Remediation of 2,4-dichlorophenol-contaminated soil by electrokinetic delivery of persulfate technology.

2,4-Dichlorophenol (2,4-DCP) is difficult to degrade rapidly in the environment due to its stable chemical properties, so it was easy to lead to serious chlorophenol pollution in soil. Consequently, a remediation method which is efficient, safe, and economical is required. In this study, electrokinetic (EK) remediation was used to transfer sodium persulfate (NaSO) into soil to degrade 2,4-DCP, and the effect of several factors (including the addition location of NaSO, applied voltage, and running time) on the remediation efficiency was explored.

The MT1 receptor as the target of ramelteon neuroprotection in ischemic stroke.

Stroke is the leading cause of death and disability worldwide. Novel and effective therapies for ischemic stroke are urgently needed. Here, we report that melatonin receptor 1A (MT1) agonist ramelteon is a neuroprotective drug candidate as demonstrated by comprehensive experimental models of ischemic stroke, including a middle cerebral artery occlusion (MCAO) mouse model of cerebral ischemia in vivo, organotypic hippocampal slice cultures ex vivo, and cultured neurons in vitro; the neuroprotective effects of ramelteon are diminished in MT1-knockout (KO) mice and MT1-KO cultured neurons.

The efficacy and safety of beinaglutide alone or in combination with insulin glargine in Chinese patients with type 2 diabetes mellitus who are inadequately controlled with oral antihyperglycemic therapy: A multicenter, open-label, randomized trial.

Design, synthesis, and biological evaluation of pyrido[2,3-d]pyrimidine and thieno[2,3-d]pyrimidine derivatives as novel EGFR inhibitors.

EGFR mutations have been identified in 20,000 reported NSCLC (non-small cell lung cancer) samples, and exon 19 deletions and L858R mutations at position 21, known as "classical" mutations, account for 85-90% of the total EGFR (epidermal growth factor receptor) mutations. In this paper, two series of EGFR kinase inhibitors were designed and synthesised. Among them, compound showed an IC value of 13 nM for kinase inhibitory activity against EGFR and more than 76-fold selectivity for EGFR.

This study was carried out to examine this relationship in patients with type 2 diabetes mellitus (T2DM).

Association of peripheral neuropathy with subclinical left ventricular dysfunction in patients with type 2 diabetes.

Objectives: The impacts of diabetic peripheral neuropathy (DPN) on clinical manifestations of left ventricular (LV) function in patients suffering from type 2 diabetes mellitus (T2DM) and the preserved LV ejection fraction (LVEF) lack a full evaluation. This study was carried out to investigate the correlation of peripheral neuropathy with subclinical LV systolic dysfunction, accompanied by the exploration of the relevant clinical features of peripheral neuropathy in these patients.

Methods: A retrospective analysis was conducted depending on the data of 101 consecutive inpatients with T2DM and preserved LVEF (all ≥ 50 %), without coronary artery disease and other histories of heart disease.

Knockdown of CLC-3 may improve cognitive impairment caused by diabetic encephalopathy.

Background: Diabetic encephalopathy(DE) is a neurological complication of diabetes, and its pathogenesis is unclear. Current studies indicate that insulin receptors and downstream signaling pathways play a key role in the occurrence and development of DE. Additionally, CLC-3, a member of the CLC family of anion channels and transporters, is closely related to the secretion and processing of insulin.

Pd-Catalyzed Rearrangement Reaction of -Tosylhydrazones Bearing Allyl Ethers Into -Olefin-Substituted Sulfonylhydrazones.

A novel and efficient rearrangement of -tosylhydrazones bearing allyl ethers into -olefin-substituted sulfonylhydrazones is proposed. The reaction involves breakage of the C-O bond and formation of the C-N bond. The reaction can be extended to a wide range of substrates, and the target products can be synthesized smoothly, regardless of the presence of electron-donating and electron-withdrawing groups.

Design, synthesis and biological evaluation of aminopyrimidine derivatives bearing a 4,5,6,7-tetrahydrothieno [3,2-c]pyridine as potent EGFR inhibitors.

To resolve the problem of drug resistance caused by epidermal growth factor receptor (EGFR) mutations in non-small cell lung cancer, we used the principle of collocation to design and synthesize a series of aminopyrimidine derivatives with 4,5,6,7-tetrahydrothieno [3,2-c]pyridine side chains (according to the binding mode of AZD9291 to EGFR) for use as EGFR kinase inhibitors. The most promising compound A12, a non-covalently bound reversible inhibitor, showed excellent kinase inhibitory activity against EGFR, with an IC value of 4.0 nM and more than 42-fold selectivity for EGFR (IC = 170.

The Fecal Microbiota Is Already Altered in Normoglycemic Individuals Who Go on to Have Type 2 Diabetes.

Objective: Mounting evidence has suggested a link between gut microbiome characteristics and type 2 diabetes (T2D). To determine whether these alterations occur before the impairment of glucose regulation, we characterize gut microbiota in normoglycemic individuals who go on to develop T2D.

Methods: We designed a nested case-control study, and enrolled individuals with a similar living environment.

Integrated Skin Transcriptomics and Serum Multiplex Assays Reveal Novel Mechanisms of Wound Healing in Diabetic Foot Ulcers.

Nonhealing diabetic foot ulcers (DFUs) are characterized by low-grade chronic inflammation, both locally and systemically. We prospectively followed a group of patients who either healed or developed nonhealing chronic DFUs. Serum and forearm skin analysis, both at the protein expression and the transcriptomic level, indicated that increased expression of factors such as interferon-γ (IFN-γ), vascular endothelial growth factor, and soluble vascular cell adhesion molecule-1 were associated with DFU healing.

TGF-beta/TGF-beta RII/CLC-3 axis promotes cognitive disorders in diabetes.

Transforming growth factor beta (TGF-beta) and Chloride channel-3 (CLC-3) are critical for inflammatory response, cellular proliferation and apoptosis in hippocampus neurons. However, the relationship between CLC-3 and TGF-beta/TGF-beta Receptor II (RII) pathway in diabetic encephalopathy (DE) is unknown. In this study, both diabetes rat model and diabetes cell model were employed to elucidate the mechanisms involved.

Amelioration of prediabetes-induced changes of dendritic structural plasticity.

Accumulating evidence suggests that the diabetes-induced cognitive dysfunction can be alleviated when exposed to the enriched environment. However, the impact of the changes of the hippocampal plasticity on the cognitive decline and the possible effect of an enriched environment in prediabetes are still not clearly documented. To explore the effect of enriched environment for prediabetes-induced changes of dendritic structural plasticity in hippocampus pyramidal and cognitive deficits, the praxiology experiments for evaluating of anxiety, spatial learning and memory of prediabetic Wistar were performed, and then the dendritic spine density was assessed in the hippocampal CA1 pyramidal neuronal region.

The multiple protective roles and molecular mechanisms of melatonin and its precursor N-acetylserotonin in targeting brain injury and liver damage and in maintaining bone health.

Melatonin is a neurohormone associated with sleep and wakefulness and is mainly produced by the pineal gland. Numerous physiological functions of melatonin have been demonstrated including anti-inflammation, suppressing neoplastic growth, circadian and endocrine rhythm regulation, and its potent antioxidant activity as well as its role in regeneration of various tissues including the nervous system, liver, bone, kidney, bladder, skin, and muscle, among others. In this review, we summarize the recent advances related to the multiple protective roles of melatonin receptor agonists, melatonin and N-acetylserotonin (NAS), in brain injury, liver damage, and bone health.
