Effect of omega‐3 polyunsaturated fatty acid supplementation on oxidative stress parameters and sex hormone levels of modern genotype sows

Veterinary Medicine and Science, Volume 9, Issue 1, Page 191-202, January 2023., 2023
In this study, we supplemented the diet of breeding sows either with omega‐6 (control) or omega‐3 (experimental) polyunsaturated fatty acids and examined their effects on the antioxidant system and hormone levels of the animals. In the blood levels of molecules indicating oxidative stress we experienced slight changes, but the feeding of omega‐3 fatty ...

Impact of dietary supplementation of unsaturated and saturated fatty acids on bone strength, fatty acids profile of thigh muscle and immune responses in broiler chickens under heat stress

Veterinary Medicine and Science, Volume 9, Issue 1, Page 252-262, January 2023., 2023
Results suggest that there is not beneficial effect of broiler performance due to adding different source of fat in broiler chicken diet under hot condition. Furthermore, the unsaturated fatty acids could improve profile of fatty acids in thigh and enhance immune responses in broiler chickens.

Confidence Intervals and Hypothesis Testing for High-Dimensional Regression [PDF]

arXiv, 2013
Fitting high-dimensional statistical models often requires the use of non-linear parameter estimation procedures. As a consequence, it is generally impossible to obtain an exact characterization of the probability distribution of the parameter estimates. This in turn implies that it is extremely challenging to quantify the \emph{uncertainty} associated

Two Modes of Riboflavin-Mediated Extracellular Electron Transfer in Geobacter uraniireducens

Frontiers in Microbiology, 2018
Anaerobes respire extracellular electron acceptors by extracellular electron transfer (EET). It is widely recognized that flavins can act as electron shuttles to facilitate this process. Flavin synthesis genes are widely distributed in Geobacter species.

Environmental and Nutritional Value of Fruit and Vegetable Peels as Animal Feed: A Comprehensive Review

Animal Research and One Health, EarlyView.
Fruit and vegetable peels, rich in nutrients such as fiber and phenolic compounds, can boost livestock productivity, enhancing milk, meat, and draught power. Their use as animal feed reduces organic waste, cuts greenhouse gas emissions, and decreases dependence on grain‐based feeds, offering a sustainable solution with significant nutritional and ...

The effect of acidifier supplementation on egg production performance and intestinal histology of Japanese quail (Coturnix japonica)

Veterinary Medicine and Science, Volume 9, Issue 1, Page 263-271, January 2023., 2023
This study aimed to investigate the effect of dietary supplementation of a commercial acidifier on egg production and histology of small intestine in laying Japanese quail. Our results indicate that supplementation of 1 and 2.6 g acidifier per kg of diet was associated with beneficial effects on egg production and quality, GIT pH and histology of small

Probing for sparse and fast variable selection with model-based boosting [PDF]

arXiv, 2017
We present a new variable selection method based on model-based gradient boosting and randomly permuted variables. Model-based boosting is a tool to fit a statistical model while performing variable selection at the same time. A drawback of the fitting lies in the need of multiple model fits on slightly altered data (e.g. cross-validation or bootstrap)

Understanding and Enhancing the Cycling Stability of Layered Double Hydroxides with Intercalated Ferrocene Anions for Energy Storage Application

Batteries &Supercaps, EarlyView.
In this work, mono‐ and divalent ferrocene carboxylates are successfully intercalated in the layered structure of Mg2Al(OH)6 to form the redox active materials MgAl‐FcMono and MgAl‐FcDi. Initial limitations concerning the cycling stability of electrodes based on these materials in aqueous electrolyte are overcome by the utilization of ionic liquid ...

Don't Fall for Tuning Parameters: Tuning-Free Variable Selection in High Dimensions With the TREX [PDF]

arXiv, 2014
Lasso is a seminal contribution to high-dimensional statistics, but it hinges on a tuning parameter that is difficult to calibrate in practice. A partial remedy for this problem is Square-Root Lasso, because it inherently calibrates to the noise variance.

Investigation of a broad‐spectrum micronutrient formulation as a possible precipitant of pharmacokinetic micronutrient–drug interactions

British Journal of Clinical Pharmacology, EarlyView.
Aims Daily broad‐spectrum micronutrients are being used by the general public and formulations are receiving research interest in mental health settings. Despite concerns about combining medicines and broad‐spectrum micronutrients in mental health care, there have not been any formal evaluations of potential interactions.
