BACKGROUND: The etiology of chronic prostatitis chronic pelvic pain syndrome (CP/CPPS) is still unclear. As no pathological findings exist the diagnosis of CP/CPPS is essentially a diagnosis by exclusion and functional disorders, so-called somatoform disorders play a more important role. Osteopathy treats functional disorders of the musculoskeletal system including all ...

Guanine to inosine (G→I) substitution has often been used to study various properties of nucleic acids. Inosine differs from guanine only by loss of the N2 amino group while both bases have similar electrostatic potentials. Therefore, G→I substitution appears to be optimally suited to probe structural and thermodynamics effects of ...

Visible light irradiation of a ruthenium(II) quinone-containing complex, [(phen)(2)Ru(phendione)](2+) (1(2+)), where phendione = 1,10-phenanthroline-5,6-dione, leads to DNA cleavage in an oxygen independent manner. A combination of NMR analyses, transient absorption spectroscopy, and fluorescence measurements in water and acetonitrile reveal that complex 1(2+) must be hydrated at the quinone functionality, giving ...

Whilst the interplay between type 2 diabetes and cardiovascular disease (CVD) has been recognised for many years, recent analyses of existing studies have helped refine several aspects of this relationship with relevance to clinical practice. First, recent data demonstrate that fasting glucose is not linearly related to CVD risk in ...

Eukaryotic structural maintenance of chromosomes (SMC)-kleisin complexes form large, ring-shaped assemblies that promote accurate chromosome segregation. Their asymmetric structural core comprises SMC heterodimers that associate with both ends of a kleisin subunit. However, prokaryotic condensin Smc-ScpAB is composed of symmetric Smc homodimers associated with the kleisin ScpA in a postulated ...

A new Bi(3)Ge(3)O(10.5) compound has been synthesized under high pressure, P = 7 GPa, and 700 °C. Instead of the pyrochlore that is normally stabilized under high pressure, the Bi(3)Ge(3)O(10.5) crystallizes in a KSbO(3)-ype crystal structure. The crystal structure has been refined by the Rietveld method from synchrotron X-ray diffraction ...

Ripening of tomato fruits is triggered by the plant hormone ethylene, but its effect is restricted by an unknown developmental cue to mature fruits containing viable seeds. To determine whether this cue involves epigenetic remodeling, we expose tomatoes to the methyltransferase inhibitor 5-azacytidine and find that they ripen prematurely. We ...

Aging has independently been associated with regional brain atrophy, reduced slow wave activity (SWA) during non-rapid eye movement (NREM) sleep and impaired long-term retention of episodic memories. However, whether the interaction of these factors represents a neuropatholgical pathway associated with cognitive decline in later life remains unknown. We found that ...

The formulation of the second-order perturbation approach to the stabilization energy of the A-B interacting species due to charge transfer is revisited. Intrinsic (i.e., electronic) theoretical indices for both relative electrophilicity and nucleophilicity are proposed for any electrophile (A) - nucleophile (B) pairs of combining species. Using the new descriptors, ...

To date, a number of biomolecule-mediated nanoparticle self-assembly systems have been developed that are amenable to controllable disassembly under relatively gentle conditions. However, for some applications such as design of self-assembled multifunctional theragnostic agents, high stability of the assembled structures can be of primary importance. Here, we report extraordinarily high ...

Successful invaders often become established in new ranges by outcompeting native species. The "evolution of increased competitive ability" hypothesis predicts that invasive species are subjected to less predation and parasitization than sympatric native species, and thus can allocate resources from defence and immunity to growth and fecundity, thereby achieving higher ...
