REVIEW
David Taylor
This article outlines the historical development of health economics and its present role in oncology related health technology assessments (HTAs). Despite concerns about the prices and immediate costs of new anticancer medicines for indications such as breast cancer overall spending on such treatments is affordable and offers long term value for money in countries such as the US, Canada and those of Western Europe. Oncologists wishing to protect the interests of current and future patients with both advanced and earlier stage cancers may be regarded as having a responsibility to understand the nature of health economic evaluations, and to be actively involved in decisions affecting access to current treatments and future levels of investment in incrementally improving therapies...

Isoxsuprine hydrochloride (vasodilator drug), folic acid and ascorbic acid are medicines which can be utilized alone or simultaneously by pregnant women. In the present work the competitive binding of isoxsuprine hydrochloride (ISO) with human serum albumin (HSA) in the absence and presence of folic acid (FOL) and ascorbic acid (AS) was investigated using different spectroscopic probes and molecular docking studies. The results of fluorescence suggested that isoxsuprine alone or in the presence of ascorbic acid can bind to HSA and quench the fluorescence of HSA with static mechanism but For HSA-folic acid-isoxsuprine system, dynamic type of quenching mechanisms is involved...

BACKGROUND: Ficus carica Linn. (Fc), common fig, has been traditionally used for many metabolic, cardiovasculary, respiratory, gastrointestinal, and skin disorders. Several studies were performed showing its anti-inflammatory, anti-angiogenic, anticancerogenic, and tissue-protective effects. In all of those studies, the positive effects of Fc were concluded as the result of its antioxidant and anti-inflammatory features due to the polyphenols it contains. AIMS: To study the phenolic compounds of Fc extract and to investigate the molecular basis of anti-inflammatory, anti-angiogenic, antimitotic, and anti-androgenic effects of Fc leaf extract in vitro...

The standardised randomised clinical trial (RCT) has been exceedingly popular in medical research, economics, and practical policy making. Recently, RCTs have faced criticism. First, it has been argued by John Worrall that we cannot be certain that our sample is not atypical with regard to possible confounding factors. I will argue that at least in the case of medical research, we know enough about the relevant causal mechanisms to be justified to ignore a number of factors we have good reason not to expect to be disruptive...

BACKGROUND: Blindness caused by soft tissue fillers is an extremely low-probability event, but it results in great concern because of its devastating consequences. Currently, the mechanism of an embolism is usually considered to be an accidental injection of fillers into the blood vessels of the face, such as a facial artery, and then retrograding into the ophthalmic artery system, which causes retinal ischemic necrosis. In addition, previous studies have shown that there are anastomoses between facial arteries and branches of the ophthalmic artery in cadavers...

The causative agent of cholera, Vibrio cholerae, is a public health concern. Multidrug-resistant V. cholerae variants may reduce chemotherapeutic efficacies of severe cholera. We previously reported that the multidrug efflux pump EmrD-3 from V. cholerae confers resistance to multiple structurally distinct antimicrobials. Medicinal plant compounds are potential candidates for EmrD-3 efflux pump modulation. The antibacterial activities of garlic Allium sativum, although poorly understood, predicts that a main bioactive component, allyl sulfide, modulates EmrD-3 efflux...

The variation in the biological function of proteins plays an important role in plasma medicine and sterilization. Several non-thermal plasma sources with different feeding gases are used worldwide for plasma treatment, including dielectric barrier discharge (DBD) and atmospheric-pressure plasma jet (APPJ) as the most commonly used sources. Therefore, in the present work, we used both DBD and APPJ plasma sources with N2 and air as feeding gases to evaluate the effects on the structural, thermodynamic, and activity changes of enzymes...
