The emergence of nanotechnology has opened new horizons for constructing efficient recognition interfaces. This is the first report where the potential of a multiwalled carbon nanotube based zinc nanocomposite (MWCNTs-Zn NPs) investigated for the detection of an agricultural pathogen i.e. Chili leaf curl betasatellite (ChLCB). Atomic force microscope analyses revealed the presence of multiwalled carbon nanotubes (MWCNTs) having a diameter of 50-100nm with zinc nanoparticles (Zn-NPs) of 25-500nm. In this system, these bunches of Zn-NPs anchored along the whole lengths of MWCNTs were used for the immobilization of probe DNA strands...

BACKGROUND: The majority of iliac venous obstructions occur on the left side, and endovascular therapy has become the first line treatment for this condition. A left common iliac venous stent will protrude into the inferior vena cava (IVC) to some extent, thereby covering the contralateral common iliac vein (CIV) outflow. This may increase the risk of thrombosis of the contralateral iliac vein. The aim of this paper was to determine the rate of, and factors associated with, contralateral lower limb venous thrombosis after stenting, and to evaluate the results of salvage revascularisation...

Sumary The identification of a escrotal mass without pain or report of trauma should be investigated to rule out scrotal cancer. We report the case of a young Brazilian boy who underwent orchiectomy after magnetic resonance imaging (MRI) and duplex scan (DS) indicating a high possibility of cancer. Blood exams ruled out the possibility of cancer. Testicular biopsy was not indicated. After surgery the diagnostic was extensive orchiepididymitis by Schistosoma. In endemic areas orchiepididymis by Schistosoma should be investigate to avoid unnecessary surgeries...

INTRODUCTION: Selection of the optimal anastomosis site is essential for obtaining good results from distal bypass. Herein, a unique, precise technique that uses pre-operative duplex scanning for selecting this site is presented. TECHNICAL SUMMARY: Before distal bypass surgery, duplex scanning is performed to assess patency and flow. Use of the venous preset mode and controlling the slant function allows visualisation of colour Doppler flow inside the arteries, thus enabling selection of the best segment for anastomosis...

BACKGROUND: Tumor embolisms (TE) are an underappreciated source of pulmonary embolisms in sarcoma. Most evidence in the literature is limited to case reports and none have described the presence of TE secondary to myxofibrosarcoma. We report the first case of myxofibrosarcoma TE and perform a review of the literature for TE secondary to bone and soft tissue sarcomas (STS). CASE PRESENTATION: A 36-year-old female presented with debilitating pain of the right upper extremity secondary to a recurrent soft tissue sarcoma...

In this case report, we describe an unusual episode of bilateral submassive pulmonary embolism (PE) caused by a popliteal vein aneurysm (PVA). The development of PE stems from many risk factors including obesity (BMI³ 30 kg/m2), hypertension, cigarette smoking (greater than 25 cigarettes per day), increasing age, surgery, immobility, malignancy, and inherited thrombophilia. A PVA is a rare but significant cause of PE. A 28-year-old male presented to the emergency department with progressive shortness of breath...

BACKGROUND: The first-line recommendation for treatment of acute iliofemoral deep vein thrombosis (IFDVT) is catheter-directed or pharmaco-mechanical thrombolysis (CDT/PCDT). Recent analysis of surgical thrombectomy has shown comparable results. However this procedure is not commonly given as much importance as interventional techniques. We analyzed patient outcome of surgical thrombectomy using modern endovascular techniques in both the short and long term. METHODS: All consecutive patients who underwent surgical thrombectomy at our institution between April 2008 and April 2017 were included...

BACKGROUND: Wandering spleen is a rare clinical entity caused by absence of the spleen's peritoneal attachments, allowing the spleen to move freely within the peritoneal cavity [1]. This disease is most commonly seen in children and young women [1, 2]. Affected individuals are predisposed to complications including splenic torsion, splenic infarction, and pancreatic necrosis [3, 4]. Patients may present with constipation, an abdominal mass, swelling, or acute abdominal pain if splenic torsion has occurred [4]...

Popliteal artery entrapment syndrome (PAES) is a recognised cause of lower limb peripheral arterial disease in young adults. We describe the cases of two otherwise healthy brothers who presented with the condition 5 years apart. The first brother, who is also the first author of this case report, presented aged 19 with worsening, right-sided, exercise-induced lower leg pain and transient foot pallor. Imaging confirmed PAES and irreversible localised arterial damage. Surgery was performed to release the entrapment and resect the section of diseased artery...
