AIE-FMIPIL exhibited selective binding to 4-NP because of the imprinted sites. AIE-FMIPIL was adopted to detect 4-NP in environmental samples.Continuous biosensors provide real-time information about biochemical processes occurring in the environment of interest and are therefore highly desirable in research, diagnostics and industrial settings. Although remarkable progress has been made in the field of biosensing, most biosensors still rely on batch processes and, thus, are not suited to perform continuous measurements. Recently, however, it has been shown that by combining affinity-based nanoswitches with state-dependent readout platforms, the necessity for batch processes can be overcome and affinity-based continuous biosensing can be achieved. In this review, we first provide an overview of affinity-based continuous biosensing and discuss the required components to achieve this goal. More specifically, we summarize the strategies that have been applied to develop and tune both protein and nucleic acid-based switches, as well as readout strategies that can be applied in combination with the former. Afterwards, biosensors in which both elements were already integrated and hence enabled continuous measurements are reviewed. We also discuss the challenges and opportunities associated with each approach and therefore believe this review can help to encourage and guide future research towards continuous biosensing.A facile solvothermal synthesis approach for chemical composition control in ternary Bi-S-I systems is reported by simply controlling the sulfide concentration. We demonstrate the application of these bismuth-based ternary mixed-anion compounds as high capacity anode materials in rechargeable batteries. Cells utilising Bi13S18I2 achieved an initial capacity value of 807 mA h g-1, while those with BiSI/Bi13S18I2 a value of 1087 mA h g-1 in lithium-ion battery systems.Ibrutinib, an oral small-molecule targeted drug, has been the first Bruton tyrosine kinase (BTK) inhibitor in the world to be approved for the market. It works by regulating cell proliferation, apoptosis and migration, and has been proven to exhibit high efficacy and good safety in the treatment of B-cell lymphomas, including chronic lymphocytic leukemia or small lymphocytic lymphoma and mantle cell lymphoma. However, some patients inevitably have drug resistance and disease recurrence, resulting in a poor prognosis. This article serves as a clinical reference by summarizing the related literature on ibrutinib resistance inhibitors.Loteprednol etabonate is a soft corticosteroid that is rapidly deactivated after reaching the general circulation, displaying good local activity and a high therapeutic index without inducing systemic side effects. In 2021, Kala Pharmaceuticals launched Eysuvis (loteprednol etabonate ophthalmic suspension) 0.25% in the U.S. for the short-term (up to 2 weeks) treatment of the signs and symptoms of dry eye disease. Approval by the Food and Drug Administration (FDA) was based on results from one phase II trial and three phase III trials showing Eysuvis significantly improved both the signs and symptoms of dry eye disease and was well tolerated. Eysuvis is a novel loteprednol etabonate nanosuspension formulation developed by Kala using its AMPPLIFY mucus-penetrating particle (MPP) drug delivery technology. Use of this MPP formulation results in enhanced penetration of loteprednol etabonate into target tissue on the ocular surface. Eysuvis is the first FDA-approved ocular corticosteroid indicated for dry eye disease.Dapagliflozin is an oral agent for type 2 diabetes mellitus (T2DM) belonging to the sodium/glucose cotransporter 2 inhibitor (SGLT2-I) class of antihyperglycemic medications. In clinical trials, dapagliflozin has also been shown to reduce cardiovascular and major renal events. In the DAPA-CKD trial, dapagliflozin significantly reduced the composite renal outcome in patients with chronic kidney disease (CKD). Dapagliflozin represents a new pharmacologic option for reducing CKD progression in patients with and without diabetes.Orladeyo, a once-daily oral formulation of berotralstat (formerly BCX-7353), is a novel oral small-molecule drug developed by BioCryst Pharmaceuticals for the prevention of hereditary angioedema (HAE) attacks. It was first approved by the U.S. Food and Drug Administration (FDA) in 2020, and in 2021 also gained approval for marketing in Japan and the European Union. Preclinical and phase I studies showed promising efficacy and safety, and several multicenter international Angioedema Prophylaxis (APeX) phase II and III trials have since been initiated to further evaluate berotralstat. The ongoing phase III APeX-2 trial showed a 67% reduction in HAE attacks at the standard 150-mg dosing. Mild to moderate gastrointestinal side effects are most commonly seen and minimal serious adverse effects have been reported. Other first-line therapies for HAE prophylaxis rely on burdensome subcutaneous or intravenous routes. Thus far berotralstat has shown to be effective and well tolerated for HAE prophylaxis with the convenience of once-daily oral dosing.Plant cells use different structural mechanisms, either constitutive or inducible, to defend themselves from fungal infection. Encapsulation is an efficient inducible mechanism to isolate the fungal haustoria from the plant cell protoplast. Conversely, pectin, one of the polymeric components of the cell wall, is a target of several pectolytic enzymes in necrotrophic interactions. Here, a protocol to detect pectin and fungal hyphae through optical microscopy is presented. The pectin-rich encapsulation in the cells of coffee leaves infected by the rust fungus Hemileia vastatrix and the mesophyll cell wall modification induced by Cercospora coffeicola are investigated. Lesioned leaf samples were fixed with the Karnovsky solution, dehydrated, and embedded in glycol methacrylate for 2-4 days. All steps were followed by vacuum-pumping to remove air in the intercellular spaces and improve the embedding process. The embedded blocks were sectioned into 5-7 µm thick sections, which were deposited on a glass slide covered with water and subsequently heated at 40 °C for 30 min. Next, the slides were double-stained with 5% cotton blue in lactophenol to detect the fungus and 0.05% ruthenium red in water to detect pectin (acidic groups of polyuronic acids of pectin). Fungal haustoria of Hemileia vastatrix were found to be encapsulated by pectin. In coffee cercosporiosis, mesophyll cells exhibited dissolution of cell walls, and intercellular hyphae and conidiophores were observed. The method presented here is effective to detect a pectin-associated response in the plant-fungi interaction.The DNA fiber assay is a simple and robust method for the analysis of replication fork dynamics, based on the immunodetection of nucleotide analogs that are incorporated during DNA synthesis in human cells. However, this technique has a limited resolution of a few thousand kilobases. Consequently, post-replicative single-stranded DNA (ssDNA) gaps as small as a few hundred bases are not detectable by the standard assay. Here, we describe a modified version of the DNA fiber assay that utilizes the S1 nuclease, an enzyme that specifically cleaves ssDNA. In the presence of post-replicative ssDNA gaps, the S1 nuclease will target and cleave the gaps, generating shorter tracts that can be used as a read-out for ssDNA gaps on ongoing forks. These post-replicative ssDNA gaps are formed when damaged DNA is replicated discontinuously. They can be repaired via mechanisms uncoupled from genome replication, in a process known as gap-filling or post-replicative repair. Because gap-filling mechanisms involve DNA synthesis independent of the S phase, alterations in the DNA fiber labeling scheme can also be employed to monitor gap-filling events. Altogether, these modifications of the DNA fiber assay are powerful strategies to understand how post-replicative gaps are formed and filled in the genome of human cells.The present article introduces a method for fabricating and operating a pneumatic valve to control particle concentration using a microfluidic platform. This platform has a three-dimensional (3D) network with curved fluid channels and three pneumatic valves, which create networks, channels, and spaces through duplex replication with polydimethylsiloxane (PDMS). The device operates based on the transient response of a fluid flow rate controlled by a pneumatic valve in the following order (1) sample loading, (2) sample blocking, (3) sample concentration, and (4) sample release. The particles are blocked by thin diaphragm layer deformation of the sieve valve (Vs) plate and accumulate in the curved microfluidic channel. The working fluid is discharged by the actuation of two on/off valves. As a result of the operation, all particles of various magnifications were successfully intercepted and disengaged. When this technology is applied, the operating pressure, the time required for concentration, and the concentration rate may vary depending on the device dimensions and particle size magnification.High-Intensity Interval Training (HIIT) and accumulated exercises are two time-efficient programs to improve health in humans and animal models. However, to date, there are no studies on whether HIIT performed in an accumulated fashion is as effective as a traditional HIIT performed with single daily sessions in improving health markers. This paper presents the effects of a new HIIT protocol, called accumulated HIIT, on body weight gain, maximal oxygen consumption (VO2max), and cardiac hypertrophy in young Wistar rats. Sixty-day-old male Wistar rats were assigned to three groups untrained (UN; n = 16), HIIT performed with single daily sessions (1-HIIT; n = 16), and HIIT performed with three daily sessions (3-HIIT; n = 16). Body weight and VO2max were recorded before and after the training period. The VO2max measurements were taken using a metabolic analyzer at the maximal running velocity (Vmax). The training was performed for both HIIT groups five days per week over eight weeks with the same weekly progression of the exercise intensity (85-100% Vmax). The 1-HIIT group performed single daily sessions (6 bouts of 1 min interspersed with 1 min of passive recovery). The 3-HIIT group performed three daily sessions (2 bouts of 1 min interspersed with 1 min of passive recovery with an interval of 4 h between bouts). After the last VO2max test, the rats were euthanized, and their hearts were harvested and weighed. The results showed that 3-HIIT had similar beneficial effects to 1-HIIT in preventing body weight gain, improving VO2max, and inducing cardiac hypertrophy. These findings reveal for the first time the efficacy of an accumulated HIIT protocol on the health markers of young Wistar rats. This new HIIT protocol may be more feasible than traditional HIIT protocols as exercise can be split into very short sessions throughout a day in this new approach.The mitotic bipolar kinesin-5 motors perform essential functions in spindle dynamics. These motors exhibit a homo-tetrameric structure with two pairs of catalytic motor domains, located at opposite ends of the active complex. This unique architecture enables kinesin-5 motors to crosslink and slide apart antiparallel spindle microtubules (MTs), thus providing the outwardly-directed force that separates the spindle poles apart. Previously, kinesin-5 motors were believed to be exclusively plus-end directed. However, recent studies revealed that several fungal kinesin-5 motors are minus-end directed at the single-molecule level and can switch directionality under various experimental conditions. The Saccharomyces cerevisiae kinesin-5 Cin8 is an example of such bi-directional motor protein in high ionic strength conditions single molecules of Cin8 move in the minus-end direction of the MTs. read more It was also shown that Cin8 forms motile clusters, predominantly at the minus-end of the MTs, and such clustering allows Cin8 to switch directionality and undergo slow, plus-end directed motility.
