Comparing the gut microbiota of Sichuan golden monkeys across multiple captive and wild settings: roles of anthropogenic activities and host factors.

BACKGROUND: Captivity and artificial food provision are common conservation strategies for the endangered golden snub-nosed monkey (Rhinopit … porin, macrolides, and clavulanic acid) and secondary metabolite degradation (e.g., naphthalene and atrazine). These microbial alterations implied potential disparities in the health status between AD and wild individuals. AD populations exhibited varying degrees of microbial changes compared to the wild group, implying that the extent of these variations …

Can Xenobiotics Alter the Sex Ratio of Crocodilians in the Wild?

All crocodilians exhibit temperature-dependent sex determination without sex chromosomes. This temperature dependency can be overridden by e … duced more female offspring in A. mississippiensis as compared with the control group. Bisphenol-A, atrazine, 2,4-dichlorophenoxyacetic acid, endosulfan, and Corexit did not alter the sex ratio of A. mississippiensis or Caiman latirostris under the tested conditions. Egg-incubation temperature has pronounced effects on estrogen sensitivity in crocodilian s …

Pesticide mixtures, endocrine disruption, and amphibian declines: are we underestimating the impact?

Amphibian populations are declining globally at an alarming rate. Pesticides are among a number of proposed causes for these declines. Altho … ts of each pesticide alone (0.1 ppb) or in combination were examined. In addition, we also examined atrazine and S-metolachlor combined (0.1 or 10 ppb each) and the commercial formulation Bicep II Magnum, which contains both of these herbicides. These two pesticides were examined in combination because they are persistent throughout the year in the wild. W …

Genetics, Epigenetics, and the Environment: Are Precision Medicine, Provider Compassion, and Social Justice Effective Public Health Measures to Mitigate Disease Risk and Severity?

Environmental forces impacting public health include exposure to toxic substances, adverse childhood experiences (ACEs), diet, and exercise. … more susceptible individuals. For example, children of mothers exposed to the endocrine disruptor, Atrazine, have significantly lower birth length, weight, and head circumference. Moreover, male offspring exhibit genital abnormalities, and all of these effects may be transgenerational. However, analyses of interactions among genes, the environment, and ep …

Development of biofilters to treat the pesticides wastes from spraying applications.

Several studies carried out in Europe showed the importance of direct losses to the contamination of surface water by pesticides. These pest … esticide retained on the biofilters. The results obtained after two years with 5 tracer pesticides (atrazine, carbofuran, diuron, lenacil and simazine) brought on the biofilter installations are very satisfactory since the percentage of retention is generally higher than 95% of the amount applied. In the beginning of 2004, ten new pilot biofilters were ins …

Assessing diet as a modifiable risk factor for pesticide exposure.

The effects of pesticides on the general population, largely as a result of dietary exposure, are unclear. Adopting an organic diet appears to be an obvious solution for reducing dietary pesticide exposure and this is supported by biomonitoring studies in children. However, results of research into the effects of organic diets on pesticide exposure are difficult to interpret in light of the many complexities. Therefore future studies must be carefully designed. While biomonitoring can account for differences in overall exposure it cannot necessarily attribute the source. Due diligence must be

Assessment of a Systematic Screening of Occupational Exposures in Malignant Hemopathies in the Rhone-Alpes Area: Prolymphome Study.

BACKGROUND: Several studies have highlighted the role of environmental exposures in malignant hemopathies etiology. Some patients with malignant hemopathies can be compensated as occupational diseases. The Prolymphome research aimed to assess a systematic screening of occupational exposures in patients with lymphoma or myeloma treated in three hospitals in the Rhône-Alpes region. METHODS: Patients received a self-administered questionnaire to fill in at home to collect their job history and potential occupational exposures to carcinogens. A physician assessed the questionnaire to determine if

Cancer and developmental exposure to endocrine disruptors.

Developing organisms have increased susceptibility to cancer if they are exposed to environmental toxicants during rapid growth and differentiation. Human studies have demonstrated clear increases in cancer after prenatal exposure to ionizing radiation, and there is suggestive evidence that brain tumors and leukemia are associated with parental exposures to chemicals. Animal experiments have demonstrated increased tumor formation induced by prenatal or neonatal exposure to a variety of chemicals, including direct-acting carcinogens and drugs. Recently, natural estrogens have been classified as

Epidemiology and Chemosensitivity of Primary Malignant Bone Tumors at a Teaching Hospital in South Africa: A 5-Year Retrospective Analysis.

BACKGROUND Primary malignant bone tumors (PMBTs) are rare. The incidence of PMBTs varies by geographical location. In our African context, osteosarcoma is the most common PMBT seen; however, there is a variable representation of other PMBTs, likely due to some risk factor in the involved environment. PMBTs have not been studied concerning their geographical location and the role the environment can play as a risk factor. Our study aimed to retrospectively review children and adults treated for PMBTs at our center between 2016 and 2021. MATERIAL AND METHODS We performed a records review of pati
