BASE COMPOSITION OF DEOXYRIBONUCLEIC ACID OF MARINE AND NONMARINE VIBRIOS DEDUCED FROM BUOYANT-DENSITY MEASUREMENTS IN CESIUM CHLORIDE

temperature for 7 days before use. Six to eight replicates were made from each of two sets of nine master plates with floc and velveteen, and were incubated at 20 C for 7 days. Results were assessed both qualitatively and quantitatively. Replicates made with floc showed no colony spreading and merging due to excess moisture. However, small colonies were progressively squashed and merged with those close to them. Larger colonies were distorted in shape and sometimes replicated as groups of small, discrete colonies. Small colonies were lost. Cell material was spattered, producing colonies absent from the master plates. Fibers were shed onto the agar surfaces. Shape, flexibility, and arrangement of the fibers appeared to account for the effects observed. Inocula were often found on fiber shafts instead of tips. When deposited, this material could smear, giving a squashed-colony effect. Colonies close together, when smeared, could then merge. Groups of fibers, behaving similarly, could account for the distortion and polka-dot reproduction of larger colonies. Flexed fibers carrying inocula, on springing back to their original shapes, could spray cells onto replicate surfaces. Colonies might not be replicated for several reasons. Fibers could fail to contact the colonies. Examination of master-plate surfaces after impression showed fiber marks far apart and irregularly spaced. In contrast, pile marks were very close together and regularly spaced. Cell material might be picked up on shaft or tip of a fiber and not be deposited from either region because of a random lesser or greater flexion of the fiber. Shed fibers could result in the loss or misplacement of colonies. In its present form, floe is decidedly inferior to velveteen. An improved material requires fibeis which stand erect, are more resistant to deformation, and are more closely and regularly spaced.
Ultrasound simulators: experience with the SonoTrainer and comparative review of other training systems

Ultrasound has become indispensable in prenatal diagnosis. Ultrasound training, however, still lacks proper quality assessment and control. Moreover, most fetal anomalies which must be diagnosed during pregnancy are extremely rare. Ultrasound simulators could provide an opportunity to overcome this dilemma. This review summarizes the potential benefits of simulator‐based ultrasound training, briefly describes the properties of a variety of ultrasound simulators that have been developed for various applications including prenatal diagnosis, and presents the SonoTrainer sonography simulation system which makes it possible to run a real‐time simulation of a complete prenatal ultrasound examination. We evaluated the system for the training of first‐ and second‐trimester screening for both normal and pathological findings and found that physicians who received theoretical training and were additionally trained with the simulator (T + S) significantly improved their skills in measurements of nuchal translucency thickness (NT) and crown–rump length (CRL) as compared with colleagues who only underwent theoretical instruction (T) [mean ± SD NT deviation: 0.31 ± 0.1 mm (T + S) vs. 0.62 ± 0.2 mm (T), P < 0.05; mean ± SD CRL deviation: 1.48 ± 2.0 mm (T + S) vs. 3.27 ± 2.5 (T), P < 0.05]. Simulator‐based training enabled physicians to diagnose rare fetal anomalies in the second trimester with a sensitivity of 86% and a specificity of 100%. In a study in which second‐trimester scans including fetal anomalies were presented to physicians, 96% of the participants subjectively estimated their training effect as being good. We therefore conclude that simulator‐based training would provide an ideal educational tool to test, improve and monitor a physician's or technician's ultrasound skills in detecting fetal anomalies.

Receptive Fields in the Cat Retina: A New Type

A new type of receptive field of cat retinal ganglion cells is described and termed the "suppressed-by-contrast" type. The firing rate of these cells is suppressed by a variety of visual stimuli. However, it has not been possible to find a stimulus that increases the firing rate above the maintained level.
Observation of Coexisting Mesoscale Lake-Effect Vortices over the Western Great Lakes

Mesoscale vortices are one of several types of wintertime lake-effect structures that are observed over the Great Lakes region as cold arctic air is rapidly modified from below by warm lake waters. These vortices are thought to occur less frequently than other lake-effect structures, such as wind-parallel snowbands (e.g., Kristovich 1993), which are responsible for greater than half of the yearly snowfall downwind of the western Great Lakes (Kelly 1986), and more intense shore-parallel snowbands, which can produce localized heavy snowfalls (e.g., Braham 1983). Through the examination of visible satellite imagery, Forbes and Merritt (1984) found 14 cases of mesoscale vortex formation over the Great Lakes in the years 1978–82. This suggests that, on average, a mesoscale vortex will occur within the Great Lakes region less than four times a winter. During an early winter lakeeffect event on 13 November 1995, intense land-breeze circulations and four mesoscale vortices (.50-km diameter) developed over Lakes Superior, Huron, and Michigan simultaneously (Fig. 1). This unique observation of coexisting lake-effect vortices over the western Great Lakes has not previously been reported in the literature and suggests that atmospheric conditions favorable for vortex development were widespread throughout the region. Previous cases have typically observed a single vortex, suggesting that favorable meteorological conditions were localized. The author is aware of only two other reported observations of simultaneous mesoscale vortices within the Great Lakes region (Schoenberger 1986; Pitts et al. 1977). However, the lake-effect vortices that Schoenberger (1986) and
Anti-Tumorigenic Effects of Capsaicin in Colon Cancer

Colon cancer is one of most common malignancies in the world. Capsaicin is a major component of chili peppers and has been shown to possess anti-cancer activity against various types of cancers. There is currently a limited number of preclinical studies that test the anti-cancer effects of capsaicin in colon cancer. The first objective of the present study is to investigate whether capsaicin influences tumor formation using a colon cancer mouse model. The second objective is to elucidate the anti-cancer mechanism of capsaicin using an in vitro cell culture system. For the in vivo study, we treated ApcMin+/ mice having truncated deletion of APC (adenomatous polyposis coli) with capsaicin. For the in vitro study, we exposed human colorectal cancer cell lines to different concentrations of capsaicin and performed western blot analysis. Oral gavage of capsaicin at a dose of 20 mg/ kg body weight for 4 weeks tended to decrease the number of polyps (43.5 ± 14.6 vs 27.8 ± 8.8, p = 0.114) and tumor load (78.6 ± 20.9 vs 47.4 ± 21.3, p = 0.083) in the intestine of ApcMin+/ mice. In vitro studies showed that, in human colon cancer cells, capsaicin induced phosphorylation of cyclin D1 at threonine 286 (T286) and decreased cyclin D1 expression in a doseand time-dependent manner. In addition, capsaicin treatment increased intracellular ubiquitination of proteins in a dose-dependent manner and decreased the caspase-like activity of 20S proteasome significantly (p = 0.026). This study identifies capsaicin as a potential anti-cancer agent that targets cyclin D1 degradation and proteasome activity in colon cancer.
Predictability of saccadic behaviors is modified by transcranial magnetic stimulation over human posterior parietal cortex

Predictability in the visual environment provides a powerful cue for efficient processing of scenes and objects. Recently, studies have suggested that the directionality and magnitude of saccade curvature can be informative as to how the visual system processes predictive information. The present study investigated the role of the right posterior parietal cortex (rPPC) in shaping saccade curvatures in the context of predictive and non‐predictive visual cues. We used an orienting paradigm that incorporated manipulation of target location predictability and delivered transcranial magnetic stimulation (TMS) over rPPC. Participants were presented with either an informative or uninformative cue to upcoming target locations. Our results showed that rPPC TMS generally increased saccade latency and saccade error rates. Intriguingly, rPPC TMS increased curvatures away from the distractor only when the target location was unpredictable and decreased saccadic errors towards the distractor. These effects on curvature and accuracy were not present when the target location was predictable. These results dissociate the strong contingency between saccade latency and saccade curvature and also indicate that rPPC plays an important role in allocating and suppressing attention to distractors when the target demands visual disambiguation. Furthermore, the present study suggests that, like the frontal eye fields, rPPC is critically involved in determining saccade curvature and the generation of saccadic behaviors under conditions of differing target predictability.

Modeling of STI-induced stress phenomena in CMOS 90nm Flash technology

A non negligible layout sensitivity of MOSFETS electrical behavior has been recently observed in advanced CMOS technologies. Some efforts have been attempted to encapsulate this phenomenon in Spice-like simulation oriented models. In the present work, we suggest improvements to previously proposed approaches, after a critical discussion about them. An extensive characterization of CMOS 90 nm Flash memory technology is the support of our issues. Finally, simulation of prototype circuits shed some light on the impact of STI stress in IC design.
Cardiovascular Responses to Postural Changes: Differences with Age for Women and Men

The cardiovascular responses to postural change, and how they are affected by aging, are inadequately described in women. Therefore, the authors examined the influence of age and sex on the responses of blood pressure, cardiac output, heart rate, and other variables to change in posture. Measurements were made after 10 minutes each in the supine, seated, and standing positions in 22 men and 25 women who ranged in age from 21 to 59 years. Several variables differed, both by sex and by age, when subjects were supine. On rising, subjects' diastolic and mean arterial pressures, heart rate, total peripheral resistance (TPR), and thoracic impedance increased; cardiac output, stroke volume, and mean stroke ejection rate decreased; and changes in all variables, except heart rate, were greater from supine to sitting than sitting to standing. The increase in heart rate was greater in the younger subjects, and increases in TPR and thoracic impedance were greater in the older subjects. Stroke volume decreased less, and TPR and thoracic impedance increased more, in the women than in the men. The increase in TPR was particularly pronounced in the older women. These studies show that the cardiovascular responses to standing differ, in some respects, between the sexes and with age. The authors suggest that the sex differences are, in part, related to greater decrease of thoracic blood volume with standing in women than in men, and that the age differences result, in part, from decreased responsiveness of the high‐pressure baroreceptor system.
An outbreak of Salmonella saint-paul infection associated with beansprouts

SUMMARY In March 1988, there was an outbreak of infection by a strain of Salmonella saint-paul with a distinctive antigenic marker. A total of 143 reports were received between 1 March and 7 June. Preliminary investigations suggested that raw beansprouts were a possible source of infection and a case-control study confirmed the association. S. saint-paul of the epidemic type was isolated from samples of beansprouts on retail sale in different cities in the United Kingdom and from mung bean seeds on the premises of the producer who was most strongly associated with cases. In addition, Salmonella virchow PT34 was isolated from samples of raw beansprouts and was subsequently associated with seven cases of infection. Four other serotypes of salmonella were also isolated from beansprouts. On 8 April the public were advised to boil beansprouts for 15 seconds before consumption, and the premises of the one producer associated with many cases were closed. As a result of these actions there was a significant decrease in the number of infections with S. saint-paul.
Betel nut chewing: Recognizing an important but unfamiliar cause of oral cancers.

s primary healthcare providers in a growing global environment, it is imperative that nurse practitioners (NPs) stay up-to-date with global health concerns and seek learning opportunities that will further their expertise in clinical practice and enhance culturally competent care. NPs are educated to perform exams of the mouth and buccal mucosa to assess for precancerous and cancerous lesions in patients with related history, such as tobacco use. The following case study is reported to educate and raise awareness about betel nut chewing, a growing but lesser-known cause of oral squamous cell carcinoma (OSCC) and oral lesions.
Cross-sectional population based study ascertaining the characteristics of US rural adults with mental health concerns who perceived a stigma regarding mental health issues

Introduction: Mental health is an important component of overall health. Mental illness is a leading cause of morbidity and mortality in the US and is associated with chronic diseases such as heart disease, diabetes, and arthritis. In the US, most people with mental health issues or disorders remain untreated. Epidemiological studies have identified rural residents as being at greater risk for health disparities; as a result, rural residents are a vulnerable population in terms of mental health and mental health care. Research has demonstrated that perceived stigma can be a significant barrier to rural residents seeking mental health care. This study examined the research question: What are the characteristics of US rural adults with mental health concerns who perceived stigma? Methods: 2007 Behavioral Risk Factor Surveillance System (BRFSS) data were analyzed using bivariate and multivariate techniques to answer the research question. 2007 BRFSS data were used because in that year non-institutionalized US adults in 37 states and territories were queried about their attitudes toward mental illness. BRFSS is a random digit telephone survey that uses a complex multi-stage sampling approach and subsequently a weighting factor is calculated for application to the data in order to ensure that they are representative of the US population based on the most recent census data. Only weighted data were analyzed. Results: Logistic regression analysis revealed that rural adults reporting mental health concerns who perceived stigma regarding mental health were more likely to be unemployed seeking work or not working and not seeking work, military veterans, or to have deferred medical care because of cost. They were also more likely to not have a health care provider and to rarely or never feel supported emotionally. Conclusions: Support systems may render people with mental health issues less vulnerable to perceiving stigma, thus assisting with removing stigma as a barrier to care. Pharmacist may play a role as support in communities, especially where access to health care providers may be limited.
Vaccinia and ectromelia in the mouse.

TiHE virus of infectious ectromelia can be inactivated with ultra-violet radiation; such inactive virus can evoke immunity, and can suppress the lethal effects of living virus inoculated intraperitoneally into mice at the same time. Another example of the "interference phenomenon" is thus in evidence (Andrewes and Elford, 1947). Burnet and Boake's (1946) finding of a close relationship between the viruses of vaccinia and ectromelia prompted us to investigate the properties of irradiated vaccinia virus and the abilitv of vaccinia to interfere with the effects of ectromeLia in mice.
High-Power Pulse Semiconductor Laser-Thyristor Emitting at 900-nm Wavelength

High-power pulse semiconductor lasers based on epitaxially integrated thyristor heterostructures were developed. The possibility of generating high-power laser light pulses with duration on the order of 100 ns at control signal amplitude on the order of 40-100 mA at extremely low turn-on thyristor voltage of 10 V was demonstrated. The values reached for the peak pulse optical power and peak pulse current were 28 W and 37 A, respectively.
Common Phase Estimation in Coherent OFDM System Using Image Processing Technique

In a coherent orthogonal frequency division multiplexing system, the possible rotation of the rectangular signal constellation, due to common phase error, is shown to be effectively compensated by applying an skew compensation technique adopted in image processing area. We further propose an improved technique to further reduce the complexity of the algorithm and investigate the effect of the number of required test phases, via numerical simulations. The proposed improved algorithm is also compared with the conventional blind phase searching algorithm. It is shown that by employing only two bits of overhead, it can achieve a comparable performance to that of the traditional pilot aided method.
Linearity-optimized power tracking GaN HEMT Doherty amplifier using derivative superposition technique for repeater systems

This paper presents the linearity-optimized power tracking Gallium Nitride (GaN) high electron mobility transistor (HEMT) Doherty power amplifier (DPA) for wide-band code division multiple access (WCDMA) repeater systems. Also, we analyze effects of the drain bias of the carrier amplifier on the linearity and efficiency of the DPA. To improve linearity of the DPA without extra linearization techniques, the derivative superposition technique (DST) is employed by using higher drain bias of carrier amplifier than that of peaking amplifier and the optimization of the gate bias of peaking amplifier. The optimum drain and gate biases are adaptively controlled by the power tracking bias supply circuit. For experimental validation, the DPA is designed and implemented with 25-W peak envelope power (PEP) GaN HEMT and tested with a 1-carrier WCDMA signal of 2.14 GHz. At an adjacent channel leakage ratio (ACLR) of −45 dBc, a Pout of 39.4 dBm (7.6-dB back-off power from Psat) and a power-added efficiency (PAE) of 31.8% is achieved for the power tracking DPA. For the conventional DPA, a Pout of 32.7 dBm with a PAE of 21.4% is achieved at an ACLR of −45 dBc.

Is eccentric exercise-induced torque decrease contraction type dependent?

PURPOSE This study was designed to determine whether torque decrease following an acute eccentric exercise is contraction type dependent. METHODS Ten active males performed an exercise session consisting of five sets of ten maximal eccentric muscle actions of the elbow flexors. Before and immediately after the exercise, maximal voluntary eccentric (-60 degrees.s-1; Ecc60), isometric (0 degrees.s-1; Iso) and concentric (60 degrees.s-1; Con60 and 240 degrees.s-1; Con240) torque were measured. In order to distinguish central from peripheral factors involved in torque decrement, activation level (twitch interpolation technique), myoelectrical activity (RMS) of biceps brachii, as well as electrically evoked M-wave and peak twitch torque (Pt) were recorded. RESULTS The eccentric exercise induced a significant torque reduction (P < 0.01), whatever the muscular contraction type [mean (SD): -22.3 (8.1)% for Ecc60; -20.8 (11.2)% for Iso; -18.5 (6.1)% for Con60 and -12.5 (8.9)% for Con240]. Relative torque decrement was however significantly less for Con240 compared with Ecc60, Iso, and Con60 (P < 0.05). Torque decreases were associated with a reduction of both M-wave amplitude (P < 0.01) and Pt (P < 0.001), probably related to an impairment of the excitation-contraction coupling. Concurrently, activation level was reduced (P < 0.01), therefore indicating the occurrence of central fatigue, as also confirmed by RMS decreases for all the conditions (P < 0.05), except Con240. DISCUSSION An acute eccentric exercise induced a significant voluntary maximal torque reduction during eccentric, isometric, and concentric muscle actions ascribed to both peripheral and central failure of force production capacity. It can be concluded that eccentric exercise-induced torque decrease is not contraction type dependent.
