In this study, a novel recombinant amylosucrase from Truepera radiovictrix DSM 17093 was characterized and found to produce α-glucans from sucrose. The enzyme showed maximum total and transglucosylation activities at pH 7.5 and maximum hydrolysis activity at pH 5.5. The optimum temperature for total, transglucosylation, and hydrolysis activities were determined to be 45, 45, and 50 °C, respectively. When the conversion of 100 mM sucrose was catalyzed at 35, 45, and 55 °C for 24 h, TR-ASase produced α-(1,4) glucans with average DPs of 59, 45, and 37, respectively...

BACKGROUND: Antidepressants are a first-line treatment for adults with moderate to severe major depression. However, many people prescribed antidepressants for depression don't respond fully to such medication, and little evidence is available to inform the most appropriate 'next step' treatment for such patients, who may be referred to as having treatment-resistant depression (TRD). National Institute for Health and Care Excellence (NICE) guidance suggests that the 'next step' for those who do not respond to antidepressants may include a change in the dose or type of antidepressant medication, the addition of another medication, or the start of psychotherapy...

Exogenous amylase supplementation can increase starch and fiber digestibility in lactating dairy cows. We evaluated the effect of exogenous amylase supplementation on diets with high starch concentration (32% of dry matter). Twenty-eight Holstein cows (171 ± 80 d in milk, 4 primiparous) received a standard diet for 14 d and then a treatment for 63 d, in a covariate-adjusted randomized block design with repeated measures over time. Treatments were amylase [0.5 g of Ronozyme RumiStar (DSM Nutritional Products, Basel, Switzerland) per kg of total mixed ration dry matter] or control...

OBJECTIVE: Adverse Childhood Experiences (ACEs) have consistently been associated with a range of negative psychological and physical outcomes in adulthood. Despite the strength of this association, no studies to date have investigated psychological processes that might underlie this relationship. The current study evaluated emotion regulation as a potential mediator between ACEs and three outcomes: PTSD symptoms, depression and poor physical health, all of which are frequently co-occurring among women with ACEs...

Accumulating evidence suggests that genetic factors have a role in major depressive disorder (MDD). However, only limited MDD risk loci have been identified so far. Here we perform a meta-analysis (a total of 90,150 MDD cases and 246,603 controls) through combing three genome-wide association studies of MDD, including 23andMe (cases were self-reported with a clinical diagnosis or treatment of depression), CONVERGE (cases were diagnosed using the Composite International Diagnostic Interview) and PGC (cases were diagnosed using direct structured diagnostic interview (by trained interviewers) or clinician-administered DSM-IV checklists)...

Objective: The Difficulties in Emotion Regulation Scale (DERS) is a widely used self-report measure of subjective emotion ability, as defined by a prominent clinically derived model of emotion regulation (Gratz and Roemer, 2004). Although the DERS is often used in treatment and research settings for adults with emotional (i.e., anxiety, mood, obsessive-compulsive, or trauma-related) disorders, its psychometric properties are not well-characterized in this population. Method: We examined the psychometric properties of the DERS and three popular short forms (DERS-16; DERS-18; and DERS-SF) in a large ( N = 427) sample of treatment-seeking adults with one or more DSM-5 emotional disorders...

Aims: The DSM-5 introduced the term "major neurocognitive disorders" (NCDs) to replace the previous term "dementia." However, psychometric and functional definitions of NCDs are missing. We aimed to apply the DSM-5 criteria for diagnosing the transition to NCD to patients with mild cognitive impairment (MCI) and small vessel disease (SVD), and to define clinically significant thresholds for this transition. Methods: The functional and cognitive features of the NCD criteria were evaluated as change from baseline and operationalized according to hierarchically ordered psychometric rules...

Approximately 1.8 million young adults aged 18 to 25 had a Cannabis Use Disorder (CUD) in the past year. Unfortunately, engaging young adults in treatment is very challenging. Creative approaches to treat cannabis disorders such as integrating mobile technology with evidence-based treatments are warranted. In light of these challenges, we developed a text message-delivered version of Peer Network Counseling (PNC-txt), which is a substance use intervention that focuses on peer relations. PNC-txt engages participants in 16 automated, personalized text interactions over 4weeks...

OBJECTIVE: Despite robust interest in the association between inflammation and depression, anti-inflammatory markers have been scarcely investigated as predictors of the future risk of depression. The aim of this study is to determine whether up-regulation of plasma adiponectin, an anti-inflammatory adipokine, precedes and predicts the development of depression in the elderly. METHODS: This prospective cohort study was launched in 2005. Among 1,000 participants who were randomly sampled from community-dwelling individuals 65 years or older, 633 euthymic individuals without prior history of depressive disorders were enrolled for a baseline evaluation and follow-up after 5 years...
