Vanillin Suppresses Metastatic Potential of Human Cancer Cells through PI3K Inhibition and Decreases Angiogenesis in Vivo
2009
Vanillin, a food flavoring agent, has been shown to suppress cancer cell migration and metastasis in a mouse model, but its mechanism of action is unknown. In this report, we have examined the antimetastatic potential of vanillin and its structurally related compounds, vanillic acid, vanillyl alcohol, and apocynin on hepatocyte growth factor (HGF)-induced migration of human lung cancer cells by the Transwell assay. Vanillin and apocynin could inhibit cell migration, and both compounds selectively inhibited Akt phosphorylation of HGF signaling, without affecting phosphorylation of Met and Erk. Vanillin and apocynin could inhibit the enzymatic activity of phosphoinositide 3-kinase (PI3K), as …
TLR4 elimination prevents synaptic and myelin alterations and long-term cognitive dysfunctions in adolescent mice with intermittent ethanol treatment.
2015
The adolescent brain undergoes important dynamic and plastic cell changes, including overproduction of axons and synapses, followed by rapid pruning along with ongoing axon myelination. These developmental changes make the adolescent brain particularly vulnerable to neurotoxic and behavioral effects of alcohol. Although the mechanisms of these effects are largely unknown, we demonstrated that ethanol by activating innate immune receptors toll-like receptor 4 (TLR4), induces neuroinflammation and brain damage in adult mice. The present study aims to evaluate whether intermittent ethanol treatment in adolescence promotes TLR4-dependent pro-inflammatory processes, leading to myelin and synapti…
Extracellular oxidoreduction potential modifies carbon and electron flow in Escherichia coli.
2000
ABSTRACT Wild-type Escherichia coli K-12 ferments glucose to a mixture of ethanol and acetic, lactic, formic, and succinic acids. In anoxic chemostat culture at four dilution rates and two different oxidoreduction potentials (ORP), this strain generated a spectrum of products which depended on ORP. Whatever the dilution rate tested, in low reducing conditions (−100 mV), the production of formate, acetate, ethanol, and lactate was in molar proportions of approximately 2.5:1:1:0.3, and in high reducing conditions (−320 mV), the production was in molar proportions of 2:0.6:1:2. The modification of metabolic fluxes was due to an ORP effect on the synthesis or stability of some fermentation enzy…
Akūta alkohola hepatīta klīniskā norise un iznākumi
2015
Diplomdarba tēma. Akūta alkohola hepatīta klīniskā norise un iznākumi. Ievads. Alkohola hepatīts ir klīnisks sindroms, ko izraisa hroniska alkohola lietošana. Akūts alkohola hepatīts vienmēr attīstās uz jau esoša hroniska alkohola aknu bojājuma fona – taukainās hepatozes, steatohepatīta, fibrozes vai cirozes. Agrīna mirstība no alkohola hepatīta variē pēc slimības smaguma no 20% vieglām formām līdz 30-60% smagām formām. Darba mērķis. Pacientiem ar akūtu alkohola hepatītu noteikt un salīdzināt prognostiskos rādītājus pēc Maddrey un MELD aprēķiniem, kas ļautu prognozēt slimības attīstības tendenci un iznākumu pirmreizēji stacionētiem, atkārtoti stacionētiem un mirušiem pacientiem Latvijā.

Convergent synthesis and preliminary biological evaluations of the stilbenolignan (±)-aiphanol and various congeners
2003
Treatment of an equimolar mixture of stilbene 7 and cinnamyl alcohol 8 with silver carbonate in acetone–benzene afforded a ca. 2 : 1 : 2 : 1 mixture of the stilbenolignan (±)-aiphanol (1) and congeners 2–4 each of which show significant anti-angiogenic and COX-2 inhibitory properties.
From strong to fragile glass formers: secondary relaxation in polyalcohols.
2002
We have studied details of the molecular origin of slow secondary relaxation near T(g) in a series of neat polyalcohols by means of dielectric spectroscopy and (2)H NMR. From glycerol to threitol, xylitol, and sorbitol the appearance of the secondary relaxation changes gradually from a wing-type scenario to a pronounced beta peak. It is found that in sorbitol the dynamics of the whole molecule contributes equally to the beta process, while in glycerol the hydrogen bond forming OH groups remain rather rigid compared to the hydrogens bonded to the carbon skeleton.
Transgresión moral, enfermedad y salud holística en la Misión Livingstonia en Malawi a finales del siglo XIX y principios del siglo XX
2009
This article examines ideas of morality and health, and connections between moral transgression and disease in both Scottish missionary and Central African thought in the context of the Livingstonia Mission of the Presbyterian Free Church of Scotland in Malawi during the late nineteenth and early twentieth centuries.2 By concentrating on debates, conflicts and co-operation between missionaries and Africans over the key issues of beer drinking and sexual morality, this article explores the emergence of a new ‘moral hygiene’ among African Christian communities in Northern Malawi.

Alcoholic Beverage and Meal Choices for the Prevention of Noncommunicable Diseases: A Randomized Nutrigenomic Trial
2018
Background. Noncommunicable diseases (NCDs) are the first cause of death worldwide. Mediterranean diet may play a crucial role in the prevention of NCDs, and the presence of wine in this diet could play a positive role on health. Methods. 54 healthy volunteers consumed one of the following beverages: red (RW) or white wine (WW), vodka (VDK), and/or Mediterranean meal (MeDM) and high-fat meal (HFM). Results. OxLDL-C changed significantly between baseline versus HFM, MeDM versus HFM, and HFM versus HFM + RW (p<0.05). Significant upregulation of catalase (CAT) was observed only after RW. Conversely, WW, VDK, RW + MeDM, HF + WW, and HF + VDK determined a significant downregulation of CAT gen…
