Triple-negative breast cancer (TNBC) poses a major clinical challenge due to its aggressive progression and limited treatment options, making early diagnosis and prognosis critical. MicroRNAs (miRNAs) are crucial post-transcriptional regulators that influence gene expression. In this study, we unveil novel miRNA-mRNA interactions and introduce a prognostic model based on miRNA-target interaction (MTI), integrating miRNA-mRNA regulatory correlation inference and the machine learning method to effectively predict the survival outcomes in TNBC cohorts.

The endoplasmic reticulum-mitochondrial crosstalk involved in nanoplastics and di(2-ethylhexyl) phthalate co-exposure induced the damage to mouse mammary epithelial cells.

With the extensive use of plastic products, significant amounts of microplastics, nanoplastic particles (NPs), and plasticizers such as Di(2-ethylhexyl) phthalate (DEHP) are continuously released into the environment. However, the toxic effects of NPs alone or in combination with DEHP on mammary glands remain unreported. This study investigates the impacts of NPs and DEHP on the structure and function of mouse mammary epithelial cells and elucidates the underlying molecular mechanisms.

A facile approach for synthesizing nitrogen-doped carbon supported circular trough-shaped FeCo alloy for the oxygen reduction reaction.

A nitrogen-doped carbon-supported circular trough-shaped FeCo alloy-based electrocatalyst (FeCo/NC) was synthesized by a simple-to-accomplish method. The unique alloy structure and rich Fe/Co-N-based active sites constructed during the pyrolysis process endowed FeCo/NC with comparable electrocatalytic ORR activity in both a three-electrode system and Zn-air batteries to that of previously reported FeCo alloy-based catalysts.

A Three-layer Tissue-mimicking Phantom for Radiofrequency Skin Treatment.

Tissue-mimicking phantoms (TMPs) have been widely used to simulate human tissues in the pre-clinical study. However, the electrothermal properties of the existing radiofrequency (RF) TMPs cannot satisfy the RF heating for skin treatment and may lead to the inaccuracy thermal distribution. In order to improve the accuracy of thermal distribution caused by RF fields in the phantoms, this study has provided a three-layer TMP (TLTMP) including skin, fat and muscle layers based on polyacrylamide gel (PAG).

Back to chromite as a mineralogical strategy for long-term chromium pollution control.

Re-oxidation of Cr(III) in treated Cr-contaminated sites poses a considerable source of Cr(VI) pollution, necessitating stable treatment solutions for long-term control. This study explores the immobilization of Cr(VI) into chromite, the most stable and weathering-resistant Cr-bearing mineral, under ambient conditions. Batch experiments demonstrate chromite formation at pH above 7 and Fe(III)/Cr(III) ratios exceeding 1, with Fe(III) occupying all tetrahedral sites, essential for stability.

Responses to Hypoxia and Hyperoxia in Embryonic Tiger Keelbacks (Rhabdophis tigrinus lateralis; Colubridae).

Studies examining the oxygen dependency of embryonic survival, growth, and differentiation have been conducted for decades in a diverse array of animal taxa but including only one oviparous snake, the viperine water snake Natrix maura. Here, we describe a study incubating eggs of the tiger keelback Rhabdophis tigrinus lateralis (Colubridae) under four oxygen conditions, hypoxia (7% and 11% O), normoxia (21% O), and hyperoxia (31% O), for different lengths or at different stages of incubation. The length of hypoxic exposure is important in affecting embryonic development in R.

Oxidative stress in asthma pathogenesis: mechanistic insights and implications for airway smooth muscle dysfunction.

Airway smooth muscle (ASM) dysfunction is a key factor in the narrowing of airways in asthma patients, characterized by excessive secretion of inflammatory factors, increased mass, and amplified contractile responses. These pathological features are instrumental in the propagation of airway inflammation, structural remodeling, and the escalation of airway hyperresponsiveness (AHR), which are also principal factors underlying the limitations of current therapeutic strategies. In asthmatic ASM, an imbalance between oxidant production and antioxidant defenses culminates in oxidative stress, which is involved in the excessive secretion of inflammatory factors, increased mass, and amplified contractile responses of ASM, and is a critical etiological factor implicated in the dysregulation of ASM function.

An opioid efficacy switch for reversible optical control of peripheral analgesia.

The mu-opioid receptor (MOR) is a major target for the treatment of pain. However, opioids are prone to side effects which limit their effectiveness as analgesics and can lead to opioid use disorders or, even, lethal overdose. The systemic administration of opioid agonists makes it both very difficult to decipher their underlying circuit mechanisms of action and to limit drug action to specific receptor subpopulations to isolate therapeutic effects from adverse side effects.

Neurodevelopmental toxicity and mechanism of action of monoethylhexyl phthalate (MEHP) in the developing zebrafish (Danio rerio).

Monoethylhexyl phthalate (MEHP) is the primary metabolite of di(2-ethylhexyl) phthalate (DEHP), the most prevalent phthalate plasticiser globally. It has been demonstrated that MEHP exerts more potent toxic effects than DEHP. Nevertheless, the full extent of the toxicity of MEHP to neurodevelopmental organisms remains unclear.

Effects of smoking cessation on individuals with COPD: a systematic review and meta-analysis.

Objective: Despite smoking being a significant risk factor in the occurrence and progression of chronic obstructive pulmonary disease (COPD), no comprehensive analysis has been conducted to determine the potential benefits of smoking cessation for patients with established COPD or identify specific indicators that may be improved. The aim of our meta-analysis was to elucidate the positive impact of smoking cessation on COPD.

Methods: We conducted a comprehensive search of PubMed, EMBASE, Web of Science, Cochrane Library, CNKI, Wan Fang and VIP databases to identify studies that met our eligibility criteria from inception up to 1, May 2024.

HIPSTR: highest independent posterior subtree reconstruction in TreeAnnotator X.

In Bayesian phylogenetic and phylodynamic studies it is common to summarise the posterior distribution of trees with a time-calibrated consensus phylogeny. While the maximum clade credibility (MCC) tree is often used for this purpose, we here show that a novel consensus tree method - the highest independent posterior subtree reconstruction, or HIPSTR - contains consistently higher supported clades over MCC. We also provide faster computational routines for estimating both consensus trees in an updated version of TreeAnnotator X, an open-source software program that summarizes the information from a sample of trees and returns many helpful statistics such as individual clade credibilities contained in the consensus tree.

We report a female patient with a right inguinal mass and ileocecal myxo carcinoma who was misdiagnosed as having a right incarcerated inguinal hernia invading the peritoneum incarcerated inguinal hernia and ileocecal myxo carcinoma.

Dose optimization of extended collimators in boron neutron capture therapy.

In this paper, we propose the design of extending collimators aimed at reducing the radiation dose received by patients with normal tissues and protecting organs at risk in Boron Neutron Capture Therapy (BNCT). Three types of extended collimators are studied: Type 1, which is a traditional design; Type 2, which is built upon Type 1 by incorporating additional polyethylene material containing lithium fluoride (PE(LiF)); Type 3, which adds lead (Pb) to Type 1. We evaluated the dose distribution characteristics of the above-extended collimators using Monte Carlo methods simulations under different configurations: in air, in a homogeneous phantom, and a humanoid phantom model.

Trophic niche variation driven by water level fluctuations facilitates the co-occurrence of invasive tilapia species in a subtropical reservoir in China.

Investigating how multiple invasive fish species with similar ecological traits respond to different environmental conditions is crucial to understanding their successful invasion and coexistence. Here, we used stomach content analysis and stable isotope analysis to analyse the effects of water level fluctuation on the trophic niche plasticity of three dominant co-occurring invasive tilapia species (Coptodon zillii, Sarotherodon galilaeus, and Oreochromis niloticus) in the Shanmei Reservoir, southern China. We found that the tilapia species exhibited an iliophagous habit with dietary variations between the high-water (HW) and low-water (LW) level periods.

Gradient Distributed and Tightly Integrated Perovskite Heterojunction Constructed by Electric Field-Driven Ion Deposition for High-Performance X-ray Detection.

Perovskite heterojunctions combine the advantages of two different components but suffer difficulties in the tightness of interconnection and limitation of material selection. Here we report an electric field-driven ion deposition (EFID) strategy that controllably deposits perovskite ions on heterogeneous single crystals to form a gradient heterojunction with tight integration. The interconnection force of the gradient heterojunction by the EFID method is much better than that of the solution-grown heterojunction, which is easily decomposed.
