Understanding tuberculosis transmission and progression: A prospective cohort study of index cases and close contacts in Moldova.

Objectives: This study aims to determine the progression rate, risk factors and timeline for the progression from exposure to active tuberculosis (TB) in a high-risk population. Using a prospective cohort in the Republic of Moldova, we investigated pulmonary TB disease progression among close contacts of patients with TB in a low-burden country with high rates of drug-resistant TB.

Methods: Close contacts of patients with newly diagnosed TB were recruited and monitored to evaluate for progression rates to active TB.

Age estimation of Arabian mares by incisors morphometry and dentition changes.

Accurate estimation of a horse's age based on the condition of the tooth status is necessary as a scientific and artistic technique, which has not been performed so far in pure Arabian horses of Khuzestan (southern west of Iran). This study aimed to investigate the age-dependent changes in the morphology and morphometry of the incisors in Arabian mares of Khuzestan to estimate age and to compare the estimated dental age and actual age. In this study, 78 Arabian mares of Khuzestan were examined in several equestrian clubs.

The effects of easy goals versus difficult goals on acquisition and retention of a sport skill in children with intellectual disability.

The purpose of the present study was to examine the effects of easy goals versus difficult goals on acquisition and retention of basketball free throws in children with intellectual disability. Twenty-one children with intellectual disability were randomly assigned to an easy goals or difficult goals group. The participants were required to improve their basketball free throws according to their own scores in the previous exercise session.

This study aimed to assess the health-promoting lifestyles of nurses and their association with musculoskeletal disorders and symptoms.

A seroepidemiological survey of infection in referred dogs to Veterinary Hospital of Ahvaz, Iran.

is an intracellular protozoan parasite, which is the cause of toxoplasmosis and can infect a wide variety of warm-blooded animals, including dogs and humans. The present study evaluated the seroprevalence of infection in pet dogs in Ahvaz, southwest city of Iran, and investigated the related possible risk factors. A total of 180 serum samples were collected from dogs referred to Veterinary Hospital of Ahvaz.

Study the effect of crocin in three maternal hypoxia protocols with different oxygen intensities on motor activity and balance in rat offspring.

Hypoxia as one of the most common clinical disturbances in pregnancy period can cause destructive changes in motor sensory cortex and can lead to imperfect organization in motor reactions. Crocin, a water-soluble carotenoid, is the most active ingredients of saffron and a lot of studies declare its positive effectiveness on improving motor activity. Since the hypoxia intensity affects its malicious amount on movement, in this paper, we have studied the effect of crocin in three maternal hypoxia protocols with different oxygen intensities on motor activity and balance in rat offspring.
