5-Nitrouracil and 5-nitrouridine derivatives which C-2 and C-4 oxo-groups of the pyrimidine base were replaced by thio groups were synthesized. The lipophilicities of thiopyrimidine bases were enhanced significantly as indicated by P-values. Oxygen-sulfur exchange leading to 2-thiouracil (2) and 2,4-dithiouracil (3) were associated with 1.4- and 2.6-fold increase in P-value relative to that of uracil (1). The P-values of 5-nitro-2-thiouracil (5) and 5-nitro-2,4-dithiouracil (6) were increased 13.2- and 79.8-fold relative to that of 5-nitrouracil (4). Most of the 5-nitrothiopyrimidine bases and their nucleosides were found to be moderately active against Staphylococcus aureus and Escherichia coli except 5-nitrouracil (4).
Be x Mg 1− x O ultra-thin dielectric films, deposited via super-cycle ALD and controlled sub-cycle ratio, show a POT of 3.7 nm, an EOT of 1.3 nm, and low leakage current, suitable for dynamic random access memory.

The microhardness and the structural characteristics of the chemically vapor deposited TiN film on the 430 stainless steel substrate have been investigated with various deposition parameters such as the deposition time, the total flow rate, the flow rate ratio , and the deposition temperature. The most important factor to affect the microhardness of the TiN film in this study was the denseness of the structure in connection with the degree of the lattice strain. The relationship between the lattice parameter changes and the grain size variation under all deposition conditions generally followed the grain boundary relaxation model. The (111) preferred orientation prevailed in the early stage of the deposition conditions, however, the (200) preferred orientation was developed in the later stage. The surface morphology at optimum conditions displayed a dense diamond shaped structure and the microhardness of the films was high (1700-2400Hv) regardless of the type of the substrates used.

Purpose: The purpose of this study was to analyze the macular vessel density layer-by-layer and compare the diagnostic value of each in diagnosing glaucoma. Methods: This was a prospective comparative cross-sectional study, and the setting was glaucoma referral practice. The study participants were patients with primary open-angle glaucoma undergoing treatment with drugs, and age-matched normal controls who visited our clinic for regular eye examinations for refractive errors. All participants were investigated using macular optical coherence tomographic angiography, fundus photography, and 24-2 visual field (VF) testing. Average vessel densities in the retinal nerve fiber–ganglion cell–inner plexiform layer (IPL), retinal nerve fiber–ganglion cell layer (GCL), retinal nerve fiber layer (RNFL), ganglion cell–IPL, GCL, and IPL segments on optical coherence tomographic angiography. Results: Fifty-eight glaucomatous eyes of 58 participants and 52 healthy eyes of 52 normal subjects were included in the study. The average vessel densities of all segments, except the RNFL in the glaucoma group, were significantly lower than that in normal subjects. The average vessel density in the ganglion cell–IPL showed the highest correlation with the mean deviation and VF index of the VF (r = 0.515 and 0.538, respectively) and the best area under receiver operating characteristic curve to discriminate between patients with glaucoma and patients with normal eyes (0.750). Conclusions: The present study demonstrated that macular vessel density in the ganglion cell–IPL has a higher diagnostic ability and better correlation with functional damage in glaucoma than that in the superficial vascular plexus. Translational Relevance: These findings suggest that the macular vessel density in the ganglion cell–inner plexiform layer is better than that in the conventional superficial vascular plexus for detecting glaucoma.
