We examined the structural components of pertussis toxin that are required for efficient export from Bordetella pertussis via the Ptl system, a member of the type IV family of macromolecular transporters. First, we constructed a strain of B. pertussis that contains a functional Ptl system but does not produce pertussis toxin. Plasmids which express either the S1 subunit or the B oligomer were t...
Introduction Intramuscular and vaginal progesterone are recommended for prevention of preterm labor (PTL) in women with risk factors. Studies are emerging to indicate that HIV-infected women on combination antiretroviral therapy (cART) are at risk of PTL and low birth weight (LBW), and may benefit from supplemental progesterone. This study aims to determine the perceived acceptability of variou...
BACKGROUND Primary thyroid lymphoma (PTL) is uncommon, accounting for 2% to 5% of all thyroid malignancies. Papillary thyroid carcinoma (PTC) is the most frequent thyroid cancer. The coexistence of PTL and PTC is very rare, and the preoperative diagnosis is rather difficult. METHODS A 41-year-old male patient complaining of fast painless thyroid enlargement for 2 months and a cervical mass fo...
PROBLEM To study the relationship between perinatal prognosis in cases of preterm labor (PTL) and polymicrobial infection in amniotic fluid (AF) and intra-amniotic (IA) inflammation using a highly sensitive and reliable PCR-based method. METHOD OF STUDY To detect prokaryotes using a nested PCR-based method, eukaryote-made thermostable DNA polymerase without bacterial DNA contamination was use...
Sesquiterpene lactones (SL) have a wide range of applications in anti-tumor and anti-inflammatory therapy. However, the pharmacological mechanism of such substances is not clear. In this study, parthenolide (PTL) was used as an example to explore the anti-tumor effect of natural molecules and their common mechanism. We showed that PTL inhibited the proliferation and migration by reverse EMT via...
In several design methods for Pass-transistor Logic (PTL) circuits, Boolean functions are expressed as OBDDs in decomposed form and then the component OBDDs are directly mapped to PTL cells. The total size of OBDDs (number of nodes) corresponds to the circuit size. In this paper, we investigate a method for PTL synthesis based on exact minimization of Free BDDs (FBDDs). FBDDs are well-studied e...
Primary thyroid lymphomas (PTL) are very rare and account for only 2.5% to 5% of all thyroid malignancies and 1-2% of all extra-nodal malignancies [1]. PTL is more prevalent in females in the sixth to seventh decade of life [2]. The presentation of PTL can be puzzling. PLT may be mistaken for anaplastic thyroid cancer. Immunochemistry is an important part of pathologic differentiation of these ...
Temporal logic has been extensively utilized in academia and industry to formally specify and verify behavioural properties of numerous kinds of hardware and software. We present a novel way to apply temporal logic to the study of a version of itself, namely, propositional linear-time temporal logic (PTL). This involves a hierarchical framework for obtaining standard results for PTL, including ...
In this study, a commercial IrO 2 /TiO catalyst (75 wt% Ir, named “Benchmark”) for the oxygen evolution reaction (OER) is compared to newly developed IrO(OH) x (45 “P2X”). Due its lower Ir packing density and higher OER activity vs Benchmark (440 12 A g −1 at 1.43 V iR-free ), P2X shows an improved PEM (proton exchange membrane) water electrolyzer performance ≈9 times reduced loading, however, ...
