Context: Acupressure and halogen light stimulation, are used to reduce false non-reactive nonstress test results related to fetal sleep.
Objective: This study was conducted to determine the effect of acupressure and halogen light stimulation on nonstress testing and anxiety during pregnancy.
Design: Randomized controlled experimental study.
Setting: The population of the study consisted of pregnant women who were requested to have a nonstress test.
Participants: The sample of the study included 132 pregnant women (acupressure group:44; halogen light group:45, and control group:43).
Methods: The acupressure group was applied acupressure on the Zhiyin acupuncture point three times, the halogen light group was applied halogen light stimulation twice on the fetal head from the mother's abdomen. In the interpretation of the results, the level of statistical significance was taken as P < 0.05.
Main Outcome Participants: In our study, there was no difference between the acupressure and halogen light groups in terms of the mean number of fetal movements, the number of accelerations, the time to the first acceleration, and the time to reach the reactive result in the nonstress test (P > 0.05), while the mean number of fetal movements and accelerations of these two groups were higher, and the mean time to the first acceleration and the mean time to reach the reactive result in the nonstress test were shorter than those of the control group (P < 0.05). In addition, no statistically significant difference was found between the groups in terms of mean state anxiety inventory scores (P > 0.05).
Results: Acupressure and halogen light stimulation increased the rates of reactive nonstress tests.

Flavin-dependent halogenases (FDHs) are promising candidates for the sustainable production of halogenated organic molecules by biocatalysis. FDHs require only oxygen, halide and a fully reduced flavin adenine dinucleotide (FADH) cofactor to generate the reactive HOX that diffuses 10 Å to the substrate binding pocket and enables regioselective oxidative halogenation. A key challenge for the application of FDHs is the regeneration of the FADH.

Dion-Jacobson (DJ) perovskites are promising alternatives for Ruddlesden-Popper (RP) perovskites to fabricate blue perovskite light-emitting diodes (PeLEDs) due to their favorable structural and charge properties. However, the relatively weak hydrogen bond between the bridging diammonium group and perovskite poses huge challenges for regulating crystallization and defect density, leading to an undesirable film quality and device performance. Herein, we report the successful optimization of DJ perovskite films by introducing a new type of cesium octafluoroadipate (CsOFAA) precursor, which could strongly anchor the perovskite through coordination bonds and halogen-halogen bonds.

An efficient visible-light-induced radical carbon oximation of styrenes with 1-nitrosopyrrolidine and organic halides is developed. The reaction proceeds smoothly in the absence of a transition metal and a photocatalyst under mild conditions, producing a wide range of functionalized oximes in moderate to good yields. Mechanistic studies reveal that the reaction involves the generation of nucleophilic α-amino alkyl radicals and subsequent halogen atom transfer (XAT) with organic halides.

One of the goals in synthetic chemistry is to obtain compounds featuring unusual valence states that are stable under ambient conditions. At present, stabilizing unusual Pt(III) states is considered difficult, except through direct Pt-Pt bonding such as that in platinum-blues or organometallization using bulky ligands. Pt(III) stabilization is also very difficult in halogen-bridged metal complex chains (MX-Chains).

While charge-transfer complexes involving halogen-bonding interactions have emerged as an alternative strategy for the photogeneration of carbon radicals, examples using (fluoro)alkyl bromides are limited. This report describes a dual catalytic approach for radical generation from α-bromodifluoroesters and amides under visible-light irradiation. Mechanistic studies suggest that the reaction proceeds through bromide displacement using a catalytic iodide salt, generating a C-I bond that can be engaged by our halogen-bonding photocatalysis platform.
