Shaheer Khan, Sameh Mikhail, Joanne Xiu, Mohamed E Salem
Gastroesophageal (GE) malignancies make up a significant and growing segment of newly diagnosed cancers. Approximately 80% of patients who have GE cancers die within 5 years of diagnosis, which means that effective treatments for these malignancies need to be found. Currently, targeted therapies have a minimal role in this disease group. Intensive study of the molecular biology of GE cancers is a relatively new and ongoing venture, but it has already led to a significant increase in our understanding of these malignancies...

BACKGROUND: While neuroendocrine (carcinoid) tumors are increasingly recognized in the adult population, they are often not suspected in children. PROCEDURE: Retrospective review of all well-differentiated neuroendocrine (carcinoid) tumors was performed based on pathology reports from a quaternary pediatric medical center between January 2003 and June 2016. Clinical presentations, treatment approaches, imaging findings, and outcomes were reviewed and analyzed. RESULTS: A total of 45 cases of pathology-proven carcinoid tumor were reported with an average age of 14...

BACKGROUND: Treatment with nab-paclitaxel with gemcitabine demonstrates a survival advantage when compared with single-agent gemcitabine. However, the combination is associated with significant toxicities, leading to a high rate of drug discontinuation. We implemented a modified regimen of gemcitabine and nab-paclitaxel (mGNabP) in an attempt to minimize toxicities while maintaining efficacy. METHODS: A total of 79 evaluable patients with metastatic pancreatic adenocarcinoma (mPC) treated with a modified regimen of gemcitabine (1000 mg/m(2)) and nab-paclitaxel (125 mg/m(2)) on days 1, 15 of every 28-day cycle were identified from our prospective database...

OBJECTIVE: Although rare, pediatric neuroendocrine tumors including carcinoid tumor have increased in incidence over the past few decades. Despite increased recognition, survival rates have not significantly improved. Earlier detection of these tumors is necessary to improve clinical outcomes. This article discusses imaging approaches for detecting pediatric carcinoid tumors including anatomic imaging methods such as CT and MRI as well as functional imaging methods targeting the somatostatin receptor including (111)In-labeled octreotide and newer (68)Ga-based radiotracers that may hold promise in hybrid PET/CT or PET/MRI...

Two different acetylcholinesterase (AChE)-capped mesoporous silica nanoparticles (MSNs), S1-AChE and S2-AChE, were prepared and characterized. MSNs were loaded with rhodamine B and the external surface was functionalized with either pyridostigmine derivative P1 (to yield solid S1) or neostigmine derivative P2 (to obtain S2). The final capped materials were obtained by coordinating grafted P1 or P2 with AChE's active sites (to give S1-AChE and S2-AChE, respectively). Both materials were able to release rhodamine B in the presence of diisopropylfluorophosphate (DFP) or neostigmine in a concentration-dependent manner via the competitive displacement of AChE through DFP and neostigmine coordination with the AChE`s active sites...

INTRODUCTION: Laser in situ keratomelieusis (LASIK) is one of the commonest refractive procedures performed nowadays. The dry eye problem is nearly universal in all patients after LASIK and it can be so annoying that the post-operative patient satisfaction is sometimes precluded. Conventional treatment includes the use of artificial tears. Alternative methods such as punctal plugs and botulinum toxin injection can be used for the management of post-LASIK dry eye. The aim of this study is to compare botulinum toxin injection in the orbicularis muscle to lacrimal punctal plugs for the control of post-LASIK dry eye manifestations...

Studies on the effects of alcohol use on HIV disease progression have been contradictory, with at least one study finding a positive effect of low alcohol consumption on CD4 count. In addition, most such studies have taken place in the developed West. We investigated the association between alcohol use and immune reconstitution through CD4 count response among HIV-infected individuals on antiretroviral therapy (ART) at an urban sub-Saharan African clinic. This was a retrospective cohort study of treatment-naïve HIV-infected adults initiating ART in Nairobi, Kenya and followed for 12 months between January 2009 and December 2012...

The ascidian embryo is an ideal system to investigate how cell position is determined during embryogenesis. Using 3D timelapse imaging and computational methods we analyzed the planar cell divisions in ascidian early embryos and found that spindles in every cell tend to align at metaphase in the long length of the apical surface except in cells undergoing unequal cleavage. Furthermore, the invariant and conserved cleavage pattern of ascidian embryos was found to consist in alternate planar cell divisions between ectoderm and endomesoderm...

BACKGROUND: The prognosis of triple-negative breast cancer (TNBC) is still difficult to establish. Some TNBC benefit from radiotherapy (RT) and are cured, while in other patients metastases appear during the first 3 years after treatment. In this study, an animal model of TNBC was used to determine whether the expression of the cell membrane protease MT1-MMP in cancer cells was associated with radiation-stimulated development of lung metastases. METHODS: Using invasion chambers, irradiated fibroblasts were used as chemoattractants to assess the invasiveness of TNBC D2A1 cell lines showing downregulated expression of MT1-MMP, which were compared with D2A1-wt (wild-type) and D2A1 shMT1-mock (empty vector) cell lines...

Zinc is essential for the activation of approximately 300 metallo-enzymes. Serum and hepatic zinc is decreased in chronic liver disease patients, and zinc depletion has been suggested to accelerate liver fibrosis. The study was designed to assess Zinc status in chronic HCV Egyptian patients and its relationship to fibrosis stage diagnosed by FibroScan. This was a cross-sectional study on 297 Egyptian patients with naïve chronic HCV. All patients underwent laboratory tests (including assessment of serum Zinc) and liver stiffness measurement (LSM) by Transient Elastography (FibroScan(®))...

: The talus is the second most common fractured tarsal bone. While their incidence may be low, talus fractures are severe injuries that can lead to long-term disability and pain. Displaced talar body fractures are typically treated through an open approach with the aim of obtaining anatomic reduction and stable fixation. There are several case reports in the literature demonstrating successful management of talus fractures arthroscopically. An arthroscopic approach minimizes soft tissue trauma, which can help decrease postoperative wound complications and infections...
