The HypF protein is involved in the maturation and regulation of hydrogenases. The N-terminal domain of HypF (HypF-N) has served as a key model system to study the pathways of protein amyloid formation and the nature of the toxicity of pre-fibrilar protein oligomers. This domain can aggregate into two forms of oligomers having significantly different toxic effects when added to neuronal cultures. Here, NMR assignments of HypF-N backbone resonances are presented in its native state and under the conditions favouring the formation of toxic and non-toxic oligomers. The analyses of chemical shifts provide insights into the protein conformational state and the possible pathways leading to the formation of different types of oligomers.

In Arabidopsis thaliana, micro-RNA regulation is primarily controlled by DCL1, an RNase III enzyme, and its associated proteins. DCL1, together with DRB2, governs a specific group of miRNAs that induce the inhibition of target mRNA translation. DRB2 is a multi-domain protein containing two N-terminal dsRNA binding domains (dsRBD) separated by a linker, followed by an unstructured C-terminal tail.

The Alkbh7 protein, a member of the Alkylation B (AlkB) family of dioxygenases, plays a crucial role in epigenetic regulation of cellular metabolism. This paper focuses on the NMR backbone resonance assignment of Alkbh7, a fundamental step in understanding its three-dimensional structure and dynamic behavior at the atomic level. Herein, we report the backbone H, N, C chemical shift assignment of the full-length human Alkbh7.

Cognitive and neural mechanisms underlying bipolar disorder (BD) and its treatment are still poorly understood. Here we examined the role of adaptations in risk-taking using a reward-guided decision-making task. We recruited volunteers with high (n = 40) scores on the Mood Disorder Questionnaire, MDQ, suspected of high risk for bipolar disorder and those with low-risk scores (n = 37).

: Non-alcoholic fatty liver disease (NAFLD) has become a growing public health problem worldwide, and dietary interventions have important potential in the prevention and treatment of NAFLD. Moreover, previous animal studies have shown that flaxseed has a good improvement effect in animal NAFLD models. : Assess whether flaxseed powder could improve the liver lipid content in patients with NAFLD.

Background: We synthesised the current evidence in coverage and quality of delivery care, change in neonatal mortality (NMR), and causes of neonatal death in the private sector deliveries in the Indian state of Bihar from 2011 to 2021.
Methods: Women aged 15-49 years with livebirths were interviewed in three household surveys involving state-representative samples in 2011, 2016 and 2020-2021 designed to document the coverage of maternal and newborn health services and change in NMR over time. Verbal autopsy interviews were used to assign the cause of neonatal death.
