Traditionally B3 breast lesions are treated surgically, but overtreatment is a concern, as the majority have a final benign diagnosis. A national screening program introduced vacuum-assisted excision (VAE) for managing B3 lesions in late 2016. This retrospective study aimed to assess the outcomes associated with this approach.All B3 lesions diagnosed between 01/2017 and 12/2019 were identified at two centres. Information was obtained on the initial biopsy and final histology, and method of VAE image guidance, needle size and number of cores. Lesions were excluded if there was cancer elsewhere in the breast at the time of diagnosis; the lesion was not suitable for VAE due to position in the breast or had B3 pathology for which open biopsy was still required. The final decision to offer VAE was always made at a multidisciplinary meeting (MDM). Risk difference was used to test the significance at p ≤ .05.In total, 258 B3 lesions were diagnosed, 105 (40.7%) met the inclusion criteria and underwent VAE. VAE was performed under X-ray (89/105) or ultrasound guidance (16/105), taking an average of 18.5 cores with the 10-G needle or 10.8 cores with the 7-G needle. Nine cases (8.6%) were upgraded to a malignant diagnosis following VAE. Malignancy was found in 15.5% (9/58) of B3 lesions with epithelial atypia, but in none without atypia (0/47) (p = .004). No new lesions or malignancy has occurred at the site of the VAE with an average mammographic follow-up of 2.2 years.Upgrade to malignancy following VAE was uncommon (8.6%) and associated with atypia in the initial biopsy. VAE is an alternative approach to the management of B3 lesions, reducing open surgical procedures.• Upgrade to malignancy after a vacuum-assisted excision of a B3 breast lesion is uncommon with an 8.6% upgrade rate. • The risk of a malignant diagnosis after a vacuum-assisted excision was significantly higher for B3 lesions with atypia compared to those without (+15.5% difference, p = .004).

Background We aimed to assess the gene expression profiles of uninflamed small bowels in patients with Crohn’s disease (CD) to identify its accompanying molecular alterations. Methods We performed RNA sequencing of the uninflamed small bowel tissues obtained from 70 patients with ileal CD, and 9 patients with colon cancer (non-CD controls) during bowel resection. Differentially expressed gene (DEG) analyses were performed using DESeq2. Gene set enrichment, correlation, and cell deconvolution analyses were applied to identify modules and functionally enriched transcriptional signatures of CD. Results A comparison of CD patients and non-CD controls revealed that of the 372 DEGs, 49 protein-coding genes and 5 lncRNAs overlapped with the IBD susceptibility loci. The pathways related to immune and inflammatory reactions were upregulated in CD, while metabolic pathways were downregulated in CD. Compared with non-CD controls, CD patients had significantly higher proportions of immune cells, including plasma cells (P=1.15×10-4), and a lower proportion of epithelial cells (P=1.12×10-4). Co-upregulated genes (M14 module) and co-downregulated genes (M9 module) were identified in CD patients. The M14 module was enriched in immune-related genes and significantly associated with the responses to anti-TNF therapy. Intestinal tissue transcriptomic analysis of 3 independent cohorts, identified M14 module upregulation in non-responders at baseline, which was predictive of response with acceptable discrimination ability (area under the curve of 77~83%). Conclusion The differences in gene expression and cellular composition between CD patients and non-CD controls imply significant molecular alterations, which are associated with the response to anti-TNF treatment.

To evaluate the relationship between dental calcification and skeletal maturity and to identify the tooth with the highest correlation with skeletal maturity index in Korean children.For 447 children (205 boys and 242 girls) aged between 5 and 13 years, hand-wrist and lateral cephalometric radiographs were taken to assess skeletal maturity by Fishman's skeletal maturity indicators (SMI) and Baccetti's cervical vertebrae maturation (CVM) stages. Dental panoramic radiographs were taken to assess dental maturity of the permanent mandibular canine, first and second premolar, and second molar using the method devised by Dermirjian.Dental calcification stages determined by panoramic radiographs can be clinically used as useful indices to predict skeletal maturity in Korean children.

Aims The aims of this study were to review the histological features useful for the identification of metastases to the breast and to investigate the impression that this diagnosis has become more common. Methods and results The histological features of metastases to the breast from 2008 to 2018 were reviewed. Seventy-four biopsies from 66 patients were identified: 1% compared with primary carcinoma of the breast. Non-haematological metastases comprised 0.75% compared with 0.3% in a series from 1996 to 2005. The most common tumour types were pulmonary carcinoma (22), lymphoma (15), melanoma (13), gastrointestinal carcinoma (eight) and serous papillary carcinoma (four). In 73% there were histological features that were not typical of primary mammary carcinoma. Some metastases were histologically similar to breast cancer and the history was essential to making the correct diagnosis. Useful histological clues included small-cell morphology for pulmonary carcinoma, glands containing necrosis for gastrointestinal carcinoma, intranuclear inclusions, marked pleomorphism and spindle cells for melanoma, clear cells for renal carcinoma, papillary architecture for serous papillary carcinoma and sheets of centroblasts or nodules of centroblasts and centrocytes for lymphoma. Useful immunohistochemical markers included TTF-1 for pulmonary carcinoma, S100, melan-A and HMB45 for melanoma, CK20 and CDX2 for colorectal carcinoma, PAX8 and WT1 for serous papillary carcinoma and lymphoid markers for lymphomas, in addition to the absence of expression of mammary markers ER, GATA3 and GCDFP-15. Conclusion The majority of metastases to the breast have histological clues to the diagnosis. Immunohistochemistry is helpful. This diagnosis is being made more frequently.

A 40-year-old woman with silicone implants inserted 21 years before presented with sudden onset of painful right breast swelling. Clinical examination revealed a firm swollen breast with appearance of old bruising. Ultrasound showed fluid around the implant. Cytology of the fluid showed cells with large pleomorphic nuclei with prominent nucleoli including elongated forms and very occasional vacuoles. The cell block also contained small fragments with atypical spindle cells around slit-like spaces that were positive for CD31 and CD34. MRI showed a 25 mm serpiginous area of enhancement on the inner aspect of the fibrous capsule with haematoma between the capsule and the implant. The capsule and adjacent area were excised. Histology showed angiosarcoma extending from the inner aspect of the capsule into the cavity around the implant. The location of the tumour on the inner aspect of the capsule is the same site that breast implant associated anaplastic large cell lymphomas arise and suggests a possible causal link between the implant and the angiosarcoma. This case emphasises the value of cytological assessment of fluid around breast implants and the role of cell blocks and immunohistochemistry.

AMoRE is an international project to search for the neutrinoless double beta decay of $^{100}$Mo using a detection technology consisting of magnetic microcalorimeters (MMCs) and molybdenum-based scintillating crystals. Data collection has begun for the current AMORE-I phase of the project, an upgrade from the previous pilot phase. AMoRE-I employs thirteen $^\mathrm{48depl.}$Ca$^{100}$MoO$_4$ crystals and five Li$_2$$^{100}$MoO$_4$ crystals for a total crystal mass of 6.2 kg. Each detector module contains a scintillating crystal with two MMC channels for heat and light detection. We report the present status of the experiment and the performance of the detector modules., Comment: 8 pages, 4 figures, published in Journal of Low Temperature Physics (2022)

General Medicine ,General Chemistry - Abstract
Cement is the primary ingredient in concrete, which is one of the crucial building materials. The evolution of greenhouse gases, particularly carbon dioxide, which is produced during the hydration stage, has increased because of excessive use of concrete. Geopolymer, an alumina-silicate based bonding substance is made up of waste materials such as Fly ash (FA) or Silica Fume (SF) in the presence of alkaline solutions has been developed to reduce the effect of carbon emissions on the environment. This paper studied the optimization and utilization of FA and SF replacement as pozzolanic materials for the development of sustainable geopolymer mortar and to achieve optimal mechanical strength using response surface methodology (RSM). According to the study, with the addition of 90% FA and 10% SF content to the geopolymer design mix significantly improves their mechanical properties. When SF and sodium hydroxide are combined to create geopolymer mortar, they work as an alkaline catalyst, dramatically reducing carbon emission of the waste materials and providing it an edge over cement-based mortar. The construction of self-sustaining infrastructures ensuring human safety and eco-friendly practices will be encouraged by the multi-objective approach of RSM.

Hypericin, a naphthodianthrone, has been identified as the principal active compound found in St. John's wort (Hypericum perforatum L.). To generate a gene resource for hypericin and other valuable metabolites, we generated expressed sequence tags (ESTs) from H. erectum. Analyses of the ESTs enabled us to select three cDNAs, HeHyp1, HeHyp2, and HeHyp3, evidencing significant sequence homology to Hyp-1 that were involved in hypericin biosynthesis from H. erectum. The deduced amino acid sequence of HeHyp1 cDNA exhibits 95 % identity with Hyp-1. The HeHyp2 and HeHyp3 polypeptides also exhibit 81.1 % identity with Hyp-1. The transcripts of HeHyp1, HeHyp2, and HeHyp3 were detected in the root, stem, leaf, flower, and callus cells. Study using recombinant protein suggests that Hyp-1, HeHyp2, and HeHyp3 may be involved in the biosynthetic of hypericin or other emodin derivatives.

Cancer cells are abnormal cells that do not comply with tissue homeostasis but undergo uncontrolled proliferation. Such abnormality is driven mostly by somatic mutations on oncogenes and tumor suppressors. Cancerous mutations show intra-tumoral heterogeneity across cancer types and eventually converge into the self-activation of proliferative signaling. While transient production of intracellular reactive oxygen species (ROS) is essential for cell signaling, its persistent production is cytotoxic. Thus, cancer cells require increased levels of intracellular ROS for continuous proliferation, but overexpress cellular peroxidase enzymes, such as 2-Cys peroxiredoxins, to maintain ROS homeostasis. However, suppression of 2-Cys peroxiredoxins has also been reported in some metastatic cancers. Hence, the cancer-associated functions of 2-Cys peroxiredoxins must be illuminated in the cellular context. In this review, we describe the distinctive signaling roles of 2-Cys peroxiredoxins beyond their intrinsic ROS-scavenging role in relation to cancer cell death and survival.

Abnormal storm waves cause coastal disasters along the coasts of Korean Peninsula and Japan in the East/Japan Sea (EJS) in winter, arising due to developed low pressures during the East Asia winter monsoon. The generation of these abnormal storm waves during rough sea states were studied and hindcast using an atmosphere-wave coupled modelling system. Wind waves and swell due to developed low pressures were found to be the main components of abnormal storm waves. The meteorological conditions that generate these waves are classified into three patterns based on past literature that describes historical events as well as on numerical modelling. In hindcasting the abnormal storm waves, a bogussing scheme originally designed to simulate a tropical storm in a mesoscale meteorological model was introduced into the modelling system to enhance the resolution of developed low pressures. The modelling results with a bogussing scheme showed improvements in terms of resolved low pressure, surface wind field, and wave characteristics obtained with the wind field as an input.

A 63-year-old woman presented with a clinically malignant mass. Core biopsy showed features resembling endometriosis. The glands were GATA3 and oestrogen receptor positive consistent with mammary origin and had no myoepithelial layer. The excision also showed a fibroepithelial component with stromal overgrowth, frequent mitoses and invasive margin consistent with a malignant phyllodes tumour. KMT2D and SETD2 mutations were present in both the conventional phyllodes tumour and endometriosis-like areas and are also described in endometriosis raising interesting questions about these lesions. This unusual pattern is a potential diagnostic pitfall, so it is helpful to be aware of it.

At the Fermilab Tevatron proton-antiproton ($p\bar{p}$) collider, high-mass electron-neutrino ($e\nu$) pairs are produced predominantly in the process $p \bar{p} \rightarrow W(\rightarrow e\nu) + X$. The asymmetry of the electron and positron yield as a function of their pseudorapidity constrain the slope of the ratio of the $u$- to $d$-quark parton distributions versus the fraction of the proton momentum carried by the quarks. This paper reports on the measurement of the electron-charge asymmetry using the full data set recorded by the Collider Detector at Fermilab in 2001--2011 and corresponding to 9.1~fb$^{-1}$ of integrated luminosity. The measurement significantly improves the precision of the Tevatron constraints on the parton-distribution functions of the proton. Numerical tables of the measurement are provided.

Post-traumatic stress disorder (PTSD) is characterized by neurophysiological and psycho-emotional problems after exposure to trauma. Several pharmacological and psychotherapy limitations, such as adverse events and low adherence, increase the need for alternative therapeutic options. Neurofeedback is widely used for PTSD management. However, evidence of its clinical efficacy is lacking. We conducted a randomized, waitlist-controlled, assessor-blinded clinical trial to assess the effectiveness, cost-utility, and safety of 16 sessions of neurofeedback on people with PTSD for eight weeks. Eleven participants were allocated to each group. One and two subjects dropped out from the neurofeedback and control groups, respectively. The primary outcome was PTSD symptom change evaluated using the PTSD Checklist-5 (PCL-5-K). The PCL-5-K levels improved more in the neurofeedback group (44.3 ± 10.8 to 19.4 ± 7.75) than in the control group (35.1 ± 18.5 to 31.0 ± 14.92). The change value was significantly improved in the neurofeedback group (24.90 ± 13.13 vs. 4.11 ± 9.03). Secondary outcomes such as anxiety, depression, insomnia, and quality of life were also improved. In an economic analysis using EuroQol-5D, the incremental cost-per-quality-adjusted life-year was approximately $15,600, indicating acceptable cost-utility. There were no adverse events in either group. In conclusion, neurofeedback might be a useful, cost-effective, and safe intervention for PTSD management.

Long term observations of full-disk Lyman-α irradiance have been made by the instruments on various satellites. In addition, several sounding rockets dating back to the 1950s and up through the present have measured the Lyman-α irradiance. Previous full disk Lyman-α images of the sun have been very interesting and useful scientifically, but have been only five-minute ``snapshots" obtained on sounding rocket flights. All of these observations to date have been snapshots, with no time resolution to observe changes in the chromospheric structure as a result of the evolving magnetic field, and its effect on the Lyman-α intensity. The Lyman-α Imaging Solar Telescope(LIST) can provide a unique opportunity for the study of the sun in the Lyman-α region with the high time and spatial resolution for the first time. Up to the 2nd year development, the preliminary design of the optics, mechanical structure and electronics system has been completed. Also the mechanical structure analysis, thermal analysis were performed and the material for the structure was chosen as a result of these analyses. And the test plan and the verification matrix were decided. The operation systems, technical and scientific operation, were studied and finally decided. Those are the technical operation, mechanical working modes for the observation and safety, the scientific operation and the process of the acquired data. The basic techniques acquired through the development of satellite based solar telescope are essential for the construction of space environment forecast system in the future. The techniques which we developed through this study, like mechanical, optical and data processing techniques, could be applied extensively not only to the process of the future production of flight models of this kind, but also to the related industries. Also, we can utilize the scientific achievements which are obtained throughout the project. And these can be utilized to build a high resolution photometric detectors for military and commercial purposes. It is also believed that we will be able to apply several acquired techniques for the development of the Korean satellite projects in the future.

In this study, we attempt to detect snow cover area using multi-temporal geostationary satellite imagery based on the difference of spectral and temporal characteristics between snow and clouds. The snow detection method is based on sequential processing of simple thresholds on multi-temporal GOCI data. We initially applied a simple threshold of blue reflectance and then root mean square deviation (RMSD) threshold of near infrared (NIR) reflectance that were calculated from time-series GOCI data. Snow cover detected by the proposed method was compared with the MODIS snow products. The proposed snow detection method provided very similar results with the MODIS cloud products. Although the GOCI data do not have shortwave infrared (SWIR) band, which can spectrally separate snow cover from clouds, the high temporal resolution of the GOCI was effective for analysing the temporal variations between snow and clouds.

Background Although high and low volume polyethylene glycol(PEG) bowel preparations are recommended for patients with inflammatory bowel disease(IBD) before colonoscopy, sometime it is limited due to poor compliance. So, studies regarding novel low volume preparations in IBD are need, but, there is limited data. We aimed to evaluated the safety, tolerability and efficacy of oral sulfate tablet (OST) by comparison with 2L PEG and ascorbate (PEG/Asc) in patients with IBD. Methods One hundred ten patients with IBD were enrolled in this single-blind, multicenter, non-inferiority study. Patients were assigned either 2L PEG/Asc or OST to be administered in a split-dose regimen. OST patients were administered 14 tablets with more than 1L of free water in the evening, and the following morning. Colonoscopies were performed by blinded investigators. The primary efficacy endpoint was successful bowel cleansing rate, defined as Harefield Cleansing Scale grade A or B as evaluated by blinded endoscopist in each hospital. Secondary endpoints included the presence of residual air bubbles. Adverse events and laboratory evaluations were monitored to assess safety. Flare up of IBD symptoms and mucosa change associated with preparation were also evaluated. Tolerability, in terms of taste and degree of resistance to drink was assessed with VAS score by interview before colnoscopy. Safety was assessed by spontaneously reported adverse events, solicited ratings of expected prep symptoms, and laboratory testing. Results The cleansing score at all the segment was significantly higher in OST group. A high rate of cleansing success was seen with OST (98.1%), which was noninferior to 2L PEG/Asc (98.1%). Proportion of patients with bubble score 0 was significantly higher in OST than 2L PEPG/Asc group (94.5% vs. 50.0%, p Conclusion Oral sulfate tablets achieved a high level of cleansing comparable with 2L PEG/Asc in patients with IBD. The risk of mucosal change or symptom relapse were not higher, on the other hand the degree of satisfaction was higher than 2L PEG/Asc. OST split method could be considered as one of the preparation method for patients with inactive IBD.

© 2019, Cancer Research UK. Background: Previous studies have reported up to 50% of ductal carcinoma in situ (DCIS), is HER2 positive, but the frequency of HER2-positive invasive breast cancer (IBC) is lower. The aim of this study is to characterise HER2 status in DCIS and assess its prognostic value. Methods: HER2 status was evaluated in a large series of DCIS (n = 868), including pure DCIS and DCIS associated with IBC, prepared as tissue microarrays (TMAs). HER2 status was assessed using immunohistochemistry (IHC) and chromogenic in situ hybridisation (CISH). Results: In pure DCIS, HER2 protein was over-expressed in 9% of DCIS (3+), whereas 15% were HER2 equivocal (2+). Using CISH, the final HER2 status was positive in 20%. In mixed DCIS, HER2 amplification of the DCIS component was detected in 15% with amplification in the invasive component of only 12%. HER2-positive DCIS was associated with features of aggressiveness (p < 0.0001) and more frequent local recurrence (p = 0.03). On multivariate analysis, combined HER2+/Ki67+ profile was an independent predictor of local recurrence (p = 0.006). Conclusions: The frequency of HER2 positivity in DCIS is comparable to IBC- and HER2-positive DCIS is associated with features of poor prognosis. The majority of HER2 over-expression in DCIS is driven by gene amplification.

The performance of the prototype modules of neutron detectors for the Large Acceptance Multi-Purpose Spectrometer (LAMPS) was investigated, using cosmic muons and neutron beams at 65 and 392 MeV, provided by the Research Center for Nuclear Physics (RCNP). The timing and position resolutions were estimated using cosmic muons as 309 ps and 4.8 cm, respectively. The energy resolution depended on the incident energy of neutrons: 1.3% at 65 MeV and 3.1% at 392 MeV. The neutron-detection efficiency also showed weak energy dependence as it decreased from (9.0 ± 1.6)% at 65 MeV to (6.3 ± 1.0)% at 392 MeV.

Background The ASCO/CAP guidance on HER2 testing in breast cancer (BC) has recently changed. Group 2 tumours with immunohistochemistry score 2+ and HER2/CEP17 ratio ≥2.0 and HER2 copy number Methods 749 BC cases were identified from 11 institutions. The association between HER2 groups and pathological complete response (pCR) was assessed. Results 54% of immunohistochemistry HER2 positive (score 3+) BCs showed pCR, compared to 19% of immunohistochemistry 2+ FISH amplified cases. 27% of Group 2 treated with HER2 targeted therapy achieved pCR, compared to 19 and 11% in the combined Groups 1 + 3 and Groups 4 + 5, respectively. No difference in pCR rates was identified between Group 2 and Group 1 or combined Groups 1 + 3. However, Group 2 response rate was higher than Groups 4 + 5 (p = 0.017). Conclusion No difference in pCR was detected in tumours with a HER2/CEP17 ratio ≥2.0 and a HER2 score 2+ by IHC when stratified by HER2 gene copy number. Our data suggest that ASCO/CAP HER2 Group 2 carcinomas should be evaluated further with respect to eligibility for HER2 targeted therapy.

OBJECTIVE To quantify familial risk of endometriosis among full siblings and examine interactions between family history and smoking, age at menarche or body mass index (BMI). DESIGN, SETTING AND POPULATION Population-based nationwide cohort study. METHODS Using data from the Korean National Health Insurance and Screening Programme databases on kinship, healthcare utilisation, lifestyle and anthropometrics, we identified 2 109 288 women with full siblings and their environmental risk factors from 2002 to 2018. Familial risks were estimated using Cox proportional-hazards models, represented as incidence risk ratios (IRR) with 95% CI. Interaction between family history and smoking, age at menarche or BMI were assessed on an additive scale. MAIN OUTCOME MEASURES IRR of endometriosis among women with and without affected siblings. RESULTS From 19 195 women with affected siblings, 1126 developed endometriosis with an incidence of 35.45/10 000 person-years. Familial risk of endometriosis with versus without affected siblings was increased to IRR 2.75 (95% CI 2.25-3.36), and the highest risk was with affected twins (IRR 6.98; 95% CI 4.19-11.62). Women with both a family history and either smoking, early menarche or low BMI had a significantly higher risk of endometriosis compared with the general population and can be regarded as a high-risk group, the IRRs were 4.28 (95% CI 2.43-7.55), 3.47 (95% CI 2.82-4.26) and 3.09 (95% CI 2.68-3.56), respectively. Substantial effect modification of the associations was noted by smoking and early menarche, as their combined risk with family history exceeded the sum of their individual risks, which was also statistically significant. CONCLUSION Genetic factors are the primary contributor to the familial aggregation of endometriosis. Significant gene-environment interaction exists between family history and smoking or early menarche. TWEETABLE ABSTRACT Significant gene-environment interaction exists between family history of endometriosis and smoking or early menarche.

Fibroepithelial tumours of the breast are biphasic neoplasms composed of both epithelial and stromal elements, including the common fibroadenoma and the infrequent phyllodes tumour. The admixture of epithelium and stroma in the fibroadenoma shows intra- and pericanalicular patterns, and may display a variety of histological changes. Fibroadenoma variants include the cellular, juvenile, myxoid and complex forms. The cellular fibroadenoma may be difficult to distinguish from the benign phyllodes tumour. Stromal mitotic activity can be increased in fibroadenomas in the young and pregnant patients. Phyllodes tumours, neoplasms with the potential for recurrence, show an exaggerated intracanalicular growth pattern with broad stromal fronded architecture and stromal hypercellularity. They are graded into benign, borderline and malignant forms based on histological assessment of stromal features of hypercellularity, atypia, mitotic activity, overgrowth and the nature of the tumour borders. Classification of phyllodes tumours is imperfect, compounded by tumour heterogeneity with overlapping microscopic features among the different grades, especially in the borderline category. Malignant phyllodes tumours can metastasise and cause death. Determining which phyllodes tumours may behave aggressively has been difficult. The discovery of MED12 mutations in the pathogenesis of fibroepithelial tumours, together with other gene abnormalities in the progression pathway, has allowed refinements in diagnosis and prognosis.

The present work was designed to synthesize novel NaY and Ni modified NaY (Ni-NaY) zeolites for efficient removal of phenol from aqueous solution. The Ni-NaY (FAU, Si/Al = 2.56) was prepared by ion-exchange method at 873 K and pH = 5.8. The characterization of NaY and Ni-NaY was done by EDX, FTIR, ATD/TGA, BET, SEM, and XRD. Characterization results revealed that Ni-NaY showed an increased surface area and pore volume compared to NaY. The phenol adsorption reached the equilibrium within 2 h at pH = 4. A comparative study indicated that Ni-NaY exhibited a high adsorption capacity of phenol compared to NaY, with an average removal of 77.20% and 88.79% by NaY and Ni-NaY, respectively. The low coordination number of Ni cations in NaY structure and the ability of this zeolite to stabilize Ni cations in low-valence states were the main reasons for its superior adsorption performance compared with NaY. The experimental adsorption data were applied to different adsorption and kinetic models to understand the adsorption mechanism. Results indicated that the Freundlich model and pseudo-second order fited the adsorption of phenol on NaY and Ni-NaY. The phenol adsorption on NaY and Ni-NaY zeolite was mediated principally via hydrogen bonding between the hydroxyl (OH) group of phenol and silanol groups of the Ni-NaY zeolite surface. Results also showed that after 5 cycles of regeneration, Ni-NaY had a removal efficiency higher than 90%, which demonstrated an excellent reproducibility of modified zeolite as an adsorbent.

Implantable medical devices (IMDs) for bio-signal sensing and stimulation consume power from micro to milli-watt levels, while requiring continuous data telemetry through uplink and downlink. An inductive link with coupled coils can be a promising solution for efficient near-field wireless power transfer as well as bidirectional data telemetry through the power link without additional coil/antenna. The wireless power/data transfer receiver (WPDT Rx) with inductive links requires high power conversion efficiency (PCE) for safe IMD operation and high data rate for continuous telemetry.
