This study was performed to investigate the influence of Lepidium perfoliatum seed gum (LPSG) and Alyssum homolocarpum seed gum (AHSG) on functional properties of wheat starch. Various concentrations of gums (0.25%, 0.5%, 0.75%, and 1% dry starch weight basis) were added to wheat starch, and their influences on water absorption, pasting properties, gel strength, freeze-thaw stability and color parameters were investigated. ENOblock research buy The results showed that both gums improved water absorption, freeze-thaw stability, pasting parameters, gel hardness, gumminess, and chewiness whereas springiness was not affected and cohesiveness was decreased by the incorporation of gums and LPSG more effective than AHSG. Color parameters were also affected by the concentration of gums. The L value decreased whereas a value and b value increased in the presence of both gums. However, the changes were more obvious in samples containing LPSG. PRACTICAL APPLICATION Starch is one of the most important carbohydrate materials in the food industry. However, native starch has shortcomings, such as sensitivity to shear or syneresis that limit its applications in food processing. Incorporation of hydrocolloids is an effective strategy to improve functional properties of starch. LPSG and AHSG are two novel sources of hydrocolloids which can be used to modify the properties of starch in food products.The purpose of this study was to examine the applicability of the use of samples in dried blood spot (DBS) for the definitive diagnosis of Fabry disease (FD) in males and females and to compare the diagnostic role of α-galactosidase A activity (α-Gal A), levels of lyso-Gb3 and sequencing of the GLA gene in screening patients with suspected FD. Measurement of α-Gal A activity in suspected FD patients in DBS was made followed by lyso-Gb3 determination and GLA gene sequencing. Of the 2381 subjects analyzed, FD was confirmed in 24 patients. Thirteen different variants were considered like pathogenic, five of which had not been previously described (c.143A > G; c.455A > C; c.487G > T; c.554delA; c.1045_1046insA). None of the patients with normal enzyme activity had FD confirmation. The DBS measurement of α-Gal A was more sensitive than lyso-Gb3 levels in both men and women. Definitive diagnosis of FD from a single DBS is possible, allowing samples to be easily sent from anywhere to the reference laboratory.
COVID-19 is associated with an exacerbated inflammatory response that can result in fatal outcomes. Systemic inflammation is also a main characteristic of periodontitis. Therefore, we investigated the association of periodontitis with COVID-19 complications.

A case-control study was performed using the national electronic health records of the State of Qatar between February and July 2020. Cases were defined as patients who suffered COVID-19 complications (death, ICU admissions or assisted ventilation), and controls were COVID-19 patients discharged without major complications. Periodontal conditions were assessed using dental radiographs from the same database. Associations between periodontitis and COVID 19 complications were analysed using logistic regression models adjusted for demographic, medical and behaviour factors.

In total, 568 patients were included. After adjusting for potential confounders, periodontitis was associated with COVID-19 complication including death (OR=8.81, 95% CI 1.00-77.7), ICU admission (OR=3.54, 95% CI 1.39-9.05) and need for assisted ventilation (OR=4.57, 95% CI 1.19-17.4). Similarly, blood levels of white blood cells, D-dimer and C Reactive Protein were significantly higher in COVID-19 patients with periodontitis.

Periodontitis was associated with higher risk of ICU admission, need for assisted ventilation and death of COVID-19 patients, and with increased blood levels of biomarkers linked to worse disease outcomes.

Live hands-on demonstration of dental procedures is a central format in undergraduate dental teaching. It captures the immediacy of the clinical situation and allows for direct communication between instructor and students, but it also requires an experienced instructor who is able to handle both the performed treatment and its visualization alongside the actual teaching. The aim of the present work is to compare the hands-on demonstration of a class IV composite restoration to a teaching format where the instructor guided the students through a prerecorded procedural video of the same treatment.

The effect of both interventions on the students' self-perceived learning outcomes was analyzed by questionnaires (response rate 100%) in a randomized controlled double-blind (participants, outcome assessor) parallel group design (September 10 to October 3, 2019). In-class discussions were explored qualitatively by thematic analysis.

Both teaching formats increased the students' self-reported motivation, self-efficacy, and patient-centeredness in a similar way, with no significant differences between interventions. During in-class discussions, both the instructor and the students were more active in the video group. In contrast to the hands-on group, discussions in the video group also involved patient-related topics, such as aesthetics and general health. The video-supported teaching format considerably reduced the amount of time spent on optimizing the visualization of the performed treatment.

Video-supported instructor-guided demonstrations may represent a promising teaching format as an alternative to live hands-on demonstrations of dental procedures in undergraduate dental education.

The objectives were to determine the performance of saliva in comparison with NPS for detecting SARS-CoV-2 and to compare the optimized home brew reverse-transcription polymerase chain reaction (RT-PCR) with a commercial RT-PCR. Paired NPS and saliva specimens were prospectively collected and tested by RT-PCR from patients presenting at an emergency room with signs and symptoms compatible with coronavirus disease-2019. A total of 348 samples from 174 patients were tested by RT-PCR assays. Among 174 patients with symptoms, 63 (36%) were SARS-CoV-2 positive in NPS using the optimized home-brew PCR. Of these 63 patients, 61 (98%) were also positive in saliva. An additional positive SARS-CoV-2 saliva was detected in a patient with pneumonia. Kappa Cohen's coefficient agreement between NPS and saliva was 0.96 (95% confidence interval [CI], 0.
