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

open access: yesMolecular 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.

Influence of the mechanical environment upon the healing of segmental bone defects in the rat femur [PDF]

open access: yes
Loss of large segments of bone creates critical size defects (CSDs). These fail to heal spontaneously and present major clinical challenges to orthopaedic surgeons. The research described in this thesis is based upon the hypothesis that the healing of

BONE HEALING IN MICE: DOES IT FOLLOW GENERIC MECHANO-REGULATION RULES?

open access: yesFacta Universitatis. Series: Mechanical Engineering, 2015
Mechanical signals are known to influence bone healing progression. Previous studies have postulated inter-species differences in the mechanical regulation of the bone healing process.

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

open access: yesMolecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Cell‐cycle‐specific lesion evolution rather than inhibition of double‐strand‐break repair underpins cisplatin radiosensitization

open access: yesMolecular Oncology, EarlyView.
We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

The Effect of Oral Isotretinoin on Bone Healing in Rabbit Rhinoplasty Model: An Experimental Study

open access: yesİstanbul Medical Journal, 2019
Introduction:Since the age at which rhinoplasty is frequently performed is also the age at which acne is frequently seen, a person may be a candidate for both this surgery and isotretinoin therapy.

Bone physiology and bone healing [PDF]

open access: yesNeurosurgical Focus, 2002
In the not-too-distant past, spine surgeons performed spinal arthrodesis procedures and bone union would occur. This wish, however, was often not realized, and a nonunion (pseudarthrosis) developed in 10 to 45% of patients. Although the introduction of adjunctive spinal instrumentation reduced the nonunion rate, it remained significant, ranging from 5 ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Evaluation of Bone Healing on Sandblasted and Acid Etched Implants Coated with Nanocrystalline Hydroxyapatite: An In Vivo Study in Rabbit Femur

open access: yesInternational Journal of Dentistry, 2014
This study aimed at investigating if a coating of hydroxyapatite nanocrystals would enhance bone healing over time in trabecular bone. Sandblasted and acid etched titanium implants with and without a submicron thick coat of hydroxyapatite nanocrystals ...
