The role of clinical breast examination (CBE) for early detection of breast cancer is extremely important in lower-middle-income countries (LMICs) where access to breast imaging is limited. Our study aimed to describe the outcomes of a community outreach breast education, home CBE and referral program for early recognition of breast abnormalities and improvement of breast cancer awareness in a rural district of Pakistan.

Esophageal cancer (EC) is a deadly disease with limited therapeutic options. Although circulating tumor DNA (ctDNA) could be a promising tool in this regard, the availiable evidence is limited. We performed a systematic review and meta-analysis to summarize the clinical applicability of the next-generation sequencing (NGS) and droplet digital polymerase chain reaction (ddPCR) technology on the ctDNA detection of the EC and listed the current challenges.

This paper addresses the challenge of fault detection in Wireless Sensor Networks (WSNs), commonly used in fields like environmental monitoring and healthcare. WSNs, prone to various faults due to their deployment in unpredictable environments, require effective solutions for fault detection. Traditional machine learning approaches show limitations such as unsuitability for streaming data and the detection of a single fault type.

Electrochemical determination of salbutamol in aqueous solutions with UiO-66/rGO-modified electrodes
The synthesis of the UiO-66/rGO material involved combining UiO-66 with reduced graphene oxide (rGO). This resulting composite found application in the electrochemical determination of salbutamol (SAL) through modification of a glassy-carbon electrode (GCE) with UiO-66/rGO. Differential pulse voltammetry served as the chosen technique, offering a wide linear range spanning 1–160 μM and demonstrating a low limit of detection at 0.84 μM

Detection of nitroaromatic explosives (NAEs) is very important in terms of national security as well as the damage they cause to living things and the environment. The precision detection of these is a very important issue to reduce their harmful effects and take the necessary precautions. Electron-rich polyaromatic fluorescent materials are highly sensitive and selective in the detection of NAEs in terms of their fluorometric quenching abilities.

The plasmon characterization of AgNS on paper was systematically investigated by the diffuse reflectance spectroscopy. The fabricated paper-based SERS substrates were used to detect melamine in an aqueous solution and to determine the influence of type RAs on the enhancement factor (EF) and signal uniformity of SERS substrates. Among the four types of RAs, the SERS substrates used NaBH4 have the highest SERS signal with the limit of detection of 10-8 M for melamine and the EF = 2.3 × 109 .

In this study, we present the experimental evidence demonstrating the utility of electrical double layer (EDL)-induced ion accumulation, using sodium (Na+) ion in water as a model substance, on a negatively charged nanostructured surface, specifically thermally grown silicon dioxide (SiO2). This novel approach, termed Ion Surface Accumulation (ISA), aims to enhance the performance of nanostructured porous silicon (PSi) interferometers in optical refractometric applications.

Pancreatic cancer is an aggressive cancer with dismal prognosis, urgently necessitating better biomarkers to improve therapeutic options and early diagnosis. Traditional approaches of biomarker detection that consider only one aspect of the biological continuum like gene expression alone are limited in their scope and lack robustness in identifying the key regulators of the disease.

Identifying the complete repertoire of genes that drive cancer in individual patients is crucial for precision oncology. Most established methods identify driver genes that are recurrently altered across patient cohorts. However, mapping these genes back to patients leaves a sizeable fraction with few or no drivers, hindering our understanding of cancer mechanisms and limiting the choice of therapeutic interventions.

Structural variants (SVs) are implicated in the etiology of Mendelian diseases but have been systematically underascertained owing to sequencing technology limitations. Long-read sequencing enables comprehensive detection of SVs, but approaches for prioritization of candidate SVs are needed.

Exome sequencing (ES) is becoming more widely available in prenatal diagnosis. However, data on its clinical utility and integration into clinical management remain limited in practice. Herein, we report our experience implementing prenatal ES (pES) in a large cohort of fetuses with anomalies detected by ultrasonography using a hospital-based in-house multidisciplinary team (MDT) facilitated by a three-step genotype-driven followed by phenotype-driven analysis framework.

The deregulation of microRNA-140 (miRNA-140) has been reported to be involved in the human pathogenesis of Osteoarthritis (OA). However, in Vietnam, to our knowledge, there is a limited study of evaluation of a miRNA-140 expression. The commercial kits for the quantitation of miRNA-140 are more expensive.

This study overcomes the above limitation. At the noise pixel detection step, the algorithm uses an adaptively sized window to help distinguish the noise candidate points as real noise pixels or texture pixels based on the observation that the noise pixels are usually isolated pixels, whose value changes suddenly compared to the surrounding values.

Ebook "Molecular techniques in food biology: Safety, biotechnology, authenticity and traceability" explores all aspects of microbe-food interactions, especially as they pertain to food safety. Traditional morphological, physiological, and biochemical techniques for the detection, differentiation, and identification of microorganisms have severe limitations. As an alternative, many of those responsible for monitoring food safety are turning to molecular tools for identifying foodborne microorganisms.

Outbreaks of the Southern rice black-streaked dwarf virus (SRBSDV) have caused significant losses in many rice-growing areas in Vietnam, especially in both North and Central Vietnam in recent years. To detect the virus, traditional reverse transcription polymerase chain reaction (RT-PCR) methodology and immunoassays are currently employed. RT-PCR is accurate but requires expensive chemicals and instruments, as well as complex procedures that limit its applicability for field tests.
