abstract background: for infertile women aged over 35 years, failure of the zp (zona pellucida) to rupture is believed to be associated with a decreased implantation rate in in vitro fertilization (ivf) or intra cytoplasmic sperm injection (icsi). objective: in this research, laser assisted hatching (lah) was offered to patients with advanced maternal age to evaluate a possible benefit. materia...

Two different extraction methods were used for a comparative study of algerian myrtle leaf essential oils: solvent-free-microwave-extraction (SFME) and conventional hydrodistillation (HD). Essential oils analyzed by GC and GC-MS presented 51 components constituting 97.71 and 97.39% of the total oils, respectively. Solvent-Free-Microwave-Extract Essential oils SFME-EO were richer in oxygenated c...

The present study aimed to investigate the physicochemical and energy characteristics of Pinus nigra Arn. (Pinaceae family) coniferous biomass used after production essential oil. biomass, comprised needles with twigs, was milled subjected sieve analysis, thus producing three groups particle fractions (between 384 413 μm). infrared spectrum recorded as 4000–400 сm–1. results from revealed signi...

The aim of this work is to determine the effect extraction method on yield, chemical composition, and antifungal activity cedarwood essential oils (EOs) from sawdust Moroccan Cedrus atlantica (C. atlantica). EOs were extracted by different methods: hydrodistillation, soxhlet, maceration, ultrasound. composition was determined using gas chromatography mass spectrometry (GC-MS) analysis. yields 5...
