Risk of venous thromboembolic disease in postmenopausal women taking oral or transdermal hormone replacement therapy

Objective  

The influence of hormone replacement therapy (HRT) on hemostasis processes depends on the type of hormone, the combination of doses, the time of taking HRT, and the route of administration (oral, transdermal, implanted). The aim of the current study was to assess some parameters of coagulation, especially tissue factor pathway inhibitor (TFPI) and tissue factor (TF) in postmenopausal women using oral or transdermal HRT.     

Using sexually explicit material in a therapeutic context

For most of us, sex is a subjective, lived experience that is as unique as our genetic make-up, our upbringing, our thoughts, values, feelings, beliefs and ideas. It is through our erotic interactions, or the absence thereof, that we form aspects of our fluid and mutable erotic paths and identities. Despite the proliferation of sexual imagery throughout our culture, many of us still struggle with what sex means to us, what we do, how we experience it and what that says about who we are as people. Some who struggle with this may seek the services of a psychosexual sex therapist. This paper aims to explain how such services function, why they are necessary and how the use of sexually explicit material, in some psychosexual therapeutic contexts, can help unravel the mixed responses we have to sex and our social conditioning, and enhance our overall relationship to eroticism, pleasure and general well-being.     

False negativity to carbohydrate-deficient transferrin and drugs: a clinical case

Introduction:

In this work we report on the possible effect of the medical therapy on CDT concentration in a chronic alcohol abuser, with known medical history (July 2007 – April 2012) and alcohol abuse confirmed by relatives.

Case history:

At the end of 2007, patient displayed the following laboratory results: AST 137 U/L, ALT 120 U/L, GGT 434 U/L, MCV 101 fL and CDT 3.3%. On December 2007, after double coronary artery bypass surgery, he began a pharmacological treatment with amlodipine, perindopril, atorvastatin, isosorbide mononitrate, carvedilol, ticlopidine and pantoprazole. In the next months, until may 2011, the patient resumed alcohol abuse, as confirmed by relatives; however, CDT values were repeatedly found negative (0.8% and 1.1%) despite elevated transaminases and GGT, concurrent elevated ethyl glucuronide concentration (> 50 mg/L) and blood alcohol concentration (> 1 g/L). Alcohol consumption still continued despite increasing disulfiram doses ordered by an Alcohol Rehab Center. On May 2011, the patient was transferred to a private medical center where he currently lives.

Conclusions:

This study suggests the possibility that a medical therapy including different drugs may hamper the identification of chronic alcohol abusers by CDT.

纳米TiO_2催化超声降解染料工业废水的研究

采用纳米TiO2为催化剂,超声辐照为主要手段对实际印染工业废水进行了降解实验研究,考察了各种反应参数对印染废水降解效果的影响。结果表明,纳米TiO2对印染工业废水的超声降解效果具有明显的辅助和提高。当超声波频率为45kHz,功率为200W,溶液初始pH值为2.63,超声反应时间为150min的条件下,印染工业废水的COD去除率为73%,而同样条件下,投加750mg/L纳米TiO2,其超声降解废水COD去除率可达90.2%。     

Human biochemical genetics： an insight into inborn errors of metabolism

Inborn errors of metabolism （IEM） include a broad spectrum of defects of various gene products that affect intermediary metabolism in the body. Studying the molecular and biochemical mechanisms of those inherited disorder, systematically summarizing the disease phenotype and natural history, providing diagnostic rationale and methodology and treatment strategy comprise the context of human biochemical genetics. This session focused on： （1） manifestations of representative metabolic disorders; （2） the emergent technology and application of newborn screening of metabolic disorders using tandem mass spectrometry; （3） principles of managing IEM; （4） the concept of carrier testing aiming prevention. Early detection of patients with IEM allows early intervention and more options for treatment.
