AIMS To investigate whether lupus anticoagulant (LA) positivity, a marker of endothelial dysfunction, might be relevant to the pathogenesis of diabetic retinopathy (DR). METHODS 32 IDDM patients were examined for LA, fibrinogen, prothrombin (PT), PTT, prothrombin degradation products (F1+2), and activated protein C (APC). RESULTS APC decreased and F1+2 increased significantly in LA positive...

This paper develops robust test procedures for testing the intercept of a simple regression model when it is apriori suspected that the slope has a specified value. Defining unrestricted test (UT), restricted test (RT) and pre-test test (PTT) corresponding to the unrestricted (UE), restricted (RE), and preliminary test estimators (PTE) in the estimation case, the M-estimation methodology is use...

Phase behavior and its effects on crystallization in an extruded poly(trimethylene terephthalate) (PTT)/phenoxy resin blend were studied with time-resolved light scattering (TRLS), optical microscopy (OM), differential scanning calorimetry (DSC), and small-angle X-ray scattering (SAXS). During annealing in the molten state, a two-phase structure with unique periodicity and phase connectivity wa...

Abstract As a key branch of the cross-discipline biophotonics, phototherapy, including photodynamic therapy (PDT), and photothermal (PTT), is promising in biomedicine visible light-driving PDT has been applied to clinical treatment. However, extensive applications phototherapy are limited by hypoxic microenvironment, laser penetration depth, potential complexity for combined PDT/PTT. Thus, NIR-...

T hromboembolic (TE) prophylaxis using lowdose unfractionated heparin (LD-UFH), ie, 5000 IU given subcutaneously twice or 3 times daily is effective, has low bleeding risk, and is generally not expected to prolong partial thromboplastin times (PTTs). Laboratory monitoring or dose adjustments based on weight or renal function are not considered necessary. An index case at our institution prompte...

Due to the high incidence and mortality rates of cancer, it is necessary seek more targeted effective treatment methods. Traditional cancer methods have problems such as incomplete significant side effects. In recent years, photothermal therapy (PTT) has been considered one most promising in biomedical field. The principle PTT use materials with conversion efficiency absorb near-infrared light ...

Dual Forms of Reed–Muller (DFRM) are implemented in OR/XNOR forms, which are based on the features of coincidence operation. Map folding and transformation techniques are proposed for the conversion between Boolean and DFRM expansions. However, map techniques can only be used for up to 6 variables. To overcome the limitation, serial tabular technique (STT) and parallel tabular technique (PTT) a...

Discrete choice experiments (DCEs) are robust stated-preference methods frequently used to estimate maximum acceptable risk (MAR) as a secondary outcome. However, DCEs provide sample-level estimates and explaining preference heterogeneity for MARs based on participant characteristics can be difficult. The study objective was compare the capability of DCE probabilistic threshold technique (PTT) ...

Time reliability in a Rail Transit Network (RTN) is usually measured according to clock-based trip time, while the travel conditions such as comfort and convenience cannot be reflected by time. Here, crowding level of trains, seat availability, transfer times are considered compute passengers’ Perceived Trip (PTT). Compared with average PTT, extra PTT needed for arriving reliably, which equals ...
