Effect of Cadmium on Oxidative Stress Indices and Vitamin D Concentrations in Children.

Heavy metal poisoning can have serious health consequences, including damage to the brain, kidneys, and other organs. Cadmium is a toxic heavy metal that can accumulate in the body over time and the exposure to this element has been linked to a variety of adverse health effects. Cadmium toxicity can lead to an imbalance in the cellular redox state and be a source of oxidative stress.

Balloon pulmonary angioplasty in chronic thromboembolic pulmonary hypertension: a multicentre registry.

Background: Balloon pulmonary angioplasty (BPA) is a promising therapy for patients with chronic thromboembolic pulmonary hypertension (CTEPH) who are ineligible for pulmonary endarterectomy.

Aims: The present study aimed to evaluate the safety and efficacy of BPA for CTEPH using the first multicentre registry of a single European country.

Methods: Data were obtained from the Database of Pulmonary Hypertension in the Polish Population (NCT03959748), a prospective, multicentre registry of adult and paediatric pulmonary arterial hypertension (PAH) and CTEPH, for a total of 236 patients with confirmed CTEPH (124 women; mean age 67 years) who underwent 1,056 BPA procedures at eight institutions in Poland.

Characteristics and outcomes of patients with chronic thromboembolic pulmonary hypertension in the era of modern therapeutic approaches: data from the Polish multicenter registry (BNP-PL).

Background: Significant achievements in the treatment of chronic thromboembolic pulmonary hypertension (CTEPH) have provided effective therapeutic options for most patients. However, the true impact of the changed landscape of CTEPH therapies on patients' management and outcomes is poorly known. We aimed to characterize the incidence, clinical characteristics, and outcomes of CTEPH patients in the modern era of CTEPH therapies.

The use of biodegradable polymers in design of cellular scaffolds.

The objective of this work was to demonstrate the usage of biodegradable polymers, made of calcium alginate and dibutyrylchitin, in the design of cellular scaffolds having broad application in reconstructive therapy (dentistry, orthopedics). To visualize cells seeded on calcium alginate and dibutyrylchitin polymers DAPI staining of fibroblasts nuclei was used. The cytotoxicity of the materials and microscopic evaluation of the viability of seeded cells was tested with a PKH 67 fluorescent dye.
