Caries correlates strongly to salivary levels of MMP-8.

Author(es): Hedenbjörk-Lager A; Bjørndal L; Gustafsson A; Sorsa T; Tjäderhane L; Akerman S; Ericson D
Source: Caries Res; 49(1): 1-8, 2015.
MEDLINE - International Literature
Language: English
: Journal Article
Abstract: The caries process in dentin involves the degradation of both mineral and organic matrix. The demineralization has been demonstrated to be caused by bacterial acids. However, the collagen degradation is considered to be initiated by endogenous proteolytic enzymes, mainly collagenolytic matrix metalloproteinases (MMPs). This paper aims to relate salivary MMP-8 (or salivary collagenase-2) and tissue inhibitor of MMP (TIMP-1) levels to manifest caries in a large number of subjects. A random sa (more)

Abstract: Since ancient times, herbs have been used as natural remedies for curing many physiological disorders. Traditional medicinal literature appreciated their value as nature's gift to mankind for the healing of illnesses. Some of the herbs have also been used for culinary purposes, and few of them have been used in cheese manufacture both as coagulating agents and flavor ingredients. Scientific investigations regarding biological activity and toxicity of chemical moieties present in many herbs (more)

Abstract: Maize, in addition to being the main staple food in many countries, is used in the production of hundreds of products. It is rich in compounds with potential benefits to health, such as carotenoids, phenolic compounds, vitamin E, and minerals that act as cofactors for antioxidant enzymes. Many of these compounds have been neglected thus far in the scientific literature. Nevertheless, deficiencies in the precursors of vitamin A and some minerals, such as iron and zinc, in maize, in associati (more)

Using sensory properties of food to trigger swallowing: a review.

Author(es): Loret C
Source: Crit Rev Food Sci Nutr; 55(1): 140-5, 2015 Jan 2.
MEDLINE - International Literature
Language: English
: Journal Article
Abstract: The effect of food consistency on swallowing function has been widely studied, and it is well recognized that by delaying the flow of the food bolus, thickened liquids can help in the management of swallowing dysfunction. However, fewer studies have been carried out on the impact of food sensory properties and related liking on swallowing function. This paper reviews the role of taste, olfaction, and trigeminal perceptions on swallowing function and highlights the need for a deeper investigation of this aspect of patient diet modification.

Simple sequence repeat markers in genetic divergence and marker-assisted selection of rice cultivars: a review.

Author(es): Kaur S; Panesar PS; Bera MB; Kaur V
Source: Crit Rev Food Sci Nutr; 55(1): 41-9, 2015 Jan 2.
MEDLINE - International Literature
Language: English
: Journal Article
Abstract: Sequencing of rice genome has facilitated the understanding of rice evolution and has been utilized extensively for mining of DNA markers to facilitate marker-assisted breeding. Simple sequence repeat (SSR) markers that are tandemly repeated nucleotide sequence motifs flanked by unique sequences are presently the maker of choice in rice improvement due to their abundance, co-dominant inheritance, high levels of allelic diversity, and simple reproducible assay. The current level of genome co (more)

Abstract: Onion (Allium cepa L.) is found in various regions of Europe, North America, Asia, and Africa. It is one of the classic examples of Allium species used not only for culinary preparations but also for medicinal purposes. Onion with a variety of purposes is often used as a raw material in many dishes and accepts almost all of the traditions and culture. Owing to its storage characteristics and durability of shipping, onions have been traded more widely than most vegetables. The pungent fracti (more)

Abstract: Wheat forms the basic ingredient for various bakery and traditional products. Wheat-based flat breads are one of the traditional products prepared in different parts of the world. Different regions of the world have inherited different preparation methods since time immemorial, which has led to the existence of traditional flat breads'. Being traditional, only a few have been extensively studied scientifically. India, being the second largest producer of wheat, has a great saga of tradition (more)

Abstract: Meat is one of the most imperative protein sources available with respect to its production and consumption. It is the richest source of some valuable nutrients like proteins, essential amino acids, polyunsaturated fatty acids, vitamins, and minerals like iron, zinc, and selenium. Thermal treatment produces conformational changes in protein structure as well as flavor, texture, and appearance, and chemical properties of the ingredients are also changed.

Source: Prep Biochem Biotechnol; 45(1): 18-32, 2015 Jan 2.
MEDLINE - International Literature
Language: English
: Journal Article
Abstract: Milk protein of farm animals is difficult to isolate because of the presence of casein micelles, which are hard to separate from whey by using centrifugation or filtration. Insoluble casein micelles also create an obstacle for purification instruments to operate efficiently. The conventional method, to precipitate caseins by lowering pH to 4.6 and then recover the whey fraction for further purification using chromatography techniques, is not applicable to proteins having an isoelectric poin (more)

Abstract: In this study, a simple purification protocol is developed to reduce the bovine serum albumin (BSA) content in commercially available bovine submaxillary mucin (BSM). This involved purification of the BSM by one-column anion-exchange chromatography protocol resulting in BSM with greatly reduced BSA content and homogeneously distributed size, and in a high yield of ∼43% from BSM as received from the manufacturer. The purity and composition of commercially acquired BSM were assessed by s (more)
