Secondary structure prediction revealed the dominance of the coils enhances AKD9 activity and stability under saline and alkaline conditions. Based on molecular docking, AKD9 showed very promising binding affinities towards casein substrate with expected intrinsic proteolytic activities matching our obtained in vitro results. In conclusion, AKD9 alkaline serine protease seems to be a significant candidate for industrial applications because of its stability, hydrophilicity, enhanced thermostability, and alkali-halo stability.Ethiopia, the second-most populous country in Africa with 110 million inhabitants, has one of the oldest public telecommunication operators established in 1894. Despite its age, Ethiopian telecommunication remains one of the least developed in the world. According to ITU, in 2019, mobile-cellular subscription (per 100 people) was 39 % and 20 % Internet penetration. As of June 2018, the international transmission speed per Internet user was two kbits/s. Different studies widely acknowledge that no modern economy can be developed short of telecommunication services. It is no wonder that Ethiopia is depicted as one of the weakest economies in the world. This paper identifies the causes for extraordinarily poor telecommunications service in Ethiopia and offers recommendations for near-term improvement. The approach considered includes existing work surveys and document examination, and to this end, the work has relied primarily on secondary data sources. Inexperienced and ineffectual regulatory oversight, absence of facilities-based competition, inadequate interconnection with the neighboring nation's networks, and inability to localize outbound traffics are identified as factors affecting the Ethiopian telecom industry performance. Full liberalization with an effective regulatory body and hosting a sizeable Internet Exchange Points (IXPs) are recommended for better connectivity and a thriving digital ecosystem in Ethiopia.[This corrects the article DOI 10.1016/j.heliyon.2021.e07939.].Microorganisms in clay barriers could affect the long-term performance of waste containers in future deep geological repositories (DGR) for used nuclear fuel through production of corrosive metabolites (e.g., sulfide), which is why clay materials are highly compacted to reduce both physical space and access to water for microorganisms to grow. However, the highly compacted nature of clays and the resulting low activity or dormancy of microorganisms complicate the extraction of biomarkers (i.e., PLFA, DNA etc.) from such barriers for predictive analysis of microbial risks. In order to overcome these challenges, we have combined culture- and 16S rRNA gene amplicon sequencing-based approaches to describe the functional diversity of microorganisms in several commercial clay products, including two different samples of Wyoming type MX-80 bentonite (Batch 1 and Batch 2), the reference clay for a future Canadian DGR, and Avonlea type Canaprill, a clay sample for comparison. Microorganisms from as-received bentonitesrill microcosms. Exploration of potential metabolic pathways in the bacterial communities from the clay microcosms suggested variable patterns of sulfur cycling in the different clays with the possible prevalence of bacterial sulfate-reduction in MX-80 bentonite, and probably successive sulfate-reduction/sulfur-oxidation reactions in Canaprill microcosms. Furthermore, analysis of potential metabolic pathways in the bentonite enrichments suggested that bacteria with acid-producing capabilities (i.e., fermenters and acetogens) together with sulfide-producing prokaryotes might perhaps contribute to corrosion risks in clay systems. However, the low activity or dormancy of microorganisms in highly compacted bentonites as a result of severe environmental constraints (e.g., low water activity and high swelling pressure in the confined bentonite) in situ would be expected to largely inhibit bacterial activity in highly compacted clay-based barriers in a future DGR.An abattoir-based survey was conducted in Addis Ababa from December 2018 to April 2019 with the objectives of determining the prevalence of bovine cysticercosis and the viability of Taenia saginata cysticerci. Routine meat inspection was performed on the study animals. Palpation followed by incision of the heart, tongue, triceps muscle, masseter muscle and diaphragm were made to detect the presence of T. saginata cysts. From the detected cysts, 41 were randomly selected and subjected to viability test. From the total 500 study animals, 14(2.8%) had varying number of T. saginata cysts. The highest proportion of T. saginata cyst was observed in the triceps muscle 6(42.8%), followed by heart 3(21.4%), tongue 2(14.3%) and masseter muscle 2(14.3%). There was no cyst observed in the liver or diaphragm. Of the total randomly selected 41 cysticerci, 20(48.8%) were found to be viable while the rest 21(51.2%) cysticerci were found to be non-viable. Sex, breed, age, and body condition of the study animals were found to have no significant association with the occurrence of cysticerci (P > 0.05). Even though routine meat inspection has low sensitivity and usually under-estimates the prevalence of the disease, bovine cysticercosis was found to be prevalent in the study area. Therefore, an appropriate control program involving enforcement of meat inspection, promoting public awareness and improving personal and environmental hygiene should be designed and implemented.The most recent Black Lives Matter moment provides an important opportunity for consideration of the interlocking social and political systems that contribute to ongoing racism and racial inequality. What does this mean in the context of reproductive biomedicine? Which lives do reproductive biomedicine devalue and how? In this commentary, I address why reproductive biomedicine is an important site for reflection on race, and how the Reproductive Justice Movement calls on us to shift our thinking. I argue for the need to recognize the deep connections between reproductive biomedicine and eugenics, and then offer some examples of racialization in reproductive biomedicine through assisted reproductive technology. Finally, I consider what steps practitioners might take to be part of the change for which this Black Lives Matter moment calls.New Zealand and Australia are countries which currently prohibit donor payment and require open-identity forms of donation. This study explored the concerns of fertility stakeholders regarding payment which would constitute financial reward for gamete donation, and factors predicting such concerns. A total of 434 participants from across New Zealand and Australia completed an online survey anonymously. Participants included those with infertility and treatment experience, donors, recipients, donor-conceived people and clinic professionals. Results indicated that participants' concerns related to their assumptions about the type of donor motivated by financial reward, and the possibility that, if paid, donors might conceal information relevant to treatment and the donor-conceived person. Furthermore, participants were concerned about increasing recipient costs. Participants with personal experience of infertility held stronger concerns overall. Professionals expressed concerns of clinical relevance, such as the withholding of donor information relevant to treatment outcomes. The lowest levels of concern were expressed in relation to payment devaluing the meaning of human life. Qualitatively, themes highlighted concerns regarding payment enticing the 'wrong' type of donor, increased cost to recipients, and concern about the wellbeing of donor-offspring. Collectively, such concerns must be understood against the New Zealand and Australia open-identity donation context which enables the possibility of contact between donors and offspring. These findings indicate that donor recruitment campaigns need to account for different stakeholder concerns, and consider ways to address donor shortages effectively while remaining compliant with legislative requirements.In ovo feeding of vitamin C (VC) has positive effects on the growth performance, immune and antioxidant function in poultry, which indicates that increasing VC content in eggs may be of benefit. This study was to investigate the effects of dietary VC supplementation on VC synthesis and transportation and egg deposition. In Exp. 1, in order to select a suitable animal model, VC content was detected in different eggs from different layer species. Vitamin C content was lower in ISA Brown breeder eggs and Hy-Line Brown layer eggs (P less then 0.05) then in Arbor Acres breeder eggs. In Exp. 2, a total of 24 Hy-Line Brown layers (42-week-old) were randomly divided into 3 treatments with 8 replicates and fed a basal diet with VC at 0, 200 and 400 mg/kg. Sodium-dependent VC transporter 1 and 2 (SVCT1 and SVCT2) expressions were higher in ileum than in duodenum and jejunum (P less then 0.05). SVCT1 expression was higher but SVCT2 expression was lower in the magnum than in the ovary (P less then 0.05). L-Gulonolactone oxidase (GLO) and SVCT1 expressions were higher but SVCT2 was lower in the kidney than in the liver (P less then 0.05). Dietary VC supplementation at 400 mg/kg increased SVCT1 expression in duodenum, ovary and magnum, but decreased GLO and SVCT1 expression in liver (P less then 0.05). Dietary VC supplementation at 200 and 400 mg/kg increased SVCT2 expression in duodenum, but decreased GLO and SVCT1 expression in kidney and SVCT2 expression in liver (P less then 0.05). Dietary VC supplementation promoted VC absorption in duodenum and jejunum, but reduced endogenous VC synthesis in liver and kidney. Although dietary VC supplementation enhanced VC transportation in ovary and magnum, it did not increase VC deposition in produced eggs.Gossypol, a phenolic compound found in the cotton plant, is widely distributed in cottonseed by-products. Although ruminant animals are believed to be more tolerant of gossypol toxicity than monogastric animals due to rumen microbial fermentation, the actual mechanisms of detoxification remain unclear. In contrast, the metabolic detoxification of gossypol by Helicoverpa armigera (Lepidoptera Noctuidae) larvae has achieved great advances. The present review discusses the clinical signs of gossypol in ruminant animals, as well as summarizing advances in the study of gossypol detoxification in the rumen. It also examines the regulatory roles of several key enzymes in gossypol detoxification and transformation known in H. armigera. With the rapid development of modern molecular biotechnology and -omics technology strategies, evidence increasingly indicates that research into the biological degradation of gossypol in H. selleck products armigera larvae and some microbes, in terms of these key enzymes, could provide scientific insights that would underpin future work on microbial gossypol detoxification in the rumen, with the ultimate aim of further alleviating gossypol toxicity in ruminant animals.Maternal sodium butyrate (SB) intake has important effects on offspring growth and development. This study aimed to investigate the impacts of maternal SB supplementation during gestation and lactation on fatty acid composition and lipid metabolism in the offspring skeletal muscle of pigs. Twenty sows (Yorkshire, parity 2 to 3) were assigned to the control group (diets without SB, n = 10) and SB group (diets with 0.1% SB, n = 10). The results showed maternal SB supplementation throughout gestation and lactation increased (P less then 0.05) body weight of offspring piglets at weaning. The concentrations of triglyceride in plasma and milk were enhanced (P less then 0.05). Maternal SB induced (P less then 0.05) lipid accumulation with increased expression of peroxisome proliferator activated receptor γ (PPARγ) by enrichment of the acetylation of H3 acetylation K27 (H3K27) in offspring skeletal muscle. Meanwhile, the concentrations of C182n-6, C183n-3, total polyunsaturated fatty acid (PUFA), n-6 PUFA and n-3 PUFA decreased (P less then 0.
