Q Fever Endocarditis in Iran.

Patients with the underlying valvular heart disease are at the high risk of developing sub-acute or chronic endocarditis secondary to Coxiella burnetii. Q fever endocarditis is the most common manifestation along with persistent the infection. There is some serologic and molecular evidence of C.

The effect of hormone therapy on bone mineral density and cardiovascular factors among Iranian female athletes with amenorrhea/oligomenorrhea: A randomized clinical trial.

Functional hypothalamic menstrual disorder (FHMD) has a destructive effect on the athlete's bone mineral density and cardiovascular system. Utilizing hormone replacement therapy to treat FHMD in athletes is controversial. This study was conducted to examine the effect of hormone therapy on bone density and the cardiovascular system of professional female athletes with FHMD.

The Effect of Increasing Volume of Exercise on Activation Pattern of Vastus Medialis and Lateralis and its Correlation With Anterior Knee Pain in Karate Elites.

Background: The effects of exercise volume on the pattern of muscle activity is one of the most important factors in training management and injury risk reduction. In the lower limb, the quadriceps muscle which plays a determining role in performing the stance and other karate techniques could be injured in intensive exercise and may induce anterior knee pain in athletes.

Objectives: The aim of this study was to determine the relationship between training volume and muscle activity of vastus medialis and vastus lateralis and its association with anterior knee pain in karate elites.

Platelet activation and function in response to high intensity interval exercise and moderate continuous exercise in CABG and PCI patients.

Background: The effects of high intensity interval training (HIIT) on inflammatory markers and endothelial function have been extensively shown. However, the acute effect of HIIT on platelet activation and function in patients with recent revascularization is unclear.

Objective: The purpose of present study was to compare the responses of platelet activation (CD62P) and function (platelet aggregation) to high intensity interval exercise (HIIE) and moderate continuous exercise (MCE) in coronary artery bypass grafting (CABG) and percutaneous coronary interventions (PCI) patients.

Sport Injuries of Karate During Training: An Epidemiologic Study in Iran.

Background: Karate is a public sport that has athletes in various age ranges and abundant active sport clubs in Iran. The pattern of injury in this sport in Iranian athletes seems different from other countries.

Objectives: This study was performed with the purpose of considering the incidence and type of injury of karate athletes aged below 30 years from Tehran, Iran clubs.

The study of correlation between forward head posture and neck pain in Iranian office workers.

Introduction: Factors such as prolonged sitting at work or improper posture of head during work may have a great role in neck pain occurrence among office employees, particularly among those who work with computers. Although some studies claim a significant difference in head posture between patients and pain-free participants, in literature the forward head posture (FHP) has not always been associated with neck pain. Since head, cervical and thoracic postures and their relation with neck pain has not been studied in Iranian office employees, the purpose of this study was to investigate the relationship between some work-related and individual factors, such as poor posture, with neck pain in the office employees.

Assessment of Correlation between Electrogoniometer Measurements and Sports-Specific Movement in Karate Elites.

Purpose: To examine the intra-rater reliability of knee movement data in sagital plane obtained from electrogoniometer (EGM) in a basic, sport-specific task of karate.

Methods: A total of 23 elite karate athletes (13 females and 10 males; mean age of 16.10±1.

The relationship of forward head posture and rounded shoulders with neck pain in Iranian office workers.

Unlabelled: Background Office workers spend a long period of time behind a computer during working hours. The relation between the posture of sitting during work with computer and neck pain is still debatable. Even though some researchers claim a significant difference in head posture between patients with neck pain and pain-free participants, the FHP (forward head posture) has not always been associated with neck pain in literature.

An 18-month Follow-up of Anger in Female Karate Athletes.

Objective: The aim of this study was to evaluate changes of anger scores in female karate athletes during 18 months, and to compare anger scores in adolescents who continue or stop training karate.

Method: The sample consisted of 18 female elite karate athletes, practicing modern style of karate. To measure anger and its subscales, participants were asked to complete "Adolescent Anger Rating Scale" (AARS) questionnaire in both stages of the study.

Anger in Adolescent Boy Athletes: a Comparison among Judo, Karate, Swimming and Non Athletes.

Objective: Karate and judo are originally Japanese martial arts which may have different influences on adolescents' behavior. This study was conducted to examine the total anger rate and its subscale-reactive anger, instrumental anger, and anger control-rates in young karateka and judoka.

Methods: A cross-sectional study was carried out in 11 to 19-year old boys.

Bone Mineral Changes and Cardiovascular Effects among Female Athletes with Chronic Menstrual Dysfunction.

Purpose: Oligo/amenorrhea, as a part of the Female Athlete Triad has adverse effects on the athlete's bone mineral density (BMD) and cardiovascular system. Hypoestrogenism, due to suppression of hypothalamus-pituitary axis (HPA) as a result of energy imbalance, is the possible cause of the Triad. This study was designed based on following up and reassessment of elite female athletes who were diagnosed as menstrual dysfunction about two years ago.

An analysis of anger in adolescent girls who practice the martial arts.

The effect of martial arts on adolescents' behavior, especially aggression, is controversial. The aim of this study was to assess and compare anger ratings among adolescent girl athletes of different martial arts. 291 female adolescents between the ages of 11 and 19 were assessed according to the Adolescent Anger Rating Scale designed by DM Burney.
