The Relationship Between a Baby's Age and Sleepiness in a Sample of Mothers
2021
One question of great practical importance for the parents, and especially the mother, after the birth of a baby, refers to how long the time during which they have to go with less and more fragmented sleep actually lasts. Most of the studies only explore this issue up to 6 months of the newborn's life, and less is known about the sleep problems the mothers may have after this initial period. The objective of this study is to examine the relationship between the sleep disruption and daytime sleepiness of mothers with infants until 2 years old compared to a group of women currently not at care of babies. To this end, a sample of 113 women, 67 currently bringing up a baby of under 2 years old…
Pesticide residues in Lake Albufera, Valencia, Spain.
1987
Abstract Analysis of water samples from the lake in Albufera, Valencia, indicates that the pesticides molinate, benthiocarb, and fenitrothion do not reach levels that are lethal to fish.
Interactions of benzodiazepines with human serum albumin. Circular dichroism studies.
1973
The circular dichroism spectra of 12 benzodiazepine derivatives studied in presence of human serum albumin are presented. Nearly all substances give biphasic extrinsic Cotton effects. At the CD maxima the molar ellipticities and the anisotropy factors are calculated. The influence of the chemical structure of the benzodiazepines on the induced Cotton effect is discussed. There is a linear correlation between the anisotropy factors and the logarithms of the partition coefficients of the substances. It is suggested that the phenyl ring of the benzodiazepine molecule is one of the essential groups for the binding of these substances to human serum albumin.
Insight on pyrimido[5,4-g]indolizine and pyrimido[4,5-c]pyrrolo[1,2-a]azepine systems as promising photosensitizers on malignant cells
2022
Searching for new small molecules as photosensitizing agents, we have developed a class of twenty-five pyrimido[5,4-g]indolizine and pyrimido[4,5-c]pyrrolo[1,2-a]azepines with a good substitution pattern defining a versatile synthetic pathway to approach the title ring system. All compounds were evaluated for their photocytotoxicity on a triple negative human breast cancer cell line (MDA-MB-231) in the dark and under UVA light (2.0 J/cm2). The most effective compounds exhibited a photoantiproliferative activity with IC50 values up to nanomolar ranges. Interestingly, these new developed compounds showed high selectivity towards cancerous cells with respect to non-cancerous ones. Moreover, fo…
The Philippines 2017 : Duterte-led Authoritarian Populism and Its Liberal-Democratic Roots
2017
Philippine President Rodrigo Duterte led a phenomenal campaign to win the 2016 national election. During his first two years in power Duterte has become the protagonist and exemplar of a key new development – the social formation of a regime of authoritarian populism. Based on an analysis of news reports, public debates, survey results, and official policy documents from 2017, the article examines various features of this emergent regime and then illuminates the historical-institutional mechanisms that brought it about. The inquiry is predicated on an understanding that the old EDSA Republic’s liberal-democratic regime has been marked by intractable socio-economic crises since its installat…
La vida cotidiana de los vecinos de Manila a través de sus testamentos e inventarios de bienes
2019
With the general objective indicated in its title, this work tries to highlight relevant aspects in the continuity of the Spanish domain in the Philippines, dependent on the maintenance of the Spanish capital. The inevitable selection of topics has lead the preferences of this work towards the residents collaboration to defend the city, the conversion of many of them into traders of exotic products and singular slaves owners, and their collaboration to an incredible miscegenation due to the ethnic variety. On the other hand, to follow the footsteps of the first generation of residents in Manila, at the end of the 16th century and during the 17th century, this work gives us some information …

Presynaptic regulation of the electrically evoked release of endogenous dopamine from the isolated neurointermediate lobe or isolated neural lobe of …
1988
Isolated neurointermediate lobes (NILs) or isolated neural lobes (NLs) of the rat pituitary gland were incubated in Krebs-HEPES solution which contained pargyline and the dopamine uptake inhibitor GBR 12921. The release of endogenous dopamine was determined by HPLC with electrochemical detection. Electrical stimulation of the pituitary stalk induced a frequency-dependent release of dopamine. The release of dopamine from the combined NIL evoked by stimulation at 15 Hz was increased by 130% in the presence of the dopamine D2 receptor antagonist, (-)-sulpiride; the (+)-enantiomer of sulpiride had virtually no effect. When the stimulation frequency was 3 Hz (-)-sulpiride caused an increase in d…
Sumatriptan Succinate Transdermal Delivery Systems for The Treatment of Migraine
2007
We have successfully obtained sumatriptan transdermal systems with different polymer compositions: methyl cellulose (MC), polyvinyl pyrrolidone (PVP) and a polyvinyl pyrrolidone (PVP)-polyvinyl alcohol (PVA) mixture. The systems contained 1,2-propylenglycol (MC) or sorbitol as a plasticizer (PVP and PVP-PVA), methacrylate copolymer as an adhesive agent, and an occlusive liner. Azone (5%, w/w) was incorporated into all the systems as a percutaneous enhancer. Transdermal systems are thin, transparent and non-adhesive when in a dry state. The permeation of sumatriptan succinate across pig ear skin was studied using the systems prepared. The formulation with MC polymer produced a statistically …
