2.1. Preparation of GEO. A crude ginger extract was prepared as previously described by extracting ground ginger rhizome (2500g) with CH 2 Cl 2 (dichloromethane) at 25°C for 36 h (6.4% yield) [6,12].After filtration, washing and work up, 40 g of the resultant extract ("crude ginger extract') were applied to a silica gel column and sequentially eluted with solvents of increasing …
Materials and Methods—a randomized trial was carried out on 20 male elite runners who had previously undertaken nutritional and gut training, and who consumed different CHO dosages according to experimental (EXP—120 g/h), control (CON—90 g/h) and low CHO intake (LOW—60 g/h) groups during a ~4000 m cumulative slope mountain marathon.
Psychedelic compounds, such as psilocybin, have beneficial actions in several psychiatric diseases. They also produce strong alterations of consciousness, which may be a barrier to their widespread use. We found that psilocybin has fast-acting antidepressant-like properties in mice. Using multiple assays of hedonic behavior and an antagonist of …

Background: Evidence consistently shows that almond consumption beneficially affects lipids and lipoproteins. Almonds, however, have not been evaluated in a controlled-feeding setting using a diet design with only a single, calorie-matched food substitution to assess their specific effects on cardiometabolic risk factors.
Objective The coronavirus disease 2019 (COVID-19) has spread worldwide since December 2019. Neurologic symptoms have been reported as part of the clinical spectrum of the disease. We aimed to determine whether neurologic manifestations are common in hospitalized patients with COVID-19 and to describe their main characteristics. Methods We systematically …
In practice, equation 1 may not provide sufficient gradient for Gto learn well. Early in learning, when Gis poor, Dcan reject samples with high confidence because they are clearly different from the training data. In this case, log(1 D(G(z))) saturates. Rather than training Gto minimize log(1 D(G(z))) we can train Gto maximize logD(G(z)).

Background Chest CT is used in the diagnosis of coronavirus disease 2019 (COVID-19) and is an important complement to reverse-transcription polymerase chain reaction (RT-PCR) tests. Purpose To investigate the diagnostic value and consistency of chest CT as compared with RT-PCR assay in COVID-19. Materials and Methods This study included 1014 …
Sudden, loud noises are one of the most common triggers for fearful behaviors in dogs, and many companion dogs suffer from noise sensitivity. Existing research focuses on dramatic infrequent sounds (e.g., thunderstorms, fireworks). Anecdotally, and based on reports of undesirable behaviors in response to noises in the home, many common noises may also be …
