Triple negative breast cancer (TNBC) is an aggressive form of breast cancer which accounts for 15-20% of this disease and is currently treated with genotoxic chemotherapy. The BCL2 (B-cell lymphoma 2) family of proteins controls the process of mitochondrial outer membrane permeabilization (MOMP), which is required for the activation of the mitochondrial apoptosis pathway in response to genotoxic agents. We previously developed a deterministic systems model of BCL2 protein interactions, DR_MOMP that calculates the sensitivity of cells to undergo mitochondrial apoptosis...

Muhammad Masab, Muhammad W Saif
Patients who are immunocompromised by diseases such as human immunodeficiency virus (HIV) infection are more prone to develop some malignancies such as Kaposi's sarcoma and central nervous system (CNS) lymphomas. Historically, anal squamous cell carcinoma (SCC) was also included on the list as an acquired immunodeficiency syndrome (AIDs)-defining cancer.  Similarly, compromised immune disorders including severe immunosuppression, haematologic malignancies, and solid organ transplantation have been identified as important risk factors for the development of anal SCC...

INTRODUCTION: HIV-1 infection leads to chronic inflammation and to an increased risk of non-AIDS mortality. Our objective was to determine whether AIDS-defining events (ADEs) were associated with increased overall and cause-specific non-AIDS related mortality after antiretroviral therapy (ART) initiation. METHODS: We included HIV treatment-naïve adults from the Antiretroviral Therapy Cohort Collaboration (ART-CC) who initiated ART from 1996 to 2014. Causes of death were assigned using the Coding Causes of Death in HIV (CoDe) protocol...

OBJECTIVE: Accurate preoperative and intraoperative differentiation between primary central nervous system lymphoma (PCNSL) and glioblastoma (GBM) is sometimes difficult. Distinguishing between these tumors during surgery is important because surgical treatment is different between the two tumors. In this study, we established a new method of intraoperative differentiation between PCNSL and GBM using intraoperative flow cytometry (iFC), and we retrospectively tested whether iFC was useful for the intraoperative diagnosis of PCNSL and GBM...

Background: Cancer risk is increased in people living with HIV (PLWH). Improved survival has led to an aging of PLWH. We evaluated the cancer risk in older PLWH (age ≥50 years). Methods: We included data from the HIV/AIDS Cancer Match Study (1996-2012) and evaluated risk of Kaposi sarcoma (KS), non-Hodgkin lymphoma (NHL), Hodgkin lymphoma, and cervical, anal, lung, liver, oral cavity/pharyngeal, breast, prostate, and colon cancers in older PLWH compared to the general population by calculating the standardized incidence ratios (SIRs) and excess absolute risks (EARs)...

BACKGROUND: The diagnosis of primary vitreoretinal lymphoma (PVRL) poses significant difficulties; presenting features are non-specific and confirmation usually necessitates invasive vitreoretinal biopsy. Diagnosis is often delayed, resulting in increased morbidity and mortality. Non-invasive imaging modalities such as spectral domain optical coherence tomography (SD-OCT) offer simple and rapid aids to diagnosis. We present characteristic SD-OCT images of patients with biopsy-positive PVRL and propose a number of typical features, which we believe are useful in identifying these lesions at an early stage...

Spermatocytic seminoma (or, alternatively, spermatocytic tumor) of the testis is rare and errors in pathologic diagnosis are still made. As it has a good prognosis, except when it, rarely, undergoes sarcomatous transformation, accurate diagnosis and differentiating it from usual seminoma and other malignant neoplasms such as lymphoma are crucial. To potentially contribute information of diagnostic aid we reviewed the largest series of cases reported to date to characterize in detail their histologic spectrum...

OBJECTIVE: Brentuximab vedotin (BV) is an FDA approved anti-CD30 antibody drug conjugate potently active in Hodgkin lymphoma (HL). Trials of BV with doxorubicin, vinblastine, and dacarbazine (AVD-BV) excluded patients with HIV. We studied the safety of (AVD-BV) in newly diagnosed HIV-associated classical Hodgkin lymphoma (HIV-cHL). DESIGN AND METHODS: Patients diagnosed with Stage II-IV HIV-cHL received AVD-BV on days 1 and 15 every 28 days for 6 cycles. Anti-HIV medications with strong CYP3A4 inhibition were excluded...

Activation-induced cytidine deaminase (AID) plays important roles in the development of diffuse large B-cell lymphoma (DLBCL); however, its prognostic value remains controversial. Here, we evaluated AID expression in 71 DLBCL patients treated with R-CHOP by immunohistochemistry and investigated its prognostic significance. AID expression was detected in 40.8% of DLBCL samples and associated with IRF4 expression. Notably, AID expression correlated with shorter progression-free survival and overall survival for patients with high (3-5) international prognostic index (IPI) score...

Objectives: Chronic recurrent multifocal osteomyelitis (CRMO), the most severe form of chronic nonbacterial osteomyelitis (CNO), is an autoinflammatory bone disorder. In the absence of diagnostic criteria or biomarkers, CNO/CRMO remains a diagnosis of exclusion. The aim of this study was to identify biomarkers for diagnosing multifocal disease (CRMO). Study design: Sera from 71 pediatric CRMO patients, 11 patients with osteoarticular infections, 62 patients with juvenile idiopathic arthritis (JIA), 7 patients with para-infectious or reactive arthritis, and 43 patients with acute leukemia or lymphoma, as well as 59 healthy individuals were collected...

Background: When scoring 18F-Fluorodeoxyglucose (FDG) positron emission tomography (PET) with the Deauville scale (DS), the quantification of tumor and reference organs limits the problem of optical misinterpretation. Compared to conventional reconstruction algorithms, point spread function (PSF) modeling significantly increases standardized uptake values (SUVs) in tumors but only moderately in the liver, which could affect the DS. We investigated whether the choice of the reconstruction algorithm affects the DS and whether discordances affect the capability of FDG PET to stratify lymphoma patients...

The northern sea otter inhabits coastal waters of the northern Pacific Ocean and is the largest member of the Mustelidae family. DNA sequencing methods that utilize microfluidic partitioned and non-partitioned library construction were used to establish the sea otter genome. The final assembly provided 2.426 Gbp of highly contiguous assembled genomic sequences with a scaffold N50 length of over 38 Mbp. We generated transcriptome data derived from a lymphoma to aid in the determination of functional elements...

Culture media modifications, including the addition of various factors, are important for the in vitro production of oocytes and embryos. In this study, we investigated the effects of lysophosphatidic acid (LPA) on porcine embryo development. Porcine parthenogenetic embryos were cultured with 0, 0.1, 1, and 10 μM LPA for 7 days, or cultured in basic medium until Day 4 and then treated with LPA from Days 4 to 7. No difference in the in vitro development of embryos cultured with LPA for 7 days was observed. Conversely, rates of blastocyst and over-expanded blastocyst formation were higher in the 0...

PURPOSE: Our purpose was to evaluate the diagnostic and prognostic value of skeletal textural features (TFs) on baseline FDG PET in diffuse large B cell lymphoma (DLBCL) patients. METHODS: Eighty-two patients with DLBCL who underwent a bone marrow biopsy (BMB) and a PET scan between December 2008 and December 2015 were included. Two readers blinded to the BMB results visually assessed PET images for bone marrow involvement (BMI) in consensus, and a third observer drew a volume of interest (VOI) encompassing the axial skeleton and the pelvis, which was used to assess skeletal TFs...

Kaposi's sarcoma-associated herpesvirus (KSHV) is the causative agent of primary effusion lymphoma (PEL) and Kaposi's sarcoma. PEL is a type of non-Hodgkin's B-cell lymphoma, affecting immunosuppressed individuals, such as post-transplant or AIDS patients. However, since PEL is resistant to chemotherapeutic regimens, new effective treatment strategies are required. Arctigenin, a natural lignan compound found in the plant Arctium lappa, has been widely investigated as a potential anticancer agent in the clinical setting...

The aim of this study was to establish nomograms, based on significant clinicopathologic parameters, for predicting the overall survival (OS) and the cancer-specific survival (CSS) of patients with classical Hodgkin lymphoma (CHL). The data of 43,330 CHL patients, diagnosed between 1983 and 2014, were obtainedfrom the database of the Surveillance, Epidemiology, and End Results (SEER) program. These patients were randomly divided into training (n = 30,339) and validation (n = 12,991) cohorts. The Kaplan-Meier method and Cox proportional hazards regression model were used to evaluate the prognostic effects of multiple clinicopathologic parameters on survival...
