Vine weevil, also known as black vine weevil, (Otiorhynchus sulcatus) is an economically important pest affecting soft fruit and nursery stock in temperate regions. We used laboratory and polytunnel experiments to investigate a novel control system based on autodissemination of spores of an entomopathogenic fungus to populations of adult vine weevils. The fungus was applied as a conidial powder, used on its own or formulated with talc, to a simple plastic refuge for vine weevils. The potential for adult weevils to disseminate the fungus was investigated first in polytunnel experiments using fluorescent powders applied to the refuge in lieu of fungal conidia...

The purpose of this paper was to assess the role of non-asbestiform amphibole EMPs in the etiology of mesotheliomas in taconite (iron ore) miners. Increased mesothelioma rates have been described in Minnesota taconite workers since the late 1990s. Currently, over 100 cases have been reported by the Minnesota Department of Health within the complete cohort of miners in Minnesota. Geologic sampling has indicated that only the eastern part of the iron range contains non-asbestiform amphibole elongate mineral particles (EMPs), in close proximity to the ore...

INTRODUCTION: Pulmonary intravascular talcosis is a rare condition occurring in intravenous drug users injecting oral medications. Talc results in a foreign-body granulomatous reaction giving a radiological haematogenic miliary appearance mimicking miliary tuberculosis. Drug users represent a population at risk for both these conditions and their distinction may be challenging. CASE REPORT: We reported the case of a man, 33 year-old, intravenous drug addict, detected by the health services because he was the partner of a person who died of contagious and multi-resistant tuberculosis...

BACKGROUND: Malignant pleural effusion (MPE) represents a very common cause of pleural exudates, and is one of the most challenging pleural disorders to manage. This could be attributed to the paucity of high-quality experimental evidence, and inconsistent practice worldwide. South Africa (SA) currently has no data regarding the aetiology of MPE. OBJECTIVES: To identify the most common malignancies causing MPE in a population served by a large tertiary hospital in SA, and specifically the relative contribution of mesothelioma...

BACKGROUND: Malignant pleural effusion affects more than 750,000 persons each year across Europe and the United States. Pleurodesis with the administration of talc in hospitalized patients is the most common treatment, but indwelling pleural catheters placed for drainage offer an ambulatory alternative. We examined whether talc administered through an indwelling pleural catheter was more effective at inducing pleurodesis than the use of an indwelling pleural catheter alone. METHODS: Over a period of 4 years, we recruited patients with malignant pleural effusion at 18 centers in the United Kingdom...

The goal of dipping the umbilical cord after birth in calves is to promote healing of the umbilical stump, prevent infection, and encourage the umbilical tissue to detach from the body. Treatment applied to the umbilical area is an important management step for preventing morbidity and mortality in calves. The objective of this study was to compare the effect of 4 umbilical dips on the healing rate, incidence of infection, and age at umbilical cord detachment using newborn Holstein heifer calves (n = 73). Calves were alternately assigned by birth order to 4 treatment groups: 7% iodine, a dry dip formulated using an antibacterial peptide (nisin) mixed with talc (3...

Pulmonary infections are life-threatening complications in patients with spinal cord injuries. In particular, paraplegic patients are at risk if they are ventilator-dependent. This case history refers to a spinal cord injury with a complete sensorimotor tetraplegia below C2 caused by a septic scattering of an intraspinal empyema at C2-C5 and T3-T4. A right-sided purulent pneumonia led to a complex lung infection with the formation of a pleuroparenchymal fistula. The manuscript describes successful, considerate, non-surgical management with shortterm separate lung ventilation...

A 70-year-old Japanese man with recurrent squamous cell carcinoma of the head and neck presented with severe interstitial pneumonia associated with nivolumab, after talc slurry pleurodesis. Following the development of malignant pleural effusion, he underwent chest drainage and was administered intrathoracic talc as a pleurodesis. Two weeks later, we administered nivolumab (3mg/kg) to be repeated every 2 weeks. However, on day 12, chest computed tomography scan demonstrated diffuse non-segmental ground-glass opacity and mild bronchiectasis...

Background: Malignant pleural effusion is a commonly seen complication of malignancies such as lung and breast cancers. In Western countries, talc is frequently used as a standard therapeutic agent (pleurodesis agent) with the aim of alleviating symptoms including dyspnea and chest pain. Talc is not recognized as a pleurodesis agent in Japan. The aim of this study was to verify the efficacy and safety of sterilized talc (NPC-05) for the introduction of talc in Japan. Methods: The study was a single-arm, open-label, investigator-initiated trial conducted jointly at six institutions...

In this study, the electromagnetic (EM) performance of talc/NiTiO3 composite was evaluated. The morphology of talc displayed a lamella structure; there were many nanoparticles of NiTiO3 coated on the talc lamella. Thermal destruction occurred, which increased the surface area from 2.51 m2  g-1 to 79.09 m2  g-1 at the calcined stage at 650°C. The presence of NiTiO3 increased dielectric loss and magnetic loss of talc. The calculation of EM wave absorption of talc/NiTiO3 obtained a maximum reflection loss of -11...

The purpose of this study was to use statistical design of experiments to develop a stable aqueous enteric coating formulation containing stabilizing excipients, such as polyethylene glycol that can minimize hydroxypropyl methylcellulose acetate succinate aggregation and minimize spray-nozzle clogging at elevated processing temperatures. The mechanisms of stabilization (i.e. charge stabilization and molecular interactions) were studied by performing zeta potential and FTIR studies. Electrostatic stabilization by sodium lauryl sulfate and hydrogen bonding by polyethylene glycol provided dispersion stability and yielded a stable aqueous coating formulation that prevented spray-nozzle clogging...

REVIEW
Rachelle Asciak, Najib M Rahman
Malignant pleural effusion is a common complication of cancer and denotes a poor prognosis. It usually presents with dyspnea and a unilateral large pleural effusion. Thoracic computed tomography scans and ultrasound are helpful in distinguishing malignant from benign effusions. Pleural fluid cytology is diagnostic in about 60% of cases. In cytology-negative disease, pleural biopsies are helpful. Current management is palliative. Previously, first-line treatment for recurrent symptomatic malignant pleural effusion was chest drain insertion and talc pleurodesis, with indwelling pleural catheter insertion reserved for patients with trapped lung or failed talc pleurodesis...

We have developed methods to measure the directional-hemispherical (ρ) and diffuse (ρd) reflectances of powders, liquids, and disks of powders and solid materials using a commercially available, matte gold-coated integrating sphere and Fourier transform infrared spectrometer. To determine how well the sphere and protocols produce quantitative reflectance data, measurements were made of three diffuse and two specular standards prepared by the National Institute of Standards and Technology (NIST), LabSphere Infragold and Spectralon standards, hand-loaded sulfur and talc powder samples, and water...
