Artificial cells are synthetic constructs that mimic the architecture and functions of biological cells. Artificial cells are designed to replicate the fundamental principles of biological systems while also have the ability to exhibit novel features and functionalities that have not been achieved before. Mainly, Artificial cells are made up of a basic structure like a cell membrane, nucleus, cytoplasm and cellular organelles. Nanotechnology has been used to make substances that possess accurate performance in these structures. There are many roles that artificial cells can play such as drug delivery, bio-sensors, medical applications and energy storage. An additional prominent facet of this technology is interaction with biological systems. The possibility of synthetic cells being compatible with living organisms opens up the potential for interfering with specific biological activities. This element is one of the key areas of research in medicine, aimed at developing novel therapies and comprehending life processes. Nevertheless, artificial cell technology is not exempt from ethical and safety concerns. The interplay between these structures and biological systems may give rise to questions regarding their controllability and safety. Hence, the pursuit of artificial cell research seeks to reconcile ethical and safety concerns with the potential advantages of this technology.

Herbicides (HBs) are an integral part of modern agricultural practice globally as one of the most suitable methods for chemical weed control. Hence, they may inadvertently damage crops through similar mechanisms well-functioning at weeds. Tolerance to three categories of treatments (tribenuron-methyl, 2,4 D and their combination), and the impact of the mode of application (pre-treatment of seeds or spraying on plants) was assessed through morphometric analysis (total plant length, root length, stem length, lengths of the first three leaves, relative water content-RWC), and pigment content analysis for some wheat (Triticum aestivum L.) cultivars in use in Albania. Results speak of a cultivar specific tolerance to each HB category, discriminating “Dajti” as the most resistant cultivar, and suggesting that the stress imposed to plants by the combination of HBs can produce significant differences in pigment content. The mode of treatment, on the other side showed that glyphosate pre-treatment of seeds led to inhibition of germination, and plants germinated from seed pre-treatment with in 2,4-D displayed significant modification of plant morphology, and germination rate, and had limited impact on RWC. On contrary, few statistically significant changes in morphometric traits and pigments content were evidenced when plants were treated with 2,4-D or glyphosate after the germination. In conclusion, the combination of HBs produced significant changes in plant pigments content compared to the impact of each HB alone, and the pre-treatment of seeds lead either to inhibition or delayed germination. Based on the above we recommend avoiding these practices, and suggest further exploration of alternative HB combinations and modes of treatment before large scale applications.

Heavy metal contamination is an increasingly pressing global ecological concern adversely affecting plant growth. Phytoremediation is an eco-friendly and low-cost approach to help solve this problem by using plants to remove metals. This study aimed to evaluate the phytoremediation potential of four Plantago species, exposing them to different concentrations (0, 150, 300, 600 and 900 ppm) of zinc, copper, and iron during germination and early seedling growth. These are generally the phases of the plant life cycle most sensitive to stress. The germination percentage (GP), mean germination time (MGT), radicle, hypocotyl and cotyledons length, biomass, water content and tolerance index (TI) were recorded under controlled conditions. The results indicated that metal-induced stress significantly reduced GP, increased MGT, and inhibited seedling growth with increased metal concentration. The relative toxicity of the tested metals could be ranked as Fe > Cu > Zn. Regarding the Plantago species, P. tunetana and P. lanceolata could be considered highly tolerant, P. albicans moderately tolerant, and P. afra low-tolerant to metal toxicity during germination. Therefore, P. tunetana and P. lanceolata present an excellent potential for phytoremediation of metal-contaminated zones.
重金属污染是一个日益紧迫的全球生态问题，对植物生长造成不利影响。植物修复是一种生态友好且成本低廉的方法，通过利用植物去除金属来帮助解决这一问题。本研究旨在评估四种车前草的植物修复潜力，在它们发芽和幼苗生长期间，将它们暴露在不同浓度（0、150、300、600 和 900 ppm）的锌、铜和铁中。这些阶段通常是植物生命周期中对胁迫最敏感的阶段。在对照条件下记录了发芽率（GP）、平均发芽时间（MGT）、胚根、下胚轴和子叶长度、生物量、含水量和耐受指数（TI）。结果表明，随着金属浓度的增加，金属诱导胁迫会显著降低 GP 值，增加 MGT 值，并抑制幼苗的生长。受测金属的相对毒性依次为铁 > 铜 > 锌。在车前草物种中，P. tunetana 和 P. lanceolata 对萌芽期金属毒性的耐受性较高，P. albicans 的耐受性一般，P. afra 的耐受性较低。因此，P. tunetana 和 P. lanceolata 具有对金属污染区进行植物修复的巨大潜力。

The current study aims to provide insights into the drying of agro products, with a specific focus on Capsicum annum L. (red pepper). Among open sun drying (OSD), polyethylene bag drying (PBD), and polycarbonate sheet drying (PCSD), PCSD was efficient requiring around 24 hours with a maximum yield of 350 g of dried product per 1000 g of supplied fresh peppers. The PCSD dried chili also showed greater retention of antioxidant markers (capsaicin and dihydrocapsaicin) than OSD and PBD as evidenced by UV-VIS spectroscopy. Additionally, the PCSD dried chili demonstrated highest antioxidant potential via ABTS (2, 2′-Azinobis-3-Ethylbenzothiazoline-6-Sulfonic Acid). Interestingly, the presence of various aromatic compounds and other chemical groups, indicated the occurrence of capsaicin and dihydrocapsaicin in each drying method used. The study suggests that PCSD sheet drying is an efficient and cost-effective approach that can conserve the antioxidant potential of agro products such as red pepper.

In the recent study, the entomopathogenic fungus, Beauveria bassiana and Metarhizium anisopliae against wheat aphid species in field conditions to check the insecticidal effect of entomophathogenic fungi were used to evaluate their pathogenecity against adults of different aphid species i.e., Schizaphis graminum, Rhopalosiphum padi, Brevicoryne brassicae and Lipaphis erysimi, and their natural enemies of crops. Beauveria bassiana and Metarhizium anisopliae were found effective at all concentrations i.e., 1×106, 1×107 and 1×108 cfu/ml on all aphid species, but the uppermost concentration (1×108 cfu/ml) provided maximum control within a short period of time. B. bassiana concentration (1×108 cfu/ml) proved to be lethal to wheat aphid species after the 3rd day. Mortality of wheat aphids were observed at maximum highest concentration of 1×108 cfu/ml were in range of 100% at 8th day of treatment for different aphid species treated at various concentrations. M. anisopliae (1×108 cfu/ml) showed excellent mortality 85% and 84% at 5th and 6th day respectively, against wheat aphid species. In conclusion, the use of Beauveria bassiana and Metarhizium anisopliae as biopesticides in agriculture is a sustainable and environmentally friendly approach to control insects’ pests.

The purpose of this study was to evaluate the effect of different levels of probiotic on colony functional traits, honey quantitative and qualitative parameters and gut microbial flora in honey bees. A total of 56 hives were randomly allocated to 8 treatments with 7 replicates in the city of Firouzkoh (Iran) for about 60 days. Experimental treatments that were included: control, 2 g antibiotic, 1 g probiotic, 2 g probiotic, 3 g probiotic, 1 g antibiotic + 1 g probiotic, all per liter of syrup for each hive. The results showed that hives fed with treatments 2 g or 3 g probiotic per liter of syrup had higher hive population and honey production than the other treatments (p<0.05). Adding 2 g or 3 g probiotic per liter of syrup increased lactobacillus counts in bees’ intestines compared to the other treatments (p<0.05). Also, supplementation of 1 g or 2 g probiotic and 2 g antibiotic per liter of syrup for each hive decreased Escherichia coli counts in the intestine compared to the other treatments (p<0.05). The adding 1 g or 2 g probiotic per liter of syrup for each hive increased the levels of fructose and glucose in honey compared to the other treatments (p<0.05). The supplementation of 1 g or 2 g probiotic per liter of syrup decreased sucrose in honey compared to the other treatments (p<0.05). The results of the present study suggest that probiotic might be used as a feed additive for increased honey quality and gut microbial flora improvement in honey bees.
