BACKGROUND: Premenopausal women undergoing chemotherapy are at high risk for premature ovarian failure and its long-term consequences. Data on potential markers to evaluate ovarian reserve pre- and posttreatment are limited. Anti-Müllerian hormone (AMH) known for ovarian reserve in reproductive medicine could be a surrogate marker and was assessed in premenopausal breast cancer patients of the SUCCESS A study (EUDRA-CT no. 2005-000490-21). METHODS: We identified 170 premenopausal patients, age ≤ 40 years at trial entry, who received FEC-Doc as taxane-anthracylince based chemotherapy...

Thomas Rost, Nicole Kalberer, Eva Scheurer
Infrared photography is interesting for a use in forensic science and forensic medicine since it reveals findings that normally are almost invisible to the human eye. Originally, infrared photography has been made possible by the placement of an infrared light transmission filter screwed in front of the camera objective lens. However, this set-up is associated with many drawbacks such as the loss of the autofocus function, the need of an external infrared source, and long exposure times which make the use of a tripod necessary...

Cytochrome P450 oxidoreductase (POR) has played a potential role in the metabolism of drugs and steroids by supplying electrons to microsomal cytochrome P450 (CYP) enzymes. More than 200 different POR mutations and polymorphisms causing more than 130 amino acid changes in the POR protein have been reported since 2004. A503V is a common amino acid sequence variant encoded by POR*28, whereas A287P and R457H are the most common disease-causing mutations in Europeans and Asians, respectively. Polymorphisms in the POR gene can affect POR activity, CYP-mediated drug metabolism activities, and the efficacy of several clinically used drugs...

OBJECTIVES: Substance use screening is a recommended component of routine healthcare for adolescents. A 2008 survey of Massachusetts primary care physicians found high rates of screening, but low rates of validated tool use, leading to the concern that physicians may be missing substance use-related problems and disorders. In an effort to improve practice, a cross-disciplinary group developed and distributed an adolescent screening, brief intervention, and referral to treatment toolkit in 2009...

OBJECTIVE: The aim of this contribution is to demonstrate how the component structure of a complex intervention (CI) can be efficiently exploited for study design and statistical analysis by using concepts of factorial designs. Many studies on CIs in complementary and alternative medicine exhibit the structure of factorial designs, where all possible combinations of the levels of two or more treatments occur together. In this contribution, the treatment arms of CI studies are explicitly viewed as factorial combinations of their components...

INTRODUCTION: The possibility of sustaining life functions makes it difficult to distinguish between a dying patient and a patient with chances of survival, raising a dilemma for everyone around them. On the one side, continuing with life support techniques that would only extend an irreversible process and result in physical and psychological damage and harm their dignity. On the other side, withholding or withdrawing life support without an adequate reflection and diagnostic-therapeutic effort which may lead to the death of a potentially recoverable child...

Although first-line antidepressants offer therapeutic benefit, about 35% of depressed patients are not adequately treated, creating a large unmet medical need. These medicines mostly enhance the synaptic levels of serotonin and/or norepinephrine. Evidence from preclinical and clinical studies implicate dopamine hypofunction in the pathophysiology of depression. Triple reuptake inhibitors (TRIs), which elevate dopamine in addition to serotonin and norepinephrine, may demonstrate greater efficacy, with the reversal of anhedonia and improved tolerability...

The considerable advances that have been made in the development of organotypic cultures have failed to overcome the challenges of expressing tissue-specific functions and complexities, especially for organs that require multitasking and complex biological processes, such as the liver. Primary liver cells are ideal biological building blocks for functional organotypic reconstruction, but are limited by their rapid loss of physiological integrity in vitro. Here the concept of lattice growth used in material science is applied to develop a tissue incubator, which provides physiological cues and controls the 3D assembly of primary cells...

Plant tannins are a unique class of polyphenols with relatively high molecular weights. Within the ellagitannins group, agrimoniin--dimeric ellagitannin--is one of the most representative compounds found in many plant materials belonging to the Rosaceae family. Agrimoniin was first isolated in 1982 from roots of Agrimonia pilosa Ledeb. (Rosaceae), a plant traditionally used in Japan and China as an antidiarrheal, hemostatic, and antiparasitic agent. Agrimoniin is a constituent of medicinal plants, which are often applied orally in the form of infusions, decoctions, or tinctures...

Drug resistance is an obstacle to chemotherapy in tumor patients. Recent studies have shown that the high stemness of cancer cells may be induced by chemotherapeutic drugs, which is correlated with drug resistance. In the present study, we investigated the effects of bufalin on the stemness of colorectal cancer. We found that cisplatin could induce high stemness through the tumorsphere formation assay in vitro and in vivo in the colorectal cancer cell lines HCT116 and LoVo. In addition, cisplatin-treated tumorsphere cells showed drug‑resistant properties...
