Roger F Loring
Mean-trajectory approximations permit the calculation of nonlinear vibrational spectra from semiclassically quantized trajectories on a single electronically adiabatic potential surface. By describing electronic degrees of freedom with classical phase-space variables and subjecting these to semiclassical quantization, mean-trajectory approximations may be extended to compute both nonlinear electronic spectra and vibrational-electronic spectra. A general mean-trajectory approximation for both electronic and nuclear degrees of freedom is presented, and the results for purely electronic and for vibrational-electronic four-wave mixing experiments are quantitatively assessed for harmonic surfaces with linear electronic-nuclear coupling...

Large-scale collections of induced pluripotent stem cells (iPSCs) could serve as powerful model systems for examining how genetic variation affects biology and disease. Here we describe the iPSCORE resource: a collection of systematically derived and characterized iPSC lines from 222 ethnically diverse individuals that allows for both familial and association-based genetic studies. iPSCORE lines are pluripotent with high genomic integrity (no or low numbers of somatic copy-number variants) as determined using high-throughput RNA-sequencing and genotyping arrays, respectively...

Translation of the expanded (ggggcc)n repeat in C9orf72 patients with amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) causes abundant poly-GA inclusions. To elucidate their role in pathogenesis, we generated transgenic mice expressing codon-modified (GA)149 conjugated with cyan fluorescent protein (CFP). Transgenic mice progressively developed poly-GA inclusions predominantly in motoneurons and interneurons of the spinal cord and brain stem and in deep cerebellar nuclei. Poly-GA co-aggregated with p62, Rad23b and the newly identified Mlf2, in both mouse and patient samples...

Introduction: Although effective treatments exist, most women who smoke during pregnancy neither seek nor receive treatment. Complementary and alternative medicine (CAM) treatments (eg, mindfulness, yoga, and acupuncture) may be attractive, low-cost options that can be used to assist a large proportion of pregnant women with smoking cessation. Methods: This study examined participant characteristics and treatment utilization among pregnant smokers in the National Survey on Drug Use and Health (NSDUH) and the National Health Interview Survey (NHIS) in order to explore the prevalence and predictors of CAM use for any purpose within this population...

A new technique for shaping microfluid flow, known as flow sculpting, offers an unprecedented level of passive fluid flow control, with potential breakthrough applications in advancing manufacturing, biology, and chemistry research at the microscale. However, efficiently solving the inverse problem of designing a flow sculpting device for a desired fluid flow shape remains a challenge. Current approaches struggle with the many-to-one design space, requiring substantial user interaction and the necessity of building intuition, all of which are time and resource intensive...

In a perspective of personalized care for smoking cessation, a better clinical characterization of smokers with schizophrenia (SZ) is needed. The objective of this study was to determine the clinical characteristics of SZ smokers with severe nicotine (NIC) dependence. 240 stabilized community-dwelling SZ smokers (mean age = 31.9 years, 80.4% male gender) were consecutively included in the network of the FondaMental Expert Centers for Schizophrenia and assessed with validated scales. Severe NIC dependence was defined by a Fagerstrom questionnaire score ≥ 7...

Rhizogenic Agrobacterium biovar 1 is the causative agent of hairy root disease (HRD) in the hydroponic cultivation of tomato and cucumber causing significant losses in marketable yield. In order to prevent and control the disease chemical disinfectants such as hydrogen peroxide or hypochlorite are generally applied to sanitize the hydroponic system and/or hydroponic solution. However, effective control of HRD sometimes requires high disinfectant doses that may have phytotoxic effects. Moreover, several of these chemicals may be converted to unwanted by-products with human health hazards...

BACKGROUND: The Risk Model is a validated prognostic schema for patients with oral cavity squamous carcinoma. Here, we examine the relationship between Worst Pattern of Invasion-type 5 (WPOI-5) and occult cervical metastases, and also present an interim observational analysis of the impact of adjuvant radiotherapy on patients with low-stage oral cancer classified as either high risk or WPOI-5 alone. METHODS: There were 323 patients with T1 T2 cNo oral cavity squamous carcinoma treated by primary resection, 152 of whom also underwent elective neck dissection (END)...

Brain-derived neurotrophic factor (BDNF) is a central modulator of neuronal development and synaptic plasticity in the central nervous system (CNS). This renders the BDNF-modulated tropomyosin receptor kinase B (TrkB) a promising drug target to treat synaptic dysfunctions. Using GRowth factor-driven expansion and INhibition of NotCH during maturation, the so-called GRINCH neurons were derived from human induced pluripotent stem (hiPS) cells. These GRINCH neurons were employed as model cells for pharmacological profiling of two TrkB-agonistic antibodies, hereafter referred to as AB2 and AB20...

OBJECTIVE: The 6-min walking test (6 MWT) is commonly used to assess obese patients' aerobic fitness, but it has rarely been compared with a direct measurement of maximal aerobic capacities (VO2max or VO2peak) in obese adults. The aim of this study was to investigate the relationship between the distance covered during a 6 MWT with objectively measured VO2peak and to propose a new equation to predict VO2peak from this walking test in obese patients. METHODS: One hundred and thirty-seven obese patients (45...

INTRODUCTION: Persistent or chronic intestinal ischemic injury (i3) can lead to severe malnutrition and acute mesenteric ischemia. Although recommended, revascularization of splanchnic arteries is sometimes unrealizable. MATERIAL AND METHODS: We report a case series of iloprost use in consecutive stable patients with persistent i3 unsuitable for revascularization followed in a tertiary care center. The feasibility of revascularization was discussed and ruled out by a multidisciplinary team, and informed consent was obtained prior to consideration of a vasoactive therapy...

PURPOSE: The aim of this study was to explore the treatment, patient, and impairment-related risk factors associated with upper limb dysfunctions in breast cancer survivors. METHODS: A cross-sectional study was performed in 274 women treated for breast cancer. The following risk factors were analysed by bivariable and multivariable analysis: 1) treatment-related variables (type of surgery, levels of lymph node dissected, radiotherapy, chemotherapy, hormone therapy and trastuzumab); 2) patient's related variables (age and Body Mass Index); 3) and finally impairment-related variables such as pain (intensity, quality and pressure hypersensitivity, signs of central sensitisation, the degree of pain catastrophizing and vigilance and awareness to pain), active ROM and upper limb strength were investigated...

The search for metabolites with longer detection times remains an important task in for example toxicology and doping control. The impact of these long term metabolites is highlighted by the high number of positive cases after reanalysis of samples that were stored for several years, e.g. samples of previous Olympic Games. A substantial number of previously alleged negative samples have now been declared positive due to the detection of various long term steroid metabolites of which the existence was unknown during the Olympic Games of 2008 and 2012...

The European Society for Clinical Nutrition has published recommendations on the 'definition and classification of intestinal failure (IF)'. Two criteria must be present: a 'decreased absorption of macronutrients and/or water and electrolytes due to a loss of gut function' and the 'need for parenteral support'. Home parenteral support (HPS) is the primary treatment for chronic IF but is associated with complications. Areas covered: The principal cause of chronic IF is short bowel syndrome (SBS). The aim of treatment is to maximize intestinal absorption and reduce or eliminate the need for HPS to achieve the best possible quality of life...

While the treatment of colorectal cancer continues to rely heavily on conventional cytotoxic therapy, an increasing number of targeted agents are under development. Many of these treatments require companion diagnostic tests in order to define an appropriate population that will derive benefit. In addition, a growing number of biomarkers provide prognostic information about a patient's malignancy. As we learn more about these biomarkers and their assays, selecting the appropriate companion diagnostic becomes increasingly important...
