A investigação das atividades sociais e culturais dos intelectuais em redes sociais virtuais e seu impacto na cultura política estudantil
The present research is an applied one in terms of goals and in terms of the nature and type of study as a qualitative research and is an interpretative study that uses phenomenological research strategy to explain and interpret the essence of experience from the phenomenon of intellectuals’ social and cultural activities in virtual social networks and deep knowledge of this phenomenon on students' political culture. The results show that the role of intellectuals as conscious people and awakened conscience of society, whether in civil institutions and non-political social organizations, or in the state of belonging to political parties and political organizations, generally as individuals belonging to a social stratum, in some form it affects the political culture of the community, and contributes in the dynamics and awakening of the students' social and political consciousness, ultimately to the formation of national thought and feelings.La presente investigación es aplicada en términos de objetivos y en términos de la naturaleza y tipo de estudio como una investigación cualitativa y es un estudio interpretativo que utiliza una estrategia de investigación fenomenológica para explicar e interpretar la esencia de la experiencia del fenómeno de los intelectuales. y actividades culturales en redes sociales virtuales y conocimiento profundo de este fenómeno en la cultura política de los estudiantes.

Effects of wheat bran replacement with pomegranate seed pulp on rumen fermentation, gas production, methanogen and protozoa populations of camel and goat rumen using competitive PCR technique: An in vitro study
BackgroundMicrobial populations in the rumen play an essential role in the degradation of Cellulosic dietary components and in providing nutrients to the host animal.ObjectiveThis study aims to detect the effect of pomegranate seed pulp (PSP) on rumen fermentation, digestibility and methanogens and the protozoa population (by competitive polymerase chain reaction [PCR]) of the camel and goat rumen fluid.Materials and methodsPSP was added to the experimental treatments and replaced by wheat bran (0%, 5% and 10%). Rumen fluid was collected from three goats and two camels according to the similarity of sex, breed, origin and time and used for three gas production studies. DNA extraction was performed by the RBB + c method, the ImageJ programme calculated band intensities (target and competing DNA), and line gradients were plotted based on the number of copies and intensity.ResultsOur result showed that diets did not significantly affect the methanogen and protozoa population. Animal species affected microbial populations so that both populations in camels were less than goats. The production of gas and volatile fatty acids was not affected by diets. These two parameters and NH3 concentration and methane production in goats were higher than in camel. The pH of digested dry matter and microbial protein in camels was higher than in goats.ConclusionsTherefore, the competitive PCR technique is an effective method for enumerating rumen microbiota. This supplementation can be considered a strategy to achieve performance and environmental benefits.The competitive PCR technique is an effective method for the enumeration of rumen microbiota.This supplementation can be considered a strategy to achieve performance and environmental benefits.imag

Microbiological Profile of Corneal Ulcers at a Tertiary Referral Center
The aim of this study was to describe patient demographics, microbiological profile, and antibiotic susceptibility of corneal ulcer at a tertiary referral center to improve and optimize diagnosis and treatment of this potentially blinding entity and to reduce antibiotic misuse. Detailed external and slit-lamp bio-microscopic examination of 123 consecutive patients with suspected corneal ulcer was performed at an ophthalmology clinic. Corneal scraping was carried out under slit-lamp bio-microscopy. The obtained material was inoculated on culture media and smeared on a slide for Gram's staining for morphological identification of bacteria and fungus. For samples that developed colony in culture media, antibiotic susceptibility testing was performed. In a significant percentage of patients (72%) neither bacterial agents nor fungi were the cause of corneal ulcer. Of the 34 culture-proven corneal ulcers, in 79% of the cases, bacteria were detected while in 21% of cases, fungi were found. Of the 27 bacterial corneal ulcers, the majority were (67%) caused by Gram-positive bacteria, of which 50% were Streptococcus pneumoniae, and in the Gram-negative bacterial corneal ulcers, most of the cases (44%) were caused by Pseudomonas aeruginosa. In the antibiotic susceptibility report, Streptococcus pneumoniae, Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli were resistant to Cotrimoxazole (TS), Streptococcus pneumoniae to Erythromycin (E), Staphylococcus aureus to Peniciline (PG), Pseudomonas aeruginosa to Ceftriaxone (CRO) and Nitrofurantoin (NI), and finally, Escherichia coli to Gentamicin (GM). In conclusion, in a significant number of the patients neither bacterial agents nor fungi were offending microorganisms and bacteria were the most common agent of microbiological corneal ulcer, found in 79% of culture-proven corneal ulcers, followed by fungus, found in 21% of culture-proven corneal ulcers

Evaluation of Vitamin D3 and D2 Stability in Fortified Flat Bread Samples During Dough Fermentation, Baking and Storage
Purpose: Vitamin D, a fat-soluble secosteroid, has
a significant role in bone metabolism and helps calcium absorption in the body.
Since vitamin D concentration is altered in fortified foods and dietary
supplements, the actual amount of vitamin D may differ from the label value.
Methods: In this study, the concentrations of vitamin D2
and D3 of fortified bread sample were analytically determined. For
this purpose, dough or homogenized bread sample was saponified using potassium
hydroxide solution (30%, w/v) at 80°C, and the saponified analytes were
extracted into n-heptane followed by liquid-liquid extraction. Then n-heptane
fraction was evaporated to dryness and the sample was reconstituted in
methanol. The effect of different parameters was evaluated by one variable at
one-time strategy.
Results: The analytes
concentrations were evaluated in dough fermentation, baking and storage steps.
The effect of temperature in dough fermentation and baking was evaluated at the
range of 5-30 and 200-250°C, respectively. Also, the fermentation time was
studied in the range of 0-120 min. The analytes concentrations were followed
for 1 to 5 days after baking. The results indicated that dough fermentation
temperature has no significant effect on the concentration of the analytes. On
the other hand, when the dough fermentation time and baking temperature are
increased, the analytes concentrations are decreased. Also, the storage
duration of the spiked bread samples decreased the analytes concentrations
after one day.
Conclusion: Based on the obtained
results, baking the dough at high temperatures lead to decrease in vitamin
levels
ERYTHROCYTE MEMBRANE FATTY ACIDS IN MULTIPLE SCLEROSIS PATIENTS AND HOT-NATURE DIETARY INTERVENTION WITH CO-SUPPLEMENTED HEMP-SEED AND EVENING-PRIMROSE OILS
The risk of developing multiple sclerosis (MS) is associated with increased dietary intake of saturated fatty acids. For many years it has been suspected that this disease might be associated with an imbalance between unsaturated and saturated fatty acids. We determined erythrocyte membrane fatty acids levels in Hot nature dietary intervention with co-supplemented hemp seed and evening primrose oils in multiple sclerosis patients. To determine the erythrocyte membrane fatty acids levels and correlate it with expanded disability status scale (EDSS) at baseline after 6 months intervention in MS patients by gas chromatography, in this double blind, randomized trial, 100 RRMS patients with EDS
Expanding the mutational landscape and clinical phenotype of the YIF1B related brain disorder
The clinical and genetic spectrum of autosomal-recessive TOR1A-related disorders.
In the field of rare diseases, progress in molecular diagnostics led to the recognition that variants linked to autosomal-dominant neurodegenerative diseases of later onset can, in the context of biallelic inheritance, cause devastating neurodevelopmental disorders and infantile or childhood-onset neurodegeneration. TOR1A-associated arthrogryposis multiplex congenita 5 (AMC5) is a rare neurodevelopmental disorder arising from biallelic variants in TOR1A, a gene that in the heterozygous state is associated to torsion dystonia-1 (DYT1 or DYT-TOR1A), an early-onset dystonia with reduced penetrance. While 15 individuals with TOR1A-AMC5 have been reported (less than 10 in detail), a systematic investigation of the full disease-associated spectrum has not been conducted. Here, we assess the clinical, radiological and molecular characteristics of 57 individuals from 40 families with biallelic variants in TOR1A. Median age at last follow-up was 3 years (0-24 years). Most individuals presented with severe congenital flexion contractures (95%) and variable developmental delay (79%). Motor symptoms were reported in 79% and included lower limb spasticity and pyramidal signs, as well as gait disturbances. Facial dysmorphism was an integral part of the phenotype, with key features being a broad/full nasal tip, narrowing of the forehead and full cheeks. Analysis of disease-associated manifestations delineated a phenotypic spectrum ranging from normal cognition and mild gait disturbance to congenital arthrogryposis, global developmental delay, intellectual disability, absent speech and inability to walk. In a subset, the presentation was consistent with fetal akinesia deformation sequence with severe intrauterine abnormalities. Survival was 71% with higher mortality in males. Death occurred at a median age of 1.2 months (1 week - 9 years) due to respiratory failure, cardiac arrest, or sepsis. Analysis of brain MRI studies identified non-specific neuroimaging features, including a hypoplastic corpus callosum (72%), foci of signal abnormality in the subcortical and periventricular white matter (55%), diffuse white matter volume loss (45%), mega cisterna magna (36%) and arachnoid cysts (27%). The molecular spectrum included 22 distinct variants, defining a mutational hotspot in the C-terminal domain of the Torsin-1A protein. Genotype-phenotype analysis revealed an association of missense variants in the 3-helix bundle domain to an attenuated phenotype, while missense variants near the Walker A/B motif as well as biallelic truncating variants were linked to early death. In summary, this systematic cross-sectional analysis of a large cohort of individuals with biallelic TOR1A variants across a wide age-range delineates the clinical and genetic spectrum of TOR1A-related autosomal-recessive disease and highlights potential predictors for disease severity and survival
