Mechanical Characterization of Flax and Hemp Fibers Cultivated in Romania.

This study examines the mechanical properties, specifically strength and stiffness, of technical hemp and flax fibers grown in Romania. Tensile testing was employed to determine stress-strain curves and the Young's modulus and to assess the failure strength of both fiber types. Although samples of various lengths were tested, no significant length-dependent variations were observed.

Construction and validation of conceptual and operational definitions of the defining characteristics of the nursing diagnosis "Ineffective health self-management" in people living with HIV/AIDS.

Purpose: Build and validate the content of conceptual and operational definitions of the defining characteristics of the nursing diagnosis of NANDA-I "Ineffective health self-management" in people living with HIV/AIDS.

Methods: Methodological study, with a quantitative approach. The validation was performed by 26 specialist nurses selected through the Lattes do Brazil platform.

Clinical and histopathological aspects in two cases of ligneous conjunctivitis.

Ligneous conjunctivitis represents a very rare form of chronic membranous conjunctivitis, with unknown etiology; less than 200 cases have been reported in the literature, most of them in infants and children. After 40 years, this condition appears in exceptional circumstances. We present, in this study, two patients (of 55 and 64 years old) with very severe forms of ligneous conjunctivitis, certified by histopathological examination, one of them being previously diagnosed with Lyell's syndrome.

Impression conjunctival cytology in sicca syndrome - correlations between clinical and histological findings related to dry eye severity.

Keratoconjunctivitis sicca represents a progressive deterioration of ocular surface produced by a deficient secretion of lachrymal film (quantitative disorder) or excessive tear evaporation (qualitative disorder). The cytological analysis of conjunctival impression in 42 patients with dry eye syndrome established a strong correlation between the clinical grade of severity of disease and the grade of squamous metaplasia, including goblet cell loss. The cellular anomalies were represented by modifications of keratinization, epithelial cells' anisocytosis, anisochromia, the nuclear condensation and the cytoplasmic vacuolization.

RETINAL ANGIOMATOUS PROLIFERATION CASE REPORT.

The diagnosis of RAP is similar with the diagnosis of the AMD, but PED, exudate and superficial hemorrhages are more common in RAP. A 75-year-old male presented himself at the Ophthalmology Department of the Emergency County Hospital in Craiova in January 2015, with a 4 months history of vision loss. In his right eye the visual acuity was 4/50 eye non-optical correctable and 5/5 with optical correction in the left eye.
