Data collection techniques through observation, interviews and documents. Data analysis techniques use data reduction, data recitation and conclusion research. The quality of service in this study uses the theories of Parasuraman, Zeithaml, and Berry (2013:23), namely tangibles, reability, responsivess, assurance and empathy. The result of this research is that the quality of IKD services is not optimal, as seen from the tangibles dimension (realized) in the infrastructure and facilities of IKD services and there are still obstacles, namely in the IKD activation procedure due to limited public knowledge.

The Role of Exogenous microRNAs on Human Health: The Plant-Human Trans-Kingdom Hypothesis.

MicroRNAs (miRNAs) are small, endogenous, single-stranded RNAs that act on gene silencing at the post-transcriptional level by binding to a target messenger RNA (mRNA), leading to its degradation or inhibiting translation into functional proteins. The key role of miRNAs in development, proliferation, differentiation andapoptosis has been deeply investigated, revealing that deregulation in their expression is critical in various diseases, such as metabolic disorders and cancer. Since these small molecules initially evolved as a mechanism of protection against viruses and transposable elements, the fascinating hypothesis that they can move between organisms both of the same or different species has been postulated. Trans-kingdom is the term used to define the migration that occurs between species. This mechanism has been well analyzed between plants and their pests, in order to boost defense and increase pathogenicity, respectively. Intriguingly, in the last decades, the plant-human trans-kingdom migration via food intake hypothesis arose. In particular, various studies highlighted the ability of exogenous miRNAs, abundant in the mainly consumed plant-derived food, to enter the human body affecting gene expression. Notably, plant miRNAs can resist the strict conditions of the gastrointestinal tract through a methylation step that occurs during miRNA maturation, conferring high stability to these small molecules. Recent studies observed the anti-tumoral, immune modulator and anti-inflammatory abilities of trans-kingdom interaction between plant and human. Here, we depict the existing knowledge and discuss the fascinating plant-human trans-kingdom interaction, highlighting first the eventual role of plant miRNAs from foods on our somatic gene identity card and then the potential impact of using plant miRNAs as novel therapeutic avenues.

VOTEMAT: A Blockchain Based Voting System

This study aims to show that a secure, trustable and immutable voting system can be established with Blockchain technology. Decentralized structure of the Blockchain excludes the central authority and provides transparency. Moreover, its cryptographic functions enable secure transactions. Therefore, the operation is prevented from potential frauds, such as multiple votes, fake vote attempts, and fraudulent vote counts. The proposed method, VOTEMAT, covers both electronic voting and paper ballot as a complete solution. A mobile application and a Website, connected to Ethereum private Blockchain network, were developed for the voters who prefer to cast their votes remotely. It is also possible to vote in the voting centres via the mobile device or paper ballot placed in the vote boxes; but these votes are also recorded in the same Blockchain and equally secure. For the remote users, a two-step authentication is designed, based on the information on the national identity card and face recognition. An additional encryption based security measure is used to avoid hacking attempts, such as man in the middle attacks. Since the proposed system is more practical than the traditional voting methods, it can increase the participation and be utilized in all kinds of local or national elections.

Image Processing in Improving the Scan Results of Identity Cards and Family Cards with Noise with the Median Filtering Method

In the digital era, identity documents such as Identity Cards and Family Cards play a crucial role in administration and public services. The process of scanning these documents often results in images with noise that can interfere with data accuracy and identification. This research aims to improve the quality of scanned images by using the median filtering method to reduce salt and pepper noise. Median Filtering was chosen for its ability to preserve edges and details in images, which is crucial for identity documents such as Identity Cards and Family Cards. In this study, the system developed to enhance scanned images was implemented and tested. Evaluation results show that the Median Filtering method is effective in removing noise without damaging the edges and fine details of the images. The evaluation indicates that this system is effective in producing images that meet the quality standards required for official administration and identification. This research is expected to contribute to the development of digital image enhancement technology for identity documents, thus improving accuracy and reliability in public services.

Evaluation of Anti-k Antibody in a Patient Undergoing Redo Sternotomy

Abstract Introduction/Objective Introduction: The Kell blood group system, discovered in 1946, holds paramount significance in transfusion medicine and hemolytic disease of the newborn (HDN). Named after Mrs. Kelleher, who exhibited anti-Kell antibodies resulting in HDN, this system comprises 25 antigens, with the original K antigen retaining primary importance. Additionally, Levine et al. identified anti-Cellano, now known as anti-k, presenting an antibody antithetical to anti-K. Methods/Case Report Case Presentation: A 60-year-old male with a history of bioprosthetic aortic valve insufficiency, pulmonary homograft stenosis, and recurrent aortic insufficiency presents for a fourth redo sternotomy for root and ascending aorta replacement. Preoperative assessment revealed a positive antibody screen for anti-k, a clinically significant antibody associated with decreased survival of transfused red blood cells (RBCs). Given limited compatible blood units available, efforts are underway to secure additional donations before the scheduled surgery on 2/22/24. The patient’s medical history indicates no recent blood transfusions or iron therapy, with the last transfusion in 1996. He is anticoagulated with warfarin for mechanical valve and atrial fibrillation, necessitating preoperative bridging with Lovenox injections. Methods The patient’s antibody screen and initial panel demonstrated pan-reactivity with 3+ reactivity, suggesting an antibody targeting a high-frequency antigen. Further testing using polyethylene glycol (PEG) confirmed the presence of anti-k, supported by negative reactions to additional K-negative cells. The absence of other clinically significant antibodies was verified using 0.2 M Dithiothreitol (DTT) modified cells. Results (if a Case Study enter NA) NA Conclusion Conclusion: The identification of anti-k antibody underscores the critical role of preoperative antibody screening in mitigating transfusion-related complications, particularly in patients requiring complex surgical interventions. Collaborative efforts between clinical teams and transfusion medicine specialists are imperative to ensure adequate blood product availability and optimize patient outcomes.To prevent further exposure, it is recommended that patients with rare antibodies carry an Antibody ID card indicating the rare antibody they possess.k antigen blood donors are underrepresented in the general donor pool. It is recommended to develop a systematic recruitment for k antigen donors.

A rare case of Anti-Jk3 Alloimmunization

Abstract Introduction/Objective The Kidd blood group system was discovered in 1951 and consists of two antithetical antigens, Jka and Jkb, in addition to a third high-incidence antigen, Jk3. Jk null, also known as Jk(a-b-), is an extremely rare blood group in which all Kidd antigens are absent. Jk is a urea transporter found in the renal medulla, and Jk-deficient individuals are unable to concentrate urine to its maximum concentration. If these individuals are exposed to the Jk antigen via transfusion or pregnancy, they are able to produce antibodies against the Jk3 antigen with a high incidence. Jk3 is expressed in over 99.9% of the blood donor pool, which has severe clinical implications and complicates transfusion. Methods/Case Report CASE PRESENTATION: A 68-year-old male was admitted to the Stanford Medical Center with chronic right midshaft tibia osteomyelitis and a sinus drainage tract for a right tibial diaphysectomy. His test for antibodies was positive. Plasma from the patient is reactive with all tested cells except auto control, AHG in PEG, and solid phase. Phenotyping yielded negative results for Jka and Jkb, suggesting that the antibody is Jk3. Anti-Jk3 was eliminated by adsorption and rendered nonreactive. Results (if a Case Study enter NA) NA Conclusion Anti-Jk3 should be suspected in a previously pregnant or transfused patient during antibody screening and identification if it demonstrates the pattern of an antibody reacting to all cells in the panel, i.e., reacting to a high- frequency antigen with negative autocontrol. Awareness on the part of blood bank personnel regarding the variability of the blood group phenotype and the capricious nature of Kidd antibodies may aid in the improved management of these patients. It is recommended that patients with rare antibodies carry an antibody ID card indicating the rare antibody they have to prevent further exposure. A patient may be advised to undergo an autologous transfusion. Fortunately, the patient’s procedures were uncomplicated, so a blood transfusion was unnecessary. Awareness on the part of blood bank staff regarding the variability of the blood group phenotype and the unpredictability of Anti-Jk3 may aid in improving patient care. To prevent further exposure, it is recommended that patients with rare antibodies carry an Antibody ID card indicating the rare antibody they possess.Jk3 antigen blood donors are underrepresented in the general donor pool. It is recommended to develop a systematic recruitment for Jk3 antigen donors.

Clinical Identification of Two Novel C. kroppenstedtii-like Species Isolated as Pathogens of Granulomatous Lobular Mastitis.

Granulomatous lobular mastitis (GLM) is a rare benign breast inflammatory disease that affects women of childbearing age. Corynebacterium species, especially Corynebacterium kroppenstedtii, was reported as the pathogen of GLM. A recent study showed that the C. kroppenstedtii complex is composed of C. kroppenstedtii and two novel species, C. parakroppenstedtii and C. pseudokroppenstedtii. The study presents seven C. kroppenstedtii-like strains isolated from GLM patients. However, they turned out to be six strains of C. parakroppenstedtii and one strain of C. pseudokroppenstedtii according to 16sRNA sequencing. In order to conduct a phylogenetic study, we further sequenced the fusA and rpoB genes, which were frequently employed in studies of Corynebacterium species. Novel Mass Spectral Peaks (MSPs) for C. parakroppenstedtii were created with Bruker MALDI-TOF MS. Then, the identification power of the MSPs was tested by C. parakroppenstedtii strains and remotely related Corynebacterum spp. The antibiotic sensitivity tests were performed according to the CLSI M45 guidelines. All of the strains were not resistant to β-lactams, vancomycin or linezolid. However, applying erythromycin and clindamycin could be fruitless. Phenotypic identification using a Vitek2 ANC ID card proved all of the C. parakroppenstedtii strains were identified as Actinomycete naeslundii. The test of Ala-Phe-Pro arylamidase and urease could be employed as the characteristics to distinguish C. pseudokroppenstedtii from C. parakroppenstedtii. Here, we present the identification, antibiotic sensitivity tests (ASTs) and epidemiological investigation of two novel C. kroppenstedtii-like species with the purpose of improving the understanding of C. kroppenstedtii-like species and related diseases.

Specular highlight removal by federated generative adversarial network with attention mechanism

Specular highlight removal ensures the acquisition of high-quality images, which finds its important applications in stereo matching, text recognition and image segmentation. In order to prevent the leakage of images containing personal information, such as identification card (ID) photos, clients often train specular highlight removal models using local data resulting in a lack of precision and generalization of the trained model. To address this challenge, this paper introduces a new method to remove highlight in images using federated learning (FL) and attention generative adversarial network (AttGAN). Specifically, the former builds a global model in the central server and updates the global model by aggregating model parameters of clients. This process does not involve the transmission of image data, which enhances the privacy of clients; the later combining attention mechanisms and generative adversarial network aims to improve the quality of highlight removal by focusing on key image regions, resulting in more realistic and visually pleasing results. The proposed FL-AttGAN method is numerically evaluated, using SD1, SD2 amd RD datasets. The results show that the proposed FL-AttGAN outperforms existent methods.

Utilization of MALDI-TOF MS in the etiological diagnosis of deep-seated anaerobic bacterial infections

PurposeDeep-seated abscesses can be caused by a wide array of bacteria in various anatomical sites, the precise identification of which is crucial for implementing organism-specific treatments which can reduce morbidity and mortality. MALDI-TOF MS is a powerful proteomic method for the swift and accurate identification of anaerobic organisms. The aim of this study was to investigate deep-seated infections by MALDI-TOF MS (in comparison to VITEK®2 ANC ID card and phenotypic biochemical tests) and to determine the susceptibility pattern of identified microorganisms. Materials and methodsA total of 104 samples from patients suspected of deep-seated infections were aseptically collected and subjected to microscopy, aerobic/anaerobic cultures and subsequent identification via MALDI-TOF MS followed by antimicrobial susceptibility testing. Anaerobic bacteria were also identified using the VITEK-2 system and phenotypic biochemical tests. ResultsOut of the 104 samples tested, 41.3 % (43/104) showed positive results, predominantly in pus specimens (88 %). Mixed infections were found in 21 % of the positive cases. Of the 52 organisms identified from positive specimens, 19.2 % (10/52) were obligate anaerobes, with Bacteroides fragilis group being the most prevalent, followed by both Clostridium perfringens and Clostridium sporogenes respectively. Escherichia coli was observed to be the most common facultative anaerobic isolate. All obligate anaerobes were successfully identified to the species level via MALDI-TOF MS. In contrast, the VITEK®2 ANC ID card identified only 40 % (4/10) anaerobic bacteria to the species level. All obligate anaerobic organisms showed 100 % susceptibility to metronidazole, vancomycin and ertapenem. 25 % of the Bacteroides spp. and 50 % of Clostridium perfringens isolates were found to be resistant to clindamycin. ConclusionMALDI-TOF MS proves as a beneficial diagnostic tool for bacterial identification, eliminating the labour-intensive and time consuming conventional microbiological methods. Its accuracy of bacterial detection further helps in combating antibiotic resistance and improving patient outcomes in deep-seated infections.

Comprehensive feedback on user experiences with brain injury identification cards.

Brain injuries are often "invisible" injuries that can have lifelong consequences including changes in identity, functional independence, relationships, and reduced participation in daily activities. Survivors of brain injury experience stigma and challenges related to the misattribution of symptoms to other causes that are significant barriers to recovery and adjustment. Changes in policy and other large-scale interventions are cited as an underexplored, yet critical path to reducing the impact of brain injury. The present study sought to comprehensively characterize the impact of one such initiative-Brain Injury Identification Cards-among survivors to further refine the resource. In this cross-sectional qualitative focus group study, we recruited 16 individuals with a history of brain injury via email listservs of individuals who registered for a Brain Injury Identification Card. We used rapid data analysis with a hybrid of deductive and inductive analytic strategies to identify themes within a priori domains. We extracted themes within four domains: (a) process and reasons for obtaining cards; (b) overall impressions of the cards; (c) uses of the cards; and (d) feedback and proposed changes. Participants described the process of obtaining cards as straightforward and shared wide-ranging benefits across domains, including improving survivors' sense of safety, self-advocacy, and ability to participate in daily activities. Findings highlight the utility of Brain Injury Identification Cards for improving community understanding of brain injury symptoms and how injury-related challenges may manifest in daily life.

A Well-Tested Pump Card Classification and Identification Algorithm Based on Time Series Analysis Techniques

Abstract To accurately identify the operational conditions of oil pumping wells, promptly monitor the working status of oil wells, expedite responses to sudden pumping well accidents, and ensure orderly production at the oil extraction site, this paper introduces a time segment-based oil pumping well condition identification algorithm. This method no longer relies on drawn dynamometer cards for condition identification. Instead, it solely utilizes sensor-provided polished rod displacement and load time series, aligning more closely with the data’s intrinsic nature. The algorithm is sufficiently lightweight, highly responsive, and does not require GPU resources, making it suitable for edge deployment. Furthermore, this approach provides evidence of the time continuity and numerical continuity of time series data. Compared to traditional identification methods, this approach maintains a high level of accuracy, offers a streamlined model, and is interpretable, presenting a novel perspective for oil pumping well condition identification.

Microbiology of Actinomyces Species Isolated From Patients With Invasive Disease and Contaminated Samples in a Comprehensive Cancer Center.

Actinomyces are mucous membrane commensals that infrequently cause invasive disease. Our goal was to define Actinomyces species prevalence, the predominant disease site and risk factors for actinomycosis. We retrospectively reviewed patients with growth of Actinomyces species from cultures in a single-cancer center from July 2007 to June 2020. Proven invasive actinomycosis was defined as the presence of compatible clinical syndrome and radiographic findings with histopathological confirmation or culture from a normally sterile site. Probable invasive actinomycosis was defined based on the same criteria but without histologic confirmation. Contaminants were defined as culture growth in the absence of clinical or radiological findings consistent with disease. Speciation of Actinomyces was performed by the bioMerieux VITEK 2 anaerobic and coryneform identification card. Of 235 patients, 179 (76.2%) had malignancy. Among 90 (38.3%) patients with invasive actinomycosis, A odontolyticus was isolated in 32 (35.6%), followed by A meyeri in 20 (22.2%), and A naeslundii in 17 (18.9%). Among 145 (61.7%) colonized patients, A odontolyticus was isolated in 67 (46.2%), followed by A naeslundii in 27 (18.6%). Abdominopelvic infection was the most common site for invasive actinomycosis documented in 54 patients (60.0%) followed by orocervicofacial in 14 (15.6%) and thoracic in 10 (11.1%). A odontolyticus, A meyeri, and A naeslundi were the most frequently isolated species causing invasive actinomycosis, and A odontolyticus and A nauslendii among colonizers. Abdominopelvic represented the most frequent site for invasive disease. Further studies are needed to investigate the epidemiology of Actinomyces species in this population.

Efficient Strategy to Discover DNA Aptamers Against Low Abundance Cell Surface Proteins in Scarce Samples.

Molecular recognition probes targeting cell surface proteins such as aptamers play crucial roles in precise diagnostics and therapy. However, the selection of aptamers against low-abundance proteins in situ on the cell surface, especially in scarce samples, remains an unmet challenge. In this study, we present a single-round, single-cell aptamer selection method by employing a digital DNA sequencing strategy, termed DiDS selection, to address this dilemma. This approach incorporates a molecular identification card for each DNA template, thereby mitigating biases introduced by multiple PCR amplifications and ensuring the accurate identification of aptamer candidates. Through DiDS selection, we successfully obtained a series of high-quality aptamers against cell lines, clinical specimens, and neurons. Subsequent analyses for target identification revealed that aptamers derived from DiDS selection exhibit recognition capabilities for proteins with varying abundance levels. In contrast, multiple rounds of selection resulted in the enrichment of only one aptamer targeting a high-abundance target. Moreover, the comprehensive profiling of cell surfaces at the single-cell level, utilizing an enriched aptamer pool, revealed unique molecular patterns for each cell line. This streamlined approach holds promise for the rapid generation of specific recognition molecules targeting cell surface proteins across a broad range of expression levels and expands its applications in cell profiling, specific probe identification, biomarker discovery, etc.

Vulvovaginal candidiasis clinical signs, and distribution of Candida species

Background: Vulvovaginal candidiasis is a global issue of concern due to its association with economic costs, sexually transmitted infections, and ascending genital tract infection. The aim of this study was to determine clinical signs and species distribution of Candida species causing vulvovaginal candidiasis. Methods: A cross-sectional study was conducted from December to June 2021-2024 among 400 women attending Obstetrics and Gynecology outpatient clinics in Sana'a City. The study involved collecting vaginal swabs from each participant and analyzing them in a microbiology laboratory. The swabs were used to identify yeast cells, fungal culturing, and germ tube formation tests. The study also used the VITEK II system to confirm species identification, with the VITEK® 2 YST ID identification card being used to identify Candida species. Results: A study of 400 women found that 91.8% were infected with Candida albicans, while 8.2% were infected with other non-Candida albicans. The majority were aged 26-35, with secondary education being the most common. Most were married, with 1-3 pregnancies. The most common sign distribution was vaginal discharge with a 99.5% prevalence. Dysuria was the lowest, with a 65.0% prevalence. Candida species were most frequently isolated, with Candida albicans being the most common. Candida tropicalis was found in 1 out of 6 women, while Candida dubliniensis, Candida famata, Candida glabrata, and Candida lusitaniae were found in 1 out of 6 women. Conclusions: The high prevalence rate of vulvovaginal candidiasis and observation of a low prevalence rate of nonalbicans Candida species in the present study substantiate the importance of conducting continuous epidemiological surveys to measure changes in species distribution from C. albicans to non-albicans Candida species in Yemen.

A designated private set based trapdoor authentication scheme for privacy preserving trust management in decentralized systems

Authentication is crucial for network system security, relying on methods such as passwords, ID cards, biometrics, and behavioral characteristics. The conventional centralized authentication may lead to potential performance bottlenecks and privacy risks such as key exposure, single point of failure. Decentralized authentication systems using cryptographic techniques aim to address these issues but often tradeoff between flexibility and communication efficiency. In this paper we propose a new cryptographic concept called designated private set-based trapdoor authentication (DPSBTA) for flexible and efficient trust management in decentralized systems. DPSBTA eliminates the need for a trusted authority, with users’ access privileges defined by their private sets. During the authentication process, each server can designate an element set and only if a user holds adequate elements which are contained in the designated set can he obtains a credential from the server. The key features of DPSBTA include: decentralized trapdoor authentication management, without a trusted authority, conducted in a double threshold manner; privacy preservation, as servers do not know users’ element holdings or credential generation; round-optimal communication, with only two rounds of interaction between users and servers. We present the generic construction, security models, and concrete algorithms with correctness proof. The theoretical proof and the performance evaluations demonstrate the tangible security and high efficacy of the proposed DPSBTA.
