The emergence and subsequent development of bone tool technologies represents an important step in the evolution of human behavior. Here we present a technological, morphometric and functional analysis of ten bone tools ...

Bone metastasis is a frequent and incurable consequence of advanced prostate cancer (PC). This process originates through an interplay between disseminated tumor cells and heterogeneous bone resident cells in the metasta...

Osteoporosis is a very common disease nowadays, and it is mostly seen in postmenopausal women. In postmenopausal women, with the decrease of estrogen, directly or indirectly, it makes the decrease of bone mineral density...

Abstract Oracle bone inscriptions, the earliest known form of Chinese writing, hold immense historical and linguistic significance. However, existing digital datasets are typically limited to isolated characters and lack...

BackgroundPrimary malignant bone tumors are aggressive neoplasms that frequently affect adolescents and young adults. Limb-sparing surgery (LSS) has become the preferred surgical approach when oncologically feasible; how...

The aim of the present study was to quantify the parasite load ofLeishmania infantum in dogs using real-time PCR (qPCR). Bone marrow, lymph node and spleen samples were taken from 24 dogs serologically positive for L. in...

Introduction: The American College of Radiology (ACR) Bone-Reporting and Data System (Bone-RADS) gave a structured framework for assessing and reporting bone tumours. Aim: To evaluate the diagnostic performance of the...

Infrabony pocket therapy is needed to eliminate pocket wall, creating easy to clean conditions for new attachment, and bone regeneration. Biphasic calcium sulfate (BCS) bone grafts combined with collagen membranes are kn...

Abstract Studies in humans suggest that vitamin K is involved in the regulation of bone remodeling, but the precise mechanism at play remains unknown. In cells, vitamin K functions as a co-factor for the γ-glutamyl carb...

Skeletal age assessment is one of the important applications of hand radiography in the area of pediatric radiology. Features analysis of the carpal bones can reveal the important information for skeletal age assessment....

Aims: Patient-specific Ti-6Al-4V lattice implants present a new era for reconstruction of weightbearing segmental defects; however, robust clinical data from larger cohorts with longer follow-up remain limited. Building ...

Foram utilizados 12 cordeiros machos, inteiros, com peso médio de 31,6kg. Os cordeiros foram alimentados com dietas à base de milho e farelo de soja, suplementadas com diferentes fontes de cálcio: calcário calcítico...

Abstract Bone regeneration of oral and maxillofacial defects in situ remains a significant clinical challenge. This study investigates the synergistic effects of phosphorus (P) and zinc (Zn) co-doping in wollastonite bio...

Aging is associated with numerous physiological, musculoskeletal, and neurological impairments including a loss of muscle, strength, function, bone mineral, and cognition. Strength training is an effective intervention ...

Cyclophosphamide (CP) is commonly used in cancer chemotherapy and the treatment of autoimmune diseases. In clinical applications, it exhibits the side effect of progressive anemia. Donkey serum albumin (DSA) is the most ...

Aims Deleterious effects of metabolic syndrome (MS) on bone are still controversial. In this study we evaluated the effects of a fructose-induced MS, and/or an oral treatment with metformin on the osteogenic potential of...

Abstract Objective To compare the peri-implant mucosal stability between an “open healing” approach (test) during immediate dental implant placement with bone grafting and immediate transmucosal provisionalization (n...

Introduction The imbalance between osteoblasts and osteoclasts is central to osteoporosis.Insulin like growth factor (IGF) has protective effects on bone. As an IGF-binding protein, the role of IGFBP in bone has also beg...

Reconstructing the faunal palaeoecology of landscapes occupied by Neanderthals and their competitors is essential for better understanding their ecological niche, decisions, and behaviors. Late Pleistocene faunal assembl...

Objective: In this finite element study, the biomechanical effects of force application at different lingual versus labial sites on a maxillary central incisor with alveolar bone loss and proclination were compared. Meth...
