Authors: RAKESH K. SHARMA  , U.K. SHRIVASTAVA
Published: December 2023

An on farm trial conducted during the rainy seasons of 1999 and 2000 on farmer s field of village Bhagwanpura under the operational area of Krishi Vigyan Kendra, showed that farmer s practice of following dora (a small bakhar shape implement, drawn by a pair of bullocks between the rows of a crop) 3 times 2 hand weedings at 15 and 30 days after sowing recorded the least weed population and weed dry weight and highest grain and straw yields compared to other treatments. Pre emergence application of Alachlor granules 20 kg/ha proved as effective as farmer s practice for grain and straw yields of soybean and gave the highest net profit (Rs 22,727/ha.) and benefit : cost ratio (1 55).
Productivity and nutrient-use efficiency of soybean (Glycine max) and sorghum (Sorghum bicolor) intercropping at different levels of nitrogen in rainfed deep vertisols
Authors: P. RAMESH  , K. SAMMI REDDY
Published: December 2023

A field experiment was conducted during the rainy season of 2000 and 2001 on deep Vertisols of Bhopal, to study the effect of soybean [Glycine max (L.) Merr.] and sorghum [Sorghum bicolor (L.) Moench] intercropping (2:l row ratio) in comparison to their sole crops at 3 levels of nitrogen (0, 75 and 100% recommended dose). Sole sorghum recorded higher seed, straw and soybean-equivalent yield (SEY) compared to either sole soy- bean or soybean + sorghum intercropping. However at No, soybean + sorghum intercropping resulted in higher SEY and at higher N status (75 or loo%), sole sorghum resulted in higher SEY. Nitrogen-uptake was higher in sole soybean, whereas P and K uptake were higher in sole sorghum. Sole sorghum recorded higher nutrient- use efficiency (NUE), whereas sole soybean resulted in lower NUE. However, nutrient harvest index of NPK -were higher in sole soybean and lowest in sole sorghum. Increased N levels significantly improved the SEY, nu- trient uptake and agronomic and recovery efficiency of NPK. However, physiological efficiency and nutrient har- vest index of NPK were not affected due to increased N levels.

Published: December 2023

An experiment with 3 dates of sowing and 4 castor (Ricinus communis L.) cultivars was conducted at Agricul- tural College Farm, Rajendranagar, Hyderabad, during summer seasons of 1995-96 and 1996-97 after the rainy- season rice (Oryza sativa L.). Growth parameters, yield attributes, seed and oil yields and harvest index of cnstor were higher when the crop was sown on 5 January followed by 20 December. Delayed sowing of castor on 20 January reduced the seed yield by 14 and 1 I%, respectively, compared to 5 January and 20 December sown crop. Among cultivars tested, hybrids recorded significantly higher growth, yield components, seed and oil yields than the varieties. The interaction between dates of sowing and cultivars was non-significant.

Published: December 2023

A field experiment was conducted during the winter and spring months of 2000 and 2001 at Hatay, Turkey (36O 36O 40' E), to study the effects of farmyard manure (0, 10, 20, 30, 40 and 50 tonnestha) and mineral fertiliza- 39. N, tion (no or 200-90-90 kgtha N-P-K respectively) on growth and yield of early potato (Solanum tuberosum L.) crop. Mineral fertilization significantly increased values of morphological traits and tuber yield, while it had negative ef- fect on dry matter content of tuber. The application of farmyard manure also had positive effects on growth and yield with or without mineral fertilization. The farmyard manure also increased the efficiency of mineral fertilization. Tuber yield increased as the farmyard manure levels increased under non-mineral fertilized conditions while no significant increase obtained from 40 and 50 tonnes manuretha rates in mineral-fertilized plots. Aplication of farm- yard manure significantly increased the dry-matter content of tuber and this was more evident in mineral fertilized plots.
Effect of organic and inorganic mulches on soil-moisture conservation, weed sup- pression and yield of elephant-foot yam (Amorphophallus paeoniifolius)
Authors: S.B. GOSWAMI  , S. SAHA
Published: December 2023

A field investigation on elephant-foot yam (Amorphophallus paeoniifolius Blume) was carried out during the pre-rainy and rainy seasons (kharif) of 2001 and 2002 with various mulch materials, viz. transparent polythene, black polythene, wheat straw, paddy straw, banana leaf, water hyacinth (Eichhornia crassipes) and cowpea (Vigna sp.) as cover crop. Black polythene, paddy straw and water hyacinth recorded significantly higher yields (50.2-52.8 tonneslha), which was 7.1-28.8% more than that of no-mulch control. Black polythene recorded the highest weed-control efficiency (92.1%). Mulches conserved the soil moisture by 26.3 to 29.7% in the soil (0-30 cm). Organic and inorganic mulches were on a par with each other in maintaining the soil-moisture status. Higher benefit : cost (B:C) ratio (3.12-3.38) was observed under application of organic mulch compared with that of inorganic or synthetic mulches (1.88-2.09).

Published: December 2023

A field experiment was conducted on well-drained sandy loam soils during the winter, summer and rainy (kharif) seasons of 2003-04 to study the nutritional requirement of major nutrients (P, K) for lucerne (Medicago sativa L.) crop. Application of 300 kg K,O/ha significantly increased the green-forage, dry-matter and crude-pro- tein yields by 17.2, 13.3 and 17.6%, respectively over the control (50 kg K,O/ha), whereas the application of 150 kg K,O/ha significantly increased the green-forage yield only compared with the control in cumulative yield of 12 cuts. Both the lucerne varieties ('GAUL I', 'AL 3') were more responsive to higher levels of potassium. Applica- tion of 75 kg P,O$ha along with 300 kg K,O/ha to lucerne variety 'AL 3' recorded significantly highest dry-matter yield and maximum uptake of N , P and K, whereas the highest crude-protein yield and the maximum uptake of N and K were obtained with combined application of 75 kg P205/ha and 300 kg K,O/ha to variety 'GAUL 1'. Applica- + tion of 50 kg P205 300 kg K20/ha to 'GAUL I' showed the maximum net return and net incremental cost: benefit ratio, followed by application of 75 kg P,O$ha + 300 kg K,O/ha to variety 'AL 3'.

Published: December 2023

A field experiment was conducted during the rainy seasons (kharif) of 2002 and 2003 at the Research Farm of the institute at Varanasi to study the effect of superimposition of fortified and unfortified rice-straw compost Q 6 tl ha over recommended NPK (120 kg N, 60 kg P,O, 60 kg K,O/ha) on growth, yield and nutrient uptake by rice (Oryza sativa L.). Among the different cellulo-azoto-bacterio compost treatments, rice-straw compost @ 6 tlha in- oculated with Azotobacter + phosphous solublizing bacteria (PSB) along with NPK registered significantly higher plant height, leaf-area index and yield attributes (panicles, panicle length, grainslpanicle and test weight), and gave 21.17% increase in grain and 15.36% in straw yields compared with NPK (120 kg N, 60 kg P,O, 60 kg K,O/ha). This treatment also gave the highest net returns (Rs 18,946lha). Application of rice-straw compost inocu- lated with cellulolytic fungi + Azotobacter + PSB along with NPK was also equally effective as rice-straw compost inocluated with Azotobacter + PSB (cellulo-azoto-bacterio compost) along with NPK in terms of leaf-area index, number of panicles, grainslpanicle, test weight and K uptake by rice. Fortified compost with Azotoacter and PSB + NPK also maintained soil fertility, as indicated by higher contents of organic carbon, available nitrogen, phos- phorus and potassium. However, values of these parameters showed declining trend with recommended level of NPK (control).

Published: December 2023

A field experiment was conducted during the winter (rabi) seasons of 201516 and 201617 at Kalyani (Nadia), West Bengal, India, to determine the effect of boron and zinc on growth and yield of potato (Solanum tuberosum L.) under lower Gangetic plains of West Bengal. The experiment was laid out in a randomized block design with 4 replications, having 7 treatments. Micronutrient-management practices could not significantly affected plant emer- gence of potato, and it was above 98.3%. Application of both zinc and boron improved the growth and yield of po- tato significantly. Zinc and boron acted synergistically in increasing the tuber yield. The highest total tuber yield (30.12 t/ha) of potato was recorded with foliar application of 0.1% boron + 0.1% zinc along with recommended dose of fertilizer (RDF) of NPK. Soil application of only boron, only zinc and boron + zinc increased the total yield of tubers by 12.7%, 3.23% and 22.41%, respectively, over RDF of NPK only. The foliar application of only boron, only zinc and boron + zinc increased the total yield of tubers by 18.71%, 7.70% and 29.55%, respectively, over RDF of NPK only. The effect of boron in increasing tuber yield of potato was found more pronounced than zinc in our study experimental situation. Foliar application of B and Zn was found superior in increasing tuber yield to their soil application. The highest uptake of N, P, K, B and Zn were recorded with foliar application of B and Zn over RDF. Soil application of B and Zn significantly increased the B and Zn concentration in soil. Foliar application of B and Zn over RDF of NPK resulted in the highest net returns.

Authors: Pangrazio Kullak Osvaldo Miguel , Forriol Campos Francisco Luis , Gossen Spatuzza Gabriela
Published: December 2023

Introducción: La Hormona Gonadotrofina Coriónica (HGC) es uno de los elementos a detectar en los controles antidopaje en el fútbol, pues está incluida en la Lista de Prohibiciones 2023 de la Agencia Mundial Antidopaje (AMA-WADA), en el grupo S2 Hormonas peptídicas, factores de crecimiento, sustancias afines y miméticos. Las cantidades elevadas de hCG pueden ser un diagnóstico de cáncer testicular. El objetivo del estudio es determinar la frecuencia de detección de cantidades elevadas de HGC en jugadores de sexo masculino en las competiciones de fútbol CONMEBOL para comunicárselo al jugador y establecer el diagnóstico con estudios especializados.
Material y metodología: Estudio prospectivo observacional de casos, entre enero de 2014 a marzo de 2023, cuando se realizaron 18.110 controles antidopaje de orina y sangre en todos los partidos oficiales CONMEBOL de fútbol: campo, futsal y playa, siguiendo el protocolo CONMEBOL. La orina era analizada en laboratorios acreditados según lo establecido por el WADA Technical Document – TD2021CG/LH. Se analizaron los valores de HGC en todos los controles de antidopaje realizados para determinar aquellos con cantidades elevadas de HGC en orina.
Resultados: Se encontraron muestras elevadas en dos casos (0,01%) y se procedió de acuerdo a los establecido en el procedimiento de la gestión de resultados para este tipo de casos; se notificó al jugador y se solicitaron estudios médicos especializados para corroborar o descartar un posible caso de tumor testicular. En ambos casos, se confirmó un seminoma testicular con aumento de la ß-hCG. Las ecografías testiculares y los marcadores tumorales en la analítica sanguínea confirmaron los diagnósticos. Los tratamientos definitivos se realizaron 10 días después de la primera visita, efectuando una orquiectomía.
Conclusión: La determinación de hCG en cantidades elevadas en los controles antidopaje en el fútbol masculino, además de determinar una sustancia prohibida, pueden detectar de forma temprana tumores testiculares

Published: December 2023

Objective: The ideal type of hospital to care for adult congenital heart disease (ACHD) patients is not well known. Hospital competitiveness, clinical volume and market structure can influence clinical outcomes. We sought to understand how hospital competitiveness affects clinical outcomes in ACHD patients in the era prior to the Adult Congenital Heart Association accreditation program. Methods: Patient discharges with ACHD diagnosis codes were filtered between 2006–2011 from an all-payer inpatient healthcare database. Hospital-level data was linked to market structure patient flow. A common measure of market concentration used to determine market competitiveness—the Herfindahl-Hirschman Index (HHI)—was stratified into: more competitive (HHI ≤25th percentile), moderately competitive (HHI 25th to <75th percentile), and less competitive (HHI ≥75th percentile) hospital. Any complication, home discharge and mortality were analyzed with clustered mixed effects logistic regression. The combined impact of HHI and any complication on mortality by interaction was assessed. Results: A total of 67,434 patient discharges were isolated. More competitive hospitals discharged the least number of patients (N = 15,270, 22.6%) versus moderately competitive (N = 36,244, 53.7%) and less competitive (N = 15,920, 23.6%) hospitals. The adjusted odds of any complication or home discharge were not associated with hospital competitiveness strata. Compared to more competitive hospitals, mortality at moderately competitive hospitals (Adjusted Odds Ratio (AOR) 0.79, 95% CI: 0.66–0.94) and less competitive hospitals (AOR 0.79, 95% CI: 0.63–0.98) were lower (p = 0.025). Age, race, elective admission, transfer status, and payer mix were all significantly associated with adjusted odds of any complication, home discharge and mortality (p ≤ 0.05). Having any complication independently increased the adjusted odds of mortality more than 6-fold (p < 0.001), and this trend was independent of HHI strata. Failure to rescue an ACHD patient from mortality after having any complication is highest at less competitive hospitals. Sensitivity analysis which excluded the transfer status variable, showed that any complication (p = 0.047) and mortality (p = 0.01) were independently associated with HHI strata. Conclusions: Whether lower competition allow hospitals to focus more on quality of care is unknown. Hospital competitiveness and outcome seem to have an inverse trend relationship among ACHD patients. Since medical care is frequently provided away from the home area, hospital selection is an important issue for ACHD patients. Further research is needed to determine why competitiveness is linked to surgical outcomes in this population.

Published: December 2023

Objective: This study aimed to explore and analyze the factors affecting the incidence of pneumonia after coronary artery bypass grafting (CABG) to provide reference for the prevention of such situation. Methods: A total of 500 patients who underwent CABG in a hospital were selected. From March 2019 to March 2022, 410 patients without pneumonia and 90 patients with pneumonia were divided into groups A and B. The influencing factors and pathogen composition of postoperative pneumonia were discussed and analyzed. Results: Univariable analysis results showed that age, cardiac function grade, occurrence of smoking, operation time, tracheal intubation time, suspended red-blood-cell transfusion and hospital stay in group B were higher than those in group A. Multivariable logistic analysis results showed that operation time, smoking history, and tracheal intubation time were risk factors for pneumonia after CABG. Among the 90 patients with postoperative pneumonia, 90 had pathogens, 81 had Gram-negative bacteria, 4 had Gram-positive bacteria, and 5 had fungi. Conclusions: Patients after CABG were more likely to develop pneumonia. Operation time, smoking history, and tracheal intubation time were the risk factors of pneumonia after CABG. Most of these patients had Gram-negative bacteria. Patient intervention based on the influencing factors can effectively prevent the occurrence of postoperative pneumonia.

The aim of the study was studying the mechanisms of the relationship between neuroplasticity and cerebral visual impairment at the recovery stages of intracranial hemodynamic and liquor dynamic disturbances in children with NE. Materials and methods. Over the past 10 years, out of 3,500 children aged from 3 months to 6 years examined by us, with the help and cooperation of the children's neurological hospital, the Republican Perinatal Center and the Research Institute of Pediatrics, 1,500 children were diagnosed with acute cerebrovascular accident in the neonatal period of life. Homeostasis indicators-catecholamines in the blood, excretion in the urine, the sugar and cortisol in the blood, electrolytes in plasma and erythrocytes. NSG, MRI, CDU. The reactivity of BP, of the pulse and respiration to vegetotropic drugs and PA.EEG (sleep rhythm, emotional and motor activity) Results. It has been proven that the decisive mechanisms of recovery options depend on the orientation of the hypothalamic-pituitary relationship and the nature of homeostatic aberrations. The overwhelming majority of these children have experienced catecholamine excite dumping syndrome over these long years and had a clinical picture of both cerebral pathology and CVI. By compiling histograms, it was possible to establish that the effect of cholinergic mechanisms on general hemodynamics was less pronounced than on intraorbital blood circulation. In other words, the assessment of hemodynamic responsiveness to the stimulus revealed a more significant fluctuation in the index of intracranial rather than general hemodynamics. Conclusion. Analysis of variance proves that the stability of the mean dynamic blood pressure is one of the leading mechanisms for stabilization of adaptive homeostatic neuroplasticity of the CNS and visual analyzer.

Os zorápteros não têm nome popular no Brasil. Estão restritos às regiões tropicais e subtropicais do mundo (Mashimo et al. 2014) com exceção da Austrália. É a terceira menor ordem do mundo, com 44 espécies descritas (Matsumura et al. 2020), somente Grylloblattodea e Mantophasmatodea possuem menor número de espécies, mas nenhuma ocorre na região Neotropical. Nesta região, é a menor ordem de insetos, com 17 espécies descritas (Rafael et al. 2008). No Brasil, são conhecidas seis espécies (Rafael et al. 2008; Rafael & Lima 2022). A Reserva Ducke, em Manaus, é o local no país com maior número de espécies registradas, quatro (Rafael & Engel 2006; Rafael 2009). No mundo, estimam-se aproximadamente 100 espécies e, no Brasil, esse número deve atingir aproximadamente 30 espécies. Os zorápteros possuem corpo mole e são muito semelhantes a alguns psocópteros, diferenciando-se pela antena moniliforme com nove artículos nos adultos (filiforme em psocópteros) e cerco com um artículo (ausente em psocópteros).

Objective: The purpose of this study was to compare and evaluate the effectiveness of child-based cognitive-behavioral therapy (CCBT), family-based cognitive-behavioral therapy (FCBT) and mother-child attachment intervention in reducing separation anxiety in children aged 7 to 12 years. Methods and Materials: The method of this semi-experimental study was pre-test-post-test with a control group and a three-month follow-up. For this purpose, 48 children with separation anxiety disorder were selected by purposive sampling and were divided into four groups of 12 people. The first group received child-based cognitive behavioral therapy, the second group received family-based cognitive behavioral therapy, the third group received mother-child attachment intervention, and the control group did not receive any intervention. The measurement tools of this research include the semi-structured diagnostic interview of mood disorders and schizophrenia for children and adolescents (K-SADS-PL) and Separation Anxiety Scale (Parental Form). The data were analyzed using mixed variance analysis with repeated measurement and Bonferroni's post hoc test. Findings: The findings show that child-centered cognitive-behavioral therapy has been more successful in reducing separation anxiety compared to family-centered cognitive-behavioral therapy and mother-child attachment-centered intervention. Also, family-centered cognitive-behavioral therapy has been more effective in reducing children's separation anxiety compared to mother-child attachment-centered intervention (P<0.05). Conclusion: The results of the present study show that the therapeutic methods used can be effective in the treatment of separation anxiety disorder by psychologists and psychiatrists.
TECNOLOGIA, O ACESSO À JUSTIÇA NO PODER JUDICIÁRIO DE RONDÔNIA E O COVID-19
Authors: Mazzini Cristiano Gomes
Published: December 2023

A tecnologia, inserida no Poder Judiciário desde o sistema operacional em disco (Disk Operating System – DOS) até o processo eletrônico, já havia se mostrado poderosa quando aliada à atuação estatal para a ampliação do acesso à justiça, sobretudo diante do crescente acervo processual. Contudo, a partir da declaração de pandemia pela Organização Mundial de Saúde (OMS), em março de 2020, em razão da disseminação do novo coronavírus (Sars-Cov-2), a tecnologia assumiu o protagonismo na realização dos atos processuais, especialmente com a utilização do Processo Judicial Eletrônico, além do uso de sistemas de videoconferência que facilitam a realização de audiências, reuniões, sessões de julgamento, o que demonstra que a tecnologia,, portanto, é a grande responsável pela manutenção e funcionamento dos Tribunais de Justiça do Brasil. Sob essa perspectiva, o objetivo da presente pesquisa é de analisar como o uso da tecnologia e de suas ferramentas funciona como ampliadora do acesso à justiça e, de forma reflexa, um mecanismo de justiça social.
AMAZÔNIA

Published: December 2023

Em vários momentos da história do Brasil, a Amazônia sempre assumiu o destaque de protagonismo quando se pensou em fronteiras. Inicialmente, usada pela Metrópole portuguesa, serviu como proteção territorial da colônia; posteriormente foi o instrumento de demarcação da soberania enquanto projeto de governo e, hoje é o ponto central da expansão territorial para o agronegócio. No contexto, contudo, segue sem tratamento a massiva degradação ambiental. Assim, este trabalho procura discutir o cenário global em que repousa a maior floresta tropical do mundo e as alternativas que podem aplacar o processo de desmatamento, ao mesmo tempo em que não se descarta melhor uso da área que já existe para ser explorada, tudo isso a partir de um método analítico bibliográfico. Ao final do texto, consolidamos a apreensão científica que coloca a floresta como um bem de grande importância para o equilíbrio climático mundial.

Os empreendimentos hidrelétricos são grandes protagonistas no incremento econômico-energético brasileiro. Ocorre que, para a implantação adequada de uma matriz energética hidrelétrica em determinado local, é preciso uma correta mensuração e alocação de riscos, especialmente em relação às populações impactadas. Existem diversas recomendações de organismos internacionais, a fim evitar e/ou mitigar os danos às vítimas dessas obras de infraestrutura. Não raro os estudos prévios de grandes empreendimentos hidrelétricos costumam subdimensionar as áreas de impacto e descaracterizar a figura do atingido. Para verificar se esse é o caso dos estudos prévios para a construção da UHE Tabajara, no Rio Machado, é que o artigo se apresenta. A metodologia utilizada para o desenvolvimento do estudo se utilizará de revisão bibliográfica relacionada ao objeto de estudo, bem como de pesquisa documental, com base em análise do processo de licenciamento da UHE Tabajara e laudos periciais do Ministério Público Federal. Por fim, infere-se: a) a imprescindibilidade da inclusão das áreas dos distritos de Calama e Demarcação nos estudos de impacto do projeto; b) a revisão do cadastro socioeconômico da população potencialmente atingida e c) que se faz necessária a efetivação do direito da comunidade em participar do processo.

Os habitats de populações humanas e animais selvagens se sobrepõem, criando oportunidades para interações inevitáveis. O sauim-de-coleira (Saguinus bicolor), primata endêmico da região de Manaus, tem como principais ameaças a destruição e fragmentação da floresta. Com o avanço desordenado da cidade restaram fragmentos florestais onde sauins instigados pela disputa por espaço e recurso alimentar podem estar interagindo com humanos. Visando fornecer subsídios para a coexistência equilibrada entre ambos, este estudo investigou o comportamento interativo de moradores em relação à presença do sauim-de-coleira. Foram aplicadas entrevistas semi-estruturadas a 84 moradores, de sete fragmentos florestais. Os resultados mostram que as interações são: cooperação, afetividade, neutralidade, amansamento e competição. Essas interações funcionam como um indicativo do que deve ser trabalhado em áreas de simpatria entre humanos e sauins em termos de implementação e acompanhamento de projetos de educação ambiental.
Investigation of the Fracture Strength Between Dental Implant And Ti-Base Abutment Produced with Different Heights and Grades of Titanium Material
Authors: BANAZLI Hüseyin Anıl , GORLER Oguzhan
Published: December 2023

New prosthetic designs were developed to provide a balanced transmission of the stress caused by the chewing function to other mechanical and anatomical structures, and these designs revealed new research areas. An example of this is screw-retained implant-supported prostheses. With screw-retained prostheses, the residual cement problem is eliminated. However, abutment material and abutment design may adversely affect the mechanical and aesthetic properties of prostheses. Ti-base abutments have been developed to solve these problems. However, studies on clinical succes, material content and abutment height of ti-base abutments remain up-to-date. In our study, the effect or abutment heights on the bond strength and stress distribution with monolithic zirconia crowns in ti-base abutments manufactured from different titanium Gr types will be tested. Titanium Gr 4, Gr 5 and Gr 23 ELI materials will be used in our study. A total of 7 groups are planned with ti-base abutments with a abutment length of 3.5 mm, 5.5 mm for Gr 4 and Gr 5, abutment length of 3.5 mm, 5.5 mm and 7 mm for Gr 23. In the in vitro experiment, the fracture strength of the samples will be tested with the universal testing device. total of 77 implants, ti-base abutments and monolithic zirconia crowns will be used by creating 11 samples for each study group. The obtained values will be recorded in Newtons and Megapascals. The data will be analysed using the SPSS 22.0 programme. As a result, while the lowest fracture strength values were observed in Gr 4 Ti material in all ti-base abutment lengths in the samples for which the fracture strength test was performed, similar values were observed in the ti-base abutments produced from Gr 5 and Gr 23 ELİ alloys. When the relationship of bonding strengths with Ti alloys was evaluated, it was seen that there was no significant difference between Ti alloys.
Variation of coal quantity accumulated in the Mississippian to Pennsylvanian coal seams (Upper Silesia and Lublin Coal basins, Poland): a reflection of changes in climate and CO2 availability
Authors: Nieć Marek , Sermet Edyta , Salamon Ewa
Published: December 2023

Many coal seams of varied thickness and aerial extent occur in the Upper Silesia and Lublin basins within Mississippian and Pennsylvanian coal-bearing deposits. Well-documented data on coal quantity in the seams identified allows visualization of their variation within the stratigraphic succession and analysis of the time-dependent coal accumulation process. Some characteristic features of this variation were observed. Coal seams of the Mississippian age (Serpukhovian, Paralic Series), formed within a near-shore environment, most often constitute small resources. There were only two intervals of increased coal accumulation in seams of >100 million tons, in the lower and uppermost parts of the Paralic Series. Within the Pennsylvanian coal-bearing succession of terrestrial fluvio-lacustrine origin, a specific, wave-like pattern of seam resource variations and four intervals of increased coal accumulation are observed. In the Lublin Coal Basin, the Lublin Beds only, deposited during the Late Bashkirian, are coal-bearing, in which a bell-shaped pattern of seam resource variation in the stratigraphic succession is observed. The location of enhanced coal accumulation events in the stratigraphic succession suggests their repetition at ~1–4 My intervals. The characteristic features of the quantitative variation in these coal seams may be correlated with glacial-interglacial and climate humidity changes, and interpreted as a response to variable volcanogenic CO2 supply.

Dissecting posterior inferior cerebellar artery (PICA) aneurysms are uncommon lesions. Their anatomy and the location of the dissection are variable, however, they usually occurs at the origin of the PICA. Dissecting PICA aneurysms generally have non-vascular morphology involving an entire segment of the artery and cannot be cut. Nevertheless, the detection of these vascular lesions has increased latterly, so it is necessary to recognize it and take the appropriate management modalities for these injuries. In this report, we describe a case of a 73-year-old male patient, who presented a history of severe headache, associated with neck stiffness, nausea, vomiting, dizziness, hypoactivity, mental confusion, and walking difficulty. Radiographic investigation with brain computed tomography (CT) showed mild bleeding in a pre-medullary and pre-pontine cistern, and cerebral angiogram showed a dissecting PICA aneurysm. Despite being a challenging treatment, microsurgery management was the chosen modality. It was performed an end-to-end anastomosis between the p2/p3 segments, showing to be effective with good clinical and radiographic outcomes. We discussed an unusual case, reviewing the current literature on clinical presentations, the angiographic characteristics of the dissecting aneurysms of PICA, and evaluating the clinical and angiographic results of patients undergoing microsurgical treatment.
Inversions Can Accumulate Balanced Sexual Antagonism: Evidence from Simulations and Drosophila Experiments
Authors: McAllester Christopher S , Pool John E
Published: December 2023

Chromosomal inversion polymorphisms can be common, but the causes of their persistence are often unclear. We propose a model for the maintenance of inversion polymorphism, which requires that some variants contribute antagonistically to two phenotypes, one of which has negative frequency-dependent fitness. These conditions yield a form of frequency-dependent disruptive selection, favoring two predominant haplotypes segregating alleles that favor opposing antagonistic phenotypes. An inversion associated with one haplotype can reduce the fitness load incurred by generating recombinant offspring, reinforcing its linkage to the haplotype and enabling both haplotypes to accumulate more antagonistic variants than expected otherwise. We develop and apply a forward simulator to examine these dynamics under a tradeoff between survival and male display. These simulations indeed generate inversion-associated haplotypes with opposing sex-specific fitness effects. Antagonism strengthens with time, and can ultimately yield karyotypes at surprisingly predictable frequencies, with striking genotype frequency differences between sexes and between developmental stages. To test whether this model may contribute to well-studied yet enigmatic inversion polymorphisms in
Drosophila melanogaster
, we track inversion frequencies in laboratory crosses to test whether they influence male reproductive success or survival. We find that two of the four tested inversions show significant evidence for the tradeoff examined, with
In(3R)K
favoring survival and
In(3L)Ok
favoring male reproduction. In line with the apparent sex-specific fitness effects implied for both of those inversions,
In(3L)Ok
was also found to be less costly to the viability and/or longevity of males than females, whereas
In(3R)K
was more beneficial to female survival. Based on this work, we expect that balancing selection on antagonistically pleiotropic traits may provide a significant and underappreciated contribution to the maintenance of natural inversion polymorphism.
