Functional chloroplast generation depends on the precise coordination of gene expression between the plastid and the nucleus and is essential for plant growth and development. In this study, a rice (Oryza sativa) mutant that exhibited albino and seedling-lethal phenotypes was isolated from a(60)Co-irradiated rice population. The mutant gene was identified as an ortholog of the Arabidopsis plastid transcriptionally active chromosome protein 2 (pTAC2) gene, and the mutant strain was designated osptac2. Sequence and transcription analyses showed that OspTAC2 encodes a putative chloroplast protein consisting of 10 pentratricopeptide repeat (PPR) domains and a C-terminal small MutS-related (SMR) domain...

The Morris water maze (MWM) spatial learning task has been demonstrated to involve a cognitive switch of action control to serve the transition from an early towards a late learning phase. However, the molecular mechanisms governing this switch are largely unknown. We employed MALDI MS imaging (MSI) to screen for changes in expression of small proteins in brain structures implicated in the different learning phases. We compared mice trained for 3days and 30days in the MWM, reflecting an early and a late learning phase in relation to the acquisition of a spatial learning task...

The use of commercially available autonomous underwater vehicles (AUVs) has increased during the last fifteen years. While they are mainly used for routine survey missions, there is a set of applications that nowadays can be only addressed by manned submersibles or work-class remotely operated vehicles (ROVs) equipped with teleoperated arms: the intervention applications. To allow these heavy vehicles controlled by human operators to perform intervention tasks, underwater structures like observatory facilities, subsea panels or oil-well Christmas trees have been adapted, making them more robust and easier to operate...

Skunk cabbage (Symplocarpus renifolius) blooms in early spring and its inflorescence, referred to as the spadix, can produce enough heat to melt snow. Here, we investigated glycolytic carbon flow at the PEP branch-point in thermogenic spadices. Our analyses revealed that petals and pistils in thermogenic florets exhibited higher expression of SrPEPC and SrAOX transcripts than those of SrPK, SrPEPCK, and SrPEPtase. Moreover, enzymatic analyses showed high activities of PEPC in the extracts from thermogenic florets...

BACKGROUND: Inadequate adherence to prescribed analgesics may be one of the reasons why patients with cancer experience unrelieved pain. Adherence is directly influenced by patients' barriers about pain management. Patient pain education programs (PEPs) have been developed to reduce patients' barriers and increase patients' adherence to their analgesics. The purpose of this article was to evaluate patients' adherence in patients receiving a pain consult and patient pain education in comparison with patients receiving standard pain treatment (standard care [SC]), to better explore the difficulties in medication adherence in cancer-related pain and the effects of PEP...

OBJECTIVES: N-Acetyl-D-neuraminic acid (Neu5Ac) is often synthesized from exogenous N-acetylglucosamine (GlcNAc) and excess pyruvate. We have previously constructed a recombinant Escherichia coli strain for Neu5Ac production using GlcNAc and intracellular phosphoenolpyruvate (PEP) as substrates (Zhu et al. Biotechnol Lett 38:1-9, 2016). RESULTS: PEP synthesis-related genes, pck and ppsA, were overexpressed within different modes to construct PEP-supply modules, and their effects on Neu5Ac production were investigated...

The ability to adjust attentional focus to varying levels of task demands depends on the adaptive recruitment of cognitive control processes. The present study investigated for the first time whether the mobilization of cognitive control during response-conflict trials in a flanker task is associated with effort-related sympathetic activity as measured by changes in the RZ-interval at a single-trial level, thus providing an alternative to the pre-ejection period (PEP) which can only be reliably measured in ensemble-averaged data...

UDP-N-acetylglucosamine enolpyruvyl transferase (MurA) is one of the key enzymes involved in peptidoglycan biosynthesis. The peptide HESFWYLPHQSY (called PEP 1354) is an inhibitor of MurA with an IC50 value of 200 μM. In this paper, we have used the FlexPepDock ab-initio protocol from the Rosetta program Homology Modeling and Molecular dynamics simulations to analyze, for the first time, the interaction of the PEP 1354 peptide with MurA enzyme from Pseudomonas aeruginosa (MurA-PA). Our modeling results suggest that the peptide binds to the same active site as the natural substrate UDP-N-acetylglucosamine (UNAG)...

INTRODUCTION: Premature ejaculation is a common sexual disorder, which is usually underreported. Multiple treatment methodologies are in use due to the absence of an effective, universally acceptable treatment modality. The most common drug used is dapoxetine, which has adverse effects limiting its long-term use. Hence, we decided to evaluate the effectiveness of 'on demand' silidosin 4 mg in patients with premature ejaculation, who were dissatisfied with dapoxetine 30 mg. MATERIAL AND METHODS: The study included 64 patients who reported premature ejaculation who were unhappy with the treatment with 'on demand' dapoxetine 30 mg, either due to its adverse effects or because of its overall inefficacy...

INTRODUCTION: Individuals with autism spectrum disorder (ASD) who also exhibit severe-to-moderate ranges of intellectual disability (ID) still face many challenges (i.e., less evidence-based trials, less inclusion in school with peers). METHODS: We implemented a novel model called the "Developmental and Sequenced One-to-One Educational Intervention" (DS1-EI) in 5- to 9-year-old children with co-occurring ASD and ID. The treatment protocol was adapted for school implementation by designing it using an educational agenda...

Cell penetrating peptides are useful tools for intracellular delivery of nucleic acids. Delivery of plasmid DNA, a large nucleic acid, poses a challenge for peptide mediated transport. The paper investigates and compares efficacy of five novel peptide designs for complexation of plasmid DNA and subsequent delivery into cells. The peptides were designed to contain reported DNA condensing agents and basic cell penetrating sequences, octa-arginine (R8 ) and CHK6 HC coupled to cell penetration accelerating peptides such as Bax inhibitory mutant peptide (KLPVM) and a peptide derived from the Kaposi fibroblast growth factor (kFGF) membrane translocating sequence...

People who repeatedly present for post-exposure prophylaxis (PEP) for prevention of HIV following a high-risk sexual exposure are of concern according to the British HIV Association PEP guidelines. The aim of this audit was to determine the extent of repeat PEP prescriptions for men who have sex with men (MSM) by conducting a retrospective review of patient notes from a 5-year period at one genitourinary medicine clinic. Over the 5 years, 107 of 929 MSM (11.5%; 95% confidence interval: 9.45-13.55) received more than one PEP prescription (repeat range 1-8; mean=3...

Matrix metalloproteinases (MMPs) are critical for the degradation of the extracellular matrix (ECM), which includes cartilage-specific collagen types I, II and XI. We previously found that PEP-1-sirtuin (SIRT)2 could induce dedifferentiation of articular chondrocytes; however, the underlying mechanisms remains unclear. We addressed this in the present study by examining the association between PEP-1-SIRT2 and the expression of MMP-1 and MMP-13 and type II collagen in rabbit articular chondrocytes. We found that PEP-1-SIRT2 increased MMP-1 and -13 expression in a dose- and time-dependent manner, as determined by western blotting...

The design and development of functional biomimetic systems for programmed stem cell response is a field of topical interest. To mimic bone extracellular matrix, we present an innovative strategy for constructing drug-loaded composite nanofibrous scaffolds in this study, which could integrate multiple cues from calcium phosphate mineral, bioactive molecule, and highly ordered fiber topography for the control of stem cell fate. Briefly, inspired by mussel adhesion mechanism, a polydopamine (pDA)-templated nanohydroxyapatite (tHA) was synthesized and then surface-functionalized with bone morphogenetic protein-7-derived peptides via catechol chemistry...
