Abstract:

Pharmaceutical research on oral drug delivery, particularly on the gastro-retentive drug delivery system known as the Floating Drug Delivery System (FDDS), has attracted a lot of interest from the pharmaceutical industry. GRDF stands for gastro-retentive dosage forms, which are dosage forms that can be retained in the stomach. With the help of GRDFs, the drug can be released to the upper portion of the GIT more continuously and for a longer period of time. This improves the bioavailability of drugs with limited therapeutic windows, lengthening the time between doses and enhance patient complia

Abstract:

The purpose of the present study was to elucidate the rate of water absorption of an oral rehydration solution containing partially hydrolyzed guar gum (PHGG) in the small intestine, which is the main site of water absorption when water is drunk. Seven-week-old male SD rats were employed. We prepared four types of an aqueous solution, i.e., containing mineral and sugar, containing PHGG, containing mineral and sugar and PHGG, or containing no additives. After 24 h of food and 4 h of water deprivation, the aqueous solutions were infused into the stomach of conscious rats on their hands using a s

Abstract:

Micronutrient deficiencies are relatively common, in particular iron and cobalamin deficiency, and may potentially lead to life-threatening clinical consequences when not promptly recognized and treated, especially in elderly patients. The stomach plays an important role in the homeostasis of some important hematopoietic micronutrients like iron and cobalamin, and probably in others equally important such as ascorbic acid, calcium, and magnesium. A key role is played by the corpus oxyntic mucosa composed of parietal cells whose main function is gastric acid secretion and intrinsic factor produ

Abstract:

Gastric emptying is a complex process, one that is highly variable and that makes in vivo performance of drug delivery systems uncertain. A controlled drug delivery system with prolonged residence time in the stomach can be of great practical importance for drugs with an absorption window in the upper small intestine. The main limitations are attributed to the inter- and intra-subject variability of gastro-intestinal (GI) transit time and to the non-uniformity of drug absorption throughout the alimentary canal. Floating or hydrodynamically controlled drug delivery systems are useful in such ap

Abstract:

The objective of this study is to demonstrate the potential of a multicompartmental mathematical model to simulate the activity of the gastrointestinal system after the intake of drugs, with a limited number of parameters. The gastrointestinal system is divided into five compartments, modeled as both continuous systems with discrete events (stomach and duodenum) and systems with delay (jejunum, ileum, and colon). The dissolution of the drug tablet occurs in the stomach and is described through the Noyes–Whitney equation, with pH dependence expressed through the Henderson–Hasselbach relationshi

<em>Esomeprazole is a BCS 11 compound, proton pump inhibitor used in the treatment of gastric, duodenal ulcer. The half-life of the drug is 4 hour. The drug has poor stability in acidic condition of the stomach. So, it is formulated into small sized and efficient carriers: the microspheres. To improve their residence time, bioadhesive characteristics can be coupled to develop mucoadhesive microspheres. Mucoadhesive microspheres are extensively used in targeted drug delivery due to their advantages like efficient absorption and improved bioavailability of the drugs and a much more intimate cont

This article reviews physicochemical aspects of calcium absorption from foods. Notable differences are observed between different food products in relation to calcium absorption, which range from <10% to >50% of calcium in the foods. These differences can be related to the interactions of calcium with other food components in the food matrix, which are affected by various factors, including fermentation, and how these are affected by the conditions encountered in the gastrointestinal tract. Calcium absorption in the intestine requires calcium to be in an ionized form. The low pH in the s

Abstract:

Gastro retentive drug delivery system is one of the approaches to achieve controlled drug delivery. The gastro retentive drug delivery system is a way to prolong residence time of active pharmaceutical ingredient in gastrointestinal tract. It is also applied for targeting drug in upper gastrointestinal tract for generating local and systemic effect. Controlled drug delivery creates a window of absorption that release drug for a longer duration of time before reaching absorption site. Gastro retentive drug delivery systems have gained wide variation of oral drug distribution in the area of late

Abstract:

An experimental and numerical study of the nonlinear optical properties of hibiscus sabdariffa in gelite bloom is shown. Using the Z-scan technique and a λ = 477 nm cw variable power Ar laser, nonlinear absorption was measured, which is the main contribution to the nonlinear refractive index. Hibiscus sabdariffa presents large phase changes at low powers, which causes spatial self-phase modulation (SSPM) effects. Our experimental results show a high agreement with the numerical model of thermal lens formation used.

Abstract:

3-Chloropropane-1,2-diol (3-MCPD) esters are food processing contaminants, and are known to be potentially carcinogenic. The main purpose of this study was to determine whether the emulsion technique increases the absorption of this contaminant, and to develop strategies to reduce their absorption. 3-MCPD ester contents in edible oils (hazelnut, walnut, sunflower, soybean, corn, and olive oil) were determined. Refined olive oil contained the highest 3-MCPD ester level (1.7749 ± 0.1262 mg/kg). Then, emulsions (fine, medium, coarse) were prepared with 0.15-2% emulsifier (whey protein isolate) an

Abstract:

Despite active research, the mechanism by which food is transported, mixed and absorbed in the human gastro-intestinal tract remains poorly understood. At the University of Iowa Veterans Hospital, clinicians have been treating veterans for abnormal mechanical activity of the stomach and intestine and are pursuing research into such mechanisms, in order to better control and treat such ailments. The pathology experienced by these patients tends to be chronic and somewhat refractory to treatment particularly in the elderly, those with diabetes or after abdominal operations. Abnormal activity is

Abstract:

Food is an essential to our existence but under certain conditions it could become the origin to the accumulative health damages. Technological processes as heating, chopping, mincing, grounding, promote the lipid oxidation process in muscle tissues and meat foodstuffs. Lipid oxidation occurred rapidly in turkey muscle, intermediate in duck, and slowest in chicken during frozen storage. Depletion of tocopherol during frozen storage was more rapid in turkey and duck compared to chicken. These processes developed from lipid peroxides produce many cytotoxic compounds including malondialdehyde (MD

Currently, climate change and global warming are the main issues on environmental concern due to the higher amount of carbon dioxide in the atmosphere. The main sources of carbon dioxide are energy-related activities such as power generation. Now, the effective technology to remove CO₂ from these sources is absorption especially with amine solution. The commercially used amine solutions are monoethanolamine (MEA) and methyldiethanolamine (MDEA). Nevertheless, they also have disadvantages such as low capacity, corrosion and high energy requirement. Therefore, many new solvents have been develop

Abstract:

This paper provides an estimation of the size of income and demand automatic stabilizers in a representative sample of Latin American and Caribbean (LAC) countries. The authors find that when a negative unemployment shock hits the economy, the size of income and demand automatic stabilizers coefficients is much smaller than the size of these coefficients in Europe and the United States. This evidence suggests that there is room for policies that can enlarge the absorption by these coefficients as a way to contribute to macroeconomic stability in LAC countries.

In both cases, the principal idea was to design and operate a dedicated air collection system that would be used for the treatment of the gases, and that would work independently from the general ventilation system. The advantages envisaged: (1) if collected at a point close to the source of generation, pollutants would

Abstract:

The special concentrically braced frame (SCBF) is an aseismic structure, but its bracing system exhibits brittle failure and premature buckling connected with the weld fracture of the gusset plate and the post-buckling of the braces; thus, maximizing the role of energy dissipation is difficult. Here, this paper proposes a system of double-tube buckling-restrained brace with cast steel connectors for steel SCBFs. The large inelastic deformation of the bracing system is mainly concentrated in the ductile cast connectors under the earthquake, and the degree of buckling and post-buckling of braces
