اثر کمبود روی بر رشد، مقدار رنگیزه‌ها و فتوسنتز گیاه کلم قرمز (Brassica oleracea L. var. capitata f. rubra) در سه شرایط نوری متفاوت، شامل 100، 200 و 400 µmolm-2s-1 در محیط هیدروپونیک با غلظت کافی (725 پیکومول روی آزاد) و پایین (30 پیکومول روی آزاد) مطالعه شد. تولید ماده خشک اندام هوایی و ریشه در شرایط کمبود روی به ترتیب تا 95 % و 63 % کاهش، ولی تحت تأثیر افزایش شدت روشنایی افزایش یافت. کمبود رو...
An efficient and highly stereoselective synthesis of D-ribo-(2S,3S,4R)-phytosphingosine was accomplished in 62% overall yield starting from commercially available (2S)-hydroxymethylaziridine via osmium-catalyzed asymmetric dihydroxylation as a key step.
A sample of 3.79 million ψ(2S) events is used to study the decays of charmonium to axialvector plus pseudoscalar mesons. The branching fraction for the decay ψ(2S) → b±1 (1235)π agrees with expectations based on scaling the corresponding J/ψ branching fraction. Flavor-SU(3)-violating K1(1270)K1(1400) asymmetries with opposite character for ψ(2S) and J/ψ decays are observed. This contrasting beh...
Iron-sulfur cluster biogenesis is executed by distinct protein assembly systems. Mammals have two systems, the mitochondrial Fe-S cluster assembly system (ISC) and the cytosolic assembly system (CIA), that are connected by an unknown mechanism. The human members of the NEET family of 2Fe-2S proteins, nutrient-deprivation autophagy factor-1 (NAF-1) and mitoNEET (mNT), are located at the interfac...
To understand translational capacity on a genome-wide scale across three developmental stages of immature soybean seed cotyledons, ribosome profiling was performed in combination with RNA sequencing and cluster analysis. Transcripts representing 216 unique genes demonstrated a higher level of translational activity in at least one stage by exhibiting higher translational efficiencies (TEs) in w...
The pharmacological effects on the central nervous system (CNS) of a range of available flavonoid glycosides were explored and compared to those of the glycosides 2S-hesperidin and linarin, recently isolated from valeriana. The glycosides 2S-neohesperidin, 2S-naringin, diosmin, gossipyn and rutin exerted a depressant action on the CNS of mice following i.p. injection, similar to that found with...
The rates for magnetic dipole (M1) transitions Υ(nS) → ηb(n S) + γ, n ≤ n, are compared. The photon energies for allowed (n = n) M1 transitions are very small, so hindered (n < n) transitions could be more favorable for discovering the ηb(1S, 2S). The question then arises whether Υ(2S) or Υ(3S) is a better source of ηb(1S). Whereas one nonrelativistic model favors ηb(1S) production from Υ(2S), ...
Along with a growing interest in mRNA-based gene therapies, efforts are increasingly focused on reaching the full translational potential of mRNA, as a major obstacle for in vivo applications is sufficient expression of exogenously delivered mRNA. One method to overcome this limitation is chemically modifying the 7-methylguanosine cap at the 5' end of mRNA (m7Gppp-RNA). We report a novel class ...
