description: Starting from the Shannon channel capacity, we propose an IR-UWB channel capacity based on the delay spread for multipath time variant channels. This IR-UWB channel capacity is obtained from the no ISI (Inter Symbol Interference) assumption and for binary modulations. The impact of the kind of implementation is considered on the IR-UWB channel capacity. This study is lead for mixed and mostly digital implementation. The key parameters and theirs impacts on the channel capacity are exposed in each case: the data converters for mostly digital implementations and the pulse generator capabilities for mixed implementations. Finally, these two implementations are compared from a data rate point of view. Their behaviors regarding an increase of the operating frequency are also studied.

description: For the enhanced understanding of fundamental cancer biology and improving molecular diagnostics and therapeutics, the role of the microenvironment during the initiation and progression of carcinogenesis is thought to be of critical importance (1, 2). The aim of this study was to establish an in vitro model based on a co-culture of healthy human fibroblasts (HFs) and human osteosarcoma cells (MG-63s) to simulate the microenvironment including tumor and healthy cells. The HFs and MG-63s were in vitro co-cultured for a period of time ranging from 24h to 7 days. Cell morphology and organization were studied by phase contrast microscopy while the expression of Human Cartilage Glycoprotein 39 (YKL-40), Vascular Endothelial Growth Factor (VEGF), Matrix Metalloprotease 1 (MMP1) and IL1 alpha was investigated by Real Time PCR and Western Blotting. To better correlate the role of YKL-40, VEGF, MMP1 and IL1 alpha, siRNA knockdown of YKL-40 in MG-63 cells was performed, and changes in protein expression in the co-cultures were analyzed. Results showed a characteristic disposition of tumor and healthy co-cultured cells in columns which are not visible in tumor and healthy cells grown singularly. The expression of YKL-40, VEGF and MMP1 significantly changed in co-cultured cells compared to HFs and MG-63s separately cultured. siRNA knockdown of YKL-40 was responsible of a down-regulation of VEGF expression on HFs, and an increase of IL1 alpha expression in MG-63s. These results suggest that the tumor microenvironment has an influence on the protein expression of the healthy surrounding tissues and the process of tumorigenicity.

description: Asthenozoospermia may result from different biochemical and functional defects. In particular, it has been demonstrated that reactive oxygen species (ROS) have a role in its pathogenesis. These reactive molecules may mediate the biological effects of cytokines, acting as intracellular signals. Human sperm cells are able to produce biologically active interleukin-1β (IL-1β), which stimulates cyclooxygenase-2 (COX-2) in various cells and tissues, including human reproductive tissues, even if its effects on male reproductive biology are largely unknown. COX-2 is the inducible isoform of the key enzyme in the biosynthesis of prostaglandins, and it could be also induced by hypoxia-inducible factor -1α (HIF -1α), which regulates many genes important for oxygen homeostasis. It has been recently proposed an involvement of COX-2 in male fertility disorders. In this scenario, our aim was to evaluate sperm parameters, as well as the expression of IL-1β, COX-2, and HIF -1α in spermatozoa isolated from normospermic fertile donors and asthenozoospermic infertile patients, by means of immunohistochemical analysis and enzyme-linked immunosorbent assay (ELISA). Sperm cells obtained from the asthenozoospermic group showed a higher expression of IL-1β, COX-2, and HIF-1α, compared with those from normospermic fertile subjects. Our results can lead us to speculate that the increased expression of these substances may influence the kinetic characteristics of spermatozoa. Nevertheless, further studies are in progress in order to assess whether these bioactive mediators may represent targets for future therapeutic strategies.

On the time modulation of the K-shell electron capture decay rates of H-like heavy ions at GSI experiments

description: According to experimental data at GSI, the rates of the number of daughter ions, produced by the nuclear K-shell electron capture (EC) decays of the H-like heavy ions with one electron in the K-shell, such as 142Pr58+, 142Pm60+ and 122I52+, are modulated in time with periods T_(EC)of the order of a few seconds, obeying an A-scaling T_(EC)= A/20 s, where A is the mass number of the mother nuclei, and with amplitudes a^(EC)_d ~ 0.21. We show that these data can be explained in terms of the interference of two massive neutrino mass-eigenstates. The appearance of the interference term is due to overlap of massive neutrino mass-eigenstate energies and of the wave functions of the daughter ions in two-body decay channels, caused by the energy and momentum uncertainties introduced by time differential detection of the daughter ions in GSI experiments.

description: Since ancient times, silver has been extensively used to control infections. Silver based medical products have been proved to be effective in retarding and preventing bacterial infections (Chen et al., 2007). In order to prevent silver nanoparticles aggregation a lactose-modified chitosan was shown to be effective in stabilizing colloidal solutions of silver nanoparticles: “Chitlac-nAg” (Travan et al., 2009). Silver ions and nanoparticle are capable to destroy the bacterial cell wall by reacting with sulfhydryl groups on membrane proteins (Kruszewski et al., 2003). Since the cells are capable of internalizing nanoparticles there is the risk of a massive uptake by eukaryotic cells, which eventually leads to their death through oxidative DNA damage (Li et al. 2013) In the present work we investigated the effects of Chitlac-nAg on primary human gingival fibroblast (HGFs) co-cultured with Streptococcus mitis in the presence of saliva. HGFs were obtained from fragments of healty marginal gingival tissue, co-cultured with the clinical strain of S. mitis and treated for 24-48h with Chitlac or Chitlac-nAg. Cytotoxicity evaluated by LDH assay showed an increment in LDH release in co-culture in the presence of Chitlac n-Ag and saliva. Oxidative stress detected by means of Reactive Oxygen Species formation highlighted an early ROS presence in samples with Chitlac-nAg and saliva, but this value was similar to control after 48h; apoptotic and necrotic cells were detected by means of Annexin V/PI showing an increase in cell death in HGFs treated with Ag and saliva after 24h, and returned to basal levels after 48h; the uptake of nanoparticles by cells was determined by optical and electronic microscopy revealing the Ag uptake in vesicles. The presence of lysosomes and autophagosomes was verified by Lysotracker and by LC3 respectively. In vitro results showed that in our co-culture model, which mimics the microenvironment of the oral cavity, chitlac n-Ag does not exert cytotoxic effect towards HGFs that are able to execute a homeostasis mechanism through autophagy promoting cell survival.

description: In the marrow, macrophages form a morphological unit, the erythroblast island and in culture release factors still to be marked that affect the growth of the erythroblasts(Ery).When blood CD34pos are stimulated with dexamethasone(Dex) and growth factors in human erythroid massive amplification(HEMA)cultures, large numbers of Ery are generated which remain immature and proliferate for 10-17 days. Dex withdrawl and erythropoietin(EPO)exposure induce Ery to activate the maturation program within 24-48 h.At day 13-14 of HEMA. The role of macrophages in HEMA has not been investigated. Live contrast-phase microscopy(10x magnify.;timelapses: 1 frame/30”recorded for 8-10h)was used to visualize interactions between Ery and macrophages in day 13-14 HEMA with or without Dex and in cultures in which day 13-14 progeny were exposed to EPO alone. Macrophages and Ery at different stages of maturation were recognized on the basis of size, chromatin condensation state, motility and frequency using data previously obtained by FACS as comparison. Day14 without Dex: Ery at all maturation stages were observed moving in a coordinate fashion but with frequent changes in directions. Ery formed few, loose and unstable aggregates. Macrophages were rare and moved independently from Ery.Day14 with Dex: Ery moved synchronously toward each other forming large and stable aggregates. Macrophages were “fat”, highly motile and extended short protrusions which established transient contacts with hundreds/thousands of Ery over 1 h. Contacts involved both isolated Ery (interactions, “loose”)or clusters of Ery at all maturation stages(interactions “tight”). In the first 45’of observation,~45% of the interactions were loose,~23% were a combination of loose and tight and~35%were tight. By 1-2h,25% were loose,50% were loose and tight and 25% were tight. Cytokinesis involved single and double proEry. The process lasted 5’ and was not associated with macrophages. Dex withdrawal and EPO exposure induced noticeable changes.By15’,macrophages became greatly motile engaging in fewer “loose” interactions( 5-9%)and in more “tight” interactions. By 60’,86%of the interactions were “tight” and involved preferentially clusters of mature Ery (>80%).Mega-aggregates including 2-6 macrophage-Ery clusters each were also observed.

description: The macroscopic mechanical properties of densely packed coagulated colloidal particle gels strongly depend on the local arrangement of the powder particles on length scales of a few particle diameters. Heterogeneous microstructures exhibit up to one order of magnitude higher elastic properties and yield strengths than their homogeneous counterparts. The microstructures of these gels are analyzed by the straight path method quantifying quasi-linear particle arrangements of particles. They show similar characteristics than force chains bearing the mechanical load in granular material. Applying this concept to gels revealed that heterogeneous colloidal microstructures show a significantly higher straight paths density and exhibit longer straight paths than their homogeneous counterparts.

Secondo Anshul Saini e Dejan Stojkovic, l'informazione contenuta in un buco nero potrebbe non essere persa per sempre. I risultati del loro studio implicano che per un osservatore che si trovi al di fuori dell’orizzonte degli eventi è ancora possibile recuperare l’informazione e rappresentano un passo significativo verso la soluzione dell'ormai famoso “paradosso dell’informazione dei buchi neri”
Bulk-handling compared with the use of field boxes with reference to the post-harvest physiology of apples
Creators: name: Combret, Robert Jules Louis
Publisher: name: University of British Columbia
Year: 2012

description: Yellow Newtown apples handled in bulk in large twenty-five bushel bins showed less bruising than those handled in standard one-bushel field boxes. Most of the bruising took place during the dumping on to the grader operation rather than at picking time. The mechanical dumping of the large bins did not cause as severe bruising as did the manual dumping of the field boxes. The apples bulk handled and stored in the large bins proceeded at a lower respiration rate, maintained a higher sugar level, kept firmer, shrivelled less and were freer from storage physiological disorders than those similarly handled and stored in the standard field boxes. Storing apples in polyethylene bags kept the fruit in a similar physiological condition to that of apples stored in bulk bins. Evidence presented suggests that storage in large bulk bins effects apples in a beneficial manner similarly to the use of polyethylene box liners and to controlled atmosphere storage. It was concluded that bulk-handling is beneficial to the post - harvest physiology of Yellow Newtown apples. It improves their storage qualities, preserves a better appearance and so increases their marketability in comparison to apples which are handled in standard field boxes.

description: We use the non-equilibrium Green function (NEGF) method in the ballistic limit to provide a quantitative description of the conductance of graphene pn junctions - an important building block for graphene electronics devices. In this paper, recent experiments on graphene junctions are explained by a ballistic transport model, but only if the finite junction transition width, Dw, is accounted for. In particular, the experimentally observed anamolous increase in the resistance asymmetry between nn and np junctions under low source/drain charge density conditions is also quantitatively captured by our model. In light of the requirement for sharp junctions in applications such as electron focusing, we also examine the pn junction conductance in the regime where Dw is small and find that wavefunction mismatch (so-called pseudo-spin) plays a major role in sharp pn junctions.

description: Single crystals of the Ni-doped FeAs-based superconductor SrFe2-xNixAs2 were grown using a self-flux solution method and characterized via x-ray measurements and low temperature transport, magnetization, and specific heat studies. A doping phase diagram has been established where the antiferromagnetic order associated with the magnetostructural transition of the parent compound SrFe2As2 is gradually suppressed with increasing Ni concentration, giving way to bulk-phase superconductivity with a maximum transition temperature of 9.8 K. The superconducting phase exists through a finite range of Ni concentrations centered at x=0.15, with full diamagnetic screening observed over a narrow range of x coinciding with a sharpening of the superconducting transition and an absence of magnetic order. An enhancement of bulk superconducting transition temperatures of up to 20% was found to occur upon high-temperature annealing of samples.

description: Throughout fetal life, striatal neurons originated in the ganglionic eminence from a population of dividing stem cells. Little is known about the molecular mechanisms that regulate the activation, self-renewal and differentiation of striatal neuronal precursors. In order to identify the regulatory mechanisms controlling striatal cell neurogenesis and differentiation, we have recently isolated and propagated in vitro primary cell cultures from the human fetal striatal primordium (1). These cells express both neuronal and striatal properties, and are responsive to BDNF and FGF2. In this study, we found that human striatal precursor (HSP) cells are a mixed population mainly constituted of neuronal-restricted progenitors and striatal neurons (DARPP32-, GAD1-expressing cells) and neural/stem cells, which under specific in vitro differentiating conditions not only generate neurons, astrocytes and oligodendrocytes, but also possess the ability of osteogenic differentiation. We also observed that BDNF and FGF2 exert different effects on HSP depending on the differentiation state of these cells. In fact, both neurotrophins promote cell proliferation, migration and the expression of neural stem/progenitor markers in undifferentiated HSP cells, while they stimulate neuritogenesis in the neuronal differentiated component as demonstrated after specific neuronal induction. We have previously reported that striatal primordium from human fetus was able to grow into the brain of Huntington’s disease (HD) patients and that this process was associated with metabolic change and some clinical benefit (2,3). Our results add new insight into the developmental processes of human fetal striatal grafts in HD and, in addition, have implications for cell based transplantation approaches in the CNS.

Subjects: Pancreatic Islet Transplantation; Mesenchymal Stem Cells; Type-1 Diabetes.

description: The transplantation of pancreatic islets is an innovative and intriguing therapeutic option for the long term treatment of type-1 diabetes (Remuzzi et al., 2009). Unfortunately, their clinical feasibility is limited by the great number of islets necessary to achieve glycaemic control and their short survival. A possible means to improve the performance of this technique can be represented by Mesenchymal Stem Cells (MSCs), adult stem cells alrady known to support the survival of different cellular populations (Scuteri et al., 2014). In this work the ability of Mesenchymal Stem Cells (MSCs) to improve the feasibility of this approach was verified into an in vivo model represented by Streptozotocin-induced diabetic rats. We compared 5 different groups (8 rats/group): a) healthy controls; b) Diabetic rats; c) Diabetic rats transplanted with pancreatic islets (3000); d) Diabetic rats cotransplanted with pancreatic islets (2000) and MSCs (106); Diabetic rats treated with MSCs (106). Transplantations were performed after the assessment of neuropathic signs, represented by a decreased Nerve Conduction Velocity (NCV) and an impairment of nociceptive thermal and mechanical thresholds. The same parameters were evaluated two months after the transplantation. Diabetic rats transplanted only with pancreatic islets, or co-transplanted with MSCs and a suboptimal number of pancreatic islets, showed a significant glycaemia value reduction, an improvement of thermal and mechanical sensitivity, and an improvement of NCV with respect to diabetic-untreated rats. No differences were observed between diabetic rats and diabetic rats treated with only MSCs. In conclusion, we demonstrated that co-transplantation with MSCs reduces the number of pancreatic islets needed to reach glycaemic control, and induces the regression of painful neuropathy signs, thus ameliorating diabetes complications management.

Subjects: Ovarian cancer; anti-HIV drugs.

description: In Italy, every year new cases of ovarian cancer are approximately 5,000, 3,000 are the deaths; this means that 1 woman out of 70 is destined to fall ill and 1 out of 100 to die for this malignancy. Drugs of choice for the treatment of HIV, able to determine a decrease in viral load, have proven to be effective also against neoplasms (Kaposi sarcoma [1] and non-Hodgkin lymphomas [2]) frequent in subjects with acquired immunodeficiency syndrome (AIDS) that thanks to these drugs, are now in evident decline. Our research aims to highlight and characterize, therefore, the effects of anti-HIV drug therapy on Skov3 cells (ovarian adenocarcinoma), hoping for a possible role in the control of ovarian cancer, which is not among the cancers specific of HIV infection. Skov3 cells were cultured and then treated with the chosen drugs: abacavir, tenofovir, efavirenz, etravirine (reverse transcriptase inhibitors) and darunavir (protease inhibitor). At the cytofluorimetric analysis treated cells showed the following results: Abacavir (NRTIs) and Darunavir (PI) do not show any particular modulation of the cell cycle. Tenofovir (NtRTIs) showed an increase amount of cells in the G0/G1 phase of the cell cycle progression. Instead Efavirenz (NNRTIs) and Etravirine (NNRTIs) showed a block in the G0/G1 phase. Between the two drugs of the same class (NNRTIs) the block activity of Etravirine in G0/G1 of cell cycle is higher as compared to Efavirenz; at the same time, Etravirine determines the differentiation of Skov3. DAPI staining has allowed the identification of DNA damage in cells treated with efavirenz and an increased condensation of DNA in cells treated with etravirine. After treatment with tenofovir, efavirenz and etravirine, in Skov3 cells, we observed through immonoblotting: reduction of cyclin D1 concentration, hypophosphorylation of Rb and increase of p21 concentration. Only Skov3cells treated with etravirine showed high levels of E-cadherin expression. Reverse transcriptase, based on these data, can be considered an epigenetic regulator of cell proliferation and differentiation and may represent a new target in cancer therapy. Furthermore, we believe that the drugs used, modulating cell proliferation and differentiation, may represent a new frontier in the development of a therapeutic approach to ovarian cancer.

description: Following the discovery of burials in Monte Carru – Alghero (Sardinia) during the preliminary investigation to the creation of a housing development detected a Imperial Roman necropolis (I-III century A.D.). A total of 350 tombs – 150 burials and 200 cremations. This necropolis is supposed belongs to the undiscovered village of Carbia mantioned by the sources. Up to now have been analyzed 11 burials. The samples are clened by water and glued with PVA glue. Subsequently has been performed the anthropological study following the mains anthropological methods ( Meindel & Lovejoy, 1985; Iscan 1985; Ubelaker 1989; Trotter & Gleser 1952) and some new method (Vance – Steyn- L’Abbé 2011; Chibba e Bidmos, 2007; Bidmos, 2006). Every burial has been sampled for metagenomic and DNA study. Up to now have been analyzed 10 adults and 1 subadult. The adults are in 60% female and just 1 is undeterminate; the age of death is between 25 and 45 years; it was no possible to determinate the height . There were no obvius pathology but this can be for the extreme deterioration of bones. There are dental wear widespread mainly on premolars and first molar ; caries is present mainly on molars and dental calculus mainly on incisors. The analyzed population of Monte Carru in Roman Age shows a good state of health, no obvious pathologies and a enamel wear. More analysies are neccesary to better understand the site.

description: This study is aimed to further characterize on a neurochemical, histological and morphometric ground the human Locus K, a newly identified region in the human nucleus cuneatus that shares neurochemical features with protopathic second order sensory nuclei (Del Fiacco et al., 2013; Serra et al., 2013). Human brainstem sections were observed by means of ABC immunohistochemistry for calcitonin gene-related peptide (CGRP), substance P (SP) and transient receptor potential vanilloid type-1 receptor (TRPV1), Kluver-Barrera, Black Gold kit II and Nissl staining followed by computerized analysis of cell size and density. As for CGRP and SP, at both pre- and postnatal age, immunoreactivity to TRPV1 occurs in Locus K with a distribution alike that present in the spinal trigeminal nucleus, caudal part. Morphometric analysis shows that, in adult tissue, the mean diameter and density of Nissl stained neurons in the Locus K are consistent with those of the caudal spinal trigeminal and solitary nuclei, and different from those in the gracile, cuneate and external cuneate nuclei. Kluver-Barrera and Black Gold kit II staining shows that myelinated fibres, abundant in the main cuneate, gracile and trigeminal magnocellular nuclei, are scarce in both the Locus K and trigeminal substantia gelatinosa. Immunohistochemical and cyto- and myeloarchitectural analysis uphold the parallel neurochemical and structural arrangement for Locus K and protopathic nuclei in the human medulla oblongata, and support the concept that Locus K represents a special component of the human dorsal column nuclei.

description: Investigations into ophiolite from California demonstrated that these ultramafic rocks formed within the mantle wedge of a subduction zone. Fore-arc locales are dominated by highly refractory peridotite, formed by hydrous-fractional partial melting that began in the garnet stability field and ended in the spinel stability field. These ophiolites also displayed enriched fluid-mobile element concentrations. Based on melt models, these elements should have extremely low concentrations, yet all pyroxenes display enriched compositions. A new algorithm was derived to model this fluid enrichment process, which represents the total addition of material to the mantle wedge source region and can be applied to any refractory mantle peridotite that has been modified by melt extraction and/or metasomatism. Investigations into the interaction of a mantle plume with continental lithosphere demonstrated that Yellowstone-Snake River Plain olivine tholeiites are compatible with genesis from a deep-seated mantle plume and were modeled via mixing of three components. The variable age, thickness, and composition of North American lithosphere guide this process. Drill core near Twin Falls, ID was examined to assess (1) the chemical evolution of olivine tholeiite, (2) how basalt evolves in continental settings, and (3) the dominant fractionation process, e.g., fractional crystallization, Raleigh fractional crystallization, or assimilation fractional crystallization.

description: For physicians, the human body is the focus of investigation and intervention on a daily basis. It follows that the study of anatomy will continue to be essential to safe medical practice [1]. Anatomical education represents the cultural path that includes the best coexistence of old techniques, and avant-garde. Thus teachers forming future physicians are imposed to find new strategies for the acquisition of adequate professional competences [2]. The gross anatomy course attended by medical students was integrated by ultrasound training. Students were trained either in palpating and recognizing surface body-landmarks, or in the detection of different viscera. Their abilities were then evaluated. For three academic years (since 2009-10 to 2011-12), all the 262 students enrolled in the first year of Medicine and Surgery degree (“San Paolo” Hospital, Università degli Studi di Milano, Italy) participated. Of them, 16 volunteered in 2009-10, and 17 in each of the next two years, to preliminarily attend ultrasound training that their fellows would attend later. After this preliminary training, volunteers tutored their course fellows as peer tutors. All participants were either models or users. Each training presented three modules: 1) information about ultrasound scanning; 2) musculoskeletal system, major arterial and venous vessels, major nervous trunks, thyroid gland; 3) most thoracic, abdominal and pelvic viscera. Modules 2 and 3 were attended by small groups (6 students, assisted by 2 peer tutors). In module 2, topographical anatomy and subsequent recognition and palpation of surface bodylandmarks were also taught. The study of musculoskeletal system, major vessels and nerve trunks, and thyroid gland was supported by a multi-frequency probe equipped ultrasound machine. Thoracic, abdominal, and pelvic viscera were explored by a new generation pocket-sized ultrasound machine. Acquired skills were verified. The levels of expertise obtained by peer tutors and students were generally satisfactory. Students understood the importance of operative knowledge in human anatomical context. Anatomists found a valid method to consolidate the professionalizing quality of the topic.
