Phenylethynyl-bridged dipyrrin "dimers" have performed ZnII complexation to give coordination polymers, which provided the fluorescent colloidal spherical objects in solution as well on substrate according spacer units. Using a mixture of THF and water, unique morphologies, such bell-shaped "golf ball"-like architectures, were observed.

Trabectedin extravasation can cause significant soft tissue disorders. Early surgical intervention has been recommended in the event of chemotherapeutic extravasation; however, treatment tends to remain conservative. is a vesicant drug that associated with risk delayed damage; therefore, leaks should be promptly stopped. Complications central venous (CV) ports include infection, catheter damage and obstruction, which lead trabectedin extravasation. In present case report, 61-year-old woman...

Head and neck squamous cell carcinoma (HNSCC) patients with human papillomavirus (HPV) infection have better prognosis than those without HPV infection. Although p16(INK4a) expression is used as a surrogate marker for infection, there controversy to whether reliably indicates Here, evaluate the accuracy of determining prognostic value HNSCC survival, especially oropharyngeal (OPSCC) 150 fresh-frozen samples were analyzed DNA, E6/E7 mRNA by polymerase chain reaction immunohistochemistry. was...

Abstract Background The purpose of this study was to determine prospectively both human papillomavirus (HPV) load and physical status in different types head neck squamous cell carcinoma (HNSCC). Methods HPV DNA, E6/E7 mRNA expression, viral load, 184 patients with HNSCC were examined simultaneously by polymerase chain reaction (PCR)‐based methods. Results genome detected 54 samples (29.3%), particularly tonsillar carcinomas (69.6%). Compared nonoropharyngeal HNSCC, oropharyngeal harbored a...

A microscopic theory is presented to explain how the melting point in metallic small particles dependent on size. The systems are described by an effective pair interaction of Gaussian type, constructed give basic thermodynamic properties bulk metal at low temperatures. temperature, which difference between total Helmholtz free energy a solid particle and that liquid same mass vanishes, used as criterion actual particles. variational principle based Gibbs-Bogoliubov inequality calculate...

To investigate the prevalence, genotypes, and prognostic values of Epstein-Barr virus (EBV) human papillomavirus (HPV) infections in Japanese patients with different types head neck cancer (HNC).HPV EBV DNA, genotypes LMP-1 variants, HPV mRNA expression were detected by PCR from fresh-frozen HNC samples. determined direct sequencing, encoded RNA (EBER) was examined situ hybridization.Of 209 patients, 63 (30.1%) had infection, HPV-16 most common subtype (86.9%). E6/E7 found 23 60 (38.3%)...

This study aimed to determine the accuracy of acetabular cup insertion using a novel accelerometer-based navigation system in total hip arthroplasty (THA).A single-surgeon was conducted which 62 prospective patients with and 42 retrospective without supine position were compared. Absolute values for errors radiographic inclination anteversion calculated. Navigation error also Factors that affected absolute value alignment determined.In group, mean 4.1° 4.3°, respectively. In control 6.6° (p...

This study aimed to compare the cutting and component placement accuracies early outcomes after total knee arthroplasty (TKA) between an image-free handheld robotic system (NAVIO) a radiography-based (ROSA). retrospective included 88 patients (88 knees) who underwent TKA using NAVIO (40 patients) or ROSA (48 systems. The of systems were compared. Clinical scores evaluated Knee Society Score 2011 (KSS 2011) forgotten joint score (FJS)-12 at 1 year postoperatively. femoral sagittal error was...

Background: Complications associated with metal-on-metal (MOM) prostheses, such as adverse reactions to metal debris (ARMDs), include pseudotumor (PT) formation, metallosis, and soft tissue necrosis. High short-term failure rates have been reported for various MOM total hip arthroplasties (THAs) due ARMDs. ARMDs in THAs can potentially lead secondary modes, dislocation or infection. Objectives: This study aims examine the cumulative incidence of revisions periprosthetic joint infection (PJI)...
