Abstract
Crops associate with microorganisms that help their resistance to biotic stress. However, it is not clear how the different partners of this association react during exposure to stress. This knowledge is needed to target the right partners when trying to adapt crops to climate change. Here, we grew wheat in the field under rainout shelters that let through 100%, 75%, 50% and 25% of the precipitation. At the peak of the growing season, we sampled plant roots and rhizosphere, and extracted and sequenced their RNA. We compared the 100% and the 25% treatments using differential abundance analysis. In the roots, most of the differentially abundant (DA) transcripts belonged to the fungi, and most were more abundant in the 25% precipitation treatment. About 10% of the DA transcripts belonged to the plant and most were less abundant in the 25% precipitation treatment. In the rhizosphere, most of the DA transcripts belonged to the bacteria and were generally more abundant in the 25% precipitation treatment. Taken together, our results show that the transcriptomic response of the wheat holobiont to decreasing precipitation levels is stronger for the fungal and bacterial partners than for the plant.
A 1.2V −55°C‐125°C ultra‐low noise bandgap voltage reference without start‐up circuit
Authors: Tao Linzhi , Zhuang Haoyu , Li Qiang 
Published: April 2023

AbstractThis paper proposes a novel bandgap voltage reference (BGR) with low temperature coefficient, ultra‐low noise and without start‐up circuit. Designed in a TSMC 180‐nm CMOS technology, this bandgap voltage reference operates in the temperature range of −55 to 125°C with 5‐V voltage supply and provides a 1.2‐V output voltage VBG. A 16.8 ppm/°C temperature coefficient (TC) and the output RMS noise from 0.1 to 10 Hz of 1.69 µV is achieved. The circuit‐level simulation results verify the presented structure. By the improved architecture of the IPTAT generation stage, the proposed BGR can be powered on normally without designing additional start‐up circuit to eliminate equilibrium point, which greatly simplifies the circuit complexity.

Published: April 2023

AbstractThis letter proposes a novel bandgap reference circuit that utilizes both curvature and folding compensation to achieve a temperature coefficient (TC) of 2.23 ppm/°C. Unlike traditional BGRs, the unique folding compensation method of this circuit improves the performance at low temperature and can also be applied within a specific temperature range.
AN SiC‐based soft‐switching and self‐power supply MMC for MVDC
Authors: Zhang Shaohua , Sun Lejia , Xue Xuan , Lv Hongliang , Jia Renxu 
Published: April 2023

AbstractHere, a novel modular multilevel converter (MMC) and its associated control scheme are proposed for medium‐voltage direct‐current (MVDC) distribution systems. The voltage gain and power can achieve wide‐range expansion by expanding sub‐modules. The voltage, current, and power are shared among all sub‐modules. In addition, all semiconductor devices implement soft switching under low voltage stress and current stress by introducing an auxiliary cell in each sub‐module. By reasonably distributing the energy collected in the soft switching process, the converter realizes the self‐power supply for the drive control circuit of the high‐potential semiconductor switches, wherein the sub‐modules are turned on step by step. The structure of the converter is described and its working principle and control strategy are analyzed in detail. Finally, a 1.8 kW experimental prototype based on SiC devices is provided to achieve an efficiency of 97.3%.
Efficient face image super‐resolution with convenient alternating projection network
Authors: Chen Xitong , Wu Yuntao , Chen Jiangchuan , Wang Jiaming , Zeng Kangli 
Published: April 2023

AbstractThe existing deep learning‐based face super‐resolution techniques can achieve satisfactory performance. However, these methods often incur large computational costs, and deeper networks generate redundant features. Some lightweight reconstruction networks also present limited representation ability because they ignore the entire contour and fine texture of the face for the sake of efficiency. Here, the authors propose a convenient alternating projection network (CAPN) for efficient face super‐resolution. First, the authors design a novel alternating projection block cascaded convolutional neural network to alternately achieve content consistency and learn detailed facial feature differences between super‐resolution and ground‐truth face images. Second, the self‐correction mechanism enabled the convolutional layer to capture faithful features that facilitate adaptive reconstruction. Moreover, a convenient connection operation can reduce the generation of redundant facial features while maintaining accurate reconstruction information. Extensive experiments demonstrated that the proposed CAPN can effectively reduce the computational cost while achieving competitive qualitative and quantitative results compared to state‐of‐the‐art super‐resolution methods.
Intelligent reflecting surface‐aided Doppler compensation for Low‐Earth orbit satellite networks: Joint power allocation and passive beamforming optimisation
Authors: Lee Jaein , Lee Juhwan , Toka Mesut , Shin Wonjae , Lee Jungwoo 
Published: April 2023

AbstractDue to the reduction in costs of manufacture and launch of Low‐Earth orbit (LEO) satellites, LEO satellite communication (SATCOM) has become a promising solution to provide high data rates and low latency connectivity for future communications. However, due to the fast movement of LEO satellites, it has to face a large Doppler effect, leading to high inter‐carrier interference (ICI) power and severe received symbol error rate. To tackle this problem, a novel optimisation framework is proposed that boosts the achievable rate in LEO SATCOM networks by utilising passive beamforming of intelligent reflecting surface (IRS) to compensate for the Doppler effect. First, a carrier‐to‐interference‐noise ratio (CINR) was derived for each subcarrier and a joint optimisation problem of both power allocation is formulated to each subcarrier and passive beamforming of IRS. Moreover, a simultaneous iterative‐water‐filling‐algorithm (SIWFA) and semidefinite programing (SDP) are utilised, thereby striking a balance that minimises ICI power and maximises desired signal power. Numerical results demonstrate the superior achievable rate performance of the proposed IRS‐aided Doppler compensation for LEO SATCOM networks compared to benchmark schemes.

Abstract
Introduction For some patients, undergoing medical treatment for infertility is a cause of major emotional stress which the couple needs to deal with together; it can be said that
infertility is a shared stressor. From the literature it is known that a subjectively perceived sense of self-efficacy supports the patient’s ability to cope adaptively with an illness. As
the basis for this study, we assumed that high levels of self-efficacy are associated with low psychological risk scores (e.g., for anxiety or depressiveness), both in the patient
themselves and in their partner. Accordingly, in infertility patients, targeted support to promote helpful self-efficacy expectations could represent a new counselling strategy that could
enable psychologically vulnerable patients to better cope with the treatment procedure and treatment failures of medically assisted reproduction, making these patients less at risk with
regard to psychosocial factors.
Methods 721 women and men attending five fertility centers in Germany (Heidelberg, Berlin), Austria (Innsbruck), and Switzerland (St. Gallen, Basel) completed the SCREENIVF-R
questionnaire to identify psychological risk factors for amplified emotional problems, as well as the ISE scale to measure self-efficacy. Using paired t-tests and the actor–partner
interdependence model, we analyzed the data of 320 couples.
Results Considering the study participants as couples, women had a higher risk score than men for four out of five risk factors (depressiveness, anxiety, lack of acceptance,
helplessness). In all of the risk areas, it was possible to identify a protective effect from self-efficacy on the patient’s own risk factors (actor effect). There was a negative
correlation between the men’s self-efficacy level and the women’s feelings of depressiveness and helplessness (partner effect, man → woman). The women’s self-efficacy levels had a positive
correlation with acceptance and access to social support in the men (partner effect, woman → man).
Conclusion Because infertility is generally something that a couple has to deal with together, future studies should focus on couples as the unit of analysis instead of just
analyzing the men and women separately. In addition, couples therapy should be the gold standard in psychotherapy for infertility patients.

“LT3-Treated” Protocols of Short-Term Hypothyroidism Induction
in Differentiated Thyroid Cancer: An Analysis of Hypothyroid Complications, Mood
Disorders, and Quality of Life

Published: April 2023

AbstractThis study aimed to compare “non-treated” versus
“levotriiodothyronine (LT3)-treated” protocols of short-term
hypothyroidism induction prior to radioactive iodine (RAI) ablation therapy in
differentiated thyroid cancer (DTC). A total of 120 DTC patients who had
thyroxine withdrawal either via 4-week hypothyroidism induction (non-treated
group, n=60) or 2-week administration and then 2-week withdrawal of LT3
(LT3-treated group, n=60) to induce hypothyroid state prior to RAI
ablation after initial surgery were included. Complications related to
hypothyroidism-induction, Beck Depression Inventory (BDI), Hospital
Anxiety-Depression Scale (HADS), and SF-36 health-related quality of life
(HRQoL) scores were recorded. In the non-treated group, transition from
euthyroid to hypothyroid state was associated with significant increase in the
likelihood of moderate-to-severe depression on BDI (p<0.001), presence
of depression on HADS-D (p<0.001), presence of anxiety on HADS-A
(6.7% during euthyroid state vs. 33.3% during hypothyroid state,
p<0.001), and major syndrome on BPRS (0.0 vs. 10.0%,
p=0.001) as well as significant decrease in all SF-36 HRQoL domain
scores (p<0.001 for each). In conclusion, our findings indicate the
likelihood of L3-treatment to enable a more favorable transition period from
euthyroid to hypothyroid state without experiencing a deterioration in
depression, anxiety, or HRQoL.

Abstract
Background The posterior ledge (PL) is a vital structure that supports the implant posteriorly during orbital floor reconstruction. This study describes a technique for mapping the PL in relation to the infraorbital margin (IM) in patients with orbital floor blowout fractures. This study establishes the location of the optic foramen in relation to the PL.
Methods Facial computed tomography (FCT) scans of 67 consecutive patients with isolated orbital floor blowout fractures were analyzed using Osirix. Planes of reference for orbital fractures, a standardized technique for performing measurements on FCT, was used. Viewed coronally, the orbit was divided into seven equal sagittal slices (L1 laterally to L7 medially) with reference to the midorbital plane. The distances of PL from IM and location of optic foramen were determined.
Results The greatest distance to PL is found at L5 (median: 30.1 mm, range: 13.5–37.1 mm). The median and ranges for each slice are as follows: L1 (median: 0.0 mm, range: 0.0–19.9 mm), L2 (median: 0.0 mm, range: 0.0–21.5 mm), L3 (median: 15.8 mm, range: 0.0–31.7 mm), L4 (median: 26.1 mm, range: 0.0–34.0 mm), L5 (median: 30.1 mm, range: 13.5–37.1 mm), L6 (median: 29.0 mm, range: 0.0–36.3 mm), L7 (median: 20.8 mm, range: 0.0–39.2 mm). The median distance of the optic foramen from IM is 43.7 mm (range: 37.0– 49.1) at L7.
Conclusion Distance to PL from IM increases medially until the L5 before decreasing. A reference map of the PL in relation to the IM and optic foramen is generated. The optic foramen is located in close proximity to the PL at the medial orbital floor. This aids in preoperative planning and intraoperative dissection.

Abstract
Objectives The purpose of this pilot study is to assess the United Arab Emirates dentists' preparedness to manage medical emergencies.
Materials and Methods Ninety-seven licensed dentists participated in this study. Dentists responded to self-administrated questionnaires that contained 23 questions divided into five parts. The first part collected data on participants' sex, years of experience, and whether they are general dental practitioner (GDP) or specialists. The second part included seven questions that asked participants to indicate if they took medical history, obtained vital signs, and attended basic life support courses. The third part included six multiple choice questions regarding the availability of emergency drugs in the dental clinic. The fourth part consisted of three multiple-choice questions that assessed the dentists' immediate response to a medical emergency. Finally, the fifth part comprised four questions to evaluate the dentists' knowledge of proper treatment of special emergency cases they may encounter in the dental offices.
Results Out of the 97 participants, only 51% (N = 49) indicated that they can handle emergencies such as anaphylactic shock and syncope in the dental office. The majority of the dentists (80%) indicated that they have emergency kits. Only 46% of the specialists and 42% of the GDPs were able to correctly plan extractions in a patient with a prosthetic heart valve. Less than half of the participants (N = 35, 36%) were able to correctly answer the question regarding management of a foreign-body aspiration by attempting Heimlich/Triple maneuver.
Conclusions Within the limitations of this study, dentists need further hands-on training to improve their skills and knowledge about medical emergencies that could occur in the dental settings. Furthermore, we recommend that guidelines should be available in the clinic to strengthen the dentists' ability to deal with medical emergencies.

Authors: Sharma Vikas , Dua Sanjeev , Ambastha Rooma 
Published: April 2023

AbstractParagangliomas of spine are rare neuroendocrine tumors. They are World Health Organization grade 1 tumors with common location in cauda equina and filum terminale. We report a case of conus paraganglioma. A 57-year-old lady was admitted with low back pain with radiculopathy without bowel and bladder complaints. Magnetic resonance imaging (MRI) lumbosacral spine showed well-defined round-to-oval extramedullary lesion isointense on T1 and hyperintense on T2-weighted images at the level of L1 vertebra (suggestive of) neurogenic tumor. Intraoperatively reddish-brown capsulated tumor arising from conus with extension to filum and compressing the nerve roots was seen. Gross total excision of tumor was done. Microscopic examination showed well-encapsulated cellular tumor composed of sheets, anastomosing lobules, and nests of small, oval-to-round cells interspersed with blood vessels with mild nuclear atypia and occasional mitosis. Immunohistochemistry analysis was positive for synaptophysin and chromogranin suggestive of paraganglioma. Postoperative period was uneventful. MRI of dorso-lumbar spine showed no residual tumor. Patient was asymptomatic 5 months after surgery. The clinical, radiological, and pathological features of this rare tumor entity is presented.

Abstract
Objective Stem cells of human exfoliated deciduous teeth (SHED) metabolites are secreted molecules from SHED, namely cytokines, chemokines, and growth factors. The metabolite can be used in various regenerative therapy based on cell-free immunomodulatory potential effects, like interleukin 10 (IL-10) and LL37. This molecule can stimulate with epigallocatechin gallate (EGCG) and α-mangosteen and has been proven to have anti-inflammatory and antibacterial effects. This study aimed to identify the effect of EGCG and α-mangosteen to SHED metabolite, called SHED-IL10 and SHED-LL37, from six passages to obtain the optimum stimulation and able to use as periodontitis regeneration treatment.
Materials and Methods The six different passages of SHED were prepared in Dulbecco's modified Eagle medium and added with EGCG 80% (10 μM), EGCG 95% (10 μM), or α-mangosteen (10 μM). After a 24 hours incubation, each passage was measured with the metabolite concentration, SHED-IL10 and SHED-LL37, with human IL-10 and LL37 using enzyme-linked immunosorbent assay. Each different concentration was then analyzed statistically.
Results The addition of EGCG 95% is able to stimulate the SHED-IL10 optimum concentration in passage 1 (p < 0.01). But, in the different conditions, the addition of EGCG 80%, EGCG 95%, and α-mangosteen was able to stimulate the SHED-LL37 optimum concentration in passage 2 (p < 0.001).
Conclusion The addition of EGCG and α-mangosteen can stimulate the SHED-IL10 and SHED-LL37 concentrations. These two metabolites are promising as regenerative therapy through anti-inflammatory and antibacterial properties.

Abstract
Objectives The aim of this study was to determine the prevalence of malocclusion and its associated demographic and clinical factors in young adolescents (13–15 years) of Karachi, Pakistan.
Materials and Methods An epidemiological survey included 500 young adolescents of registered schools, madrassas (Islamic education system), and shop workers of Gulshan-e-Iqbal Town. It was a cross-sectional analytical study design. Multistage random sampling technique was used to enroll participants. The pattern of occlusion was recorded with other related features using Angle's classification. Health status was recorded through World Health Organization-guided indices (decayed, missing, and filled permanent teeth [DMFT], community periodontal index of treatment needs [CPITN], and body mass index [BMI]). The information, thus, obtained was analyzed through SPSS using the chi-squared test and regression models.
Results Forty four percent of the participants were female, while overall estimated prevalence of malocclusion in young adolescents of Karachi was 57.4%. After adjustments, participants going to any kind of education system had less malocclusion in comparison to those who were not going to any education system (adjusted odds ratio [aOR] = 0.305, 95% confidence interval [CI] = 0.12–0.73); mother's education especially higher level (aOR = 2.02, 95% CI = 1.08–3.75) and presence of periodontal disease (aOR = 1.57, 95% CI = 1.06–2.33) were significantly associated with malocclusion.
Conclusion This study showed that the class I malocclusion is prevalent in the local community. Demographic factors like gender, age, self-reported ethnicity, and BMI did not show any significant role. Education or knowledge of parents and young adolescents does play an influential role in decreasing malocclusion. Young adolescents, who are more prone to oral health problems at an early age, would have more chances to develop occlusal discrepancies.
