Objective: Psoriasis is associated with a high prevalence of metabolic syndrome (MS), and patients with concomitant psoriasis and MS are more severely affected and less responsive to treatment. However, the molecular mechanisms behind these effects are unknown. Recent studies have shown that leptin may serve as a molecular link between psoriasis and MS, suggesting that high leptin concentrations may exacerbate psoriasis. However, the molecular mechanism of this effect is still unclear. We aimed to investigate the effect of leptin on autophagy in patients with psoriasis. Methods: From January 2021 to June 2022 in PLA General Hospital, we enrolled 51 patients with psoriasis, including 21 patients with MS and 30 without MS, and 30 healthy controls who had undergone nevus surgery. We measured the epidermal leptin, P62, and Lc.b.concentrations of patients by immunohistochemistry, and measured the serum leptin concentration by enzyme-linked immunosorbent assay. We then performed correlation analyses to compare these proteins' concentrations between patients with concomitant psoriasis and MS, patients with psoriasis alone, and healthy control groups. Additionally, we performed western blotting after in vitro culture of HacaT cells with different concentrations of leptin and measured the expression levels of the autophagy markers beclin1, Lc.b. and P62; the differentiation markers K10, K16, and K17; and PI3K/AKT/mTOR signaling pathway-related proteins of Hacat cells. Next, we transfected ATG5 into HacaT cells to revert autophagy and used the specific PI3K inhibitor LY294002 to block PI3K/AKT/mTOR signaling. The expression levels of K10, K16, and K17 of Hacat cells were again measured. One-way analysis of variance was used for the comparison of means of multiple samples, and LSD-t post hoc test was used for comparison between the 2 groups. The counting data were analyzed by the chi-square test. correlations were evaluated by Pearson correlation analysis. Results: The serum l

The development, production and utilization of renewable energy, energy storage and green hydrogen and the associated technologies in Sri Lanka have great potential to contribute to the United Nations' Sustainable Development Goals (SDGs). The island aims to achieve 70% electricity generation from renewable energy sources by 2030 (within the target of 40% utilization of renewable energy sources for the entire energy generation of the country by 2030). The power sector has to invest US$11 billion from 2023 to 2030 to contribute to reaching this target. This commentary aims to provide a critical perspective on the recommendations of the report from the National Science and Technology commission's 9th biennial conference in 2023 on science and technology, the sub-thematic technical report on clean energy, energy storage and green hydrogen in line with the SDGs in the Sri Lankan context. The technical report provides insightful recommendations for Sri Lanka's energy sector under three main sections: renewable energy, energy storage and green hydrogen. Also, it explores the potential of various renewable energy sources, energy storage systems and green hydrogen as sustainable solutions to address the country's energy challenges while emphasizing the spillover effects of them, which could contribute to the enterprise's job creation and uplift the economy. This commentary provides a critical perspective on clean energy, energy storage and green hydrogen in line with the United Nations SDGs in the Sri Lankan context based on a recent report from the National Science and Technology commission of Sri Lanka.
