suggest that early exposure to endocrine-disrupting chemicals (EDCs) affect -repro, -neuro, -metabolic systems, to which are added other notions such as mixtures, window and duration of exposure, trans-generational effects, and epigenetic mechanisms. In the present narrative review, we studied the relationship between exposure to EDCs with the appearance and development of obesity. Exposure to EDCs like Bisphenol A during the early stages of development has been shown to lead to weight gain and obesity.

Use of multivariate analysis as a tool in the morphological characterization of the main indigenous bovine ecotypes in northeastern Algeria.

Sustainability in livestock farming requires monitoring of autochthonous breeds which are well adapted to the local environment. The morphometric measurements seem to be the first approach which can provide useful information on the suitability of animal genetic resources for selection. In this work, thirteen morphometric variables were used for the phenotypic characterization of 130 adult autochthones cattle randomly selected from 30 local farms in Guelma.

Heavy metals levels in raw cow milk and health risk assessment across the globe: A systematic review.

This systematic review presents the potential toxicity of heavy metals such as lead (Pb), mercury (Hg), cadmium (Cd), iron (Fe), nickel (Ni), aluminum (Al), and copper (Cu) in raw cow milk, focusing on their contamination sources and on the assessment of the related human health risk. Multiple keywords such as "raw cow milk, heavy metals, and human health" were used to search in related databases. A total of 60 original articles published since 2010 reporting the levels of these metals in raw cow's milk across the world were reviewed.

Male rat exposure to low dose of di(2-ethylhexyl) phthalate during pre-pubertal, pubertal and post-pubertal periods: Impact on sperm count, gonad histology and testosterone secretion.

Di (2-ethylhexyl) phthalate (DEHP) is the most ubiquitous endocrine disruptor in the environment. The present study aimed to investigate the low dose effects of DEHP on the male reproductive system of rats exposed during the pre-pubertal, pubertal and post-pubertal periods. Male Wistar rats were daily gavaged by DEHP from postnatal day (PND) 21 to PND 120 with 0.

Early endocrine disruptors exposure acts on 3T3-L1 differentiation and endocrine activity.

Data from last years suggested that early exposure to endocrine disruptors (EDs) can predispose newborns to endocrine dysfunction of adipocytes, obesity, and associated disorders. The implication of EDs at low doses on adipocyte development has been poorly investigated. For instance, vinclozolin (V) is a dicarboximide fungicide widely used in agriculture since the 90's, alone or in mixture with genistein (G), an isoflavonoid from Leguminosae.

Enamel hypomineralization due to endocrine disruptors.

There has been increasing concerns over last 20 years about the potential adverse effects of endocrine disruptors (EDs). Bisphenol A (BPA), genistein (G) and vinclozolin (V) are three widely used EDs having similar effects. Tooth enamel has recently been found to be an additional target of BPA that may be a causal agent of molar incisor hypomineralization (MIH).

Sub-NOAEL amounts of vinclozolin and xenoestrogens target rat chondrogenesis in vivo.

Several endocrine disrupting compounds (EDC) elicit skeletal dysgenesis at pharmacological doses. We have investigated the impact of doses below the "No Observed Adverse Effect" (NOAEL) for vinclozolin (V), an anti-androgenic fungicide, alone or associated with xenoestrogens (Genistein, G and bisphenol-A, BPA). V, G, BPA and their combinations were administered orally to female Wistar rats during gestation and lactation.

A multi-generational study on low-dose BPA exposure in Wistar rats: effects on maternal behavior, flavor intake and development.

Bisphenol A (BPA) is a common endocrine disruptor found as an environmental and food contaminant. It exerts both developmental and behavioral effects, mainly when exposure occurs in early life. The aim of this study was to determine the multi-generational effects of chronic, human-relevant low-dose exposure to BPA on development, maternal behavior and flavor preference in Wistar rats.

Enamel defects reflect perinatal exposure to bisphenol A.

Endocrine-disrupting chemicals (EDCs), including bisphenol A (BPA), are environmental ubiquitous pollutants and associated with a growing health concern. Anecdotally, molar incisor hypomineralization (MIH) is increasing concurrently with EDC-related conditions, which has led us to investigate the effect of BPA on amelogenesis. Rats were exposed daily to BPA from conception until day 30 or 100.

Oral homeostasis disruption by medical plasticizer component bisphenol A in adult male rats.

Objectives/hypothesis: Bisphenol A (BPA) is a synthetic estrogen-like chemical mimetic widely used in the manufacture of polycarbonate plastics and epoxy resins found in numerous consumer products including food packaging, medical devices, and dental sealants. Because it is recovered in fluids and it can reach high levels in saliva, this study aimed to evaluate its safety on oral homeostasis by examining its effects on salivary glands, mouth epithelium, water consumption, and salt preference, each parameter being estrogen sensitive.

Study Design: Randomized controlled trial involving rats.
