We report a Mg alloy Mg-2.2Nd-0.1Zn-0.4Zr (wt.%, denoted as JDBM-2) showing great potential in clinical vascular stent application by integrating the advantages of traditional medical stainless steel and polymer. This alloy exhibits high yield strength and elongation of 276 ± 6 MPa and 34.3 ± 3.4% respectively. The JDBM-2 with a stable degradation surface results in a highly homogeneous degradation mechanism and long-term structural and mechanical durability. In vitro cytotoxicity test of the Mg extract via human vascular endothelial cells (HUVECs) indicates that the corrosion products are well tolerated by the tested cells and potentially negligible toxic effect on arterial vessel walls...

In recent years, new drugs have been designed for treating advanced cutaneous malignant melanoma, in particular the metastases. They afford modest benefits despite the fact they are commonly heralded as breakthroughs in the lay press and by some medical opinion leaders. Unfortunately, the use of inflated descriptors of the drug efficacy leads to misunderstandings among the clinicians in charge of patients. Currently, vemurafenib, ipilimumab, pembrolizumab and nivolumab have demonstrated their relative activity in the control of advanced malignant melanoma...

HIV pre-exposure prophylaxis (PrEP) is the use of one or more antiretroviral medications (in combination) to prevent HIV infection. The most commonly used PrEP medication (Truvada(®) , Gilead Sciences, Inc.) acts by inhibiting HIV-1 reverse transcriptase. If someone who is using PrEP unknowingly becomes HIV infected (termed 'PrEP breakthrough infection'), there may be suppressed viral replication resulting in a virus level undetectable by the most sensitive HIV NAT. Failure to seroconvert and seroreversion (loss of previously detectable HIV antibodies) have also both been observed with 2nd, 3rd and 4th generation screening immunoassays, as well as Western blot assays...

REVIEW
Yuqi Chen, Tingting Hong, Shaoru Wang, Jing Mo, Tian Tian, Xiang Zhou
The epigenetic modification of nucleic acids represents one of the most significant areas of study in the field of nucleic acids because it makes gene regulation more complex and heredity more complicated, thus indicating its profound impact on aspects of heredity, growth, and diseases. The recent characterization of epigenetic modifications of DNA and RNA using chemical labelling strategies has promoted the discovery of these modifications, and the newly developed single-base or single-cell resolution mapping strategies have enabled large-scale epigenetic studies in eukaryotes...

The inflammatory activity of ulcerative colitis plays an important role in the medical treatment. However, accurate and real-time monitoring of the colitis activity with noninvasive bioimaging method is still challenging, especially in distinguishing between chronic and acute colitis. As a good receptor, the oligopeptide transporter (PepT1) is overexpressed in the colonic epithelial cells of chronic ulcerative colitis, which can deliver tripeptide KPV (Lys-Pro-Val, the C-terminal sequence of α-MSH) into cytosol in the intestine...

In the present study, we sought to evaluate the prophylactic use of octreotide for asparaginase-induced acute pancreatitis. We reviewed the medical records of seven patients in two institutions who received prophylactic octreotide for re-administration of asparaginase after asparaginase-induced acute pancreatitis. Three patients completed asparaginase treatment without developing pancreatitis, and four experienced recurrence of pancreatitis. A literature search using PubMed identified four additional patients in whom asparaginase was successfully re-administered with octreotide...

REVIEW
Li Ren, Gang Chen
ETHNOPHARMACOLOGICAL RELEVANCE: Yueju is a traditional herbal medicine which consists of five herbs and formulated to treat depression-related syndromes 800 years ago. Yueju is still widely prescribed to treat conditions which include digestive dysfunction and depression. Recently, Yueju has been shown to promote a fast-onset antidepressant effect clinically and in preclinical studies. Because conventional antidepressants have a delayed onset in treating depression, the novelty of Yueju's rapid antidepressant effect and its underlying mechanism are of great significance both clinically and scientifically...

Saeedeh Ansari, Majid Karimi
Since the introduction of the molecularly imprinting technology (MIT) in the 1970s, it becomes an emerging technology with the potential for wide-ranging applications in drug determination. With the rise of green chemistry, many researchers began to focus on the application and development of green materials which led to the breakthrough of molecularly imprinted polymers (MIPs) in the green chemistry. Because of the low concentration levels in the human matrices, almost adequate analytical methods should be used for quantification of drugs at the trace levels...

Huntington's disease (HD) is an autosomal dominantly inherited neurodegenerative disease characterized by progressive motor, behavioral, and cognitive decline, ending in death. Despite the discovery of the underlying genetic mutation more than 20 years ago, treatment remains focused on symptomatic management. Chorea, the most recognizable symptom, responds to medication that reduces dopaminergic neurotransmission. Psychiatric symptoms such as depression and anxiety may also respond well to symptomatic therapies...

Pain is prevalent in advanced malignancies; however, some patients cannot get adequate pain relief by conservative routes of analgesic administration or experience serious side effects related to high dose of opioids. For those who have exhausted multimodal conservative analgesic, intrathecal drug delivery is an alternative intervention for truly effective pain management. The objective of this study was to evaluate the clinical efficacy and safety of intrathecal drug delivery system (IDDS) for the treatment of intractable pain in advanced cancer patients...

Vijay Tripathi, Eddie Cytryn
Antibiotics are considered to be one of the major medical breakthroughs in history. Nonetheless, over the past four decades, antibiotic resistance has reached alarming levels worldwide and this trend is expected to continue to increase, leading some experts to forecast the coming of a 'post-antibiotic' era. Although antibiotic resistance in pathogens is traditionally linked to clinical environments, there is a rising concern that the global propagation of antibiotic resistance is also associated with environmental reservoirs that are linked to anthropogenic activities such as animal husbandry, agronomic practices and wastewater treatment...

BACKGROUND: The introduction of deep brain stimulation (DBS) about 25 years ago provided one of the major breakthroughs in the treatment of Parkinson's disease (PD). However, a high percentage of patients are reluctant to undergo DBS. Previous research revealed that the critical step on the patient's path to DBS is the decision whether to undergo further diagnostic assessment for surgery at a specialized DBS-center. The aims of the current study were to evaluate how effective the combination of an outpatient DBS screening tool, STIMULUS, with specially developed educational material was to enhance patient education on DBS and to identify motivational aspects which influenced the patients' willingness to undergo further assessment...

The period of British rule from 1757 to 1900 is marked by major sociopolitical changes and scientific breakthroughs that impacted medical systems, institutions, and practitioners in India. In addition, historians have debated whether the colonial regime used Western medicine as a tool to expand and legitimize its rule. This paper reviews the secondary literature on this subject with emphasis on the individual physicians. During this period, the practice of "Doctory" or Western medicine gained momentum in India, buoyed with the support of the British as well as Western-educated Indians...
