Association and dissociation of particles are elementary steps in many natural and technological relevant processes. For many such processes, the presence of multiple binding sites is essential. For instance, protein complexes and regular structures such as virus shells are formed from elementary building blocks with multiple binding sites. Here we address a fundamental question concerning the role of multivalency of binding sites in the association kinetics of such complexes. Using single replica transition interface sampling simulations, we investigate the influence of the multivalency on the binding kinetics and the association mechanism of patchy particles that form polyhedral clusters...

This article presents a case of malignant transformation of vestibular schwannoma 13 years after stereotactic radiation therapy, which lead to an acute life-threatening condition. Although the observation is currently only based on case reports, an increasing number of these support the hypothesis that there is a relevant risk of malignant transformation in the long-term course of previously irradiated vestibular schwannomas. Therefore, long-term MRI follow-up should be considered.

The activity of the transcription factor nuclear factor-erythroid 2 p45-derived factor 2 (NRF2) is orchestrated and amplified through enhanced transcription of antioxidant and antiinflammatory target genes. The present study has characterized a triazole-containing inducer of NRF2 and elucidated the mechanism by which this molecule activates NRF2 signaling. In a highly selective manner, the compound covalently modifies a critical stress-sensor cysteine (C151) of the E3 ligase substrate adaptor protein Kelch-like ECH-associated protein 1 (KEAP1), the primary negative regulator of NRF2...

Background/Objective: A post-bladder tumor resection dose of MMC can reduce non-invasive papillary (pTa) bladder cancer recurrences by up to 40%; this treatment is recommended in both the AUA and EUA non-muscle-invasive bladder cancer guidelines. A common complication of this treatment is eosinophilic cystitis. Symptoms range from mild urinary frequency and urgency to debilitating pain and dysuria. Currently, there is no established treatment algorithm for MMC-induced cystitis. Methods: Members of the Urologic Surgery Quality Collaborative (USQC), a group composed of over 160 private and academic urologists, met to discuss the management of patients with cystitis following MMC therapy...

The development of neurons and vessels shares striking anatomical and molecular features, and it is presumably orchestrated by an overlapping repertoire of extracellular signals. CNS macrophages have been implicated in various developmental functions, including the morphogenesis of neurons and vessels. However, whether CNS macrophages can coordinately influence neurovascular development and the identity of the signals involved therein is unclear. Here, we demonstrate that activity of the cell surface receptor CD95 regulates neuronal and vascular morphogenesis in the post-natal brain and retina...

Recent genetic, molecular and post-mortem studies suggest impaired dopamine (DA)-D2 receptor (D2R) trafficking in patients with schizophrenia (SZ). Imaging and preclinical studies have shown agonist-induced D2R internalization can be imaged with positron emission tomography (PET) using D2R radiotracers combined with psychostimulant challenge. This is feasible if radiotracer binding is measured when postchallenge DA levels have returned to baseline, following the initial competition phase between DA and radiotracer for binding to D2R...

Intentionally defect-rich zinc oxide (ZnO) nanorod-arrays were grown from solution by carefully adjusting the concentration ratio of the growth-precursors used followed by various post-deposition thermal treatments. Post-deposition rapid thermal annealing (RTA) at moderate temperatures (350 °C-550 °C) and in various atmospheres was applied to vary the defect composition of the grown nanorod-arrays. It is demonstrated that, intense, defect-related orange emission occurs solely upon RTA around 450 °C and is essentially independent of the atmosphere used...

We report the first example of reversible encapsulation of micron-sized particles by oppositely charged submicron smaller colloids. The reversibility of this encapsulation process is regulated by pH-responsive poly(acrylic acid) (PAA) present in solution. The competitive adsorption between the small colloids and the poly(acrylic acid) on the surface of the large colloids plays a key role in the encapsulation behavior of the system. pH offers an experimental knob to tune the electrostatic interactions between the two oppositely charged particle species via regulation of the charge density of the poly(acrylic acid)...

BACKGROUND: Spirituality and religiosity may serve as both a resource and a barrier to HIV prevention with young black men who have sex with men (YBMSM). We examined indices of spirituality/religiosity as correlates of binge drinking, stimulant use, and recent HIV testing in a sample of YBMSM. METHODS: From 2011-2013, annual venue-based surveys of sexually active YBMSM ages 18-29 were conducted in Dallas and Houston, Texas. Binge drinking and stimulant use were assessed in the past two months...

There is limited understanding about the health and well-being of men who have sex with men (MSM) with HIV infection living in rural African areas. We present the results of an adapted photovoice project with 35 MSM with HIV infection who live in townships in Mpumalanga, South Africa. The project was designed to explore the social factors that influenced HIV care. Twenty-four photo essays were developed by participants in focus group discussions that were audio-recorded and transcribed for analysis. Transcripts and photo essays were coded using a constant comparison approach combining researcher observation notes and reflection on participant-identified themes...

In this paper, we demonstrate the stabilization of polystyrene microspheres by encapsulating them with dumbbell-shaped colloids with a sticky and a nonsticky lobe. Upon adding a depletant, an effective short ranged attraction is induced between the microspheres and the smaller, smooth lobes of the dumbbells, making those specifically sticky, whereas the interaction with the larger lobes of the dumbbells is considerably less attractive due to their rough surface, which reduces the overlap volume and leaves them nonsticky...

Young men who have sex with men (MSM) of color are at increased risk for HIV infection. Mpowerment (MP) is an intervention designed to reduce risky sexual behavior and increase HIV testing among young MSM ages 18-29. From 2009 to 2012, three community-based organizations with support from the U.S. Centers for Disease Control and Prevention evaluated MP among N = 298 participants. Following a repeated measures design, data from 3- and 6-month follow-ups were compared to baseline. HIV testing and self-efficacy for safer sex increased at both follow-up time points; self-acceptance as an MSM was higher at follow-up 2...

Harmful algal blooms (HABs) are a natural global phenomena emerging in severity and extent. Incidents have many economic, ecological and human health impacts. Monitoring and providing early warning of toxic HABs are critical for protecting public health. Current monitoring programmes include measuring the number of toxic phytoplankton cells in the water and biotoxin levels in shellfish tissue. As these efforts are demanding and labour intensive, methods which improve the efficiency are essential. This study compares the utilisation of a multitoxin surface plasmon resonance (multitoxin SPR) biosensor with enzyme-linked immunosorbent assay (ELISA) and analytical methods such as high performance liquid chromatography with fluorescence detection (HPLC-FLD) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) for toxic HAB monitoring efforts in Europe...

BACKGROUND: Contemporary speech processing strategies in cochlear implants (CIs) such as the Advanced Combination Encoder (ACE) use a standard Fast Fourier Transform (FFT) filterbank to extract envelopes. The assignment of the FFT bins to approximate the frequency resolution of the basilar membrane is only partly based on physiology, especially since the bins are distributed linearly below 1000Hz and logarithmically above 1000Hz. NEW METHOD: A Gammatone filterbank which provides a closer approximation to the bandwidths of filters in the human auditory system could replace the standard FFT filterbank in the ACE strategy...
