Enantiomer fractions instead of enantiomer ratios
The use of enantiomer ratios (ERs) to indicate the relative amounts of a pair of enantiomers in a sample has some disadvantages. Enantiomer fractions (EFs) are proposed as all alternative expression to eliminate the difficulties. (C) 2000 Elsevier Science Ltd

Changes in circle area after gravity compensation training in chronic stroke patients
After a stroke, many people experience difficulties to selectively activate muscles. As a result many patients move the affected arm in stereotypical patterns. Shoulder abduction is often accompanied by elbow flexion, reducing the ability to extend the elbow. This involuntary coupling reduces the patient's active range of motion. Gravity compensation reduces the activation level of shoulder abductors which limits the amount of coupled elbow flexion. As a result, stroke patients can instantaneously increase their active range of motion [1]. The objective of the present study is to examine whether training in a gravity compensated environment can also lead to an increased range of motion in an unsupported environment.

Кубанська музична фольклористика: етапи становлення
On the basis of materials related to the history of the Ukrainians in Kuban (of 1792) the author determines that priests, historians, ethnographers, students of local lore, regents, choirmasters, teachers and poets were at the beginnings of Kuban musical study of folklore. The formation of Kuban musical folklore had 3 stages: concert and representational stage (of 1818), stage of collection (of 1865), transcriptional and publishing stage. Bihday, Kontsevych, Zakharchenko and Koshyts made the most considerable contribution in development of this science. The author of the article gives detailed information about their biographies

Cross-cultural adaptation and validation of the Dutch version of the High Activity Arthroplasty Score
Introduction: The high Activity Arthroplasty Score ( hAAS) has been designed to differentiate in the functional ability between normal and more active patients after total knee arthroplasty (TKA) and total hip arthroplasty (T hA). no such questionnaire is currently available in the Dutch language. The objective of this study was to evaluate the Dutch version of the hAAS in ThA and TKA patients. Patients & Methods: The forward and backward translated Dutch version of the hAAS combined with the national Dutch patient reported outcome measures (PR oMS) were sent to two hundred patients of all ages who underwent TKA or T hA. The internal consistency, construct validity and ceiling/floor effects of the hAAS were evaluated. Results: 108 patients (51 ThA and 57 TKA) participated in this study. A good internal consistency with a Cronbach’s alpha of 0.78, 0.81 and 0.84 was found in all patients, the Th A and the TKA group respectively. Significant positive correla- tions were observed between the hAAS and VAS Qo l, EQ-5D, all K oo S sub-scores except the symptoms score, and all hoo S sub-scores except the Qo l score. A negative correlation was found with the VAS pain. no ceiling or floor effect was seen in the hAAS. Discussion: The Dutch version of the hAAS can be used to evaluate the functional ability in more active patients of all ages who underwent ThA or TKA with an acceptable internal consistency and construct validity, with no ceiling or floor effects
Major surgery within the first 3 months of life and subsequent biobehavioral pain responses to immunization at later age: A case comparison study. [IF 3.4]
Objectives. Pain exposure during early infancy affects the pain perception beyond infancy into childhood. The objective of this study was to examine whether major surgery within the first 3 months of life in combination with preemptive analgesia alters pain responses to immunization at 14 or 45 months and to assess whether these alterations are greater in toddlers with a larger number of negative hospital experiences. Methods. Two groups of 50 toddlers each were compared: index group and control group. All index toddlers had participated within the first 3 months of their life in a randomized, clinical trial that evaluated the efficacy of preemptive morphine administration for postoperative analgesia. The controls were matched by type of immunization and community health care pediatrician. Pain reactions were recorded at routine immunization at either 14 (measles-mumps-rubella immunization) or 45 months (diphtheria-tetanus-trivalent polio immunization) of age. Outcome measures were facial reaction, coded by the Maximum Discriminative Facial Movement Coding System; heart rate (HR); and cortisol saliva concentration. Negative hospital experiences included number of operations requiring postoperative morphine administration, cumulative Therapeutic Intervention Scoring System scores, and length of stay in the intensive care unit or total hospitalization days. Results. No differences were found between the index and control groups in the facial display of pain, anger, or sadness or in physiologic parameters such as HR and cortisol concentrations. Intragroup analyses of the index group showed that after measles-mumps-rubella vaccination, the number of negative hospital experiences correlated positively with the facial responsiveness and negatively with HR responses. No effect was seen after diphtheria-tetanus-trivalent polio immunization. Conclusions. Major surgery in combination with preemptive analgesia within the first months of life does not alter pain response to subsequent pain exposure in childhood. Greater exposure to early hospitalization influences the pain responses after prolonged time. These responses, however, diminish after a prolonged period of nonexposure
