Authors: Takeshima Yasuhiro , Takami Hirokazu , Endo Toshiki , Mizuno Masaki , Hida Kazutoshi ,   for the Investigators of Intramedullary Spinal Cord Tumors in the Neurospinal Society of Japan
Published: September 2023

Objective: This study aimed to clarify the relationship between recurrence and the extent of resection in surgery for intramedullary spinal hemangioblastoma (sHB) and its impact on von Hippel-Lindau (vHL) disease.Methods: Data on sHB cases followed up for at least 6 months after surgery were extracted from a nationwide registry of 1,033 consecutive spinal intramedullary tumors surgically treated between 2009 and 2020, and were retrospectively categorized into a sporadic or vHL group. The diagnosis of vHL disease was made at each institution based on clinical findings.Results: A total of 168 patients (sporadic group, 101; vHL group, 67) were included in the study. Compared with the sporadic group, the vHL group had a younger onset (45.4 ± 16.8 years vs. 39.6 ± 14.1 years, p = 0.02), more preoperative motor (47.5% vs. 68.7%, p < 0.01) and gait (37.6% vs. 61.2%, p < 0.01) impairments, and more patients with worsening neurological symptoms at discharge (p = 0.02). The gross total resection (GTR) rates and the recurrence rates were not statistically different between the sporadic and the vHL groups. GTR significantly improved recurrence-free survival compared to non-GTR in all patient analysis (p < 0.01) but this trend was not observed in the sporadic group. Physical functional improvement from discharge to 6 months after surgery was observed in the sporadic group (p < 0.01) but not in the vHL group.Conclusion: A high GTR rate may sufficiently decrease susceptibility to recurrence, especially in patients with sHB with vHL. In sporadic sHB, postoperative functional improvement can be expected, and the long-term functional prognosis is favorable.

Authors: Wang Shengru , Zhao Yiwei , Lin Guanfeng , Du You , Yang Yang , Zhang Jianguo
Published: September 2023

Objective: Based on traditional dual growing rods (TDGR), apical control techniques (ACTs) were introduced as adjuvant procedures to improve deformity correction at the apex segment in the treatment of early-onset scoliosis (EOS). We aimed to explore whether TDGR+ ACTs have different indications, attain more deformity correction, have negative effects on spinal growth, and have different complications.Methods: Between 2004 and 2019, a retrospective study of EOS patients treated with TDGR with or without ACTs was conducted and divided into 3 groups: TDGR group; hybrid technique (HT) group: Vertebrectomy/hemivertebrectomy with short fusion and TDGR; ACPS group: apical convex control pedicle screws (ACPS) and TDGR. Demographic, radiographic parameters, clinical outcomes, complications, and revisions were analyzed and compared.Results: Seventy-eight EOS patients were enrolled. The preoperative main curve was the largest in the HT group. ACPS group had the smallest residual curve (19° ± 8.9°) and apical vertebral translation (12.0 ± 9.0 mm) at the latest follow-up, followed by the HT group (30° ± 17.4°, 22.1 ± 13.4 mm) and TDGR group (30° ± 13.2°, 32.8 ± 17.1 mm). ACPS group had the largest T1–12 height and T1–S1 height after index surgery. Complications and revisions in the ACTs groups was lower than the TDGR group. Scoliosis Research Society-22 self-image questionnaire was superior in the ACPS group.Conclusion: According to our intermediate results, TDGR+ACTs could improve correction ability of apex deformity. ACTs had little deleterious effects on spinal height during the lengthening procedures, with a lower complication rate than TDGR. TDGR+ACTs might be a supplemental option for suitable EOS patients.
Introduction of a New Radiographic Parameter to Predict Proximal Junctional Kyphosis in Adult Spinal Deformity: UIVPTA (Uppermost Instrumented Vertebra-Pelvic Tilt Angle)
Authors: Park Se-Jun , Lee Chong-Suh , Park Jin-Sung , Shin Tae Soo
Published: September 2023

Objective: To introduce a new sagittal parameter, uppermost instrumented vertebra-pelvic tilt angle (UIVPTA), and to determine the effects on the proximal junctional kyphosis (PJK) development in adult spinal deformity (ASD) surgery.Methods: Patients ≥ 60 years with ASD who underwent low thoracic spine to pelvis fusion with a minimum of 2-years of follow-up were included in this study. Two groups were created according to PJK development. Various clinical and radiographic factors were compared between PJK and non-PJK groups to identify the risk factors for PJK. Cutoff value of UIVPTA for PJK development was calculated using receiver operating characteristic curve according to different pelvic incidence groups. Linear regression analysis was performed to identify factors to affect UIVPTA.Results: One hundred fifity-one patients were included in this study. There were 135 female patients (89.4%). Mean age was 70.5 years. PJK developed in 65 patients (43.0%). Multivariate analysis showed that overcorrection relative to age-adjusted pelvic incidence (PI) minus lumbar lordosis (LL) (PI–LL) target and lower UIVPTA were independent risk factors for PJK. The cutoff value of UIVPTA for PJK development was calculated as 4.0° in patients with PI less than 45°, 9.5° in patients with PI between 45° and 60°, and 13.0° in patients with PI greater than 60°. Linear regression analysis showed that UIVPTA was positively affected by postoperative values of LL (coefficient = 0.505), PI–LL (coefficient = 0.674), and pelvic tilt (coefficient = 0.286).Conclusion: Optimal correction within the age-adjusted PI–LL combined with keeping UIVPTA within optimal range is suggested for the prevention of PJK.

Authors: Jiang Lei , Budu Alexandru , Khan Muhammad Shuaib , Goacher Edward , Kolias Angelos , Trivedi Rikin , Francis Jibin
Published: September 2023

Objective: We aim to compare the effectiveness of dural closure techniques in preventing cerebrospinal fluid (CSF) leaks following surgery for intradural lesions and seek to identify additional factors associated with CSF leaks. Surgical management of spinal intradural lesions involves durotomy which requires a robust repair to prevent postoperative CSF leakage. The ideal method of dural closure and the efficacy of sealants has not been established in literature.Methods: We performed a retrospective analysis of all intradural spinal cases performed at a tertiary spine centre from 1 April 2015 to 29 January 2020 and collected data on patient bio-profile, dural repair technique, and CSF leak rates. Multivariate analysis was performed to identify predictors for postoperative CSF leak.Results: A total of 169 cases were reported during the study period. There were 15 cases in which postoperative CSF leak was reported (8.87%). Multivariate analysis demonstrated that patient age (odds ratio [OR], 0.942; 95% confidence interval [CI], 0.891–0.996), surgical indication listed in the “others” category (OR, 44.608; 95% CI, 1.706–166.290) and dural closure with suture, sealant and patch (OR, 22.235; 95% CI, 2.578–191.798) were factors associated with CSF leak. Postoperative CSF leak was associated with the risk of surgical site infection with a likelihood ratio of 8.704 (χ² (1) = 14.633, p < 0.001).Conclusion: Identifying predictors for CSF leaks can assist in the counselling of patients with regard to surgical risk and expected postoperative recovery.

Published: September 2023

Adolescent idiopathic scoliosis (AIS) affects approximately 2% of adolescents across all ethnicities. The objectives of surgery for AIS are to halt curve progression, correct the deformity in 3 dimensions, and preserve as many mobile spinal segments as possible, avoiding junctional complications. Despite ongoing development in algorithms and classification systems for the surgical treatment of AIS, there is still considerable debate about selecting the appropriate fusion level. In this study, we review the literature on fusion selection and present current concepts regarding the lower instrumented vertebra in the selection of the fusion level for AIS surgery.
Relationships Between Skeletal Muscle Mass, Lumbar Lordosis, and Chronic Low Back Pain in the Elderly
Authors: Park Myung Woo , Park Sang Jun , Chung Sun Gun
Published: September 2023

Objective: Loss of skeletal muscle mass is known to be associated with multiple morbidities. However, there is a dearth of reports on its association with lumbar lordosis and musculoskeletal pain. The aim of this study was to delineate the cross-sectional relationship between loss of skeletal muscle mass, lumbar lordosis, and chronic low back pain (CLBP).Methods: A total of 721 medical records were reviewed, and data from 165 older subjects (over 65 years old; 81 men and 84 women) were retrospectively analyzed. Subjects were categorized into either the CLBP group (back pain for more than 6 months; 35 men and 36 women) or the control group (46 men and 48 women). The modified skeletal muscle mass index (MSMI, appendicular skeletal muscle mass [kg]/weight [kg] × 100), assessed by bioelectrical impedance analysis, and lumbar lordotic angle (LLA) were measured and compared between the CLBP group and the control group. The correlation between MSMI and LLA was investigated.Results: The LLA of men and women in the CLBP group was significantly lower than that of the control group (p < 0.05). The MSMI was decreased in the CLBP group compared to the control group (p < 0.05). For both sexes, positive correlations were observed between the MSMI and LLA.Conclusion: A close cross-sectional relationship was observed between MSMI, LLA, and CLBP. This suggests a potential interaction between the reduction in skeletal muscle mass and altered lumbar spine sagittal alignment, which could lead to CLBP.

Published: September 2023

Objective: This study aimed to investigate the correlation between ossification of the posterior longitudinal ligament (OPLL) size and multifidus fatty degeneration (MFD), hypothesizing that larger OPLL sizes are associated with worse MFD.Methods: One hundred four patients with cervical OPLL who underwent surgery were screened. OPLL occupying diameter and area ratios, the severity of MFD using the Goutallier classification, and range of motion (ROM) of cervical flexion-extension (ΔCobb) were measured. Correlation analyses between OPLL size, MFD severity, and ΔCobb were conducted. MFD severity was compared for each OPLL type using one-way analysis of variance.Results: The final clinical data from 100 patients were analyzed. The average Goutallier grade of C2–7 significantly correlated with the average OPLL diameter and area occupying ratios, and OPLL involved vertebral level (r = 0.58, p < 0.01; r = 0.40, p < 0.01; r = 0.47, p < 0.01, respectively). The OPLL size at each cervical level significantly correlated with MFD of the same or 1–3 adjacent levels. ΔCobb angle was negatively correlated with the average Goutallier grade (r = -0.31, p < 0.01) and average OPLL occupying diameter and area ratios (r = -0.31, p < 0.01; r = -0.35, p < 0.01, respectively). Patients with continuous OPLL exhibited worse MFD than those with segmental OPLL (p < 0.01).Conclusion: OPLL size is clinically correlated with MFD and cervical ROM. OPLL at one spinal level affects MFD at the same and 1–3 adjacent spinal levels. The worsening severity of MFD is associated with the longitudinal continuity of OPLL.

Authors: Takahashi Shinji , Inose Hiroyuki , Tamai Koji , Iwamae Masayoshi , Terai Hidetomi , Nakamura Hiroaki
Published: September 2023

Osteoporotic vertebral fractures (OVFs) can hinder physical motor function, daily activities, and the quality of life in elderly patients when treated conservatively. Vertebral augmentation, which includes vertebroplasty and balloon kyphoplasty, is a commonly used procedure for OVFs. However, there have been reports of complications. Although serious complications are rare, there have been instances of adjacent vertebral fractures, cement dislocation, and insufficient pain relief due to cement failure, sometimes necessitating revision surgery. This narrative review discusses the common risks associated with vertebral augmentation for OVFs, such as cement leakage and adjacent vertebral fractures, and highlights the risk of revision surgery. The pooled incidence of revision surgery was 0.04 (0.02–0.06). The risks for revision are reported as follows: female sex, advanced age, diabetes mellitus, cerebrovascular disease, dementia, blindness or low vision, hypertension, hyperlipidemia, split type fracture, large angular motion, and large endplate deficit. Various treatment strategies exist for OVFs, but they remain a subject of controversy. Current literature underscores the lack of substantial evidence to guide treatment strategies based on the risks of vertebral augmentation. In cases with a high risk of failure, other surgeries and conservative treatments should also be considered as treatment options.

Published: September 2023

Objective: Although endoscopic drill has the advantages in manipulation and hemostasis, whose low efficiency and blurred vision reduce the efficacy of lumbar endoscopic unilateral laminotomy with bilateral decompression (LE-ULBD). The present study was designed to evaluate the safety and efficacy of full-visualized trephine/osteotome in the LE-ULBD surgery for severe lumbar stenosis.Methods: Fifty-seven severe lumbar stenosis patients who underwent LE-ULBD between January 2020 to January 2023 were enrolled, who were divided into drill and visualized trephine groups. The medical records including demographics, operative duration, intraoperative electrophysiological findings, postoperative hospital stay or hospital stay, postoperative outcomes and complications were retrospectively reviewed and analyzed.Results: A total of 57 patients included 15 in drill and 42 in trephine group were enrolled in the study. There was significant difference in the pre- and postoperative visual analogue scale and Oswestry Disability Index scores in both groups (p < 0.05). The mean operative duration in the trephine group (101.05 ± 12.18 minutes) was shorter than that in the drill group (134.67 ± 9.68 minutes) (p < 0.05). There was no statistical difference between the 2 groups in electrophysiological monitoring, posthospital stays, postoperative outcomes and complications. Abnormal free-electromyography (EMG) were recorded in 2 (13.3%) and 5 patients (11.9%) in the drill and trephine group. Intraoperative somatosensory evoked potential changes occurred in 3 (20%) and 3 patients (7.1%) in the drill and trephine group and all patients recovered immediately when surgery ended. No serious complications and recurrence occurred in all the patients.Conclusion: Full-visualized trephine/osteotome has been approved to be convenient, safe and efficient in our study, which combined with translaminar inside-out technique and EMG monitoring especially free-EMG may offer a new choice in LE-ULBD surgery for lumbar stenosis patients.
“A Great Warrior In Battle”
Authors: Anderson Devery S.
Published: September 2023

This chapter acknowledges the horrific violence against some Black people in Hattiesburg where Clyde Kennard grew up. It highlights the tragedy of dying at the hands of southern lynch mobs. The backlash to Brown v. Board of Education of Topeka and Black voter activism led to the first documented lynchings in the state since 1951. The chapter also covers Kennard's aspirations to defend his country in the military and, subsequently, fight for his rights. It mentions the national spotlight on Dr Martin Luther King Jr and rampant discrimination involving segregation on public transportation in the American consciousness. Many Black veterans came away more determined to fight the system that had kept them down.
“History Is In The Making”

Published: September 2023

This chapter discusses Clyde Kennard becoming the first Black student of the Mississippi Southern College. Kennard took advantage of the postwar boom in college enrollment in the United States due to the passage of the Servicemen's Readjustment Act of 1944. After the Jim Crow laws in Mississippi, any attempt by an African American to enroll at Mississippi Southern College would be unprecedented and met with all-out resistance. The chapter details every effort Kennard made to attempt to enter the college, which resulted in the state feeling justified in using all resources at its disposal to stop him. The chapter mentions that Kennard was on the radar of the governor and under investigation by the Sovereignty Commission.
“To Follow A Reasonable Course”

This chapter focuses on FBI agent Zack Van Landingham's investigation of Clyde Kennard. The chapter details Van Landingham's work with James H. White, William D. McCain, Black school principals Nathaniel Burger and Clarence Roy to prevent Kennard from attending Mississippi Southern College. Kennard was still a focus of the Sovereignty Commission, even if he was not then making noise about attending Mississippi Southern College. The chapter explains that Kennard did his best to counter the issues the school used in denying him admission. It cites that his worries entering college seemed trivial after his arrest for allegedly owning hard liquor in Mississippi.
La notion de linéaments chez Alberti
Authors: Helali Imen
Published: September 2023

Si les textes s’éclairent à lumière indirecte de leur contexte et de leur intertexte, le sens propre de leur message n’est saisissable que dans le réseau des paraphrases et des périphrases qu’ils énoncent eux-mêmes ; les textes s’auto-expliquent. Imen Helali interroge la signification du vocable linéaments dans le De re aedificatoria. Prolongeant les discussions terminologiques qu’a suscitées l’usage de ce mot par Alberti, elle propose une lecture systématique et croisée de deux passages du premier livre et du prologue. Produisant des échos loin dans le texte du traité, elle fait entendre la nature à la fois mentale et formelle des linéaments et réfute la thèse de Susan Lang selon laquelle il s’agirait de « plans de sol », d’une représentation graphique des édifices projetés sur un plan horizontal. Confrontant sa lecture à celles des nombreux spécialistes qui se sont penchés sur la question, Imen Helali déplace les lignes d’interprétation du texte d’Alberti et produit quelques avancées notables dans la théorie de l’architecture.

Imen Helali est architecte, diplômée par l’Ecole Nationale d’Architecture et d’Urbanisme (ENAU) de l’Université de Carthage (Tunisie) et détentrice d’un Master de Recherche en Architecture. Depuis 2019, elle conduit une thèse de doctorat sur le thème des limites à l’ENAU et au Département de Langues et Littératures françaises et romanes de l’Université de Liège (Belgique).

Architecture, corps et sublimation
Authors: Melo Saint-Cyr Viviana
Published: September 2023

« Élever un objet à la dignité de la Chose ». Cette formule de Lacan, qui vise la sublimation, ordonne le développement du texte de Viviana Melo Saint-Cyr que nous publions en cette fin de décembre : « Architecture, corps et sublimation ». C’est très précisément l’articulation du corps et de l’architecture, tel que l’idée psychanalytique de sublimation permet de la pointer, qui guide le travail de Viviana M. Saint-Cyr. Les théoriciens-architectes de la Renaissance (Alberti, Filarete, etc.), l’histoire de l’art (Wölfflin), la psychanalyse « freudienne » (Freud, Groddeck, Rank, etc.), la psychanalyse « lacanienne » (Lacan, Wajcman) sont appelés au fil d’une enquête et d’une construction exigeantes. La contribution est réellement inédite et nourrira — avec Évidence — de futures discussions ; ce texte est une partie adaptée du travail de thèse de Viviana M. Saint-Cyr, mené sous la direction de Gérard Wajcman. Voici un extrait de l’article publiée ce mois : « La théorie freudienne du narcissisme met le monde à sa place, “à savoir dans notre corps et pas ailleurs”. Le narcissisme structure “toutes les relations de l’homme avec le monde extérieur” ; tous les objets du monde humain, y compris les figures géométriques, ont un caractère fondamentalement anthropomorphique. Nous insistons sur ceci que dans la formule vitruvienne, qui ne désespère de trouver la cohérence universelle, se trouve le fondement du stade du miroir de l’architecture : l’harmonie entre le corps humain et les figures géométriques “parfaites” — qui implique une certaine correspondance entre mon corps-tenu et l’univers — en est la base. »
Notes pour une théorie d’un paysage habité
Authors: Cloquette Pierre
Published: September 2023

Le "paysage" compte parmi ces concepts qui s'usent à mesure d'un emploi excessif. Pratiqué par les savants de diverses disciplines - et surtout par les adeptes de l'interdisciplinarité - comme par les praticiens du territoire et de l'architecture, sa cible disparaît, à force, dans une brume qui dissout sa pointe. Instance de la nature dans le monde artificiel, construction culturelle qui s'approprie l'altérité, dispositif esthétique propre à l'occident, artialisation de l'environnement, parcs et jardins, forme sensible des territoires,... On ne peut mieux s'entendre à se mal comprendre ! Il est l'heure de tenter un bilan et d'établir si le "paysage" dispose de vertus opératoires à suffisance dans les champs conjoints de la pratique et de la théorie de l'architecture.L'article que nous publions en ce mois de décembre participe d'un tel essai : « Notes pour une théorie du paysage habité » est écrit par Pierre Cloquette. Rebondissant sur une lecture critique des travaux d'Augustin Berque, l'auteur explicite les apories où s'enferment les saisies esthétiques et techniques du paysage pour ouvrir celui-ci au thème de l'habiter, dont les approches menées par Martin Heidegger et Georges-Hubert de Radkowski attendent encore d'être poursuivies avec sérieux. « L'homme transformant toujours déjà , et en même temps, l'étendue terrestre comme sa représentation, cette dernière prend également pour objet le produit d'une transformation matérielle – de sorte qu'il n'est pas possible de distinguer ce qui serait de l'ordre de la transformation de ce qui serait de l'ordre du « fond » originaire et rend caduque toute spécification du paysage par sa proximité d'avec la nature.»

Background: The new coronavirus disease has accelerated the development of therapeutic guidelines for patients depending on their degree of severity. To date, many drugs have been studied. However, as time passed, only some of these therapeutic groups have been effective and have produced a reduction in patient mortality and morbidity. Methods: A search and identification of articles published in the following electronic data-bases was carried out: PubMed, Clinical Key, Web of Science, and Scopus; for their analysis and selection in English and Spanish. The literature research emphasizes the search for current guidelines on the treatment of COVID-19, including all degrees of severity, seeking the effectiveness of the medication. Results: For each listed drug, its pharmacodynamics, pharmacokinetics, and general re-commendations for use in adult patients with COVID-19, are described. Conclusions: Du-ring the COVID-19 pandemic, numerous groups of drugs have been studied, however, only a select group have shown to have a role in the treatment of the disease. The literature and guidelines support the use of these treatments.

Published: September 2023

La demencia tipo Alzheimer (DTA) es una enfermedad neurodegenerativa que impacta funciones como memoria y cognición, entre otras, así como en el nivel de dependencia funcional de los pacientes. El siguiente artículo es un ejercicio de abstracción clínico y narrativo que pretende realizar una reflexión sobre el corto animado Mémorable del director Bruno Collet, el cual detalla la experiencia de un hombre cursando con DTA, con los siguientes objetivos: aplicar algunas herramientas de estadificación del deterioro cognitivo en DTA; contrastar el cuadro clínico demostrado en la cinta con la experiencia de William Utermohlen, un artista que continuó trabajando aún después de ser diagnosticado con dicha condición; y reflexionar sobre la utilidad del cine como instrumento de medicina narrativa y recurso académico para los profesionales de la salud en formación, con el fin de recuperar aspectos humanos de la vida de estos pacientes, evaluando cómo su creatividad persiste pese a su deterioro.
Relación entre el bienestar, deterioro cognitivo, afrontamiento al estrés y actividad física durante la pandemia por COVID-19 en personas mayores de una ciudad del norte de Chile
Authors: Jorquera Cáceres Ivonne , Guzmán Muñoz Eduardo , Vega Palma Margarita
Published: September 2023

Objetivo: Determinar si existe relación entre las medidas de afrontamiento, nivel de actividad física y el bienestar de personas mayores con deterioro cognitivo leve frente a las personas sin deterioro cognitivo en situación de pandemia por COVID-19. Metodología: Estudio transversal que incluyó a 65 personas mayores que viven en la comunidad de Arica. Su rendimiento cognitivo fue evaluado con la evaluación cognitiva de Montreal (MoCA), sus estrategias de afrontamiento al estrés se midieron con el Inventario Multidimensional de Estimación del Afrontamiento (COPE -28), sus niveles de actividad física con el cuestionario internacional de actividad física (IPAQ), y su bienestar mediante el cuestionario de salud general GHQ12. Resultados: cuatro variables se comportaron de manera significativa como predictores de bajo bienestar: tener sexo femenino (B=-1,833; p=0,0495); edad cercana a los 60 años (B=-0,175; p=0,0305); usar bloqueo del afrontamiento al estrés (B=0,706; p=0); y usar menos Afrontamiento cognitivo (B=-0,436; p=0,001). Además, existió una significativa relación entre bajo bienestar y menor cantidad de METS en el grupo de actividad física moderada (p 0,022). Conclusión: La mayor prevalencia de bajo bienestar se observó en participantes con menor actividad física, género femenino y que utilizan el bloqueo de afrontamiento como estrategia a periodos de estrés. Estos resultados indican que es vital asegurar que las personas mayores permanezcan activas, y mantengan adecuadas medidas de afrontamiento, para ser más resilientes durante una crisis.

Published: September 2023

The commercial farming of juvenile lumpfish requires monitoring of gonadal development to achieve synchronized production. Conventional methods such as gonadosomatic index (GSI), sex hormone analyses, gonadal histology, endoscopy, and gene expression analyses are costly, invasive, and often involve sacrificing the fish. We assessed the efficiency of ultrasound as a non‐invasive method for monitoring gonadal development in lumpfish. Based on ultrasound observations, we categorized the fish into six stages; F0 to F5 for females and M0 to M5 for males, that represented maturity levels from immature to spent. Importantly, the ultrasound gonadal stages aligned with histological gonadal stages. Additionally, ultrasound stages aligned with profiles of GSI, testosterone (T), 11‐ketotestosterone, and 17β‐estradiol throughout gonadal development including the spawning period. Moreover, these parameters exhibited significant positive correlations with each other reflecting their parallel trends during gonadal development. To minimize the frequency of ultrasound usage and fish handling, we established F3 and M3/M4 as arbitrary thresholds for identifying ripe females and males, respectively. By using these thresholds, the need for regular ultrasound monitoring could be reduced during most of the rearing period. Ultrasound proves to be useful and reliable for monitoring gonadal development in lumpfish, enabling synchronized production of juvenile fish.
Heart rate variability in male rats
Authors: Švorc Pavol , Grešová Soňa , Švorc Pavol
Published: September 2023

The cardiovascular system is primarily controlled by the autonomic nervous system, and any changes in sympathetic or parasympathetic activity also have an impact on myocardial activity. Heart rate variability (HRV) is a readily available metric used to assess heart rate control by the autonomic nervous system. HRV can provide information about neural (parasympathetic, sympathetic, reflex) and humoral (hormones, thermoregulation) control of myocardial activity. Because there are no relevant reference values for HRV parameters in rats in the scientific literature, all experimental results are only interpreted on the basis of changes from currently measured control or baseline HRV values, which are, however, significantly different in individual studies. Considering the significant variability of published HRV data, the present study focused primarily on comparing control or baseline HRV values under different conditions in in vivo experiments involving rats. The aim of the study was therefore to assess whether there are differences in the starting values before the experiment itself.

In this study, Indocalamus micro/nanofibers (IMFs) were extracted from natural Indocalamus leaves by physical processing and alkaline treatment. IMFs reinforced epoxy resin (EP) and their carbon-fiber composites (IMFs/CFRP) were fabricated. The effects of IMF on the mechanical properties of the EP and CFRP composites were studied. Infrared spectroscopy and scanning electron microscopy (SEM) were used to characterize the functional groups and microstructure of IMF, EP, and CFRP. The experimental results showed that the strength of the EP increased as the IMF content increased from 0% to 20%, but on further increase in IMF content of 25%, the strength of the EP reduced. In addition, the mechanical properties of the IMF/CFRP were slightly higher as compared with the control CFRP. The SEM observations on IMFs/EP and IMFs/CFRP composites reveal that the alkali-treated IMFs facilitate the interfacial interlocking structure and improve the interfacial adhesion of the composites.

A RUÍNA COMO RESISTÊNCIA EM FLORIANÓPOLIS
Authors: Fiorin Evandro , Freitas Djonathan
Published: September 2023

Este artigo tem como objetivo explorar o conceito de cartografia como desvio na cidade, a partir das práticas cotidianas do sujeito e território, demonstrando a importância histórica e cultural de Florianópolis e, para isso, foram realizadas cartografias narrativas. Assim, por meio do caminhar como prática estética, buscamos por um encontro com o Outro; traçamos atalhos, desvios, reinventando os lugares e ocupando espaços conforme nos deslocamos a pé ou de bicicleta. Aqui, ressaltamos a importância dessa paisagem que legitima as edificações em ruínas, para a construção de identidades, diante da necessidade de sua permanência, sem que haja um rejuvenescimento arquitetônico. Como resultados, construímos uma discussão sobre a percepção do patrimônio e da paisagem cultural, tendo em vista os conceitos e os processos de percepção que revelem as surpresas dessas ruínas como resistência desse lugar para a constituição de um novo olhar.
ESPAÇO TRILHAR

Published: September 2023

A história de Santa Maria é fortemente associada à Viação Férrea do Rio Grande do Sul, atribuindo um período de grande desenvolvimento da cidade ao auge da ferrovia. Das especificidades do fazer ferroviário, Santa Maria registrou a construção de muitos equipamentos para servir à ferrovia e tantos outros em função do contingente de pessoas que se relacionavam, ou se beneficiavam pela atividade. O olhar aqui exposto aproxima-se do Clube dos Ferroviários como um desses equipamentos que fora por muito tempo esquecido, apresentando-o na sua situação de abandono físico (edifício em ruínas) e abandono de classe (elite ferroviária que não existe mais), compartilhando aspectos que foram considerados ao assumi-lo como tema de Trabalho Final de Graduação em Arquitetura e Urbanismo. No recorte de texto, transita-se pela história de Santa Maria, apresentam-se as condições do edifício atualmente e expõe-se a proposta do Centro Multiuso chamado Espaço Trilhar como uma projeção de futuro.
CORPOESPAÇOTEMPO DO ABANDONO

Published: September 2023

O presente artigo visa dar visibilidade a corpos, espaços e tempos indissociadamente e associados a abordagens interdisciplinares do abandono enquanto invisibilidade na contemporaneidade. O corpoespaçotempo é uma correspondência entre os diversos componentes básicos de subsistência do indivíduo por diferentes escalas e relações políticas e intersetoriais, bem como produz uma alusão aos conhecimentos referentes às visibilidades, aos direitos e a representatividade de parcelas da população, com foco na mulher, em debates feministas e acerca da alteridade. Os diferentes tipos de abandono estão presentes no cotidiano das minorias, no viés rotineiro da exclusão, da subordinação e da discriminação em corpos a espaços e tempos. Os debates teóricos e as práticas extensionistas aqui apresentadas, desenvolvidas junto ao Fórum de Mulheres das Vertentes, permitem uma percepção atualizada daquilo que é vago, marginalizado e degradado nos dias atuais, evidenciando reincidências em negligências de corpos em relações espaço-temporais e sociais invisibilizadas de modo inter- relacionado e interseccional.
ABANDONO DO PATRIMÔNIO INDUSTRIAL
Authors: Alves Isadora , Montagna da Silveira Aline
Published: September 2023

Ao longo do tempo, os processos industriais podem passar por uma série de transformações, seja com os avanços tecnológicos, ou pelo surgimento de novas práticas. Assim, os núcleos e edificações fabris que compõem um complexo industrial estão sujeitos à passar pelo processo de obsolescência de determinados usos e funções. Este fato acarreta no arruinamento ou perda total dos bens que integram essa ambiência. Neste sentido, o objetivo deste trabalho é analisar a situação de abandono das ruínas da Vila de Santa Thereza, localizada em Bagé no Rio Grande do Sul a partir da premissa da obsolescência dos espaços fabris e apresentar a importância do reconhecimento e da salvaguarda dos exemplares da arquitetura industrial, em consonância com as reflexões contemporâneas do campo disciplinar. O método de análise constitui-se a partir de uma investigação através de revisão bibliográfica atrelada a análise de levantamento fotográfico realizado in loco. Em Santa Thereza, apesar de legislações existentes no âmbito estadual e municipal, constata-se a falta de ações efetivas de preservação, o que pode ser adquirido com o envolvimento das comunidades nos processos de patrimonialização.
PATRIMÔNIO ESCOLAR EM ABANDONO

No Rio Grande do Sul, na primeira metade do século XX, a demanda por prédios escolares foi atendida através de escolas padrão, que atualmente podem ser consideradas símbolos da memória coletiva. Desse modo, é importante a preservação desse patrimônio, que guarda a narrativa de formação das cidades, como também comunica e mantém a continuidade da identidade e cultura de uma região. Entretanto,alguns exemplares dessas instituições, construídas em 1940, não foram preservados e estão em processo de abandono. Por meio dos múltiplos significados de abandono nessa situação, este artigo tem o objetivo de identificar narrativas que auxiliem os processos de reconhecimentos de bens a serem preservados. Através de estudo de caso, com a metodologia da História Oral Temática, em uma escola com projeto padrão, em Rio Grande/RS, que foi demolida, foi verificado o abandono da função pedagógica, além do descaso com a comunidade escolar e a perda do lugar.
AVALIAÇÃO DA DEGRADAÇÃO DE FACHADAS ATRAVÉS DE IMAGENS DO STREET VIEW
Authors: Pasqualotti Fernanda , Aurich Mauren , Da Silva Torres Ariela
Published: September 2023

Santo Ângelo é conhecida por suas tradições, devido à diversidade étnica e cultural dos povos que ali se estabeleceram há aproximadamente três centenas atrás. No entanto, apesar do interesse cultural gerado por seus prédios históricos, existem vários sem manutenção, demonstrando a ausência de preocupação com a preservação do patrimônio. As fachadas das edificações deterioram-se devido ao envelhecimento natural e, os métodos existentes para avaliar essa degradação utilizam fotos das edificações. Além das fotos feitas in loco, elas também podem ser obtidas através do Street View. O objetivo deste estudo é avaliar a aplicabilidade das imagens adquiridas através do Street View nos métodos Mapa de Danos e Mensuração de Degradação. O estudo observou que as imagens obtidas pelo Street View não possuem qualidade suficiente para serem aplicadas. Entretanto, através dele, foi possível criar uma linha do tempo de degradação, observando-se que, com uma manutenção inadequada, há um aumento na intensidade das manifestações patológicas.
RESTAURAÇÃO DO MERCADO PÚBLICO CENTRAL, PELOTAS/RS
Authors: De Oliveira Viana Jorge Luiz
Published: September 2023

A partir da restauração do Mercado Público Central de Pelotas/RS, Edital para Concorrência nº 02/2008, há um bom exemplo para pensar a restauração de uma edificação histórica, de grande significância material e imaterial, com primazia ao aspecto arquitetônico. Juntos, o Ministério da Cultura e o Instituto do Patrimônio Histórico e Artístico Nacional, conceberam e executaram o projeto sem considerar o trabalho arqueológico cabível e, também, sem os estudos antropológicos necessários para identificar e interpretar as representações culturais na área. Portanto, esse ensaio propõe, mais do que apresentar as atividades contingenciadas da Arqueologia e Antropologia, chamar a atenção para a dimensão participativa dessas disciplinas no desenvolvimento de projetos arquitetônicos para restauração ou revitalização. Concluise que esta é uma proposta desafiadora e urgente para que a academia adeque seus planos de ensino à interdisciplinaridade, para que no futuro tenhamos profissionais atuando numa perspectiva ampliada da significância cultural.
FISSURADA

Published: September 2023

Este artigo trata do abandono como um acontecimento: o desabitar recente do bairro de Bebedouro na cidade de Maceió/AL, ocasionado pelo agravamento das consequências da mineração de longa data de sal-gema em região da cidade. Deparamo-nos aqui com um lugar de memória, que passou por transformações profundas e que atualmente se apresenta por rastros tangíveis e intangíveis de outros tempos, evidenciando circunstâncias traumáticas que propiciaram a desestruturação e descontinuidade de seus modos de habitar. A partir de revisão e análise documental, observação empírica e análises de conteúdo, privilegiou-se imagens de diferentes tempos e fontes para construir o conceito de fissura enquanto polissemia que nos permite interpretar e relacionar reverberações históricas e socioambientais desse acontecimento: o que quebrou, o que não resistiu, o que persistiu, o que se construiu pelos efeitos de uma força que compôs uma memória traumática.
A MEMÓRIA DO VAZIO CONTRA O VAZIO DA MEMÓRIA
Authors: Paim Flora
Published: September 2023

Aborda-se a metodologia do arquivo na arte contemporânea para problematizar as tensões subjacentes ao registro da memória, sobretudo urbana. Parte-se da genealogia do conceito de arquivo, em formulações inspiradas pelo archival turn observado nas ciências sociais e humanas a partir dos anos 1990, e da análise de dois projetos artísticos que investigam as histórias relacionadas a um descampado localizado no Porto/PT. Neste terreno existia um dos primeiros conjuntos de habitação social da cidade, erigido nos anos 1940, em uma zona urbana então periférica, e demolido nos anos 2000. Diante da destruição do lugar e da sua sub-representação nos arquivos oficiais, faz-se necessário discutir a relação entre as operações de reestruturação urbana e a parcialidade dos registros dominantes sobre o passado. Destaca-se a potência da prática artística em operar nas lacunas dos arquivos hegemônicos para amplificar histórias consideradas menores, relativas a lugares atingidos por operações físicas e simbólicas de obliteração.
O CHAMADO: OLHARES SOBRE CAIS DAS ARTES
Authors: Izoton Braga Leonardo
Published: September 2023

Este ensaio é construído a partir de um chamado da cidade no contexto pandêmico, disparando uma deriva de olhares para um corpo arquitetônico: O Cais das Artes. Tem como objetivo a apreensão, circulação e a crítica das imagens do Cais, reintegrando-o ao imaginário urbano e público. O texto divide-se em um prólogo e cinco sessões. Sua montagem é composta e tensionada por fotografias, na tentativa de tramar escrita, imagem e pensamento. Almeja-se com isso explorar problemas, mas, sobretudo, as potencialidades do complexo arquitetônico, que se apresenta na tensão entre sonho e abandono, ruína vital e ruína do futuro. Deste modo, o ensaio manifesta um chamado à sua visibilização crítica, sua ocupação corpórea, a luta política pelo seu término e sua entrega enquanto complexo cultural e espaço público.
ERA UMA VEZ UMA CERCA...

Published: September 2023

Abandonos urbanos são, muitas vezes, sutilmente delimitados e de difícil percepção, quer do céu, quer do chão. É sobre um desses abandonos que esse ensaio se debruça: o território de uma comunidade carente e periférica, onde uma ordem de cercamento de um remanescente de mata desencadeia reflexões sobre descasos ambientais e físico-sociais. Insubordinando-se a essa ordem, buscou-se inventar com essa comunidade modos outros de cercar, física e simbolicamente mais inclusivos. Apoiada principalmente no conceito de Terceira Paisagem e nas próprias reflexões e práticas dessa comunidade, a cerca-outra que emerge ganha espessura. Com contornos físicos e virtuais imprecisos, ela ensaia ser uma cerca ecológica, produtiva, pedagógica e autoconstruída, ressignificando assim ideias de limite e, consequentemente, abandonos de diversas ordens por elas impostos. A cerca emergente é uma utopia política, aberta a incertezas da vida e aos sonhos por vir.
