The South Asian Family Approaches to Disease (SAFAD) Study: Study Rationale, Design, and Progress
Creators: name: Desai, Shreya
Publisher: name: Stanford Digital Repository
Year: 2022
Subjects: subject: Breast--Cancer
subject: South Asians
subject: Caregivers

description: INTRODUCTION: An increasing number of South Asians (people with heritage from India, Pakistan, Nepal, Bhutan, Sri Lanka, Maldives, and Bangladesh) are managing breast cancer due to rising prevalence and decreasing mortality of breast cancer in this population both globally and in the United States. The South Asian Family Approaches to Disease (SAFAD) study aims to better understand the unmet needs of South Asian breast cancer survivors and their informal caregivers and to create a support program for South Asians managing breast cancer.
METHODS: SAFAD is an ongoing study that is led in collaboration with a community advisory board. Health care providers and South Asian breast cancer survivors and their caregivers are recruited through two strategies: a community outreach approach, and a point of care approach. Survivors and caregivers are asked to complete a survey and a semi-structured interview. Providers are asked to complete a semi-structured interview. Interviews are recorded, transcribed, and analyzed using thematic coding. Quantitative data will be analyzed and compared via t-tests and chi-squares for continuous and categorical data, respectively.
RESULTS: The community outreach recruitment approach has yielded three providers but no patients or caregivers. The point of care recruitment approach has yielded one survivor-caregiver dyad and nine survivors. Data has been collected from the dyad and two providers. The survivor has a greater fear of cancer recurrence and greater feelings of isolation compared to their caregiver. The survivor and caregiver both stated that caregiving would be very different in their country of origin, and were comfortable with and could communicate well with their care team. The providers shared observations made when treating South Asian patients, such as their reluctance to discuss sexual dysfunction and to participate in cancer screening practices. 
DISCUSSION: The SAFAD study’s recruitment challenges may stem from three barriers: stem changes in methods for accrual imposed by the COVID 19 pandemic, challenges inherent in conducting dyadic research, and cultural barriers to participation in quality of life research. We plan to continue to utilize both recruitment approaches with a greater focus on the point of care approach.
Are the Lichens Likin’ Salt?: Salinity Tolerance and Resilience of Littoral Lichen Species

description: A limited number of lichen species live on seaside rocks, and little has been studied for these species on the California coast. The salt tolerance of these organisms is interesting – it is unclear whether they have adapted to survive with salt exposure, or if some species depend upon it. Three species of littoral lichens, including Caloplaca coralloides, were collected along the rocky intertidal zone of Monterey Bay and subjected to treatments of varying salinity levels. Photosynthetic activity was assessed based on the Electron Transport Rate (ETR) measured by a miniature Pulse-Amplified Modulated . No significant effect of treatment type was found for any of the species, but there was an effect of the number of days since start of treatment, and no interaction was found between these variables. Based on the results of this preliminary experiment, I propose a follow-up experiment involving the investigation of another possible factor influencing littoral lichen distribution: inundation time. My preliminary work serves to inform how lichens fare in laboratory settings, and how and my persisting inquiries will serve to improve our understanding of their physiology, as well as their role in ecosystem functioning.
Earliest Stages of Protocluster Formation: Substructure and Kinematics of Starless Cores in Orion

description: We study the structure and kinematics of nine 0.1 pc-scale cores in Orion with the IRAM 30-m telescope and at higher resolution eight of the cores with CARMA, using CS(2-1) as the main tracer. The single-dish moment zero maps of the starless cores show single structures with central column densities ranging from 7 to 42 times 10^23 cm^-2 and LTE masses from 20 solar masses to 154 solar masses. However, at the higher CARMA resolution (5 arcsec), all of the cores except one fragment into 3 - 5 components. The number of fragments is small compared to that found in some turbulent fragmentation models, although inclusion of magnetic fields may reduce the predicted fragment number and improve the model agreement. This result demonstrates that fragmentation from parsec-scale molecular clouds to sub-parsec cores continues to take place inside the starless cores. The starless cores and their fragments are embedded in larger filamentary structures, which likely played a role in the core formation and fragmentation. Most cores show clear velocity gradients, with magnitudes ranging from 1.7 to 14.3 km/s/pc. We modeled one of them in detail, and found that its spectra are best explained by a converging flow along a filament toward the core center; the gradients in other cores may be modeled similarly. We infer a mass inflow rate of ~ 2 x 10^{-3} Msolar/yr, which is in principle high enough to overcome radiation pressure and allow for massive star formation. However, the core contains multiple fragments, and it is unclear whether the rapid inflow would feed the growth of primarily a single massive star or a cluster of lower mass objects. We conclude that fast, supersonic converging flow along filaments play an important role in massive star and cluster formation.

The depletion of fucoids on a rocky intertidal shore and its effect on molluscs
Creators: name: Buabbas, Hana
Publisher: name: Stanford Digital Repository
Year: 2022
Subjects: subject: Marine algae
subject: Brown macroalgae
subject: Hewatt transect
subject: Fucoids

description: Fucoids make up a group of brown algae that serve as ecosystem engineers on rocky intertidal shores. They form habitats and modify their environment, often serving as facilitators to other surrounding species. Fucoids have been observed to decline on the Hewatt transect at Stanford University’s Hopkins Marine Station, Pacific Grove, California, consistent with similar observation around the world. Here, we quantify and demonstrate the decline of mean fucoid abundance across quadrats that were once dominated by these brown algae. We also hypothesize that the depletion of fucoid abundance has led to the decrease in mollusc abundance, due to the facilitation relationship between fucoids and molluscs. The abundance of Limpets, Littorina, Tegula, and Chitons were examined in 1933 and compared to present day (2020, 2021). Varying results were found for each of the four selected groups. A correlation between the decline of fucoids and the decline of Limpets was observed. With fucoids known to be decreasing in abundance in several rocky shores around the world, such a study is necessary 25 to investigate and understand the effect of fucoid depletion on their surrounding marine ecosystem.
Heuristics Miners for Streaming Event Data

description: More and more business activities are performed using information systems. These systems produce such huge amounts of event data that existing systems are unable to store and process them. Moreover, few processes are in steady-state and due to changing circumstances processes evolve and systems need to adapt continuously. Since conventional process discovery algorithms have been defined for batch processing, it is difficult to apply them in such evolving environments. Existing algorithms cannot cope with streaming event data and tend to generate unreliable and obsolete results. In this paper, we discuss the peculiarities of dealing with streaming event data in the context of process mining. Subsequently, we present a general framework for defining process mining algorithms in settings where it is impossible to store all events over an extended period or where processes evolve while being analyzed. We show how the Heuristics Miner, one of the most effective process discovery algorithms for practical applications, can be modified using this framework. Different stream-aware versions of the Heuristics Miner are defined and implemented in ProM. Moreover, experimental results on artificial and real logs are reported.

description: Variations in the propagation of globally-propagating disturbances (commonly called "EIT waves") through the low solar corona offer a unique opportunity to probe the plasma parameters of the solar atmosphere. Here, high-cadence observations of two "EIT wave" events taken using the Atmospheric Imaging Assembly (AIA) instrument onboard the Solar Dynamics Observatory (SDO) are combined with spectroscopic measurements from the Extreme ultraviolet Imaging Spectrometer (EIS) onboard the Hinode spacecraft and used to examine the variability of the quiet coronal magnetic-field strength. The combination of pulse kinematics from SDO/AIA and plasma density from Hinode/EIS is used to show that the magnetic-field strength is in the range ~2-6 G in the quiet corona. The magnetic-field estimates are then used to determine the height of the pulse, allowing a direct comparison with theoretical values obtained from magnetic-field measurements from the Helioseismic and Magnetic Imager (HMI) onboard SDO using PFSS and local-domain extrapolations. While local-scale extrapolations predict heights inconsistent with prior measurements, the agreement between observations and the PFSS model indicates that "EIT waves" are a global phenomenon influenced by global-scale magnetic field.

description: Cuprate materials hosting high-temperature superconductivity (HTS) also exhibit various forms of charge and/or spin ordering whose significance is not fully understood. To date, static charge-density waves (CDWs) have been detected by diffraction probes only at special doping or in an applied external field. However, dynamic CDWs may also be present more broadly and their detection, characterization and relationship with HTS remain open problems. Here, we present a new method, based on ultrafast spectroscopy, to detect the presence and measure the lifetimes of CDW fluctuations in cuprates. In an underdoped La1.9Sr0.1CuO4 film (Tc = 26 K), we observe collective excitations of CDW that persist up to 100 K. This dynamic CDW fluctuates with a characteristic lifetime of 2 ps at T = 5 K which decreases to 0.5 ps at T = 100 K. In contrast, in an optimally doped La1.84Sr0.16CuO4 film (Tc = 38.5 K), we detect no signatures of fluctuating CDWs at any temperature, favoring the competition scenario. This work forges a path for studying fluctuating order parameters in various superconductors and other materials.

description: Stalin’s collectivization policies created a famine that killed around 1.5 million people in Soviet Kazakhstan from 1932 to 1933. However, the Kazakhstani state remains reluctant to incorporate the famine into official historical narratives and marginalizes public discourse about this period of history. This paper analyzes the evolution of official rhetoric about the 1932-33 famine from 1991 to today as a lens through which to understand elite-level political concerns behind national identity building in Kazakhstan. I find that an instrumental relationship to history and political expediency governs debates about the famine in Kazakhstan, including the desire to create a civic “Kazakhstani” national identity and concerns about Russia’s stake in Kazakhstan’s memory politics.

description: We study the Susceptible-Infected-Recovered model in complex networks, considering that not all individuals in the population interact in the same way between them. This heterogeneity between contacts is modeled by a continuous disorder. In our model the disorder represents the contact time or the closeness between individuals. We find that the duration time of an epidemic has a crossover with the system size, from a power law regime to a logarithmic regime depending on the transmissibility related to the strength of the disorder. Using percolation theory, we find that the duration of the epidemic scales as the average length of the branches of the infection. Our theoretical findings, supported by simulations, explains the crossover between the two regimes.
The Effects of Sample Size on Significance Testing

description: There are two ways in which a researcher might make incorrect conclusions based on an empirical study's statistical test: false negatives and false positives. Basic statistics highlight the dangers of small samples on false negatives, which is vastly known. Further, statistical significance tests produce a p-value associated with false positives. Thus, while sample size is related to the probability of a false-negative conclusion, it should be unrelated to the probability of a false-positive conclusion. Despite the logic underlying statistical testing, there are rising concerns about the increased chances of producing a false-positive error as the sample size increases. Since scientists have yet to test this relation in depth, this paper leverages data from five independent studies testing five different effects (i.e., 25 samples of ~1500 participants) to examine the effects of sample size on false positives. This paper systematically tests an implausible hypothesis — whether random assignment into experimental and control conditions can predict a participant's demographics — using simulated samples of 50 to 5000. Initial analyses found that large samples were more likely to yield false-positive results than small samples. Subsequent analyses suggest that weak effects of differential attrition, which may be expected in any experiment, may only be detectable in large sample studies. Therefore, large-sampled studies may find experimental effects that are artifacts caused by differential attrition.

description: Recent studies have claimed the existence of very massive stars (VMS) up to 300 solar masses in the local Universe. As this finding may represent a paradigm shift for the canonical stellar upper-mass limit of 150 Msun, it is timely to discuss the status of the data, as well as the far-reaching implications of such objects. We held a Joint Discussion at the General Assembly in Beijing to discuss (i) the determination of the current masses of the most massive stars, (ii) the formation of VMS, (iii) their mass loss, and (iv) their evolution and final fate. The prime aim was to reach broad consensus between observers and theorists on how to identify and quantify the dominant physical processes.

description: The high-Tc alkali doped iron selenide superconductors KxFe{2-y}Se2 have been recently shown to be intrinsically phase separated into Fe vacancy ordered block antiferromagnetic regions and superconducting regions at low temperatures. In this work, we use a microscopic five orbital Hubbard model to obtain the electronic low-energy states near the interfaces between block antiferromagnets and superconductors. It is found that abundant low-energy in-gap bound states exist near such interfaces irrespective of whether the superconductor has d- or s-wave pairing symmetry. By contrast, it is shown how nonmagnetic scattering planes can provide a natural means to distinguish between these two leading pairing instabilities of the KxFe{2-y}Se2 materials.

description: The droplet crystal phase of a symmetric binary mixture of Rydberg-blockaded dipolar Bose gases is studied by computer simulation. At high temperature each droplet comprises on average equal numbers of particles of either component, but the two components demix below the supersolid transition temperature, i.e., droplets mostly consist of particles of one component. Droplets consisting of the same component will also favor clustering. Demixing is driven by quantum tunnelling of particles across droplets over the system, and does not take place in a non-superfluid crystal. This effect should be easily detectable in a cold gas experiment.

description: In the two Higgs doublet model, there is the possibility that the vacuum where the universe resides in is metastable. We present the tree-level bounds on the scalar potential parameters which have to be obeyed to prevent that situation. Analytical expressions for those bounds are shown for the most used potential, that with a softly broken $Z_2$ symmetry. The impact of those bounds on the model's phenomenology is discussed in detail, as well as the importance of the current Large Hadron Collider results in determining whether the vacuum we live in is or is not stable. We demonstrate how the vacuum stability bounds can be obtained for the most generic CP-conserving potential, and provide a simple method to implement them.

description: We report wind measurements within Martian dust devils observed in plan view from the High Resolution Imaging Science Experiment (HiRISE) orbiting Mars. The central color swath of the HiRISE instrument has three separate charge-coupled devices (CCDs) and color filters that observe the surface in rapid cadence. Active features, such as dust devils, appear in motion when observed by this region of the instrument. Our image animations reveal clear circulatory motion within dust devils that is separate from their translational motion across the Martian surface. Both manual and automated tracking of dust devil clouds reveal tangential winds that approach 20-30 m/s in some cases. These winds are sufficient to induce a ~1% decrease in atmospheric pressure within the dust devil core relative to ambient, facilitating dust lifting by reducing the threshold wind speed for particle elevation. Finally, radial velocity profiles constructed from our automated measurements test the Rankine vortex model for dust devil structure. Our profiles successfully reveal the solid body rotation component in the interior, but fail to conclusively illuminate the profile in the outer regions of the vortex. One profile provides evidence for a velocity decrease as a function of r^-1/2, instead of r^-1, suggestive of surface friction effects. However, other profiles do not support this observation, or do not contain enough measurements to produce meaningful insights.

description: On September 3rd 2013, President Serzh Sargsyan announced that Armenia would abandon its proposed Association Agreement with the European Union after years of negotiations. In place of this agreement, Armenia would pursue full membership in the Russian-led Eurasian Economic Union (EAEU). Although this abrupt decision came as a surprise to Armenian political actors and many western observers, this development was the product of years of political maneuvering by Moscow towards Armenia as part of the creation of an alternative model of regional integration within the former Soviet Union. Considering that the European Union and Russia held relative parity with one another as trading partners of Armenia and both Brussels and Moscow held close diplomatic ties with Yerevan this begs the question: what specifically allowed Russia to pry Armenia away from its path of European Integration and secure Yerevan’s membership in the EAEU? In exploring Sargsyan’s decision, this paper will investigate the elements differentiating Russia and Europe’s trading relationship with Armenia, differences between Brussels’ and Moscow’s ability to act as an energy provider to Armenia, and Moscow’s role as a guarantor of security to Yerevan.

description: We exploit exact inequalities that refer to the entropy of a distribution to derive a simple variational principle at finite temperature for trial density matrices of Gutzwiller and Jastrow type. We use the result to extend at finite temperature the Gutzwiller approximation, which we apply to study a two-orbital model that we believe captures some essential features of V$_2$O$_3$. We indeed find that the phase diagram of the model bears many similarities to that of real vanadium sesquioxide. In addition, we show that in a Bethe lattice, where the finite temperature Gutzwiller approximation provides a rigorous upper bound of the actual free energy, the results compare well with the exact phase diagram obtained by the dynamical mean field theory.

description: Semiconductor innovation drives improvements to technologies that are critical to modern society.
The country that successfully accelerates semiconductor innovation is positioned to lead future
semiconductor-driven industries and benefit from the resulting economic growth. It is our view
that a next generation infrastructure is necessary to accelerate and enhance semiconductor innovation
in the U.S. In this paper, we propose such an advanced infrastructure composed of a national
network of facilities with enhancements in technology and business models. These enhancements
enable application-driven and challenge-based research and development, and ensure that facilities
are accessible and sustainable. The main tenets are: a challenge-driven operational model, a
next-generation infrastructure to serve that operational model, technology innovations needed for
advanced facilities to speed up learning cycles, and innovative cost-effective business models for
sustainability. Ultimately, the expected outcomes of such a participatory, scalable, and sustainable
nation-level advanced infrastructure will have tremendous impact on government, industry, and
academia alike.

description: In the context of a conformal Supergravity (SUGRA) model in the Einstein frame, in which the (next to) minimal supersymmetric standard model can embedded naturally to produce chaotic inflation scenarios, we study properties of gravitino in the cases where it is stable or unstable. In the latter case, we demonstrate that for large dilaton scale factors there is an enhanced magnitude of the gravitino width, when it decays to neutralino dark matter, as compared with the standard SUGRA case. In this context, we discuss the associated consequences as far as Big Bang Nucleosynthesis constraints and avoidance of gravitino overproduction are concerned.

description: In this study, the linear, third-order nonlinear and total refractive index (RI) changes of multi-layered quantum dot (MLQD) and multi-layered quantum anti-dot (MLQAD) with a hydrogenic impurity are calculated. Our numerical results indicate that the RI changes are considerably sensitive to the geometrical parameters of systems and the incident optical intensity. It is observed that by changing the incident photon energy, the RI curves corresponding to MLQAD and MLQD are considerably different in shapes and behaviors. Generally, our results show that MLQAD models have very higher RIs than MLQD models.

description: The plane wave scattering and absorption by finite and infinite gratings of free-space standing infinitely long graphene strips are studied in the THz range. A novel numerical approach, based on graphene surface impedance, hyper-singular integral equations, and the Nystrom method, is proposed. This technique guarantees fast convergence and controlled accuracy of computations. Reflectance, transmittance, and absorbance are carefully studied as a function of graphene and grating parameters, revealing the presence of surface plasmon resonances. Specifically, larger graphene relaxation times increases the number of resonances in the THz range, leading to higher wave transmittance due to the reduced losses; on the other hand an increase of graphene chemical potential up-shifts the frequency of plasmon resonances. It is also shown that a relatively low number of graphene strips (>10) are able to reproduce Rayleigh anomalies. These features make graphene strips good candidates for many applications, including tunable absorbers and frequency selective surfaces.

description: Formalizing causality into terms of (mathematical) logic can allow us to determine with greater precision (1) when it is appropriate to draw causal relationships, (2) whether we can express all the nuanced types of causality, and (3) how we can define the constituent parts of the machinery that drives causal reasoning, among other objectives. While work on (1) and (2) is plentiful and exemplified by Pearl’s structural causal model (SCM), the use of functional dependence logics like Vaananen’s DL based on team semantics to describe reasoning over SCMs is a relatively new tactic toward (3).

With this year’s advent of van Benthem and Baltag’s new functional dependence logic LFD, which takes a more local and modal approach to dependence relationships, I explore in this thesis the expressibility of causality in terms of SCMs in the new system of LFD, mirroring the work done using team semantics, the main result toward this end being the new logic CFD. Comparatively between the two forms of dependence logic discussed, I argue that using the more local CFD to analyze interactions between dependence and causality is more fundamental, fine-grained, and easily controllable, with respect to its global counterpart COD that is based on team semantics. However, I also show that localizing dependence in combined functional-counterfactual dependence logics still leaves various metaphysical problems for analyzing causality that lie outside the scope of said localization. Consequently, I then propose interventional analysis of sets of causal models, rather than singular models, might help solve some of these issues. All throughout, I will show how even in these localized settings, the stratification of causal inference tasks encapsulated in the Pearl Causal Hierarchy hold — and that, in general, logic still backs that correlation (almost) never implies causation.

description: We study the ternary clathrate Pr3Pd20Si6 in specific heat and AC-susceptibility measurements on a high-quality single crystal, distinguishing antiferromagnetic (AFM) and antiferroquadrupolar (AFQ) ordering on two sublattices of inequivalent Pr sites. The specific heat shows the direct involvement of nuclear spin degrees of freedom in the AFM ordering, which is well supported by our calculation of the hyperfine level scheme without adjustable parameters. Pr3Pd20Si6 is therefore one of the rare materials where the nuclear moments are involved in the formation of the magnetic ground state.

description: Aggression in juveniles is an evolutionarily adaptive behavior documented in many species, but the neural mechanisms behind these displays are poorly understood. In humans, the importance of knowing what is happening in the brain during maladaptive aggression is especially key in instances of psychiatric disorders that display as aggressive tendencies in childhood, such as autism spectrum disorders (ASD), schizophrenia, and borderline personality disorder. Mimetic poison frog (Ranitomeya imitator) tadpoles live in small pools with limited resources and have evolved offensive aggressive tendencies towards conspecific tadpoles in defense of these resources. Tadpoles will attack, kill, and cannibalize other tadpoles as a primary resource defense mechanism. I examined the neural basis of neonate aggression in these tadpoles by comparing individuals that were placed in aggressive encounters and individuals placed in an environment with a non-threatening stimulus. I first did a longitudinal study to determine that the tadpoles were most aggressive when they were around five or six weeks old. I then compared patterns of generalized neural activity using immunohistochemical detection of phosphorylated ribosomes and a candidate neuropeptide, arginine vasotocin, which has been implicated in aggression in other vertebrates. Vasotocin cells in the preoptic area of the hypothalamus were not more active in aggressive tadpoles. I then examined neural activation across several brain regions suspected to be involved in aggression, and found that the anterior amygdala had the most neural activation in aggressive tadpoles compared to controls and the other brain regions. Through molecularly profiling active neurons using phosphoTRAP, I identified proopiomelanocortin (POMC), a precursor polypeptide with multiple post-translational peptides, as enriched in active neurons during aggression. Through pharmacological manipulations with the peptides of POMC (aMSH, ACTH, and B-endorphin), I found that a B-endorphin antagonist significantly increased aggressive behavior in tadpoles. Overall, this project is advancing understanding of how aggression is regulated in the juvenile brain.

Particle Acceleration during Magnetorotational Instability in a Collisionless Accretion Disk

Publisher: name: arXiv

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: Particle acceleration during the magnetorotational instability (MRI) in a collisionless accretion disk was investigated by using a particle-in-cell (PIC) simulation. We discuss the important role that magnetic reconnection plays not only on the saturation of MRI but also on the relativistic particle generation. The plasma pressure anisotropy of $p_{\perp} > p_{\para}$ induced by the action of MRI dynamo leads to rapid growth in magnetic reconnection, resulting in the fast generation of nonthermal particles with a hard power-law spectrum. This efficient particle acceleration mechanism involved in a collisionless accretion disk may be a possible model to explain the origin of high energy particles observed around massive black holes.

description: The globular cluster (GC) systems of isolated elliptical galaxies have only recently begun to be studied in detail, and may exhibit morphological connections to the evolutionary histories of their hosts. Here we present the first in a series of wide-field analyses of the GC systems of the isolated ellipticals - Washington C and R photometry of NGC 3585 and NGC 5812 down to ~24 mag. The GC systems are characterised, with each system displaying both the "Universal" blue peak at (C-R)~1.3, and a red peak, but each with differing strengths. The total number of GCs in each system, and their specific frequencies, are estimated. The GC colours and specific frequencies are highly indicative that the host galaxy environment plays a role in shaping its GC system. We produce, and subtract, accurate models of each galaxy, revealing interesting underlying features, including the first definitive evidence that NGC 5812 is interacting with a dwarf companion galaxy. From the galaxy models we also determine surface brightness and colour profiles. Both colour profiles appear quite flat and with (C-R)~1.7 and we discuss the apparent youth of NGC 3585 in the context of this work.

Investigation of Injury- and Paracrine-Induced Sensory Neuron Senescence in a Chronic Pain Model

description: Chronic pain is a significant public health issue and largely affects older members of the population. As people age, senescent cells, which do not divide but resist apoptosis, accumulate in response to stressors, and the senescence-associated secretory phenotype (SASP) may be a contributing and compounding factor to chronic pain. Preliminary data from the Tawfik Lab suggest that sensory neurons, whose cell bodies reside in the dorsal root ganglia (DRG), undergo cellular senescence following peripheral injury. However, it is unknown whether injury directly induces senescence and, further, whether injured senescent cells induce senescence in uninjured, neighboring cells via paracrine senescence. The objectives of this thesis were to (1) investigate cellular senescence of injured and uninjured neurons in the DRG at two chronic timepoints following spared nerve injury (SNI) and (2) investigate whether paracrine senescence occurs after SNI and is potentially exacerbated in aged DRG. RNAscope and immunohistochemistry methods were used to detect senescent cells in the DRG following SNI, and quantitative analysis was performed using ImageJ. A novel method was developed and used to categorize uninjured senescent neurons as paracrine induced based on their proximity to injured IL6+ senescent neurons. At 3 weeks post-SNI, more senescent neurons were observed in the young compared to aged DRG. By 7 weeks post-SNI, the percent of senescent neurons had declined and no difference was observed between young and aged DRG. Also at this timepoint, the ratio of uninjured to injured senescent neurons increased in young and aged DRG, and a slight increase in paracrine-induced senescent neurons was observed in aged tissue. Interestingly, however, paracrine-induced senescent neurons only comprised a minority of uninjured senescent cells. These findings suggest that senescence may be induced in uninjured neurons through processes other than IL6-induced paracrine senescence that have yet to be explored in the DRG.
