BACKGROUND: Although the occupational health field has identified psychosocial factors as risk factors for low back pain that causes disability, the association between disabling low back pain and psychosocial factors has not been examined adequately in Japanese hospital workers. Therefore, this study examined the association between low back pain, which interfered with work, and psychosocial factors in Japanese hospital workers. METHOD: This cross-sectional study was conducted at a hospital in Japan...

Microgravity as well as chronic muscle disuse are two causes of low back pain originated at least in part from paraspinal muscle deconditioning. At present no study investigated the complexity of the molecular changes in human or mouse paraspinal muscles exposed to microgravity. The aim of this study was to evaluate longissimus dorsi adaptation to microgravity at both morphological and global gene expression level. C57BL/N6 male mice were flown aboard the BION-M1 biosatellite for 30 days (BF) or housed in a replicate flight habitat on ground (BG)...

During the flight of birds, it is often possible to notice that some of the primaries and covert feathers on the upper side of the wing pop-up under critical flight conditions, such as the landing approach or when stalking their prey (see Fig. 1) . It is often conjectured that the feathers pop up plays an aerodynamic role by limiting the spread of flow separation . A combined experimental and numerical study was conducted to shed some light on the physical mechanism determining the feathers self actuation and their effective role in controlling the flow field in nominally stalled conditions...

The skin is the most requested product of ratite slaughter and 'first-rate' ratite's skin has a high economic market. Ostrich hide is tanned in South Africa and sold all over the world. Besides, the ostrich meat is considered a niche production in the marketplace, thus allowing for another pro t for the ostrich breeding. Theorical analysis of skinning process has been carried out, and an automatic measurement system has been designed to record the drawing-force on the animal's body during skinning tests. The aim of this study was to indentify the best animal position and provide values of drawing-force in order to design a speci c machine for ostrich skinning...

BACKGROUND: People with low back pain exhibit altered postural coordination that has been suggested as a target for treatment, but heterogeneous presentation has rendered it difficult to identify appropriate candidates and protocols for such treatments. This study evaluated the associations of task-related and person-related factors with the effect of low back pain on anticipatory postural adjustments. METHODS: Thirteen subjects with and 13 without low back pain performed seated, rapid arm flexion in self-initiated and cued conditions...

The Howieson's Poort (HP; ∼65-59 ka) continues to be a source of interest to scholars studying human behavioral evolution during the Late Pleistocene. This is in large part because the HP preserves evidence for a suite of innovative technologies and behaviors (including geometric backed tools and engraved ostrich eggshell), but also because the disappearance of the innovative behaviors associated with this phase is not well understood. Here, I present taphonomic and taxonomic data on the full sample of macromammal remains excavated from the HP deposits at Sibudu Cave under the direction of Lyn Wadley...

The prevalence of chronic low back pain (CLBP) is increasing. Treatment is effective in less than 50% of patients after 1 year. This review investigates new treatments for CLBP. An extensive literature review focuses on new treatments for CLBP. Their safety and efficacy were evaluated and are described in detail in this review. The investigation identified new treatments for CLBP including chemonucleolysis, platelet-rich plasma injections, artemin, tanezumab, and stem cells. Further research and innovation are needed to implement these methods into practice and assess clinical significance...

PURPOSE: Mild depression has been shown as a precursor and as a consequence of low back pain, even in early phases of acute or subacute pain. Chronic daily life stress as well as dysfunctional pain-related cognitions such as thought suppression (TS) seem to play a role in the pain-depression cycle; however, the mechanisms of these associations are less understood. Experimentally induced TS, conceived as the attempt to directly suppress sensations such as pain, has been shown to paradoxically cause a delayed and non-volitional return of the suppressed thoughts and sensations and to increase affective distress...

With its low work function and high mechanical strength, the LaB6/VB2 eutectic system is an interesting candidate for high performance thermionic emitters. For the development of device applications, it is important to understand the origin, value, and spatial distribution of the work function in this system. Here we combine thermal emission electron microscopy and low energy electron microscopy with Auger electron spectroscopy and physical vapor deposition of the constituent elements to explore physical and chemical conditions governing the work function of these surfaces...

BACKGROUND AND IMPORTANCE: Tarlov cysts, also known as perineural cysts, have been described as meningeal dilations of the spinal nerve root sheath between the peri- and endoneurium at the dorsal root ganglion. Most often they are found in the sacrum involving the nerve roots. Normally asymptomatic, they have been reported to present with radiculopathy, paresthesias, and even urinary or bowel dysfunction. Sacral insufficiency has not been a well-documented presentation. CLINICAL PRESENTATION: The patient is a 38-year-old female who started to develop left low back pain and buttock pain that rapidly progressed into severe pain with some radiation down the posterior aspect of her left leg...

Older adults are largely under-represented in to LBP research. In light of the ageing population, it is crucial to understand the influence of comorbidities and lifestyle factors on the risk and prognosis of LBP in older adults. The aims of this study were to describe the course of LBP in older men; to investigate if comorbidities/ lifestyle factors can predict the course of LBP in older men; to assess if comorbidities/ lifestyle factors increase the risk of developing LBP in older men. The study sample comprised 1,685 older men living in suburban Sydney, Australia...

Functional and nutritional soluble proteins can be recovered from surimi (and surimi-like material) processing wastewater, reducing environmental problems and the cost of an irresponsible waste disposal. Recovered proteins may be added back at a low percentage to surimi products. The aim of this work was to evaluate the effect of the addition of soluble recovered proteins (RP), obtained from mechanically separated chicken meat surimi-like material (MSCM-SLM) processing wastewater by acidic pH-shifting, on the composition and texture of RP-MSCM-SLM, with RP contents of 0, 10, 20 and 30% (w/w) in the mixture...

The aim was to compare the physical characteristics of under-18 academy and schoolboy rugby union competition by position (forwards and backs). Using a microsensor unit, match characteristics were recorded in 66 players. Locomotor characteristics were assessed by maximum sprint speed (MSS) and total, walking, jogging, striding and sprinting distances. The slow component (<2 m · s(-1)) of PlayerLoad(TM) (PLslow), which is the accumulated accelerations from the three axes of movement, was analysed as a measure of low-speed activity (e...

Background Computed tomography (CT) of the left atrium (LA) is performed prior to pulmonary vein isolation (PVI) to improve success of circumferential ablation for atrial fibrillation. The ablation procedure itself exposes patients to substantial radiation doses, therefore radiation dose reduction in pre-ablational imaging is of concern. Purpose To assess and compare diagnostic performance of low-radiation dose preprocedural CT in patients scheduled for PVI using two types of reconstruction algorithms. Material and Methods Forty-six patients (61 ± 10 years) scheduled for PVI were enrolled in this study irrespective of body-mass-index or cardiac rhythm at examination...
