BACKGROUND: Oxidative stress is strongly implicated in ischemia reperfusion (IR)-mediated functional and neuronal impairment. Therefore, strategies employing antioxidants to reverse the damage due to IR are being investigated. Allium schoenoprasum L. is a culinary medicine whose antioxidant properties are well documented but whose neuroprotective potential has not been examined. Hence, the present study was designed to evaluate the effect of A. schoenoprasum leaf extract (ASLE) on functional deficit against IR-induced cerebral injury in mice...

ETHNOPHARMACOLOGICAL RELEVANCE: Thymus camphoratus and T. carnosus are widely used in Portugal for the treatment of inflammatory-related conditions, such as inflammation of the respiratory tract, being the later also used as an antitussive. AIM OF THE STUDY: Bearing in mind the lack of scientific studies focused on the pharmacological activity of Thymus camphoratus and T. carnosus, this work was designed to validate the anti-inflammatory properties ascribed to these traditional species and concomitantly to unveil both the putative molecular mechanisms behind their bioactivity as well as the safety profile of their essential oils and major compounds...

Panax notoginseng saponin (PNS) constitutes the major effective components of Panax notoginseng, which is widely used to treat microcirculatory disturbance associated diseases. In this study, we designed to investigate the effect of PNS on the treatment of pulmonary fibrosis (PF) and further explored its mechanism. A total of 40 healthy Japanese White rabbits were randomly divided into five groups (control group; PF model group; PNS prevention group; PNS treatment group; and western medicine [prednisone acetate] treatment group)...

BACKGROUND: Mushrooms have been widely considered as health foods as their extracts have anti-hypertensive and anti-tumor activities. After a thorough literature survey, we hypothesized that enzymes in mushroom extracts play an important role in synthesizing functional molecules. Therefore, in the present study, proteins extracted from Reishi mushroom (Ganoderma lucidum), which is used in oriental medicine, were identified by the proteomic approach, and appropriate extraction methods for improving angiotensin-converting enzyme (ACE) inhibitory activities were investigated...

Microtissues (MT) are currently considered as a promising alternative for the fabrication of natural, 3D biomimetic functional units for the construction of bio-artificial substitutes by tissue engineering (TE). The aim of this study was to evaluate the possibility of generating mesenchymal cell-based MT using human umbilical cord Wharton's jelly stromal cells (WJSC-MT). MT were generated using agarose microchips and evaluated ex vivo during 28 days. Fibroblasts MT (FIB-MT) were used as control. Morphometry, cell viability and metabolism, MT-formation process and ECM synthesis were assessed by phase-contrast microscopy, functional biochemical assays, and histological analyses...

Novel approaches for culturing primary human cells in vitro are increasingly needed to study cell and tissue physiology and to grow replacement tissue for regenerative medicine. Conventional 2D monolayer cultures of endometrial epithelial and stromal cells fail to replicate the complex 3D architecture of tissue. A fully synthetic scaffold that mimics the microenvironment of the human endometrium can ultimately provide a robust platform for investigating tissue physiology and, hence, take significant steps towards tackling female infertility and IVF failure...

Background: Multiple sclerosis (MS) is a chronic progressive and inflammatory disease of the central nervous system that is characterized by demyelination in the central nervous system. In regard to the prevalence of diseases and enormous costs imposed on society and the health system, finding a way to stop the progression of the disease using drugs with fewer side effects seems a serious sanitation issue to the health of the international community. This study aimed to evaluate the effect of evening primrose oil (EPO) on fatigue and quality of life in patients with MS...

Bangladesh is one of the world's most vulnerable countries for climate change. This observational study examined the association of temperature, humidity and rainfall with six common climate-sensitive infectious diseases in adults (malaria, diarrheal disease, enteric fever, encephalitis, pneumonia and bacterial meningitis) in northeastern Bangladesh. Subjects admitted to the adult medicine ward of a tertiary referral hospital in Sylhet, Bangladesh from 2008 to 2012 with a diagnosis of one of the six chosen climate-sensitive infectious diseases were enrolled in the study...

BACKGROUND: International Association for Hospice and Palliative Care implemented Opioid Price Watch (OPW) to monitor availability, dispensing prices and affordability of opioids. We found that opioids with complex delivery mechanisms [fentanyl transdermal (TD) patches, sustained-release (SR) morphine, and SR oxycodone] had lower dispensing prices than immediate-release (IR) morphine formulations. OBJECTIVE: Identify the extent that SR and TD formulations are dispensed at lower prices than generic IR morphine and the possible reasons to explain this observation...

OBJECTIVE: Candida could become the second most frequent cause of nosocomial urinary tract infection. Although Candida albicans is the most important species, others have arisen as emerging pathogens. The aim of this study was to analyze the presence of candiduria in inpatients. METHODS: We performed a retrospective study of Candida isolates from adult inpatient urocultures over five years, gathering and tabulating data on: the species; susceptibility to fluconazole, amphotericin B, and voriconazole (Vitek2, BioMerieux); presence of catheter; hospital department of origin; and patient age and sex...

OBJECTIVES: To observe the effects of Yougui pill (Traditional Chinese Medicine) on the related factors of Wnt signal pathway of rats with knee osteoarthritis (KOA), and explore its protective mechanism. METHODS: Sixty SPF SD rats were randomly divided into the sham-operative group, model group, glucosamine sulfate group, high-dose, middle-dose, low-dose of Yougui pill treated group ( n =10). KOA model was established by modified Hulth method for six weeks. The rats in the high, middle and low-dose of Yougui pill group were treated with Yougui pills at the doses of 20,10 and 5 g/kg respectively by gastrogavage once a day for 8 weeks, while equal volume of normal saline was given to those in the sham and model control group and an equal volume of glucosamine sulfate (1...

High-throughput technologies, offering an unprecedented wealth of quantitative data underlying the makeup of living systems, are changing biology. Notably, the systematic mapping of the relationships between biochemical entities has fueled the rapid development of network biology, offering a suitable framework to describe disease phenotypes and predict potential drug targets. However, our ability to develop accurate dynamical models remains limited, due in part to the limited knowledge of the kinetic parameters underlying these interactions...

Investigations into the development of new therapeutic agents for lung inflammatory disorders have led to the discovery of plant-based alternatives. The rhizomes of Anemarrhena asphodeloides have a long history of use against lung inflammatory disorders in traditional herbal medicine. However, the therapeutic potential of this plant material in animal models of lung inflammation has yet to be evaluated. In the present study, we prepared the alcoholic extract and derived the saponin-enriched fraction from the rhizomes of A...
