Monitoring Commercial Starter Culture Development in Presence of Red Grape Pomace Powder to Produce Polyphenol-Enriched Fresh Ovine Cheeses at Indust…

2021

Red grape Nero d’Avola cultivar grape pomace powder (GPP) was applied during fresh ovine cheese production in order to increase polyphenol content. Before cheeses were produced, the bacteria of a freeze-dried commercial starter culture were isolated and tested in vitro against GPP. Two dominant strains, both resistant to GPP, were identified. Thestarter culture was inoculated in pasteurized ewe’s milk and the curd was divided into two bulks, one added with 1% (w/w) GPP and another one GPP-free. GPP did not influence the starter culture development, since lactic acid bacteria (LAB) counts were 109 CFU/g in both cheeses at 30 d. To exclude the interference of indigenous LAB, the pasteurized m…

Electrochemical incineration of oxalic acid in the presence of NaCl

2008

Recent researches have demonstrated that electrochemical methods offer an attractive alternative to traditional routes for treating wastewaters containing toxic or/and refractory organic pollutants. The effectiveness of the electrochemical treatment depends on many factors including the presence in solution of specie able to act as mediators. In particular, the effect of chloride ions on the performances of the process has been the object of numerous researches. However, up to now, many practical and theoretical aspects about this argument are not completely clear. In the present work, the anodic incineration of oxalic acid (OA) in the presence of NaCl has been investigated with the aim of …

Oxygen uptake, acid-base balance and hormonal responses in maximal 300 - 400 m running in child, adolescent and adult athletes

2013

Vilmi, Nikke (2013). Oxygen uptake, acid-base balance and hormonal responses in maximal 300 - 400 m running in child, adolescent and adult athletes. Department of Biology of Physical Activity, University of Jyväskylä, Master's thesis, Science of Sport Coaching and Fitness Testing, 55 pp. The 400 m sprint demands both aerobic and anaerobic energy systems. During the race the acid-base balance of the body is disturbed and that has effects on the oxygen uptake. The purpose of this study was to investigate the oxygen uptake and acid-base balance during and after the maximal anaerobic running test in child (300 m), adolescent (350 m) and adult (400 m) athletes. Furthermore, the aim was also to d…

UV filters: From sunscreens to human body and the environment

2007

Recognition of the harmful effects of ultraviolet (UV) radiation on the skin has triggered development of organic chemicals (commonly referred as UV filters) that can absorb UV radiation and attenuate the negative effects of sunlight exposure. Depending on the properties and the intended degree of protection, a wide array of combinations is being marketed as delivering protection against most kinds of UV-induced skin damage. However, some UV filters have dermatological implications, so maximum applicable concentrations have been established. To monitor to what extent commercial products comply with the mandatory limits, several analytical methods have been used for their determination in co…

[60]Fullerene l -Amino Acids and Peptides: Synthesis under Phase-Transfer Catalysis Using a Phosphine–Borane Linker. Electrochemical Behavior

2017

International audience; A new method to link amino acid and peptide derivatives to [60]fullerene is described. It uses hydrophosphination with a secondary phosphine borane. First, the stereoselective synthesis of secondary phosphine borane amino acid derivatives was achieved by alkylation of phenylphosphine borane with gamma-iodo-alpha-amino ester reagents under phase transfer catalysis (PTC). Second, a sec-phosphine borane amino ester was saponified and coupled with alpha,gamma-diamino esters to afford the corresponding dipeptide derivatives in good yields. Finally, the hydrophosphination reaction of [60]fullerene by the sec-phosphine borane compounds was performed under PTC to obtain C-60…

Heterogeneity within and between primary colorectal carcinomas and matched metastases as revealed by analysis of Ki-ras and p53 mutations

2004

Analysis of the genetic status of Ki-ras and p53 in primary colorectal carcinomas and matched colorectal liver metastasis from 30 patients reveals an overall heterogeneity both within and between the two tumoral tissues. Both genes were found mutated with a similar frequency in both tissues; however, identical mutations in primary tumor and matched metastasis were found less frequently in the case of the Ki-ras than the p53 gene. Only in three cases the same p53 and Ki-ras mutations found in the primary tumor were found also in the metastasis. In several metastatic specimens the DNA bearing a mutation detected also in the primary tumor appears significantly less abundant than the wild-type …

UV-B exposure causes DNA damage and changes in protein expression in northern pike (Esox lucius) posthatched embryos.

2012

The ongoing anthropogenically caused ozone depletion and climate change has increased the amount of biologically harmful UV-B radiation, which is detrimental to fish in embryonal stages. The effects of UV-B radiation on the levels and locations of DNA damage manifested as cyclobutane pyrimidine dimers (CPDs), heat shock protein 70 (HSP70) and p53 protein in newly hatched embryos of pike were examined. Pike larvae were exposed in the laboratory to current and enhanced doses of UV-B radiation. UV-B exposure caused the formation of CPDs in a fluence rate-dependent manner, and the CPDs were found deeper in the tissues with increasing fluence rates. UV-B radiation induced HSP70 in epidermis, and…

2020

La toxicidad en la piel es uno de los efectos perjudiciales más comunes de los taxanos. El objetivo fue evaluar el efecto del fármaco paclitaxel sobre la piel en un grupo de pacientes con cáncer ginecológico, y en un modelo 3D in vitro de piel, así como en melanocitos, queratinocitos, fibroblastos y en células microvasculares dérmicas humanas. En el estudio in vivo se realizaron las medidas en una población control de mujeres sanas (n=20) y una población de pacientes con tumores ginecológicos en tratamiento con paclitaxel (n=20), antes, durante y después. Las diferentes determinaciones fueron el valor de hidratación, la TEWL, el valor de sebo, valores de pigmentación y eritema, valores de e…
