A Base Nacional Comum Curricular, seus impactos sobre o ensino das Ciências Humanas e o contexto de sua produção
Authors: Chiaretti Alessandra Tatiane Galvão , Cintra Shirley Cristiane , Derisso Jose Luis
Published: November 2024

Este artigo analisa a implementação da Base Nacional Comum Curricular e avalia os pontos educacionais em Ciências Humanas – renomeada na Base para Ciências Humanas Sociais Aplicadas – por meio de um estudo documental, alicerçado na pedagogia histórico-crítica e no materialismo histórico-dialético. As reflexões indicam que movimentos ultraconservadores, movidos por entidades privadas, priorizam a formação para o mercado de trabalho em oposição às Ciências Humanas e Sociais. Esse viés se adequa à Pedagogia das Competências, que esvazia os currículos escolares, centra-se na geração de mão de obra e atende ao capital. Adicionalmente, discute-se a influência do contexto no qual a BNCC foi produzida, no sentido de torná-la menos crítica e mais alinhada aos interesses empresariais na educação.

An evaluation and comparison of frictional resistance, surface roughness, and microbial colonization of silver-coated and uncoated stainless steel archwires – An in vivo study
Authors: Raval Rutvi Vikram , Sharma Padmaja , Naik Harshit , Patel Kalpesh
Published: November 2024

Objectives:

When undergoing fixed orthodontic treatment, white spot lesions and caries are frequently observed. The silver coating on brackets, archwires, and bands can help prevent these conditions. However, this might have an impact on friction and the oral environment, which would then impact the movement of the teeth. Thus, this study was taken up to evaluate and compare the frictional resistance, surface roughness, and microbial colonization of silver-coated and uncoated stainless steel archwire.

Material and Methods:

The investigation contained sixty samples, with 30 samples in each sub-group. Group 1 included 30 samples of 0.019 × 0.025” stainless steel wires coated in silver nanoparticles and Group 2 included 30 uncoated 0.019 × 0.025” stainless steel wires. A thermal vacuum evaporation technique was used to coat the wire with a 10 nm layer of coating. After placing the wire for 6 weeks in the oral cavity, it was retrieved and evaluated for frictional resistance, surface roughness, and microbial colonization.

Results:

After comparing the friction across the groups, the results did not show statistically significant differences. Scanning electron microscopy revealed that the surface roughness of wires coated in silver was lesser compared to the wire’s uncoated segment. As for the microbial colonization, Streptococcus mutans and Lactobacillus acidophilus showed reduced growth in the silver-coated portion.

Conclusion:

It can be concluded that silver coating does not alter the frictional properties of the wire. In the archwire’s silver-coated part, the surface roughness was lower. The silver coating showed significant anti-bacterial activity.
An unusual late complication of peridural anesthesia: The case of a subdural spinal epidermoid cyst: A case report and literature review
Authors: Abdoulaye DIOP , Jihane LIMI , Natacha SAMBOU , Mortada JIHED , Srour ROBIN
Published: November 2024

The peridural approach is primarily used today to provide analgesia in obstetrics and postoperative care. Peridural analgesia is not only more effective than systemic analgesia, but it also has benefits in terms of morbidity, particularly regarding postoperative respiratory complications and the shortened duration of postoperative ileus. Unlike dural tears, immediate and severe neurological complications such as hematomas or abscesses are very rare. Long-term sequelae are less well known because the relationship with epidural analgesia performed several months or years earlier is not always well established. We report a rare case of a 35-year-old patient with a history of epidural anesthesia five years ago during childbirth, who was admitted with cauda equina syndrome. MRI (magnetic resonance imaging) of the lumbar spine showed a subdural lesion at the level of L3. The patient underwent resection of the lesion, and the pathological examination of the surgical specimen concluded it was an epidermoid cyst.

Authors:   Grodno Regional Clinical Cardiology Center, Grodno, Belarus, Krotkov K. O.
Published: November 2024

Background. To evaluate changes in acid-base balance in patients with coronary heart disease in the intraoperative period during coronary artery bypass grafting under artificial circulation using extracorporeal autohemomagnetotherapy (EAHMT). To consider the presence of a negative effect of this technique on acid-base balance. To study the possible relationship between the polymorphism of the angiotensin-1 receptor gene (AGTR1 A1166C), endothelin-1 (EDN1 Lys 198 Asn), endothelial nitric oxide synthase (NOS3 C786T) and changes in the studied parameters of acid-base balance. Material and methods. Group 1 included standard anesthesia for coronary artery bypass grafting under cardiopulmonary bypass without the use of EAHMT (60 patients). Group 2 included standard anesthesia for coronary artery bypass grafting under cardiopulmonary bypass with the use of EAHMT (63 patients). The following parameters of the acid-base balance of arterial blood were assessed: hydrogen index (pH), lactate (Lac), base deficit (SBE), potassium (K), sodium (Na), hemoglobin (Hb), hematocrit (Hct). All patients of both groups underwent intraoperative venous blood sampling from the central venous catheter. Then, the polymerase chain reaction method was used to study the genotypes of the angiotensin-1 receptor gene polymorphism (AGTR1 A1166C), endothelin-1 (EDN1 Lys 198 Asn), endothelial nitric oxide synthase (NOS3 C786T). Results. At the second stage of the study, a decrease in the hydrogen index of arterial blood, hemoglobin, hematocrit, and base deficit was revealed in both groups. A statistically significant increase in lactate and potassium was obtained in both study groups. No associations were found between the polymorphism of the angiotensin-1 receptor gene (AGTR1 A1166C), endothelin-1 (EDN1 Lys 198 Asn), endothelial nitric oxide synthase (NOS3 C786T) and the arterial blood acid-base balance. Conclusion. The use of EAHMT does not have negative impact on the electrolyte balance and acid-base composition of the blood. The presence of polymorphism of the AGTR1 gene A1166C (rs 5186), EDN1 gene Lys 198 Asn (rs5370), NOS3 gene C786T (rs 2070744) does not affect the acid-base balance of arterial blood.

Authors: И.А. Мальцева , Е.И. Мальцев , А.В. Яковийчук , А.С. Федорко
Published: November 2024

В статье представлены результаты исследований уровня накопления углерода искусственными сосновыми и дубовыми насаждениями в степной зоне (Старо-Бердянский лес, Запорожская область). Запасы углерода в дубовых насаждениях были в 1,8 раза выше, чем в сосновых. Наибольшее количество углерода накапливалось в биомассе стволов. Дуб черешчатый аккумулировал почти в 1,6 раз больше углерода, чем сосна крымская. В почвах насаждений с учетом лесной подстилки запасы углерода изменялись в диапазоне от 36,21 т С/га в сосновом насаждении до 85,7 т С/га - в дубовом. Отмечена активная роль почвенных микроводорослей и цианобактерий в формировании углеродного баланса насаждений. Они обеспечивали поглощение 97,22 кг/га углерода в месяц в дубовом и 83,68 кг/га - в сосновом насаждении. С учетом высокой скорости обновления биомассы микроводорослей и цианобактерий, количество связываемого ими углерода может достигать значений, сопоставимых с запасами углерода в лесных подстилках.

Authors: Е.К. Жаркова , В.М. Казакова , А.О. Ружицкий
Published: November 2024

Тимол является одним из важнейших химических компонентов тимьяна обыкновенного (Thymus vulgaris L.) за счет своей высокой биологической активности. Биосинтез тимола координируется каскадом ферментативных реакций, изучение которых важно для повышения продуктивности этого ценного лекарственного растения. Механизм реакции начинается с образования у-терпинена из геранилдифосфата при участии фермента терпиненсинтазы (TPS). Затем у-терпинен фосфорилируется под воздействием фермента семейства CYP, а затем промежуточные продукты катализируются дегидрогеназой, в дальнейшем преобразуясь в тимол. Изучение ферментов, ответственных за биосинтез тимола, является важной и актуальной задачей. Новизна исследования обусловлена выявлением метаболических процессов тимьяна обыкновенного, интрудуцированного в зону дерново-подзолистых почв.

Isolated Unilateral Optic Nerve Involvement as the Presenting Feature of Early Relapse in Philadelphia Chromosome Positive Acute Lymphoblastic Leukemia
Authors:   University of Toronto, Princess Margaret Cancer Center, Ontario, Canada, Alharbi Salman
Published: November 2024

Central Mervous System involvement (CNS) in Acute Lymphoblastic Leukemia (ALL) can be present at initial diagnosis or at disease relapse and early detection is crucial for prompt intervention. Optic nerve infiltration by leukemic cells is an oncologic emergency that requires urgent therapy to spare vision along with systemic therapy, with limited data about the optimal therapeutic strategy. Isolated optic nerve Involvement at relapse is rare; described in Philadelphia chromosome negative (Ph-) ALL in 2.2% of relapses in children and exceeding rare in Philadelphia chromosome positive (Ph+) cases, particularly in the absence of systemic disease.

Background: The odontoid process is an anchoring pivot for the craniovertebral junction and has many congenital anomalies. Ossiculum Terminale Persistans (OTP) and Os Odontoideum (OO) are believed to be rare developmental anomalies of the odontoid process. The OTP is defined as an ossification center that gives rise to the tip of the dens failing to fuse properly with the body of the axis. OO is described as an oval-shaped, well-corticated bony ossicle that is positioned cephalad to the body of the axis. Both of these conditions may cause neurological signs and atlantoaxial instability.

Agenesis of the gallbladder is a rare congenital anomaly. The aim of this study is to explore, through the case we present, the epidemiological aspects of this anomaly as well as the specificities of diagnosis and therapeutic management. The patient is a 35-year-old individual with no significant medical history, who presented with hepatic colic and an ultrasound showing a sclerotic and atrophic gallbladder. A laparoscopic cholecystectomy was indicated. Intraoperatively, the gallbladder was not visualized, even after examining various ectopic sites for the gallbladder.

The supravesical hernia is a rare cause of internal hernia, characterized by the protrusion of the intestine through an abnormal intra-abdominal opening located in the supravesical compartment. This anomaly is infrequently reported in the literature, and its incidence remains uncertain [1]. Supravesical hernias predominantly affect men over the age of 50 [2]. From a pathophysiological perspective, supravesical hernias develop from the supravesical fossae. They form medial to the umbilical arteries and often expand into the Retzius space, though they can also engage laterally, resulting in laterovesical hernias. These hernias are almost always acquired and can sometimes be associated with inguinal hernias. Clinically, they present as acute bowel obstruction. An abdominal CT scan can confirm the diagnosis of obstruction but rarely provides an etiological diagnosis [3]. In such cases, a median laparotomy is necessary, and intraoperative diagnosis is typically straightforward. Treatment involves sectioning the hernial neck and reducing the hernia, followed by simple closure of the opening using separate sutures with absorbable thread [4]. We report a case of a 56-year-old patient with no notable medical history was admitted to the emergency department with an internal supravesical hernia revealed by obstructive syndrome.

Sri Lanka faced a massive Foot and Mouth Disease (FMD) outbreak in 2014, which was initiated in Jaffna district in December 2013, and lasted for a period of more than a year, until January 2015. The disease spread throughout the country, affecting 68895 domestic animals, and causing 2007 deaths. The aim of this study was to epidemiologically analyze the data of 2014 FMD outbreak in order to understand the pattern and determinants of the massive disease distribution. Data were collected regarding the number of cases and deaths in relation to the time and location. Data in Disease Outbreak Reports, Follow-up Reports, Disease Investigation Reports and Laboratory Investigation Reports were reviewed, and descriptive and simple statistical analyses were carried out concerning the 57 epidemiological week study period. Disease Incidence, Period Prevalence, Mortality Rate, and Case Fatality Ratio of the disease were determined to be 68895, 6.11%, 0.18% and 2.91%, respectively. Seasonal animal movements and unauthorized livestock transportation appeared to be the main causes for the extensive spreading of the disease, while inadequate vaccination and poor awareness seemingly facilitated the development of three epidemic curves during the outbreak period. Newly identified causative agent, the sub-lineage O/ME-SA/Ind-2001d has led to a more severe FMD outbreak in 2014 compared to the previous outbreaks occurred in Sri Lanka.

Mineral nucleation is a fundamental process of paramount importance to various fields, including geology, biomineralization, and industrial manufacturing. Recently, studies on the biominerals of calcium carbonate and phosphate have revealed the presence of a dense liquid phase prior to the formation of an amorphous solid phase. However, there is vigorous debate on whether the nucleation of calcium carbonate clusters can be adequately described by the classical nucleation theory (CNT) or if one must turn to the non-classical nucleation theory. Here, we show that liquid-liquid phase separation (LLPS) occurs in a non-aqueous solution where magnesium and calcium carbonates are dissolved in ethanol with excess triethylamine. The nanodroplets can be kinetically trapped by triethylamine. The size and number of the nanodroplets, in the vicinity of critical nuclei, can be adequately described within the framework of CNT. We found that bicarbonate-like species formed by triethylamine, CO2, and ethanol molecules are in constant exchange with sizable carbonate clusters. Our results demonstrate that the concepts of critical nuclei and the energy barrier of nucleation are indeed physically relevant. We argue that nanodroplets comprising highly solvated carbonate clusters are the key entities in the nucleation process, which falls within the realm of CNT.
Computing Ligand Binding Free Energy in a Large Flexible Pocket of a Large Protein

Published: November 2024

Protein-ligand standard binding free energy (SBFE) calculations based on molecular dynamics simulations have recently emerged as an efficient tool for computer-aided drug design. However, the majority of studies have focused on well-defined ligand binding pockets in small proteins, while computing SBFE of a small molecule ligand to a large, flexible binding site remains problematic. Numerous proteins with large flexible binding pockets play an important role in biological processes and are of pharmaceutical importance. Therefore, the calculation of the ligand SBFE with such proteins is an important challenge. In this work, we developed a hierarchical approach to compute SBFE of a flexible multi-conformational system as an ensemble average of individual local SBFEs to specific conformational states of the protein-ligand complex. This approach allows us to simulate a truncated portion of a large protein, which brings an intractable system within the reach of modern computational tools. Our approach also accounts for the differences in conformational preferences between a ligand-bound and an apo states of the protein. The approach is validated using the T4 lysozyme mutant in complex with a small molecule inhibitor. Binding energies of a non-competitive antagonist (GYKI) with the GluA2 glutamate receptor of AMPA type (AMPAR) are computed for several poses of GYKI in the binding pocket to help facilitate structure validation at relatively low resolution.

Published: November 2024

This study introduces a method for synthesizing electrically conductive hydrogels with a self-assembled, percolating graphene network, overcoming traditional challenges of integrating conduc-tive fillers into hydrogels. By using pristine graphene at the oil-water interface to stabilize a water-in-oil emulsion, we successfully developed hydrogel foams with conductivity up to 15 mS/m and tunable porosity. The concentration of monomer and graphite in the emulsion was optimized to control the cell size, stability, and swelling behavior of the final hydrogels, offering versatility in structure and functionality. Electrical conductivity and thermogravimetric analysis (TGA) con-firmed the stability and conductive properties imparted by the graphene network. This method demonstrates a cost-effective route to conductive hydrogels, making them promising candidates for applications in sensors, energy storage, bioelectronics, and other advanced technologies.

Published: November 2024

We present a new parameterization of the ChIMES physics informed machine- learned interatomic model for simulating carbon under conditions ranging from 300 K and 0 GPa to 10,000 K and 100 GPa, along with a new multi-fidelity active learning strategy. The resulting model shows significant improvement in accuracy and temperature/pressure transferability relative to the original ChIMES carbon model developed in 2017, and can serve as a foundation for future transfer-learned ChIMES parameter sets. Model applications to carbon melting point prediction, shockwave-driven con- version of graphite to diamond, and thermal conversion of nanodiamond to graphitic nanoonion are provided. Ultimately, we find our new model to be robust, accurate, and well-suited for modeling evolution in carbon systems under extreme conditions.

Background. Combination therapy is the standard of care for intermediate and poor prognosis metastatic renal cell carcinoma. In the IMDC prognostic classification, tumor stage and histological type are not considered due to the lack of independent impact on overall survival. The CLEAR study demonstrated the efficacy of lenvatinib and pembrolizumab combination in long-term treatment outcomes, including overall survival in poor prognosis compared to sunitinib. The KEYNOTE-B61 study demonstrated high efficacy of this combination in patients with non-clear cell renal cell carcinoma.
Aim. To evaluate the efficacy of the combination of lenvatinib and pembrolizumab in patients with high tumor burden and non-clear cell histotypes.
Materials and methods. This prospective observational study included 54 patients with metastatic renal cell carcinoma who received a combination of lenvatinib and pemrolizumab in the first line between 2022 and May 2024 in oncology clinics of the Moscow Department of Health. Clear cell histotype was represented in 79.6% of cases, 14.8% had papillary cancer, and 5.6% of patients had chromophobe cancer. The primary endpoint was the objective response rate.
Results. The objective response was assessed in 50 patients. The objective response rate was 38%, including 2% complete response according to RECIST 1.1, disease progression was in 8% of patients. The median depth of response was -25% (from -100% to +28). The median time to response was 12.4 weeks (1.1–38.3).
Conclusion. The efficacy of the combination of lenvatinib and pembrolizumab in real-life clinical practice outside the inclusion criteria of the CLEAR study is clinically significant and allows us to expect improvement even in patients with a large volume of metastatic process and non-clear cell histotype, but the expected benefit in patients with unsatisfactory somatic status remains disputed.
