PURPOSE OF REVIEW: This review summarizes recent data supporting the concept that urinary microRNAs are a useful new class of biomarker. They may improve capacity to stratify patients with chronic kidney disease according to risk of progression, and may also inform about response to therapy. RECENT FINDINGS: MicroRNAs are present, stable and readily quantifiable in tissues and body fluids, including urine, and have widespread importance as regulators in the kidney...

Sijunzi Decoction (SJZD) is a formula used for the treatment of spleen deficiency and gastrointestinal diseases in Traditional Chinese Medicine. Polysaccharides are reported to be the main components of SJZD responsible for its bio-functions. However, highly purified and clearly characterized polysaccharides from SJZD are not well described. Here we obtained a purified polysaccharide (SJZDP-II-I) from SJZD using ion exchange chromatography and gel filtration. Structure analysis by FT-IR and NMR identified SJZDP-II-I as a typical pectic polysaccharide with homogalacturonan and rhamnogalacturonan type I regions and arabinogalactan type I and II as side chains...

Susanna Agardy
Petrie and Weinman urge chronic fatigue syndrome patients to move on from their beliefs about their illness and accept the findings of thePACE trial. This is unreasonable in view of the failure of PACE to achieve evidence of recovery through cognitive behaviour therapy and graded exercise therapy in either self-reports or the objective measure of the 6-minute walking test. Contrary to their suggestion, the Institute of Medicine describes chronic fatigue syndrome not as psychological but as a serious, chronic, systemic disease, with post-exertional malaise as its main feature which inhibits exercise...

Vaccines represent one of the most successful chapters in the history of medicine. Over the past decades, the advent of recombinant cDNA technology has enabled the biomedical community to genetically engineer viruses for vaccine delivery purposes. As a starting point, this review evaluates the unmet medical needs, which drive scientists and industry to exploit such fundamentally new technology for human vaccination. The author discusses the molecular functioning, production and safety profile of replication-competent and -deficient viral vector systems, representing two fundamentally distinct classes of "genetic vaccines"...

The effects of rapid, recent uplift of the Hengduan Mountains on evolution and diversification of young floristic lineages still remain unclear. Here, we investigate diversification of three closely related Saxifraga species with a distribution restricted to the Hengduan Mountains (HM) and southern Tibet, and comment on their taxonomy based on molecular evidence. Three chloroplast DNA fragments (rbcL, trnL-F, trnS-G) and the nuclear ribosomal DNA internal transcribed spacer (ITS) were employed to study genetic structure across 104 individuals from 12 populations of Saxifraga umbellulata, S...

BACKGROUND: Peritoneal metastases (PM), corresponding to tumor implants into the peritoneal cavity, are associated with impaired prognosis and low responsiveness to systemic chemotherapy. A new therapeutic approach has dramatically changed the prognosis of patients with PM from colorectal cancer (CRC), consisting in the association of a complete cytoreductive surgery followed by intraperitoneal chemotherapy associated to hyperthermia (HIPEC). Many drugs have been administered intraperitoneally, but no clear consensus has been approved...

Impulse control disorders (ICDs), such as compulsive gambling, buying, sexual, and eating behaviors, are a serious and increasingly recognized complication in Parkinson's disease (PD), occurring in up to 20% of PD patients over the course of their illness. Related behaviors include punding (stereotyped, repetitive, purposeless behaviors), dopamine dysregulation syndrome (DDS) (compulsive medication overuse), and hobbyism (e.g., compulsive internet use, artistic endeavors, and writing). These disorders have a significant impact on quality of life and function, strain interpersonal relationships, and worsen caregiver burden, and are associated with significant psychiatric comorbidity...

Syzygium aromaticum (L.) Merr. & L.M. Perry (Mirtaceae) and Rosmarinus officinalis L. (Lamiaceae) are both medicinal plants used for centuries to alleviate pain. The aim of the study was to demonstrate the therapeutic potential utility of herb-drug association of S. aromaticum essential oil or R. officinalis ethanolic extract coadministered with ketorolac. Antinociceptive pharmacological interaction was investigated by an isbolographic study using the formalin test in rats. Both alone and in combination with ketorolac; S...

For many years after its invention around 1796, homeopathy was widely used in people and later in animals. Over the intervening period (1796-2016) pharmacology emerged as a science from Materia Medica (medicinal materials) to become the mainstay of veterinary therapeutics. There remains today a much smaller, but significant, use of homeopathy by veterinary surgeons. Homeopathic products are sometimes administered when conventional drug therapies have not succeeded, but are also used as alternatives to scientifically based therapies and licensed products...

Malignant Pleural Mesothelioma (MPM) is an aggressive malignancy highly resistant to chemotherapy, with a response rate of 20% of patients and for this reason an efficient treatment is still a challenge. Platinum-based chemotherapy in association with a third-generation antifolate is the front-line standard of care whereas any second-line treatment was approved for MPM thus making it a pathology that evokes the need for new therapeutic agents. Different platinum-drugs were synthesised and tested as an option for patients who are not candidates to cisplatin-based therapy...

BACKGROUND: Identification of genes whose basal mRNA expression predicts the sensitivity of tumor cells to cytotoxic treatments can play an important role in individualized cancer medicine. It enables detailed characterization of the mechanism of action of drugs. Furthermore, screening the expression of these genes in the tumor tissue may suggest the best course of chemotherapy or a combination of drugs to overcome drug resistance. RESULTS: We developed a computational method called ProGENI to identify genes most associated with the variation of drug response across different individuals, based on gene expression data...

BACKGROUND: Multipotent stromal cells (MSCs) are being studied in the field of regenerative medicine for their multi-lineage differentiation and immunoregulatory capacity. MicroRNAs (miRNAs) are short non-coding RNAs that are responsible for regulating gene expression by targeting transcripts, which can impact MSC functions such as cellular proliferation, differentiation, migration and cell death. miRNAs are expressed in MSCs; however, the impact of miRNAs on cellular functions and donor variability is not well understood...

Malaria, in particular infection with P. falciparum (the most lethal of the human malaria parasite species, responsible for nearly one million deaths every year), is one of the most devastating and common infectious disease throughout the world. Beginning with quinine, quinoline containing compounds have long been used in clinical treatment of malaria and remained the mainstays of chemotherapy against malaria. The emergence of P. falciparum strains resistant to almost all antimalarials prompted medicinal chemists and biologists to study their effective replacement with an alternative mechanism of action and new molecules...

In recent years there has been growing interest in early intervention in psychotic disorders and a number of clinical and research programmes have been developed. The clinical staging model has been an essential part of early intervention as it provides the rationale of existing programmes. In medicine, clinical staging is a valuable approach in disorders where primary pathology is progressive in nature. However, the clinical staging model of psychosis has been proposed without establishing first that schizophrenia is a primarily progressive disorder...

INTRODUCTION: Respiratory tract infections have been an important cause of morbidity and mortality worldwide that is looming large especially in context of antibiotic resistance that is confronted both by a pulmonologist as well as a general practitioner. A reflection to this trend has been the rising phenomenon of MICs as shown the respiratory pathogens towards conventional antibiotics including macrolides or β lactam/β lactamase inhibitor combinations. Respiratory fluoroquinolones offer broad yet potent cover of respiratory pathogens leading to their obvious choice for empirical therapy for clinical persisters or high risk cases with prior history of antibiotics not-withstanding the clinical concerns in tropical countries...
