The association of congenital diaphragmatic hernia with scoliosis.

Purpose: To determine the prevalence of scoliosis in patients who have undergone surgical repair of CDH and attempt to assess the aetiology of scoliosis in affected cases.

Methods: A prospectively collected database of patients with CDH treated in a single centre between 1997 and 2023 was reviewed. Cases with adequate records who continued to reside locally having survived beyond age 2 and > 2 years following CDH repair were included.

One-step growth of thin film SnS with large grains using MOCVD.

Thin film tin sulphide (SnS) films were produced with grain sizes greater than 1 μm using a one-step metal organic chemical vapour deposition process. Tin-doped indium oxide (ITO) was used as the substrate, having a similar work function to molybdenum typically used as the back contact, but with potential use of its transparency for bifacial illumination. Tetraethyltin and ditertiarybutylsulphide were used as precursors with process temperatures 430-470 °C to promote film growth with large grains.

Bace1-dependent amyloid processing regulates hypothalamic leptin sensitivity in obese mice.

Obesity places an enormous medical and economic burden on society. The principal driver appears to be central leptin resistance with hyperleptinemia. Accordingly, a compound that reverses or prevents leptin resistance should promote weight normalisation and improve glucose homeostasis.

Implications of the negative capacitance observed at forward bias in nanocomposite and polycrystalline solar cells.

Four different types of solar cells prepared in different laboratories have been characterized by impedance spectroscopy (IS): thin-film CdS/CdTe devices, an extremely thin absorber (eta) solar cell made with microporous TiO2/In(OH)xSy/PbS/PEDOT, an eta-solar cell of nanowire ZnO/CdSe/CuSCN, and a solid-state dye-sensitized solar cell (DSSC) with Spiro-OMeTAD as the transparent hole conductor. A negative capacitance behavior has been observed in all of them at high forward bias, independent of material type (organic and inorganic), configuration, and geometry of the cells studied. The experiments suggest a universality of the underlying phenomenon giving rise to this effect in a broad range of solar cell devices.
