Determination of the chemical main composition and anti bacterial effectiveness of the volatile oils in two in Syrian wide spread plants Micromeria rubestris L., Mentha viridis L. (Lamiaceae)

Abstract Background Camouflage of nasal dorsum, aesthetic augmentation and highlighting the dorsal aesthetic lines are essential elements in modern rhinoplasty. Numerous techniques have been utilized including deep temporal fascia, rectus abdominis fascia, and diced cartilage in fascia (DC-F). Despite their wide spread adoption, technical challenges remained, especially when utilized for aesthetic purposes. Objectives The paper details the use of fascia (F) and diced cartilage in fascia grafts (DC-F) for aesthetic dorsal refinement in primary and secondary cases. One of the main goals was to achieve ideal dorsal aesthetic dorsal lines rather than just volume augmentation. Methods We used grafts from the deep temporalis fascia (F) and rectus abdominis fascia (RF) in 4 configurations: 1) single layer, 2) double layer, 3) full length diced cartilage in fascia grafts (DC-F), and 4) partially filled – segmental DC-F grafts. Technical refinements included careful determination of dimensions and meticulously suturing to the dorsum at appropriately 10 points to prevent graft displacement. Results We report our experience: 146 clinical cases over 35 months from January 2017 to December 2019. The patients were divided for 4 groups depending on which type of graft was used. Conclusions Use of autogenous deep temporal fascia, rectus abdominis fascia, and diced cartilage in fascia (DC-F) to camouflage dorsal irregularities, to highlight dorsal aesthetic lines, and to aesthetically augment either the entire nasal dorsum or its individual parts. Optimization of cutting, stitching, filling the graft, careful fixation of these grafts on the nasal dorsum, significantly increases the predictability of these techniques and minimizes problems.

Method Analysis

Abstract. The purpose is to analyze the prevalence of obstetric and gynecological pathologies in a large dairy goat enterprise. Method. Analysis of data from veterinary registers of the enterprise, as well as histological examination of fetal membranes and determination of the biophysical profile of newborn goats were carried out. Results. The results obtained showed different distribution of obstetric and gynecological diseases among the Alpine goats in the conditions of a large industrial enterprise during the year. The results obtained showed that the general level of obstetric-gynecological diseases of goats by months of the year made up from 2.7 % to 100 % of the number of calves taken place with the most favourable conditions for obstetric-gynecological pathologies being June, July and September – 7.8 %, 4.1 % and 2.7 % respectively. A significant increase in the proportion of stillborn goats from their total number to 26.8 % and 26.3 % was observed in August and November, respectively. In winter and late autumn, there is a marked increase in retention of placenta, up to 8–10 %. In late spring and summer there is a seasonal decrease. The average number of goats in calving at this farm is 1.8 ± 0.43 goats with fluctuations by months of the year from 1.4 in January to 2.9 in August. The conducted histological and fetal membrane studies and determination of the biophysical profile of goats' calves showed a wide spread of fetoplacental insufficiency and changes in the placenta structure in the Alpine breed goats in the conditions of a large enterprise. Scientific novelty. The analysis of spread of obstetric-gynecological diseases of the Alpine breed goats in the conditions of the big enterprise has been carried out; the wide spread of fet-placental insufficiency among the uterine population has been confirmed by histological studies and the estimation of the biophysical profile of newborn baby goats.

Clostridioides Difficile Infection ◽

And Oxidative Stress

Clostridiodes difficile comprises a public-health threat that has been understudied in Colombia. Hypervirulent strains of C. difficile harbor multiple toxins, can be easily spread, and can have their onset of disease within healthcare facilities (HCFO) and the community (CO). Studies have shown that a disrupted microbiota (e.g., dysbiosis) may allow C. difficile infection (CDI). It has been suggested that dysbiosis prevents colonization by the anaerobic eukaryote Blastocystis, possibly due to an increase in luminal oxygen tension. No study has found co-occurrence of CDI and Blastocystis. Therefore, we aimed to determine the frequencies of C. difficile and Blastocystis infection/colonization in 220 diarrheal fecal samples. Molecular detection by PCR for both microorganisms was performed, with descriptive analyses of four variables (CDI detection, determination of C. difficile toxigenic profiles, Blastocystis detection, and patient site of onset). We demonstrate a significant association between the presence of Blastocystis and CDI, with coinfection found in 61 patients, and show a high frequency of CDI among both HCFO and CO groups. Our results of coinfection frequencies could support hypotheses that suggest Blastocystis can adapt to dysbiosis and oxidative stress. Further, the presence of toxigenic C. difficile occurring outside healthcare facilities shown here raises the alarm for community wide spread.

We report the isolation and determination of the essential oil composition from the leaves and rhizomes of Polianthes tuberosa (P. tuberosa), Polianthes sessiliflora (P. sessiliflora) and Polianthes longiflora (P. longiflora) species. These essential oils were extracted using supercritical CO2 extraction method, and their structures were characterised by GC-FID and GC/MS approaches. Methyl 2-aminobenzoate, isoeugenol, 5-octadecene, benzyl benzoate, 1-nonadecene, and diisobutylphthalate were identified as their major chemical compositions. Moreover, the anti-cancer activity of the total essential oils from these three Polianthes species was evaluated against five cancer cell lines.
