The Same-Sex Marriage Cases and Federal Jurisdiction: On Third-Party Standing and Why the Domestic Relations Exception to Federal Jurisdiction Should Be Overruled

In this paper, we consider two questions. First, we address whether there was proper standing for the Article III courts to decide United States v. Windsor, 570 U.S. 133 S. Ct. 2675, 2696 (2013) and Hollingsworth v. Perry, 133 S. Ct. 2652, 2668 (2013). We conclude that the third-party appellants lacked standing in federal court. Second, we examine whether cases challenging state same-sex marriage bans were and are cases in “law and equity” or instead, barred under the domestic relations exception for the purposes of federal question jurisdiction. We conclude that the domestic relations exception to federal jurisdiction is an archaic, historical remnant that should be overruled by the U.S. Supreme Court, and thus, the Article III federal courts have jurisdiction to hear pure marital status cases despite their domestic nature. We call on the Supreme Court to eliminate the domestic relations exception as to all forms of federal jurisdiction

Stability of Satellite Planes in M31 II: Effects of the Dark Subhalo Population

The planar arrangement of nearly half the satellite galaxies of M31 has been a source of mystery and speculation since it was discovered. With a growing number of other host galaxies showing these satellite galaxy planes, their stability and longevity have become central to the debate on whether the presence of satellite planes are a natural consequence of prevailing cosmological models, or represent a challenge. Given the dependence of their stability on host halo shape, we look into how a galaxy plane's dark matter environment influences its longevity. An increased number of dark matter subhalos results in increased interactions that hasten the deterioration of an already-formed plane of satellite galaxies in spherical dark halos. The role of total dark matter mass fraction held in subhalos in dispersing a plane of galaxies present non trivial effects on plane longevity as well. But any misalignments of plane inclines to major axes of flattened dark matter halos lead to their lifetimes being reduced to < 3 Gyrs. Distributing > 40% of total dark mass in subhalos in the overall dark matter distribution results in a plane of satellite galaxies that is prone to change through the 5 Gyr integration time period.Comment: 11 pages, 9 figures, accepted to MNRAS September 22 201

Controlled sulfur-based engineering confers mouldability to phosphorothioate antisense oligonucleotides

Phosphorothioates (PS) have proven their effectiveness in the area of therapeutic oligonucleotides with applications spanning from cancer treatment to neurodegenerative disorders. Initially, PS substitution was introduced for the antisense oligonucleotides (PS ASOs) because it confers an increased nuclease resistance meanwhile ameliorates cellular uptake and in-vivo bioavailability. Thus, PS oligonucleotides have been elevated to a fundamental asset in the realm of gene silencing therapeutic methodologies. But, despite their wide use, little is known on the possibly different structural changes PS-substitutions may provoke in DNA·RNA hybrids. Additionally, scarce information and significant controversy exists on the role of phosphorothioate chirality in modulating PS properties. Here, through comprehensive computational investigations and experimental measurements, we shed light on the impact of PS chirality in DNA-based antisense oligonucleotides; how the different phosphorothioate diastereomers impact DNA topology, stability and flexibility to ultimately disclose pro-Sp S and pro-Rp S roles at the catalytic core of DNA Exonuclease and Human Ribonuclease H; two major obstacles in ASOs-based therapies. Altogether, our results provide full-atom and mechanistic insights on the structural aberrations PS-substitutions provoke and explain the origin of nuclease resistance PS-linkages confer to DNA·RNA hybrids; crucial information to improve current ASOs-based therapies.© The Author(s) 2023.

Reading related white matter structures in adolescents are influenced more by dysregulation of emotion than behavior

Mood disorders and behavioral are broad psychiatric diagnostic categories that have different symptoms and neurobiological mechanisms, but share some neurocognitive similarities, one of which is an elevated risk for reading deficit. Our aim was to determine the influence of mood versus behavioral dysregulation on reading ability and neural correlates supporting these skills in youth, using diffusion tensor imaging in 11- to 17-year-old children and youths with mood disorders or behavioral disorders and age-matched healthy controls. The three groups differed only in phonological processing and passage comprehension. Youth with mood disorders scored higher on the phonological test but had lower comprehension scores than children with behavioral disorders and controls; control participants scored the highest. Correlations between fractional anisotropy and phonological processing in the left Arcuate Fasciculus showed a significant difference between groups and were strongest in behavioral disorders, intermediate in mood disorders, and lowest in controls. Correlations between these measures in the left Inferior Longitudinal Fasciculus were significantly greater than in controls for mood but not for behavioral disorders. Youth with mood disorders share a deficit in the executive-limbic pathway (Arcuate Fasciculus) with behavioral-disordered youth, suggesting reduced capacity for engaging frontal regions for phonological processing or passage comprehension tasks and increased reliance on the ventral tract (e.g., the Inferior Longitudinal Fasciculus). The low passage comprehension scores in mood disorder may result from engaging the left hemisphere. Neural pathways for reading differ mainly in executive-limbic circuitry. This new insight may aid clinicians in providing appropriate intervention for each disorder

Enhanced brainstem cerebral blood flow accompanies symptoms of anhedonia in young adults

Study: Midbrain serotonergic projections are of crucial theoretical significance for mood disorders. Furthermore, learned helplessness (LH) is associated with enhanced metabolic activity in rodent serotonergic midbrain models. However, little evidence supports serotonergic projections in predicting illness severity. We employed arterial spin labeling (ASL) to measure whole brain cerebral blood flow (CBF) in distressed and healthy individuals varying in anxiety and anhedonia. Methods: 36 distressed (27 females; mean age=22.2, SD=2.1) and 34 healthy (19 females; mean age=21.5, SD=1.8) individuals underwent a resting acquisition. Blood flow was measured using a multiband pseudo continuous ASL sequence. Regional cerebral perfusion data was collected with 25 slices, multiband factor=5, 4mm slick thickness, FA=90, 64x64 resolution, FOV=192x912, TR/TE=3.5s/19ms, labeling time=1.5s and postlabeling delay=1.7s. Anhedonia was measured using the Mood and Anxiety Symptom Questionnaire Anhedonic Depression Scale (MASQ-ADS), with the Snaith–Hamilton Pleasure Scale (SHAPS) as a secondary measure. Anxiety was measured using the MASQ General Distress Anxious Symptoms Scale. Anhedonia, anxiety and group were included in the regression model. Results: Anhedonia (MASQ-ADS) was associated with increased CBF in the midbrain (T=5.24, p_FWE=0.033), proximal to putative locations of the dorsal/median raphe nuclei (-12, -34, -26). Similar, although weaker, findings were observed with the SHAPS. Conclusion: Anhedonia is associated with altered CBF in the midbrain in a young adult population showing heterogeneous symptoms of distress. Significance: ASL may provide a particularly promising tool to examine enhanced local perfusion, potentially reflecting underlying midbrain serotonergic activity, which is predicted on the basis of LH studies in rodents but has thus far been difficult to investigate in humans
