Background: Sedentary behaviors (ST) are linked to children's mental health, including internalizing and externalizing problems. Research on these associations in children with overweight/obesity is limited. To this end, we examined cross-sectional and longitudinal associations between sedentary time (ST) and behavioral problems in children with overweight/obesity, followed by an investigation of potential sex-related differences. Methods: We included 2273 children with overweight/obesity (49.9 % boys) from the UK Millennium Cohort Study. Accelerometer-measured sedentary time (ST) and MVPA were collected at age 7, and behavioral problems were assessed at ages 7 and 11 via the Strengths and Difficulties Questionnaire (SDQ). General linear models were used to examine how ST at 7 years of age was cross-sectionally and longitudinally associated with externalizing and internalizing, while ethnicity, SDQ scores, parental psychological distress, highest parental education, household poverty, and moderate-to-vigorous physical activity (MVPA) were statistically controlled. These analyses are followed by an analysis investigating sex-related differences. Results: In the cross-sectional analyses, more ST was associated with fewer externalizing problems at 7 years among boys (β: −0.008, 95 % CI: −0.013, −0.003) and girls (β: −0.006, 95 % CI: −0.011, −0.001) without controlling for MVPA. More ST at 7 years was associated with fewer externalizing problems (β: −0.010, 95 %CI: −0.015, −0.004) only among boys when adjusting for MVPA. In the longitudinal analysis, more ST at 7 years was associated with fewer externalizing problems at 11 years for boys (β: −0.006, 95 %CI: −0.010, −0.001) and girls (β: −0.007, 95 %CI: −0.012, −0.002) without controlling for MVPA. When adjusting for MVPA at 7 years, more ST at 7 years was associated with fewer externalizing problems at 11 years for girls (β: −0.006, 95 %CI: −0.013, 0.000). Conclusions: In overweight/obese children, device-measured ST at

Monitoring of human serum albumin (HSA) in a point‐of‐care fashion is urgently needed in particular for elderly or chronically ill patients. Herein, a dual‐state emissive chalcone probe having the feature of aggregation‐induced emission was designed and synthesized. The concentration of HSA can be evaluated by the ratios of emission from probes in aggregated and monomeric state, which gives a visually discernible red‐to‐green color change. A simple, portable paper‐based analytical device have been fabricated by integration of the recognition probe in the detection pad and employed for HSA test using the whole blood samples. This paper‐based assay shows the analytical capability comparable to the standard testing methods but is in a point‐of‐care fashion, providing a promising tool for at‐home HSA detection and HSA‐related disease diagnosis.

Spinal cord injury (SCI) is classified as neurological disorder that affects motor and sensory function below the injury level. Studies show that application of low-intensity electrical stimulation (LIES) to neural tissue increases neurochemical factors responsible for regeneration as nerve growth factor. Stem cell (SC) therapy for patients with SCI can result in the replacement of injured neurons after trauma. The electromechanical delay (EMD) is defined as time elapsed between the onset of muscle electrical activation and onset of force production. A dog diagnosed with incomplete thoracolumbar SCI followed by disc hernia between the vertebral segments LI and L2, was evaluated by electromyography and mechanomyography after surgical decompression procedure, one SC transplantation and LIES. We observed motor response and decrease in the EMD from 8.25ms to 5.75ms after the procedures. The wavelet decomposition of EMG signals showed reestablishment of vastus lateralis muscle activity 30 days after the procedure. In addition, the EMG RMS increased from 3.3 µV RMS to 157 µV RMS . The preliminary results of this case report indicate positive effects of the hybrid therapy involving stem cells and low-intensity electrical stimulation after surgical decompression.

Closed loop systems hinge on the accuracy and precision of the continuous glucose monitoring sensors. Most of the commercially available continuous glucose monitoring sensors is implanted subcutaneously for a period of 7-14 days. The subsequent biofouling effects have implications on the performance of the sensors over time especially at low glucose concentrations. In addition, the commercially available sensors are sensitive to the presence of interfering species such as acetaminophen in the skin compartment. We report here on the marriage of minimally invasive, continuous glucose sensors and a direct electron transfer type glucose dehydrogenase enzymatic system. Whilst the microneedles here are designed to sit in the dermal interstitial fluid over a 24-48 hour period to minimize the biofouling effect, the direct electron transfer enzyme allows operation of the electrochemical sensor at lower potentials to minimize the effect of interference. The microneedle structure design also enables the use of compensation electrodes for background subtraction to further nullify the effects of interference.

Chemotherapy, radiotherapy, targeted therapy, and immunotherapy are established cancer treatment modalities that are widely used due to their demonstrated efficacy against tumors and favorable safety profiles or tolerability. Nevertheless, treatment resistance continues to be one of the most pressing unsolved conundrums in cancer treatment. Hypoxia-inducible factors (HIFs) are a family of transcription factors that regulate cellular responses to hypoxia by activating genes involved in various adaptations, including erythropoiesis, glucose metabolism, angiogenesis, cell proliferation, and apoptosis. Despite this critical function, overexpression of HIFs has been observed in numerous cancers, leading to resistance to therapy and disease progression. In recent years, much effort has been poured into developing innovative cancer treatments that target the HIF pathway. Combining HIF inhibitors with current cancer therapies to increase anti-tumor activity and diminish treatment resistance is one strategy for combating therapeutic resistance. This review focuses on how HIF inhibitors could be applied in conjunction with current cancer treatments, including those now being evaluated in clinical trials, to usher in a new era of cancer therapy.
