© CCH. Background: Lumbar spine disc breakdown may begin as early as the second decade of life. Peak bone mass occurs between the ages of 16 and 25 years and continuously decreases thereafter where bone loss occurs at a faster rate in females increasing throughout menopause. The objectives of this study were to examine the relationship of age and gender against lumbar or non-lumbar musculoskeletal disorder (MSD) diagnosis and post-injury recovery time. Methods: Records of 144 MSD-related incidents that were recorded between 2012 and 2016 (five years) were retrieved from the injury register of a large commercial cleaning organisation (n = 700 cleaners) for analysis. The mean age of the organisations workforce was 57 years of age and 62% of cleaners were female by payroll. Results: The overall non-lumbar related MSD was higher within the older age ( > 45 years) group (n = 53) as opposed to the younger age ( < 45 years) group (n = 34). Consequently, more lumbar spinerelated MSDs occurred in the younger age ( < 45 years) group (n = 33) than the older age ( > 45 years) group (n = 24). A strong relationship was identified between the age of a cleaner (greater than or less than 45 years) and the type of MSD (lumbar or non-lumbar) (p = 0.027). It was identified that that 110 (76.38%) of cleaners recovered from their MSD within four weeks. Of those in the younger age ( < 45 years) group then 16.42% (n = 11) took longer than four weeks to recover. Of those in the older age ( > 45 years) group then 29.87% (n = 23) took longer than four weeks to recover. A relationship between age and recovery time was identified at the 90% confidence interval (p = 0.058). Conclusions: It was identified that non-lumbar musculoskeletal injury is more likely to occur as one ages. Furthermore, it was identified that age may have an adverse effect upon injury recovery time. It was recommended that manual handling, return to work training programs and work schedules be periodically reviewed to st...

Artificial recognition of facial expression has attracted a lot of attention in the last few years and different facial expression detection methods have been developed. The current study uses a feature point tracking technique separately applied to the five facial image regions (eyebrows, eyes and mouth) to capture basic emotions. The used dataset contains a total 60 facial images from subjects different genders and nationality not wearing glasses and/or facial hair. Results show that the used point tracking algorithm separately applied to the five facial image regions can detect emotions in image sequences.

Introduction: It has been widely assumed that osteoclasts play a pivotal role during the entire process of fracture healing. Bisphosphonates (Bps) are anti-catabolic agents commonly used to treat metabolic bone diseases including osteoporosis, minimizing

Activated protein C (APC) is a serine protease that plays a central role in physiological anticoagulation, and has more recently been shown to be a potent anti-inflammatory mediator. Using cultured human cells, we show here that APC up-regulates the angi

Early expression of p53 protein in thermal burns of guinea pig skin has been reported. This study sought to determine if expression occurred in thermal burns of human skin and if immunohistochemical demonstration of p53 protein could be utilised to distinguish ante-mortem from post-mortem injuries as well as indicating the age of a lesion in the living subject. Biopsy samples were obtained from live patients and post-mortem examinations. Immunohistochemistry was used to demonstrate the presence of p53 protein. Staining was assessed by field counting of epithelial cell nuclei. In live subjects there was a tendency for early (six hour to five day) expression, with peak levels occurring around one to two days. Late samples (13 to 23 days) demonstrated minimal or no expression. In contrast, burn wounds from post-mortem examination demonstrated greater staining for p53 protein in the late (28 to 77 day) samples than in the early ones. It appears that expression of p53 protein may assist in the ageing of ante-mortem, but not post-mortem, burn wounds. This implies that results obtained from live subjects may not be applicable to post-mortem material and that any putative method for determining the age of a wound should be tested in both situations.
