A Novel Methacryloyl-Masked NIR Fluorescent Probe for Detection of Cysteine and Its Application in Bioimaging.

Cysteine (Cys) detection is recognized as an essential element in this investigation due to the critical function of Cys in several physiological processes in living organisms. A new NIR fluorescent probe SNC-Cys has been synthesized by incorporating a five-membered malononitrile derivatized ring as an electron withdrawing group, and a methacryloyl group detection moiety for cysteine. After adding Cys, SNC-Cys shows an emission of 654 nm and further works as a "Turn-on" probe via ICT photomechanism.

Does induction or augmentation of labor increase the risk of postpartum hemorrhage in pregnant women with anemia? A multicenter prospective cohort study in India.

Objective: To investigate whether induction/augmentation of labor in pregnant women with anemia increases the risk of postpartum hemorrhage (PPH) and whether this risk varied by indications for labor induction/augmentation and by anemia severity in pregnancy.

Methods: In a prospective cohort study of 9420 pregnant women from 13 hospitals across India, we measured hemoglobin concentrations at recruitment (≥28 weeks of gestation) and blood loss after childbirth during follow-up and collected clinical information about PPH. Clinical obstetric and childbirth information at both visits were extracted from medical records.

Iron Deficiency Anaemia in Pregnancy: A Narrative Review from a Clinical Perspective.

Anaemia in pregnancy is a global problem of significance in all settings. The most common cause is iron deficiency. Large numbers of women are affected, ranging up to 25-30% antenatally and 20-40% postnatally.

A trans-Ferulic acid based fluorescence "turn-on" chemosensor for aluminum (III) ions in live cells and environmental samples.

This study introduces a novel fluorescence 'turn-on' chemosensor, FHDA, based on a trans-Ferulic acid Schiff-base derivative. FHDA stands out as a highly selective and sensitive tool for the fluorescent detection of Al3 with the fluorescence 'turn-on' effect. FHDA exhibits a strong CHEF effect and ICT upon complexation with Al in a 1:2 binding stoichiometry.
