Avital Guedj, Anat Geiger-Maor, Eithan Galun, Hagai Amsalem, Jacob Rachmilewitz
Aging is associated with progressive decline in cell function and with increased damage to macromolecular components. DNA damage, in the form of double-strand breaks (DSBs), increases with age and in turn, contributes to the aging process and age-related diseases. DNA strand breaks triggers a set of highly orchestrated signaling events known as the DNA damage response (DDR), which coordinates DNA repair. However, whether the accumulation of DNA damage with age is a result of decreased repair capacity, remains to be determined...

Endotracheal intubation is a common daily procedure used for sustaining life in premature and term neonates in the neonatal intensive care unit. This procedure can be associated with some iatrogenic complications. One of these complications is ingesting a laryngoscope light bulb, and it is an extremely rare complication in neonates. The consequences of ingestion or aspiration may be serious and life-threatening. Herein, a male premature neonate, ingested a laryngoscope light bulb during endotracheal intubation because of surfactant replacement therapy, is reported...

#3
Ruolei Gu, Jing Yang, Yuanyuan Shi, Yi Luo, Yu L L Luo, Huajian Cai
We propose that self-affirmation may endow people more psychological resources to buffer against the negative influence of rejecting unfair offers in the classic ultimatum game (UG) and further lead to a stronger tendency to reject those offers. We tested this possibility by conducting an event-related potential (ERP) study about the UG, with the ERP component P3 as an indirect indicator of psychological resources. Participants were randomly assigned to the affirmation or control condition and then completed the UG through electrophysiological recording...

Xiao Wang, Xiaoquan Zhao
Previous self-affirmation research has shown that individuals who are allowed to reflect on their values and self-worth are less likely to exhibit message derogation and are more likely to accept risk information and change their behaviors compared to those who are not. However, the underlying mechanisms for the effect are unclear. Based on a randomized experiment (N = 331), we examined the mediating role of temporal considerations in participants' health-related cognitions and emotional responses. We found that self-affirmed participants (vs...

Chemical doping is a widely-used strategy to improve the performance of TiO2 for the dye-sensitized solar cells (DSCs). However, the effect of two efficient dopants has been rarely investigated. We present the synthesis of GO@SnO2/TiO2 nanofibers (NFs) by a facile method using electrospinning and hydrothermal processes. The synthesized NFs are described in terms of morphology, crystallinity and chemistry through FESEM, TEM, HR-TEM, XRD, EDX, XPS, FT-IR and Raman spectra. As the results, the axial ratio and the average diameter of NFs decreased after the hydrothermal treatment and calcination process, respectively...

Thomas Küpper
This essay proposes drawing on Homi K. Bhabha's concept of colonial mimicry to theorize the young-old's imitation of midlife. Bhabha states: "colonial mimicry is the desire for a reformed, recognizable Other, as a subject of a difference that is almost the same, but not quite". On an abstract level, similarities can be found in what is expected of the young-old: the young-old are to orient themselves towards middle-age norms, yet only to a certain degree and only when respecting the allegedly natural differences between the ages of life...

Justin Solomon, Alexandre Ba, François Bochud, Ehsan Samei
PURPOSE: To use novel voxel-based 3D printed textured phantoms in order to compare low-contrast detectability between two reconstruction algorithms, FBP (filtered-backprojection) and SAFIRE (sinogram affirmed iterative reconstruction) and determine what impact background texture (i.e., anatomical noise) has on estimating the dose reduction potential of SAFIRE. METHODS: Liver volumes were segmented from 23 abdominal CT cases. The volumes were characterized in terms of texture features from gray-level co-occurrence and run-length matrices...

BACKGROUND: There is growing interest in value-based health care in the United States. Statistical analysis of large databases can inform us of the factors associated with and the probability of adverse events and unplanned readmissions that diminish quality and add expense. For example, increased operating time and high blood urea nitrogen (BUN) are associated with adverse events, whereas patients on antihypertensive medications were more likely to have an unplanned readmission. Many surgeons rely on their knowledge and intuition when assessing the risk of a procedure...

Sahil Chaudhary, Peggy Compton
BACKGROUND: Ongoing opioid analgesic use in patients suffering from chronic non-malignant pain (CNMP) has been associated with the development of opioid misuse, abuse, addiction, and overdose. To prevent these adverse outcomes, it is important that family nurse practitioners (FNPs) implement recommended risk mitigation practices (RMPs) when treating CNMP patients with opioids. METHODS: A national sample of 856 FNPs was invited to answer an online survey about their utilization of opioids and RMPs in treating CNMP...

REVIEW
Ya-Chen Tina Shih, Chun-Ru Chien
The American Society of Clinical Oncology released its first guidance statement on the cost of cancer care in August 2009, affirming that patient-physician cost communication is a critical component of high-quality care. This forward-thinking recommendation has grown increasingly important in oncology practice today as the high costs of cancer care impose tremendous financial burden to patients, their families, and the health care system. For the current review, a literature search was conducted using the PubMed and Web of Science databases to identify articles that covered 3 topics related to patient-physician cost communication: patient attitude, physician acceptance, and the associated outcomes; and 15 articles from 12 distinct studies were identified...

Considering a historically diversified (and growing) population in the United States, one's ethnic identification is often an important psychological-as well as social and political-construct because it can serve as a hindrance to interpersonal interaction. Despite the importance of ethnic identity in psychological research, the most widely developed ethnic identity measurement tool, the Multigroup Ethnic Identity Measure (MEIM; Phinney, 1992), lacks consensus regarding its psychometric properties. The purpose of this article is to identify the factor structure of this measure and identify whether it exhibits measurement equivalence/invariance (ME/I) across ethnicities...

Importance: Developmental stuttering is a neuropsychiatric condition of incompletely understood brain origin. Our recent functional magnetic resonance imaging study indicates a possible partial basis of stuttering in circuits enacting self-regulation of motor activity, attention, and emotion. Objective: To further characterize the neurophysiology of stuttering through in vivo assay of neurometabolites in suspect brain regions. Design, Setting, and Participants: Proton chemical shift imaging of the brain was performed in a case-control study of children and adults with and without stuttering...

Spinal muscular atrophy (SMA) is a common autosomal recessive disorder in humans and is the leading genetic cause of infantile death. Patients lack the SMN1 gene with the severity of the disease depending on the number of copies of the highly homologous SMN2 gene. Although motoneuron death in the Smn+/- transgenic mouse model of mildest form of SMA, SMA type III, has been reported, we have used retrograde tracing of sciatic and femoral motoneurons in the hindlimb with recording of muscle and motor unit isometric forces to count the number of motoneurons with intact neuromuscular connections...

BACKGROUND: In our pediatric practice, we have observed qualitatively limited improvement in the image quality of images generated with sinogram affirmed iterative reconstruction (SAFIRE) compared to series generated with filtered back projection (FBP), particularly in cases near or below a CT dose index volume (CTDIvol) of 1-mGy. OBJECTIVE: To determine whether the image quality advantage of SAFIRE remains constant across clinically used CT dose levels in an American College of Radiology (ACR) CT accreditation phantom including the lower dose range used in pediatric imaging...

A Nawaz, W G Mao, C Lu, Y G Shen
The nanoscale elastic-plastic response of single crystal 4H-SiC has been investigated by nanoindentationwith a Berkovich tip. The hardness (H) and elastic modulus (E) determined in the load-independent region were 36±2GPa and 413±8GPa, respectively. The indentation size effect (ISE) of hardness within an indentation depth of 60nm was systematically analyzed by the Nix-Gao model. Pop-in events occurring at a depth of ~23nm with indentation loads of 0.60-0.65mN were confirmed to indicate the elastic-plastic transition of the crystal, on the basis of the Hertzian contact theory and Johnson's cavity model...

An association between vitamin D deficiency and early dental implant failure is not properly verified, but its role in osteoimmunology is discussed. This article illustrates two case reports with vitamin D deficiency and early implant failure. Prior to implant placement, the first patient received crestal bone grafting with autologous material. Both patients received dental implants from different manufacturers in the molar region of the mandible. In the case of bone grafting in the first patient, all implants were placed in a two-stage procedure...
