Mutations in PIEZO2 Cause Gordon Syndrome, Marden-Walker Syndrome, and Distal Arthrogryposis Type 5 (2020)

Gordon syndrome (GS), or distal arthrogryposis type 3, is a rare, autosomal-dominant disorder characterized by cleft palate and congenital contractures of the hands and feet. Exome sequencing of five GS-affected families identified mutations in piezo-type mechanosensitive ion channel component 2 (PIEZO2) in each family. Sanger sequencing revealed PIEZO2 mutations in five of seven additional families studied (for a total of 10/12 [83%] individuals), and nine families had an identical c.8057G>A (p.Arg2686His) mutation. The phenotype of GS overlaps with distal arthrogryposis type 5 (DA5) and Marden-Walker syndrome (MWS). Using molecular inversion probes for targeted sequencing to screen PIEZO2, we found mutations in 24/29 (82%) DA5-affected families and one of two MWS-affected families. The presence of cleft palate was significantly associated with c.8057G>A (Fisher’s exact test, adjusted p value < 0.0001). Collectively, although GS, DA5, and MWS have traditionally been considered separate disorders, our findings indicate that they are etiologically related and perhaps represent variable expressivity of the same condition.

Alternative Polyadenylation Directs Tissue-Specific miRNA Targeting in Caenorhabditis elegans Somatic Tissues (2017)

mRNA expression dynamics promote and maintain the identity of somatic tissues in living organisms; however, their impact in post-transcriptional gene regulation in these processes is not fully understood. Here, we applied the PAT-Seq approach to systematically isolate, sequence, and map tissue-specific mRNA from five highly studied <i>Caenorhabditis elegans</i> somatic tissues: GABAergic and NMDA neurons, arcade and intestinal valve cells, seam cells, and hypodermal tissues, and studied their mRNA expression dynamics. The integration of these datasets with previously profiled transcriptomes of intestine, pharynx, and body muscle tissues, precisely assigns tissue-specific expression dynamics for 60% of all annotated <i>C. elegans</i> protein-coding genes, providing an important resource for the scientific community. The mapping of 15,956 unique high-quality tissue-specific polyA sites in all eight somatic tissues reveals extensive tissue-specific 3'untranslated region (3'UTR) isoform switching through alternative polyadenylation (APA) . Almost all ubiquitously transcribed genes use APA and harbor miRNA targets in their 3'UTRs, which are commonly lost in a tissue-specific manner, suggesting widespread usage of post-transcriptional gene regulation modulated through APA to fine tune tissue-specific protein expression. Within this pool, the human disease gene <i>C. elegans</i> orthologs <i>rack-1</i> and <i>tct-1</i> use APA to switch to shorter 3'UTR isoforms in order to evade miRNA regulation in the body muscle tissue, resulting in increased protein expression needed for proper body muscle function. Our results highlight a major positive regulatory role for APA, allowing genes to counteract miRNA regulation on a tissue-specific basis.
ACHIEVING k-ANONYMITY PRIVACY PROTECTION USING GENERALIZATION AND SUPPRESSION (2002)

Often a data holder, such as a hospital or bank, needs to share person-specific records in such a way that the identities of the individuals who are the subjects of the data cannot be determined. One way to achieve this is to have the released records adhere to k-anonymity, which means each released record has at least (k-1) other records in the release whose values are indistinct over those fields that appear in external data. So, k-anonymity provides privacy protection by guaranteeing that each released record will relate to at least k individuals even if the records are directly linked to external information. This paper provides a formal presentation of combining generalization and suppression to achieve k-anonymity. Generalization involves replacing (or recoding) a value with a less specific but semantically consistent value. Suppression involves not releasing a value at all. The Preferred Minimal Generalization Algorithm (MinGen), which is a theoretical algorithm presented herein, combines these techniques to provide k-anonymity protection with minimal distortion. The real-world algorithms Datafly and μ-Argus are compared to MinGen. Both Datafly and μ-Argus use heuristics to make approximations, and so, they do not always yield optimal results. It is shown that Datafly can over distort data and μ-Argus can additionally fail to provide adequate protection.
Use and Misuse of Triptans in France: Data from the Grim2000 Population Survey (2004)

The extent and nature of triptan use for headache relief has been evaluated in a large epidemiological survey in the French general population. Over 25 000 individuals were screened for headache and for triptan use. Of this sample, 290 triptan users were identified from whom extensive data on headache characteristics and healthcare resource consumption were obtained. The use of triptans is relatively infrequent, 0.2% in the general population, with only 7.5% of migraine sufferers using these drugs. The majority of triptan users were female (80%) and presented headache characteristics typical of migraine (80%). The remaining 20% of subjects were thus using triptans for headache types in which the utility of these drugs has not been demonstrated. Among migraineurs, triptan consumers reported more frequent and severe headaches than non-consumers, and reported a higher incidence of nausea and vomiting. The principal determinant of triptan prescription was consultation with a general practitioner (GP), which may itself have been triggered by the severity of the headaches. GPs, rather than specialists, are the primary prescribers of triptans in France.

Effect of conditioning and 3-year aging on the bond strength and interfacial morphology of glass-ionomer cement bonded to dentin (2022)

Aging did not reduce the bond strength of the conventional glass-ionomer cement to dentin with or without the use of a polyalkenoic acid conditioner. Remineralized dentin layer were observed in both conditioned and unconditioned 3-years specimens.
Estimation of oscillation parameters for power grids (2012)

A power system grid can be modeled as a circuit of various RLC-meshes. In case of a switching event, some of those RLC-meshes are excited. These will produce additional frequency components within the power signal. In this paper, a concept which uses a priori information of these meshes for event-characterization is presented. Frequency estimations done inside specific nodes of the power system are mapped to entries of a lookup-table. Depending on this map, events can be identified/localized. This concept is based on the database-assisted parameter estimation algorithm (DaPT). In consequence, the advantages of that system (low-amplitude detection, extensibility) will be preserved.

Reliability tests for a three dimensional chip stacking structure with through silicon via connections and low cost (2008)

In order to achieve the shorter circuit design of multiple chips, three-dimensional (3D) packaging technologies with through silicon vias were developed to achieve high performance, low power consumption and small packaging size. In this paper, a PCB (Printed Circuit Board) processing compatible structure of three-dimensional chip stacking with low cost and easy fabrication will be shown. 3D and through Si via connections were formed by UV laser drilling technology. Laser drilling is a non-contact manufacture method and laser beam with high energy can be focused to a small spot (15 mum beam diameter) for material ablating and removing without mask used. Several processes are the keys to accomplish 3D stacking, such as wafer thinning process, through silicon via forming process, dielectric layer forming process, metallization process, and inter chips bonding process. By integration of the mentioned key processes, a 3D chip stacking structure with 10 layers was carried out. The thickness of chip was 100 mum. Daisy chain pattern was designed for the electrical measurement of 3D stacking structure. The testing results show that the resistance of multi- chip stacking structure is about 0.056 Omega/cm. Some reliability test, such as temperature cycling test and pressure cooker test were also done. These testing results verified this PCB processing compatible 3D chip stacking technology with low cost is a reliable structure for 3D SiP (System in Packaging) module application.

The preclinical evaluation includes not only antitumor activity tests but also the investi- gation of the particular chemistry, the molecular targets within biological materials and the effect on the survival of a cell within its particular environment.
Electrophoretic characterization of proteins in the plasma membrane of porcine spermatozoa (1976)

Department of Animal Sciences, Purdue University, West Lafayette, Indiana 47907, U.S.A. Using immunological and cytochemical methods, several investigators have demonstrated that components on the surface of spermatozoa are altered during exposure of the spermatozoa to the female reproductive tract (Johnson &amp; Hunter, 1972; Aonuma et al., 1973; Oliphant &amp; Brackett, 1973). Recent evidence indicates that capacitation may also involve subtle modifications in the chemical composition of sperm membranes (Snider &amp; Clegg, 1975). The plasma membrane of porcine spermatozoa is being characterized in our laboratory to provide a foundation for subsequent studies of chemical changes during capacitation. In this paper, electrophoretic separation and partial characterization of proteins from plasma membrane of porcine spermatozoa is reported. Plasma membrane was isolated from porcine spermatozoa by the procedure of Lunstra, Clegg &amp; Morré (1974). Briefly, sperm-rich semen was filtered at the time of collection through Miracloth (Chicopee Mills, Inc., New York, N.Y.) and then
Radiolabeled meta-iodobenzylguanidine: pharmacology and clinical studies. (1986)

Much was known of the pharmacology of meta-iodobenzylguanidine (MIBG) before its clinical use, but we have since learned a good deal more about the metabolic distribution and fate of this radiopharmaceutical. And, as is the nature of science, more is yet to be discovered. This communication reviews what is known about the pharmacology of radiolabeled MIBG and how this pharmacology affects the clinical studies that use the agent.
Heating, ventilation, air conditioning and refrigeration system (2023)

A heating, ventilation, air conditioning and refrigeration (HVAC/R) system includes a sorption circuit including a heat absorption heat exchanger in fluid communication with a primary fluid flow source such that a primary fluid flow from is directed therethrough. The heat absorption heat exchanger is configured to exchange thermal energy between the primary fluid flow and a secondary fluid flow. A sorption heat exchanger includes a sorbent material to adsorb or absorb the primary fluid flow, generating thermal energy. The sorption heat exchanger is configured to transfer the generated thermal energy to a tertiary fluid flow. A heat exchange circuit is in fluid communication with the sorption circuit and includes a control valves connected to both the secondary fluid flow and the tertiary fluid flow configured to selectably direct the secondary fluid flow and/or the tertiary fluid flow to a conditioning heat exchanger or an ambient heat exchanger.
The importance of preconditioners in fast Poisson-based iterative reconstruction algorithms for SPECT (2002)

We study the effects of different preconditioners on Poisson-based iterative reconstruction algorithms. Preconditioners are linear transformations that map the image solution space for the reconstruction problem into a space where the likelihood function can be more efficiently optimized. We apply preconditioners to conjugate gradient (CG) algorithms seeking to optimize the Poisson log likelihood function for SPECT. We show that, without a preconditioner, such algorithms may converge more slowly than the ML-EM algorithm. Previous research has applied a preconditioner that depends on the current iteration's image estimate. However, these algorithms do not generate conjugate step directions and do not obtain the full benefit of the CG algorithm's speed. We propose a preconditioner that depends only on the measured projection data and remains constant with each iteration, thus generating nearly conjugate step directions. We show that our method optimizes the log likelihood function more efficiently than the previously proposed methods. We also show that, if the measured projection data contains few zero or near-zero projection bins, the Poisson CG algorithms have convergence rates comparable with those from weighted least-squares (WLS-CG) algorithms. We conclude that the performance of Poisson CG algorithms depends heavily on the preconditioner chosen, and that they can be made competitive with WLS-CG by manipulation of the preconditioners.
Synthesis and luminescence properties of a Cyan‐blue thiosilicate‐based Phosphor SrSi2S5:Eu2+ (2010)

Abstract A series of Sr‐Si‐S compounds was synthesized using an advanced chemical method in which the use of one solution‐based process uniformly dispersed the Eu2+ activators in the host crystals, to find new compositions that would suit phosphor applications. Particular focus was given to the Si‐rich region. This led to the synthesis of a single‐phase compound that showed an unknown X‐ray diffraction pattern. This compound had a composition close to that of SrSi2S5. When this compound is activated with Eu2+ (SrSi2S5:Eu2+), it shows a cyan‐blue emission with a main luminescence peak at 495 nm. This emission is excited by wavelengths of 250–440 nm and has a maximum excitation at 350 nm.

Effect of Pimozide on Positive and Negative Symptoms in Schizophrenic Patients: Are Negative Symptoms State Dependent? (1987)

In a double-blind, placebo-controlled trial of treatment with the neuroleptic pimozide, negative symptoms improved in schizophrenic patients who showed an antipsychotic response. Furthermore, there was a significant positive correlation between changes in positive and negative symptoms for the group as a whole, including both pimozide responders and nonresponders. In our patient sample, neuroleptic treatment did not exert a differential effect on the positive and negative symptoms of schizophrenia. It is conceivable that negative symptoms are state dependent and may become neuroleptic nonresponsive over time just as positive symptoms do in some chronic patients.
Experimental parametric analysis of an energy harvester based on highly nonlinear solitary waves (2016)

We investigate experimentally five different designs of an energy harvester based on mechanical vibration and highly nonlinear solitary waves. The harvester consists of a metamaterial formed by granular chains, an oscillator that taps the metamaterial, a solid in contact with the metamaterial, and a piezoelectric element glued to the solid. The overall principle is that the oscillator taps the metamaterial and creates a train of solitary waves along each chain. At the interface between the chains and the solid, part of the acoustic energy refracts into the solid where it coalesces at a point and triggers the vibration of the solid. Here, a transducer converts the focalized stress wave and the waves generated by the reverberation with the edges into electric potential. In the study presented in this article, we evaluate the effect of certain harvester parameters on the amount of energy that can be extracted. We considered five different designs by changing the oscillator, the dimension of the array, the solid material, and the transducer boundary condition. For each design we computed the power density, and we found that the density obtained with the best design is four orders of magnitude higher than the worst design.

Electroporation-Facilitated Delivery of Plasmid DNA in Skeletal Muscle: Plasmid Dependence of Muscle Damage and Effect of Poloxamer 188 (2001)

Electroporation has been reported to facilitate naked DNA gene transfer in skeletal muscle, but has also been implicated in the pathogenesis of electrical injuries. To assess the effects of electroporation on gene transfer, mouse quadriceps muscles were injected with the luciferase reporter plasmid VR1255 and electroporated with caliper electrodes. Intramuscular luciferase expression was increased 10- to 70-fold by electroporation, depending on the DNA dose and injection volume used. In the absence of plasmid DNA injection, electroporation of quadriceps muscles resulted in rapid elevations in serum creatine phosphokinase activity, but did not elicit visible muscle damage. However, in muscles injected with plasmid DNA and electroporated, visible lesions consistently developed in the areas proximal to electrode placement when field strengths optimal for gene transfer (300 volts/cm) were applied. The development of muscle lesions was independent of plasmid transgene expression and required the presence of plasmid in the muscle during electroporation. Co-injection of poloxamer 188 (pluronic F68) with VR1255 substantially reduced elevations in serum creatine phosphokinase activity following electroporation, but did not inhibit the development of muscle lesions. In non-electroporated muscles, co-injection of poloxamer 188 increased luciferase expression threefold. Poloxamer 188 may thus constitute a useful excipient for intramuscular delivery of naked DNA.
