In addition, a vigorous search of the mesorectum was performed to identify as many lymph nodes as possible and all identified lymph nodes were submitted entirely for microscopic evaluation. For the evaluation of tumor response, Dworak grading system (12)

was used by two gastrointestinal pathologists at Istanbul Medical Faculty, Department of Gastrointestinal Pathology. Pathologic response was evaluated using Total Regression Inhibitors,research,lifescience,medical Score (TRG), where TRG IV indicates no viable cancer cells and TRG 0 indicates no downgrading. Acellular pools of residual mucin in specimens were considered to represent completely eradicated tumor. Follow-up Patients were followed up routinely at 3-month intervals for the first 2 years after the operation and at 6-month intervals during next years. A local recurrence was defined as a radiologically demonstrated Inhibitors,research,lifescience,medical or a biopsy proven tumor within pelvis or perineum. Disease-free survival (DFS) and overall survival (OSS) were defined as the time from initiation of chemotherapy to the first evidence of relapse or death. Inhibitors,research,lifescience,medical Statistical analysis Statistical analysis was performed using SPSS software version 16.0 (SPSS, Chicago, IL). Kaplan-Meier method was used to analyze survival and the differences in survival probabilities were assessed using log-rank test. Mann-Whitney U, chi-square and Fisher’s exact tests were used, where applicable.

Statistical significance was set at 0.05. learn more Results Patient characteristics Between January 2002 and December 2007, 170 eligible patients were enrolled in the trial. Baseline characteristic and clinical outcomes of the patients are shown in Table 1. Groups were similar with regard to patient Inhibitors,research,lifescience,medical characteristics. Seventeen patients (9 patients from group A and 8 patients from group B) were withdrawn from the study due to following reasons: intestinal obstruction (2 patients), M1 identified at surgery (5 pts), patient preferred local excision (2 pts), frozen pelvis found at operation (5 pts), progression during

treatment (3 pts). Table 1 Patient characteristics Inhibitors,research,lifescience,medical and clinical outcomes Clinical outcomes Lateral and distal surgical margin positivity was present in 11 and 3 patients, respectively. The two groups did not differ with regard to lateral surgical margin positivity and pathological tumor regression rate. Local recurrence occurred in 9 (11.8%) and 8 (10, 3%) patients in Group A and Group B, respectively. Local recurrence rate was significantly higher Metalloexopeptidase among patients with surgical margin positivity (either lateral or distal) compared to patients with negative margins (28.5% vs. 9.3%, P=0.02). Group A and Group B had similar 5-year overall survival (76.5% vs. 74.2%, P=0.60) (Figure 1A) and disease free survival rates (73.2% vs. 70.5%, P=0.80) (Figure 1B). Overall survival was better in patients with negative surgical margins (78.8% vs. 53.0%, P=0.04) (Figure 1C). In addition, local recurrence was associated with worse survival (37.7% vs. 80.3%, P<0.

The type of PS was diagnosed using the 2D echocardiography and t

The type of PS was diagnosed using the 2D echocardiography and the severity was measured using the Doppler echocardiographic measurement assessed by modified Bernoulli equation. Echocardiography datas were collected from ramdomized results, using our center modality, Philips IE 33 (Philips Andover, Andover, MA, USA), GE vivid E9 (GE Healthcare, Fairfield, Inhibitors,research,lifescience,medical CT, USA), The Siemens

Acuson sequoia 512 (Siemens Germany, North Rhine-Westphalia, Germany). Parasternal short axis view is mainly used for evaluation of PS, and additional view was performed, when it was nessacery. The peak-to-peak pressure gradient difference between the RV and the PA was measured, as well as the mean transpulmonic pressure gradient. When the gradient on echocardiography was greater than 40 mmHg, or the estimated right ventricular pressure was greater than 50 mmHg, patients who have exertional dyspnea, angina, syncope, or presyncope and RV-PA peak-to-peak gradient greater than 30 mmHg at catheterization,

BPV was Inhibitors,research,lifescience,medical indicated.9),10) During the transcatheter procedure, the pre-procedural measurement between the RV and PA was measured and the post-procedural Inhibitors,research,lifescience,medical measurement was also measured, to decide the success of the procedure. We considered the procedure Ku-0059436 in vitro successful when the pressure gradient was less than 20 mmHg. Follow-up echocardiography was performed within 24 hours of the procedure, 1 week, 3 months, 6 months, and yearly thereafter. Parametric data were entered into a Microsoft Excel 2007 spreadsheet (Microsoft, Redmond, WA, USA). Results

are presented as mean ± standard deviation or numbers and percentages Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical and analyzed using MedCalc ver (MedCalc Software, Ostend, Belgium). Results Subjects The mean age of the patients were 38.35 months (± 48.55 months) and they ranged from 1 month to 192 months (16 years old), the median age was 17 months. Of the 112 total patients, there were 46 male patients (41.07%) almost and 66 female patients (58.92%). Patients with concomitant simple observable heart diseases consisted of 32 patients. They were 29 atrial septal defect patients (25.9%), 2 ventricluar septal defect patients (1.8%), 3 patent ductus arteriosus patients (2.7%) and 3 patent foramen ovale patients (2.7%). The mean follow-up duration of the patient was 30.64 months (± 26.84 months) ranging from 3 months to 108 months (median, 24 months) (Table 1). Table 1 The clinical data of patients with pulmonary valve stenosis Adverse events There were no noted major complications. Two cases (1.79%) of minor complications were detected, both of which were spiking fever, but both subsided after a day (Table 1). Echocardiographic data The type of diagnosed PS were 85 valvular PS (75.

In addition to focusing on further advancing the analytical metho

In addition to focusing on further advancing the analytical methodologies and manufacturing capabilities (as discussed below) for these components, Calando made substantial effort in the early days to identify an initial cancer

gene target suitable for eventual clinical application and to optimize an siRNA to downregulate that target. Calando selected the M2 subunit of ribonucleotide reductase (RRM2), an established anticancer target which catalyzes a STA-4783 rate-limiting step in the production of 2′-deoxyribonucleoside 5′-triphosphates which are necessary for DNA replication. Just as TfR overexpression Inhibitors,research,lifescience,medical across a variety of cancer types opened the possibility of RONDEL-based nanoparticles to achieve uptake in many different classes of tumors, the demonstrated sensitivity of many cell types to RRM2 inhibition maintained the Inhibitors,research,lifescience,medical potential generality of anti-RRM2 siRNA-containing nanoparticles to treat multiple types of cancers. A combination of in silico and in vitro screening of many siRNA candidates led to identification of a lead sequence (named “C05C”; also referred to as “siRRM2B + 5”) which was shown to be a potent downregulator of RRM2 in cancer cells of various types and species and induced a concomitant antiproliferative Inhibitors,research,lifescience,medical effect in those cells

[24]. Having defined the four components of Calando’s putative lead candidate formulation (CAL101, AD-PEG5000,

AD-PEG5000-Tf, and C05C), named “CALAA-01,” campaigns to scale up the manufacturing of each component were made while simultaneously expanding and improving Inhibitors,research,lifescience,medical the analytical methods employed to characterize each of them. The manufacturers of the lots of components used for IND-enabling toxicology studies and initial clinical material are listed in Table 6. Improvements Inhibitors,research,lifescience,medical in scale of up to three orders of magnitude were achieved for these molecules, and, as is customary for such projects, several challenges were identified and overcome during development. For example, in the case of CAL101, a previously unidentified impurity created in the initial β-CD functionalization step was observed that could be carried only through subsequent steps; methodologies for quantifying and removing this species were developed and employed. Ultimately, sufficient quantities of all components were obtained that satisfied all acceptance criteria and were employed for subsequent testing. Table 6 Manufacturers of primary toxicology and initial clinical lots of CALAA-01 components. Preclinical safety and efficacy testing of CALAA-01 were performed across a number of species and tumor types, respectively. A dose-range-finding study in non human primates [25] provided an early glimpse of the safety profile at each of three different dose levels (3, 9, and 27mg/kg with respect to C05C).

This perspective begins to explain why regulators require evidenc

This perspective begins to explain why regulators require evidence of positive drug effects on either clinician-rated impression of change scales or ADL scales. Intuitively, it seems reasonable to suppose that enhancements in cognition are likely to be accompanied by improvements in day-to-day functioning. However, data in support of this proposition are sparse and the concern remains that Inhibitors,research,lifescience,medical DAPT secretase datasheet cognitive changes reported using scales such as the ADAS-COG may not be accompanied by clinically relevant, functional improvements. Clear evidence that cognitive enhancement reliably accompanied functional improvement might, allow us to reduce the role the clinician’s rating and/or

ADL scale assessments. Evidence from one computerized system is available

in a large trial with data available for 744 AD patients. Here the Instrumental Activities of Daily living scale was administered predosing, together with the computerized cognitive tests. There were highly significant, correlations between the Inhibitors,research,lifescience,medical ADL scale and the three major factor scores from the computerized system (r=0.43 for power of attention, r=0.39 for speed of memory, and r=0.48 for quality of memory; all Inhibitors,research,lifescience,medical P<0.0001). These correlations, while not large in magnitude, clearly identify a direct relationship between these cognitive assessments and how well the patients were judged to cope with everyday activities. In previous work with the same system, correlations of up to 0.79 were seen on individual task measures and the Stockton Geriatric Rating Inhibitors,research,lifescience,medical Scale, a scale completed by ward staff concerning the abilities of institutionalized

geriatric patients to conduct. ADL.5 As more data of this kind accumulate so will the acceptance grow that changes in tests of cognitive function have clinical significance for everyday behavior. Inhibitors,research,lifescience,medical Overall conclusions and recommendations The traditional dementias, AD and VaD, must be acknowledged to be far more than simply disorders of memory. Trials that evaluate the effectiveness of of potential therapies need additionally to include sensitive assessments of the other aspects of dysfunction, such as attention. DLB accounts for between 15% and 25% of all dementias, and does not have memory deficits as a core feature of the disease. Trials to assess the efficacy of novel treatments for DLB should therefore use cognitive test systems that address the major impairments of disorder, and attentional assessments are particularly relevant here. Cognitive tests should only be administered under the direct supervision of individuals suitably trained in psychology, and proof of such supervision should be a regulatory requirement. Automated cognitive tests are available and can identify an earlier onset of improvements in dementia in smaller sample sizes than the ADAS.

Boldly put, “facts are ventriloquists’ dummies. Sitting on a wise man’s knee they may be made to utter words of wisdom; elsewhere, they say nothing, or talk nonsense, or indulge in sheer diabolism” (quote attributed to Aldous Huxley). Science advances by postulating concepts and making assumptions, and then investigating to determine whether these concepts and assumptions are successful in explaining and predicting phenomena observed in nature or in the laboratory. As successful explanations grow, it becomes more and more plausible that the assumed concepts and ideas are basically correct and become scientific “facts”. In science, Inhibitors,research,lifescience,medical “fact” can only mean confirmed to such a degree

that it would be perverse to withhold Inhibitors,research,lifescience,medical assent. I suppose it is possible that the theory of gravitation is false

and apples might stop falling to the ground and start rising, but the possibility does not merit any serious consideration. Steinberg further states that “it is important to distinguish between conclusions drawn from controlled experiments, and a theory, a speculation, or an assumption”. Consequently he charges that many of the premises of the evolution theory are unproved speculation: “evolution is only a theory; therefore, one can accept that which is fact and experimentally proven and Inhibitors,research,lifescience,medical reject that which is an unsubstantiated hypothesis, or replace it by an alternative explanation”. It is important to emphasize here that facts and theories are not rungs in a hierarchy of increasing certainty. Facts are the world’s data, while theories are structures that explain and interpret data. Facts do not go away when scientists debate rival theories to explain them. Einstein’s theory of gravitation replaces Newton’s, but apples did not suspend themselves in mid air, pending Inhibitors,research,lifescience,medical the outcome. Humans evolved from apelike ancestors whether they did so by Darwin’s proposed mechanism or by some other yet to be discovered.3 Steinberg introduces

a list of creationist Inhibitors,research,lifescience,medical claims but without being able to bring one single reference from the professional peer-reviewed literature, because creationist standards of scholarship are too low for publication in professional, reputable journals. For example, he challenges the fossil evidence, including the claim of a “JQ1 molecular weight missing link”, namely the lack of transitional fossils Cediranib (AZD2171) from lower to higher species. Even a cursory analysis of the professional literature would prove that these claims are incorrect. Based upon the consensus of numerous phylogenetic analyses, the chimpanzee is the closest living relative of humans. Thus, we expect that organisms lived in the past which were intermediate in morphology between humans and chimpanzees. Indeed, over the past century, many spectacular paleontological finds have identified such transitional hominid fossils. Or take the Ambulocetus (the “walking whale”), the transitional fossil that shows how whales evolved from landliving mammals. As S. J.

Moreover, there was no significant difference between the serum levels of TG, total cholesterol, LDL-C, or HDL-C of the diabetic control and the SBO-treated (200 or 600 mg/kg/day) groups (table 1). There was also no significant difference between

the effects of the two oils (PSO and SBO) on such variables. Table 1 Serum lipid profile Inhibitors,research,lifescience,medical and levels of the indices of oxidative stress (mean±SD, n=8) of the control rats and diabetic rats treated with vehicle, pomegranate seed oil at 200 (PSO1) or 600 mg/kg/day (PSO2), or SBO at 200 mg/kg/day (SBO1) or 600 mg/kg/day … Serum concentrations of MDA (P=0.04) and GPX (P=0.001) of the diabetic control rats were, respectively, higher and lower than those of the normal control rats (table 1). Neither PSO nor SBO affected serum MDA significantly compared to that of the diabetic control group.  Neither Inhibitors,research,lifescience,medical PSO nor SBO (200 mg/kg/day) affected serum GPX significantly compared to that of the diabetic control group. However, the serum levels of the GPX of the group treated with PSO at 600 mg/kg/day was significantly higher than those of the diabetic control group and the diabetic group treated with SBO at 600 mg/kg/day (P=0.005) (table 1). Discussion The findings of the present study

Inhibitors,research,lifescience,medical indicate that a simultaneous administration of Nicotinamide and Streptozocin resulted in type 2 diabetes mellitus, characterized by increased blood glucose, lipid profile, and oxidative stress as well Inhibitors,research,lifescience,medical as with decreased serum insulin. They also Akt inhibitor showed that PSO increased serum

insulin and decreased oxidative stress, without affecting serum lipid profile. The present model of diabetes was associated with decreased serum insulin and increased blood glucose. Such findings are similar to those of previous studies using the same model of diabetes15 or other models of diabetes.16 The model was also associated with increased oxidative stress, which is similar Inhibitors,research,lifescience,medical to that of previous studies.4,5 The findings of the present study indicate that PSO did not decrease blood glucose. To the best of our knowledge, this is the first report to evaluate the effect of PSO in an animal model of type 2 diabetes, whereas previous investigations focused mainly on hyperlipidemic6,7,17or normal animals8 or hyperlipidemic subjects.11 The lack of PSO effect on blood glucose Oxygenase is similar to that of previous reports.6,7 Such a finding might be due to the presence of insulin resistance, since fat administration is associated with insulin resistance. The study also showed that PSO increased the serum levels of insulin, but such an increase did not translate into the reduction of blood glucose level. Although the insulin secretion capacity of PSO has not been evaluated previously, improvement in insulin resistance was reported to be significant in hyperlipidemic animals.6,7 The mechanism of a PSO-induced increase in serum insulin is not clear.

However, the absence of saccade occurrences during


However, the absence of saccade occurrences during

MOT might point toward the employment of saccade inhibition processes (e.g., Culham et al. 1998). The significance of the FEF for the inhibition of exogenous, visually guided saccades has been a matter of debate. While there have been studies suggesting the FEF to be crucially involved in oculomotor-related inhibitory processes Inhibitors,research,lifescience,medical (Connolly et al. 2000; Kimmig et al. 2001; Pierrot-Deseilligny et al. 2004), it is noteworthy that the inhibition of exogenous saccades is usually measured by means of the “antisaccade paradigm.” This paradigm requires the performance of saccades toward the direction opposite to the locus of appearance of a 3-Methyladenine in vitro visual object. Thus, result interpretation regarding the neural substrates of saccade inhibition based on this paradigm, where saccade suppression (toward the target), computation of the target’s mirror position, and saccade execution (toward said mirror position) are confounded, is Inhibitors,research,lifescience,medical problematic. In line with this

reasoning, there have been clinical findings painting a less clear picture of FEF involvement in inhibitory oculomotor control (Gaymard et al. 1999). A paradigm allowing for a Inhibitors,research,lifescience,medical more valid comparison with assumed eye movement inhibition in our MOT task would be saccade suppression during fixation with concurrently appearing peripheral visual stimuli. Neggers et al. (2012) tested this paradigm, the contrast of [Fixation with Peripheral Stimuli > Fixation without Peripheral Stimuli] revealing the following activation maxima (MNI, x/y/z): −38/−6/52, −52/0/38, 44/−2/52. As Inhibitors,research,lifescience,medical these activations are at the most tangentially overlapping

with the activations found in the DLFC in our MC (maxima: −15/−10/67, 21/−10/61), we are confident that our allegedly found PMd activation did not originate from oculomotor suppression during visual fixation. Spatial attention and the DLFC Aside from oculomotor control, prior fMRI studies on MOT attributed activation in the DLFC to spatial attention during visual search (Culham et al. 1998, 2001; Jovicich et al. 2001; Howe et Inhibitors,research,lifescience,medical al. 2009). Indeed, brain activation related to spatial attention has been previously ascribed to the FEF (Corbetta 1998; Zacks et al. 2001), suggesting a strong link between the government of spatial attention and oculomotor control (“premotor theory of attention,” Rizzolatti et al. 1987). Other studies that found PD184352 (CI-1040) activation in the DLFC during the performance of spatial attention tasks have implicated the PMd as the region of origin. Boussaoud (2001), for instance, suggested that there are two subdivisions of the PMd, a rostral and a caudal part, that are rather distinct in regard to their functionality. While the caudal part appeared to be primarily involved in movement planning, the rostral part seemed to be mainly associated with the maintenance of spatial stimulus representations (Simon et al. 2002).

They found that all three groups had a reduction in depressive symptoms, with exercise showing a slightly greater benefit. Two studies found antidepressant effects of progressive resistance training in older adults with depression. Singh and colleagues studied the effects of progressive resistance training

(PRT) on depressed adults 60 years and older Inhibitors,research,lifescience,medical with a mean (SD) age of 71.3 (1.2).55 Over 10 weeks compared with an attention-control group, PRT was associated with an improvement in the measures of depressive symptoms, quality of life, social functioning, and strength. In a follow-up study, Singh and colleagues found that higher-intensity PRT was more effective than low-intensity PRT on depression in older

adults.56 These studies support the argument that exercise has antidepressant effects in older adults, yet the mechanism of action Inhibitors,research,lifescience,medical remains unclear. The studies are careful to note the potential for the antidepressant effects Inhibitors,research,lifescience,medical of expectation and attention in research participation as well as for socialization when engaging in group exercises.51 Further, investigators have also suggested the effects of increased self-efficacy, a sense of mastery, positive thoughts, distraction from negative thoughts, and enhanced self-concept.59 However, GDC-0068 research buy biological mechanisms related to overall brain health are also likely related to the mood elevating properties of exercise. These mechanisms, described earlier, include enhanced gray matter volume in prefrontal cortex and hippocampal brain areas,

elevated functioning of brain circuits involved in mood and emotional function such as Inhibitors,research,lifescience,medical subregions of Inhibitors,research,lifescience,medical the frontal cortex and medial temporal lobe, and improvements in functional connectivity of the default-mode network. In addition, it is also likely that exercise is having a pleiotropic effect on molecular systems related to the hypothalamic-pituitary-adrenocortical axis, dopaminergic, noradrenergic, serotonergic neurotransmission, immune click here function, and BDNF (Figure 1). 60,61 However, these biological mechanisms of exercise have not yet been carefully studied in older adults with depression. The role that changes in morphology and function could have on mitigating depressive symptoms remains speculative at this time. Figure 1. A schematic representation of the general path by which cognitive function and mood are improved by physical activity, it could be hypothesized that improvements in cognitive function mediate the improvements in mood or that improvements in mood mediate … Conclusions and future directions In this review we have briefly summarized the expansive and ever-growing literature on the effects of physical activity on brain health and plasticity.

Sleep basics Electrophysiological recordings of human brain revea

Sleep basics Electrophysiological recordings of human brain reveal three distinct state of existence: wakefulness, rapid eye movement (REM) sleep, and non-REM (NREM) sleep. The distinction between sleep and wakefulness is attributed to the synchronization and desynchronization of thalamocortical circuits.6,7 Wake-like or “desynchronized” (low-amplitude and high-frequency) electroencephalographic

(EEG) activity with clusters of REM and very low levels of muscle tone characterize REM sleep. NREM sleep includes all sleep except REM sleep, and is by convention divided into four stages corresponding to increased depth of sleep as indicated by the progressive dominance of “synchronized” Inhibitors,research,lifescience,medical EEG activity (also known as low-voltage high-amplitude delta or slow-wave activity); in this respect, sleep stages 3 and 4 are collectively labelled as delta sleep or slow-wave sleep (SWS). Inhibitors,research,lifescience,medical Recurrent cycles of NREM and REM sleep of about 90 min characterize

normal human sleep. In the successive cycles of the night, the duration of stages 3 and 4 decrease, and the proportion of the cycle occupied by REM sleep tends to increase. The REM episodes occurring late in the night have more eye movement bursts than REM episodes occurring early Inhibitors,research,lifescience,medical in the night.8 Sleep-wake alternation is classically viewed as resulting from the interaction of two regulating processes (circadian-C and homeostatic-S).9 The propensity to sleep or be awake at any given time is a consequence of a sleep debt (process S) and its interaction with Inhibitors,research,lifescience,medical wake-promoting signals coming from the circadian clock (process C) located in the suprachiasmatic nucleus (SCN). This wake-promoting signal opposes the sleep need, which progressively increases from morning awakening, ensuring an even degree of alertness throughout the day.10 At sleep onset, an imbalance between the two opposing influences favor sleep-promoting Inhibitors,research,lifescience,medical signals, and the sleep need and its electrophysiological signature, slow-wave activity,

is at its highest level. Throughout sleep Amisulpride and up to final morning awakening, there is a progressive decline in slow-wave activity reflected by an increase in REM sleep proportion across successive REM/NREM cycles. During the last decade, research lent support to the idea that three interacting neuronal systems (a wakepromoting system, an NREM-promoting system, and a REM-promoting system) are involved in this complex regulation construct. Different structures sending widespread cortical projection and located in the brain stem, the hypothalamus, and the basal forebrain check details constitute the wake-promoting or arousal system (Figure 1).11,12 Glutamatergic brain stem reticular neurons, cholinergic neurons of the basal forebrain, and monoaminergic transmission are largely implicated in the arousal system.

In this light, some scientists have suggested that the use of ATPase inhibitor mobile phones should be restricted in high-risk groups such as children. This study is an attempt to explore the pattern of mobile phone use and its health effects among students from the city of Shiraz,

Iran. Methods: A total of 469 (235 males and 234 females; 250 elementary and 219 junior high school) healthy students participated in this study. The students were randomly selected from three different educational districts of the city. For each student, Inhibitors,research,lifescience,medical a questionnaire regarding the possible sources of exposure to electromagnetic fields or microwave radiation, specially the pattern of mobile phone use, medical history and life style was filled out by interviewers. Results: Only 31.42% of the students Inhibitors,research,lifescience,medical used to use mobile phones. The average daily time of using mobile phones in talk mode was 7.08±21.42 minutes. Not only the relative frequency of mobile phone ownership

in boys was significantly Inhibitors,research,lifescience,medical more than the girls, but also the boys used their mobile phones more frequently. Statistically significant associations were found between the time mobile phones were used in talk mode and some symptoms. Furthermore, a statistically significant association was found between the time mobile phones were used in talk mode and the number of headaches per month, number of vertigo per month, or number of sleeping problem per month. Conclusion: Results obtained in this study show that a large proportion of children in the city of Shiraz use mobile phones. A significant increase was found in some self-reported symptoms among users of mobile phones. These findings Inhibitors,research,lifescience,medical are in line with

what is widely believed regarding the higher vulnerability of children to exhibit symptoms from using mobile phones. The findings and conclusion of the present study should be viewed in the light the nature Inhibitors,research,lifescience,medical of symptoms measurement (self-report) and the knowledge and understandings of the participants about the symptoms. Key Words: Mobile phone, Elementary school, junior high school, students, Iran Introduction Electromagnetic radiation in radiofrequency (RF) region has long been used for different types of information exchange. Modern mobile phones support a wide variety Dipeptidyl peptidase of technical functions from enabling real time two-way communication to data processing. Furthermore, using Wi-Fi that is a protocol for fast data exchange over a wireless network, new mobile phones can access wireless data networks via the internet. In some countries such as the US the users of mobile phones consist about 80% of the population,1 and in some European countries the effective penetration status is “one phone: one person.
