OXIDASES ACTIVITIES AND ANTIOXIDANT CAPACITY OF MINIMALLY PROCESSED BABY ROMAINE LETTUCE (Lactuca sativa L. CV. DUENDE) CULTIVATED UNDER DIFFERENT SA…

[SPA] El pardeamiento enzimático es uno de los principales problemas implicados en el procesamiento mínimo y en la siguiente conservación de hortalizas de hoja, reduciendo la vida comercial del producto. Se han evaluado las variaciones de las dos principales oxidasas, polifenol oxidasa (PPO) y peroxidasa (POD), así como del contenido en fenoles, del color y de la capacidad antioxidante (metodo ORAC) durante 10 días de conservación a 4 °C de lechuga Baby Romaine (Lactuca sativa L. cv. Duende) mínimamente procesada, cultivada bajo 3 distintas condiciones de salinidad (2,8, 3,8, 4,8 dS/m), para determinar la condición más apta al siguiente procesamiento. Niveles crecientes de salinidad redujer…

Is the host or the parasite the most locally adapted in an amphipod–acanthocephalan relationship? A case study in a biological invasion context

2007

8 pages; International audience; Manipulative endoparasites with complex life cycles can alter their intermediate host immunity and behaviour in ways that increase survival probability within the host body cavity and enhance successful transmission to the definitive host. These parasitic manipulations are variable among and within parasite species and may result from co-evolutionary processes, in which the parasite is constrained for adaptation to the local intermediate host. Hence, arrival of a new host species in a local host population may promote local parasite maladaptation. This study tested the occurrence of local adaptation in two distantly located populations of the acanthocephalan…

Enzyme replacement therapy with agalsidase alfa in pregnant women with Fabry disease

2009

A family with various symptomatology suggestive of Anderson-Fabry disease and a genetic polymorphism of alpha galactosidase A gene.

2014

Background: Anderson/Fabry disease expresses a wide range of clinical variability in patients that it is possible to explain referring to a genetic variability with numerous mutations described in the literature (more than 600). Methods: We report some clinical cases of some members of a Sicilian family to express phenotypical variability of this disease in subjects with the same genetic mutation. Results: The first case was a 59-year-old female. Brain MRI revealed right frontal periventricular white matter of likely vascular-degenerative origin. The proband's alpha galactosidase A activity was 3.7. nmol/mL/h. Molecular genetics revealed a polymorphism: - 10 C. >. T; IVS 2-76_80del5; IVS…

Additive effect of mutations in LDLR and PCSK9 genes on the phenotype of familial hypercholesterolemia.

2006

Patients homozygous or Compound heterozygous for LDLR mutations or double heterozygous for LDLR and apo B R3500Q mutation have higher LDL-C levels. more extensive xanthomatosis and more severe premature coronary disease (pCAD) than simple heterozygotes for mutations in either these genes or for missense mutations in PCSK9 gene. It is not known whether combined mutations in LDLR and PKCS9 are associated with such a severe phenotype. We sequenced Apo B and PCSK9 genes in two patients with the clinical diagnosis of homozygous FH who were heterozygous for LDLR gene mutations. Proband Z.P. (LDL-C 13.39 mmol/L and pCAD) was heterozygous for an LDLR mutation (p.E228K) inherited from her father (LD…

Genotype–phenotype correlation in a new Fabry-disease-causing mutation

2019

Background: Fabry disease (FD) is a rare X-linked inherited lysosomal storage disorder caused by α-galactosidase A deficiency leading to intracellular glycosphingolipid accumulation. FD manifestation is multisystem, and can differ depending on disease-related genetic variants. Currently, more than 700 different FD-causing mutations have been identified in the human GLA gene. We identified a novel mutation in a Lithuanian family with classical manifestations of Fabry disease, revealing severe effects to the cardiovascular systems of heterozygous women. Case presentation: A 49-year-old woman underwent echocardiography due to progressive dyspnea that lasted seven years, reduced physical a…

Incretin-Based Therapies Role in COVID-19 Era: Evolving Insights

2020

The current coronavirus disease 2019 (COVID-19) pandemic has led the scientific community to breach new frontiers in the understanding of human physiology and disease pathogenesis. It has been hypothesized that the human dipeptidyl peptidase 4 (DPP4) enzyme receptor may be a functional target for the spike proteins of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2). Since DPP4-inhibitors are currently used for the treatment of patients with type-2 diabetes (T2DM), there is currently high interest in the possibility that these agents, or incretin-based therapies (IBTs) in general, may be of benefit against the new coronavirus infection. Diabetes is associated with increased COV…

Antitumor effects of dehydroxymethylepoxyquinomicin, a novel nuclear factor-kappaB inhibitor, in human liver cancer cells are mediated through a reac…

2009

Activation of the nuclear transcription factor-kappa B (NF-kappa B) has been implicated in liver tumorigenesis. We evaluated the effects of a novel NF-kappa B inhibitor, dehydroxymethylepoxyquinomicin (DHMEQ), in two human liver cancer cell lines HA22T/VGH and HuH-6. DHMEQ treatment dose dependently decreased the DNA-binding capacity of the NF-kappa B p65 subunit, inhibited cell growth and proliferation, and increased apoptosis as shown by caspase activation, release of cytochrome c, poly(ADP-ribose) polymerase cleavage, and down-regulation of survivin. DHMEQ also induced a dose-dependent activation of mitogen-activated protein kinase kinase/extracellular signal-regulated kinase signaling, …
