Evaluation of the antileukemic effects of neurokinin-1 receptor antagonists, aprepitant, and L-733,060, in chronic and acute myeloid leukemic cells.

Neurokinin-1 receptor (NK1R) antagonists are known for their anxiolytic, antiemetic, anticancer, and anti-inflammatory effects. Aprepitant is used in vomiting and nausea, which are the most common side-effects of patients undergoing chemotherapy for cancer. L-733,060 has been shown to have anxiolytic and antidepressant effects in animal studies and anticancer effect in in-vitro studies. Previous anticancer activity studies with NK1R antagonists have reported that NK-1 antagonists have an antitumoral activit...

Andrographolide sensitizes Hep-2 human laryngeal cancer cells to carboplatin-induced apoptosis by increasing reactive oxygen species levels.

Andrographolide is a natural diterpenoid from Andrographis paniculata that has been proposed as an anticancer agent as well as a chemosensitizer for use in combination with anticancer drugs. Carboplatin is the first-line chemotherapeutic agent for advanced laryngeal carcinoma. However, the clinical efficacy of carboplatin is limited by drug resistance and side effects. The aim of this study was to investigate whether andrographolide has a synergistic antitumor effect with carboplatin on human laryngeal canc...

Incidental Finding of Acute Lymphocytic Leukemia in a Prostate-Specific Membrane Antigen PET/CT.

PSMA PET/CT is known to show uptake in various benign and malignant processes. The following PSMA PET/CT was performed for prostate carcinoma staging (Gleason 3 + 4 left apex; PSA 5.8). It shows incidental diffuse PSMA marrow uptake, not typical for prostate metastatic disease. No treatment had been commenced at the time of the scan. Serology and bone marrow biopsy showed B-cell acute lymphocytic leukemia. Focal PSMA uptake in the right ischium was correlated with a T1 hypointense lesion on a previous MRI a...

68Ga-DOTATATE Uptake in Pancreatic Metastasis of Renal Cell Carcinoma Mimicking Pancreatic Neuroendocrine Tumor.

A 61-year-old man, with a history of prior clear cell renal cell carcinoma in remission, was referred to Ga-DOTATATE PET/CT for the further evaluation of pancreatic tail mass. Ga-DOTATATE PET/CT showed pathologically intense uptake on the pancreatic mass; subsequent biopsy of the pancreatic mass confirmed the diagnosis of clear cell renal cell carcinoma metastasis. Ga-DOTATATE uptake is not specific for neuroendocrine tumors. In the presence of prior malignancy, it should be kept in mind that malignancies a...

Prognostic Value of Pretreatment Radiomic Features of 18F-FDG PET in Patients With Hodgkin Lymphoma.

This study investigated whether a radiomic analysis of pretreatment F-FDG PET can predict prognosis in patients with Hodgkin lymphoma (HL).

Heat-Damaged Red Blood Cell Scintigraphy in Helping Interpretation of 68Ga-DOTTATE PET/CT.

Ga-DOTATATE PET/CT was performed to determine the cause of endogenous Cushing syndrome in a 10-year-old boy whose MRI studies did not reveal pituitary or adrenal gland abnormality. The PET/CT images demonstrated an intense activity in a small soft tissue nodule in the left upper abdomen where splenules are commonly located. Heat-damaged Tc-labeled red blood cell imaging showed that this soft tissue nodule did not have increased red blood cell activity, which indicated that this lesion was a true somatostati...

Incidental Finding of Benign Trichilemmal Cysts on 99mTc-Octreotide Scan.

A 63-year-old woman with neuroendocrine carcinoma of the colon was referred to our department for staging with Tc-octreotide scan. Two focal, highly intense, superficial lesions were detected in patient's scalp and paralumbar region, medial to the right kidney. Pathology correlation was recommended, revealing them both to be benign trichilemmal cysts. This unexpected finding strengthens the hypothesis of Merkel cell carcinoma and trichilemmal cysts originating from pluripotent stem cells of adnexal epitheli...

Comparison of outcomes after human leukocyte antigen-matched and haploidentical hematopoietic stem-cell transplantation for multiple myeloma.

Allogeneic stem-cell transplantation (SCT) is a well-established immunotherapeutic strategy for multiple myeloma (MM) with a potent and often sustained graft-vs.-myeloma effect. This multicenter investigation aimed to analyze the complications and survival of haploidentical SCT in patients with MM, and compare the main outcomes with matched-related donors (MRDs).

Surgical complexity and prognostic outcome of small volume renal cell carcinoma with high-level venous tumor thrombus and large volume renal cell carcinoma with low-level thrombus.

Radical nephrectomy with thrombectomy is one of the most difficult and complicated urological operations. But the roles of renal tumor volume and thrombus level in surgical complexity and prognostic outcome are not clear. This study aimed to evaluate the surgical complexity and prognostic outcome between the volume of renal cell carcinoma (RCC) and the level of venous tumor thrombus.

Resistance Exercise-induced Changes in Muscle Metabolism are Load-dependent.

Lower-load (LL), higher-repetition resistance exercise training (RET) can increase muscle mass similar degree as higher-load (HL), lower-repetition RET. However, little is known about how LL and HL RET modulate other aspects of the RET phenotype such as satellite cells, myonuclei, and mitochondrial proteins. We aimed to investigate changes in muscle mass, muscle strength, satellite cell activity, myonuclear addition, and mitochondrial protein content following prolonged RET with LL and HL RET.

The Successful Sequential Use of Plerixafor and Eltrombopag For Hematopoietic Cell Transplantation in a Child With High-Risk Neuroblastoma.

High-dose chemotherapy with autologous hematopoietic stem cell transplantation improves event-free survival in patients with high-risk neuroblastoma. However, in heavily pretreated patients, poor marrow function can be an obstacle in the successful proceeding of therapy. Priming with plerixafor plus filgrastim is an option for effective mobilization and collection of stem cells. In addition, thrombopoietin agonist eltrombopag can improve the outcome of posttransplantation thrombocytopenia and poor graft fun...

How to Treat Cytomegalovirus-induced Hemophagocytic Lymphohistiocytosis in a Child With Leukemia.

Hemophagocytic lymphohistiocytosis (HLH) is a syndrome characterized by a hyperinflammatory state due to an aberrant activation of the immune cells. It can be familial or secondary to malignancy, autoimmune or metabolic diseases. Most HLH cases are triggered by infection. Histiocyte society suggested HLH-2004 protocol for diagnosis and treatment of both forms. Here, we present a three-year-old girl with B-cell acute lymphoblastic leukemia who developed HLH secondary to cytomegalovirus infection during maint...

X-Linked IRAK1 Polymorphism is Associated with Sex-Related Differences In Polymorphonuclear Granulocyte and Monocyte Activation and Response Variabilities.

Common X-linked genetic polymorphisms are expected to alter cellular responses affecting males and females differently through sex-linked inheritance pattern as well as X chromosome (ChrX) mosaicism and associated ChrX skewing, which is unique to females. We tested this hypothesis in ex vivo lipopolysaccharide and phorbol ester-stimulated polymorphonuclear granulocytes (PMNs) and monocytes from healthy volunteers (n = 51). Observations were analyzed after stratification by sex alone or the presence of v...

A gene co-expression network-based analysis of multiple brain tissues reveals novel genes and molecular pathways underlying major depression.

Major depression is a common and severe psychiatric disorder with a highly polygenic genetic architecture. Genome-wide association studies have successfully identified multiple independent genetic loci that harbour variants associated with major depression, but the exact causal genes and biological mechanisms are largely unknown. Tissue-specific network approaches may identify molecular mechanisms underlying major depression and provide a biological substrate for integrative analyses. We provide a framework...

Attenuation of chronic antiviral T-cell responses through constitutive COX2-dependent prostanoid synthesis by lymph node fibroblasts.

Lymphoid T-zone fibroblastic reticular cells (FRCs) actively promote T-cell trafficking, homeostasis, and expansion but can also attenuate excessive T-cell responses via inducible nitric oxide (NO) and constitutive prostanoid release. It remains unclear how these FRC-derived mediators dampen T-cell responses and whether this occurs in vivo. Here, we confirm that murine lymph node (LN) FRCs produce prostaglandin E2 (PGE2) in a cyclooxygenase-2 (COX2)-dependent and inflammation-independent fashion. We show th...

Molecular dissection of the oncogenic role of ETS1 in the mesenchymal subtypes of head and neck squamous cell carcinoma.

Head and Neck Squamous Cell Carcinoma (HNSCC) is a heterogeneous disease of significant mortality and with limited treatment options. Recent genomic analysis of HNSCC tumors has identified several distinct molecular classes, of which the mesenchymal subtype is associated with Epithelial to Mesenchymal Transition (EMT) and shown to correlate with poor survival and drug resistance. Here, we utilize an integrated approach to characterize the molecular function of ETS1, an oncogenic transcription factor specifi...

Mesenchymal stromal cells contract collagen more efficiently than dermal fibroblasts: Implications for cytotherapy.

Stem cell therapy is the next generation a well-established technique. Cell therapy with mesenchymal stem cells (MSC) has been demonstrated to enhance wound healing in diabetic mice, at least partly due to improved growth factor production. However, it is unclear whether MSC can biomechanically affect wound closure. Utilizing the well-established cell-populated collagen gel contraction model we investigated the interactions between MSC and the extracellular matrix.

This study investigated the effects of hydroxyurea (HU) on hematological, biochemical and inflammatory parameters in children with sickle cell anemia (SCA) in association with βS haplotype and α-thalassemia. We included 22 children with SCA who were followed for an average of 14.5 months. Laboratory parameters were assessed by electronic methods, and molecular analysis was investigated by PCR-RFLP and allele-specific PCR. Results showed significant increases in hemoglobin, HbF, hematocrit, MCV, MCH, gluco...

A nationwide survey of Leishmania infantum infection in cats and associated risk factors in Italy.

Though scantly investigated, Leishmania infantum infection and clinical cases of leishmaniosis in cats have been recently reported in several countries of the Mediterranean basin, with large variability in prevalence data. A major limitation in the comparability of the data available is attributed to the differences in diagnostic techniques employed and cat populations sampled. The aim of this study was to assess the prevalence of L. infantum infection in owned cats across Italy by serological and molecular...

Reservoir computing model of prefrontal cortex creates novel combinations of previous navigation sequences from hippocampal place-cell replay with spatial reward propagation.

As rats learn to search for multiple sources of food or water in a complex environment, they generate increasingly efficient trajectories between reward sites. Such spatial navigation capacity involves the replay of hippocampal place-cells during awake states, generating small sequences of spatially related place-cell activity that we call "snippets". These snippets occur primarily during sharp-wave-ripples (SWRs). Here we focus on the role of such replay events, as the animal is learning a traveling salesp...

Inhibition of Polo-like kinase 2 ameliorates pathogenesis in Alzheimer's disease model mice.

Alzheimer disease (AD) is a neurodegenerative disorder characterized by pathological hallmarks of neurofibrillary tangles and amyloid plaques. The plaques are formed by aggregation and accumulation of amyloid β (Aβ), a cleavage fragment of amyloid precursor protein (APP). Enhanced neuronal activity and seizure events are frequently observed in AD, and elevated synaptic activity promotes Aβ production. However, the mechanisms that link synaptic hyperactivity to APP processing and AD pathogenesis are not w...

Combination of red blood cell distribution width and body mass index (COR-BMI) predicts in-hospital mortality in patients with different diagnoses?

The combination of red blood cell distribution width and body mass index (COR-BMI) is indicated as a new prognostic index of survival in patients with laryngeal cancer. However, the ability of this prediction in other types of cancer or whether its use can be expanded to non-oncological patients is unknown. The aim of this study was to investigate the prediction of prognosis of in-hospital mortality of the COR-BMI in oncological and non-oncological patients.

Histone Methyltransferase SETDB1 Promotes Colorectal Cancer Proliferation through the STAT1-CCND1/CDK6 Axis.

Upregulation of histone methyltransferase SETDB1 is associated with poor prognosis in cancer patients. However, the mechanism of oncogenicity of SETDB1 in cancer is hitherto unknown. Here, we show that SETDB1 is upregulated in human colorectal cancer (CRC) where its level correlates with poor clinical outcome. Ectopic SETDB1 promotes CRC cell proliferation, whereas SETDB1 attenuation inhibits this process. Flow cytometry reveals that SETDB1 promotes proliferation by driving the CRC cell cycle from G0/G1 pha...

Novel type of sub-retinal pigment shield in the miniaturized compound eye of Trichogramma evanescens.

Pigment granules, found in different cell types of the retina in insect compound eyes, fulfill important functions. They isolate the individual ommatidia from stray light, regulate the angular sensitivity and restrict the light that reaches the photoreceptor according to ambient light intensities. Descriptions of pigment cells within the retina are included in ultrastructural eye descriptions, but knowledge of pigment cell types beneath the retina and basal matrix (BM) are relatively limited in insects. In ...
