Facile hydrothermal synthesis of BiVO nanomaterials for degradation of industrial waste.

Bismuth Vanadate (BiVO) has been synthesized using simple hydrothermal technique while varying the pH of concentrated HSO. With the increase of pH values (from 06 to 10), the morphology of the synthesized material tuned in the form of nano-spheres and cubes in the range from 50 to 60 nm. The lateral affect tuned the bandgap of BiVO from 2.

Fabrication of novel BiVO/BiOheterostructure with superior visible light induced photocatalytic properties.

Heterostructure BiVO/BiOnanocomposites with enhanced visible light activity are effectively synthesized through an easiest and single step hydrothermal route, using bismuth subnitrate and ammonium meta-vanadate as main raw materials in existence of citric acid. The phase and surface structure, topography and optical properties of synthesized composites are characterized by XRD, SEM, EDX, FTIR, UV-Visible and PL spectroscopy. It was found that 5%BiVO/BiO(BOBV-5) nanocomposite exhibit excellent photocatalytic performance for rhodamine B dye degradation and tetracyclic under irradiation of visible light as compared to single component i.

Efficient biosensing through 1D silver nanostructured devices using plasmonic effect.

The current work explores the excitation of surface plasmon polaritons (SPPs) on a one dimensional (1D) silver nano-grating device, simulated on glass substrate, which can sense a very small change in the refractive index of an analyte adjacent to it. The most recent modeling technique finite element analysis is applied in this work by using a COMSOL RF module. The models of 1D grating devices of different slit widths with fixed periodicity and film thickness are simulated.

"Clinicopathological features and treatment outcomes of differentiated thyroid cancer in Saudi children and adults".

Introduction: Age is an important prognostic factor in differentiated thyroid cancer (DTC). Our aim was to evaluate differences in clinicopathological features and treatment outcomes among children and adult patients with DTC.

Materials And Methods: We studied 27 children (below 18 years) with DTC treated during the period 2000-2012 and were compared with (a) 78 adults aged 19-25 years and (b) 52 adults aged 26-30 years treated during the same period in terms of their clinicopathological features and long term treatment outcomes.

Optic Nerve Metastasis from Squamous Cell Carcinoma of the Uterine Cervix.

Metastatic involvement of the optic nerve or its sheath is very rare (1.3 - 3%). The most common malignancies reported to metastasize to the optic nerve or its sheath are breast, lung, kidney, bladder, gastric and colorectal cancers.

Skull base metastasis from papillary thyroid carcinoma: a report of three cases.

Skull base metastasis from differentiated thyroid carcinoma, including papillary and follicular thyroid carcinoma, is a rare manifestation. Herein, we present three cases of skull base metastasis of papillary thyroid carcinoma. The mean age of the patients was 68.

Duodenal metastasis from lung adenocarcinoma: A rare cause of melena.

Introduction: We report a rare case of duodenal metastasis from primary lung adenocarcinoma presented with history of melena and weight loss.

Presentation Of Case: A 52-year-old smoker man presented with six months history of epigastric pain, melena and weight loss. Esophago-gastroduodenoscopy revealed a 10mm ulcerative lesion in the fourth part of duodenum.

Adenocarcinoma of oesophagus metastasising to the subcutaneous soft tissue.

Skin and subcutaneous metastases are uncommon, and mostly originating from cancers of the breast, kidney, colon, lung, and melanoma. Oesophageal cancers rarely metastasise to the skin and subcutaneous soft tissue. Skin and subcutaneous metastases are associated with dismal prognosis.

Renal cell carcinoma metastatic to thyroid gland, presenting like anaplastic carcinoma of thyroid.

Background. Renal cell carcinoma (RCC) has unpredictable and diverse behavior. The classic triad of hematuria, loin pain, and abdominal mass is uncommon.

Pancreas as delayed site of metastasis from papillary thyroid carcinoma.

Introduction. Follicular variant (FV) papillary thyroid carcinoma (PTC) has aggressive biologic behavior as compared to classic variant (CV) of PTC and frequently metastasizes to the lungs and bones. However, metastasis to the pancreas is extremely rare manifestation of FV-PTC.

Skeletal muscle metastasis as an initial presentation of follicular thyroid carcinoma: a case report and a review of the literature.

Introduction. Follicular thyroid carcinoma (FTC) frequently metastasizes to the lungs and bones. However, metastasis to the skeletal muscles is an extremely rare manifestation of FTC.
