A new framework has been introduced in this paper for tumor radiosensitization and therapy response monitoring using low-frequency ultrasound. Human fibrosarcoma xenografts grown in severe combined immunodeficiency (SCID) mice (n = 108) were treated using ultrasound-stimulated microbubbles at various concentration and exposed to different doses of radiation. Low-frequency ultrasound radiofrequency (RF) data were acquired from tumors prior to and at different times after treatment. Quantitative ultrasound (QUS) techniques were applied to generate spectral parametric maps of tumors...

IntrathymicTcell development is a complex process that depends upon continuous guidance from thymus stromal cell microenvironments. The thymic epithelium within the thymic stroma comprises highly specialized cells with a high degree of anatomic, phenotypic, and functional heterogeneity. These properties are collectively required to bias thymocyte development toward production of self-tolerant and functionally competent T cells. The importance of thymic epithelial cells (TECs) is evidenced by clear links between their dysfunction and multiple diseases where autoimmunity and immunodeficiency are major components...

Viral protein U (Vpu) is a type-III integral membrane protein encoded by Human Immunodeficiency Virus-1 (HIV- 1). It is expressed in infected host cells and plays several roles in viral progeny escape from infected cells, including down-regulation of CD4 receptors. But key structure/function questions remain regarding the mechanisms by which the Vpu protein contributes to HIV-1 pathogenesis. Here we describe expression of Vpu in bacteria, its purification and characterization. We report the successful expression of PelB-Vpu in Escherichia coli using the leader peptide pectate lyase B (PelB) from Erwinia carotovora...

OBJECTIVES: Tuberculosis (TB) is a major cause of morbidity and mortality in human immunodeficiency virus (HIV) infected patients. However, anti-tuberculosis drugs can cause cutaneous adverse drug reactions (CADRs). This study was conducted to evaluate differences in CADR incidence between low and high CD4 cell count in patients with low and high CD4 cell count and to identify other risk factors for CADR in HIV-TB co-infected patients. DESIGN: In a retrospective cohort of adult HIV-TB co-infected patients receiving standard anti-tuberculosis treatment between January 2008 and December 2015 at Vajira Hospital, Bangkok, Thailand, baseline demographic, clinical characteristics and factors associated with CADRs, including CD4 cell count status, were collected...

SETTING: A third of the world's population has latent tuberculous infection (LTBI). Current TB diagnostics used in developing countries are ineffective and are unable to distinguish LTBI from active TB. Identifying biomarkers that could aid in the early detection of TB and in distinguishing TB states could be a major breakthrough in global TB control. OBJECTIVE: To identify potential immune biomarkers to distinguish active TB from LTBI. DESIGN: A cross-sectional study was conducted among 19 active TB patients, 8 TB-negative individuals (controls) and 16 LTBI non-human immunodeficiency virus infected individuals in Nairobi, Kenya...

This study seeks to generate analytic insights into risk management and probability of an identifiable primary immunodeficiency defect. The Jeffrey Modell Centers Network database, Jeffrey Modell Foundation's 10 Warning Signs, the 4 Stages of Testing Algorithm, physician-reported clinical outcomes, programs of physician education and public awareness, the SPIRIT® Analyzer, and newborn screening, taken together, generates P values of less than 0.05%. This indicates that the data results do not occur by chance, and that there is a better than 95% probability that the data are valid...

BACKGROUND: The meningococcal capsule is an important virulence determinant. Unencapsulated meningococci lacking capsule biosynthesis genes and containing the capsule null locus (cnl) are predominantly non-pathogenic. Rare cases of invasive meningococcal disease caused by cnl isolates belonging to sequence types (ST) and clonal complexes (cc) ST-845 (cc845), ST-198 (cc198), ST-192 (cc192) and ST-53 (cc53) have been documented. The clinical significance of these isolates however remains unclear...

Autoimmune polyendocrinopathy, candidiasis and ectodermal dystrophy (APECED) is a rare but devastating primary immunodeficiency disease caused by loss-of-function mutations in autoimmune regulator (AIRE) gene on chromosome 21q22.3. The clinical spectrum of the disease is characterized by a wide heterogeneity because of autoimmune reactions toward different endocrine and non-endocrine organs. Here, we report a 17-year-old Turkish girl diagnosed with APECED at 9 years in whom a novel homozygote mutation in AIRE gene p...

Outbreaks of acute Chagas disease (ACD) in northern Brazil can be caused by the ingestion of unprocessed açai pulp contaminated with Trypanosoma cruzi . The aim of this study was to determine the minimum thermal process required to inactivate T. cruzi in açai pulp. Trypomastigotes (100,000) of T. cruzi Y strain were added to 0.15 M NaCl or açai pulp and continuously mixed while being heat treated at 37 to 49°C for up to 1 h. When necessary, parasites were separated from açai pulp by forced sieving. Inocula were administrated intraperitoneally in inbred immunodeficient C...

African-American males ages 13 through 24 are disproportionately affected by sexually transmitted infections (STIs) and human immunodeficiency virus (HIV), accounting for over half of all HIV infections in this age group in the United States. Clear communication between African-American parents and their youth about sexual health is associated with higher rates of sexual abstinence, condom use, and intent to delay initiation of sexual intercourse. However, little is known about African-American fathers' perceptions of what facilitates and inhibits sexual health communication with their preadolescent and adolescent sons...

Infectious disease continues to adversely affect populations in low- and middle-income countries. Investments in solutions often focus on technology, yet health-care workers remain in short supply. Nurses are the largest cadre of health-care workers and are largely responsible for patient care around the world. In fact, it is estimated that nurses care for nine out of every 10 patients seen. Importantly, sound nursing science contributes to solutions that directly impact patient care, especially, those that pertain to infectious disease...
