Properties of Somatosensory Synaptic Integration in Cerebellar Granule Cells In Vivo

In decerebrated, nonanesthetized cats, we made intracellular whole-cell recordings and extracellular cell-attached recordings from granule cells in the cerebellar C3 zone. Spontaneous EPSPs had large, relatively constant peak amplitudes, whereas IPSPs were small and did not appear to contribute substantially to synaptic integration at a short time scale. In many cases, the EPSPs of individual mossy fiber synapses appeared to be separable by their peak amplitudes. A substantial proportion of our granule cells had small receptive fields on the forelimb skin. Skin stimulation evoked explosive responses in which the constituent EPSPs were analyzed. In the rising phase of the response, our analyses indicated a participation of three to four different mossy fiber synapses, corresponding to the total number of mossy fiber afferents. The cutaneous receptive fields of the driven EPSPs overlapped, indicating an absence of convergence of mossy fibers activated from different receptive fields. Also in granule cells activated by joint movements did we find indications that different afferents were driven by the same type of input. Regardless of input type, the temporal patterns of granule cell spike activity, both spontaneous and evoked, appeared to primarily follow the activity in the presynaptic mossy fibers, although much of the nonsynchronized mossy fiber input was filtered out. In contrast to the prevailing theories of granule cell function, our results suggest a function of granule cells as signal-to-noise enhancing threshold elements, rather than as sparse coding pattern discriminators or temporal pattern generators.
Use of the biochip microarray system in detection of myocardial injury caused by radiofrequency catheter ablation

Abstract Background: In a prospective study, we measured plasma markers of myocardial damage induced by radiofrequency catheter ablation (RFA) with the protein biochip microarray system. Methods: A total of 32 consecutive patients undergoing RFA for atrioventricular nodal re-entry tachycardia (AVNRT), right atrial flutter (AFL) and atrial fibrillation (AF) were included in the study. Cardiac troponin I (cTnI), creatine kinase isoenzyme MB (CK-MB), heart-type fatty acid binding protein (hFABP) and glycogen phosphorylase BB (GPBB) were measured using biochip array technology at baseline and 24 h after the procedure. Results: Values for all markers increased 24 h after RFA (cTnI: 0.92±0.49 μg/L vs. 0.33±0.06 μg/L, p<0.001; CK-MB: 3.79±2.04 μg/L vs. 1.85±0.55 μg/L, p<0.001; hFABP: 2.82±0.95 μg/L vs. 2.00±0.95 μg/L, p<0.001; GPBB: 9.07±5.83 μg/L vs. 4.70±2.50 μg/L, p<0.001). The correlations between plasma marker levels and RFA time were cTnI: r=0.63, p<0.01; CK-MB: r=0.75, p<0.01; hFABP: r=0.55, p<0.05, GPBB: r=0.51, p<0.05; the correlation between RFA time and number of RF applications was significant (r=0.81, p<0.001). Patients with RFA due to AF or flutter had elevated cTnI, CK-MB and hFABP levels compared to patients with AVNRT (cTnI: 1.14± 0.49 μg/L vs. 0.59±0.25 μg/L, p<0.05; CK-MB: 4.46± 2.07 μg/L vs. 2.81±1.54 μg/L, p<0.05; hFABP: 3.21± 0.98 μg/L vs. 2.25±0.54 μg/L, p<0.01). Conclusions: Myocardial injury induced by RFA can be detected by cTnI, CK-MB, hFABP and GPBB. Plasma cTnI, CK-MB and hFABP levels significantly increased in patients with AFL and AF compared to patients with AVNRT. The increase of cTnI, CK-MB and GPBB levels correlates with the total duration of RFA. Clin Chem Lab Med 2008;46:1726–8.
Talking robots with Lego MindStorms

This paper shows how talking robots can be built from off-the-shelf components, based on the Lego MindStorms robotics platform. We present four robots that students created as final projects in a seminar we supervised. Because Lego robots are so affordable, we argue that it is now feasible for any dialogue researcher to tackle the interesting challenges at the robot-dialogue interface.
Development of immunotherapeutic strategies for HIV-1

In the majority of untreated patients, HIV-1 infection presents as a progressive disease of the immune system. Recent studies indicate that immune responses can be induced in HIV-1 infected individuals, leading to some immune control of virus replication. Such immune responses are also observed in small numbers of untreated HIV-1 infected long-term non-progressor (LTNP) patients, as well as in other viral infections (including those with human herpesviruses). Emerging novel technologies, animal studies and detailed immunological studies have proven invaluable in defining the immune responses that are associated with a favourable clinical outcome. Central effector and regulatory cells are HIV-1-specific CD8+ cytotoxic T-lymphocytes (CTL) and CD4+ helper T-lymphocytes respectively. Fully functional antigen-presenting cells (APC) are also essential in all stages of HIV-1 infection and possibly some (but not all) antibody responses contribute to beneficial immunity. The availability of combination anti-retroviral drug therapy, which successfully controls viraemia, has enabled a beneficial outcome in many HIV-1 infected individuals. Since no chronically HIV-1 infected patient has been shown to eradicate virus, novel approaches utilising therapeutic immunisation and various cytokines to manipulate immune responses and to induce and steer immunity towards a desired phenotype are required. There is a clear rationale for immunotherapeutic intervention in chronic progressive HIV-1 infection, which forms the foundation for novel approaches aimed at inducing and maintaining immune control. Here we review the immunopathogenesis of HIV-1 infection and discuss the promises of therapeutic immunisation and immunotherapy in general and their potential in the treatment of chronic HIV-1 disease.
Open World Probabilistic Databases (Extended Abstract)

Large-scale probabilistic knowledge bases are becoming increasingly important in academia and industry alike. They are constantly extended with new data, powered by modern information extraction tools that associate probabilities with database tuples. In this paper, we revisit the semantics underlying such systems. In particular, the closed-world assumption of probabilistic databases, that facts not in the database have probability zero, clearly conflicts with their everyday use. To address this discrepancy, we propose an open-world probabilistic database semantics, which relaxes the probabilities of open facts to intervals. While still assuming a finite domain, this semantics can provide meaningful answers when some probabilities are not precisely known. For this open-world setting, we propose an efficient evaluation algorithm for unions of conjunctive queries. Our open-world algorithm incurs no overhead compared to closed-world reasoning and runs in time linear in the size of the database for tractable queries. All other queries are #P-hard, implying a data complexity dichotomy between linear time and #P. For queries involving negation, however, open-world reasoning can become NP-, or even NPPP-hard. Finally, we discuss additional knowledge-representation layers that can further strengthen open-world reasoning about big uncertain data.
Progress in pathogenesis and treatment of type A hepatic encephalopathy in acute liver failure: a comprehensive review

Hepatic encephalopathy is a serious neuropsychiatric complication caused by liver failure, which is characterized by the development of cognitive and motor disorders into coma. Typically, hepatic encephalopathy can be divided into three types (A, B, and C) according to the etiology. Type A hepatic encephalopathy (AHE) caused by acute liver failure seriously affects the prognosis of patients, ranging from mild neuropsychological changes to coma, brain edema, and even death. So far, the research on the pathogenesis of AHE has focused on the toxic effects of ammonia on the central nervous system, metabolic disorders (glutamine and lactate accumulation), neurotransmission alteration, systemic inflammation, especially neuro-inflammation. All these mechanisms are not independent, but mutually have synergistic effects. In clinic, treatment of AHE based on only one mechanism is often ineffective. To clarify the pathogenesis and the interaction among the mechanisms will be beneficial to the effective treatment of AHE and reduce the mortality. The aim of this review is to provide comprehensive scientific evidence for the clinical treatment of AHE via collecting and analyzing the latest mechanism of AHE, and clarifying the relationship among these mechanisms combing the investigation of the latest research progress of drug treatment of acute liver failure. Consequently, we find that the pathogenesis of AHE is a complex neurocognitive disorder shaped by interactions among hyperammonemia, inflammation, and changes in neurotransmission, the signaling pathways thereby integrating the inflammatory and neurological inputs to impact pathophysiological or neurobehavioral outcomes.
The Influence of Additional Treatments on the Survival of Patients Undergoing Transarterial Radioembolization (TARE)

The aim of this study was to present our preliminary experience with transarterial radioembolization (TARE) using Yttrium-90 (90Y), compare the cancer-specific survival (CSS) of patients with hepatocellular carcinoma (HCC) and colorectal cancer (CRC) liver metastases undergoing TARE, and investigate the influence of additional treatments on CSS. Our database was interrogated to retrieve patients who had undergone TARE using Yttrium-90 (90Y) glass or resin microspheres. Kaplan–Meier curves and the log-rank test were employed to conduct survival analysis for the different groups (p < 0.05). Thirty-nine patients were retrieved (sex: 27 M, 12 F; mean age: 63.59 ± 15.66 years): twenty-three with hepatocellular carcinoma (HCC) and sixteen with CRC liver metastasis. Globally, the patients with HCC demonstrated a significantly longer CSS than those with CRC liver metastasis (22.64 ± 2.7 vs. 7.21 ± 1.65 months; p = 0.014). Among the patients with CRC liver metastasis, those receiving TARE and additional concomitant treatments (n = 10) demonstrated a longer CSS than the CRC patients receiving only TARE (9.97 ± 2.21 vs. 2.59 ± 0.24 months; p = 0.06). In the HCC group, there was a trend of a longer CSS in patients (n = 8) receiving TARE and additional treatments (27.89 ± 3.1 vs. 17.69 ± 3.14 months; p = 0.15). Patients with HCC seem to achieve a longer survival after TARE compared to patients with CRC liver metastases. In patients with CRC liver metastases, the combination of TARE and additional concomitant treatments may improve survival.
The architecture of interdependent minds: A Motivation-management theory of mutual responsiveness.

A model of mutual responsiveness in adult romantic relationships is proposed. Behaving responsively in conflict-of-interest situations requires one partner to resist the temptation to be selfish and the other partner to resist the temptation to protect against exploitation. Managing risk and the attendant temptations of self-interest require the interpersonal mind to function in ways that coordinate trust and commitment across partners. The authors describe a system of procedural or "if. then" rules that foster mutuality in responsiveness by informing and motivating trust and commitment. The authors further argue that tuning rule accessibility and enactment to match the situations encountered in a specific relationship shapes its personality. By imposing a procedural structure on the interdependent mind, the proposed model of mutual responsiveness reframes interdependence theory and generates important research questions for the future.
The Possible Role of Pathogens and Chronic Immune Stimulation in the Development of Diffuse Large B-Cell Lymphoma

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma. The disease is very heterogeneous, with distinct genetic alterations in subtypes. The WHO 2022 5th edition classification identifies several minor groups of large B-cell lymphoma where the pathogenetic role of viruses (like EBV and HHV-8) is identified. Still, most cases fall into the group of DLBCL not otherwise specified (NOS). No review focuses only on this specific lymphoma type in the literature. The pathogenesis of this entity is still not fully understood, but several viruses and bacteria may have a role in the development of the disease. The authors review critical pathogenetic events in the development of DLBCL (NOS) and summarize the data available on several pathogenetic viruses and bacteria that have a proven or may have a potential role in the development of this lymphoma type. The possible role of B-cell receptor signaling in the microenvironment is also discussed. The causative role of the Epstein–Barr virus (EBV), human herpesvirus-8 (HHV-8), Hepatitis C virus (HCV), human immunodeficiency virus (HIV), Hepatitis B virus (HBV), and other viruses are explored. Bacterial infections, such as Helicobacter pylori, Campylobacter jejuni, Chlamydia psittaci, Borrelia burgdorferi, and other bacteria, are also reviewed.
Efficacy and specificity of computer-assisted cognitive remediation in schizophrenia: a meta-analytical study

Background Cognitive remediation is frequently based on computerized training methods that target different cognitive deficits. The aim of this article was to assess the efficacy of computer-assisted cognitive remediation (CACR) in schizophrenia and to determine whether CACR enables selective treatment of specific cognitive domains. Method A meta-analysis was performed on 16 randomized controlled trials evaluating CACR. The effect sizes of differences between CACR and control groups were computed and classified according to the cognitive domain assessed. The possible influences of four potential moderator variables were examined: participants' age, treatment duration, weekly frequency, and control condition type. To test the domain-specific effect, the intended goal of each study was determined and the effect sizes were sorted accordingly. The effect sizes of the cognitive domains explicitly targeted by the interventions were then compared with those that were not. Results CACR enhanced general cognition with a mean effect size of 0.38 [confidence interval (CI) 0.20–0.55]. A significant medium effect size of 0.64 (CI 0.29–0.99) was found for Social Cognition. Improvements were also significant in Verbal Memory, Working Memory, Attention/Vigilance and Speed of Processing with small effect sizes. Cognitive domains that were specifically targeted by the interventions did not yield higher effects than those that were not. Conclusions The results lend support to the efficacy of CACR with particular emphasis on Social Cognition. The difficulty in targeting specific domains suggests a ‘non-specific’ effect of CACR. These results are discussed in the light of the possible bias in remediation tasks due to computer interface design paradigms.
Impact of treatment with acetylsalicylic acid on the proaggregatory effects of adrenaline in vitro in patients with stable angina pectoris: influence of the anticoagulant.

1. The impact of oral acetylsalicylic acid treatment on the enhancing effect of adrenaline on platelet aggregation in vitro was investigated in patients with stable angina pectoris. In addition, the influence of different anticoagulants (i.e. hirudin and citrate) on platelet aggregation in vitro was compared. 2. Eighty-four patients with stable angina pectoris were studied. Sixteen patients were on acetylsalicylic acid treatment (150-250 mg daily), whereas 68 patients were free from acetylsalicylic acid. Platelet-rich-plasma was prepared from citrate- or hirudin-anticoagulated blood. The EC50 (i.e. the concentration of agonist required to produce half-maximal aggregation) for the ADP-induced extent of aggregation was determined. Thereafter the enhancing effect of adrenaline (10 and 50 nmol/l) on ADP-induced aggregation (at EC50) was investigated. 3. In the patients with angina, acetylsalicylic acid caused the expected effects on ADP-induced platelet responses. Adrenaline significantly enhanced both the extent of aggregation and the initial rate of aggregation (primary aggregation), irrespective of the anticoagulant used. In acetylsalicylic acid-treated patients (citrated platelet-rich plasma) the extent of aggregation was partly inhibited, but no significant effect on the rate of aggregation could be observed. 4. A comparative substudy of the anticoagulants in healthy subjects (n = 8) showed that both the aggregating effect of ADP per se and the enhancing effect of adrenaline on ADP-induced aggregation (at EC50) were less influenced by acetylsalicylic acid when evaluated in hirudinized platelet-rich plasma (i.e. with physiological levels of extracellular calcium) as compared with citrated platelet-rich plasma.

Is neck circumference measurement an indicator for abdominal obesity? A pilot study on Turkish Adults.

BACKGROUND Neck circumference (NC) measurement is one of the simple screening measurements which can be used as an index of upper body fat distribution to identify obesity. OBJECTIVES The aim of this study was to determine the relationship between neck circumferences and obesity. METHODS A total 411 volunteer adults participated in this study (174 men, 237 women). A questionnaire which consisted of anthropometric measurements and demographic features was used. Patients with NC ≥37 cm for men and ≥34 cm for women require evaluation of overweight status. RESULTS The percentages of the men and women with BMI ≥ 25 kg/m(2) were 55.2% and 27.0% respectively and with high neck circumferences were 85.1% and 38.8%, respectively. The percentages of the men and women with high waist circumference were 31.6% and 79.3%, respectively. In both gender there were positive significant correlations between neck circumference, body weight (men, r=0.576; women, r=0.702; p=0.000), waist circumferences (men, r=0.593; women r=0.667; p=0.000), hip circumferences (men, r=0.568; women, r=0.617; p=0.000) and BMI (men, r=0.587; women, r=0.688; p=0.000). CONCLUSIONS This study indicates that NC was associated with body weight, BMI, waist and hip circumferences and waist/hip ratio for men and women. A significant association was found between NC and conventional overweight and obesity indexes. NC was associated with waist/hip ratio for men and women.
Distribution and Preservation of Root‐ and Shoot‐Derived Carbon Components in Soils Across the Chinese‐Mongolian Grasslands

The relative contribution of roots versus shoots to soil organic carbon (SOC) is a long‐debated topic related to soil carbon formation and dynamics. However, the variation of root‐ and shoot‐derived carbon in natural soils remains poorly constrained due to limited tools to separate them. Here we overcome the difficulty by analyzing biomarkers for root (suberin) and shoot (cutin) in grassland soils spanning >7,000 km on the Qinghai‐Tibetan and Mongolian Plateaus. Coupled with a comprehensive list of climatic, edaphic, and vegetation variables, we assess their inputs, distribution, and preservation patterns. We find that while suberin was a root‐specific tracer, cutin biomarkers that occurred only in trace amount in roots also had a minor but nonnegligible contribution from belowground sources due to the massive root mass in the alpine grasslands. Both components had higher SOC‐normalized concentrations in the alpine than temperate grasslands, along with a higher preservation percentage against net primary productivity and a lower degradation parameter, suggesting a better preservation of these plant‐derived lipid components in the alpine region. Moreover, while cutin and suberin abundances were affected by plant inputs and other SOC constituents, the root mass normalized incorporation efficiency of suberin was only positively correlated to SOC in both regions with a steeper slope in the alpine grasslands and also negatively correlated to root mass in the alpine soils. These results imply that root carbon incorporation is sensitive to environmental variations in the cold region, suggesting potentially more dynamic alterations to root carbon sequestration with environmental changes.
THE STABILITY OF THE SYMBIOSIS BETWEEN DIOECIOUS FIGS AND THEIR POLLINATORS: A STUDY OF FICUS CARICA L. AND BLASTOPHAGA PSENES L.

Each Ficus species depends on a specific mutualistic wasp for pollination. The wasp breeds on the fig, each larva destroying a female flower. It is, however, not known why the wasps have not evolved the ability to use all female flowers. In “dioecious” figs, the wasp can only breed in the female flowers of the “male” trees, so that pollination of a female tree is always lethal. The wasps should therefore be selected to avoid female trees. Field data is presented showing that the fruiting phenology of the dioecious fig Ficus carica is such that this selection does not occur: syconia are not receptive at the same time on “male” and female trees. Most wasps are forced to emerge from the syconia of “male” trees at a time when they will not be able to reproduce, whether they avoid female trees or not. This aspect of the life cycle of the wasp, although noticed, has been obscured in most previous studies. It is shown that the fruiting phenology of Ficus carica, which stabilizes the symbiosis, is the result of short‐term selective pressures on the male function of the trees. Such selective pressures suggest a possible pathway from monoecy to dioecy in Ficus under seasonal climates.
Cryptorchidism and testicular germ cell tumors: comprehensive meta-analysis reveals that association between these conditions diminished over time and is modified by clinical characteristics

Introduction: Risk of testicular germ cell tumors (TGCT) is consistently associated with a history of cryptorchidism (CO) in epidemiologic studies. Factors modifying the association may provide insights regarding etiology of TGCT and suggest a basis for individualized care of CO. To identify modifiers of the CO-TGCT association, we conducted a comprehensive, quantitative evaluation of epidemiologic data. Materials and Methods: Human studies cited in PubMed or ISI Web of Science indices through December 2011 and selected unpublished epidemiologic data were reviewed to identify 35 articles and one unpublished dataset with high-quality data on the CO-TGCT association. Association data were extracted as point and 95% confidence interval estimates of odds ratio (OR) or standardized incidence ratio (SIR), or as tabulated data. Values were recorded for each study population, and for subgroups defined by features of study design, CO and TGCT. Extracted data were used to estimate summary risk ratios (sRR) and evaluate heterogeneity of the CO-TGCT association between subgroups. Results: The overall meta-analysis showed that history of CO is associated with four-fold increased TGCT risk [RR = 4.1(95% CI = 3.6–4.7)]. Subgroup analyses identified five determinants of stronger association: bilateral CO, unilateral CO ipsilateral to TGCT, delayed CO treatment, TGCT diagnosed before 1970, and seminoma histology. Conclusions: Modifying factors may provide insight into TGCT etiology and suggest improved approaches to managing CO. Based on available data, CO patients and their parents or caregivers should be made aware of elevated TGCT risk following orchidopexy, regardless of age at repair, unilateral vs. bilateral non-descent, or position of undescended testes.
