IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Evaluation of the Effect of Using Adipose Stem Cells in Bone Augmentation in Patients with Jaw Bone Atrophy: A Systematic Review and Meta-analysis [PDF]

International Journal of Scientific Research in Dental and Medical Sciences
Background and aim: Alveolar ridge bone augmentation is required for patients receiving dental implant therapy who have atrophy of the jaw bone. The latter method does not require bone harvesting, which makes it less invasive during surgery.

Retrospective study of alveolar ridge preservation compared with no alveolar ridge preservation in periodontally compromised extraction sockets

International Journal of Implant Dentistry, 2021
Background To minimize alveolar bone resorption, alveolar ridge preservation (ARP) has been proposed. Recently, interest in improving the feasibility of implant placement has gradually increased, especially in situations of infection such as periodontal ...

Dose-dependent new bone formation by extracorporeal shock wave application on the intact femur of rabbits [PDF]

, 2008
Background: Whereas various molecular working mechanisms of shock waves have been demonstrated, no study has assessed in detail the influence of varying energy flux densities (EFD) on new bone formation in vivo. Methods: Thirty Chinchilla bastard rabbits

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Alveolar Bone Augmentation via In Situ Tissue Engineering

, 2016
In situ tissue engineering, like all tissue engineering, must combine cells capable of tissue regeneration with a signal to promote proliferation and differentiation of these cells together with a matrix (scaffold), on to which the tissue can regenerate.
