In an investigation of the reputed expectorant action of iodides, some 300 to 400 rabbits and cats were urethanized and arranged for the collection of respiratory tract fluid (R.T.F.). Potassium iodide and the synthetic, organic iodides Siomine (N.N.R.), and Iod-Ethamine, given by stomach tube, significantly augmented the output of R.T.F. in doses comparable to the recommended human dose. Iodized proteins, such as Iodalbin (N.N.R.) and Iodo-Casein (N.N.R.), and iodized fatty acids or oils, such as Lipoiodine (N.N.R.), Iodo-starine (N.N.R.), Lipiodol (N.N.R.), Oridine (N.N.R.) Stearodine (N.N.R.), Sajodin (N.N.R.), and Iodicin, had no effect upon the volume output of R.T.F., even when given in a wide range of doses. The mechanism of expectorant action was studied with potassium iodide, which, when given to urethanized cats in which the anterior and posterior gastric branches of the vagus nerve had been severed, caused no increase in the output of R.T.F., proving that the expectorant action was by way of a reflex from the stomach, probably up the afferent vagus to the medulla oblongata and then down the efferent vagus to the bronchial glands. No evidence was found that the expectorant action of iodides was due to a direct effect upon the bronchial glands, but after giving potassium iodide and Iod-Ethamine to cats and rabbits, there followed a marked increase in the concentration of iodine-containing compounds in the R.T.F., and this latter may or may not account for the reputed mucus-liquefying effect of iodides.

Potassium iodide, sodium iodide, and Iod-Ethamine were given by stomach tube to 54 rabbits and the concentration of alcohol-soluble and -insoluble blood iodine followed for a period up to 24 hr. Following all three iodides, there was a rise and fall in the values of both fractions of blood iodine, the values for the alcohol-soluble fraction rising to the higher levels but declining more rapidly than the values for the alcohol-insoluble fraction. Potassium iodide had the advantage over sodium iodide that after its use the peak levels of both fractions of blood iodine were maintained for a longer period of time. Iod-Ethamine had the advantage over potassium iodide that higher peak levels were reached with both fractions of blood iodine and, while not maintained for as long as after potassium iodide, these peak levels were held for several hours and for a longer period than following sodium iodide. The concentrations of blood iodine were of the same order or higher than those found in respiratory tract fluid following administration of the same dose of iodides, suggesting that the appearance of iodine-containing substances in respiratory tract fluid (R.T.F.) after iodide therapy is of the nature of a simple diffusion from blood.

Alumina refineries are among the leading sources of atmospheric air pollution with a wide range of pollutants hazardous to human respiratory organs. It is relevant to study and evaluate the occurrence of the risks for development of respiratory diseases in children living in the area affected by the emission components of an alumina refinery. We assessed air quality of the area under observation and comparison according to monitoring observations, risk of non-carcinogenic effects from the respiratory organs. The content of chemicals in the blood and urine adequate to risk factors was quantified. The structure of individual groups of respiratory diseases was analyzed. The causal relationships of violations of laboratory parameters with an increased content of chemicals in biological media were evaluated. It was found that an aerogenic exposure of chemical pollutants is formed on the territory with the production of metallurgical alumina. It determines the risk for development of respiratory diseases, exceeding an acceptable level up to 49.9 times. In the exposed children, the content of manganese, chromium, nickel, copper, xylenes, formaldehyde and aluminum, fluoride ion in the urine was increased to 4.2 times in relation to the indices in the comparison group. A high level of additional respiratory morbidity(1.8 times) was revealed. Chronic lymphoproliferative diseases of the nasopharynx and inflammatory diseases of the upper respiratory tract (up to 6.6 times more often), inflammatory diseases with a predominance of the mechanism of allergic inflammation ( up to 2.1 times more often)are more often detected in the framework of the respiratory diseases. Negative effects on the part of the respiratory system in the form of activation of antioxidant processes, the development of an inflammatory reaction, local, general and specific sensitization of the respiratory tract were established. It confirms the occurrence of the risks for the development of respiratory diseases in children in the exposure area of the chemical factors of alumina refinery-associated economic activity.

The nutritional quality of animal products is strongly related to their fatty acid content and composition. Nowadays, attention is paid to the possibility of producing healthier foods of animal origin by intervening in animal feed. In this field, the use of condensed tannins as dietary supplements in animal nutrition is becoming popular due to their wide range of biological effects related, among others, to their ability to modulate the rumen biohydrogenation and biofortify, through the improvement of the fatty acids profile, the derivate food products. Unfortunately, tannins are characterized by strong astringency and low bioavailability. These disadvantages could be overcome through the microencapsulation in protective matrices. With this in mind, the optimal conditions for microencapsulation of a polyphenolic extract rich in condensed tannins by spray drying using a blend of maltodextrin (MD) and gum Arabic (GA) as shell material were investigated. For this purpose, after the extract characterization, through spectrophotometer assays and ultra-high-performance liquid chromatography-quadrupole time-of-flight (UHPLC-QTOF) mass spectrometry, a central composite design (CCD) was employed to investigate the combined effects of core:shell and MD:GA ratio on the microencapsulation process. The results obtained were used to develop second-order polynomial regression models on different responses, namely encapsulation yield, encapsulation efficiency, loading capacity, and tannin content. The formulation characterized by a core:shell ratio of 1.5:5 and MD:GA ratio of 4:6 was selected as the optimized one with a loading capacity of 17.67%, encapsulation efficiency of 76.58%, encapsulation yield of 35.69%, and tannin concentration of 14.46 g/100 g. Moreover, in vitro release under varying pH of the optimized formulation was carried out with results that could improve the use of microencapsulated condensed tannins in animal nutrition for the biofortification of derivates.

Shrimp oil (SO) rich in n-3 fatty acids and astaxanthin, mixed with antioxidant-rich tea seed oil (TSO), was microencapsulated using mung bean protein isolate and sodium alginate and fortified into whole wheat crackers. SO and TSO mixed in equal proportions were emulsified in a solution containing mung bean protein isolate (MBPI) and sodium alginate (SA) at varied ratios. The emulsions were spray-dried to entrap SO-TSO in MBPI-SA microcapsules. MBPI-SA microcapsules loaded with SO-TSO showed low to moderately high encapsulation efficiencies (EE) of 32.26–72.09% and had a fair flowability index. Two selected microcapsules with high EE possessed the particle sizes of 1.592 and 1.796 µm with moderate PDI of 0.372 and 0.403, respectively. Zeta potential values were −54.81 mV and −53.41 mV. Scanning electron microscopic (SEM) images indicated that microcapsules were spherical in shape with some shrinkage on the surface and aggregation took place to some extent. Fourier transform infrared (FTIR) and differential scanning calorimetry (DSC) analyses of samples empirically validated the presence of SO-TSO in the microcapsules. Encapsulated SO-TSO showed superior oxidative stability and retention of polyunsaturated fatty acids (PUFAs) to unencapsulated counterparts during storage of 6 weeks. When SO-TSO microcapsules were fortified in whole wheat crackers at varying levels (0–10%), the crackers showed sensorial acceptability with no perceivable fishy odor. Thus, microencapsulation of SO-TSO using MBPI-SA as wall materials could be used as an alternative carrier system, in which microcapsules loaded with PUFAs could be fortified in a wide range of foods.

It has long been known, that nasal saline irrigation is a safe and effective method, which is routinely prescribed by otorhinolaryngologists to prevent and to treat a wide range of pathologies. There are a lot of publications on different irrigation techniques and methods. This literature review discusses the key parameters of nasal irrigation, including tonicity, pH, and the additional components, and explains how they affect the effectiveness of the procedure. The vast majority of available publications did not found any possible changes in the effectiveness of solutions with different pH close to neutral meaning. Whereas, the volume of the irrigated solution, increases the efficiency of the irrigation in direct proportion. Thus, the largest distribution area of the solute is noted when washing with a large volume of liquid. Nasal saline irrigation is an effective treatment option for patients with several acute and chronic diseases and for postoperative care after rhinosurgery. Moreover, nasal irrigation might be used as an effective non-specific method for prevention of acute upper respiratory tract infections. Irrigation of the nasal cavity reduces the mucus viscosity and promotes its faster elimination, along with pathogens fixed in it. Additionally, irrigation with isotonic saline solutions increases the hydration of the underlying water base, which enhances the frequency of ciliary beat and reduces the concentration of local inflammatory mediators. COVID-19 pandemic situation due to lack of any specific antiviral drugs dictates the necessity of an effective non-specific preventive option, which could be introduced worldwide. The so-called full volume lavage of the nasal cavity allows for better cleaning of the nasal cavity and effective moisturizing of the mucous membrane. It is the timely cleansing and moisturizing that are most important for maintaining the normal activity of the local protective mechanisms of the upper respiratory tract.

Background: Dysphania ambrosioides (L.) Mosyakin & Clemants is an aromatic herb native to South America, but also distributed widely throughout Africa and Europe. This plant is traditionally used to treat various ailments including, pain and swellings, flu, parasitic diseases, and as analgesic, antipyretic, and wound healing. Phytochemical analyses of D. ambrosioides revealed the presence of terpenoids, flavonoids, coumarins, fatty acids and miscellaneous compounds among others, which might be responsible for its modern pharmacological actions. Objective: The present work summarizes recent developments on phytochemistry, ethnomedicinal use, pharmacology, and toxicity of D. ambrosioides. A critical assessment of the literature information of D. ambrosioides is also presented. Methods: The available information on D. ambrosioides was collected through libraries and electronic databases [Scifinder, ACS, Scielo, Science direct, Pubmed (National Library of Medicine), Wiley, Springer, PROTA, Web of Science, Google Web, Yahoo search and Google scholar] from respective inception until january 2021. Results: More than 150 compounds, including terpenoids, flavonoids, coumarins, fatty acids, and miscellaneous compounds etc.. were identified from D. ambrosioides. D. ambrosioides exhibited a wide range of pharmacological activities, including antimalarial, anti-inflammatory, antiparasitic, anticancer, insecticidal, antigiardial, among others. Metal nanoparticles synthesized from D. ambrosioides extracts presented enhanced pharmacological activities as compared to the crude plant extracts counterparts. Conclusion: D. ambrosioides is a promising medicinal plant, however, more in vivo experiments, cytotoxicity tests, and mechanisms of actions of its extracts and compounds are recommended to transubstantiate the ethnomedicinal claims of this plant into scientific rationale-based information.

Abstract: Linum usitatissimum (Linn.), Commonly known as flaxseed or flaxseed, belongs to the family Linaceae. Flaxseed is a crop of blue flowers that produce small, flat seeds of golden yellow to reddish-brown color. It is a native of the Mediterranean and West Asia. Due to its health benefits associated with the high content of linolenic acid (ALA), flaxseed has played a major role in diet and research. The ALA is an essential omega-3-fatty acid, and also due to its presence a major lignan, i.e. secoisolaricyrcinol diglucoside (SDG). There is also a wide range of uses of flaxseed oil in skin health, anticoagulants, anticancer, ulcer treatment, muscle growth, and weight loss. The nutritional composition of flaxseed is about 30% carbohydrate, 18% protein, and 39% fat. Flaxseed contains most carbohydrates in the form of fiber and contains more than 45% omega-3 fatty acids. It also contains dietary fibers, proteins and polyunsaturated fatty acids. All the ingredients possess different health benefits. Although plant resources are the key ingredient in drug discovery, the popularity of flaxseed always fascinate scientists, the number of articles giving information about the chemical components of flaxseed and its potential clinical use is very little. This review provides a systematic summary of the research completed over the past decade and provides an up-to-date summary of the various bioactive and outlines the relationship between the nutritional and pharmacological use of chemical ingredients and its flaxseed.

Abstract Fatty acids determine the physical and chemical properties of fats. Animal fats, regardless of species, have more saturated and monounsaturated than polyunsaturated fatty acids. The major fatty acids in meat are palmitic (16:0), stearic (18:0), palmitoleic (16:1), oleic (18:1), linoleic (18:2), and linolenic (18:3) acids, among which oleic acid is the most predominant. Arachidonic acid (20:4 cis 5,8,11,14) is an essential fatty acid only found in animal fats and can be used as a quality control indicator in the fatty acid analysis. Fatty acid analysis has been traditionally performed by gas chromatography (GC) of volatile fatty acid derivatives, prominently the methyl esters, and flame ionization detection (FID), in which the carbon chain of fatty acids is degraded to the formylium ion CHO+. The FID is very sensitive and is the most widely used detection method for GC, providing a linear response, i.e., peak area, over a wide range of concentrations. Researchers have been used the FID peak area to calculate the percentages of fatty acids. However, the FID is a “carbon counter” and relies on the “equal per carbon” rule; therefore, at the same molar concentration, fatty acids with a different number of carbons produce different peak areas. The recent development of mass spectrometry technology has improved the specificity of fatty acid detection. Specific target and qualifier ions provide better identification and more accurate quantification of fatty acid concentrations. Although fatty acids can be identified through comparing ion fragmentation with various databases, authentic standards are needed for quantification purposes. Using mass spectrometry, more than 50 fatty acids have been identified in meat samples. Some branched-chain fatty acids may have flavor, safety, and shelf life implications in meat products.
