Blanchetia heterotricha is a species popularly used for its medicinal properties. However, few scientific records report the investigation of its chemical composition and biological activity. Herein, a metabolomics and multivariate statistical analysis approach was used to assess the chemical composition, antioxidant, and antimicrobial activity of B.

Antimicrobial films were prepared with chitosan containing the methanolic extract of M. tenuiflora leaves (FECT20 %, FECT30 %, and FECT40 %), and their antimicrobial activities were evaluated by agar diffusion. The films were characterized by IR spectroscopy, scanning electron microscopy (SEM) and TG/DTG curves.

Osteogenesis imperfecta (OI) type VI is a rare inherited disorder of the connective tissue caused by pathogenic variants in SERPINF1 gene, which encodes the pigment epithelium-derived factor (PEDF). PEDF is implicated in many biologic processes, including an anti-cancer role. This information is supported by in vitro and in vivo studies that evidenced its anti-angiogenic, anti-tumorigenic, and anti-metastatic properties.

The effects of vitamin D on the musculoskeletal system are well established. Its deficiency causes osteomalacia, secondary hyperparathyroidism, and an increased risk for fractures and falls. However, clinical and experimental evidence points to extra-skeletal actions of vitamin D, including on immune and respiratory systems.

Background: The objective of this study was to determine whether individuals with hip osteoarthritis who undergo THA have higher HRQOL scores than those awaiting the procedure; An additional aim was to investigate associated factors exerting an impact on HRQOL.

Materials And Methods: A cross-sectional study was conducted. Participants were divided into two groups: pre-THA and post-THA.

Glutathione S-transferase (GST) participates in the biotransformation of many xenobiotics including biocides. Its activity in plants is generally associated with their phytoremediation capabilities. Biocides have been used in agriculture and antifouling paints and they represent risks for the aquatic environment.

The aim of this study was to verify the effects of a high-intensity jump-based aquatic exercise (HIIAE) program on bone mass and functional fitness in postmenopausal women. We randomly assigned 25 women (65 ± 7 years) into two groups: Training group (T, n = 15) and Untrained group (Un, n = 10). The T group was submitted to 24 weeks of HIIAE program, where each session lasted for 30 minutes.

Physical exercise is an important stimulus for osteoporosis prevention and treatment. However, it is not clear yet which modality would be better to stimulate bone metabolism and enhance physical function of postmenopausal women. This review paper aims to summarize and update present knowledge on the effects of different kinds of aquatic and ground physical exercises on bone metabolism and physical function of postmenopausal women.

Aim: The aim of this study was to investigate the impact of circuit-based exercise on the body composition in obese older women by focusing on physical exercise and body weight (BW) gain control in older people.

Methods: Seventy older women (>60 years old) voluntarily took part in the study. Participants were randomized into six different groups according to body mass index (BMI): appropriate weight (AW) control (AWC) and trained (AWT) groups, overweight (OW) control (OWC) and trained (OWT) groups, and obesity (O) control (OC) and trained (OT) groups.

Objectives: The aim of this study was to determine the precision of the measurements of 2 craniometric anatomic points--glabella and anterior nasal spine--in order to verify their possibility as potential locations for placing implants aimed at nasal prostheses retention.

Methods: Twenty-six dry human skulls were scanned in a high-resolution spiral tomography with 1-mm axial slice thickness and 1-mm interval reconstruction using a bone tissue filter. Images obtained were stored and transferred to an independent workstation containing e-film imaging software.

The wavelet packet transform (WPT) is a variant of the standard wavelet transform that offers greater flexibility in the decomposition of instrumental signals. Although encouraging results have been published concerning the use of WPT for signal compression and denoising, its application in multivariate calibration problems has received comparatively little attention, with very few contributions reported in the literature. This paper presents an investigation concerning the use of WPT as a feature extraction tool to improve the prediction ability of PLS models.
