Nutrition status of greenhouse tomato grown in intert media. Part I. Macroelements

Piotr Chohura, Andrzej Komosa · 2003 · Acta Scientiarum Polonorum: Hortorum Cultus

In the experiments carried out in the years 1998-1999 the effect of inert media and fertilization levels on the nutrition status of greenhouse tomato cv. ‘Maeva F1’ was investigated. Two feeding solutions were used: I, containing (in mg dm-3): N-NO3 – 189, P – 62, K – 371, Ca – 190, Mg – 49, Fe – 0.84, Mn – 1.87, B – 0.32, Zn – 2.01, Cu – 0.048, Mo – 0.048, pH 5.5, EC – 3.2 mS cm-1; and solution II with the concentration increased by 20%, and three inert media: rockwool (Grodan), polyurethane foam (Inert) and expanded clay (granulation 4–8 mm). In the index parts of the tomato (9–10 leaf from

Characterisation of osteogenic and vascular responses of hMSCs to Ti-Co doped phosphate glass microspheres using a microfluidic perfusion platform

Carlotta Peticone, David De Silva Thompson, Nikolay Dimov et al. · 2020 · Journal of Tissue Engineering

Using microspherical scaffolds as building blocks to repair bone defects of specific size and shape has been proposed as a tissue engineering strategy. Here, phosphate glass (PG) microcarriers doped with 5 mol % TiO 2 and either 0 mol % CoO (CoO 0%) or 2 mol % CoO (CoO 2%) were investigated for their ability to support osteogenic and vascular responses of human mesenchymal stem cells (hMSCs). Together with standard culture techniques, cell-material interactions were studied using a novel perfusion microfluidic bioreactor that enabled cell culture on microspheres, along with automated processin

IMPACT OF CULTIVAR ON THE NUTRITIONAL STATUS OF THE YOUNG APRICOT TREES (Prunus armeniaca L.)

Ljiljana Bošković-Rakočević, Tomo Milošević, Jelena Milivojević et al. · 2012 · Acta Scientiarum Polonorum: Hortorum Cultus

Mineral nutrition of apricot is very specific and depends on different factors such as soil fertility, soil pH, weather conditions, cultivars, rootstocks, fertilizers, age of trees etc. For these reasons, during 2008 and 2009 we evaluate nutrient status of five apricot cultivars (Vera, Aleksandar, Biljana, Harcot, Roxana) at 120 days after full bloom (DAFB) grown on acidic soil in the region of Čačak (Western Serbia). The results showed no statistically significant variations in the N, K and Ca content of apricot leaves among cultivars, as opposed to significant differences in the content of P

Effect of carbamazepine and levetiracetam on coagulation parameters: Prothrombin time, activated partial thromboplastin time, D-dimer, and fibrinogen levels

Li Jiaohui, Zhong Chengyun, Bian Guanji · 2025 · Journal of Medical Biochemistry

Background: Epilepsy is a prevalent neurological disorder, and evaluating its treatment strategies is highly significant. This study aimed to compare the effects of monotherapy with carbamazepine and levetiracetam on the results of coagulation tests, including prothrombin time, activated partial thromboplastin time, fibrinogen, and D-dimer levels, as well as on seizure control in patients with partial-onset epilepsy. Methods: A total of 89 patients diagnosed with POE and treated at our hospital between January 2023 and January 2024 were enrolled. The patients were divided into the carbamazepin

Alteration in prooxidant-antioxidant balance associated with selenium concentration in patients with congenital hypothyroidism

Rostami Shilan, Fathollahpour Asadollah, Abdi Mohammad et al. · 2018 · Journal of Medical Biochemistry

Background: There is a paucity of studies regarding oxidative balance and selenium (Se) status in congenital hypothyroidism. Recently, more attention has been given to the use of Se supplementation as a new treatment for thyroid disorders. Oxidative stress increases in different thyroid disorders and causes many pathological outcomes. The present study aimed to determine the serum prooxidant-antioxidant balance (PAB), Se, thyroid stimulating hormone (TSH) and free thyroxine (FT4) concentration in congenital hypothyroidism (CH) patients and the association of their probable change with hematolo

Long-term impact of deficit irrigation on the physiology and growth of grapevine cv. ‘Prima’ grafted on various rootstocks

Alper Kucukbasmaci, Ali Sabir · 2019 · Acta Scientiarum Polonorum: Hortorum Cultus

Testing the globally popular grapevine rootstocks for affinity with new grape cultivars or tolerance potential to stress factors like drought is essential for districts where supplemental irrigation is more frequently needed due to the pressures of a global climate change. In this study, a seasonal evaluation of leaf gas exchange, leaf temperature, leaf greenness (chlorophyll content prediction) and vegetative development of Vitis vinifera L. cv. ‘Prima’ grafted to different rootstock genotypes having great variability in drought tolerance, were investigated. The experiment was conducted in a
