The Meaning of Temporal Balance: Does Meaning in Life Mediate the Relationship Between a Balanced Time Perspective and Mental Health?

The construct of a Balanced Time Perspective (BTP) predicts a variety of indices of mental health and well-being. We argue that one possible intermediate link between BTP and well-being may be an individual's sense of presence of meaning in life. Participants ranging in age from 19 to 88 years (N = 192) completed two measures of time perspective (Zimbardo Time Perspective Inventory [ZTPI] and the modified Balanced Time Perspective Scale [mBTPS]), mental health, personality, and meaning in life.

2,6-Di-tert-butylphenol and its quinone metabolite trigger aberrant transcriptional responses in C57BL/6 mice liver.

2,6-Di-tert-butylphenol (2,6-DTBP) is used as an antioxidant with wide commercial applications and its residues have been detected in various environmental matrices. 2,6-DTBP may enter human body via ingestion, inhalation or other exposure pathways. However, its susceptibility to biotransformation and potential of the metabolic products to trigger aberrant transcriptional responses remain unclear.

The study includes 12 sets of about 100 genomes each collected between and . We analyzed the mutations, mutation frequency and count trends over time, and genomes trends over time from January through September.

Colon cancer survival in California from 2004 to 2011 by stage at diagnosis, sex, race/ethnicity, and socioeconomic status.

Background: Disparities in cancer survival exist between groups. This study aims to examine these disparities in stage-, sex-, race/ethnicity-, and socioeconomic-specific colon cancer net survival in California for adults diagnosed between 2004 and 2011.

Methods: We estimated age-standardized net survival using the Pohar Perme estimator for colon cancer by stage at diagnosis (localized, regional, and distant), sex, race/ethnicity (Non-Hispanic White, Non-Hispanic Black, and Hispanic), and socioeconomic status (SES).

Post-acute care use patterns among Hospital Service Areas by older adults in the United States: a cross-sectional study.

Background: Despite the success of stroke rehabilitation services, differences in service utilization exist. Some patients with stroke may travel across regions to receive necessary care prescribed by their physician. It is unknown how availability and combinations of post-acute care facilities in local healthcare markets influence use patterns.

Validity of the Somatic Complaints Scales of the MMPI-2-RF in an Outpatient Chronic Pain Clinic.

Chronic pain has become a significant medical issue. The Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) is a broadband psychological test that has been validated for use across various medical settings and can aid in the assessment and treatment planning of chronic pain. In the current investigation, it was hypothesized that the somatic complaints scales of the MMPI-2-RF would demonstrate good convergent validity from a structured psychodiagnostic interview and other measures of pain and somatization, and lack gender bias.

ELAC2, an Enzyme for tRNA Maturation, Plays a Role in the Cleavage of a Mature tRNA to Produce a tRNA-Derived RNA Fragment During Respiratory Syncytial Virus Infection.

Respiratory syncytial virus (RSV) is the most common cause of lower respiratory tract infection in young children. However, effective treatment against RSV is unavailable. tRNA-derived RNA fragments (tRFs) are a recently discovered family of non-coding RNAs.

A kinematics-based model for the settling of gravity-driven arbitrary-shaped particles on a surface.

A discrete model is proposed for settling of an arbitrary-shaped particle onto a flat surface under the gravitational field. In this method, the particle dynamics is calculated such that (a) the particle does not create an overlap with the wall and (b) reaches a realistic equilibrium state, which are not guaranteed in the conventional discrete element methods that add a repulsive force (torque) based on the amount of overlap between the particle and the wall. Instead, upon the detection of collision, the particle's kinematics is modified depending on the type of contact, i.

Musical reward across the lifespan.

Music is ubiquitous. Despite the fact that most people find music enjoyable, there are individual differences in the degree to which listeners derive pleasure from music. However, there has been little focus on how musical reward may change across the lifespan.

Combined toxic effects of dioxin-like PCB77 with Fe-based nanoparticles in earthworm Eisenia fetida.

Iron-based nanomaterials hold promise for in situ remediation of persistent halogenated contaminants such as dioxin-like polychlorinated biphenyls, however, their complex interactions and joint toxicity toward beneficial soil biological functions remain unknown. This study examined the effects of nano-zero valent iron (nZVI) on the physiological and morphological changes, on the bioaccumulation of co-existed dioxin-like 3,3',4,4'-tetrachloro-biphenyls (PCB77), and the joint toxicity of nZVI and PCB77 in earthworms Eisenia fetida. An orthogonally designed experiment was conducted through the exposure of E.

Nonideal behavior of void volume markers in polar-organic chiral HPLC on polysaccharide-based chiral stationary phases.

Polysaccharide-based chiral stationary phases account for a majority of chiral HPLC separations. Their behavior in normal-phase and reversed-phase modes of separation has been studied extensively. However, much less is known about their behavior in polar-organic mode.

Improved Detonation Performance Via Coordination Substitution: Synthesis and Characterization of Two New Green Energetic Coordination Polymers.

In this work, a new energetic coordination polymer (ECP), [Cu(HBTI)(HO)] () (HBTI = 4,5-bistetrazole-imidazole), was synthesized by a hydrothermal method. Due to the existence of coordination water molecules in , however, its energy density was limited, which led to the insufficient detonation performance. To further improve its detonation performance, [Cu(HBTI)(NO)] () was then obtained by substituting the coordinated water molecule in with nitrate through the coordination substitution reaction under acidic conditions.

The Importance of AGO 1 and 4 in Post-Transcriptional Gene Regulatory Function of tRF5-GluCTC, an Respiratory Syncytial Virus-Induced tRNA-Derived RNA Fragment.

Respiratory syncytial virus (RSV) is the most common cause of lower respiratory tract infection in infants, the elderly, and immune-compromised patients. It is also a significant contributor to upper respiratory tract infection in the pediatric population. However, its disease mechanisms are still largely unknown.

An Investigation of the Eating Concerns Scale of the Minnesota Multiphasic Personality Inventory-3 (MMPI-3) in a Postoperative Bariatric Surgery Sample.

Eating pathology is common pre-operatively and continues to be prevalent following bariatric surgery. A new version of the Minnesota Multiphasic Personality Inventory (MMPI), the MMPI-3, contains a new scale called Eating Concerns (EAT) that aims to assess problematic eating behaviors. The current investigation seeks to establish preliminary convergent validity of the MMPI-3 EAT scale in a postoperative bariatric surgery sample.

Nanocars with Permanent Dipoles: Preparing for the Second International Nanocar Race.

With the desire to synthesize surface-rolling molecular machines that can be translated and rotated with extreme precision and speed, we have synthesized a series of five nanocars. Each structure features a permanent dipole moment, generated by an ,-dimethylamino- moiety on one end of the car coupled with a nitro group on the other end. These cars are designed to be stimulated with an electric field gradient from a scanning probe microscopy tip.

Psychosocial Functioning of Bariatric Surgery Patients 6-Years Postoperative.

Introduction: Mental health professionals routinely assess psychosocial risk factors prior to bariatric surgery to help identify factors that may impede surgical outcomes. Data regarding longer-term psychosocial functioning postoperatively are needed.

Purpose: Assess the psychosocial functioning of patients who obtained bariatric surgery approximately 6 years ago.

Differences Between Attached and Detached Cadaveric Prosections on Students' Identification Ability During Practical Examinations.

Cadaveric prosections are effective learning tools in anatomy education. They range from a fully dissected, sometimes plastinated, complete cadaver (in situ prosections), to a single, carefully dissected structure detached from a cadaver (ex situ prosections). While most research has focused on the advantages and disadvantages of dissection versus prosection, limited information is available on the instructional efficacy of different prosection types.

Survival analysis for the inverse Gaussian distribution with the Gibbs sampler.

This paper describes a comprehensive survival analysis for the inverse Gaussian distribution employing Bayesian and Fiducial approaches. It focuses on making inferences on the inverse Gaussian (IG) parameters and and the average remaining time of censored units. A flexible Gibbs sampling approach applicable in the presence of censoring is discussed and illustrations with Type II, progressive Type II, and random rightly censored observations are included.

Beers with Peers: Childhood ADHD and Risk for Correlated Change in Perceived Peer and Personal Alcohol Use Across Young Adulthood.

Background: ADHD poses risk for problematic alcohol use through adulthood. Perceived peer alcohol use, one of the strongest correlates of individuals' own alcohol use, is especially salient for adolescents with ADHD. The extent to which this risk extends into young adulthood is unknown, as well as how change in these constructs is associated throughout young adulthood.

Understanding the Economic Behavior of the Medically Uninsured in the United States.

Previous research defining the health consequences of being medically uninsured show worse access, poorer health outcomes, and higher rates of premature death as compared to their insured counterparts. Adding to this literature, the present study investigated the associative role of health insurance with personal finance health behaviors. In a representative sample of the general population, our adjusted models indicated significant relationships (both positive and negative) between being uninsured and these personal finance behaviors.

Sleep Problems and Posttraumatic Stress: Children Exposed to a Natural Disaster.

Objective: Sleep plays a critical role in children's growth and development. This study examined the frequency and persistence of children's sleep problems following a natural disaster, risk factors for children's sleep problems, and the bidirectional relationship between children's sleep problems and posttraumatic stress symptoms (PTSS) over time.

Methods: This study assessed 269 children (53% female, M = 8.

High intensity training during spaceflight: results from the NASA Sprint Study.

Historically, International Space Station (ISS) exercise countermeasures have not fully protected astronauts' musculoskeletal and cardiorespiratory fitness. Although these losses have been reduced on more recent missions, decreasing the time required to perform in-flight exercise would permit reallocation of that time to other tasks. To evaluate the effectiveness of a new training prescription, ISS crewmembers performed either the high intensity/lower volume integrated Sprint resistance (3 d wk) and aerobic (interval and continuous workouts, each 3 d wk in alternating fashion) exercise program ( = 9: 8M/1F, 48 ± 7 y, 178 ± 5 cm, 77.
