Lin@Tetracyanoethylene (n = 1–4) systems: Lithium salt vs lithium electride

Electrides are interesting and promising materials with cavity-trapped electrons which can be used as source of electron donor in different systems. Hereby, we have explored the possible formation of electride materials based on tetracyanoethylene (TCNE) backbone at MP2 computational level. This is achieved by systematic addition of up to four Li atoms to TCNE backbone. Our results predict high thermodynamic stability in the Li@TCNE (n = 1–4) systems. Moreover, based on the evaluation of four criteria, non-nuclear attractor (NNA), electron localization function (ELF), electron density laplacian (∇ρ(r)), and non-linear optical (NLO), TCNE-Li and TCNE-Li and TCNE-Li species are conventional donor-acceptor systems (lithium salt). In contrast, the TCNE-Li species can be introduced as lithium electride with cavity-trapped electrons. Therefore, Li:TCNE ratio is very significant factor to provide species with electride feature through the addition of Li atoms to TCNE backbone.Peer Reviewe

Successful topical treatment of a gunshot wound: A case report

Gunshot wound leads to deep soft tissue damages known as penetrating trauma. Wound healing in patient with the gunshot is a dynamic and complex process that requires a suitable approach to promote the healing process. The reason for this is that such wounds are usually deep and extensive. Modern wound dressing in perforated wounds without a fracture or neurovascular injury may be considered for wound healing of outpatients. We report on an 18-year-old girl patient with gunshot wound who was referred to the wound clinic. The symptoms of wound dehiscence in the periumbilical site were observed following to lose suture after primary surgery. Therefore, a new special dressing approach was adopted. Healing of periumbilical wound was successfully achieved at the end

A study on aroma release and perception of saffron ice cream using in-vitro and in-vivo approaches

The effect of fat nature (dairy fat, and combination of dairy fat with sunflower oil) and its substitution with whey protein isolate (WPI) (0, 5% and 7.5%) on aroma release and perception from six saffron ice creams was studied through in-vitro, retro- and ortho-nasal approaches, and sensory evaluation. Compared with full-fat (10% fat) saffron ice creams, light (5% fat) and low-fat (2.5% fat) samples were accompanied with more safranal release into the vial headspace (0.0126, 0.0177, and 0.0220 ppm, respectively) and mouth cavity (100%, 153.6%, and 235.6%, respectively). Gas chromatography/Olfactometry showed that the most sensation of the majority of aroma compounds was from - low-fat and dairy fat-based samples. Results of in-mouth and ortho-nasal pathways studies coincided, indicating no significant difference (P<0.05) in aroma release among full-fat and light samples with two different fat types. These findings would suggest WPI as an appropriate fat replacer in light saffron ice creams for aroma delivery purposes

Tear Film, Lacrimal Drainage System, and Eyelid Findings in Subjects with Anophthalmic Socket Discharge

Purpose To compare the results of tear film and lacrimal drainage system tests between anophthalmic socket and normal eye and assess discharge characteristics and frequency of prosthesis removal (questionnaire), eyelid function, and meibomian glad dysfunction (MGD). Design Prospective masked case control. Methods Subjects (�6 years and �6 months of wearing prosthesis) with unilateral acquired anophthalmic socket discharge were included. Excluded was ocular adnexal abnormality of any reason and incomplete tests. The subjective questionnaire was completed. Blinking rate, lagophthalmos, eyelid laxity, MGD, Schirmer test, tear meniscus height, and dye disappearance test were assessed by a masked examiner. Another masked examiner performed an irrigation test 1 week later and interpreted the scintigraphy images at the end of the study. Results Included were 50 subjects (mean age: 31.3 years, mean prosthesis wear: 96.1 months). Discharge was frequent or very frequent in 85, mucoid or mucopurulent in 90, and moderate to severe in 86 of the subjects. MGD in 58, lagophthalmos in 80, and eyelid laxity in 46 were observed. Anophthalmic socket sides showed a significantly lower tear production and higher tear drainage obstruction. Subjects with frequent prosthesis removal had a significantly (P =.02) greater lagophthalmos and blinking rate (P =.04). The blinking rate was also significantly greater in subjects with higher frequency of discharge (P =.04). Conclusion Tear film impairment (aqueous and lipid) and lacrimal drainage obstruction should be considered in subjects with anophthalmic socket discharge. A significantly higher blinking rate and lagophthalmos were found in subjects with higher frequency of prosthesis removal. © 2016 Elsevier Inc. All rights reserved
