Mechanistic Analysis of Azine <i>N</i>-Oxide Direct Arylation: Evidence for a Critical Role of Acetate in the Pd(OAc)<sub>2</sub> Precatalyst (2010)

Detailed mechanistic studies on the palladium-catalyzed direct arylation of pyridine N-oxides are presented. The order of each reaction component is determined to provide a general mechanistic picture. The C-H bond cleaving step is examined in further detail through computational studies, and the calculated results are in support of an inner-sphere concerted metalation-deprotonation (CMD) pathway. Competition experiments were conducted with N-oxides of varying electronic characters, and results revealed an enhancement of rate when using a more electron-deficient species, which is in support of a CMD transition state. The effect of base on reaction rate was also examined and it was found that a carboxylate base was required for the reaction to proceed. This led to the conclusion that Pd(OAc)(2) plays a pivotal role in the reaction mechanism as more than merely a precatalyst, but also as a source of acetate base required for the C-H bond cleavage step.
Negative effects of parecoxib and indomethacin on tendon healing: an experimental study in rats (2009)

Conventional non-steroidal anti-inflammatory drugs (NSAIDs) and newer specific cyclooxygenase-2 (cox-2) inhibitors are commonly used in muscular skeletal trauma and in relation to orthopedic surgery to reduce the inflammatory response and pain. Studies have indicated that these drugs can have a negative effect on tendon healing in the early proliferative phase, but might be beneficial in the remodeling phase when inflammation might impede healing. Our study was designed to investigate if short-term administration of cox inhibitors after injury or postoperatively might have negative effects on the tendon healing. The right Achilles tendon of 60 rats was cut transversely, a 3 mm long segment of the tendon was removed and left unrepaired. The animals were then given parecoxib, indomethacin or saline intraperitoneally twice daily for 7 days. After 14 days, the animals were euthanized. The transverse and sagittal diameters in the healing area were measured and mechanical testing of the tensile strength of the tendons was performed. We found a significantly lower tensile strength in rats given both parecoxib and indomethacin compared to the control group. Stiffness in the healing tendons was significantly lower in the parecoxib group compared to both the placebo and the indomethacin groups. The transverse and sagittal diameters of the tendons were reduced in both the parecoxib and indomethacin groups. Both parecoxib and indomethacin impaired tendon healing; the negative effect was most pronounced with parecoxib.

Structural Characterization of Lignin and Its Degradation Products with Spectroscopic Methods (2017)

Lignin is highly branched phenolic polymer and accounts 15–30% by weight of lignocellulosic biomass (LCBM). The acceptable molecular structure of lignin is composed with three main constituents linked by different linkages. However, the structure of lignin varies significantly according to the type of LCBM, and the composition of lignin strongly depends on the degradation process. Thus, the elucidation of structural features of lignin is important for the utilization of lignin in high efficient ways. Up to date, degradation of lignin with destructive methods is the main path for the analysis of molecular structure of lignin. Spectroscopic techniques can provide qualitative and quantitative information on functional groups and linkages of constituents in lignin as well as the degradation products. In this review, recent progresses on lignin degradation were presented and compared. Various spectroscopic methods, such as ultraviolet spectroscopy, Fourier-transformed infrared spectroscopy, Raman spectroscopy, and nuclear magnetic resonance (NMR) spectroscopy, for the characterization of structural and compositional features of lignin were summarized. Various NMR techniques, such as 1 H, 13 C, 19 F, and 31 P, as well as 2D NMR, were highlighted for the comprehensive investigation of lignin structure. Quantitative 13 C NMR and various 2D NMR techniques provide both qualitative and quantitative results on the detailed lignin structure and composition produced from various processes which proved to be ideal methods in practice.
TRICERT: A Distributed Certified E-Mail Scheme. (2001)

In this paper we present protocols for distributed certified e-mail, which use encryption to ensure both confidentiality and fairness. As with other protocols for certified e-mail, ours achieve fairness by placing trust on an external entity, referred to as the Trusted Third Party (TTP). The TTP can become a bottleneck, however, and we explore scenarios that support a distributed TTP, in the context of both off-line and online protocols. With several servers dividing the TTP responsibilities, the level of confidence placed in individual servers can be reduced without compromising the TTP&apos;s overall trust. Keywords: Secure E-commerce, Fair Exchange, Certified E-mail, Semi-trusted TTP. 1
PERIOVULATORY LEVELS OF PLASMA PROGESTERONE AND LUTEINIZING HORMONE IN WOMEN (1969)

ABSTRACT Plasma LH and progesterone levels were measured around the time of ovulation in 16 normal menstrual cycles. No increased levels of progesterone were found before the LH peak. The maximal LH peak levels lasted for 16–20 h at which time the plasma progesterone rose to a concentration of 1 to 2 ng/ml. Following the fall in the LH concentration, there was a rapid rise in the plasma progesterone concentration, indicating the formation of a corpus luteum. The lowest basal body temperature coincided with the first significant rise in LH levels.
Influence of loop residues on the relative stabilities of DNA hairpin structures. (1988)

We have determined the relative stabilities and melting behaviors of DNA hairpin structures as a function of the nonbonded residues in the loop. The specific family of hairpin structures we investigated in this work is formed by the 16-mer sequence d[CGAACG(X)4CGTTCG], where X is deoxyadenosine, deoxycytidine, deoxyguanosine, or deoxythymidine. As shown below, this 16-mer can fold back on itself to form a family of DNA hairpin structures that possess a common hexameric stem duplex and a nonbonded loop of 4 nucleotides. For the hairpin structures investigated in this work, we varied the loop composition from all purine residues to all pyrimidine residues. (Formula: see text). We thermodynamically characterized the relative stabilities and melting profiles of these hairpin structures by a combination of spectroscopic and calorimetric techniques. To establish a thermodynamic "baseline," we also conducted parallel studies on the isolated hexameric duplex d[CGAACG).(CG-TTCG)], which corresponds to the common stem duplex present in each hairpin structure. Our spectroscopic and calorimetric data reveal the following: (i) The hairpin structure with four dT residues in the loop exhibits the highest melting temperature, while the corresponding hairpin structure with four dA residues in the loop exhibits the lowest melting temperature. (ii) The free energy data at 25 degrees C reveal the following order of DNA hairpin stability for the four structures studied here: T loop greater than C loop greater than G loop greater than A loop. In other words, the pyrimidine-looped hairpins of four residues are more stable than the purine-looped hairpins. (iii) The loop-dependent order of hairpin stability is paralleled by a similar trend in the calorimetrically determined transition enthalpies for hairpin disruption. Thus, the enhanced stability of the pyrimidine-looped hairpin structures relative to purine-looped hairpin structures is enthalpic in origin. To develop insight into the molecular basis for the thermodynamic differences, proton NMR spectroscopy was used to probe for structural disparities between the most stable hairpin structure (T loop) and the least stable hairpin structure (A loop). Two-dimensional nuclear Overhauser enhancement spectroscopy revealed connectivities between the residues in the stem duplexes of both hairpin structures that are consistent with B-form DNA. In addition, the nonbonded residues in both the T and A loops exhibited the same connectivity patterns. However, on the 5' side of the stem-loop junction, the T-loop residue exhibited a connectivity with the adjacent base pair of the stem duplex that is not observed for the corresponding A-loop residue. This difference in connectivities at the stem-loop junction may provide a structural basis for our observation that the T-looped hairpin structure is more stable than the corresponding A-looped hairpin structure.
Bubble formation at vibrated orifices: Medium‐chamber‐volume region (1984)

Abstract The bubble formation process at small, single, circular orifices at low gas flow rates is modified when the system is vertically vibrated in a sinusoidal fashion. For systems with significant gas chamber volume, bubble volume in the vibrated case is smaller than in the nonvibrated case. The vibrations increase the amount of liquid weeping through the orifice into the gas chamber. A simple inviscid model adequately predicts bubble formation in the medium‐chamber‐volume region at low values of amplitude and frequency of vibration and low viscosities. The boundaries of the transition from the FR ≫ 1 to the FR = 1 regions are described in terms of “the acceleration number/Eötvös number”.
Functional optical signal analysis: a software tool for near-infrared spectroscopy data processing incorporating statistical parametric mapping (2007)

Optical topography (OT) relies on the near infrared spectroscopy (NIRS) technique to provide noninvasively a spatial map of functional brain activity. OT has advantages over conventional fMRI in terms of its simple approach to measuring the hemodynamic response, its ability to distinguish between changes in oxy- and deoxy-hemoglobin and the range of human participants that can be readily investigated. We offer a new software tool, functional optical signal analysis (fOSA), for analyzing the spatially resolved optical signals that provides statistical inference capabilities about the distribution of brain activity in space and time and by experimental condition. It does this by mapping the signal into a standard functional neuroimaging analysis software, statistical parametric mapping (SPM), and forms, in effect, a new SPM toolbox specifically designed for NIRS in an OT configuration. The validity of the program has been tested using synthetic data, and its applicability is demonstrated with experimental data.
Micro-Raman study of diamondlike atomic-scale composite films modified by continuous wave laser annealing (1997)

We have modified the properties of diamondlike atomic-scale composite (DLASC) material of various thicknesses (5–70 μm) by means of cw Ar-ion laser annealing using a focused beam (∼2 μm spot size). These DLASC films [amorphous “diamondlike/quartzlike” a-(C:H/Si:O)] constitute a novel class of diamond-related materials. The laser annealing effects were investigated by micro-Raman scattering. The structure of these films can be altered locally from amorphous to nanocrystalline depending not only on the parameters of the annealing process (annealing time, laser intensity) but also the mechanical properties (hardness, stress) of the films. For comparison purposes we also measured the effects of thermal annealing.
Alterations in intensity of heart sounds after myocardial infarction. (1968)

A reduction in the intensity of the heart sounds is a familiar sequel to myocardial infarction. Sounds are sometimes described as muffled, weakened, or distant, and when the first sound alone is affected so that both sounds become of equal loudness a characteristic rhythm, sometimes known as "tick- tack rhythm", is produced. This change in inten- sity of the heart sounds has been attributed to alterations in heart rate, lengthening of the P-R interval, or to a lowering of systemic blood pres- sure, but it may be the only physical sign detectable, and not infrequently it is observed for the first time several days after the acute episode when the patient is making an otherwise uneventful recovery.

What Drives Decline Productivity in Ageing Tea Plantation - Soil Physical Properties or Soil Nutrient Status? (2014)

Over the years, the tea plantations in the Ribeira Valley, Brazil had been recording declining productivity and reduced tea quality. This had been associated with several factors including the age of the plantation, decling fertility, soil degradation among others factor. In this study, our objective was to identify the main driver of declining productivity in tea yield in the Ribeira Valley tea plantation in Brazil and to evaluate the effects of long-term tea cultivation on the physico-chemical changes and nutrient dynamics in the soil at 2 profile depths. Therefore, we evaluated the effects of long-term cultivation on changes in the physical and chemical properties of Acrisol Haplic planted to Tea in the Ribeira Valley region, Brazil. The soil samples were collected at two depths 0-10 cm and 10-20 cm in two representative plantations and analyzed for chemical, physical and mechanical soil properties. The selected sites; Thea Hills – TH1987 and Braço Preto – BP1972 presents different plantation ages on a similar cultivation practices. The harvested quantities of tea from the sites were monitored and their quality classified following international standards. We observed declining productivity in terms of harvested tea from both sites and the quality of harvested tea were better in TH1987 than BP1972. The soil nutrient study indicated an improvement in fertility parameters in the older plantation (BP1972). We observed degradation in the soil physical quality parament and all possible factors indicated that degradation of the soil structure through compaction was the main factor resulting in the observed declined productivity (quantitatively and qualitatively). Soil structure degradation adversely affects the soil functions including aeration, crop water use efficiency and soil nutrient conversion. We recommend appropriate soil tillage management in tea plantations too improve the productive cycle and capacities.
Force sensing microinstrument for measuring tissue properties and pulse in microsurgery (2003)

Miniaturized and "smart" instruments capable of characterizing the mechanical properties of tiny biological tissues are needed for research in biology, physiology, and biomechanics, and can find very important clinical applications for diagnostics and minimally invasive surgery (MIS). We are developing a set of robotic microinstruments designed to augment the performance of surgeons and clinicians during MIS. These microtools are intended to restore (or even enhance) the finger palpation capabilities that the surgeon exploits to characterize tissue hardness and to measure pulsating vessels in traditional surgery, but which are substantially reduced in MIS. This paper describes the main applications and the performance of a prototype miniature robotic instrument consisting of a microfabricated microgripper, instrumented with semiconductor strain-gauges as force sensors. The experimental set-up used for the in vitro tests reported in this paper consists of the microprobe mounted on a workstation and teleoperated. A haptic interface provides force feedback to the operator. We have demonstrated that the system can discriminate, both qualitatively and quantitatively, tiny skin samples based on their different elastic properties, and "feel" microvessels on the basis of pulsating fluid flowing through them.
Leveraging corporate skill knowledge - from ProPer to OntoProPer (2000)

Skill management systems serve as technical platforms for mostly, though not exclusively, corporate-internal market places for skills and know-how. The systems are typically built on top of a database that contains profiles of employees and applicants. Thus, the skills may be retrieved through database queries. However, these approaches incur two major problems, viz. the finding of approximate matches and the maintenance of skill data. In this paper we describe two systems that leverage corporate skill knowledge by offering advanced means for both. We present ProPer that uses means from decision theory to allow for compensate skill matching. Then, we describe OntoProPer that combines these methods with intelligent means for inferencing of skill data. For the latter an ontology provides background knowledge, i.e. conceptual structures and rules, which supplement the skill database with ground and inferred facts from secondary information, such as project documents. These supplement facts reduce maintenance efforts since much secondary information is gathered in the organizational memory through common working tasks.
OPIOID MECHANISMS CONTROLLING RENAL FUNCTION (1995)

1. Over the past 50 years considerable evidence has been reported suggesting that endogenous opioids participate in the control of renal function. 2. Exogenous administration of opioids produces profound changes in the renal excretion of water and sodium. 3. Opioids produce changes in urine output and urine sodium excretion by multiple integrated neural and hormonal mechanisms within the periphery, central nervous system and kidneys. 4. Although opioid antagonist administration does not consistently reveal an action of endogenous opioid systems on renal function, this may result from the quiescent nature of the endogenous opioid system under basal conditions. 5. Manipulations that activate endogenous opioid systems have begun to reveal important, previously unrecognized mechanisms that control kidney function and can enhance renal tubular sodium reabsorption in normal and potentially pathological states.
Structural Features Required for Inhibition of Soybean Lipoxygenase-2 by Propyl Gallate (1983)

The ability of 19 structural analogs of propyl gallate to inhibit purified soybean seed (Glycine max [L.] Merr. var. Ransom) lipoxygenase-2 (EC 1.13.11.12) was determined. The results indicate that the o-dihydroxy and not the ester function of propyl gallate is essential for inhibition of lipoxygenase. Catechol thus represents the minimum inhibitory structure. Among those compounds possessing an o-dihydroxy function, the K(i)' for inhibition of lipoxygenase is directly related to the lipophilicity of the inhibitor as measured by the octanol-water partition coefficient. The structural features of propyl gallate necessary for inhibition of lipoxygenase were found to differ from those required for inhibition of the plant mitochondrial alternative pathway. This further supports the concept that the alternative oxidase and lipoxygenase are functionally distinct species.
