Verilog HDL model based thermometer-to-binary encoder with bubble error correction (2016)

This paper compares several approaches to come up with the Verilog HDL model of the thermometer-to-binary encoder with bubble error correction. It has been demonstrated that implementations of different ideas to correct bubble errors yield circuits whose parameters tremendously vary in delay, area and power consumption. The shortest delay is achieved for the design synthesized from the model which mimics a human reading temperature on classic liquid-in-glass thermometer.
Metal carbonyls as pharmaceuticals? [Ru(CO)3Cl(glycinate)], a CO-releasing molecule with an extensive aqueous solution chemistry (2007)

The pharmacologically active [Ru(CO)(3)Cl(glycinate)] is shown to be in equilibrium with [Ru(CO)(2)(CO(2)H)Cl(glycinate)](-) (isomers) at around pH 3.1 which then at physiological pH reacts with more base to give [Ru(CO)(2)(CO(2))Cl(glycinate)](2-) (isomers) or [Ru(CO)(2)(CO(2)H)(OH)(glycinate)](-) (isomers). The ease with which [Ru(CO)(3)Cl(glycinate)] reacts with hydroxide results in it producing a solution in water with a pH of around 2 to 2.5 depending on concentration and making its solutions more acidic than those of acetic acid at comparable concentrations. Acidification of [Ru(CO)(3)Cl(glycinate)] with HCl gives [Ru(CO)(3)Cl(2)(NH(2)CH(2)CO(2)H)]. The crystal structures of [Ru(CO)(3)Cl(glycinate)] and [Ru(CO)(3)Cl(2)(NH(2)CH(2)CO(2)Me)] are reported.
Targeting PGC-1α to control energy homeostasis (2007)

The prevalence of Type 2 diabetes is increasing at an alarming rate in most parts of the world. Effective therapeutic drugs are urgently needed, not only to control the disease but also to prevent or delay its progression. Therapies that target the underlying pathogenesis could, in theory, hold such potential. Recent evidence strongly suggests that impaired mitochondrial function is part of the underlying pathogenesis of insulin resistance and Type 2 diabetes. Peroxisome proliferator-activated receptor gamma co-activator-1 alpha (PGC-1alpha) is a transcription co-activator that plays a key role in regulating mitochondrial biogenesis and energy metabolism in multiple tissues. Thus, improvement and restoration of mitochondrial function and oxidative capacity through activation of PGC-1alpha could provide new treatments for metabolic diseases. A diverse array of proteins has been shown to regulate PGC-1alpha transcription and/or activity, some of which represent promising targets for pharmaceutical intervention.
An Experimental Investigation of Heat Transport Capability in a Nanofluid Oscillating Heat Pipe (2006)

An experimental investigation of a nanofluid oscillating heat pipe (OHP) was conducted to determine the nanofluid effect on the heat transport capability in an OHP. The nanofluid consisted of HPLC grade water and 1.0vol% diamond nanoparticles of 5-50nm. These diamond nanoparticles settle down in the motionless base fluid. However, the oscillating motion of the OHP suspends the diamond nanoparticles in the working fluid. Experimental results show that the heat transport capability of the OHP significantly increased when it was charged with the nanofluid at a filling ratio of 50%. It was found that the heat transport capability of the OHP depends on the operating temperature. The investigated OHP could reach a thermal resistance of 0.03°C∕W at a heat input of 336W. The nanofluid OHP investigated here provides a new approach in designing a highly efficient next generation of heat pipe cooling devices.
Reduction and inactivation of superoxide dismutase by hydrogen peroxide (1974)

Reactions of H(2)O(2) with superoxide dismutase were studied by e.p.r. (electron paramagnetic resonance) spectroscopy and other methods. In agreement with earlier work, the Cu(2+) of the enzyme is reduced by H(2)O(2), although the reaction does not go to completion and its kinetics are not simple. With dilute enzyme the time for half-reduction with 9mm-H(2)O(2) is about 150ms. It is suggested that the reaction is a one-electron reduction, involving liberation of O(2) (-). On somewhat more prolonged exposure to H(2)O(2), the enzyme is inactivated. For enzyme in dilute solution and over a limited range of H(2)O(2) concentrations, inactivation is first-order with respect to enzyme and reagent, with k=3.1m(-1).s(-1) at 20-25 degrees C. Inactivation is accompanied by marked changes in the e.p.r. and visible spectra and appears to be associated with destruction of one histidine residue per subunit. It is suggested that this histidine is close to the metal in the native enzyme and essential for its enzymic activity.
Different expression of glycogen synthase kinase-3βbetween young and old rat brains after transient middle cerebral artery occlusion (2001)

Ischemia is a common stress to human brain and is difficult to cure in older individuals. To examine the differences of the response to cerebral ischemia between young and old rat brains, distributions of glycogen synthase kinase-3beta (GSK3beta) and tau proteins were analyzed after 90 min of transient middle cerebral artery occlusion (MCAO) in young (10-11 weeks) and old (15 months) rats by immunohistochemical analyses. At 4 h of reperfusion, strong cytoplasmic and nuclear immunoreactivity for GSK3beta was induced in neurons of lamina I, II, V and VI of the cerebral cortex and dorsal caudate in young brains, while the induction was not observed in lamina I and II of old cerebral cortex. The staining in lamina V and VI and dorsal caudate then gradually decreased until seven days of reperfusion in both animal groups. The staining of tau protein and terminal deoxynucleotidyl transferase-mediated dUTP-biotin in situ nick end labeling (TUNEL) did not show any positive signals in the control brain, but showed positive signals after ischemia with a peak at 24 h and 3 days, respectively. No significant difference was observed in the temporal and spatial patterns of tau and TUNEL stainings between these two groups. These data suggest that GSK3beta may have a role in ischemic neuronal cell death, and that the different spatial expression of GSK3beta between young and old rat brains may partly explain the vulnerability of older neurons after ischemia.

Conjugated polymer–silicon nanowire array hybrid Schottky diode for solar cell application (2012)

The hybrid Schottky diode based on silicon nanowire arrays (SiNWs) and poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT:PSS) has been fabricated for high performance solar cells. The length of SiNWs on a silicon substrate, which is prepared by metal-assisted chemical etching, can be tuned by adjusting the length of the etching time. In addition, the average distances between the adjacent silicon nanowires can be controlled by changing the immersing time in a saturated PCl(5) solution. The hybrid devices are made from the SiNWs with different wire lengths and various distances between adjacent wires by spin-casting PEDOT:PSS on the silicon substrates. It is found that the length and density play leading roles in the electric output characteristics. The device made from SiNWs with optimum morphology can achieve a power conversion efficiency of 7.3%, which is much improved in comparison with that of the planar one. The measurement of the transient photovoltage decay and the analysis of the current versus voltage curve indicate that the charge recombination process is a dominant factor on the device performance.
Immunosuppressive potency of mechanistic target of rapamycin inhibitors in solid-organ transplantation (2016)

Mammalian target of rapamycin, also known as mechanistic target of rapamycin (mTOR) is a protein kinase that belongs to the PI3K/AKT/mTOR signaling pathway, which is involved in several fundamental cellular functions such as cell growth, proliferation, and survival. This protein and its associated pathway have been implicated in cancer development and the regulation of immune responses, including the rejection response generated following allograft transplantation. Inhibitors of mTOR (mTORi) such as rapamycin and its derivative everolimus are potent immunosuppressive drugs that both maintain similar rates of efficacy and could optimize the renal function and diminish the side effects compared with calcineurin inhibitors. These drugs are used in solid-organ transplantationtoinduceimmunosuppression while also promoting the expansion of CD4+CD25+FOXP3+ regulatory T-cells that could favor a scenery of immunological tolerance. In this review, we describe the mechanisms by which inhibitors of mTOR induce suppression by regulation of these pathways at different levels of the immune response. In addition, we particularly emphasize about the main methods that are used to assess the potency of immunosuppressive drugs, highlighting the studies carried out about immunosuppressive potency of inhibitors of mTOR.
Amino acid sequence of the mRNA cap-binding protein from human tissues. (1987)

The 25-kDa mRNA cap-binding protein (CBP) involved in translation was purified by affinity chromatography from human erythrocytes and rabbit reticulocytes. The sequences of eight human and seven rabbit tryptic and V8 proteolytic peptides were determined. Based on the peptide sequence data, oligodeoxynucleotide probes were synthesized and used to screen human fibroblast and lymphocyte lambda cDNA libraries. The DNA sequence obtained from recombinant lambda phage inserts was found to code for all but one peptide. A 23-base oligonucleotide was synthesized based on the DNA sequence and used to prime synthesis of cDNA from human placental mRNA to construct a third library in lambda gt10. Screening with a 22-base oligonucleotide, whose sequence was upstream from the 23-base primer, yielded numerous recombinant phages with approximately equal to 250-base inserts. The 1900-base-pair cDNA sequence compiled from all phage inserts appeared to represent the entire primary sequence of CBP (Mr 25,117). Blot analysis of human placental and HeLa mRNA revealed multiple CBP mRNA species ranging from 1925 to 2250 bases. The amino acid sequence of CBP showed homology to the cap-binding PB2 protein of influenza virus.
A High-Density Integrated Genetic Linkage and Radiation Hybrid Map of the Laboratory Rat (1999)

The laboratory rat (Rattus norvegicus) is a key animal model for biomedical research. However, the genetic infrastructure required for connecting phenotype and genotype in the rat is currently incomplete. Here, we report the construction and integration of two genomic maps: a dense genetic linkage map of the rat and the first radiation hybrid (RH) map of the rat. The genetic map was constructed in two F2 intercrosses (SHRSP x BN and FHH x ACI), containing a total of 4736 simple sequence length polymorphism (SSLP) markers. Allele sizes for 4328 of the genetic markers were characterized in 48 of the most commonly used inbred strains. The RH map is a lod >/= 3 framework map, including 983 SSLPs, thereby allowing integration with markers on various genetic maps and with markers mapped on the RH panel. Together, the maps provide an integrated reference to >3000 genes and ESTs and >8500 genetic markers (5211 of our SSLPs and >3500 SSLPs developed by other groups). [Bihoreau et al. (1997); James and Tanigami, RHdb (http:www.ebi.ac.uk/RHdb/index.html); Wilder (http://www.nih.gov/niams/scientific/ratgbase); Serikawa et al. (1992); RATMAP server (http://ratmap.gen.gu.se)] RH maps (v. 2.0) have been posted on our web sites at http://goliath.ifrc.mcw.edu/LGR/index.html or http://curatools.curagen.com/ratmap. Both web sites provide an RH mapping server where investigators can localize their own RH vectors relative to this map. The raw data have been deposited in the RHdb database. Taken together, these maps provide the basic tools for rat genomics. The RH map provides the means to rapidly localize genetic markers, genes, and ESTs within the rat genome. These maps provide the basic tools for rat genomics. They will facilitate studies of multifactorial disease and functional genomics, allow construction of physical maps, and provide a scaffold for both directed and large-scale sequencing efforts and comparative genomics in this important experimental organism.

Hierarchical Cross-Modal Talking Face Generation With Dynamic Pixel-Wise Loss (2019)

We devise a cascade GAN approach to generate talking face video, which is robust to different face shapes, view angles, facial characteristics, and noisy audio conditions. Instead of learning a direct mapping from audio to video frames, we propose first to transfer audio to high-level structure, i.e., the facial landmarks, and then to generate video frames conditioned on the landmarks. Compared to a direct audio-to-image approach, our cascade approach avoids fitting spurious correlations between audiovisual signals that are irrelevant to the speech content. We, humans, are sensitive to temporal discontinuities and subtle artifacts in video. To avoid those pixel jittering problems and to enforce the network to focus on audiovisual-correlated regions, we propose a novel dynamically adjustable pixel-wise loss with an attention mechanism. Furthermore, to generate a sharper image with well-synchronized facial movements, we propose a novel regression-based discriminator structure, which considers sequence-level information along with frame-level information. Thoughtful experiments on several datasets and real-world samples demonstrate significantly better results obtained by our method than the state-of-the-art methods in both quantitative and qualitative comparisons.
Atrial Fibrillation and the Expanding Role of Catheter Ablation: Do Antiarrhythmic Drugs Have a Future? (2008)

The main therapeutic strategies for treating atrial fibrillation include rate control, maintenance of sinus rhythm, and antiembolic treatment. Current antiarrhythmic drugs are effective in about 50% of patients and are often associated with adverse effects. Multiple trials suggest that rate control with proper anticoagulation treatment is associated with a similar prognosis to a more aggressive rhythm control strategy. Catheter ablation of atrial fibrillation has success rates that exceed currently available antiarrhythmic drugs. However, catheter ablation is an evolving technique that can result in complications. In some patients, antiarrhythmic drugs are still required following ablation. New antiarrhythmic drug strategies include developing drugs that are more atrial selective, alteration of the multichannel blocking agent, amiodarone, or the development of drugs with novel mechanisms of action such as gap junction facilitation of conduction. Although catheter ablation procedures will continue to grow, the millions of atrial fibrillation patients who will require therapy will continue to make antiarrhythmic drug therapy an important part of our ongoing therapeutic armamentarium.

Is the Social Acceptability of Psychiatric Patients Decreased by Orofacial Dyskinesia? (1994)

A group of psychiatric patients with and without orofacial dyskinesia (OFD) were filmed in pairs on videotape and a group of first-year social studies students were asked to select one candidate from each pair to fill a (simulated) job opening. A stationary picture (photograph) in which OFD was not visible and moving images (a video film) in which dyskinesia was visible were shown of each patient. The video effect, which was an indicator of the increase in popularity of a patient on the video film compared with the photograph, differed significantly between the OFD and control patients. Making the movement disability visible caused a relative decrease in the popularity of the OFD patients as opposed to an increase in the popularity of the control patients.
IgG and Complement-Mediated Tissue Damage in the Absence of C2: Evidence of a Functionally Active C2-Bypass Pathway in a Guinea Pig Model (1999)

In vitro complement-mediated lysis of heavily sensitized sheep erythrocytes by C4-deficient (C4D) guinea pig and C2-deficient (C2D) human sera was demonstrated some years ago. It was postulated that these "complement-bypass" pathways resulted from activation of C1 and components of the alternative pathway. We used normal, C2D, and C4D guinea pigs in a Forssman shock model to test the in vivo relevance of the C2- and C4-bypass pathways of complement activation. High concentrations of both anti-Forssman Ab and C2D or C4D guinea pig serum induced efficient lysis of sheep erythrocytes in vitro. The most efficient lysis was observed when IgG Ab and C2D guinea pig serum were used. Blocking either the classical pathway (treatments with EGTA-Mg2+ or soluble recombinant complement receptor type 1 (sCR1)) or the alternative pathway (treatment with heating at 50 degrees C, sCR1, or soluble recombinant CR1 lacking the first of the four long homologous repeat sequences (sCR1[desLHR-A])) inhibited lysis; both pathways were required for lysis of sheep erythrocytes by C2D and C4D guinea pig sera. i.v. injection of anti-Forssman Ab in normal guinea pigs resulted in rapid death from pulmonary shock, whereas C4D guinea pigs had no adverse effect. Surprisingly, C2D guinea pigs either died in a delayed fashion or had a sublethal reaction. sCR1 treatment prevented Forssman shock in both normal and C2D guinea pigs, whereas sCR1[desLHR-A] prevented Forssman shock only in C2D animals. Our results suggest that the C2-bypass pathway occurs in vivo to produce tissue damage. Activation of complement in the absence of C2 appears to be far more efficient than in the absence of C4.
The Catalytic Machinery of Chondroitinase ABC I Utilizes a Calcium Coordination Strategy to Optimally Process Dermatan Sulfate (2006)

The chondroitinases are bacterial lyases that specifically cleave chondroitin sulfate and/or dermatan sulfate glycosaminoglycans. One of these enzymes, chondroitinase ABC I from Proteus vulgaris, has the broadest substrate specificity and has been widely used to depolymerize these glycosaminoglycans. Biochemical and structural studies to investigate the active site of chondroitinase ABC I have provided important insights into the catalytic amino acids. In this study, we demonstrate that calcium, a divalent ion, preferentially increases the activity of chondroitinase ABC I toward dermatan versus chondroitin substrates in a concentration-dependent manner. Through biochemical and biophysical investigations, we have established that chondroitinase ABC I binds calcium. Experiments using terbium, a fluorescent calcium analogue, confirm the specificity of this interaction. On the basis of theoretical structural models of the enzyme-substrate complexes, specific amino acids that could potentially play a role in calcium coordination were identified. These amino acids were investigated through site-directed mutagenesis studies and kinetic assays to identify possible mechanisms for calcium-mediated processing of the dermatan substrate in the active site of the enzyme.

Experimental allergic encephalomyelitis animal models for analyzing features of multiple sclerosis. (2000)

Various animal models with experimental allergic encephalomyelitis (EAE) have been developed applying immunologic, virologic, toxic and traumatic parameters in order to understand features of multiple sclerosis (MS). The main simulating aspects of the EAE models and the precautions for their interpretation in determining differences and common features between EAE and MS are presented. In view of an early diagnosis of CNS lesions in human, we present with particular interest the application of human-related technologies, such as MR imaging techniques, and the development of new markers to follow the dynamic of CNS lesions in vivo in EAE animal models.
