13. Controversies in the treatment of postmenopausal osteoporosis: How long to treat with bisphosphonates?
ABSTRACT Osteoporosis is a systemic skeletal disease characterized by reduced bone mass and deterioration of bone tissue microarchitecture leading to an increased risk of fractures. Fragility fractures, especially hip fractures, are associated with a significant reduction in the physical function and quality of life of affected patients, as well as increased

14. Role of miRNA-182 and miRNA-187 as potential biomarkers in prostate cancer and its correlation with the staging of prostate cancer
ABSTRACT Purpose The microRNAs expression has emerged as a potential biomarker for the diagnosis and prognosis of prostate cancer. This study investigated the expression of miRNA-182 and miRNA-187 in prostate cancer patients and established a correlation between miRNA expression and staging of prostate cancer. Materials and Methods This prospective obser

16. Signet ring cells in carcinomatous lymphangitis due to gastric adenocarcinoma,
Abstract Cutaneous metastases are rare. They usually present as nodules or tumors. Diagnosis is based on histopathological examination and prognosis is unfavorable. This report describes the case of a female patient, 72 years old, with surgically treated gastric antrum adenocarcinoma. Pathology showed poorly differentiated adenocarcinoma with signet ring cel

17. New Synthetic Quinolines as Cathepsin K Inhibitors
Cathepsin K is a papain-like cysteine protease and is responsible for collagen degradation in bone tissue and thus represents an important target for the development of new therapies for treating diseases such as osteoporosis. Quinolines are an important class of heterocyclic molecular leads with a great pharmacological potential and represent a relevant sca

18. Upconversion 3D Printed Composite with Multifunctional Applications for Tissue Engineering and Photodynamic Therapy
Upconversion nanoparticles (UCNPs) are suitable materials for bioapplications due to their ability to emit visible light under near infrared (NIR) excitation, in the biological transparency range. Polycaprolactone(PCL)-based scaffolds are widely used in tissue engineering in combination with inorganic compounds to improve bioactivity and osteoconductive prop

19. New insights of growth hormone (GH) actions from tissue-specific GH receptor knockouts in mice
ABSTRACT In order to provide new insights into the various activities of GH in specific tissues, recent advances have allowed for the generation of tissue-specific GHR knockout mice. To date, 21 distinct tissue-specific mouse lines have been created and reported in 28 publications. Targeted tissues include liver, muscle, fat, brain, bone, heart, intestine, m

20. Tuberculous Osteomyelitis Mimicking a Lytic Bone Tumor: Report of Two Cases and Literature Review
Resumo A osteomielite tuberculosa é uma forma incomum de tuberculose (TB) e o acometimento isolado da articulação do punho pelo TB é particularmente raro. Os sintomas e a manifestação clínica imitam outras doenças; portanto, um diagnóstico cuidadoso é necessário. Os autores apresentam dois casos de pacientes com massa nas partes moles e lesão ós

21. Comparison of subcutaneous inflammatory response to commercial and engineered zinc hydroxyapatite implants in rabbits
RESUMO A hidroxiapatita (HA) é amplamente utilizada como biomaterial para reparo ósseo e revestimento de próteses metálicas. As principais limitações dos atuais compostos comerciais de hidroxiapatita sintética incluem alto custo e menor disponibilidade, especialmente para fins de medicina veterinária. Além disso, acredita-se que a biocompatibilidade

22. First record of growth rings for 11 native subtropical anuran species of South America
Abstract: Skeletochronology is the most accurate method to estimate a population age structure. The methodology is based on the analysis of secondary bone tissue in order to count growth rings. This study aimed to provide initial data, allowing researchers to further work out in the age of individuals and populations, sampling evidence of the presence of gro

23. Fat grafting associated with negative pressure wound therapy
Abstract Purpose: To describe a case report of FG associated with NPWT in the treatment of complex wound on the distal third of the lower limb with bone exposure. Case Report: A 59-year-old patient with chronic left tibial osteomyelitis since childhood underwent extensive debridement of the distal tibial diaphysis (40% of bone thickness per 10 cm extension

24. Impact of calcium aluminate cement with additives on dental pulp-derived cells
Abstract Calcium aluminate cement (CAC) has been highlighted as a promising alternative for endodontic use aiming at periapical tissue repair. However, its effects on dental pulp cells have been poorly explored. Objective: This study assessed the impact of calcium chloride (CaCl2) and bismuth oxide (Bi2O3) or zinc oxide (ZnO) additives on odontoblast cell re
