Characteristic chromosomal translocations are found to be associated with subtypes of B-cell non-Hodgkin lymphoma (NHL), for example t(8;14)(q24;q32) and Burkitt lymphoma, t(14;18)(q32;q21) and follicular lymphoma, and t(11;14)(q13;q32) in mantle cell lymphoma. Only few recurrent cytogenetic aberrations have been identified in the T-cell NHL and the best known is the ALK gene translocation t(2;5)(p23;q35) in anaplastic large cell lymphoma. Since lymph node or other tissue is seldom submitted for conventional cytogenetics study, alternative approaches for translocation detection are polymerase chain reaction (PCR) or fluorescence in situ hybridization (FISH)...

An 85-year-old woman was hospitalized by emergency for an acute Stanford type A aortic dissection. Computed tomography showed a primary entry on the ascending aorta and pericardial effusion. Although her hemodynamics was unstable due to cardiac shock, her family wished no open surgery considering her age and frailty. A couple of days later, her condition became stabilized with antihypertensive therapy. Since the dissection was limited within the ascending aorta, closure of the entry with the stentgraft was considered appropriate and much less invasive as compared with an open surgery...

OBJECTIVE: To determine whether left ventricular assist device (LVAD) treatment in children with heart failure would result in the modification of molecular pathways involved in heart failure pathophysiology. STUDY DESIGN: Forty-seven explanted hearts from children were studied (16 nonfailing control, 20 failing, and 11 failing post-LVAD implantation [F-LVAD]). Protein expression and phosphorylation states were determined by receptor binding assays and Western blots...

PURPOSE OF REVIEW: The list of genes associated with systemic inflammatory diseases has been steadily growing because of the explosion of new genomic technologies. Significant advances in the past year have deepened our understanding of the molecular mechanisms linked to inflammation and elucidated insights on the efficacy of specific therapies for these and related conditions. We review the molecular pathogenesis of four recently characterized monogenic autoinflammatory diseases: haploinsufficiency of A20, otulipenia, a severe form of pyrin-associated disease, and a monogenic form of systemic juvenile idiopathic arthritis...

BACKGROUND: In many countries in Asia, the HIV epidemic is in a concentrated phase, with high prevalence in certain risk groups, such as men who inject drugs. There is also a rapid increase of HIV among women. The latter might be due to high levels of sero-discordant couples and increasing transmission from male to female partners over time. METHODS: All adult married patients initiating antiretroviral treatment at four out-patient clinics in Quang Ninh province in north-eastern Vietnam between 2007 and 2009 were asked to participate in the study...

Acute heart failure is still characterized by poor prognosis with high mortality. Diagnosis is based on clinical symptoms and hemodynamic measurements. Early coronary revascularization in cardiogenic shock complicating myocardial infarction improves outcome. The further contemporary therapeutic options in the management of acute heart failure are limited to a merely symptomatic effect with relief of dyspnea, reduction of volume overload and improvement of hemodynamic parameters by vasodilators (in hypertension) or inotropic and vasopressor agents (in hypotension)...

Suicide gene therapy is a promising strategy against melanoma. However, the low efficiency of the gene transfer technique can limit its application. Our preliminary data showed that dioscin, a glucoside saponin, could upregulate the expression of connexins Cx26 and Cx43, major components of gap junctions, in melanoma cells. We hypothesized that dioscin may increase the bystander effect of herpes simplex virus thymidine kinase/ganciclovir (HSV-tk/GCV) through increasing the formation of gap junctions. Further analysis showed that dioscin indeed could increase the gap junctional intercellular communication in B16 melanoma cells, resulting in more efficient GCV-induced bystander killing in B16tk cells...

BACKGROUND: In evidence-based guidelines published in 2000, topiramate was a third-tier migraine preventive with no scientific evidence of efficacy; recommendation for its use reflected consensus opinion and clinical experience. Its neurostabilizing activity, coupled with its favorable weight profile, made topiramate an attractive alternative to other migraine preventives that caused weight gain. When guidelines for migraine prevention in episodic migraine were published in 2012, topiramate was included as a first-line option based on double-blind, randomized controlled trials involving nearly 3000 patients...

INTRODUCTION: Enzalutamide (Xtandi®) is a new potent inhibitor of the signaling pathway for the androgen receptor with a half-life of 5.8 days. It has been on the market for the treatment of metastatic castration-resistant prostate cancer since November 2013. OBJECTIVE: We report the first case of acute generalized exanthematous pustulosis (AGEP) induced by enzalutamide. OBSERVATION: A 62-year-old male patient with no significant medical history, was diagnosed in April 2014 with metastatic prostatic adenocarcinoma...

The primary purpose of the present study was to design and optimize a liposomal formulation of the poorly water-soluble drug oleanolic acid (OA) to improve its oral bioavailability, and prolong the duration of therapeutic drug level. Liposomes containing a soybean lecithin and cholesterol lipid bilayer, a protective hydrophilic polyvinylpyrrolidone-K30 (PVP-K30) coating, and a protective bile salt, sodium deoxycholate, were prepared by a thin-film dispersion method coupled with sonication. Several properties of the PVP-modified OA liposomes (PVPOALs), including surface morphology, particle size, zeta potential and entrapment efficiency were extensively characterized...

PURPOSE: Arginine-glycine-aspartic acid (RGD)-based nanoprobes allow specific imaging of integrin αvβ3, a protein overexpressed during angiogenesis. Therefore, this study applied a novel RGD-coupled, polyacrylic acid (PAA)-coated ultrasmall superparamagnetic iron oxide (USPIO) (referred to as RGD-PAA-USPIO) in order to detect tumor angiogenesis and assess the early response to antiangiogenic treatment in human nasopharyngeal carcinoma (NPC) xenograft model by magnetic resonance imaging (MRI)...

Couples in committed relationships encounter a multitude of issues. According to Metz and McCarthy (2010), when couples report high sexual satisfaction, it accounts for 15-20% of their overall relationship satisfaction. However, when couples report low sexual satisfaction, it contributes 50-70% of their overall satisfaction with their partner. Issues of sexual desire, currently referred to as sexual desire discrepancy, are among the most difficult to treat. Although there are many factors contributing to the issue of sexual desire discrepancy, current literature highlights the importance of emotional intimacy as an outcome and predictor of increased sexual desire...

The haematological abnormalities associated with active pulmonary tuberculosis were known to human beings since decades but Immune Thrombocytopenic Purpura (ITP) secondary to pulmonary tuberculosis have been reported only in a couple of instances. We report a 27 year-old male patient who was admitted to our hospital with fever, shortness of breath, haematuria, epistaxis and generalized petechiae. The sputum positivity for Acid Fast Bacilli (AFB) and chest X-ray reports were suggestive of active pulmonary tuberculosis in our patient...

Small molecule-drug conjugates (SMDCs) are increasingly being considered as an alternative to antibody-drug conjugates (ADCs) for the selective delivery of anticancer agents to the tumor site, sparing normal tissues. Carbonic anhydrase IX (CAIX) is a membrane-bound enzyme, which is over-expressed in the majority of renal cell carcinomas and which can be efficiently targeted in vivo, using charged derivatives of acetazolamide, a small heteroaromatic sulfonamide. Here, we show that SMDC products, obtained by the coupling of acetazolamide with monomethyl auristatin E (MMAE) using dipeptide linkers, display a potent anti-tumoral activity in mice bearing xenografted SKRC-52 renal cell carcinomas...

: In this study, an intelligent drug delivery system was developed by capping doxorubicin (DOX)-loaded hollow mesoporous CuS nanoparticles (HMCuS NPs) with superparamagnetic iron oxide nanoparticles (IONPs). Under near infrared (NIR) light irradiation, the versatile HMCuS NPs could exploit the merits of both photothermal therapy (PTT) and photodynamic therapy (PDT) simultaneously. Herein, the multifunctional IONPs as gatekeeper with the enhanced capping efficiency were supposed to realize "zero premature release" and minimize the adverse side effects during the drug delivery in vivo...

Niemann Pick type C (NPC) disease is a progressive lysosomal storage disorder caused by mutations in genes encoding NPC1/NPC2 proteins, characterized by neurological defects, hepatosplenomegaly and premature death. While the primary biochemical feature of NPC disease is the intracellular accumulation of cholesterol and gangliosides, predominantly in endolysosomes, mitochondrial cholesterol accumulation has also been reported. As accumulation of cholesterol in mitochondria is known to impair the transport of GSH into mitochondria, resulting in mitochondrial GSH (mGSH) depletion, we investigated the impact of mGSH recovery in NPC disease...

Epithelial-mesenchymal transition (EMT) is a phenomenon in cancer progression during which cancer cells undergo remarkable alteration acquiring highly invasive property. The aim of this study was to evaluate specific N-glycan alterations during EMT induced by epidermal growth factor (EGF) in GE11 epithelial cells. Herein, we demonstrated that EGF activated epidermal growth factor receptor (EGFR)/Akt/extracellular signal-regulated kinase (ERK) phosphorylation and promoted GE11 cell proliferation. Meanwhile, EGF stimulated the epithelial cells to undergo morphological alteration, destroying cell-cell inter-contact and exhibiting mesenchymal cells higher metastatic potential...

Issues on the correlation of viral genetic diversity and treatment response to the hepatitis C infection remain uncertain. The bottleneck effect dictates the characteristics of the viral population that will establish the infection in a new host and is related to how the immune system and treatment will be effective against the virus. Here we evaluated the phylogenetic characteristics of quasispecies population and the treatment response pattern of a HCV infected couple. We also analyzed whether the viral population of these patients indicated that they were exposed to the same source for primer infection...

Fluid balance management is of great importance in the critically ill cardiac patient. Although intravenous fluids are a cornerstone therapy in the management of unstable patients, excessive administration coupled with cardiac dysfunction leads to elevation in central venous pressure and end-organ venous congestion. Fluid overload is known to have a detrimental effect on organ function and is responsible for significant morbidity in critically ill patients. Multisystem bedside point of care ultrasound imaging can be used to assess signs of fluid overload and venous congestion in critically ill patients...
