Small bowel adenocarcinoma (SBA) is an aggressive disease with limited treatment options. Despite previous studies, its molecular genetic background has remained somewhat elusive. To comprehensively characterize the mutational landscape of this tumor type, and to identify possible targets of treatment, we conducted the first large exome sequencing study on a population-based set of SBA samples ...

Many human tumors, such as those of the breast, metastasize initially via the lymphatics. The tumor cell surface is believed to play a critical role in this process. To study the cell surface properties involved in dissemination, the poorly metastasizing R3230AC rat mammary adenocarcinoma was enriched for metastasizing cells by excising rare lymph node metastases arising after the s.c. injectio...

BACKGROUND The use of maternal health care is limited in India despite several programmatic efforts for its improvement since the late 1980's. The use of maternal health care is typically patterned on socioeconomic and cultural contours. However, there is no clear perspective about how socioeconomic differences over time have contributed towards the use of maternal health care in India. METHO...

Timed token networks such as FDDI networks has been widely deployed to support synchronous traffic. However the medium access control (MAC) protocol of FDDI allows transmission of synchronous messages up to at most one half of the total bandwidth of the network. Shin and Zheng has proposed a modification to the FDDI MAC protocol, called FDDI-M, which can double a ring’s ability in supporting sy...

Spina bifida aperta (SBA), one of the most common congenital malformations, causes lifelong neurological complications, particularly in terms of motor dysfunction. Fetuses with SBA exhibit voluntary leg movements in utero and during early neonatal life, but these disappear within the first few weeks after birth. However, the pathophysiological sequence underlying such motor dysfunction remains ...

In this study surface modified SBA-15, coated with octadecyltrichlorosilane (C18), is considered as an alternative adsorbent for metal ions in water. The SBA-C18 was loaded with Bis(2,4,4-trimethylpentyl) phosphinic acid (cyanex 272) as the metal ion extractant. The adsorption characteristics of phosphinic acid loaded SBA-C18 were evaluated for Cu(II) and Zn(II) ions in aqueous solution. Adsorp...

The utilization rate of maternal services remains low in sub-Saharan Africa and may be contributing to the region's high maternal mortality rate. This study examines the influence of antenatal care (ANC) on skilled birth attendance (SBA) in Nigeria. The data used were collected from a nationally representative sample of women (aged 15-49) in 2011. The sample is restricted to women who were with...

Sheep blood agar containing 23.75 microgram of sulfamethoxazole and 1.25 microgram of trimethoprim (SXT-BA) per ml was compared with conventional sheep blood agar (SBA) for isolating group A and B streptococci from throat cultures. This selective medium allowed much better recovery of group A and B streptococci and suppressed the growth of the normal flora, including "viridans" streptococci. In...

Numerous methods have been proposed to integrate real-time and non-real-time services of the timed-token medium access control (MAC) protocol. One of the key issues in tailoring the timed-token protocol for real-time applications is the synchronous band-width allocation (SBA) problem whose objective is to meet both the protocol and deadline constraints. Several non-optimal local SBA schemes and...

grinding (solvent-free) method was used as a superior technique to prepare mesoporous photocatalysts of zno, zns, zno / zns, cdo, cds and cdo / cds-sba-15. in this technique, the nitrate, acetate and chloride salts of zinc and/or cadmium were grinded with as-synthesized sba-15 as a mesoporous material. the controllable sulfurationis was used to prepare zns, zno/zns, cds and cdo/cds-sba-15 at te...
