REVIEW
Peng Zhang, Xi-Wen Li, Lin-Lin Dong, Shi-Lin Chen
The issues including excessive pesticide residues and heavy metal contamination have become the bottle-neck in the development of Chinese herbal medicines. Compared with traditional chemical pesticides, biological pesticides, especially botanical pesticides, are more safe and environment-friendly, which were beneficial to the quality improvement Chinese medicinal materials. Though there exists a weak basic research and it is hard for promotion and regulation, the policy of good and the desire for botanical pesticides will accelerate its development, and replace traditional chemical pesticides gradually...

In recent years, the research object of traditional Chinese medicine(TCM) analysis has not just been limited to the common analysis technology, but focused on the key relationship between chemical ingredients and traditional functions, including Chinese material medica (CMM) attributes, chemical substance and biological function. Near infrared spectroscopy (NIR) analysis technology, due to its unique advantages, has been developed rapidly in the field of pharmaceutical analysis, especially in the TCM analysis...

Removal of bacterial biofilm from the root canal system is essential for the management of endodontic disease. Here we evaluated the antibacterial effect of N-acetylcysteine (NAC), a potent antioxidant and mucolytic agent, against mature multispecies endodontic biofilms consisting of Actinomyces naeslundii, Lactobacillus salivarius, Streptococcus mutans and Enterococcus faecalis on sterile human dentin blocks. The biofilms were exposed to NAC (25, 50 and 100mg/mL), saturated calcium hydroxide or 2% chlorhexidine solution for 7 days, then examined by scanning electron microscopy...

Riassunto La pubblicazione di Unanticipated outcomes, la storia personale di Jerome P. Kassirer, ex direttore del New England Journal of Medicine, offre l'opportunità di considerare i principi etici dell'editoria biomedica e scientifica. Il conflitto di interessi, le dichiarazioni e la frode influenzano la credibilità della comunicazione medica, che poggia sulla robustezza e sulla trasparenza dei suoi processi. Non tutto è ancora perduto, ma dobbiamo essere guidati da forti principi morali e da un quadro coerente di valori...

Policy Points: Introducing a recent special issue of The Lancet on the health system in France, Horton and Ceschia observe that "the dominance of English as the language of science and, increasingly, global health too often closes the door on the history and experiences of others."(1) In that spirit, this manuscript presents a detailed case study of public health policy transformation in France in the early 1990s. It casts light on processes of policy change in a political and cultural environment very different from that of the United States, showing how the public health policy process is shaped by multiple contingencies of history, ideology, and politics...

INTRODUCTION: Formocresol has been a popular pulpotomy medicament for many years. It is considered the "gold standard" in pediatric dentistry. However, concerns have been raised over its use in children. It has been reported that formocresol has toxic and mutagenic effects in cell culture, dental crypts, and precancerous epithelial cells. Therefore, additional biocompatible treatment alternatives are required to replace formocresol pulpotomy. AIMS: This study compared the clinical and radiographic success rates of ferric sulfate (FS) and bioactive tricalcium silicate cement (Biodentine, Septodont) as pulpotomy agents in primary molar teeth over a period of 9 months...

Investigation of the chemical constituents from the fruits of Citrus medica L. var. sarcodactylis Swingle has led to the characterization of a new sesquiterpene 1 along with thirty-two known compounds. The structure of 1 was established on the basis of 2D NMR spectroscopic and mass spectrometric analyses, and the known compounds were identified by comparison of their physical and spectroscopic data with those reported in the literature. In addition, most of the isolated compounds were evaluated for the activity assayed by the in vitro inhibition of superoxide anion generation and elastase release by human neutrophils...

BACKGROUND: Most often used intracanal medicament is calcium hydroxide (Ca(OH)2). Removal of Ca(OH)2 before obturation is mandatory. Different irrigation solutions and devices were tested in the previous study for this purpose. AIM: The aim of this study was to evaluate the comparative efficacy of different irrigation techniques in removing intracanal medicament using cone-beam computed tomography (CBCT). MATERIALS AND METHODS: Cleaning and shaping was carried out in 42 freshly extracted single-rooted mandibular first premolars using Protaper Rotary Files...

ETHNOPHARMACOLOGICAL RELEVANCE: What are the minimum methodological and conceptual requirements for an ethnopharmacological field study? How can the results of ethnopharmacological field studies be reported so that researchers with different backgrounds can draw on the results and develop new research questions and projects? And how should these field data be presented to get accepted in a scientific journal such as the Journal of Ethnopharmacology? The objective of this commentary is to create a reference that covers the basic standards necessary during planning, conducting and reporting of field research...

ETHNOPHARMACOLOGICAL RELEVANCE: This review focuses on traditional and contemporary anti-inflammatory uses of mollusc-derived products summarising all the in vitro, in vivo and human clinical trials that have tested the anti-inflammatory activity of molluscan natural products. Inflammatory conditions, burns and wounds have been an ongoing concern for human health since the early era of civilisation. Many texts from ancient medicine have recorded the symptoms, signs and treatments for these conditions...

BACKGROUND: Optimal antibacterial efficacy of intracanal medicaments containing silver nanoparticles (Ag-NPs) has been well documented. However, concerns remain regarding the effect of Ag-NPs on tooth color. This study aimed to assess the effects of calcium hydroxide (CH) mixed with Ag-NPs as intracanal medicaments on tooth color. The effect of location of application of medicament on the degree of discoloration was evaluated as well. MATERIAL AND METHODS: Fifty extracted single-rooted, single-canal human teeth with straight roots, no caries, no cracks or fractures were collected and accessed...

BACKGROUND: In many cases, the indirect pulp treatment (IPT) is an acceptable treatment for deciduous teeth with reversible pulp inflammation. Various medicaments have been used for IPT, ranging from calcium hydroxide and glass ionomers to dentin adhesives. OBJECTIVE: This in vitro trial aimed to measure cytotoxicity in a cell culture, comparing the following four adhesives: Xeno® V (XE), Excite® F DSC (EX), Adhese® OneF (AD) and Prime & Bond NT (PB). MATERIALS AND METHODS: The adhesives were prepared according to the manufacturer's instructions...

By sorting out the literature on materiamedica, it is found that medicinal history of ClinopodiumHerba is rather long which can be traced back to caoxuejiein Lüchan yan ben cao (Mountainous Materia Medica) with definite efficacy and usage; it is generally believed that the original plant of ClinopodiumHerba is Clinopodiumpolycephalum (Vaniot) C. Y. Wu et Hsuan and C. chinensis (Benth.) O. Kuntze are two separate species, also some scholarsclaim that C. polycephalum and C. chinensisare the same plant. But I think C...

BACKGROUND: Hemostasis following transradial access (TRA) is usually achieved by mechanical compression. We investigated use of the QuikClot Radial hemostasis pad (Z-Medica) compared with the TR Band (Terumo Medical) to shorten hemostasis after TRA. METHODS: Thirty patients undergoing TRA coronary angiography and/or percutaneous coronary intervention were randomized into three cohorts post TRA: 10 patients received mechanical compression with the TR Band, 10 patients received 30 min of compression with the QuikClot Radial pad, and 10 patients received 60 min of compression with the QuikClot Radial pad...

INTRODUCTION: The aim of this in vitro study was to evaluate and compare the penetration depth of conventional (CH) and nano-particle calcium hydroxide (NCH) into dentinal tubules. METHODS AND MATERIALS: Ninety human single-rooted teeth were instrumented by RaCe rotary system and after chemomechanical preparation were randomly divided in two equal groups (n=45). In the first group conventional CH and in the other NCH was used as intracanal medicament. After 2 weeks of incubation all roots were intentionally split at longitudinal axis and prepared for scanning electron microscope (SEM) observation...
