The Mig10/RIAM/Lpd (MRL) adapter protein Lpd regulates actin dynamics through interactions with Scar/WAVE and Ena/VASP proteins to promote the formation of cellular protrusions and to stimulate invasive migration. However, the ability of MRL proteins to interact with multiple actin regulators and to promote serum response factor (SRF) signalling has raised the question of whether MRL proteins employ alternative downstream mechanisms to drive oncogenic processes in a context-dependent manner. Here, using a Drosophila model, we show that overexpression of either human Lpd or its Drosophila orthologue Pico can promote growth and invasion of Ras(V12)-induced cell tumours in the brain...

Recently, attention has been focused on methotrexate-induced lymphoproliferative disease (MTX-LPD), and atypical phenotypes are occasionally documented. We encountered two patients with rheumatoid arthritis (RA) who were diagnosed with non-specific LPD (LPD-nos). Biopsy samples were not obtained during the initial examination when the LPD development was discovered, and the patients achieved a complete response after MTX cessation (case 1) or steroid pulse therapy (case 2). However, the tumors flared up 1.5 years later, and LPD-nos was determined following biopsies of the lymph node (LN, case 1) and liver (case 2)...

Epstein-Barr virus (EBV)-associated lymphoproliferative disorders (LPDs) sometimes occur following Anti-thymocyte globulin (ATG) administration for allogenic stem cell transplantation but are rare in aplastic anemia (AA) patients. A 55-year-old woman with AA following ATG developed refractory fever and was diagnosed with EBV-LPD. She was successfully treated with weekly rituximab monotherapy; however, she developed EBV encephalitis. She was admitted to the intensive care unit and finally recovered from unconsciousness...

REVIEW
Hendi Maher, Weiwei Jin, Yiping Mou, Henry Davies
Laparoscopic pancreaticoduodenectomy (LPD) is an extremely challenging surgery. First described in 1994, LPD has been gaining a favorable position in the majority of pancreatic surgery. Now, LPD is worldwide accepted. A literature search was conducted in PubMed, and only papers written in English containing more than 26 publications of LPD were selected. Papers in distal and robotic pancreatic procedure were not included in the review of a total of 222 LPD publications. The total number of patients analyzed was 1,082 from 25 articles and the largest series...

Insall-Salvati (IS) ratio, modified IS ratio (mIS), Caton-Deschamps (CD) index, and Blackburne-Peel (BP) index are patellar height measurements commonly made on lateral radiographs (XRs) in patients with patellofemoral instability. More recently, magnetic resonance imaging (MRI) has been used as an additional imaging modality to measure patellar height. However, different imaging modalities have not been previously compared for all of these measurements. First, to compare the patellar height measurements of IS, mIS, CD, and BP on XR and MRI in first-time lateral patellar dislocation (LPD) patients and a control population and, second, to evaluate for the effect of sex and skeletal maturity...

BACKGROUND This study investigated the protective effects of pharmaceutical CD26/dipeptidylpeptidase-4 (CD26/DPP-4) inhibitor in lung transplantation (LTx). Changes in protein expression associated with the treatment were screened and identified to evaluate the role of kininogen-1 in early-term ischemia/reperfusion (I/R) injury after LTx. MATERIAL AND METHODS Orthotopic single LTx was performed in syngeneic C57BL/6 mice, with a pharmaceutical CD26/DPP-4 inhibitor (vildagliptin, subcutaneous injection, 10 mg/kg, every 12 h) administered to the investigational group...

Emerging studies revealed that maternal protein restriction was associated with increased risk of type 2 diabetes mellitus in adulthood. However, the mechanisms of its effects on offspring, especially during early life of offspring, are poorly understood. Here, it is hypothesized that impaired metabolic health in offspring from maternal low-protein diet (LPD) is associated with perturbed miRNAs expression in offspring as early as the weaning age. We examined the metabolic effects on the C57BL/6J mice male offspring at weaning from dams fed with LPD or normal chow diet (NCD) throughout pregnancy and lactation...

BACKGROUND: Dietary salts are important factors in metabolic disorders. They are vital components of enzymes, vitamins, hormones, and signal transduction that act synergistically to regulate lipid metabolism. Our previous studies have identified that Krüppel-like factor -3 (KLF-3) is an essential regulator of lipid metabolism. However, it is not known if KLF-2 also regulates lipid metabolism and whether KLF-2 and -3 mediate the effects of dietary salts on lipid metabolism. METHODS: In this study, we used klf mutants [homozygous klf-2 (ok1043) V and klf-3 (ok1975) II mutants] to investigate the role of dietary salts in lipid metabolism...

Phosphoinositides play pivotal roles in the regulation of cancer cell phenotypes. Among them, phosphatidylinositol 3,4-bisphosphate (PI(3,4)P2 ) localizes to the invadopodia, and positively regulates tumor cell invasion. In this study, we examined the effect of PI(3,4)P2 on focal adhesion dynamics in MDA-MB-231 basal breast cancer cells. Knockdown of SHIP2, a phosphatidylinositol 3,4,5-trisphosphatase (PIP3 ) 5-phosphatase that generates PI(3,4)P2 , in MDA-MB-231 breast cancer cells, induced the development of focal adhesions and cell spreading, leading to the suppression of invasion...

BACKGROUND: Postural instability may result from altered sequencing of automatic motor programs for anticipatory postural corrections and/or impaired motor learning in Parkinson Disease (PD) patients. Comorbid white matter disease is a major determinant of axial motor impairment, leading to poorer stability than nigrostriatal dopaminergic denervation per se. OBJECTIVE: To assess differences in anticipatory control of postural stability function between subjects affected by PD with comorbid leukoaraiosis (LPD), idiopathic Parkinson disease (IPD) and elderly health subjects (EHS) as control group...

The growth characteristics of Listeria monocytogenes inoculated onto frozen foods (corn, green peas, crabmeat, and shrimp) and thawed by being stored at 4, 8, 12, and 20°C were investigated. The growth parameters, lag-phase duration (LPD) and exponential growth rate (EGR), were determined by using a two-phase linear growth model as a primary model and a square root model for EGR and a quadratic model for LPD as secondary models, based on the growth data. The EGR model predictions were compared with growth rates obtained from the USDA Pathogen Modeling Program, calculated with similar pH, salt percentage, and NaNO2 parameters, at all storage temperatures...

BACKGROUND: Introduced more than 20 years ago, laparoscopic pancreatic surgery (LAPS) has not reached a uniform acceptance among HPB surgeons. As a result, there is no consensus regarding its use in patients with pancreatic neoplasms. This study, organized by the European Association for Endoscopic Surgery (EAES), aimed to develop consensus statements and clinical recommendations on the application of LAPS in these patients. METHODS: An international panel of experts was selected based on their clinical and scientific expertise in laparoscopic and open pancreatic surgery...

BACKGROUND: Epstein-Barr Virus (EBV) is a widely disseminated lymphotropic herpes virus implicated in benign and malignant disorders. In transplant patients, immunosuppressive drugs (cyclosporine) diminish control of EBV replication, potentially leading to lymphoproliferative disorders (LPD). Rheumatoid arthritis (RA) patients have impaired control of EBV infection and have EBV load ten times higher than controls. As post transplant patients, patients with RA have increased risk of developing lymphomas...

A 13-year-old boy was admitted to our hospital because of persistent diarrhea, abdominal pain, and bloody stools. The patient had experienced repeated hospitalizations for the treatment of respiratory infections since early childhood. Colonoscopic and pathological studies led to a diagnosis of gut-associated T-cell lymphoproliferative disease (T-cell LPD). Laboratory data showed T-lymphocytopenia (492/µl), increased serum IgG levels (1,984 mg/dl), and low serum antibody titers for specific pathogens. Combined immunodeficiency accompanied by T-LPD suggested the diagnosis of activated PI3Kδ syndrome (APDS)...

Cutaneous T cell lymphomas (CTCLs) are heterogeneous, with a prognosis determined in large part by combined clinical, histopathologic, and immunophenotypic features. They are classified under the WHO-EORTC classification of primary cutaneous lymphoma. Whether or not a patient diagnosed with CTCL will experience an aggressive course may not be completely predictable; however, certain subtypes have been proven to be associated with a poor response to therapy and/or short survival. These aggressive subtypes may be diagnosed by certain histologic, immunophenotypic, and clinical features; however, there are benign lymphoproliferative disorders (LPD), such as lymphomatoid papulosis (LyP) that present with biopsy findings that simulate an aggressive lymphoma...
