Article Synopsis
  • NOTCH3cys variants are common and linked to various small vessel diseases, including early-onset stroke and dementia, but there is no comprehensive staging system to assess their severity.
  • A cohort study created and validated a simple staging system for NOTCH3-SVD by analyzing data from several international cohorts and the UK Biobank, focusing on the impact of these variants on CVD outcomes and cognition.
  • The new system includes 9 disease stages, aiding in understanding the relationship between stages and clinical outcomes like ischemic strokes, cognitive function, and brain damage.

Alcohol use disorder (AUD) is defined as the impaired ability to stop or control alcohol use despite adverse social, occupational, or health consequences and still represents one of the biggest challenges for society regarding health conditions, social consequences, and financial costs, including the high relapse rates after traditional alcohol rehabilitation treatment. Especially, the deficient emotional competence in AUD is said to play a key role in the development of AUD and hinders the interruption of substance compulsion, often leading to a viscous circle of relapse. Although the empirical evidence of a neurophysiological basis of AUD is solid and increases even further, clinical interventions based on neurophysiology are still rare for individuals with AUD.

Background And Objectives: Pathogenic variants in are the main cause of hereditary cerebral small vessel disease (SVD). SVD-associated variants have recently been categorized into high risk (HR), moderate risk (MR), or low risk (LR) for developing early-onset severe SVD. The most severe NOTCH3-associated SVD phenotype is also known as cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL).

For the quantification of insulin activity, United States Pharmacopeia (USP) general chapter <121> continues to require the rabbit blood sugar test. For new insulin or insulin analogue compounds, those quantitative data are expected for stability or comparability studies. At Sanofi, many rabbits were used to fulfil the authority's requirements to obtain quantitative insulin bioactivity data until the in vivo test was replaced.

Article Synopsis
  • Cysteine-altering missense variants in the NOTCH3 protein cause NOTCH3-associated small vessel disease (NOTCH3-SVD), which shows a wide range of severity, including severe conditions like CADASIL and milder cases.
  • The study aimed to enhance risk prediction for NOTCH3-SVD by analyzing differences in NOTCH3cys variant frequencies across various EGFr domains, categorizing them into low, medium, or high-risk classifications.
  • The findings revealed that certain EGFr domains (1-6, 8, 11, and 26) were associated with a significantly higher stroke risk compared to others, indicating the potential for genotype-based risk stratification in clinical settings.

Background: A retrospective study has shown that EGFr (epidermal growth factor-like repeat) group in the gene is an important cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) disease modifier of age at first stroke and white matter hyperintensity (WMH) volume. No study has yet assessed the effect of other known CADASIL modifiers, that is, cardiovascular risk factors and sex, in the context of EGFr group. In this study, we determined the relative disease-modifying effects of EGFr group, sex and cardiovascular risk factor on disease severity in the first genotype-driven, large prospective CADASIL cohort study, using a comprehensive battery of CADASIL clinical outcomes and neuroimaging markers.

Article Synopsis
  • Primate thanatology, the study of how primates respond to death, has seen increased interest but still lacks comprehensive data and quality reports.
  • This research focuses on the northern muriqui, detailing seven specific cases of adult female responses to dead or dying infants observed from 1998 to 2020.
  • Findings indicate adult females carried their deceased young for 1-3 days primarily during dry seasons, emphasizing the importance of long-term studies in documenting such rare behaviors in primates.

The dominant factors in Microbial Influenced Corrosion (MIC) are hard to determine because normally several individual species and their metabolites are involved, and, moreover, different metabolites may cause opposing effects. To address this problem, the effects of individual metabolites from different species should be elucidated when at the same time other metabolites are held constant. In this study, the role is investigated of simulated organic acid metabolites, namely, acetic and L-ascorbic acids, on corrosion of geo-energy pipelines (carbon steel) in a simulated Sulfate Reducing Bacteria (SRB) environment.

Introduction: The role of positron-emission tomography/computed-tomography (PET/CT) in the management of sarcomas and as a prognostic tool has been studied. However, it remains unclear which metric is the most useful. We aimed to investigate if volume-based PET metrics (Tumor volume (TV) and total lesions glycolysis (TLG)) are superior to maximal standardized uptake value (SUVmax) and other metrics in predicting survival of patients with soft tissue and bone sarcomas.

Aims: CADASIL, the most prevalent hereditary cerebral small vessel disease, is caused by cysteine-altering NOTCH3 variants (NOTCH3 ) leading to vascular NOTCH3 protein aggregation. It has recently been shown that variants located in one of NOTCH3 protein epidermal growth-factor like repeat (EGFr) domains 1-6, are associated with a more severe phenotype than variants located in one of the EGFr domains 7-34. The underlying mechanism for this genotype-phenotype correlation is unknown.

Article Synopsis
  • Cysteine altering variants, linked to a rare hereditary small vessel disease, were studied to see if individuals carrying these variants have more brain small vessel disease markers and higher risks of stroke and cognitive issues compared to those without the variants.
  • A study with data from 92,456 participants found that individuals with cysteine altering variants exhibited a significantly higher risk of stroke, particularly after age 65, and had a greater burden of brain lesions in MRI scans.
  • Despite the higher incidence of stroke in the variant carriers, rates of dementia and depression were similar between both groups, suggesting the need for further investigation into the broader impacts of these genetic variants.

Primates are great fruit consumers and disperse intact seeds from most of the plants they consume, but effective seed dispersal depends, amongst other factors, on handling behavior. Likewise, the treatment in gut and mouth may alter seed fate. Overall, frugivore and folivore-frugivore primates are recognized to provide beneficial gut treatment for Neotropical plant species, but this effect might be overlooked at species-specific levels.

Evidence has accumulated that emotion recognition performance varies with menstrual cycle phase. However, according to some empathy models, facial affect recognition constitutes only one component of empathic behavior, besides emotional perspective taking and affective responsiveness. It remains unclear whether menstrual cycle phase and thus estradiol and progesterone levels are also associated with the two other empathy constructs.
