Novel active sweat pores based liveness detection techniques for fingerprint biometrics (2012)

Irrigation is a fundamental concept to the care of acute wounds and therefore of prime importance in all surgical specialties. A significant amount of research has been done in search of the most effective irrigation technique over the last three decades. There is evidence to show that irrigation is beneficial in the management of acute traumatic and elective wounds, but exactly which techniques and irrigation pressures needed for optimal outcome are still undetermined. A significant number of the studies to date lack the rigid scientific design needed in a climate of evidence-based medicine. There are substantial methodological flaws and a lack of standardisation between many studies hindering the ability to draw scientific conclusion and compare different studies. There are few randomised, controlled studies on human wounds, and extrapolation from animal studies must be done with caution. Investigation into different irrigation pressures for different levels of contamination is lacking. This would possibly produce a more logical approach for clinically managing acute wounds rather than a blanket treatment for all acute wounds irrespective of the level of contamination. Further research in this direction with greater attention to scientific methodology and design is needed.
Treatment with Paracetamol Can Interfere with the Intradialytic Optical Estimation in Spent Dialysate of Uric Acid but Not of Indoxyl Sulfate (2022)

Optical online methods are used to monitor the haemodialysis treatment efficiency of end stage kidney disease (ESKD) patients. The aim of this study was to analyse the effect of the administration of UV-absorbing drugs, such as paracetamol (Par), on the accuracy of optical monitoring the removal of uremic toxins uric acid (UA) and indoxyl sulfate (IS) during standard haemodialysis (HD) and haemodiafiltration (HDF) treatments. Nine patients received Par in daily dosages 1−4 g for 30 sessions. For 137 sessions, in 36 patients the total daily dosage of UV-absorbing drugs was less than 500 mg, and for 6 sessions 3 patients received additional UV-absorbing drugs. Par administration slightly affected the accuracy of optically assessed removal of UA expressed as bias between optically and laboratory-assessed reduction ratios (RR) during HD but not HDF employing UV absorbance of spent dialysate (p < 0.05) at 295 nm wavelength with the strongest correlation between the concentration of UA and absorbance. Corresponding removal of IS based on fluorescence at Ex280/Em400 nm during HD and HDF was not affected. Administration of UV-absorbing drugs may in some settings influence the accuracy of optical assessments in spent dialysate of the removal of uremic solutes during haemodialysis treatment of ESKD patients.
Transcatheter hepatic arterial and portal embolization in hepatocellular carcinoma. (1985)

原発性肝細胞癌に対する肝動脈塞栓術は有効な治療法であるが,腫瘍の完全壊死は困難で,しばしば再発を来すことは周知の如くである.そこで,今回著者らは動脈塞栓と同時に腫瘍存在部位の門脈の塞栓を行い,局所的な肝梗塞を作成しその臨床的,組織学的な抗腫瘍効果を検討した.その結果,塞栓により充分な肝梗塞が形成された部分では組織学的に被膜内腫瘍浸潤を含め,viableな腫瘍細胞は全くみられず壊死効果が極めて大きいことが判明した.塞栓術後の肝機能の悪化の程度は,動脈塞栓術と同程度であったが,回復がやや遅い傾向にあった.感染症の合併などもなく,症例によっては肝癌治療における系統的亜区域切除術にも匹敵する効果が期待される.

Islet Graft Assessment in the Edmonton Protocol (2004)

The success of the Edmonton Protocol for islet transplantation has provided new hope in the treatment of type 1 diabetes. This study reports on the assessment of 83 human islet grafts transplanted using the Edmonton Protocol since 1999. Cellular composition, as assessed by immunohistochemistry, showed a lower islet purity (approximately 40%) than has been reported in previous studies using dithizone staining to quantitate islet equivalents. Furthermore, grafts were found to contain substantial populations of exocrine and ductal tissue. Total cellular insulin transplanted was 8,097.6 +/- 3,164.4 microg/patient, and was significantly lower in bottom gradient layer grafts than top gradient layer or whole/combined grafts (P < 0.0005). A static incubation test for islet function gave a stimulation index of 3-4, although this measure did not correlate with posttransplant metabolic outcome. Furthermore, we confirmed a previously reported trend in which donor age affects islet yield and purity. It is important to note that a significant positive correlation was observed between the number of islet progenitor (ductal-epithelial) cells transplanted and long-term metabolic success as assessed an by intravenous glucose tolerance test at approximately 2 years posttransplant. In summary, careful assessment of islet graft composition is needed in a clinical transplantation program to accurately estimate islet purity and assess the contribution of other cell types present, such as islet progenitor cells.
Resolution degradation caused by multispur effect in chemically amplified extreme ultraviolet resists (2008)

Extreme ultraviolet (EUV) (92.5 eV) radiation is expected as a next-generation exposure source. When EUV photons enter resists, they are absorbed by resist molecules and photoelectrons are emitted. Photoelectrons with the initial energy of approximately 80 eV further induce ionization and generate ion pairs. Because the inelastic mean free path of these electrons is less than 1 nm, ion pairs are so narrowly distributed that they interact with each other through Coulomb forces. In this study, the details in the interaction among ion pairs were investigated by using a Monte Carlo simulation. It was found that the electric interaction between ion pairs significantly degrade the initial acid distribution. The dependence of resolution degradation and multispur effect on acid generator concentration was clarified. The acid generator loading of &amp;gt;10 wt % is effective for the suppression of resolution degradation.
Influence of the Micro- and Macro-Structural Parameters on the Dynamic Behavior of Structures Made of Polymers Reinforced with Short Glass Fibers (2018)

&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;In order to design vehicles with diminished gCO2/km emissions level, car manufacturers aim at reducing the weight of their vehicles. One of the solutions advocated by the automotive industry consists in the replacement of metallic parts by lighter systems made of polymer reinforced composites. Unfortunately, the numerical simulations set to evaluate the vibratory and acoustic performances of systems made of this kind of materials are often not sufficiently effective and robust so that convincing test/simulation correlations are rarely met. Indeed, for polymer-based materials, numerous parameters affect the vibroacoustic behavior. On the one hand, it is well known that the viscoelastic properties (Storage -Young- and dissipative moduli) of polymers depend on the temperature, loading frequency and sometimes the humidity content. On the other hand, when focusing of short-fiber composites, the injection molding process leads to an inhomogeneous spatial distribution (density and orientation) of the reinforcing fibers. For instance, through-thickness heterogeneity (orientation and volume fraction) is largely reported. More precisely, near the mid-surface, the volume fraction of fibers is increased and they are mostly oriented perpendicularly to the main direction of the flow. All in all, the composite material is anisotropic and its mechanical properties depend on the geometry in the part and the location within the part.&lt;/div&gt;&lt;div class="htmlview paragraph"&gt;In an industrial context, it is of great importance to rank the influence of the parameters and to set which ones are mandatory in a numerical simulation and which ones are of second order. Thus, the present paper aims at finding guidelines for modeling such complex materials, mainly focusing on the effect of through-thickness reinforcement heterogeneity. The results are based on experimental measurements and numerical simulations performed on an oil pan (typical of car industry) and rectangular plates made of short fiber reinforced polymer composite (SFRPC).&lt;/div&gt;&lt;/div&gt;
Simple Prediction Models for Breast Cancer Patients with Solitary Positive Sentinel Nodes--are they Valid? (2009)

Identification and prediction of breast cancer patients with metastases isolated to the sentinel lymph node(s) would potentially allow avoidance of axillary dissection and its complications. In this study, we evaluate the performance of two recently published models (Alkhatib et al. and Chagpar et al.) that attempt to predict patients who have isolated sentinel lymph node metastases. Both of these models reported a 5% rate of positive nonsentinel nodes in their respective lowest risk category. From 1997 to 2004, 465 breast cancer patients had a positive sentinel node and underwent axillary lymph node dissection at Mayo Clinic. To evaluate the Alkhatib model, patients were assigned to the following groups: group 1: 1 positive sentinel node and > or =1 negative sentinel node(s); group 2: >1 positive sentinel node and > or =1 negative sentinel node(s); group 3: 1 positive sentinel node and no negative sentinel node(s); group 4: >1 positive sentinel node and no negative sentinel node(s). To evaluate the Chagpar model, patients were assigned a score based on the sum of three factors: tumor size (T1a = 1, T1b or T1c = 2, T2 = 3, and T3 = 4 points), number of positive sentinel nodes (>1 positive sentinel node = 1 point), and ratio of positive/total sentinel nodes (>50% positive = 1 point). The chi-square test was used to compare our results to those of the original studies. For the Alkhatib model, we found that 30% (p < 0.0001) of Group 1 patients had nonsentinel node metastases. Using the Chagpar model, the percentage of patients with a cumulative score of 1 with a nonsentinel node metastasis was 17% (p = 0.19). In our cohort, neither model accurately predicted which patients have a < or = 5% chance of having nonsentinel metastases. These models are not adequate to identify patients in whom axillary dissection can be omitted.
The Effect of Residual Water on the Survival of Dried Bacteria During Storage (1958)

Summary: The optimum water activity (a w) for survival of dried bacteria has been determined by storing the organisms in water-vapour equilibrium with solutions of known a w value. The position of the optimum differed according to the composition of the suspending fluid, and the presence or absence of air in the storage atmosphere. For Staphylococcus aureus and Pseudomonas fluorescens, dried in papain digest and stored in vacuo, survival at 0·07, 0·11 and 0·16 a w was somewhat better than at 0·00 a w and 0·22 a w. Survival at 0·33–0·53 a w was much less. For Salmonella newport dried in the same medium the optimum, in vacuo was less clearly defined, but was well marked and close to 0·2 when stored in air. S. newport, when stored in vacuo, survived best at 0·22 a w after drying in a salts buffer or in dialysed horse serum, but in whole serum or the dialysable serum fraction survival was better at 0·00 a w. S. newport dried from water survived best at 0·00 a w, in vacuo, but at 0·43 a w in air. In the presence of sucrose the effect of a w, was relatively small. In the presence of glucose or arabinose survival at 0·00 a w, was better than at 0·22 a w, which in turn was much better than at 0·48 a w. In the presence of all three sugars the differences between results in vacauo and in air were small.
Abstract 767: TCR sequencing can identify and track tumor-specific T cell populations and is a predictive biomarker of response to DC vaccination in glioblastoma patients (2016)

Abstract While immunotherapeutic strategies are emerging adjunctive treatments for cancer, sensitive methods of monitoring the immune response after treatment remain to be established. We used a novel next generation sequencing (NGS) approach to determine whether quantitative assessments of tumor infiltrating lymphocyte (TIL) content and the degree of overlap of T cell receptor (TCR) sequences in brain tumors and peripheral blood were predictors of immune response and overall survival in glioblastoma (GBM) patients treated with autologous tumor lysate-pulsed dendritic cell (DC) immunotherapy. A significant correlation was found between a higher estimated TIL content and increased time to progression (TTP) and overall survival (OS). In addition, we were able to assess the proportion of shared TCR sequences between tumor and peripheral blood at time points before and after therapy, and found the level of TCR overlap to correlate with survival outcomes. Higher degrees of overlap, or the development of an increased overlap following immunotherapy, correlated with improved clinical outcome, and may provide insights into the successful, antigen-specific immune response.

Microstructural and tribological modifications in AISI H13 and DIN X100CrMoV 8-1-1 tool steel produced via plasma nitriding (2010)

The tool-steels AISI H13 and DIN X100CrMoV 8-1-1, which are used for different applications, were plasma nitrided in a low concentration nitrogen atmosphere at 500°C in order to increase the wear resistance. Then, metallurgical properties of these steels before and after nitriding were evaluated, and wear tests were also performed. The results demonstrated that plasma nitriding successfully increased the wear resistance on both steels. This study also demonstrated how the modified properties contributed in this way. Key words: plasma nitriding, wear, H13, DIN X100CrMoV 8-1-1.
BOUTONNIÈRE DEFORMITY: A SURGICAL CORRECTIVE PROCEDURE (1980)

A surgical procedure for the correction of chronic boutonnière deformity has been described. In essence, it is an anatomical reconstruction of the damaged extensor mechanism, and the procedure has proved to be a reliable method of improving both cosmetic deformity and function.
Submicron Contact Printing on Silicon Using Stamp Pads (1999)

Submicron scale microcontact printing of silanes onto silicon wafers is studied. Silicon microstructures are used as masters to prepare silicone rubber stamps, which are found to peel off the master easily even at wedge angles of 80° if the master has been silanized before. Stripe structures with periodicities down to 200 nm were generated. At these small scales, capillary condensation in the wedges of the stamp during the stamping process is difficult to avoid. We demonstrate a novel “stamp pad” technique which allows us to overcome this problem.
A regenerable immobilized NADH model. Reduction of α,α,α‐trifluoroacetophenone by 1, 4‐dihydronicotinamide anchored to macroreticular polystyrene (1983)

Abstract A regenerable dihydronicotinamide immobilized on a macroreticular polystyrene carrier was developed and used in an aqueous medium for the reduction of trifluoroacetophenone to the corresponding alcohol. It was shown that the second‐order rate constant for the polymer‐bound reagent is significantly lower than that of the low‐molecular‐weight analog 1‐benzyldihydronicotinamide. The observed reaction rate, however, was of the same order of magnitude as that due to enrichment of substrate in the polymeric pores. It was possible to depress the undesired side reactions to 10–15% per reaction cycle, thereby allowing reutilization of the functionalized polymer.
Second-order nonlinearities in the domain walls of periodically poled KTiOPO4 (2004)

The domain wall regions in periodically poled KTiOPO4 crystals were examined and found to give rise to phasematched second harmonic generation in the Čerenkov directions. This phenomenon is caused by the nonlinear coefficients d11 and d12, which are not present in single domain regions, but are nonzero at and close to domain walls. The appearance of these nonlinearities is attributed to strain, produced by the domain inversion process and results in the creation of a dc piezoelectric field.
Homoallyl ether rearrangement. A reaction proceeding via a cyclic eight-centred transition state (1974)

The thermolysis of homoallyl ethers proceeds in a concerted manner via an eight-centred transition state; thermolysis of 1-ethoxy-1-phenylbut-3-ene at 330–400° follows a first-order rate law, with Ea= 43 kcal/mol, ΔS‡=–10 cal K–1mol–1, affording ethylene, benzaldehyde, and propene as the only products, and the corresponding butyne derivative behaves similarly, giving allene as the only three-carbon fragment.
Heterogeneously catalyzed reactions with vegetable oils : epoxidation and nucleophilic epoxide ring-opening with alcohols (2003)

Chemical modification of vegetable oils, via epoxidation and epoxide ring-opening with alcohols was studied, using environmentally acceptable methods. Epoxidation of vegetable oils with peracids produced in the presence of heterogeneous acidic catalysts requires low contact between the epoxide and the acidic centers to avoid consecutive reactions. The main by-product is the ketone, obtained from the epoxide rearrangement reaction. Ketone formation is favored by strongly acidic catalysts and by high temperatures. Apolar solvents decrease the ketone formation, polar-protic solvents react with the epoxide and polar-aprotic solvents suppress this reaction. It is proposed that the epoxide rearrangement occurs via an intra-molecular hydride migration. Molecular sieves, as titanium support for the epoxidation of vegetable oils, do not bring any other advantage than the high surface area. Amorphous Ti-SiO2/TBHP (TBHP=tert-butyl hydroperoxide) has similar activity to Ti-MCM-41/TBHP. A high titanium dispersion renders the catalysts Ti-SiO2 more active and apolar-aprotic solvents improve the activity. Ti-SiO2 lacks of Ti-leaching, and it is reusable. Catalysts based on tungstenate anion/hydrotalcite-like materials showed a very high peroxide decomposition rate and very low epoxide yield. A new general reaction system for the epoxide ringûopening reactions with alcohols, under very mild reaction conditions and using heterogeneous catalysts, was developed. It allows the addition of less reactive alcohols such as those with the neo structure. Highly acidic catalysts are advantageous only when small and linear alcohols are added. For bulkier alcohols, highly acid catalysts decrease the selectivity because the quickly protonated epoxide rearranges faster than it reacts with the alcohols. Crystalline aluminosilicates, like Y zeolite, showed very low activity for the epoxide alcoholysis because most of the acidic sites are not accessible to the bulky epoxidized oil. Lamellar aluminosilicates of the montmorillonite type, especially those with a higher amount of Brönsted sites in the silicate layers, showed to be the best catalysts for the epoxide alcoholysis thanks to the enhanced Brönsted-acid site accessibility that the open structure offers. Regarding the effect of the alcohol structure, increasing the alcohol branching degree and/or its molecular size leads to lower reaction rates and lower selectivities.
Species- and Temperature-Dependency of the Decrease in Myofilament Ca2+ Sensitivity Induced by β -Adrenergic Stimulation (2001)

Although beta-adrenergic stimulation has been shown in many studies to decrease myofilament Ca2+ sensitivity in various types of cardiac muscle such as rat and rabbit ventricles, other studies disagree with this conclusion. In the present study, we aimed to explain these contradictory findings. We examined the effect of beta-adrenoceptor stimulation on Ca2+ sensitivity using guinea pig and rat ventricles. We performed the experiment at two different temperatures and compared the results. In guinea pig ventricles, isoproterenol and forskolin did not alter the relationship between [Ca2+]i and muscle force during the relaxation phase of tetanic contraction at either 24 degrees C or 30 degrees C. In rat ventricles, in contrast, isoproterenol shifted the [Ca2+]i-force curve to the right at 24 degrees C, but not at 30 degrees C. In guinea pig ventricles permeabilized by alpha-toxin, in which the cAMP/PK-A system is intact, the addition of cAMP did not decrease Ca2+ sensitivity. These results suggest that there are species- and temperature-dependent differences in the regulation of myofilament Ca2+ sensitivity by beta-adrenergic stimulation.
Enabling Service-Oriented Principles for the User Plane of Mobile Telecommunication Networks (2022)

This paper presents the architectural considerations of integrating a non-IP-based service routing solution, Name-Based Routing, to the 5G user plane. While entirely preserving the control plane procedures on the terminal, the carefully crafted considerations herein argue for a new Session Management Function functionality and the transitioning of the N4 interface to become a Service-Based Interface, i.e. Nupf. Furthermore, this paper presents User Plane Function provisioning procedures based on Software-Defined Networks principles mitigating the need for any manual management procedures and enabling cloud-native orchestration procedures for all 5G Core Network Functions.

In their Report, “An association between the kinship and fertility of human couples” (8 February, p. [813][1]), A. Helgason and colleagues provided solid evidence for an association between kinship and fertility in human couples. They demonstrated that greatest reproductive success was obtained
On reflection of radiation from moving objects (2008)

An analytical expression for the field reflected from a nonuniformity of the velocity of a moving medium is obtained. Specific features of the reflected radiation depending on the velocity and sizes of the non-uniformity domain and on the angle of incidence of radiation relative to the direction of motion are studied. The feasibility of experimental detection of the reflected radiation is demonstrated.
