Acne is a chronic inflammatory skin disease that is the most common skin disorder in the United States. Therapy targets the four factors responsible for lesion formation: increased sebum production, hyperkeratinization, colonization by Propionibacterium acnes, and the resultant inflammatory reaction. Treatment goals include scar prevention, reduction of psychological morbidity, and resolution of lesions.

Article Synopsis
  • The study investigates the role of brain-derived neurotrophic factor (BDNF) in psychiatric disorders by analyzing genomic data from a large group of subjects with and without mental health issues.
  • Researchers found 5 individuals with psychiatric symptoms who had a specific genomic deletion that included the BDNF gene, which was not present in unaffected controls.
  • The findings suggest that a partial loss of the BDNF region could be linked to various psychiatric conditions, such as anxiety and mood disorders.

Radiation has long been the standard of care for many types of cancer. It is employed to locally eradicate tumor cells as well as alter tumor stroma with either curative or palliative intent. Radiation-induced cell damage is an immunologically active process in which danger signals are released that stimulate immune cells to phagocytose and present locally released tumor-associated antigens (TAAs).

Objective: Cross-sectional research indicates high rates of mental health concerns among youth with perinatal HIV infection (PHIV), but few studies have examined emerging psychiatric symptoms over time.

Methods: Youth with PHIV and peer comparisons who were HIV-exposed but uninfected or living in households with HIV-infected family members (HIV-affected) and primary caregivers participated in a prospective, multisite, longitudinal cohort study. Groups were compared for differences in the incidence of emerging psychiatric symptoms during 2 years of follow-up and for differences in psychotropic drug therapy.

Chromosomal rearrangements involving the anaplastic lymphoma kinase gene (ALK) at 2p23 result in fusion with various partner genes leading to aberrant production of oncogenic protein products in multiple tumor types. Recently, the ALK protein inhibitor crizotinib was shown to be an effective therapy in patients with ALK-rearranged non-small cell lung cancer. The goal of this study was to determine the frequency of ALK alterations in adult renal cell carcinoma (RCC) and define associated clinicopathologic features and outcome.

Article Synopsis
  • The Hubble Deep Field has allowed astronomers to observe thousands of galaxies over time, with one notable discovery being HDF 850.1, which emits at a wavelength sensitive to star formation.
  • Researchers have now determined that HDF 850.1 has a redshift of z = 5.183, placing it in a galaxy cluster formed just 1.1 billion years after the Big Bang.
  • Despite identifying its distance and mass, HDF 850.1 still lacks a visible starlight counterpart, making it a mysterious object in cosmic observations.*

Therapeutic cancer vaccines are a unique treatment modality in that they initiate a dynamic process of activating the host immune system, which can then be exploited by concurrent or subsequent therapies. The addition of immunotherapy to standard-of-care cancer therapies has shown evidence of efficacy in preclinical models and in the clinical setting. This review examines the preclinical and clinical interactions between vaccine-mediated tumor-specific immune responses and local radiation, systemic chemotherapy, or select small molecule inhibitors, as well as the potential synergy between these modalities.

In 2010, Senate Bill 1309 included language to repeal an existing Arizona law that enables minors younger than 18 years of age to seek diagnosis and treatment of sexually transmitted diseases (STDs) without parental consent. Numerous implications were identified that would have stemmed from parental consent provisions originally proffered in Senate Bill 1309. These implications included diminished access to essential health services among minors, exacerbated existing health disparities, increased health-care spending costs, and thwarted efforts to curb the spread of STDs.

Background: Astrocytes are an integral component of the blood-brain barrier (BBB) which may be compromised by ischemic or traumatic brain injury. In response to trauma, astrocytes increase expression of the endopeptidase matrix metalloproteinase (MMP)-9. Compromise of the BBB leads to the infiltration of fluid and blood-derived proteins including albumin into the brain parenchyma.

Phosphaturic mesenchymal tumor of mixed connective tissue type is a rare, histologically distinctive mesenchymal neoplasm associated with tumor-induced osteomalacia resulting from production of the phosphaturic hormone fibroblast growth factor 23. Because of its rarity, specific genetic alterations that contribute to the pathogenesis of these tumors have yet to be elucidated. Herein, we report the abnormal karyotypes from 2 cases of confirmed phosphaturic mesenchymal tumor of mixed connective tissue type.

Renal cell carcinoma (RCC) with chromosomal rearrangement of transcription factor for immunoglobulin heavy-chain enhancer 3 (TFE3) at Xp11.2 is a distinct subtype that was initially described in children and has been reported to display an indolent course. Recent reports have identified RCC with TFE3 rearrangements in adults and have suggested a more aggressive course in this population.

True long-term nonprogressors (LTNPs)/elite controllers (ECs) maintain durable control over HIV replication without antiretroviral therapy. Herein we describe 4 unique persons who were distinct from conventional LTNPs/ECs in that they had extraordinarily low HIV burdens and comparatively weak immune responses. As a group, typical LTNPs/ECs have unequivocally reactive HIV-1 Western blots, viral loads below the lower threshold of clinical assays, low levels of persistent viral reservoirs, an over-representation of protective HLA alleles, and robust HIV-specific CD8(+) T-cell responses.

The decade following the terrorist attacks on September 11, 2001, and ensuing anthrax exposures that same fall has seen significant legal reforms designed to improve biopreparedness nationally. Over the past 10 years, a transformative series of legal changes have effectively (1) rebuilt components of federal, state, and local governments to improve response efforts; (2) created an entire new legal classification known as "public health emergencies"; and (3) overhauled existing legal norms defining the roles and responsibilities of public and private actors in emergency response efforts. The back story as to how law plays an essential role in facilitating biopreparedness, however, is pocked with controversies and conflicts between law- and policymakers, public health officials, emergency managers, civil libertarians, scholars, and others.

Background: Elevated serum interleukin 7 (IL-7) levels are observed in lymphopenic conditions, including idiopathic CD4 lymphopenia (ICL), which is characterized by CD4 lymphopenia in the absence of human immunodeficiency virus infection or other known immunodeficiency.

Methods: To test whether defective IL-7 signaling could be an etiologic or contributing factor in ICL, peripheral blood mononuclear cells from patients with ICL (median CD4 T-cell count, 160 cells/μL) and healthy controls (median CD4 T-cell count, 582 cells/μL) were evaluated for expression of IL-7Rα chain (CD127) and intracellular phosphorylated STAT-5 (a marker of γc cytokine signaling) after cytokine stimulation. Gene expression was analyzed by real-time polymerase chain reaction following IL-7 stimulation.

Uterine leiomyomata (UL), the most common neoplasm in reproductive-age women, are classified into distinct genetic subgroups based on recurrent chromosome abnormalities. To develop a molecular signature of UL with t(12;14)(q14-q15;q23-q24), we took advantage of the multiple UL arising as independent clonal lesions within a single uterus. We compared genome-wide expression levels of t(12;14) UL to non-t(12;14) UL from each of nine women in a paired analysis, with each sample weighted for the percentage of t(12;14) cells to adjust for mosaicism with normal cells.

Chemotherapy with platinum doublets, including cisplatin plus vinorelbine, is standard of care for non-small-cell lung cancer. Sublethal exposure to certain chemotherapeutic agents has been demonstrated to alter the phenotype or biology of human tumor cells, rendering them more susceptible to cytotoxic T lymphocyte (CTL)-mediated lysis. The effects of cisplatin/vinorelbine on tumor sensitivity to T-cell cytotoxicity and its molecular mechanisms, however, have not been fully elucidated.

A child whose features are consistent with Pallister-Killian syndrome (PKS) did not have detectable tetrasomy 12p due to an additional isochromosome 12p in an unstimulated blood specimen by interphase FISH or array CGH analysis. The diagnosis of PKS was made through these methods solely in a skin biopsy specimen. To determine the sensitivity of our array CGH platform to tetrasomy 12p mosaicism, dilutions of DNA from both the child's skin fibroblasts and a PKS cell line were analyzed.
