Simultaneous Electrospinning and Electrospraying for the Preparation of a Precursor Membrane Containing Hydrothermally Generated Biochar Particles to Produce the Value-Added Product of Carbon Nanofibrous Felt.

Biochar is a byproduct generated from the hydrothermal liquefaction of biomass, such as corn stover, in an anaerobic environment. This work aims to convert biochar into a value-added product of carbon nanofibrous felt. First, the biochar-containing precursor membrane was prepared from simultaneous electrospinning and electrospraying.

Obesity paradox in cancer: Is bigger really better?

While obesity is widely recognized as a risk factor for cancer, survival among patients with cancer is often higher for obese than for lean individuals. Several hypotheses have been proposed to explain this "obesity paradox," but no consensus has yet emerged. Here, we propose a novel hypothesis to add to this emerging debate which suggests that lean healthy persons present conditions unfavorable to malignant transformation, due to powerful natural defenses, whereby only rare but aggressive neoplasms can emerge and develop.

Applicability of transoral endoscopic parathyroidectomy through vestibular route for primary sporadic hyperparathyroidism: A South Indian experience.

Introduction: Primary hyperparathyroidism is one of the most common endocrine disorders requiring surgical parathyroidectomy for its definitive treatment. Surgical exploration is traditionally performed through conventional open neck approach. A wide range of minimal access and minimally invasive endoscopic techniques (gas less and with gas) have been attempted in the past two decades.

Feasibility of thoracoscopic approach for retrosternal goitre (posterior mediastinal goitre): Personal experiences of 11 cases.

Introduction: Posterior mediastinal goitres constitute of a unique surgical thyroid disorder that requires expert management. Occasionally, they require thoracic approach for the completion of thyroidectomy. In this paper, we describe the feasibility and utility of a novel thoracoscopic approach for such goitres.

Development and Validation of the Athlete Fear Avoidance Questionnaire.

Context: The fear-avoidance model was developed in an attempt to explain the process by which "pain experience" and "pain behavior" become dissociated from the actual pain sensation in individuals who manifest the phenomenon of exaggerated pain perception. High levels of fear avoidance can lead to chronic pain and disability and have successfully predicted rehabilitation time in the work-related-injury population. Existing fear-avoidance questionnaires have all been developed for the general population, but these questionnaires may not be specific enough to fully assess fear avoidance in an athletic population that copes with pain differently than the general population.
