Electrospun Nanosystems Based on PHBV and ZnO for Ecological Food Packaging.

The electrospun nanosystems containing poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and 1 wt% Fe doped ZnO nanoparticles (NPs) (with the content of dopant in the range of 0-1 wt% Fe) deposited onto polylactic acid (PLA) film were prepared for food packaging application. They were investigated by scanning electron microscopy (SEM), energy dispersive X-ray (EDX), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), antimicrobial analysis, and X-ray photoelectron spectrometry (XPS) techniques. Migration studies conducted in acetic acid 3% (/) and ethanol 10% (/) food simulants as well as by the use of treated ashes with 3% HNO solution reveal that the migration of Zn and Fe falls into the specific limits imposed by the legislation in force.

Magnetic resonance imaging characteristics of chronic prostatitis in patients under the age of 50: is it more than the eye can see?

Background: The magnetic resonance (MRI) diagnosis of chronic prostatitis (CP) is insufficiently evaluated.

Purpose: To evaluate the MRI appearance of CP in young patients by comparing it to individuals with non-prostatic related pathology.

Material And Methods: The study included 47 patients with prostatitis-like symptoms evaluated by urologists and referred to pelvic MRI examination (mean age=40.

Study of physico-chemical characteristics of wastewater in an urban agglomeration in Romania.

This study investigates the level of wastewater pollution by analyzing its chemical characteristics at five wastewater collectors. Samples are collected before they discharge into the Danube during a monitoring campaign of two weeks. Organic and inorganic compounds, heavy metals, and biogenic compounds have been analyzed using potentiometric and spectrophotometric methods.

[Abdominal wall endometriosis after gynecologic procedures: an under-appreciated diagnosis in general surgery].

Unlabelled: Incisional endometriosis is a clinical entity described in the gynecologic literature but it is not well recognized among general surgeons. The preoperative diagnosis is often mistaken for a suture granuloma, abscess, lipoma, cyst or incisional hernia.

Material And Method: This is a retrospective review of six cases of incisional endometriosis in our hospital aimed at determining which, if any, factors would suggest the diagnosis preoperatively.

[Long-term results after surgery for colorectal adenocarcinoma, stage I-III. Problems of prognosis].

Unlabelled: Colorectal cancer is one of the leading causes of cancer-related death worldwide.

Study Design: Prospective study on 142 consecutively cases with stage I to III colorectal adenocarcinomas (TNM AJCC/UICC) in which patients underwent potentially curative surgery in one single public health service (1st Surgical Clinic Iaşi, Romania) between 2004 and 2005.

Material And Method: The mean follow-up was 23.

[Hydatic cyst of the liver. Considerations on 337 cases].

Hydatid disease of the liver is still endemic in certain parts of the world. The modern treatment of hydatid cyst of the liver varies from surgical intervention to percutaneous drainage or medical therapy. Surgery is still the treatment of choice and can be performed by the conventional or laparoscopic approach.
