Measurement of black carbon (BC) was carried out at Syowa station Antarctica (69 • S, 39 • E) from February 2004 until January 2007. The BC concentration at Syowa ranged from below detection to 176 ng m −3 during the measurements. Higher BC concentrations were observed mostly under strong wind (blizzard) conditions due to the approach 5 of a cyclone and blocking event. The BC-rich air masses tr...

Black carbon (BC) may play an important role in the global C budget, due to its potential to act as a significant sink of atmospheric CO2. In order to fully evaluate the influence of BC on the global C cycle, an understanding of the stability of BC is required. The biochemical stability of BC was assessed in a chronosequence of high-BC-containing Anthrosols from the central Amazon, Brazil, usin...

Reduced susceptibility of Listeria monocytogenes to benzalkonium chloride (BC), a quaternary ammonium compound widely used in food processing and hospital environments, is a growing public health and food safety concern. The minimal inhibitory concentration of BC on 392 L. monocytogenes strains from Switzerland (CH) and Finland (FIN) was determined. Within this strain collection, benzalkonium c...

Background: Due to the incidence and recurrence of bladder cancer (BC), it could be categorized as a clinical and social problem that often occurs at an advanced age. This study was designed to determine the incidence of BC in Isfahan, Iran. Methods: A retrospective descriptive survey of information based on bladder cancer (ICD-O, third edition; C67) was obtained from the Isfahan Deputy of Hea...

Caveolin-1(CAV-1) was demonstrated to be a tumor suppressor gene and be implicated in the development of breast cancer (BC). Numerous potentially functional polymorphisms in CAV-1 have been identified, but their effects on BC were not clear. This case-control study aims to evaluate the relationship between CAV-1 polymorphisms and BC risk. 560 BC patients and 583 healthy controls were enrolled i...

OBJECTIVE The purpose of this study was to evaluate the effectiveness of focused appendicitis ultrasound combined with Alvarado score to accurately identify appendicitis in children in whom it is suspected, thereby reducing unnecessary CT examinations and associated radiation exposure. MATERIALS AND METHODS We retrospectively evaluated the focused appendicitis ultrasound, CT, clinical, and la...

We measured black carbon (BC) in ultrafiltered, high–molecular weight dissolved organic matter (UDOM) in surface waters of Delaware Bay, Chesapeake Bay, and the adjacent Atlantic Ocean (U.S.A.) to investigate the importance of riverine and estuarine dissolved organic matter (DOM) as a source of BC to the ocean. BC was 5– 72% of UDOM-C (27 6 17%), which corresponds to 8.9 6 6.5% of dissolved org...

background: this study aims to demonstrate the frequency of malignant breast cancer (bc) according to pathologic findings in birjand during 2011-2013 years. methods: for this cross-sectional study, the sample consisted of pathologic records from 229 breast biopsies of two hospitals in birjand. results: most of the biopsies in women were malignant cases which nearly 90% of them were detected aft...

With a homogenization-evaporation method, β-carotene (BC) loaded nanoparticles were prepared with different ratios of food-grade sodium caseinate (SC), whey protein isolate (WPI), or soy protein isolate (SPI) to BC and evaluated for their physiochemical stability, in vitro cytotoxicity, and cellular uptake by Caco-2 cells. The particle diameters of the BC loaded nanoparticles with 0.75% SC or 1...

Women from ethnic minority groups, including immigrants and refugees are reported to have low breast cancer (BC) screening rates. Active, culturally-sensitive outreach is vital for increasing participation of these women in BC screening programs. Women at high BC risk and who belong to an ethnic minority group are of special concern. Such women could benefit from ongoing trials aimed at optimiz...
