s: Background & objectives: Occupational health hazards are one of the leading causes of deaths worldwide. Food industry workers are at increased risk of chronic lung disease with prolonged exposure. The present cross sectional study was aimed at finding effects of food dust on pulmonary functions working in food industry. Methods: The present cross sectional study was conducted in McCain food ...

The 375 bp fragment of gag gene encoding fragment of matrix protein p16 of ten field isolates of maedi-visna virus (MVV) was amplified; and all the sequences were subsequently subjected to sequencing and genetic analysis. Among isolates, the homologies ranged from 87.2% to 100% and 88% to 100% at the nucleotide and amino acid level, respectively. Polish strains were more related to ovine protot...

Maedi-visna virus (MVV) is a lentivirus of sheep causing chronic inflammatory disease of the lungs (maedi) and the nervous system (visna). We have previously shown that a duplicated sequence in the long terminal repeat (LTR) of MVV is a determinant of cell tropism. Here, we demonstrate that deletion of a CAAAT sequence from either one of the repeats resulted in poor virus growth in sheep choroi...

Vital capacity (VC), forced expiratory volume in 1 s (FEV(1)), peak expiratory flow (PEF), mean forced expiratory flow (FEV(25-75)), and maximum voluntary volume (MVV) were measured in 36 girls and 36 boys with hearing loss and compared with the same number of normal healthy children, all subjects were aged 10-16 years. They participated in an exercise test to calculate VO(2 max) in order to de...

To evaluate the frequency ofthe causes ofexercise limitation in patients with chronic pulmonary disease and to assess the relationship between the resting pulmonary functional parameters and the degree of exercise dyspnea, we reviewed the data from 88 consecutive stable patients with chronic lung disease (62 COPD, 16 interstitial lung disease [ILD]). In each patient, the intensity of dyspnea wa...

The early stages of lentivirus infection of dendritic cells have been studied in an in vivo model. Maedi-visna virus (MVV) is a natural pathogen of sheep with a tropism for macrophages, but the infection of dendritic cells has not been proven, largely because of the difficulties of definitively distinguishing the two cell types. Afferent lymphatic dendritic cells from sheep have been phenotypic...

A multi-view video (MVV) transcoder has been designed. The objective is to deliver maximum quality 3D video data from the source to the 2D video destination, through a wireless communication channel using all of its available bandwidth. This design makes use of the spatial and view downscaling algorithm. The method involves the reuse of motion information obtained from both the reference frames...

COMMUNICATIONS TO THE EDITOR 815 23.0 percent and 8/56 or 14.2 percent respectively. It would be of great interest to further subc!assify these four groups (UAT and NUAT, with and without complications) according to their preoperative FEF25-75%. Important information; with predictive value, might emerge. The authors chose not to include the forced expiratory volume for one second (FEY1) in thei...

Lentiviruses (LV) are nononcogenic viruses, belonging to the Lentivirinae subfamily. The name comes from the Latin word “lenti”, meaning “slow”. According to the definition of B. Sigurdsson, they are causing infections in a limited number of hosts with a long incubation period (months and years) and progressive course, accompanied by damage in definite organs/tissues and a lethal outcome (Sigur...
