Western blot is a popular biomolecular analysis method for measuring the relative quantities of independent proteins in complex biological samples. However, variability in quantitative western blot data analysis poses a challenge in designing reproducible experiments. The lack of rigorous quantitative approaches in current western blot statistical methodology may result in irreproducible inferences. Here we describe best practices for the design and analysis of western blot experiments, with examples and demonstrations of how different analytical approaches can lead to widely varying outcomes. To facilitate best practices, we have developed the blotRig tool for designing and analyzing western blot experiments to improve their rigor and reproducibility. The blotRig application includes functions for counterbalancing experimental design by lane position, batch management across gels, and analytics with covariates and random effects.

In this work, pure and heterostructured g-C3N4/CuO photocatalyst materials were prepared using a combination of thermal decomposition and hydrothermal techniques. The phase and purity of the catalysts were examined using powder X-ray diffraction (XRD). The prepared catalysts were also assessed using different systematic techniques, which demonstrated that the addition of CuO to the g-C3N4 matrix significantly altered the particle size, crystallinity, morphology, and energy bandgap. Heterojunction formation and interfacial contact between CuO and g-C3N4were confirmed by TEM and XPS analyses. The photocatalytic activity of the g-C3N4/CuO nanocomposite was assessed by its ability to break down Methylene Blue (MB), an organic contaminant, under visible-light exposure. Remarkably, the g-C3N4/CuO catalyst demonstrated rapid photocatalytic degradation of MB, achieving 98 % breakdown within 40 min. The increased degradation efficiency of g-C3N4/CuO is due to its lower energy bandgap, enhanced charge transport, and lower charge recombination compared to pure CuO and g-C3N4. Therefore, constructing a g-C3N4/CuO heterostructure could be a promising technique for sewer water treatment.

Evaluation of Gastrointestinal Stromal Tumors (GIST) during initial clinical staging, surgical intervention, and postoperative management can be challenging. Current imaging modalities (e.g., PET and CT scans) lack sensitivity and specificity. Therefore, advanced clinical imaging modalities that can provide clinically relevant images with high resolution would improve diagnosis. KIT is a tyrosine kinase receptor overexpressed on GIST. Here, the application of a specific DNA aptamer targeting KIT, decorated onto a fluorescently labeled porous silicon nanoparticle (pSiNP), is used for the in vitro & in vivo imaging of GIST. This nanoparticle platform provides high-fidelity GIST imaging with minimal cellular toxicity. An in vitro analysis shows greater than 15-fold specific KIT protein targeting compared to the free KIT aptamer, while in vivo analyses of GIST-burdened mice that had been injected intravenously (IV) with aptamer-conjugated pSiNPs show extensive nanoparticle-to-tumor signal co-localization (>90% co-localization) compared to control particles. This provides an effective platform for which aptamer-conjugated pSiNP constructs can be used for the imaging of KIT-expressing cancers or for the targeted delivery of therapeutics.

In this study, a cladding-modified fiber-optic sensor is reported for NO2 gas detection. Monitoring the purity of air is the need of the hour, with the growing technologies. Hence, in this work, Ag-doped CdS is coated over the cladding-removed region of 3 cm length by Chemical Bath Deposition (CBD) which acts as the gas-sensing medium. Ag–CdS is coated over four fibers each with a different coating duration of 10 min, 20 min, 30 min and 40 min. Characterization of Ag–CdS is done by Scanning Electron Microscope (SEM), UV-visible absorption spectroscopy and UV-visible reflectance spectroscopy. The spectral response for different concentrations of NO2 is studied on the four fibers separately, and it is analyzed and compared. The minimum detection limit is 100 ppm and the response time is 10 min. Out of the four fibers, Ag–CdS-30 exhibited the best response with a sensitivity of 15.5%. The results are compared with cladding-modified fiber coated with CdS, which was reported previously. The effect of Ag-doping is analyzed. Ag-doped-CdS was coated over cladding-removed region of optical fibers, with the same coating durations used for CdS. Among these optical fibers, Ag-CdS-30 exhibited best response towards NO2 gas. But the sensitivity of CdS-20 was higher when compared with Ag-CdS-30. To understand the reasons for its better performance, certain properties of both the materials were analysed.

Objective: This review evaluates current literature on intensity selection, perceptual responses, activity enjoyment and adherence rates of exergaming. Methods: The literature search identified manuscripts that investigated exercise intensity, perceptual responses, or exercise adherence of exergaming in young adults. Results: Based on results of 29 studies, the current review suggest some exergaming activities have the potential to elicit moderate to vigorous exercise intensity and could potentially be substituted for traditional exercise. Additionally, exergame activities may aid in the start of exercise adherence by lowering the individual's perceived exertion when playing exergames. Exergaming not only has the potential to enhance enjoyment through an exercise objective but also through the distracting nature of video games. Conclusions: Exergaming shows potential to be substituted for traditional exercise and could offer a new, varied form of exercise for sedentary individuals. Future research should examine the influence of exergaming experience on intensity selection and adherence rates. [ABSTRACT FROM AUTHOR]
