Non-conventional nixtamalized maize flours elaborated by a factory in Mexico were used for tortilla preparation. Tortillas were stored at 4°C for up to 72 h and the total starch, available starch, resistant starch and retrograded resistant starch were assessed. The traditional white tortilla, used as a control, showed higher protein and fat contents than blue maize tortilla, whereas a maize-bean m

In vitro indicators of starch bioavailability were evaluated in freshly prepared maize tortillas and compared to those exhibited by 24, 48 or 72 h-stored samples. Storage took place either at room temperature (approx. 25 °C) or under refrigeration (4 °C). Potentially available starch (AS) content decreased from 670 g kg-1 in the control tortilla to 583 g kg-1 in 72 h-stored preparations. Concomita

Tortilla samples were elaborated by four small commercial factories in Mexico, employing masas prepared with the traditional nixtamalization process. Samples were stored at 4°C for up to 72 hours and their chemical composition and in vitro starch digestibility features were evaluated. Chemical composition did not change with the storage time, but soluble carbohydrates decreased slightly during sto

In spite of the importance of legumes in Latin American diets, nutritional features of carbohydrates in these seeds are scarcely known. The purpose of this study was to assess the in vitro digestibility of starch in cooked powdered black beans, a common type of product in Mexico and Central America. The properties of a commercial product were compared to those of an experimental material obtained

Common beans of the Mayocoba variety were cooked (178 min) and evaluated regarding their chemical composition and starch digestibility in vitro. Mean physical characteristics of the Mayocoba grain were: thousand-kernel weight, 443.0 (±0.98)g; length, 12.45mm; width 7.84mm and thickness, 6.44mm. Total starch content in Mayocoba bean was 40.24% (dmb). The available starch was 22.87%, whereas resista

People in the rural areas of Mexico consume corn tortillas and beans as basic components of their diet. However, little is known about the nutritionally relevant features of starch present in such combined meals. The objective of the present study was to evaluate the in vitro bioavailability of starch in tortilla-bean mixtures stored at 4 °C for different times, as compared to that of corn tortill

Powdered preparations enriched in resistant starch (RS) were obtained from native and lintnerized (prolonged acid treatment) banana starches by consecutive autoclaving/cooling treatments. The preparations were tested for indigestible starch content, swelling and solubility properties, thermal analysis and pasting profile. The autoclaved samples had higher RS content than their parental counterpart

"Ayocote" beans (Phaseolus coccineous) were cooked and studied regarding their chemical composition and in vitro starch digestibility. Protein and ash contents were 20.46 and 1.39%, respectively, which are among the lowest levels for seeds of the Phaseolus genus. On the contrary, lipid content was relatively high (3.31%). Available starch (AS) values decreased with storage at 4°C, changing from 37

In Mexico, consumption of beans represents 15% of the normal diet of the population in rural zones. Four common bean varieties cultivated in Mexico were studied regarding their chemical composition, starch digestibility and indigestible fraction. The protein level in the samples Huasteco, Tacana and TLP 19 was not different (α = 0.05), but Veracruz cultivar had the highest protein and ash content,

Nixtamalized maize flours elaborated by four factories in Mexico were used for tortilla preparation. Samples were stored at 4°C for up to 72 h and their in vitro starch digestibility features were evaluated. Moisture content was different between flour and tortilla but no evident relation could be established. Protein and lipid levels were lower in tortillas than in flour but ash content was not d

Five common bean varieties were cooked and studied regarding starch digestibility. Cooking time of different cultivars ranged between 2.55 and 5.92 h. Available starch (AS) values decreased with the storage time and the bean sample that had the lowest AS content (control sample, without storage) showed the shortest cooking time. A similar pattern was found for resistant starch (RS); the varieties

Banana starch was isolated and used for preparation of two types of cookies. Chemical composition and digestibility tests were carried out on banana starch and the food products, and these results were compared with corn starch. Ash, protein, and fat levels in banana starch were higher than in corn starch. The high ash amount in banana starch could be due to the potassium content present in this f

Mercury was measured onboard the IAGOS-CARIBIC passenger aircraft from May 2005 until February 2016 during near monthly sequences of mostly four intercontinental flights from Germany to destinations in North and South America, Africa and South and East Asia. Most of these mercury data were obtained using an internal default signal integration procedure of the Tekran instrument but since April 2014

Background: Scavenger receptor BI (SR-BI) is a classic high-density lipoprotein (HDL) receptor, which mediates selective lipid uptake from HDL cholesterol esters (HDL-C). Apolipoprotein M (ApoM), as a component of HDL particles, could influence preβ-HDL formation and cholesterol efflux. The aim of this study was to determine whether SR-BI deficiency influenced the expression of ApoM. Methods: Bloo

Consumers appreciate leafy green vegetables such as baby leaves for their convenience and wholesomeness and for adding a variety of tastes and colors to their plate. In Western cuisine, leafy green vegetables are usually eaten fresh and raw, with no step in the long chain from seed to consumption where potentially harmful microorganisms could be completely eliminated, e.g., through heating. A conc

Background: Chronic subdural hematoma (CSDH) is one of the most common neurosurgical conditions. Patients diagnosed with CSDH’s are often planned for subacute surgery. This means that time from diagnostic CT scan until actual surgery might often be prolonged. There are no previous studies that highlight the effect of delayed intervention in this population. Method: Patients that underwent surgical

Background: Diabetes mellitus is linked to premature mortality of virtually all causes. Furin is a proprotein convertase broadly involved in the maintenance of cellular homeostasis; however, little is known about its role in the development of diabetes mellitus and risk of premature mortality. Objectives: To test if fasting plasma concentration of furin is associated with the development of diabet

This post hoc analysis from a multicenter study (NCT01674634) was designed to evaluate the efficacy of collagenase Clostridium histolyticum (CCH) treatment in patients with different stages of Dupuytren contracture. Previously untreated patients who received two concurrent injections of CCH in two affected joints in the same finger were assessed by disease severity (Tubiana stage). The mean (SD) i

We prove bounds for the almost sure value of the Hausdorff dimension of the limsup set of a sequence of balls in Rd whose centres are independent, identically distributed random variables. The formulas obtained involve the rate of decrease of the radii of the balls and multifractal properties of the measure according to which the balls are distributed, and generalise formulas that are known to hol
