Incarcerated gravid uterus liberated by vaginal gauze packing under general anesthesia: a case report.

Incarceration of the gravid uterus is a rare and serious obstetric complication that can lead to severe complications. We present the case of a 32-year-old woman (gravida 5, para 2022) at 12 weeks and 5 days of gestation who presented with urinary retention and lower abdominal pain.

Phenylboronic Acid-Functionalized Ratiometric Surface-Enhanced Raman Scattering Nanoprobe for Selective Tracking of Hg and CHHg in Aqueous Media and Living Cells.

The development of appropriate molecular tools to monitor different mercury speciation, especially CHHg, in living organisms is attractive because its persistent accumulation and toxicity are very harmful to human health.

Unexpected chirality transition and inversion mediated by dissolution-aggregation and the odd-even effect.

The evolution of hierarchical chirality at macromolecular and supramolecular levels in biological systems is ubiquitous; however, achieving precise control over transitions between them in polymer systems is still challenging. Here, we reported multiple chiroptical transitions and inversion phenomena in side-chain azobenzene (Azo) polymers, PAzo-l/d- ( = 3, 6, 7, 8, 9, and 10, where is the total number of atoms from the chiral stereocenter to the Azo unit), with different distances from the chiral stereocenter to the Azo unit. In the case of = 3, an unexpected macromolecular-to-supramolecular chirality transition and inversion occurred when the Azo-polymer underwent from a macromolecular-dissolved state to a supramolecular-aggregated state.

Morphology engineering and photothermal effect derived from perylene diimide based derivative for boosting photocatalytic hydrogen evolution of ZnInS.

The construction of excellent photocatalysts for splitting water into hydrogen is highly desirable to realize carbon neutralization. In this work, an innovative and well-designed S-scheme photocatalyst composed of ultrathin ZnInS (ZIS) nanosheets uniformly anchored on the surface of organic semiconductor PDIIM is successfully fabricated. Within the heterojunction, perylene diimide with an imidazole group (PDIIM) is strategically applied as a structure template, which plays a crucial role in optimizing the morphology, increasing the active sites of sulfur vacancies, providing the additional photothermal effect, and promoting photogenerated charge separation of the catalyst.

Combined Analysis of BSA-Seq Based Mapping, RNA-Seq, and Metabolomic Unraveled Candidate Genes Associated with Panicle Grain Number in Rice ( L.).

Rice grain yield is a complex and highly variable quantitative trait consisting of several key components, including the grain weight, the effective panicles per unit area, and the grain number per panicle (GNPP). The GNPP is a significant contributor to grain yield controlled by multiple genes (QTL) and is crucial for improvement. Attempts have been made to find genes for this trait, which has always been a challenging and arduous task through conventional methods.

Increased precipitation and nitrogen addition accelerate the temporal increase in soil respiration during 8-year old-field grassland succession.

Ecological succession after disturbance plays a vital role in influencing ecosystem structure and functioning. However, how global change factors regulate ecosystem carbon (C) cycling in successional plant communities remains largely elusive.

Chiral Expression and Morphology Control in Polymer Dispersion Systems.

The chiral self-assembly of polymers in dispersions plays an important role in chiral chemistry and self-assembly. In general, both polymerization-induced self-assembly (PISA) and post-polymerization self-assembly can be used to prepare polymer nanoassemblies. In chirality induction or transfer processes, the self-assembly manner of the polymers greatly affects the chiral expression of the nanostructure and cannot be ignored in the chiral fields.

Protein bodies (PBs), the major protein storage organelle in maize (Zea mays) endosperm, comprise zeins and numerous nonzein proteins (NZPs). Unlike zeins, how NZPs accumulate in PBs remains unclear. We characterized a maize miniature kernel mutant, mn*, that produces small kernels and is embryo-lethal.

Controlling the Multiple Chiroptical Inversion in Biphasic Liquid-Crystalline Polymers.

While controlling the chirality and modulating the helicity is a challenging task, it attracts great research interest for gaining a better understanding of the origin of chirality in nature. Herein, structurally similar azobenzene (Azo) vinyl monomers were designed in which the alkyl chains comprised the chiral stereocenter with different achiral tail lengths. Combining the synchronous polymerization, supramolecular stacking and self-assembly, the multiple chiroptical inversion of the Azo-polymer supramolecular assemblies can be modulated by the tail length and DP of Azo blocks during in situ polymerization.
