A Case of Spindle Cell Carcinoma of the Oral Cavity: With Special Reference to Cytopathological Features and Review of Literature

A case of spindle cell carcinoma of the oral cavity: with special reference to cytopathological features and review of literature. Oral Med Pathol 2006; 11: 127-132, ISSN 1342-0984 Spindle cell carcinoma (SPCC) is a relatively rare tumor and its histogenesis is controversial, since the spindle cell feature is often difficult to differentiate from sarcomatous lesions. We report a case of SPCC arising from the base of the tongue and its cytological and immunohistochemical findings are highlighted. Cytologically, the smear revealed two kinds of tumor cells: squamous and spindle-like cells. The spindle shaped-cells showed sarcomatous features while the atypical squamous cell nuclei were hyperchromatic with increased N/C ratio. Histopathology showed SCC and proliferation of spindle shaped cells. Histochemistry revealed a moderately dense amount of collagen fibers in the stroma. Immunohistochemically, the SCC component was positive for keratin and EMA and the spindle cell component was positive for vimentin. These results were considered to support the concept of a malignant epithelial cell undergoing metaplastic alterations. The study also suggested that a proper cytological and histological recognition of this lesion is important.
Effects of Adverse Childhood Experiences, Stress, and Social Support on the Health of College Students

The goal of the study was to describe the nature of adverse childhood experiences (ACEs) reported by undergraduates and to examine the effect of ACEs, perceived stress, and perceived social support on their health. Although respondents (N = 321) had parents with relatively high levels of education and indicated generally high levels of social support, results nevertheless showed a relatively high level of mental health problems and rates of ACEs that were similar to those in the general population in the state. Those with higher levels of ACEs had greater levels of stress and lower levels of social support. ACEs, social support, and stress explained more than half the variance in mental health scores, with stress making the greatest contribution. Despite the fact that we used different measures and an independent sample, findings generally replicated a previous study. Results point to a need to increase awareness of the association between ACEs and health on college campuses, to examine the effects of ACEs in more detail, and to design ACE-informed programs for this population.
Factors and Characteristics of Workplace Violence Against Nurses: A Study in Iran

Violence against nurses is a serious problem that can affect negatively the quality of nursing care. The extent of violence against nurses in Iran and the factors leading to this violence have not been known. Thus, the aim of this study was to investigate all forms of violence against nurses in Shahrekord hospitals in 2014. In this 2014 study, 100 nurses working in Shahrekord’s Hajar, Kashani, and Social Security branch hospitals were studied. Data were collected through standardized questionnaires on workplace violence, as well as demographic data, in health units on five types of violence, including physical and verbal violence, intimidation and bullying, ethnic violence, and violation of chastity. The analysis was done by SPSS (Version 19) software. All nurses indicated that during some period of their work, they had been subjected to at least one type of violence; the highest prevalence of mental violence was belonged to the subtype of intimidation and bullying (91%). The primary agents of violence against nurses were patients and their relatives. Factors such as gender, age, work experience, and nursing shifts played important roles in the distribution of violence. In ethnic violence, the only factor affecting nurses was race (p < .05). The highest rate of violence against nurses was due to mental or psychological violence. To minimize violence in hospitals, authorities should consider appropriate preventive strategies, good management, proper protective measures, and public education.
Actinomycin D and Hydrocortisone: Intracellular Binding in Rat Liver

In the report "Actinomycin D and hydrocortisone: interacellular binding in rat liver" by C. W. Dingman and M. Sporn (149, 1251, 10 Sept. 1965), the heading of column 5, Table 3, should have read, "RNA/DNA ratiost. " The last footnote to the table should have read, "The first ratio in each pair was determined on a sample of nuclei used for measuring in vivo incorporation of cytidine-H-3; the second ratio in each pair was determined on a sample of nuclei used for measuring in vitro incorporation of CTP-H3. " In column 5, the ratios in each pair should have been separated by a semicolon. As printed, the table implies, incorrectly, that only one ratio, rather than two, is reported.
A human model to determine folate bioavailability from food: a pilot study for evaluation

Background: Knowledge about folate bioavailability from food is essential for the estimation of dietary requirements. Yet, there is a lack of data obtained from validated human studies performed with physiological folate doses. Objective: In this pilot study, a new model for the determination of folate absorption is developed and validated. Design: Under strictly standardized procedures, two healthy ileostomy volunteers consumed single portions of test foods or an oral dose of a pharmaceutical folate preparation of the natural folate diastereomer (6S)-5- methyltetrahydrofolate. Relative folate absorption from oral doses versus an intramuscular injection of the same pharmaceutical preparation was determined using postdose plasma folate concentration curves. Nonabsorbed folate was estimated by postdose folate excretion into stomal effluent. Results: Estimated by plasma areas under the curve, relative folate absorption ranged from 47 to 67% for oral doses from the te st foods strawberries and broccoli and the pharmaceutical (6S)-5-methyltetrahydrofolate preparation. During 10 h postdose, 19-44% of the dietary folate was excreted with the stomal effluent. Varying gut passage times were observed for different food matrices by determining ileostomal folate excretion in 2 h intervals. Around 90% of the folate from the oral doses was recovered in the collected body fluids, plasma and stomal effluent, by 10 h postdose, independent of the size of the administered folate doses of 200 or 400 mg (0.4 or 0.9 mmol). Conclusion: The results imply that this model provides a suitable tool to estimate folate bioavailability from foods. Keywords: Folate absorption; folate in ileostomal effluent; ileostomists; plasma folate kinetics; urinary folate excretion

Chloroquine: Physiological Basis of Drug Resistance in Plasmodium berghei

Mouse erythrocytes, parasitized by chloroquine-sensitive plasmodia, concentrate this drug in vivo to levels over twice as high as erythrocytes parasitized by chloroquine-resistant plasmodia; nonparasitized red cells accumulate little chloroquine. Selective toxicity of this drug may depend upon a special drug-concentrating mechanism of plasmodic impairment of such mechanism.
Protective Action of Polycyclic Hydrocarbons against Induction of Adrenal Necrosis by Dimethylbenzanthracene

Treatment of rats with certain polycyclic hydrocarbons shifts the hydroxylation of dimethylbenzanthracene (DMBA) by liver microsomes from the side-chain to the ring. Protection by these hydrocarbons against dimethylbenzanthracene-induced adrenal necrosis is possibly achieved by decreasing the yield of the 7-hydroxymethyl derivative of dimethylbenzanthracene which may act as the necrotic agent by virtue of its strutctural resemblance to the adrenocortical steroids.
Workplace Bullying and Work Engagement: A Self-Determination Model

This study modeled motivational mechanisms that explain the negative effects of workplace bullying on work engagement. Guided by self-determination theory, workplace bullying was predicted to decrease worker engagement indirectly, due to the denial of employees’ basic psychological needs and their intrinsic motivation to work. From a sample of 243 full-time employees, serial multiple mediation models revealed that the indirect relationships between workplace bullying and work engagement (i.e., vigor, dedication, absorption) were serially mediated by basic psychological needs and intrinsic motivation to work. In support of self-determination theory, this study revealed that workplace bullying indirectly disengages employees from their work by denying them of their autonomy and relatedness needs and thwarting their motivation to perform work in a fulfilling way.
Applying models of visual search to menu design

The Guided Search (GS) model, a quantitative model of visual search, was used to develop menu designs in a four-step process. First, a GS simulation model was defined for a menu search task. Second, model parameters were estimated to provide the best fit between model predictions and experimental data. Third, an optimization algorithm was used to identify the menu design that minimized model predicted search times based on predefined search frequencies of different menu items. Fourth, the design was tested. The results indicate that the GS model has the potential to be part of a system for predicting or automating the design of menus. # 2002 Elsevier Scince Ltd.
An Analysis of the Relationship Between High School Students’ Tendency Toward Violence, Self-Esteem, and Competitive Attitude

This study analyzes the relationship among high school students’ tendencies toward violence, self-esteem, and competitive attitudes. It was conducted in Fethiye, Muğla, between September 2013 and January 2014. The population of the study consisted of 6,531 students from 11 high schools. The participants were determined using stratified random sampling, and the study data were collected from 1,600 students. A personal information form, the Violence Tendency Scale, the Competitive Attitude Scale, and the Coopersmith Self-Esteem Scale were used as data collection tools. In this study, the rate of the participants who were exposed to violence was 15.4%. Of them, 46.2% said that one of their family members was violent toward them, while 27.3% said that their teachers had been violent toward them. Of the participants that were exposed to violence, 55.8% reported psychological violence, 27.3% reported physical violence, and 10.8% reported sexual violence. In the study, tendency toward violence is a dependent variable, while competitive attitude and self-esteem are independent variables. Family type, exposure to violence, and demographics are control variables. Age, class, school, family attitude, and exposure to violence are the variables that created significant differences in the tendency for violence. The present study showed that there was an inverse and weak yet significant relationship between the students’ tendencies toward violence and competitiveness (r = −.169), and a positive and weak relationship between tendency toward violence and self-esteem (r = .238). Also, there was an inverse and low-level significant relationship between competitiveness and self-esteem (r = −.121). The variables which affect the tendency toward violence are gender, exposure to violence, competitiveness, age, self-esteem, and extended family type in a descending order regarding their importance. The predictive power of the variables on the tendency toward violence was 16.8%, which is not statistically significant.
Intimate Partner Violence and Controlling Behavior Among Male Same-Sex Relationships in China: Relationship With Ambivalent Sexism

In this study, we examined intimate partner violence (IPV), cold violence, and controlling behaviors in male same-sex relationships in China, with a focus on the characteristics of IPV and controlling behaviors, and their relationships with ambivalent sexism. IPV was categorized as psychological aggression, physical injury, physical assault, and sexual coercion and was measured using the revised Conflict Tactics Scales (CTS2), an eight-item scale measuring cold violence that was designed specifically for this study. Controlling behaviors were measured using a 34-item scale that was designed for this study, and sexist attitudes toward women and men were assessed using the short forms of the Ambivalent Sexism Inventory (ASI) and the Ambivalence toward Men Inventory (AMI), respectively. Participants (N = 272) reported instances of perpetration of or victimization by IPV and controlling behaviors within the past 6 months and indicated ambivalent sexism (hostile attitude toward men and women and benevolent attitude toward men and women [HM, HS, BM, and BS, respectively]). Almost 47.1% of the participants reported an experience of IPV, and the prevalence of cold violence and controlling behaviors was found to be 65.1% and 80.5%, respectively. Psychological aggression was the most common, followed sequentially by sexual coercion, physical assault, and injury in present study. We found a strong association between perpetration and victimization and that different forms of violence tend to co-occur in both IPV and controlling behaviors. As predicted, ambivalent sexism was positively correlated with IPV and controlling behaviors, specifically HS and HM. The results indicated the high prevalence of IPV and controlling behaviors among male same-sex relationships, and sexism contributing to this high prevalence.
Is There a Cumulative Association Between Adverse Childhood Experiences and Intimate Partner Violence in Emerging Adulthood?

Adverse childhood experiences (ACEs) have been shown to cumulatively predict a range of poor physical and mental health outcomes across adulthood. The cumulative effect of ACEs on intimate partner violence (IPV) in emerging adulthood has not been previously explored. The current study examined the individual and cumulative associations between nine ACEs (emotional abuse, physical abuse, sexual abuse, emotional neglect, physical neglect, witnessing domestic violence, living with a mentally ill, substance abusing, or incarcerated household member) and IPV in a diverse sample of college students (N = 284; Mage = 20.05 years old [SD = 2.5], 32% male, 37% Caucasian, 30% Asian, 33% other, and 27% Hispanic) from an urban, public college in the Northeast of the United States. Participants reported ACEs (measured by the Adverse Childhood Experiences Survey) and IPV perpetration and victimization (measured with the Revised Conflict Tactics Scale–2) of physical and psychological aggression in an online study that took place from 2015 to 2016. Bivariate and multivariate associations between ACEs, cumulative ACEs (assessed by the sum of adverse experiences), and IPV outcomes were assessed, while controlling for demographics and socioeconomic status. No cumulative associations were observed between ACEs and any of the IPV subscales in multivariate regressions, while witnessing domestic violence was significantly associated with perpetration and victimization of physical aggression and injury, and household member incarceration and physical abuse were associated with physical aggression perpetration. Adverse childhood events do not seem to associate cumulatively with IPV in emerging adulthood and the contributions of individual childhood experiences appear to be more relevant for IPV outcomes. Clinical and research implications are discussed.
Validation of the English Language Version of the Violent Ideations Scale

This study used a within-participant design to evaluate the concurrent validity and test–retest reliability of the Violent Ideations Scale in a general population, English-speaking opportunistic sample. Data from 116 adult participants (M age = 33.7, SD = 11.9, male = 30 [25.9%]) were used to compare scores on the Violent Ideations Scale and Aggression Questionnaire and responses to the Schedule of Imagined Violence. A subgroup of 27 participants (M age = 37.2, SD = 13.6, male = 8 [29.6%]) completed the Violent Ideations Scale on a second occasion, 2 weeks later. The Violent Ideations Scale was found to correlate significantly with the Aggression Questionnaire subscale and total scores, with the strongest correlations being with physical aggression and total scores. Participants were more likely to be categorized as having experienced a violent ideation based on responses to the Violent Ideation Scale, compared with the Schedule of Imagined Violence, most likely due to the Schedule of Imagined Violence underestimating the prevalence of violent ideation. A significant, strong correlation was found between total Violent Ideations Scale scores at Time 1 and Time 2. Overall, the Violent Ideations Scale was found to have concurrent validity when compared with the Aggression Questionnaire and good test–retest reliability, suggesting that it would be suitable for use with a nonclinical, English-speaking sample.
A Variable Typed Logic of Effects

In this paper we introduce a variable typed logic of effects inspired by the variable type systems of Feferman for purely functional languages. VTLoE (Variable Typed Logic of Effects) is introduced in two stages. The first stage is the first-order theory of individuals built on assertions of equality (operational equivalence a la Plotkin), and contextual assertions. The second stage extends the logic to include classes and class membership. The logic we present provides an expressive language for defining and studying properties of programs including program equivalences, in a uniform framework. The logic combines the features and benefits of equational calculi as well as program and specification logics. In addition to the usual first-order formula constructions, we add contextual assertions. Contextual assertions generalize Hoare′s triples in that they can be nested, they can be used as assumptions, and their free variables can be quantified. They are similar in spirit to program modalities in dynamic logic. We use the logic to establish the validity of the Meyer Sieber examples in an operational setting. The theory allows for the construction of inductively defined sets and derivation of the corresponding induction principles. We hope that classes may serve as a starting point for studying semantic notions of type. Naive attempts to represent ML types as classes fail in the sense that ML inference rules are not valid.
Prediction-Based Admission Control for IaaS Clouds with Multiple Service Classes

There is a growing adoption of cloud computing services, attracting users with different requirements and budgets to run their applications in cloud infrastructures. In order to match users' needs, cloud providers can offer multiple service classes with different pricing and Service Level Objective (SLO) guarantees. Admission control mechanisms can help providers to meet target SLOs by limiting the demand at peak periods. This paper proposes a prediction-based admission control model for IaaS clouds with multiple service classes, aiming to maximize request admission rates while fulfilling availability SLOs defined for each class. We evaluate our approach with trace-driven simulations fed with data from production systems. Our results show that admission control can reduce SLO violations significantly, specially in underprovisioned scenarios. Moreover, our predictive heuristics are less sensitive to different capacity planning and SLO decisions, as they fulfill availability SLOs for more than 91% of requests even in the worst case scenario, for which only 56% of SLOs are fulfilled by a simpler greedy heuristic and as little as 0.2% when admission control is not used.
Clustering and Managing Data Providing Services Using Machine Learning Technique

In service-oriented computing, a user usually needs to locate a desired service for (i) fulfilling her requirements, or (ii) replacing a service, which disappears or is unavailable for some reasons, to perform an interaction. With the increasing number of services available within an enterprise and over the internet, locating a service online may not be appropriate from the performance perspective, especially in large internet-based service repositories. Instead, services usually need to be clustered offline according to their similarity. Thereafter, services in one or several clusters are necessary to be examined online during dynamic service discovery. In this paper we propose to cluster data providing (DP) services using a refined fuzzy C-means algorithm. We consider the composite relation between DP service elements (i.e., input, output, and semantic relation between them) when representing DP services in terms of vectors. A DP service vector is assigned to one or multiple clusters with certain degrees. When grouping similar services into one cluster, while partitioning different services into different clusters, the capability of service search engine is improved significantly.
Modification of Motivated Behavior Elicited by Electrical Stimulation of the Hypothalamus

Previous reports demonstrated that hypothalamic stimulation may elicit either eating, drinking, or gnawing and emphasized both the specificity of the neural circuits mediating these behaviors and the similarity to behavior during natural-drive states such as hunger and thirst. We find that, after a period of very consistent elicitation of one of these behaviors, the animal may exhibit an equally consistent alternate behavior. A learning component is implicated in the association of hypothalamic stimulation with a particular behavior pattern.
Review of the Current ACS Practice Guideline to Develop an Ischemic Chest Pain Protocol

This review covers the major recommendations to the 2000 American College of Cardiology/American Heart Association (ACC/AHA) Acute Coronary Syndromes (ACS) Practice Guidelines. This review describes the evidence-based medicine that rationalizes the recommended pharmacotherapy for ST elevation myocardial infarction (STEMI) and non- STEMI (NSTEMI) ACS. To ensure conformity, an Ischemic Chest Pain Protocol (ICPP) order form was developed. The ICPP is like a menu that includes orders for all the recommended therapies in an easy-to-use checklist format. The ICPP has facilitated the implementation, acceptance, and understanding of the 2002 ACC/AHA ACS practice guidelines. Hence with improved conformity, it is hoped that the improved outcomes that were intended will result. A description of the ICPP and a mechanism for implementation is provided in this article.
