Bacillus thuringiensis promotes the growth of numerous economically important crops. The present study presents the complete genome sequence for a mega plasmid present in the type strain of B. thuringiensis ATCC 10792, a typical spore-forming Gram-positive bacterium with insecticidal activity, and investigates its genetic characteristics. The genome was sequenced and assembled de novo using Pac-Bio sequencers and the Hierarchical Genome Assembly Process, respectively. Further genome annotation was performed, and a total of 489 proteins and a novel mega-plasmid (poh1) with 584,623 bps were identified...

Exposure to violence can harm women's overall health and well-being. Data suggest that one in three women in the United States experience some form of violence by an intimate partner in their lifetime. In this commentary, we describe the implications of intimate partner violence (IPV) on women's health, specifically for women of reproductive age. We use a life-course perspective to describe the compounded impact of IPV on preconception health. Preconception health generally refers to the overall health and well-being of women (and men) before pregnancy...

The first tenet of the Code of Ethics for Pharmacists of the American Pharmacists Association describes the relationship between the pharmacist and the patient as a covenant. The central argument of this commentary is that the symbolic language of covenant, the metaphor used to describe the pharmacist-patient relationship, should be formally acknowledged as an ideal theory or concept. However, before committing to this ideal, there should be resonance with the realities of pharmacy practice. This commentary argues that the intimate nature of a covenantal relationship is not a good fit with most contexts in which pharmacists practice...

The cell wall of Staphylococcus aureus is composed of peptidoglycan and the anionic polymers lipoteichoic acid (LTA) and wall teichoic acid. LTA is required for growth and normal cell morphology in S. aureus Strains lacking LTA are usually only viable when grown under osmotically stabilizing conditions or after the acquisition of compensatory mutations. LTA negative suppressor strains with inactivating mutations in gdpP , resulting in an increase in intracellular c-di-AMP levels, have been described previously...

Toll-like receptors (TLRs) play an important role in inflammatory and immunological responses, which are intimately related to neovascularization. However, the precise mode of action of TLR3 in neovascularization still remains ambiguous. In this study, we sought to investigate the role of TLR3 in pathological corneal neovascularization (CNV) using a mouse model of alkali-induced CNV. CNV was attenuated in TLR3-deficient mice, and the absence of TLR3 led to decreased production of stromal cell-derived factor 1 (SDF-1), a well-characterized cytokine that regulates the recruitment of endothelial progenitor cells (EPCs) to the sites of neo-angiogenic niches in the injured tissues...

Polyamines are small amino-acid derived polycations capable of binding negatively charged macromolecules. Bacterial polyamines are structurally and functionally diverse, and are mainly produced biosynthetically by PLP-dependent amino acid decarboxylases referred to as LAOdcs (Lysine-Arginine-Ornithine decarboxylases). In a phylogenetically limited group of bacteria, LAOdcs are also induced in response to acid stress. Here, we performed an exhaustive phylogenetic analysis of the AAT-fold LAOdcs which showcased the ancient nature of their short forms in Cyanobacteria and Firmicutes, and emergence of distinct subfamilies of long LAOdcs in Proteobacteria...

CONTEXT: Previous studies have established women's autonomy as an important determinant of several demographic outcomes in Sub-Saharan Africa, yet very few have considered intimate partner violence as one of these outcomes. METHODS: Data collected in 2017 from 2,289 women residing in 40 communities in Ghana were used to examine associations between three types of autonomy-economic decision making, family planning decision making and sexual autonomy-and women's experiences with physical, sexual, emotional and economic violence...

BACKGROUND: Carotid stenting stimulates intimal proliferation through platelet and stem cell activation. OBJECTIVE: The aim of this study is to evaluate whether the administration before or after carotid stenting of clopidogrel loading dose may play a role on circulating endothelial progenitor cells, stromal cell-derived factor-1α (SDF-1α) and neointimal hyperplasia. METHODS: We recruited 13 patients (aged 74.52±7.23) with indication of carotid revascularization and in therapy with salicylic acid and statin...

Violence against women is a disabler of dignity, liberty, and rights of the person, with murder being its extreme form for silencing the individual. Despite psycho-criminological research providing evidence that violence can happen across cultures, sexes, and societies, other findings show that some forms of violence i.e. Intimate Partner Violence (IPV), which involves more frequently women as victims, is not rare in contemporary society. The aim of this study is to analyze the violence against women, and how it escalates up to the point in which it aggravates into femicide...

With the publication of Wilfred Bion's text 'Learning from Experience,' psychoanalysis was afforded a new schema for understanding the processes and implications involved in an infant's contact with their caregivers. As a result, our conception of some of the most fundamental phenomena of psychic life was significantly enriched. By proposing his theory of alpha-functioning, Bion mapped out how meaningful connexions to the internal and external worlds become established in the mind. In contrast, and through working clinically with psychotic patients, Bion revealed how these ties can catastrophically come undone...

Aortic dissection (AD) involves tearing of the medial layer, creating a blood-filled channel called false lumen (FL). To treat dissections, clinicians are using endovascular therapy using stent grafts to seal the FL. This procedure has been successful in reducing mortality but has failed in completely re-attaching the torn intimal layer. The use of computational analysis can predict the radial forces needed to devise stents that can treat ADs. To quantify the hyperelastic material behavior for therapy development, we harvested FL wall, true lumen (TL) wall, and intimal flap from the middle and distal part of five dissected aortas...

Arctium lappa (burdock) is the most popular daily edible vegetable in China and Japan because of its general health tonic effects. Previous studies focused on the beneficial role of Arctigenin but neglected its potential side-effects and toxicities. In the present study, the sub-chronic toxicity profile of Arctigenin following 28 days of consecutive exposure was investigated in rats. The results showed that during the drug exposure period, Arctigenin -12 mg/kg administration resulted in focal necrosis and lymphocytes infiltration of heart ventricular septal muscle cells...

Nanoscale materials offer enormous opportunities for catalysis, sensing, energy storage, and so on, along with their superior surface activity and extremely large surface area. Unfortunately, their strong reactivity causes severe degradation and oxidation even under ambient conditions and thereby deteriorates long-term usability. Here superlative stable graphene-encapsulated nanoparticles with a narrow diameter distribution prepared via in situ chemical vapor deposition (CVD) are presented. The judiciously designed CVD protocol generates 3 nm size metal and ceramic nanoparticles intimately encapsulated by few-layer graphene shells...

Damaged corneas can lead to blindness. Due to the worldwide shortage of donor corneas there is a tremendous unmet demand for a robust corneal replacement that supports growth of the major corneal cell types. Commercial artificial corneas comprise plastic polymers that do not adequately support diverse cell growth. We present a new class of protein elastomer-dominated synthetic corneas with attractive performance that intimately couple biologically active tropoelastin to mechanically robust and durable protein silk...

Herein, we report a novel nanocomposite consisting of n-type Sn-doped hematite and p-type CaMn2 O4 nanowire (CaMn2 O4 /α-Fe2 O3 ). The nanocomposite was characterized by X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM), ultraviolet-visible absorption spectroscopy, X-ray photoelectron spectroscopy (XPS), which showed that nanospindle-like Sn-doped hematite and CaMn2 O4 nanowire contact intimately in the nanocomposite, resulting in efficient charge transfer and separation. Photoelectrochemical results reveal that the nanocomposite possesses higher donor density, enhanced conductivity and lower overpotential for dioxygen evolution...
