AIM The aim of this study was to investigate in vitro the utility of biologically compatible, nontoxic and cell-specific targetable hydrogel nanoparticles (NPs), which have Coomassie® Brilliant Blue G dye (Sigma-Aldrich, MO, USA) covalently linked into their polyacrylamide matrix, as candidates for photothermal therapy (PTT) of cancer cells. MATERIALS & METHODS Hydrogel NPs with Coomassie Bri...

In this Phase I SBIR research, we proved the feasibility of a semi-automated part-task trainer (PTT) prototype development environment. In this effort, we set out to address the shortfalls of traditional PTTs and to introduce new concepts into the PTT prototyping process. The research developed innovative rapid prototyping techniques for the development of PTT prototypes. These techniques are l...

We introduce the polynomial-time tree reducibility (ptt-reducibility). Our main result states that for languages B and C it holds that B ptt-reduces to C if and only if the unbalanced leaf-language class of B is robustly contained in the unbalanced leaf-language class of C. This is the unbalanced analogue of the well-known result by Bovet, Crescenzi, Silvestri, and Vereshchagin which connects p...

BACKGROUND AND OBJECTIVE Treatment modalities, such as hyperthermia and photodynamic therapy (PDT) have been used in the treatment of a variety of head and neck squamous cell carcinoma (HNSCC), either alone or as an adjuvant therapy. Macrophages loaded with gold nanoshells, which convert near-infrared light to heat, can be used as transport vectors for photothermal hyperthermia of tumors. The p...

Background: Sleep is essential for everyone and is important for normal human functioning. Lack of sleep, called sleep deprivation, is a condition leading to poor sport training and achievements. Different factors contribute to sleep deprivation in athletes. Respiratory sleep disorders as Upper Airway Resistance Syndrome (UARS) and Obstructive Sleep Apnea (OSA) are factors that rebound most to ...

Many tumor-targeted strategies have been used worldwide to limit the side effects and improve the effectiveness of therapies, such as chemotherapy, radiotherapy (RT), etc. Biophotonic therapy modalities comprise very promising alternative techniques for cancer treatment with minimal invasiveness and side-effects. These modalities use light e.g., laser irradiation in an extracorporeal or intrave...

In recent years, penile traction therapy (PTT) has gained considerable interest as a novel nonsurgical treatment option for men with Peyronie's disease (PD) and short penises. The current published literature suggests that selected cases of PD may benefit from a conservative approach with PTT, resulting in increased penile length and reduction of penile deformity. It appears to be safe and well...

Abstract This study used shell noun as the starting point to analyze language activities that word shì shí shàng ‘in fact’ by Internet users on PTT , understand truth event this empty signifies; and identify characteristics of pragmatic practice in texts screened noun. Through Tool, posts with more than 100 comments Gossip board during level 3 alert were first out, after which “in fact” identif...

Abstract Phototherapy usually includes photodynamic therapy (PDT) and photothermal (PTT) to induce cell death. PDT utilizes the sensitization of photosensitizers generate reactive oxygen species by intersystem crossing while PTT undergoes nonradiative decay heat. Cancer immunotherapy has evolved as a new therapeutic modality eradicate tumor cells activating antigen-presenting cells, thus, induc...

INTRODUCTION The Paediatric Triage Tape (PTT) is an easy to use major incident primary triage tool, based upon a modification of the Triage Sieve. The purpose of this study was to prospectively validate the PTT for use in paediatric major incidents. METHODS A database of children presenting the Trauma Unit of the Red Cross Children's Hospital, Cape Town, was developed over a nine month period...
