Published: October 2023

Ferns are significantly dominant in Indonesia. The waterfall area is one of the ferns habitats. This study aims to determine the diversity index of ferns species in the Tourism Area of Sekar Pudak Sari Waterfall Wonosalam District, Jombang Regency, East Java. This research was exploratory, descriptive. Data collection uses a single plot measuring 20x20 m at 500 masl, 700 masl, and 900 masl. Each observation plot has a sub-plot with a size of 2x2 m. Data analysis used the Shannon-Wiener diversity index (H'), the taxonomic diversity index (Δ), and dominance (Δ*). The exploration results found 28 species from 11 families, 6 epiphytes, and the rest terrestrial. The taxonomic diversity index in plot 1 was 23.36 (low category), while plots 2 and 3 were 30.58 and 31.66 (medium category). This shows that the environment in the three plots is classified as stable, as indicated by the presence of ferns at various taxonomic levels. The highest dominance diversity index (Δ*) was 2.8 in Plot 2, while Plots 1 and 3 were 2.7 (low category). The total number of individual ferns found influenced the difference in the diversity index. The ferns found in the three plots were relatively few, indicating that the environment was classified as less stable. The Shannon-Wiener diversity index (H') in the three plots was 2.9 (medium category), indicating that the distribution pattern of ferns in the environment was balanced. The Sekar Pudak Sari Waterfall Tourism Area is a suitable habitat for the growth of ferns, so conservation efforts need to be made to maintain a balance of species and stabilize the ecosystem.

Authors: Yulinda Putri Risma , Bashri Ahmad
Published: October 2023

Rhizophora is a genus of mangrove plants that dominates the Banyuurip Mangrove Center. This plant certainly has an anatomical structure as a form of adaptation to high salinity environments. The purpose of this study was to describe the anatomical characteristics of the leaves of the three Rhizophora species as an adaptation form of mangrove plants in the Banyuurip Mangrove Center and the anatomical variations of the leaves between species. This type of research was descriptive observational in the form of leaf anatomy observations using the whole mount method for longitudinal incisions and the paraffin method for transverse incisions. The results showed that there were anatomical variations among the three Rhizophora species in the Banyuurip Mangrove Center including epidermal cell size, number of epidermal cells, cork warts, number of hypodermis cell layers, hypodermis cell size, stomata size, number of stomata, stomata index, and stomata density. The anatomical characteristics of the leaves of the three Rhizophora species which act as a form of adaptation to mangrove plants are the presence of hypodermis tissue which functions to store water and salt to remove salt content in plants when they abort their leaves, low density of stomata and the presence of cuticles on the adaxial surface of leaves which play a role in reducing the rate of transpiration thus maintaining water to support plant development in saline conditions, cork warts which function as a medium for expelling salt on leaves.

Published: October 2023

The study aimed to investigate the reality and challenges of the special education services provided to students with attention deficit hyperactivity disorder (ADHD) in primary schools in the Kingdom of Saudi Arabia from the point of view of their teachers. By examining the perspectives of these educators, the research seeks to identify gaps, barriers, and areas for improvement in order to enhance the educational experience and outcomes for students with ADHD in primary schools. The study used a mixed-method approach, with a questionnaire distributed to 108 special education teachers and semi-structured interviews with conducted with four of those teachers. The mean, standard deviation, and ANOVA were among the techniques used in this study’s data analysis. The study used coding to perform an interpretive analysis on the qualitative data. The study concluded that the reality of special education services provided to students with ADHD is not at the desired level. The results also demonstrated that there are some obstacles facing the provision of special education services to students with ADHD in primary schools, including the lack of clarity in the referral procedures, the concealment by parents of some important information about the child’s condition, and the lack of awareness of general education teachers of disorders. The study suggested the need to adopt special programmes for ADHD in primary schools, the existence of clear procedural guides, and to raise awareness of ADHD through intensive in-service training for special education teachers.

La pandemia del COVID 19 ha traído profundas transformaciones a la sociedad, cuyas consecuencias aún están por verse. Más allá de las obvias y dolorosas secuelas en la salud pública, los medios de comunicación debieron enfrentar retos y dificultades súbitas para las que no estaban preparados.  En este ensayo se retoma la tradición de los períodos históricos de la televisión desde la teoría de la paleo y la neotelevisión de Umberto Eco, pasando por las nociones de post-televisión (Missika, 2006; Piscitelli, 1998; Ramonet, 2002; Imbert, 2007, 2008), metatelevisión (Scott, 1987; Carlon, 2006) e hipertelevisión (Scolari, 2008; Gordillo, 2009) para sugerir la aparición de una nueva etapa de la televisión en período pandémico y postpandémico: la hipo-televisión.  La hipo-televisión es una etapa de recursividad y austeridad.   pero también por una mayor implicación de los espectadores y una mayor cercanía con las celebridades. Ante la posibilidad del fin de la pandemia, sin embargo, la duración de este período es aún impredecible.

Published: October 2023

Background. Migraine is a primary headache disorder described by episodic attacks that can progress to chronic migraine. Preventive treatment of anti-calcitonin gene-related peptide monoclonal antibodies (anti-CGRP mAbs) is currently being widely investigated worldwide.Materials and methods. A total of 85 patients with migraine were enrolled in a retrospective study conducted in 2019-2021. Demographic and clinical data were collected and analyzed. Subjects were divided into groups by migraine course: chronic migraine (CM) and episodic migraine (EM), and according to the medicine used (erenumab, fremanezumab). Treatment efficacy was assessed at 3 and 6 months after the start of treatment. A reduction of >50% in monthly headache days (MHDs) was considered a good response. Statistical analysis was performed using IBM SPSS statistics 27.0, the χ² test of homogeneity, Fisher’s exact, Student’s t, and Mann-Whitney tests.Results. Of the 85 migraine patients, 75 (88.2%) were women. EM was diagnosed in 33 (38.8%) and CM in 52 (61.2%) patients. After treatment, the number of MHDs was significantly reduced in both anti-CGRP mAbs therapy groups (p<0.001). The response to anti-CGRP mAbs was similar between the EM and CM groups. A slightly better response was achieved with fremanezumab than erenumab (83.3% vs. 73.1% at 3 months; 83.3% vs. 65.7% at 6 months), but the difference was not significant (p=0.541; p=0.149). In 24 (58.5%) patients initially given 70 mg erenumab, after a median follow-up of 3 months (interquartile range: 2-6) it was decided to increase the dose of erenumab to 140 mg due to insufficient effect. The initial dose was increased more often in patients with chronic migraine (p=0.027).Conclusions. Erenumab and fremanezumab are equally effective and equivalent for both migraine types. It was observed that more than half of the patients required a dose increase when treated with erenumab 70 mg, especially in CM group.
Acute cerebral edema: a lethal neurological complication in a patient with COVID-19 infection. Case report and literature review
Authors: Puodžiūnaitė M. , Sadeckaitė R. , Čikotienė A.
Published: October 2023

Introduction. COVID-19 can damage the nervous system by direct viral damage to the neural cells or by immunopathology. More serious medical conditions such as cerebral edema, neuronal degeneration, encephalitis, acute disseminated encephalomyelitis, Guillain-Barre syndrome, Bickerstaff’s brainstem encephalitis, Miller-Fisher syndrome, polyneuritis, toxic encephalopathy, and stroke can occur.Case report. We report a case of a 40-year-old patient with previous history of hypertension and no other chronic disease who was admitted to the hospital with respiratory distress due to SARS-CoV-2-induced bilateral pneumonia. A few days later, he developed worsening respiratory function with an acute seizure episode. Head CT scan revealed subarachnoid hemorrhage with diffuse cerebral edema as a lethal neurological complication, possibly secondary to COVID-19.Discussion. COVID-19 induces CNS damage through various mechanisms including ACE-2 receptor damage, cytokine storm syndrome, secondary hypoxia, blood-brain barrier disruption, and neuroinflammation. Neurological symptoms correlate with the severity of COVID-19 disease and may range from asymptomatic infection to severe and lethal forms. Acute cerebral edema, as illustrated by our case, may result from a combination of diffuse en dothelial dysfunction, cytokine release syndrome, and hypoxic damage from pulmonary dysfunction.
Role of microglia in the pathogenesis of multiple sclerosis and links to immunomodulatory therapy
Authors: Valiukevičius P. , Liutkevičienė R. , Balnytė R.
Published: October 2023

Multiple sclerosis is a chronic autoimmune disease of the central nervous system. Multiple sclerosis causes demyelination, impaired nervous system function, and eventually neurodegeneration. Microglia are cells of the central nervous system that develop from yolk sac macrophages during embryogenesis. These cells perform important functions in the development of the central nervous system and the retina, in the formation of synapses, protect against pathogens, and are involved in the removal of damaged structures. In response to environmental factors, microglia can acquire an inflammatory or anti-inflammatory phenotype. Microglia also play an important role in the pathogenesis of multiple sclerosis, and these cells are thought to be involved in both demyelination and remyelination processes. Microglial cells phagocytose harmful myelin remnants, promote remyelination, and control the proper response of peripheral immune cells, but disruption of these functions can lead to demyelination and neurodegeneration. Many of the disease-modifying drugs used to treat multiple sclerosis also affect microglial cells and inhibit their inflammatory response. Currently, new drugs are being researched that could be used to treat multiple sclerosis promoting the transition of microglia to an anti-inflammatory phenotype. The latest advanced cell therapy drugs have a broader spectrum of action – they inhibit inflammation, promote angiogenesis, perform trophic function, and inhibit oxidative damage.

Background: Omega3 is a group of fatty acids which is essential and of great importance to the human body, they cannot be produced on their  own, so it must be obtained by following diets that include foods rich in them. Omega 3 is nowadays one of the most desirable components of oils because of its nutritional and functional properties. Through its various processes in cellular metabolism, its therapeutic actions in numerous chronic inflammatory and autoimmune disorders have been identified, gene expression, and signal transduction. Numerous studies have confirmed that acne, psoriasis, and inflammatory skin conditions including atopic dermatitis can all be managed with omega 3.

Objective: The review's objective is to provide a brief scientific overview of this condition, which has recently become widespread used in the treatment of skin diseases.

Conclusion: The effects of "3 PUFA" in skin illnesses are only seldom studied in research and clinical trials, but prior studies analyzing immune cells predict that these fatty acids will have a wide range of positive benefits. Additionally, there are few findings on keratinocytes, which are thought to make up a significant portion of the epidermis' cells. Future studies should clarify the complete role keratinocytes play in the skin. since the prevalence of inflammatory skin conditions and cancers is rising at the moment, clinical trials in the future on "3 PUFAs" in dermatological sectors are likely to provide us with useful knowledge for the routine clinical management of skin problems.

Keywords: Polyunsaturated fatty acids, "PUFAs," omega-3, psoriasis, skin.

Background: Enhancing the optical characteristics of nano-silicon carbide and polyvinyl alcohol films is thought to be crucial for obtaining the semiconductor with the lowest energy gap for applications in electrical devices, digital displays, and sensors.

Materials and Methods:  Poly vinyl alcohol and silicon carbide's optical properties were examined. A pulsed laser with a 532 nm wavelength is used to create these nanoparticles into widespread nanoparticles in two environments (water and vinyl alcohol). Polyvinyl alcohol  nanocomposite was created by spin coating silicon carbide particles with the weight fractions 0.90%, 0.91%, 0.93%, and 0.95%. Fourier spectroscopy was used to locate the functional groups based. Techniques FESEM were used to analyze the surface composition and nanoparticle dispersion on the membrane-surface of the nanocomposite. using spectroscopy UV-Vis used to record the absorbance spectrum in the range of (200-800) nm for ultraviolet radiation.

 Results: The direct energy gap (5.585, 5.310, 5.480, 4.986, 4.800) eV and the indirect (5.006, 4.880, 4.916, 4.683, 4.490) eV and Urbach energy (2.38, 2.45, 2.94, 2.74, 3.67) eV were calculated.for the samples by ratio, as shown in Table No. 1.

Conclusion: By investigating the optical characteristics of nanoparticles, such as their extinction and absorption coefficients, direct and indirect optical energy gaps, and Urbach energies .increase in extinction and absorption coefficients Urbach energy when adding nano carbide to polyvinyl alcohol, results show narrowing of the direct and indirect energy gaps.

Published: October 2023

An experiment was laid out to study the response of green gram (Co.2) to phos phorus application under irrigation. Phosphorus application through soil increased the plant height on 45th day and at harvest but there was no difference between P levels tested. Foliar application of P decreased the height. Leaf area index and the yield com- ponents such as number of pods per plant, number of seeds per pod and thousand grain weight were not influenced by P application. Neither grain yield nor stalk yield was aff- ected by P application. For a short duration variety like Co.2. P application produces little response in a soil with medium available P status.
