Virological efficacy and emergence of drug resistance in adults on antiretroviral treatment in rural Tanzania
2009
Background Virological response to antiretroviral treatment (ART) in rural Africa is poorly described. We examined virological efficacy and emergence of drug resistance in adults receiving first-line ART for up to 4 years in rural Tanzania. Methods Haydom Lutheran Hospital has provided ART to HIV-infected patients since October 2003. A combination of stavudine or zidovudine with lamivudine and either nevirapine or efavirenz is the standard first-line regimen. Nested in a longitudinal cohort study of patients consecutively starting ART, we carried out a cross-sectional virological efficacy survey between November 2007 and June 2008. HIV viral load was measured in all adults who had completed…
Effects of ageing on peroxidase activity and localization in radish (Raphanus sativus L.) seeds.
2010
Peroxidase activity was assayed in crude extracts of integument, cotyledons and embryo axis of radish seeds, deteriorated under accelerated ageing conditions. Over five days of ageing, in which germination decreased from 100 to 52%, the enzyme activity in integument was higher than that in other seed parts, increasing in the first days of ageing and then decreasing sharply in extremely aged seeds. Polyacrylamide gel electrophoresis analysis showed four peroxidase isoenzymes with MM of 98, 52.5, 32.8 and 29.5 kDa in the embryo axis of unaged seeds, and only the 32.8 and 29.5 kDa MM isoforms in the integument and cotyledons. In these parts of the seed, only the 29.5 kDa MM isoenzyme increased…
Data from: Effects of undergrowth removal and edge proximity on ground beetles and vascular plants in urban boreal forests
2019
Urban forests are regularly managed for human safety and aesthetic reasons, but they are crucial habitat for many species. Removals of undergrowth occur commonly in these forests, yet the ecological consequences of these operations are poorly understood. We sampled ground beetles (Coleoptera, Carabidae) and vascular plants along 20-m edge gradients in Finnish urban forests, in five stands treated 0.5−2.5 years earlier with undergrowth removal and in five untreated stands. We hypothesized that undergrowth removal and edge proximity would benefit opportunistic and open-habitat species, whereas shady-habitat species would be affected negatively. (1) Regarding carabids, diversity and evenness i…

Effetti della concimazione sulla qualità dell'aglio coltivato in Sicilia. Effects of fertilization on the quality of garlic grown in Sicily.
2010
In order to expand this crop and to improve bulbs quality a study was carried out to evaluate different fertilization techniques. Four fertilization formulas were evaluated: 1) mineral fertilization commonly used by Paceco producers - pre-planting with 55, 110 and 80 kg ha-1 of N, P2O5 and K2O - post planting with 47 and 46 kg ha-1 of N and K2O; 2) organic fertilization with an organic mix - pre-planting with 320 and 240 kg ha-1 of N and P2O5; 3) mineral fertilization - pre-planting with 40, 70 and 100 kg ha-1 of N, P2O5 and K2O - post-planting with 80 kg ha-1 of N half at 3-4 leaves and half at bulbs formation; 4) only post-planting fertilization with 52 and 184 kg ha-1 of N and K2O, half …

Profile of leukocyte-endothelial cell interactions induced in venules and arterioles by nucleoside reverse-transcriptase inhibitors in vivo.
2013
Background There is controversy regarding cardiovascular (CV) toxicity of the nucleoside reverse-transcriptase inhibitors used to treat human immunodeficiency virus infection. Methods We evaluated the effects of nucleoside reverse-transcriptase inhibitors on leukocyte-endothelium interactions, a hallmark of CV diseases, in rat mesenteric vessels using intravital microscopy and in human arterial cells using a flow chamber system. Results Abacavir and didanosine increased rolling, adhesion and emigration in rat vessels. These effects were reversed with antibodies against Macrophage-1 antigen (Mac-1) or intercellular adhesion molecule 1 and were reproduced in human cells. Lamivudine, zidovudin…

Toxicological and bioactivity evaluation of blackcurrant press cake, sea buckthorn leaves and bark from Scots pine and Norway spruce extracts under a…
2021
Aqueous extracts from blackcurrant press cake (BC), Norway spruce bark (NS), Scots pine bark (SP), and sea buckthorn leaves (SB) were obtained using maceration and pressurized hot water and tested for their bioactivities. Maceration provided the extraction of higher dry matter contents, including total phenolics (TPC), anthocyanins, and condensed tannins, which also impacted higher antioxidant activity. NS and SB extracts presented the highest mean values of TPC and antioxidant activity. Individually, NS extract presented high contents of proanthocyanidins, resveratrol, and some phenolic acids. In contrast, SB contained a high concentration of ellagitannins, ellagic acid, and quercetin, exp…
Design, arte, divulgazione e crimine!

Salvo Naccari, parlando di “Connessioni”, su quale livello opera? Certamente non opera nella parte ideativa. Partecipa, semmai, alla selezione dell’opera, insieme all’artista. Esegue, ovviamente, la realizzazione materiale del pezzo. E si trova in una zona di contrattazione, con l’artista, circa l’esecuzione di questa realizzazione, cioè contratta in che modo rielaborare un’opera già conclusa. Coloro che intendono proseguire l’opera di un’artista – si sa – lo fanno a proprio rischio e pericolo. E Salvo Naccari sembra voler correre questo rischio e questo pericolo. L’intenzione è quella di estendere la portata dell’opera a un gran numero di persone o, meglio, di estendere la possibilità di f…
