Background: Chondromalacia patella is the most common cause of mechanical knee pain in young women. Q angle and knee alignment are important clinical parameters for biomechanics of the patellofemoral joint. Objective: To identify the prevalence of knee malalignment and to find out if there is a correlation between knee mal alignment and Q angle with age at onset of disease. Methods: All pa...

Still-to-video face recognition (FR) is an important function in several video surveillance applications like watchlist screening, where faces captured over a network of video cameras are matched against reference stills belonging to target individuals. Screening of faces against a watchlist is a challenging problem due to variations in capturing conditions (e.g., pose and illumination), to cam...

Question IL-18 is a pro-inflammatory cytokine produced by a variety of myeloid and non-hematopoietic cells. It is canonically associated with enhancing interferon gamma (IFNg) and cytotoxicity in collaboration with IL-12p70, IL-15, or type I IFN. However, in other contexts IL-18 can promote IL-17, IL-22, or allergic responses. Macrophage Activation Syndrome (MAS) is a sepsis-like syndrome that ...

In the centennial anniversary of the discovery of the etiologic agent of Chagas disease (Carlos Chagas discovered the disease, vector and etiologic agent all at once!), the subject is not only current, but the acute disease stills occurs. The vector-transmitted disease is already under control in Brazil, but the congenital and transfusional forms, and those by non-usual transmission, are still ...

An innovative approach to date fiber-based gelatin silver prints using near-infrared spectroscopy (NIR) and multivariate analysis is presented. NIR spectra were acquired for 152 film stills printed in the USA between 1914 and 1986, and partial least square (PLS) analysis was used to correlate the spectra with the year the photographs were printed. Principal component analysis and spectral inter...

This review aims to provide a comprehensive analysis of active solar stills, promising technology for sustainable water purification. Active stills utilize external energy sources and the sun's evaporate condense water, thereby removing impurities producing clean drinking water. However, existing reviews on have certain limitations. addresses these limitations through consistent experimental se...

  Background: Postmenopausal onset rheumatoid arthritis (post-RA) is expected to have greater bone mineral density (BMD) loss than premenopauasal onset (pre-RA) due to estrogen deficiency and aging. This study aimed to compare the BMD status of the two RA groups with age-matched non-RA controls.   Methods: The patients with RA on follow-up examination were stratified according to age of onset. ...

background: there is no documented demographical study on iranian parkinson's disease (pd) patients, so this study was conducted to identify demographic information about patients with pd in iran, and to explore demographical differences between pd patients in iran and other countries. methods: we reviewed medical records of 1656 patients diagnosed with pd, who referred from all parts of iran t...

This paper reports the use of a mathematical model to predict the productivity of a simple solar still under different climatic, design and operational parameters in Oman. The shallow water basin, 23 cover tilt angle, 0.1 m insulation thickness and asphalt coating of the solar still were found to be the optimum design parameters that produced an average annual solar still yield of 4.15 kg/m day...
