Leg extensor muscle strength, postural stability, and fear of falling after a 2-month home exercise program in women with severe knee joint osteoarthritis.

BACKGROUND AND OBJECTIVE. The aim of this study was to compare the leg extensor muscle strength, the postural stability, and the fear of falling in the women with severe knee joint osteoarthritis (OA) before and after a 2-month home exercise program (HEP). MATERIAL AND METHODS.

The spiral glenohumeral ligament: an open and arthroscopic anatomy study.

Purpose: The purpose of this study was to visualize arthroscopically and to describe the micro- and macroscopic anatomy of the poorly known ligament of the anterior capsule of the glenohumeral joint: the so-called ligamentum glenohumerale spirale (spiral GHL).

Methods: Twenty-two fresh shoulder joints were dissected, and the anatomy of the anterior capsular structures (the spiral GHL, the middle glenohumeral ligament [MGHL], and the anterior band as well as the axillary part of the inferior glenohumeral ligament [AIGHL and AxIGHL, respectively]) was investigated. For arthroscopic visualization, 30 prospective arthroscopic clinical cases and 19 retrospective video clips of the patients who had an arthroscopic shoulder procedure with a normal subscapularis tendon, labrum, and anterior joint capsule were evaluated.

Altered mitochondrial apparent affinity for ADP and impaired function of mitochondrial creatine kinase in gluteus medius of patients with hip osteoarthritis.

The cellular energy metabolism in human musculus gluteus medius (MGM) under normal conditions and hip osteoarthritis (OA) was explored. The functions of oxidative phosphorylation and energy transport systems were analyzed in permeabilized (skinned) muscle fibers by oxygraphy, in relation to myosin heavy chain (MHC) isoform distribution profile analyzed by SDS-PAGE, and to creatine kinase (CK) and adenylate kinase (AK) activities measured spectrophotometrically in the intact muscle. The results revealed high apparent Km for ADP in regulation of respiration that decreased after addition of creatine in MGM of traumatic patients (controls).

Extensive limb lengthening in Ollier's disease: 25-year follow-up.

A case of extensive lower limb lengthening (32 cm) in a 14-year-old male patient with Ollier's disease is reported. A varus deformity of the femur and a valgus deformity of the tibia were evident. The femur was successfully lengthened 22 cm by metaphyseal distraction, and the tibia was lengthened 10 cm by two-stage distraction-compression method with a cylindrical bone allograft.

Transport proteins in rats' renal corpuscle and tubules.

Unlabelled: The localization of transepithelial transport proteins for glucose and water reabsorption in renal corpuscle and tubules epithelium was observed.

Material And Methods: Immunohistochemistry of normal male Wistar rats' kidney has been performed. Facilitated diffusion glucose transporter GLUT4, Na(+)-dependent glucose co-transporter SGLT1, a cargo transporter TGN38, and water transporter aquaporin-2 (AQP2) were used.

Bone status in healthy Estonian women assessed with quantitative ultrasonometry.

We assessed age-related changes of bone status in healthy Estonian women in various age groups with quantitative ultrasonometry. The speed of sound (SOS), broadband ultrasound attenuation (BUA), and stiffness index (SI) of the calcaneus were measured in 288 women. BUA and SI values peaked at 30-39 years of age while SOS peaked at 20-29 years and decreased thereafter.
