Perceived ethnic discrimination (PED) is thought to underlie increased prevalence of depressed mood in ethnic minorities. Metabolism activator Depression is associated with increased sympathetic and decreased parasympathetic activity. We investigated a biopsychosocial model linking PED, disrupted sympathovagal balance and depressed mood. Baseline data of HELIUS, a cohort study on health among a multi-ethnic population, was used. Heart rate variability (HRV), baroreflex sensitivity (BRS), PED (evaluated with the Everyday Discrimination Scale) and presence of depressed mood (evaluated with the Patient Health Questionnaire-9) were assessed. Associations of PED, HRV/BRS and depressed mood were analyzed with linear and logistic regression analyses. Mediation of the association of PED and depressed mood by HRV/BRS was assessed in a potential outcomes model and four steps mediation analysis. Of 9492 included participants, 14.7% fulfilled criteria for depressed mood. Higher PED was associated with depressed mood (P less then .001). Lower autonomic regulation indexes were associated with depressed mood (deltaR2 = 0.4-1.1%, P less then .001) and at most weakly with PED (deltaR2 = 0.2-0.3%, P less then .001). A very modest mediating effect by HRV/BRS in the association between PED and depressed mood was attenuated after adjustment for socioeconomic status. To conclude, we found no support for the hypothesis that autonomic regulation relevantly mediates the association between PED and depression.
Knowledge about progressive Multiple Sclerosis (MS) is mainly based on Caucasian studies. In our North-African context, MS exhibits particular characteristics that are mainly related to a more severe phenotype. Given the limited data available, there is an imminent need to characterize progressive MS in our latitudes.
To describe the specificities of progressive MS and identify the inherent clinical predictors of disability accrual with a Tunisian cohort.
A retrospective, hospital-based study was conducted in the department of neurology of Razi hospital. Patients, who had been diagnosed with MS, were divided into relapsing MS (RRMS), secondary progressive MS (SPMS) and primary progressive MS (PPMS). Epidemiological, clinical and paraclinical data were compared among the three groups.
Of the 504 patients, a progressive MS was described among 115 patients. This percentage of (22.8%) is divided into 13.9% SPMS and 8.9% PPMS. During the first clinical attack, motor symptoms have revealed to be predominant during PPMS (91.1%). link2 For SPMS onset, the median time was 10 years, and was significantly delayed for patients with visual onset or full recovery from the first relapse. Patients with progressive MS exhibited a more rapid disability accumulation.
Compared to Caucasians, Tunisians exhibited a faster rate of conversion to SPMS. According to our natural progressive MS history, early clinical features are predictors of MS disability accrual.

In accordance with expert guidance, patients have typically continued to receive treatment with subcutaneous interferon beta-1a (sc IFN β-1a) for relapsing multiple sclerosis (MS) during the COVID-19 pandemic.
We provide a summary of outcomes among sc IFN β-1a-treated patients with adverse events related to confirmed or suspected COVID-19, as reported to the Merck Global Patient Safety Database (as of 2 February 2021). Serious COVID-19-related adverse events (as classified by the reporting clinician) included those leading to hospitalization, admission to intensive care, or death. Outcomes were classified per usual pharmacovigilance practice.
The evaluable cohort comprised 603 patients of median age 43 (range, 13-84) years and 75.1% were female. COVID-19 was experienced at a median of 33.0 (range, 0-321.8) months after start of treatment with sc IFN β-1a. A total of 136 (22.6%) patients experienced serious COVID-19 events, including 59 hospitalizations (4 patients admitted to intensive care) and 5 deaths (fatality rate, 0.8%). Regarding non-fatal outcomes, 47.8% of patients (289/603) with COVID-19 adverse events were recovered or recovering at time of analysis; similar findings were apparent for the serious and hospitalized cohorts.
Findings of this analysis from the Merck Global Patient Safety Database suggest that, compared with available statistics for the general population and those with MS, patients receiving sc IFN β-1a for treatment of relapsing MS have relatively low rates of serious disease and/or severe outcomes with COVID-19.

Cognitive impairment is common in multiple sclerosis at all stages of the condition. The natural history of cognition in multiple sclerosis has been considered to be deterioration of cognitive functioning over time. The development of the Brief International Cognitive Assessment for Multiple Sclerosis(BICAMS) has allowed standardization of a screening tool for cognitive impairment which can be easily performed in the neurology clinic. Cross-sectional and validation studies using BICAMS have been widely reported, however minimal longitudinal assessment of cognition using BICAMS has taken place to date.
The objective of this study was to evaluate the prevalence of cognitive impairment at a five-year interval in participants of an original BICAMS validation study. We will also evaluate change of the BICAMS subtests over time.
Participants of the original BICAMS validation study were invited to participate in the study. Demographic and clinical details were collected. BICAMS subtests, anxiety, depression an effects, although familiarity with the testing protocol may exert an influence.Trimethylamine (TMA) commonly exists in daily life and is harmful to human health, therefore the convenient and sensitive monitoring of TMA is highly desired. In this study, we developed a method to fabricate a high-performance TMA sensor by chemically conjugating olfactory receptor-derived peptides (ORPs) to single-walled carbon nanotubes (SWCNTs) on interdigital electrodes. First, the SWCNTs were modified with thioester by Steglich esterification reaction. Next, the ORPs with a cysteine residue at the N-terminus were connected to the thioester by native chemical ligation and modified to the surface of the SWCNTs. The chemical connection method enabled more effective loading of ORPs to the SWCNTs compared to the previously reported physical connection method. Using this approach, the ORPs-SWCNTs sensor for gaseous TMA was fabricated and enabled detection of TMA with a concentration as low as 0.01 parts per trillion, which was three orders of magnitude lower than the reported lowest detection limit up to date. Furthermore, we tested the performance of the ORP-sensor with vaporized TMA and TMA generated from various spoiled food, and the sensor exhibited excellent sensitivity, selectivity, and stability for TMA detection. link3 The results demonstrated the effectiveness of the proposed chemical connection method for the fabrication of ORP-sensor and the great potential of using these sensors for applications in environmental safety, food quality evaluation, and healthcare.To understand the physio-pathological state of patients suffering from chronic diseases, scientists and clinicians need sensors to track chemical signals in real-time. However, the lack of stable, safe, and scalable biochemical sensing platforms capable of continuous operation in liquid environments imposes significant challenges in the timely diagnosis, intervention, and treatment of chronic conditions. This work reports a novel strategy for fabricating waterproof and flexible biochemical sensors with active electronic components, which feature a submicron encapsulation layer derived from monocrystalline Si nanomembranes with a high structural integrity due to the high formation temperature (>1000 °C). The ultrathin, yet dense and low-defect encapsulation enables continuous operation of field-effect transistors in biofluids for chemical sensing. The excellent stability in liquid environment and pH sensing performance of such transistors suggest their great potential as the foundation of waterproof and scalable biochemical sensors with active functionalities in the future. The understandings, knowledge base, and demonstrations for pH sensing reported here set the stage for the next generation long-term biosensing with a broad applicability in biomedical research, food science, and advanced healthcare.High intensity ultrasound (HIU) is a technique with the potential to improve meat quality, however, more research is needed on its application within the chain of cold storage and freezing. This study evaluates the effect of HIU (40 kHz, 9.6 W/cm2, 20 and 40 min) and post-mortem development on the yield and physicochemical quality of rabbit meat in samples treated with HIU pre- and post-storage in a freezer (120 h at -20 °C). Twenty rabbit carcasses were vacuum packed 12 h post-mortem, placed in a fridge at 4 °C for 24 h, and divided in two groups (HIU application before or after freezing), before assigning the treatments. The results show that HIU before freezing produced intense and bright orange-yellow colours, whereas its application after freezing resulted in pale red tones. HIU application accelerates rigor mortis resolution when it is applied before freezing and causes a significant decrease in pH immediately following the HIU treatment. Post-freezing application of HIU is not recommended because it considerably increased weight loss and toughening of the meat when long exposure times were used (40 min). In contrast, a short treatment duration with HIU mitigated the effects of freezing and produced significant increases in water-holding capacity (WHC) after cold storage. The yield (weight loss) of the rabbit meat was not affected when HIU was applied pre-freezing. The application of HIU pre-freezing constitutes a promising technology because it increased the tenderness and the WHC of rabbit meat. However, more research is needed to improve the appearance before scaling up to industrial levels.Optimization of microalgal growth and high-value metabolite production are key steps in microalgal mass culture for the algae industry. An emerging technology is the use of phytohormones, like indole-3-acetic acid (IAA), to promote microalgal growth. This requires an understanding of the biosynthesis of IAA in microalgae-bacteria associations and its function in regulating algal physiology and metabolite production. We review the current advances in understanding of microalgal and bacterial auxin biosynthesis and their implications for algal biotechnology.Micro-fabrication and nano-fabrication provide useful approaches to address fundamental biological questions by mimicking the physiological microenvironment in which cells carry out their functions. In particular, 2D patterns and 3D scaffolds obtained via lithography, direct laser writing, and other techniques allow for shaping hydrogels, synthetic polymers and biologically derived materials to create structures for (single) cell culture. Applications of micro-scaffolds mimicking cell niches include stem cell self-renewal, differentiation, and lineage specification. This review moves from technological aspects of scaffold microfabrication for cell biological applications to a broad overview of advances in (stem) cell research achievements for embryonic, induced pluripotent, mesenchymal, and neural stem cells are treated in detail, while a particular section is dedicated to micro-scaffolds used to study single cells in basic cell biology.
