Clinical characteristics of the Ala21Val variant in the myelin proteolipid protein 1 (PLP1) gene associated with Pelizaeus-Merzbacher disease in a Brazilian male patient.

Here, we report the case of a 29-year-old male with classic Pelizaeus-Merzbacher disease (PMD) harboring the PLP1 variant NM_000533.5:c.62 C > T, leading to an NP_000524.

Tideglusib enhances ALP activity and upregulates RANKL expression in Osteoblast-macrophage Co-cultures within a 3D collagen scaffold.

Objectives: Tideglusib (Tx) is known for its osteogenic potential, yet its effects on the interplay between osteoblasts and M1 macrophages remain underexplored. This in vitro study aimed to isolate and evaluate both the individual and combined roles of M1 macrophages and osteoblasts in macrophage differentiation and osteoblast function, specifically focusing on how these interactions influence protein expression of osteogenesis and osteoclastogenesis in the presence or absence of Tx.

Methods: Osteoblast and macrophage cells were co-cultured in direct contact for 24 and 48 h, with or without the presence of Tx.

In Vitro Degradation of Collagen-Based Membranes for Guided Bone Regeneration After Zn-Ions or Doxycycline Functionalization.

Collagen-based membrane is the most commonly used biomaterial for guided bone and tissue regeneration; however, its barrier function can be threatened by its rapid degradation pattern, affecting the success of the regeneration process. Differences in the origin and functionalization of the membrane to obtain better properties can alter the degradation rate. The objective of this study was to examine the biodegradation pattern of two commercially available collagen membranes (Jason and Collprotect) manufactured using porcine pericardium or dermis, doped or not with zinc-ions or doxycycline, in a period up to 21 days.

Encapsulation of a 5FU-curcumin hybrid on bacterial nanocellulose for colorectal cancer treatment.

The traditional treatment of colorectal cancer (CRC) involves a combination of chemotherapy and synthetic and natural drugs. In this study, a hybrid compound of 5-fluorouracil-curcumin encapsulated in bacterial nanocellulose (BNC) was evaluated for CRC treatment. Bacterial nanocellulose was produced using K.

Ultra-high-energy gamma-ray bubble around microquasar V4641 Sgr.

Microquasars are laboratories for the study of jets of relativistic particles produced by accretion onto a spinning black hole. Microquasars are near enough to allow detailed imaging of spatial features across the multiwavelength spectrum. The recent extension measurement of the spatial morphology of a microquasar, SS 433, to TeV gamma rays localizes the acceleration of electrons at shocks in the jet far from the black hole.
