The light-harvesting pigment-protein complex II (LHCII) from plants can be used as a component for biohybrid photovoltaic devices, acting as a photosensitizer to increase the photocurrent generated when devices are illuminated with sunlight. LHCII is effective at photon absorption in the red and blue regions of the visible spectrum, however, it has low absorption in the green region (550-650 nm). Previous studies have shown that synthetic chromophores can be used to fill this spectral gap and transfer additional energy to LHCII, but it was uncertain whether this would translate into an improved performance for photovoltaics.

Method: The procedure consists of bone marrow aspiration, cell separation using an FDA cleared class 2 device, and intravenous and intranasal administration of the stem cell fraction.
Lipoprotein(a) and Atrial Fibrillation: Mechanistic Insights and Therapeutic Approaches.

Elevated lipoprotein(a) [Lp(a)] levels are increasingly recognized as a significant risk factor for cardiovascular diseases and may also contribute to atrial fibrillation (AF). This review investigated the indirect mechanisms through which Lp(a) may influence AF, including proatherogenic, prothrombotic, and proinflammatory pathways. Traditional lipid-lowering therapies, such as lifestyle modifications and statins, have limited effects on Lp(a) levels.

Renal cell carcinoma (RCC) is considered as a "metabolic disease" due to various perturbations in metabolic pathways that could drive cancer development. Glycine decarboxylase (GLDC) is a mitochondrial enzyme that takes part in the oxidation of glycine to support nucleotide biosynthesis via transfer of one-carbon units. Herein, we aimed to investigate the potential role of GLDC in RCC development.

The objective of the present study was to investigate the role and mechanism of bone marrow microenvironmental cells in regulating the mitochondrial mass of leukemia cells, and to uncover the mechanism of leukemia progression at the metabolic level. A mouse model of acute myeloid leukemia (AML) induced by the overexpression of the MLL-AF9 (MA9) fusion protein was established, and the bone marrow cells of AML mice were transplanted into mitochondrial fluorescence reporter mice expressing the Dendra2 protein (mito-Dendra2 mice). The proportion of Dendra2 cells in bone marrow leukemia cells at different stages of AML was quantified by flow cytometry.
