leishmaniasis include several clinical manifestations, mostly cutaneous, visceral and mucosal (1, 2). various species can lead to diverse clinical presentations. thus species identification contribute to proper management (3). localized leishmania lymphadenitis (lll) is a distinct entity in clinicopathologic field presenting with isolated lymphadenitis and possible cocomitant cutaneous lesion i...

abstract castleman disease or giant node hyperplasia is a rare disorder of the lymphoid tissue most often involving the mediastinal lymph nodes. we report a case of localized retroperitoneal hyaline-vascular type of castleman disease. a 35-year old woman presented with mild epigastric pain with radiation to the back. amild anemia was the only abnormal associated finding. abdominal ultrasound an...

249 enteropathogenic Escherichia coli (EPEC) strains from faecal samples of 90 children with diarrhoea were examined for verotoxin (VT) production. Polymyxin B extracts of 61 strains belonging to 9 serogroups from 35 children produced various verotoxins (VTs). The titre of these various VTs ranged from I :40 to I: 12HO. Of the 26 (43.6%) adherent strains, 19 (73%) exhibited localized adhere...

Background: Esophageal Atresia and Tracheo-Esophageal Fistula (EA/TEF) occurs sporadically and its etiology is poorly understood. We observed six cases of EA/TEF within three weeks of October 2007 at the Lagos University Teaching Hospital (LUTH), Nigeria. Aims: To analyze the monthly trends of presentation of EA/TEF at the LUTH from 2002-7, test the hypothesis that the October figures were not ...

Adhesion of spider web anchorages has been studied in recent years, including the specific functionalities achieved through different architectures. To better understand the delamination mechanisms of these and other biological or artificial fibrillar adhesives, and how their adhesion can be optimized, we develop a novel numerical model to simulate the multiple peeling of structures with arbitr...

Plasmonic structures couple oscillating electromagnetic fields to conduction electrons in noble metals and thereby can confine optical-frequency excitations at nanometre scales. This confinement both facilitates miniaturization of nanophotonic devices and makes their response highly sensitive to mechanical motion. Mechanically coupled plasmonic devices thus hold great promise as building blocks...

The ever-increasing computation complexity of fast-growing Deep Neural Networks (DNNs) has requested new computing paradigms to overcome the memory wall in conventional Von Neumann architectures. emerging Computing-In-Memory (CIM) architecture been a promising candidate accelerate neural network computing. However, data movement between CIM arrays may still dominate total power consumption desi...

Energy is one of the most critical constraints for sensor network applications. In this paper, we exploit the localized prediction paradigm for power-efficient object tracking sensor network. Localized prediction consists of a localized network architecture and a prediction mechanism called dual prediction, which achieve power savings by allowing most of the sensor nodes stay in sleep mode and ...
