Facilitated pain mechanisms have been demonstrated in musculoskeletal pain but it is unclear whether a recent painful injury leaves the pain system sensitized. Pain characteristics were assessed in individuals who recently recovered from ankle pain (recovered pain group; n=25) and sex-matched controls (n=25) in response to tonic-pressure pain and saline-induced pain applied at the shin muscle. Pain intensity and pain referral patterns were recorded bilaterally after the painful muscle stimulus. Pressure pain thresholds (PPTs) were measured at the lower legs and shoulder...

Substantial over-diagnosis and under-diagnosis of asthma in adults and children has recently been reported. As asthma is mostly diagnosed in non-specialist settings, a clinical prediction model (CPM) to aid the diagnosis of asthma in primary care may help improve diagnostic accuracy. We aim to systematically identify, describe, compare, and synthesise existing CPMs designed to support the diagnosis of asthma in children and adults presenting with symptoms suggestive of the disease, in primary care settings or equivalent populations...

Abnormal endogenous pain modulation (EPM) was suggested as a potential mechanism for chronic pain, i.e., increased pain facilitation and/or impaired pain inhibition underlying symptoms manifestation. EPM function can be tested using psychophysical methods such as temporal summation of pain (TSP) and conditioned pain modulation (CPM), which assess pain facilitation and inhibition, respectively. Several studies have investigated EPM function in patients with non-paroxysmal orofacial pain (OFP) and reported mixed results...

Poultry manure (PM), a rich source for crop nutrients, is produced in ample quantities worldwide. It provides necessary nutrient to soil and has a potential to improve plant water holding availability under semiarid environment. The effect of composted poultry manure (CPM) and irrigation regimes on morpho-physiology of selective maize (Zea mays L.) hybrids (H1 = drought tolerant, H2 = drought sensitive) was investigated in this study. Two field experiments were conducted during 2010 and 2011 under randomized complete block design with split split-plot arrangements and three replications of each treatment...

Valproic acid (VPA) has been reported to inhibit cancer cell growth and has therapeutic use in retinal diseases. However, the mechanism of this action remains unclear. In order to explore this mechanism, primary human retinal pigment epithelial (hRPE) cell cultures were established. Cell viability was assessed by the trypan blue exclusion method (T), and the cell proliferation was measured by 3 H-thymidine incorporation (3H-thy). P38 synthesis was quantitated by using 14C-methionine-labeled P38 (14C-P38) by using P38-specific antibody...

Maximal anaerobic exercise, is a short high intensity effort, involves activation of the hypothalamus-pituitary-adrenal axis, and may suggest hypoalgesic effects. In addition, this exercise-induced muscle pain may contribute to hypoalgesia via the pain inhibits pain phenomenon, which is related to the diffuse noxious inhibitory control (DNIC) mechanism. We aimed to investigate whether: 1) a single bout of 30 s maximal anaerobic exercise has an analgesic effect on experimental pain sensitivity; 2) DNIC is the underlying mechanism of anaerobic exercise-induced hypoalgesia (EIH)...

In porous materials, metal sites with coordinate solvents offer opportunities for many applications, especially those promoted by host-guest chemistry, but such sites are especially hard to create for Li-based materials, because unlike transition metals, lithium does not usually possess a high-enough coordination number for both framework construction and guest binding. This challenge is addressed by mimicking the functional group ratio and metal-to-ligand charge ratio in MOF-74. A family of rod-packing lithium-organic frameworks (CPM-47, CPM-48, and CPM-49) were obtained...

BACKGROUND: Accurate risk adjustment is the key to a reliable comparison of cost and quality performance among providers and hospitals. However, the existing case-mix algorithms based on age, sex, and diagnoses can only explain up to 50 percent of the cost variation. More accurate risk adjustment is desired for provider performance assessment and improvement. OBJECTIVE: To develop a case-mix algorithm that hospitals and payers can use to measure and compare cost and quality performance of their providers...

Well-differentiated (WD) liposarcoma is a low-grade mesenchymal tumor with features of mature adipocytes and high propensity for local recurrence. Often, WD patients present with or later progress to a higher-grade nonlipogenic form known as dedifferentiated (DD) liposarcoma. These DD tumors behave more aggressively and can metastasize. Both WD and DD liposarcomas harbor neochromosomes formed from amplifications and rearrangements of Chr 12q that encode oncogenes ( MDM2 , CDK4 , and YEATS2) and adipocytic differentiation factors ( HMGA2 and CPM) However, genomic changes associated with progression from WD to DD have not been well-defined...
