HOSTIGAMIENTO SEXUAL LABORAL EN TRABAJADORES DE VIGILANCIA DE UNA EMPRESA ELECTRÓNICA

Introduccion: Mexico ha firmado acuerdos internacionales a favor de la erradicacion de cualquier tipo de violencia en el trabajo y particularmente respecto al acoso sexual. La legislacion federal, en el Codigo Penal Federal se encuentra tipificado el delito el hostigamiento sexual, que solamente sera punible cuando se cause un perjuicio o dano, y que solo se procedera contra el hostigador a peticion de parte ofendida. Por lo que la presente investigacion ofrece un cuestionario metodologicamente construido para su identificacion en las primeras manifestaciones. Metodos. Estudio en dos fases: I) entrevistas a profundidad para la validez de contenido y II) diseno transversal analitico para la validez de constructo. En la primera fase se entrevistaron a 12 trabajadores identificados como hostigadores sexuales o victimas de estos comportamientos, para elaborar los enunciados que conformaron el cuestionario. Posteriormente, se valido su construccion en 74 trabajadores de vigilancia empresarial. Resultados. Se llevo a cabo el analisis factorial y determino 22 items adecuados, en tres dimensiones: ambiental, emocional y verbal; el 77% de la varianza explicada y 0.80 confiabilidad alpha de Cronbach. Ademas, se construyeron 11 items que valoraron consecuencias y siete mas que indican los procedimientos preventivos en la empresa con formato dicotomico. Finalmente, se evaluo a los trabajadores y el 20% de los trabajadores identifico riesgo, el 7%, consecuencias personales e impacto en la actividad laboral por hostigamiento sexual perpetrado por superiores. Conclusion. El diseno del cuestionario de hostigamiento sexual fue psicometricamente valido, de facil aplicacion y calificacion para implementarse en las politicas preventivas de riesgos psicosociales en el ambito laboral.
The anterior lens capsule used as support material in RPE cell-transplantation.

PURPOSE To investigate the use of an ocular basement membrane as support material for transplanted porcine RPE cells. METHODS Porcine RPE cells were grown on bovine corneal extracellular matrix (ECM), isolated bovine- and porcine lens capsules, and tissue culture plastic. Cell density, and cell morphology were studied by phase contrast microscopy and transmission electron microscopy. RESULTS RPE cells grown on porcine anterior lens capsule and on ECM obtained better morphology and higher final cell density than cells grown on plastic and on bovine anterior lens capsule. It was possible to transplant the porcine anterior lens capsule to the subretinal space in pigs. Within two weeks of observation, the lens capsule was well tolerated in the subretinal space. CONCLUSION The anterior lens capsule seems to be promising as support material for use in RPE cell-transplantation.
Machine Learning in Vulnerability Databases

We mainly introduce the application of machine learning in vulnerability databases. By analysing an existing open source vulnerability database, we extract relevant attributes and construct lists of the attributes, then mining the attribute lists using machine learning technology, hope to discover some knowledge which is novel, interesting and of value to researchers. We only mine the association rules in a vulnerability database in this paper. Through these association rules, we can discover some co-oocurring vulnerability attributes, which can be further inferred laws of vulnerabilities.
Recovery, Preparation, Storage and Utilization of Spermatozoa for Fertility Preservation in Cancer Patients and Sub-Fertile Men

Sperm cryopreservation is an important part of an infertility program for patients undergoing infertility treatments, fertility assurance for vasectomy cases, and for fertility preservation due to cancer or other medical conditions. With recent developments in reproductive technology, even men with severely impaired sperm parameters can benefit from cryopreservation as procedures such as intra-cytoplasmic sperm injection (ICSI) require only a few sperm to achieve fertilization and pregnancy. The increasing success of cancer treatment and concerted efforts to ensure quality of life after successful treatment have placed great emphasis on the need to preserve the reproductive capability of young men. It is a highly effective method of protecting male fertility potential, and involves collection, freezing, and long-term storage of sperm. Based on the etiological condition of the patients, sperm can be collected by ejaculation or by surgical retrieval from epididymis or testes. The option to bank sperm should.
Miniaturized Triple-Band Antenna With a Defected Ground Plane for WLAN/WiMAX Applications

A miniaturized multifrequency antenna is proposed. The proposed antenna can generate three separate impedance bandwidths to cover all the 2.4/5.2/5.8-GHz WLAN operating bands and the 2.5/3.5/5.5-GHz WiMAX bands. The proposed microstrip-fed antenna mainly consists of a circular ring, a Y-shape-like strip, and a defected ground plane. By adding a Y-shape-like strip in the circular ring, the antenna excites two resonant modes and is with miniaturization structure. Because of the introduction of the cambered ground plane with an isosceles triangle-defect, the third wide band with better impedance matching is obtained. A prototype is experimentally tested, and the measured results show good radiation patterns and enough gains across the operation bands.
Performance Analysis of $M$-PSK/ $M$-QAM Modulated Orthogonal Space–Time Block Codes in Keyhole Channels

It is known that the keyhole or pinhole effect can severely degrade the performance of multiple-input-multiple-output (MIMO) communication systems. In this paper, the outage probability and error probability of orthogonal space-time block codes with <i>m</i> transmit and <i>n</i> receive antennas over keyhole fading channels are analyzed. Closed-form outage probability and symbol/bit error rate expressions are derived with <i>M</i>-ray phase-shift keying (<i>M</i>-PSK) and <i>M</i>-ray quadrature amplitude modulation (<i>M</i>-QAM) signaling. It is found that the exact error probability expressions have two different forms for <i>m</i> = <i>n</i> and <i>m</i> ne <i>n</i>, respectively. Furthermore, when <i>m</i> ne <i>n</i>, approximate error rate expressions are derived at high signal-to-noise ratios (SNRs), whereas there are no asymptotic expressions for <i>m</i> = <i>n</i>. Simulation results are provided to verify our analytical results.
Presence of the Tet M Determinant in a Clinical Isolate of Acinetobacter baumannii

ABSTRACT The tet(M) gene encodes a protein which is related to tetracycline ribosomal protection, one of the mechanisms of tetracycline resistance. A tet(M) gene that is 100% homologous to the tet(M) gene of Staphylococcus aureus has been found in a clinical isolate of Acinetobacter baumannii, which also carries the tet(A) gene encoding a tetracycline efflux pump.
An Opportunistic Channel Quality Feedback Scheme for Proportional Fair Scheduling

In this paper, we propose a channel quality information (CQI) feedback load reduction scheme for proportional fair scheduling (PFS) in wireless systems. The proposed scheme induces select users to feed back CQI only when the probability of selection is high. It is shown that the proposed scheme achieves system throughput comparable to the conventional scheme, where each and every user feeds back its CQIs, with significant feedback load reduction for each of the users.

The Vac14-interaction Network Is Linked to Regulators of the Endolysosomal and Autophagic Pathway*

The scaffold protein Vac14 acts in a complex with the lipid kinase PIKfyve and its counteracting phosphatase FIG4, regulating the interconversion of phosphatidylinositol-3-phosphate to phosphatidylinositol-3,5-bisphosphate. Dysfunctional Vac14 mutants, a deficiency of one of the Vac14 complex components, or inhibition of PIKfyve enzymatic activity results in the formation of large vacuoles in cells. How these vacuoles are generated and which processes are involved are only poorly understood. Here we show that ectopic overexpression of wild-type Vac14 as well as of the PIKfyve-binding deficient Vac14 L156R mutant causes vacuoles. Vac14-dependent vacuoles and PIKfyve inhibitor-dependent vacuoles resulted in elevated levels of late endosomal, lysosomal, and autophagy-associated proteins. However, only late endosomal marker proteins were bound to the membranes of these enlarged vacuoles. In order to decipher the linkage between the Vac14 complex and regulators of the endolysosomal pathway, a protein affinity approach combined with multidimensional protein identification technology was conducted, and novel molecular links were unraveled. We found and verified the interaction of Rab9 and the Rab7 GAP TBC1D15 with Vac14. The identified Rab-related interaction partners support the theory that the regulation of vesicular transport processes and phosphatidylinositol-modifying enzymes are tightly interconnected.
Among very‐low‐birth‐weight neonates is red blood cell transfusion an independent risk factor for subsequently developing a severe intraventricular hemorrhage?

BACKGROUND: A severe intraventricular hemorrhage (IVH) in a preterm neonate can result in life‐long disabilities or death. Pathogenic mechanisms responsible for IVH are incompletely understood. We postulated that if the timing of a severe IVH could be approximated by serial ultrasound, potentially relevant antecedents could be identified.
The social structure and behaviour of Western Lowland gorillas (Gorilla gorilla gorilla) at Mbeli Bai, Republic of Congo

Most of what we know of the socioecology and behaviour of gorillas comes from studies of mountain gorillas (Gorilla beringei beringei), despite their representing less than 1 % of all gorillas in the wild. Western lowland gorillas (Gorilla gorilla gorilla) have received far less research effort, and difficulties in habituation have led previous studies to rely heavily on indirect trail evidence. This has prevented any in-depth comparison of social structure and behaviour between species. The discovery of swampy clearings frequented by western lowland gorillas in northern Congo has offered the first opportunity to obtain accurate demographic and behavioural data. This thesis reports on 6273 hours of observer presence at Mbeli Bai, which yielded 1681 hours of direct gorilla observation. Most data come from a popUlation of 13 groups and 7 solitary silverbacks. Group size ranged from 2 to 16 (mean = 8.4, SD 4.3) which does not differ significantly from data published on most other populations. Female natal and secondary transfer were recorded, and male emigration from the natal group appeared universal (no multi-silverback groups were recorded). No evidence of sub-grouping or a fission-fusion grouping pattern was found. During intra-group interactions, no evidence was recorded of female philopatry, and silverbacks herded and intimidated females (especially new immigrants) to prevent emigration. Inter-unit interactions took place on only 42% of shared bai-use occasions, and levels of silverback agonism were much lower than in mountain gorillas, with peaceful mingling of groups recorded. Display behaviour was common, and two previously unrecorded agonistic displays (the splash display and the crest display) are described. No contact aggression between silverbacks was observed but evidence of wounding sustained in the forest suggests that the bai environment may inhibit such aggression. High visibility and the ease of silverback 'policing' are thought to create an unusually tolerant social dynamic, and as such, frequencies of certain social behaviours should probably be viewed as site-specific. The thesis offers the fullest account of western gorilla social structure and behaviour to date. Long-term monitoring of life history variables, if continued, will provide an unparalleled opportunity to understand the effects of habitat and food availability and more stochastic influences on western gorilla social structure, fitness, and survival. 1

Optimale Diagnostik und Therapie der mikrovaskulären Angina pectoris

Abstract Patients with microvascular angina are characterized by angina pectoris with proof of myocardial ischemia in the absence of any relevant epicardial stenosis and without myocardial disease (type 1 coronary microvascular dysfunction according to Crea and Camici). Structural and functional alterations of the coronary microvessels (diameter < 500 µm) are the reason for this phenomenon. Frequently such alterations are associated with cardiovascular risk factors. Patients with angina pectoris without epicardial stenoses represent for 10 – 50 % of all patients undergoing coronary angiography depending on the clinical presentation. Diagnostic approaches include non-invasive (e. g. combination of coronary CT-angiography and positron emission tomography/echo Doppler-based coronary flow reserve measurements) as well as invasive procedures (coronary flow reserve measurements in response to adenosine, intracoronary acetylcholine testing). Pharmacological treatment of these patients is often challenging and should be based on the characterization of the underlying mechanisms. Moreover, strict risk factor control and individually titrated combinations of antianginal substances (e. g. beta blockers, calcium channel blockers, nitrates, ranolazine, ivabradine etc.) are recommended.
Aortic and hepatic contrast medium enhancement at CT. Part I. Prediction with a computer model.

PURPOSE To develop a physiologic model of contrast medium enhancement by incorporating available physiologic data and contrast medium pharmacokinetics and to predict organ-specific contrast medium enhancement at computed tomography (CT) with various contrast medium injection protocols in patients of variable height and weight. MATERIALS AND METHODS A computer-based, compartmental model of the cardiovascular system was generated by using human physiologic parameters and more than 100 differential equations to describe the transport of contrast medium. Blood volume, extracellular fluid volume, and regional blood flow were estimated from available data. Local structures were modeled mathematically to describe the distribution and dispersion of intravascularly administered iodinated contrast medium. A global model was formed by integrating regional circulation parameters with the models of local structures. Aortic and hepatic CT contrast-enhancement curves were simulated for three protocols and were compared with mean enhancement curves in three groups of 25-28 patients (80 patients total; 28 in one group, 25 in one group, and 27 in one group) receiving the same protocols. The percent difference in maximum enhancement between the simulated and empiric curves and the enhancement difference index (sum of the area difference between the simulated and empiric curves divided by the total area under the empiric curve) were computed. RESULTS The simulated and empiric enhancement curves closely agreed in maximum enhancement (the mean percent difference in the aorta was 7.4%; liver, 4.8%) and in variation over time (mean enhancement difference index in the aorta was 11.6%; liver, 12.7%). CONCLUSION A computer-based, physiologic model that may help predict organ-specific CT contrast medium enhancement for different injection protocols was developed. Such a physiologic model may have many clinical applications.
Diabetes and Deafness

The m.3243A>G mitochondrial DNA mutation is well known to be associated with deafness and diabetes, and patients presenting with these clinical features are routinely screened for this mutation. We wanted to assess whether this is a suitable screening strategy. We retrospectively reviewed the clinical notes of 242 patients who had attended a special mitochondrial clinic in the preceding 25-year period. Of the total 29 patients with mitochondrial disease presenting with deafness and diabetes, only 21 would have been correctly diagnosed by screening for the m.3243A>G mutation in blood or urine. Of the remaining eight patients, only six had other features suggestive of mitochondrial disease. We recommend that all patients with the combination of deafness and diabetes presenting to diabetes clinics be screened for the m.3243A>G mutation. In those patients in whom this test is negative, we recommend referral to a specialist neuromuscular clinic for further investigation. The association between maternally inherited diabetes and deafness and mitochondrial DNA (mtDNA) mutations is well recognized (1,2). Several mutations have been associated with this phenotype, including the m.3243A>G (3) and …
Dobutamine Infusion Modifies Thermoregulation During General Anesthesia

A redistribution of body heat from core to peripheral tissues causes a rapid decrease in core temperature.The present study tested whether a dobutamine infusion would facilitate redistribution and induce a further decrease in core temperature. Volunteers were randomly assigned to the control group (n = 8) and the experimental group (n = 8). They were anesthetized with isoflurane at an end-tidal concentration of near 1.2% for 120 min. In the experimental group, dobutamine was infused at a rate of 4 micro g [centered dot] kg-1 [centered dot] min-1. Core temperature, skin temperature, tissue temperature, and laser-Doppler perfusion index were measured. Leg heat content was calculated by morphometric data and observed temperatures. The decrease in leg heat content was larger in the control group than in the experimental group 30 min after anesthetic induction (P < 0.05). In contrast, the core temperature decreased further in the dobutamine group than in the control group 40 min after induction (P < 0.05). Dobutamine induced further hypothermia, presumably by facilitating heat transfer and by increasing cutaneous heat loss. Hypothermia will be increased when using dobutamine for anesthesia.

Anti-inflammatory effects of a Houttuynia cordata supercritical extract

Anti-inflammatory effects of Houttuynia cordata supercritical extract (HSE) were investigated in a carrageenan-air pouch model. HSE (200 mg/kg, oral) suppressed exudation and albumin leakage, as well as inflammatory cell infiltration. Dexamethasone (2 mg/kg, i.p.) only decreased exudation and cell infiltration, while indomethacin (2 mg/kg, i.p.) reduced exudate volume and albumin content. HSE lowered tumor-necrosis factor (TNF)-α and nitric oxide (NO), as well as prostaglandin E2 (PGE2). Dexamethasone only reduced TNF-α and NO, while indomethacin decreased TNF-α and PGE2. The suppressive activity of HSE on NO and PGE2 production was confirmed in RAW 264.7. These results demonstrate that HSE exerts anti-inflammatory effects by inhibiting both TNF-α-NO and cyclooxygenase II-PGE2 pathways.
