Introduction: Phthalates exposure is a major public health concern due to the accumulation in the environment and associated with levels of testosterone reduction, leading to adverse pregnancy outcomes. However, the relationship between phthalate-induced testosterone level decline and ferroptosis remains poorly defined.

Objectives: Herein, we aimed to explore the mechanisms of phthalates-induced testosterone synthesis disorder and its relationship to ferroptosis.

High-intensity interval training alleviates exhaustive exercise-induced HSP70-assisted selective autophagy in skeletal muscle.

This study was designed to probe the effect of chaperone-assisted selective autophagy (CASA) on the maintenance of proteostasis during exhaustive exercise and uncover the alteration of CASA in muscle fibers with pre-high-intensity interval training (HIIT) intervention-induced muscle adaptation in response to exhaustive exercise. Rats were randomly divided into a control group; an exhaustive exercise group; and an HIIT + exhaustive exercise group. Results show myofibril damage and BiP levels were increased after exhaustive exercise, and the levels of the HSP70, BAG3, ubiquitin, autophagy-related proteins, and their interactions were increased.

We systematically introduced the origin and development of green space equity, explored its multidimensional progress in conceptual connotation, measurement methodology, phenomenon, mechanism, and regulation, and proposed the enlightenment for deepening the related studies. The green space equity originated from environmental social movement and environmental justice studies, and experienced multilevel evolution in topic constriction and theoretical interpretation.

Thermal necrosis in orthopedic bone tumors: experimental research.

Introduction: The extent of surgical resection in orthopedic oncology differs according to tumor biology. While malignant bone tumors are operatively managed with wide resection, benign bone tumors and metastatic carcinomas are often treated through intralesional excision and adjuvant modalities, including the elimination of residual neoplastic cells through thermal necrosis. This study investigates in vitro temperature thresholds for thermal necrosis in common orthopedic bone tumors.

Design and Synthesis of Red Through-Space Charge Transfer Thermally Activated Delayed Fluorescence Emitters with Donor/Acceptor/Donor Stacking.

Red through-space charge transfer thermally activated delayed fluorescence (TSCT TADF) materials named SAF36DCPP and SAF27DCPP with sandwiched structures were synthesized. Single crystals indicated that the intramolecular C-H···π interactions play a vital role in rigidifying the sandwiched structure, which results in a fluorescence yield of 63% for SAF36DCPP compared to 40% for SAF27DCPP. Organic light-emitting diodes with SAF36DCPP as the emitter realized a maximum external quantum efficiency of 16.

Ion-Dipole Interaction Enabling Highly Efficient CsPbI Perovskite Indoor Photovoltaics.

Metal halide perovskites are ideal candidates for indoor photovoltaics (IPVs) because of their easy-to-adjust bandgaps, which can be designed to cover the spectrum of any artificial light source. However, the serious non-radiative carrier recombination under low light illumination restrains the application of perovskite-based IPVs (PIPVs). Herein, polar molecules of amino naphthalene sulfonates are employed to functionalize the TiO substrate, anchoring the CsPbI perovskite crystal grains with a strong ion-dipole interaction between the molecule-level polar interlayer and the ionic perovskite film.

In Situ Inorganic Ligand Replenishment Enables Bandgap Stability in Mixed-Halide Perovskite Quantum Dot Solids.

Instability in mixed-halide perovskites (MHPs) is a key issue limiting perovskite solar cells and light-emitting diodes (LEDs). One form of instability arises during the processing of MHP quantum dots using an antisolvent to precipitate and purify the dots forming surface traps that lead to decreased luminescence, compromised colloidal stability, and emission broadening. Here, the introduction of inorganic ligands in the antisolvents used in dot purification is reported in order to overcome this problem.

Triplet excitons can be utilized upon introduction of phosphors into exciplexes, and such a scenario has been studied in the development of high-performance near-infrared (NIR) organic light-emitting diodes (OLEDs). To generate exciplexes in an emitting layer (EML) in the device, commercially available phosphors bis(2-phenylpyridinato-N,C')iridium(acetylacetonate) [Ir(ppy)acac] and iridium(III) bis(4-phenylthieno[3,2-]pyridinato-N,C')acetylacetonate (PO-01) were selected as donor components; in addition, a new designed fluorescent molecule, 3-([1,1':3',1″-terphenyl]-5'-yl)acenaphtho[1,2-]quinoxaline-9,10-dicarbonitrile (AQDC-tPh), and recently reported 3-([1,1':3',1″-terphenyl]-5'-yl)acenaphtho[1,2-]pyrazine-8,9-dicarbonitrile (APDC-tPh) were selected as acceptor components. An OLED with PO-01:AQDC-tPh blends as the EML has realized NIR emission at 750 nm and a maximum external quantum efficiency (EQE) of >0.

Switching of Enantioselectivity in the Cu-Catalyzed Asymmetric Decarboxylative Aldol Reaction of Tryptanthrin with Keto Acids: An Unexpected Counteranion Effect.

Cu-bisoxazoline-catalyzed enantioselective decarboxylative aldol reaction of tryptanthrin with aryl-substituted keto acids is developed, providing a straightforward approach to deliver a series of phaitanthrin A analogues. Both enantiomers of the products can be obtained with good to high enantioselectivity in the presence of a single chiral ligand by simply changing the copper salts. Based on the X-ray crystallographic analysis of chiral Cu(II)-bisoxazoline complexes, the tentative stereochemical models are presented to account for the observed counteranion-induced switching in enantioselectivity.

[Effect of electroacupuncture on morphine-conditioned place preference and activation of glutamatergic neurons in the ventromedial prefrontal cortex in rats].

Objective: To observe the effect of electroacupuncture (EA) at "Zusanli"(ST36) and "Sanyinjiao"(SP6) on conditioned place preference (CPP) and activation of glutamatergic neurons in the ventromedial prefrontal cortex (VMPFC) of morphine-addiction rats, so as to explore its mechanisms underlying detoxification.

Methods: Thirty male SD rats were randomly and equally divided into control, model and EA groups. The rats with acquisition of morphine-induced CPP received intraperitoneal injection of morphine (10 mg/kg) in the morphine-paired chamber, once daily for 3 consecutive days, and those of the control group received intraperitoneal injection of the same dose of normal saline in saline-paired chamber.

Multi-Layer π-Stacked Molecules as Efficient Thermally Activated Delayed Fluorescence Emitters.

Multi-layer π-stacked emitters based on spatially confined donor/acceptor/donor (D/A/D) patterns have been developed to achieve high-efficiency thermally activated delayed fluorescence (TADF). In this case, dual donor moieties and a single acceptor moiety are introduced to form two three-dimensional (3D) emitters, DM-BD1 and DM-BD2, which rely on spatial charge transfer (CT). Owing to the enforced face-to-face D/A/D pattern, effective CT interactions are realized, which lead to high photoluminescence quantum yields (PLQYs) of 94.

The effect of increased family finance and dual-parental absence since infancy on Children's cognitive Abilities.

Existing research suggests that parental absence per se does not have a main effect on children's cognitive development. However, this body of research is confounded by decreased family finance resulted from parental absence. Further insights on children's cognitive development can be gained by studying situations where parental absence actually leads to higher family finance.
