Factors affecting viewing time of pornography.

Summary This study attempted to test the hypothesis that as erotic stimuli became more explicit and pornographic, the amount of time subjects would spend looking at them would first increase and then decrease. It was also expected that looking time would be shorter when the slides were viewed in the presence of observers than when they were viewed alone. Forty male subjects saw a series of 15 slides and rated them on a number of dimensions. The subjects could view each slide as long as they liked. Half the subjects viewed the slides alone; the other half were observed by three “graduate students interested in the experiment. ” In addition, half the subjects in each group viewed the slides in ascending order of previously rated pornography value, the other half viewed them in random order. As expected, viewing times were significantly shorter in the audience condition. In the alone condition looking times increased as the slides were rated as more pornographic. The failure to obtain the expected curvilinear.
Contrasting in vivo and in vitro fates of glioblastoma cell subpopulations with amplified EGFR

Despite the high incidence of EGFR amplification in patient glioblastoma multiforme (GBM) tissues, only a single GBM cell line, of the many described in the literature, is known to contain and maintain amplified EGFR. Because EGFR mutations in GBM manifest primarily, if not exclusively, in amplified form, it follows that the availability of cell lines with mutation of endogenous EGFR would also be in short supply. In fact, there are no GBM cell lines harboring the common EGFR mutants described in patient GBMs. These observations suggest that in vivo environments select for EGFR amplification, whereas in vitro environments, specifically cell cultures, select against this gene alteration. To contrast directly the fates of EGFR amplification in vivo and in vitro, as well as to examine potential relationships between EGFR amplification and mutation, we have established and maintained GBM explants as xenografts by serial passaging in nude mice. Analysis of EGFR copy number and EGFR mutation status in 11 patient tumors and their corresponding xenografts, as well as the monitoring of EGFR copy number during the establishment of a GBM cell line from a xenograft with amplified EGFR, indicated that selection for EGFR amplification is an in vivo phenomenon. Furthermore, our data indicated that EGFR mutation occurs only in tumors with EGFR amplification and showed that the selection of amplified mutant EGFR over amplified wild‐type EGFR as a xenograft occurred rapidly and completely during tumor propagation. © 2003 Wiley‐Liss, Inc.
Complete blood count (CBC) are closely correlated with Plasmodium vivax density in district Bannu, Khyber Pakhtunkhwa, Pakistan

The current study was conducted in Women and Children Teaching Hospital (WCTH) district Bannu to correlate the Plasmodium vivax density on complete blood count (CBC). The study contained 137 blood samples of patients, who visited to the hospital with the complaints of fever, headache, abdominal pain and shivering. Among these 49 (35.766%) were found positive for P. vivax and 88 (64.233%) were found negative. Among the positive cases the male and female was recorded 65.306% and 34.693% respectively. The patients, who have less than ten years of age, were more infected by P. vivax. The maximum density in patients was recorded four per field in microscope but the density two were more abundant. The parasite density decreased with the increase in WBCs count. Similarly the platelets count increases when parasite density decreases. The maximum P. vivax density reduce the WBCs and platelets count which may weaken the immune system and the person exposed to other pathogens like salmonella, hepatitis viruses and other diarrhea causing agents etc. Furthermore the study helps us for the improvement of malaria control and other strategic plan among the population of district Bannu.
Non-balanced endogenous growth and structural change : when

We propose a model of non-balanced endogenous growth in which the final good, which can be either consumed or used as capital, is produced using two intermediate inputs, one being “knowledge-intensive”. Agents working in the knowledge-intensive sector need to accumulate technological knowledge and thus have to decide how to split their individual unit of time between accumulation of technological knowledge (research) and work. Agents working in the second sector do not need to accumulate knowledge and thus devote all their individual unit of time to work. Individual knowledge therefore becomes a labor-augmenting factor, and knowledge accumulation leads to an unbounded increase in TFP in the knowledge-intensive sector, and thus to endogenous capital deepening. The asymmetry in the growth rates of TFP leads to non-balanced growth. Labor (number of workers) reallocations across sectors occur, leading to a greater increase in output for the knowledge-intensive sector. We show that non-balanced growth is consistent with Kaldor facts, as the asymptotic equilibrium is above all characterized by a constant interest rate and capital share in national income. However, the economy follows a growth path converging to a particular level of wealth that depends on the initial price of capital and knowledge. As a consequence, countries with the same fundamentals but lower initial wealth will be characterized by lower asymptotic wealth. We therefore extend the Lucas [19] finding and prove the existence of non-convergence across countries in a framework with structural change.
Oral Administration of Hapten Inhibits In Vivo Induction of Specific Cytotoxic CD8+ T Cells Mediating Tissue Inflammation: A Role for Regulatory CD4+ T Cells1

We investigated whether oral tolerance could block the development of an inflammatory response mediated by CD8+ T cells, using a mouse model of oral tolerance of contact sensitivity (CS) to the hapten 2,4-dinitrofluorobenzene (DNFB). In this system, the skin inflammatory response is initiated by hapten-specific class I-restricted cytotoxic CD8+ T (CTL) cells, independently of CD4 help. Oral delivery of DNFB before skin sensitization blocked the CS response by impairing the development of DNFB-specific CD8+ effector T cells in secondary lymphoid organs. This was shown by complete inhibition of DNFB-specific CTL and proliferative responses of CD8+ T cells, lack of specific IFN-γ-producing CD8+ T cells, and inability of CD8+ T cells to transfer CS in RAG20/0 mice. RT-PCR and immunohistochemical analysis confirmed that recruitment of CD8+ effectors of CS in the skin at the site of hapten challenge was impaired in orally tolerized mice. Sequential anti-CD4 Ab treatment showed that only depletion of CD4+ T cells during the afferent phase of CS abrogated oral tolerance induction by restoring high numbers of specific CD8+ effectors in lymphoid organs, whereas CD4 depletion during the efferent phase of CS did not affect oral tolerance. These data demonstrate that a single intragastric administration of hapten can block in vivo induction of DNFB-specific CD8+ CTL responsible for tissue inflammation and that a subset of regulatory CD4+ T cells mediate oral tolerance by inhibiting expansion of specific CD8+ effectors in lymph nodes.
Post-mortem concentrations of hypoxanthine in the vitreous humor — a comparison between babies with severe respiratory failure, congenital abnormalities of the heart, and victims of sudden infant death syndrome

Post-mortem hypoxanthine concentrations in the vitreous humor of human infants were investigated. Hypoxanthine is formed from hypoxic degradation of adenosine monophosphate. The concentrations in the vitreous humor can give information about antemortem hypoxia. The post-mortem levels were corrected for the time elapsing between death and the autopsy. Four groups of infants were compared: 17 babies who died of respiratory distress syndrome (RDS), 72 infants who died of sudden infant death syndrome (SIDS), 23 children dying of congenital heart disease (both cyanotic and acyanotic), and 15 children dying acutely in accidents without any known significant time of hypoxia before death. The corrected, median hypoxanthine levels in victims of SIDS (200 mumol/L) was significantly higher (p < 0.01) than in the accident group (0 mumol/L), but no clear difference was found between the SIDS group and the RDS group (101 mumol/L), or the heart group (54 mumol/L). A number of children with "normal" hypoxanthine levels (0 to 38 mumol/L) were found in all four groups, but the numbers were significantly lower (p < 0.005) in the RDS, SIDS and heart groups than in the accident group. It is concluded that SIDS is probably not a sudden event, but may be preceded by relatively long, or repeated intermittent periods of hypoxia (of unknown etiology).
Propagation modeling of indoor wireless communications at 60 GHz

In this paper, based on a 3D ray-tracing analysis, statistical parameters (i.e. mean excess delay and rms delay spread) for site-specific indoor environments were extracted. The fading statistics of these indoor environments were shown to obey a Weibull distribution. As is well-known, fading statistics are necessary for predicting channel capacity limit and this were presented in the conference
A Case of Severe Chronic Progressive Axonal Polyradiculoneuropathy Temporally Associated With Anti-CV2/CRMP5 Antibodies

Objectives: The involvement of the peripheral nervous system by anti-CV2/CRMP5 paraneoplastic antibodies is typically encountered as a mixed sensorimotor polyneuropathy. We report a fatal case of severe chronic progressive axonal polyradiculoneuropathy in association with this antibody. Methods: Review of the patient's chart, nerve conduction/electromyographic studies, and nerve biopsy. Results: A 51-year-old man presented with a progressive quadriparesis over a 4-month period. Extensive evaluation for potential etiologies was significant only for positive anti-CV2/CRMP5 antibodies without detection of an underlying neoplasm. Despite multiple immunomodulatory therapies, the patient progressed and demonstrated electrodiagnostic evidence for a chronic axonal polyradiculoneuropathy with ongoing denervation. The patient eventually died of respiratory failure. Conclusions: This case adds to the clinical spectrum of the peripheral nervous system involvement in patients with paraneoplastic anti-CV2/CRMP5 antibodies.
High -performance work practices and employee attitudes: Evidence from hotel industry in Sri Lanka

In this contemporary world, most of the organizations understand the importance of managing human resources effectively and efficiently to become successful. Many Previous researches have established a significant relationship between High performance Human resource (HR) practices and firm level and individual level outcomes. Few studies have considered the important role of employee perceived HR practices and outcome of high performance HR practices and its mediating roles. To address the recent growing interest in the literature for an investigation of this nature, this study was conducted investigating the relationship between high-performance work practices and employee attitudes in the hotel industry of Sri Lanka. Questionnaire was used to collect the data. Initially discussion was conducted with 200 employees who voluntarily participated in this study from Hotel sector, finally 175 participants agreed to fill out the questionnaire. Of the selected sample 150 questionnaires was complete and usable for this study. Correlation and regression analysis was performed to test the hypothesized relationship. Results of the study showed that high -Performance work practices positively related with intention to remain with organization, further study found positive relationship between employees’ perceptions of high-performance work practices and affective commitment; furthermore, study found that affective commitment mediated the relationship between high performance work practices and intention to remain with organization. On the basis of these findings, managerial implications of the study and future research direction were highlighted.
Vitamin C Status of Elderly Patients on Admission into an Assessment Geriatric Ward

A study of the plasma vitamin C concentration in patients in an assessment geriatric ward was carried out for 1 year. The incidence of vitamin C deficiency, as reflected by the plasma vitamin C level was 40.1%. There was almost no difference in its prevalence amongst the sexes or various age groups, but the incidence of vitamin C deficiency was highest in patients admitted from institutions. Furthermore, this study also revealed that patients with certain illnesses were more vulnerable to vitamin C deficiency than other patients and the standard hospital diet alone was not sufficient to improve the vitamin C status of these patients in the short-term.
Vertical Price Transmission in Local Rice Markets in Côte d’Ivoire: Are Consumers Really Right?

This paper analyses vertical relationships between wholesale and retail prices in three local rice markets in Cote d’Ivoire. The aim of the paper is to ascertain whether the popular complaint of consumers about the asymmetric price transmission holds true. Our empirical analysis makes use of threshold cointegration and error correction models and monthly data for the period 1990-1999. We found that wholesale and retail prices are cointegrated and increases in wholesale prices are passed on to retail prices more quickly than decreases.
Functional polymorphisms of the leptin and leptin receptor genes are associated with longevity and with the risk of myocardial infarction and of type 2 diabetes mellitus.

INTRODUCTION Longevity is commonly associated with good health and with delayed onset of age-related diseases with usually benign course. Leptin (LEP) significantly affects metabolism and numerous functions of the organism. To find out if extreme longevity and its phenotype are associated with genetic variants of leptin and leptin receptor (LEPR) genes, we analysed the frequencies of the -2548 G/A and +19 G/A LEP, as well as the K109R, Q223R, and K656N LEPR polymorphisms in centenarians and in control groups. MATERIAL AND METHODS The frequencies of the LEP and LEPR polymorphisms were tested by restriction fragment length polymorphism in 128 centenarians, 414 young controls (Y), 226 myocardial infarction (MI) patients, and 190 type 2 diabetes mellitus (DM2) patients. RESULTS The GG genotype of the -2548 G/A LEP polymorphism was significantly more common in centenarians than in the Y, MI and DM2 groups (p = 0.048, p = 0.003, p = 0.049, respectively). In addition, the AA genotype of the K109R LEPR polymorphism was significantly less frequent in centenarians than in the Y, MI, and DM2 groups (p = 0.026, p = 0.013, and p = 0.001, respectively). CONCLUSIONS We suggest that the leptin pathway plays a role in the regulation of longevity, possibly by modulating the risk of development of MI and of DM2.
Factors affecting fertility in a commercial frozen semen insemination program

Timing of insemination, mare selection and stallion fertility has been described as important factors in the successful outcome in the use of frozen semen [1,2]. Other factors such as use of hormones and different treatment regimens have as well been described with the use of frozen thawed semen as well as with the use of fresh and cooled semen [2]. In order to optimize the use of frozen-thawed semen, a study was performed to identify factors influencing the pregnancy results following insemination with frozen-thawed semen in a Danish equine practice.
Clinical efficacy of laparoscopic hepatectomy and its effects on cellular immune function

Objective: To investigate the clinical efficacy of laparoscopic hepatectomy and its effects on organism cellular immune function. Methods: Two hundred liver cancer patients cured in our hospital from January 2013 to December 2016 were enrolled in this study and randomly divided into observation group and control group, with 100 cases in each group. The patients in the observation group were treated with laparoscopic hepatectomy, while patients in the control group were treated with open hepatectomy. Various intraoperative indexes, postoperative short-term and long-term efficacy, occurrence of complications, ratio of CD3+ T lymphocytes and their subsets (CD4+ and CD8+) at different time points before and after operation, as well as expression levels of serum interleukin-6 (IL6) and tumor necrosis factor-α (TNF-α) in two groups of patients were compared. Results: The operation time of the observation group was longer than that of the control group; total bleeding volume and blood occlusion rate were less than those of the control group; incision length was shorter than that of the control group. Compared with the control group, the indwelling time of the drainage tube, time to start eating and postoperative hospital stays of the patients in the observation group were significantly less than those in the control group. Compared with the control group, 24 h and 72 h after operation, the indexes of AST, ALT and TBIL of the patients in the observation group markedly reduced, while ALB level obviously increased (P<0.05), which was statistically significant. There were no statistical differences of postoperative metastasis rate, relapse rate and mortality between the two groups, but the incidence of complications in the observation group was significantly lower than that in the control group (P<0.05). At postoperative 72 h, the ratio of CD3+ T lymphocytes and their subsets (CD4+ and CD8+) cell populations in the observation group was basically recovered to the preoperative level (P>0.05), while those in the control group were remarkably lower than the preoperative level (P<0.05). Compared with the preoperative condition, the levels of IL-6 and TNF-α in the control group increased 24 h and 72 h after operation (P<0.05); in the observation group, those two levels increased 24 h after operation (P<0.05), but there was no significant difference at 72 h and pre-operation (P>0.05). Conclusion: Laparoscopic hepatectomy for liver cancer had definite clinical efficacy, small trauma, high security, low incidence of complications, little impact on patients’ cellular immune function and rapid postoperative recovery.
Outward currents of single hippocampal cells obtained from the adult guinea‐pig.

1. Neurones were isolated from the hippocampus of adult guinea‐pigs by enzymatic and mechanical treatment. The electrophysiological properties of these cells were examined immediately after dissociation by intracellular recordings using low‐resistance electrodes (2‐5 M omega). 2. Pyramidal‐shaped cells were identified visually. Intracellular recordings showed that these cells have input resistances ranging from 200 to 1300 M omega. Passive voltage responses to hyperpolarizing current injection were fitted by single exponentials decaying with time constants ranging from 15 to 60 ms. This suggests that the electrotonic structure of these cells is compact such that injected current elicited isopotential intracellular responses. 3. Outward currents activated by depolarization were examined in these cells using voltage‐clamp techniques. The amplitude and the time course of the outward currents were profoundly affected by the holding potential. For cells held at ‐50 mV or more positive, depolarizing steps produced a slowly rising outward current. At holding potentials negative to ‐55 mV depolarizing pulses produced an additional early transient outward current followed by a slowly rising component which decayed gradually during sustained depolarizations. 4. The outward currents were separated by their kinetic properties and their sensitivity to cobalt (Co2+), tetraethylammonium (TEA) and 4‐aminopyridine (4‐AP). 5. The transient current peaked within 6 ms of the onset of depolarizing pulses. It decayed exponentially with a time constant of 20‐40 ms. The amplitude of the current activated by a fixed depolarization increased gradually as the duration or the amplitude of the hyperpolarizing pre‐pulse increased. The current activated by a fixed depolarization reached its half‐maximal level when the hyperpolarizing pre‐pulse was at ‐83 mV. 6. 4‐AP exerted two actions on the transient current. Firstly, the time constant of the falling phase decreased by about a factor of two. Secondly, the current was blocked in a time‐ and voltage‐dependent manner: the block increased when the hyperpolarizing pre‐pulse lengthened. TEA, up to 10 mM, did not affect the amplitude of the transient current. Co2+ suppressed this current. The effects of Co2+ consisted of a shift to the positive direction of the voltage dependence of the current. 7. The delayed currents can be divided into Ca2+‐dependent and Ca2+‐independent components. The component persistent in the Co2+ solution (K‐current) decayed slowly with maintained depolarization (time constant greater than 3 s). (ABSTRACT TRUNCATED AT 400 WORDS)
Vertebrate Succession in the Ischigualasto Formation

ABSTRACT The Upper Triassic (Carnian—Norian) Ischigualasto Formation has yielded a diverse vertebrate fauna that records the initial phase of dinosaur evolution. Radioisotopic dates from ash layers within the formation provide a chrono-stratigraphic framework, and stratigraphic and sedimetological studies have subdivided the formation into four members and three abundance-based biozones. We describe two new basal dinosauromorphs, an unnamed lagerpetid and a new silesaurid, Ignotosaurus fragilis, gen. et sp. nov., which increase to 29 the number of vertebrates in the Ischigualasto fauna. We provide a census of 848 fossil specimens representing 26 vertebrate taxa logged to stratigraphic intervals of 50 m. This temporally calibrated census shows that abundance and taxonomic diversity within the Ischigualasto Formation does not change suddenly but rather appears to gradually decline in response to climatic deterioration. The only abrupt shift in faunal composition occurs at the end of the second of three biozones, when the abundant cynodont Exaeretodon is replaced by the rare dicynodont Jachaleria.
Paramagnetic Resonance

After a brief introduction a general account is given of the main phenomena associated with electronic magnetic resonance. Two chapters on line width and experimental technique review the problems involved in detection of the resonance phenomena. A short account of the theory of paramagnetism of the solid state follows, leading to a derivation of the spin-Hamiltonian. The importance of the latter as a method of describing the resonance results is emphasized, the discussion proceeding in terms which are, as far as possible, independent of the underlying theory. The ions of the iron (3d) group and the rare earth (4f) group are then surveyed individually in terms of the spin-Hamiltonian. The influence of exchange interaction is treated in a separate chapter, and the review ends with a brief account of resonance in gases and other special compounds.
