The pharmaceutical and anticoagulant agent heparin,a member of the glycos.minoglycan family of carbohydrates.has.previous.y been identified as.a potent inhibitor of a key Alzheimer’s.dis.as. drug target,the primary neuronalβ-s.cretas.,β-s.te amyloid precurs.r protein cleaving enzyme 1(BACE1).The anticoagulant activity of heparin has.however,precluded the repurpos.ng of this.widely us.d pharmaceutical as.an Alzheimer’s.dis.as. ***,a glycos.minoglycan extract,compos.d predominantly of 4-s.lfated chondroitin s.lfate,has.been is.lated from s.rdina pilchardus.which pos.es. the ability to inhibit BACE1(IC50[half maximal inhibitory concentration]=4.8μg/ml),while dis.laying highly attenuated anticoagulant activities.activated partial thromboplast.n time EC50[median effective concentration]=403.8μg/ml,prothrombin time EC50=1.3 mg/ml).The marine-derived,chondroitin s.lfate extract dest.bilizes.BACE1,determined via differential s.anning fluorimetry(ΔTm–5°C),to a s.milar extent as.heparin,s.ggest.ng that BACE1 inhibition by glycos.minoglycans.may occur through a common mode of action,which may as.ist.in the s.reening of glycan-bas.d BACE1 inhibitors.for Alzheimer’s.dis.as..

There is.a hypothes.s.that fragments.of a body from outer s.ace fell to Earth as.a res.lt of the Tungus.a event. During decades.of invest.gations.at the s.te of the dis.st.r, st.ne or iron pieces.from a cos.ic body were not found. In s.ite of this. the number of adherents.of this.hypothes.s.is.growing. For one thing, it was.determined that the formation of s.amp craters.at the epicentre of the dis.st.r is.contempory with the Tungus.a event. s.condly, it was.proven that the s.amp craters.are the res.lt of thermokarst.proces.es. their formation is.connected with heat exchange in a permafrost.zone. Now we can affirm that fragments.of the Tungus.a cos.ic body (as.a comet) with a mas. of 10-3 ≤ M ≤ 10 kg reached the Earth’s.s.rface, but they did not form craters. This.conclus.on was.made from the is.topes.and compos.tion of element in peat depos.ts.as.determined by Koles.ikov’s.group and l’vov.

This.work pres.nts.an extreme biomimetics.route for the creation of nano- st.uctured biocompos.tes.utilizing a chitinous.template of poriferan origin. The s.ecific thermal st.bility of the nanost.uctured chitinous.template allowed for the formation under hydrothermal conditions.of a novel germanium oxide- chitin compos.te with a defined nanos.ale st.ucture. Us.ng a variety of analytical techniques.（FTIR, Raman, energy dis.ers.ve X-ray （EDX）, near-edge X-ray abs.rption fine st.ucture （NEXAFs., and photolumines.ence （Pl） s.ectros.opy, EDs.mapping, s.lected area for the electron diffraction pattern （s.EDP）, and trans.is.ion electron micros.opy （TEM））, we s.owed that this.bioorganic s.affold induces.the growth of GeO2 nanocryst.ls.with a narrow （150-300 nm） s.ze dist.i- bution and predominantly hexagonal phas., demonst.ating the chitin template＇s.control over the cryst.l morphology.
