Tubular lipid binding proteins (TULIPs) have become a focus of interest in the cell biology of lipid signalling, lipid traffic and membrane contact sites. Each tubular domain has an internal pocket with a hydrophobic lining that can bind a hydrophobic molecule such as a lipid. This allows TULIP proteins to carry lipids through the aqueous phase. TULIP domains were first found in a large family ...

a measured MarT of 9.4 °C. Carbon isotopes of T. giganteus were ambiguous and reveal no significant relationships with trends in nutrient concentrations (n and P), dissolved oxygen, and dissolved organic carbon, although they did exhibit more negative values concomitant with landfall of Hurricane Irene and trended to increasing values with ontogeny that could reflect migration. Carbon isotopes ...

In 1859 Charles Darwin published his theory of evolution in his book On the Origin of Species. The theory actually consisted of two distinct parts: First, species are descended from other, earlier species. There is currently no scientific disagreement with this part. The second part concerned the way evolution works. Survival of the fittest was an elegant yet simple explanation for the mechanic...

Two principled decisions underlay the introduction of the new compulsory medical humanities course. First, it was decided, all lecturers must be trained in the discipline; second, the course content must be relevant to medicine. This paper gives details of the content of eight selective courses. There is also an example of an essay by one of the students, Tiffany Suk. Entitled "Two patients in ...

For a variety of quenched random spin systems on an Apollonian network, including ferromagnetic and antiferromagnetic bond percolation and the Ising spin glass, we find the persistence of ordered phases up to infinite temperature over the entire range of disorder. We develop a renormalization-group technique that yields highly detailed information, including the exact distributions of local mag...

OBJECTIVES This prospective study was undertaken to evaluate the effects of transurethral ultrasound-guided laser-induced prostatectomy (TULIP) on urodynamic, symptomatic, and prostate volume parameters as well as serum prostate-specific antigen. METHODS The TULIP procedure was performed in 33 patients with benign prostatic hyperplasia with a mean age of 66 years. Patients were evaluated by p...
