Digital Delivery of Meditative Movement Training Improved Health of Cigarette-Smoke-Exposed Subjects (2018)

Many FA who flew prior to the ban on smoking in commercial aircraft exhibit an unusual pattern of long-term pulmonary dysfunction. This randomized controlled study tested the hypothesis that digitally delivered meditative movement (MM) training improves chronic obstructive pulmonary disease (COPD)-related symptoms in flight attendants (FA) who were exposed to second-hand cigarette smoke (SHCS) while flying. Phase I of this two-phase clinical trial was a single-arm non-randomized pilot study that developed and tested methods for MM intervention; we now report on Phase II, a randomized controlled trial comparing MM to a control group of similar FA receiving health education (HE) videos. Primary outcomes were the 6-min walk test and blood levels of high sensitivity C-reactive protein (hs-CRP). Pulmonary, cardiovascular, autonomic and affective measures were also taken. There were significant improvements in the 6-min walk test, the Multidimensional Assessment of Interoceptive Awareness (MAIA) score, and the COPD Assessment Test. Non-significant trends were observed for increased dehydroepiandrosterone sulfate (DHEAS) levels, decreased anxiety scores and reduced blood hs-CRP levels, and increased peak expiratory flow (PEF). In a Survey Monkey questionnaire, 81% of participants who completed pre and post-testing expressed mild to strong positive opinions of the study contents, delivery, or impact, while 16% expressed mild negative opinions. Over the course of the year including the study, participant adoption of the MM practices showed a significant and moderately large correlation with overall health improvement; Pearson's <i>R</i> = 0.62, <i>p</i> < 0.005. These results support the hypothesized benefits of video-based MM training for this population. No adverse effects were reported. <b>Clinical Trial Registration:</b> www.ClinicalTrials.gov, identifier: NCT02612389.
Neurobiological evaluation of thirty-one medicinal plant extracts using microtiter enzyme assays (2016)

Inhibition of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) related to Alzheimer’s disease as well as tyrosinase (TYR) relevant to Parkinson’s disease is an important approach to find novel drug candidates for these diseases. The extracts from fourteen plant species in various polarities were subjected to high-throughput screening against acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and tyrosinase (TYR), the key enzymes related to Alzheimer’s and Parkinson’s diseases. The extracts were subjected to the microtiter enzyme inhibition assays at 100 μg mL-1. Antioxidant effect of the extracts was tested for their scavenging activity against DPPH, DMPD, and NO radicals as well as their ferric- (FRAP) and phosphomolibdenum-reducing power (PRAP) and metal-chelation capacity. Total phenol and flavonoid quantities in the extracts were determined spectrophotometrically. HPLC analysis was performed on Atriplex lasiantha, Conringia grandiflora, and Vaccaria hispanica. The active extracts inhibiting AChE over 50 % were Centaurium erythraea subsp. rhodense (51.33 ± 3.35 %) and Posidonia oceanica (61.88 ± 2.23 %), while BChE was inhibited most effectively by the root extract of P. oceanica (82.55 ± 2.14 %), followed by Origanum haussknechtii (66.88 ± 0.17 %), which also had the highest inhibition toward TYR (35.28 ± 1.90 %). The extracts from Zostera noltii, P. oceanica, and Ricotia carnosula possessed the best DPPH scavenging activity, whereas Z. noltii caused the highest NO scavenging activity (70.19 ± 0.43 %) and FRAP (1.326 ± 0.065). Atriplex lasiantha and Ecballium elaterium had the strongest effect in PRAP and metal-chelation assays, respectively. Besides, A. lasiantha was found to be a rich source of rutin. Among the screened plants, Centaurium erythraea subsp. rhodense and Origanum haussknechtii, and the roots of Posidonia oceanica seems to deserve further investigation for their neuroprotective potential.
Catalytic Polymer Membranes for high Temperature Hydrogenation of viscous Liquids (2006)

Abstract Polymeric membranes with high oil fluxes were developed and catalytically activated by a new route of direct calcination of polymeric membranes charged by Pd or Pt catalyst precursors. High concentrations of citric acid mixed with the precursors afforded a decrease of the calcination temperature to 175°C. Membrane reactor tests in the flow through contactor mode displayed high reactivities for sunflower oil hydrogenation. Pt showed a similar activity to Pd catalysts as measured by iodine value and generated about 13% less trans‐isomers but 5% more stearic acid at an iodine value of 90. By means of alumina supported catalysts tests of methyl oleate (cis‐C18:1) and methyl elaidate (trans‐C18:1) hydrogenation exhibited a different pathway of reaction by either isomerization followed by reduction (Pd) or primarily direct reduction to methyl stearate (Pt).
Control: from mechanism to management (1990)

Control is often seen as an exclusively technical aspect of industrial process operation. However, this technology has an increasingly important impact on business performance. Industrial processes to which control is applied range from the traditional areas of the petrochemical industries to the power and water industries and the control of processes associated with maintaining environmental conditions in buildings. In each of these areas the relationship between the control systems and the process plant, and the contribution of the systems to operational management, has been transformed by the rapid development of computer-based technology.
Anterior Cruciate Ligament Injury Incidence Among Male and Female Professional Alpine Skiers (1999)

A retrospective review of anterior cruciate ligament injuries among professional alpine skiers was performed to compare sex-related differences in injury incidence. We screened 7155 ski patrollers or instructors (4537 men and 2618 women) for knee injuries before each ski season between 1991 and 1997. Screening involved a ski history questionnaire, a knee injury history questionnaire, and a knee physical examination. Any patient with an equivocal Lachman or pivot shift test was evaluated by KT-1000 arthrometry and excluded from the study if the manual maximum side-to-side difference was 3 mm or more. Thus, the study population was limited to subjects with intact anterior cruciate ligaments. Skiers injured during the study were identified through mandatory workers' compensation claims. Each injured skier was reevaluated using an injury questionnaire and physical examination. The men skied an average of 110 days per year (499,070 skier-days) and the women skied an average of 87 days per year (227,766 skier-days). Thirty-one skiing-related anterior cruciate ligament injuries were diagnosed, 21 in men and 10 in women. The incidence of ACL disruption was 4.2 injuries per 100,000 skier-days in men and 4.4 injuries per 100,000 skier-days in women. These data suggest that the incidences of anterior cruciate ligament injuries among male and female professional alpine skiers are similar.
Structuring of lifelog captured with multiple sensors by using neural network (2010)

The data related to our life experiences is called lifelog and it can easily be collected these days. Although lifelog research has been conducted for a long time, its application is still under development. In our research, we aimed at structuring of a lifelog with multiple sensors for the purpose of the application such as tools to recall memories. We actually captured a lifelog data with a device that has multiple sensors, and we estimated the events, i.e., the participants' activities. Then, the system correctly estimated events 70.4% of the time. Moreover, we efficiently showed the estimated results on the viewer we created. Finally, we verified the effectiveness of the research in experiment with two participants.
A 500-Mb/s quadruple data rate SDRAM interface using a skew cancellation technique (2001)

A quadruple data rate (QDR) synchronous DRAM (SDRAM) interface processing data at 500 Mb/s/pin with a 125-MHz external clock signal is presented. Since the QDR interface has a narrower data timing window, a precise skew control on data signals is required. A salient skew cancellation technique with a shared skew estimator is proposed. The skew cancellation circuit not only reduces the data signal skews on a printed circuit board down to 250 ps, but also aligns the data signals with an external clock signal. The entire interface, fabricated in a 0.35-/spl mu/m CMOS technology, includes a high-speed data pattern generator and consumes 570 mW of power at 3.0-V supply. The active die area of the chip with the on-chip data pattern generator is 2.4 mm/sup 2/.
Age-related changes in corneal thickness and endothelial characteristics (2013)

Purpose: To determine the influence of age on central corneal thickness (CCT), endothelial cell density (ECD), average cell size, coefficient of variation in cell size, and percentage of regular hexagonal cells; and to estimate the average ECD and CCT in seven age groups. Materials and methods: After obtaining informed consent, 211 Caucasian patients (358 eyes) were examined using a noncontact specular microscope at the Center of Eye Diseases in Vilnius University Hospital Santariskiu Clinic. The main corneal parameters were: ECD, average cell size, coefficient of variation in cell size, percentage of regular hexagonal cells, and CCT. Subjects (20–89 years) were stratified by age into seven groups. Correlations between CCT, endothelial parameters (ECD, percentage of regular hexagonal cells, average, coefficient of variation), and age were found. Student’s t -test and Pearson's correlation coefficient ( r ) values were calculated. Results: A total of 114 (54.03%) women and 97 (45.97%) men participated in the study. Average ECD (cell/mm 2 ) ranged from 2,931 (±371) in 20–29 year olds to 2,222 (±182) in 80–89 year olds; CCT (µm) ranged from 563 (±44) in 20–29 year olds to 540 (±35) in 80–89 year olds. A strong inverse correlation was observed between age and corneal ECD ( r =-0.650, P <0.01) and a weak inverse correlation was observed between age and CCT ( r =-0.156, P <0.01). ECD and CCT correlated directly ( r =0.232, P <0.01). The average size of corneal endothelial cells directly correlated with age ( r =0.586, P <0.01). There was no correlation between age and the coefficient of variation in cell size nor the percentage of regular hexagonal cells ( P >0.05). Conclusion: Young people have higher ECD. CCT also decreases, but its dependence on age is weaker. A lower cell density indicates a thinner cornea. The variation in cell size and percentage of regular hexagonal cells are not dependent on age. Keywords: cornea, endothelium, age-related changes
Increasing the Responsiveness of No. 2-D Diesel Fuels to Flow Improvers by Blending with Low Wax Diluents (1984)

&lt;div class="htmlview paragraph"&gt;Low temperature operation of diesel vehicles can be improved either by diluting the fuel with low-wax diluents or by treating the fuel with flow improvers. The objective of this study was to determine the effect of the combined use of flow improvers and diluents. Laboratory experiments were conducted using three low-wax diluents - a No. 1-D diesel fuel, a tar sands-derived fuel, and an unleaded gasoline - in various No. 2-D diesel fuels. All three diluents increased the responsiveness of the No. 2-D fuels to flow improver treatment, and the combined use of diluents and flow improvers synergistically reduced the filter plugging temperature. For example, these reductions ranged from 6 to 13°C for fuels containing 25% No. 1-D fuel and a flow improver, whereas the use of flow improver alone was ineffective in most of the fuels, and dilution alone caused reductions of only 3 to 5°C. Vehicle tests confirmed the synergistic effect of dilution and flow improver use.&lt;/div&gt;
Histopathological study of different organs of Charles foster rats under the exposure of Pueraria tuberosa (2021)

The present study was undertaken to investigate the safe doses of Pueraria tuberosa water extract (PTWE) on different organs. The OECD guidelines 407 of repeated toxicity was followed with respect to the selection of dose and days for different organs. The selected doses of PTWE were 250, 500, 1000 and 2000 mg/kg b wt for 7, 14, 21 and 28 days. Haematoxylin and eosin staining was used to study the morphological alterations in heart, intestine, testis, adrenal gland and spleen. In the present study, no adverse alterations in cardiac fibers of the heart, size and shapes in crypts and villi of intestine, seminiferous tubules and spermatozoa count in testis, three zones of adrenal gland, and spleen were seen in all treated groups of PTWE. There were no adverse morphological alterations found in described organs. The PTWE are safe at 1000 mg/kg b wt. up to 28 days and 2000 mg/ kg b. wt up to 21 days, respectively.
Formation Mechanism of Fe Nanocubes by Magnetron Sputtering Inert Gas Condensation (2016)

In this work, we study the formation mechanisms of iron nanoparticles (Fe NPs) grown by magnetron sputtering inert gas condensation and emphasize the decisive kinetics effects that give rise specifically to cubic morphologies. Our experimental results, as well as computer simulations carried out by two different methods, indicate that the cubic shape of Fe NPs is explained by basic differences in the kinetic growth modes of {100} and {110} surfaces rather than surface formation energetics. Both our experimental and theoretical investigations show that the final shape is defined by the combination of the condensation temperature and the rate of atomic deposition onto the growing nanocluster. We, thus, construct a comprehensive deposition rate-temperature diagram of Fe NP shapes and develop an analytical model that predicts the temporal evolution of these properties. Combining the shape diagram and the analytical model, morphological control of Fe NPs during formation is feasible; as such, our method proposes a roadmap for experimentalists to engineer NPs of desired shapes for targeted applications.
4,6-Dinitro-N,N′-di-n-octylbenzene-1,3-diamine, 4,6-dinitro-N,N′-di-n-undecylbenzene-1,3-diamine andN,N′-bis(2,4-dinitrophenyl)octane-1,8-diamine (2009)

4,6-Dinitro-N,N'-di-n-octylbenzene-1,3-diamine, C(22)H(38)N(4)O(4), (I), 4,6-dinitro-N,N'-di-n-undecylbenzene-1,3-diamine, C(28)H(50)N(4)O(4), (II), and N,N'-bis(2,4-dinitrophenyl)octane-1,8-diamine, C(20)H(24)N(6)O(8), (III), are the first synthetic meta-dinitroarenes functionalized with long-chain aliphatic amine groups to be structurally characterized. The intra- and intermolecular interactions in these model compounds provide information that can be used to help understand the physical properties of corresponding polymers with similar functionalities. Compounds (I) and (II) possess near-mirror symmetry, with the octyl and undecyl chains adopting fully extended anti conformations in the same direction with respect to the ring. Compound (III) rests on a center of inversion that occupies the mid-point of the central C-C bond of the octyl chain. The middle six C atoms of the chain form an anti arrangement, while the remaining two C atoms take hard turns almost perpendicular to the rest of the chain. All three molecules display intramolecular N-H...O hydrogen bonds between the amine and nitro groups, with the same NH group forming a bifurcated intermolecular hydrogen bond to the nitro O atom of an adjacent molecule. In each case, these interactions link the molecules into one-dimensional molecular chains. In (I) and (II), these chains pack so that the pendant alkyl groups are interleaved parallel to one another, maximizing nonbonded C-H contacts. In (III), the alkyl groups are more isolated within the molecular chains and the primary nonbonded contacts between the chains appear to involve the nitro groups not involved in the hydrogen bonding.
Bacterial Identification and Visualization of Bacterial Biofilms Adjacent to Fracture Sites After Internal Fixation (2022)

<b><i>Objectives:</i></b> The primary aims of this study were to determine if any correlation exists in cases of fracture fixation among: (1) bacterial profiles recovered from the instrumentation and adjacent tissues; (2) the type of orthopedic injury; and (3) the clinical outcome-union versus nonunion. A secondary goal was to compare culture and molecular diagnostics for identifying the bacterial species present following fracture fixation. <b><i>Design:</i></b> Single-institution, prospective case-control cohort study. <b><i>Setting:</i></b> Single level 1 trauma center. <b><i>Patients:</i></b> Forty-nine bony nonunion cases undergoing revision internal fixation and 45 healed fracture controls undergoing removal of hardware. <b><i>Intervention:</i></b> Bacterial infection was detected by standard microbial culture methods and by a pan-eubacterial domain, molecular diagnostic (MDx) assay. Confirmation of culture and MDx results was achieved with bacterial ribosomal 16S rRNA fluorescence <i>in situ</i> hybridization (FISH) to visualize bacterial biofilms. <b><i>Main Outcome Measurements:</i></b> MDx and microbial culture methods results were the primary study outcomes. <b><i>Results:</i></b> Ninety-four percent of the nonunion cohort and 93% of the union cohort had bacteria detected by the MDx. Seventy-eight percent of the nonunion cases and 69% of the controls were culture negative, but MDx positive. Although no significant differences in bacterial composition were observed between the cases and controls, differences were observed when cases were divided by comorbidities. <b><i>Conclusion:</i></b> The MDx is more sensitive than microbial culture in detecting bacterial presence. The lack of significantly different findings with regard to bacterial profile identified between the cases and controls suggests that host factors and environmental conditions are largely responsible for determining if bony union will occur. <b><i>Level of Evidence:</i></b> Diagnostic Level III. See Instructions for Authors for a complete description of levels of evidence.
Questioning Antiferromagnetic Ordering in the Expanded Metal, Li(NH3)4: A Lack of Evidence from μSR (2015)

We present the results of a muon spin relaxation study of the solid phases of the expanded metal, Li(NH3)4. No discernible change in muon depolarization dynamics is witnessed in the lowest temperature phase (≤25 K) of Li(NH3)4, thus suggesting that the prevailing view of antiferromagnetic ordering is incorrect. This is consistent with the most recent neutron diffraction data. Discernible differences in muon behavior are reported for the highest temperature phase of Li(NH3)4 (82-89 K), attributed to the onset of structural dynamics prior to melting.
Telepresence robot: Care delivery in different forms (2012)

Aging is associated with an increased risk for isolation. Information and communication technologies have been utilized to assist homecare of older adults. However, in addition to transmitting vital sign monitoring data for healthcare purposes, the older adults may expect more on communicating with their family members, as well as sharing of life experiences and feelings by different forms of interactions. Communication tools such as mobile phones, video conferencing systems did facilitate interpersonal communication in terms of real-time verbal communication. Mehrabian and Ferris reported that in face-to-face communication, clues from spoken words, voice tone, and facial expression contribute 7%, 38%, and 55% respectively to the total comprehension. [1]
Resistance Measurements for Multilayer Supported Membranes (2015)

It is possible to characterize, separately, the through-plane resistance of the neat ionomer skin layers as well as the ionomer filled support composite layer by measuring the through-plane resistance for a series of supported membranes varying only in ionomer skin thickness. The composite layer conductivity can then be compared to the conductivity of the neat ionomer, allowing for the determination of a "conductivity restriction" factor. This conductivity restriction factor can then be compared to the volume fraction of nonconductive support material in the composite layer to determine whether the impact on conductivity is due solely to acid site dilution or if there are additional losses. This analysis can be used to compare various support materials for their impact on through-plane resistance.
Ethanolamine Phosphate Linked to the First Mannose Residue of Glycosylphosphatidylinositol (GPI) Lipids Is a Major Feature of the GPI Structure That Is Recognized by Human GPI Transamidase (2006)

Glycosylphosphatidylinositol (GPI) anchoring of proteins is catalyzed by GPI transamidase (GPIT), a multisubunit, endoplasmic reticulum (ER)-localized enzyme. GPIT recognizes ER-translocated proteins that have a GPI-directing C-terminal signal sequence and replaces this sequence with a preassembled GPI anchor. Although the GPI signal sequence has been extensively characterized, little is known about the structural features of the GPI lipid substrate that enable its recognition by GPIT. In a previous study we showed that mature GPIs could be co-immunoprecipitated with GPIT complexes containing functional subunits (Vainauskas, S., and Menon, A. K. (2004) J. Biol. Chem. 279, 6540-6545). We now use this approach, as well as a method that reconstitutes the interaction between GPIs and GPIT, to define the basis of the interaction between GPI and human GPIT. We report that (i) human GPIT can interact with GPI biosynthetic intermediates, not just mature GPIs competent for transfer to protein, (ii) the ethanolamine phosphate group on the third mannose residue of the GPI glycan is not critical for GPI recognition by GPIT, (iii) the ethanolamine phosphate residue linked to the first mannose of the GPI structure is a major feature of GPIs that is recognized by human GPIT, and (iv) the simplest GPI recognized by human GPIT is EtN-P-2Manalpha1-4GlcN-(acyl)-phosphatidyl-inositol. These studies define the molecular characteristics of GPI that are recognized by GPIT and open the way to identifying GPIT subunits that are involved in this process.
