ObjectivesThis study aimed to systematically review the efficacy of transcranial magnetic stimulation treatment in reducing suicidal ideation in depression.MethodsPubMed, Web of Science, CBMdisc, WanFang, Chongqing VIP, and CNKI databases were electronically searched for randomized controlled trials of transcranial magnetic stimulation (TMS) intervention in the management of suicidal ideation from inception to February 24, 2021. Two reviewers independently screened studies, extracted data, and assessed the quality of included studies. Meta-analysis was then performed using STATA 15.1 software.ResultsA total of eight articles involving 566 patients were included. The meta-analysis results showed that the suicidal ideation scores of the group who received TMS treatment were significantly lower [standardized mean difference (SMD) = −0.415, 95% confidence interval (CI): −0.741 to −0.090, P = 0.012] than those of the control group. Subgroup analysis showed that age, TMS pattern, frequency of intervention, and stimulation threshold altered the TMS efficacy.ConclusionsEvidence showed that TMS achieved superior results in reducing suicidal ideation. Because of the limited quality and quantity of the included studies, more high-quality studies are required to verify the conclusions.Systematic Review Registrationhttps://inplasy.com/, identifier: INPLASY202180065.

BackgroundMethamphetamine and ketamine are commonly used club drugs. Both of them have been reported to mimic psychotic symptoms of schizophrenia. However, the prevalence and detailed features of psychotic symptoms among methamphetamine use disorder (MUD) and ketamine use disorder (KUD) patients are largely unknown. This study aimed to measure psychotic symptoms among patients with MUD and KUD.MethodsA total sample of 842 patients from voluntary drug rehabilitation centers, including 462 MUD patients and 380 KUD patients, were invited to this study. The Positive and Negative Syndrome Scale (PANSS) was applied to assess psychotic symptoms in these two groups of patients.ResultsThe prevalence of psychotic symptoms was significantly higher among MUD patients than KUD patients (75.1 vs. 50.5%, 95% CI: 3.532 – 11.858, p &lt; 0.001). Compared with KUD patients, MUD patients were more likely to experience positive symptoms (PANSS positive scores: 11.5 ± 6.07 vs. 15.1 ± 8.22, P &lt; 0.001) and negative symptoms (PANSS negative scores: 12.4 ± 6.60 vs. 14.5 ± 8.63, P &lt; 0.001), but not general symptoms (PANSS general scores: 31.2 ± 13.90 vs. 32.2 ± 15.13, P &lt; 0.001).ConclusionsThe current study found that more than half of MUD and KUD patients experienced psychotic symptoms, and that patients with MUD are more likely to experience positive and negative symptoms than patients with KUD. The findings provide a new perspective for exploring the neuropathological mechanism of psychotic symptoms of schizophrenia.

BackgroundThe COVID-19 has spread across the globe in a short time and affected people's life, especially patients with severe mental disorders. Poor adherence to antipsychotics was usually associated with an increasing risk of relapse. This study investigated medication adherence status among patients with severe mental disorders in low-income families during COVID-19 outbreak and the influencing factors.MethodsTo select patients with severe mental disorders in low-income families in central China's Henan Province, we used multi-stage stratified random sampling method. Trained interviewers and psychiatrists collected questionnaire responses from the patients through face-to-face interviews or video interviews. Logistic regression models were used to examine factors that influence the status of medication adherence.ResultsA total of 24,763 valid questionnaires were collected between March 10, 2020, and March 31, 2020. The regular medication rate of patients with severe mental disorders in low-income families during the COVID-19 outbreak was 51.46%. Twelve factors were found to influence medication adherence of investigated individuals. Positive factors for regular medication were younger age, higher education level of patients and their guardians, higher medical expenditure, higher level of self-care ability, having subsidies for care and supervision, having disability certificate and personal care, etc.ConclusionsThe COVID-19 outbreak affected the medication adherence among patients with severe mental disorders in low-income families. The influencing factors are complicated and diverse, including psychological effects, traffic impact, and economy, etc. The government should pay more efforts on social assistance programs and flexibly deal with difficulties during public health emergencies like the COVID-19.

BackgroundTo date, there is a lack of sufficient evidence on the type of clusters in which severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is most likely to spread. Notably, the differences between cluster-level and population-level outbreaks in epidemiological characteristics and transmissibility remain unclear. Identifying the characteristics of these two levels, including epidemiology and transmission dynamics, allows us to develop better surveillance and control strategies following the current removal of suppression measures in China.MethodsWe described the epidemiological characteristics of SARS-CoV-2 and calculated its transmissibility by taking a Chinese city as an example. We used descriptive analysis to characterize epidemiological features for coronavirus disease 2019 (COVID-19) incidence database from 1 Jan 2020 to 2 March 2020 in Chaoyang District, Beijing City, China. The susceptible-exposed-infected-asymptomatic-recovered (SEIAR) model was fitted with the dataset, and the effective reproduction number (Reff) was calculated as the transmissibility of a single population. Also, the basic reproduction number (R0) was calculated by definition for three clusters, such as household, factory and community, as the transmissibility of subgroups.ResultsThe epidemic curve in Chaoyang District was divided into three stages. We included nine clusters (subgroups), which comprised of seven household-level and one factory-level and one community-level cluster, with sizes ranging from 2 to 17 cases. For the nine clusters, the median incubation period was 17.0 days [Interquartile range (IQR): 8.4–24.0 days (d)], and the average interval between date of onset (report date) and diagnosis date was 1.9 d (IQR: 1.7 to 6.4 d). At the population level, the transmissibility of the virus was high in the early stage of the epidemic (Reff = 4.81). The transmissibility was higher in factory-level clusters (R0 = 16) than in community-level clusters (R0 = 3), and household-level clusters (R0 = 1).ConclusionsIn Chaoyang District, the epidemiological features of SARS-CoV-2 showed multi-stage pattern. Many clusters were reported to occur indoors, mostly from households and factories, and few from the community. The risk of transmission varies by setting, with indoor settings being more severe than outdoor settings. Reported household clusters were the predominant type, but the population size of the different types of clusters limited transmission. The transmissibility of SARS-CoV-2 was different between a single population and its subgroups, with cluster-level transmissibility higher than population-level transmissibility.

Objectives: The present study, one of the first to look at COVID-19 and coping in Iran, aimed at mapping, describing and understanding the coping methods academics employ as protective resources to deal with the psychological challenges and social isolation during the COVID-19 pandemic. We specifically aimed at identifying the meaning-making coping methods used and understanding the influence of culture. The guiding research question has been: Are there differences in meaning-making coping methods by gender, age group, work/student status, and place of residence?Design: The study, which used convenience sampling, was a quantitative inquiry. It employed a modified version of the RCOPE scale among faculty/staff members and students in Iran (n = 196, 75% women).Results: The most frequently used coping method among all subgroups of the study sample was thinking that life is part of a greater whole, followed by praying to Allah/God. The least used coping methods were the negative religious ones. Gender differences were found for being alone and contemplating, stronger for men. Thinking that life is part of a greater whole was found mainly among on-campus students. Praying to Allah/God was most common among the youngest staff and students, as well as among women. Two segments of respondents were discovered—the Theists and Non-theists—where the former used more religious coping methods, were more likely to be women, older staff and students, on-campus students, married, have children, and lived in capital.Conclusions: Our conclusion is that the RCOPE methods, which include religious and spiritual meaning-making methods, are of great importance to the studied Iranian informants. However, they use some secular existential meaning-making coping strategies too. This is explained by the role of religion in the larger orientation system and frame of reference in parallel with a secular worldview. Further, a sharp distinction between religious and secular worldviews was not found, which is explained by the fact that secular norms are hardly internalized in ways of thinking in Iran.

A2A adenosine receptors (A2A-AR) have a cardio-protective function upon ischemia and reperfusion, but on the other hand, their stimulation could lead to arrhythmias. Our aim was to investigate the potential use of the PET radiotracer [18F]FLUDA to non-invasively determine the A2A-AR availability for diagnosis of the A2AR status. Therefore, we compared mice with cardiomyocyte-specific overexpression of the human A2A-AR (A2A-AR TG) with the respective wild type (WT). We determined: (1) the functional impact of the selective A2AR ligand FLUDA on the contractile function of atrial mouse samples, (2) the binding parameters (Bmax and KD) of [18F]FLUDA on mouse and human atrial tissue samples by autoradiographic studies, and (3) investigated the in vivo uptake of the radiotracer by dynamic PET imaging in A2A-AR TG and WT. After A2A-AR stimulation by the A2A-AR agonist CGS 21680 in isolated atrial preparations, antagonistic effects of FLUDA were found in A2A-AR-TG animals but not in WT. Radiolabelled [18F]FLUDA exhibited a KD of 5.9 ± 1.6 nM and a Bmax of 455 ± 78 fmol/mg protein in cardiac samples of A2A-AR TG, whereas in WT, as well as in human atrial preparations, only low specific binding was found. Dynamic PET studies revealed a significantly higher initial uptake of [18F]FLUDA into the myocardium of A2A-AR TG compared to WT. The hA2A-AR-specific binding of [18F]FLUDA in vivo was verified by pre-administration of the highly affine A2AAR-specific antagonist istradefylline. Conclusion: [18F]FLUDA is a promising PET probe for the non-invasive assessment of the A2A-AR as a marker for pathologies linked to an increased A2A-AR density in the heart, as shown in patients with heart failure.

Streptomyces sp. GET02.ST and Achromobacter sp. GET02.AC were isolated together from the gut of the wharf roach, Ligia exotica, inhabiting the intertidal zone of the west coast of Korea. The co-cultivation of these two strains significantly induced the production of two new metabolites, ligiamycins A (1) and B (2), which were barely detected in the single culture of Streptomyces sp. GET02.ST. The planar structures of ligiamycins A (1) and B (2) were elucidated as new decalins coupled with amino-maleimides by the analysis of various spectroscopic data, including nuclear magnetic resonance (NMR), ultraviolet (UV), and mass (MS) data. The assignment of two nitrogen atoms in amino-maleimide in 1 was accomplished based on 1H-15N heteroatom single quantum coherence spectroscopy (HSQC) NMR experiments. The relative configurations of the ligiamycins were determined using rotating frame Overhauser effect spectroscopy (ROESY) NMR data, and their absolute configurations were deduced by comparing their experimental and calculated optical rotations. Ligiamycin A (1) displayed antibacterial effects against Staphylococcus aureus and Salmonella enterica, while ligiamycin B (2) exhibited mild cell cytotoxicity against human colorectal cancer cells.

Authors: Romanovskiy S. 
Published: January 2022

The article presents the results of studies proving the effectiveness of the use of heat- insulation plates containing noil of flax as a structure-forming material.
Information on field tests in the construction of a wall enclosure with a ventilated insulation sys-tem of an operated one-story residential building and studies of the operational and technological characteristics of heat-insulating materials made of flax fiber is presented. On the basis of experi-mental data, the values of the heat transfer resistance of the wall enclosure are calculated at an air temperature of -2 ° C to -19 °C. The dependences of the distribution of moisture over the thickness of the heat-insulating layer are constructed. The test results shows that during the operation of an exter-nal wall fence with a ventilated insulation system, the moisture content of the heat-insulating material based on noils of flax is 15.5 %. The outside air temperature of -19 °C it has a heat transfer resistance similar to that of the Acoterm Flax heat-insulating plate, equal to 3,04 (m2∙°C)/W. The study of techno-logical characteristics shows that flax noils insulation can be cut, sawn and mounted to a wall fence using dowel-nails. The fire resistance tests carried out shows that the heat-insulating plates based on flax fibers do not ignite under the influence of fire, but the fibers of the noils are pulled out. The mate-rial belongs to the G4 combustible group and has a low smoke-generating ability.
As a result of the research, the rational use of lflax noils for the production of heat-insulating boards has been substantiated.

Earthquakes are the biggest threat of natural disasters in Indonesia because they occur suddenly and attack densely populated areas, such as large cities. Earthquakes with a magnitude of about 5 or 6 on the Richter scale occur in almost all regions in Indonesia. If the force of the earthquake passes 7 on the Richter scale, it can cause a lot of damage. After the earthquake caused many fatalities, material losses, and others arising from this disaster. During this time after an earthquake natural disaster, residents have difficulty informing victims and damage to homes because by using a system that is still manual. Website design using waterfall method, the website will make it easier for the public to report information related to the number of victims of each family member, damage to the house and disbursement of funds if the data has been approved by the officer. The results of the study, namely getting information related to damage due to earthquake disasters from the side of residents / victims.

Analysis of band structures of phosphorene and bismuthene based on the double group theory
Authors: Widianto Muhammad Yusuf Hakim , Saito Mineo 
Published: January 2022

Abstract
We study band structures of group-V two-dimensional materials, i.e. phosphorene and bismuthene, by carrying out first-principles calculations including spin–orbit coupling (SOC). We propose a method to identify irreducible representations (IR) of both symmorphic and nonsymmorphic systems. We find for the α structures that all the non-SOC bands are doubly degenerated on the first Brillouin zone edge due to sticking or pairing of bands and that the SOC slightly splits the bands in most of the cases. We evaluate Z
2 invariants based on identified IR. We find that the Z
2 invariant of 1 in the case of β bismuthene is due to the strong SOC that reverses the highest occupied and the lowest unoccupied bands at the Γ point.
Measurement of mechanical properties of liquid by observing droplet oscillation on substrates

Published: January 2022

Abstract
In this paper, we introduce a method to measure the surface tension of a droplet on a solid substrate by observing the resonance oscillation excited by applying Maxwell stress using electric field tweezers in a noncontact manner. Additionally, we measured the frequency spectrum of the oscillation amplitude using a stroboscopic imaging technique. The resonance frequency of the droplet was inversely proportional to the 3/2th power of the droplet radius, with a contact angle of approximately π/2 rad. The acquired result is in good agreement with the theory derived by extending the established formula for a free-sphere droplet. Furthermore, the contact angle dependence of the resonance frequency can be qualitatively explained based on the behavior of waves on a confined liquid surface.
