“My Sexuality…It Creates A Stress”: Hiv-Related Communication Among Bisexual Black And Latino Men, New York City, Kirk D. Henny, Kathryn Drumhiller, Madeline Y. Sutton, Jose Nanín

Publications and Research

Men who have sex with men and women (including bisexual men) comprise 35% of all men who have sex with men (MSM) in the U.S. It is estimated that 121,800 men who have been bisexually active within the past year are living with HIV in the U.S. Communication about HIV may result in risk-reduction behaviors. However, little is known about the nature or context for HIV prevention communication among bisexual men, particularly for blacks and Hispanic/Latinos who are disproportionately at greater HIV risk. Therefore, we explored patterns and contexts of HIV-related communications occurring within personal social networks among bisexual black …

Doctors As Migration Brokers In The Mandatory Medical Screenings Of Immigrants To The United States, Sofya Aptekar

Publications and Research

Applicants for legal permanent residency in the United States are required to pass a medical screening. Most of these applicants are already living in the United States on non-immigrant and temporary visas and are screened by civil surgeons, physicians designated by the government to look for infectious diseases, incomplete immunization records, and signs that the immigrant will pose a threat or become a public charge. Little is known about the work of these 4000+ physicians, who play a key role as migration brokers in a context where migration control has devolved to non-state actors. I present quantitative analysis of a …

Generating And Repairing Genetically Programmed Dna Breaks During Immunoglobulin Class Switch Recombination, Laura Nicolas, Montserrat Cols, Jee Eun Choi, Jayanta Chaudhuri

Publications and Research

Adaptive immune responses require the generation of a diverse repertoire of immunoglobulins (Igs) that can recognize and neutralize a seemingly infinite number of antigens. V(D)J recombination creates the primary Ig repertoire, which subsequently is modified by somatic hypermutation (SHM) and class switch recombination (CSR). SHM promotes Ig affinity maturation whereas CSR alters the effector function of the Ig. Both SHM and CSR require activation-induced cytidine deaminase (AID) to produce dU:dG mismatches in the Ig locus that are transformed into untemplated mutations in variable coding segments during SHM or DNA double-strand breaks (DSBs) in switch regions during CSR. Within the Ig …

Involuntary Sterilization Among Hiv-Positive Garifuna Women From Honduras Seeking Asylum In The United States: Two Case Reports, Holly G. Atkinson, Deborah Ottenheimer

Publications and Research

Voluntary sterilization is one of the most widely used forms of contraception by women worldwide; however, involuntary sterilization is considered a violation of multiple human rights and grounds for asylum in the United States. Women have been disproportionately affected by this practice. We report two cases of involuntary sterilization in HIV-positive Garifuna women from Honduras who sought asylum in America and were medically evaluated at the request of their attorneys. Key lessons can be drawn from these cases with regard to the importance of medical evaluations in establishing persecution. These include the need for a detailed account of the events …

Bpwrapper: Bioperl-Based Sequence And Tree Utilities For Rapid Prototyping Of Bioinformatics Pipelines, Yözen Hernández, Rocky Bernstein, Pedro Pagan, Levy Vargas, William Mccaig, Girish Ramrattan, Saymon Akther, Amanda Larracuente, Lia Di, Filipe G. Vieira, Weigang Qiu

Publications and Research

Abstract:

Background: Automated bioinformatics workflows are more robust, easier to maintain, and results more reproducible when built with command-line utilities than with custom-coded scripts. Command-line utilities further benefit by relieving bioinformatics developers to learn the use of, or to interact directly with, biological software libraries. There is however a lack of command-line utilities that leverage popular Open Source biological software toolkits such as BioPerl (http://bioperl.org) to make many of the well-designed, robust, and routinely used biological classes available for a wider base of end users.

Results: Designed as standard utilities for UNIX-family operating systems, BpWrapper makes functionality of some of …

Strains Of Bacterial Species Induce A Greatly Varied Acute Adaptive Immune Response: The Contribution Of The Accessory Genome, Uri Sela, Chad W. Euler, Joel Correa Da Rosa, Vincent A. Fischetti

Publications and Research

A fundamental question in human susceptibility to bacterial infections is to what extent variability is a function of differences in the pathogen species or in individual humans. To focus on the pathogen species, we compared in the same individual the human adaptive T and B cell immune response to multiple strains of two major human pathogens, Staphylococcus aureus and Streptococcus pyogenes. We found wide variability in the acute adaptive immune response induced by various strains of a species, with a unique combination of activation within the two arms of the adaptive response. Further, this was also accompanied by a dramatic …

Flp-1 Neuropeptides Modulate Sensory And Motor Circuits In The Nematode Caenorhabditis Elegans, Ingrid Buntschuh, Daniel A. Raps, Ivor Joseph, Christopher Reid, Alexander Chait, Raubern Totanes, Michelle Sawh, Chris Li

Publications and Research

Parasitic nematodes infect over one quarter of the population worldwide, causing morbidity in over one billion people. Current anthelmintic drugs are beginning to lose effectiveness due to the presence of resistant strains. We are interested in the role of neuropeptides, which regulate behaviors in all organisms, as another possible target for anthelmintic drugs. FMRFamide-related peptides (FaRPs) are a family of neuropeptides that are conserved throughout the animal kingdom. In particular, nematodes contain the largest family of FaRPs identified thus far and many of these FaRPs are identical among different nematode species; FaRPs in nematodes are collectively referred to as FLPs …

Publications and Research

Gay, bisexual, and other men who have sex with men (GBM) are disproportionately affected by the HIV epidemic. Despite the promise of pre-exposure prophylaxis (PrEP) in reducing HIV transmission risk, barriers for uptake and persistence exist. We sought to identify whether GBM in a nationwide cohort who have not yet initiated PrEP (n = 906) would prefer to get PrEP-related care from a primary care provider (PCP) compared to a specialist clinic or provider. We then sought to identify their level of interest and factors associated with preference for using home-based PrEP services (i.e., HB-PrEP), defined to participants as conducting …

Mode Of Delivery And Child And Adolescent Psychological Well-Being: Evidence From Hong Kong’S “Children Of 1997” Birth Cohort, Cherry Y. Leung, Gabriel M. Leung, C. Mary Schooling

Publications and Research

Mode of delivery (vaginal or cesarean section) is thought to affect gut microbiota, which in turn may affect psychological well-being. As such, mode of delivery is potentially a modifiable factor for psychological well-being. Here we examined the association of mode of delivery with child and adolescent psychological well-being. We used multivariable linear regression in a populationrepresentative Hong Kong Chinese birth cohort, “Children of 1997,” to examine the adjusted associations of mode of delivery with behavioral problems assessed from parent-reported Rutter score at ~7 (n = 6294) and ~11 years (n = 5598), self-esteem assessed from self-reported Culture-Free Self- Esteem Inventory …

Publications and Research

NLRP10 is a nucleotide-binding oligomerization domain-like receptor that functions as an intracellular pattern recognition receptor for microbial products. Here, we generated a Nlrp10−/− mouse to delineate the role of NLRP10 in the host immune response and found that Nlrp10−/− dendritic cells (DCs) elicited sub-optimal IFNγ production by antigenspecific CD4+ T cells compared to wild-type (WT) DCs. In response to T-cell encounter, CD40 ligation or Toll-like receptor 9 stimulation, Nlrp10−/− DCs produced low levels of IL-12, due to a substantial decrease in NF-κB activation. Defective IL-12 production was also evident in vivo and affected IFNγ production by CD4+ T cells. Upon …

Engineered Aptamers To Probe Molecular Interactions On The Cell Surface, Sana Batool, Sanam Bhandari, Shanell George, Precious Okeoma, Nabeela Van, Hazan E. Zümrüt, Prabodhika Mallikaratchy

Publications and Research

Significant progress has been made in understanding the nature of molecular interactions on the cell membrane. To decipher such interactions, molecular scaffolds can be engineered as a tool to modulate these events as they occur on the cell membrane. To guarantee reliability, scaffolds that function as modulators of cell membrane events must be coupled to a targeting moiety with superior chemical versatility. In this regard, nucleic acid aptamers are a suitable class of targeting moieties. Aptamers are inherently chemical in nature, allowing extensive site-specific chemical modification to engineer sensing molecules. Aptamers can be easily selected using a simple laboratory-based in …
