Article Synopsis
- Salivary gland tumors (SGTs) are rare and complicated to diagnose and treat, making them a challenging area of research and clinical practice.
- Exosomes, which are tiny vesicles released by all cell types, play significant roles in cancer biology by affecting tumor growth, spread, and the immune response, suggesting they could be key to better understanding SGTs.
- By investigating how exosomes contribute to the progression of these tumors, researchers aim to create new diagnostic methods and therapies, including non-invasive liquid biopsies that could help personalize treatment for patients.
This study presents the characterization of cross-linking parameters of a liquid crystalline epoxy monomer with an aromatic diamine as a curing agent. The mixture tested consisted of bis [4-(10,11-epoxyundecanoyloxy)benzoate] p-phenylene (LCEM) and 1,3-phenylenediamine (1,3-PDA). This paper focuses on the structural characterization of such systems using X-ray analysis.

Recent data highlight a potential interplay between the gut microbiota and the pathophysiology of PD. The degeneration of dopaminergic neurons in PD leads to motor symptoms (tremor, rigidity, and bradykinesia), with antecedent gastrointestinal manifestations, most notably constipation.

The aim of this paper was to validate the Polish translation of the scale, to summarise its consistency with the English language version, and to assess its clinimetric properties.
Clinical Rationale For Study: Gastrointestinal dysfunction is a common and often debilitating manifestation of Parkinson's Disease (PD).
Dedifferentiated chondrosarcoma (DDCS) is a rare subtype of chondrosarcoma, a primary cartilaginous malignant neoplasm. It accounts for up to 1-2% of all chondrosarcomas and is generally associated with one of the poorest prognoses among all chondrosarcomas with the highest risk of metastasis. The 5-year survival rates range from 7% to 24%.

- Novel nanocomposite elastomers made from poly(2-methoxyethylacrylate) (polyMEA) were developed, featuring remarkable properties like high transparency, toughness, and ultra-extensibility.
- The materials utilize tiny silica nanospheres as effective macro-crosslinkers, achieving high yield stress and tensile strength, with some samples stretching up to 1610% before breaking.
- These nanocomposites demonstrate a unique 'plasto-elastic' behavior initially, characterized by energy absorption and partial retraction, but then transition to 'real elastomeric' behavior after significant deformation, presenting potential uses in soft robotics and medical applications.
