TL;DR: Although strength deficits persisted, these deficits did not seem to affect the functional status in this sample of patients and no significant difference was found between the SF-36 scores obtained by the sample compared to the general United States population.
Abstract: Background: A number of operative techniques, including decompression with debridement and flexor hallucis longus (FHL) tendon augmentation, have been described for chronic degenerative Achilles te...

TL;DR: It was concluded that there is no significant difference between the 14 different elements in both Portland cement and MTA.
Abstract: The purpose of this study was to compare the composition of Portland cement and Mineral Trioxide Aggregate (MTA). Samples of MTA and Portland cement were analysed for fifteen different elements by inductively coupled plasma emission spectrometry (ICP-ES). Comparative analysis revealed there was significant similarity except there was no detectable quantity of Bismuth in Portland cement. Quantitative results are given in both parts per million (p.p.m.) and wt%. It was concluded that there is no significant difference between the 14 different elements in both Portland cement and MTA.

TL;DR: Melatonin's role in bone physiology is described and how disruption of melatonin rhythms by light exposure at night, shift work, and disease can adversely impact on bone is discussed.
Abstract: An important role for melatonin in bone formation and restructuring has emerged, and studies demonstrate the multiple mechanisms for these beneficial actions. Statistical analysis shows that even with existing osteoporotic therapies, bone-related disease, and mortality are on the rise, creating a huge financial burden for societies worldwide. These findings suggest that novel alternatives need to be developed to either prevent or reverse bone loss to combat osteoporosis-related fractures. The focus of this review describes melatonin's role in bone physiology and discusses how disruption of melatonin rhythms by light exposure at night, shift work, and disease can adversely impact on bone. The signal transduction mechanisms underlying osteoblast and osteoclast differentiation and coupling with one another are discussed with a focus on how melatonin, through the regulation of RANKL and osteoprotegerin synthesis and release from osteoblasts, can induce osteoblastogenesis while inhibiting osteoclastogenesis. Also, melatonin's free-radical scavenging and antioxidant properties of this indoleamine are discussed as yet an additional mechanism by which melatonin can maintain one's bone health, especially oral health. The clinical use for melatonin in bone-grafting procedures, in reversing bone loss due to osteopenia and osteoporosis, and in managing periodontal disease is discussed.

TL;DR: The results obtained support Kitasato's (1968) proposal that a large passive H+ influx is balanced by an active efflux of this ion.
Abstract: Alternating bands of acid and base formation have been detected along the length of the internodal cell of Nitella clavata when it is illuminated, while in the dark this phenomenon is minimal. Chloride influx occurs only or largely in the acid-extruding regions, and this is also a light-dependent ion movement. Chloride efflux is slightly dependent on illumination and is not localized as are H+ efflux and Cl- influx. The results obtained support Kitasato's (1968) proposal that a large passive H+ influx is balanced by an active efflux of this ion. Transport mechanisms suggested by the correlations of Cl- and HCO3- influxes with H+ extrusion are discussed.

TL;DR: The structural and functional alterations of WM in natural aging are summarized and how age-related WM changes influence the progression of various brain disorders, including ischemic and hemorrhagic stroke, TBI, Alzheimer's disease, and Parkinson's disease are discussed.
