BACKGROUND Littoral cell angioma (LCA) is a rare vascular tumor of the spleen. Generally thought to be benign, additional cases of LCA with malignant features have been described. Thus, its malignant potential seems to vary and must be considered uncertain. The etiology remains unclear, but an immune dysregulation for the apparent association with malignancies of visceral organs or immune-media...

PURPOSE Leber congenital amaurosis (LCA) is the most severe inherited retinopathy with the earliest age of onset. To date, eleven genes have been reported to cause the non-syndromic LCA phenotype. The CEP290 gene has been shown to account for Joubert and Senior-Loken syndromes and to represent a frequent cause of non-syndromic LCA. The aim of the present study was to establish the prevalence of...

CONTEXT Laparoscopic cryoablation (LCA) and percutaneous cryoablation(PCA) have been used on patients with small renal masses(SRMs) for many years. However, clinical studies assessing their feasibility and safety have reported contradictory outcomes. This systematic evaluation was performed to obtain comprehensive evidence with regard to the feasibility and safety of PCA compared with LCA. ME...

Intracellular calcification of coccolithophores generates CO₂ and consumes additional energy for acquisition of calcium and bicarbonate ions; therefore, it may correlate with photoprotective processes by influencing the energetics. To address this hypothesis, a calcifying Emiliania huxleyi strain (CS-369) was grown semi-continuously at reduced (0.1 mM, LCa) and ambient Ca²⁺ concentrations (10 m...

Previously, a partial-length cDNA and a complete genomic clone encoding a putative sarcoplasmic reticulum-type Ca2+-ATPase (LCA, Lycopersicon Ca2+-ATPase) were isolated from tomato. To determine the subcellular localization of this Ca2+-ATPase, specific polyclonal antibodies raised against a fusion protein encoding a portion of the LCA polypeptide were generated. Based on hybridization of the L...

Leber Congenital Amaurosis (LCA), the most severe inherited retinal dystrophy, is genetically heterogeneous, with 14 genes accounting for 70% of patients. Here, 91 LCA probands underwent LCA chip analysis and subsequent sequencing of 6 genes (CEP290, CRB1, RPE65, GUCY2D, AIPL1and CRX), revealing mutations in 69% of the cohort, with major involvement of CEP290 (30%). In addition, 11 patients wit...

Life Cycle Assessment (LCA) has gained attention because it enables quantitative evaluation of the burden a product places on the environment. However, acceptance of LCA has proceeded slowly because a large amount of work is required to gather the environmental burden data used in the evaluation. To shorten this work time, we utilize readily-accessible databases both internal and external to th...

Life cycle assessment (LCA) has a number of defining characteristics that enables it to address questions that no other assessment tools can address. This chapter begins by demonstrating how the use of LCA in the late 2000s led to a drastic shift in the dominant perception that biofuels were “green”, “sustainable” or “carbon neutral”, which led to a change in biofuel policies. This is followed ...
