BACKGROUND AND IMPORTANCE: Dissection of cerebellopontine angle (CPA) tumors that abut or adhere to the brainstem or cranial nerves can be a challenging surgical endeavor. We describe the use of semitranslucent latex rubber pledgets in the tumor-brain interface as a method to improve visualization and protection of vital tissue during microsurgical dissection of CPA masses. The rubber pledgets are fashioned by cutting circular discs out of the cuff portion of talc-free, partially opaque latex gloves...

BACKGROUND: Symptomatic malignant pleural effusion (MPE) occurs frequently in patients with metastatic cancer. The associated prognosis is poor and the success rate of talc pleurodesis (TP) is low. Indwelling pleural catheters (IPCs) are commonly inserted when TP has been unsuccessful. METHODS: We compared talc pleurodesis with the use of an indwelling pleural catheter in patients with recurrent MPE in a multicenter randomized controlled trial (superiority design)...

Organic-inorganic hybrid layered materials are proposed as additives in a quasi-solid gel electrolyte for dye-sensitized solar cells. Talcs could provide a low-cost and environmentally friendly, as well as abundant, option as gelators. Here, talcs were prepared by functionalizing an organotalc with three polyamidopyridine dendron generations, PAMPy-talc-Gn (n = 1, 2 and 3). PAMPy dendrons grow parallel to the lamellae plane and form an organized structure by intermolecular interactions. In addition, polyiodide-dendron charge-transfer complexes were prepared onto the organotalc by adsorption of iodine...

BACKGROUND: The suggestion that spontaneous pneumothorax (SP) may result from diffuse porosity rather than discrete anatomic abnormality challenges the practice of targeted bullectomy. We assessed whether underlying pulmonary abnormalities are correlated or could be predicted from the mode of presentation, with potential implications for treatment. MATERIALS AND METHODS: We analyzed 192 consecutive video-assisted thoracoscopic surgery resections for SP (139 primary, 53 secondary) in 171 patients (115 male, age 36, range, 16 to 81)...

We attempted to study the compatibility among plant beneficial bacteria in the culture level by growing them near in the nutrient agar plates. Among all the bacteria tested, Rhizobium was found to inhibit the growth of other bacteria. From the compatible group of PGPR, we have selected one biofertilizer (Azospirillum brasilense strain TNAU) and one biocontrol agent (Pseudomonas fluorescens strain PF1) for further studies in the pot culture. We have also developed a bioformulation which is talc powder based, for individual bacteria and mixed culture...

The size, shape and distribution of different phases in thermoplastic polyolefin (TPO) blends and composites are critical to the properties of the materials, but can be difficult to characterise. Here we report the combination of heavy metal staining and focused ion beam - scanning electron microscopy (FIB-SEM) to reveal the three-dimensional (3D) structure of an elastomer-modified poly(propylene) and a talc filled elastomer-modified poly(propylene). High-quality, high-resolution serial images were collected and the 3D structures were characterised quantitatively...

Ovarian cancer (OC) is the seventh most commonly diagnosed cancer among women in the world and the tenth most common in China. Epithelial OC is the most predominant pathologic subtype, with five major histotypes that differ in origination, pathogenesis, molecular alterations, risk factors, and prognosis. Genetic susceptibility is manifested by rare inherited mutations with high to moderate penetrance. Genome-wide association studies have additionally identified 29 common susceptibility alleles for OC, including 14 subtype-specific alleles...

RATIONALE: During diagnostic thoracoscopy, talc pleurodesis following biopsy is appropriate if the probability of malignancy is sufficiently high. Findings on direct visual assessment of the pleura during thoracoscopy, rapid onsite evaluation (ROSE) of touch preparations (touch preps) of thoracoscopic biopsy specimens and preoperative imaging, may help predict the likelihood of malignancy; however, data on the performance of these methods are limited. OBJECTIVE: To assess the performance of ROSE of touch preps, direct visual assessment of the pleura during thoracoscopy and preoperative imaging in diagnosing malignancy...

INTRODUCTION: Talc pleurodesis is a well-established procedure performed to obliterate the pleural space to prevent recurrent pleural effusion and/or recurrent pneumothorax. Pleurodesis is commonly accomplished by draining the pleural fluid, if present, followed by either a mechanical procedure, such as abrasion, pleurectomy, or instillation of a chemical irritant into the pleural space, which results in inflammation and fibrosis which obliterates the pleural space. The reported complications of talc pleurodesis are hypoxemia, hypotension, tachycardia, dyspnea, chest pain, and fever...

The objective of this study was to explain curing phenomena for pellets coated with a flexible polymeric coating based on poly(vinyl acetate) (Kollicoat(®) SR 30D) with regard to the effect of starter cores, thickness of drug layer, adhesion of coating to drug-layered-cores as well as coating properties. In addition, appropriate approaches to eliminate the curing effect were identified. Sugar or MCC cores were layered with the model drugs carbamazepine, theophylline, propranolol HCl, tramadol HCl and metoprolol HCl using HPMC (5 or 25% w/w, based on drug) as a binder...
