Introduction: The multipurpose nanocomposites have gained growing biomedical attention as promising nanotheranostics to improve The effectiveness of cancer treatment, which concurrently combine advantages of the therapeutic and diagnostic techniques into one nanosystem. The “all-in on” probes not only help to ablate cancerous tumors, but also allow to optimize and monitoring of...
Phosphorus Concentrations in Sequentially Fractionated Soil Samples as Affected by Digestion Methods
Sequential fractionation has helped improving our understanding of the lability and bioavailability of P in soil. Nevertheless, there have been no reports on how manipulation of the different fractions prior to analyses affects the total P (TP) concentrations measured. This study investigated the effects of sample digestion, filtration, and acidification on the TP concentrations determined by I...
Investigations were carried out to isolate microbial strains from soil, mud and water samples from metallurgically polluted environment for bioremediation of toxic heavy metals. As a result of primary and secondary screening various 72 acidothermophilic autotrophic microbes were isolated and adapted for metal tolerance and biosorption potentiality. The multi-metal tolerance was developed with h...
We attempted a simple pretreating method consisting of solid-phase extraction using bonded silica gel with benzenesulfonic acid (SCX) as the solid-phase sorbent to determine trace elements in pure molybdenum samples by means of inductively coupled plasma mass spectrometry (ICP-MS). Molybdenum was anionized by adding hydrogen peroxide solution to a sample decomposed with acid, and separated from...
UNLABELLED A challenge in obstetrics is to distinguish pathological symptoms from those associated with normal changes of pregnancy, typified by the need to differentiate whether gestational pruritus of the skin is an early symptom of intrahepatic cholestasis of pregnancy (ICP) or due to benign pruritus gravidarum. ICP is characterized by raised serum bile acids and complicated by spontaneous p...
introduction: this study was carried out to determine elements (li, na, k, mg, ca, ba, b, al, si, v, cr, mn, fe, co, ni, cu, zn, se, ag and p) in the suaeda vermiculata (s. vermiculata) and suaeda aegyptiaca (s. aegyptiaca) in three different regions of southern iran using inductively coupled plasma optical emission spectrometry (icp-oes) after microwave-assisted acid digestion. materials and m...
due to environmental problems caused by mining activities, it is necessary to study and investigation the concentrations of the pollutants caused by this activities such as heavy metals. the aim of this study is the determination of the concentration of heavy metals cu, pb and zn in roots of two species of artemisia including artemisia aucheri and artemisia sieberi in the surrounding natural la...
In this study, daily fine particulate matters (PM2.5) were sampled between 22 February 2011 and 2012 in Bolu Abant ?zzet Baysal University Campus. 277 PM2.5 samples collected by using a stacked filter unit. Fifty-one elements (Li, Be, Na, K, Mg, Al, P, S, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ge, As, Se, Rb, Sr, Y, Mo, Cd, Sn, Sb, Cs, La, Ce, Pr, Nd, Eu, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Hf,...
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
Determination of trace elements in cells is critical to metallomics research and still faces tremendous difficulties even with the help of highly sensitive inductively coupled plasma mass spectrometry (ICP-MS). Microfluidic chips offer a functional tool-set for cell analysis with features of miniaturization, integration and automation. In this work, we proposed a chip-based array magnetic solid...
