Bioactivation of the Fungal Phytotoxin 2,5-Anhydro-D-glucitol by Glycolytic Enzymesisan Essential Component of itsMechanism of Action
2002
An isolate of Fusarium solani, NRRL 18883, produces the natural phytotoxin 2,5-anhydro-ᴅ-glucitol (AhG). This fungal metabolite inhibited the growth of roots (I50 of 1.6 mᴍ), butit did nothave any in vitro inhibitory activity. The mechanism of action of AhG requires enzymatic phosphorylation by plant glycolytic kinases to yield AhG-1,6-bisphosphate (AhG-1,6- bisP), an inhibitor of Fru-1,6-bisP aldolase. AhG-1,6-bisP had an I50 value of 570 μᴍ on aldolase activity, and it competed with Fru-1,6-bisP for the catalytic site on the enzyme, with a Ki value of 103 μᴍ. The hydroxyl group on the anomeric carbon of Fru-1,6-bisP is required for the formation of an essential covalent bond to ζ amino fu…
Serum uric acid is not independently associated with plasma renin activity and plasma aldosterone in hypertensive adults
2017
Background and Aims In experimental investigations conducted in rats, raising serum uric acid (SUA) levels resulted in the stimulation of intrarenal renin expression. Studies in humans exploring the association of SUA with plasma renin activity (PRA) yielded conflicting results. Moreover, little is known about the relationship of SUA with plasma aldosterone concentration (PAC). The study aimed to assess the relationship between SUA levels, PRA, and PAC and the influence of age, gender, body mass index (BMI), and hyperuricemia on these relationships in subjects with essential hypertension (EH). Methods and Results We enrolled 372 hypertensive patients (mean age 45 ± 12 years, men 67%) with u…

Stereoselective aldol reaction catalyzed by a highly recyclable polystyrene supported substituted prolinamide catalyst
2008
Polystyrene supported substituted prolinamide was used as catalyst in the aldol reaction between cyclohexanone or acetone and several substituted benzaldehydes in chloroform/water. This catalyst afforded aldol products in high yields and stereoselectivities, especially in the case of reactions performed with acetone. The catalyst was easily recovered by filtration and reused, after regeneration with formic acid, up to 22 times.

Long-Term Calorie Restriction Enhances Cellular Quality-Control Processes in Human Skeletal Muscle
2015
Calorie restriction (CR) retards aging, acts as a hormetic intervention, and increases serum corticosterone and HSP70 expression in rodents. However, less is known regarding the effects of CR on these factors in humans. Serum cortisol and molecular chaperones and autophagic proteins were measured in the skeletal muscle of subjects on CR diets for 3-15 years and in control volunteers. Serum cortisol was higher in the CR group than in age-matched sedentary and endurance athlete groups (15.6 ± 4.6 ng/dl versus 12.3 ± 3.9 ng/dl and 11.2 ± 2.7 ng/dl, respectively; p ≤ 0.001). HSP70, Grp78, beclin-1, and LC3 mRNA and/or protein levels were higher in the skeletal muscle of the CR group compared to…
Ar angiotenzīna sistēmu saistīto antihipertensīvo medikamentu aprite "A Apotheka - 58" 2015.gadā
2016
Hipertensija ir galvenais riska faktors kardiovaskulārām slimībām un smadzeņu infarktam. Viens no veidiem, kā to novērst, ir ar angiotenzīna sistēmu saistīto antihipertensīvu zāļu lietošana. Pie šiem medikamentiem pieder angiotenzīna konvertējošā enzīma inhibitoru (AKEi) un angiotenzīna receptora blokatoru (ARB) saturoši monopreparāti. Bakalaura darba mērķis bija izpētīt dažādu ar angiotenzīna sistēmu saistīto antihipertensīvo medikamentu apriti „A APOTHEKA - 58” 2015. gadā. Par pētījuma metodi autore ir izvēlējusies ārstu izrakstīto recepšu datu apkopošanu par 2015. gadu. Iegūtie dati liecina, ka 2015. gadā pieprasītāki bija AKEi saturoši monopreparāti nekā ARB saturoši monopreparāti. Auto…

Il rumore del tempo e la patina dell'architettura
2014
All’interno del libro che intende essere un contributo su un tema complesso e, forse, tra i più travisati della cultura architettonica come quello dell'architettura mediterranea, si inserisce il saggio “Il rumore del tempo e la patina dell’architettura”. In tale scritto l’autore tratteggia il ruolo del tempo, cronologico ed atmosferico, come uno dei materiali più preziosi dell’architettura. Sciascia entra in argomento ricordando il comportamento sui generis del pittore E. Munch che sottoponeva le sue tele alla cosiddetta “cura da cavalli”, lasciandole esposte alle intemperie perché convinto che i colori si combinassero meglio e conclude riferendosi all’esperienza della casa di Luis Barragán…
