How many human proteoforms are there?

Despite decades of accumulated knowledge about proteins and their post-translational modifications (PTMs), numerous questions remain regarding their molecular composition and biological function. One of the most fundamental queries is the extent to which the combinations of DNA-, RNA- and PTM-level variations explode the complexity of the human proteome. Here, we outline what we know from current databases and measurement strategies including mass spectrometry-based proteomics.

Characterization of Chlamydomonas reinhardtii Core Histones by Top-Down Mass Spectrometry Reveals Unique Algae-Specific Variants and Post-Translational Modifications.

The unicellular microalga Chlamydomonas reinhardtii has played an instrumental role in the development of many new fields (bioproducts, biofuels, etc.) as well as the advancement of basic science (photosynthetic apparati, flagellar function, etc.).

Language Brokering among Latino Immigrant Families: Moderating Variables and Youth Outcomes.

The children of immigrants often serve as language brokers, or cultural and linguistic intermediaries, between their families and the host culture. Although language brokering is common practice among immigrant communities, it is a growing body of research in need of theoretical grounding and further study. The present study empirically tested a theoretical model of the effects of language brokering with moderating variables, informed by the segmented assimilation literature, among 362 (48% female) Latino adolescents ranging in age from 11 to 18 years (M = 13.

Causal Evidence from Humans for the Role of Mediodorsal Nucleus of the Thalamus in Working Memory.

The mediodorsal nucleus of the thalamus (MD), with its extensive connections to the lateral pFC, has been implicated in human working memory and executive functions. However, this understanding is based solely on indirect evidence from human lesion and imaging studies and animal studies. Direct, causal evidence from humans is missing.

Vagus nerve stimulation improves working memory performance.

Vagus nerve stimulation (VNS) is used for treating refractory epilepsy and major depression. While the impact of this treatment on seizures has been established, its impact on human cognition remains equivocal. The goal of this study is to elucidate the immediate effects of vagus nerve stimulation on attention, cognition, and emotional reactivity in patients with epilepsy.

Final Conversations: Overview and Practical Implications for Patients, Families, and Healthcare Workers.

The current paper presents a summary of a 12-year body of research on final conversations, which will be useful for healthcare providers who work with patients and family nearing the end-of-life, as well as for patients and their family members. Final conversations encompass any and all conversations that occur between individuals with a terminal diagnosis and their family members (all participants are aware that their loved one is in the midst of the death journey). Final conversations take the family member's perspective and highlights what are their memorable messages with the terminally ill loved one.

We wanted to know whether misconceptions, or strongly held incorrect beliefs, differed by subject area or question type.

Methods: A total of 104 students completed two assessments that included 20 MCQs on endodontics and 20 MCQs on dental implants.

Deploying a quantum annealing processor to detect tree cover in aerial imagery of California.

Quantum annealing is an experimental and potentially breakthrough computational technology for handling hard optimization problems, including problems of computer vision. We present a case study in training a production-scale classifier of tree cover in remote sensing imagery, using early-generation quantum annealing hardware built by D-wave Systems, Inc. Beginning within a known boosting framework, we train decision stumps on texture features and vegetation indices extracted from four-band, one-meter-resolution aerial imagery from the state of California.

Wished for and avoided conversations with terminally ill individuals during final conversations.

The current investigation examines retrospectively wished for and avoided conversations during the end of life with a deceased relational partner. Participants reported on conversations they wished they had engaged in and conversations that they intentionally avoided, as well as reasons why they did not engage in the conversations. Analyses revealed the following wished for and avoided conversations: negative relationship characteristics; death and dying; postdeath arrangements; and personal information.

Greater Attention to Task-Relevant Threat Due to Orbitofrontal Lesion.

Injury to the orbitofrontal cortex (OFC) is a frequent consequence of head injury and may lead to dysfunctional regulation of emotional and social behavior. Dysfunctional emotional behavior may partly be related to the role of the OFC in emotion-attention interaction, as reported previously. In order to better understand its role in emotion-attention and emotion-cognitive control interactions, we investigated attention allocation to task-relevant and task-irrelevant threat-related emotional stimuli during a task requiring cognitive control in patients with lesion to the OFC.

Interaction of resistance training, electroacupuncture and Huang Qi supplementation on skeletal muscle function and GLUT4 protein concentration in rats.

Objective: To determine the effects and potential synergy of resistance training (RT), Huang Qi (HQ) herbal supplementation, and electroacupuncture (EA) on skeletal muscle mass, contractile properties, and components of the insulin signalling pathway in healthy Sprague Dawley rats.

Methods: Female Sprague Dawley rats were randomly assigned to one of five groups (n=8 each): control (CON), RT only, RT with EA (RT-EA), RT with HQ (RT-HQ), and RT combined with both EA and HQ (RT-EA-HQ). RT was performed using ladder climbing every other day for 8 weeks.

Geographic variation in gorilla limb bones.

Gorilla systematics has received increased attention over recent decades from primatologists, conservationists, and paleontologists. Studies of geographic variation in DNA, skulls, and teeth have led to new taxonomic proposals, such as recognition of two gorilla species, Gorilla gorilla (western gorilla) and Gorilla beringei (eastern gorilla). Postcranial differences between mountain gorillas (G.

Human Brain Reacts to Transcranial Extraocular Light.

Transcranial extraocular light affects the brains of birds and modulates their seasonal changes in physiology and behavior. However, whether the human brain is sensitive to extraocular light is unknown. To test whether extraocular light has any effect on human brain functioning, we measured brain electrophysiology of 18 young healthy subjects using event-related potentials while they performed a visual attention task embedded with emotional distractors.

Navigating Leadership Complexity Through Critical, Creative, and Practical Thinking.

This chapter explores specific applications in the areas of graduate leadership education, action research, service immersion program, and advising conversations. Additionally, it presents a framework of pathways to social change and suggests how such a framework can be useful to students and leadership educators.

Reactive oxygen species are involved in BMP-induced dendritic growth in cultured rat sympathetic neurons.

Previous studies have shown that bone morphogenetic proteins (BMPs) promote dendritic growth in sympathetic neurons; however, the downstream signaling molecules that mediate the dendrite promoting activity of BMPs are not well characterized. Here we test the hypothesis that reactive oxygen species (ROS)-mediated signaling links BMP receptor activation to dendritic growth. In cultured rat sympathetic neurons, exposure to any of the three mechanistically distinct antioxidants, diphenylene iodinium (DPI), nordihydroguaiaretic acid (NGA) or desferroxamine (DFO), blocked de novo BMP-induced dendritic growth.

The Nevada Rural Ozone Initiative (NVROI): Insights to understanding air pollution in complex terrain.

The Nevada Rural Ozone Initiative (NVROI) was established to better understand O3 concentrations in the Western United States (US). The major working hypothesis for development of the sampling network was that the sources of O3 to Nevada are regional and global. Within the framework of this overarching hypothesis, we specifically address two conceptual meteorological hypotheses: (1) The high elevation, complex terrain, and deep convective mixing that characterize Nevada, make this state ideally located to intercept polluted parcels of air transported into the US from the free troposphere; and (2) site specific terrain features will influence O3 concentrations observed at surface sites.

Drosophila muller f elements maintain a distinct set of genomic properties over 40 million years of evolution.

The Muller F element (4.2 Mb, ~80 protein-coding genes) is an unusual autosome of Drosophila melanogaster; it is mostly heterochromatic with a low recombination rate. To investigate how these properties impact the evolution of repeats and genes, we manually improved the sequence and annotated the genes on the D.

A central support system can facilitate implementation and sustainability of a Classroom-based Undergraduate Research Experience (CURE) in Genomics.

In their 2012 report, the President's Council of Advisors on Science and Technology advocated "replacing standard science laboratory courses with discovery-based research courses"-a challenging proposition that presents practical and pedagogical difficulties. In this paper, we describe our collective experiences working with the Genomics Education Partnership, a nationwide faculty consortium that aims to provide undergraduates with a research experience in genomics through a scheduled course (a classroom-based undergraduate research experience, or CURE). We examine the common barriers encountered in implementing a CURE, program elements of most value to faculty, ways in which a shared core support system can help, and the incentives for and rewards of establishing a CURE on our diverse campuses.

Electrophysiological response to omitted stimulus in sentence processing.

The current study provides evidence that the absence of a syntactically expected item leads to a sustained cognitive processing demand. Event-related potentials were measured at the omission of a syntactically expected object argument in a speech sequence. English monolingual adults listened to paired sentences.

Low attentional engagement makes attention network activity susceptible to emotional interference.

The aim of this study was to investigate whether emotion-attention interaction depends on attentional engagement. To investigate emotional modulation of attention network activation, we used a functional MRI paradigm consisting of a visuospatial attention task with either frequent (high-engagement) or infrequent (low-engagement) targets and intermittent emotional or neutral distractors. The attention task recruited a bilateral frontoparietal network with no emotional interference on network activation when the attentional engagement was high.
