A surface recorded vestibular evoked response to acceleration in cats (1984)

Abstract Vestibular evoked responses to repetitive acceleration stimuli were recorded by skin electrodes in cats using filtering and averaging techniques. The response is made up of six—eight waves during the first 10 msec following the stimulus. Longer latency myogenic responses had large amplitude and disappeared following the paralysis of the animals. The neurogenic waves disappeared after the destruction of both inner ears or the excision of both eighth nerves and following death. Destruction of the inner ear, or excision of the VIIIth nerve on one side leads to response patterns of excitation vs. inhibition when appropriate excitatory and inhibitory acceleration stimuli are applied. The possible generators of the evoked responses are discussed in the light of the physiology of the vestibular pathways, and the results of the present experiments suggest that the generators of the first and second waves are the vestibular nerve and vestibular nucleus respectively. In addition, the vestibular evoked response seemed to be more sensitive to ischemia of the brain than the auditory brainstem evoked response and may therefore reflect better changes in brain function.
Comparison of Sorbinil and Ponalrestat (Statil) Diminution of Proteinuria in the BB Rat (1992)

Diabetic nephropathy leading to kidney failure is a major complication of type I (insulin-dependent) diabetes mellitus and is associated with progressive proteinuria. In the present 6-month study, effects of two structurally dissimilar aldose reductase inhibitors (sorbinil and ponalrestat or Statil) were examined on prevention of proteinuria in insulin-dependent spontaneously diabetic BB rats and compared with age-matched BB resistant controls. Prior to aldose reductase inhibitor treatment, all diabetic BB rats exhibited hyperglycemia (> 300 mg/dl), glycosuria (> 2,000 mg/dl) and 24-hour urinary protein excretion ranging from 5.01 to 11.23 mg/day. After daily administration of ponalrestat (20 mg/kg) for 3 months, 24-hour urinary protein excretion was 11.53 +/- 1.76 mg/day in ponalrestat-treated rats, despite persistence of hyperglycemia (444 +/- 31 mg/dl) and glycosuria (> 2,000 mg/dl); by contrast, urinary protein excretion was 17.76 +/- 2.59 mg/day in the control group of untreated BB diabetic rats. Ponalrestat initially protected against excretion of an array of urinary proteins having molecular weights between 30,000 and 100,000 daltons. These effects sustained throughout the 4th month of treatment, tended to change toward valves in control rats by the 5th month. At the end of 6 months, ponalrestat-treated diabetic rats excreted 18.73 +/- 3.20 mg/day of protein, similar to valves in untreated BB diabetic rats; both demonstrated a 4-fold increase in urinary protein excretion when compared to age-matched BB resistant controls. Proteinuria was attributed to an increase in albumin and an array of proteins having molecular weights between 30,000 and 100,000 daltons.(ABSTRACT TRUNCATED AT 250 WORDS)
Discovery of the Irreversible Covalent FGFR Inhibitor 8-(3-(4-Acryloylpiperazin-1-yl)propyl)-6-(2,6-dichloro-3,5-dimethoxyphenyl)-2-(methylamino)pyrido[2,3-<i>d</i>]pyrimidin-7(8<i>H</i>)-one (PRN1371) for the Treatment of Solid Tumors (2017)

Aberrant signaling of the FGF/FGFR pathway occurs frequently in cancers and is an oncogenic driver in many solid tumors. Clinical validation of FGFR as a therapeutic target has been demonstrated in bladder, liver, lung, breast, and gastric cancers. Our goal was to develop an irreversible covalent inhibitor of FGFR1-4 for use in oncology indications. An irreversible covalent binding mechanism imparts many desirable pharmacological benefits including high potency, selectivity, and prolonged target inhibition. Herein we report the structure-based design, medicinal chemistry optimization, and unique ADME assays of our irreversible covalent drug discovery program which culminated in the discovery of compound 34 (PRN1371), a highly selective and potent FGFR1-4 inhibitor.

Redox metals homeostasis in multiple sclerosis and amyotrophic lateral sclerosis: a review (2018)

The effect of redox metals such as iron and copper on multiple sclerosis and amyotrophic lateral sclerosis has been intensively studied. However, the origin of these disorders remains uncertain. This review article critically describes the physiology of redox metals that produce oxidative stress, which in turn leads to cascades of immunomodulatory alteration of neurons in multiple sclerosis and amyotrophic lateral sclerosis. Iron and copper overload has been well established in motor neurons of these diseases' lesions. On the other hand, the role of other metals like cadmium participating indirectly in the redox cascade of neurobiological mechanism is less studied. In the second part of this review, we focus on this less conspicuous correlation between cadmium as an inactive-redox metal and multiple sclerosis and amyotrophic lateral sclerosis, providing novel treatment modalities and approaches as future prospects.
Effect of Antioxidant Extract from Cherries on Diabetes (2014)

Diabetes is a chronic metabolic disorder in humans constituting a major health concern today whose prevalence has continuously increased worldwide over the past few decades. Production of reactive oxygen species (ROS) and disturbed capacity of antioxidant defense in diabetic subjects have been reported. It has been suggested that enhanced production of free radicals and oxidative stress is the central event for the development of diabetic complications. Antioxidants can play an important role in the improvement of diabetes. There are many reports on the effects of antioxidants in the management of diabetes. This study aimed at evaluating the effect of antioxidant extract and purified sweet and sour Cherries on hyperglycemia, microalbumin and creatinine level in alloxan-induced diabetic rats. Thirty six adult Male Wistar rats were divided equally into six groups. Diabetes was induced in the rats by an intraperitoneal injection with 120 mg/kg body weight of alloxan. Oral administration of cherry extract at a concentration of 200 mg/kg body weight for 30 days significantly reduced the levels of blood glucose, and urinary microalbumin. Also an increase in the creatinine secretion level in urine was observed in the diabetic rats treated with the cherry extract as compared to untreated diabetic rats. In this paper, the most recent patent on the identification and treatment of diabetes is used. In conclusion, cherry antioxidant extract proved to have a beneficial effect on the diabetic rats in this study. In light of these advantageous results, it is advisable to broaden the scale of use of sweet and sour cherries extract in a trial to alleviate the adverse effects of diabetes.
Sentiment Analysis Based on Deep Learning Approaches (2018)

Many emerging social sites, famous forums, review sites, and many bloggers generate huge amount of data in the form of user sentimental reviews, emotions, opinions, arguments, viewpoints etc. about different social events, products, brands, and politics, movies etc. Sentiments expressed by the users has great effect on readers, political images, online vendors. So the data present in scattered and unstructured manner needs to be managed properly and in this context sentiment analysis has got attention at very large level. Sentiment analysis can be defined as organization of the text which is used to understand the mind-sets or feelings expressed in the form of different manners such as negative, positive, neutral, not satisfactory etc. This paper explains the sentiment analysis, its levels and different approaches which are used with sentiment analysis..

Sentiment analysis can be done using different techniques based on deep learning which is also elaborated in this paper. Thus this paper highlights latest studies regarding implementation of deep learning techniques for effective sentiment analysis.
Antithrombotic Properties of Water-Soluble Carbon Monoxide-Releasing Molecules (2012)

CORM-3 and CORM-A1 inhibited thrombosis in vivo, however CORM-A1, which slowly releases carbon monoxide, and displayed a relatively weak hypotensive effect had a more pronounced antithrombotic effect associated with a stronger inhibition of platelet aggregation associated with a decrease in active plasminogen activator inhibitor-1 concentration. In contrast, the fast CO releaser CORM-3 that displayed a more pronounced hypotensive effect inhibited thrombosis primarily through a decrease in fibrin generation, but had no direct influence on platelet aggregation and fibrynolysis.

Microfiltration performance: physicochemical aspects of whey pretreatment (1995)

SUMMARY Clarification of whey by microfiltration (MF) can be achieved after appropriate pretreatment of the feed. A control pretreatment consists of a physicochemical process comprising increased ionic calcium and pH accompanied by heat (50 °C, 15 min) to cause aggregation of complex lipid–calcium phosphate particles, which are then separated by MF. This pretreatment process was modified by increasing the temperature to 55 °C and by maintaining the pH constant during heat treatment. This modification resulted in larger calcium phosphate particles and a lower content of soluble calcium and phosphate ions. As a consequence, a longer period of MF operation, better whey clarification and lower calcium and phosphate content of the filtrate were achieved. This suggests that a loosely structured deposit was formed on the membrane surface which was less resistant to filtration than that resulting from the control pretreatment. During MF, it was necessary to avoid zones of high shear in the retentate compartment that might cause physical alteration of the aggregates.
Identification of a Novel Divergent Calmodulin Isoform from Soybean Which Has Differential Ability to Activate Calmodulin-dependent Enzymes (1995)

Calmodulin plays pivotal roles in the transduction of various Ca(2+)-mediated signals and is one of the most highly conserved proteins in eukaryotic cells. In plants, multiple calmodulin isoforms with minor amino acid sequence differences were identified but their functional significances are unknown. To investigate the biological function of calmodulins in the regulation of calmodulin-dependent enzymes, we cloned cDNAs encoding calmodulins in soybean. Among the five cDNAs isolated from soybean, designated as SCaM-1 to -5, SCaM-4 and -5 encoded very divergent calmodulin isoforms which have 32 amino acid substitutions from the highly conserved calmodulin, SCaM-1 encoded by SCaM-1 and SCaM-3. SCaM-4 protein produced in Escherichia coli showed typical characteristics of calmodulin such as Ca(2+)-dependent electrophoretic mobility shift and the ability to activate phosphodiesterase. However, the extent of mobility shift and antigenicity of SCaM-4 were different from those of SCaM-1. Moreover, SCaM-4 did not activate NAD kinase at all in contrast to SCaM-1. Also there were differences in the expression pattern of SCaM-1 and SCaM-4. Expression levels of SCaM-4 were approximately 5-fold lower than those of SCaM-1 in apical and elongating regions of hypocotyls. In addition, SCaM-4 transcripts were barely detectable in root whereas SCaM-1 transcripts were as abundant as in apical and elongating regions of hypocotyls. In conclusion, the different biochemical properties together with differential expression of SCaM-4 suggest that this novel calmodulin may have different functions in plant cells.
Screening of compounds for antimicrosporidial activity in vitro. (1998)

Relatively few effective compounds are available for treating microsporidiosis in humans. In this study, several compounds were assayed for activity against Encephalitozoon intestinalis (Cali, Kotler et Orenstein, 1993) and Vittaforma corneae Shadduck, Meccoli, Davis et Font, 1990 in vitro. Of the benzimidazoles tested, albendazole was most effective and the MIC50 values were 8.0 ng/ml and 55.0 ng/ml for E. intestinalis and V. corneae, respectively. Fumagillin and its analogue, TNP-470 were nearly equally effective against both E. intestinalis and V. corneae. The MIC50 values of fumagillin were 0.52 ng/ml and 0.81 ng/ml, and the MIC50 values of TNP-470 were 0.35 ng/ml and 0.38 ng/ml for E. intestinalis and V. corneae, respectively. In addition, 12 of 44 purines and pteridines with putative tubulin binding activity that were synthesized at Southern Research Institute (SRI), inhibited microsporidial replication by more than 50% at concentrations that were not toxic to the host cells. Several chitin synthesis/assembly inhibitors inhibited growth of the microsporidia in vitro but were toxic for the host cells making it difficult to interpret the results. One exception was lufenuron, which caused no significant toxicity to the host cells and expressed approximate MIC50 values of 2.95 micrograms/ml and 6.3 micrograms/ml against E. intestinalis and V. corneae, respectively. These results warrant further studies on albendazole, fumagillin, TNP-470, lufenuron, and the selected SRI purines and pteridines for developing therapeutic strategies for microsporidiosis.
Immunogenetic Analysis of Human Tuberculosis (1988)

An investigation was undertaken to determine if susceptibility and/or immune response to Mycobacterium tuberculosis was associated with histocompatible leukocyte antigen (HLA) phenotype frequencies of class I or II antigens. Comparisons of the HLA phenotypes of 51 Mexican-American patients with tuberculosis and 54 healthy subjects who differed in their skin-test reactivity to purified protein derivative (PPD) revealed that HLA-DR3 was significantly decreased in patients with tuberculosis, compared with healthy persons who were tuberculin skin-test positive. Although no association was observed between HLA phenotype and skin test reactivity to PPD in tuberculous patients, we did observe an increase in the HLA-A9-B40 phenotype in patients who manifested a strong in vitro proliferative response to PPD, whereas the HLA-B14-DR1 phenotype was increased in patients who exhibited a low proliferative response to this antigen.
Characterization of Epstein‐Barr viral strains in parotid gland saliva and peripheral blood of patients with primary Sjögren's syndrome and healthy EBV carriers (1993)

Increased Epstein-Barr virus (EBV) replication has been reported in the salivary and lacrimal glands in Sjögren's syndrome (SS). We studied whether or not certain EBV strains would occur preferentially in the peripheral blood and parotid gland saliva of 18 EBV-seropositive patients with primary Sjögren's syndrome (pSS) and 12 EBV-seropositive control persons. Transforming EBV was detected in the blood of 11 of 18 (61%) pSS patients and 9 of 12 controls (75%). Unexpectedly, neither transforming nor Raji-superinfecting EBV strains were detected in SS parotid saliva, whereas these EBV types were detected in control saliva in 7 and 8 cases, respectively (P < 0.001). Transforming EBV strains were further characterized by 'Ebno-typing,' i.e., analysis of the size spectrum of the viral antigens EBNA 1, 2, 3, and 6 in immunoblots of lymphoblastoid cell lines (LCL). Previous work has shown that a single EBV strain (Ebnotype) dominates the blood and oropharynx of healthy carriers and that unrelated individuals carry different EBV strains, reflecting the vast polymorphism of Ebnotypes in the general population. Two unexpected observations were made. First, an identical Ebnotype was detected in 4 unrelated individuals, i.e., in the blood of 1 pSS patient and in the saliva of 3 control persons. Second, carriage of 2 to 4 different Ebnotypes by a single individual was observed in 4 cases, i.e., in the blood of 1 pSS patient, and in the blood and saliva of 3 control persons.(ABSTRACT TRUNCATED AT 250 WORDS)
Commercial opportunities, versus government programs, will likely drive the future of laser communications (1996)

Historical applications for space-based, free-space laser communications have almost exclusively been borne out of government programs. While governments will remain the primary customer for research and exploratory applications, commercial demand is sure to drive the future of laser communications. It will either drive the industry to prosperity or out of business. This paper characterizes and postulates an end to lasercom's 'developmental era.' A paradigm shift is described which may lead the industry into its 'operational era.' Some future customers and their requirements, which will likely demand industry evolution, are identified. Characteristics of requisite change are descried. And finally, the implications of such change are postulated.

Efficient querying of distributed provenance stores (2010)

Current projects that automate the collection of provenance information use a centralized architecture for managing the resulting metadata - that is, provenance is gathered at remote hosts and submitted to a central provenance management service. In contrast, we are developing a completely decentralized system with each computer maintaining the authoritative repository of the provenance gathered on it. Our model has several advantages, such as scaling to large amounts of metadata generation, providing low-latency access to provenance metadata about local data, avoiding the need for synchronization with a central service after operating while disconnected from the network, and letting users retain control over their data provenance records. We describe the SPADE project's support for tracking data provenance in distributed environments, including how queries can be optimized with provenance sketches, pre-caching, and caching.
Laminin γ1 is critical for Schwann cell differentiation, axon myelination, and regeneration in the peripheral nerve (2003)

Laminins are heterotrimeric extracellular matrix proteins that regulate cell viability and function. Laminin-2, composed of alpha2, beta1, and gamma1 chains, is a major matrix component of the peripheral nervous system (PNS). To investigate the role of laminin in the PNS, we used the Cre-loxP system to disrupt the laminin gamma1 gene in Schwann cells. These mice have dramatically reduced expression of laminin gamma1 in Schwann cells, which results in a similar reduction in laminin alpha2 and beta1 chains. These mice exhibit motor defects which lead to hind leg paralysis and tremor. During development, Schwann cells that lack laminin gamma1 were present in peripheral nerves, and proliferated and underwent apoptosis similar to control mice. However, they were unable to differentiate and synthesize myelin proteins, and therefore unable to sort and myelinate axons. In mutant mice, after sciatic nerve crush, the axons showed impaired regeneration. These experiments demonstrate that laminin is an essential component for axon myelination and regeneration in the PNS.
The short arm of chromosome 11 is a "hot spot" for hypermethylation in human neoplasia. (1988)

Inactivation of normally expressed genes may play a role in the formation and/or progression of human cancers. Methylation of cytosine in DNA could potentially participate in such alterations of gene expression. Abnormalities in DNA methylation are a consistent feature of human neoplasms, and we now show that these include not only previously recognized widespread genomic hypomethylation, but also regional increases in gene methylation. A hot spot for abnormal methylation of C + G-rich areas has been detected on the short arm of chromosome 11 in an area known to harbor tumor suppressor genes. This change occurs consistently in common forms of human cancer and appears early during the transformation of cells with viruses including members of the human T-cell leukemia (HTLV) family. Furthermore, in one chromosome 11 gene examined, calcitonin, the increased methylation in somatic tumor cells coincides with the presence of an "inactive" chromatin pattern in the transcriptional regulatory area. The increased regional DNA methylation demonstrated may then participate in or mark chromosomal changes associated with gene inactivation events that are central to the genesis and/or progression of human cancers.
Purification and properties of DNA polymerase from <i>Bacillus caldotenax</i> (1992)

A thermostable DNA polymerase was prepared from Bacillus caldotenax by using a four-step chromatography procedure. The protein exists as a monomer of M(r) 94,000, has a pI of 4.9 and has no associated 3'-5' or 5'-3'-exonuclease activities or endonuclease activity. The temperature optimum of the enzyme was about 70 degrees C and the pH for maximum activity was about 7.5. The enzyme has an absolute requirement for a bivalent cation, and maximum activity was obtained at the unusually high concentration of 70 mM-MgCl2. Mg2+ could be replaced by MnCl2 or CoCl2, with decreased activity, at the lower optimal concentrations of 1 mM and 2.5 mM respectively. Enzyme activity was inhibited in the presence of 2',3'-dideoxy-TTP, arabinosyl-CTP and aphidicolin. Enzyme activity was stimulated with KCl concentrations of about 100 mM, and concentrations of univalent salts above about 150 mM inhibited activity. The enzyme could use activated calf thymus DNA, poly(dA).p(dT)10 or primed single-stranded phage M13 DNA as a template and maximum activity was obtained with poly(dA).p(dT)10. The enzyme was inactive on unprimed single-stranded DNA, double-stranded DNA and polyribonucleotide template/primer. The apparent Km values for individual dNTPs, determined with the other dNTPs at saturating concentrations, were 5.7 microM (dCTP), 6.3 microM (dATP, dGTP) and 6.4 microM (dTTP). The Km value for the overall incorporation of each dNTP from an equimolar mixture of all four dNTPs was 24.7 microM. The kcat. value was about 1.05 s-1. The kcat./Km value was 0.16-0.18 M-1.s-1 for individual dNTPs and 0.04 for the incorporation of an equimolar mixture of all four dNTPs. Some of the properties of the enzyme show it may be classified as an alpha-Type DNA polymerase.
The Coliform Index and Waterborne Disease (1996)

In the past decade there has been a rapid increase in waterborne outbreaks of disease associated with viral and protozoan agents, normally in drinking waters that were found to be microbially safe using the Coliform Index.For nearly a quarter of a century indicator organisms, in particular the coliform group, have been used to ensure the microbial
