PURPOSE To assess bone density of kneecaps in subjects with femoro-tibial prosthesis before and after surgery by means of DEXA examination. SUBJECTS AND METHODS We examined 34 patients with unilateral femoro-tibial prosthesis, 20 healthy subjects of the same age and non-carriers of knee replacement and 14 healthy young adult subjects. All the data sets were analysed by two radiologists (AS an...

Chronic elevations in circulating angiotensin II (AngII) levels produce sustained hypertension and increased intrarenal AngII contents through multiple mechanisms, which may include sustained or increased local production of AngII. This study was designed to test the hypothesis that chronic AngII infusion increases renal angiotensinogen mRNA and protein levels, thus contributing to the increase...

Abstract Background In the present study, an HPTLC (high-performance thin-layer chromatography) method was developed for quantitative determination and validation of curcumin in methanolic fraction Curcuma longa L . For achieving good separation curcumin, mobile phase chloroform:methanol (97:3) used. The densitometric analysis performed at 420 nm reflection/absorption mode. Results Linearity ob...

OBJECTIVE To investigate various cerebrospinal fluid (CSF) markers that could assist in the clinical diagnosis of Creutzfeldt-Jakob disease (CJD). METHODS CSF samples were analysed for the presence of 14-3-3 protein, microtubule associated protein tau, and beta amyloid in 250 patients with possible CJD. Densitometric analysis was used to quantify the level of 14-3-3 in all patients. RESULTS...

patients and methods in this cross-sectional study, we evaluated all patients referred to a single rheumatology clinic for bone mineral density measurements from 2009 to 2010. all patients who had bone mineral density measurements taken from the hip, lumbar spine, forearm, and whole body were enrolled in the study. standard bone mineral density measurements were performed using a dual energy x-...

BACKGROUND Computer tomography (CT) densitometry is a potential tool for detecting the progression of emphysema but the optimum methodology is uncertain. The level of inspiration affects reproducibility but the ability to adjust for this variable is facilitated by whole lung scanning methods. However, emphysema is frequently localised to sub-regions of the lung and targeted densitometric sampli...

This perspective paper presents a hypothesis that links abnormalities of bone material with densitometric findings in two congenital metabolic bone disorders, osteogenesis imperfecta type I (OI) and X-linked hypophosphatemic rickets (XLH). Analyses of iliac bone samples from OI patients have shown that material bone density is elevated and that the bone material is abnormally stiff in this diso...

OBJECTIVE This study investigated the effects of low-level laser therapy (LLLT) and electrical stimulation (ES) on bone loss in spinal cord-injured rats. MATERIALS AND METHODS Thirty-seven male Wistar rats were divided into four groups: standard control group (CG); spinal cord-injured control (SC); spinal cord-injured treated with laser (SCL; GaAlAs, 830 nm, CW, 30 mW/cm, 250 J/cm(2)); and sp...

BACKGROUND We investigated the levels of transcription factors associated with activation of the mitogen-activated protein (MAP) kinase pathway in schizophrenics using postmortem brain samples. These studies were done to determine whether our previous findings of abnormal levels of the MAP kinases in the cerebellar vermis were linked to additional downstream targets of this signal transduction ...

BACKGROUND Bone metabolism assessment requires the determination of bone mass and quality. The bone metabolism was assessed with the modified bone scintigraphy using 99mTc-MDP. The elaboration of radioisotopic method and program allowed for the assessment of bone metabolism, index of bone metabolism assay and definition of its normal values range with the possibility of clinical application. ...
