Defining compulsive exercise in eating disorders: acknowledging the exercise paradox and exercise obsessions (2019)

Recently Dittmer et al. (JED 6:1-9, 2018). suggested a transdiagnostic definition and a clinical assessment for compulsive exercise in adolescents and adults with eating disorders. In this letter to the editor, we extend the transdiagnostic bridge to the DSM-5-criteria for obsessive-compulsive disorders and hence raise the issue of exercise obsession without compulsive exercise actions. We argue that, at least among persons with bulimia nervosa or binge eating disorders, a belief in the need to exercise to control food, weight and shape, does not necessarily imply that the actual exercise behaviour is excessive in nature. In our opinion, the high scores displayed on compulsive exercise screening instruments is therefore an exercise paradox. This paradox may call attention to the fact that because such obsessions can impair quality of life, they need to be addressed in the clinical evaluation and treatment. Therefore, we suggest adding "exercise obsession" as a fourth subtype of compulsive exercise.
2-Aza-1,3-butadiene Derivatives Featuring an Anthracene or Pyrene Unit:  Highly Selective Colorimetric and Fluorescent Signaling of Cu2+Cation (2006)

[Structure: see text] A new probe based on an anthryl derivative bearing an azadiene side chain selectively senses Cu2+ in acetonitrile through two different channels: the yellow-to-orange color change and a remarkable enhancement of the fluorescence, whereas the pyrenyl analogous behaves as a fluorescent sensor for Cu2+ and Hg2+ in aqueous environment.
Reduced content of connexin43 gap junctions in ventricular myocardium from hypertrophied and ischemic human hearts. (1993)

Gap junctions in normal adult human working ventricular myocardium occupy an area of 0.0051 micron2/micron3 myocyte volume. This surface area is reduced in ventricular myocardium from hearts subject to chronic hypertrophy and ischemia, despite a normal number of intercellular abutments, and this alteration may contribute to abnormal impulse propagation in these hearts.
An oral selective M3 cholinergic receptor antagonist in COPD (2006)

Cholinergic antagonists have been used since the early 1900s as bronchodilators for chronic obstructive pulmonary disease (COPD). The present study investigated whether an oral muscarinic M3-selective anticholinergic agent (OrM3) would provide an improved therapeutic advantage compared with an inhaled anticholinergic agent in patients with COPD. A 6-week, multicentre, randomised, placebo- and active-controlled, parallel-group study was performed at 56 sites in the USA. In total, 412 male and female patients (aged 35-86 yrs) with a clinical history consistent with COPD were randomised to receive OrM3 0.5, 2, 3 or 4 mg orally once daily, ipratropium bromide 36 mug by inhalation four times daily or placebo. OrM3 demonstrated a significant dose-related improvement in serial forced expiratory volume in one second and a trend for dose-related improvement in patient-reported symptoms compared with placebo. However, at a dose that provided efficacy less than that of ipratropium, the incidence of dose-related, mechanism-based side-effects for OrM3 exceeded those observed for ipratropium. In patients with chronic obstructive pulmonary disease, the oral M3-selective agent did not offer a therapeutic advantage over inhaled ipratropium. These results do not support the hypothesis that high selectivity for muscarinic M3 receptors over airway neuronal M2 receptors will represent a more effective therapy than current inhaled anticholinergics in obstructive airway disease.
Accumulation of labelled vitamin B12 in some transplanted tumours (1968)

Abstract The accumulation of labelled vitamin B 12 in four different kinds of transplanted tumour was studied using whole‐body autoradiography and impulse counting. The tumours were 90 Sr‐induced soft fibroblastic osteosarcomas, spontaneous mammary carcinomas, Ehrlich ascites and Moloney virus‐induced tumours. The 90 Sr‐induced soft sarcoma, which was the most rapidly growing tumour, showed the greatest uptake of radio‐B 12 , the concentration being higher than in any normal tissue. In all tumours the radioactivity was localized to the peripheral, still actively growing parts. It is suggested that a connection exists between growth rate and accumulation of B 12 and that B 12 is needed for rapid cell multiplication.
The Chemistry of TALSPEAK: A Review of the Science (2014)

The TALSPEAK Process (Trivalent Actinide Lanthanide Separation with Phosphorus-Reagent Extraction from Aqueous Komplexes) was originally developed at Oak Ridge National Laboratory by B. Weaver and F.A. Kappelmann in the 1960s. It was envisioned initially as an alternative to the TRAMEX process (selective extraction of trivalent actinides by tertiary or quaternary amines over fission product lanthanides from concentrated LiCl solutions). TALSPEAK proposed the selective extraction of trivalent lanthanides away from the actinides, which are retained in the aqueous phase as aminopolycarboxylate complexes. After several decades of research and development, the conventional TALSPEAK process (based on di-(2-ethylhexyl) phosphoric acid (extractant) in 1,4-di-isopropylbenzene (diluent) and a concentrated lactate buffer containing diethylenetriamine-N,N,N’,N”,N”-pentaacetic acid (actinide-selective holdback reagent)) has become a widely recognized benchmark for advanced aqueous partitioning of the trivalent 4f/5f elements. TALSPEAK aqueous chemistry has also been utilized to selectively strip actinides (Reverse TALSPEAK) with some notable success. Under ideal conditions, conventional TALSPEAK separates Am3+ from Nd3+ (the usual limiting pair) with a single-stage separation factor of about 100; both lighter and heavier lanthanides are more completely separated from Am3+. Despite this apparent efficiency, TALSPEAK has not seen enthusiastic adoption for advanced partitioning of nuclear fuels at process scale for two principle reasons: first, all adaptations of TALSPEAK chemistry to process scale applications require rigid pH control within a narrow range of pH, and second, phase-transfer kinetics are often slower than ideal. To compensate for these effects, high concentrations of the buffer (0.5–2 M H/Na lactate) are required. Acknowledgement of these complications in TALSPEAK process development has inspired significant research activities dedicated to improving understanding of the basic chemistry that controls TALSPEAK (and related processes based on the application of actinide-selective holdback reagents). In the following report, advances in understanding of the fundamental chemistry of TALSPEAK that have been reported during the past decade will be reviewed and discussed.
Unexpected Density Fluctuations in Jammed Disordered Sphere Packings (2005)

We computationally study jammed disordered hard-sphere packings as large as a million particles. We show that the packings are saturated and hyperuniform, i.e., that local density fluctuations grow only as a logarithmically augmented surface area rather than the volume of the window. The structure factor shows an unusual nonanalytic linear dependence near the origin, S(k) approximately |k|. In addition to exponentially damped oscillations seen in liquids, this implies a weak power-law tail in the total correlation function, h(r) approximately -r(-4), and a long-ranged direct correlation function c(r).
Structural applications of mechanical alloying; Proceedings of the ASM International Conference, Myrtle Beach, SC, Mar. 27-29, 1990 (1990)

The present conference on mechanically alloyed (MA) products discusses their aerospace and industrial applications, the design and isothermal forging of Ni-base oxide dispersion-strengthened (ODS) superalloys, the microstructure and tensile properties of ODS ferritic alloys, the high temperature corrosion resistance of MA refractory products, the mechanical properties of novel MA Fe-based ODS alloys, and dispersoids in MA metals. Also discussed are MA Al-alloys for aircraft applications, the microstructure and properties of MA Al-Mn, the MA processing of the Ti-Al system, the origin of the strength of MA Al alloys, the interaction of Al with SiC during MA processing, the synthesis of chromium silicide via MA, and the MA production of 'TiC-steel'.
Identification of an autoantibody panel to separate lung cancer from smokers and nonsmokers (2010)

A pattern of autoantibody reactivity to TAAs may distinguish patients with lung cancer versus smokers with normal CTs, stable solid nodules, ground glass opacities, or normal healthy never smokers.
Recent Advances in Seismocardiography (2019)

Cardiovascular disease is a major cause of death worldwide. New diagnostic tools are needed to provide early detection and intervention to reduce mortality and increase both the duration and quality of life for patients with heart disease. Seismocardiography (SCG) is a technique for noninvasive evaluation of cardiac activity. However, the complexity of SCG signals introduced challenges in SCG studies. Renewed interest in investigating the utility of SCG accelerated in recent years and benefited from new advances in low-cost lightweight sensors, and signal processing and machine learning methods. Recent studies demonstrated the potential clinical utility of SCG signals for the detection and monitoring of certain cardiovascular conditions. While some studies focused on investigating the genesis of SCG signals and their clinical applications, others focused on developing proper signal processing algorithms for noise reduction, and SCG signal feature extraction and classification. This paper reviews the recent advances in the field of SCG.
Analysis of Polypeptides of the Tree Shrew (Tupaia) Herpesvirus by Gel Electrophoresis (1982)

The virion polypeptide composition of three independently isolated tree shrew herpesviruses (THV) was analysed by SDS-polyacrylamide slab gel electrophoresis and by a two-dimensional technique using isoelectric focusing. Two of the virus isolates analysed were from malignant tumours; the other isolate (THV, strain 1) was from an apparently healthy animal. The polypeptide patterns of the three purified Tupaia herpesvirus isolates were remarkably similar, each consisting of at least 35 polypeptides ranging in mol. wt. from 12,000 to 230,000. Whilst the majority of analogous polypeptides of the three viruses were of indistinguishable electrophoretic mobility, some (e.g. polypeptides of 82K to 86K) showed small differences in apparent mol. wt. which were characteristic of the virus strain. Comparative SDS-polyacrylamide gel electrophoresis made it possible to distinguish the Tupaia herpesvirus isolates from each other. At least five glycoproteins were found in purified THV virions. The two-dimensional electropherograms revealed at least 47 discernible protein spots, some of which were specific for a given THV isolate and which were detectable even in lysates of THV-infected cells.
Metal Chelation and Inhibition of Bacterial Growth in Tissue Abscesses (2008)

Bacterial infection often results in the formation of tissue abscesses, which represent the primary site of interaction between invading bacteria and the innate immune system. We identify the host protein calprotectin as a neutrophil-dependent factor expressed inside Staphylococcus aureus abscesses. Neutrophil-derived calprotectin inhibited S. aureus growth through chelation of nutrient Mn2+ and Zn2+: an activity that results in reprogramming of the bacterial transcriptome. The abscesses of mice lacking calprotectin were enriched in metal, and staphylococcal proliferation was enhanced in these metal-rich abscesses. These results demonstrate that calprotectin is a critical factor in the innate immune response to infection and define metal chelation as a strategy for inhibiting microbial growth inside abscessed tissue.
In infection with Schistosoma mansoni, B cells are required for T helper type 2 cell responses but not for granuloma formation (1997)

The immune response and immunopathologic manifestations in schistosomiasis are largely dependent on Ag-specific CD4+ Th cells. In turn, the stimulatory/regulatory function of the Th cells is dependent on signals emanating from accessory cells. B cells are capable of functioning as accessory cells, and their role in experimental murine schistosomiasis was investigated by using mice with targeted mutations in the J(H) locus. This phenotype results in the absence of B cells and of Ab production. After 7.5- to 8-wk infections, mesenteric lymph node cells from the JHD B-less mice displayed lower proliferative responses to schistosomal egg Ag than did cells from infected control mice. Most importantly, compared with cells from controls, egg Ag-stimulated JHD lymph node cells produced significantly higher amounts of the Th1 response-associated cytokines IFN-gamma and IL-12, while their production of the Th2-type cytokines IL-4 and IL-10 was dramatically reduced or undetectable. Similarly, irradiated splenocytes from uninfected JHD mice, used as APC, elicited significantly stronger Th1 and weaker Th2 responses from egg Ag-specific CD4+ Th cells than splenocytes from control mice. Despite these sharply contrasting cytokine profiles, there were no significant differences either in the size and composition of the resulting egg granulomas or in the number of deposited eggs in the livers of infected JHD vs control mice. Taken together, the findings in the JHD mouse reflect an impairment in the ability to mount a Th2 response, which translates into a loss of the Th1 to Th2 switch characteristically seen in normal schistosome-infected mice. These results suggest that B cells promote Th2-type responses, and that typical granulomatous responses proceed in their absence.
Localization of interferon-gamma and Ia-antigen in T cell line-mediated experimental autoimmune encephalomyelitis. (1993)

This study reports the cellular localization of interferon-gamma (IFN-gamma) and MHC class II antigen (Ia) in the spinal cord of rats with experimental autoimmune encephalomyelitis induced by adoptive transfer of myelin basic protein-specific T cells. Numerous IFN-gamma-positive cells, stained with two different monoclonal antibodies against IFN-gamma, were present from days 3 to 7 after cell transfer. Their number was greatly reduced on day 10. A subpopulation of T cells was IFN-gamma positive. Moreover, a large number of ED1-positive macrophages contained IFN-gamma immunoreactivity. The transient presence of immune cells containing IFN-gamma immunoreactivity in experimental autoimmune encephalomyelitis suggests a pathogenic role of this cytokine in immune-mediated demyelination of the central nervous system.
Binding of Human Plasma Sialoglycoproteins by the B Cell-specific Lectin CD22 (1995)

CD22 is a cell-surface receptor of resting mature B cells that recognizes sialic acid (Sia) in the natural structure Sia alpha 2-6Gal beta 1-4GlcNAc (Powell, L. D., Jain, R. K., Matta, K. L., Sabesan, S., and Varki, A. (1995) J. Biol. Chem. 270, 7523-7532). Human umbilical vein endothelial cells (HEC) treated with inflammatory cytokines such as tumor necrosis factor-alpha (TNF-alpha) display increases in cell-surface CD22 ligands, caused by increased expression of the enzyme beta-galactoside alpha 2,6-sialyltransferase (Hanasaki, K., Varki, A., Stamenkovic, I., and Bevilacqua, M. P. (1994) J. Biol. Chem. 269, 10637-10643; Hanasaki, K., Varki, A., and Powell, L. D. (1995) J. Biol Chem. 270, 7533-7542). Thus, CD22 could direct potential interactions between mature B cells and endothelial cells during inflammatory states. However, this would have to occur in the presence of blood plasma, which contains many sialoglycoproteins known to carry alpha 2-6-linked sialic acids. We show here that human plasma can indeed inhibit Sia-dependent binding of a recombinant soluble chimeric form of human CD22 (CD22Rg) to TNF-alpha activated HEC. Affinity adsorption of individual human plasma samples with immobilized CD22Rg showed that, of the numerous alpha 2-6-sialic acid containing glycoproteins in plasma, only three polypeptides with apparent molecular mass (under reducing conditions) of 74, 44, and 25 kDa bound, and were specifically eluted with alpha 2-6-sialyllactose. NH2-terminal amino acid sequencing of these high affinity CD22 ligands revealed that they are subunits of immunoglobulin M (IgM) and haptoglobin. Purified human IgM from pooled human plasma can be quantitatively bound by CD22Rg, and binding is blocked by alpha 2-6-sialyllactose, but not by alpha 2-3-sialyllactose. Pretreatment by sialidase or by mild periodate oxidation of sialic acid side chains abolishes these interactions. IgM at physiological concentrations also inhibits CD22Rg binding to TNF-alpha-activated HEC in a manner dependent not only upon its sialylation but also requiring its intact multimeric structure. These data show that CD22 is capable of highly selective recognition of certain multimeric plasma sialoglycoproteins that carry alpha 2-6-linked sialic acids. Notably, the two proteins that are selectively recognized are known to be involved in immune and inflammatory responses. Haptoglobin synthesis by the liver is markedly increased during the "acute phase response" to systemic inflammation, while IgM is the major product resulting from activation of resting CD22-positive B cells.
Identity-based mutual device authentication schemes for PLC system (2008)

Power line communication (PLC) is a rapidly evolving technology, aiming to use electrical power lines for the transmission of data. With the expansion scale of PLC, the security issues in PLC system have been focused on as one of the challenging problems. Until now in several well-defined technical specifications, security mechanisms which are symmetric key based system have been defined and implemented; these symmetric key based security mechanism are uncomplicated ways to use in a small scale network. This paper presents public/private key distribution and device authentication schemes that adopt IBC (identity-based cryptography) concept in order to use public key based security scheme in large scale PLC system. By eliminating the needs of public key certificates, proposed scheme can reduce the complexity of deploying and managing authentication credentials.
Transactional memory coherence and consistency (2004)

In this paper, we propose a new shared memory model: transactional memory coherence and consistency (TCC). TCC provides a model in which atomic transactions are always the basic unit of parallel work, communication, memory coherence, and memory reference consistency. TCC greatly simplifies parallel software by eliminating the need for synchronization using conventional locks and semaphores, along with their complexities. TCC hardware must combine all writes from each transaction region in a program into a single packet and broadcast this packet to the permanent shared memory state atomically as a large block. This simplifies the coherence hardware because it reduces the need for small, low-latency messages and completely eliminates the need for conventional snoopy cache coherence protocols, as multiple speculatively written versions of a cache line may safely coexist within the system. Meanwhile, automatic, hardware-controlled rollback of speculative transactions resolves any correctness violations that may occur when several processors attempt to read and write the same data simultaneously. The cost of this simplified scheme is higher interprocessor bandwidth. To explore the costs and benefits of TCC, we study the characteristics of an optimal transaction-based memory system, and examine how different design parameters could affect the performance of real systems. Across a spectrum of applications, the TCC model itself did not limit available parallelism. Most applications are easily divided into transactions requiring only small write buffers, on the order of 4-8 KB. The broadcast requirements of TCC are high, but are well within the capabilities of CMPs and small-scale SMPs with high-speed interconnects.
Functional bowel disorders and functional abdominal pain (1999)

The Rome diagnostic criteria for the functional bowel disorders and functional abdominal pain are used widely in research and practice. A committee consensus approach, including criticism from multinational expert reviewers, was used to revise the diagnostic criteria and update diagnosis and treatment recommendations, based on research results. The terminology was clarified and the diagnostic criteria and management recommendations were revised. A functional bowel disorder (FBD) is diagnosed by characteristic symptoms for at least 12 weeks during the preceding 12 months in the absence of a structural or biochemical explanation. The irritable bowel syndrome, functional abdominal bloating, functional constipation, and functional diarrhea are distinguished by symptom-based diagnostic criteria. Unspecified FBD lacks criteria for the other FBDs. Diagnostic testing is individualized, depending on patient age, primary symptom characteristics, and other clinical and laboratory features. Functional abdominal pain (FAP) is defined as either the FAP syndrome, which requires at least six months of pain with poor relation to gut function and loss of daily activities, or unspecified FAP, which lacks criteria for the FAP syndrome. An organic cause for the pain must be excluded, but aspects of the patient's pain behavior are of primary importance. Treatment of the FBDs relies upon confident diagnosis, explanation, and reassurance. Diet alteration, drug treatment, and psychotherapy may be beneficial, depending on the symptoms and psychological features.
Orthogonal Pd- and Cu-Based Catalyst Systems for C- and N-Arylation of Oxindoles (2008)

In the cross-coupling reactions of unprotected oxindoles with aryl halides, Pd- and Cu-based catalyst systems displayed orthogonal chemoselectivity. A Pd-dialkylbiarylphosphine-based catalyst system chemoselectively arylated oxindole at the 3 position, while arylation occurred exclusively at the nitrogen using a Cu-diamine-based catalyst system. Computational examination of the relevant L1Pd(Ar)(oxindolate) and diamine-Cu(oxindolate) species was performed to gain mechanistic insight into the controlling features of the observed chemoselectivity.
Prospects for cannabinoids as anti‐inflammatory agents (2002)

The marijuana plant (Cannabis sativa) and preparations derived from it have been used for medicinal purposes for thousands of years. It is likely that the therapeutic benefits of smoked marijuana are due to some combination of its more than 60 cannabinoids and 200-250 non-cannabinoid constituents. Several marijuana constituents, the carboxylic acid metabolites of tetrahydrocannabinol, and synthetic analogs are free of cannabimimetic central nervous system activity, do not produce behavioral changes in humans, and are effective antiinflammatory and analgesic agents. One cannabinoid acid in particular, ajulemic acid, has been studied extensively in in vitro systems and animal models of inflammation and immune responses. This commentary reviews a portion of the work done by investigators interested in separating the medicinal properties of marijuana from its psychoactive effects. Understanding the mechanisms of the therapeutic effects of nonpsychoactive cannabinoids should lead to development of safe effective treatment for several diseases, and may render moot the debate about "medical marijuana".
