Salt and Water Movement in Unsaturated Frozen Soil (1972)

Abstract Salt and water movement was measured in unsaturated frozen soil columns incubated under a thermal gradient for 3, 6, or 9 weeks. Both water and salt moved from the warmer to cooler areas in the soil, creating a twofold concentration difference over a 24‐cm distance. Movement of CaCl 2 , LiI, and K 2 SO 4 was studied in detail. Cation exchange reactions and salt solubilities at high concentrations affected the movement. Although the results suggested that mass flow of dissolved salts in a liquid film of water was the principal transfer mechanism, both vapor and salt diffusion were sometimes significant. Thermal diffusion and salt sieving did not appear to be important. Since the vapor pressure of ice controls the water potential in frozen soil, the amount of unfrozen water and matric suction could be calculated from a water release curve and data from ice suspensions in salt solutions. These results led to the conclusion that mass flow in the liquid phase is described by Darcy's law. Thus, salt flow as well as net water transfer can probably be predicted in unsaturated frozen soil using information available from unfrozen systems.
Prospective study of myelin water fraction changes after mild traumatic brain injury in collegiate contact sports (2018)

In this preliminary study, MWF was found to be increased in the brains of CSPs compared with the brains of controls, suggesting acute/chronic MWF alterations in CSPs from previous injuries. Increases in the MWF were also demonstrated in the brains of CSPs 3 months after the players sustained an mTBI. The full clinical significance of an increased MWF and whether this reflects axon neuropathology or disorderly remyelination leading to hypermyelination has yet to be determined.
Treatment of Wide-Neck Basilar Tip Aneurysms Using the Web II Device (2013)

Endovascular treatment has assumed a major role in the management of intracranial aneurysms. Although current techniques have proven extremely effective in the embolization of a large number of intracranial aneurysms, wide-necked basilar tip aneurysms represent a subset that continues to pose technical challenges in treatment. This study reports our experience with WEB II, a new embolization device employed in four patients with this type of aneurysm.

Plasmonic Biosensors Based on Deformed Graphene (2022)

Rapid, accurate, and label-free detection of biomolecules and chemical substances remains a challenge in healthcare. Optical biosensors have been considered as biomedical diagnostic tools required in numerous areas including the detection of viruses, food monitoring, diagnosing pollutants in the environment, global personalized medicine, and molecular diagnostics. In particular, the broadly emerging and promising technique of surface plasmon resonance has established to provide real-time and label-free detection when used in biosensing applications in a highly sensitive, specific, and cost-effective manner with small footprint platform. In this study we propose a novel plasmonic biosensor based on biaxially crumpled graphene structures, wherein plasmon resonances in graphene are utilized to detect variations in the refractive index of the sample medium. Shifts in the resonance wavelength of the plasmon modes for a given change in the RI of the surrounding analyte are calculated by investigating the optical response of crumpled graphene structures on different substrates using theoretical computations based on the finite element method combined with the semiclassical Drude model. The results reveal a high sensitivity of 4990 nm/RIU, corresponding to a large figure-of-merit of 20 for biaxially crumpled graphene structures on polystyrene substrates. We demonstrate that biaxially crumpled graphene exhibits superior sensing performance compared with a uniaxial structure. According to the results, crumpled graphene structures on a titanium oxide substrate can improve the sensor sensitivity by avoiding the damping effects of polydimethylsiloxane substrates. The enhanced sensitivity and broadband mechanical tunability of the biaxially crumpled graphene render it a promising platform for biosensing applications.
Culture Factors Affecting the Success Rate of in Vitro Fertilization and Embryo Transfera (1985)

The development of one-cell mouse zygotes to the blastocyst stage in vitro has been used as a quality control for the media and handling procedures employed for human in vitro fertilization and embryo transfer (IVF/ET). One-cell mouse zygotes were placed in culture in medium containing bovine serum albumin. Aliquots of the same batch of medium containing female patients' homologous serum were used for the fertilization and culture of human oocytes. The following procedures were associated with high rates of mouse embryo development and human pregnancies following IVF/ET: adequate gassing and equilibration of the medium, double-rinsing of pipets and catheters used to handle embryos, use of a HEPES-buffered medium for manipulating embryos in the absence of an atmosphere containing 5% CO2, control of excessive temperature in the vicinity of the embryos, and ET using medium containing 50% patient's serum. The institution of these procedures gave more consistent pregnancy rates. However, there was no obvious association between fertilization and cleavage of human oocytes and the quality of the medium ascertained by the mouse embryo development test. In a continuing trial, we are comparing two culture media (modified Tyrode's and a medium formulated on the composition of human fallopian tube fluid [HTF]) and two culture techniques (culture in medium under oil in petri dishes and in loosely capped tubes). Significantly more mouse zygotes developed in HTF medium compared to Tyrode's medium. In a randomized 2 X 2 factorial trial with human IVF/ET, the highest pregnancy rate occurred when fertilization and culture were carried out in HTF medium under oil, but numbers are not yet sufficient to show any statistical difference between treatments.
A linear trinuclear CaZn2complex with bridging benzoate ligands (2002)

The title complex, [CaZn2(C7H5O2)6(C10H14N2O)2], has a centrosymmetric mol­ecule containing a linear array of two zinc and one central calcium ions bridged by two sets of three unsymmetrical benzoate ligands. Zinc is additionally coord­inated by a nitro­gen-base ligand to give distorted tetrahedral geometry, while the coordination of calcium by six benzoate O atoms is close to regular octahedral.
Synthesis of carbon‐14 labeled vigabatrin (1993)

Abstract Carbon‐14 labeled vigabatrin was synthesized in 5 steps from 5‐hydroxymethyl‐2‐pyrrolidone tosylate and NaCN‐[ 14 C]. A key step involved reduction of the resulting nitrile in the presence of excess dimethylamine to give the dimethylamino‐ethyl 2‐pyrrolidone derivative in one step. This afforded an overall radiochemical yield of 22% and radiochemical purity greater than 98%.
Immunodetection assays for the quantification of seasonal common cold coronaviruses OC43, NL63, or 229E infection confirm nirmatrelvir as broad coronavirus inhibitor (2022)

Besides pandemic SARS-CoV-2, also endemic seasonal human common cold coronaviruses (hCoVs) have a significant impact on human health and economy. Studies on hCoVs and the identification of antivirals are therefore crucial to improve human well-being. However, hCoVs have long been neglected and the methodology to study virus infection, replication and inhibition warrants being updated. We here evaluated the established plaque-based assays to determine viral titers and cell-to-cell spread and developed protocols for the immunodetection of the viral nucleocapsid protein by flow cytometry and in-cell ELISA to study infection rates at early time points. The developed protocols allow detection of hCoV-229E infection after 2, and hCoV-NL63 and -OC43 infection after 3 days at a single cell level or in a 96 well microtiter format, in large sample numbers without being laborious or expensive. Both assays can be applied to assess the susceptibility of cells to hCoV infection and replication, and to determine the efficacy of antiviral compounds as well as neutralizing antibodies in a sensitive and quantitative manner. Application revealed that clinically applied SARS-CoV-2 targeting monoclonal antibodies are inactive against hCoVs, but that the viral polymerase targeting antivirals remdesivir and molnupiravir are broadly active also against all three hCoVs. Further, the in-cell ELISA provided evidence that nirmatrelvir, previously shown to broadly inhibit coronavirus proteases, also prevents replication of authentic hCoVs. Importantly, the protocols described here can be easily adapted to other coronavirus strains and species as well as viruses of other families within a short time. This will facilitate future research on known and emerging (corona)viruses, support the identification of antivirals and increase the preparedness for future virus outbreaks.

Parameter Estimation In The Presence Of Low Rank Noise (2005)

We extend the classical problem of parameter estimation in the linear model to the case where low rank, or structured, noise is present in addition to the usual full rank noise. Many of the solutions are written in terms of oblique projections, a natural extension of the orthogonal projections of the classical case. The obliqueness of the pro jections stems directly from the non-orthogonality between the signal subspace and the structured noise subspace. We show how rank reduction techniques may be applied simul taneously to the signal and structured noise subspaces.
Immunoglobulins in serum and cerebrospinal fluid from patients with acute Guillain-Barré syndrome (1986)

IgG, IgA, IgM and IgE were quantified in serum and IgG and total protein were quantified in cerebrospinal fluid (CSF) from 80 patients with acute Guillain-Barré syndrome. The serum concentrations of IgM and IgA were significantly increased in approximately 25% of the patients, whereas the concentrations of IgG and IgE were normal. Increased CSF concentrations of IgG were found in more than 90% of the patients and correlated with increased CSF total protein concentrations. The CSF IgG/total protein ratio, CSF IgG index and Tourtellotte's formula were used to determine intra-thecal IgG synthesis in 30 of the patients. In eight of the patients the results of the CSF IgG index and Tourtellotte's formula were significantly increased, while in the remaining seven patients increased values were obtained using only one of these formulae. The CSF IgG/total protein ratio was normal in all the patients. Oligoclonal bands were not detected in any of the sera or CSF. Antibodies to peripheral nerve tissue were detected in approximately 30% of the patient sera, but could not be detected in the CSF.
Chronic fluoxetine prevents fear memory generalization and enhances subsequent extinction by remodeling hippocampal dendritic spines and slowing down systems consolidation (2019)

Fear memory overgeneralization contributes to the genesis and persistence of anxiety disorders and is a central hallmark in the pathophysiology of post-traumatic stress disorder (PTSD). Recent findings suggest that fear generalization is closely related to hippocampal dependency during retrieval. The selective serotonin reuptake inhibitor (SSRI) fluoxetine has been used as a first-line treatment for PTSD; however, how it exerts its therapeutic effect remains a matter of debate. Here, using contextual fear conditioning in rats, we show that chronic fluoxetine treatment prevents fear generalization and enhances subsequent extinction. Moreover, fluoxetine treatment after extinction prevents spontaneous recovery. The mechanism through which fluoxetine affects generalization and extinction seems to be through the postponement of systems consolidation, thereby maintaining hippocampal involvement during retrieval. Such an effect relies on a remodeling of dendritic spines in the hippocampus, as well as the number of mature, mushroom-type spines promoted by fluoxetine treatment. In order to further investigate whether fear generalization is a potential predictor of extinction effectiveness, we categorized a large naive population according to their generalization rate. We found that discriminator rats showed a better extinction profile compared to generalizers, suggesting that the generalization rate predicts extinction effectiveness. Hence, we propose that the therapeutic strategy of choice should take into account the extension of memory generalization, in which therapies based on extinction could induce a better outcome in patients who present less fear overgeneralization. These results open new avenues for the development of interventions that prevent fear generalization by maintaining memory dependency of the hippocampus.
SOFTWARE UNDERACTUACTION FOR REDUCED INPUT CONTROL OF LARGE DEGREE OF FREEDOM STRUCTURES: DEVELOPMENT OF A HAND CONTROL STRATEGY FOR ADVANCED UPPER EXTREMITY PROSTHETICS (2008)

Pattern recognition strategies have been explored for prosthetic hand control for over 20\nyears, but have not been commercially implemented. [1] Articulated research hands now rival\nhuman hand articulation, presenting new control challenges. Because no methods of pro-\ncessing signals of any source (cortical, peripheral nerve or myoelectric) are currently capable\nof delivering joint angle intent, the information content of user intent must be expanded.\nControl information for the 15 to 20 joints of a highly articulated hand must be derived from\na single variable of grasp information. Two strategies are proposed for augmenting intent to\ncontrol these hands. First, an array of grasp endpoints composed of the joint angles desired\nis created for each grasp, and the linear path to the desired endpoint constantly updated.\nFinger collisions are supervised by the user. Second, a larger set of grasp control parameters\nare explored. Using additional parameters allows more precise control of the arrangement of\nthe ngers than whole hand grasps, a greater degree of intuitive control over the arrangement\nof the ngers, and the possibility of dextrous manipulation.
Magnetic Properties of Amorphous Fe-Nd Alloys* (1990)

Melt-spun amorphous Fe 1- x Nd x alloys (0.11≤ x ≤0.60) were investigated by the magnetization measurement up to 143 kOe and the Mössbauer spectroscopy. The coercive field at 4.2 K increases abruptly at around x =0.30 with increasing x , amounting to 53 kOe at x =0.40. The hyperfine field of 57 Fe at 77 K is independent of x and about 300 kOe on an average, suggesting that the magnetic moment of Fe is about 2.0 µ B /atom throughout this system. On this assumption and the measured magnetization at 4.2 K, it is estimated that the average Nd moment is about 3.2 µ B /atom at the low x limit. This value corresponds to the free ion value of Nd 3+ . The Nd moment decreases with increasing x to one half, 1.6 µ B /atom. A ferromagnetic cluster model with large random anisotropy is proposed for the high coercivity alloys of this system. Magnetization curves at 4.2 K are well explained by the model, by an adjustment of the parameters for the anisotropy energy of the cluster and the inter-cluster coupling. The concentration dependence of the coercive field is discussed briefly.
Highly Efficient and Water‐Stable Lead Halide Perovskite Quantum Dots Using Superhydrophobic Aerogel Inorganic Matrix for White Light‐Emitting Diodes (2020)

Abstract At present, most of lead halide perovskite quantum dots (PQDs) embedded in an enclosed organic polymer or glass matrix can achieve high water stability, yet this limits their subsequent integration with light‐emitting diodes (LEDs) and other functional materials. Herein, a postadsorption process using superhydrophobic aerogel inorganic matrix (S‐AIM) with open structures is presented to enhance water stability of PQDs and compose new functions to them such as magnetism. The CsPbBr 3 PQDs integrated with the S‐AIM (AeroPQDs) exhibit a high relative photoluminescence quantum yield (PLQY, 75.6%) of 90.9% compared to pristine PQDs (PLQY, 83.2%). They preserve their initial PL intensity after 11 days of soaking in water and achieve a high relative PLQY stability (50.5%) after soaking for 3.5 months. The hydrophobic (rough) surface of the matrix, its pores with a well‐matched mean diameter that promotes the homogeneous integration of PQDs and hinders the penetration of water as well as the oleophylic functional groups covering the surface of these pores are the three factors responsible for the high water stability. Finally, AeroPQDs are easily integrated with other functional nanomaterials, such as Fe 3 O 4 nanoparticles for magnetic manipulation, due to their open structure.
Encapsulation of Luminescent Homoleptic [Ru(dpp)3]2+‐Type Chromophores within an Amphiphilic Dendritic Environment (2012)

A new series of homoleptic metallodendrimers has been synthesized through ruthenium-metal complexation by dendritically modified bathophenanthroline ligands. The presence of hydrophilic oligo(ethylene glycol) groups on the surface of the monodisperse metal complexes enabled the solubilization of all of the fractal species in a wide range of solvents, including water. The specific properties of all of these compounds have been systematically investigated by using photophysical techniques as a function of the generation number. Accordingly, the encapsulation of the highly luminescent [Ru(dpp)(3)](2+)-type (dpp=4,7-diphenyl-1,10-phenanthroline) core unit within a dendritic microenvironment creates a powerful means to shield the center from dioxygen quenching. This shielding effect, as exerted on the phosphorescent ruthenium-derived center, is reflected by enhanced emission intensities and extended excited-state lifetimes that are close to the highest values reported so far, even in an air-equilibrated aqueous medium. Interestingly, when inspecting the largest dendritic assembly, that is, the third-generation assembly, significant drops in emission quantum yields and lifetimes are observed. This anomalous behavior has been attributed to the folding of the branches towards the luminescent core.
