This study was conducted to investigate the deposition of several mineral elements and the mRNA levels of mineral-related genes across different tissues of cherry valley ducks. The contents of magnesium (Mg), potassium (K), zinc (Zn), and selenium (Se) in ducks’ breast muscle, thigh muscle, liver, skin, and tibia at the age of 0, 21, 35, 49, and 63 days, respectively, were measured using an atomic fluorescence spectrophotometer, while the mRNA levels of mineral-related genes were detected by qRT-PCR. The results revealed that the dynamics of Mg and K were generally similar in each tissue, with a significant positive correlation (p < 0.05). In the breast muscle, thigh muscle, and liver, the contents of almost all mineral elements reached their peak values (p < 0.05) at the age of 49 to 63 days. Interestingly, the expression of most mineral-related genes was the highest at birth (p < 0.05). In addition, there was a significant negative correlation between the expression of ATP1A1 and the deposition of K (r = −0.957, p < 0.05), and a similar result was found for the expression of ATP8 and the deposition of Zn (r = −0.905, p < 0.05). Taken together, Mg and K could be used as joint indicators for the precise breeding of the high-quality strain of cherry valley ducks, while the age of 49 to 63 days could be used as the reference for the best marketing age. In addition, ATP1A1 and ATP8 could be used as the key genes to detect K and Zn, respectively. Hence, the findings of this study can be used to improve the production and breeding efficiency of high-quality meat ducks.

Background: Homocysteine (Hcy) has been suggested as an independent risk factor for atherosclerosis. Apolipoprotein M (apoM) is a constituent of the HDL particles. The goal of this study was to examine the serum levels of homocysteine and apoM and to determine whether homocysteine influences apoM synthesis. Methods: Serum levels of apoM and Hcy in 17 hyperhomocysteinemia (HHcy) patients and 19 controls were measured and their correlations were analyzed. Different concentrations of homocysteine (Hcy) and LY294002, a specific phosphoinositide 3- kinase (PI3K) inhibitor, were used to treat HepG2 cells. The mRNA levels were determined by RT-PCR and the apoM protein mass was measured by western blot. Results: We found that decreased serum apoM levels corresponded with serum HDL levels in HHcy patients, while the serum apoM levels showed a statistically significant negative correlation with the serum Hcy levels. Moreover, apoM mRNA and protein levels were significantly decreased after the administration of Hcy in HepG2 cells, and this effect could be abolished by addition of LY294002. Conclusions: resent study demonstrates that Hcy downregulates the expression of apoM by mechanisms involving the PI3K signal pathway.

A number of literature reports have shown that multi-view clustering can acquire a better performance on complete multi-view data. However, real-world data usually suffers from missing some samples in each view and has a small number of labeled samples. Additionally, almost all existing multi-view clustering models do not execute incomplete multi-view data well and fail to fully utilize the labeled samples to reduce computational complexity, which precludes them from practical application. In view of these problems, this paper proposes a novel framework called Semi-supervised Multi-View Clustering with Weighted Anchor Graph Embedding (SMVC_WAGE), which is conceptually simple and efficiently generates high-quality clustering results in practice. Specifically, we introduce a simple and effective anchor strategy. Based on selected anchor points, we can exploit the intrinsic and extrinsic view information to bridge all samples and capture more reliable nonlinear relations, which greatly enhances efficiency and improves stableness. Meanwhile, we construct the global fused graph compatibly across multiple views via a parameter-free graph fusion mechanism which directly coalesces the view-wise graphs. To this end, the proposed method can not only deal with complete multi-view clustering well but also be easily extended to incomplete multi-view cases. Experimental results clearly show that our algorithm surpasses some state-of-the-art competitors in clustering ability and time cost.

Periodic bathymetric surveys are carried out to define quantity of sedimented material in reservoirs, as well as to determine the areas most endangered by the silting process. Such surveys in the Republic of Macedonia were started as an obligatory and regular practice in the seventies of the last century, immediately after the formation of the larger artificial lakes. These were carried out for almost all reservoirs in the country and it can be said that there is already a sufficient amount of data on some of them that can serve as a basis for high quality analyses of the silting trend of the reservoirs and of the extent to which erosion is affecting the basin area. This paper provides a review of the results from the latest field surveys and analyses of changes in the configuration of the Shpilje reservoir bottom, carried out in the period 2014 to 2016.

The present investigation was carried out at the Research Fields, ICAR-Indian Institute of Oilseeds Research, Rajendranagar, Hyderabad, Telangana, India. The material for present study consisted of twenty newly developed mono and multi headed restorer lines including CMS lines. The data for agronomic and yield traits i.e. days to 50% flowering, days to physiological maturity, plant height, head diameter, volume weight, 100 seed weight, seed yield per plant oil content and oil yield was recorded. The analysis of variance revealed significant differences among the genotypes for almost all characters which favour the selection. Associations among characters especially indicated that among the seven traits studied, seed yield per plant had a highly significant positive association with head diameter and significant negative correlation with days to 50% flowering and days to maturity. The genotypes, COSF-6B, COSF-7B, RGP-11-P1-S2, RGP-58-P4-S1-1 and RGP-46-P3 were identified as the most important genotypes for different traits and should be utilized in heterosis breeding programme to realize high heterosis for yield and yield contributing traits.

Abstract Background: The chicken egg is one of the nature’s flawlessly preserved biological products, recognized as an excellent source of nutrients for humans. Selenium (Se) is an essential micro-element that plays a key role in biological processes. Organic Se sources have shown many advantages over inorganic Se in poultry and can be produced biologically by microbial reduction of Se. Therefore, the possibility of integrating Se enriched bacteria as a supplement in poultry feed can provide an interesting source of organic Se, thereby increase egg Se concentration, improve oxidative stability and offer health-related advantages to humans. The objective of this study was to examine the effects inorganic and different organic Se sources on egg yolk colour, antioxidant profile, oxidative stability, and storage effect in relation to the treatments for fresh and stored egg yolk at 4±2 0C for 14 days. Results: The results reveals that dietary Se supplementation, especially the organic (ADS18 > Se-Yeast) sources influence (p < 0.05) egg yolk colour. Dietary inorganic Se and organic Se were noted to significantly improves egg yolk and breast meat antioxidants profile (total carotenoid and phenol content). There was a significant (p < 0.05) decrease in total cholesterol in fresh, stored egg yolk and breast muscle of Se treated groups compared with control. Whereas for breast muscle, only hens with organic Se supplementation (ADS18 > Se-Yeast) showed lower (p < 0.05) cholesterol compared to inorganic and control hens. The oxidative stability parameters of the eggs, breast and thigh muscle, and plasma showed a significant decrease (p < 0.05) in primary oxidation products (MDA) concentrations with hens supplemented with ADS18. However, the MDA content increased (p < 0.05) with an advanced storage period in egg yolk. It should be noted that, compared to inorganic Se and basal diets, egg yolk from hens fed with organic Se remain fresh for 2 weeks.Conclusions: Dietary Se organic supplementation (ADS18 > Se-Yeast) improves egg yolk colour, antioxidant profile, and oxidative status of egg yolk and tissue. For egg enrichment and antioxidant properties, the source of supplemented organic Se is essential. Thus, ‘’functional eggs’’ enriched with organic selenium becomes possible to produced.

Soft rice is a kind of high-quality rice between glutinous rice and sticky rice. It has low amylose content, crystal clear grains, sweet taste, soft glutinous, and is suitable for cooking and porridge. Chalkiness in soft rice is a white opaque part formed by loose endosperm. It is an important character that affects the appearance quality, processing, and cooking quality of rice, and also an important limiting factor that restricts the standard rate of high-quality rice in China. The combination of scanning electron microscope and energy dispersive spectrometer (SEM-EDS) can be used for in-depth analysis of rice, visualization, and quantitative analysis of element distribution in rice. The results showed that there were many kinds of mineral elements in soft rice seeds, among which C and O were the most abundant, followed by N and P, and Mg, Al, P, S, K, Ca, Mn, and Zn were less. The contents of C, N, P, and S in the non-chalky area were significantly higher than those in the chalky area. Especially N and S were the best indicators of protein, and the contents in the chalky area were higher than those in the non-chalky area. It means that the protein content in the chalky part of soft rice seed is less than that in the non-chalky part, which affects the nutritional quality of soft rice. Therefore, the results of this study laid a solid foundation for the in-depth analysis of the distribution of mineral elements and protein in soft rice and their effects on the quality of soft rice, which also provided important information for the cultivation of new high-quality rice varieties in the future.

In the wake of the Crimean War, the upper military circles in Russia changed their thinking with regard to firearms. General Milyutin became Minister of War. It was the time when Alexander II reigned over Russia. In 1856, the calibre of Russian firearms was reduced to 6 inches, or 15.24 mm. The process of re-equipping the Russian army with M1856 rifles using expanding Minié bullets was launched. These rifles demonstrated that the percussion systems had reached the limit of their capacity for improvement. Nothing else could be improved in terms of their firing speed. Despite the resistance of the conservative military circles, Milyutin encouraged new inventions, and the 1860s became a period of experimentation with firearms. Some new cartridge systems were introduced. The high-quality M1856 percussion rifle was not destined to take part in war times, but the Russian army had been fully equipped with it for a short period of time. Almost all systems of the 1860s were based on this rifle. Over 10 systems of firearms with an internal needle fuse were proposed to the weapons commission. In 1866, the Englishman Karle proposed his own system with an internal needle fuse. Krnka, Berdan I, and Berdan II came next. After 1866, the Terry-Norman, Karle, and Krnka rifles entered the Russian army. These systems were developed on the basis of the 6-line M1856/58 rifle. The latter was converted into a rear-loading rifle. In 1869, the Krnka rifle was chosen as the main system, which became the main weapon of the Russian army in the following years. At the beginning of 1877, there were 613,297 Krnka rifles, 150,868 Karle rifles, 17,810 Berdan I and 325,254 Berdan II rifles in the Russian army.

This study aimed to investigate the effects of dietary supplementation with dl-methionine (dl-Met) and dl-methionyl-dl-methionine (dl-Met-Met) in breeding pigeons on the carcass characteristics, meat quality and antioxidant activity of squabs. A total of 324 pairs of breeding pigeons were selected and allotted to 9 treatments in a completely randomized design, and the birds were fed dietary treatments for 45 d, including a Met-deficient basal diet (BD, crude protein = 15%, Met = 0.25%) and BD + 0.15%, 0.30%, 0.45%, or 0.60% dl-Met or dl-Met-Met diets. Compared with the diet fed to the BD group, dietary dl-Met or dl-Met-Met supplementation effectively increased the carcass yield, semieviscerated yield, eviscerated yield, breast muscle yield, thigh muscle yield, a* value, catalase activity, total superoxide dismutase activity and glutathione peroxidase activity, but decreased the L* value, malonaldehyde concentration, drip loss and cooking loss of squabs (p < 0.05). The relative bioavailability values of dl-Met-Met relative to those of dl-Met were 467% and 376% based on carcass yield and breast muscle yield, respectively (p < 0.001). Moreover, dl-Met-Met was more effective than dl-Met in decreasing the drip loss and improving the antioxidant activity of the breast and thigh muscles of squabs (p < 0.05). As a source of Met, dl-Met-Met, rather than dl-Met, was more beneficial to squabs.
