Germ Line p53 Mutations in a Familial Syndrome of Breast Cancer, Sarcomas, and Other Neoplasms (1990)

Familial cancer syndromes have helped to define the role of tumor suppressor genes in the development of cancer. The dominantly inherited Li-Fraumeni syndrome (LFS) is of particular interest because of the diversity of childhood and adult tumors that occur in affected individuals. The rarity and high mortality of LFS precluded formal linkage analysis. The alternative approach was to select the most plausible candidate gene. The tumor suppressor gene, p53, was studied because of previous indications that this gene is inactivated in the sporadic (nonfamilial) forms of most cancers that are associated with LFS. Germ line p53 mutations have been detected in all five LFS families analyzed. These mutations do not produce amounts of mutant p53 protein expected to exert a trans-dominant loss of function effect on wild-type p53 protein. The frequency of germ line p53 mutations can now be examined in additional families with LFS, and in other cancer patients and families with clinical features that might be attributed to the mutation.
Promising new treatments for neovascular age-related macular degeneration (2006)

Angiogenesis, the growth of new blood vessels from existing blood vessels, is responsible for vision loss in a variety of ophthalmic diseases. In neovascular age-related macular degeneration (AMD), the leading cause for legal blindness in many industrialised countries, abnormal blood vessels grow in the macula and cause blindness. There are a number of factors important in the angiogenic cascade but VEGF-A has been implicated in recent years as the major factor responsible for neovascular and exudative diseases of the eye. Numerous antiangiogenic drugs are in development but anti-VEGF drugs have shown great promise in treating neovascular AMD and other ocular diseases, and many of these drugs have been adopted from oncology where antiangiogenic therapy is gaining wide acceptance. For the first time in neovascular AMD, anti-VEGF drugs have brought the hope of vision improvement to a significant proportion of patients. This review provides an overview on angiogenic mechanisms, potential antiangiogenic treatment strategies and different antiangiogenic drugs with special focus on neovascular AMD.
Association between IL-6 and CD40 signaling. IL-6 induces phosphorylation of CD40 receptors. (1990)

CD40 mAb at subsaturating doses inhibit the growth of transformants of the M12 murine cell line expressing intact full length CD40 molecules (M12/CD40+ cells) but do not inhibit the growth of two M12 transformants expressing either a mutant CD40 cDNA missing most of the cytoplasmic tail (CD40/tailless) or a mutant cDNA with a substitution at residue 234 (CD40/234A, Ala for Thr). Using these transformants, we tested a panel of cytokines for the ability to mimic CD40 mAb. rIL-6 behaved like CD40 mAb and inhibited the growth of M12/CD40+ cells but not of CD40/tailless or CD40/234A mutants. The effect of IL-6 on M12/CD40+ cells not only required intact CD40 including threonine 234 but also was specific because IL-6 mAb blocked the inhibitory activity. The M12/CD40+ cells responsive to IL-6 expressed greater than 300,000 CD40 molecules/cells but, like M12/CD40-controls, expressed only small numbers (less than 50/cell) of high affinity IL-6R, indicating that CD40 is not a receptor for IL-6. Nevertheless, IL-6 utilizes intact CD40 efficiently when it signals these cells: treatment of M12/CD40+ cells with IL-6 induced increased phosphorylation of CD40. Conversely, triggering CD40 on M12/CD40+ cells leads to IL-6 production. Similar effects were evident in human CD40+ B cells: IL-6 increased the phosphorylation of CD40 in the IL-6-responsive cell line, CESS, and CD40 mAb induced IL-6 production in activated human B cells. Thus, CD40 may function to receive and regulate IL-6-dependent signals in B cells.
Diabetes and Glucose Tolerance as Risk Factors for Cardiovascular Disease: The Framingham Study (1979)

This report examines prospectively, in the Framingham cohort, the relation of diabetes and impaired glucose tolerance to each of the cardiovascular sequelae, taking into account age, sex, and associated cardiovascular risk factors. The incidence of cardiovascular disease, as well as the levels of cardiovascular risk factors, were found to be higher in diabetic than in nondiabetic men and women. The relative impact of diabetes on coronary heart disease, peripheral vascular disease, or stroke incidence was the same in men and women, but for cardiovascular mortality and cardiac failure the impact is greater for women. Present evidence suggests that alleviation of associated cardiovascular risk factors is the most promising course in reducing cardiovascular sequelae in diabetic patients.
Interstitial Collagenase and the ED-B Oncofetal Domain of Fibronectin Are Markers of Angiogenesis in Human Skin Tumors (1998)

Collagenase-1 (C1) is the predominant matrix metalloproteinase present in newly formed microvessels and serves as a marker of neovascularization. The expression of the oncofetal fragment of fibronectin (Fn-f) was found to be increased during angiogenesis. In the present study, we investigated the relationship between the expression of collagenase-1 and the oncofetal fragment of fibronectin in newly formed microvessels as markers of tumor angiogenesis. In aggressive skin tumors (i.e., morpheaform and recurrent basal cell carcinomas) and squamous cell carcinomas, neovascularization was associated with a marked increase in the number of C1-positive and Fn-f-positive microvessels. At the beginning of elongation, microvessels begin to produce C1 but lose their ability to express type IV collagen and FVIII-related antigen. Later, this endothelium produces both Fn-f and C1. As maturation of microvessels occurs, C1-containing endothelium fails to express Fn-f but begins to produce a type IV collagen-containing basement membrane and FVIII-related antigen. These studies show that there is a selective expression of both Fn-f and collagenase by immature endothelial cells. C1 production begins at early stages of blood vessel formation and continues throughout angiogenesis. In contrast, Fn-f expression is limited to later stages of vasculogenesis, indicating that these proteins are reliable markers of angiogenesis.
c-Met is essential for wound healing in the skin (2007)

Wound healing of the skin is a crucial regenerative process in adult mammals. We examined wound healing in conditional mutant mice, in which the c-Met gene that encodes the receptor of hepatocyte growth factor/scatter factor was mutated in the epidermis by cre recombinase. c-Met-deficient keratinocytes were unable to contribute to the reepithelialization of skin wounds. In conditional c-Met mutant mice, wound closure was slightly attenuated, but occurred exclusively by a few (5%) keratinocytes that had escaped recombination. This demonstrates that the wound process selected and amplified residual cells that express a functional c-Met receptor. We also cultured primary keratinocytes from the skin of conditional c-Met mutant mice and examined them in scratch wound assays. Again, closure of scratch wounds occurred by the few remaining c-Met-positive cells. Our data show that c-Met signaling not only controls cell growth and migration during embryogenesis but is also essential for the generation of the hyperproliferative epithelium in skin wounds, and thus for a fundamental regenerative process in the adult.
Molecular dynamics studying on welding behavior in thermosetting polymers due to bond exchange reactions (2016)

The surfaces of covalent adaptable network polymers can be welded together through bond exchange reactions occurring at the interface, resulting in new bonds crossing the interface and connecting the two materials.
Adsorption Equilibria of Arabinose, Fructose, Galactose, Glucose, Mannose, Rhamnose, Sucrose, and Xylose on Ion-Exchange Resins (2010)

Adsorption equilibria of arabinose, fructose, galactose, glucose, mannose, rhamnose, sucrose, and xylose were evaluated on four different types of ion-exchange resins. The resins were strong acid cation (SAC), strong base anion (SBA), weak base anion (WBA), and weak acid cation (WAC) in typical ion forms (Na+ and SO42−) and had similar cross-linking degrees (divinylbenzene content between (5 and 6) %) and bead sizes. The single-component isotherms of the sugars were determined at 65 °C by a static method. The equilibrium data were described with linear isotherms over the concentration range between (0 and 350) g·L−1. The decomposition of sugars was analyzed by high-performance liquid chromatography (HPLC) measurements. The use of the WAC exchange resin is especially restricted due to the decomposition of sugars under the typical operating conditions of the resin. The WBA exchange resin showed high selectivity for xylose and arabinose. The SBA exchange resin also demonstrated good selectivity for xylose and rhamnose, which implies that these could be separated from biomass hydrolysates with the SBA exchange resin.
Vehicle-to-Vehicle IEEE 802.11p performance measurements at urban intersections (2012)

During the last few years, vehicle-to-vehicle (V2V) wireless communication has become a key objective for enabling future cooperative safety applications, such as intersection collision warning. In this paper, we present the results of a 5.9 GHz V2V performance measurement campaign at four different urban intersections under NLOS conditions using commercial off-the-shelf wireless interface cards which meet the 802.11p and ITS-G5 specifications. Particularly, we quantify the packet delivery ratio (PDR) and received signal strength indication (RSSI) levels associated with different scenario conditions with respect to vehicle positioning, intersection geometry and traffic density. We determine reliable communication ranges which constitute an important metric for V2V collision avoidance applications.

The Ste5p scaffold (2001)

An emerging theme of mitogen-activated protein kinase (MAPK) cascades is that they form molecular assemblies within cells; the spatial organization of which is provided by scaffold proteins. Yeast Ste5p was the first MAPK cascade scaffold to be described. Early work demonstrated that Ste5p selectively tethers the MAPKKK, MAPKK and MAPK of the yeast mating pathway and is essential for efficient activation of the MAPK by the pheromone stimulus. Recent work indicates that Ste5p is not a passive scaffold but plays a direct role in the activation of the MAPKKK by a heterotrimeric G protein and PAK-type kinase. This activation event requires the formation of an active Ste5p oligomer and proper recruitment of Ste5p to a Gbetagamma dimer at the submembrane of the cell cortex, which suggests that Ste5p forms a stable Ste5p signalosome linked to a G protein. Additional studies underscore the importance of regulated localization of Ste5p to the plasma membrane and have revealed nuclear shuttling as a regulatory device that controls the access of Ste5p to the plasma membrane. A model that links Ste5p oligomerization with stable membrane recruitment is presented. In this model, pathway activation is coordinated with the conversion of a less active closed form of Ste5 containing a protected RING-H2 domain into an active Ste5p dimer that can bind to Gbetagamma and form a multimeric scaffold lattice upon which the MAPK cascade can assemble.
Efficient multiparty quantum-secret-sharing schemes (2004)

In this work, we generalize the quantum-secret-sharing scheme of Hillery, Bu\ifmmode \check{z}\else \v{z}\fi{}ek, and Berthiaume [Phys. Rev. A 59, 1829 (1999)] into arbitrary multiparties. Explicit expressions for the shared secret bit is given. It is shown that in the Hillery-Bu\ifmmode \check{z}\else \v{z}\fi{}ek-Berthiaume quantum-secret-sharing scheme the secret information is shared in the parity of binary strings formed by the measured outcomes of the participants. In addition, we have increased the efficiency of the quantum-secret-sharing scheme by generalizing two techniques from quantum key distribution. The favored-measuring-basis quantum-secret-sharing scheme is developed from the Lo-Chau-Ardehali technique [H. K. Lo, H. F. Chau, and M. Ardehali, e-print quant-ph∕0011056] where all the participants choose their measuring-basis asymmetrically, and the measuring-basis-encrypted quantum-secret-sharing scheme is developed from the Hwang-Koh-Han technique [W. Y. Hwang, I. G. Koh, and Y. D. Han, Phys. Lett. A 244, 489 (1998)] where all participants choose their measuring basis according to a control key. Both schemes are asymptotically $100%$ in efficiency, hence nearly all the Greenberger-Horne-Zeilinger states in a quantum-secret-sharing process are used to generate shared secret information.
Is an “à la carte” combination interferon alfa-2b plus ribavirin regimen possible for the first line treatment in patients with chronic hepatitis C? (2000)

The combination of IFN-R is better as first line treatment than IFN monotherapy. For patients who are PCR negative after 24 weeks of treatment, genotyping and baseline viral load, fibrosis stage, gender, and age are useful predictive factors in determining whether to continue an additional 24 weeks of treatment.
Absorbent Polymers from Starch and Flour Through Graft Polymerization of Acrylonitrile and Comonomer Mixtures (1978)

Abstract Polyacrylonitrile (PAN)‐containing graft copolymers of corn starch were prepared from monomer mixtures and then saponified, and dried. Incorporation of selected comonomers lead to shorter saponification times and higher yields of adsorbent products. Substitution of flour for starch gave products which had a higher absorbency than saponified starch‐ g ‐PAN.
Physical specifications of clinical proton beams from a synchrotron (1996)

Tumor treatment with charged particle beams is a quickly developing field aimed to translate the potential advantages offered by the superior physical dose distribution and relative biological effectiveness of heavy charged particles into a real improvement of tumor therapy. To this purpose the new proton and light-ion radiation therapy facilities must be designed according to strict clinical specifications to provide a reliable and effective tool against cancer. This paper provides the performance specifications of the accelerator and of the beam transport and delivery systems of the Italian Hadrontherapy Centre, which should be satisfied to meet the clinical specifications. A discussion is given on the requirements on energy range, energy variability, beam intensity, lateral penumbra, distal dose falloff, source-to-surface distance, time structure of the extracted beam, raster scanning system specifications, and beam abort time. Though the physical specifications are given for a particular accelerator, they can be used as a general guideline for the design of future biomedical particle accelerator facilities.
Non-Reproductive Effects of Sex Steroids: Their Immunoregulatory Role (2011)

In this special issue of Current Topics in Medicinal Chemistry, the reader will find reviewed some of the hottest topics in the field of the non-reproductive effects of sex steroids. Cabrera-Muñoz et al., show that progesterone participates in the regulation of human brain tumors growth. The contribution of Martocchia suggests that sex steroid receptor modulating drugs provide new therapeutic approaches to autoimmune diseases. The role of sex steroid participation in the differentiation of stem cells to neurones is discussed by I. Velasco. Pérez-Torres and collaborators demonstrate that sex steroids play an important role in the appearance and development of renal diseases and the metabolic syndrome, the new epidemics of our century. Paris and Frye hypthetize that gestational stress, have effects on cognitive performance and/or neuronal integrity in the fetus, and that exposure to variable stress during gestation can perturb cognitive performance, concomitant with dendrite development in hippocampus and diencephalon. Muñoz-Cruz et al. thoroughly review the growing body of evidence that shows reciprocal relationship between sex steroids and the immune system, and conclude that understanding the mechanisms of action of sex steroids on immune cells is important for further progress in the development of novel therapies for chronic diseases associated to immune dysregulation. Besides, the effects of sexual steroids on pancreatic function and diabetes are reviewed by Morimoto et al. Yanes et al. review some of the contradictions raised in the context of the recently proposed critical period hypothesis, which takes into account the frame-time after cessation of ovarian function. Finally, another vey intetresting aspect of the non-reproductive effects of sex-steroids, is the related to some cognition-related aspects, which is reviewed by Picazo et al.
Expression of Ret finger protein correlates with outcomes in endometrial cancer (2009)

Ret finger protein (RFP) is a nuclear protein with transcriptional repressive activity that is highly expressed in a variety of human and rodent tumor cell lines. We examined the expression of RFP in human endometrial cancer and assessed its clinical significance. Formalin-fixed, paraffin-embedded sections from endometrial cancer tissues were immunostained with the RFP antibody, and the staining intensity was evaluated. The clinicopathological factors examined were age, International Federation of Gynecology and Obstetrics stage, tumor grade, myometrial invasion, and pelvic lymph node metastasis. Overall survival (OS) and progression-free survival (PFS) were evaluated using the Kaplan-Meier method, and multivariate analysis was performed using the Cox proportional hazard analysis. Of the 119 cancer tissues, 57 (47.9%) cases were positive for RFP immunoreactivity. RFP expression was not associated with any of the clinicopathological parameters examined. However, positive RFP expression significantly predicted poorer OS and PFS compared with negative expression (OS, P = 0.0011; PFS, P < 0.0001). In the multivariate analyses, positive RFP expression was an independent prognostic factor for survival in this study. RFP knockdown significantly impaired cancer cell migration and invasion in vitro with concomitant decreases of integrins beta1 and alpha2. Positive RFP expression is a predictive marker for an unfavorable clinical outcome in patients with endometrial cancer.
Inhibition of p38 MAPK Signaling Augments Skin Tumorigenesis via NOX2 Driven ROS Generation (2014)

p38 mitogen-activated protein kinases (MAPKs) respond to a wide range of extracellular stimuli. While the inhibition of p38 signaling is implicated in the impaired capacity to repair ultraviolet (UV)-induced DNA damage-a primary risk factor for human skin cancers-its mechanism of action in skin carcinogenesis remains unclear, as both anti-proliferative and survival functions have been previously described. In this study, we utilized cultured keratinocytes, murine tumorigenesis models, and human cutaneous squamous cell carcinoma (SCC) specimens to assess the effect of p38 in this regard. UV irradiation of normal human keratinocytes increased the expression of all four p38 isoforms (α/β/γ/δ); whereas irradiation of p53-deficient A431 keratinocytes derived from a human SCC selectively decreased p38α, without affecting other isoforms. p38α levels are decreased in the majority of human cutaneous SCCs assessed by tissue microarray, suggesting a tumor-suppressive effect of p38α in SCC pathogenesis. Genetic and pharmacological inhibition of p38α and in A431 cells increased cell proliferation, which was in turn associated with increases in NAPDH oxidase (NOX2) activity as well as intracellular reactive oxygen species (ROS). These changes led to enhanced invasiveness of A431 cells as assessed by the matrigel invasion assay. Chronic treatment of p53-/-/SKH-1 mice with the p38 inhibitor SB203580 accelerated UV-induced SCC carcinogenesis and increased the expression of NOX2. NOX2 knockdown suppressed the augmented growth of A431 xenografts treated with SB203580. These findings indicate that in the absence of p53, p38α deficiency drives SCC growth and progression that is associated with enhanced NOX2 expression and ROS formation.
Analog/RF Performance of Si Nanowire MOSFETs and the Impact of Process Variation (2007)

In this paper, the analog/RF performance of Si nanowire transistors (SNWTs) and the impact of process variation are investigated for the first time. Analog/RF figures of merit of SNWTs are studied, including transconductance efficiency g <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">m</sub> /I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">d</sub> , intrinsic gain g <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">m</sub> /g <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">d</sub> , cutoff frequency f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">t </sub> , and maximum oscillation frequency f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">max</sub> . The results indicate that SNWTs exhibit superior intrinsic RF scaling capability and are suitable for low-power analog/RF applications. The impact of nanowire cross-sectional shape fluctuation that is caused by process variation is studied and found to be relatively severe, and the acceptable variation tolerance for RF integrated circuit design is given
High density DNA data storage library via dehydration with digital microfluidic retrieval (2019)

DNA promises to be a high density data storage medium, but physical storage poses a challenge. To store large amounts of data, pools must be physically isolated so they can share the same addressing scheme. We propose the storage of dehydrated DNA spots on glass as an approach for scalable DNA data storage. The dried spots can then be retrieved by a water droplet using a digital microfluidic device. Here we show that this storage schema works with varying spot organization, spotted masses of DNA, and droplet retrieval dwell times. In all cases, the majority of the DNA was retrieved and successfully sequenced. We demonstrate that the spots can be densely arranged on a microfluidic device without significant contamination of the retrieval. We also demonstrate that 1 TB of data could be stored in a single spot of DNA and successfully retrieved using this method.
