Endogenous Neurotrophins Are Required for the Induction of GABAergic Long-Term Potentiation in the Neonatal Rat Hippocampus (2005)

In the developing rat hippocampus, GABAergic synapses undergo a Ca2+-dependent long-term potentiation (LTP(GABA-A)); this form of synaptic plasticity is induced in CA3 pyramidal neurons by delivering repetitive depolarizing pulses (DPs) to the recorded neuron, and it is expressed as a long-lasting increase in the frequency and amplitude of spontaneous GABA(A) receptor-mediated postsynaptic currents. In the present study, we examined the role of endogenous tropomyosin-related kinase receptor B (TrkB) receptor ligands and associated protein tyrosine kinases (PTKs) in the induction of LTP(GABA-A). The application of Lavendustin A, a broad spectrum PTK inhibitor, blocked the induction of LTP(GABA-A), whereas Lavendustin B, its inactive form, had no effect. Moreover, k-252a and k-252b, two alkaloids that inhibit the kinase activity of the Trk receptor family, also prevented the induction of LTP(GABA-A). On hippocampal slices incubated with the soluble form of TrkB receptor IgG (TrkB-IgG), which prevents the activation of TrkB receptors by endogenous ligands, DPs failed to induce LTP(GABA-A), whereas the incubation with TrkA-IgG or TrkC-IgG had no such effect. Altogether, these data indicate that endogenous TrkB ligands and associated PTK activity are necessary for the induction of GABAergic LTP in the developing rat hippocampus.
Looking at projected documents: event detection & document identification (2005)

In the context of a multimodal application, the article proposes an image-based method for bridging the gap between document excerpts and video extracts. The approach, called document image alignment, takes advantage of the observable events related to documents that are visible during meetings. In particular, the article presents a new method for detecting slide changes in slideshows, its evaluation, and a preliminary work on document identification.
Cache Organizations for H.264/AVC Motion Compensation (2007)

A large demand on memory bandwidth puts limitation on the performance improvement of an H.264/AVC decoder. In order to reduce the amount of frame memory access, this paper proposes a new memory architecture that uses a cache memory to store the data for motion compensation. Optimized for the data access pattern of motion compensation, two new cache organizations are proposed to reduce cache conflict misses. A split-index direct mapped cache maps a page of a frame memory into two consecutive cache lines by turns. Another cache organization, called a circular cache, does not fetch the entire line of a cache but reads only the necessary part of a cache line. A block pre-fetching scheme is proposed to prefetch a block of data which is likely to be used by the motion compensation of the next block. With the circular cache and block pre-fetching, a frame memory bandwidth requirement is reduced by an average of 72% which is 5% better than the previous work. In addition, the number of the non-sequential data accesses is reduced by an average of 68%.
Dimethoxycurcumin, a Synthetic Curcumin Analogue, Induces Heme Oxygenase-1 Expression through Nrf2 Activation in RAW264.7 Macrophages (2009)

Curcumin [1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dione] induces heme oxygenase-1 (HO-1) expression via activation of the nuclear factor-erythroid-2-related factor 2 (Nrf2), whereas tetrahydrocurcumin [1,7-bis(4-hydroxy-3-methoxyphenyl)-3,5-heptanedione], one of curcumin in vivo metabolites, has no effect on HO-1 expression and Nrf2 activation. The aim of this study was to investigate whether dimethoxycurcumin [1,7-bis(4,3-dimethoxyphenyl)-1,6-heptadiene-3,5-dione], a synthetic curcumin analogue with higher metabolic stability over curcumin, could induce HO-1 expression to the same extent as curcumin in RAW264.7 macrophages. Dimethoxycurcumin and curcumin, but not tetrahydrocurcumin, induced HO-1 expression and Nrf2 nuclear translocation, suggesting that the unsaturated nature of the diarylheptanoid chain of the compounds are crucial for HO-1 expression and Nrf2 activation. Blockage of Nrf2 synthesis by small interfering RNA abolished HO-1 expression by dimethoxycurcumin, indicating that dimethoxycurcumin may induce HO-1 expression via Nrf2 activation. In comparison, dimethoxycurcumin and curcumin had about the same effect on HO-1 expression, suggesting that dimethoxycurcumin retains the HO-1-inducing activity of its parent compound curcumin in RAW264.7 macrophages.
Development in Artificial Joints Materials, Analysis and Manufacture Techniques.(Dept.M) (2021)

Engineering materials, in many forms have been implanted into the human body since the end of the eighteenth century. Implant surgery has developed to the extent that implants are now used in most branches of surgery and are becoming increasingly more sophisticated. Orthopaedic surgery uses more implants than any other branch of medicine. In the last decade, various joint replacements have been developed. However, many implants have failed in the past and even now there are occasional failures. Many of the failures are attributed to poorly chosen or badly used materials, high stress concentration leading to crack initiation and growth, loosening of the implant due to a poor fixation and/or a non-adequate adhesion between the implant/cement/bone interfaces. The present paper reviews the development in artificial implants during the last decade considering materials, analysis and manufacture processes.
Axenfeld-Rieger syndrome: new perspectives: Figure 1 (2011)

Axenfeld-Rieger syndrome is a genetic disease affecting multiple organ systems. In the eye, this condition manifests with varying degrees of anterior segment dysgenesis and carries a high risk of glaucoma. Other associated systemic issues include cardiovascular outflow tract malformations, craniofacial abnormalities and pituitary abnormalities, which can result in severe endocrinological sequelae. Recent advances in molecular genetics have identified two major genes, PITX2 and FOXC1, demonstrating a wide spectrum of mutations, which aids in the molecular diagnosis of the disease, although evidence exists to implicate other loci in this condition. The management of individuals affected by Axenfeld-Rieger syndrome requires a multidisciplinary approach and would include dedicated surveillance and management of glaucoma, sensorineural hearing loss, and cardiac, endocrinological, craniofacial and orthopaedic abnormalities.
Multicrystalline LLC-Si thin film solar cells on low temperature glass (2003)

Multicrystalline silicon thin film solar cells with a grain size of about 100 /spl mu/m were prepared on a borosilicate glass substrate by the LLC (Layered Laser Crystallization) process. This process consists of depositing a-Si by PECVD, crystallizing a highly p-doped seed layer by scanning the beam of a cw laser, and epitaxially thickening the seed by further depositing a-Si and applying pulses of an excimer laser periodically during deposition. Doping profiles for absorber and emitter are introduced by adding diborane or phosphine during PECVD. The seed acts as a transparent electrode. Solar cells 2 /spl mu/m thick show a V/sub oc/ of 545 mV, a fill factor of up to 71%, and an efficiency of 3.3%.
Anti-Infective Action of Immuno-modulating Polysaccharides (&#946;-Glucan and Plantago Major L. Pectin) against Intracellular (Mycobacteria sp.) and Extracellular (Streptococcus Pneumoniae sp.) Respiratory Pathogens (2003)

The increasing occurrence of resistance to antibiotics among major respiratory pathogens has become a public health threat calling for new therapeutics. β-1,3-D-glucan is a polyglucose from yeast and moulds with known anti-infection and anti-tumor effects in rodent models. Recently, biologically active polysaccharides have also been isolated from Plantago major L., which has traditionally been used for wound healing. The aim of the current review is to examine whether stimulation of the hosts immune system with such immuno-modulators c ould help the host c omba t inf e ctions with potentia lly har mf ul re spira tor y pa thoge ns. Studie s w e re performed with mice stimulated with β-1,3-glucan or P. major polysaccharide and infected either with the intracellular pathogen Mycobacterium bovis, BCG, or the extracellular pathogen Streptococcus pneumoniae. In addition, the effect of the agents on M. tuberculosis-infected macrophages was examined in vitro. It was found that β-glucans protected against M. bovis, BCG and S. pneumoniae infections in vivo both when injected before and after challenge. Moreover, β-glucans reduced growth of M. tuberculosis in macrophage cultures. P. major L. pectin polysaccharide did also protect against S. pneumoniae infection in mice. The anti-infective action of P. major L. pectin polysaccharide in mice was shown to be due to stimulation of the innate immune system, which is also the mechanism for the observed β-glucan effect. Thus, in the future, biologically active polysaccharides or other substances that stimulate the innate immune system, may prove to be useful alternative compounds in the fight against respiratory tract and other infections caused by multi-drug resistant pathogens.

Inhibitory effects of SY0916, a platelet-activating factor receptor antagonist, on the angiogenesis of human umbilical vascular endothelial cells (2011)

SY0916 is a novel platelet-activating factor receptor antagonist. The objective of this study is to explore the anti-angiogenesis effects of SY0916 on human umbilical vascular endothelial cell (HUVEC) and to understand its possible mechanism. The effect of SY0916 on proliferation of HUVEC was measured by the MTT method, whereas the effect of SY0916 on HUVEC chemotaxis was carried out by Boyden chamber assay. The activities of metalloproteinase (MMP)-9 and MMP-2 were detected using gelatin zymography, and the expression of intercellular adhesion molecules-1 (ICAM-1) was measured by Western blot analysis. The 2D tube formation experiment of HUVEC with 10% fetal calf serum on Matrigel was also evaluated. It was shown that SY0916 had significant inhibitory effects on the proliferation and the chemotaxis of HUVEC induced by phorbol-12-myristate-13-acetate in a positive dose-dependent manner. Furthermore, SY0916 could significantly suppress the activity of MMP-2 and MMP-9 and decrease the expression of ICAM-1 in HUVEC. In 2D tube formation test, SY0916 could effectively inhibit the formation of vascular structure on Matrigel. The results showed that SY0916 could block the chemotaxis of HUVEC, and then inhibit the tube formation on Matrigel. Such anti-angiogenesis effect of SY0916 on HUVEC might relate to downregulate the expressions of MMP-2, MMP-9, and ICAM-1.
Antimicrobial therapies for Q fever (2013)

Q fever is caused by the bacterium Coxiella burnetii and has both acute and chronic forms. The acute disease is a febrile illness often with headache and myalgia that can be self-limiting, whereas the chronic disease typically presents as endocarditis and can be life threatening. The normal therapy for the acute disease is a 2 week course of doxycycline, whereas chronic disease requires 18-24 months of doxycycline in combination with hydroxychloroquine. Alternative treatments are used for pregnant women, young children and those who cannot tolerate doxycycline. Doxycycline resistance is rare, but has been reported. Co-trimoxazole is a currently recommended alternative treatment, but quinolones, rifampin and newer macrolides may also provide some benefit.
The Modularity of Mind (1983)

This study synthesizes current information from the various fields of cognitive science in support of a new and exciting theory of mind. Most psychologists study horizontal processes like memory and information flow; Fodor postulates a vertical and modular psychological organization underlying biologically coherent behaviors. This view of mental architecture is consistent with the historical tradition of faculty psychology while integrating a computational approach to mental processes. One of the most notable aspects of Fodor's work is that it articulates features not only of speculative cognitive architectures but also of current research in artificial intelligence.

Suppression of prostate tumor cell growth in vivo by WT1, the Wilms' tumor suppressor gene (2004)

The primary form of therapy for prostate cancer is androgen ablation resulting in apoptosis and expression of apoptotic genes (i.e. par-4). Prostate cancer cells that survive androgen ablation therapy express pro-survival genes (i.e. bcl-2) permitting these androgen independent (AI) cells to overcome apoptotic signals and proliferate in the absence of normal growth signals. To disrupt tumor growth and progression to AI, we expressed the tumor suppressor gene, WT1 in LNCaP prostate tumor cells. The WT1 transcription factor modulates expression and activity of several prostate growth control genes (i.e. par-4, bcl-2 and AR) in vitro. To provide insight into potential mechanisms of prostate cancer growth suppression both the transcriptionally active form of wild-type WT1 (D) and an inactive WT1 (D) R394W mutant form were stably transfected in LNCaP cells. Surprisingly both transfected lines underwent apoptosis and were growth suppressed in nude mice. A 3-fold reduction in overall tumor incidence and volume was associated with increased apoptosis, as evidenced by DNA fragmentation and par-4 expression, and was reduced or absent in early forming LNCaP tumors. After several months the indolent WT1-LNCaP cells became proliferative forming small tumors lacking par-4 protein. Although bcl-2 protein was present in all LNCaP tumors at this late-stage, it was detected in only a minority of WT1-LNCaP tumors, suggesting that pro-survival signals continued to be reduced in WT1-suppressed tumor cells. While the mechanisms of WT1-mediated growth suppression and apoptosis in LNCaP tumor cells are unknown, our results argue against simple transcriptional regulation since the mutant WT1 (D) R394W suppressed tumor formation similarly to wild-type WT1. This suggests that the mechanism of WT1-mediated growth suppression does not rely upon DNA binding at known WT1 recognition sites.

Technique for minimizing branch delay due to incorrect branch history table predictions (1982)

The proposed solution for reducing branch delay is as follows: (a) to introduce a very accurate decode-time branch prediction mechanism so that the outcome of a branch is known with a high degree of accuracy before the branch is resolved at execution time; and (b) to use an appropriate algorithm for the coordination of the two predictions (one by the mechanism and the other by the bht) to minimize the impact of wrong predictions by either.
Low-Magnitude High-Frequency Vibration Inhibits RANKL-Induced Osteoclast Differentiation of RAW264.7 Cells (2012)

Osteoclasts are the key participants in regulation of bone mass. Low-magnitude high-frequency vibration (LMHFV) has been found to be anabolic to bone in vivo. This study aimed to investigate the effect of LMHFV on osteoclast differentiation in vitro. Murine monocyte cell line RAW264.7 cells in the presence of receptor activator of nuclear factor-kappaB ligand (RANKL) were treated with or without LMHFV at 45 Hz (0.3 g) for 15 min day(-1). Tartrate resistant acid phosphatase (TRAP)-positive multinucleated cells (MNCs) and actin ring formation were evaluated. Expression of the osteoclast-specific genes, such as cathepsin K, matrix metallopeptidase-9 (MMP-9) and TRAP, were analyzed using real time-PCR. c-Fos, an osteoclast-specific transcription factor, was determined using Western blot. We found that LMHFV significantly decreased the number of RANKL-induced TRAP-positive MNCs (P<0.01), and inhibited the actin ring formation. The mRNA expression of the cathepsin K, MMP-9 and TRAP were down-regulated by LMHFV intervention (all P<0.001). Furthermore, LMHFV also inhibited the expression of c-Fos protein in the RANKL-treated RAW264.7 cells (P<0.05). Our results suggest that LMHFV can inhibit the RANKL-induced osteoclast differentiation of RAW264.7 cells, which give some new insight into the anabolic effects of LMHFV on bone.
Kava-kava Extract WS 1490 versus Placebo in Anxiety Disorders - A Randomized Placebo-controlled 25-week Outpatient Trial (1997)

101 outpatients suffering from anxiety of non-psychotic origin (DSM-III-R criteria: agoraphobia, specific phobia, generalized anxiety disorder, and adjustment disorder with anxiety) were included in a 25-week multicenter randomized placebo-controlled double-blind trial with WS 1490, a special extract of kava-kava. In the main outcome criterion, the Hamilton Anxiety Scale (HAMA), there was a significant superiority of the test drug starting from week 8 on. WS 1490 was also found to be superior with respect to the secondary outcome variables. HAMA subscores somatic and psychic anxiety, Clinical Global Impression, Self-Report Symptom Inventory-90 Items revised, and Adjective Mood Scale. Adverse events were rare and distributed evenly in both groups. These results support WS 1490 as a treatment alternative to tricyclic antidepressants and benzodiazepines in anxiety disorders, with proven long-term efficacy and none of the tolerance problems associated with tricyclics and benzodiazepines.

A low-power charge-recycling ROM architecture (2003)

This paper describes a newly proposed low-power charge-recycling read-only memory (CR-ROM) architecture. The CR-ROM reduces the power consumption in bit lines, word lines, and precharge lines by recycling the previously used charge. In the proposed CR-ROM, bit-line swing voltage is lowered by the charge recycling between bit lines. When N bit lines recycle their charges, the swing voltage and the power of the bit lines become 1/N and 1/N/sup 2/ compared to the conventional ROMs, respectively. As the number of N increases, the power saving in bit lines becomes salient. Also, power consumption in word lines and precharge lines can be reduced theoretically to half by the proposed charge-recycling techniques. The simulation results show that the CR-ROM consumes 60%/spl sim/85% of the conventional low-power ROMs with 1 K /spl times/ 32 b. A CR-ROM with 32 Kb was implemented in a 0.35-/spl mu/m CMOS process. The power dissipation is 6.60 mW at 100 MHz with 3.3 V and the maximum operating clock frequency is 150 MHz.
Overall tree and leaf unit transpiration variations in the Acacia tortilis under deficient rainfall conditions (2003)

In the Ferlo area, in Northern Senegal, seasonal transpiration variations at both tree and leaf levels are characterized and compared under favourable and deficient rainfall conditions (268 mm\year and 146 mm\year, respectively). Meanwhile, several relations are established using a few factors from the soil‐plant‐atmosphere system (soil water content in the upper layers, leaf phenology, and evaporative demand). Annually, the amount of water transpired by leaf unit area is 295 L.m‐ 2 in favourable periods and 300 L.m‐ 2 in deficient periods. Leaf transpiration is not affected by unfavourable rainfall conditions. The influence of deficient vapour pressure on the seasonal variation of single leaf transpiration is discussed. At tree level, the intensity of the transpiratory flow (delta) as estimated by the difference between the reference and minimal leaf water potentials shows a 30% decrease while the duration of the full foliation phase is shortened during the deficient year. The single leaf transpiration which is quantitatively the same under favourable and deficient conditions implies that the reduction of the whole tree transpiration is due to a decrease in the whole tree foliage area. Owing to its ability to adapt to inter‐annual rainfall fluctuations, this species should be recommended in the afforestation programs developed in the Sahel.
Design definition of a microwave power reception and conversion system for use on a high altitude powered platform (1981)

The design definition of a microwave power reception and conversion system for use on high altitude powered platform is presented. The study includes an initial design, construction and test effort on a thin film, printed circuit rectenna. A study of a low altitude demonstration of an airborne rectenna was made starting with the assumption that a fifty foot mechanically steerable parabolic reflector at the Wallops Flight Center would be retrofitted with a low microwave power source consisting of a five kilowatt commercially available magnetron and that a small blimp would be used to support the rectenna.
