Dmitri Tsyboulski, Natalia Orlova, Peter Saggau
We present a frequency-multiplexed multi-site two-photon imaging method utilizing amplitude modulation of femtosecond laser pulses in the MHz range to tag each excitation beam and the corresponding fluorescence signals with specific frequencies. The frequency tags are generated with an interferometric scheme employing acousto-optic deflectors (AODs) to achieve precise spatial overlap of femtosecond laser pulses with periodically varying phase shift. Creating matching excitation beam patterns in each interferometer arm using multiple AOD driving frequencies, and subsequently overlapping these matching patterns, results in multiple encoded excitation beams with unique beat frequencies available for scanning...

Mental disorders (such as recurrent mood disorders, personality disorders, or psychotic disorders) come along with enduring impairment in daily life activities. Therefore psychotherapeutic actions in inpatient or outpatient settings require a life-span and participation-oriented treatment perspective. Participation-oriented treatment aims at social and vocational integration in general life despite enduringly recurring or resting symptoms. According to the model of health problems offered by the International Classification of Functioning, Disability and Health, ICF (WHO, 2001), disability can be defined as context-dependent activity impairment due to illness...

OBJECTIVES: Inadequate cardiac output is associated with a poor outcome following cardiac surgery and is generally modified by the use of positive inotropic agents, volume resuscitation, and pacing. Echocardiography-guided pacemaker optimization is used in the outpatient setting, using different variables including total isovolumic time and the Tei index. We sought to determine the acute impact of heart rate on cardiac electromechanics, cardiac output, and stroke volume in the perioperative setting...

Therapeutic hypothermia is recommended by international guidelines after cardio-circulatory arrest. However, the effects of different temperatures during the first 24 hours after deep hypothermic circulatory arrest (DHCA) for aortic arch surgery on survival and neurologic outcome are undefined. We hypothesize that temperature variation after aortic arch surgery is associated with survival and neurologic outcome. In the period 2010-2014, a total of 210 consecutive patients undergoing aortic arch surgery with DHCA were included...

BACKGROUND: Hypophosphatasia (HPP) is a rare genetic disorder resulting in variable alterations of bone formation and mineralization that are caused by mutations in the ALPL gene, encoding the tissue-nonspecific alkaline phosphatase (ALP) enzyme. METHODS: In this phase IIA open-label, single-center, intra-patient, dose-escalating study, adult patients with HPP received 3 ascending intravenous doses of 5, 10, and 20 mg/kg BPS804, a fully human anti-sclerostin monoclonal antibody, on days 1, 15, and 29, respectively...

The authors created a dance workshop for schizophrenic patients designed to address their singular experience of space, in which the categories of interior and exterior do not function as limits. The space of the workshop, which, paradoxically, is thought in terms of the psychic space of schizophrenic patients by playing on its borderless quality, creates a continuity between the psychiatric hospital and the external world, and thus helps to prevent the segregation and isolation of such patients. This continuity is established on the basis of both the physical architecture of the workshop setting and the practice of dancing itself...

Magnetooptical (MO) glasses and, in particular, Faraday rotators are becoming key components in lasers and optical information processing, light switching, coding, filtering, and sensing. The common design of such Faraday rotator materials follows a simple path: high Faraday rotation is achieved by maximizing the concentration of paramagnetic ion species in a given matrix material. However, this approach has reached its limits in terms of MO performance; hence, glass-based materials can presently not be used efficiently in thin film MO applications...

Heart failure is a common clinical syndrome caused by a variety of cardiac diseases. We report a rare case of familial transthyretin amyloidosis cardiomyopathy to heighten the awareness of this rare but lethal cause of heart failure, as therapeutic interventions such as liver or heart transplant could be curative in selected patients.

INTRODUCTION: QT has a long history of heart rate (HR) correction but limited investigations have been undertaken to assess the impact of cardiovascular parameters on left ventricular (LV) contractility in drug safety testing. Cardiac contractility is affected by preload (Cyon-Frank-Starling law), afterload (Anrep effect) and HR (Bowditch effect). We evaluated multi-parameter correction methods to help with dP/dtmax interpretation. METHODOLOGY: Modeling was undertaken using data from dogs in single or double 4×4 Latin square studies...

BACKGROUND: Patients with heart failure (HF) should exercise at 40%-60% heart rate reserve (HRR) during the first 3 weeks of an outpatient cardiac rehabilitation (CR) program and at 50%-80% HRR thereafter. Arbitrary methods to prescribe exercise intensity such as resting HR (RHR) plus 20 or 30 beats per minute (bpm) (RHR + 20 or RHR + 30) are recommended for inpatients after a myocardial infarction or those recovering from heart surgery. This approach has been repurposed by outpatient CR programs to prescribe exercise intensity for patients with HF, yet its efficacy has not been evaluated...

BACKGROUND/INTRODUCTION: Indoleamine 2,3-dioxygenase (IDO) metabolizes tryptophan to kynurenine. An increase of its activity is associated with severity in patients with pneumonia. In chronic obstructive pulmonary disease (COPD) patients, an elevation of serotonin has been reported. Experimental models showed that cigarette smoke inhibits monoamine oxidase (MAO) leading to higher levels of serotonin. We investigated the prognostic ability of tryptophan, serotonin, kynurenine, IDO, and tryptophan hydroxylase (TPH) to predict short- and long-term outcomes in patients with a COPD exacerbation...

Group B streptococcus and respiratory syncytial virus are leading causes of infant morbidity and mortality worldwide. No licensed vaccines are available for either disease, but vaccines for both are under development. Severe respiratory syncytial virus disease can be prevented by passively administered antibody. The presence of maternal IgG antibody specific to respiratory syncytial virus is associated with reduced prevalence and severity of respiratory syncytial virus disease in the first few weeks of life, whereas maternal serotype-specific anticapsular antibody is associated with protection against both early-onset and late-onset group B streptococcus disease...

BACKGROUND AND AIMS: Acute cholangitis (AC) is associated with high mortality of up to 10%. The association between timing of ERCP and mortality in AC patients remains unclear. The aim of this study was to investigate if early ERCP within 24 hours was associated with improved survival. METHODS: All AC patients that underwent ERCP at Odense University Hospital, Denmark, between March 2009 and September 2016 were identified using a prospective ERCP database. Clinical data were collected from medical records...

Since ventricular arrhythmias are a common cause of sudden cardiac death (SCD), treatment for ventricular arrhythmias is the target area of interest in research field. Among different means to prevent ventricular arrhythmias, catheter ablation (CA) has emerged as an effective therapeutic method. CA can decrease the likelihood of SCD in the following arrhythmia categories: 1) idiopathic ventricular fibrillation (VF) that is usually triggered by premature ventricular beats originating in the Purkinje fibres; 2) VF in subjects with structural heart disease, especially after myocardial infarction, that is triggered by premature ventricular beats from surviving Purkinje fibres; 3) Brugada syndrome in which modification of an epicardial substrate in the right ventricular outflow tract might be the most promising strategy; 4) recurrent monomorphic ventricular tachycardias in the setting of structural heart disease; 5) ventricular preexcitation in which CA appears to be a method of choice in high risk patients, regardless of the presence or absence of symptoms...

We simulate a semi-flexible active filament that exhibits spontaneous oscillations on clamping and show self-propulsion when left free. The activity on the filament relies on the nano-dimers distributed at regular intervals along the chain. With an emphasis on the spontaneous beating of a clamped filament, we demonstrate that the two competing forces necessary for oscillation are the elastic forces due to polymer rigidity and the active forces due to chemical activity. In addition, we also study the synchronization of two extensile filaments and the role played by non-local hydrodynamic interactions...
