Tumor blood flow (TBF) plays a fundamental role in tumor growth and treatment, and is characterized by spatial and temporal heterogeneities. Here we show that the interstitial fluid pressure (IFP), which is higher in tumoral tissue than in normal tissue, coupled with the tumor microvascular pressure (MVP) and the higher permeability of tumoral vessels, can explain the sustained oscillatory beha...

The initial reactions in the cometabolic oxidation of the gasoline oxygenate, methyl tert-butyl ether (MTBE), by Mycobacterium vaccae JOB5 have been characterized. Two products, tert-butyl formate (TBF) and tert-butyl alcohol (TBA), rapidly accumulated extracellularly when propane-grown cells were incubated with MTBE. Lower rates of TBF and TBA production from MTBE were also observed with cells...

BACKGROUND Flexible endoscopes undergo repeated rounds of patient-use and reprocessing. Some evidence indicates that there is an accumulation or build-up of organic material that occurs over time in endoscope channels. This "buildup biofilm" (BBF) develops as a result of cyclical exposure to wet and dry phases during usage and reprocessing. This study investigated whether the BBF matrix represe...

Temporary bonding film (TBF) is one of the key materials for assembly process fan out wafer level package (FOWLP). In this paper, we have proposed a novel TBF and xenon flash lamp de-bonding system. The was mainly composed cross-linkable low-polarity polymers to meet various requirement not only easy peeling-off after but also stability against thermal chemical environment exposed in FOWLP proc...

Tick bite fever (TBF) and Q fever are zoonotic infections, highly prevalent in southern Africa, which are caused by different genera of obligate intracellular bacteria. While TBF was first described nearly 100 years ago, it has only recently been discovered that there are several rickettsial species transmitted in southern Africa, the most common of which is Rickettsia africae. This helps to ex...

Measurements of tumor blood flow (TBF) are important for understanding tumor physiology and can be valuable in selecting and evaluating therapies. Brain tumors typically present reduced blood flows compared to normal brain tissue. This study shows that the arterial spin labeling (ASL) technique can be used to measure TBF non-invasively in a rat glioma model. Results show that TBF in the core (3...

Tick-borne flaviviruses (TBFs) affect human health globally. Human vaccines provide protection against some TBFs, and antivirals are available, yet TBF-specific control strategies are limited. Advances in genomics offer hope to understand the viral complement transmitted by ticks, and to develop disruptive, data-driven technologies for virus detection, treatment, and control. The genome assembl...

The thermo-fluidic transport characteristics of ferrofluids can be influenced by the application a magnetic field. manipulations have been useful in augmenting heat transfer, as evident from recent investigations. In present study, we examine novel strategy for two-phase transfer and show that manipulation non-boiling Taylor bubble flow (TBF) provide on-demand augmentation. an earlier investiga...

We tested a general method for the identification of drug resistance loci in the trypanosomatid protozoan parasite Leishmania major. Genomic libraries in a multicopy episomal cosmid vector were transfected into susceptible parasites, and drug selections of these transfectant libraries yielded parasites bearing cosmids mediating resistance. Tests with two antifolates led to the recovery of cosmi...

Humans need to be able to selectively control their memories. This capability is often investigated in directed forgetting (DF) paradigms. In item-method DF, individual items are presented and each is followed by either a forget- or remember-instruction. On a surprise test of all items, memory is then worse for to-be-forgotten items (TBF) compared to to-be-remembered items (TBR). This is though...
