Introduction Relative numerosity discrimination has been studied experimentally in adults

Introduction
Relative numerosity discrimination has been studied experimentally in adults (Burr & Ross, 2008; Durgin, 1995, 2008; Ross & Burr, 2010) infants (Xu & Spelke, 2000), and non-human 4 mu (Brannon et al., 2001; Gallistel, 1989; Leslie, Gelman, & Gallistel, 2008), using psychophysics (Barlow, 1978), fMRI (Harvey et al., 2013; Piazza et al., 2007), and single unit physiology (Nieder, 2005). It has been suggested that there is a ‘visual sense of number’ (Burr & Ross, 2008) and that ‘Vision senses number directly’ (Ross & Burr, 2010) for large numbers of tokens. Here we attempt to discover whether there is indeed a mechanism for numerosity separate from density and size of textures. A common-used strategy for measuring relative numerosity thresholds is to scatter the tokens within a confined area, such as a circle (Burr & Ross, 2008; Durgin, 1995; Raphael, Dillenburger, & Morgan, 2013). In these circumstances, changing the number of tokens must change either the area of the pattern or the density of items. Weber fractions for numerosity are lower when the numerosity change is accompanied by a change in area (Raphael, Dillenburger, & Morgan, 2013), in agreement with other studies showing that a high-precision, one-dimensional mechanism is responsible for area discrimination of circles (Morgan, 2005; Nachmias, 2011). Therefore, experiments with circular textures may overestimate the accuracy of true numerosity discrimination. Randomly interleaving size-varying and density-varying trials (Burr & Ross, 2008; Raphael, Dillenburger, & Morgan, 2013) does not solve this problem, since observers may use whichever of the two independently noisy signals, size or density, is larger on a particular trial (Raphael, Dillenburger, & Morgan, 2013). For these reasons, we thought it desirable to repeat the experiment of Burr and Ross (2008) using stimuli with non-circular polygonal outlines (Fig. 1). We compared four conditions: (1) density-varying trials alone (2) area varying trials alone (3) interleaved area-density trials where the observers made a numerosity discrimination and (4) which is the same as condition 3, but in addition observers had to decide whether the difference was in area or in density. We expected area thresholds for random polygons to be higher than those for circles, and the first question was whether this would also raise thresholds for numerosity. In additional conditions subjects discriminated changes in density or changes in size when numerosity was constant.

Results
Thresholds (Weber Fractions) are shown separately for the different conditions, Trial Types and observers in Fig. 2 and Table 2. The observer’s thresholds (σ) are shown by circles with error bars indicating 95% confidence limits. The colored bars show predictions of a 2-channel size-density model, to be described below. The horizontal lines depict predictions of a 3-channel size-density-numerosity model.
These findings are confirmed by the statistical pairwise comparisons in Table 2.
Fig. 3 and Table 3 compare the Weber fractions of the polygon experiment against those of the previously published circle experiment of the four subjects that took part in both experiments (Raphael, Dillenburger, & Morgan, 2013). It is shown that thresholds on size-varying trials are indeed lower with circular texture than for polygons in all conditions.
In Fig. 4 which shows the Weber Fractions of size varying trials against density varying trials for each observer and condition Lysogen can be seen that the thresholds for size-varying and density-varying trials, in size, density and number conditions are indeed similar. In trials of the Extended Conditions when numerosity is kept constant and density and size vary reciprocally, discrimination is significantly impaired (significant in 9 out of 10 comparisons, 5 observers×2 Trial Types). Though, comparing the Single Trial Type conditions for size and density with the same Trial Type of the extended conditions of size and density reveals no increase in threshold for size judgment. Hence, observers are not worse in density and size judgments when stimuli are interleaved with trials that offer a less reliable cue.

Results
Tissue injection-site reactions were not observed in any calves following vaccination or treatment administration. No clinical signs of BRD were observed in any of the calves during the experimental period. Concentrations of Se and Cu in most feedstuffs (except for Cu levels in hay) were lower than the suggested requirements for growing dairy calves (0.3 and 10mg/kg of Se and Cu, respectively; NRC, 2001). Concentrations of Zn in grass and Mn in feed supplement were lower than the requirements (32 and 22mg/kg, respectively; NRC, 2001). However, the needs for Zn and Mn were properly satisfied by the other two feed components throughout the experimental period (Table 1).

Discussion
In this study calves had adequate liver tissue concentration of all the study trace p2y receptor assessed at all sampling dates according to standard reference values (Herdt and Hoff, 2011). Administration of ITM resulted in increased concentrations of liver Se (on days 21 and 56), Cu (on day 56) and Mn (on day 56) compared to saline injected calves. Therefore, injection of trace minerals at the beginning of the study and again 21days later improved the Se, Cu, Zn and Mn status of the ITM calves compared to the control calves over the period of the study.
Previous studies have shown that supplementation with injectable Se, Cu, Mn and Zn improved serum and liver levels of these minerals compared to those in saline injected calves (Arthington et al., 2014; Arthington and Havenga, 2012; Pogge et al., 2012). In the current study administration of ITM contributed to increase and/or mitigate the abrupt decay in liver concentration of trace minerals in dairy calves that received two doses of the vaccines utilized. Similar to this study a significant reduction in Se, Cu and Zn concentrations has been previously reported in calves following vaccination (Arthington and Havenga, 2012; Droke and Loerch, 1989) or challenge (Chirase et al., 1994) and might be associated with the utilization of these nutritional elements to develop an immune response.
Trace mineral status and requirements may vary with the stage of growth and production (NRC, 2001). It has been documented that liver reserves of trace minerals in cattle decrease with the age, reaching significantly decreased levels by 6–7 months of age, if no mineral supplementation is provided (Puschner et al., 2004a,b). Arthington et al. (2014) reported more than 60% decrease in liver Se concentrations in calves from 150 to 250days of age, which might have negative consequences on overall health, feed efficiency and performance. In this study, we used young calves (3.5 months of age) that were raised on an acceptable nutritional regime from immediately after birth until the end of the trial. This might explain the adequate mineral status in both groups throughout the experimental period.
Administration of ITM concurrently with MLV vaccination enhanced the ultimate level and shortened the time needed to reach expected antibody production against BVDV1, demonstrated by increased SN titers as well as a higher proportion of calves that seroconverted on day 28 after primary vaccination compared to the control calves. This quicker BVDV-specific antibody response elicited by an MLV vaccine delivered concurrently with ITM might be of significant value by conferring earlier protection following vaccination. This could be particularly important in newly received, highly stressed cattle that are at high risk of respiratory viral infections. A rapid increase in serum neutralizing antibodies against BVDV after vaccination may be beneficial to prevent infection and disease development. The antibodies may neutralize extracellular virus particles, inhibiting attachment of the virus to host cells, and contribute to antibody dependent cell mediated cytotoxicity (Forthal, 2014).
Similarly, previous reports have shown that ITM enhanced humoral immune response to pathogens of clinical significance in cattle production, including BVDV (Roberts et al., 2015), BHV1 (Arthington and Havenga 2012), E. coli (Panousis et al., 2001) and Pasteurella haemolytica (Droke and Loerch, 1989). In the study performed by Arthington and Havenga (2012), administration of trace minerals concurrently with an MLV vaccine to steers induced a significant increase in BHV1 serum neutralizing antibody titers on days 14, 30, and 60 post-vaccination compared to the base line titers on day 0 and to the titers in the saline injected steers.

The clinical occurrence rate of BTB in different cattle breeds

The clinical occurrence rate of BTB in different cattle breeds suggests that genetic factors may play a crucial role in susceptibility to BTB (Vordermeier et al., 2012; Alfano et al., 2014). Previous studies have identified several genetic factors which may enhance or reduce susceptibility to BTB and influence development of the disease (Acevedo-Whitehouse et al., 2005; Song et al., 2014). Therefore, selective breeding with BTB-resistant genetic markers might represent a new approach to supporting BTB control (Alfano et al., 2014).
The Toll-like receptors (TLRs) recognize pathogen-associated molecular patterns (PAMPs), and play fundamental roles in pathogen recognition and activation of innate immunity. The TLRs include 13 members (TLRs 11-13), and different TLRs can recognize different glutathione s-transferase from diverse pathogens (Beutler, 2004; Dasari et al., 2008). Single-nucleotide polymorphisms (SNPs) in the Toll-like receptor (TLR) genes have been reported to associate with susceptibility to tuberculosis indifferent animal species as well as humans (Alfano et al., 2014). To date, variants in TLR1, TLR2, TLR4, TLR6 and TLR9 have been associated with susceptibility to tuberculosis in humans (Ma et al., 2010; Selvaraj et al., 2010; Xue et al., 2010); additionally, variants in TLR2, TLR4 and TLR9 are associated with susceptibility to BTB in water buffalo (Alfano et al., 2014), and variants in TLR1 and TLR6, but not in TLR9, have been shown to be associated with susceptibility to BTB in Chinese Holstein cattle (Song et al., 2014; Sun et al., 2012). However, these results seem to be quite diverse.
TLR2 is mainly localized on immune cells and respiratory epithelial cells, and recognize mycobacterial membrane components, including Mycobacterium (Akira et al., 2001). Then the TLR2 and membrane component complex connect adaptor molecules such as MyD88 and TRIF and activate MyD88-dependent and TRIF-dependent signaling pathways in macrophages or other cells. These responses lead to the secretion of inflammatory cytokines, chemokines, interferon and antimicrobial peptides (Kawai and Akira, 2010), resulting in the direct killing of the infected mycobacterial pathogens and the induction of adaptive immunity (Saiga et al., 2011). TLR2 is reported to be able to initiate the host defense against tuberculosis, especially in chronic infection (Kleinnijenhuis et al., 2011; Gopalakrishnan and Salgame, 2016). The objective of this study was to identify SNPs in the TLR2 gene of Chinese Holstein cattle and assess their possible associations with BTB.

Materials and methods

Discussion
To date, hundreds of SNPs have been identified in TLR-family genes. Some of these SNPs have been reported to associate with susceptibility to not only tuberculosis (Kleinnijenhuis et al., 2011), but also with Helicobacter pylori infection (Ravishankar Ram et al., 2015) and vitiligo (Traks et al., 2015). Among the TLRs, TLR2 is believed to be important in the initiation of the innate host defense against tuberculosis (Kleinnijenhuis et al., 2011). TLR2 also has a janus function in vivo as mediator of the role of bacterial products in balancing pro- and anti-inflammatory immune responses in M. tuberculosis infection (Piermattei et al., 2016). Since TLR2 played fundamental roles in pathogen recognition and activation of innate immunity, gene variations in the TLR2 gene region might results in a significant change in the ability of immune cells to respond to M. bovis infection.
Some functional and genetic studies have concluded that SNPs or other gene variations in the TLR2 gene region have the ability to modify gene expression level or alter the immune response to PAMPs (Lorenz et al., 2000; Merx et al., 2007; Mrabet-Dahbi et al., 2008). TLR2 knockout mice exhibited enhanced susceptibility to infection with M. tuberculosis compared with wild-type mice and developed chronic lethal pneumonia (Kleinnijenhuis et al., 2011). Additionally, studies have indicated that some SNPs in the TLR2 gene might be associated with susceptibility to tuberculosis in humans and in water buffalo (Song et al., 2014; Alfano et al., 2014). However, to the best of our knowledge, the relationship between bovine TLR2 gene polymorphisms and the risk of BTB in Chinese Holstein cattle was unclear. In this study, our results showed that no SNPs within the TLR2 coding gene were associated with BTB susceptibility in Chinese Holstein cattle.

order continine Featuring different countries in research on CGs

Featuring different countries in research on CGs is valuable due to important variations between meanings attached to CGs and their impact in different parts of the world. For instance in USA, order continine gardening can be understood as “a socialistic enterprise reflecting communitarian value” (Guitart et al., 2012 p. 369). Describing various activities that CGs members undertake as a community Glover states “ In this sense, community gardens are less about gardening than they are about community’’ (Glover, 2004 p.143). As oppose to North America, in socialist Cuba the motivation for establishment of urban gardens is predominantly food production resulting from nation’s oil vulnerability (Guitart et al., 2012). Examining urban agriculture in Cape Town, Slater (2001) found that local women perceived food gardening as a source of comfort following outbreaks of violence in the townships, as symbol of stability and as means to negotiate control over household food consumption. In later research Wills et al. (2010) found that in CG in Johannesburg the main focus was on provision of food and capacity building. Apartheid consequences of spatial segregation required participants to commute long distances to reach the CG making it difficult for participants to meet and socialize (Wills et al., 2010).
In Europe the common arrangement for collective urban gardening is allotment gardens. Some allotments are considerably old (over 100 years), the gardeners hold property rights that are often long term and stable, individual gardens and areas for cultivation are not open for public and the application process for land is formal and requires considerable fees (Bendt et al., 2013). The primary category of urban community gardens in USA on the other hand is the neighborhood garden where at times plots are cultivated individually and other times communally. The neighborhood gardens are often assisted by NGOs and governmental programs, at times free of charge or ask for low fees and have much less stable leases and rigid regulations comparing to allotment gardens of Europe (American Community Garden Association, 1998; Lawson, 2005). The most common challenge faced by USA gardeners is secure land access. In other countries however, issues such as soil contamination, lack of water, safety issues, and theft of tools and vegetables were addressed as greater concerns (Guitart et al., 2012).

Israeli community gardens
Establishment of urban agriculture in early 20th century Israeli cities followed Zionist ideology which glorified agriculture as an instrument both for personal development, forging a new Jewish identity, and as a national enterprise. The Zionist Labour movements tried to integrate agriculture into urban workers’ lifestyles. The need for housing due to massive immigration waves and the gradual dissolution of the agricultural ethos led to a decline of urban agriculture until the 1990’s with only few urban farms (Alon-Mozes and Amdur, 2010). Since the early 1990s urban land cultivation practices are gaining popularity in the form of CGs. At the time of order continine this research completion (2012), approximately 120CGs were mapped by The Organization of Activists for Community Gardens in Israel but by 2015 this number increased to 500 mapped CGs. Jerusalem, Israel’s capital had 37CGs in 2013 and today it lists more than 60CGs (Jerusalem Municipality, 2016). For comparison there are 100CGs and 918 allotment gardens documented in Berlin (Senate Department for Urban Development and the Environment Allotment Gardens, 2015; Wunder, 2013) and there are currently some 3 million allotment gardens in Europe (Barthel et al., 2010). In USA, There are 600CGs in NY City (GreenThumb, 2016), some 275 in Minneapolis (Homegrown Minneapolis, Community Gardens, 2016) and approximately 200CGs are listed in Boston (Boston Natural Areas Network, 2016).
CGs steadily continue to appear in central cities of Israel as well as peripheral towns and small community settlements. While it is difficult to estimate the national scope of CG users some sporadic approximations do exist. For instance, JDC (Joint Distribution Committee) Israel (Joint) survey of CGs supported by the organization roughly estimates 3000 participants in some 130 gardens (Joint Israel, 2012). Bearing in mind the small size of the country and the span of time since the establishment of the first CG the scope and the growth of the phenomena is considerable.

Introduction
As cities grow, development often occurs outwards. Without corresponding net population growth, this can leave vacant buildings and land in the dense urban matrix (Bowman and Pagano, 2004; Bontje, 2004). These vacant spaces come in many forms and sizes, and include everything from severely contaminated brownfields to foreclosed residential properties where buildings may have been partially or completely demolished. Sometimes called greenfields, wastelands, or abandoned, derelict or uncultivated land, these spaces comprise an extensive network in urban areas. While these various jnk inhibitors of land have subtle differences, they are often lumped together because there is no single, broadly accepted definition for vacant land (Bowman and Pagano, 2000; Bowman and Pagano, 2004; Kremer et al., 2013).
Cities with more than 250,000 inhabitants generally have between 12.5-15% vacant land by area at any given time (National Commission on Urban Problems, 1968; Bowman and Pagano 2000). These vacant lots do not occur randomly throughout the urban matrix but tend to be concentrated in low-income neighborhoods (Brulle and Pellow, 2005; Kremer et al., 2013). Vacancy is usually perceived negatively and typically correlates with increased crime and reduced property values (Hoffman et al., 2012). In extreme cases, the negative connotations of high vacancy can overshadow positive community assets (Garvin et al., 2013). However, studies in New York City demonstrate that vacant lots can also be viewed as a valuable resource for local economies, communities, and environments (Bowman and Pagano, 2004; Kremer et al., 2013). For this reason, there has been interest in transforming these spaces into informal greenspace (Burkholder, 2012; Rupprecht and Byrne, 2014) within the urban matrix. Such transformations could increase urban sustainability, by improving the balance among environmental protection, economic development, and social wellbeing (Wu, 2010), and promoting development that meets the needs of the present without compromising the ability of future generations to meet their own needs (Brundtland, 1985).

Objective and approach
This review was motivated by the three pillars of sustainability (i.e., environmental, economic, and social; UN, 2002; Andersson, 2006) to take an interdisciplinary approach to evaluating vacant lot restoration. We seek to synthesize ecological, economic, and social motivations, methods, and outcomes of restoring biodiversity to vacant lots and to pose recommendations for future projects. We focus specifically on vacant lots as they are fundamentally different from other kinds of urban green space (e.g., community gardens, parks, etc.) in terms of human involvement. Other reviews have explored biodiversity (Bonthoux et al., 2014) and potential to provide ecosystem services (Kim, 2016) in vacant lots, and tools for evaluating brownfield restoration projects (Pediaditi et al., 2010). Relatedly, a recent brief produced by the Vacant Property Research Network (Heckert et al., 2015) highlights benefits of the broader field of ‘urban greening’. However, no paper focuses specifically on restoring biodiversity in vacant lots. Furthermore, while there is certainly multi-disciplinary interest in restoring vacant lots, true interdisciplinary work bridging ecological, economic, and concepts in restoration is limited.
To find literature, we performed searches using Web of Science© and Google Scholar© that included combinations of key terms “vacant lots” “greenfields”, “biodiversity”, “urban”, and “restoration” along with discipline specific terms including “public health”, “value”, “ecosystem services”, “greening”, and “cost”. Using these search terms, we found 24 papers focused specifically on biodiversity and restoration in vacant lots. From these initial resources, we utilized bibliographies and searches of other publications by relevant authors to compile an interdisciplinary works cited that includes 117 sources focused mostly on Europe (n=22) and the United States (n=34) when they were geographically explicit. Many papers were interdisciplinary, but over half (n=64) addressed aspects of ecology, 35 addressed social sciences, 21 urban planning, 18 economics, and 8 public health. Because there is not a large body of literature specifically on restoring biodiversity in vacant lots, we also draw from other relevant bodies of literature when helpful, but maintain a focus on peer-reviewed literature.

Introduction
There were 25.8 million people in the United States, or 8.3% of the population, who had diabetes in 2010 (Centers for Disease Control [CDC] 2011). Depending on the criteria, diabetic polyneuropathy is estimated to occur in 50% to 90% of individuals who have had diabetes longer than 10 y (Lehtinen et al. 1989; Pirart 1978; Vinik 1999). Pain evoked by diabetic polyneuropathy can degrade quality of life. Unfortunately, the pathogenesis of diabetic polyneuropathy is not well understood, though it is currently believed that some factors lead to reduced Na+/K+ ATPase activity and vasoconstriction, thereby reducing endoneurial blood flow and causing nerve hypoxia (Veves and King 2001). Oral medications are typically used for pain relief, and capsaicin cream and lidocaine patches, which are applied topically on the skin, can also help ease pain. Nonetheless, some side effects induced by oral medications still occur. Physical therapies have been proposed for the treatment of painful diabetic polyneuropathy, including acupuncture (Abuaisha et al. 1998), electrical vessel stimulation (Lin et al. 2005), electrical nerve stimulation (Hamza et al. 2000), electrical mibefradil stimulation (Daousi et al. 2005), static magnetic field therapy (Weintraub et al. 2003), low-intensity laser therapy (Zinman et al. 2004) and near-infrared treatment (Leonard et al. 2004). However, the outcome of acupuncture relies greatly on the individual experience of clinicians, and it is as invasive as electrical stimulation. For magnetic field, laser and near-infrared treatments, further studies are needed to prove their effectiveness. In addition, a modality that can instantly soothe the pain is desired by patients with diabetic polyneuropathy because the pain usually occurs at night.
Medical ultrasound has been broadly used for clinical diagnosis; more recently, the U.S. Food and Drug Administration (FDA) approved a high-intensity focused ultrasound (HIFU) system designed specifically for the non-invasive treatment of uterine fibroid tumors (Okada et al. 2009; Taran et al. 2009). Nerve conduction inhibition using ultrasound for pain management has been actively investigated for nearly 50 y (Ballantine et al. 1960; Foley et al. 2007). Experiments in surgically exposed cat spinal cords have revealed that reversible effects on reflexes are induced with 3 to 300 bursts of ultrasound exposure, with a duration of 50–300 ms at 2.7 MHz and a repetition rate of once per 0.5–3 s (Young and Henneman 1961b). Ultrasound-induced temperature elevation has been verified as one of the mechanisms underlying nerve conduction block (Lele 1963). In vivo experiments in Sprague–Dawley rats indicated that partial and temporary nerve blocks or permanent and complete nerve degeneration could be achieved using HIFU exposures of 390 or 7890 W/cm2, for 5 s at 5.7 MHz, respectively (Foley et al. 2008). However, the animal subjects used in the above-mentioned experiments were normal, and the nerves were not neuropathic. It is thus necessary to further investigate the effects of HIFU on neuropathic nerves. Conversely, the electrically stimulated compound action potential captured in the above-mentioned experiments is the sum of sensory and motor action potentials, so the influence of HIFU on the sensory nerve is uncertain. In fact, only sensory nerve block is needed for pain relief.

Introduction
There were 25.8 million people in the United States, or 8.3% of the population, who had diabetes in 2010 (Centers for Disease Control [CDC] 2011). Depending on the criteria, diabetic polyneuropathy is estimated to occur in 50% to 90% of individuals who have had diabetes longer than 10 y (Lehtinen et al. 1989; Pirart 1978; Vinik 1999). Pain evoked by diabetic polyneuropathy can degrade quality of life. Unfortunately, the pathogenesis of diabetic polyneuropathy is not well understood, though it is currently believed that some factors lead to reduced Na+/K+ ATPase activity and vasoconstriction, thereby reducing endoneurial blood flow and causing nerve hypoxia (Veves and King 2001). Oral medications are typically used for pain relief, and capsaicin cream and lidocaine patches, which are applied topically on the skin, can also help ease pain. Nonetheless, some side effects induced by oral medications still occur. Physical therapies have been proposed for the treatment of painful diabetic polyneuropathy, including acupuncture (Abuaisha et al. 1998), electrical vessel stimulation (Lin et al. 2005), electrical nerve stimulation (Hamza et al. 2000), electrical mibefradil stimulation (Daousi et al. 2005), static magnetic field therapy (Weintraub et al. 2003), low-intensity laser therapy (Zinman et al. 2004) and near-infrared treatment (Leonard et al. 2004). However, the outcome of acupuncture relies greatly on the individual experience of clinicians, and it is as invasive as electrical stimulation. For magnetic field, laser and near-infrared treatments, further studies are needed to prove their effectiveness. In addition, a modality that can instantly soothe the pain is desired by patients with diabetic polyneuropathy because the pain usually occurs at night.
Medical ultrasound has been broadly used for clinical diagnosis; more recently, the U.S. Food and Drug Administration (FDA) approved a high-intensity focused ultrasound (HIFU) system designed specifically for the non-invasive treatment of uterine fibroid tumors (Okada et al. 2009; Taran et al. 2009).

In fact, only sensory nerve block is needed for pain relief.

Currently two basic techniques are used in sonoelastography

Currently, two basic techniques are used in sonoelastography of the mammary glands: static elastography, also called strain imaging, and dynamic elastography, also called shear wave elastography (SWE) (Bamber et al. 2013). In strain imaging, the elastograms obtained indicate the relative stiffness (strain) of the (-)-JQ1 examined (semiqualitative method) by means of a color map (Itoh et al. 2006; Wojcinski et al. 2010). With the acquired measurements, the strain ratio (SR) may be calculated. SR expresses the relationship between the strain of the adjacent tissue and the strain of the assessed lesion (semiquantitative method) (Stachs et al. 2013).
In the largest published multicenter trial to date, Berg and co-workers reported that adding the features of SWE examination to the assessment of focal lesions in BI-RADS-US classification improves the specificity of the outcomes, leaving sensitivity unaffected (Berg et al. 2012; Cosgrove et al. 2013). Cosgrove et al. (2012) proved that this method is reproducible, especially in calculating the maximal and mean Young\’s moduli (E). Yoon et al. (2013), however, reported that this method may have limitations resulting from the size of the mammary glands or focal lesions and the depth at which they are located.
In publications concerning the usefulness of sonoelastography in the differential diagnosis of focal breast lesions, the authors pay attention to the usefulness of various indicators that in a quantitative way evaluate tissue stiffness in the lesion and its adjacent tissues (Berg et al. 2012; Evans et al. 2010, 2012).

Physical Basics of Dynamic Elastography
Ultrasound reveals differences in the acoustic impedance of tissues, which is expressed as a product of density and longitudinal speed (depending on the modulus of elasticity). The elasticity of materials is their ability to return to their original shape after being subjected to external force or distorting stress. Fluids resist changes to their volume, but not to their shape; they only have volumetric elasticity. Solid bodies resist changes to their shape and volume; Back mutation have rigidity—shear elasticity and volumetric elasticity. The change in dimensions or shape is called strain. It occurs as a result of force, that is, stress, acting on the surface.
In a homogeneous isotropic solid body the stress/strain ratio is constant and is called the modulus of elasticity. Three moduli (N/m2) are commonly used to describe elasticity: (i) Young\’s modulus (longitudinal elasticity, E = [stress]/[strain]); (ii) shear modulus, μ; and (iii) bulk modulus, K.
When subjected to stress, material may contract in directions transverse to the direction of stretching or may expand in directions transverse to the direction of compression. This effect is expressed by Poisson\’s ratio:
The interdependence between Young\’s modulus, shear and bulk moduli and Poisson\’s ratio is given by two linear constitutive equations:
The velocities of mechanical longitudinal wave cl and transverse (shear) wave cs in a solid body are equal:where ρ denotes material density.

Methods
Breast ultrasound examinations in 76 women with 84 solid focal lesions (BI-RADS-US [Breast Imaging Reporting and Data System for Ultrasound] categories 3–5) were performed at the Maria Skłodowska Curie Oncology Institute in Warsaw. The patients were qualified to undergo an US scan because of abnormalities detected in their breasts in physical or imaging examinations performed beyond the Institute. B-Mode scans of the breasts and axillary fossae were performed in accordance with the standards of the Polish Ultrasound Society (with the division of BI-RADS-US category 4 into 4a and 4b) (Jakubowski 2008, 2009). Next, an SWE examination was conducted using the Aixplorer ultrasound system (SuperSonic Imagine) with a linear array transducer of 4–15 MHz.
Quantitative measurements of stiffness in focal lesions were taken in regions of interest placed in any area of the elastogram. The following values were determined: mean (Eav), maximal (Emax) and minimal (Emin) Young\’s moduli, as well as standard deviation.
