Antibiofilm and Antimicrobial Potentials of Novel Synthesized Sulfur Camphor Derivatives.

The question being posed by scientists around the world is how different chemical modifications of naturally occurring compounds will affect their antimicrobial properties. In the current study, sulfur derivatives of camphor containing a sulfur atom were tested to detect their antimicrobial and antibiofilm potentials. The new compounds were tested on eight Gram-positive strains ( (3 isolates), (4 isolates), and (1 isolate)) and eight Gram-negative strains ( (6 isolates), (1 isolate), and (1 isolate)).

Comparison of Antibiotic Use and the Frequency of Diseases Depending on the Size of Herd and the Type of Cattle Breeding.

Diseases are responsible for losses in livestock production by increasing animal mortality and reducing productivity. The administration of antibiotics can help mitigate these negative effects. However, inappropriate use can lead to severe complications, such as raising antibiotic resistance.

Comparison of the Effects of Essential Oils from and on Selected Bacteria, Rumen Fermentation, and Methane Production-In Vitro Study.

Milk Odd- and Branched-Chain Fatty Acids as Biomarkers of Rumen Fermentation.

Cow's milk and dairy products are the primary sources of OBCFAs, which have beneficial health properties. The goal of this study was to identify the factors that influence the content of OBCFAs in cow's milk and to indicate which OBCFAs can serve as biomarkers for fermentation processes. The content of OBCFAs in milk depends on the species of ruminants, with studies showing that this varies between 3.

Specifically, the aim was to understand how it influences productive performance and indicators of iron metabolism, hematology and biochemical and parameters during feeding with whole milk before weaning. The study was carried out on 20 Polish Holstein Friesian calves.

Biochemical and Molecular Investigation of the Effect of Saponins and Terpenoids Derived from Leaves of on Lipid Metabolism of Obese Zucker Rats.

Ilex paraguariensis, the holly tree, is a plant with recognized biological properties, whose aqueous infusions are known as “Yerba mate”, that regulate lipid metabolism, reduce obesity, and improve brain stimulation. In the present study, the effect of standardized saponin and terpenoid fractions of a European taxon, Ilex aquifolium, on blood biochemical parameters in a rat model of metabolic disorder, (fa/fa) Zucker, are presented. The profiles of the volatile fractions of two species and six European varieties of Ilex were investigated.

Clinical Application of Bioextracts in Supporting the Reproductive System of Animals and Humans: Potential and Limitations.

There is an increasing demand of spices and herbs in developing countries due to the beneficial effects of plants and herbal preparations as medicines. The basic technological process of obtaining extracts from natural raw materials is extraction, consisting in etching with solvents. Plant extracts are extremely complex, multicomponent mixtures obtained from flowers, fruits, leaves, stems, twigs, or seeds of various plant materials.

Exosomes - Spectacular role in reproduction.

Exosomes are nano-sized structures that are found in semen, epididymal -fluid, endometrium, as well as in follicular fluid. They are responsible for transporting bioactive cargo- proteins, lipids, and nucleic acids. Exosomes have been proven to influence processes in both female and male reproductive systems, including gametogenesis, acrosomal reaction, sperm capacitation, and embryo implantation in the endometrium.

Biological Potential and Chemical Profile of European Varieties of .

Plants of the genus are widespread throughout the world, with its best-known representative being from South America. The European species shows similarities in its terpenoid, sugar and phenolic acid profiles. Using aqueous extracts of as a supplement in Wistar rats showed that, despite the lack of caffeine, it had strong hypocholesterolemic effects.

Composition and Antimicrobial Activity of Leaves Water Extracts.

Plants from the genus are known for properties such as antimicrobial and anti-inflammatory activity, can act as antiobesity agents and thus can be helpful in medicine. Some holly species, such as (widely known in the form of popular beverage: yerba mate), have been investigated, while others have been partially researched or remain unknown. Therefore, we performed qualitative and quantitative phytochemical analyses and screened antimicrobial properties of lesser-studied species ( L.

Volatile Composition and Sensory Properties as Quality Attributes of Fresh and Dried Hemp Flowers ( L.).

Flowers of hemp ( L.) are widely used in cosmetics, food, and in the pharmaceutical industry. The drying process plays a key role in retention of aroma and also in the quality of products.

Metabolism, Ketosis Treatment and Milk Production after Using Glycerol in Dairy Cows: A Review.

The aim of this paper is to review and systematize the current state of knowledge on glycol metabolism in cattle. Glycerol, derived from biodiesel production, must be purified in order to be a useful product for feeding livestock. The use of glycerol in the feeding of ruminants can be justified for several reasons: (i) it is a source of energy in the ration, (ii) it is a glucogenic precursor, and (iii) it may have an effect on milk composition.

Effects of n-3 fatty acids on growth, antioxidant status, and immunity of preweaned dairy calves.

This study aimed to estimate the influences of flax oil and a mixture of ethyl esters of fatty acids from flax oil added to a milk replacer (MR) formulation on the biochemical, immunological, and antioxidant status of blood, production parameters, and health of calves. Twenty-seven Holstein-Frisian calves were assigned to 3 groups: the control group without fat added to the diet (CON, n = 9), a group receiving ethyl esters of flax oil (10 g/d) with lyophilized apples (25 g; MRE), or a group receiving flax oil (10 g/d) with lyophilized apples (25 g; MRL). The study was conducted from d 14 to d 42 of life.

Application of , and Mixture Extracts in a Rabbit Model with Experimentally Induced Infection.

The study evaluated the anti-colibacteriosis efficacy of herbs in experimental infection by rabbit pathogenic strain of O103 . It also studied the effects of herbal mixture added to feed or water on blood parameters. This animal model was used since some strains pathogenic for rabbits are similar to the strains that are pathogenic to humans.

Effects of Protein-Iron Complex Concentrate Supplementation on Iron Metabolism, Oxidative and Immune Status in Preweaning Calves.

The objective of this study was to determine the effects of feeding protein-iron complex (PIC) on productive performance and indicators of iron metabolism, hematology parameters, antioxidant and immune status during first 35 days of a calf's life. Preparation of the complex involved enzymatic hydrolysis of milk casein (serine protease from yeast). Iron chloride was then added to the hydrolyzate and lyophilizate.

The 4-wk experiment was conducted on 30 Polish Holstein Friesian cows.

Application of Cornelian Cherry Iridoid-Polyphenolic Fraction and Loganic Acid to Reduce Intraocular Pressure.

One of the most common diseases of old age in modern societies is glaucoma. It is strongly connected with increased intraocular pressure (IOP) and could permanently damage vision in the affected eye. As there are only a limited number of chemical compounds that can decrease IOP as well as blood flow in eye vessels, the up-to-date investigation of new molecules is important.
