Herbal Therapeutics in Osteoporosis: Mechanisms, Evidence, and Translational Potential

Phytotherapy Research, EarlyView.
Schematic overview of bone remodeling dysregulation in osteoporosis and the multi‐target protective role of herbal therapeutics. ABSTRACT Osteoporosis is a chronic bone disease marked by reduced density and increased fracture risk. Current treatments face limitations in safety, efficacy, and long‐term adherence, prompting interest in alternative ...

Occupational Exposure to Talc Increases the Risk of Lung Cancer: A Meta-Analysis of Occupational Cohort Studies

Canadian Respiratory Journal, 2017
Objective. Talc is widely used in industrial applications. Previous meta-analyses of carcinogenic effects associated with inhaled talc included publications before 2004, with a lack of data in China, the largest talc-producing country.

Laponite Network Controls FGF‐2 Release and Drives Functional Nerve Regeneration via 3D‐Printed Nerve Wrap Interfaces

Small Methods, EarlyView.
We developed a 3D‐printed nerve interface integrating a biomimetic nanocomposite hydrogel with sustained delivery of thermostable FGF‐2. The bioactive interface supports Schwann cell activity and myelination while providing a regenerative microenvironment.

Influence of talc genesis and particle surface on the crystallization kinetics of polypropylene/talc composites [PDF]

, 2012
Talc is a laminar silicate, considered as an excellent nucleating agent for polypropylene (PP) crystallization. However, properties of PP/talc composites depend on the morphology, size, and surface of mineral particles.

Talc‐Tempered Pottery From Bala Hissar, Kabul: An Analytical Study

Archaeometry, EarlyView.
ABSTRACT Potsherds of cooking ware excavated at Bala Hissar archaeological site in Kabul were studied using X‐ray fluorescence (XRF), scanning electron microscope‐energy dispersive X‐ray spectrometry (SEM‐EDS), Raman spectroscopy, X‐ray powder diffraction (XRPD), thermogravimetric analysis (TGA) and optical microscopy.

Processes and Patterns of Dolomite Precipitation in Aptian Pre‐Salt Deposits of Santos Basin, Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Aptian pre‐salt lacustrine carbonates represent the most significant oil exploration target along the South Atlantic margin. Dolomitization of the Santos Basin Barra Velha Formation (BVF) is critical for reservoir quality, yet its origin, patterns, and evolution remain poorly understood.

Chest ultrasonography to assess the kinetics and efficacy of talc pleurodesis in a model of pneumothorax: an experimental animal study

ERJ Open Research, 2018
Talc pleurodesis is used to avoid recurrences in malignant pleural effusions or pneumothorax. The lack of lung sliding detected by chest ultrasonography (CUS) after talc application is indicative of the effectiveness of pleurodesis.

‘Chrystalline Talk’: Thomas Browne's Poetics of Concretion and Mineral Plain Style

Renaissance Studies, EarlyView.
ABSTRACT This article charts the figuration, both material and rhetorical, of mineral bodies in early modern natural philosophy, paying particular attention to the second book of Thomas Browne's Pseudodoxia Epidemica (1646). It argues that concretions (stony calculi and crystals formed through the aggregation of physical matter) make manifest a mineral

Avicenna on the PSR and Causal Necessity in the Natural World

Theoria, EarlyView.
ABSTRACT Avicenna's account of causal necessity in the natural world is a key part of his metaphysical system and it is also historically significant. Yet, there is little scholarly discussion of the philosophical basis of his view. This is surprising not only because the topic is important, but also because the view is challenging to interpret ...
