Automated 3D breast ultrasound (ABUS) is a new popular modality as an adjunct to mammography for detecting cancers in women with dense breasts. In this paper, a multi-stage computer aided detection system is proposed to detect cancers in ABUS images. In the first step, an efficient despeckling method called OBNLM is applied on the images to reduce speckle noise. Afterwards, a new algorithm based on isocontours is applied to detect initial candidates as the boundary of masses is hypo echoic. To reduce false generated isocontours, features such as hypoechoicity, roundness, area and contour strength are used...

BACKGROUND: Call-center operators are exposed to working conditions that indicate an increased risk of developing musculoskeletal disorders. Nevertheless, there are few studies regarding health and working condition in call-center operators. Thus, this study was designed to investigate the physical activity levels and prevalence of low back pain (LBP) in Thai call-center operators. MATERIALS AND METHODS: A self-reported questionnaire was distributed to 150 operators at a call center to identify the physical activity levels, prevalence of LBP, personal characteristics, and associated work factors...

BACKGROUND: Low back pain (LBP) is one of the most common health problems in adults. The impact of LBP on the individual can cause loss of health status and function related to pain in the back. To reduce the impact of LBP on adults, drug therapy is the most frequently recommended intervention. But over the last decade, a substantial number of randomized clinical trials of non-pharmacological intervention for LBP have been published. OBJECTIVE: To determine the effectiveness of acupuncture, acupressure and chiropractic (non-pharmacological) interventions on the treatment of chronic nonspecific low back pain in Iran...

Haoxiang Li, Gang Hua
Pose variation remains to be a major challenge for real-world face recognition. We approach this problem through a probabilistic elastic part model. We extract local descriptors (e.g., LBP or SIFT) from densely sampled multi-scale image patches. By augmenting each descriptor with its location, a Gaussian mixture model (GMM) is trained to capture the spatial-appearance distribution of the face parts of all face images in the training corpus, namely the probabilistic elastic part (PEP) model. Each mixture component of the GMM is confined to be a spherical Gaussian to balance the influence of the appearance and the location terms, which naturally defines a part...

Low back pain (LBP) is one of the major disabling health conditions among older adults aged 60 years or older. While most causes of LBP among older adults are non-specific and self-limiting, seniors are prone to develop certain LBP pathologies and/or chronic LBP given their age-related physical and psychosocial changes. Unfortunately, no review has previously summarized/discussed various factors that may affect the effective LBP management among older adults. Accordingly, the objectives of the current narrative review were to comprehensively summarize common causes and risk factors (modifiable and non-modifiable) of developing severe/chronic LBP in older adults, to highlight specific issues in assessing and treating seniors with LBP, and to discuss future research directions...

BACKGROUND: The involvement of inflammatory components in the pathophysiology of low back pain is poorly understood. It has been suggested that spinal manipulative therapy (SMT) may exert anti-inflammatory effects. PURPOSE: To determine the involvement of inflammation-associated chemokines (CC series) in the pathogenesis of non-specific low back pain and to evaluate the effect of SMT on that process. METHODS: Patients presenting with non-radicular, non-specific low back pain (minimum pain score 3 on 10 point visual analogue scale, VAS) were recruited according to stringent inclusion criteria...

Sleep problems are common in people with low back pain (LBP), however the mechanisms on how sleep influences pain are complex. To date there is a lack of prospective research on the timings and the development of sleep problems in those who have LBP, such information would be useful to identify individuals at risk of poor outcome. Aims are to investigate the predictive role of sleep problems on self-report recovery and pain intensity using logistic regression reporting Odds Ratios (OR). An observational cohort of 761 chronic LBP patients recruited from a pain management clinic participated, and completed data at baseline, and at 6 month follow-up (n = 682)...

The translocation of a lipid binding protein (LBP) is studied using a phenomenological coarse-grained computational model that simplifies both chain and pore geometry. We investigated via molecular dynamics the interplay between transport and unfolding in the presence of a nanopore whose section oscillates periodically in time with a frequency ω, a motion often referred to as the radial breathing mode (RBM). We found that the LPB when mechanically pulled into the vibrating nanopore exhibits a translocation dynamics that in some frequency range is accelerated and shows a frequency locking to the pore dynamics...

BACKGROUND CONTEXT: Non-steroidal anti-inflammatory (NSAID) agents are a widely utilized treatment for low back pain (LBP). Literature on NSAID use in articular cartilage has shown detrimental effects; however, minimal data exist to detail the effects of NSAIDs in intervertebral disc degeneration (IDD). As IDD is a major cause of LBP, we explored the effects of indomethacin, a commonly used NSAID, on disc matrix homeostasis in an animal model of IDD. PURPOSE: To determine the effects of oral indomethacin administration on IDD in an in vivo rabbit model...
