Influence of TP53 gene alterations and c-erbB-2 expression on the response to treatment with doxorubicin in locally advanced breast cancer. (2001)

TP53 status [mutations, immunostaining, and loss of heterozygosity (LOH)], expression of c-erbB-2, bcl-2, and histological grading were correlated to the response to doxorubicin monotherapy (14 mg/m2) administered weekly to 90 patients with locally advanced breast cancer. Mutations in the TP53 gene, in particular those affecting or disrupting the loop domains L2 or L3 of the p53 protein, were associated with lack of response to chemotherapy (P = 0.063 for all mutations and P = 0.008 for mutations affecting L2/L3, respectively). Similarly, expression of c-erbB-2 (P = 0.041), a high histological grade (P = 0.023), and lack of expression of bcl-2 (P = 0.018) all predicted chemoresistance. No statistically significant association between either p53 immunostaining or TP53 LOH and response to therapy was recorded, despite the finding that both were associated with TP53 mutation status (p53 immunostaining, P < 0.001; LOH, P = 0.021). Lack of immunostaining for p53 despite mutation of the TP53 gene was particularly seen in tumors harboring nonsense mutations or deletions/splices (7 of 10 negative for staining compared with 4 of 16 with missense mutations). TP53 mutations (total/affecting L2/L3 domains) were associated with expression of c-erbB-2 (P < 0.001 for both), high histological grade (P = 0.001 and P = 0.025), and bcl-2 negativity (P = 0.003 and P = 0.002). TP53 mutations, histological grade, and expression of bcl-2 (but not LOH or c-erbB-2 expression) all predicted for relapse-free as well as breast cancer-specific survival in univariate analysis (Ps between <0.0001 and 0.0155), but only tumor grade was found to be predictive in multivariate analysis (P = 0.01 and P = 0.0007, respectively). Our data are consistent with the hypothesis that certain TP53 mutations predict for resistance to doxorubicin in breast cancer patients. However, the observation that the majority of patients with TP53 mutations affecting or disrupting the L2/L3 domains with LOH in addition (n = 12) obtained a partial response (n = 4) or stabilization of disease (n = 5) during chemotherapy suggests redundant mechanisms to compensate for loss of p53 function. Our findings are consistent with the hypothesis that other defects may act in concert with loss of p53 function, causing resistance to doxorubicin in breast cancers.
Lack of Hypocretin Attenuates Behavioral Changes Produced by Glutamatergic Activation of the Perifornical-Lateral Hypothalamic Area (2014)

The findings of this study are consistent with a hypothesis that synergistic interactions between hypocretin and glutamatergic mechanisms within the perifornical, dorsomedial, and lateral hypothalamic area are critical for maintaining behavioral arousal, especially arousal involving elevated muscle tone.
Consensus inference on mobile phone sensors for activity recognition (2016)

The pervasive use of wearable sensors in activity and health monitoring presents a huge potential for building novel data analysis and prediction frameworks. In particular, approaches that can harness data from a diverse set of low-cost sensors for recognition are needed. Many of the existing approaches rely heavily on elaborate feature engineering to build robust recognition systems, and their performance is often limited by the inaccuracies in the data. In this paper, we develop a novel two-stage recognition system that enables a systematic fusion of complementary information from multiple sensors in a linear graph embedding setting, while employing an ensemble classifier phase that leverages the discriminative power of different feature extraction strategies. Experimental results on a challenging dataset show that our framework greatly improves the recognition performance when compared to using any single sensor.
Azulene based metal–organic frameworks for strong adsorption of H 2 (2010)

Two Zn MOFs, MOF-645 and MOF-646, comprised of polarized 1,3-azulenedicarboxylate were synthesized. The guest free MOF-646 showed strong MOF-H(2) interactions (7.8-6.8 kJ mol(-1)), which revealed the significant impact of internally polarized azulene backbone to stabilized H(2) molecules in the framework.
On the McShane integrability (1996)

For a given separable space X which contains no copy of $C_0$ and a weakly compact T, we show that a Dunford integrable function $f : [a,b] \to X$ is intrinsically-separable valued if and only if f is McShane integrable. Also, for a given separable space X which contains no copy of $C_0$, a weakly compact T and a Dunford integrable function f we show that if there exists a sequence $(f_n)$ of McShane integrable functions from [a,b] to X such that for each $x^* \in X^*, x^*f_n \to x^*f$ a.e., then f is McShane integrable. Finally, let X contain no copy of $C_0$. If $f : [a,b] \to X$ is McShane integrable, then F is a countably additive on $\sum$.
Common Blood Flow Changes across Visual Tasks: II. Decreases in Cerebral Cortex (1997)

Nine previous positron emission tomography (PET) studies of human visual information processing were reanalyzed to determine the consistency across experiments of blood flow decreases during active tasks relative to passive viewing of the same stimulus array. Areas showing consistent decreases during active tasks included posterior cingulate/precuneous (Brodmann area, BA 31/7), left (BAS 40 and 39/19) and right (BA 40) inferior parietal cortex, left dorsolateral frontal cortex (BA S), left lateral inferior frontal cortex (BA 10/47), left inferior temporal gyrus @A 20), a strip of medial frontal regions running along a dorsal-ventral axis (BAs 8, 9, 10, and 32), and the right amygdala. Experiments involving language-related processes tended to show larger decreases than nonlanguage experiments. This trend mainly reflected blood flow increases at certain areas in the passive conditions of the language experiments (relative to a fixation control in which no task stimulus was present) and slight blood flow decreases in the passive conditions of the nonlanguage experiments. When the active tasks were referenced to the fixation condition, the overall size of blood flow decreases in language and nonlanguage tasks were the same, but differences were found across cortical areas. Decreases were more pronounced in the posterior cingulate/precuneous (BAS 31/7) and right inferior parietal cortex (BA 40) during language-related tasks and more pronounced in left inferior frontal cortex (BA 10/47) during nonlanguage tasks. Blood flow decreases did not generally show significant differences across the active task states within an experiment, but a verb-generation task produced larger decreases than a read task in right and left inferior parietal lobe (BA 40) and the posterior cingulate/precuneous (BA 31/7), while the read task produced larger decreases in left lateral inferior frontal cortex (BA 10/47). These effects mirrored those found between experiments in the language-nonlanguage comparison. Consistent active minus passive decreases may reflect decreased activity caused by active task processes that generalize over tasks or increased activity caused by passive task processes that are suspended during the active tasks. Increased activity during the passive condition might reflect ongoing processes, such as unconstrained verbally mediated thoughts and monitoring of the external environment, body, and emotional state.
THE EFFECTS OF A DUAL LANGUAGE READING PROGRAM ON THE READING ABILITY OF PUERTO RICAN STUDENTS (1982)

This study examines if a group of recently arrived Puerto Rican students (NAPR) will develop reading skills in English and Spanish at the same rate that‐Puerto Rican students (BIPR) had who participated in bilingual programs. The sample consisted of 70 ninth grade students divided into a treatment group (NAPR) and a comparison group (BIPR). The treatment in this study was time spent in reading. The results indicated that the recently arrived Puerto Rican students performed significantly better than did the comparison group (BIPR) in vocabulary and reading comprehension in both English and Spanish.
Molecular cloning of an insect pheromone‐binding protein (1989)

Clones coding for the pheromone binding protein precursor have been selected from a cDNA library derived from antennae of the male moth, Antheraea polyphemus. The deduced protein sequence consists of a signal peptide of 20 amino acid residues and a mature binding protein of 142 amino acid residues. RNA blot hybridization indicated that the mRNA is selectively expressed in the antennae of the male moth.
Fabrication of engineered M13 bacteriophages into liquid crystalline films and fibers for directional growth and encapsulation of fibroblasts (2010)

We report on a novel method to utilize genetically engineered M13 phages as functional nano building blocks that can form structurally aligned film and fiber matrices for tissue engineering scaffolds. Two- and three-dimensional directionally aligned long range ordered structures were constructed using shearing and polyionic complexation with cationic polymers. Further we have demonstrated that aligned phage-based tissue engineering materials can guide and stimulate the growth of the target fibroblasts. Our phage-based tissue engineering scaffolds can be used for providing micro and macroscopic control of cell behaviors.

Amylopectin and Intermediate Materials in Starches from Mutant Genotypes of the Oh43 Inbred Line. (1993)

Amylopectin (AP) and intermediate materials (IM) from five endosperm mutant genotypes in a common Oh43 inbred line were isolated and examined by gel-permeation chromatography, iodine affinity, blue value (BV), and viscosity. The chain-length distributions of AP and IM were determined using an enzymatic- chromatographic method. The degrees of branching in AP and IM decreased when the amylose-extender (ae) gene was present. The dull-1 (du1) gene produced AP and IM with the highest degrees of branching among the samples. The ae starch had a significantly (P less than 0.01) longer peak average chain length (CL) of the long-B chains in the IM fraction (177 glucose units) than did the AP faction (73 glucose units) or the other starches (37-56 glucose units). The higher iodine affinity in ae starch of the IM (6.1) compared with that of the AP (2.8) supported the idea that the IM had a longer CL than did the AP. There were no significant differences in the peak CL of A or B chains in AP and IM fractions of brittle-1 (bt1), du1, ae bt1, and ae du1 starches. The IM of ae and ae du1 starches had higher BV than did the AP fractions; however, the IM of du1 and ae bt1 had lower BV than did the AP fractions. The limiting viscosity number and gel- permeation chromatography results indicated that the AP and IM fractions of bt1 and du1 starches possessed more branching and larger hydrodynamic volume properties than those of the ae, ae bt1, and ae du1 starches. The present study demonstrated that genetic background affects the CL of starch branches, degree of branching, and iodine binding properties of starches.
Salmonella induces the formation of filamentous structures containing lysosomal membrane glycoproteins in epithelial cells. (1993)

Salmonella species invade and replicate within epithelial cells in membrane-bound vacuoles. In this report we show that upon infection of HeLa epithelial cells, Salmonella typhimurium residues in vacuoles that contain lysosomal membrane glycoproteins (lgps). Four to six hours after invasion, intracellular bacteria induce the formation of stable filamentous structures containing lgps that are connected to the bacteria-containing vacuoles. Formation of these lgp-rich structures requires viable intracellular bacteria and is blocked by inhibitors of vacuolar acidification. These structures are not present in uninfected cells or in cells infected with another invasive bacteria, Yersinia enterocolitica. Tracers added to the extracellular medium are not delivered to the Salmonella-induced filaments, suggesting that these structures are different from previously described tubular lysosomes. Initiation of intracellular bacterial replication correlates with formation of these lgp-containing filaments. Certain avirulent Salmonella mutants that are defective for intracellular replication fail to induce formation of these structures. These observations suggest that Salmonella-induced filaments containing lgps are linked to intracellular bacterial replication.
Differentiation and proliferation of hematopoietic stem cells (1993)

Available evidence indicates that qualitative changes in hematopoietic stem cells and progenitors, such as the decision of stem cells to self-renew or differentiate, or selection of lineage potentials by the multipotential progenitors during differentiation (commitment), are intrinsic properties of the progenitors and are stochastic in nature. In-contrast, proliferative kinetics of the progenitors, namely survival and expansion of the progenitors, appear to be controlled by a number of interacting cytokines. While proliferation and maturation of committed progenitors is controlled by late-acting lineage-specific factors such as Ep, M-CSF, G-CSF, and IL-5, progenitors at earlier stages of development are controlled by a group of several overlapping cytokines. IL-3, GM-CSF, and IL-4 regulate proliferation of multipotential progenitors only after they exit from G0 and begin active cell proliferation. Triggering of cycling by dormant primitive progenitors and maintenance of B-cell potential of the primitive progenitors appears to require interactions of early acting cytokines including IL-6, G-CSF, IL-11, IL-12, LIF, and SF. Currently, this simple model fits our understanding of the interactions of growth factors with hematopoietic progenitors. Naturally the model risks oversimplification of a very complex process. However, because the model is testable, it will hopefully challenge investigators to design new experiments to examine its validity.
Sex Differences in Antidepressant Response in Recent Antidepressant Clinical Trials (2005)

Some previous reports suggest that women respond differently than men to antidepressant treatment. Much of this literature compares men and women's response to tricyclics to that of newer antidepressants (SSRIs, SNRI), or only examines one particular antidepressant. This study compares men and women's responses to 6 newer antidepressants. A total of 15 randomized, placebo-controlled trials that included 323 depressed patients were examined for sex differences in antidepressant treatment response. Women had a significantly greater response than men to SSRI antidepressants. A similar trend was seen for those assigned to an SNRI antidepressant, although not to the same extent as with SSRI antidepressants. Although these gender differences in treatment response are not large enough to suggest that gender should guide the clinical use of SSRI and SNRI antidepressants, the results do have implications for the design and interpretation of antidepressant clinical trials. These findings also raise the possibility that antidepressants may work somewhat differently in men and women.

Enzyme-linked immunosorbent assay for the detection and the semi-quantitative determination of taxane diterpenoids related to taxol in Taxus sp. and tissue cultures. (1991)

An ELISA-assay for the detection and the semi-quantitative determination of taxane diterpenoids structurally related to taxol found in Taxus sp. has been developed. The antiserum was raised in rabbits using a 2'-succinyltaxol-bovine serum albumin conjugate as immunogen. The working range of the assay was from 1 to 100 ng of taxol. In order to improve the production of taxol, preliminary experiments have been performed on crude extracts of several Taxus sp.; the results indicate that the present immunoassay is an useful tool for the rapid screening of species, varieties or individual plants out of a large population as well as for tissue cultures analysis.
Ntk: a Csk-related protein-tyrosine kinase expressed in brain and T lymphocytes. (1994)

The activity of Src-related protein-tyrosine kinases is repressed by the phosphorylation of a conserved carboxyl-terminal tyrosine by another cytoplasmic protein-tyrosine kinase termed p50csk. In this study, we characterize Ntk, a protein-tyrosine kinase bearing striking similarities to p50csk. Like p50csk, Ntk possesses Src homology 3 and Src homology 2 domains and lacks the consensus tyrosine phosphorylation and myristoylation sites found in members of the Src family. Expression of ntk transcripts was maximal in brain, and was observed at significant levels in thymus and spleen. ntk RNA levels were dramatically reduced upon mitogenic stimulation of normal T lymphocytes and were minimal in transformed T-cell populations. Firm evidence that Ntk is a Csk-related enzyme was provided by the observation that it phosphorylated a Src-related polypeptide on the inhibitory carboxyl-terminal tyrosine. These findings indicate that Ntk is a Csk-related enzyme that may play an inhibitory role in the control of T-cell proliferation.
Effects of peptide dimerization on pore formation: Antiparallel disulfide-dimerized magainin 2 analogue (2001)

To elucidate the effects of peptide dimerization on pore formation by magainin 2 (MG2), a covalently linked antiparallel dimer of the MG2 analogue [(F5Y, L6C, F16W, I20C-MG2)(2): II] was synthesized based on the dimer structure revealed by our NMR study. The interactions of the dimer with lipid bilayers were investigated by CD and fluorescence in comparison with a monomer analogue (F5Y, F16W-MG2: I). Similar to I, II was found to form a peptide-lipid supramolecular complex pore accompanied with lipid flip-flop and peptide translocation. The pore formed by II was characterized by a slightly larger pore diameter and a threefold longer lifetime than that of I, although the pore formation rate of the dimer was lower than that of the monomer. The coexistence of the dimer and the monomer exhibited slight but significant synergism in membrane permeabilization, which was maximal at a monomer/dimer ratio of 3. Therefore, we concluded that a pentameric pore composed of one pore-stabilizing dimer and three monomers maximized the overall leakage activity in keeping with our kinetic prediction.
Circulating Tumor Cells at Each Follow-up Time Point during Therapy of Metastatic Breast Cancer Patients Predict Progression-Free and Overall Survival (2006)

Detection of elevated CTCs at any time during therapy is an accurate indication of subsequent rapid disease progression and mortality for MBC patients.
Effects of Corticosteroids on Systemic Inflammation in Chronic Obstructive Pulmonary Disease (2005)

Patients with chronic obstructive pulmonary disease (COPD) are predisposed to atherosclerosis and coronary artery disease, but the underlying mechanisms are unclear. Although there is wide acceptance that atherosclerosis is related to systemic inflammation, the cause(s) and mechanism(s) of pulmonary inflammation in stable COPD remain unknown. Infectious (bacterial and viral) as well as noninfectious agents can cause acute exacerbations in COPD, and they intensify local and systemic inflammation. Although it is not known how systemic inflammation develops in stable COPD, there is good evidence to suggest that it occurs and that the intensity of systemic inflammation is linked to the severity of airflow obstruction. We postulate that systemic inflammation provides the linkage between COPD and atherosclerosis. Inhaled corticosteroids have been shown to improve health outcomes in COPD, but the mechanism by which this occurs is a pivotal and challenging question that has yet to be answered. To prove the concept that inhaled corticosteroids could suppress systemic inflammation (as exemplified by serum C-reactive protein [CRP] levels), a double-blind, placebo-controlled clinical trial was conducted in a group of patients with mild to moderate COPD. We found that withdrawal of inhaled corticosteroids increased serum CRP levels, and that reintroduction of inhaled fluticasone could suppress CRP levels.
Nuclear Morphometry for Prediction of Metastatic Potential in Early Squamous Cell Carcinoma of the Floor of the Mouth (1992)

Quantitative morphometric analyses of the nuclear shape have been successfully used with prostatic carcinoma to predict tumor metastatic potential and provide the most sensitive indicator of tumor aggressiveness in the individual case. We have studied the nuclear morphometric characteristics of 22 patients with T1 and T2 squamous cell carcinoma of the floor of the mouth to see if a correlation existed between lack of nuclear roundness and presence of cervical metastatic disease. A significant difference was identified between the morphology of cancer cell nuclei and normal squamous epithelium. Nuclear morphology could not be used to distinguish between patients with cervical node-negative and node-positive disease. Some patients both with and without cervical metastases who are long-term survivors had nuclear roundness scores in the highest range, reflecting greatest variation from normal.
Wnt canonical pathway restricts graded Shh/Gli patterning activity through the regulation of Gli3 expression (2007)

Dorsoventral patterning of the vertebrate nervous system is achieved by the combined activity of morphogenetic signals secreted from dorsal and ventral signalling centres. The Shh/Gli pathway plays a major role in patterning the ventral neural tube; however, the molecular mechanisms that limit target gene responses to specific progenitor domains remain unclear. Here, we show that Wnt1/Wnt3a, by signalling through the canonical beta-catenin/Tcf pathway, control expression of dorsal genes and suppression of the ventral programme, and that this role in DV patterning depends on Gli activity. Additionally, we show that Gli3 expression is controlled by Wnt activity. Identification and characterization of highly conserved non-coding DNA regions around the human Gli3 gene revealed the presence of transcriptionally active Tcf-binding sequences. These indicated that dorsal Gli3 expression might be directly regulated by canonical Wnt activity. In turn, Gli3, by acting as a transcriptional repressor, restricted graded Shh/Gli ventral activity to properly pattern the spinal cord.

Angiotensin-(1-7) improves oxygenation, while reducing cellular infiltrate and fibrosis in experimental Acute Respiratory Distress Syndrome (2015)

Angiotensin-(1-7), decreased the severity of acute lung injury and inflammation induced by combined acid aspiration and high stretch ventilation. Furthermore, continuous infusion of Ang-(1-7) reduced lung fibrosis 2 weeks following acid aspiration injury. These results call for further research on Ang-(1-7) as possible therapy for ARDS.
