The rise in oestrogen levels at menarche in girls is associated with a large reduction in bone turnover markers. This reduction reflects the closure of the epiphyseal growth plates, the reduction in periosteal apposition and endosteal resorption within cortical bone, and in bone remodelling within cortical and cancellous bone. Oestrogen promotes these changes, in part, by promoting apoptosis of...

Factors other than low bone mass, such as changes in bone quality, may contribute to fracture risk. Non-enzymatic glycation alters bone’s organic matrix [1] and creates collagen crosslinks, collectively termed advanced glycation end products (AGEs) [2]. AGEs accumulation with age stiffens bone's organic matrix, ultimately leading to fracture [3]. Cell culture work in animal models shows increas...

Abstract To reduce complications related to the osteosynthesis plating system, use of a patient-specific plate design was proposed. However, issue associated is still critical. Because existing designs have mainly relied on parametric studies, method needed that considers complex factors influencing performance reconstruction and can be generalized for various patients. The goal this study prop...

A test of the accuracy in transferring the virtual data into the surgical environment was carried out. Differences between the virtually planned and the actual position during surgery of the rapid prototyped guides and the bone plates were investigated. The accuracy of the method was evaluated in terms of the precision of cuts in the mandible, the final positions of the rami and condyles, and t...

The purpose of this study was to histologically and mechanically investigate the in vivo bone-bonding ability of anodically oxidized titanium (AO Ti) with an anatase crystal layer on its surface. AO Ti plates, anodically oxidized at 155 V in 1 M H2SO4, were implanted into the proximal metaphyses of mature rabbit tibiae for 4, 8, 16, and 24 weeks and investigated by light microscopy, scanning el...

BACKGROUND The study has been performed to investigate the influence of pulsed magnetic field on the bone growth plates to get new grounds of magneto therapy in AIS treatment. MATERIALS AND METHODS Were used methods of "strong" and "weak" pulsed magnetic fields influence. RESULTS Application of pulsed magnetic field causes an authentic inhibition of chondrocytes' active proliferation proces...

Cysteine (Cys) is known to exert various effects, such as antioxidant, antipancreatitic and antidiabetic effects. However, the effects of Cys on longitudinal bone growth have not been elucidate to date. Thus, the aim of the present study was to evaluate the effects of Cys on bone growth. Growth-plate thickness and bone parameters, such as bone volume/tissue volume (BV/TV), trabecular thickness ...

Laser-Induced Structuring In article number 2201802, Lamborghini Sotelo, Silke Christiansen, and co-workers demonstrate Periodic Surface Structures (LIPSS) for a one-step micro nano surface structuring of different surfaces; however, their formation process still presents an open problem. This study explores the influence initial roughness metal plates on LIPSS. The generated structures are the...

This paper deals with 21 species of Hishimonus Ishihara and two species of Litura Knight from the Indian subcontinent. The following new species are described: Hishimonus acuminatus sp. nov. (India: Mizoram), H. distinctus sp. nov. (India: Karnataka, Kerala, Tamil Nadu. Sri Lanka), H. dwipae sp. nov. (Sri Lanka), H. longisetosus sp. nov. (India: Karnataka), H. spicans sp. nov. (India: Karnataka...
