Congenital hyperinsulinism disorders: Genetic and clinical characteristics (2019)

Congenital hyperinsulinism (HI) is the most frequent cause of persistent hypoglycemia in infants and children. Delays in diagnosis and initiation of appropriate treatment contribute to a high risk of neurocognitive impairment. HI represents a heterogeneous group of disorders characterized by dysregulated insulin secretion by the pancreatic beta cells, which in utero, may result in somatic overgrowth. There are at least nine known monogenic forms of HI as well as several syndromic forms. Molecular diagnosis allows for prediction of responsiveness to medical treatment and likelihood of surgically-curable focal hyperinsulinism. Timely genetic mutation analysis has thus become standard of care. However, despite significant advances in our understanding of the molecular basis of this disorder, the number of patients without an identified genetic diagnosis remains high, suggesting that there are likely additional genetic loci that have yet to be discovered.
Identification of a meristem L1 layer-specific gene in Arabidopsis that is expressed during embryonic pattern formation and defines a new class of homeobox genes. (1996)

Homeobox genes are master regulatory genes that specify the body plan and control development of many eukaryotic organisms, including plants. We isolated and characterized a cDNA designated ATML1 (for Arabidopsis thaliana meristem L1 layer) that encodes a novel homeodomain protein. The ATML1 protein shares high sequence homology inside and outside of the homeodomain with both the Phalaenopsis O39 and the Arabidopsis GLABRA2 (GL2) homeodomain proteins, which together define a new class of plant homeodomain-containing proteins, designated HD-GL2. The ATML1 gene was first expressed in the apical cell after the first asymmetric division of the zygote and continued to be expressed in all proembryo cells until the eight-cell stage. In the 16-cell proembryo, the ATML1 gene showed a distinct pattern of expression, with its mRNA becoming restricted to the protoderm. In the torpedo stage of embryo development, ATML1 mRNA disappeared altogether but reappeared later only in the L1 layer of the shoot apical meristem in the mature embryo. After germination, this L1 layer-specific pattern of expression was maintained in the vegetative shoot apical meristem, inflorescence, and floral meristems, as well as in the young floral organ primordia. Finally, ATML1 mRNA accumulated in the protoderm of the ovule primordia and integuments and gradually became restricted in its expression to the endothelium surrounding the embryo sac. We propose that ATML1 may be involved in setting up morphogenetic boundaries of positional information necessary for controlling cell specification and pattern formation. In addition, ATML1 provides an early molecular marker for the establishment of both apical-basal and radial patterns during plant embryogenesis.
An IgG human monoclonal antibody that reacts with HIV-1/GP120, inhibits virus binding to cells, and neutralizes infection (1991)

A human mAb (HmAb) termed F105 was obtained by fusion of antibody-producing EBV-transformed cells with the HMMA2.11TG/O cell line. F105 is an IgG1 kappa antibody that binds to the surfaces of cells infected with all HIV-1 strains tested: MN, RF, IIIB, and SF2, but not uninfected cells. The HmAb immunoprecipitates GP120 from all four strains. F105 does not react with denatured GP120 on Western blots, but does react with viral lysates and purified GP120 dotted onto nitrocellulose filter paper under nondenaturing conditions. rGP120 from SF2 and soluble rCD4 inhibit antibody binding to infected cells in a dose-dependent manner. F105 inhibits the binding of free, infectious virions to uninfected HT-H9 cells with 50% of maximal (100%) inhibition at approximately 1 microgram/ml. F105 inhibits infection of HT-H9 cells by 100 tissue culture infective dose 50% units of MN and IIIB strains with 50% inhibition at concentrations of HmAb readily achievable in man. It appears that the F105 HmAb reacts with a conformationally defined epitope on HIV-1/GP120 that is exposed on the free virion and is important for binding to the cell surface by the virion. The epitope, which is immunogenic in humans, appears to be within, or topographically near, the CD4-binding site. F105 and the F105 epitope are potentially useful in therapy and in the design of peptide or anti-Id based vaccines; monitoring of the expression of the Id may prove useful in evaluating immune responses in infected individuals or vaccinated volunteers.
Effects of saliva collection using cotton swabs on melatonin enzyme immunoassay (2011)

Our findings indicate an interference effect of cotton swabs on the assay result of salivary melatonin at lower melatonin level. Cotton-based collection devices might, thus, not be suitable for assessment of DLMO.
Metabolic Regulation of T Lymphocytes (2013)

T cell activation leads to dramatic shifts in cell metabolism to protect against pathogens and to orchestrate the action of other immune cells. Quiescent T cells require predominantly ATP-generating processes, whereas proliferating effector T cells require high metabolic flux through growth-promoting pathways. Further, functionally distinct T cell subsets require distinct energetic and biosynthetic pathways to support their specific functional needs. Pathways that control immune cell function and metabolism are intimately linked, and changes in cell metabolism at both the cell and system levels have been shown to enhance or suppress specific T cell functions. As a result of these findings, cell metabolism is now appreciated as a key regulator of T cell function specification and fate. This review discusses the role of cellular metabolism in T cell development, activation, differentiation, and function to highlight the clinical relevance and opportunities for therapeutic interventions that may be used to disrupt immune pathogenesis.
Characterization of [3H]‐CGP54626A binding to heterodimeric GABAB receptors stably expressed in mammalian cells (2000)

Functional human GABA(B(1a,2)) and GABA(B(1b,2)) receptors have been stably expressed in mammalian CHO K1 cells. Detailed characterization of GABA(B) ligand binding at each of the receptors has been compared using [(3)H]-CGP54626A. In cell membranes fractions, [(3)H]-CGP54626A bound to a single site with a K(D) of 1. 51+/-1.12 nM, B(max) of 2.02+/-0.17 pmoles mg protein(-1) and 0. 86+/-0.20 nM, B(max) of 5.19+/-0.57 pmoles mg protein(-1) for GABA(B(1a,2)) and GABA(B(1b,2)) respectively. In competition binding assays the rank order was identical for both GABA(B) receptors. For known GABA(B) agonists the rank order was CGP27492>SKF97541=CGP46381>GABA>Baclofen and for GABA(B) antagonists the rank order was CGP54262A>CGP55845>CGP52432>SCH 50911>CGP51176>CGP36742=CGP35348 > or =2-OH Saclofen > or =ABPA. The allosteric effect of calcium cations was also investigated. The effect of removal of CaCl(2) from the binding assay conditions was ligand dependent to either cause a decrease in ligand affinity or to have no significant effect. However, these effects were similar for both GABA(B) receptors. A whole cell, scintillation proximity binding assay was used to determine agonist affinity at exclusively heterodimeric GABA(B) receptors. In competition assays, the rank order was the same for both GABA(B(1a,2)) and GABA(B(1b,2)) and consistent with that seen with cell membrane fractions. These data suggest that, in terms of ligand binding, the currently identified isoforms of the GABA(B) receptor are pharmacologically indistinguishable.
A universal strategy for regulating mRNA translation in prokaryotic and eukaryotic cells (2015)

We describe a simple strategy to control mRNA translation in both prokaryotic and eukaryotic cells which relies on a unique protein-RNA interaction. Specifically, we used the Pumilio/FBF (PUF) protein to repress translation by binding in between the ribosome binding site (RBS) and the start codon (in Escherichia coli), or by binding to the 5' untranslated region of target mRNAs (in mammalian cells). The design principle is straightforward, the extent of translational repression can be tuned and the regulator is genetically encoded, enabling the construction of artificial signal cascades. We demonstrate that this approach can also be used to regulate polycistronic mRNAs; such regulation has rarely been achieved in previous reports. Since the regulator used in this study is a modular RNA-binding protein, which can be engineered to target different 8-nucleotide RNA sequences, our strategy could be used in the future to target endogenous mRNAs for regulating metabolic flows and signaling pathways in both prokaryotic and eukaryotic cells.

Omalizumab diminished clinical symptoms and signs of chronic idiopathic urticaria in patients who had remained symptomatic despite the use of approved doses of H-antihistamines. (Funded by Genentech and Novartis Pharma; ClinicalTrials.gov number, NCT01292473.).
Double antiresonant hollow core fiber – guidance in the deep ultraviolet by modified tunneling leaky modes (2014)

Guiding light inside the hollow cores of microstructured optical fibers is a major research field within fiber optics. However, most of current fibers reveal limited spectral operation ranges between the mid-visible and the infrared and rely on complicated microstructures. Here we report on a new type of hollow-core fiber, showing for the first time distinct transmission windows between the deep ultraviolet and the near infrared. The fiber, guiding in a single mode, operates by the central core mode being anti-resonant to adjacent modes, leading to a novel modified tunneling leaky mode. The fiber design is straightforward to implement and reveals beneficial features such as preselecting the lowest loss mode (Gaussian-like or donut-shaped mode). Fibers with such a unique combination of attributes allow accessing the extremely important deep-UV range with Gaussian-like mode quality and may pave the way for new discoveries in biophotonics, multispectral spectroscopy, photo-initiated chemistry or ultrashort pulse delivery.
Factors Affecting the Efficiency of Nuclear Transplantation in the Rabbit Embryo1 (1990)

Procedures to improve nuclear transplantation efficiency in the rabbit were evaluated. We report the influence of recipient oocyte age on the different steps of nuclear transplantation. The effect of multiple pulses and the influence of manipulation medium and cytochalasin B in the post-fusion/activation medium on activation and development were studied. Recently ovulated oocytes were enucleated at a higher rate (60%) than aged oocytes (3%, p less than 0.005); they also fused at a higher rate (85% vs. 26%, p less than 0.001). Activation was low with freshly ovulated oocytes compared to aged oocytes (3% vs. 37%, respectively; p less than 0.005), but was increased by using multiple pulses (85% vs. 68%, p less than 0.05). Multiple pulses also improved development to blastocysts (48% vs. 5%, p less than 0.001). Incubation of oocytes in a bicarbonate-buffered medium with 10% fetal calf serum for manipulation also enhanced rates of activation (100% vs. 89%, p less than 0.05) and development of oocytes to blastocysts (77% vs. 26%, p less than 0.001). Furthermore, 7.5 micrograms/ml cytochalasin B in the post-fusion/activation medium increased activation rates (78% vs. 50%, p less than 0.05) and development to blastocysts of manipulated embryos (46% vs. 11%, p less than 0.001). When the above modifications were applied, 10% (23/230) of the total nuclear transplant embryos (8-16-cell-stage donor nuclei) or 21% (23/110) of those transferred to recipients developed to offspring, rates similar to the development of nonmanipulated control embryos (10%, 4/41, p greater than 0.1).
<i>CFTR</i> Inactivation by Lentiviral Vector-mediated RNA Interference and CRISPR-Cas9 Genome Editing in Human Airway Epithelial Cells (2015)

We generated CFTR inactivated cell lines and demonstrated that CRISPR-Cas9 vectorised in a single LVV efficiently promotes CFTR inactivation in primary HAECs. These results provide a new protocol to engineer CF primary epithelia with their isogenic controls and pave the way for manipulation of CFTR expression in these cultures.
Therapeutic hypothermia for acute liver failure (2009)

Cerebral edema is a potentially life-threatening complication of acute liver failure, the syndrome of abrupt loss of liver function in a patient with a previously healthy liver. Although the prevalence of cerebral edema appears to be decreasing, patients with rapidly progressive (hyperacute) liver failure, such as after acetaminophen overdose, remain at highest risk. In severe cases of cerebral edema, intracranial hypertension develops and leads to brain death after brainstem herniation or to anoxic brain injury and permanent neurologic impairment. Intracranial hypertension in patients with acute liver failure often can be temporarily controlled by manipulating body position, increasing the degree of sedation, and increasing blood osmolarity through pharmacologic means. However, these maneuvers often postpone, but do not eliminate, the risk of brainstem herniation unless orthotopic liver transplantation or spontaneous liver regeneration follows in short order. To buy time, the induction of therapeutic hypothermia (core temperature 32 degrees C-35 degrees C) has been shown to effectively bridge patients to transplant. Similar to the experience in patients with cerebral edema after other neurologic insults, hypothermia reduces cerebral edema and intracranial hypertension in patients with acute liver failure by decreasing splanchnic ammonia production, restoring normal regulation of cerebral hemodynamics, and lowering oxidative metabolism within the brain. Hypothermia may also ameliorate the degree of liver injury. Hypothermia has not been adequately studied for its safety and theoretically may increase the risk of infection, cardiac dysrhythmias, and bleeding, all complications independently associated with acute liver failure. Therefore, although an ample body of experimental and human data provides a rationale for the use of therapeutic hypothermia in patients with acute liver failure, multicenter, randomized, controlled clinical trials are needed to confirm that hypothermia secures brain viability and improves survival without causing harm.
Studies on the Safety of Glucose and Paraben-Containing Neostigmine for Intrathecal Administration (1997)

Initial toxicity testing of neostigmine for intrathecal (IT) injection was performed with preservative-free isobaric solution, yet currently available formulations contain the preservatives methyl- and propylparaben and are usually mixed with glucose to yield hyperbaric solutions. Since it has been proposed that preservatives and hyperbaricity increase the risk of neurotoxicity after IT injection, we examined the safety of chronically administered IT neostigmine containing these additives in sheep and rats. Rats receiving daily IT injections of glucose alone or of glucose with preservative-containing neostigmine, 5 and 10 micro g, exhibited dose-related antinociception, tremor, and rigidity. In comparison to our previously published study of neostigmine injection in solution without glucose, rats receiving IT neostigmine with glucose displayed less rigidity, tremor, and salivation. Sheep receiving daily injection of glucose alone or with preservative-containing neostigmine, 1 mg, for 14 days exhibited no histologic evidence of neurotoxicity, nor did they exhibit abnormalities in cerebrospinal fluid chemistry aside from those caused by inflammation. Spinal cord histologic examination in both species revealed fibrosis and inflammation secondary to the catheter without evidence of neuronal damage. These studies support the safety of paraben- and glucose-containing IT neostigmine. (Anesth Analg 1997;85:317-23)
Regulation of Class II MHC Expression (1996)

The class II genes of the major histocompatibility complex (MHC) encode the alpha/beta heterodimeric glycoproteins that play a critical role in the induction of immune responses through presentation of processed antigen to CD4+ T lymphocytes. The constitutive expression of class II MHC antigens is restricted primarily to B cells, dendritic cells, thymic epithelium, and macrophages, although a wide variety of other cell types can be induced to express class II antigens after exposure to cytokines. The appropriate constitutive and inducible te constitutive and inducible expression of class II MHC antigens is essential for normal immune function; thus it is not surprising that aberrant expression on cell types normally class II MHC negative has been correlated with various autoimmune disorders, and lack of expression results in a severe combined immunodeficiency disorder called bare lymphocyte syndrome (BLS). In this review, we discuss the agents that both induce and inhibit class II MHC expression, the function of class II MHC antigens with an emphasis on the ability of these proteins to act as signal transducing molecules, and the molecular regulation of class II MHC expression.
Specific Serological Diagnosis of Leprosy with a Recombinant Mycobacterium leprae Protein Purified from a Rapidly Growing Mycobacterial Host (1998)

In this report we demonstrate the utility of an monoclonal antibody inhibition enzyme-linked immunosorbent assay based on the Mycobacterium leprae 35-kDa protein, purified from the rapidly growing host Mycobacterium smegmatis, for the serodiagnosis of multibacillary leprosy. The assay proved highly specific (97.5%) and sensitive (90%) and compared favorably with two other established methods routinely utilized for leprosy serodiagnosis.
SOAF: An Architectural Framework for Service Definition and Realization (2006)

Service oriented architecture (SOA) is an approach for building distributed systems that deliver application functionality as a set of self-contained business-aligned services with well-defined and discoverable interfaces. This paper presents a systematic and architecture-centric framework, named service oriented architecture framework (SOAF), to ease the definition, the design and the realization of SOA in order to achieve a better business and IT alignment. The proposed framework is business-process centric and comprises a set of structured activities grouped in five phases. It incorporates a range of techniques and guidelines for systematically identifying services, deciding service granularity and modeling services while integrating existing operational/legacy systems. The results from a pilot validation of SOAF for SOA enablement of a realistic securities trading application are presented. Best practices and lessons learned are also discussed
Set-oriented mining for association rules in relational databases (2002)

Describe set-oriented algorithms for mining association rules. Such algorithms imply performing multiple joins and may appear to be inherently less efficient than special-purpose algorithms. We develop new algorithms that can be expressed as SQL queries, and discuss the optimization of these algorithms. After analytical evaluation, an algorithm named SETM emerges as the algorithm of choice. SETM uses only simple database primitives, viz. sorting and merge-scan join. SETM is simple, fast and stable over the range of parameter values. The major contribution of this paper is that it shows that at least some aspects of data mining can be carried out by using general query languages such as SQL, rather than by developing specialized black-box algorithms. The set-oriented nature of SETM facilitates the development of extensions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Enhancement of Brain L‐Dopa Concentration with α‐Chymotrypsin (1973)

ABSTRACT: α‐Chymotrypsin (5 mg per kg per dose) plus L‐dopa (250 mg per kg per dose) was administered orally to 15 mice in a series of 5 feedings during a 26‐hour period. There was a 2.35‐fold increase in the brain concentration of L‐dopa compared with the increase in 5 mice given L‐dopa alone. It is suggested that oral administration of α‐chymotrypsin in combination with L‐dopa might be of clinical value in the management of Parkinson's disease.
A method for estimating the “position accuracy” of acoustic fish tags (2002)

Acoustic tag systems have been used for many years to study the behavior of fish in specific areas of interest. In particular tag systems are being used successfully to study the behavior of downstream migrating salmon smolts ( Oncorhynchus spp.) as they approach hydro-electric dams. While field studies have demonstrated the potential for acoustic tag systems, little has been done to quantify their performance. This paper develops a method for predicting the accuracy of the “position estimates” provided by acoustic tag systems. General expressions are developed that can be applied to any particular deployment of a tag system which lead onto a method for the direct calculation of the “position error” as a function of hydrophone geometry, standard deviation of the signal arrival times, and the inaccuracies in the assumed sound velocities. This method is independent of the algorithm used to determine the position solution. Using the methods of analysis developed here some specific examples are presented that provide general guidelines that should be followed to achieve good performance when deploying an acoustic tag system.
