AI Article Synopsis

  • A novel fluorescent sensor called ocn has been created for detecting aluminum ions specifically in a Tris-HCl solution, showing excellent selectivity over other substances.
  • ocn produces a noticeable fluorescence signal at 438 nm when it binds to aluminum, demonstrating a 2:1 binding ratio with a detection limit as low as 0.3 μM.
  • The sensor's effectiveness in biological contexts is confirmed, indicating it can successfully detect aluminum within living cells.

Article Abstract

A novel fluorescent sensor, 1-((2-hydroxynaphthalen-1-yl)methylene)urea (ocn) has been designed and applied as a highly selective and sensitive fluorescent probe for recognition of Al in Tris-HCl (pH = 7.20) solution. The probe ocn exhibits an excellent selectivity to Al over other examined metal ions, anions and amino acids with a prominent fluorescence 'turn-on' at 438 nm. ocn binds to Al with a 2:1 binding stoichiometry and the detection limit was 0.3 μM. Furthermore, its capability of biological application was evaluated and the results showed that the sensor could be used to detect Al in living cells.

A regioselective [3 + 2] annulation of β,γ-alkynyl-α-ketimino esters with 1,3-dicarbonyls is disclosed. A series of -selective dihydrofurans bearing an exocyclic double bond and a quaternary carbon center are accessed without the usage of base. Control and deuterium-labeling experiments have been investigated to probe into the reaction mechanism.

HIV-1 envelope broadly neutralizing antibodies represent a promising component of HIV-1 cure strategies. To evaluate the therapeutic efficacy of combination monoclonal antibodies (mAbs) in a rigorous nonhuman primate model, we tested different combinations of simian immunodeficiency virus (SIV) neutralizing mAbs in SIVmac251-infected rhesus macaques. Antiretroviral therapy-suppressed animals received anti-SIV mAbs targeting multiple Env epitopes spanning analytical treatment interruption (ATI) in 3 groups (n = 7 each): i) no mAb; ii) 4-mAb combination; and iii) 2-mAb combination.

Colon cancer, as a highly prevalent malignant tumor globally, poses a significant threat to human health. In recent years, ferroptosis and cuproptosis, as two novel forms of cell death, have attracted widespread attention for their potential roles in the development and treatment of colon cancer. However, the investigation into the subtypes and their impact on the survival of colon cancer patients remains understudied.

Smallholder wheat farmers of Ethiopia frequently use landraces as seed sources that are low yielders and susceptible to diseases due to shortage of seeds of adapted improved bread wheat varieties. Developing novel improved varieties with wider adaptability and stability is necessary to maximize the productivity of bread wheat. Hence, a multi-location field trial was conducted across four locations in south Ethiopia during the 2022/23 main cropping season with the objective of estimating the magnitude of genotype by environment interaction (GEI) effect, and determine the stable genotype among the 10 Ethiopian bread wheat advanced selections using a randomized complete block design (RCBD) with three replications.

Sweetpotato Stem Rot Nematode () causes the most devastating disease affecting sweetpotato production in China. The objectives of this study were: i) establish a quantification method using real-time PCR for of sweetpotato; ii) analyze the effect of density at harvest on the percentage of disease incidence in sweetpotatoes; and iii) evaluate the effect of soil physical properties on disease incidence. Populations of isolated from 28 different production areas in Henan Province exhibited identical sequences, and then real-time PCR specific primers (PRNf and PRNr) were designed.
