Intraoperative modification of use and stabilization of the Axon system (Synthes) for occipito-cervical fusion in a patient treated oncologically due to plasmocytoma is presented. Pathological fracture, range of the process and damage of anterior cervical fusion necessitated the use of occipito-cervical stabilization. Different anatomical conditions within the occipital bone in the form of its thinning was observed. Fixing with screws was impossible due to the bone structure. In consequence, modification of stabilization with an ad hoc elaborated technique (burr holes in the occipital bone and stabilization with titanium wire) was implemented. Modifications and specific indications related to the clinical course of plasmocytoma are discussed.

The complexation of nucleic acids and collagen forms a platform biomaterial greater than the sum of its parts. This union of biomacromolecules merges the extracellular matrix functionality of collagen with the designable bioactivity of nucleic acids, enabling advances in regenerative medicine, tissue engineering, gene delivery, and targeted therapy. This review traces the historical foundations and critical applications of DNA-collagen complexes and highlights their capabilities, demonstrating them as biocompatible, bioactive, and tunable platform materials.

Non-small cell lung cancer (NSCLC) has emerged as one of the most prevalent malignancies worldwide. N6-methyladenosine (mA) methylation, a pervasive epigenetic modification in long noncoding RNAs (lncRNAs), plays a crucial role in NSCLC progression. Here, we report that mA modification and the expression of the lncRNA stem cell inhibitory RNA transcript (SCIRT) was significantly upregulated in NSCLC tissues and cells.

Kinetic stability, in addition to thermodynamic stability, can directly impact protein lifetime, abundance, and the formation of alternative, sometimes disruptive states. However, we have very few measurements of protein unfolding rates or how mutations alter these rates, largely due to technical challenges associated with their measurement.

Understanding accumulation beyond the mycomembrane of ( ) is crucial for developing effective antimycobacterial agents. This study investigates two design principles commonly found in natural products and mammalian cell-permeable peptides - backbone -methylation and macrocyclization - aimed at enhancing accumulation.
