Exome Sequencing Starting from Single Cells.

Single-cell genomic analysis enables researchers to gain novel insights across diverse research areas, including developmental biology, tumor heterogeneity, and disease pathogenesis. Conducting single-cell genomic analysis using next-generation sequencing (NGS) methods has traditionally been challenging as the amount of genomic DNA present in a single cell is limited. Advancements in multiple displacement amplification (MDA) technologies allow the unbiased amplification of limited quantities of DNA under conditions that maintain its integrity. This method of amplification results in high yield and facilitates the generation of high-complexity NGS libraries that ensure the highest coverage to effectively allow variant calling. With the introduction of new sequencing platforms and chemistry, whole genome sequencing became a more cost-effective application, but enrichment of specific regions of interest further reduces the amount of required sequencing output and associated costs. There are two enrichment methods, polymerase chain reaction (PCR)-based and hybrid-capture-based methods. PCR-based methods are very flexible and highly effective but focus on specific loci, typically known to be associated with disease. Inherited diseases of unknown genetic origin require a more comprehensive approach to capture the genetic variation that is not yet associated with a specific disease. Hybrid capture enrichment methods require considerable amounts of DNA such that exome enrichment from single cells is only possible after preamplification of this limited material. This article describes the complete workflow from single cells and small quantities of DNA to exome-NGS libraries for Illumina sequencing instruments and includes the following protocols: © 2024 The Author(s).

Prospective randomized study comparing mesh displacement in enhanced-view totally extraperitoneal versus totally extraperitoneal laparoscopic inguinal hernia repair without mesh fixation.

PURPOSE: In laparoscopic inguinal hernia repair, it is thought that the mesh can be displaced more in the enhanced-view totally extraperitoneal (eTEP) technique. The aim of this study was to compare eTEP and totally extraperitoneal (TEP) techniques without mesh fixation in terms of mesh displacement and hernia recurrence. METHODS: Between December 2022 and April 2023, 60 consecutive patients with unilateral inguinal hernia were randomized into two groups; eTEP group (n = 30) and TEP group (n = 30). There was without mesh fixation in both groups. Study was registered at http://Clinicaltrials.gov (NCT06070142). The mesh was marked with three radiopaque clips. Pelvic radiographs were performed to evaluate the displacement of the mesh. The primary outcome of this study was mesh displacement. In addition, this is the first study in the literature to compare eTEP and TEP techniques in terms of mesh displacement without fixation in laparoscopic inguinal hernia. RESULTS: There was no significant difference between the groups in terms of mesh displacement, recurrence, postoperative VAS scores, length of hospital stay, hematoma, and seroma formation. The operation time was higher in the eTEP group and was statistically significant. CONCLUSION: Without mesh fixation, the eTEP technique does not increase the risk of mesh displacement and recurrence. The eTEP technique can be safely applied without mesh fixation in laparoscopic inguinal hernia repairs. TRIAL REGISTRATION: ClinicalTrials number: NCT06070142.

Sprain energy consequences for damage localization and fracture mechanics.

The 2023 smooth Lagrangian Crack-Band Model (slCBM), inspired by the 2020 invention of the gap test, prevented spurious damage localization during fracture growth by introducing the second gradient of the displacement field vector, named the "sprain," as the localization limiter. The key idea was that, in the finite element implementation, the displacement vector and its gradient should be treated as independent fields with the lowest ([Formula: see text]) continuity, constrained by a second-order Lagrange multiplier tensor. Coupled with a realistic constitutive law for triaxial softening damage, such as microplane model M7, the known limitations of the classical Crack Band Model were eliminated. Here, we show that the slCBM closely reproduces the size effect revealed by the gap test at various crack-parallel stresses. To describe it, we present an approximate corrective formula, although a strong loading-path dependence limits its applicability. Except for the rare case of zero crack-parallel stresses, the fracture predictions of the line crack models (linear elastic fracture mechanics, phase-field, extended finite element method (XFEM), cohesive crack models) can be as much as 100% in error. We argue that the localization limiter concept must be extended by including the resistance to material rotation gradients. We also show that, without this resistance, the existing strain-gradient damage theories may predict a wrong fracture pattern and have, for Mode II and III fractures, a load capacity error as much as 55%. Finally, we argue that the crack-parallel stress effect must occur in all materials, ranging from concrete to atomistically sharp cracks in crystals.

Wearing the mandibular advancement orthosis and dental movements: Contribution of a digital monitoring protocol.

OBJECTIVES: Oral appliance (OA) has been increasingly used for the treatment of obstructive sleep apnoea hypopnea syndrome (OSAHS). OAs work by propelling the mandible, increasing the upper airway calibre and reducing collapsibility. While they have shown efficacy in reducing OSAHS, long-term use can lead to adverse effects, such as dental displacement. The present study focuses on the impact on dental displacements of the NARVAL® computer-aided design and manufacturing OA from the ResMed laboratory. MATERIALS AND METHODS: The study included 39 patients aged 18 or older who were treated for OSAHS using OAs initiated between 2019 and 2021 and had initial digital dental impressions. A new digital print was taken for each patient using the TRIOS 4 Wireless intra-oral scanner from 3SHAPE. Dental displacement was measured using a 3D system's GEOMAGIC design X 3D reverse engineering software. The study analysed different blocks of teeth in both the maxillary and mandibular arches. Statistical analysis was conducted to determine the significance of dental displacements. RESULTS: Patients had been wearing the OA for an average of 2.5 years. The study found dental displacements in both the maxillary and mandibular arches. However, these displacements were not statistically significant. Qualitative analysis revealed palatoversion and vestibuloversion, while quantitative analysis showed minor dental displacements. CONCLUSION: This study on patients wearing the NARVAL® OA for an average of 2.5 years found dental displacements in both the maxillary and mandibular arches. However, these displacements were not statistically significant. The results suggest that the OA, designed using a complete digital workflow, did not significantly impact dental positions. To confirm the impact, further investigations with larger sample sizes, an exclusively digital protocol and a control group are required.

The Local Rhombus-Shaped Flap-An Easy and Reliable Technique for Oncoplastic Breast Cancer Surgery and Defect Closure in Breast and Axilla.

Primarily, breast-conserving therapy is an oncological intervention, but eventually it is judged by its cosmetic result. Remaining cavities from tumor resection can promote seromas, delay healing and cause lasting discomfort. Additionally, volume loss, dislocation of nipple/areola and fat necrosis lead to (cosmetically) unfavorable results, aggravated by radiotherapy. Oncoplastic surgery can reduce these sequelae. A local flap that has rarely been used in breast cancer surgery is the Limberg rhombic flap. The tumor defect is planned as a rhombus. The sides of the rhombus are of equal length and ideally have an angle of 60° and 120°. The flap that closes the defect is planned as an extension of equal length of the short diagonal. The second incision of the flap is placed according to the defect angle of 60°, running parallel to the defect at the same length. This creates a second rhombus. The flap is transposed into the defect, and the donor area is primarily closed. It is axially perfused and safe with a 1:1 length-to-width ratio. Compared to local perforator flaps, defect closure is easily managed without microsurgical skills. In the breast, the flap can be used in volume replacement and volume displacement techniques as an all-layer flap to cover defects, or it can be deepithelialized and buried. In the axilla, it can cover full-thickness defects when skin is involved. The advantages of the rhombic flap are its safety and simplicity to add volume and close defects, thus reducing the complexity of oncoplastic surgery.

Optimal configurations of an electromagnetic tracking system for 3D ultrasound imaging of pediatric hips - A phantom study.

Tracking the position and orientation of a two-dimensional (2D) ultrasound scanner to reconstruct a 3D volume is common, and its accuracy is important. In this study, a specific miniaturized electromagnetic (EM) tracking system was selected and integrated with a 2D ultrasound scanner, which was aimed to capture hip displacement in children with cerebral palsy. The objective of this study was to determine the optimum configuration, including the distance between the EM source and sensor, to provide maximum accuracy. The scanning volume was aimed to be 320 mm × 320 mm × 76 mm. The accuracy of the EM tracking was evaluated by comparing its tracking with those from a motion capture camera system. A static experiment showed that a warm-up time of 20 min was needed. The EM system provided the highest precision of 0.07 mm and 0.01° when the distance between the EM source and sensor was 0.65 m. Within the testing volume, the maximum position and rotational errors were 2.31 mm and 1.48°, respectively. The maximum error of measuring hip displacement on the 3D hip phantom study was 4 %. Based on the test results, the tested EM system was suitable for 3D ultrasound imaging of pediatric hips to assess hip displacement when optimal configuration was used.

Carotid stents reduce longitudinal movements within the vascular wall.

BACKGROUND: Longitudinal Displacement (LD) is the relative motion of the intima-media upon adventitia of the arterial wall during the cardiac cycle, probably linked to atherosclerosis. It has a direction, physiologically first backward in its main components with respect to the arterial flow. Here, LD was investigated in various disease and in presence of a unilateral carotid stent. METHODS: Carotid acquisitions were performed by ultrasound imaging on both body sides of 75 participants (150 Arteries). LD was measured in its percent quantity and direction. RESULTS: Obesity (p = 0.001) and carotid plaques (p = 0.01) were independently associated to quantity decrease of LD in the whole population. In a subgroup analysis, it was respectively 143% in healthy (n = 48 carotids), 129% (n = 34) in presence of cardiovascular risk factors, 121% (n = 20) in MACE patients, 119% (n = 24) in the carotid contralateral to a stent, 110% (n = 24) in carotids with stents. Regarding the direction of LD, in a subgroup analysis an inverted movement was identified in aged (p = 0.001) and diseased (p = 0.001) participants who also showed less quantity of LD (p = 0.001), but independently with age only (p = 0.002) in the whole population. CONCLUSIONS: This observational study suggests that LD within carotid wall layers is lower additively with ageing, cardiovascular risk factors, cardiovascular diseases, and stent. Even if stent is surely beneficial, these data might shed some light on stent restenosis, emphasising the need for interventional studies.

A Psychophysiological Investigation of Mechanisms Underlying "Feeling Fat" in Women With and Without Binge Eating.

OBJECTIVE: "Feeling fat", the somatic experience of being overweight not fully explained by objective body weight, is considered to be an eating pathology maintenance factor. The traditional clinical understanding of "feeling fat" is based on the body displacement hypothesis, which suggests that negative emotions are projected onto the body and experienced as "feeling fat" in lieu of adaptive emotion regulation. A more recent theory suggests that "feeling fat" occurs in response to thought-shape fusion (TSF), a cognitive distortion in response to the imagined consumption of perceived fattening food. The present experimental study compared the roles of these two proposed mechanisms of "feeling fat" using self-report and psychophysiological measures. METHOD: Eighty-two women (41 with binge eating, 41 control participants) self-reported "feeling fat" and had their heart rate variability (HRV), a physiological index of emotion regulation, measured before and after imagined inductions. Participants imagined either a personalized negative affective experience or consuming a preferred, so-called 'fattening' food. RESULTS: The TSF induction increased self-reports of "feeling fat" among participants with binge eating but not among control women. The negative affect induction did not increase self-reported "feeling fat" in either group. HRV did not significantly change in response to either induction for either group. DISCUSSION: TSF may be a more potent precursor to "feeling fat" than negative affect for individuals with binge eating. This may suggest new treatment directions, such as cognitive defusion from TSF when patients experience "feeling fat." The utility of HRV in monitoring "feeling fat" is questionable.

Unusual renal displacement due to massive splenomegaly: a rare case report and review of literature.

Here, the case of a female patient in her late 60s, who presented to hospital for a scheduled health check relating to a history of myelofibrosis for the previous 9 years, is described. She recently experienced weight loss and abdominal distention. Physical examination revealed no abnormality or tenderness. Laboratory examination showed decreased blood cells, platelets and haemoglobin, and normal renal function. Ultrasound and computed tomography scans revealed a massively enlarged spleen and displaced and compressed left kidney with abnormal features, but normal right kidney. The patient declined surgery and her myelofibrosis was treated with ruxolitinib, with a recommendation of annual follow-up observation. Despite many recorded cases of left renal displacement caused by splenomegaly, it is very rare for the left kidney to be pushed across the midline to the right side by an enlarged spleen. This article explores the causes and management of this uncommon condition and provides a review of previous literature reports with the aim of enhancing the understanding of unusual renal displacement due to massive splenomegaly, and its potential treatment options.

An intelligent fluorescence sensing platform based on entropy-driven toehold-mediated strand displacement cycle reaction for point-of-care testing of miRNA.

BACKGROUND: MicroRNA (miRNA) has gradually become an emerging biomarker for early diagnosis and prognosis of various diseases due to its specific gene expression and high stability. With the development of molecular diagnosis and point-of-care testing (POCT) technology, developing simple, fast, sensitive, efficient, and low-cost miRNA sensors is of great significance for clinical applications and emergency rapid diagnosis. At present, entropy-driven toehold mediated chain displacement reaction, as a promising enzyme free isothermal amplification technique, is an important tool for ultra-sensitive biosensing applications. RESULTS: In this study, we used gold nanoparticles (AuNPs) as carriers and quenchers, modified them using self-assembled triple chain composite substrates AuNPs@A@B1/B2, and used dual reporter molecules for cascade cyclic amplification to amplify fluorescence signals, which proposed a fluorescent biosensor based on this reaction and build an intelligent fluorescence sensing platform for rapid detection of miRNA. We designed a highly specific self-programmable sensor using the acute ischemic stroke (AIS) biomarker miRNA-125a-5p as a sample, and achieved sensitive detection of miRNA in the range of 0.01 µM∼10 µ M under optimal conditions. It broke through the traditional detection limitations of weak signals and liberated the fluorescence detection environment. SIGNIFICANCE: In summary, this creative miRNA biosensor combined with POCT has demonstrated extraordinary detection potential, broad application prospects in the early diagnosis and prognosis monitoring of AIS, provides a novel miRNA universal detection strategy for the fields of biological and life sciences.

SELFNet: Denoising Shear Wave Elastography Using Spatial-temporal Fourier Feature Networks.

OBJECTIVE: Ultrasound-based shear wave elastography offers estimation of tissue stiffness through analysis of the propagation of a shear wave induced by a stimulus. Displacement or velocity fields during the process can contain noise as a result of the limited number of acquisitions. With advances in physics-informed deep learning, neural networks can approximate a physics field by minimizing the residuals of governing physics equations. METHODS: In this research, we introduce a shear wave elastography Fourier feature network (SELFNet) using spatial-temporal random Fourier features within a physics-informed neural network framework to estimate and denoise particle displacement signals. The network uses a sparse mapping to increase robustness and incorporates the governing equations for regularization while simultaneously learning the mapping of the shear modulus. The method was evaluated in datasets from tissue-mimicking phantom of lesions and ex vivo tissue. RESULTS: The findings indicate that SELFNet is capable of smoothing out the noise in phantom lesions with different stiffness and sizes, outperforming a reference Gaussian filtering method by 17% in relative ℓ2 error, 45% in reconstruction root-mean-square error. Furthermore, the ablation study suggested that SELFNet can prevent over-fitting through the Fourier feature mapping module. An ex vivo study confirmed its applicability to different types of tissue. CONCLUSION: The implementation of SELFNet shows promise for shear wave elastography with limited acquisitions. In this context, subject to successful translation, it has the potential to be extended to clinical applications, such as the diagnosis of cancer or liver disease.

This Concept paper provides an overview of previous efforts on developments of synthetic gene circuits through utilization of RNA strand displacement, including our endeavors in this field. Moreover, future prospects, potential applications and challenges of the genetically expressed RNA strand displacement technology are also discussed.

Pain, Function and Quality of Life in Temporomandibular Disorder Patients With Different Disc Positions.

BACKGROUND: Whether pain, jaw function and quality of life are correlated with disc positions is controversial, and similar studies evaluating disc positions by magnetic resonance imaging (MRI) are very limited. OBJECTIVE: This study evaluated the pain, mandibular function and quality of life of the temporomandibular disorders (TMDs) patients with different disc positions according to MRI, and the relationship among them. METHODS: Three hundred and thirty-five participants were included. Patients completed questionnaires included the Numeric Rating Scale (NRS), Jaw Functional Limitation Scale 8-item (JFLS-8), the Generalised Anxiety Disorder 7-item (GAD-7), Patient Health Questionnaire 9-item (PHQ-9) and Oral Health Impact Profile for TMD (OHIP-TMD). MRI was conducted to evaluate these diagnoses, resulting in the identification of three distinct categories: normal positioning (NP), disc displacement with reduction (DDwR) and disc displacement without reduction (DDwoR). RESULTS: Participants had the mean age of 28.55 ± 11.10 years (80.90% women). DDwR and DDwoR had a higher percentage of females compared with NP. Significant differences existed among patients in all questionnaires. The DDwoR group had significantly the highest pain, functional limitation and the worst quality of life. Moreover, they experienced the most difficulties in chewing tough foods, yawning, experiencing pain and psychological discomfort. Moreover, the multivariate regression showed that age, female gender, diagnosis as DDwoR, GAD-7 and PHQ-9 were significantly linked to higher functional limitation. Worse quality of life was associated with age, diagnosis as DDwoR, GAD-7 and PHQ-9. CONCLUSIONS: Among patients with different disc positions, DDwoR showed the highest pain, functional limitation and the worst quality of life. Also, NP showed a proportion of chronic pain. Physical pain, psychological discomfort and chewing tough food were regarded as the most impaired. Women who experience anxiety and depression tended to have a higher propotion of dysfunction and a lower quality of life.

Multiple quadrants displacement tracking control of independent metering electro-hydraulic system.

Aiming at the oscillation caused by the hydraulic cylinder of independent metering system (IMS) running between multiple working quadrants, a novel multiple quadrants switching displacement tracking control strategy is proposed in this paper. In this control strategy, both the cylinder chamber pressure under resistance and overrunning conditions are controlled by the inlet valve, and the outlet valve is utilized to control the displacement of cylinder. This method allows the hydraulic cylinder to always run in energy-efficient. When the working quadrant changes, the valve's working modes are unchanged, which avoids oscillation caused by changes of valves working modes in principle. And a reduced-order active disturbance rejective displacement controller and an active disturbance rejective pressure controller are designed to get high-precision tracking of the displacement and pressure. Numerous experimental results show that the proposed method is reasonable and effective, hydraulic cylinder operates smoothly between multiple quadrants, the pressure and displacement controllers have good anti-interference ability and robustness, and the energy consumption can be reduced by more than 23% compared to the traditional constant pressure valve control system.

A multistrategy differential evolution algorithm combined with Latin hypercube sampling applied to a brain-computer interface to improve the effect of node displacement.

Injection molding is a common plastic processing technique that allows melted plastic to be injected into a mold through pressure to form differently shaped plastic parts. In injection molding, in-mold electronics (IME) can include various circuit components, such as sensors, amplifiers, and filters. These components can be injected into the mold to form a whole within the melted plastic and can therefore be very easily integrated into the molded part. The brain-computer interface (BCI) is a direct connection pathway between a human or animal brain and an external device. Through BCIs, individuals can use their own brain signals to control these components, enabling more natural and intuitive interactions. In addition, brain-computer interfaces can also be used to assist in medical treatments, such as controlling prosthetic limbs or helping paralyzed patients regain mobility. Brain-computer interfaces can be realized in two ways: invasively and noninvasively, and in this paper, we adopt a noninvasive approach. First, a helmet model is designed according to head shape, and second, a printed circuit film is made to receive EEG signals and an IME injection mold for the helmet plastic parts. In the electronic film, conductive ink is printed to connect each component. However, improper parameterization during the injection molding process can lead to node displacements and residual stress changes in the molded part, which can damage the circuits in the electronic film and affect its performance. Therefore, in this paper, the use of the BCI molding process to ensure that the node displacement reaches the optimal value is studied. Second, the multistrategy differential evolutionary algorithm is used to optimize the injection molding parameters in the process of brain-computer interface formation. The relationship between the injection molding parameters and the actual target value is investigated through Latin hypercubic sampling, and the optimized parameters are compared with the target parameters to obtain the optimal parameter combination. Under the optimal parameters, the node displacement can be optimized from 0.585 to 0.027 mm, and the optimization rate can reach 95.38%. Ultimately, by detecting whether the voltage difference between the output inputs is within the permissible range, the reliability of the brain-computer interface after node displacement optimization can be evaluated.

Violation of Economic, Social, Cultural, and Environmental Rights as Seen Through the Eyes of Displaced Women in the Northern Zone of Colombia.

Forced displacement results in social inequalities negatively affecting the well-being of displaced women. Addressing the economic, social, cultural, and environmental dimensions of their vulnerability is crucial. This article examines the perspectives of 59 displaced women in informal settlements in northern Colombia on violations of their rights. Interpretative phenomenological analysis reveals economic hurdles, such as limited access to decent work and workplace discrimination. Social barriers, like stigmatization and discrimination, impede integration and access to essential services. Despite challenges, increasing awareness and implementing inclusive policies can enhance the living conditions of displaced women.

A Systematic Review of the Optimal Management of Pediatric Distal Radius Displacement Fractures: Open Reduction and Internal Fixation Versus Cast Placement.

Distal radius fractures are among the most common pediatric injuries, affecting thousands of children each year. These fractures often require clinical intervention to reduce displacement and ensure the proper healing of the growth plate and wrist bone. The primary objective of this comprehensive analysis is to compare the effectiveness of open reduction and internal fixation (ORIF) versus cast placement in the treatment of pediatric distal radius fractures, with the aim of identifying the optimal treatment approach. Therefore, a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted on pediatric distal radius displacement fractures using extensive database searches from 2000 to 2024 for specific keywords, ensuring transparency and reproducibility. Our findings indicate that higher displacement necessitates ORIF to minimize long-term complications and ensure better functional outcomes for pediatric patients. Rare studies comparing ORIF and cast placement are analyzed, emphasizing the advantages and limitations of each approach. The document concludes that the choice between ORIF and casting depends on factors such as fracture severity, patient's age, and specific characteristics of the injury to ensure optimal outcomes in pediatric distal radius fracture management. In conclusion, our data suggests that ORIF and cast placement each have pros and cons for pediatric distal radius fractures, with the best treatment depending on fracture specifics and patient factors, but neither method is clearly superior for long-term outcomes.

Combined PCL instabilities cannot be identified using posterior stress radiographs in external or internal rotation: A cadaveric study.

PURPOSE: Posterior stress radiography is recommended to identify isolated or combined posterior cruciate ligament (PCL) deficiencies. The posterior drawer in internal (IR) or external rotation (ER) helps to differentiate between these combined instabilities. The purpose of this study was to evaluate posterior stress radiography (PSR) in isolated and combined PCL deficiency with IR and ER compared to PSR in neutral rotation (NR) for diagnosing combined PCL instabilities. METHODS: Six paired fresh-frozen human cadaveric legs (n = 12) were mounted in a Telos device for PSR. The tibia was rotated using an attached foot apparatus capable of rotating the foot 30° internally and externally. A posterior tibial load of 15 kp (147.1 N) was applied to the tibial tubercle at 90° knee flexion, and a lateral radiograph was obtained. This was repeated with the foot in 30° IR and ER. The PCL, posterolateral complex (PLC), and posteromedial complex (PMC) were sectioned in six knees, while the PMC was sectioned before the PLC in the other six knees. Posterior tibial displacement (PTD) was measured radiographically. Statistical analysis was performed using a two-way ANOVA and a mixed model with Bonferroni correction, and the significance was set at p < 0.05. Furthermore, intra- and interobserver reliability was determined. RESULTS: Cutting the PCL significantly increased the radiographic PTD by 9.8 ± 1.8 mm (side-to-side difference compared to the intact state of the knee, n = 12; p < 0.001). This further increased to 12.2 ± 2.3 mm (n = 6; p < 0.01) with an additional PLC deficiency and to 15.4 ± 3.4 mm (n = 6; p < 0.05) with an additional PMC deficiency. A combined PLC and PMC deficiency resulted in an increase of the PTD to 15.9 ± 4.5 mm (n = 12; p < 0.01). In the PCL/PLC deficient state, ER did not demonstrate a higher PTD, compared to the NR and IR posterior drawer. In the PCL/PMC deficient state in IR, PTD was 1.6 ± 0.7 mm (p < 0.01) higher compared to NR and 3.2 ± 1.9 mm (p < 0.05) higher compared to ER. We showed excellent intra- and interobserver reliability (0.987-0.997). CONCLUSION: Combined PCL instabilities resulted in a significant increase in posterior tibial displacement in posterior stress radiographs. However, PSR in IR or ER was unable to differentiate between these combined instabilities. Based on our data, additional stress radiographs in rotation are unlikely to provide any diagnostic benefit in the clinical setting. LEVEL OF EVIDENCE: There is no level of evidence as this study was an experimental laboratory study.

An Auto-Reading probe system for detecting deletion mutations In liquid biopsy with direct quantification of mutation abundance.

Background: Deletion mutations have been confirmed to be closely related to the occurrence and progression of different hereditary diseases and tumors. Specifically, the deletion of a small number of bases is more challenging to be captured and differentiated. In non-invasive prenatal testing (NIPT) and liquid biopsy targeting circulating tumor DNA, obtaining accurate mutation abundance in targeted DNA is a crucial step in the detection process. However, the quantification of mutation abundance with existing methods is not accurate enough. Results: Herein, we developed the " Auto-Reading" probe detection system based on our previous work. Through theoretical modeling and experimental calculations, we verified the successful application of our system in NIPT and early cancer diagnosis, enabling effective discrimination of different mutant abundances. Significance: Our method overcomes the interference of reaction concentrations on signal detection, allowing direct quantification of mutation abundance without the need for purification of PCR products. The detection system is cost-effective and feasible for laboratory use. We believe the system will facilitate broad applications in mutation detection.

A Scoping Review of the Intimate Partner Violence Literature Among Afghans Across Contexts.

The purpose of this scoping review was to ascertain the scope and nature of the literature focused on intimate partner violence (IPV) among Afghans across contexts, including Afghanistan. The scoping review adopted a systematic approach to search for, identify, and include peer-reviewed articles published in English. Fifty-two articles were retained in the final analysis, which generated results on IPV prevalence; multi-level risk and protective factors; qualitatively derived contextual factors; associations of IPV with adverse physical and psychological outcomes; IPV-related help-seeking behaviors; programs and interventions; the role of religion; IPV-related policies; and the role of fiction. Findings indicate that past-year physical IPV prevalence ranged from 52% to 56% in Afghanistan and 79.8% among Afghan refugees displaced in Iran. Studies conducted in Afghanistan identified a range of IPV risk factors occurring at the individual (e.g., age and employment), interpersonal/household (e.g., acceptance of IPV and violence perpetrated by in-laws), and societal levels (e.g., conflict/displacement). The findings highlight a rich literature on IPV in Afghanistan and significant gaps in IPV research across the Afghan diaspora and in contexts of displacement and resettlement. The results advance understanding of the drivers of IPV in the diverse Afghan population and highlight context-specific gaps, and needs for intervention and future research. These gaps indicate the importance of conducting research elucidating how risk and protective factors associated with IPV shift in forced migration and resettlement, and an urgent need for the development and testing of services and programs that respond to the specific needs of Afghan women experiencing IPV across contexts.
