However, cardiotoxicity of PAT is rarely reported. Present study aimed at investigate the cardiotoxicity and relevant mechanisms of PAT on H9c2 cells. Cytotoxicity of PAT were evaluated by MTT assay and L ...
... Apple (Malus x domestica) fruit size is dependent on cell division and cell expansion, processes that are subsequently regulated by plant hormones such as auxins, gibberellins, and cytokinins. In this study, we investigated the role of cell division and cell expansion in apple growth and identified which of the two was more deterministic of final fruit size. Three cultivars of different sizes were ...

Abstract:
... Deep-rooted plants have increasingly been introduced after cropland abandonment with the implementation of the ‘Grain-for-Green’ program on the Chinese Loess Plateau (CLP). However, the temporal patterns of soil moisture content (SMC) and soil organic carbon (SOC) with stand ages and the potential role of deep roots driving these patterns within deep profiles are still poorly understood. Here, we ...

Abstract:
... The wood apple (Limonia acidissima) fruit is an underutilized fruit having extensive therapeutic and functional properties. The engineering properties (physical, frictional, thermal, textural, and mechanical) of the wood apple fruit aids in the assessment of the internal and external structure of the fruit. The mean principle dimensions of fruit are 7.79 cm, 7.60 cm, and 7.44 cm for longest dimens ...
... During 2017–2019, we observed Trichothecium spp. causing fruit rot in the field and in storage. This study was conducted to examine morphological differences of the species from different hosts, reveal the species’ potential host range, and evaluate the efficacy of five fungicides. Six strains of Trichothecium spp. isolated from nectarine, peach and walnut were selected. Although the colony morpho ...
... Apple orchards with minimal or reduced fungicide inputs in the Mid-Atlantic region of the United States have experienced outbreaks of severe premature defoliation with symptoms that matched those of apple blotch disease (ABD) caused by Diplocarpon coronariae. Fungal isolates obtained from symptomatic apple leaves and fruit produced uniform slow-growing, dark-gray colonies on peptone potato dextros ...

Abstract:
... Kalecik Karası (KK) is one of the important native grape varieties of Turkey used in red wine production. As an extension of a previous project that profiled the sensory characteristics of KK wines from different geographic regions of Turkey, this study aimed to investigate the chemical composition and sensory properties of KK wines belonging to different vintages from two different regions (Kalec ...
... This study tested the effect of convective and sun drying on quality parameters of apple, plum and a blend of apple and plum (50:50, w/w) leathers. Moreover, physical, sensory and chemical attributes determined by chemical methods were compared with an infrared spectroscopic method. All products had optimum values of L* (brightness), huge angle and chroma within naturally occurrence range. Convect ...
