Papaverine is a non-narcotic alkaloid found endemically and uniquely in the latex of the opium poppy. It is normally refined out of the opioids that the latex is typically collected for, hence its presence in a sample is strong prima facie evidence that the carrier from whom the sample was collected is implicated in the mass cultivation of poppies or the collection and handling of their latex. We describe an analysis technique combining surface-enhanced Raman spectroscopy (SERS) with microfluidics for detecting papaverine at low concentrations and show that its SERS spectrum has unique spectroscopic features that allows its detection at low concentrations among typical opioids...

From the beginning of the 19th century to the Opium War, by taking the advantages of free entering and departing China, and to protect themselves, the foreign firms introduced vaccination technique into China. This is the beginning of the introduction of western medicine to China. After 1807, following the arrival of protestant missionaries, foreign firms became the stronghold for the missionaries to conceal their missionary status so as to propagate the principles of Christianity. With the aid of the business firms employee's legal identity, the missionaries started their activities of delivering western medicines and practices...

Esophageal squamous cell carcinoma (ESCC) is an aggressive tumor that is typically diagnosed only when the tumor has gained remarkable size, extended to peripheral tissues, and led to dysphagia. Five-year survival of advanced cancer is still very poor (19%), even with improved surgical techniques and adjuvant chemoradiation therapy. Therefore, early detection and prevention are the most important strategies to reduce the burden of ESCC. Our review will focus on the studies conducted in Golestan province, an area with a high prevalence of ESCC in northern Iran...

While opioids are very effective analgesics for treating acute pain, humans have struggled with opiate addiction for millenia. An opium abuse epidemic in the early 1900's led the US government to develop a systematic research infrastructure and scientific plan to produce new compounds with analgesic properties but without abuse liability. This review describes the techniques that were developed for testing in the human laboratory, including empirically derived outcome measures and required elements for human abuse potential assessment...

The incidence of smuggling and transporting illegal substances by internal concealment, also known as body packing, is on the rise. The clinical approach to such patients has been changed significantly over the past 2 decades. However, despite a recorded increase in body packing in general, there are controversies in the management of these patients. We aimed to gather data regarding the demographic characteristics, treatment, and outcome of body packers, which were that referred to Loghman Hakim Hospital, Tehran, Iran...

Opium addiction is one of the main health problems in developing countries and induces serious defects on the human body. In this work, the concentrations of 32 minerals including alkaline, heavy and toxic metals have been determined in the iliac crest bone tissue of 22 opium addicted individuals using inductively coupled plasma-optical emission spectroscopy (ICP-OES). The bone tissues of 30 humans with no physiological and metabolomic diseases were used as the control group. For subsequent analyses, the linear and quadratic discriminant analysis techniques have been used for classification of the data into "addicted" and "non-addicted" groups...

Heinrich von Pfalzpaint (circa 1415-1465) was a Bavarian military surgeon of the Teutonic Order who treated more than 4000 casualties during the siege of Marienberg Fortress (1454-1457). In 1460, he reported "How to create a new nose if it has been chopped off and the dogs have eaten it" in his treatise on wound care Bündt-Ertznei. He used opium-soaked sponges for anesthesia, described the surgical extraction of bullets and cleft lip repair. Pfalzpaint would have been the first author to describe nasal reconstruction in Europe if his treatise had not been lost...

Covering: up to December 2013. Over the past decade, there has been a growing transition in recreational drugs from natural materials (marijuana, hashish, opium), natural products (morphine, cocaine), or their simple derivatives (heroin), to synthetic agents more potent than their natural prototypes, which are sometimes less harmful in the short term, or that combine properties from different classes of recreational prototypes. These agents have been named smart drugs, and have become popular both for personal consumption and for collective intoxication at rave parties...

Discovery of fire at the dawn of prehistoric time brought not only the benefits to human beings offering the light and heat, but also misfortune due to burns; and that was the beginning of burns treatment. Egyptian doctors made medicines from plants, animal products and minerals, which they combined with magic and religious procedures. The earliest records described burns dressings with milk from mothers of male babies. Goddess Isis was called upon to help. Some remedies and procedures proved so successful that their application continued for centuries...

Beauveria bassiana strain 04/01-Tip obtained from larvae of the opium poppy stem gall Iraella luteipes endophytically colonizes opium poppy plants and protect it against this pest. Development of a specific, rapid and sensitive technique that allows accurately determining the process and factors leading to the establishment of this strain in opium poppy plants would be essential to achieve its efficient control in a large field scale. For that purpose in the present study, species-specific primers that can be used in conventional or quantitative PCR protocols were developed for specifically identification and detection of B...

In order to develop a sensor for opium alkaloid codeine detection, DNA aptamers against codeine were generated by SELEX (systematic evolution of ligands by exponential enrichment) technique. An aptamer HL7-14, which is a 37-mer sequence with Kd values of 0.91 μM, was optimized by the truncation-mutation assay. The specificity investigation shows that HL7-14 exhibits high specificity to codeine over morphine, and almost cannot bind to other small molecule. With this new selected aptamer, a novel electrochemical label-free codeine aptamer biosensor based on Au-mesoporous silica nanoparticles (Au-MSN) as immobilized substrate has been proposed using [Fe(CN)6](3-/4-) as electroactive redox probe...

Our speciality commonly traces its origin to a demonstration of the inhalation of ether by a patient undergoing surgery in Boston in 1846. Less well known is the demonstration of the i.v. injection of opium with alcohol into a dog in Oxford in 1656, leading to anaesthesia followed by full long-term recovery. After gaining i.v. access, a mixture of opium and alcohol was injected, resulting in a brief period of anaesthesia. After a period during which the dog was kept moving to assist recovery, a full recovery was made...
