The kinases AMPK, and mTOR as part of either mTORC1 or mTORC2, are major orchestrators of cellular growth and metabolism. Phosphorylation of mTOR Ser1261 is reportedly stimulated by both insulin and AMPK activation and a regulator of both mTORC1 and mTORC2 activity. Intrigued by the possibilities that Ser1261 might be a convergence point between insulin and AMPK signaling in skeletal muscle, we investigated the regulation and function of this site using a combination of human exercise, transgenic mouse, and cell culture models.

The use of 3D-printed electrodes is reported fabricated from in-house conductive filament composed of a mixture of recycled poly (lactic acid) (rPLA), graphite (Gpt), and carbon black (CB) for fast detection of the abused drug ketamine. Firstly, the performance of these electrodes was evaluated in comparison to 3D-printed electrodes produced employing a commercially available conductive filament. After a simple pretreatment step (mechanical polishing), the new 3D-printed electrodes presented better performance than the electrodes produced from commercial filament in relation to peak-to-peak separation of the redox probe [Fe(CN)]/ (130 mV and 759 mV, respectively), charge transfer resistance (R = 1.

Article Synopsis
  • Metabolic flexibility in skeletal muscle is crucial for healthy glucose and lipid metabolism, and its dysfunction can lead to metabolic diseases.
  • Exercise improves metabolic flexibility and helps identify mechanisms that support metabolic health.
  • The study reveals that pantothenate kinase 4 (PanK4) is vital for muscle metabolism, as its deletion disrupts fatty acid oxidation and elevates harmful acetyl-CoA levels, which lead to glucose intolerance, while increasing PanK4 enhances glucose uptake and lowers acetyl-CoA.

Babassu (Atallea sp.), a native palm tree from South America's Amazon produces bio-oil and biochar with significant potential for industrial applications. Babassu oil as a bio-based plasticizer is reported here for the first time to replace petrochemical alternatives in the production of conductive filaments for additive manufacturing purposes.

The Transplant Evaluation Rating Scale (TERS) assesses the psychosocial risk of transplant candidates; however, its predictive value for outcomes in living-donor kidney transplant (LDKT) recipients remains unclear. This study evaluated the predictive power of the TERS for psychosocial outcomes in LDKT recipients over two years post-transplant. In this prospective single-center cohort study, 107 LDKT recipients completed assessments pre-transplant (T0), 6 months post-transplant (T1), and 24 months post-transplant (T2).
