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...

BACKGROUND: Despite a remarkable increase in the depth of our understanding and management of breast cancer in the past 50 years, the disease is still a major public health problem worldwide and poses significant challenges. The palpability of breast tumors has facilitated diagnosis and documentation since ancient times. The earliest descriptions of breast cancer date back to around 3500 BCE. For centuries to follow, theories by Hippocrates (460 BCE) and Galen (200 CE), attributing the cause of breast cancer to an "excess of black bile" and treatment options including the use of opium and castor oil, prevailed...

Tuberculosis (TB) is still a major health problem and TB hospital readmission could increase health system costs. In a retrospective study in a tertiary referral hospital for TB in Tehran, Iran, TB patients with readmission were evaluated. These TB patients in the index year who were then readmitted were compared with TB patients in the same year who were not readmitted during the follow-up period. One hundred and forty-six patients had hospital readmission within three-year follow-up with mean age of 51.6 years old of whom 78 patients (53...

BACKGROUND: The mu-opioid receptor, encoded by mu-opioid receptor gene (OPRM1), has an important role in the development of addiction to opioids. Its aberrant reduction on the cell membrane is responsible, at least in part, for tolerance and physical dependence. OBJECTIVES: The present study was designed to identify the relationship between opium consumption and epigenetic mechanisms involved in opium addiction. METHODS: Genomic DNA was extracted from the peripheral blood of 66 men with opium use disorder and 57 healthy men as a control group...

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...

The lack of adequate access to opioids in India as analgesics and for agonist therapies, forces millions to live with severe unalleviated pain, or languish with suffering associated with drug dependence. Although India is a major opium exporter, the excessively prohibitive 1985 narcotics law formulated to control harmful use of drugs, impeded the availability and access to opioids for medical and scientific purposes. Amendment of this law in 2014 established a new national regulatory framework for improved access to essential opioid analgesics...

BACKGROUND: Following vaginal surgery oral and parenteral narcotics are commonly used for pain relief and their use may exacerbate the incidence of sedation, nausea, and vomiting; ultimately delaying convalescence. Previous studies have demonstrated that rectal analgesia following surgery results in lower pain scores and less intravenous morphine consumption. Belladonna and opium (B&O) rectal suppositories may be used to relieve pain and minimize side effects; however their efficacy has not been confirmed...

Norcoclaurine synthase (NCS) catalyzes the enantioselective Pictet-Spengler condensation of dopamine and 4-hydroxyphenylacetaldehyde as the first step in benzylisoquinoline alkaloid (BIA) biosynthesis. NCS orthologs in available transcriptome databases were screened for variants that might improve the low yield of BIAs in engineered microorganisms. Databases for 21 BIA-producing species from four plant families yielded 33 assembled contigs with homology to characterized NCS genes. Predicted translation products generated from nine contigs consisted of two to five sequential repeats, each containing most of the sequence found in single-domain enzymes...

BACKGROUND: Colorectal cancers (CRCs) including colon, rectum and anal cancers are the third most prevalent cancers in the world. There are strong evidence showing the risk of the cigarette smoking, alcohol use, low physical activity and some types of diets in CRCs; however, few studies explored the relationship between opium use and CRCs. This study aimed to investigate the association between opioid use and the incidence of CRCs. METHODS: In a population-based matched case-control study in Kerman, Iran, 175 patients with colorectal cancers and 350 healthy controls (matched for age, sex, and place of residence) were interviewed from Sep 2014 to Nov 2014...

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...

Retroperitoneal fibrosis (RPF) is a rare condition with an unclear etiology, presenting with the development of aberrant chronic nonspecific fibroinflammatory tissue in the retroperitoneal space, which can result in entrapment and obstruction of the retroperitoneal structures. RPF is a subtype of chronic periaortitis, and can be divided into two types: primary (or idiopathic) and secondary. RPF is usually idiopathic, but can also be secondary to malignancies, certain drugs, infections, surgery, and trauma. The systemic clinical manifestations are nonspecific and include low-grade fever, fatigue, anorexia, weight loss, and myalgia...
