Abstract
The goal of this research is to explore the anticancer effects of α-enolase targeted peptide (ETP) modified oxaliplatin-loaded Fe3O4 nanoparticles (ETP-PtFe NPs) and their synthesis, characterization, biological function, and characterization on breast
cancer. The ETP-PtFe NPs were studied using transmission electron microscopy, dynamic light scattering, zeta potential analysis, and ultraviolet absorption spectroscopy. Nanocomplexes’ cytotoxicity and cell cycle distribution were studied utilizing flow cytometry tests in a total of
eight trials. A unilateral subcutaneous tumor-bearing rat was created to test the anticancer effects of ETP-PtFe NPs In Vivo. In combination with near-infrared light irradiation, ETP-PtFe suppressed the proliferation of 4TI and MDA-MB-231 breast cancer cells much more than the pure
material group in the CCK8 experiment. ETP-PtFe and NIR light irradiation significantly suppressed 4TI and MDA-MB-231 breast cancer cells in the G2/M phase of the cell cycle compared to the pure material group. This study found that ETP-PtFe combination with near infrared light irradiation
was more effective In Vivo against tumors in mice with unilateral subcutaneous tumors than normal saline combined with near infrared light irradiation. The anticancer and photothermal effects of the ETP-PtFe nanocomposite In Vitro and In Vivo provide a promising notion
and technique for non-invasive early diagnosis and non-surgical treatment of breast cancer’s primary tumor.

Abstract
Selective estrogen receptor modulator (SERM) binds to estrogen receptors (ERs) and acts as both an agonist or an antagonist, depending on the target tissue. Raloxifene and bazedoxifene as SERMs are currently used hormone replacement medicines for postmenopausal osteoporosis. Macrophage colony-stimulating factor (M-CSF) secreted from osteoblasts promotes osteoclastogenesis. We have previously demonstrated that transforming growth factor (TGF)-β induces the synthesis of M-CSF via SMAD2/3, p38 mitogen-activated protein kinase (MAPK), p44/p42 MAPK and c-Jun N-terminal kinase (JNK) in osteoblast-like MC3T3-E1 cells. In the present study, we investigated whether SERM affects the M-CSF synthesis by TGF-β in MC3T3-E1 cells. Raloxifene and bazedoxifene significantly suppressed the synthesis of M-CSF. PPT, an ERα agonist, but not ERB041, an ERβ agonist, inhibited the release of M-CSF. MPP, an ERα antagonist, reversed the suppression by raloxifene of the M-CSF release. Raloxifene attenuated the TGF-β-induced phosphorylation of JNK but not SMAD3, p42 MAPK and p38 MAPK. Bazedoxifene and PPT also inhibited the phosphorylation of JNK. Furthermore, MPP, an ERα antagonist, reversed the suppression by both raloxifene and bazedoxifene of the phosphorylation of JNK. Our results strongly indicate that raloxifene and bazedoxifene, SERMs, suppress the TGF-β-induced synthesis of M-CSF through ERα-mediated inhibition of JNK pathway in osteoblasts.

Abstract
Objective: To analyze, in a retrospective study, the lateral tunnel position of the graft femur by CT after arthroscopic ACL reconstruction via the anteromedial (AM) approach and the tunnel angle shown on X-ray. Methods and Materials: 60 patients undergoing arthroscopic
ACL reconstruction via AM approach with 4 femoral hamstring tendon grafts were investigated from October 2019 to October 2021. Postoperative orthogonal x-rays and computed tomography (CT) scans were obtained, and the position of the femoral tunnel obtained after CT reconstruction was correlated
with the Bernard-Hertel grid. The angle of the resulting femoral tunnel on the orthogonal x-ray was analyzed against the CT tunnel position. Results: In the study, the anterior–posterior orientation was forward (P = 0.001) and the high-low orientation was similar (taken
as 20%, P = 0.066) or slightly higher (taken as 21%, P = 0.025) compared to the AM beam localization in the two-beam reconstruction. Overall, the femoral tunnel angle on non-weight-bearing orthogonal x-ray was negatively correlated with the anterior–posterior (AP) position
of the femoral tunnel centre as shown on CT (P = 0.004, r =−0.368) and positively, but weakly, correlated with the high-low (HL) position (P = 0.049, r = 0.254). Conclusion: Non-weight-bearing orthogonal X-rays only can make approximate predictions
about the distribution of anatomical reconstruction, I.D.E.A.L reconstruction.

Abstract
Although bone tissue has the ability to heal itself, beyond a certain point, bone defects cannot rebuild themselves, and the challenge is how to promote bone tissue regeneration. Iron oxide nanoparticles (IONPs) are a magnetic material because of their excellent properties, which enable them to play an active role in bone regeneration. This paper reviews the application of IONPs in bone tissue regeneration in recent years, and outlines the mechanisms of IONPs in bone tissue regeneration in detail based on the physicochemical properties, structural characteristics and safety of IONPs. In addition, a bibliometric approach has been used to analyze the hot spots and trends in the field in order to identify future directions. The results demonstrate that IONPs are increasingly being investigated in bone regeneration, from the initial use as magnetic resonance imaging (MRI) contrast agents to later drug delivery vehicles, cell labeling, and now in combination with stem cells (SCs) composite scaffolds. In conclusion, based on the current research and development trends, it is more inclined to be used in bone tissue engineering, scaffolds, and composite scaffolds.

Abstract
Water constitutes roughly a quarter of the cortical bone by volume yet can greatly influence mechanical properties and tissue quality. There is a growing appreciation for how water can dynamically change due to age, disease, and treatment. A key emerging area related to bone mechanical and tissue properties lies in differentiating the role of water in its four different compartments, including free/pore water, water loosely bound at the collagen/mineral interfaces, water tightly bound within collagen triple helices, and structural water within the mineral. This review summarizes our current knowledge of bone water across the four functional compartments and discusses how alterations in each compartment relate to mechanical changes. It provides an overview on the advent of- and improvements to- imaging and spectroscopic techniques able to probe nano-and molecular scales of bone water. These technical advances have led to an emerging understanding of how bone water changes in various conditions, of which aging, chronic kidney disease, diabetes, osteoporosis, and osteogenesis imperfecta are reviewed. Finally, it summarizes work focused on therapeutically targeting water to improve mechanical properties.

Abstract
In this study, the purpose is to examine the impact of nano-hydroxyapatite (Nano-HAP) on human osteosarcoma cell (U2OS) growth and apoptosis (cell death). For reaching this goal an apoptosis kit was employed to determine the influence of Nano-HAP on apoptosis in human osteosarcoma cells
U2OS, which were treated with different doses of Nano-HAP; FDA staining was used to elucidate the effect of Nano-HAP on cell adhesion. U2OS adhesion was not affected by Nano-HAP at different concentrations, however the production of U2OS was dramatically reduced. U2OS osteosarcoma cell growth
was considerably inhibited at the doses of 50 g/ml and 800 g/ml, respectively. In conclusion, osteosarcoma cell growth and apoptosis are greatly inhibited by nano-HAP, although there is no clear linear link between nanoparticle concentration and the impact.

Abstract
Modern biomedicine aims to develop integrated solutions that use medical, biotechnological, materials science, and engineering concepts to create functional alternatives for the specific, selective, and accurate management of medical conditions. In the particular case of tissue engineering, designing a model that simulates all tissue qualities and fulfills all tissue requirements is a continuous challenge in the field of bone regeneration. The therapeutic protocols used for bone healing applications are limited by the hierarchical nature and extensive vascularization of osseous tissue, especially in large bone lesions. In this regard, nanotechnology paves the way for a new era in bone treatment, repair and regeneration, by enabling the fabrication of complex nanostructures that are similar to those found in the natural bone and which exhibit multifunctional bioactivity. This review aims to lay out the tremendous outcomes of using inorganic nanoparticles in bone healing applications, including bone repair and regeneration, and modern therapeutic strategies for bone-related pathologies.
