A cluster of two psittacosis cases among women farmers exposed to Chlamydia psittaci-infected domestic poultry in Zhejiang Province, China.

A cluster of Chlamydia psittaci (C. psittaci) cases was reported in Zhejiang Province, China, 2019. This study evaluates the extent of the outbreak and determines the source of infection.

Hybrid Zeolitic Imidazolate Frameworks for Promoting Electrocatalytic Oxygen Evolution via a Dual-Site Relay Mechanism.

Developing efficient oxygen evolution reaction (OER) electrocatalysts is important for enhancing the water splitting efficiency. However, with the current catalysts containing one kind of active sites, it is challenging to achieve low overpotentials because of the four-electron transfer process. Herein is reported HZIF-2-CoMo, a new metal-organic framework with well-defined Co-Mo dual sites that can promote the OER process through an unconventional Mo/Co dual-site relay mechanism.

Analysis of dose-effect relationship between DVH parameters and clinical prognosis of definitive radio(chemo)therapy combined with intracavitary/interstitial brachytherapy in patients with locally advanced cervical cancer: A single-center retrospective study.

Purpose: The purpose of the study was to explore the dose-effect relationship between dose-volume histogram parameters and clinical prognosis of definitive radio(chemo)therapy followed by intracavitary/interstitial brachytherapy in locally advanced cervical cancer.

Methods And Materials: A retrospective analysis was performed on 110 patients with locally advanced cervical cancer who underwent external beam radiotherapy combined with intracavitary/interstitial brachytherapy with or without chemotherapy from July 2010 to September 2018. We reported D, D, and D for high-risk clinical target volume (HR-CTV) and intermediate-risk clinical target volume, D for organs at risk.

An -like factor is associated with the origin of two domesticated varieties in (Orchidaceae).

has been artificially domesticated for centuries in Asia, which produced numerous cultivated varieties. Flowers with stamenoid tepals or those with multiple tepals have been found in different species of ; however, the molecular basis controlling the formation of these phenotypes is still largely unknown. Previous work demonstrated that lineage MADS genes function in floral meristem determinacy as well as in reproductive organs development in both dicots and monocots, indicating a possible relationship with the origin of two flower varieties in .

Transcriptome-Wide Analysis Reveals the Origin of Peloria in Chinese Cymbidium (Cymbidium sinense).

An orchid flower exhibits a zygomorphic corolla with a well-differentiated labellum. In Cymbidium sinense, many varieties with peloric or pseudopeloric flowers have been bred during centuries of domestication. However, little is known about the molecular basis controlling orchid floral zygomorphy and the origin of these varieties.

NH Be BO F and γ-Be BO F: Overcoming the Layering Habit in KBe BO F for the Next-Generation Deep-Ultraviolet Nonlinear Optical Materials.

KBe BO F (KBBF) is still the only practically usable crystal that can generate deep-ultraviolet (DUV) coherent light by direct second harmonic generation (SHG). However, applications are hindered by layering, leading to difficulty in the growth of thick crystals and compromised mechanical integrity. Despite efforts, it is still a great challenge to discover new nonlinear optical (NLO) materials that overcome the layering while keeping the DUV SHG available.

Construction of unprecedented pillar-layered metal organic frameworks via a dual-ligand strategy for dye degradation.

A dual-ligand strategy is used to construct two pillar-layered metal organic frameworks (MOFs) with [Zn(COO)] subunits (SBUs) and [ZnCo(ethanol)(COO)] SBUs, respectively. Remarkably, the Zn/Co mixed compound 2 exhibits excellent and adjustable photocatalytic activity to degrade crystal violet (CV) in water under visible light.

Collaborative enhancement from Pb and F in Pb(NO)(HO)F generates the largest second harmonic generation effect among nitrates.

The first metal nitrate fluoride nonlinear optical material, Pb(NO)(HO)F, was synthesized with the largest second harmonic generation (SHG) effect (12 × KHPO) among nitrates. Theoretical calculations revealed the synergistic effect of [NO], lone pair electrons in Pb, and F for the SHG effect. The F also promoted the blue-shift of the ultraviolet cut-off edge.

Diverse tetrahedral tetrazolate frameworks with N-rich surface.

Three tetrahedral tetrazolate frameworks (TTFs) with SOD, and topologies (TTF-4, -5 and -6) are obtained by using the anion and solvent as structure-directing agents. The resulting SOD-type TTF-4 shows high chemical stability as well as high CO2 uptake capacity.

Achievement of Bulky Homochirality in Zeolitic Imidazolate-Related Frameworks.

Before this work, adding chiral C centers into zeolitic imidazolate frameworks (ZIFs) has never been realized. Presented here are the first examples on achieving bulky homochirality in ZIF systems, and three homochiral zeolitic imidazolate-related frameworks with sodalite and dia topologies are successfully synthesized by employing enantiopure imidazolate derivatives. The results open a new blueprint on the synthetic design of homochiral ZIFs for future applications.
