Corrosion of stainless steel in food and pharmaceutical industry
2021
Abstract Stainless steels are widely used in the food and pharmaceutical industry because of their high corrosion resistance and superior mechanical properties. These features are crucial because produced foodstuffs and drugs must comply with high purity and quality standards. Just a proper selection of stainless steel grade can prevent corrosion phenomena that can be detrimental to the whole manufacturing process. Food/drugs production process phases will be here analyzed and discussed with a particular emphasis on the possible corrosion mechanism of stainless steels in those particular operating conditions. Recent advances on the methods to assess corrosion of stainless steels in food and…

The oral KIF11 inhibitor 4SC‐205 exhibits antitumor activity and potentiates standard and targeted therapies in primary and metastatic neuroblastoma …
2021
Inhibidor de KIF11; Terapias dirigidas; Metástasis Inhibidor de KIF11; Teràpies dirigides; Metàstasi KIF11 inhibitor; Targeted therapies; Metastasis In summary, our study provides a rationale for the future therapeutic integration in clinical trials of 4SC-205, an structurally distinct oral KIF11 inhibitor that shows potent antitumor activity in multiple preclinical neuroblastoma models and sensitizes neuroblastoma cells to standard chemotherapy and specific neuroblastoma-targeted therapies. The financial support for this research was provided by Instituto de Salud Calos III (PI20/00530 to Miguel F. Segura; PI20/01107 to Rosa Noguera; PI17/02248 and CPII18/00027 to Anna Santamaria; PI19/013…
The debate on rare diseases : a look at media response
2015
Este artículo se encuentra disponible en la siguiente URL: https://ojs.uv.es/index.php/Metode/article/view/7188/7809 Este monográfico lleva por título "Science grid : the public understanding of science". Rare diseases (RDs) are those that affect fewer than five people in every 10,000. There are around 7,000 RDs, they are difficult to diagnose and very few have a treatment. This article explores how the media report on the arguments and counter-arguments regarding the access to drugs for these pathologies, with critical discourse analysis for the case of Duchenne muscular dystrophy. We concluded that, in times of crisis, the debate polarises around economic arguments (the price of drugs), r…

Saving the pharmacy of the sea: How does global change affect species with bioactive potential in the Mediterranean?
2020
Several marine species in the Mediterranean produce molecules with bioactive potential that could be used to develop new drugs (antibiotics, antifungals, antivirals, and antitumourals). Different human activities such as pollution, marine recreation, and fishing, as well as climate change, threaten and even endanger some of these species. These vulnerable species with bioactive potential must be protected, especially in marine reserves, not only because they are valuable components of marine ecosystems, but also because they are a potential source of molecules with pharmacological properties that are currently being researched for the creation of new drugs.
Synthesis and analysis of activity of a potential anti-melanoma prodrug with a hydrazine linker
2013
A potential anti-melanoma prodrug containing a phenolic activator, a hydrazine linker, and a nitrogen mustard effector - (N-{4-[bis-(2-chloroethyl)amino]benzoyl}-N'-(4-hydroxybenzyl)hydrazine) has been synthesized in seven steps. Spectrophotometric measurements of its oxidation by tyrosinase showed a rapid increase of absorbance at 337 nm. HPLC analysis demonstrated that two major products were formed. However, during the reaction one of the products was converted into the other. The stable product with a maximum of absorption at 337 nm was isolated and identified as 5,6-dihydroxy-1H-indazol-1-yl 4-[bis-(2-chloroethyl)amino]benzoate. It was formed by a cyclization of the enzymatically gener…
Role of serotonin in central dopamine dysfunction
2010
The interaction between serotonin (5-HT) and dopamine (DA)-containing neurons in the brain is a research topic that has raised the interest of many scientists working in the field of neuroscience since the first demonstration of the presence of monoamine-containing neurons in the mid 1960. The bulk of neuroanatomical data available clearly indicate that DA-containing neurons in the brain receive a prominent innervation from serotonin (5-hydroxytryptamine, 5-HT) originating in the raphe nuclei of the brainstem. Compelling electrophysiological and neurochemical data show that 5-HT can exert complex effects on the activity of midbrain DA neurons mediated by its various receptor subtypes. The m…
Metabolism of third generation synthetic cannabinoids using zebrafish larvae.
2021
Synthetic cannabinoids are the second largest group of new psychoactive substances reported by the United Nations Office on Drugs and Crime in the last decade and case reports bring attention to its high potency effects and its severe toxicity, including fatalities. Moreover, synthetic cannabinoids are usually entirely metabolized and metabolic pathways for many new generation synthetic cannabinoids are still unknown. In this study, the metabolism of five third generation synthetic cannabinoids were evaluated using zebrafish (Danio rerio) larvae as 24-hours in vivo model studied within 5 days after fertilization. The studied synthetic cannabinoids were MMB-CHMICA, ADB-CHMICA, ADB-CHMINACA, …
Metal drugs and the anticancer immune response
2018
The immune system deploys a multitude of innate and adaptive mechanisms not only to ward off pathogens but also to prevent malignant transformation ("immune surveillance"). Hence, a clinically apparent tumor already reflects selection for those malignant cell clones capable of evading immune recognition ("immune evasion"). Metal drugs, besides their well-investigated cytotoxic anticancer effects, massively interact with the cancer-immune interface and can reverse important aspects of immune evasion. This topic has recently gained intense attention based on combination approaches with anticancer immunotherapy (e.g., immune checkpoint inhibitors), a strategy recently delivering first exciting…
