Puerarin Alleviates Experimental Autoimmune Thyroiditis by Regulating Macrophages.

Hashimoto's thyroiditis (HT) is the most common organ-specific autoimmune disease, predominantly affecting women. Although the pathogenesis of HT is incompletely understood, some studies have found that macrophage polarization plays a role. Puerarin is a soy isoflavone compound that has anti-inflammatory and immunomodulatory effects and regulates macrophage immune activity. This study aimed to verify the therapeutic effect of puerarin on HT and explored its regulatory effect on macrophage polarization imbalance in HT. Through bioinformatics analysis and molecular biology methods, it was found that macrophages increased significantly in HT patients and model mice. Immunological staining showed that puerarin intervention could reduce tissue inflammatory cell infiltration. Molecular biological examination displayed that puerarin could inhibit local and systemic inflammation levels, and the expression of marker thyroglobulin and thyroid peroxidase Abs. In vivo experimental results indicated that puerarin regulated macrophage polarity and reduced inflammatory damage, possibly by inhibiting the pyroptosis signaling pathway. In vivo macrophage clearance experiments demonstrated that puerarin relied on macrophages to exert its mechanism of action in treating HT. The results of this study indicate that macrophages are important mediators in the development of HT, and puerarin can regulate macrophage polarity and inflammatory status to provide thyroid tissue protection, which provides a new idea for the treatment of HT.

PET imaging of Aspergillus infection using Zirconium-89 labeled anti-ß-glucan antibody fragments.

PURPOSE: Invasive fungal diseases, such as pulmonary aspergillosis, are common life-threatening infections in immunocompromised patients and effective treatment is often hampered by delays in timely and specific diagnosis. Fungal-specific molecular imaging ligands can provide non-invasive readouts of deep-seated fungal pathologies. In this study, the utility of antibodies and antibody fragments (Fab) targeting ß-glucans in the fungal cell wall to detect Aspergillus infections was evaluated both in vitro and in preclinical mouse models. METHODS: The binding characteristics of two commercially available ß-glucan antibody clones and their respective antigen-binding Fabs were tested using biolayer interferometry (BLI) assays and immunofluorescence staining. In vivo binding of the Zirconium-89 labeled antibodies/Fabs to fungal pathogens was then evaluated using PET/CT imaging in mouse models of fungal infection, bacterial infection and sterile inflammation. RESULTS: One of the evaluated antibodies (HA-ßG-Ab) and its Fab (HA-ßG-Fab) bound to ß-glucans with high affinity (KD = 0.056 & 21.5 nM respectively). Binding to the fungal cell wall was validated by immunofluorescence staining and in vitro binding assays. ImmunoPET imaging with intact antibodies however showed slow clearance and high background signal as well as nonspecific accumulation in sites of infection/inflammation. Conversely, specific binding of [89Zr]Zr-DFO-HA-ßG-Fab to sites of fungal infection was observed when compared to the isotype control Fab and was significantly higher in fungal infection than in bacterial infection or sterile inflammation. CONCLUSIONS: [89Zr]Zr-DFO-HA-ßG-Fab can be used to detect fungal infections in vivo. Targeting distinct components of the fungal cell wall is a viable approach to developing fungal-specific PET tracers.

Ancestral Information Analysis of Chinese Korean Ethnic Group via a Novel Multiplex DIP System.

Deletion/insertion polymorphism (DIP) is one of the more promising genetic markers in the field of forensic genetics for personal identification and biogeographic ancestry inference. In this research, we used an in-house developed ancestry-informative marker-DIP system, including 56 autosomal diallelic DIPs, three Y-chromosomal DIPs, and an Amelogenin gene, to analyze the genetic polymorphism and ancestral composition of the Chinese Korean group, as well as to explore its genetic relationships with the 26 reference populations. The results showed that this novel panel exhibited high genetic polymorphism in the studied Korean group and could be effectively applied for forensic individual identification in the Korean group. In addition, the results of multiple population genetic analyses indicated that the ancestral component of the Korean group was dominated by northern East Asia. Moreover, the Korean group was more closely related to the East Asian populations, especially to the Japanese population in Tokyo. This study enriched the genetic data of the Korean ethnic group in China and provided information on the ancestry of the Korean group from the perspective of population genetics.

Application of microfluidic technologies in forensic analysis.

The application of microfluidic technology in forensic medicine has steadily expanded over the last two decades due to the favorable features of low cost, rapidity, high throughput, user-friendliness, contamination-free, and minimum sample and reagent consumption. In this context, bibliometric methods were adopted to visualize the literature information contained in the Science Citation Index Expanded from 1989 to 2022, focusing on the co-occurrence analysis of forensic and microfluidic topics. A deep interpretation of the literature was conducted based on co-occurrence results, in which microfluidic technologies and their applications in forensic medicine, particularly forensic genetics, were elaborated. The purpose of this review is to provide an impartial evaluation of the utilization of microfluidic technology in forensic medicine. Additionally, the challenges and future trends of implementing microfluidic technology in forensic genetics are also addressed.

Integrated Network Pharmacology and Molecular Docking to Elucidate the Efficacy and Potential Mechanisms of Tea Ingredients in Sepsis Treatment.

Sepsis, a critical health condition induced by an overactive innate immune response and reactive oxygen species (ROS)-driven host damage through apoptosis and ferroptosis, continues to pose a significant mortality risk. Despite accumulating evidence of the potential therapeutic properties of tea ingredients, their specific anti-sepsis potential remains inadequately explored. This study comprehensively investigates the targeted genes of tea ingredients, notably epigallocatechin 3-gallate (EGCG), and their correlation with sepsis signature genes. Our findings elucidate that tea ingredients, especially EGCG, exhibit substantial potential in mitigating inflammation and sepsis-induced damage. Through the inhibition of the MAPK cascade and macrophage activation and by impeding the transcriptional activity of RELA (transcription factor p65) in sepsis, EGCG demonstrates significant anti-sepsis efficacy. Molecular docking analysis further underpins this by revealing the close proximity of EGCG and (-)-catechin gallate binding sites to that of RELA on DNA. Subsequent in vitro assays illuminated EGCG's instrumental role in modulating macrophage M2 polarization, balancing M1 and M2 differentiation of bone marrow-derived macrophages (BMDMs), curtailing inflammatory factor secretion, and inhibiting ROS production. Moreover, EGCG effectively suppresses the expression of ferroptosis/apoptosis markers in LPS-induced macrophages during their early stages. Our study advances our understanding of sepsis prevention and treatment strategies, suggesting that tea ingredients such as EGCG could play a pivotal role in developing future sepsis therapies due to their protective effects.

Circadian nuclear receptor Rev-erbα is expressed by platelets and potentiates platelet activation and thrombus formation.

AIMS: Adverse cardiovascular events have day/night patterns with peaks in the morning, potentially related to endogenous circadian clock control of platelet activation. Circadian nuclear receptor Rev-erbα is an essential and negative component of the circadian clock. To date, the expression profile and biological function of Rev-erbα in platelets have never been reported. METHODS AND RESULTS: Here, we report the presence and functions of circadian nuclear receptor Rev-erbα in human and mouse platelets. Both human and mouse platelet Rev-erbα showed a circadian rhythm that positively correlated with platelet aggregation. Global Rev-erbα knockout and platelet-specific Rev-erbα knockout mice exhibited defective in haemostasis as assessed by prolonged tail-bleeding times. Rev-erbα deletion also reduced ferric chloride-induced carotid arterial occlusive thrombosis, prevented collagen/epinephrine-induced pulmonary thromboembolism, and protected against microvascular microthrombi obstruction and infarct expansion in an acute myocardial infarction model. In vitro thrombus formation assessed by CD41-labelled platelet fluorescence intensity was significantly reduced in Rev-erbα knockout mouse blood. Platelets from Rev-erbα knockout mice exhibited impaired agonist-induced aggregation responses, integrin αIIbß3 activation, and α-granule release. Consistently, pharmacological inhibition of Rev-erbα by specific antagonists decreased platelet activation markers in both mouse and human platelets. Mechanistically, mass spectrometry and co-immunoprecipitation analyses revealed that Rev-erbα potentiated platelet activation via oligophrenin-1-mediated RhoA/ERM (ezrin/radixin/moesin) pathway. CONCLUSION: We provided the first evidence that circadian protein Rev-erbα is functionally expressed in platelets and potentiates platelet activation and thrombus formation. Rev-erbα may serve as a novel therapeutic target for managing thrombosis-based cardiovascular disease.

Synthesis and Evaluation of Fluorine-18-Labeled L-Rhamnose Derivatives.

The use of radiolabeled glucose for PET imaging resulted in the most commonly used tracer in the clinic, 2-deoxy-2-[18F]fluoroglucose (FDG). More recently, other radiolabeled sugars have been reported for various applications, including imaging tumors and infections. Therefore, in this study, we developed a series of fluorine-18-labeled L-rhamnose derivatives as potential PET tracers of various fungal and bacterial strains. Acetyl-protected triflate precursors of rhamnose were prepared and radiolabeled with fluorine-18 followed by hydrolysis to produce L-deoxy [18F]fluororhamnose. The overall radiochemical yield was 7-27% in a 90 min synthesis time with a radiochemical purity of 95%. In vivo biodistribution of the ligands using PET imaging showed that 2-deoxy-2-[18F]fluoro-L-rhamnose is stable for at least up to 60 min in mice and eliminated via renal clearance. The tracer also exhibited minimal tissue or skeletal uptake in healthy mice resulting in a low background signal.

3'-[18F]fluoro-3'-deoxythymidine ([18F]FLT) Positron Emission Tomography as an In Vivo Biomarker of inhibition of CDK 4/6-Rb pathway by Palbociclib in a patient derived bladder tumor.

BACKGROUND: Several new generation CDK4/6 inhibitors have been developed and approved for breast cancer therapy in combination with endocrine therapeutics. Application of these inhibitors either alone or in combination in other solid tumors has been proposed, but no imaging biomarkers of response have been reported in non-breast cancer animal models. The purpose of this study was to evaluate 3'-[18F]fluoro-3'-deoxythymidine ([18F]FLT) Positron Emission Tomography (PET) as in vivo biomarker of response to palbociclib in a non-breast cancer model. METHODS: Twenty-four NSG mice bearing patient derived xenografts (PDX) of a well-characterized bladder tumor were randomized into 4 treatment groups: vehicle (n = 6); palbociclib (n = 6); temozolomide (n = 6); and palbociclib plus temozolomide (n = 6) and treated with two cycles of therapy or vehicle. Tumor uptake of [18F]FLT was determined by micro-PET/CT at baseline, 3 days, and 9 days post initiation of therapy. Following the second cycle of therapy, the mice were maintained until their tumors reached a size requiring humane termination. RESULTS: [18F]FLT uptake decreased significantly in the palbociclib and combination arms (p = 0.0423 and 0.0106 respectively at day 3 and 0.0012 and 0.0031 at day 9) with stable tumor volume. In the temozolomide arm [18F]FLT uptake increased with day 9 uptake significantly different than baseline (p = 0.0418) and progressive tumor growth was observed during the treatment phase. All groups exhibited progressive disease after day 22, 10 days following cessation of therapy. CONCLUSION: Significant decreases in [18F]FLT uptake as early as three days post initiation of therapy with palbociclib, alone or in combination with temozolomide, in this bladder cancer model correlates with an absence of tumor growth during therapy that persists until day 18 for the palbociclib group and day 22 for the combination group (6 days and 10 days) following cessation of therapy. These results support early modulation of [18F]FLT as an in vivo biomarker predictive of palbociclib therapy response in a non-breast cancer model.

Network Traffic Prediction Incorporating Prior Knowledge for an Intelligent Network.

Network traffic prediction is an important tool for the management and control of IoT, and timely and accurate traffic prediction models play a crucial role in improving the IoT service quality. The degree of burstiness in intelligent network traffic is high, which creates problems for prediction. To address the problem faced by traditional statistical models, which cannot effectively extract traffic features when dealing with inadequate sample data, in addition to the poor interpretability of deep models, this paper proposes a prediction model (fusion prior knowledge network) that incorporates prior knowledge into the neural network training process. The model takes the self-similarity of network traffic as a priori knowledge, incorporates it into the gating mechanism of the long short-term memory neural network, and combines a one-dimensional convolutional neural network with an attention mechanism to extract the temporal features of the traffic sequence. The experiments show that the model can better recover the characteristics of the original data. Compared with the traditional prediction model, the proposed model can better describe the trend of network traffic. In addition, the model produces an interpretable prediction result with an absolute correction factor of 76.4%, which is at least 10% better than the traditional statistical model.

A case of iatrogenic intussusception in adults: a rare case report.

BACKGROUND: Intussusception has a low incidence rate in adults. Many cases in adults are caused by tumors. Intussusception results from conditions other than tumors are uncommon. This is the first case report about intussusception that occurred after removing a long intestinal tube (LT). CASE PRESENTATION: A 69-year-old female complained of "recurrent abdominal pain with reduced flatus passage and frequency of bowel movement for 10 days" was admitted to the hospital. Plain abdominal radiography and abdominal CT upon admission showed intestinal obstruction. The patient's abdominal pain was not relieved after symptomatic treatments, which involved fluid and electrolyte replacement, LT placement, spasmolytic agents, and analgesics. Hence, surgical exploration was carried out. The patient had a good recovery postoperatively. No abdominal pain or bloating developed after food intake. The patient passed flatus and had bowel movements later. On postoperative day 9, the LT was removed. On the 10th day, the patient suddenly developed abdominal distension and acute abdominal pain. Emergency abdominal CT showed small bowel intussusception. Surgical exploration was then performed. Severe small bowel dilatation located at 1.5 m from the ligament of Treitz was found during the procedure. Intussusception at the site was observed. No color change of the intestinal wall was detected, suggesting that no necrosis was present. So, a manual reduction was done. The patient was discharged on postoperative day 6. CONCLUSIONS: This case serves as a warning that the simple action of pulling out the LT might also cause serious complications, which should be given more attention.

Joint Power and Subchannel Allocation for Distributed Storage in Cellular-D2D Underlays.

Wireless distributed storage is beneficial in the provision of reliable content storage and offloading of cellular traffic. In this paper, we consider a cellular device-to-device (D2D) underlay-based wireless distributed storage system, in which the minimum storage regenerating (MSR) coding combined with the partial downloading scheme is employed. To alleviate burdens on insufficient cellular resources and improve spectral efficiency in densely deployed networks, multiple storage devices can simultaneously use the same uplink cellular subchannel under the non-orthogonal multiple access (NOMA) protocol. Our objective is to minimize the total transmission power for content reconstruction, while guaranteeing the signal-to-interference-plus-noise ratio (SINR) constraints for cellular users by jointly optimizing power and subchannel allocation. To tackle the non-convex combinational program, we decouple the original problem into two subproblems and propose two low-complexity algorithms to efficiently solve them, followed by a joint optimization, implemented by alternately updating the solutions to each subproblem. The numerical results illustrate that our proposed algorithms are capable of performing an exhaustive search with lower computation complexity, and the NOMA-enhanced scheme provides more transmission opportunities for neighbor storage devices, thus significantly reducing the total power consumption.

The therapeutic role of baicalein in combating experimental periodontitis with diabetes via Nrf2 antioxidant signaling pathway.

BACKGROUND AND OBJECTIVE: Oxidative stress has been suggested as an important pathogenic factor contributing to chronic periodontitis with diabetes mellitus (CPDM). Previous studies have revealed the potential therapeutic properties of baicalein (BCI) in oxidative stress-related diseases; however, the antioxidant effects of BCI on therapy for individual with CPDM remain largely unexplored. Nuclear factor erythroid 2-related factor 2 (Nrf2) plays a critical role in cellular defence against oxidative stress. In this study, we aim to determine whether BCI prevents diabetes-related periodontal tissue destruction by regulating Nrf2 signaling pathway. MATERIAL AND METHODS: Human gingival epithelial cells (hGECs) were challenged with high glucose (HG, 25 mmol/L) and/or lipopolysaccharide (LPS, 20 µg/mL). Reactive oxygen species (ROS) were detected by fluorescence-activated cell sorting. The changes of antioxidant-related genes, including Nrf2, catalase (Cat), glutamate-cysteine ligase catalytic subunit (Gclc), superoxide dismutase 1 (Sod1), and superoxide dismutase 2 (Sod2), were quantified by real-time PCR. The localization of phospho-Nrf2 (pNrf2, S40) in the nucleus was detected by immunofluorescence staining and laser scanning confocal microscope (LSCM). PNrf2 and total form of Nrf2 were determined using western blot. The above indicators together with mitochondrial membrane potential (MMP) were further investigated in hGECs pre-treated with different concentrations of BCI (0.01, 0.1, or 0.5 µg/mL) before stimulated with HG plus LPS (GP). Finally, the role of BCI in activating Nrf2 signaling pathway and relieving the alveolar bone absorption was examined in the CPDM model of Sprague Dawley rats. CPDM rats were oral gavaged with BCI (50, 100, or 200 mg/kg daily). The pNrf2 was detected by immunohistochemistry, and the alveolar bone absorption was examined by microcomputed tomography. RESULTS: Our results showed that ROS were significantly increased in both groups of HG and LPS, with the strongest generation in the GP group. In terms of ROS-related gene expression, we found that the mRNA levels of Nrf2, Cat, Gclc, Sod1, and Sod2 were significantly decreased in HG and LPS groups. In consistent with the strongest induction of ROS in GP group, the gene expression in GP group was further decreased as compared to those of HG and LPS groups. Also, the expression of pNrf2 exhibited the same trend with the expression of those antioxidant genes. However, the generation of ROS and the loss of mitochondrial membrane potential induced by GP were abolished by pre-treatment with different concentrations of BCI (0.01, 0.1, or 0.5 µg/mL). Interestingly, we observed that BCI promoted the nucleus translocation of pNrf2, as well as the gene expression levels of pNrf2 and its target genes (Cat, Gclc, Sod1, and Sod2). Finally, in the CPDM animal model, we found that BCI (at concentrations: 50, 100, and 200 mg/kg) markedly increased the number of pNrf2-positive cells in periodontal tissue and mitigated the alveolar bone loss. CONCLUSIONS: Our data revealed a potential role for clinic application of BCI under CPDM conditions, suggesting a new therapeutic drug for CPDM patients.

In vivo biological safety evaluation of an iron-based bioresorbable drug-eluting stent.

Bioresorbable stents (BRS) are investigated and designed to revascularize occluded arteries. The iron-based bioresorbable stent is a promising device in interventional therapies, although it's corrosion and bioresorption rate remain challenging. In this work, we introduced a novel nitrided iron coronary stent (IBS) with enhanced degradation rate compared with pure iron stent. To evaluate the biosafety of this device, a sub-chronic systemic toxicity study was conducted and a stainless steel stent (Supporter™) served as a control. Here, the bioresorbable stent was first evaluated in rat abdominal aortic implantation model. When subjected to exaggerated exposure dose, no clinical signs of toxicity or mortality were observed in either, the IBS group or the control group. Histopathological examinations showed the corrosion particles of iron were encapsulated by fibrocytes and engulfed by macrophages, indicating that the degradation of iron was in the early stage. Our results demonstrated that the nitrided iron stent did not induce systemic toxicity under the experimental conditions.

[Study of No Observed Adverse Effect Level of Nickel and Its Preliminary Evaluation Biocompatibility].

The purpose of this study was to investigate the NOAEL of the nickel ion and provide with basic data for the biological evaluation of those medical devices containing nickel. Five groups SD rats were repeatedly exposed during 14 d respectively to nickel at first stage doses of 4.9, 3.7, 2.5 mg/(kg.d), and the second stage doses of 1.2, 0.25 mg/(kg.d) by the intravenous route. The results showed that the NOAEL of nickel ion is 0.25 mg/(kg.d) for SD rats, and the result was verified by subchronic systemic toxicity test of nickel alloy. The threshold of toxicological concern (TTC) of nickel is 150 µg/d (based on application of 100-fold uncertainty factor and a body weight of 60 kg)deduced by these data.

Internal validation study of a newly developed 24-plex Y-STRs genotyping system for forensic application.

Prior to implementing a new kit into application, developmental validation should be conducted to demonstrate the robustness and applicability of the kit. In this study, 24 Y-STR loci from the AGCU Y SUPP STR kit were tested including 11 loci overlapping with other commercial kits (DYS385a/b, DYS635, DYS533, DYS481, DYS549, DYS460, DYS527a/b, DYS522, and DYS444) and 13 new loci (DYS531, DYS630, DYS622, DYS552, DYS510, DYS459a/b, DYS446, DYS443, DYS587, Y-GATA-A10, DYS520, and DYS557). Developmental validation including PCR-related studies, sensitivity, stability, and species specificity studies were conducted. The performance of the kit in genotyping case-type samples was also estimated. The results indicated that the kit is robust, accurate and sensitive and is able to detect male samples without being affected by female samples or other species. Population data were obtained with this kit in Chinese Xibe group as well. Totally 139 different haplotypes were obtained from 167 male samples and demonstrated that this typing system is relatively discriminative.

The association between albumin-dNLR score and disease activity in patients with rheumatoid arthritis.

BACKGROUND: Recently, clinical studies have described an association between albumin and the derived neutrophil to lymphocyte ratio (dNLR) with several diseases. This study was aimed to investigate the albumin-dNLR (ALB-dNLR) score in rheumatoid arthritis (RA) patients and assess its relationship with clinical and laboratory parameters of RA. METHODS: We retrospectively enrolled 127 RA patients, 155 osteoarthritis (OA) patients, and 155 healthy controls. The ALB-dNLR score was based on serum albumin level, neutrophil count, and white cell count. The Spearman's rank test was used to measure the correlations between ALB-dNLR score and disease activity as well as laboratory indexes. RESULTS: The ALB-dNLR score was significantly higher in RA patients than in OA patients (P < 0.001) and in healthy controls (P < 0.001). The proportion of higher ALB-dNLR score has been raised along with increased disease activity (P < 0.001). The Spearman's rank test showed that ALB-dNLR score was positively associated with DAS28 score, CRP, ESR, IgA, and platelet count. Moreover, the receiver operating characteristic (ROC) curve showed that the area under the curve (AUC) of ALB-dNLR was 0.693 (95% CI: 0.631-0.755), which was higher than that of albumin (AUC: 0.625, 95% CI: 0.559-0.692) and dNLR (AUC: 0.680, 95% CI: 0.617-0.743) alone. CONCLUSIONS: The results demonstrate that the ALB-dNLR score increased in RA patients. The ALB-dNLR score may be a useful marker to estimate the disease activity of RA patients.

Tuning the dispersion of effective surface plasmon polaritons with multilayer systems.

Recently, effective surface plasmon polaritons (ESPPs) induced by structural dispersion in bounded waveguides were theoretically demonstrated and experimentally verified. Despite the theoretical and experimental efforts, whether ESPPs can mimic real SPPs in every aspect still remains an open question. In this work, we go one step further to study the hybridization of ESPPs in multilayer systems. We consider transverse electric (TE) modes in a conventional rectangular waveguide and a parallel-plate waveguide (PPW) and derive analytically the dispersion relations and asymptotic frequencies of the corresponding ESPPs modes in sandwiched structures consisting of alternating dielectrics of different permittivities. Our results show that the ESPPs can be categorized into odd and even parities (owing to the 'plasmon' hybridization) in a similar way as natural SPPs supported by the insulator/metal/insulator (IMI) and metal/insulator/metal (MIM) heterostructures in the optical regime. The similarities and differences between ESSPs and their optical counterparts are also discussed in details, which may provide valuable guidance for future application of ESPPs at the microwave and terahertz frequencies.

Comparison of a Newly Developed HPV Genotyping Assay (Mojin HPV Kit) with Cobas 4800 HPV Test for Detection of High-Risk HPV in Specimens Collected in SurePath Solution.

BACKGROUND: Human papillomavirus (HPV) detection based on cervical cytology specimens is useful for cervical cancer screening. The aim of this study was to compare Mojin HPV kit (a newly developed HPV genotyping assay) with the Cobas 4800 HPV test in detecting high-risk (HR) HPV. METHODS: A total of 347 cervical exfoliated cell specimens were tested using the Mojin HPV kit and Cobas 4800 HPV test. When the results from the two tests were inconsistent, gene sequencing was performed for correction. RESULTS: For HR-HPV, the results of the two assays agreed by 96.3% [Kappa = 0.911; 95% confidence interval (CI): 0.863 - 0.958)]. The positive and negative coincidence rates between the two tests were 96.0% (95% CI: 92.7% - 98.0%) and 97.0% (95% CI: 91.5% - 99.4%), respectively. Of the 13 samples with discordant results, 3 samples were false positive and 10 samples were true negative for Mojin HPV test, according to the identification by sequencing. For HPV16 genotyping, the total coincidence rate between the 2 tests was 100% (Kappa = 1.000), and 99.7% (Kappa = 0.973; 95% CI: 0.905 - 1.000) for HPV18. CONCLUSIONS: Mojin HPV kit may be as effective as Cobas 4800 HPV assay in detecting the total HR-HPV, especially HPV16 or HPV18.
