AIM： TO investigate whether this might be related to the presence of hyperhomocysteinemia. METHODS： From January 1998 to December 2008, we evaluated the presence of hyperhomocysteinemia in a series of 165 adult celiac disease （CD） patients （138 females and 27 males, mean age 43 years）.RESULTS： Hyperhomocysteinemia was evident in 32 patients （19.3%）, although most of them had moderate levels （mean value 25 mcg/ml; range 15-30）. Only one patient had a history of myocardial infarction （heterozygosis for N5-N10-metil tetrahydrofolate reductase mutation）. CONCLUSION： The systematic assessment of hyperhomocysteinemia seems, at present, unjustified in CD patients.

Alzheimer's disease(AD) is a progressive neurodegenerative disease histologically characterized by the presence of extraneuronal plaques,mainly formed by the 42-aminoacid isoform of amyloid-(Aβ_(1-42)),and by intraneuronal neurofibrillary to ngles,mainly formed by the tau protein and its hyperphosphorylated isoforms(p-tau).AD is the most common cause of dementia,with an estimated lifetime risk of about 1 in 10 for men and 1 in 5 for women.

There was a long history of releasing various monocrystalline semiconductor structures from their hosting substrates to form“freestanding”structures,in order to change the substrates and for other special *** release was achieved by breaking the bonds between the film and the substrate,through methods such as forming interfacial gas bubbles(“smart-cut”technology for fabricating semiconductor-on-insulator wafers)or chemical etching(selectively etching epitaxial AlAs underlayer for fabricating GaAs-on-silicon photonic devices).The exfoliation of layered van der Waals materials in recent decades also produced another class of freestanding monocrystalline materials—twodimensional(2D)*** addition to changeable substrates,being freestanding also allowed unique methods to manipulate the 2D materials;for example,transferring them on flexible substrates and directly stretching them controls the strain in their lattice,as well as their strain-dependent physical properties.
