Rolul stresului oxidativ în patogeneza infertilității autoimune la bărbați și utilizarea nutrienților cu proprietăți antioxidante pentru îmbunătățirea calității spermei [Articol]
(Universitatea de Stat din Moldova, 2021) Șeptițchi, Vladimir; Leorda, Ana; Raischi, Viorica
Stresul oxidativ reprezintă un factor cauzal major în disfuncția spermei. Suplimentele care conțin substanțe nutritive pentru îmbunătățirea calității spermei au un efect semnificativ asupra funcției reproductive masculine. Odată cu utilizarea lor, se observă o scădere a deteriorării oxidative a ADN-ului, o îmbunătățire substanțială a parametrilor spermei și a funcției de reproducere în general. Utilizarea suplimentelor nutritive, concomitent cu modificări benefice ale dietei, ale stilului de viață și ale condițiilor de mediu, va permite îmbunătățirea nu doar a parametrilor care determină potențialul reproductiv, ci și a ratei natalității
Influența Covid-19 asupra metabolismului aminoacizilor în sistemul reproductiv la bărbați [Articol]
(Universitatea de Stat din Moldova, 2021) Garaeva, Svetlana; Leorda, Ana; Furdui, Vlada; Postolati, Galina
Țesuturile reproductive masculine, în special ale testiculului, sunt atacate de SARS-CoV-2, deoarece co-exprimă angiotensin convertaza și proteaza TMPRSS, necesare pentru intrarea virală. Sistemul reproductiv masculin al bărbaților tineri este mai vulnerabil în COVID-19, comparativ cu pacienții vârstnici. Pentru menținerea sănătății sistemului reproductiv este necesar de a monitoriza starea metabolismului proteic, a aminoacizilor cu proprietăți antioxidante, în special a glutationului, tioaminoacizilor, argininei, în serul sangvin și în sperma bărbaților infectați cu COVID-19 timp de cel puțin 3 luni de la ultimele simptome clinice.
Impacts of climate change on selected agrobiological and technological traits of the ‘Fetească Neagră’ cultivar: A comparative study of the Murfatlar vineyard (Romania) and the Codru wine region (Republic of Moldova) [Articol]
(Academy of Agricultural and Forestry Sciences – “Gheorghe Ionescu-Şişeşti” Horticulture Section, 2025) Ranca, Aurora; Alexandrov, Eugeniu; Tănase, Anamaria; Dina, Ionica; Artem, Victoria; Kwon, Min kyung; Cosma, Traian Stefan
Over the past decade, shifts in key climatic parameters in both wine-growing regions have brought notable changes to the agrobiological behavior of the indigenous ‘Fetească Neagră’ cultivar. These include a shorter vegetative period, an earlier onset of full ripening, and an advance in the grape harvest date. Traits such as fertility, productivity, and resilience to stress factors (drought, pathogen pressure) are directly shaped by these climatic shifts. This paper presents a comparative analysis of the evolution of principal climatic factors recorded between 2015 and 2024 and examines their impact on the phenology and grape quality of the 'Fetească Neagră' cultivar cultivated in both regions. The findings indicate an increase in average temperatures during the vegetative phase by 0.8–0.9 °C in both areas, coupled with uneven rainfall patterns marked by alternating dry periods and months with normal precipitation. In both vineyards, the vegetative cycle was reduced by 10–15 days, with full ripening now occurring in early September; the average vegetative period lasted around 120 days. Berry development accelerated by about 9 days at Murfatlar, where the ripening phase now begins at approximately 100 days of vegetation. At Codru, the ripening phase was shortened to 17 days instead of the previous 35. In terms of grape yield, no significant differences were observed between the two regions during the study period. However, improvements in quality were recorded: at Murfatlar, must sugar levels increased by 6.6 g/L, accompanied by a decrease in acidity; at Codru, must sugar levels rose by 8.39 g/L, with acidity stabilizing at 4.5 g/L tartaric acid. Correlation analyses highlight the considerable influence of temperature and precipitation on grape quality parameters for the 'Fetească Neagră' cultivar. The challenges posed by climate change for this variety in both regions are clear. To sustain wine quality, adaptive cultivation measures are needed, including improved soil water conservation, canopy management, grape shading, and other responsive viticultural practices.
Influence of the temperature stress on growth and development characters of the tomato genotypes [Articol]
(Museum of Oltenia Craiova, 2025) Mihnea, Nadejda; Lupașcu, Galina; Rusu, Vadim
The paper presents the results of screening of some varieties and 2 reciprocal F2 tomato hybrid combinations: Desteptarea x Flacara/Flacara x Desteptarea and Flacara x Vrojainii/Vrojainii x Flacara, based on resistance to low positive temperatures (10°, 11°C) in early ontogenesis. Seedlings grown at 25ºC served as a control. The analysis of the variability of the resistance character was performed based on germination, length of the embryonic radicle, stem and intact seedling. In the most cases, low temperatures produced significant inhibition of the both germination and growth organs. By cluster analysis (k-means method) in the 11°C variant, the varieties Chihlimbar, Desteptarea, Flacara, Mary Gratefully and the reciprocal combination F2 Desteptarea x Flacara/ F2 Flacara x Desteptarea were identified, which formed a separate cluster, with the highest values of the evaluated characters. In the case of temperature 10°C – the genotypes/populations Flacara, Mary Gratefully, F2 Desteptarea x Flacara, F2 Flacara x Desteptarea, F2 Flacara x Vrojainii presented the cluster with the highest germination values. Research of the influence of low positive temperatures on the distribution of tomato Solanum lycopersicum plants into phenotypic classes based on radicle length, demonstrated that the profile of the F2 reciprocal populations was influenced by both the temperature level and the parental entity when obtaining F1 reciprocal hybrids
History of use, importance and perspectives of Cuphea species [Articol]
(Slovak University of Agriculture in Nitra, 2025) Mihăilă, Victoria; Brindza, Jan
Cuphea P. Browne (Lythraceae J.St.-Hil.) comprises approximately 240–260 species that grow wild in the warm-temperate and tropical regions of South and Central America, as well as in the southern part of North America. The economic value of these plants is broad and multifaceted, with particular interest in their ability to synthesize and store oil (ranging from 16 to 42%) in seeds rich in capric, caprylic, lauric, and myristic acids. These oils are used in the production of laundry detergents, plasticizers, perfumes, pharmaceuticals, and other industrial products. Significant efforts have been made to adapt this genus to cultivation in temperate climates for the sustainable production of specialty oils. However, Cuphea species retain several wild-type traits such as indeterminate growth and flowering, seed shattering, deep seed dormancy, and the presence of viscous and glandular trichomes, which limit their agricultural potential. Various breeding strategies and modern biotechnological tools have been employed to mitigate these undesirable traits. One of the earliest milestones in the domestication of Cuphea species was the development of the PSR23 line, characterized by partial seed retention. The chemical composition, agronomic performance, disease resistance, and productivity of this line have since been extensively evaluated. This review provides an overview of the biology, distribution, and economic importance of Cuphea species. It also highlights the research history of the genus, including its taxonomic classification, morphological diversity, chromosome numbers, phytochemical profile, therapeutic potential, and progress in domestication.
