Doxorubicin (DOX) is an anthracycline anti-tumor drug. However, its clinical use is limited by dose-dependent cardiotoxicity, and even progresses to chronic heart failure (CHF). OBJECTIVE: This study aims to investigate whether the Nrf2 activator, sulforaphane (SFN), can prevent DOX-induced CHF. METHODS: Male Sprague Dawley rats who received treatment for six weeks were divided into four groups (n=30 per group): control, SFN, DOX, and DOX plus SFN group. RESULTS: Results revealed that DOX induced progressive cardiac damage as indicated by increased cardiac injury markers, cardiac inflammation, fibrosis and oxidative stress...

An experiment was conducted to evaluate the effects of in ovo injection of chrysin, quercetin and ascorbic acid on hatchability, somatic attributes, hepatic antioxidant status and early post-hatch growth performance of broiler chicks. Four hundred and eighty embryonated broiler breeder eggs containing live 18-day-old embryos were divided into six groups of 80 eggs each. One group remained intact and served as a control group (i), whereas the other five groups were injected with the prepared injection solutions as follows: (ii) 0...

The estrogen-related receptor b (ESRRB) is an orphan nuclear receptor and targets many genes involved in self-renewal and pluripotency. In mouse ES cells, overexpression of ESRRB can maintain LIF-independent self-renewal in the absence of Nanog. However, the fundamental features of porcine ESRRB remain elusive. In this study, we revealed the expression profiles of ESRRB in both porcine pluripotent stem cells and early stage embryos and dissected the functional domains of ESRRB protein to prove that ESRRB is a key transcription factor that enhanced porcine pluripotent gene activation...

As waterlogging and successive events severely influence growth and development of economically important plants, we attempted to characterize the role of a waterlogging-responsive Group I (A-6) Ethylene response factor (MaRAP2-4) from Mentha arvensis. Waterlogging, ethylene and Methyl jasmonate rapidly induced the expression of MaRAP2-4. MaRAP2-4 interacted with multiple cis-elements like Dehydration response elements (DRE1/2), Anoxia/Jasmonic acid response element (JARE) and GCC box showing its involvement in multiple responses...

Selectivity control in hydroarylation-based C-H alkylation has been dominated by steric interactions. In contrast, we unravel a conceptually distinct strategy that exploits the programmed switch in the C-H activation mechanism by means of cobalt catalysis, setting the stage for expedient C-H alkylations with unactivated alkenes. Detailed mechanistic studies provided compelling evidence for a programmable switch in the C-H activation mechanism from a linear-selective ligand-to-ligand hydrogen transfer (LLHT) to a branched-selective base-assisted internal electrophilic-type substitution (BIES)...

Silibinin, which is derived from Silybum marianum (milk thistle), has used as a traditional remedy for liver or biliary disorders and known to have superior antioxidant activity. In addition, silibinin was recently reported to have antifungal effect related to fungal apoptosis against Candida albicans and the interest in the therapeutic effect is increasing. In this study, we found another mode of antifungal action of silibinin and its antibiofilm activity on C. albicans. To investigate influence on fungal plasma membrane, propidium iodide and bis-(1, 3-dibutylbarbituric acid) trimethineoxonol [DiBAC4 (3)] assay were primarily carried out...

As a de-ubiquitin enzyme, ubiquitin C-terminal hydrolase (UCH)-L1 has been shown to be overexpressed in several human cancers. However, the function of UCH-L1 in invasion of breast cancers is still unclear. Here we report that the expression of UCH-L1 is significantly higher in cancer cells with higher invasive ability. While ectopic UCH-L1 expression failed to alter cell proliferation in MCF-7 cells, it caused a significant upregulation of cellular invasion. Furthermore, siRNA mediated knockdown of UCH-L1 led to suppression of invasion in UCH-L1 overexpressing MCF-7 cells...

The development of a new decarboxylative cross-coupling protocol that affords terminal and substituted alkynes from various carboxylic acids is described using both nickel- and iron-based catalysts. The use of N-hydroxytetrachlorophthalimide (TCNHPI) esters is crucial to the success of the transformation, and the reaction is amenable to in situ carboxylic acid activation. Additionally, an inexpensive, commercially-available alkyne source is employed in this formal homologation process that serves as a surrogate for other well-established alkyne syntheses...

BACKGROUND: Many patient-reported outcome measures (PROMs) have been developed and/or used to measure the impact of amblyopia and strabismus on quality of life (QoL). Identifying the one with superior quality is important for evaluating the effectiveness of novel therapy for amblyopia and for directing improved clinical decision-making in adults considering strabismic surgery. Therefore, the aim of this review is to identify all PROMs previously developed/used to study the impact of amblyopia and/or strabismus on QoL and to appraise the quality and comprehensiveness of content of the disease-specific instruments...

OBJECTIVES: We designed a pilot study to evaluate safety and feasibility of an inexpensive and simple approach to intracoronary hemodilution during primary angioplasty (PPCI) to reduce reperfusion injury. INTRODUCTION: Early revascularization in acute myocardial infarction decreases infarct size and improves outcomes. However, abrupt restoration of coronary flow results in myocardial reperfusion injury and increased final infarct size. Dilution of coronary blood during revascularization may help reduce this damage...

Female Drosophila retain sperm for up to two weeks post-copulation in a network of storage organs includng the bursa, the seminal receptacle, and the spermathecae. This image shows the seminal receptacle of a Drosophila melanogaster female, 2-hrs post-copulation between a LHM (wild-type) female with a Protamine B (green), β-Tubulin (blue) fluorescently tagged male, whose sperm can be visualized within the female. This 'infinity' structure of the seminal receptacle resembles the tubular coil that allows for the storage of very long sperm relative to female body size -up to 20 times the length of the female in some Drosophila species...

Following brain injury astrocytes change into a reactive state, proliferate and grow into the site of lesion, a process called astrogliosis, initiated and regulated by changes in cytoplasmic Ca(2+) . Transient receptor potential canonical (TRPC) channels may contribute to Ca(2+) influx but their presence and possible function in astrocytes is not known. By RT-PCR and RNA sequencing we identified transcripts of Trpc1, Trpc2, Trpc3, and Trpc4 in FACS-sorted glutamate aspartate transporter (GLAST)-positive cultured mouse cortical astrocytes and subcloned full-length Trpc1 and Trpc3 cDNAs from these cells...

Percutaneous titanium implants for bone conduction devices (BCDs) have offered, since 1977, a solution for patients with hearing loss not treatable by conventional hearing aids, such as patients with chronic ear infections or microtia and/or ear canal atresia. Percutaneous implants imply a continuous breach in the mechanical defensive barrier of the skin. To compensate for this breach, immunological mechanisms in the subcutaneous tissue surrounding the implant become more active. This article is protected by copyright...

Extensive agricultural use of neonicotinoid insecticide products has resulted in the presence of neonicotinoid mixtures in surface waters worldwide. Although many aquatic insect species are known to be sensitive to neonicotinoids, the impact of neonicotinoid mixtures is poorly understood. In the present study, the cumulative toxicity of binary and ternary mixtures of select neonicotinoids (imidacloprid, clothianidin, and thiamethoxam) was characterized under acute (96-h) exposure scenarios using the larval midge Chironomus dilutus as a representative aquatic insect species...
