Purpose: We investigated the relationship between oral frailty (OFr) and falls among long-term care residents.
Methods: Residents (N = 254, mean age 84 y, 79% women) participated in this longitudinal cohort study in 2018-2021. OFr was defined by six signs.
Purpose: We evaluated oral frailty (OFr) and its association with health-related quality of life (HRQoL), energy and protein intake, and survival among older long-term care residents.
Methods: This cross-sectional study with a 3-year follow-up for survival assessed 349 residents in long-term care facilities (73% female, mean age 82 years). We defined OFr with six signs (dry mouth, food residue on oral surfaces, unclear speech, inability to keep mouth open or pain expression during the clinical oral examination, diet pureed/soft) and OFr severity was categorized as Group 1, (mild) = 0-1 signs, Group 2 (moderate) = 2-4 signs, and Group 3 (severe) = 5-6 signs.
Most new small drug molecules in pharmaceutical development require improvement of solubility. The controlled expansion of supercritical solutions (CESS®) process is a nanoparticle production technology, dedicated to enhancing the dissolution rate of active pharmaceutical ingredients (APIs) suffering from poor solubility and enabling novel drug delivery opportunities. In this process, the API is dissolved in supercritical carbon dioxide (scCO) and nanoparticles are formed through controlled pressure reduction.

Promising oleogels are unstable during storage, and to improve their stability careful control of the crystalline network is necessary. However, this is unattainable with state-of-the-art technologies.

The results of micronutrient dilution studies in older people have been few and conflicting. We examined the nutritional status and nutrient intakes associated with nonmilk extrinsic sugars (NMES) intakes in older people representing a broad spectrum of both healthy and vulnerable older populations.

The aim of this study was to examine how older people's energy and nutrient intakes are associated with the MNA and to determine how sensitive and specific MNA is in identifying those having low energy and protein intakes.
Materials And Methods: This cross-sectional study combined data from five nutritional studies (N=900): both home-dwelling and institutionalized older people without and with disabilities.
Objective: The aim was to examine the effect of tailored nutritional guidance on nutrition, health-related quality of life (HRQoL) and falls in persons with Alzheimer disease (AD).
Design: Randomised controlled trial.
Setting And Participants: Persons with AD living with a spouse.

Background: Malnutrition is associated with comorbidities and functional decline among older people. Less is known about nutrient intakes across heterogeneous older populations.
Objective: We examined nutritional status and nutrient intakes in different samples of older people representing broad spectrum of healthy and frail populations.
Objectives: To describe the process and feasibility of our randomised, controlled intervention study (NuAD trial) that positively affected the nutrition and quality of life, and prevented falls of home-dwelling persons with Alzheimer disease (AD).
Design, Setting, Participants: This qualitative study comprised 40 persons with AD and spousal caregivers of our trial. Our intervention during one year involved tailored nutritional guidance for these couples.
Objective: Alzheimer patients (AD) are known to be at risk for malnutrition and their older spouses may also have nutritional problems. The aim of our study was to clarify the association of caregivers' sex on the nutrient intake of AD couples.
Setting: Our study uses the baseline data of a randomized nutritional trial exploring the effectiveness of nutrition intervention among home-dwelling AD patients.

Fibres fractionated from solid recovered fuel (SRF), a standardised market combustion fuel produced from sorted waste, were considered as a source of lignocellulosic fermentable sugars. The fibre yield from four samples of SRF was 25-45%, and the separated material consisted of 52-54% carbohydrates, mainly glucan, with a high content of ash (12-17%). The enzymatic digestibility of recovered fibres was studied at low and high solids loading and compared with model substrates containing only chemical and mechanical pulps.

Optimal enzyme mixtures of six Trichoderma reesei enzymes and five thermostable enzyme components were developed for the hydrolysis of hydrothermally pretreated wheat straw, alkaline oxidised sugar cane bagasse and steam-exploded bagasse by statistically designed experiments. Preliminary studies to narrow down the optimization parameters showed that a cellobiohydrolase/endoglucanase (CBH/EG) ratio of 4:1 or higher of thermostable enzymes gave the maximal CBH-EG synergy in the hydrolysis of hydrothermally pretreated wheat straw. The composition of optimal enzyme mixtures depended clearly on the substrate and on the enzyme system studied.

Irreversible binding of enzymes to the residual substrate prevents their reuse and no efficient methods for recycling of enzymes have so far been presented. Cellulases without a carbohydrate-binding module (CBM) have been found to act efficiently at high substrate consistencies and to remain non-bound after the hydrolysis.

Therefore, understanding of enzyme-lignin interactions is essential for the development of enzyme mixtures and processes for lignocellulose hydrolysis. We have studied cellulase-lignin interactions using model enzymes, Melanocarpus albomyces Cel45A endoglucanase (MaCel45A) and its fusions with native and mutated carbohydrate-binding modules (CBMs) from Trichoderma reesei Cel7A.

Objectives: The aim was to assess the nutritional status and food intake of home care receivers and improve their nutrient intake with tailored nutritional advice administered via videoconferencing.
Background: Nutritional status often deteriorates in Alzheimer's disease (AD). Less is known about whether nutritional care reverses malnutrition and its harmful consequences in AD. The aim of this study is to examine whether individualized nutritional care has an effect on weight, nutrition, health, physical functioning, and quality of life in older individuals with AD and their spouses living at home.

For cost-efficient use of enzymes in large-scale industrial applications, high-level expression of enzymes in recombinant hosts is usually a prerequisite. The main aim of the present study was to compare the biochemical and hydrolytic properties of two thermostable recombinant glycosyl hydrolase families 10 and 11 (GH10 and GH11, respectively) xylanases with respect to their potential application in the hydrolysis of lignocellulosic substrates.
View Article and Find Full Text PDFBackground: Thermostable enzymes have several benefits in lignocellulose processing. In particular, they potentially allow the use of increased substrate concentrations (because the substrate viscosity decreases as the temperature increases), resulting in improved product yields and reduced capital and processing costs. A short pre-hydrolysis step at an elevated temperature using thermostable enzymes aimed at rapid liquefaction of the feedstock is seen as an attractive way to overcome the technical problems (such as poor mixing and mass transfer properties) connected with high initial solid loadings in the lignocellulose to ethanol process.

The enzymatic properties were studied and are reported here for family 7 cellobiohydrolases from the thermophilic fungi Acremonium thermophilum, Thermoascus aurantiacus, and Chaetomium thermophilum. The Trichoderma reesei Cel7A enzyme was used as a reference in the experiments.
