In order to achieve prolong corneal contact time of norfloxacin(NFX) for treatment of extra ocular diseases, a pH triggered nanoparticulate in situ gelling system was designed to explore dual advantage of nanoparticles and in situ gelling system, for its ocular delivery. NFX loaded nanocarriers were developed by ionotropic gelation technique using chitosan as a matrix forming polymer, cross-lin...

Introduction: Virtual bronchoscopy is a reliable and efficient diagnostic method for primary symptoms of lung cancer. The segmentation of airways from CT images is a critical step for numerous virtual bronchoscopy applications. Materials and Methods: To overcome the limitations of the fuzzy connectedness method, the proposed technique, called fuzzy connectivity - fuzzy C-mean (FC-FCM), utilized...

Quorum sensing (QS) has been extensively studied in pure stains of microorganisms, but the ecological roles QS multi-species microbial aggregates are poorly understood due to aggregates’ heterogeneity and complexity, particular phosphorus (P) entrapment, a key aspect element cycling. Using periphytic biofilm as microbial-aggregate model, we addressed how signaling via N-acyl-homoserine-lactones...

Recent evidence has suggested that the presence and proliferation of vasa vasorum (VV) in the plaque is correlated to an increase in plaque inflammation and destabilization, leading to acute coronary events (e.g., heart attacks). Therefore, the detection and quantification of VV in plaque (i.e., extra luminal blood perfusion) is an important problem since it may enable the development of an ind...

Primary windpipe tumour is extremely rare. Squamous cell carcinoma is the most common malignant form, especially in smokers. The radiological appearance of these neoplasms can be classified as intra-luminal, wall-thickening, exophytic form; the majority of the lesions are obstructive in nature and then tend to extra-luminal invasion. This tumour is usually diagnosed late on account of delayed s...

INTRODUCTION We present a case of an extra-luminal haematoma following routine colonoscopy. This case highlights an uncommon but potentially life threatening complication in which there is little published literature to date. PRESENTATION OF CASE A 73 year old male presented with abdominal pain and a reduction in haemoglobin following an uneventful colonoscopy. The imaging had been required a...

femoropopliteal bypass graft from the groin to the knee to save the lower extremities of patients that have severe arterial disease. The most common cause of early failure of a femoropopliteal bypass graft is usually technical error. Sometimes, extrinsic compression by surrounding structures may result in impediment of blood flow within the graft (1). The femoropopliteal bypass graft can be ent...
