Engineered living materials (ELMs) derive functionality from both a polymer matrix and the behavior of living cells within the material. The long-term goal of this work is to enable a system of ELM-based medical devices with both mechanical and bioactive functionality. Here, we fabricate multifunctional, stimuli-responsive ELMs comprised of acrylic hydrogel matrix and Escherichia coli. These ELMs undergo controlled changes in form and have a controlled release of bacteria from the composite. We hypothesize that the mechanical forces associated with cell proliferation within a covalently-crosslinked, non-degradable hydrogel are responsible for both phenomena. At constant cell loading, increased hydrogel elastic modulus significantly reduces both cell delivery and volume change associated with cell proliferation. ELMs that change volume over 100 % also result in ~106 colony forming units/mL in the growth medium over 2 h after 1 day of growth. At constant monomer feed ratios, increased cell loading leads to significantly increased cell delivery. mTOR inhibitor Finally, these prokaryotic ELMs were investigated for their potential to deliver a probiotic that can reduce the proliferation of a uropathogen in vitro. Controlling the long-term delivery of bacteria could potentially be used in biomedical applications to modulate microbial communities within the human body.Biosensors are advanced devices for analysis of composition of blood, urine, environmental samples, and many other media. Their current development is tightly linked with nanomaterials, such as zeolites and zeolitic imidazolate framework (ZIFs). The present review describes electrochemical (amperometric, conductometric, ISFET) and optical (fluorescent and colorimetric) biosensors that incorporate zeolites and ZIFs in their biorecognition elements. The biosensors are based on immobilized enzymes (such as glucose oxidase, urease, and acetylcholinesterase), antibodies, DNA, and aptamers. The review present reasons for application of these nanomaterials, and discusses advantages of zeolite- and ZIF-containing biosensors over other biosensors. link2 In most cases, the biosensors have improved sensitivity, better limit of detection, wider linear range, and other improved characteristics. It is demonstrated that immobilization of biomolecules such as enzymes or antibodies on the surface of zeolites and ZIFs enables creation of unique advanced biosensors that have a potential for further development and practical applications.
Hypertension (HTN) is a major public health concern, and elevated blood pressure (BP) is a distinct risk factor for all - causes of morbidity and mortality.

Considering the growing evidence of yoga interventions in the management of hypertension, the objective of the current randomized controlled study is to assess the effect of OM chanting and Yoga nidra (Relaxation technique) on BP and lipid profile in individuals with HTN.

Eighty patients with diagnosed HTN were recruited and randomized equally to either the experimental group or the control group. Patients in the experimental group received a combination of OM chanting and Yoga nidra, five days a week for a period of 2 months and patients in the control group continued with their regular conventional medications. BP and lipid profile parameters were assessed at baseline, 30th day and 60th day for both the groups.

After 2 months of intervention, a significant (p<0.05) reduction in the BP and lipid profile was observed in the intervention group when compared to the control group. The reduction in systolic and diastolic BP and LDL were significantly (p<0.001) higher in the experimental group. In addition, there is a significant increase in HDL levels in the experimental group. No adverse events were reported during the trial period.

The current study demonstrates the efficacy of Om chanting and Yoga nidra in reducing blood pressure and improving lipid profiles in patients with HTN. These particular yoga interventions could thus be considered a safer form of complementary therapy in the management of HTN, alongside conventional management.

A dense 3D pressure discomfort threshold map could be helpful, but does not exist yet. Differences in pressure discomfort threshold for areas of the head, neck and face were recorded, to create a 3D pressure discomfort threshold map. Between 126 and 146 landmarks were placed on the left side of the head, face and neck of twenty-eight healthy participants (gender balanced). The positions of the landmarks were specified using an EEG 10-20 system-based landmark-grid on the head and a self-developed grid on the face and neck. A 3D scan was made to capture the head geometry and landmark coordinates. In a randomised order, pressure was applied on each landmark with a force gauge until the participant indicated experiencing discomfort. By interpolating all collected pressure discomfort thresholds based on their corresponding 3D coordinates, a dense 3D pressure discomfort threshold map was made. A relatively low-pressure discomfort threshold was found in areas around the nose, neck front, mouth, chin-jaw, cheek and cheekbone, possibly due to the proximate or direct location of nerves, blood veins and soft (muscular) tissue. Medium pressure discomfort was found in the neck back, forehead and temple regions. High pressure discomfort threshold was found in the back of the head and scalp, where skin is relatively thin and closely supported by bone, making these regions interesting for mounting or resting head, face and neck related equipment upon.Citrus flavonoids are attracting great interest due to their well-known beneficial effects, but many of them have not been characterized. In this work, ultra-high liquid chromatography coupled to high resolution mass spectrometry (UHPLCHRMS) was used for profiling flavonoids in citrus fruit. We proposed a strategy combining mass defect filtering (MDF) and MS/MS-based molecular networking (MMN) to handle complex UHPLC-HRMS data. The proposed strategy was explained and validated in the fruit of Citrus sinensis (L.) Osbeck, and when specific mass and mass defect windows were pre-defined, MDF enable removal of considerable un-related and/or interference MS1 peaks. link3 In citrus fruit, the number of MS1 peaks in positive and negative modes were reduced by 70.80% (from 15,113 to 4413) and 55.30% (from 5617 to 2511), respectively, and thus the potential MS features of flavonoids were retained and exposed. After MDF, an MS/MS similarity-based MMN map was constructed to cluster flavonoids with similar chemical structures. MMN facilitated the annotation of 65 unknown citrus flavonoids by using only 21 pre-identified flavonoids as references. The compounds comprised 42 polymethoxylated flavonoids, 17 flavones, 24 flavanones, and 3 flavonols. Eleven of them had not been previously reported in Citrus sinensis (L.) Osbeck to our knowledge. Results of the current work indicated that the combination of MDF and MMN is a useful strategy for removing interference MS1 peaks and performing the structural annotation of unkonwn compounds in complex samples.A new dispersive inclusion complex microextraction (DICM) approach coupled with ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) for the determination of n-nitrosamine impurities in different medicinal products is demonstrated for the first time. The proposed DICM procedures consist of a dispersive liquid phase microextraction steps employing cyclodextrin as an inclusion complex agent to extract n-nitrosamines namely N-nitrosodimethylamine (NDMA), N-nitrosodiethylamine (NDEA), N-nitrosodiisopropylamine (NDIPA), N-ethyl-N-nitrosoisopropylamine (NEIPA) and N-nitroso-di-n-butylamine (NDBA) present in the medicinal products. The sample solutions were prepared by mixing 5% (m/v) NaCl solution with 1.5 mM β-cyclodextrin and 20 mM sodium dodecyl sulphate to form a stable inclusion complex and subsequently extracted into dichloromethane as an extraction solvent. The enriched solution was reconstituted into aqueous solution prior to UPLC-MS/MS analysis. The method showed good linearity in the range of 0.036-1 ng/mL with a correlation coefficient of at least 0.995, acceptable reproducibility (RSD 0.5-5.8%, n=5), low limits of detection (0.011-0.018 ng/mL), and satisfactory relative recoveries (96-105%). The results obtained were found to be at least 10-fold more sensitive comparable to those obtained using validated direct sample dissolutions coupled with UPLC-MS/MS approach.The separation of ten flavanones (flavanone, 2'-hydroxyflavanone, 4'-hydroxyflavanone, 6-hydroxyflavanone, 7-hydroxyflavanone, naringenin, naringin, hesperetin, pinostrobin, and taxifolin) using supercritical fluid chromatography and considering achiral and chiral approaches has been studied in this work. For this purpose, different stationary phases and organic modifiers have been checked. mTOR inhibitor Considering the achiral separation, the best results were obtained with the Lichrospher 100 Diol column at 35 °C, 3 mL/min, 150 bar and a gradient of 2-propanol from 5% to 50%. The baseline separation of the ten compounds was achieved in 18 min. Using the chiral column Chiralpak AD, the separation of the ten pairs of enantiomers was obtained in 32 min. In this case, the chromatographic conditions were 30 °C, 3 mL/min, 150 bar and the organic modifier was a mixture ethanol/methanol (8020) containing 0.1% of trifluoroacetic acid applied in an elution gradient from 15% to 50%. The applicability of the proposed chiral method was assessed by analysing bee pollen samples and 2S-pinostrobin was determined in some of them.Efficient extraction is a vital step in mercury speciation. In this context, using 4-vinylbenzeneboronic acid and 9-vinylanthracene as functional monomers, a new magnetic adsorbent was fabricated according to one-pot hydrothermal approach. Various characterization results prove the as-prepared adsorbent presented abundant functional groups and saturation magnetism. Combining with magnetic solid phase extraction (MSPE), the adsorbent exhibited satisfactory entrapment performance towards different mercury species which had been pre-coordinated with dithizone to form metal-organic coordination. A series of parameters influencing the extraction performance were inspected in detail. Under the most beneficial conditions, sensitive and reliable approach to quantify trace methylmercury, ethylmercury, phenylmercury and inorganic mercury in aqueous samples was developed by the combination of HPLC/DAD. Limits of detection and precision located in the ranges of 0.012-0.074 µg/L and 2.5-9.8%, respectively. Recoveries with low, medium and high fortified contents in actual waters varied from 79.8 to 119%. Confirmatory experiments were performed to evidence the accuracy and reliability of established approach. In addition, a possible mechanism was suggested based on the chemical nature of analytes, extraction conditions and characterization results.
