Indole-3-carboxaldehyde alleviates cisplatin-induced acute kidney injury in mice by improving mitochondrial dysfunction via PKA activation.

Cisplatin (DDP) is widely used in the treatment of cancer as a chemotherapeutic drug. However, its severe nephrotoxicity limits the extensive application of cisplatin, which is characterized by injury and apoptosis of renal tubular epithelial cells. This study aimed to reveal the protective effect and its underlying mechanism of Indole-3-carboxaldehyde (IC) against DDP-induced AKI in mice and NRK-52E cells pretreated with PKA antagonist (H-89).

Development of Sustainable Engineered Cementitious Composites by Incorporating Local Recycled Fine Aggregate.

In this study, sustainable engineered cementitious composites (ECC) exhibiting high tensile strength as well as high tensile strain capacity were successfully developed by incorporating polyethylene (PE) fiber, local recycled fine aggregate (RFA), and limestone calcined clay cement (LC). The improvement in tensile strength and tensile ductility was attributed to the self-cementing properties of RFA as well as the pozzolanic reaction between calcined clay and cement. Carbonate aluminates were also generated owing to the reaction between calcium carbonate in limestone and the aluminates in both calcined clay and cement.

Mechanical Performance and Constitutive Model Analysis of Concrete Using PE Fiber-Strengthened Recycled Coarse Aggregate.

To promote the sustainable development of the construction industry, concrete incorporating polyethylene (PE) fiber-strengthened recycled coarse aggregate (SRCA) and seawater and sea sand (SWSS) is prepared. The usage of SRCA significantly improves the mechanical performance of concrete. The strength is improved, and the failure mode of concrete cylinders is also remarkably altered.

Multiscale Investigation on the Performance of Engineered Cementitious Composites Incorporating PE Fiber and Limstone Calcined Clay Cement (LC).

Limestone calcined clay cement (LC) is successfully used to fabricate engineered cementitious composites (ECC) exhibiting tensile strength of 9.55 ± 0.59 MPa or tensile strain capacity of 8.

Cediranib Induces Apoptosis, G1 Phase Cell Cycle Arrest, and Autophagy in Non-Small-Cell Lung Cancer Cell A549 In Vitro.

Lung cancer remains the leading cause of cancer death worldwide. Late diagnosis, chemoresistance, and metastasis are the main reasons for the high mortality rate of lung cancer. Therefore, the development of other treatments is urgent.

Individual and successive detection of HS and HClO in living cells and zebrafish by a dual-channel fluorescent probe with longer emission wavelength.

Reactive oxygen species (ROS) and reactive sulfur species (RSS) participate in many physiological activities and help maintaining the redox homeostasis in biological system. The complicated intrinsic connection between specific ROS/RSS needs to be further explored. Herein, a novel fluorescent probe (MB-NAP-N) with longer emission wavelength has been rationally designed and synthesized based on the conjugation of the methylene blue moiety and the naphthalimide moiety for the detection of hypochlorous acid (HClO) and hydrogen sulfide (HS).

Role of miR-302/367 cluster in human physiology and pathophysiology.

MicroRNAs (miRNAs) are small non-coding RNAs that negatively regulate target mRNAs at the post-transcriptional level. Increasing evidence shows the involvement of miRNAs in diverse biological processes. miR-302/367 cluster is highly conserved among vertebrates and made up of five members, including miR-367, miR-302a, miR-302b, miR-302c and miR-302d.

Harnessing the targeting potential of differential radiobiological effects of photon versus particle radiation for cancer treatment.

Radiotherapy is one of the major modalities for malignancy treatment. High linear energy transfer (LET) charged-particle beams, like proton and carbon ions, exhibit favourable depth-dose distributions and radiobiological enhancement over conventional low-LET photon irradiation, thereby marking a new era in high precision medicine. Tumour cells have developed multicomponent signal transduction networks known as DNA damage responses (DDRs), which initiate cell-cycle checkpoints and induce double-strand break (DSB) repairs in the nucleus by nonhomologous end joining or homologous recombination pathways, to manage ionising radiation (IR)-induced DNA lesions.

The effects of the Wnt/β‑catenin signaling pathway on apoptosis in HeLa cells induced by carbon ion irradiation.

The molecular mechanisms underlying the biological effects of carbon ions are unclear. The aim of this study was to explore the Wnt/β‑catenin pathway in regulating carbon ion (12C6+) radiation‑induced cellular toxicity. HLY78 is a Wnt‑specific small molecular modulator, whose effects on 12C6+ radiation‑induced damage are mostly unknown.

A β-allyl carbamate fluorescent probe for vicinal dithiol proteins.

The first β-allyl carbamate fluorescent probe, AC-green, was reported for specifically imaging vicinal dithiol proteins (VDPs) in living systems. The probe displays low toxicity and features high sensitivity and fast response towards VDPs. A drastic loss of VDPs in a Parkinson's model was disclosed by AC-green, linking the fluctuation of VDP levels to Parkinson's disease for the first time.

Inhibition of Wnt signalling pathway by XAV939 enhances radiosensitivity in human cervical cancer HeLa cells.

Cervical cancer is the second most common malignant tumour threatening women's health. In recent years, heavy-ion beam therapy is becoming a newly emerging therapeutic mean of cancer; however, radio-resistance and radiation-induced damage constitute the main obstacles for curative treatment of cervical cancer. Therefore, to identify the radiosensitizers is essential.

Protective effects of phenformin on zebrafish embryonic neurodevelopmental toxicity induced by X-ray radiation.

Radiotherapy (RT) is a common treatment for head and neck cancers, but central nervous system function can be impaired by clinical radiation doses. This experimental study evaluated the protective efficacy of the anti-hyperglycaemic/anti-neoplastic agent phenformin against radiation-induced developmental toxicity in zebrafish embryos. Zebrafish embryos pre-treated with 25 μM phenformin 1 h before x-ray irradiation were compared to irradiation-only embryos for mortality, hatching rate, morphology, spontaneous movement, heart beat, larval swimming, activities of the antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT), malondialdehyde content (MDA, a by-product of membrane lipid oxidation), and acetylcholinesterase (AChE) activity.

Research progress on therapeutic targeting of quiescent cancer cells.

Cellular quiescence (G0) is a sleep-like cellular state that allows cells to maintain the ability to re-enter and exit the proliferative cycle. Quiescent cancer cells are considered a therapeutic challenge since they are often resistant to conventional chemoradiotherapy resulting in disease progression and relapse. To date, the majority of published studies have focused on identifying molecules that target proliferating tumor cells while limited information is available on methods to target quiescent cancer cells.

Herba Artemisiae Capillaris Extract Prevents the Development of Streptozotocin-Induced Diabetic Nephropathy of Rat.

Diabetic nephropathy (DN) is a major cause of end-stage renal disease throughout the world; until now there is no specific drug available. In this work, we use herba artemisiae capillaris extract (HACE) to alleviate renal fibrosis characterized by the excessive accumulation of extracellular matrix (ECM) in rats, aiming to investigate the protective effect of the HACE on DN. We found that the intragastric treatment of high-dose HACE could reverse the effect of streptozotocin not only to decrease the level of blood glucose and blood lipid in different degree but also further to improve renal functions.
