Let f be a nonconstant meromorphic function in the plane and h be a nonconstant elliptic function. We show that if all zeros of f are multiple except finitely many and T（r, h） = 0{T（r, f）} as r → ∞, then f′ = h... 详细信息

Nanosphere molecularly imprinted polymers doped with gold nanoparticles for high selectivity molecular sensors

引用

Nano Research 2017年第3期10卷 1056-1063页

作者： Tehila shahar Tama Sicron Daniel Mandler Institute of Chemistry The Hebrew University of Jerusalem Jerusalem 9190401 Israel

We report the first attempt of using molecularly imprinted polymers （MIPs） in the shape of nanoparticles that were doped with gold nanoparticles （AuNPs） for surface enhanced Raman scattering （SERS）-based sensing of molecular spedes. Specifically, AuNPs doped molecularly imprinted nano-spheres （AuNPs@nanoMIPs） were synthesized by one-pot precipitation polymerization using Sudan IV as the template for the SERS sensing. The AuNPs@nanoMIPs were characterized by various modes of scanning transmission electron microscopy （STEM） that showed the exact location of the AuNPs inside the MIP particles. The effects of Au concentration and solution stirring on the shape and the polydispersity of the particles were studied. Significant enhancement of the Raman signals was observed only when the MIP particles were doped with the AuNPs. The SERS signal improved significantly with increase in the Au concentration inside the AuNPs@nanoMIPs. Selectivity measurements of the Sudan IV imprinted AuNPs@nanoMIPs carried out with different Sudan derivatives showed high selectivity of the AuNPs-doped MIP particles.

Let F be a family of functions holomorphic on a domain D C C. Let k ≥ 2 be an integer and let h be a holomorphic function on D, all of whose zeros have multiplicity at most k- 1, such that h（z） has no common zeros with any f∈F. Assume also that the following two conditions hold for every f ∈F ：（a） f（z） = 0 == f （z） = h（z）; and （b） y（z） = h（z） == ｜f（k）（z）｜ ≤ c, where c is a *** F is normal on D.

Given a sequence {fn } of meromorphic functions on a plane domain D, there exists a (possibly empty) open set U■D and a subsequence {f n k } which converges uniformly (with respect to the spherical metric on ) on compact subsets of U, while no subsequence of {f n k } converges uniformly on compact subsets of any larger open subset of D.

Since the introduction of nanotechnology, nanoscale materials have developed rapidly and have been applied in various fields including in the pharmaceutical industry, medicine, and tissue engineering. Among a variety of nanomaterials, magnetic iron oxide nanoparticles （IONPs） have been intensively investigated for numerous in vivo applications such as gene and drug delivery, diagnostics, cell labeling and sorting. Compared to nanoparticles made from other materials, IONPs have several additional unique applications due to their magnetic properties, for example, magnetic cell separation,

Ig G4-related disease is a recently recognized entity linked initially to autoimmune pancreatitis and has been subsequently described in nearly every organ system. Men over the age of 50 represent the most affected demographic group and a comprehensive set of diagnostic criteria has been developed to aid treating clinicians. Though elevated levels of Ig G4 in the serum are suggestive of the disease, definitive diagnosis is made on histopathology. Treatment is tailored to the clinical presentation with corticosteroid therapy known to have proven efficacy. Gastric manifestations of the Ig G4-related disease primarily come in two varieties, notably chronic ulceration or pseudotumor formation. Autoimmune pancreatitis conveys increased risk for Ig G4-related disease of the stomach, which is independent of Helicobacter pylori status. In this case report, we present an acute gastric-pericardial fistula secondary to Ig G4-related disease that required urgent operative management. To our knowledge, this is the first report in the medical literature describing this complication of Ig G4-related disease.
