Expression of RPL9 predicts the recurrence of non-muscle invasive bladder cancer with BCG therapy.

Numerous biomarkers and risk tables can be used to predict recurrence or progression of patients with primary or recurrent non-muscle invasive bladder cancer (NMIBC) receiving Bacillus Calmette-Guerin (BCG). However, few are suitable for BCG-unresponsive disease (i.e.

Urinary hsv2-miR-H9 to hsa-miR-3659 ratio is an effective marker for discriminating prostate cancer from benign prostate hyperplasia in patients within the prostate-specific antigen grey zone.

Purpose: Tumor microRNAs (miRNAs) are released to biofluids directly or indirectly. Although urinary miRNAs are promising non-invasive biomarkers for the diagnosis of prostate cancer (PCa), their clinical application is challenging for technical reasons. We examined the efficacy of urinary hsv2-miR-H9 to hsa-miR-3659 ratio as a non-invasive diagnostic biomarker of PCa.

Precisely tuned photonic properties of crystalline nanocellulose biocomposite coatings by gradually tailored nanoarchitectures.

Inspired by nature, we fabricated optically tuned bio-organic films of cellulose nanofibers (CNFs) and chitosan by precisely structuring layer-by-layer (LBL) assembly techniques. Directly extracted from tunicate, highly crystalline CNFs were deposited into gradual nanoporous structures, which dictates wave-like behaviors of optical transmittance and cyclic patterns of structural coloration. The optical transmittance of a glass substrate increased from 91% to 98.

High crystallinity of tunicate cellulose nanofibers for high-performance engineering films.

Tunicate cellulose nanofibers (CNFs) have received widespread attention as renewable and eco-friendly engineering materials because of their high crystallinity and mechanical stiffness. Here, we report the effects of disintegration process conditions on structure-property relationships of tunicate CNFs. By varying the hydrolysis time, we could establish a correlation between crystallinity of the CNFs with linearity and stiffness, which produces different molecular ordering within their nanostructured films.

Anthricin (deoxypodophyllotoxin) is a major lignan in Anthriscus sylvestris and possesses many bioactivities such as antiproliferative, antitumor, anti‑platelet aggregation, antiviral and anti‑inflammatory actions. However, the anticancer effects of anthricin on A549 human non‑small cell lung cancer cells and potential molecular mechanisms remain unknown. Therefore, we investigated the anticancer effect of anthricin and the underlying mechanism in A549 cells.

Adenosine induces intrinsic apoptosis via the PI3K/Akt/mTOR signaling pathway in human pharyngeal squamous carcinoma FaDu cells.

Adenosine has been identified to occur abundantly intra-and extracellularly, and to exert diverse biological functions, including the suppression of cell proliferation and the induction of apoptosis. Adenosine has been reported to induce apoptosis in several cancer cell lines; however, to the best of our knowledge, the effect of adenosine on head and neck cancer cells has not been investigated. Therefore, the purpose of the present study was to evaluate whether adenosine exerts any anticancer effect via induction of apoptosis in human pharyngeal squamous carcinoma FaDu cells.

Invasive Micropapillary Carcinoma in Axillary Ectopic Breast and Synchronous Ductal Carcinoma in the Contralateral Breast.

The development of ectopic breast tissue is attributable to the failure of primitive mammary tissue to regress after the development of the mammary ridge, except at pectoral breast sites, and is most often evident in the axillae. Several benign and malignant breast diseases have been reported in ectopic axillary breast tissues. The most common cancerous pathology of ectopic breast tissue is invasive ductal carcinoma.
