A novel approach to cancer screening using the nematode Caenorhabditis elegans-based detection assays.

Background: Early diagnosis of cancer is essential for its effective treatment. Currently, established screening tests are cancer-specific and require screening for each type of cancer separately. The primary objective of cancer research is to develop methods that can detect multiple types of tumors from a single body fluid sample.

The prevalence of methicillin-resistant Staphylococcus aureus among nursing home residents for the elderly in Slovakia.

The objective of our study was to examine the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) among residents of nursing homes for the elderly of selected institutions in two Slovak regions compared to non-institutionalized volunteers of the same age, as well as young volunteers (20-24 years old). Nasal swabs from all participants (n = 424) were processed using standard methods for the isolation and identification of S. aureus and MRSA.

Applications of a powerful model organism Caenorhabditis elegans to study the neurotoxicity induced by heavy metals and pesticides.

The expansion of industry and the use of pesticides in agriculture represent one of the major causes of environmental contamination. Unfortunately, individuals and animals are exposed to these foreign and often toxic substances on a daily basis. Therefore, it is crucial to monitor the impact of such chemicals on human health.

The cuticle plays an important role against toxicity to bisphenol A and bisphenol S.

represents a favorite non-mammalian animal model, which is often used to study the effect of foreign substances on living organisms. Its epidermal barrier is a primary biological barrier that protects nematodes from the toxicity of chemicals. In this study, we investigated the effect of Bisphenol A (BPA), an endocrine disrupting chemical, and its structural analog Bisphenol S (BPS), which is often used as a substitute for BPA in some products, on the behavior of wild type (N2) and mutant strain, which is characterized by the production of abnormal cuticle blisters.
