Municipal solid waste recycling: Impacts on energy savings and air pollution.

In recent years, recycling of municipal solid waste (MSW) has been recognized as one of the most efficient methods of waste management in terms of environmental benefits. This study investigates the energy savings and other environmental benefits of recycling of dry MSW collected in Shiraz, Iran (2018). The impact of different recycling rates (current = 15%, desirable = 50%, ideal = 80%) on environmental benefits and energy savings were assessed.

Sugarcane molasses enhances TGF-β secretion and FOXP3 gene expression by Bifidobacterium Animalis Subsp. Lactis stimulated PBMCs of Ulcerative Colitis patients.

Ulcerative colitis (UC) is one of the inflammatory diseases of the gut with frequent bloody diarrhea leads to increased rates of anemia. Evidences indicate the immunomodulation disorders in the response to intestinal microbiota in UC. Although sugarcane molasses, rich in necessary minerals and vitamins, could be a good support nutrient but its effect on immune system of UC patients is unknown.

A case study of BTEX characteristics and health effects by major point sources of pollution during winter in Iran.

This study characterized spatio-temporal variations in the concentration of benzene, toluene, ethylbenzene, and xylene (BTEX) compounds in the vicinity of gas and compressed natural gas (CNG) stations in Tehran, Iran. Health risk assessment (HRA) was computed using Monte Carlo simulations (MCS) for evaluating inhalation lifetime cancer risk (LTCR), the hazard quotient (HQ), and sensitivity analysis (SA) for BTEX exposure in different age groups (birth to <81) and as a function of distance (0-250 m) from the center of the stations. For all monitoring stations, the average values of benzene, toluene, ethylbenzene, and xylene in winter were 466.

Data on spot-kits versus titration method for iodine determination in salt: Performance and validity.

The aim of this data is comparison of achieved data from salt iodine measurement by titration method with using sodium thiosulfate in presence of lugol׳s reagent and commercial spot- kit. Titration measurement was carried out in two different laboratories using standard samples. 437 samples including 20 commercial brands were collected throughout Iran.

In-vitro effects of Mycobacterium bovis BCG-lysate and its derived heat shock proteins on cytokines secretion by blood mononuclear cells of rheumatoid arthritis patients in comparison with healthy controls.

Background: Several studies have shown that heat shock protein (HSP)-reactive T cells have an immunoregulatory phenotype indicating that HSPs are able to trigger immunoregulatory pathways, which can suppress immune responses that occur in human inflammatory diseases, such as rheumatoid arthritis (RA). Mycobacterium bovis strain Bacillus Calmette-Guérin (BCG) is rich of HSPs which could be good resources of these regulatory proteins for modulation of immune response.

Purposes: To study the effects of BCG-lysate and BCG-derived HSPs on secretion of T regulatory cytokines by PBMCs of RA patients in comparison with healthy controls.

Positional relationship between natural killer cells and distribution of sympathetic nerves in decidualized mouse uterus.

Background: Uterine natural killer (uNK) cells are the most abundant leukocytes in pre-implantation endometrium and early pregnancy deciduas in humans and rodents. They are associated with structural changes in maternal spiral arteries but regulation of their recruitment and activation is incompletely understood. The major subpopulation of uNK cells in humans expresses CD56, the neural cell adhesion molecule (NCAM)-1 while their counterpart in mouse expresses asialoGM1, a brain ganglioside.

Investigation and evaluation of ultrasound reactor for reduction of fungi from sewage.

The objective of the investigation was to study the application of ultrasound reactor technology (USRT) as a disinfectant for reduction of fungi from sewage effluent. Fungi are carbon heterotrophs that require preformed organic compounds as carbon sources. USRT is an attractive means to improve water quality because of the system simplicity and no production of toxic by-products.
