High-intensity ultrasound as pre-treatment in the development of fermented whey and oat beverages: effect on the fermentation, antioxidant activity and consumer acceptance.

This study aimed to evaluate the effect of high-intensity ultrasound as pre-treatment in the development of fermented whey and oat beverages. Oat malt was produced, incorporated into a whey formulation (35, 50 and 65% v/v of whey) and ultrasonicated (at 40 kHz and 11 W/cm) for 0, 3 or 10 min, prior to fermentation with 431. The treatments were identified as 35/65/0, 50/50/0, 65/35/0, 35/65/3, 50/50/3, 65/35/3, 35/65/10, 50/50/10 and 65/35/10, referring to the whey percentage, oat percentage, and the ultrasound time (min), respectively.

Inhibitory effect of saccharides and phenolic compounds from maize silks on intestinal α-glucosidases.

Maize silks have been used in Mexico for centuries as a natural-based treatment for various illnesses, including obesity and diabetes. It has been shown in mice that intake of maize silk extracts reduces the levels of blood glucose. However, it is not clear how or what maize silk compounds are involved in such an effect.

Legume Proteins as a Promising Source of Anti-Inflammatory Peptides.

Legume proteins are precursors of bioactive components, such as peptides. In the present paper, different types of legume as sources of bioactive peptides and hydrolysates are considered and discussed based on their anti-inflammatory effect. Peptides with anti-inflammatory activity were included from in vitro and in vivo studies.

Effect of pulsed ultrasound on the physicochemical characteristics and emulsifying properties of squid (Dosidicus gigas) mantle proteins.

Food technologists are always looking to improve the functional properties of proteins. In this sense, in last years ultrasound has been used to improve some functional properties. For this reason, and considering that jumbo squid is an important fishery in northwest Mexico, the purpose of this research was to determine the effect of pulsed ultrasound on the physicochemical characteristics and emulsifying properties of squid (Dosidicus gigas) mantle proteins.

Short communication: Potential of Fresco-style cheese whey as a source of protein fractions with antioxidant and angiotensin-I-converting enzyme inhibitory activities.

Recently, traditional Mexican Fresco-style cheese production has been increasing, and the volume of cheese whey generated represents a problem. In this study, we investigated the chemical composition of Fresco-style cheese wheys and their potential as a source of protein fractions with antioxidant and angiotensin-I-converting enzyme (ACE)-inhibitory activities. Three samples from Fresco, Panela, and Ranchero cheeses whey were physicochemically characterized.

Warthin's tumors and their relationship to lung cancer.

Warthin's tumors (WT) are frequently encountered in clinical practice and can be easily mis-identified. To date, there has been no proven association between WT and lung cancer. A retrospective chart review was conducted of records from 2008 to 2013 in the University of Pennsylvania Health System.

Antihypertensive and hypolipidemic effect of milk fermented by specific Lactococcus lactis strains.

The antihypertensive and hypolipidemic effects of milk fermented by specific Lactococcus lactis strains in spontaneously hypertensive rats (SHR) were investigated. The SHR were fed ad libitum milk fermented by Lc. lactis NRRL B-50571, Lc.

Hypotensive and heart rate-lowering effects in rats receiving milk fermented by specific Lactococcus lactis strains.

Previous studies have demonstrated that milk fermented by specific Lactococcus lactis strains significantly inhibits the activity of angiotensin I-converting enzyme (ACE). However, the relationship between the ACE inhibitor and its in vivo action has revealed discrepancies. Therefore, the aim of the present study was to investigate the antihypertensive and heart rate (HR)-lowering effect of milk fermented by specific L.

Novel angiotensin I-converting enzyme inhibitory peptides produced in fermented milk by specific wild Lactococcus lactis strains.

The ability of specific wild Lactococcus lactis strains to hydrolyze milk proteins to release angiotensin I-converting enzyme (ACE) inhibitory peptides was evaluated. The peptide profiles were obtained from the <3 kDa water-soluble extract and subsequently fractionated by reversed-phase HPLC. The fractions with the lowest half-maximal inhibitory concentration estimated values (peptide concentration necessary to inhibit ACE activity by 50%) were Lc.

Angiotensin-converting enzyme inhibitory activity of milk fermented by wild and industrial Lactococcus lactis strains.

Angiotensin I-converting enzyme inhibitory (ACEI) activity was evaluated and compared in <3 KDa water-soluble extracts (WSE) isolated from milk fermented by wild and commercial starter culture Lactococcus lactis strains after 48 h of incubation. The highest ACEI activities were found in WSE from milk inoculated with wild L. lactis strains isolated from artisanal dairy products and commercial starter cultures.

Phenotypic and genotypic characteristics of Lactococcus lactis strains isolated from different ecosystems.

Lactococcus lactis is the lactic acid bacteria most used in the manufacture of dairy products because of its fast lactose fermentation and flavor production. In this study, L. lactis strains isolated from different sources and previously characterized and evaluated for their capability to produce flavor were compared with respect to their phenotypic and genotypic characteristics.

[Sociodemographic profile of a group of sex workers in Puerto Rico].

This research explored the sociodemographic characteristics, the health perceptions and the distinctive aspects of the sexual work of a group of women sexual workers (n = 311). The study interest was generating data relative to the use of injectable drugs, the prevalence of sexually transmitted diseases (STD), the prevalence of HIV and the risk behaviors of this population group. A remarkable characteristic of the group of women studied was their history of pregnancies at and early age.

[Women and health in numbers. Puerto Rico, 1994].

The purpose of this study was to explore the health situation of women in Puerto Rico through the analysis of the causes of deaths in medical certification contained in death certificates. The data source used was the computer tape containing the data on deaths occurred in Puerto Rico during 1994. This tape was produced by the Puerto Rico Department of Health.
