13. Hybrid Sandwich Particleboard Made with Sugarcane, Pínus Taeda Thermally Treated and Malva Fibre from Amazon
A multilayer particleboard panels, consisted of sugarcane bagasse reinforced composite as core material and hybrid composites made with Pinus taeda particles and Malva fibres as facing materials, were designed and evaluated in this work. Tukey test was used to identify the effect of the facing material, considering different combinations of Pinus taeda parti

14. Nandrolone decanoate appears to increase bone callus formation in young adult rats after a complete femoral fracture
Abstract Purpose: To evaluate the influence of nandrolone decanoate on fracture healing and bone quality in normal rats. Methods: Male rats were assigned to four groups (n=28/group): Control group consisting of animals without any intervention, Nandrolone decanoate (DN) group consisting of animals that received intramuscular injection of nandrolone decano

15. Evaluation of the anti-osteoporotic effect of Ginkgo biloba L. in Wistar rats with glucocorticoid-induced-osteoporosis by bone densitometry using dual-energy x-ray absorptiometry (DEXA) and mechanical testing
ABSTRACT Evaluate the effect of the extract of Ginkgo biloba in the bone alkaline phosphatase, bone mineral density, in the mechanical properties of the tibia in rats with glucocorticoid-induced-osteoporosis. After osteoporosis induction, the rats were divided into five groups: Osteoporosis; EGb1 (28 mg/Kg); EGb2 (56 mg/Kg); alendronate (0.2 mg/animal) and c

16. Correlation between ultrasound velocity and densitometry in fresh and demineralized cortical bone
OBJECTIVE: To compare ultrasound propagation velocity with densitometry in the diaphyseal compact cortical bone of whole sheep metatarsals. METHODS: The transverse ultrasound velocity and bone mineral density of 5-cm-long diaphyseal bone segments were first measured. The bone segments were then divided into four groups of 15 segments each and demineralized

17. Hypocalcemia development in patients operated for primary hyperparathyroidism: Can it be predicted preoperatively?
ABSTRACT Objective Primary hyperparathyroidism (PHP) is a common endocrine disease, and its most effective treatment is surgery. Postoperative hypocalcemia is a morbidity of parathyroid surgeries, and it may extend hospitalization durations. The purpose of this study is to determine the predictive factors related to the development of hypocalcemia and hung

18. A validated and densitometric HPTLC method for the simultaneous quantification of reserpine and ajmalicine in Rauvolfia serpentina and Rauvolfia tetraphylla
ABSTRACT High performance thin layer chromatographic method (HPTLC) has been developed for the quantification of reserpine and ajmalicine in root part of two different population of Rauvolfia serpentina (L.) Benth. ex Kurz and Rauvolfia tetraphylla L., Apocynaceae, collected from Punjab and Uttarakhand. HPTLC of methanolic extract of root containing indole a

19. BIOCHEMICAL ANALYSIS AND BONE REMODELING IN RESPONSE TO OOPHORECTOMY AND AQUATIC TRAINING
ABSTRACT Objective: To investigate whether swimming could prevent bone loss and could be indicated to assist in treatment of osteoporosis. Methods: Female rats were divided into 4 groups (n=6), two of them were oophorectomized. Animals from two groups, one oophorectomized and another not oophorectomized, underwent aquatic training for eight weeks. After tr

20. Analysis of fracture healing in osteopenic bone caused by disuse: experimental study
Osteoporosis has become a serious global public health issue. Hence, osteoporotic fracture healing has been investigated in several previous studies because there is still controversy over the effect osteoporosis has on the healing process. The current study aimed to analyze two different periods of bone healing in normal and osteopenic rats. Sixty, 7-week-o

21. Whole-body vibration improves fracture healing and bone quality in rats with ovariectomy-induced osteoporosis
PURPOSE: To investigate the effect of vibration therapy on the bone callus of fractured femurs and the bone quality of intact femurs in ovariectomized rats. METHODS: Fifty-six rats aged seven weeks were divided into four groups: control with femoral fracture (CON, n=14), ovariectomized with femoral fracture (OVX, n=14), control with femoral fracture plus v

22. Digital vertebral morphometry performed by DXA: a valuable opportunity for identifying fractures during bone mass assessment
Objectives To evaluate the usefulness of vertebral morphometry in identifying unreferred vertebral fractures and correlate potential risk factors. Subjects and methods Female patients above 45 years, postmenopausal for at least 2 years, diagnosed with osteoporosis and undergoing treatment for at least three months were considered eligible. All of them under

24. Histomorphometric analysis of the femoral neck in patients with and without femoral neck fracture
OBJECTIVE: To determine, through bone histomorphometry in femoral neck, whether there are differences in the cancellous bone of the proximal femur from female patients over 60 years old who had femoral neck fracture and similar patients who did not have such fracture.METHODS: We analyzed the trabecular part of the femur of 13 female patients, aged over 60 ye
