Published: February 2022

Aim Identifying high-risk groups in patient with coronary artery disease (CAD) is critical for predicting future adverse events. fQRS has been shown to be related to major cardiovascular adverse events (MACE) in patients with CAD. However, predictive value of fQRS for more than 5 yrs has not been evaluated. This study examined the predictive value of fQRS in patients with CAD and percutaneous coronary intervention during a 10‑yrs period.Material and methods Patients with CAD and percutaneous coronary intervention between March 2007 and May 2009 were included the study. An electrocardiogram was recorded following percutaneous coronary intervention and analyzed for the presence of fQRS. The fQRS pattern was defined as an additional spike inside the QRS complexes of at least two consecutive leads. Patients were followed for 10 yrs. A MACE was all-cause mortality or new-onset decompensated heart failure. Patients were divided into two groups according to presence or absence of MACE, and their clinical variables were compared.Results Of 1261 patients included in the study, MACE developed in 374 (29.6 %). MACE (+) patients were older (p<0.001), more likely to have diabetes mellitus (p=0.003), fQRS (p<0.001), and ST-elevated myocardial infarction (STEMI) (p<0.001). Multivariable Cox regression analysis revealed that age (p<0.001), STEMI (p=0.001), fQRS (p=0.017), and elevated serum creatinine (p=0.001) were independent predictors of MACE.Conclusion The presence of fQRS predicted MACE during 10 yrs of follow-up of patients with CAD and percutaneous coronary intervention.
Semantic Features of the Verb来 [LÁI]
Authors: Mukhamedjanova Shahbora Kamolovna 
Published: February 2022

Describing the semantics of a verb is a much more difficult task. Because the content of the verb depends in many ways on its distribution. With this in mind, verbs are classified according to the direction of their meaning and the presence or absence of subject-objects with which they interact, and their number, if any. Chinese language researchers classify action verbs as part of a group of action verbs. These verbs can appear in a sentence as an independent verb predicate or as an additional part of speech as a modifier or directional morpheme. These simple verbs represent 来 [lái] to come and 去 [qù] to leave directions of action. They form compound verbs with the same meaning. The verb 来 to come is used when the action is directed to the speaker (or object), and the verb 去 to leave is used if the action is directed away from the speaker (or object). Orientation, in turn, can be set by the object or subject: when the orientation is indicated in the sentence - the object, if not specified - by the subject. Verb 来 [lái] is included in the group of basic simple action verbs in Chinese. The peculiarity of the semantics of the verb 来 [lái] to come is that it determines not only the orientation or direction of the action but also the point of the message, who (or what) describes the situation. The article examines the semantic features of the verbs of 来 [lái] directions of action. Based on the materials in Liu Shushiang’s book “现 代 汉 语 八 百 词. 吕 叔 湘” (800 words in modern Chinese), the models of 来 [lái] verbs as independent and auxiliary verbs are analyzed.

Abstract
Although great progress has been made in nanozymes, their large-scale application still remains a huge challenge due to their unsatisfactory catalytic performances. Featuring unique electronic structure and coordination environment, single atoms nanozymes provide great opportunities to vividly mimic the specific metal catalytic center of natural enzymes and achieve the superior enzyme-like activity. Herein, spin-state engineering of single-atom nanozymes was employed for the first time to enhance peroxidase (POD)-like activity. Pd nanoclusters (PdNC) were introduced to rearrange spin electron occupation of Fe single atom (FeNC-PdNC), in which the electron-withdrawing properties of PdNC make the spin transiting of Fe single atoms from low spin to medium spin, facilitating the heterolysis process of H2O2 and the desorption of H2O. As a result, the spin-rearranged FeNC-PdNC displays superior H2O2 activating performance and kinetics to FeNC. Finally, FeNC-PdNC was applied to the immunosorbent assay for the colorimetric detection of prostate-specific antigen, achieving an ultralow detection limit of 0.38 pg/mL. Our findings provide a new paradigm for designing advanced enzyme mimics and allow to gain a deep insight into the catalytic mechanism of nanozymes.

Abstract
Profound dysfunctional reorganization of spinal networks and extensive loss of functional continuity after spinal cord injury (SCI) has not precluded individuals from achieving coordinated voluntary activity and gaining multi-systemic autonomic control. Bladder function is enhanced by approaches, such as spinal cord epidural stimulation (scES) that modulates and strengthens spared circuitry, even in cases of clinically complete SCI. It is unknown whether scES parameters specifically configured for modulating the activity of the lower urinary tract (LUT) could improve both bladder storage and emptying. Functional bladder mapping studies, conducted during filling cystometry, identified specific scES parameters that improved bladder compliance, while maintaining stable blood pressure, and enabled the initiation of voiding in seven individuals with motor complete SCI. Using high-resolution magnetic resonance imaging and finite element modeling, specific neuroanatomical structures responsible for modulating bladder function were identified and plotted as heat maps. Data from this pilot clinical trial indicate that scES neuromodulation that targets bladder compliance reduces incidences of urinary incontinence and provides a means for mitigating autonomic dysreflexia associated with bladder distention. The ability to initiate voiding with targeted scES is a key step towards regaining volitional control of LUT function, advancing the application and adaptability of scES for autonomic function.

Abstract
COVID-19 has had a substantial impact globally. It spreads readily, particularly in enclosed and crowded spaces, such as public transport carriages, yet there are limited studies on how this risk can be reduced. We developed a tool for exploring the potential impacts of mitigation strategies on public transport networks, called the Systems Analytics for Epidemiology in Transport (SAFE Transport). SAFE Transport combines an agent-based transit assignment model, a community-wide transmission model, and a transit disease spread model to support strategic and operational decision making. For this simulated COVID-19 case study, the transit disease spread model incorporates both direct (person-to-person) and fomite (person-to-surface-to-person) (person-surface-person) transmission modes. We determine the probable impact of wearing face masks on trains over a seven day simulation horizon, showing substantial and statistically significant reductions in new cases when passenger mask wearing proportions are greater than 80%.

Abstract
Osteoporosis is a systemic skeletal disease affecting postmenopausal women worldwide. Adverse side effects are associated with long term conventional hormone therapy in osteoporosis treatment. Estradiol was loaded in PLGA nanoparticles coated with polyethylene imine to impart positive surface charge to preferentially localize hormone in the negative surface of bone environment evading unwanted side effects. Nanoparticles prepared by emulsion solvent evaporation method were smaller than 200 nm with a surface charge of 35mV. In vitro hydroxyapatite binding studies revealed superior binding of 82% by polycationic particles compared to meagre 28% by plain PLGA nanoparticles. In vivo biodistribution studies in mice displayed nearly 3 fold higher bone uptake by cationic nanoparticles compared to plain PLGA system at 24 hours. Hematological and histological evaluation in acute toxicity study showed safe and nontoxic nature of cationic nanoparticles.. Higher C max, AUC 0-inf, t1/2 values and lower clearance values was observed with nanoparticles compared to estradiol solution which can potentially lower frequency of administration compared to plain drug solutions. The osteoprotective effect of estradiol in cationic nanoparticles was established in ovariectomised rats. The osteotropic, nontoxic cationic nanoparticles can be considered a prototype for delivery of plethora of antiresoptive/anabolic agents to the skeletal environment.

Abstract
The vagus nerve constitutes a key link between the vegetative and the central nervous system. However, the impact of vagal activity on cognitive processes is largely unknown. Recent studies in animals and humans show that vagus nerve stimulation is associated with enhanced reward-seeking and dopamine-release in the brain. Social interaction recruits similar brain circuits to reward processing. We hypothesize that vagus nerve stimulation (VNS) boosts rewarding aspects of social behavior and compare the impact of transcutaneous VNS (tVNS) and sham stimulation on social interaction in 19 epilepsy patients in a double-blind pseudo-randomized study. Using a well-established paradigm, i.e., the prisoner’s dilemma, we investigate effects of stimulation on cooperative behavior, as well as interactions of stimulation effects with patient characteristics. A repeated-measures ANOVA and a linear mixed-effects model provide converging evidence that tVNS boosts cooperation. Partial correlations reveal that this effect varies as a function of neuroticism, a personality trait linked to the dopaminergic system. Behavioral modeling indicates that tVNS induces a behavioral starting bias towards cooperation, which is independent of the decision process. This study provides evidence for the causal influence of vagus nerve activity on social interaction and may have clinical implications for disorders affecting social behavior.
Soil vulnerability to acid or alkali spills: Identifying changes in physicochemical properties and pH buffering capacity in response to spills

Published: February 2022

Abstract
Acid or alkali spills destroy physicochemical properties of soils and result in irreversible damages on soil ecological functions. This study examined changes in physicochemical properties (i.e., organic matter and clay content, and cation exchange capacity (CEC)) and pH buffering capacity (indicator of soil function) of twenty field soils as a result of acid or alkali spills, and identified characteristics of soils vulnerable to the spills. While both acid and alkali spills did not significantly change clay content, organic matter decreased about 40% and 60%, respectively, consequently resulting in 41% of decrease in pH buffering capacity. Unlike untreated soils whose pH buffering capacity was strongly predicted (R2=0.79) by organic matter and clay content, the value of acid- and alkali-spilled soils was well predicted by the clay content alone (R2=0.61 and 0.80, respectively). In addition, results of clustering analysis demonstrated that soils whose pH buffering capacity are higher than 50 mmol kg-1 pH unit-1 are the most vulnerable to the spills due to high organic matter content. Our findings indicate that soil vulnerability to the spills can be evaluated from soil properties, and it can be potentially used to classify vulnerable soils in the areas with a high occurrence of spills.
