Estrogen mediates inflammatory role of mast cells in endometriosis pathophysiology (2022)

Endometriosis is an estrogen dependent, chronic inflammatory disease characterized by the growth of endometrial lining outside of the uterus. Mast cells have emerged as key players in regulating not only allergic responses but also other mechanisms such as angiogenesis, fibrosis, and pain. The influence of estrogen on mast cell function has also been recognized as a potential factor driving disease pathophysiology in number of allergic and chronic inflammatory conditions. However, precise information is lacking on the cross talk between endocrine and immune factors within the endometriotic lesions and whether that contributes to the involvement of mast cells with disease pathophysiology. In this study, we observed a significant increase in mast cell numbers within endometriotic lesions compared to matched eutopic endometrium from the same patients. Compared to eutopic endometrium, endometriotic lesions had significantly higher levels of stem cell factor (SCF), a potent growth factor critical for mast cell expansion, differentiation, and survival for tissue resident mast cells. Targeted mRNA Q-PCR array revealed that the endometriotic lesions harbour microenvironment (upregulation of CPA3, VCAM1, CCL2, CMA1, CCR1, and KITLG) that is conducive to mast cells recruitment and subsequent differentiation. To examine cross-talk of mast cells within the endometriotic lesion microenvironment, endometriotic epithelial cells (12Z) and endometrial stromal cells (hESC) incubated with mast cell-conditioned media showed significantly increased production of pro-inflammatory and chemokinetic cytokines. To further understand the impact of estrogen on mast cells in endometriosis, we induced endometriosis in C57BL/6 mice. Mature mast cells were significantly higher in peritoneal fluid of estrogen-treated mice compared to untreated mice within the sham operated groups. Mouse endometriotic lesion tissue revealed several genes (qRT-PCR) relevant in mast cell biology significantly upregulated in the estrogen treated, endometriosis-induced group compared to control endometrium. The endometriotic lesions from estrogen treated mice also had significantly higher density of Alcian blue stained mast cells compared to untreated lesions or control endometrium. Collectively, these findings suggest that endometriotic lesions provide a microenvironment necessary for recruitment and differentiation of mast cells. In turn, mast cells potentially release pro-inflammatory mediators that contribute to chronic pelvic pain and endometriosis disease progression.
Theory of the Time-Reversal Operator for a Dielectric Cylinder Using Separate Transmit and Receive Arrays (2009)

The DORT method applies to scattering analysis with arrays of transceivers. It consists in the study of the time-reversal invariants. In this paper, a large dielectric cylinder is observed by separate transmit and receive arrays with linear polarizations, E or H, parallel to its axis. The decomposition of the scattered field into normal modes and projected harmonics is used to determine the theoretical time-reversal invariants. It is shown that the number of invariants is about 2 <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</i> <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">a</i> , where <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">a</i> is the cylinder radius and <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</i> <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> the wave number in the surrounding medium.

Development and Evaluation of a System for the Semi-Quantitative Determination of the Physical Properties of Skin After Exposure to Silver Nanoparticles (2020)

In order to ensure the safe usage of silver nanoparticles (nAgs) in cosmetics, it is necessary to reveal the physical properties of nAgs inside the skin, as these properties may change during the process of percutaneous absorption. In this study, we aimed to establish an analytical system based on single particle inductively coupled plasma mass spectrometry (sp-ICP-MS) to determine the physical properties of nAgs in the skin. First, we optimized a pretreatment method for solubilizing the skin samples and then showed that most of the nAgs were recovered by sodium hydroxide treatment while remaining in particle form. For separating the skin into the epidermis and dermis, we screened several conditions of microwave irradiation. The sp-ICP-MS analysis indicated that the application of 200 W for 30 s was optimal, as this condition ensured complete separation of skin layers without changing the physical properties of the majority of nAgs. Finally, we evaluated the in vivo application by analyzing the quantity as well as the physical properties of Ag in the epidermis, dermis, and peripheral blood of mice after exposing the skin to nAgs or Ag<sup>+</sup>. Subsequent sp-ICP-MS analysis indicated that nAgs could be absorbed and distributed into the deeper layers in the ionized form, whereas Ag<sup>+</sup> was absorbed and distributed without a change in physical properties. This study indicates that in order to obtain a comprehensive understanding of the response of skin following exposure to nAgs, it is essential to consider the distribution and particle size of not only nAgs but also Ag<sup>+</sup> released from nAgs into the skin.
Affordable oral health care: dental biofilm disruption using chloroplast made enzymes with chewing gum delivery (2021)

Current approaches for oral health care rely on procedures that are unaffordable to impoverished populations, whereas aerosolized droplets in the dental clinic and poor oral hygiene may contribute to spread of several infectious diseases including COVID-19, requiring new solutions for dental biofilm/plaque treatment at home. Plant cells have been used to produce monoclonal antibodies or antimicrobial peptides for topical applications to decrease colonization of pathogenic microbes on dental surface. Therefore, we investigated an affordable method for dental biofilm disruption by expressing lipase, dextranase or mutanase in plant cells via the chloroplast genome. Antibiotic resistance gene used to engineer foreign genes into the chloroplast genome were subsequently removed using direct repeats flanking the aadA gene and enzymes were successfully expressed in marker-free lettuce transplastomic lines. Equivalent enzyme units of plant-derived lipase performed better than purified commercial enzymes against biofilms, specifically targeting fungal hyphae formation. Combination of lipase with dextranase and mutanase suppressed biofilm development by degrading the biofilm matrix, with concomitant reduction of bacterial and fungal accumulation. In chewing gum tablets formulated with freeze-dried plant cells, expressed protein was stable up to 3 years at ambient temperature and was efficiently released in a time-dependent manner using a mechanical chewing simulator device. Development of edible plant cells expressing enzymes eliminates the need for purification and cold-chain transportation, providing a potential translatable therapeutic approach. Biofilm disruption through plant enzymes and chewing gum-based delivery offers an effective and affordable dental biofilm control at home particularly for populations with minimal oral care access.
How to Securely Replicate Services (Preliminary Version) (1992)

A method is presented for constructing replicated services that retain their availability and integrity despite several servers and clients being corrupted by an intruder, in addition to others failing benignly. More precisely, a service is replicated by 'n' servers in such a way that a correct client will accept a correct server's response if, for some prespecified parameter, k, at least k servers are correct and fewer than k servers are correct. The issue of maintaining causality among client requests is also addressed. A security breach resulting from an intruder's ability to effect a violation of causality in the sequence of requests processed by the service is illustrated. An approach to counter this problem is proposed that requires that fewer than k servers are corrupt and, to ensure liveness, that k is less than or = n - 2t, where t is the assumed maximum total number of both corruptions and benign failures suffered by servers in any system run. An important and novel feature of these schemes is that the client need not be able to identify or authenticate even a single server. Instead, the client is required only to possess at most two public keys for the service.
Lipocalin‐type prostaglandin D synthase is up‐regulated in oligodendrocytes in lysosomal storage diseases and binds gangliosides (2006)

Lipocalin-type prostaglandin (PG) D synthase (L-PGDS) is a dually functional protein, acting both as a PGD2-synthesizing enzyme and as an extracellular transporter of various lipophilic small molecules. L-PGDS is expressed in oligodendrocytes (OLs) in the central nervous system and is up-regulated in OLs of the twitcher mouse, a model of globoid cell leukodystrophy (Krabbe's disease). We investigated whether up-regulation of L-PGDS is either unique to Krabbe's disease or is a more generalized phenomenon in lysosomal storage disorders (LSDs), using LSD mouse models of Tay-Sachs disease, Sandhoff disease, GM1 gangliosidosis and Niemann-Pick type C1 disease. Quantitative RT-PCR revealed that L-PGDS mRNA was up-regulated in the brains of all these mouse models. In addition, strong L-PGDS immunoreactivity was observed in OLs, but not in either astrocytes or microglia in these models. Thus, up-regulation of L-PGDS appears to be a common response of OLs in LSDs. Moreover, surface plasmon resonance analyses revealed that L-PGDS binds GM1 and GM2 gangliosides, accumulated in neurons in the course of LSD, with high affinities (KD = 65 and 210 nm, respectively). This suggests that L-PGDS may play a role in scavenging harmful lipophilic substrates in LSD.
Complete Genome Sequence of the Hyperthermophilic Cellulolytic Crenarchaeon “Thermogladius cellulolyticus” 1633 (2012)

Strain 1633, a novel member of the genus Thermogladius, isolated from a freshwater hot spring, is an anaerobic hyperthermophilic crenarchaeon capable of fermenting proteinaceous and cellulose substrates. The complete genome sequence reveals genes for protein and carbohydrate-active enzymes, the Embden-Meyerhof pathway for glucose metabolism, cytoplasmic NADP-dependent hydrogenase, and several energy-coupling membrane-bound oxidoreductases.
Dynamic optical methods for direct laser written waveguides (2013)

Direct laser writing is widely used to fabricate 3D waveguide devices by modi cation of a materials refractive index. The fabrication delity depends strongly on focal spot quality, which in many cases is impaired by aberrations, particularly spherical aberration caused by refractive index mismatch. We use adaptive optics to correct aberration and maintain fabrication performance at a range of depths. Adaptive multifocus methods are also shown for increasing the fabrication speed for single waveguides.
5.1: Analysis of the Anisotropy of Bend Transition for OCB LCD with Low Initialization Voltage (2008)

Abstract To improve the efficiency of bend transition in OCB, its anisotropy was analyzed. The transition antiparallel (opposite) to the rubbing direction was significantly fast and this anisotropy remained at low temperatures. We propose two effects of LC shear flow on the anisotropy. Based on a pixel design that takes the anisotropy into consideration, 40% reduction of the initialization voltage in a 3‐inch TFT‐LCD has been achieved.
Altered leaf colour is associated with increased superoxide‐scavenging activity in aureusidin‐producing transgenic plants (2012)

The health-promoting property of diets rich in fruits and vegetables is based, in part, on the additive and synergistic effects of multiple antioxidants. In an attempt to further enhance food quality, we introduced into crops the capability to synthesize a yellow antioxidant, aureusidin, that is normally produced only by some ornamental plants. For this purpose, the snapdragon (Antirrhinum majus) chalcone 4'-O-glucosyltransferase (Am4'CGT) and aureusidin synthase (AmAs1) genes, which catalyse the synthesis of aureusidin from chalcone, were expressed in tobacco (Nicotiana tabacum) and lettuce (Lactuca sativa) plants that displayed a functionally active chalcone/flavanone biosynthetic pathway. Leaves of the resulting transgenic plants developed a yellow hue and displayed higher superoxide dismutase (SOD) inhibiting and oxygen radical absorbance capacity (ORAC) activities than control leaves. Our results suggest that the nutritional qualities of leafy vegetables can be enhanced through the introduction of aurone biosynthetic pathways.
A Robusta consensus genetic map using RFLP and microsatellite markers for the detection of QTL. (2005)

A segregating population of 93 individuals was created by ICCRI from the cross of two elite clones BP409 and Q121. These clones have a different genetic background, BP409 is a Congolese genotype and Q121 seems to be a hybrid between Guinean and Congolese genetic groups. After propagation by cuttings the resulting progenies were planted in two different locations in Indonesia, in order to assess the environmental effects on quantitative traits such as agronomic performances or cup quality.
Real-time Communication Through a Distributed Resource Reservation Approach (2004)

this paper aims at avoiding problems with a centralized bandwidth broker for resource reservation in a throttled real-time network, such as found in [17] [2]. A centralized broker is a single point of failure in a distributed system and is also a hot-spot resource, where all nodes of the system use for registering new real-time channels. To avoid both these problems we propose a distributed algorithm to be used instead instead of a central bandwidth broker. Also, a GlobeThrottle approach uses TCP/IP communication for channel allocation, which gives indeterministic time channels allocation. However, this problem is not addressed in this paper
Evolutionary‐Optimized Photonic Network Structure in White Beetle Wing Scales (2017)

Most studies of structural color in nature concern periodic arrays, which through the interference of light create color. The "color" white however relies on the multiple scattering of light within a randomly structured medium, which randomizes the direction and phase of incident light. Opaque white materials therefore must be much thicker than periodic structures. It is known that flying insects create "white" in extremely thin layers. This raises the question, whether evolution has optimized the wing scale morphology for white reflection at a minimum material use. This hypothesis is difficult to prove, since this requires the detailed knowledge of the scattering morphology combined with a suitable theoretical model. Here, a cryoptychographic X-ray tomography method is employed to obtain a full 3D structural dataset of the network morphology within a white beetle wing scale. By digitally manipulating this 3D representation, this study demonstrates that this morphology indeed provides the highest white retroreflection at the minimum use of material, and hence weight for the organism. Changing any of the network parameters (within the parameter space accessible by biological materials) either increases the weight, increases the thickness, or reduces reflectivity, providing clear evidence for the evolutionary optimization of this morphology.
High-efficiency, single-stage 7-kHz high-average-power ultrafast laser system (2001)

We demonstrate a simple and practical single-stage ultrafast laser amplifier system that operates at a repetition frequency from 1 to 10 kHz, with millijoule pulse energy and as much as 13 W of average power. The repetition rate can be adjusted continuously from 1 to 10 kHz by new all-solid-state pump laser technology. This is to our knowledge the highest average power ever obtained from a single-stage ultrafast laser amplifier system. This laser will significantly increase the average power and the repetition rate that is easily accessible for high-field experiments such as coherent x-ray generation or for laser-synchrotron studies.

Multidimensional Classification of Dialysis Membranes (2017)

Hemodialysis is a process of mass separation by a semipermeable membrane, utilized to cleanse blood from waste products retained in case of kidney failure. Traditionally, dialysis membranes have been classified based on composition and hydraulic conductance, creating the net differentiation between cellulosic versus non-cellulosic on one hand and low-flux versus high-flux on the other. With the evolution of biomaterials and improved spinning technology, new membranes have been introduced in the market with specific characteristics and refined individual properties. Therefore, we should consider new parameters to classify dialysis membranes including polymer blending, surface functionalization, molecular weight cut-off (MWCO), hydrophilic/hydrophobic properties, thickness and architecture, adsorption capacity, and electric potential. All these parameters may be utilized to characterize a membrane alone or in combination. Recently, a new parameter has been identified as an important element to characterize a new class of membranes. Beyond the classic MWCO describing the molecular weight at which the sieving value in pure convection = 0.1, the molecular weight retention onset (MWRO) is a new parameter that defines membrane sieving properties. The retention onset value is the molecular weight at which the sieving value = 0.9. The relationship between MWCO and MWRO describes the steepness of the sieving curve and the membrane pore size distribution with important consequences on the final mass separation process and solute removal.

Synthesis of Molybdenum and Tungsten Alkylidene Complexes That Contain the 2,6-Bis(2,4,6-triisopropylphenyl)phenylimido (NHIPT) Ligand (2015)

Molybdenum and tungsten alkylidene complexes that contain the sterically demanding hexaisopropylterphenylimido ligand, N-2,6-(2,4,6-i-Pr3C6H2)2C6H3 (NHIPT), have been prepared from Mo(N-t-Bu)2Cl2(1,2-dimethoxyethane) or W(N-t-Bu)2Cl2(pyridine)2, employing tert-butylimido ligands as sacrificial proton acceptors. These complexes include M(NHIPT)(CH-t-Bu)Cl2 (M = Mo, W), Mo(NHIPT)(CH-t-Bu)(pyrrolide)2, and Mo(NHIPT)(CH-t-Bu)(pyrrolide)(OC6F5)(CH3CN). In all cases only anti alkylidene isomers are observed in solution, as a consequence of the steric demands of the NHIPT ligand. An X-ray structure of W(NHIPT)(CH-t-Bu)Cl2 showed it to be a monomer with a disordered alkylidene that is 86% in the anti configuration and 14% in the syn configuration.

An on-chip wideband and low-loss duplexer for 3G/4G CMOS radios (2010)

A wideband integrated RF duplexer supports 3G/4G bands I, II, III, IV, and IX, and achieves a TX-to-RX isolation of more than 55dB in the transmit-band, and greater than 45dB in the corresponding receive-band across 200MHz of bandwidth. A 65nm CMOS duplexer/LNA achieves a transmit insertion loss of 2.5dB, and a cascaded receiver noise figure of 5dB with more than 27dB of gain, exceeding the commercial external duplexers performance at considerably lower cost and area.
9-ING-41, a small-molecule glycogen synthase kinase-3 inhibitor, is active in neuroblastoma (2018)

Advanced stage neuroblastoma is a very aggressive pediatric cancer with limited treatment options and a high mortality rate. Glycogen synthase kinase-3β (GSK-3β) is a potential therapeutic target in neuroblastoma. Using immunohistochemical staining, we observed positive GSK-3β expression in 67% of human neuroblastomas (34 of 51 cases). Chemically distinct GSK-3 inhibitors (AR-A014418, TDZD-8, and 9-ING-41) suppressed the growth of neuroblastoma cells, whereas 9-ING-41, a clinically relevant small-molecule GSK-3β inhibitor with broad-spectrum preclinical antitumor activity, being the most potent. Inhibition of GSK-3 resulted in a decreased expression of the antiapoptotic molecule XIAP and an increase in neuroblastoma cell apoptosis. Mouse xenograft studies showed that the combination of clinically relevant doses of CPT-11 and 9-ING-41 led to greater antitumor effect than was observed with either agent alone. These data support the inclusion of patients with advanced neuroblastoma in clinical studies of 9-ING-41, especially in combination with CPT-11.
Efficient narrow-band light emission from a single carbon nanotube p-n diode (2010)

Electrically-driven light emission from carbon nanotubes could be exploited in nano-scale lasers and single-photon sources, and has therefore been the focus of much research. However, to date, high electric fields and currents have been either required for electroluminescence, or have been an undesired side effect, leading to high power requirements and low efficiencies. In addition, electroluminescent linewidths have been broad enough to obscure the contributions of individual optical transitions. Here, we report electrically-induced light emission from individual carbon nanotube p-n diodes. A new level of control over electrical carrier injection is achieved, reducing power dissipation by a factor of up to 1000, and resulting in zero threshold current, negligible self-heating, and high carrier-to- photon conversion efficiencies. Moreover, the electroluminescent spectra are significantly narrower (ca. 35 meV) than in previous studies, allowing the identification of emission from free and localized excitons.
