AIM: To suggest a novel retinopathy of prematurity(ROP) screening model in developing countries incorporating postnatal weight gain ratios(PWGR) to traditional parameters to maintain sensitivity and improve specificity in detecting ROP. MEthODS: Analysis of weekly PWGR of infants from one tertiary referral center during six months to determine the age at which the PWGR with the highest predictability for ROP development which was referred to as the postnatal net weight gain ratio(NWGR). NWGR was added to conventional criteria to describe a new model(the Alex-ROP model). RESULTS: Of 560 infants were included. NWGR 28 d after birth was the most predictive factor for the development of ROP. A new model Alex-ROP recommending screening infants with gestational age(GA) ≤33 wk or birth weight ≤1500 g and NWGR at 28 d after birth th type 1 and type 2) recommending a cutoff point of NWGR th and 28^(th) day. CONCLUSION: Both Alex-ROP and Hg Alex-ROP models are easy to apply to improve the specificity of ROP screening in developing countries while maintaining high sensitivity.

Let R = ⊙n〉0 Rn be a standard graded ring, a ∩ ⊙n〉0 Rn an ideal of R, and M, N two finitely generated graded R-modules. this paper studies the homogeneous components of graded generalized local cohomology modules. We show that for any i 〉 0, the n-th graded component Hiα（M, N）n of the i-th generalized local cohomology module of M and N with respect to a vanishes for all n 〉〉 0. Some sufficient conditions are pro- posed to satisfy the equality sup{end（Hiα （M, N）） [ i _〉 0} = sup{end（HiR＋（M, N））｜ i 〉 0}. Also, some sufficient conditions are proposed for the tameness of Hiα（M, N） such that i = fRα＋（M,N） or i = cdα（M,g）, where fRα＋（M,N） and cdα（M,g） denote the R＋- finiteness dimension and the cohomological dimension of M and N with respect to a, respectively. Finally, we consider the Artinian property of some submodules and quotient modules of Hjα（M, N）, where j is the first or last non-minimax level of Hiα（M, N）.

Electropolymerized o-phenylenediamine firm is used as a functional coating for the immobilization of anti-S. aureus antibody on the surface of a gold-plated piezoelectric crystal, and this piezoelectric immunosensor is applied to detect S. aureus. the frequency shift (Delta F = F-20s - F-380s, Hz) between the frequency at the 20th second (after the addition of sample, F-20s) and that at 380 seconds later (F-380s) was introduced to construct a calibration graph, and shortening of assay time was achieved. the S. aureus concentrations in the range of 10(5)-10(9) cells/mL can be detected by this system.

the previously derived Lane consistent dispersive coupled-channel optical model for nucleon scattering on 232th and 23Su nuclei is extended to describe scattering on even-even actinides with Z=90-98. A soft-rotator- model （SRM） description of the low-lying nuclear structure is used, where the SRM Hamiltonian parameters are adjusted to the observed collective levels of the target nucleus. SRM nuclear wave functions （mixed in K quantum number） have been used to calculate the coupling matrix elements of the generalized optical model. the ＂effective＂ deformations that define inter-band couplings are derived from the SRM Hamiltonian parameters. Conservation of nuclear volume is enforced by introducing a dynamic monopolar term to the deformed potential, leading to additional couplings between rotational bands. the fitted static deformation parameters are in very good agreement with those derived by Wang and collaborators using the Weizs^cker-Skyrme global mass model （WS4）, allowing use of the latter to predict cross sections for nuclei without experimental data. A good description of the scarce ＂optical＇experimental database is achieved. SRM couplings and volume conservation allow a precise calculation of the compound-nucleus formation cross sections, which is significantly different from that calculated with rigid-rotor potentials coupling the ground-state rotational band. the derived parameters can be used to describe both neutron- and proton-induced reactions.
