Janusz Edward Jacak
Recent experimental progress in Hall measurements in bilayer graphene in the so-called open-face configuration of boron nitride encapsulated samples, together with the earlier technique of suspended samples, allows for precise observation of the fractional quantum Hall effect (FQHE) in all 4 subbands of the Lowest Landau level (with n = 0 and n = 1) and in the next LL subbands (with n = 2) in the bilayer system. Many newly observed FQHE features do not agree with a conventional model of composite fermions and reveal a different hierarchy in comparison to monolayer graphene or GaAs 2DEG...

A helical type edge state, which is generally supported only on graphene with zigzag boundaries, is found to also appear in armchair graphene nanoribbons in the presence of intrinsic spin-orbit coupling and a suitable strain. At a critical strain, there appears a quantum phase transition from a quantum spin Hall state to a trivial insulator state. Further investigation shows that the armchair graphene nanoribbons with intrinsic spin-orbit coupling, Rashba spin-orbit coupling, effective exchange fields and strains also support helical-like edge states with a unique spin texture...

Many drugs have progressed through preclinical and clinical trials and have been available - for years in some cases - before being recalled by the FDA for unanticipated toxicity in humans. One reason for such poor translation from drug candidate to successful use is a lack of model systems that accurately recapitulate normal tissue function of human organs and their response to drug compounds. Moreover, tissues in the body do not exist in isolation, but reside in a highly integrated and dynamically interactive environment, in which actions in one tissue can affect other downstream tissues...

Allogeneic hematopoietic cell transplant advances for sickle cell disease improve outcomes, but limited healthcare utilization analysis exists. We hypothesized that early transplant (age < 10 years) improves outcomes and decreases healthcare utilization compared to late. We performed a retrospective study of US children transplanted for sickle cell during 2000-2013 using two large databases. Univariate and Cox models estimated associations between demographics, sickle cell severity, and transplant-related variables on mortality and chronic graft versus-host-disease; while, Wilcoxon, Kruskal-Wallis, or linear trend tests estimated against healthcare utilization...

Both babies and their parents may experience a stay in the newborn intensive care unit (NICU) as a traumatic or a 'toxic stress,' which can lead to dysregulation of the hypothalamic-pituitary-adrenal axis and ultimately to poorly controlled cortisol secretion. Toxic stresses in childhood or adverse childhood experiences (ACEs) are strongly linked to poor health outcomes across the lifespan and trauma-informed care is an approach to caregiving based on the recognition of this relationship. Practitioners of trauma-informed care seek to understand clients' or patients' behaviors in light of previous traumas they have experienced, including ACEs...

The goal of the current study was to examine the feasibility of a telepractice intervention to improve phonological awareness skills in children with hearing loss as compared to a conventional in-person intervention. Twenty children with hearing loss participated in this study. Two groups of ten children each received a supplemental phonological awareness intervention either via telepractice or an in-person service delivery model. Within each of the two groups, five children were enrolled in preschool or kindergarten and five children were enrolled in first or second grade...

BACKGROUND: Differences in DNA methylation can arise as epialleles, which are loci that differ in chromatin state and are inherited over generations. Epialleles offer an additional source of variation that can affect phenotypic diversity beyond changes to nucleotide sequence. Previous research has looked at the rate at which spontaneous epialleles arise but it is currently unknown how they are maintained across generations. RESULTS: We used two Arabidopsis thaliana mutation accumulation (MA) lines and determined that over 99...

REVIEW
Anu Asnaani, Brittany Hall-Clark
Our understanding of demographic specifications that put certain individuals at greater risk for trauma exposure and subsequent development of post-traumatic stress disorder (PTSD) has grown significantly over the past few decades. This brief review specifically examines the studies exploring the potential influence of ethnocultural and racial group status on trauma exposure and PTSD, with a focus on findings published recently in the past five years. We first provide a brief review of current epidemiological data examining associations among ethnicity/culture/race and trauma exposure/PTSD...

REVIEW
Suzanne L Pineles, Kimberly A Arditte Hall, Ann M Rasmusson
Whereas research supports the existence of a single posttraumatic stress disorder (PTSD) phenotype across women and men, there may be important gender differences in the pathophysiology of, or mechanisms underlying, the disorder. This paper reviews recent literature on gender differences in emotional, cognitive, and neurobiological factors, and their relations with PTSD and relevant comorbidities. Key findings and limitations from both human and animal studies are discussed. Overall, more work is needed that utilizes objective measures in addition to self-report...

Four recent publications reported the role of PD-L1 expression on host versus malignant cells within the tumor for PD-1/PD-L1 checkpoint blockade therapy. All four research groups harmoniously report: PD-L1 expressed by both host as well as tumor cells are capable of suppressing T cell functions. Thus, checkpoint therapy can be effective, if malignant cells do not express PD-L1.

The developmental accumulation of proliferative germ cells in the C. elegans hermaphrodite is sensitive to the organismal environment. Previously, we found that the TGFβ signaling pathway links the environment and proliferative germ cell accumulation. Neuronal DAF-7/TGFβ causes a DAF-1/TGFβR signaling cascade in the gonadal distal tip cell (DTC), the germline stem cell niche, where it negatively regulates a DAF-3 SMAD and DAF-5 Sno-Ski. LAG-2, a founding DSL ligand family member, is produced in the DTC and activates the GLP-1/Notch receptor on adjacent germ cells to maintain germline stem cell fate...

BACKGROUND: Metabolic syndrome (MetS) is strongly associated with cardiovascular disease. With MetS prevalence rates increasing in the U.S. population, prevention efforts have largely focused on diet and exercise interventions. Before retirement, military service members have met fitness requirements for at least 20 years, and have lower MetS rates compared to age-matched U.S. population controls (23.4% vs. 39.0%), which suggests a protective effect of the lifestyle associated with military service...

Yoga practice is known to improve well-being and decrease stress. However, acute yoga is understudied. This study investigated the effects of two different types of yoga on affect and salivary cortisol levels in college women. Thirty-three women aged 18-30 years each completed 1-hour sessions of power yoga and stretch yoga. Measures of affect and salivary cortisol were assessed before, during, and after each session. Participants perceived power yoga to be more pleasurable and energizing. Salivary cortisol significantly decreased after both yoga sessions...
