A Chandra X-Ray study of the dense globular cluster Terzan 5
(American Astronomical Society, 2003)We report a Chandra ACIS-I observation of the dense globular cluster Terzan 5. The previously known transient low-mass X-ray binary (LMXB) EXO 1745-248 in the cluster entered a rare high state during our 2000 August ... -
A Chandra X‐Ray Study of the Globular Cluster M80

A Characteristic Division Between the Fueling of Quasars and Seyferts: Five Simple Tests
(American Astronomical Society, 2009)Given the existence of the M-BH-sigma relation, models of self-regulated black hole (BH) growth require both a fuel supply and concomitant growth of the host bulge to deepen the central potential, or else the system will ... -
A Chimeric Protein of Simian Immunodeficiency Virus Envelope Glycoprotein gp140 and Escherichia coli Aspartate Transcarbamoylase
(American Society for Microbiology, 2004)The envelope glycoproteins of the human immunodeficiency virus and the related simian immunodeficiency virus (SIV) mediate viral entry into host cells by fusing viral and target cell membranes. We have reported expression, ... -
A Cholera Toxin B-subunit Variant That Binds Ganglioside G M1 but Fails to Induce Toxicity
(American Society for Biochemistry and Molecular Biology, 2001) -
A chromatin localization screen reveals poly (ADP ribose)-regulated recruitment of the repressive polycomb and NuRD complexes to sites of DNA damage
(National Academy of Sciences, 2010)Many proteins that respond to DNA damage are recruited to DNA lesions. We used a proteomics approach that coupled isotopic labeling with chromatin fractionation and mass spectrometry to uncover proteins that associate with ... -
A Chrysin Derivative Suppresses Skin Cancer Growth by Inhibiting Cyclin-dependent Kinases
(American Society for Biochemistry and Molecular Biology, 2013)Chrysin (5,7-dihydroxyflavone), a natural flavonoid widely distributed in plants, reportedly has chemopreventive properties against various cancers. However, the anticancer activity of chrysin observed in in vivo studies ... -
A Clinician-administered Severity Rating Scale for Illness Anxiety: Development, Reliability, and Validity of the H-ybocs-m
(2012)Background Clinician-administered measures to assess severity of illness anxiety and response to treatment are few. The authors evaluated a modified version of the hypochondriasis-Y-BOCS (H-YBOCS-M), a 19-item, semistructured, ... -
A Clock-Phased Sigma Factor Cascade Is Required for Global Circadian Transcriptional Rhythms in Cyanobacteria
(2017-09-07)The circadian clock of the cyanobacterium Synechococcus elongatus PCC 7942 drives oscillations in global mRNA transcript abundances with 24 h periodicity under continuous light conditions. The transcription factor RpaA ... -
A Closer Lens on Gut Health, Stress, Mental Health in the Middle East: A Focus on Kuwait
(2021-11-08)Generalized Anxiety Disorder (GAD), is a highly prevalent and disruptive disorder as it is highly resistant to both pharmacological and psychological treatments (Borkovec et al., 2002), and has a high financial burden on ... -
A Cohort Study of Tumoral LINE-1 Hypomethylation and Prognosis in Colon Cancer
(Oxford University Press, 2008)Genome-wide DNA hypomethylation plays has an important role in genomic instability and colorectal carcinogenesis. However, the relationship between cellular DNA methylation level and patient outcome remains uncertain. Using ... -
A Combinatorial Maf Transcription Factor Code Establishes Synaptic Heterogeneity Critical for Normal Hearing Function
(2023-01-18)Spiral ganglion neuron (SGN) synaptic, functional, and molecular diversity is critical for hearing function. Heterogeneous inner hair cell (IHC)-SGN synapses transduce complex sound information from the ear to the brain. ... -
A Combined Mastery Learning and Flipped-Classroom Approach: The Effect on Self-Assessment of Leadership Skills
(2022-05-12)Abstract Strong leadership is associated with better performance of individuals, teams, and organizations. This project aimed to determine whether a flipped-classroom and mastery-learning curriculum is associated with ... -
A Common 8q24 Variant in Prostate and Breast Cancer from a Large Nested Case-Control Study
(American Association for Cancer Research, 2007)Two recent studies independently identified polymorphisms in the 8q24 region, including a single nucleotide polymorphism (rsl447295), strongly associated with prostate cancer risk. Here, we replicate the overall association ... -
A Comparative Analysis of Engagement Methodologies in Community Resilience Initiatives
(2022-05-12)Millions of dollars, not to mention invaluable community trust and energy, are wasted every year on ineffective community redevelopment programs and projects that fail to live up to their goals due to lack of community ... -
A Comparative Analysis of Incident Reporting Lag Times in Academic Medical Centres in Japan and the USA
