Lumpy Skin Disease (LSD) and Foot-and-Mouth Disease (FMD) cause substantial economic losses on the livestock industry. Therefore, vaccinations have been implemented as the control strategy in endemic countries. However, the potential adverse effects of administering vaccines for both diseases simultaneously have not been thoroughly evaluated. The aim of this study was to assess the impact of vaccinating dairy cows with either or both LSD and FMD vaccines on milk production and physiological parameters such as milk temperature, rumination time and body weight. The experimental groups were divided into four according to the injection materials: 1) saline, 2) LSD vaccine, 3) FMD vaccine, and 4) both vaccines. The impact of vaccination on milk yield and physiological parameters was evaluated daily until 12 days post-vaccination, and milk components were analyzed twice, once per week. Among the experimental groups as well as each vaccine group, no statistically significant differences (p < 0.05) were observed at milk yield, milk components, or milk temperature. This suggests that simultaneous vaccination of LSD and FMD can be administered without adverse effects.

Cherry tomato (Solanum lycopersicum L,. var. cerasiforme Mill.) is small fruits with a bright red color resembling a cherry and having an excellent taste, sweet and juicy ambience. So far, no cherry tomato variety was registered in Ethiopia. Consequently, six genotypes were imported from National Institute of Horticulture and Herbal Sciences (NIHHS), Rural Development Administration (RDA) Republic of Korea, and field experiment was conducted in RCBD with three replications at six Ethiopian testing sites, with irrigation, during off-seasons of 2021 and 2022 to identify high yielding, well adapted and good quality varieties. The overall analysis of variance across locations and years showed non-significant difference among the genotypes for marketable and total yields. But separate analysis for each site has revealed significant differences among genotypes at Melkassa, Koka, Adami- Tulu and Fogera, unlike that of Kulumsa and Woramit. There were significant differences (P < 0.05) among these genotypes for fruit numbers per plant, average fruit weight, fruits per cluster, plant height, skin thickness, juice volume and total soluble solid. Wonhong No.3 gave higher marketable (24.49 t/ha) and total (26.19 t/ha) yields, and generally Wonhong Nos.3 and 5 had higher yields and good qualities across these tested locations and years. Hence, Wonhong No.3 (designated as Jorgie-1) was registered for its higher yield, non-cracking, good TSS and color, while Wonhong No.5 (renamed as Jorgie-2) was preferred for its smaller fruit size, reasonable yield and quality (TSS, color, non-cracking). Hence, both varieties were officially registered in 2023 season for commercial production in different agro-ecologies of Ethiopia, and they are believed to add more economic and nutritional values for the tomato producers and the consumers. They can also support the intensification of tomato cultivation in peri-urban and urban agriculture, where demands and thus government focus are increasingly growing.

Graphitic nitrogen-doped carbon film/nanoparticle composite, in which the films were wrapped and separated by the nanoparticles, was prepared through a simple co-calcination route. Due to its unique porous structure and improved nitrogen content, the as-prepared electrode material could exhibit high specific capacitances of 317.5 F g− 1 at 0.5 A g− 1 and 200.0 F g− 1 at 20 A g− 1, and stable cycling behavior with no capacitance decline after 10,000 cycles in three-electrode system. When assembled in two-electrode capacitor, its specific capacitance could be well kept at 265.5 F g− 1 at 0.5 A g− 1, and thus the supercapacitor with a high energy density of 9.22 Wh kg− 1 was obtained. The superior energy storage properties of the as-prepared material indicate its promising application as high-performance carbon-based electrode for supercapacitors.

A substantial quantity of discarded tires has inflicted harm on the environment. Microwave pyrolysis of discarded tires emerges as an efficient and environmentally friendly method for their recycling. This research innovatively utilizes the characteristics of microwave rapid and selective heating to pyrolyze waste tires into porous graphene under the catalysis of KOH etching. Moreover, this study comprehensively investigates the dielectric characteristics and heating behavior of waste tires and different proportions of waste tire–KOH mixtures. It validates the preparation of graphene through KOH-catalyzed microwave pyrolysis of waste tires, tracking morphological and structural changes under varying temperature conditions. The results indicate that optimal dielectric performance of the material is achieved at an apparent density of 0.68 g/cm3 at room temperature. As the temperature increases, the dielectric constant gradually rises, particularly reaching a notable increase around 700 °C, and then stabilizes around 750 °C. Additionally, the study investigates the penetration depth and reflection loss of mixtures with different proportions, revealing the waste tire–KOH mass ratio of 1:2 demonstrates favorable dielectric properties. This research highlights the impressive microwave responsiveness of the waste tire–KOH mixture, Upon the addition of KOH, the mixed material exhibits an augmented dielectric constant and relative dielectric constant, supporting the viability of KOH-catalyzed microwave pyrolysis for producing porous graphene from waste tires. This method is expected to provide a new method for the valuable reuse of waste tires and a technology for large-scale, efficient and environmentally friendly production of graphene.

Colorectal cancer (CRC) poses a significant global public health challenge, accounting for 10% of newly diagnosed cancer cases and causing 9.4% of cancer-related deaths. Conventional treatment methods like surgery, chemotherapy, and radiation have shown limited success despite the increasing incidence of CRC. Thus, there is an urgent need for innovative therapeutic approaches. Researchers are continually working on developing novel technologies, notably focused on the creation of safe and effective cancer nanomedicines, in their continuous effort to advance cancer treatment. Nanoparticles exist at the nanoscale. Nanoparticles at the nanoscale have distinctive properties that leverage the metabolic disparities between cancerous and normal cells. This property allows them to selectively induce substantial cytotoxicity in cancer cells while minimizing damage to healthy tissue. Carbon nanomaterials (CNMs), including graphene oxide (GO), carbon nanotubes (CNTs), and nanodiamonds (NDs), have undergone extensive investigation due to their biocompatibility, surface-to-volume ratio, thermal conductivity, rigid structural properties, and ability for post-chemical modifications. Notably, GO has emerged as a promising two-dimensional (2D) material for cancer treatment. Several groundbreaking nanoparticle-based therapies, predominantly utilizing GO, are currently undergoing clinical trials, with some already gaining regulatory clearance.

Background: Because oxidative stress can induce decreased quality of caprine semen during the storage, there has been limitation for the use of stored semen in the assisted reproductive technologies. The present study, therefore, assesses the potential of Annona muricata (A. muricata ) to reduce semen storage associateddamages. Methods: Semen was collected by electro-ejaculation from ten bucks, and extended with Tris-egg yolk (TEY) supplemented with A. muricata leaf aqueous extract (SAE) at 20 (SAE20), 40 (SAE40), and 80 (SAE80) μg/mL. Sperm variables including motility, motion characteristics, viability, membrane functionality, and DNA integrity were assessed at different storage periods (6, 24, 48, and 72 hr). In addition, oxidative stress indicators in the extender supplemted with SAE were also assessed for each group. Results: By adding SAE at 80 μg/mL in TEY, the storage of goat buck semen was improved, resulting in reduced loss of sperm motility, viability, DNA fragmentation, and membrane integrity during chilled storage at 4℃ for up to 72 hr. In addition, enrichment of TEY extender with SAE significantly (p < 0.05) reduced malondialdehyde, an indicator of oxidative stress, compared to the negative control. Conclusions: Supplementation of SAE in TEY extender can reduce buck spermatozoa liquid storage associated damages due to oxidative stress.

Chlorine is a crucial radionuclide that must be removed in irradiated nuclear graphite. Understanding the interaction between chlorine and graphene-based materials is essential for studying the removal process of 36Cl from irradiated nuclear graphite. In this study, first-principle density functional theory (DFT) was utilized to investigate the adsorption characteristic of chlorine on the original and reconstructed edges of graphene-based materials. Based on the calculation of adsorption energy of the structures after each step of adsorption, the most energetically favorable adsorption routes at four types of edge were determined: Along the armchair edge and reconstructed zigzag edge, the following adatoms would be adsorbed to compensate the distortion induced by the previously adsorbed atom. Meanwhile at the original zigzag edge, chlorine atoms would be adsorbed alternatively along the edge to minimize the repulsion between two adjacent chlorine atoms. The chemical nature of the bonds formed as a result of adsorption was elucidated through an examination of the density of states (DOS) for the two adsorbed chlorine atoms and the carbon atoms attached. Furthermore, to assess the relative stability of the adsorption structures, formation energy of all energetically favorable structures following adsorption was computed. Consequently, the predominant adsorption structure was identified as the reconstructed armchair edge with two chlorine atoms adsorbed. The desorption process of 36Cl2 from the predominant structure following adsorption was simulated, revealing an energy barrier of 1.14 V for desorption. Comparison with experimental results suggests that the chlorine removed from reconstructed armchair edges significantly contributes to the low-temperature removal stage of 36Cl from irradiated nuclear graphite.

The study investigated the influence of website features on the purchase intention of online fashion among Generation Z consumers in South Africa. This topic has received increasing attention against the backdrop of the rapidly growing ‘Digital Generation’, or ‘Millennial consumers’, who are one of the most tech-savvy generations. Despite the benefits that online shopping offers to both the business and the consumer, the act of buying clothes online has presented some challenges to customers. This study therefore aims to gather further insight in an attempt to provide fashion businesses with guidance to better succeed in encouraging customers to shop online. This study selected two visual elements (website aesthetics and product presentation) and two functional website features (website navigation, and security and privacy) and social norms, the test the effect they have on perceived ease of use, attitude and intention to purchase clothing online. The proposed conceptual model tested seven hypotheses of which four were supported. By means of an empirical study, 166 online surveys were collected from individuals within the Generation Z cohort and the analysis was done using SPSS27 by running multiple regression analysis to test the relationships between the variables. The results from this study provide global and local fashion brands with valuable insight into the consumption habits of young consumers in an emerging economy, and factors that drive online fashion consumption.

A phenylboric acid functionalized carbon dot (2-FPBA-CD) for rapid fluorescent sensing of glucose in blood was synthesized by simply mixing N, S-doped carbon dots (CDs) with phenylboric acid at room temperature. At pH 7.4, the response of 2-FPBA-CD to glucose could reach equilibrium in a very short time (10 min), with a wide responsive linear range of 19.70 μM to 2.54 mM, which can be applied to the detection of glucose in serum. The mechanism studies showed that the layered carbon film of 2-FPBA-CD aggregated after adding glucose, thereby leading to the fluorescence quenching of 2-FPBA-CD.

This study explores the histological features and Bmp4 expression patterns in the replaced tooth germ of Xenopus laevis . Tooth germ formation starts from the dental placode through epithelial-mesenchymal interactions, involving various signaling pathways such as Fgf, Shh, Bmp, and Wnt. In mice, Bmp4 expression in the dental placode inhibits Pax9 expression in the dental mesenchyme. Although absent in the presumptive dental lamina of birds and toothless mammals, Bmp4 remains conserved in reptiles and fish owing to gene duplication. However, its expression in amphibian tooth germs is poorly understood. Three-month-old X. laevis were employed in this study. Initially, samples underwent paraffin embedding and were sectioned into 5 or 12 μm ribbons for H&E staining and in situ hybridization, respectively. Results revealed teeth appearing in two maxillary rows: the labial side, with prefunctional and functional teeth, and the lingual side, with replaced tooth germs behind functional teeth. Enameloid was observed between the inner dental epithelium and dental mesenchyme at the cap or early bell stages, whereas enamel and dentin formed during the late bell or mineralization stages from the replaced tooth germ. Bmp4 expression was evident in the inner dental epithelium (ameloblasts), dental papilla (odontoblasts), stellate reticulum, and Hertwig’s epithelial root sheath. Overall, these findings highlight the conservation of Bmp4 expression in X. laevis tooth development.
