Family and College Environmental Exposures Mediate the Relationship between Parental Education and Depression among College Students

Background Depression is a major health concern for college students due to its substantial morbidity and mortality. Although low parental education has been identified as a factor in depression in college students, the mechanisms through which parental educational achievement affects students’ depression are not well understood. We tested whether adverse family and college environments mediate the relationship between parental educational level and depression among Chinese college students. Methods A total of 5180 respondents were selected using a cross-sectional survey. We examined the association of parental education, adverse family and college environments with depression in college students using the Adolescent Self-Rating Life Events Checklist, Beck Depression Inventory and socio-demographic questionnaires. Results Lower parental educational level is significantly correlated with depression in college students in our sample. Additionally, low family economic status, paternal or maternal unemployment, long periods spent apart from family, family conflicts, having been scolded and beaten by parents, poor or dissatisfying test performance, conflict with friends, heavy course load and failure in selection processes are also associated with parental education. Low family economic status, paternal or maternal unemployment, long periods spent apart from family, family conflicts, poor or dissatisfying test performance, conflict with friends and heavy course load mediated the relationship between parental education and depression in college students. Conclusions Adverse family and college environments could explain the influence of parental educational level on depression in college students.
Propranolol for Recalcitrant Ulcerated Hemangioma of Infancy

Abstract: Hemangioma of infancy (HOI) is a common, self‐resolving, benign tumor that frequently requires no intervention. Ulceration is one of the main complications of HOI, and active treatment is usually required to manage pain, potential scarring, and occasionally bleeding and infection. Since the discovery that oral propranolol is an effective treatment for complicated HOI, it has been replacing systemic corticosteroids as first‐line therapy, and early recommendations for treatment protocols have been devised. We report the successful treatment of six children with recalcitrant ulcerated HOI using propranolol. In all cases, complete, rapid healing occurred. Two children experienced recurrence of ulceration after ceasing propranolol, but this was rapidly controlled by restarting treatment. No adverse effects were encountered. We propose that ulceration in HOI is an indication for propranolol treatment if more conservative therapies have failed.
Experiencing Simulated Aging Improves Knowledge of and Attitudes Toward Aging

Nursing assistants provide 90% of the functional and psychosocial care of older adults in nursing homes. Without knowledge of the normal physical changes of aging, it would be difficult to provide them with appropriate quality care. This quasi‐experimental study aimed to test the effects of the Elderly Simulation Program on nursing assistants' knowledge about aging, attitudes toward older adults, and the motivation to care for older adults in nursing homes. The program has two parts: a 1‐hour lecture about aging changes and a 1‐hour simulation of the roles of an older adult, a caregiver, and a “rusher” (20 minutes for each role). A convenience sample of 83 full‐time nursing assistants was recruited from nursing homes in Taiwan. The participants were assigned to an experimental (n = 43) or a control group (n = 40). The experimental group received the Elderly Simulation Program intervention, whereas the control group did not participate in any educational programs. Data were collected before the intervention and 4 wk after the program was completed. Results indicated that 4 wk after the intervention, the experimental group participants' knowledge about aging and attitudes toward older adults had significantly improved (all P < .001). The experimental group participants also had greater knowledge of aging than the control group at posttest (P < .001). It is recommended that the program be incorporated into the regular on‐the‐job continuing education of nursing assistants in long‐term care facilities to enhance their knowledge about aging and their attitudes towards older adults.
Lock-in Time-of-Flight (ToF) Cameras: A Survey

This paper reviews the state-of-the art in the field of lock-in time-of-flight (ToF) cameras, their advantages, their limitations, the existing calibration methods, and the way they are being used, sometimes in combination with other sensors. Even though lock-in ToF cameras provide neither higher resolution nor larger ambiguity-free range compared to other range map estimation systems, advantages such as registered depth and intensity data at a high frame rate, compact design, low weight, and reduced power consumption have motivated their increasing usage in several research areas, such as computer graphics, machine vision, and robotics.
Demonstration of Multi-Band Frequency-Selective Surfaces Using Split-Ring Triangular Resonators

Design, experimental and modeling studies have been undertaken on periodic, multi-frequency two-dimensional arrays of four differently sized metallic split-ring triangular resonators fabricated on a dielectric substrate. A sample consisting of quadrants of four differently dimensioned resonators showed only a broadened, apparently multimodal feature in the transmission spectrum. Four discrete resonances were achieved using a number of permutations of a primitive unit cell containing each of the triangular resonators. For each of the unit-cell permutations, four discrete resonances are predicted based on numerical simulation; however, the spectral intensities are shown to be markedly different in a subset of cases.
A low-cost, high-yield fabrication method for producing optimized biomimetic dry adhesives

We present a low-cost, large-scale method of fabricating biomimetic dry adhesives. This process is useful because it uses all photosensitive polymers with minimum fabrication costs or complexity to produce molds for silicone-based dry adhesives. A thick-film lift-off process is used to define molds using AZ 9260 photoresist, with a slow acting, deep UV sensitive material, PMGI, used as both an adhesion promoter for the AZ 9260 photoresist and as an undercutting material to produce mushroom-shaped fibers. The benefits to this process are ease of fabrication, wide range of potential layer thicknesses, no special surface treatment requirements to demold silicone adhesives and easy stripping of the full mold if process failure does occur. Sylgard® 184 silicone is used to cast full sheets of biomimetic dry adhesives off 4” diameter wafers, and different fiber geometries are tested for normal adhesion properties. Additionally, failure modes of the adhesive during fabrication are noted and strategies for avoiding these failures are discussed. We use this fabrication method to produce different fiber geometries with varying cap diameters and test them for normal adhesion strengths. The results indicate that the cap diameters relative to post diameters for mushroom-shaped fibers dominate the adhesion properties.
In vitro development of canine somatic cell nuclear transfer embryos in different culture media

The objective of the present study was to investigate the effects of three different culture media on the development of canine somatic cell nuclear transfer (SCNT) embryos. Canine cloned embryos were cultured in modified synthetic oviductal fluid (mSOF), porcine zygote medium-3 (PZM-3), or G1/G2 sequential media. Our results showed that the G1/G2 media yielded significantly higher morula and blastocyst development in canine SCNT embryos (26.1% and 7.8%, respectively) compared to PZM-3 (8.5% and 0%) or mSOF (2.3% and 0%) media. In conclusion, this study suggests that blastocysts can be produced more efficiently using G1/G2 media to culture canine SCNT embryos.
The Role of Oxidative Stress and Inflammation in Cardiovascular Aging

Age is an independent risk factor of cardiovascular disease, even in the absence of other traditional factors. Emerging evidence in experimental animal and human models has emphasized a central role for two main mechanisms of age-related cardiovascular disease: oxidative stress and inflammation. Excess reactive oxygen species (ROS) and superoxide generated by oxidative stress and low-grade inflammation accompanying aging recapitulate age-related cardiovascular dysfunction, that is, left ventricular hypertrophy, fibrosis, and diastolic dysfunction in the heart as well as endothelial dysfunction, reduced vascular elasticity, and increased vascular stiffness. We describe the signaling involved in these two main mechanisms that include the factors NF-κB, JunD, p66Shc, and Nrf2. Potential therapeutic strategies to improve the cardiovascular function with aging are discussed, with a focus on calorie restriction, SIRT1, and resveratrol.
Beyond Log Files: Using Multi-Modal Data Streams Towards Data-Driven KC Model Improvement

The increasing use of educational technologies in classrooms is producing vast amounts of process data that capture rich information about learning as it unfolds. The field of educational data mining has made great progress in using log data to build models that improve instruction and advance the science of learning. Thus far, however, the predictive and explanatory power of such models has often been limited to the actions that educational technologies can log. A major challenge in incorporating more contextually rich data streams into models of learning is collecting and integrating data from different sources and at different grain sizes. We present our methodological advances in automating the integration of log data with additional multi-modal (e.g., audio, screen video, webcam video) data streams. We also demonstrate several examples of how integrating multiple streams of data into the knowledge component (KC) model refinement process improves the predictive fit of student models and yields important pedagogical implications. This work represents an important advancement in facilitating the integration of rich qualitative details of students’ learning contexts into the quantitative approaches characteristic of EDM research.
Cloning, Expression and Purification of an Acetoacetyl CoA Thiolase from Sunflower Cotyledon

Thiolase I and II coexist as part of the glyoxysomal β-oxidation system in sunflower (Helianthus annuus L.) cotyledons, the only system shown to have both forms. The importance of thiolases can be underscored not only by their ubiquity, but also by their involvement in a wide variety of processes in plants, animals and bacteria. Here we describe the cloning, expression and purification of acetoacetyl CoA thiolase (AACT) in enzymatically active form. Use of the extensive amount of sequence information from the databases facilitated the efficient generation of the gene-specific primers used in the RACE protocols. The recombinant AACT (1233 bp) shares 75% similarity with other plant AACTs. Comparison of specific activity of this recombinant AACT to a previously reported enzyme purified from primary sunflower cotyledon tissue was very similar (263 nkat/mg protein vs 220 nkat/mg protein, respectively). Combining the most pure fractions from the affinity column, the enzyme was purified 88-fold with a 55% yield of the enzymatically active, 47 kDa AACT.
Current pathophysiological concepts in cerebral small vessel disease

The association between cerebral small vessel disease (SVD) – in the form of white matter lesions, infarctions, and hemorrhages – with vascular cognitive impairment (VCI), has mostly been deduced from observational studies. Pathological conditions affecting the small vessels of the brain and leading to SVD have suggested plausible molecular mechanisms involved in vascular damage and their impact on brain function. However, much still needs to be clarified in understanding the pathophysiology of VCI, the role of neurodegenerative processes such as Alzheimer’s disease, and the impact of aging itself. In addition, both genetic predispositions and environmental exposures may potentiate the development of SVD and interact with normal aging to impact cognitive function and require further study. Advances in technology, in the analysis of genetic and epigenetic data, neuroimaging such as magnetic resonance imaging, and new biomarkers will help to clarify the complex factors leading to SVD and the expression of VCI.
A practical projection-based postprocessing of block-coded images with fast convergence rate

At present, block-transform coding is probably the most popular approach for image compression. However, for the sake of its implementation, an image is partitioned into spatially adjoining blocks which are processed independently without considering inter-block correlation. So, this approach inescapably causes an annoying defect called a blocking artifact. In this letter, in order to reduce a blocking artifact appearing in block-coded images, a new quantization constraint set based on the theory of projection onto convex set (POCS) is proposed. This set can efficiently complement the drawbacks of the projection onto the other constraint sets, particularly the smoothness constraint set. Experimental results, using the proposed quantization constraint set as a substitute for the conventional quantization constraint set, show that the postprocessed images not only converge at a fast rate but also obtain better performance in both objective and subjective quality. Moreover, we know that the postprocessed images maintain the clearness of the decoded image before postprocessing.
Non-contact AFM with a nanoindentation technique for measuring the mechanical properties of thin films

The true residual area measured from atomic force microscopy (AFM) images can subsequently be used to recalculate the hardness of the material measured by nanoindentation more accurately. In this study, nanoindentation with non-contact AFM has been used to investigate the mechanical properties of thin CN films deposited by RF magnetron sputtering on silicon (100) substrates. Micro Raman spectroscopy was used to measure the structural properties of the CN film. The hardness was determined at different loads and depths from nanoindentation using conventional analysis by the well known Oliver and Pharr method. The indents were imaged using AFM, and true residual contact areas as well as hardness values were determined. The hardness values obtained by AFM agreed with the hardness measured by the Oliver and Pharr method.
Learning and Efficiency in Games with Dynamic Population

We study the quality of outcomes in repeated games when the population of players is dynamically changing, and where participants use learning algorithms to adapt to the dynamic environment. Price of anarchy has originally been introduced to study the Nash equilibria of one-shot games. Many games studied in computer science, such as packet routing or ad-auctions, are played repeatedly. Given the computational hardness of Nash equilibria, an attractive alternative in repeated game settings is that players use no-regret learning algorithms. The price of total anarchy considers the quality of such learning outcomes, assuming a steady environment and player population, which is rarely the case in online settings. In this paper we analyze efficiency of repeated games in dynamically changing environments. An important trait of learning behavior is its versatility to changing environments, assuming that the learning method used is adaptive, i.e., doesn't rely too heavily on experience from the distant past. We show that, in large classes of games, if players choose their strategies in a way that guarantees low adaptive regret, high social welfare is ensured, even under very frequent changes. A main technical tool for our analysis is the existence of a solution to the welfare maximization problem that is both close to optimal and relatively stable over time. Such a solution serves as a benchmark in the efficiency analysis of learning outcomes. We show that such a stable and close to optimal solution exists for many problems, even in cases when the exact optimal solution can be very unstable. We further show that a sufficient condition on the existence of stable outcomes is the existence of a differentially private algorithm for the welfare maximization problem. Hence, we draw a strong connection between differential privacy and high efficiency of learning outcomes in frequently changing repeated games. We demonstrate our techniques by focusing on two classes of games as examples: independent item auctions and congestion games. In both applications we show that adaptive learning guarantees high social welfare even with surprisingly high churn in the player population.
Atmospheric Moisture Content Effects on Ionic Liquid Wettability of Alumina

The contact angles or wettability of 7 Ionic Liquids, on an alumina substrate, have been measured under two different storage conditions. The first using a small amount of moisture content, the second with no moisture content. The contact angle of Ionic Liquid droplets on an alumina substrate were measured using an Attension Theta instrument with automated software. The results show that a small amount of moisture improves the wettability of the Ionic Liquid – alumina system and therefore subsequent uses of these liquids with alumina should take this into consideration.
Interfacial recombination in In(Al)GaAsSb/GaSb thermophotovoltaic cells

The authors have studied efficient p-on-n homo- (InGaAsSb/GaSb) and heterojunction (InGaAsSb/AlGaAsSb/GaSb) thermophotovoltaic (TPV) cells with respect to the recombination velocity at the cap-layer/emitter interface, S. In both cell types the open-circuit voltage, V{sub oc}, and the short-circuit current, J{sub ac}, have about the same sensitivity to S. The dark current, J{sub 0}, is the most sensitive of all. An examination of the essential factors in the one-dimensional minority-carrier diffusion model shows that under short-circuit conditions, photogenerated electrons diffuse rapidly away from the interface to the junction, whereas under open-circuit conditions, they remain in the emitter for a much longer bulk-recombination time, and therefore, they are more likely to recombine at the interface. A factor of 2.2 increase in S from 5 to 11 {times} 10{sup 4} cm/s produces a 25-mV decrease in V{sub oc}, a 12-% decrease in J{sub ac} or quantum efficiency, and a factor of two increase in J{sub 0}. This work points out the critical importance of interfacial recombination even in efficient TPV cells.

Human Cytomegalovirus UL50 and UL53 Recruit Viral Protein Kinase UL97, Not Protein Kinase C, for Disruption of Nuclear Lamina and Nuclear Egress in Infected Cells

ABSTRACT Herpesvirus nucleocapsids traverse the nuclear envelope into the cytoplasm in a process called nuclear egress that includes disruption of the nuclear lamina. In several herpesviruses, a key player in nuclear egress is a complex of two proteins, whose homologs in human cytomegalovirus (HCMV) are UL50 and UL53. However, their roles in nuclear egress during HCMV infection have not been shown. Based largely on transfection studies, UL50 and UL53 have been proposed to facilitate disruption of the nuclear lamina by recruiting cellular protein kinase C (PKC), as occurs with certain other herpesviruses, and/or the viral protein kinase UL97 to phosphorylate lamins. To investigate these issues during HCMV infection, we generated viral mutants null for UL50 or UL53. Correlative light electron microscopic analysis of null mutant-infected cells showed the presence of intranuclear nucleocapsids and the absence of cytoplasmic nucleocapsids. Confocal immunofluorescence microscopy revealed that UL50 and UL53 are required for disruption of the nuclear lamina. A subpopulation of UL97 colocalized with the nuclear rim, and this was dependent on UL50 and, to a lesser extent, UL53. However, PKC was not recruited to the nuclear rim, and its localization was not affected by the absence of UL50 or UL53. Immunoprecipitation from cells infected with HCMV expressing tagged UL53 detected UL97 but not PKC. In summary, HCMV UL50 and UL53 are required for nuclear egress and disruption of nuclear lamina during HCMV infection, and they recruit UL97, not PKC, for these processes. Thus, despite the strong conservation of herpesvirus nuclear egress complexes, a key function can differ among them.
[Prevalence and severity of domestic violence among pregnant women, Mexico].

OBJECTIVES To determine whether pregnancy is a risk factor for domestic violence and to compare prevalence and severity of violence reported by women before and during pregnancy. METHODS There were interviewed 468 women in the third trimester of pregnancy who were seen during prenatal visits at public clinics in the state of Morelos, Mexico. Emotional, physical and sexual violence were investigated. A severity index was built up. Logistic regression analysis was applied in order to identify the main variables associated to domestic violence during pregnancy. RESULTS The prevalence of domestic violence did not change significantly before and during pregnancy (32%). The prevalence of each type of violence remained the same. About 27% of women who reported violence during pregnancy did not have experience it before, and a comparable proportion had experienced violence before but not during pregnancy. The severity of emotional violence significantly increased during pregnancy (compared to the previous year) whereas the severity of physical violence decreased. Variables most clearly related to violence during pregnancy were: couple's past history of child abuse; women witnessing domestic violence during childhood; and violence in the year before pregnancy. Several risk scenarios were identified, which could be helpful for health care providers. CONCLUSIONS The results showed that emotional violence is more prevalent than physical and sexual violence, allowing for a better understanding of this phenomenon.
