UV-damaged DNA-binding Proteins Are Targets of CUL-4A-mediated Ubiquitination and Degradation (2001)

Cul-4A, which encodes a member of the cullin family subunit of ubiquitin-protein ligases, is expressed at abnormally high levels in many tumor cells. CUL-4A can physically associate with the damaged DNA-binding protein (DDB), which is composed of two subunits, p125 and p48. DDB binds specifically to UV-damaged DNA and is believed to play a role in DNA repair. We report here that CUL-4A stimulates degradation of p48 through the ubiquitin-proteasome pathway, resulting in an overall decrease in UV-damaged DNA binding activity. The R273H mutant of p48 identified from a xeroderma pigmentosium (group E) patient is not subjected to CUL-4A-mediated proteolysis, consistent with its inability to bind CUL-4A. p125 is also an unstable protein, and its ubiquitination is stimulated by CUL-4A. However, the abundance of p125 is not dramatically altered by Cul-4A overexpression. UV irradiation inhibits p125 degradation, which is temporally coupled to the UV-induced translocation of p125 from the cytoplasm into the nucleus. CUL-4A is localized primarily in the cytoplasm. These findings identify DDB subunits as the first substrates of the CUL-4A ubiquitination machinery and suggest that abnormal expression of Cul-4A results in reduced p48 levels, thus impairing the ability of DDB in lesion recognition and DNA repair in tumor cells.

The 20S Proteasome Splicing Activity Discovered by SpliceMet (2010)

The identification of proteasome-generated spliced peptides (PSP) revealed a new unpredicted activity of the major cellular protease. However, so far characterization of PSP was entirely dependent on the availability of patient-derived cytotoxic CD8+ T lymphocytes (CTL) thus preventing a systematic investigation of proteasome-catalyzed peptide splicing (PCPS). For an unrestricted PSP identification we here developed SpliceMet, combining the computer-based algorithm ProteaJ with in vitro proteasomal degradation assays and mass spectrometry. By applying SpliceMet for the analysis of proteasomal processing products of four different substrate polypeptides, derived from human tumor as well as viral antigens, we identified fifteen new spliced peptides generated by PCPS either by cis or from two separate substrate molecules, i.e., by trans splicing. Our data suggest that 20S proteasomes represent a molecular machine that, due to its catalytic and structural properties, facilitates the generation of spliced peptides, thereby providing a pool of qualitatively new peptides from which functionally relevant products may be selected.

Immunology of Diseases Associated withMalasseziaSpecies (2002)

Malassezia species are members of the human cutaneous commensal flora, in addition to causing a wide range of cutaneous and systemic diseases in suitably predisposed individuals. Studies examining cellular and humoral immune responses specific to Malassezia species in patients with Malassezia-associated diseases and healthy controls have generally been unable to define significant differences in their immune response. The use of varied antigenic preparations and strains from different Malassezia classifications may partly be responsible for this, although these problems can now be overcome by using techniques based on recent work defining some important antigens and also a new taxonomy for the genus. The finding that the genus Malassezia is immunomodulatory is important in understanding its ability to cause disease. Stimulation of the reticuloendothelial system and activation of the complement cascade contrasts with its ability to suppress cytokine release and downregulate phagocytic uptake and killing. The lipid-rich layer around the yeast appears to be pivotal in this alteration of phenotype. Defining the nonspecific immune response to Malassezia species and the way in which the organisms modulate it may well be the key to understanding how Malassezia species can exist as both commensals and pathogens.

Valve replacement in women of childbearing age: influences on mother, fetus and neonate. (2005)

Biological valves are recommended in women of childbearing age, despite the fact that no birth defects were seen in children born to women with mechanical valves on warfarin, because the teratogenic effects of warfarin may be masked by the high rate of miscarriages and therapeutic abortions in this group.
Extracellular polysaccharides from Desulfovibrio desulfuricans and Pseudomonas fluorescens in the presence of mild and stainless steel (1991)

This communication reports the presence of polysaccharides in biofilms formed by pure and mixed cultures of Desulfovibrio desulfuricans and Pseudomonas fluorescens on mild and stainless steel surfaces. The results of colorimetric assays, indicating significant differences between the amounts of neutral sugars present in these biofilms, were supported by gas chromatographic (GC)-mass spectrophotometric and GC-flame ionisation detection analyses. Neutral sugars in biofilms grown on mild steel surfaces were identified and quantified, revealing glucose as a major carbohydrate followed by mannose and galactose in all types of biofilm. Extracellular polymeric substances (EPS) precipitated from bacterial cultures grown with and without steel surfaces were also analysed for their carbohydrate content. The influence of the surfaces present in the cultures on the amount and type of sugars released into the bulk phase was established. There was significantly more carbohydrate in EPS harvested from pure and mixed cultures of D. desulfuricans incubated mild and stainless steel coupons than in EPS obtained from coupon-free cultures. No significant difference in sugar quantities was observed in EPS precipitated from cultures of P. fluorescens grown under different conditions (absence or presence of steel surfaces). The main carbohydrates identified in all types of EPS samples were mannose, glucose and galactose in order of prevalence.
An Overview of MIMO Communications—A Key to Gigabit Wireless (2004)

High data rate wireless communications, nearing 1 Gb/s transmission rates, is of interest in emerging wireless local area networks and home audio/visual networks. Designing very high speed wireless links that offer good quality-of-service and range capability in non-line-of-sight (NLOS) environments constitutes a significant research and engineering challenge. Ignoring fading in NLOS environments, we can, in principle, meet the 1 Gb/s data rate requirement with a single-transmit single-receive antenna wireless system if the product of bandwidth (measured in hertz) and spectral efficiency (measured in bits per second per hertz) is equal to 10/sup 9/. A variety of cost, technology and regulatory constraints make such a brute force solution unattractive, if not impossible. The use of multiple antennas at transmitter and receiver, popularly known as multiple-input multiple-output (MIMO) wireless, is an emerging cost-effective technology that offers substantial leverages in making 1 Gb/s wireless links a reality. The paper provides an overview of MIMO wireless technology covering channel models, performance limits, coding, and transceiver design.
Petawatt lasers based on hybrid, OPCPA-Nd:glass amplification (2009)

A Petawatt laser based on hybrid optical parametric chirped pulse amplification (OPCPA) and mixed Nd:glass has been demonstrated. This concept enables peak powers which can be scaled significantly beyond one petawatt. Higher power lasers enable access to unprecedented scientific research in the studies of high intensity physics. In this paper we discuss the laser, the potential of scaling to higher peak power and the first experiments. The laser system starts with a 100 fs pulses centered around 1058 nm from a commercial tunable Titanium:sapphire oscillator which are stretched to 112 ps/nm or about 1.8 ns. The bandwidth of the output pulse is sufficient for 115 fs pulses.

Translating pilot project success into national policy development: Two projects in Bangladesh (1987)

"This article reviews the experience of two pilot projects in Bangladesh that have addressed the question of how [operations] research can be designed to foster its utilization. In a rural field experiment [begun in 1972] in Matlab subdistrict, research has demonstrated that contraceptive services, if carefully designed and properly implemented, can influence demographic dynamics even where social and economic circumstances are not conducive to fertility change. Despite the success that Matlab represents, the project was not systematically utilized for policy until a second study [begun in 1981] was launched to address government questions concerning its replicability in the public sector programme. Results suggest that pilot projects, if fielded in conjunction with research systems for testing their replicability, can foster organizational development in contexts that are not conducive to bureaucratic change."

Pancreatic acinar cells in monolayer culture: direct trophic effects of caerulein in vitro (1986)

Adult mouse pancreatic acinar cells were cultured as monolayers on collagen gels. Cells plated in medium containing 10% fetal bovine serum (FBS), epidermal growth factor (1 nM), carbachol (1 microM), insulin (1 microM), and corticosterone (10 nM) showed adaptive and growth responses. An adaptive phase occurred over the first 4-5 days, during which there was an approximately 50% decrease in the content of protein and DNA in the cultures, and the remaining attached cells showed reduced contents of zymogen granules. Subsequently, the cells spread out, divided, and formed confluent monolayers by days 11-14. Cell division was indicated by a doubling of the content of protein and DNA between days 5 and 9 and a 13-fold increase in thymidine incorporation. Microscopic examination of 14-day cultures revealed monolayers of cuboidal cells with morphological features of pancreatic acinar cells. To determine the direct effects of cholecystokinin on pancreatic acinar cell growth, cells were cultivated in media lacking added hormones and containing only 2.5% FBS with or without caerulein, a cholecystokinin analogue. Caerulein led to a 152% increase in DNA and an 89% increase in protein at day 9. By use of a preincubation [3H]thymidine incorporation assay, caerulein induced a dose-dependent increase in [3H]thymidine incorporation and nuclear labeling index, which was detectable at 0.1 nM, one-half maximal at 1 nM, and a maximal threefold increase occurred at 10 nM concentration. The results demonstrate a direct effect of caerulein on the pancreas to induce cell growth.
Do Anesthesia Residents perceive a Benefit from participating in Bedside Tracheostomies? (2014)

The residents felt this was an essential aspect of their anesthesiology training. However they did not feel they obtained invasive airway competence. We postulate the residents relatively limited exposure may have been the cause. While we do not know the impact of this training in residency on management of a future difficult airway, the residents uniformly felt this was vital in their clinical curriculum and should be universal.
Error Corrected Sub-Monolayer Ellipsometry for Measurement of Biomolecular Interactions (2013)

Already in 1946 Alexandre Rothen from the Rockefeller Institute for Medical Research, New York published the use of ellipsometry for the measurement of antigen-antibody interactions. And he found some effects that could not be explained by the assumption that the interaction of the molecules is only of chemical nature. 55 years later we started research on antibody-antigen interaction and found similar results. To make sure that these measurements are not produced by measurement artifacts, each component of our measurement technique is error analyzed and error corrected if necessary. With such type of error corrected instrumentation we found, that there must be an interaction between antigens and antibodies that is based on longitudinal electromagnetic waves, which are able to work through thin 7 nm membranes. A similar interaction is found for the virus-antigen interaction. Our measurement results are in contrast to the assumption that the antigen-antibody and antigen-virus interaction is only of chemical nature.
Image segmentation using the student's t-test and the divergence of direction on spherical regions (2010)

We have developed a new framework for analyzing images called Shells and Spheres (SaS) based on a set of spheres with adjustable radii, with exactly one sphere centered at each image pixel. This set of spheres is considered optimized when each sphere reaches, but does not cross, the nearest boundary of an image object. Statistical calculations at varying scale are performed on populations of pixels within spheres, as well as populations of adjacent spheres, in order to determine the proper radius of each sphere. In the present work, we explore the use of a classical statistical method, the student's t-test, within the SaS framework, to compare adjacent spherical populations of pixels. We present results from various techniques based on this approach, including a comparison with classical gradient and variance measures at the boundary. A number of optimization strategies are proposed and tested based on pairs of adjacent spheres whose size are controlled in a methodical manner. A properly positioned sphere pair lies on opposite sides of an object boundary, yielding a direction function from the center of each sphere to the boundary point between them. Finally, we develop a method for extracting medial points based on the divergence of that direction function as it changes across medial ridges, reporting not only the presence of a medial point but also the angle between the directions from that medial point to the two respective boundary points that make it medial. Although demonstrated here only in 2D, these methods are all inherently <i>n</i>-dimensional.

Gibberellic acid in plant (2013)

Gibberellic acid (GA), a plant hormone stimulating plant growth and development, is a tetracyclic di-terpenoid compound. GAs stimulate seed germination, trigger transitions from meristem to shoot growth, juvenile to adult leaf stage, vegetative to flowering, determines sex expression and grain development along with an interaction of different environmental factors viz., light, temperature and water. The major site of bioactive GA is stamens that influence male flower production and pedicel growth. However, this opens up the question of how female flowers regulate growth and development, since regulatory mechanisms/organs other than those in male flowers are mandatory. Although GAs are thought to act occasionally like paracrine signals do, it is still a mystery to understand the GA biosynthesis and its movement. It has not yet confirmed the appropriate site of bioactive GA in plants or which tissues targeted by bioactive GAs to initiate their action. Presently, it is a great challenge for scientific community to understand the appropriate mechanism of GA movement in plant's growth, floral development, sex expression, grain development and seed germination. The appropriate elucidation of GA transport mechanism is essential for the survival of plant species and successful crop production.
