First Pharmacological Therapy for Hypoactive Sexual Desire Disorder in Premenopausal Women (2015)

Flibanserin is effective in the treatment of HSDD. Flibanserin should be administered at bedtime to limit the risk for hypotension/syncope, accidental injury, and central nervous system (CNS) depression. Concomitant alcohol use contributes to significant CNS depression and hypotension/syncope with flibanserin and should be avoided according to the boxed warning. Careful patient assessment prior to the diagnosis of HSDD and the use of flibanserin is needed for safe use. Prescribing guidelines recommend discontinuing flibanserin at 8 weeks in the absence of benefit. Sexual dysfunction should be addressed in a patient-specific manner. Providers should exercise shared decision making in prescribing flibanserin for HSDD and discuss flibanserin's benefits and alternative options.
Ventriculocoronary artery bypass (VCAB), a novel approach to myocardial revascularization. (2000)

These preliminary studies show the promise of perfusing ischemic myocardium with systolic flow. Patency of the transmyocardial titanium conduit was excellent at 2 weeks and warrants longer duration studies.
Raman spectroscopy for noninvasive glucose measurements (2005)

We report the first successful study of the use of Raman spectroscopy for quantitative, noninvasive ("transcutaneous") measurement of blood analytes, using glucose as an example. As an initial evaluation of the ability of Raman spectroscopy to measure glucose transcutaneously, we studied 17 healthy human subjects whose blood glucose levels were elevated over a period of 2-3 h using a standard glucose tolerance test protocol. During the test, 461 Raman spectra were collected transcutaneously along with glucose reference values provided by standard capillary blood analysis. A partial least squares calibration was created from the data from each subject and validated using leave-one-out cross validation. The mean absolute errors for each subject were 7.8%+/-1.8% (mean+/-std) with R2 values of 0.83+/-0.10. We provide spectral evidence that the glucose spectrum is an important part of the calibrations by analysis of the calibration regression vectors.
Genetic Data Analysis: Methods for Discrete Population Genetic Data. (1991)

The interpretation of discrete genetic data lies at the heart of population and evolutionary genetics, yet basic statistics courses and texts generally concentrate on continuous variables. In Genetic Data Analysis a full account of the methodology appropriate for count data is presented. Starting with the basic idea of estimating gene frequencies, and proceeding through a wide range of topics to building phyilogenetic trees, the book contains the tools for analyzing genetic data on morphological characters, isozyme frequencies, restriction fragment patterns, and DNA sequences. Throughout the book, the importance of clarifying the sampling frame is stressed. For example, if conclusions are to be drawn about a single population, then only statistical sampling needs to be incorporated into expressions for variances of genetic parameter estimates. If conclusions are to be made on a wider basis, perhaps about a whole species, then the genetical sampling between generations that can cause local populations to differ must also be accommodated. This distinction is becoming increasingly important in the analysis of DNA sequence data, as the ability increases to generate multiple sequences of a particular region.
Toward the development of a neural interface for lower limb prosthesis control (2009)

Lower limb amputees form a large portion of the amputee population; however, current lower limb prostheses do not meet the needs of patients with high-level amputations who need to perform multi-joint coordinated movements. A critical missing element is an intuitive neural interface from which user intent can be determined. Surface EMG has been used as control source for upper limb prostheses for many years; for lower limb activities, however, the EMG is non-stationary and a new control strategy is required. This paper describes the work completed to date in developing a novel lower limb neural interface.

A new autologous keratinocyte dressing treatment for non‐healing diabetic neuropathic foot ulcers (2004)

TranCell delivery of autologous cells is a promising treatment for chronic diabetic foot ulcers with no side-effects and no recurrence in the healed ulcers.
The relationship between synthetic and editing functions of the active site of an aminoacyl-tRNA synthetase. (1993)

We have analyzed, by site-directed mutagenesis, the molecular basis of the editing function and its relation to the synthetic function of Escherichia coli methionyl-tRNA synthetase. The data obtained fit a model of the active site that partitions an amino acid substrate between synthetic and editing pathways. Hydrophobic and hydrogen bonding interactions direct the cognate substrate methionine through the synthetic pathway and prevent it from entering the editing pathway. Two hydrophobic interactions are proposed: between the side chain of Trp-305 and a methyl group of methionine and between the benzene ring of Tyr-15 and the beta- and gamma-CH2 groups of the substrate. An essential hydrogen bond forms between the OH of Tyr-15 and an electron pair of the sulfur atom of methionine. Consistent with these functions, side chains of Trp-305 and Tyr-15 are localized on opposite sides of the cavity forming a putative methionine binding pocket that is observed in the three-dimensional crystallographic structure of methionyl-tRNA synthetase. Enzymes W305A, Y15A, and Y15F have diminished ability to discriminate against homocysteine in the synthetic reaction, compared to the wild-type enzyme. At the same time, mutant enzymes have lost the ability to discriminate against methionine in the editing reaction and edited Met-AMP to a similar extent as Hcy-AMP. Interactions of residues Arg-233 and Asp-52 of methionyl-tRNA synthetase with the carboxyl and amino groups, respectively, of the substrate, which are essential for the synthetic function, were also essential for the editing function of the enzyme. Deacylation of Met-tRNA to S-methylhomocysteine thiolactone catalyzed by W305A, Y15A, and Y15F mutant enzymes was only slightly impaired relative to the wild-type enzyme. However, enzymes R233Q, R233A, and D52A did not deacylate Met-tRNA. The model also explains why the noncognate homocysteine is edited by methionyl-tRNA synthetase.
Sugar‐Lectin Interactions: How Does Wheat‐Germ Agglutinin Bind Sialoglycoconjugates? (1980)

The specific binding of N-acetylneuraminic acid to wheat-germ agglutinin is based on configuration similarities between N-acetylneuraminic acid and N-acetylglucosamine. The N-acetamido group and an adjacent hydroxyl group, both in an equatorial position are shown to be the main determinants. The N-acetylneuraminic acid--wheat-germ agglutinin interaction is increased by the removal of the last two carbons C8 and C9. The interaction between wheat-germ agglutinin and glycoconjugates containing N-acetylneuraminic acid is shown to be dependent on a charge effect and on an avidity effect. Succinylated wheat-germ agglutinin which is negatively charged at physiological pH, in contrast with wheat-germ agglutinin which is positively charged, does not bind cell surface glycoconjugates containing N-acetylneuraminic acid but does bind cell surface glycoconjugates containing N-acetylglucosamine. The use of wheat-germ agglutinin and of succinylated wheat-germ agglutinin leads to the determination of the number of cell surface receptors containing N-acetylneuraminic acid.
Regulation of D‐3 phosphoinositides during T cell activation via the T cell antigen receptor/CD3 complex and CD2 antigens (1992)

An immediate consequence of T cell activation via the T cell receptor (TcR)/CD3 complex and CD2 antigen is the hydrolysis of phosphatidylinositol-(4,5)-bisphosphate and the generation of inositol-(1,4,5)-trisphosphate and diacylglycerol which then regulate intracellular calcium and protein kinase C. Changes in cellular levels of phosphoinositides phosphorylated on the D-4 and D-5 position during T cell activation have been well documented. Recently it has been proposed that phosphoinositides phosphorylated on the D-3 position of the inositol ring by a novel phosphoinositide (PI) 3 kinase may also be important in cell activation. In the present study we have examined the levels and regulation of D-3 phosphoinositides in T cells activated by the TcR/CD3 complex and CD2 antigens. The data show the existence of phosphatidylinositol-(3)-monophosphate [PtdIns(3)P], phosphatidylinositol-(3,4)-bisphosphate [PtdIns(3,4)P2] and phosphatidylinositol-(3,4,5)-trisphosphate [PtdIns(3,4,5)P3] in T cells. Activation of the TcR/CD3 complex or CD2 antigen results in modulation of PtdIns(3,4)P2 and a putative PtdIns(3,4,5)P3 in T cells but does not change levels of PtdIns(3)P. These data provide the first evidence that lipid products of a PI3 kinase exist in T cells.
GLP‐1 receptor agonists vs. DPP‐4 inhibitors for type 2 diabetes: is one approach more successful or preferable than the other? (2014)

GLP-1RAs provide superior glycaemic control and weight loss vs. DPP-4 inhibitors in patients with T2D. DPP-4 inhibitors may sometimes be preferred to a GLP-1RA if weight is not a concern, oral administration is a desirable feature or when a GLP-1RA cannot be tolerated.
Guanosine tetraphosphate and its analogs. Chemical synthesis of guanosine 3',5'-dipyrophosphate, deoxyguanosine 3',5'-dipyrophosphate, guanosine 2',5'-bis(methylenediphosphonate), and guanosine 3',5'bis(methylenediphosphonate) (1976)

A new procedure for the synthesis of the pyrophosphate bond has been employed in the preparation of nucleoside dipyrophosphates from nucleoside 3',5'-diphosphates. The method makes use of a powerful phosphorylating agent generated in a mixture of cyanoethyl phosphate, dicyclohexylcarbodiimide, and mesitylenesulfonyl chloride in order to avoid possible intramolecular reactions between the two phosphate groups on the sugar ring. That such reactions can readily occur was shown by the facile cyclization of deoxyguanosine 3',5'-diphosphate to P1,P2-deoxyguanosine 3',5'-cyclic pyrophosphate in the presence of dicyclohexylcarbodiimide alone. The phosphorylation reagent was initially tested in the conversion of deoxyguanosine 3',5'-diphosphate to the corresponding 3',5'-dipyrophosphate and was then used to phosphorylate 2'-O-(alpha-methoxyethyl)guanosine 3',5'-diphosphate, which had been prepared from 2'-O-(alpha-methoxyethyl)guanosine. In the latter case, the addition of the two beta phosphate groups was accomplished in 40% yield. Removal of the methoxyethyl group from the phosphorylated product gave guanosine 3',5'-dipyrophosphate, which was shown to be identical with guanosine tetraphosphate prepared enzymatically from a mixture of GDP and ATP. A modification of published procedures was also necessary to effect the synthesis of guanosine bis(methylenediphosphonate). Guanosine was treated with methylenediphosphonic acid and dicyclohexylcarbodiimide in the absence of added base. The product consisted of a mixture of guanosine 2',5' - and 3',5'-bis(methylenediphosphonate), which was resolved by anion-exchange chromatography. The 2',5' and 3',5' isomers are interconvertible at low pH, with the ultimate formation of an equilibrium mixture having a composition ratio of 2:3. The predominant constituent of this mixture has been unequivocally identified as the 3',5' isomer by synthesis from 2'-O-tetrahydropyranylguanosine.
Scaling of the surface migration length in nanoscale patterned growth (2009)

Scaling of the surface migration length in nanoscale patterned growth (NPG) is investigated as a function of the lateral dimension LM of a mask film fabricated on a substrate for selective epitaxy. By reducing LM below the surface migration length, any nucleation on the mask is avoided through the evaporation and surface out-diffusion of adatoms. The upper limit of LM for NPG LM,c corresponds to the surface migration length on the mask. An equation, identical to that for two-dimensional step-flow growth, is derived for NPG. However, the boundary conditions at the substrate-mask interface are affected by the surface potential difference and are different from those at the terrace edges of a homogeneous stepped surface. This results in a scaling law for surface migration length, which is proportional to the diffusion constant D and the critical incident flux Fc in the form (D/Fc)1/α with α decreasing from 4 to 2 as evaporation becomes dominant. NPG of GaAs for LM,c∼200 nm(α∼3.8) is demonstrated at ∼600 °C with molecular beam epitaxy.
Theophylline and selective phosphodiesterase inhibitors as anti-inflammatory drugs in the treatment of bronchial asthma (1995)

Theophylline has been in clinical use for the treatment of bronchial asthma and other respiratory diseases for well over 50 yrs. Over this time, a considerable body of evidence has accumulated to show that this drug has a wide range of pharmacological actions, in addition to the well-recognized action on airway smooth muscle function. Current evidence suggests that part of the therapeutic value of theophylline in the treatment of asthma is by virtue of an anti-inflammatory or immunomodulatory effect, although the actual mechanism of action remains unclear. It has been proposed that the observed anti-inflammatory effects of theophylline could be attributed to phosphodiesterase (PDE) inhibition, and recently the type III and IV isoenzymes have been characterized in a number of inflammatory cells. This article reviews the evidence that theophylline and the newer more selective type IV PDE isoenzyme inhibitors can inhibit the activation of inflammatory cell types, such as T-lymphocytes, eosinophils, mast cells and macrophages, in vitro. The evidence supporting the ability of theophylline and selective PDE IV isoenzyme inhibitors to modify allergic inflammation both in animal models and clinical asthma is also discussed. We conclude that theophylline possesses important anti-inflammatory and immunomodulatory activity and that, in light of this evidence, it is timely to reconsider the place of theophylline in the treatment of asthma.
Cytogenetic findings in six posterior uveal melanomas: Involvement of chromosomes 3, 6, and 8 (1990)

Six posterior uveal melanomas were karyotyped after short-term culture. One had a normal chromosome complement; the remaining five had limited chromosome changes. Involvement of chromosomes 1 and 6 was noted in two and four cases, respectively, and three ciliary body tumours demonstrated both monosomy 3 and i(8q).

Formation of active derivatives of glucoamylase I during the digestion with fungal acid protease and .ALPHA.-mannosidase. (1978)

Glucoamylase I (MW 90, 000; N-terminal alanine) was selectively produced by a sub-merged culture of Aspergillus awamori var. kawachi as an enzyme having the ability to digest even raw starches, and was converted into a modified active glucoamylase decreasing in mole-cular weight during the digestion with the acid protease of the same mold strain. The modified glucoamylase (MW 83, 000; N-terminal alanine plus isoleucine) was resembled to an inter-mediate type of glucoamylase I', and exhibited hydrolysis curves for gelatinized potato starch and maltose in the same manner as that of glucoamylase I; but it did not digest raw starches and was not adsorbed onto cornstarch, and showed the lower hydrolysis limit of 80 percent for glycogen. The carbohydrate contents of glucoamylase I decreased 59 percent during the digestion with fungal α-mannosidase. The carbohydrate-split glucoamylase (MW 86, 000; N-terminal alanine) was unstable at pH 9 or at 65°C in the same extent as glucoamylase I', but was identical with glucoamylase I in the hydrolysis curves for various substrates, the digestibility for raw starches and the adsorbability onto cornstarch. Multiple forms of glucoamylase were observed when native glucoamylase I was degraded stepwisely with fungal acid protease and α-mannosidase.
Purification, characterization, and cloning of a heme-binding protein (23 kDa) in rat liver cytosol (1995)

A heme-binding protein (designated HBP23) has been purified from rat liver cytosol using heme-affinity chromatography and either reverse-phase high-performance liquid chromatography or sequential ion-exchange chromatography. The protein (23 kDa) binds heme with an affinity (Kd = 55 nM) higher than that of the abundant cytosolic heme-binding proteins, heme-binding protein (HBP)/liver fatty acid-binding protein (L-FABP) and the glutathione S-transferases (GSTs) (Kd = 100-200 nM). HBP23 is present in the cytosol of liver, kidney, spleen, small intestine, and heart, with the liver showing the highest content. A cDNA coding the 23-kDa protein was cloned using reverse transcription polymerase chain reaction with degenerative oligonucleotides derived from partial amino acid sequences. The cloned cDNA encoded 199 amino acids, and its amino acid sequence showed no homology to HBP/L-FABP, GSTs, or any other heme-binding proteins or hemeproteins. Homology search showed that HBP23 is highly homologous to mouse macrophage 23-kDa stress protein, which is inducible by oxidant stress in peritoneal macrophages [Ishii, T., Yamada, M., Sato, H., Matsue, M., Taketani, S., Nakayama, K., Sugita, Y., and Bannai, S. (1993) J. Biol. Chem. 268, 18633-18636]. Thioredoxin peroxidase as well as HBP23 and the mouse macrophage 23-kDa stress protein are members of the peroxiredoxin family, a recently recognized class of antioxidant proteins [Chae, H. Z., Chung, S. J., & Rhee, S. G. (1994) J. Biol. Chem. 269, 27670-27678]. An increase in HBP23 mRNA was observed in Hepa 1-6 cells after treatment with heme and cadmium and during liver regeneration after partial hepatectomy.(ABSTRACT TRUNCATED AT 250 WORDS)
Total Synthesis and Antitumor Activity of 12,13-Desoxyepothilone F:  An Unexpected Solvolysis Problem at C15, Mediated by Remote Substitution at C21 (2000)

A new epothilone analogue, 12,13-desoxyepothilone F (dEpoF, 21-hydroxy-12,13-desoxyepothilone B, 21-hydroxyepothilone D), was synthesized and evaluated for antitumor potential. A convergent strategy employed for the semipractical synthesis of 12,13-desoxyepothilone B (dEpoB) has been utilized to yield an amount of dEpoF sufficient for relevant biological studies. The results from an in vitro assay reveal that this new analogue is highly active against various tumor cell lines with a potency comparable to that of dEpoB. In particular, the growth of resistant tumor cells is inhibited by dEpoF at concentrations where paclitaxel (Taxol) is basically ineffective. A preliminary assessment of its in vivo activity is also promising. The new analogue, containing an additional hydroxyl group at C21, exhibits advantages over other epothilones in terms of water solubility, and can serve as a readily functionalizable handle to produce other useful compounds for pertinent biological studies.
Immunosuppressive drug therapy for rheumatic disease (1993)

The role of intravenous and oral cyclophosphamide in treating systemic lupus and Wegener's granulomatosis was examined in several large studies during the past year. Oral cyclophosphamide for 2 months followed by prednisone alone was relatively ineffective in preventing disease progression in lupus nephritis patients with initially abnormal serum creatinine values. A controlled trial in which three regimens for treating lupus nephritis were compared resulted in superiority of long-term intravenous cyclophosphamide therapy over pulse prednisone or short-term intravenous cyclophosphamide. Two open studies describe treatment of neuropsychiatric lupus with pulse cyclophosphamide. Patients with clinical evidence of inflammatory disease of the central nervous system appeared to respond to this therapy even if antiphospholipid antibodies were present. Analysis of a large cohort of patients with Wegener's granulomatosis showed a high incidence of cancer at long-term follow-up as well as a high incidence of recurrence, often several years after induction of remission with cyclophosphamide plus prednisone. Much progress was made in defining the mechanisms of action of cyclosporine. Additional studies examine the role of cyclosporine in necrotizing scleritis complicating rheumatoid arthritis. Concomitant administration of nonsteroidal anti-inflammatory drugs and cyclosporine to rheumatoid arthritis patients resulted in increased short-term deterioration of renal function. Studies of patients with various autoimmune diseases showed an association of the mean, maximal, and cumulative doses of cyclosporine with biopsy-proven nephropathy. Cytarabine was tried at low doses in the treatment of rheumatoid arthritis with improvement in some patients. Current Opinion in Rheumatology 1993, 5:282-292
Computer-aided socket design for trans-femoral amputees (1993)

Computer-aided socket design (CASD) is a technique for the design of prosthetic sockets using the advantageous features of computer graphics and calculation. This paper describes a computer-aided technique used to design sockets for patients with trans-tibial lower limb amputations.
