Novel Gold Nanorods@Thiolated Pectin on the Killing of HeLa Cells by Photothermal Ablation.

Gold nanorods (AuNRs) have attracted attention in the field of biomedicine, particularly for their potential as photothermal agents capable of killing tumor cells by photothermic ablation. In this study, the synthesis of novel AuNRs stabilized with thiolated pectin (AuNR@SH-PEC) is reported. To achieve this, thiolated pectin (SH-PEC) was obtained by chemically binding cysteamine motifs to the pectin backbone.

Human intestinal protozoa in fresh asparagus from different types of markets in northwest Mexico.

Caborca is one of the most productive asparagus-growing regions in the state of Sonora in northwest Mexico, an area where some fresh fruits and vegetables are sold at unregulated open-air street markets. This is a cross-sectional study in which fifty bundles of asparagus for exportation, 50 bundles of sub-standard asparagus, and 50 bundles of asparagus from open-air markets were selected randomly and then subjected to Faust, Kinyoun and ELISA testing to detect intestinal parasites. Pearson's chi-square (χ2) and Student-NewmanKeuls tests were used to estimate differences among the sampling site groups (P < 0.

Evaluation of Antioxidant Capacity, Protective Effect on Human Erythrocytes and Phenolic Compound Identification in Two Varieties of Plum Fruit (Spondias spp.) by UPLC-MS.

Plum edible part was used to obtained extracts by during a 4 h maceration process using three different solvents (ethanol, methanol and water) for the determination of total phenols and flavonoids, antioxidant capacity by (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS), 2,2-diphenyl-1-picrylhydrazyl (DPPH) and hemolysis inhibition in human blood assays. Subsequently, phenolic compounds were identified using ultra-performance liquid chromatography (UPLC-MS). The results indicated that the ethanolic extract of plum fruit being a good source of phenolic (12⁻18 mg GAE/g FW) and flavonoids (2.

Prognostic factors in neoadjuvant treatment followed by surgery in stage IIIA-N2 non-small cell lung cancer: a multi-institutional study by the Oncologic Group for the Study of Lung Cancer (Spanish Radiation Oncology Society).

Purpose: To evaluate the prognostic factors associated with survival in patients treated with neoadjuvant treatment [chemoradiotherapy (CRT) or chemotherapy] followed by surgery (CRTS) in patients with stage IIIA-N2 non-small cell lung cancer (NSCLC).

Methods: A retrospective study was conducted of 118 patients diagnosed with stage T1-T3N2M0 NSCLC and treated with CRTS at 14 hospitals in Spain between January 2005 and December 2014. Overall survival (OS) and progression-free survival (PFS) were estimated using the Kaplan-Meier method and compared using the log-rank test.

Microencapsulation of Carvacrol Using Pectin/Aloe-gel as a Novel Wound Dressing Films.

Recently, Pectin (PEC) and Aloe-Gel (AG) have received great attention for their use in the encapsulation of hydrophobic bioactive compounds such as Carvacrol (CAR). The aim of this study is to assess the physical, chemical and biological properties of a novel PEC/AG film and evaluate its capability to entrap CAR into microencapsulates. For this purpose, the casting method was used to prepare the PEC/AG membranes (70:30 % w/w).

Neoadjuvant treatment followed by surgery versus definitive chemoradiation in stage IIIA-N2 non-small-cell lung cancer: A multi-institutional study by the oncologic group for the study of lung cancer (Spanish Radiation Oncology Society).

Objectives: The role of surgery in stage IIIA-N2 non-small cell lung cancer (NSCLC) is an actively debated in oncology. To evaluate the value of surgery in this patient population, we conducted a multi-institutional retrospective study comparing neoadjuvant chemoradiotherapy or chemotherapy plus surgery (CRTS) to definitive chemoradiotherapy (dCRT).

Material And Methods: A total of 247 patients with potentially resectable stage T1-T3N2M0 NSCLC treated with either CRTS or dCRT between January 2005 and December 2014 at 15 hospitals in Spain were identified.
