Skin cancers are the most common form of malignant neoplasms in man. In this work, near-infrared Fourier transform (NIR-FT) Raman spectroscopy was used to study the molecular alterations in the most common skin cancer, basal cell carcinoma (BCC). Biopsies from 16 histopathologically veriÐed BCC and 16 biopsies from normal skin were harvested and analysed by NIR-FT-Raman spectroscopy using a 106...

Conflicting views of circum-Pacific tectonics have focused on the PhilippinesTaiwan region, where there has been neither convincing documentation nor general agreement on the importance of transcurrent (strike-slip) faulting or the possible sense of regional horizontal displacement. Structural and physiographic features of the 1200-km-long Philippine fault zone are fully as spectacular as those...

intervertebral joints, with contusion of the cord by the neural arch at the moment of injury, and that spontaneous reduction accounted for the subsequent normal radiographic appearances. This theory was criticised by Cramer and McGowan (1944), and Barnes (1948) showed that a posterior dislocation in flexion that was capable of spontaneous reduction did not produce sufficient narrowing of the sp...

We report here a structural study of $R\mathrm{Ba}{\mathrm{Mn}}_{2}{\mathrm{O}}_{6}$ ($R=\mathrm{La}$, Pr, and Nd) compounds by means synchrotron radiation x-ray powder diffraction Raman spectroscopy. The three are $A$-site ordered perovskites adopting the prototypical tetragonal structure at high temperature. A ferromagnetic transition is observed in $\mathrm{LaBa}{\mathrm{Mn}}_{2}{\mathrm{O}}...

The photophysics of multiple resonance thermally activated delayed fluorescence molecule ?-DABNA is described. We show coupling a 285 cm–1 stretching/scissoring vibrational mode peripheral phenyl rings to the S1 state, which dictates ultimate emission full-width at half maximum. However, separate high amplitude mode, 945 N-biphenyl units, mediates reverse intersystem crossing (rISC) mechanism. ...

tone is functionally as resistance to passive movement. it is separated into postural tone and phasic tone. phasic tone is the result of rapid stretching of a tendon and the muscle spindle, however postural tone is the result of a steady, restrained strech on muscles. hypottonia is a decreased resistance to passive movement. the term floppy is frequently used to describe hypotonic children. in ...

Interlaminar fracture mechanics has proven useful for characterizing the onset of delaminations in composites and has been used with limited success primarily to investigate onset in fracture toughness specimens and laboratory size coupon type specimens. Future acceptance of the methodology by industry and certification authorities however, requires the successful demonstration of the methodolo...

Metacarpal fractures are common injuries in pediatric patients. In adults, cannulated intramedullary screws an excellent stabilization option for metacarpal and widely used, but patients with open physes, their use is a relative contraindication. The risk of injury to the physis classic retrograde screw placement makes this type osteosynthesis not option. We present case 8-year-old patient two ...
