description: Despite the acknowledged impact of the tumor stroma on breast cancer development and progression, the molecular basis of such effects remain partially unexplained. We previously reported that breast cancer-associated fibroblasts (CAFs) induced epithelial-mesenchymal transition and an increase in cell membrane fluidity and migration speed in poorly (MCF-7) and highly invasive (MDA-MB-231) breast cancer cells. More recently, in order to better define the mechanisms responsible for the CAF-promoted tumor cell migration, we investigated the role of Stearoyl-CoA desaturase 1 (SCD1), the main enzyme regulating membrane fluidity, and demonstrated its CAF-triggered up-regulation as well as its crucial role in the migratory ability of the above tumor cells. Besides SCD1 induction, a CAF-promoted enhancement in the protein level and/or activity of the SCD1 transcription factor, the sterol regulatory element-binding protein 1 (SREBP1), was observed. Moreover, the influence of stroma-derived signals in cancer cell migration speed was proved by cell tracking analysis in the presence of neutralizing antibodies to hepatocyte growth factor, transforming growth factor-β or basic fibroblast growth factor, where a marked reduction or abolishment of the fibroblast-triggered increase in cancer cell migration speed was observed. In the last part of this study, in order to verify if soluble CAF-derived factors stimulate breast cancer cell migration in a SCD1-dependent manner, tumor cells were exposed to CAF-conditioned medium (CM) and their migration evaluated by scratch assay in the presence of a small molecule inhibitor of SCD1. Moreover, to assess if the induction of SCD1 expression by CAFs might occur via SREBP1, the desaturase levels were also determined in SREBP1-inhibited tumor cells. These latest investigations indicate that SCD1 contributes to the promotion of breast cancer cell migration by CAF-derived soluble factors, since the desaturase inhibition completely suppressed the stimulatory effect of CAF-CM on tumor cell migration. SREBP1 inhibition impaired CAF-mediated up-regulation of SCD1 in poorly invasive but not in highly invasive tumor cells, in which SREBP1-independent mechanisms may account for the enhancement of SCD1 levels. These results provide further insights in understanding the role of CAFs in promoting tumor cell migration, which may help to design new stroma-based therapeutic strategies.

description: The Sunyaev-Zel'dovich (SZ) effect has long been identified as one of the most important secondary effects of the Cosmic Microwave Background (CMB). On the one hand, it is a potentially very powerful cosmological probe providing us with additional constraints and on the other hand it represents the major source of secondary fluctuations at small angular scales (l > 1000). We investigate the effects of the SZ modelling in the determination of the cosmological parameters. We explore the consequences of the SZ power spectrum computation by comparing three increasingly complex modelling, from a fixed template with an amplitude factor to a calculation including the full cosmological parameter dependency. We also examine the dependency of the cosmological parameter estimation on the intra-cluster gas description used to calculate the SZ spectrum. We show that methods assuming an SZ template bias the cosmological parameters (by up to 2 sigmas on sigma_8) when the cosmology used in the template deviates from the reference one. A joint CMB-SZ analysis with a full cosmological dependency of the SZ spectrum does not suffer from such biases and moreover improves the confidence intervals of sigma_8 and Omega_{dm}h^2 (2.5 and 2 times respectively) with respect to a pure CMB analysis. However, the latter method is quite sensitive to the intra-cluster gas parameters and hence requires extra information on the clusters to alleviate the induced biases.

description: Atmospheric pressure cold plasma (APCP) is a novel tool for tissue disinfection that has also positive effects on wound healing. We recently reported that two minutes of APCP, generated through the ionization of helium gas, exerted an antimicrobial effect without significant damage to cells and tissues (1), effects that may induce also fibroblast proliferation (2). The aim of the present study was to ascertain the molecular changes induced by 2min APCP in vitro and in vivo using human dermal fibroblasts obtained from four different donors and an in vivo mouse skin wound healing model. Scratch wound healing assay on dermal fibroblasts exposed for two min to APCP showed an improved cell migration, whereas RT-PCR analysis revealed an increased expression of cytokines and growth factors involved in wound healing, such as IL6, FGF2 and TNFα. The in vitro effects of APCP exposure on dermal fibroblast viability demonstrated that two min of plasma application did not cause changes in the viability of two cell preparations but induced a significant increase in viability of fibroblasts from the other two donors, when compared to the untreated control (p<0.05). Apoptosis was not altered when analyzed by the Tunel test in any dermal fibroblast cultures. The in vivo wound healing model confirmed that APCP improved tissue regeneration in mice. Expression of inflammatory cells in both control and treated tissues were higher at three days after treatment, suggesting an increased immune defense in the early phases of wound healing. Moreover, a reduction of collagen I staining at 12 days after wounding was observed, compared to both 3 and 9 days after wounding. At 12 days, a complete attachment of regenerated skin was demonstrated by increased staining for laminin, compared to day 9. Furthermore, at 12 days from APCP treatment, we observed a thicker epidermal layer after H&E staining. In conclusion, our in vitro and in vivo results showed that APCP maintains or increases cell viability and migration and induces a transitory alteration of the expression of genes involved in wound repair.

description: Calcified tissues are well known microscopically, but the diagnostic potential of bone micro-anatomy is still underestimated. The shape and size of osteons or of lamellar bone are unique and fundamental for determining the species of origin of human remains, and for understanding age, disease, and trauma; thus micro-anatomy is crucial to many disciplines, from archaeology to forensic medicine. This presentation aims at illustrating and reviewing all such applications. The first question arising when studying skeletal remains is: “is it human?”. Macroscopic analysis alone can sometimes be insufficient in understanding if they belong to a human or to another animal; in such cases, the microscopic characteristics can be the only instrument capable of providing a reply, by evaluating the presence of osteons, their pattern and distribution, as well as the their metrical parameters [1]. Secondly, bone tissue formation as well as the constant bone remodeling process result in a strong correlation between the age of an individual and both the tissue pattern and the number of osteons per unit area in a bone cross-section, parameters on which most of the histological age-estimating methods are based. These methods are particularly important in distinguishing subadults from adults, and, among the latter, in estimating age where other methods result unsatisfactory [2]. Bone histology can also be diagnostic in the research for pathological diseases and traumatic events, especially with concern to the moment in which a trauma occurred [2]. Finally, the type and degree of microscopic damage can give some insight into the environmental surroundings in which the bone was, and a taphonomic profile useful for the verification of taphonomic events and clues on the post mortem interval of the sample [3]. All these contributions demonstrate that even just a small piece of bone, in fact a microscopic part of it, is fundamental and can sometimes be the only instrument for the correct interpretation of the story that human remains can tell.

description: Exercise is a beneficial adjunct therapy to maintain or enhance quality of life in cancer patients. Recently, few studies demonstrated a correlation between high concentrations of IL-6 and a poor survival. This depends on the equilibrium between the concentrations of IL-6 and sIL-6R. Exercise induces a beneficial increase in circulating IL-6 (1).
Fresh fragments of solid C26 tumor were inoculated in healthy 3 months-old mice (n=230, M=115 and F=115). The experimental procedure were 12 weeks long. During the first 6 weeks, mice were randomly assigned to one of the experimental conditions: sedentary (SED) or progressive training (TRP). After the first 6 weeks, all mice were inoculated with a fresh fragment of tumor. All trained adult mice after the tumor inoculation were randomly assigned to a different training program: low intensity training (TRL), moderate intensity training (TRM) and high intensity training (TRH). Mice run 5 days per week on a Rota-Rod following one of the specific training program (TRP ,TRL, TRM and TRH) (2). After tumor inoculation the mice were daily weighted and tumor size monitored until death. Moreover, 8 mice for each group were sacrificed when cachexia occurred (>9% body weight loss), and blood samples were stored for CBA Enhanced flex set flow-cytometric assays (IL-6 and TNF-alpha).
The TRM and TRH training protocol performed by trained adult male mice extend the median survival compared to the sedentary adult mice and trained female mice. Interesting the beneficial effect of exercise seemed to be mediated extending the survival days. Significant high blood levels of IL-6 were recorded among the male trained mice (TRM and TRH) groups in comparison with sedentary adult mice and trained female mice (TRM and TRH).
The results suggest that endurance exercise as adjuvant therapy is gender and physical training level specific. This effect seems to be mediated by IL-6 blood levels.

description: Heat shock protein (Hsp60) is a mitochondrial chaperonin whose unconventional cellular localizations and functions are discovered day by day. In the present study, the levels of Hsp60 in fibres of the soleus muscle and its correlation to the expression of four isoforms of peroxisome proliferation-activated receptor-γ (PPAR-γ) coactivator-1α (PGC1α) were investigated in 72 young (7-weeks old) healthy male mice (BALB/c AnNHsd) at baseline and after completing a 6-week endurance training program. The mice were assigned to one of the two experimental groups: SED (sedentary) or TR (trained). Short-term overexpression of hsp60, achieved by in vitro plasmid transfection, was then performed to determine whether this chaperonin could have a role in the activation of the expression levels of PGC-1α isoforms. The levels of Hsp60 protein were fibre-type specific in the posterior muscles at baseline, and endurance training increased its content in type I muscle fibers. Concomitantly with the increased levels of Hsp60 released in the blood stream of trained mice, mitochondrial copy number and the expression of three isoforms of PGC-1α increased. Overexpressing hsp60 in cultured myoblasts induced only the expression of PGC-1 α1, letting us suppose a direct correlation between Hsp60 overexpression and PGC-1 α1 activation. Overall, these results suggest that during endurance training Hsp60 is upregulated and activates the mitochondrial biogenesis pathway, probably as a response to the oxidative stress induced by exercise. This study reveals a molecular response of skeletal muscle to a mechanical stress induced by training which involves the molecular chaperonin Hsp60 and the transcriptional co-activator PGC-1 α1. The role of these proteins in aerobic adaptation and pathological conditions as cancer cachexia warrants further investigations.

description: Autophagy represents a physiological mechanism responsible for cell homeostasis and its deregulation is involved in several conditions related to muscle mass loss such as aging, anorexia, inflammatory diseases, cancer, disuse and immobilization (1). In our previous work, double membrane vesicles, suggestive of autophagy, appeared after chemotherapeutic treatments in C2C12 myotubes (2). Here, to better understand the autophagic behavior, skeletal muscle cells have been exposed to cisplatin, etoposide and staurosporine and their effects have been investigated by means of morphological, cytofluorimetric and functional analyses. Ultrastructural observations evidenced the presence of autophagic vacuoles containing abnormal mitochondria, nuclear materials and membranes. Flow cytometry evaluation of lysosomal compartment stability revealed an autophagic pattern increase, particularly after cisplatin and staurosporine exposure, suggesting the presence of a cell death mechanism. Since autophagic deregulation is involved in different muscle diseases, further studies are in progress to evaluate possible strategies, such as protein ipo/iper supplementation, to prevent the abnormal autophagic activation induced by chemical triggers, which lead to muscle atrophy (3).

STREETS AND OPEN SPACES: COMPARING MOBILITY AND URBAN FORM AT ANGAMUCO AND CHUNCHUCMIL, MEXICO

description: Angamuco and Chunchucmil are two of the few Mesoamerican cities with relatively complete street maps. These maps provide a rare opportunity to study how the bulk of the population moved through cities, how people worked together to organize a network of paths and open spaces, what kind of interactions these features afforded, and how they contributed to the formation of social identities. Having found that space syntax methods confirmed intuitive understandings without generating new findings, we apply a segment (paths) and node (intersections) analysis to both sites. With these analyses we recorded and characterized segment variables such as width, length, form, and curvature, and node variables such as size, form, and number of linked segments. Many of the nodes at both sites are open spaces, allowing us to register details about the configuration of shared public spaces that are less formal than monumental plazas. The analyses revealed neighborhood differentiation, local-level coordination of labor, and intentional efforts to create markets or spaces of assembly that may have complemented collective governance proposed for both sites. While Angamuco and Chunchucmil differ in terms of the general pattern of their pedestrian networks, they share similarities in terms of density of paths and types of intersections.

description: Tyrosol (4-(2-hydroxyethyl) phenol) (Tyr) is a well-known phenolic compound that is mainly present in extra-virgin olive oil and white wine. It has many beneficial properties, such as antioxidant, antimicrobial and anti-inflammatory activity and has been reported to have scavenging effects on peroxynitrite and superoxide anion (1). Moreover, Tyr exhibits anticancer, anti-depressant, anti-stress, cardioprotective, antiosteoporosis, anti-inflammatory and neural protective effects (2). Here Tyr effect has been investigated in a skeletal muscle cell line exposed to known oxidative stress inducers (3, 4). To evaluate Tyr protection against oxidative stress and cell death, ultrastructural and functional analyses have been carried out. In particular, mitochondrial probes used and analysed at confocal microscopy. All techniques confirmed that Tyr is able to prevent skeletal muscle damage, to preserve mitochondrial membrane integrity and to down regulate oxidative stress levels. These findings demonstrated Tyr antioxidant property in skeletal muscle cell too, suggesting, for this molecule, an important potential role in all muscle diseases related to reactive oxygen species production.

description: Quantum-confined semiconductor structures are the cornerstone of modern-day electronics. Spatial confinement in these structures leads to formation of discrete low-dimensional subbands. At room temperature, carriers transfer among different states due to efficient scattering with phonons, charged impurities, surface roughness and other electrons, so transport is scattering-limited (diffusive) and well described by the Boltzmann transport equation. In this review, we present the theoretical framework used for the description and simulation of diffusive electron transport in quasi-two-dimensional and quasi-one-dimensional semiconductor structures. Transport in silicon MOSFETs and nanowires is presented in detail.

description: Aging is an universal, inevitable and multifactorial biological process, which causes progressive loss of function and an increased risk of death. Free radicals have been implicated in aging process, causing cumulative oxidative damage to crucial macromolecules and are responsible for failure of multiple physiological mechanisms [1]. Muscle mass and function are gradually lost during aging leading to neuromuscular disorders (such as fibromyalgia, sarcopenia, etc.). The indoleamine melatonin is able to prevent oxidative stress both through its free radical scavenging effect and by increasing endogenous antioxidant activity and so protecting against oxidative damage induced by drugs, toxins and different diseases [2]. Herein, we evaluated the susceptibility of rat L6 skeletal muscle cells to induced oxidative stress due to the exposure of cells to hydrogen peroxide and the potential protective effects of the pre-treatment with melatonin (MelapureTM by Flamma S.p.A.), compared to the known beneficial effect of alpha-lipoic acid. Our results showed that hydrogen peroxide-induced obvious oxidative stress, increasing the expression of tumour necrosis-alpha and in turn of nuclear factor kappa-B, overriding the endogenous defence mechanisms and alterating the mitochondrial structure. In contrast, the pre-treatment with melatonin of the hydrogen peroxide-exposed cells increased endogenous antioxidant enzymes, including superoxide dismutase-2 and heme oxygenase-1, and ameliorated significantly both the oxidative stress damage and the mitochondrial alterations, that are known to be involved in aging and aging related diseases. In conclusion, melatonin had important anti-oxidant and anti-aging effects at the level of skeletal muscle in vitro.

description: The aging process involves different organs, including the musculoskeletal system. Age-related modifications affecting the tendon such as reduced cell proliferation and decreased glycosaminoglycan and proteoglycan content were previously described, but data are incomplete and discordant. Therefore, aim of our study was to characterize the effect of aging on tendons, with particular attention to collagen turnover. For this purpose, tendons and cultured tenocytes were obtained by healthy young (age <65 years) and aging subjects (≥65 years), and analyzed by morphological and molecular methods. Our data show that aging tenocytes have a reduced proliferation rate. Haematoxylin and eosin, Sirius red and Alcian blue staining, respectively, revealed that tendon structure is maintained, and that collagen and proteoglycan content is similar in young and aging tendons. However, decreased lysyl hydroxylase 2b gene expression was observed in aging tenocytes, suggesting that differences in collagen maturation could be responsible for a decreased ability to resist mechanical loading. By fluorescence microscopy, actin cytoskeleton modifications such as fewer and shorter stress fibers were observed in some aging tenocytes, consistent with a decreased ability to form focal adhesions and, therefore, a reduced migration potential. Intermediate filaments and microtubules were not modified by aging. Considered as a whole, our results suggest that the structure of aged tendons is preserved, but the biomechanical properties could be impaired by reduced collagen cross-linking. Moreover, modifications of actin filaments could affect the mechanotransduction system allowing tenocytes to adapt their ability for extracellular matrix remodeling in response to mechanical loading. Therefore, aged tendons could be likely more prone to develop tendinopathies.

description: We consider the problem of data exchange by a group of closely-located wireless nodes. In this problem each node holds a set of packets and needs to obtain all the packets held by other nodes. Each of the nodes can broadcast the packets in its possession (or a combination thereof) via a noiseless broadcast channel of capacity one packet per channel use. The goal is to minimize the total number of transmissions needed to satisfy the demands of all the nodes, assuming that they can cooperate with each other and are fully aware of the packet sets available to other nodes. This problem arises in several practical settings, such as peer-to-peer systems and wireless data broadcast. In this paper, we establish upper and lower bounds on the optimal number of transmissions and present an efficient algorithm with provable performance guarantees. The effectiveness of our algorithms is established through numerical simulations.

description: The progress of image processing during recent years allows the measurement of pedestrian characteristics on a "microscopic" scale with low costs. However, density and flow are concepts of fluid mechanics defined for the limit of infinitely many particles. Standard methods of measuring these quantities locally (e.g. counting heads within a rectangle) suffer from large data scatter. The remedy of averaging over large spaces or long times reduces the possible resolution and inhibits the gain obtained by the new technologies. In this contribution we introduce a concept for measuring microscopic characteristics on the basis of pedestrian trajectories. Assigning a personal space to every pedestrian via a Voronoi diagram reduces the density scatter. Similarly, calculating direction and speed from position differences between times with identical phases of movement gives low-scatter sequences for speed and direction. Closing we discuss the methods to obtain reliable values for derived quantities and new possibilities of in depth analysis of experiments. The resolution obtained indicates the limits of stationary state theory.

description: We study CMV matrices by focusing on their right-limit sets. We prove a CMV version of a recent result of Remling dealing with the implications of the existence of absolutely continuous spectrum, and we study some of its consequences. We further demonstrate the usefulness of right limits in the study of weak asymptotic convergence of spectral measures and ratio asymptotics for orthogonal polynomials by extending and refining earlier results of Khrushchev. To demonstrate the analogy with the Jacobi case, we recover corresponding previous results of Simon using the same approach.

description: An approach is proposed which allows to self-consistently calculate the structural and thermodynamic properties of highly charged aqueous colloidal suspensions. The method is based on the renormalized Jellium model with the background charge distribution related to the colloid-colloid correlation function. The theory is used to calculate the correlation functions and the effective colloidal charges for suspension containing additional monovalent electrolyte. The predictions of the theory are in excellent agreement with the Monte Carlo simulations.

The determination of impurity concentrations in silicon
Creators: name: Jones, David John Gunning
Publisher: name: University of British Columbia
Year: 2011

description: Due to the small concentration of impurities normally present in semiconductors these impurity concentrations cannot' be measured by ordinary chemical analysis. Electrical methods are the common way by which semiconductor impurity concentrations are measured. The specific problem investigated was to determine the concentration Nd of donors and the concentration Na of acceptors at various points in a crystal of silicon. A description of the crystal structure and the energy band scheme of silicon is given. The density of states in the conduction and valence bands is calculated. The population of the conduction and valence bands by electrons and holes as a function of impurity concentration and temperature is derived. A method is given from which the values of Nd and Na may be found from Hall constant measurements at liquid nitrogen and room temperatures. The experimental apparatus used includes a magnet, cryostat, sample holder, and Hall measuring circuit. The results obtained from the measurements are in agreement with those expected from the available knowledge of the method of crystal growth.
