Sapje zebrafish lack the protein dystrophin and are the smallest vertebrate model of Duchenne muscular dystrophy (DMD). Their small size makes them ideal for large-scale drug discovery screens. However, the extent that sapje mimic the muscle dysfunction of higher vertebrate models of DMD is unclear. We used an optical birefringence assay to differentiate affected dystrophic sapje larvae from their unaffected siblings and then studied trunk muscle contractility at 4-7 days post fertilization. Preparation cross-sectional area (CSA) was similar for affected and unaffected larvae, yet tetanic forces of affected preparations were only 30-60% of normal...

Surface nanobubbles are stable gaseous phases in liquids that form on solid substrates. While their existence has been confirmed, there are many open questions related to their formation and dissolution processes along with their structures and properties, which are difficult to investigate experimentally. To address these issues, we carried out molecular dynamics simulations based on atomistic force fields for systems comprised of water, air (N2 and O2), and a Highly Oriented Pyrolytic Graphite (HOPG) substrate...

Nina Coltart's freedom in addressing delicate areas such as spirituality and Buddhism within a psychoanalytic framework has opened borders between different psychoanalytic communities. This paper sets out to identify a deep-rooted philosophical tension that runs through several aspects of Coltart's work starting from her 'Slouching towards Bethlehem … or, thinking the unthinkable in psychoanalysis'. In exploring this central topic in depth psychology, of the distinction between thinkable and unthinkable contents, the author argues that it is not a fundamental distinction in Coltart's work but is rather a particular example of a more fundamental structural dichotomy which pervades her approach and which manifests in several different guises...

Host-guest inclusion complexes of β-cyclodextrin with two vitamins viz., nicotinic acid and ascorbic acid in aqueous medium have been explored by reliable spectroscopic, physicochemical and calorimetric methods as stabilizer, carrier and regulatory releaser of the guest molecules. Job's plots have been drawn by UV-visible spectroscopy to confirm the 1:1 stoichiometry of the host-guest assembly. Stereo-chemical nature of the inclusion complexes has been explained by 2D NMR spectroscopy. Surface tension and conductivity studies further support the inclusion process...

High-fidelity transmission of the genome through cell division requires that all sister kinetochores bind to dynamic microtubules (MTs) from opposite spindle poles. The application of opposing forces to this bioriented configuration produces tension that stabilizes kinetochore-microtubule (kt-MT) attachments. Defining the magnitude of force that is applied to kinetochores is central to understanding the mechano-molecular underpinnings of chromosome segregation; however, existing kinetochore force measurements span orders of magnitude...

Microporous membranes fabricated from hydrophobic polymers such as polyvinylidene fluoride (PVDF) have been widely used for membrane distillation (MD). However, hydrophobic MD membranes are prone to wetting by low surface tension substances, thereby limiting their use in treating challenging industrial wastewaters, such as shale gas produced water. In this study, we present a facile and scalable approach for the fabrication of omniphobic polyvinylidene fluoride (PVDF) membranes that repel both water and oil...

Diabetic macular edema (DME) can cause blindness in diabetic patients suffering from diabetic retinopathy (DR). DM parameters controls (glycemia, arterial tension, and lipids) are the gold standard for preventing DR and DME. Although the vascular endothelial growth factor (VEGF) is known to play a role in the development of DME, the pathological processes leading to the onset of this disease are highly complex and the exact sequence in which they occur is still not completely understood. Angiogenesis and inflammation have been shown to be involved in the pathogenesis of this disease...

The Fifty Shades trilogy by E.L. James has taken the world by storm and become a cultural phenomenon. The lack of contraceptive use in the erotic fiction, first pointed out by bloggers, is analysed in this article and compared to medical information. James may be praised for sexualising condom use. However, her protagonist makes poor choices in terms of hormonal contraception and is negligent about its use, resulting in an unintended pregnancy and resolved in marital bliss and motherhood. What is of more interest here than a possible message about contraceptive use, is the outcome that the fiction's negligence in birth control and responsibility affirms an ideology in which female sexuality and sexual experimentation can only be tolerated within the context of procreation and affirmation of motherhood...

Two small clinical trials indicated that administration of bovine intestinal alkaline phosphatase (AP) improves renal function in critically ill patients with sepsis-associated acute kidney injury (AKI), for which the mechanism of action is not completely understood. Here, we investigated the effects of a newly developed human recombinant AP (recAP) on renal oxygenation and hemodynamics and prevention of kidney damage and inflammation in two in vivo AKI models. To induce AKI, male Wistar rats (n=18) were subjected to renal ischemia (30min) and reperfusion (I/R), or sham-operated...

A 54-year-old male developed symptomatic scleral buckle exposure 16 years after placement and presented with large conjunctival defects with fibrosed edges. Following surgical removal of the buckle elements, primary conjunctival closure could not be achieved due to significant wound tension despite undermining the conjunctival edges to mobilize the conjunctiva. A dehydrated amniotic membrane graft (Ambio5; IOP Ophthalmics, Costa Mesa, CA) was placed on the scleral bed and secured in place with fibrin sealant (TISSEEL; Baxter International, Westlake Village, CA)...

There is little data comparing the surgical outcomes of tension-free vaginal tape (TVT) and transobturator tape (TOT) procedures in obese women. Therefore, we aimed to compare the surgical outcomes of TOT and TVT procedures among obese women with a diagnosis of stress urinary incontinence (SUI). One hundred and eighty-nine women who underwent TVT or TOT procedures due to pure SUI were included. Women in whom the body mass index (BMI) was ≥30 kg/m(2) were considered as obese, while <30 kg/m(2) were non-obese...

Adult clients with schizophrenia are primarily cared for by their ageing parents. When the parents become ill or die, siblings are considered to be responsible for taking over the caregiving role. However, little is known about caregiving for a sibling with schizophrenia, and no studies have explored this phenomenon in an Asian context. The aim of the present descriptive, qualitative study was to understand the experiences of being the primary caregiver of a sibling with schizophrenia. Data were collected from 10 siblings of currently-hospitalized patients diagnosed with schizophrenia using semistructured, in-depth interviews...

Emulsifiers for pesticide microemulsions contain a part of volatile organic compounds (VOCs), and ionic liquids (ILs) are becoming potential substitutes. In order to apply ILs in pesticide microemulsions, the study of interaction between ILs and surfactants is necessary. Therefore, the surface properties and aggregation of anionic surfactant sodium dodecyl sulfate (SDS) in ILs, including N-hexyl-N-methylmorpholinyl bromide ([C6mm][Br]), N-hexyl-N-methylpiperidyl bromide ([C6mp][Br]), N-hexyl-N-methylpyrrolidyl bromide ([C6mpyr][Br]), N-octyl-N-methylpyrrolidyl bromide ([C8mpyr][Br]), N-dodecyl-N-methylpyrrolidyl bromide ([C12mpyr][Br]) and N-hexadecyl-N-methylpyrrolidyl bromide ([C16mpyr][Br]), were investigated in terms of surface tension, conductivity, dynamic light scattering (DLS), viscosity, fluorescence, pseudo-ternary phase diagram and (1)H NMR measurements...

Many studies have demonstrated that depressed myofilament Ca(2+) sensitivity is common to dilated cardiomyopathy (DCM) in humans. However, it remains unclear whether a single determinant-such as myofilament Ca(2+) sensitivity-is sufficient to characterize all cases of DCM because the severity of disease varies widely with a given mutation. Because dynamic features dominate in the heart muscle, alterations in dynamic contractile parameters may offer better insight on the molecular mechanisms that underlie disparate effects of DCM mutations on cardiac phenotypes...

INTRODUCTION: Postoperative flattening of the upper lip with loss of lip pout and down turning of the corners of the mouth is often seen after Le Fort I surgery. We aim to determine which facial muscles are involved in this phenomenon to update the literature on this subject. METHODS: In 6 cadavers, a unilateral Le Fort I incision was executed. After removal of the skin, all individual facial muscles were identified and submitted to bilateral tactile traction, comparing incised sides with non-incised sides...

PURPOSE: To describe how athletes with disabilities talk about their experiences of participating in competitive disability sport in South Africa. METHOD: In-depth semi-structured interviews were conducted with 20 athletes with disabilities. Data were analysed via thematic content analysis using an inductive data driven process. RESULTS: Participants described their involvement in competitive sport as a positive experience; they described it as a catalyst for the recasting of identities and reframing an understanding of physical impairment, a context for empowerment and resistance of disablist attitudes, and an arena in which a sense of inclusion and belonging is experienced...
