Min Lee, Soon Chul Kim
RATIONALE FOR THIS CASE REPORT: Many children are hospitalized because of foreign body ingestion. In such circumstances, the gastroenterologist must consider the timing of ingestion; the size, type, and location of the object ingested; and the patient's symptoms. But appendiceal foreign body in infant is very rare. PATIENT CONCERNS: A 12-month-old boy visited because of swallowing small objects 2 weeks ago. Three small beads were found in the right lower quadrant on abdominal radiography...

PURPOSE: In oncology, RCTs are often beset by slow recruitment, limited generalizability, and strong preferences for interventions by patients and physicians. The cohort multiple randomized controlled trial (cmRCT) is an innovative design with the potential to overcome those challenges. In cmRCT, a prospective cohort serves as an infrastructure for multiple RCTs. We implemented cmRCT in a clinical breast cancer setting by creating UMBRELLA-a large prospective cohort of breast cancer and DCIS patients/survivors...

A calibration coefficient R (= DA/DE) for photons was employed to characterize the photon dose in radiobiological experiments, where DA was the actual dose delivered to cells and DE was the dose recorded by an ionization chamber. R was determined using the Monte Carlo N-Particle version 5 (MCNP-5) code. Photons with (i) discrete energies, and (ii) continuous-energy distributions under different beam conditioning were considered. The four studied monoenergetic photons had energies E = 0.01, 0.1, 1 and 2 MeV...

Various types of radiation are utilized in the treatment of cancer. Equal physical doses of different radiation types do not always result in the same amount of biological damage. In order to account for these differences, a scaling factor known as the relative biological effectiveness (RBE) can be used. 137Cesium (137Cs) has been used as a source of radiation in a significant body of radiation therapy research. However, high-energy X-rays, such as 6 MV X-rays, are currently used clinically to treat patients...

Two equivalents of 1-benzyl-3-bromoethylbenzimidazolium bromide couple with Na2Se to produce the first selenoether bridged bis-benzimidazolium salt (LH2)Br2. The nitrate (LH2)(NO3)2 and tetrafluoroborate (LH2)(BF4)2 salts were also synthesized from (LH2)Br2. The reaction of Hg(OAc)2 with (LH2)Br2 gave the first pseudo pincer carbene mercury complex, [Hg(L-κ(2)C)][HgBr4] (C1). Different complexes of Pd(ii) with selenoether bridged carbene were obtained using (LH2)Br2 and (LH2)(NO3)2. Syntheses of these complexes were dependent on the counter anion and the temperature...

A strategy for the synthesis of 2-halo allylic aminal derivatives through regioselective 1,2-addition of allenamides with N-haloimides is presented. This reaction was conducted under very mild conditions and gave up to 99% yield. Moreover, the obtained halides allow functional group diversification by palladium-catalyzed coupling reactions, which could act as potential intermediates for the synthesis of valuable compounds.

Two stable cerium(iv) 3,5-dialkylpyrazolate complexes are presented, namely dimeric [Ce(Me2pz)4]2 (Me2pz = 3,5-dimethylpyrazolate) and monomeric Ce(tBu2pz)4 (tBu2pz = 3,5-di-tert-butylpyrazolate) along with their trivalent counterparts [Ce(Me2pz)3] and [Ce(tBu2pz)3]2. All complexes were obtained from protonolysis reactions employing the silylamide precursors Ce[N(SiHMe2)2]4 and Ce[N(SiMe3)2]3. Treatment of homoleptic Ce(IV) and Ce(III) Me2pz complexes with 1,4-hydroquinone (H2hq) or 1,4-benzoquinone (bq), respectively, ultimately gave the same trimetallic Ce(III) species via a cerium redox equilibrium...

The MOFs Cr carboxylate MIL-101(Cr) and Zn imidazolate ZIF-11 have different chemical and textural properties. These properties have been combined to prepare thin film nanocomposite (TFN) membranes for organic solvent nanofiltration (OSN) with the two MOFs simultaneously embedded in the same membrane. The TFN membrane containing only ZIF-11 permeated faster than that with only MIL-101(Cr) when filtering sunset yellow (SY) (4.9 L m(-2) h(-1) bar(-1)) and acridine orange (AO) (3.2 L m(-2) h(-1) bar(-1)), although MIL-101(Cr) alone gave rise in both cases to better rejections (above 90%)...

BACKGROUND: Laboratory assays that identify recent HIV infections are important for assessing impacts of interventions aimed at reducing HIV incidence. Kinetics of HIV humoral responses can vary with inherent assay properties, and between HIV subtypes, populations and physiological states. They are important in determining mean duration of recent infection (MDRI) for antibody-based assays for detecting recent HIV infections. METHODS: We determined MDRIs for BED-CEIA, LAg and BRAI assays for 101 seroconverting postpartum women, recruited in Harare in 1997- 2000 during the Zimbabwe Vitamin A for Mothers and Babies (ZVITAMBO) Trial, comparing them against published MDRIs estimated from seroconverting cases in the general population...

Simian virus 40 (SV40) large T antigen (LT) coding sequences were revealed in different human samples, whereas SV40 antibodies (Ab) were detected in human sera of cancer patients and healthy individuals, although with a lower prevalence. Previous studies carried out by the neutralization assay gave a SV40 seroprevalence, in the general population, up to 8%, although higher rates, 12%, were detected in kidney transplant children, in a group of HIV-positive patients, and in healthy females. In this study, serum samples from pregnant women, together with those from non-pregnant women, were analyzed to check the prevalence of IgG Ab reacting to SV40 LT antigens...

Mucin binding protein (Mub) of Lactobacillus plantarum- group (LPG) is considered as a potential marker gene due to its diversity and adherence property to host intestinal layer. We recently observed strain specific diversity in mub gene of LPG strains (n=8) and grouped them into Type I, II and III based on the insertion and/or deletion of MucBP domain repeats (Devi et al., 2016). The mub gene expression pattern noted by real-time PCR revealed 67.64 increased fold change in MTCC 9483 with four MucBP repeats...

Understanding the yield and failure mechanisms of ligaments and tendons is important to have a deeper knowledge of their structure and function. Evaluating what are the limits of the human body is also important to prevent injuries in workers, in athletes and the elderly. The tissue yield mechanism was analyzed by modifying and extending a probabilistic model of collagen bundles. Since not usable experimental data are available in the literature, the model and the method were tested using Monte Carlo simulations...

In the present work, the genotoxic effect of cadmium and lead supplied in a laboratory trial, was investigated for the first time in the moss Sphagnum palustre, by ISSR molecular markers. A total of 169 reproducible bands were obtained with 12 primers, ten of which gave polymorphisms (i.e., appearance/disappearance of bands), indicating a clear genotoxic effect induced by the metals. Both metals induced a decrease of the genome template stability in a dose dependent manner. At concentration >10(-5) Cd also induced a general toxic effect in S...
