Promotion of Pregnant Merino Ewes' Welfare with the Introduction of a Drought- and High-Temperature-Resistant Cereal into Their Diet: Analysis of Tritordeum Meadow.

Tritordeum is a new cereal resistant to drought and high temperatures, and it is a very healthy crop. The aim of this study was to compare two different diets (tritordeum meadow vs. oat meadow) for grazing pregnant ewes to determine if there was any effect on the objective physiological indicators of animal welfare.

Synthesis, Biological Evaluation, and Docking Studies of Open-Chain Carbohydrate Amides as Acetylcholinesterase Inhibitors.

Introduction: Alzheimer's disease is a multifactorial syndrome, which is not yet fully understood, causing memory loss, dementia, and, ultimately, death. Acetylcholinesterase inhibitors are the mainstay drugs that are used in disease-symptomatic treatment. In this work, we report a new synthetic route yielding sugar amides as low to moderate acetylcholinesterase inhibitors.

A Study on the Influence of the Use of Sulphur Dioxide, the Distillation System and the Aging Conditions on the Final Sensory Characteristics of Brandy.

Brandy is a unique alcoholic beverage obtained from wine distillates. Numerous studies have been published on its physicochemical traits and the effect of certain elaboration variables on them, but not many studies have been carried out from a sensory point of view or that have followed standardized methods applicable to this discipline. This study intends to determine the effect that certain production variables have on the sensory characteristics of brandy.

A Theoretical Approximation of the Accelerating Effects of Ultrasound about the Extraction of Phenolic Compounds from Wood by Wine Spirits.

The acceleration on the extraction by the sonication of phenolic compounds (measured as the Total Phenolic Index) from wood chips by wine distillates is studied in the present paper. Using the Arrhenius equation, the theoretical temperature at which the kinetics obtained by these sonicated extraction processes are equal to the kinetics of non-sonicated and thermally accelerated extractions, was calculated. By applying a pseudo-second order kinetic model, it was shown that the initial rate values obtained from the sonicated extractions were as high as those obtained from the thermal extractions carried out at a temperature at least 2.

Analytical and Chemometric Characterization of Fino and Amontillado Sherries during Aging in System.

Fino and Amontillado are Sherry wines, produced in area (southern Spain), and aged in system. Fino Sherry wine follows a biological aging process, under a veil of flor yeasts, while Amontillado Sherry wine shares the same biological aging firstly, followed by oxidative aging, which gives them special features. Organic acids, esters, higher alcohols, phenolic compounds and total dry extract of Sherries evolve during aging due to evaporation processes, physical-chemical reactions, wood contributions and microbiological activity.

Aroma of Sherry Products: A Review.

Jerez (Sherry) is a well-known wine-producing region located in southern Spain, where world-renowned oenological products such as wines, vinegars, and brandies are produced. There are several factors that provide characteristic physical, chemical, and sensory properties to the oenological products obtained in this Sherry region: the climate in the area with hot summers, mild winters, and with limited rainfall; the raw material used consisting on Palomino Fino, Moscatel, and Pedro Ximénez white grape varieties; the special vinification with fortified wines; and aging techniques such as a dynamic system of biological or oxidative aging. These special organoleptic characteristics are responsible for, among others, the aromatic profile of the wines, vinegars and brandies from the area, which explains why this is a subject that has been extensively researched over the years.

HPLC-DAD-MS and Antioxidant Profile of Fractions from Amontillado Sherry Wine Obtained Using High-Speed Counter-Current Chromatography.

In the present work, the polyphenolic profile of a complex matrix such as Amontillado sherry has been processed by means of high-speed counter-current chromatography (HSCCC) and characterized by HPLC-DAD-MS. An Amberlite XAD-7 column was used to obtain the wine extract, and three different biphasic solvent systems were applied for HSCCC separation: MTBE (methyl -butyl ether)/n-butanol/acetonitrile/water (1.1/3/1.

Bull horn injuries. A 40-year retrospective study with 572 patients.

Background: Although bullfighting festivals were traditionally attributed to the cultural idiosyncrasies of the Ibero-American people, they also exist world-wide.

Methods: A retrospective study was conducted, reviewing the medical records of patients treated on our service for bull horn injuries between January 1978 and December 2019.

Results: There were 572 admissions due to bull horn injuries.

Synthesis of β-galactosylamides as ligands of the peanut lectin. Insights into the recognition process.

The synthesis of mono and divalent β-galactosylamides linked to a hydroxylated chain having a C2 symmetry axis derived from l-tartaric anhydride is reported. Reference compounds devoid of hydroxyl groups in the linker were also prepared from β-galactosylamine and succinic anhydride. After functionalization with an alkynyl residue, the resulting building blocks were grafted onto different azide-equipped scaffolds through the copper catalyzed azide-alkyne cycloaddition.

Genetic basis of unstable expression of high gamma-tocopherol content in sunflower seeds.

Background: Tocopherols are natural antioxidants with both in vivo (vitamin E) and in vitro activity. Sunflower seeds contain predominantly alpha-tocopherol (>90% of total tocopherols), with maximum vitamin E effect but lower in vitro antioxidant action than other tocopherol forms such as gamma-tocopherol. Sunflower germplasm with stable high levels of gamma-tocopherol (>85%) has been developed.

Demographic and clinical features of adolescents and young adults with alcohol-related disorders admitted to the psychiatric emergency room.

Objectives: To determine the incidence of alcohol related problems (ARP) among adolescents admitted to the Psychiatric Emergency Room (PER) and to describe the demographic and clinical characteristics.

Methods: The study was a retrospective review of admissions to the PER, where we reviewed the psychiatric records of all of the 14-30 year olds admitted to the PER during the three-month period between April 1st, 2003 and June 30th, 2003. Demographic and clinical data of subjects with and without ARP were compared.

Bradycardia related to hypoglycaemia.

Alterations in blood glucose levels are known to be involved in electrocardiogram changes. Various types of arrhythmias have been reported. We present here the case of an 81-year-old woman presenting with transient atrial fibrillation while being treated for hypoglycaemia with dextrose infusion, and finally developing a sinus rhythm.
