Indolent T-lymphoblastic proliferation (iT-LBP) is a non-clonal benign condition showing extrathymic proliferation of T-lymphoblasts positive for CD3, CD4, CD8, and TdT. Isolated iT-LBP has been observed, but the majority of iT-LBP have been seen in conjunction with other disorders including Castleman disease, hepatocellular carcinoma, follicular dendritic cell tumors, angioimmunoblastic T-cell lymphoma, myasthenia gravis, and acinic cell carcinoma (ACC). The clinical course of iT-LBP is indolent, and no therapy is usually required...

Iron overload is inevitable in patients who are transfusion dependent. In young children with transfusion-dependent thalassemia (TDT), current practice is to delay the start of iron chelation therapy due to concerns over toxicities, which have been observed when deferoxamine was started too early. However, doing so may increase the risk of iron accumulation that will be manifested as toxicities later in life. This study investigated whether deferiprone, a chelator with a lower affinity for iron than deferoxamine, could postpone transfusional iron overload while maintaining a good safety profile...

Isolated MYC rearrangement without other recurrent genetic abnormalities is rare in B lymphoblastic leukemia/lymphoma (B-ALL/LBL), with most cases reported in pediatric patients. We report 3 adult cases with lymphoblasts showing a precursor B cell immunophenotype, and isolated MYC/IGH translocation. All 3 cases occurred in male patients with initial presentation of diffuse lymphadenopathy. Cases 1 and 2 had B-ALL with significantly increased lymphoblasts in peripheral blood and bone marrow. Case 3, a patient with human immunodeficiency virus infection, had the diagnosis of B-LBL made on a retroperitoneal lymph node biopsy and had no peripheral blood or bone marrow involvement...

FGFR1 translocation may cause myeloid or lymphoid neoplasm but rarely systemic mastocytosis (SM). Conversely, SM is associated with myeloproliferative neoplasm (MPN), but rarely lymphoblastic lymphoma (LBL) or FGFR1 translocation. We report the first case of FGFR1 translocation in a patient with concurrent LBL, MPN, and SM. A 21-year-old male patient presented with diffuse lymphadenopathies and leukocytosis. TdT(+)/cytoCD3(+)/CD79a(weakly+) LBL was identified in the lymph node. Bone marrow had MPN, SM, and TdT(+)/CD79a(+)/cytoCD3(weakly+) LBL...

BACKGROUND: Phantom limb pain (PLP) affects a high percentage of amputees. Since treatment options are limited, low quality of life and addiction to pain medication is frequent. New attempts, such as mirror therapy or electrical sensory discrimination training, make use of the brain's plasticity to alleviate this centrally derived pain. AIM: This pilot study assessed the question, whether home-based tactile discrimination training (TDT) leads to a stronger decrease in phantom limb pain levels, compared to a standard massage treatment...

Electrochemiluminescence (ECL) with high sensitivity and excellent controllability provides a promising approach for ultrasensitive detection of multiple biomarkers. However, the detection for multiple types of biomarkers on a single interface remains considerable challenge owing to the functional differentiation of different types of biomarkers. Herein, we utilized "on-off-on" switching, target-induced cleavage of peptide, and TdT (terminal deoxynucleoside transferase)-mediated extension successfully constructing a novel ECL biosensor for the ultrasensitive detection of microRNA-141 (miRNA-141) and matrix metalloproteinase-2 (MMP-2)...

DNA methyltransferases (MTases) may specifically recognize the short palindromic sequences and transfer a methyl group from S-adenosyl-l-methionine to target cytosine/adenine. The aberrant DNA methylation is linked to the abnormal DNA MTase activity, and some DNA MTases have become promising targets of anticancer/antimicrobial drugs. However, the reported DNA MTase assays often involve laborious operation, expensive instruments, and radio-labeled substrates. Here, we develop a simple and label-free fluorescent method to sensitively detect DNA adenine methyltransferase (Dam) on the basis of terminal deoxynucleotidyl transferase (TdT)-activated Endonuclease IV (Endo IV)-assisted hyperbranched amplification...

Myeloid sarcoma is a tumor mass of immature myeloid or granulocytic cells that affects extramedullary anatomic sites, including uncommonly the oral cavity. A 24-year-old female was referred for evaluation of a fast growing painful gingival swelling lasting 2 weeks, associated with fever, fatigue, and cervical lymphadenopathy. Intraoral examination showed a bluish swelling on the right posterior lower gingiva exhibiting necrotic surface. Incisional biopsy of the gingival lesion displayed diffuse infiltration of undifferentiated tumor cells with granulocytic appearance, strongly immunopositive for CD99, myeloperoxidase and Ki-67 (60%), and negative for CD20, CD3, CD34 and TdT...

BACKGROUND/AIM: Strabismus is a common condition with misalignment between two eyes that may lead to decrease of visual acuity, lack of binocularity, and diplopia. It is caused by heterogeneous environmental and genetic risk factors. Our previous research has identified new chromosomal susceptibility loci in 4q28.3 and 7q31.2 regions for comitant strabismus in Japanese families. We conducted a verification study by linkage analysis to narrow the chromosomal loci down to a single gene...

This work reports oligothiophene-functionalized truxene-based stationary phases (TTT, TDT and TFT) with a unique star-shaped π-conjugated architecture for gas chromatographic (GC) separations. They exhibited medium polarity and column efficiency of 3340-3760 plates/m determined by naphthalene at 120°C. Among them, the TTT stationary phase displayed advantageous resolving capability over the TDT and TFT phases for a wide ranging analytes from apolar to polar, particularly for structural and positional isomers, including alcohols, phenols, halogenated and alkylated benzenes and naphthalenes...

Yinan Wang, Choiwan Lau, Jianzhong Lu
Herein we exploited a novel target-initiated labeling strategy for the multiplex detection of microRNAs (miRNAs) by coupling duplex-specific nuclease (DSN) with terminal deoxynucleotidyl transferase (TdT). In the presence of target miRNA, the immobilized and 3'-blocked capture probes hybridized with target and thus the formed DNA-RNA hybrid was recognized by DSN. DSN mediated the digestion of 3'-phosphated capture probes (CPs) in the hybrids and synchronously target was released and recycled for another round of hybridization and cleavage...

High levels of reactive oxygen species (ROS) contribute to muscle cell death in aging and disuse. We have previously found that resveratrol can reduce oxidative stress in response to aging and hindlimb unloading in rodents in vivo, but it was not known if resveratrol would protect muscle stem cells during repair or regeneration when oxidative stress is high. To test the protective role of resveratrol on muscle stem cells directly, we treated the C2C12 mouse myoblast cell line with moderate (100 μM) or very high (1 mM) levels of H2O2 in the presence or absence of resveratrol...

INTRODUCTION: Avascular necrosis of the head of femur (AVNF) has frequently been reported with sickle cell anemia but is not commonly associated with beta thalassemia. CASE REPORT: We report a case of 14-year-old male with transfusion-dependent thalassemia (TDT) and hepatitis C, who developed bilateral atraumatic AVNF requiring surgical correction. The likely etiopathogenesis and the review of literature for this uncommon finding are discussed. CONCLUSION: AVNF should be considered as a possibility in a patient with TDT presenting with hip pain...

Motivation: Inappropriate disclosure of human genomes may put the privacy of study subjects and of their family members at risk. Existing privacy-preserving mechanisms for Genome-Wide Association Studies (GWAS) mainly focus on protecting individual information in case-control studies. Protecting privacy in family-based studies is more difficult. The transmission disequilibrium test (TDT) is a powerful family-based association test employed in many rare disease studies. It gathers information about families (most frequently involving parents, affected children and their siblings)...

Though piperazine derivative BK10007S was known to induce apoptosis in pancreatic cancer xenograft model as a T-type CaV3.1 a1G isoform calcium channel blocker, its underlying antitumor mechanism still remains unclear so far. Thus, in the present study, the antitumor mechanism of BK10007S was elucidated in hepatocellular carcinoma cells (HCCs). Herein, BK10007S showed significant cytotoxicity by 3-[4,5-2-yl]-2,5-diphenyltetra-zolium bromide (MTT) assay and anti-proliferative effects by colony formation assay in HepG2 and SK-Hep1 cells...
