Growth hormone treatment of adults withgrowth hormone deficiency: results of a 13‐month placebo controlled cross‐over study (1992)

GH alters the body composition of growth hormone deficient adults and leads to improved exercise capacity; alkaline phosphatase activity increases but without a change in spinal bone density, and carbohydrate tolerance remains unaltered.
The Transmogrifier C hardware description language and compiler for FPGAs (2002)

The Transmogrifier C hardware description language is almost identical to the C programming language, making it attractive to the large community of C-language programmers. This paper describes the semantics of the language and presents a Transmogrifier C compiler that targets the Xilinx 4000 FPGA. The compiler is operational and has produced several working circuits, including a graphics display driver.

We conclude that higher adherence to the MeDi is associated with a reduction in risk for AD.
Noninvasive Blood Glucose Monitoring (1997)

The concentration of glucose in the blood may soon be measured noninvasively, without puncturing the finger to obtain a drop of blood. Current prototype devices for this purpose require greater accuracy and miniaturization to be commercially viable. No such device has been approved for marketing by the U.S. Food and Drug Administration. The technology used for noninvasive blood glucose monitoring involves either radiation or fluid extraction. With radiation technology, an energy beam is 1) applied to the body, 2) modified proportionate to the concentration of glucose in the blood, and 3) measured. The blood glucose concentration is then calculated. With fluid extraction technology, a body fluid containing glucose in a concentration proportionate to the blood glucose concentration is extracted and measured. The blood glucose concentration is then calculated. The most promising technologies are 1) near-infrared light spectroscopy, 2) far-infrared radiation spectroscopy, 3) radio wave impedance, 4) optical rotation of polarized light, 5) fluid extraction from skin, and 6) interstitial fluid harvesting. Each method has features predictive of commercial viability, as well as technical problems to overcome.
Aldose Reductase Induced by Hyperosmotic Stress Mediates Cardiomyocyte Apoptosis (2003)

Cells adapt to hyperosmotic conditions by several mechanisms, including accumulation of sorbitol via induction of the polyol pathway. Failure to adapt to osmotic stress can result in apoptotic cell death. In the present study, we assessed the role of aldose reductase, the key enzyme of the polyol pathway, in cardiac myocyte apoptosis. Hyperosmotic stress, elicited by exposure of cultured rat cardiac myocytes to the nonpermeant solutes sorbitol and mannitol, caused identical cell shrinkage and adaptive hexose uptake stimulation. In contrast, only sorbitol induced the polyol pathway and triggered stress pathways as well as apoptosis-related signaling events. Sorbitol resulted in activation of the extracellular signal-regulated kinase (ERK), p54 c-Jun N-terminal kinase (JNK), and protein kinase B. Furthermore, sorbitol treatment resulting in induction and activation of aldose reductase, decreased expression of the antiapoptotic protein Bcl-xL, increased DNA fragmentation, and glutathione depletion. Apoptosis was attenuated by aldose reductase inhibition with zopolrestat and also by glutathione replenishment with N-acetylcysteine. In conclusion, our data show that hypertonic shrinkage of cardiac myocytes alone is not sufficient to induce cardiac myocyte apoptosis. Hyperosmolarity-induced cell death is sensitive to the nature of the osmolyte and requires induction of aldose reductase as well as a decrease in intracellular glutathione levels.

Depressed T‐Cell Interferon‐γ Responses in Pulmonary Tuberculosis: Analysis of Underlying Mechanisms and Modulation with Therapy (1999)

Immunological and clinical profiles were evaluated in 2 groups: human immunodeficiency virus (HIV)-uninfected and HIV-infected patients, with newly diagnosed pulmonary tuberculosis (TB), and tuberculin-skin-test-reactive healthy control subjects. HIV-uninfected patients with TB were also followed up longitudinally during and after chemotherapy. At the time of diagnosis, purified protein derivative (PPD)-stimulated production of interferon (IFN)-gamma by peripheral blood mononuclear cells from TB patients was depressed, compared with that of healthy control subjects, whereas levels of transforming growth factor (TGF)-beta and interleukin (IL)-10 were increased. In longitudinal studies, PPD stimulated production of IL-10 and TGF-beta returned to baseline by 3 months, whereas IFN-gamma production remained depressed for at least 12 months. These data indicate that the immunosuppression of TB is not only immediate and apparently dependent (at least in part) on immunosuppressive cytokines early during the course of Mycobacterium TB infection but is also long lasting, presumably relating to a primary abnormality in T-cell function.
From Optogenetic Technologies to Neuromodulation Therapies (2013)

Optogenetics field of optogenetics has provided new insight into neuronal communication and complex brain function. Now, scientists eagerly anticipate clinical application of this technology, with the hope that it will help improve treatments for various neurological disorders. However, the translational hurdles are high. In this Perspective, we highlight the technical, practical, and regulatory hurdles that lie ahead along the path towards making optogenetic neuromodulation therapies a reality in the clinic.
Nonclassical Active Site for Enhanced Gas Sorption in Porous Coordination Polymer (2010)

Gas sorption experiments and grand canonical Monte Carlo simulations for two isostructural microporous metal azolate frameworks show that even partially exposed uncoordinated nitrogens can effectively increase gas binding affinity and overcome the pore size confinement effect.
Regulation of Trabecular Meshwork Contractility (2000)

Ample evidence supports the theory that trabecular meshwork possesses smooth-muscle-like properties. Trabecular meshwork cells express a large number of transporters, channels and receptors, many of which are known to regulate smooth-muscle contractility. It has been shown that trabecular meshwork can be induced to contract and relax in response to pharmacological agents. In the model of the bovine eye, confirmed in some cases by experiments on primates, agents that contract trabecular meshwork reduce outflow. On the cellular level, this is coupled with depolarization and a rise in intracellular calcium. Relaxation of trabecular meshwork, on the other hand, appears to be coupled to a stimulation of the maxi-K channel, inducing hyperpolarization and a closure of L-type calcium channels. No significant differences between cells from a human and a bovine source emerged, either in classical measurements of membrane voltage, in measurements of intracellular calcium or patch-clamp experiments. Thus, pharmacological agents that relax trabecular meshwork seem promising candidates for further research - the ultimate goal being an improvement of glaucoma therapy in humans.
Possible Novel Mechanism for Bitter Taste Mediated Through cGMP (1999)

Taste is the least understood among sensory systems, and bitter taste mechanisms pose a special challenge because they are elicited by a large variety of compounds. We studied bitter taste signal transduction with the quench-flow method and monitored the rapid kinetics of the second messenger guanosine 3',5'-cyclic monophosphate (cGMP) production and degradation in mouse taste tissue. In response to the bitter stimulants, caffeine and theophylline but not strychnine or denatonium cGMP levels demonstrated a rapid and transient increase that peaked at 50 ms and gradually declined throughout the following 4.5 s. The theophylline- and caffeine-induced effect was rapid, transient, concentration dependent and gustatory tissue-specific. The effect could be partially suppressed in the presence of the soluble guanylyl cyclase (GC) inhibitor 10 microM ODQ and 30 microM methylene blue but not 50 microM LY 83583 and boosted by nitric oxide donors 25 microM NOR-3 or 100 microM sodium nitroprusside. The proposed mechanism for this novel cGMP-mediated bitter taste signal transduction is cGMP production partially by the soluble GC and caffeine-induced inhibition of one or several phosphodiesterases.
Assessment of the reproducibility of the indirect ultrasound method of measuring diaphragm mobility (2013)

The aim of this study was to assess the reproducibility of the ultrasound (US) measurement of craniocaudal displacement of the left branch of the portal vein as an indirect method of measuring right hemidiaphragm mobility in healthy young adults. Forty-one healthy participants were selected, ranging from 20 to 30 years of age. The US tests were conducted and interpreted by two observers (A and B) on two separate occasions (Test 1 and Test 2). Intra-observer and interobserver reproducibility and repeatability of US measurements were determined by the intraclass correlation coefficient (ICC[2,1] ) using a 95% confidence interval (CI). Interobserver reproducibility assessment showed 'high correlation' for Test 1 and Test 2 (ICC[2,1] = 0·83, 95% CI = 0·70-0·91, and ICC[2,1] = 0·79, 95% CI = 0·61-0·89, respectively). Intra-observer reproducibility assessment showed 'moderate correlation' for observer A (ICC[2,1] = 0·69, 95% CI = 0·45-0·84) and for observer B (ICC[2,1] = 0·65, 95% CI = 0·39-0·81). Repeatability assessment showed 'high correlation' for all tests performed (ICC[2,1] = 0·86, 0·80, 0·74, 0·79, P<0·001). In conclusion, US measurement of craniocaudal displacement of the left branch of the portal vein is a reproducible method of measuring right hemidiaphragm mobility in healthy young adults.
Patient beam positioning system using CT images (1982)

If treatment planning is done using the CT scanner's computer immediately the images are produced and before the patient's position is changed, then what is required is a mechanism to transfer back to the patient the resulting beam positioning information. A system that does this is described. The system consists of a central processing unit (PDP-LSI-11), main memories, peripheral memories (DISK and MT), and an image display unit.

The dopamine D3 receptor plays an essential role in alcohol‐seeking and relapse (2006)

Our study aimed to identify new candidate genes, which might be involved in alcohol craving and relapse. To find changes in gene expression after long-term alcohol consumption, we studied gene expression profiles in the striatal dopamine system by using DNA microarrays of two different alcohol-preferring rat lines (HAD and P). Our data revealed an up-regulation of the dopamine D3 receptor (D3R) after 1 yr of voluntary alcohol consumption in the striatum of alcohol preferring rats that was confirmed by qRT-polymerase chain reaction. This finding was further supported by the finding of up-regulated striatal D3R mRNA in nonselected Wistar rats after long-term alcohol consumption when compared with age-matched control animals. We further examined the role of the D3R in mediating alcohol relapse behavior using the alcohol deprivation effect (ADE) model in long-term alcohol drinking Wistar rats and the model of cue-induced reinstatement of alcohol-seeking behavior using the selective D3R antagonist SB-277011-A (0, 1, 3, and 10 mg/kg) and the partial agonist BP 897 (0, 0.1, 1, and 3 mg/kg). Both treatments caused a dose-dependent reduction of relapse-like drinking in the ADE model as well as a decrease in cue-induced ethanol-seeking behavior. We conclude that long-term alcohol consumption leads to an up-regulation of the dopamine D3R that may contribute to alcohol-seeking and relapse. We therefore suggest that selective antagonists of this pharmacological target provide a specific treatment approach to reduce alcohol craving and relapse behavior.
Preservation of Nucleic Acids for Polymerase Chain Reaction After Prolonged Storage at Room Temperature (1998)

A guanidinium isothiocyanate (GITC) lysis solution was evaluated for its efficacy in preserving nucleic acids for subsequent analysis after prolonged storage at room temperature. Aliquots of thyroid crude cell lysates were stored at 22 degrees C for 8 weeks in the GITC solution. Crude cell lysates stored for 2 weeks in the GITC solution consistently provided adequate RNA and DNA for reverse transcriptase-polymerase chain reaction (RT-PCR) and PCR, respectively, of beta 2-microglobulin, thyroid stimulating hormone receptor (TSHR), and thyroglobulin. Interestingly, the thyroglobulin and TSHR messages from thyroid fine needle aspirate samples were detected by RT-PCR only when stored at room temperature for less than 1 week, whereas the RT-PCR product for beta 2-microglobulin was detectable in 95% of the samples at 3 months. In addition, thyroglobulin DNA was amplified by PCR in nearly all samples stored at 22 degrees C for 2 months. These data suggest that GITC solutions can be used to preserve nucleic acids in most circumstance until transported to laboratories equipped and staffed with appropriate resources.
Volatile components of ginger flowers (Hedychium coronarium koenig) (1991)

Abstract Volatile components of the ginger flower ( Hedychium coronarium Koenig) were concentrated by solvent extraction and further simultaneous distillation and extraction (SDE). The essential oil was fractionated by column chromatography and analysed with GC and GC‐MS, and 131 compounds were identified. The ginger flower has a diffusive, sweet, spicy and floral scent and linalol, methyl jasmonate, eugenols, cis ‐jasmone, β‐ionone and lactones were found to make a major contribution to the odour of this flower.

Distribution of Protein A on the Surface of Staphylococcus aureus (2007)

Surface proteins of Staphylococcus aureus fulfill many important roles during the pathogenesis of human infections and are anchored to the cell wall envelope by sortases. Although the chemical linkage of proteins to cell wall cross bridges is known, the mechanisms whereby polypeptides are distributed on the staphylococcal surface have not been revealed. We show here that protein A, the ligand of immunoglobulin, is unevenly distributed over the staphylococcal surface. Upon removal with trypsin, newly synthesized polypeptide is deposited at two to four discrete foci. During subsequent growth, protein A appears to be slowly distributed from these sites. When viewed through multiple focal planes by laser scanning microscopy, protein A foci are arranged in a circle surrounding the bacterial cell. This pattern of distribution requires the LPXTG sorting signal of protein A as well as sortase A, the transpeptidase that anchors polypeptides to cell wall cross bridges. A model is presented whereby protein A deposition at discrete sites coupled with cell wall synthesis enables distribution of protein A on the staphylococcal surface.

Circulating B-Cell Chronic Lymphocytic Leukemia Cells Display Impaired Migration to Lymph Nodes and Bone Marrow (2009)

Homing to secondary lymphoid organs and bone marrow (BM) is a central aspect of leukemic pathophysiology. We investigated the roles of the two major lymphocyte integrins LFA-1 and VLA-4 on B-cell chronic lymphocytic leukemia (CLL) cells in these processes. We found that the majority of CLL cells expressed significantly reduced LFA-1 due to low beta2 integrin transcripts. VLA-4 expression was heterogeneous but underwent rapid activation by the BM chemokine CXCL12. CLL cells failed to transmigrate across VCAM-1-expressing, ICAM-1-expressing, and CXCL12-expressing endothelium, whereas when LFA-1 expression was regained in subsets of CLL cells, these lymphocytes rapidly transmigrated the endothelium. Furthermore, when injected into tail veins of immunodeficient mice, normal B cells rapidly homed to lymph nodes (LN) in a LFA-1-dependent manner, whereas CLL cells did not. Nevertheless, only residual CLL subsets could reenter BM, whereas both normal and CLL cells homed to the mice spleen in an LFA-1-independent and VLA-4-independent manner. Our results suggest that CLL cells have a reduced capacity to adhere and transmigrate through multiple vascular endothelial beds and poorly home to lymphoid organs other than spleen. Integrin blocking could thus be an efficient strategy to prevent circulating CLL cells from reaching prosurvival niches in LNs and BM but not in spleen.
Prostate cancer stromal cells and LNCaP cells coordinately activate the androgen receptor through synthesis of testosterone and dihydrotestosterone from dehydroepiandrosterone (2009)

One of the mechanisms through which advanced prostate cancer (PCa) usually relapses after androgen deprivation therapy (ADT) is the adaptation to residual androgens in PCa tissue. It has been observed that androgen biosynthesis in PCa tissue plays an important role in this adaptation. In the present study, we investigated how stromal cells affect adrenal androgen dehydroepiandrosterone (DHEA) metabolism in androgen-sensitive PCa LNCaP cells. DHEA alone had little effect on prostate-specific antigen (PSA) promoter activity and the proliferation of LNCaP cells. However, the addition of prostate stromal cells or PCa-derived stromal cells (PCaSC) increased DHEA-induced PSA promoter activity via androgen receptor activation in the LNCaP cells. Moreover, PCaSC stimulated the proliferation of LNCaP cells under physiological concentrations of DHEA. Biosynthesis of testosterone or dihydrotestosterone from DHEA in stromal cells and LNCaP cells was involved in this stimulation of LNCaP cell proliferation. Androgen biosynthesis from DHEA depended upon the activity of various steroidogenic enzymes present in stromal cells. Finally, the dual 5alpha-reductase inhibitor dutasteride appears to function not only as a 5alpha-reductase inhibitor but also as a 3beta-hydroxysteroid dehydrogenase inhibitor in LNCaP cells. Taken together, this coculture assay system provides new insights of coordinate androgen biosynthesis under the microenvironment of PCa cells before and after ADT, and offers a model system for the identification of important steroidogenic enzymes involved in PCa progression and for the development of the corresponding inhibitors of androgen biosynthesis.
Eicosapentaenoic and docosahexaenoic acids production by and okara-utilizing potential of thraustochytrids (2001)

Nine thraustochytrid strains isolated from subtropical mangroves were screened for their eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) production potential in a glucose yeast extract medium. Their ability to utilize okara (soymilk residue) for growth and EPA and DHA production was also evaluated. EPA yield was low in most strains, while DHA level was high on glucose yeast extract medium, producing 28.1-41.1% of total fatty acids, for all strains, with the exception of Ulkenia sp. KF13. The DHA yield of Schizochytrium mangrovei strains ranged from 747.7 to 2778.9 mg/l after 52 h of fermentation at 25 degrees C. All strains utilized okara as a substrate for growth, but DHA yield was lower when compared with fermentation in a glucose yeast extract medium.
