in order to evaluate the relationship between the concentration of welding fumes and cigarette smoke on the bronchopulmonary system function, a comparative study of spirometric measurements in 100 welders and 50 healthy volunteers was performed in an automobile manufacturing company. two groups of workers were matched according to their age, height, smoking habit, years of service and social cl...

this study aimed to develop an index that can rank welding workplace that associate well with possible health risk of welders.welding fumes health index (wfhi) were developed based on data from case studies conducted in plant 1 and plant 2. personal sampling of welding fumes to assess the concentration of metal constituents along with series of lung function tests was conducted. fifteen metal c...

In this note, we give some estimate of the generalized quadrature formula of Gauss-Jacobi$$underset{a}{overset{a+eta left( b,aright) }{int }}left( x-aright)^{p}left( a+eta left( b,aright) -xright) ^{q}fleft( xright) dx$$in the cases where $f$ and $left| fright| ^{lambda }$ for $lambda >1$, are $s$-preinvex functions in the second sense.

Introduction: Metabolic syndrome (MetS) and impaired lung functions have been associated with an increased risk for coronary heart disease. The aim of this study was to investigate the pulmonary functions in patients with MetS. Methods: This cross-sectional study included 200 subjects with MetS in the study group and 100 subjects without MetS in the control group. Participants were examined...

Objective(s): Lung cancer is one of the most common malignant tumors, which seriously threatens the health and life of the people. Recently, a novel long non-coding RNA (lncRNA) termed lncFOXO1 was found and investigated in breast cancer. However, the effect of lncFOXO1 on lung cancer is still ambiguous. The current study aimed to uncover the functions of lncFOXO1 in l...

introduction: metabolic syndrome (mets) and impaired lung functions have been associated with an increased risk for coronary heart disease. the aim of this study was to investigate the pulmonary functions in patients with mets. methods: this cross-sectional study included 200 subjects with mets in the study group and 100 subjects without mets in the control group. participants were examined at ...

we present a collocation method to obtain the approximate solutionof troesch's problem which arises in the confinement of a plasmacolumn by radiation pressure and applied physics. by using thechristov rational functions and collocation points, this methodtransforms troesch's problem into a system of nonlinear algebraicequations. the rate of convergence is shown to be exponential. then...

Objective(s): Lung cancer is the main leading cause of cancer death worldwide. Angiogenesis is the main step in proliferation and spreading of tumor cells. Targeting vascular endothelial growth factor (VEGF) is an effective approach for inhibition of cancer angiogenesis. Nanobodies (NBs) are a novel class of antibodies derived from the camel. Unique characteristics of Nbs like their small size ...

Objective: The effects of natural adjuvants were examined on total and differential WBC counts in lung lavage of sensitized guinea pigs. Materials and Methods: In three sensitized groups of guinea pigs including: untreated sensitized animals (S), sensitized animals treated with adjuvant G2 (S+G2) and G2F (S+G2F) as well as non-sensitized group (C) (n=6 for each group), total and differential WB...
