Molly L Bristol, Dipon Das, Iain M Morgan
Human papillomaviruses (HPV) require the activation of the DNA damage response (DDR) in order to undergo a successful life cycle. This activation presents a challenge for the virus and the infected cell: how does viral and host replication proceed in the presence of a DDR that ordinarily arrests replication; and how do HPV16 infected cells retain the ability to proliferate in the presence of a DDR that ordinarily arrests the cell cycle? This raises a further question: why do HPV activate the DDR? The answers to these questions are only partially understood; a full understanding could identify novel therapeutic strategies to target HPV cancers...

HIV infection and alcohol use disorder are associated with deficits in neurocognitive function. Emerging evidence points to pro-inflammatory perturbations of the gut-brain axis as potentially contributing to neurocognitive impairment in the context of HIV and chronic heavy alcohol use. This study examined whether plasma markers of microbial translocation (LPS) from the gastrointestinal tract and related immune activation (sCD14, EndoCAb) were associated with neurocognition in 21 men living with HIV who were virally suppressed on antiretroviral therapy...

The current study identified alcohol and cannabis use trajectories among a sample of Mexican-origin youth and examined cultural and familial correlates from childhood to adolescence. Mexican-origin youth (N = 674) from Northern California were assessed annually from ages 10 to 17 (8 waves). Latent class growth modeling examined variability in developmental trajectories for last 3-month alcohol and cannabis use frequency. Analyses also examined between-trajectory differences in youth's cultural practices and values, family cultural conflict, general parent-child conflict, and parental monitoring at 4 time points from ages 10 to 16...

A series of cobalt bis(benzenedithiolate) complexes with varying benzenedithiolate (general abbreviation: bdt(2-)) ring substitutions (S2C6X4(2-)) were prepared and adsorbed on inexpensive electrodes composed of (a) reduced graphene oxide (RGO) electrodeposited on fluorine-doped tin oxide (FTO) and (b) highly ordered pyrolytic graphite (HOPG). The catalyst-adsorbed electrodes are characterized by X-ray photoelectron spectroscopy. Catalyst loading across the ligand series improved notably with increasing halide substitution [from 2...

Aminoglycoside antibiotics are widely used for the treatment of life-threatening bacterial infections, but cause permanent hearing loss in a substantial proportion of treated patients. The sensory hair cells of the inner ear are damaged following entry of these antibiotics via the mechano-electrical transducer (MET) channels located at the tips of the hair cell's stereocilia. d-Tubocurarine (dTC) is a MET channel blocker that reduces the loading of gentamicin-Texas Red (GTTR) into rat cochlear hair cells and protects them from gentamicin treatment...

REVIEW
Justin T Brady, Molly E Kelly, Sharon L Stein
Social media is a source of news and information for an increasing portion of the general public and physicians. The recent political election was a vivid example of how social media can be used for the rapid spread of "fake news" and that posts on social media are not subject to fact-checking or editorial review. The medical field is susceptible to propagation of misinformation, with poor differentiation between authenticated and erroneous information. Due to the presence of social "bubbles," surgeons may not be aware of the misinformation that patients are reading, and thus, it may be difficult to counteract the false information that is seen by the general public...

Conspicuous consumption refers to the phenomenon where individuals purchase goods for signalling social status, rather than for its inherent functional value. This study (n = 166 male participants) investigated how the outcome of a social competition influenced conspicuous consumption, and its association with competition-induced testosterone reactivity. Winning a competition increased both explicit and implicit preferences for higher-status vs. lower-status products, using both natural stimuli (prestigious cars) and laboratory-tagged stimuli of matched value (university T-shirts)...

Nuclear receptor corepressor 1 (NCoR1) is considered to be the major corepressor that mediates ligand-independent actions of the thyroid hormone receptor (TR) during development and in hypothyroidism. We tested this by expressing a hypomorphic NCoR1 allele (NCoR1ΔID), which cannot interact with the TR, in Pax8-KO mice, which make no thyroid hormone. Surprisingly, abrogation of NCoR1 function did not reverse the ligand-independent action of the TR on many gene targets and did not fully rescue the high mortality rate due to congenital hypothyroidism in these mice...

PURPOSE: To investigate the ability of the propensity score (PS) to reduce confounding bias in the presence of nondifferential misclassification of treatment, using simulations. METHODS: Using an example from the pregnancy medication safety literature, we carried out simulations to quantify the effect of nondifferential misclassification of treatment under varying scenarios of sensitivity and specificity, exposure prevalence (10%, 50%), outcome type (continuous and binary), true outcome (null and increased risk), confounding direction, and different PS applications (matching, stratification, weighting, regression), and obtained measures of bias and 95% confidence interval coverage...

Transgendered individuals can suffer a significant amount of psychological distress which can be alleviated through hormonal treatments and/or gender-affirming surgery. The World Professional Association for Transgender Health (WPATH) considers a hysterectomy and BSO medically necessary gender-affirming procedures for the interested transgendered male. Several surgical approaches have been described in the literature, the majority of which endorse a laparoscopic approach. This review will summarize the available literature on surgical techniques in addition to reporting our institutional outcomes using a novel 2-port laparoscopic approach...

Many cancer treatments, such as those for managing recalcitrant tumors like pancreatic ductal adenocarcinoma, cause off-target toxicities in normal, healthy tissue, highlighting the need for more tumor-selective chemotherapies. β-Lapachone is bioactivated by NAD(P)H:quinone oxidoreductase 1 (NQO1). This enzyme exhibits elevated expression in most solid cancers and therefore is a potential cancer-specific target. β-Lapachone's therapeutic efficacy partially stems from the drug's induction of a futile NQO1-mediated redox cycle that causes high levels of superoxide, then peroxide formation, which damages DNA and causes hyperactivation of poly (ADP-ribose) polymerase (PARP), resulting in extensive NAD+/ATP depletion...

MEDI-570 is a fully human afucosylated monoclonal antibody (MAb) against Inducible T-cell costimulator (ICOS), highly expressed on CD4+ T follicular helper (TFH) cells. Effects of MEDI-570 were evaluated in an enhanced pre-postnatal development toxicity (ePPND) study in cynomolgus monkeys. Administration to pregnant monkeys did cause any abortifacient effects. Changes in hematology and peripheral blood T lymphocyte subsets in maternal animals and infants and the attenuated infant IgG immune response to keyhole limpet hemocyanin (KLH) were attributed to MEDI-570 pharmacology...
