The literature and our present examinations indicate that the intra-leaf light absorption profile is in most cases steeper than the photosynthetic capacity profile. In strong white light, therefore, the quantum yield of photosynthesis would be lower in the upper chloroplasts, located near the illuminated surface, than that in the lower chloroplasts. Because green light can penetrate further int...

A retinally stabilized object readily undergoes perceptual fading. It is commonly believed that the color of the apparently vanished object is Wlled in with the color of the background because the features of the Wlled-in area are determined by features located outside the stabilized boundary. Crane, H. D., & Piantanida, T. P. (1983) (On seeing reddish green and yellowish blue. Science, 221, 10...

A retinally stabilized object readily undergoes perceptual fading. It is commonly believed that the color of the apparently vanished object is filled in with the color of the background because the features of the filled-in area are determined by features located outside the stabilized boundary. Crane, H. D., & Piantanida, T. P. (1983) (On seeing reddish green and yellowish blue. Science, 221, ...

OBJECTIVE In synovial fluid (SF) from patients with rheumatoid arthritis (RA), neutrophils are exposed to proinflammatory mediators endowed with either anti-apoptotic or pro-apoptotic properties. We investigated neutrophil apoptosis in the presence of SF from 11 RA patients. METHODS SF was obtained from affected knees of 11 patients with RA. Human neutrophil apoptosis was evaluated by light m...

The most widely used gene editing technology-the CRISPR/Cas9 system-employs a bacterial monomeric DNA endonuclease known as clustered regularly interspaced short palindromic repeats (CRISPR)-associated protein 9 (Cas9) and single-guide RNA (sgRNA) that directs Cas9 to a complementary target DNA. However, introducing mutations into higher polyploid plant species, especially for species without g...

A study concerned with the effects of iron on chlorophyll, acidity, ascorbic acid, and carbohydrate fractions of Ananas comosus was reported in a previous publication (35). Also, the effects of different amounts of potassium on growth and ash constituents of the same plants were reported in a former paper of this series (36). This study is concerned with the effects of potassium on chlorophyll,...

Femtosecond (fs)-laser hyperdoped silicon has aroused great interest for applications in infrared photodetectors due to its special properties. Crystallinity and optical absorption influenced by co-hyperdoped nitrogen in surface microstructured silicon, prepared by fs-laser irradiation in gas mixture of SF₆/NF₃ and SF₆/N₂ were investigated. In both gas mixtures, nitrogen and sulfur were incorpo...

The aim of this study was to evaluate whether DQ could prove useful to identify monosodium urate (MSU) and calcium pyrophosphate dehydrate (CPPD) crystals on permanent mounted stained slides. To this end, we studied 27 synovial fluid (SF) samples obtained from the knees of patients with the pseudogout (n=21) and acute gouty arthritis (n=6). Wet analysis for crystal detection and identification ...
