Published: November 2022

O objetivo deste estudo foi mostrar a aplicabilidade de sistemas de ecobatimetria multifeixe para identiï¬car feições geológicas, geomorfológicas e antrópicas submersas no fundo do reservatório de São Simão - GO. O reservatório foi formado pelo represamento do rio Paranaíba e está inserido no contexto da bacia do Paraná. Ele ocupa uma área de 677,57 km² e possui um volume de acumulação de 12540 hm3. O levantamento batimétrico foi realizado utilizando dois diferentes modelos de multifeixe de alta freqÃ¼ência e alta resolução, o ODOM MB2 e o RESON 7125. Aquisição, controle de qualidade e processamento dos dados foi realizado com os softwares Teledyne PDS 2000 e QINSy, respectivamente, para redução das sondagens ao mesmo datum vertical e remoção de dados espúrios. Para a geração dos mapas, utilizou-se o software ArcGIS, e a interpolação dos dados foi realizada por meio da ferramenta "topo to raster", desenvolvida para modelar bacias hidrográï¬ cas. No ArcGIS, também foi possível realçar as feições localizadas com ferramentas de sombreamento e com o método curvature. Como resultado, a batimetria multifeixe apontou uma serie de feições, nas quais se destacaram lineamentos, características do leito do canal e dos tributários, barras longitudinais, pontes submersas e pivôs de irrigação, mostrando que a batimetria multifeixe constitui uma ferramenta extremamente útil para o mapeamento e individualização de feições submersas.

Published: November 2022

Na história recente de ocupação da Amazônia, as estradas sempre tiveram papel estratégico para impulsionar a perda da cobertura florestal. No entanto, atualmente, a derrubada da floresta ocorre em áreas inferiores a 25 ha. Para dar conta dessa nova dinâmica, o Instituto Nacional de Pesquisas Espaciais (INPE) criou o sistema DETER-B (Sistema de Detecção de Desmatamento e Alterações na Cobertura Florestal em Tempo Quase Real), que utiliza as imagens do Satélite Sino-Brasileiro de Recursos Terrestres (CBERS-4) e o sensor AWiFS, do satélite Indian Remote Sensing Satellite (IRS), com resolução espacial de 64 m e 56 m, respectivamente. Esse sistema mapeia desmatamento e alterações na cobertura florestal a partir de áreas de 3 ha. Nesse sentido, o trabalho objetivou analisar a relação entre o novo padrão de desmatamento e a alteração da cobertura florestal e a distância das estradas na mesorregião do Sudoeste Paraense, ao longo dos anos de 2012 a 2015, utilizando os dados do sistema de monitoramento de florestas DETER-B. Como resultado, foi identificado que as classes de Desmatamento e Degradação concentraram-se nos primeiros 2.500 m de distância das estradas. Ademais, constatou-se que os polígonos das classes mapeadas são majoritariamente inferiores a 1  km².

Published: November 2022

This study aimed to determine the seasonal effect on the performance of pigs reared in open-barn housing in Thailand. This retrospective study was performed using two years of recorded pig perfor-mance, including average birth weight, litter size, percentage of born alive and dead piglets, weaning weight, average daily gain (ADG), percentage of weaned alive and dead piglets and meteorological data. Data were grouped based on 3 different seasons: winter, summer and the rainy season, and the differences were compared. The highest temperature–humidity index (THI) was found during summer (85.3 ± 0.2) and the THI of the rainy season was higher than that in winter (between 82.3 ± 0.2 and 77.2 ± 0.4) (p < 0.05). The piglet growth performance was affected by season (p < 0.05). The weaning weight of piglets in the rainy season was higher than that in winter but not different from that in sum-mer. The highest ADG was observed in the rainy season. In summary, growth performance of suckling pigs reared in open-barn housing in Thailand was affected by the season. The optimal climate promot-ing growth of nursery pigs was determined to be the rainy season.
Need satisfaction and collective efficacy in undergraduate blog-driven classes: A structural equation modelling approach
Authors: Tilak Shantanu , Glassman Michael , Peri Joshua , Xu Menglin , Kuznetcova Irina , Gao Lixiang
Published: November 2022

This paper investigates how psychological needs spurring self-determined motivation relate to collective efficacy for flourishing in online learning communities. Self-determination theory posits individuals experience intrinsic motivation to flourish at educational tasks because of targeted satisfaction of the three psychological needs: autonomy, relatedness, and competence. However, studies conducted to investigate collective, technology-assisted learning processes suggest competence and relatedness may play a pivotal role in online community engagement and knowledge-sharing. Moreover, informal gaming experiences may mirror the collaborative skills needed in online educational/professional communities. These insights suggest confidence in one’s abilities to contribute to a community, the perception of a strong, supportive social culture in the online classroom, and informal online experiences may lead to self-determined motivation enabling agents in distributed, technology-assisted classrooms to collectively flourish. Little work has been done to examine effects of need satisfaction on collective efficacy in using online technologies. To fill this research gap, we used structural equation modelling to investigate perceptions of 636 undergraduate students enrolled in classes within an education department at a midwestern university employing weekly asynchronous blogging. Our results suggest students’ experience with multiplayer gaming, and need satisfaction towards competence and relatedness correlate with higher collective efficacy in technology-assisted classrooms employing discussion forums.
Implications for practice or policy:

For instructors, student usership and design can spur motivation in online classrooms.
For researchers, understanding student perceptions of collaboration using technology can help understand how to design better technology-assisted classrooms.
The design of collaborative online educational communities should focus on creating positive social cultures and fostering competence for students.
Teaching English online in higher education: Understanding the social climate of online academic English courses
Authors: Waluyo Budi , Min Feng , Castillo Vanessah V.
Published: November 2022

This study examined the social climate of fully synchronous online English classrooms and its effects on students’ learning outcomes in a mixed-methods design, engaging 196 first-year non-English major students experiencing their first fully synchronous online English classes on Zoom in one academic term (12 weeks), taught by foreign lecturers. The results reveal a very positive learning experience with seven factors contributing to the social climate of the online English classrooms. Gender did not affect students’ perceptions and learning experiences, but English proficiency levels did, with a medium effect size. The social climate was a predictor of online English learning outcomes with a substantial effect size. Individual insights were extracted from the qualitative data.
 
Implications for practice or policy:

Online English courses should provide the same learning quality as in a face-to-face environment by enhancing the seven factors constructing a positive online English classroom climate.
Educational policymakers should emphasise building positive social climates in online classrooms as it will lead to both better learning outcomes and experiences.
Teachers may be encouraged to develop the skills students need to recognise and manage emotions, establish and maintain relationships and achieve positive goals in online English learning.

Published: November 2022

Cordyceps sinensis (C. sinensis) is a kind of traditional Chinese medicine commonly used to protect renal function and relieve kidney injury. This study aimed to reveal the renal protective mechanism of C. sinensis in renal ischemia–reperfusion injury (RIRI). First, we obtained 8 active components and 99 common targets of C. sinensis against RIRI from public databases. Second, we have retrieved 38 core targets through STRING database analysis. Third, Gene Ontology analysis of 38 core targets is indicated that C. sinensis treatment RIRI may related hormone regulation, oxidative stress, cell proliferation, and immune regulation. Kyoto Encyclopedia of Genes and Genomes enrichment analysis of 38 core targets is indicated that C. sinensis treatment RIRI may involve in PI3K–Akt, HIF-1, and MAPK signaling pathways, as well as advanced glycation end product (AGE)–receptor for AGE (RAGE) signaling pathway in diabetic complications. Lastly, molecular docking was used to detect the binding activity and properties of active components and core target using molecular docking. And the results showed that eight active components of C. sinensis had low affinity with core targets. In conclusion, C. sinensis may improve RIRI by regulating oxidative stress and immunity through PI3K–Akt, HIF-1, and MAPK pathways.
Highly robust causal semiparametric U-statistic with applications in biomedical studies
Authors: Yin Anqi , Yuan Ao , Tan Ming T.
Published: November 2022

With our increased ability to capture large data, causal inference has received renewed attention and is playing an ever-important role in biomedicine and economics. However, one major methodological hurdle is that existing methods rely on many unverifiable model assumptions. Thus robust modeling is a critically important approach complementary to sensitivity analysis, where it compares results under various model assumptions. The more robust a method is with respect to model assumptions, the more worthy it is. The doubly robust estimator (DRE) is a significant advance in this direction. However, in practice, many outcome measures are functionals of multiple distributions, and so are the associated estimands, which can only be estimated via U-statistics. Thus most existing DREs do not apply. This article proposes a broad class of highly robust U-statistic estimators (HREs), which use semiparametric specifications for both the propensity score and outcome models in constructing the U-statistic. Thus, the HRE is more robust than the existing DREs. We derive comprehensive asymptotic properties of the proposed estimators and perform extensive simulation studies to evaluate their finite sample performance and compare them with the corresponding parametric U-statistics and the naive estimators, which show significant advantages. Then we apply the method to analyze a clinical trial from the AIDS Clinical Trials Group.

Published: November 2022

Objectives

The study aimed to determine the phytochemical profile and safety of the aqueous extract of Pleurotus tuber regium using laboratory animal model.

Methods

The pulverized sample was macerated with water and allowed to stand for 24 h, then filtered. Preliminary qualitative phytochemical screening was carried out on the crude extract and LD50 determination was done using standard procedures. Haematological and serum biochemical parameters to assess the kidney and liver functions were carried out using standard methods.

Results

The phytochemical screening revealed the presence of alkaloids, cardiac glycosides, saponins, phenolic compounds, tannins, steroids, carbohydrates, flavonoids and terpenoids. However, anthraquinones were observed to be absent in the extracts. The LD50 of the extract was found to be greater than 5,000 mg/kg when administered orally with no physical signs of toxicity and death over the 14-day period. There was no significant (p>0.05) increase in the level of serum alanine aminotransferase, aspartate transaminase, alkaline phosphatase, blood urea nitrogen and creatinine (p<0.05) when compared to the control group. There was a significant (p<0.05) increase in the total white blood cells of the mice administered with P. tuber-regium.

Conclusions

This study showed that P. tuber-regium (Fr.) Singer does not possess toxic principles, hence, the wide safety margin observed in the mice.

Published: November 2022

Nowadays, polarization division multiplexing (PDM) employing different states of polarizations (SOP) is a prominent candidate to offer high capacity and improved performance. However, the incorporation of PDM in indoor wireless optical communication (WOC) systems is limited to horizontal and vertical SOPs only. Therefore, in this research article, a cost-effective and high capacity 90 Gbps non-return to zero (NRZ) line coding based 18 channels VLC system is presented by incorporating red–green–blue laser diodes (RGB LDs). Performance investigations of different SOPs such as SOP 0°, SOP 45°, and SOP 90° are carried out at diverse VLC link distances in terms of log BER and Q factor. Results revealed that the proposed VLC system can successfully cover the 6 m distance and red LD together with SOP0 is found to be the highest performing.

Objectives

Congenital generalized lipodystrophy (CGL) is a group of rare autosomal inherited diseases characterized by a widespread loss of adipose tissue. The main purpose of this study was to evaluate the features of Chinese patients with CGL2.

Methods

Three patients diagnosed with CGL2 from our center were reviewed. Data on clinical features, results of laboratory analyses, and previous treatments were retrospectively collected. This study also reviewed studies that reported patients diagnosed with CGL2 in the last 30 years.

Results

All patients presented a lack of subcutaneous fat, hypertriglyceridemia, reversed triangular faces, acanthosis nigricans, and hepatomegaly within the first six months of life. All three patients developed splenomegaly, and mental retardation in later life. Dietary control dramatically lowered triglyceride levels in all patients. One patient presented with diabetes mellitus at 1 year-old. Although combined therapy with low fat diet and metformin maintained normal levels of blood lipid and glucose, this patient developed hypertrophic cardiomyopathy at the age of three. By a literature review on all Chinese cases with CGL2, it is known that classic manifestations such as hypertriglyceridemia, hepatomegaly and diabetes mellitus can occur shortly after birth, and early diagnosis and treatment can improve quality of life. In this cohort, the most frequent variations are c.782dupG and c.974dup in the BSCL2 gene. However, the same genotype may have different clinical phenotypes in patients with CGL2.

Conclusions

This study not only described the clinical and genetic features of three patients with CGL2 in China, but also reviewed literature about CGL2 around the world.
Paradise lost: Cognitive grammar, nature, and the self in Diane Seuss’s ekphrastic poetry
Authors: Panagiotidou Maria-Eirini
Published: November 2022

Diane Seuss’s ekphrastic poetry collection Still Life with Two Dead Peacocks and a Girl is a celebration of life and death, imagination and reality, stillness and movement. This paper focuses on the first poem of the collection to investigate the relationship between the poetic persona and the landscape surrounding her. I employ central principles of cognitive linguistics as applied in the field of stylistics to discuss the manifestation of her mind style and examine how she constructs and situates herself in the environment. Drawing on Langacker’s notion of construal, I analyze the perspective and the degree of specificity of the descriptions. I also trace the extensive use of the container image schema that underlies the semantics of the poem. The paper demonstrates that despite her assumed idyllic existence, the poetic voice’s ornate descriptions of nature conceal a sense of uneasiness and confinement and the highly granular lexical choices and figurative expressions reveal her anthropocentric view of the environment. This gives rise to her feelings of alienation while the presence of the container image schema reinforces her sense of confinement. From an ecostylistic perspective, the analysis demonstrates how an anthropocentric view may manifest itself linguistically, highlighting textual features of anthropocentric narratives.
Materialographic sample preparation of ancient copper materials
Authors: Cloeren H.-H.
Published: November 2022

The metallographic preparation of samples from classical antiquity requires the use of very gentle preparation techniques. On the one hand, this is necessary since the samples provided are often very small and on the other hand, because the remaining sample material can be inserted back into the original object.

Both sample preparation and microstructural evaluation may offer insights into the manufacture of the objects, for example whether casting, heat treatment or reshaping had taken place. In addition, corrosion products on the sample surfaces can be characterized. The results of the metallographic preparation of three different ancient copper objects are presented: 1. A bronze vessel from Gordion. 2. Bronze roof tiles from Caligula’s Nemi ships. 3. Roman copper nails from Carnuntum.
Characterization of toothpastes for fluorine and other elements by INAA and ICP-OES
Authors: Wasim Mohammad , Tariq Arfan , Qureshi Rashid Nazir , Shafique Munib Ahmed
Published: November 2022

Fluoride toothpastes have made a significant contribution towards oral hygiene. This study proposes instrumental neutron activation analysis (INAA) as a suitable technique for determining fluorine in toothpastes. The method involved a 10 s irradiation, followed by 10–20 s decay, and counting for 10 s, using a pneumatic system and high purity germanium detector. All irradiations were performed at miniature neutron source reactor with thermal neutron flux 1 × 1012 cm−2 s−1. Since Na was present in all toothpastes, the quantification of fluorine required correction for 23Na(n,α)20F threshold reaction. Fluorine determination was validated by analysing the samples by ion chromatography. All toothpastes were also analysed for other elements by k
0-INAA and ICP-OES. Both techniques quantified 28 elements including Al, As, Ba, Ca, Ce, Cl, Co, Cr, Cu, F, Fe, Hf, K, La, Mg, Mn, Na, P, S, Sb, Sc, Si, Sm, Sn, Sr, Ta, Ti and Zn. This study, categorized toothpastes in five groups based on concentrations of Ca, P and Ti.

Authors: Villabona-González Silvia Lucía , López-Cardona Yury Catalina
Published: November 2022

Kellicottia bostoniensis (Rousselet, 1908) es un rotífero planctónico, nativo de Norte América, pero reportado en Europa, Asia y hasta el momento en Sudamérica en Brasil y Argentina, donde ha sido señalado como especie invasora. En muestreos de zooplancton realizados en la zona fótica de diferentes ecosistemas colombianos (humedales urbanos, embalses y ríos) entre el 2019 y el 2022 se registraron individuos K. bostoniensis. Este trabajo representa el primer reporte para Colombia y el norte de Sudamérica expandiendo su rango de distribución en el continente. Los especímenes analizados muestran las características morfológicas y morfométricas típicas de la especie K. bostoniensis y una distribución en un amplio rango de condiciones ambientales, como ha sido reportado en otras regiones. Se evidencia su potencial invasor y la posibilidad de que su rango de distribución se expanda hacia otras cuencas y ecosistemas colombianos, así como otros países de Sur América.

Peter Joseph Hocking Weeks, o Pedro Hocking como era conocido en Lima, nació en Pucallpa el 7 de julio de 1938 y falleció en Lima el 31 de octubre de 2022. Pedro Hocking no tuvo una formación científica, pero sí fue reconocido en vida como un naturalista por sus importantes contribuciones al conocimiento y documentación de las aves peruanas. Pedro Hocking fue parte de una generación apasionada por la biodiversidad, para la cual cada localidad visitada era un mundo nuevo que contenía especies desconocidas y que no disponía de las guías de campo ni de los recursos tecnológicos actuales para identificar in situ las que ya eran conocidas. Era una época en que la colecta de ejemplares era la herramienta básica para conocer la biodiversidad de una localidad y la actividad principal de las expediciones. Aunque su interés principal eran las aves, sus aportes no se limitaron a ellas sino incluyeron también otros grupos de fauna.

Published: November 2022

DAMSS-2022 is the 13th International Conference on Data Analysis Methods for Software Systems, held in Druskininkai, Lithuania. Every year at the same place and time. The exception was in 2020, when the world was gripped by the Covid-19 pandemic and the movement of people was severely restricted. After a year’s break, the conference is back on track. 2021 conference was successful, and the main objective of lively scientific communication was again achieved. The conference focuses on live interaction among participants, but there is also some scope for a limited number of virtual presentations. For better efficiency of communication among participants, most of the presentations are poster presentations. This format is really effective.

The history of the conference goes back to 2009, when 16 papers were delivered. It started as a workshop and has now grown into a well-known conference. The idea of such workshop was conceived at the Institute of Mathematics and Informatics, which is now the Institute of Data Science and Digital Technologies of Vilnius University. The Lithuanian Academy of Sciences and the Lithuanian Computer Society supported this idea. This idea has been welcomed by the Lithuanian scientific community and abroad. The number of this year’s presentations is 81. The number of registered participants is 121 from 10 countries. This is significantly more than in 2021. The conference brings together researchers from six Lithuanian universities. This makes the conference the main annual meeting point for Lithuanian computer scientists. The main goal of the conference is to introduce the research undertaken at Lithuanian and foreign universities in the fields of data science and software engineering. The annual organization of the conference allows the fast interchanging of new ideas among the scientific community. Seven IT companies supported the conference this year. This means that the topics of the conference are actual for business, too.

Published: November 2022

Introduction: Retinopathy of prematurity is a bilateral dysfunction of abnormal retinal vascularization in preterm infants, especially those with very low birth weight. The consequences range from normal vision to blindness. In recent years, the survival rate for the extreme group of patients with prematurity has increased from 8% to 35% in middle-income countries, as well as its early identification of retinal damage and institution of appropriate treatment to prevent blindness and provide children with better overall development. The natural evolution of the disease generates a high social and financial cost for the entire community, since in its more advanced stages it causes severe and irreversible damage to vision, also impairing the entire cognitive and psychomotor development of the affected child. Objective: The aim of the study was to document the awareness about Retinopathy of Prematurity among nurses working at neonatal intensive care unit of Nampula Central Hospital in Mozambique. Methods: A questionnaire was designed on awareness pattern. The questionnaire included questions about nurses education and experience, knowledge of screening guidelines, risk factors for Retinopathy of Prematurity, diagnose and treatment and it was applied to16 nurses working at neonatal intensive care unit of Nampula Central Hospital in Mozambique. It was a self-administered questionnaire, collected in October 2021. Results: The total number of the sample was 16 nurses, 87.5% were female and 12.5% were male. The mean age of study participants was 35.9 ± 7.3 years old. It was observed that the age of respondents shows predominance towards 40 years and above. Regarding the working experience at the neonatal intensive care, 43.75% of participants ranged from 1-4 years. Among the most cited risk factors; indicated professional to perform the eye exam; timing to perform the eye exam and the indicated treatment for Retinopathy of Prematurity, the following stand out: Low gestational age (56.25%);Retina Specialist(75.0%); Depends of Gestational Age (56.25%) and Cryotherapy alongside with Laser Photocoagulation and surgery (31.25%). Conclusion: The results of the study suggest that most nurses working in the neonatal Intensive care unit services of Nampula Central Hospital were aware about the prevention, diagnose and treatment of Retinopathy of Prematurity. The findings indicate the need for dissemination of information through seminars, workshops and internal educational activities to improve nurses' awareness about the clinical condition.
Neurodegenerative diseases oculomotor manifestations. clinical cases
Authors: Moyseyenko Nataliya
Published: November 2022

Oculomotor manifestations (nystagmus and diplopia) do not lead to blindness. But the loss of cognitive properties in the background, such as ability recognition and reading, leads to irreparable social consequences. Therefore, improved methods of diagnostic oculomotor disorders will help reveal neurodegenerative disease in earlier stages. Moreover, their correction will prevent undesirable outcomes. Clinical case 1- Partial Parinaue's syndrome, confirmed by MRI revealed multiple small degenerations in the area of the brain bridge (according to the localization indicated by Parinaue's syndrome - in the dorsal - medial part). Clinical case 2- Pronounced vertical-rotational nystagmus of both eyes with greater amplitude in the lead positions. Viral encephalomyelitis. In their form and nature, oculomotor disorders are a good indicator of the topic of damage to deep brain structures such as the trunk and bridge. Therefore, a more thorough study will help diagnose neurodegenerative injury in the early stages, treatment and prevent unwanted social consequences.

Published: November 2022

Purpose: To evaluate anxiety, depression status, and vision-related quality of life (QoL) in patients with age-related macular degeneration (AMD) during the early phase of the COVID-19 pandemic. Results: There was no statistically significant difference in HADS-A and HADS-D between the AMD group and controls (p<0.05) When the patients with AMD were assigned to two distinct groups according to binocular visual acuity, the proportion of patients above the HADS cut-off points for anxiety did not differ between the groups (p=0.208) and 55.6 % of patients above the HADS cut-off points of depression in low vision AMD group were significantly different from other groups (p=0,022). The statistically significant lower means of NEI-VFQ-25 parameters except for general health and ocular pain were observed in AMD patients compared with controls (p<0.05). Conclusions: Higher rates of depression were observed in subgroup of AMD having poor visual acuity. The AMD patients had lower vision-related QoL scores during the COVID-19 pandemic and it is recommended psychiatric counseling opportunities are needed for AMD patients having low binocular visual acuity.

Management of end stage sCJD from a palliative care perspective
Authors: Majeed Sheraz , Bartlam Karen , Yuan Tang Chee
Published: November 2022

Sporadic Creutzfeldt-Jakob Disease (sCJD) is a rare, rapidly progressive neurological disorder, that is ultimately fatal. We have written a case report on a patient recently admitted to the hospice having been diagnosed 2 days earlier with sCJD. Unfortunately, she had an aggressive form and deteriorated very rapidly 10 days post admission. Our focus was on symptom control and supportive care, for both patient and family, with psychological and spiritual support a vital component of this. Of her multitude of symptoms, the most challenging were the fluctuating episodes of severe emotional distress, agitation and restlessness. Non-pharmacological approaches proved extremely helpful, but as the disease progressed, we found that in addition to this, a combination of midazolam, levomepromazine and morphine proved the most effective in her syringe driver. All of this care took place within the context of a holistic, multi-disciplinary team, vital for managing the rapidly changing symptoms of this complex disease and its effect on both patient and family. Given its rare nature, there is only limited research on the palliative care aspects of managing terminal sCJD. We therefore hope that by sharing our experience, this case report may prove helpful.
Coffee prevents damaged of wound bed cells
Authors: Yuwono Hendro Sudjono , Nugroho Boby Eko
Published: November 2022

Objectives: The superficial wound cells adhered to the dressing during replacement and may delay wound healing. It is different from using the coffee ground as a wound dressing. The coffee has an impressive antioxidant, anti-inflammatory, and antibacterial power. Some of it stayed on the wound to protect the proliferating cells. Are there any wound cells shed when dressing change using coffee ground? Methods: We conducted a prospective observational study in Wistar rats as an experimental randomized control trial using 27 rats of 250 grams divided into three groups. The wound size was 2cmx2cm, deep 2 mm at the back skin, and closed using gauze-saline (Group-1), foam dressing (Group-2), and coffee powder (Group-3). On the 7th day, the dressing was fixed using Liqui-PREP solution to make histologic slides to counting the epithelial cells using a microscope with 200x magnification. The wound biopsied for histologic assessment. Scoring of attached cells in wound dressing: < 10/HPF= score 3, 10-20/HPF= score 2, >20/HPF = score 1. The healing of collagen tissue density 0 to 50% = score 1, 50-75% =score 2, 75-100%=score 3. The healing of epithelialization density 0 to 50% = score 1, 50-75%=score 2, 75-100%=score 3.

In Astyanax (Poecilurichthys), we recognize six species-groups defined by the distribution of melanophores on the body: 1. bimaculatus; 2. rupununi; 3. abramis: 4. orthodus; 5. asuncionensis; and 6. anterior, which are named for a representative species. Astyanax brevoortii1 is redescribed using specimens from Trinidad (including types). This species, as a member of the bimaculatus species-group, is distinguished by lacking a concentration of melanophores outlining the scale margins on the sides of body. Three new species of the bimaculatus species-group are described: A. caroni n. sp. from the Caroni River drainage, which differs in having all of the teeth of the internal premaxillary series pentacuspid (vs. heptacuspid), and the length of the caudal-peduncle spot which is less than two times the eye diameter (vs. at least twice eye diameter). A. garuttii n. sp. from the San Juan River and Gulf of Cariaco drainages is distinguished by osteological characters and by morphological characters identified by principal component analysis. A. cuyuni n. sp. from the Cuyuni River (Essequibo River Basin), is distinguished by having a foramen in the pterotic and sphenotic bones (vs. absent), and the shape of the last two neural spines that form a posteriorly directed arc, that covers the epineurals.

Susceptibility and vulnerability to impacts make Cetaceans and Benthic Foraminifera sentinels of health in marine environments. A breeding population of Right whales (Eubalaena australis) annually migrates to the “Environmental Protection Area” in Santa Catarina, Brazil, where Ribanceira/Ibiraquera Bay, and its harbor, are located. Since Right whales rest in shallow areas, their stomachs touch the marine sediment bottom, where foraminiferal assemblages inhabits. Temperature, salinity, pH, turbidity, grain size, morphometry, and magnetic susceptibility correlated to foraminiferal species, contribute to the understanding of habitat preference for right whales. Here we show saline waters in the northern areas associated with Pseudononion atlanticum, Elphidium sp., Buccella peruviana, Quinqueloculina patagonica, and 21°C of temperature is the preferred by mother and calf pairs. The harbor has lower pH, higher temperatures, magnetic susceptibility, and turbidity, and high depth is due to dredging. These characteristics do not support the presence of the Right whales, the top of the food pyramid, so decline or increase in their population indicates changes in their habitat. We stress the importance of unravelling signals of Benthic and Nekton coupling by understanding whales’ habitat; to ensure the recovery of their populations, and the survival of other species in the marine ecosystem.
Bone changes in condyles of asymptomatic temperomandibular joints & its correlation with age, gender and occlusal condition; a digital panoramic study
Authors: Kumar G  Arun
Published: November 2022

Introduction: The TMJ undergoes remodeling throughoutlifetime. Several studies on bone changes in patients with TMDs are conducted but limited literature exists on prevalence of bone changes in condyles of asymptomatic TMJs. Hence the present study was proposed to evaluate the prevalence of condylar bone changes among healthy adult Indian population with no complaints of TMDs & correlation with age, gender and dental condition. Methods: The present study was done on sample size of 250 patients consisting of 5 groups according to age: 20-29, 30-39, 40-49, 50-59 and 60-69 years, 50 patients each (25 males and 25 females). Digital OPG images were analyzed using Digora PCT software. Parameters were recorded and analyzed using chi-square test, paired, independent t-tests and 1-way anova analysis. Results: The angled shape was most frequent morphology among asymptomatic subjects in this study. The difference between age groups in relation to frequency of right condylar morphology was statistically significant (P<0.05). The prevalence of changes in condylar bone changes was more in individuals above 50yrs as compared to those below the age of 40 yrs. The radiographic bone changes are most commonly observed in older age groups. The condylar width and condylar height asymmetry index in different age groups was statistically significant (P<0.05).

Introduction: Temporomandibular joint ankylosis is fusion of the head of mandibular condyle to the glenoid fossa of temporal bone at skull base. Untreated ankylosis causes distressing conditions such as speech impairment, difficulty in chewing, poor oral hygiene, malocclusion, facial disfigurement, and compromise of the airway. The two main causes are trauma and infection in or around the joint regions. Methodology: A retrospective cross sectional study was conducted in 25 patients (n=14 male and n=11 female) with mean age of 21.9(ranged 6-50) diagnosed with Temporomandibular joint ankylosis at Addis Ababa University, Oral and Maxillofacial Surgery affiliate Hospitals both Yekatit 12 Hospital medical college and St. Peter specialized Hospital. Data was collected from patients’ medical records registered in a period of 3 years from January 2017 to December 2019. Epidemiological information (EPI- INFO 7) computer software was used for data analysis. Result: The study results revealed trauma was the most common cause of TMJ ankylosis representing (80%) of all causes. Males were more affected (56%) than females. The highest incidence of ankylosis was between the age of 11 and 20 (40%). Unilateral ankylosis was reported in (60%) and (68%) was bony ankylosis based on tissue involved. A total of (40%) of the patients were treated by interposition gap arthroplasty by using temporal muscle and fascia as an interposition material. Conclusion: The findings of this study conclude trauma was the commonest cause of ankylosis. A proper screening of childhood injuries and early referral to maxillofacial centers recommended ensuring proper evaluation of specific post traumatic aetiologic factors and for early treatment to prevent ankylosis.

Solar radiation is responsible for most cancers of the lower lip, if the diagnosis is late, the prognosis is unfavorable, the treatments are mutilating, palliative and expensive. This prevention campaign unprecedented in the country with a public-private partnership, aimed at informing and evaluating beach workers on the beaches of Santos, SP, Brazil, in relation to sun exposure and lip injuries. In three training workshops were held with the evaluators and instructions on the approach and calibration regarding questions and answers. A total of 119 beach workers who received information about care, symptoms and forms of sun prevention were evaluated, an explanatory folder was developed by the team and was distributed along with samples of sunscreen. Oral examination was performed evaluating lips and perioral mucosa through inspection and palpation maneuvers and within the needs of oral treatment they were referred for treatment. The results showed that only 7.56% use lip balm and 29.4% use body protector. In the lip evaluation, alterations were observed in 35 of the beach workers (29.41%) of the observed population, in 4 women (10%) and 31 men (39.24%). The data obtained may serve as a guide for preventive campaigns for this population at risk for the development of labial and perioral lesions. More attention is needed to this vulnerable population on the effects of sun exposure, protective care is not performed properly by most beach workers.

The study determined the spatial distribution and classification of private hospitals in the Northern Senatorial District of Taraba, Nigeria. A survey research design was adopted for the study. Interview, ground truth observation and handheld GPS device were the tools employed in data collection. Data analysis involved the descriptive statistics and geospatial mapping of the study area. The result shows that there are 40 private hospitals across the northern senatorial districts of Taraba state. These are distributed as follows; Karim-Lamido has seven (7), Ardo-Kola has three (3), Lau has three (3), Yorro has three (3), Zing has one (1), and Jalingo has twenty-three (23). The result shows that the nearest neighbour ratio is 0.816940 (observed mean distance divided by the expected mean distance), with a critical value of <-2.58 and a test of significance of P-value of 0.0071445. The result shows that the spatial pattern of distribution of private hospitals in the northern Taraba senatorial district is random, and there is less than 1% likelihood that this random pattern could be the result of random chance. The random pattern shows that the hospitals are not evenly distributed over space. This implies that the private hospitals in the northern senatorial district of Taraba State are randomly distributed. The result shows that there are 94 medical doctors and 176 nurses representing 27.9% and 52.2%, respectively, showing an average ratio of one doctor to two nurses per hospital (1:2). The result revealed that two (2) private hospitals are single-specialty tertiary care hospitals; Nobis Eye Clinic offering ophthalmological care services while Balsam Clinic offers osteology services. Three (3) general secondary care services (Jaji Memorial Hospital, UMCN Hospital & Catholic Hospital), while the remaining thirty-five offer primary care/nursing homes. The result also shows that there are three (3) specialty hospitals in the study area; this includes osteology (Balsam Clinic), ophthalmology (Nobis Eye Clinic) and a dental hospital (Family Dental Hospital). All these are located in Jalingo, the state capital. The others offer services in the category of general hospitals, though only a few (3) have the bed capacity to be classified as a general hospital. The study recommended that the distribution of private hospitals should be planned in such a way that they can reach more patients in terms of spatial coverage. It is further recommended that private hospitals should upgrade their facilities and bed capacity and employ more nurses and pharmacists to cater for the vast number of patients in the study area.
