Introducing heterotrophic iron ore bacteria as new candidates in promoting the recovery of e-waste strategic metals.

Electrical instruments are an integral part of human life resulting in a vast electronic waste generation (74.7 Mt by 2030), threatening human life and the environment due to its hazardous nature. Therefore, proper e-waste management is a necessity.

Remediation of metals and plastic from e-waste by iron mine indigenous acidophilic bacteria.

The growing consumption of electrical and electronic equipment leads to high amounts of electronic waste (e-waste), which is now considered the fastest-growing waste stream at the national and international levels. As well as being a potential secondary resource due to its precious metals content, e-waste also contains strategic metals and plastics. For instance, mobile phones have about 25-55% plastic substances.

Indigenous bacteria as an alternative for promoting recycled paper and cardboard mill wastewater treatment.

The present study aimed to investigate indigenous bacteria possibility in recycled paper and cardboard mill (RPCM) wastewater treatment through the isolation and identification of full-scale RPCM indigenous bacteria. The molecular characterization of the isolated bacteria was performed by 16S rRNA gene sequencing. Klebsiella pneumoniae AT-1 (MZ599583), Citrobacter freundii AT-4 (OK178569), and Bacillus subtilis AT-5 (MZ323975) were dominant strains used for RPCM wastewater bioremediation experiments.

Data on airborne bacteria and fungi emission from a conventional hospital wastewater treatment plant.

The lack of necessary air pollution control measures in the construction of hospital wastewater treatment plants results in the release of harmful bioaerosols in and around the hospital. A sampling of airborne bacteria and fungi was performed using the gravitational method in 9 sites including an upwind site, intra-plant and outside a hospital wastewater treatment plants with activated sludge technology in Tehran (1, 5 and 3 points, respectively) from March to June. Bioaerosol on nutrient agar media were identified quantitatively and qualitatively.

Budget Impact Analysis of Rotavirus Vaccine Adoption in the Childhood Immunization Schedule of Iran.

Objectives: To examine the budget impact of introducing the RotaTeq® vaccine (Merck and Co Inc, West Point, PA) to the national immunization program in Iran.

Methods: The pre- and postvaccine introduction costs were compared. The total annual costs included the vaccination and diarrhea treatment costs.

Data on biosurfactant assisted removal of TNT from contaminated soil.

Contamination of environment, especially soil, is in great concern and can cause health problems. Thus, remediation of these pollutants through environmentally friendly methods should be considered. The aim of this data was bioremediation of TNT from contaminated soil.

Kinetic parameters and nitrate, nitrite changes in bioremediation of Toxic Pentaerythritol Tetranitrate (PETN) contaminated soil.

Background: Cleanup of areas contaminated by explosives is a public health concern. Some explosives can be carcinogenic in humans. Pentaerythritol Tetranitrate (PETN), a powerful explosive with very low water solubility, can be easily transported to ground waters.

Budget impact analysis of vaccination against Haemophilus influenzae type b as a part of a Pentavalent vaccine in the childhood immunization schedule of Iran.

Background: Health decision makers need to know the impact of the development of a new intervention on the public health and health care costs so that they can plan for economic and financial objectives. The aim of this study was to determine the budget impact of adding Haemophilus influenzae type b (Hib) as a part of a Pentavalent vaccine (Hib-HBV-DTP) to the national childhood immunization schedule of Iran.

Methods: An excel-based model was developed to determine the costs of including the Pentavalent vaccine in the national immunization program (NIP), comparing the present schedule with the previous one (including separate DTP and hepatitis B vaccines).

Features and application of wearable biosensors in medical care.

One of the new technologies in the field of health is wearable biosensor, which provides vital signs monitoring of patients, athletes, premature infants, children, psychiatric patients, people who need long-term care, elderly, and people in impassable regions far from health and medical services. The aim of this study was to explain features and applications of wearable biosensors in medical services. This was a narrative review study that done in 2015.

Stability of changes in mandibular intermolar and intercuspid distances following orthodontic treatment.

Background: The aim of this study was to determine the pattern and amount of change exhibited in mandibular intercanine and intermolar width during treatment and assessing its stability1-3 years post-retention.

Materials And Methods: The material consisted of 70 cases of which 20 cases were treated without extraction and 30 cases were treated with extraction, which were compared with 20 untreated cases which served as a control group. A series of three measurements were made for each case of the treated group: At the beginning of treatment, end of active treatment and 1-3 years post-retention; and for the control group: At 12, 15 and 18 years of age.

Efficacy and side effects of dacarbazine in comparison with temozolomide in the treatment of malignant melanoma: a meta-analysis consisting of 1314 patients.

The widespread prevalence of melanoma, one of the most malignant forms of skin cancer, is increasing rapidly. Two chemotherapeutic regimens are commonly used for the palliative treatment of malignant melanoma: intravenous administration of single-agent dacarbazine or oral administration of temozolomide. The aim of this study was to compare the effectiveness and side effects of dacarbazine with those of temozolomide through a meta-analysis.

Alteration of hepatic cells glucose metabolism as a non-cholinergic detoxication mechanism in counteracting diazinon-induced oxidative stress.

The aim of this study was to evaluate effects of acute exposure to various doses of diazinon, a widely used synthetic organophosphorus (OP) insecticide on plasma glucose, hepatic cells key enzymes of glycogenolysis and gluconeogenesis, and oxidative stress in rats. Diazinon was administered by gavage at doses of 15, 30 and 60 mg/ kg. The liver was perfused and removed under anaesthesia.

Protection by pentoxifylline of diazinon-induced toxic stress in rat liver and muscle.

ABSTRACT The effects of diazinon, pentoxifylline, and their combination therapy on plasma glucose, the key enzymes of glycogenolysis and gluconeogenesis, and oxidative stress were studied in rat liver and muscle. Oxidative stress was determined by measuring the concentration of lipid peroxides and assessing total antioxidant capacity. Diazinon (60 mg/kg) and pentoxifylline (100 mg/kg) were administrated by gavage.

Surgery of acute type A dissection: what have we learned during the past 25 years?

Every acute dissection involving the ascending aorta (Stanford type A) must undergo emergency surgical repair. However, the surgical techniques must vary according to the clinical presentation of the patients or the anatomical patterns observed. Furthermore, surgery is generally difficult because of the poor condition of the aortic tissues.
