Taxonomic Characterization of Two New Diatoms Podosphenia bangladeshika sp. nov. and Synedra ulna var. cladophorae var. nov. (Bacillariophyceae) from Bangladesh Water
Authors: Bhuiyan M A H , Kowser A , Islam S A M S , Khondker M
Published: July 2024

The algal class Bacillariophyceae (diatom) of Bangladesh is represented by nearly 291 species with almost no recent reporting of new species and/or variety. This research paper describes one new species of marine diatom Podosphenia and a variety of freshwater diatom Synedra species. The former was collected from the Bay of Bengal, Bangladesh and the latter was from Hail Haor, Srimangal, Moulvi Bazar, Bangladesh. The marine species is from genus Podosphenia Ehr. The species novo has been proposed as Podosphenia bangladeshika. A freshwater periphytic diatom from the Hail Haor wetland, Srimangal, Moulvi Bazar was initially identified as Synedra ulna due to the shape of the branched filamentous colony. The shape of the colony was quite different and looked like a twig of a green branched filamentous alga Cladophora. The species is hitherto proposed as a new variety Synedra ulna var. cladophorae.

Published: July 2024

Direct and indirect in vitro organogenesis of Alocasia baginda 'Silver Dragon' was investigated using explants of shoot tips, leaf tissue, and petiole segments. For direct shoot induction from shoot tips, MS medium containing 1.5 mg/l BAP was shown to be the most efficient (80%), producing a maximum of 6.60 ± 0.93 shoots/explant with 3.66 ± 0.38 cm in length. Directly induced shoots were multiplied using a 2.5 mg/l BAP enriched medium, where the number and length of shoots/culture were 11.60 ± 1.12 and 9.20 ± 1.01 cm, respectively. Shoots gradually increased in number and length during the 1st three sub-culture cycles in the similar medium combination but declined after 3rd cycle. Following the 3rd sub-culture cycle, there were 14.80 ± 0.58 shoots per culture, with a shoot length of 9.90 ± 0.63 cm. The greatest frequency of callus induction was 97.67% for leaf tissue and 86.67% for petiole segments when they were cultured on the media containing 3.0 mg/l 2,4-D. Impressive results regarding indirect shoot organogenesis (90%) with maximum shoot number/unit callus (16.20 ± 1.62) and shoot length (11.06 ± 0.97 cm) were noted upon transferring the callus onto MS medium containing 3.5 mg/l BAP and 3% sucrose. Within 10-12 days, 100% rooting was observed in half-strength of gelled MS medium containing 2.0 mg/l IBA, with an average of 15.40 ± 1.17 roots/culture. After being acclimatized in a potting mixture containing garden soil, compost, coco peat, and moss in a 2:1:1:1 ratio, A. baginda 'Silver Dragon' exhibited a 100% survival rate. Established plantlets seem morphologically similar to mother plants and possess fully developed root and shoot systems, along with an adequate leaf number per plant.

Published: July 2024

Turmeric  (Curcuma longa) is used as a spice and has excellent medicinal value. However, the field multiplication rate of turmeric plants is not satisfactory. In vitro methods could be a feasible alternative to vegetative propagation in the field. This study was aimed at developing a suitable protocol for the clonal propagation of turmeric confirming the genetic fidelity of the in vitro regenerated plantlets. The explants of shoot bud (full, half, and quarter), root, rhizome, and leaf were cultivated on MS medium with BAP, NAA, and Kinetin. Cultured shoot buds showed a higher regeneration frequency and shoots per explant than those obtained from other explants. The highest shoot regeneration was 72.49% from shoot buds, followed by rhizome (68.76%) and the lowest was 53.93 % from ¼ shoot buds. There were significant effects of growth regulator combinations and concentrations in shoot regeneration from shoot bud explant. The highest shoot regeneration per shoot bud explant was 4.42 with BAP at 20.0 mg/l and NAA at 0.5 mg/l at 24 weeks. The best rooting response with 9.75 roots per explant was reported with 1.0 mg/l BAP with 1.0 mg/l NAA. The rooted plants were successfully transferred to pots for their acclimatization. Both the micropropagated shoots and their mother plant produced monomorphic bands with the six RAPD markers that confirm the genetic fidelity of micropropagated clones. These results showed that in vitro raised plantlets of turmeric had no risk of somaclonal variations and were found to be true-to-type in nature over the culture period. The protocol developed through this investigation has the potential application for the rapid multiplication of turmeric plants.

Treating Infertility without Assisted Reproduction Techniques
Authors: Check Jerome H , Neumann Brooke , Karnish Ava Therese
Published: July 2024

Reproductive Endocrinology/Infertility, programs today emphasize in vitro fertilization-embryo transfer (IVF-ET), intracytoplasmic sperm injection, and pre-implantation genetic diagnosis. When the infertility specialist begins his/ her career, unfortunately, most are not trained to solve infertility problems by non-expensive means without assisted reproductive technology. Thus, today it becomes more important for the generalist in obstetrics and gynecology to learn the principles of treating infertility using methods that are best suited for most patients which are methods generally reimbursed by third party insurance carriers that will not financially deplete the patients. Unfortunately, during OB-GYN residency the teaching of methods for treating infertility is by rotation through REI practices where the emphasis is on IVF-ET. This review is written for the purpose of providing a basis for those OB-GYN physicians who want to know more about diagnosis and treating infertility, to help their patients conceive without expensive procedures e.g., IVF-ET. The “expert” opinion is not only based on 50 years of extensive clinical experience but will provide the published research studies by the authors that provide at least a good starting point for learning methods of treating infertility. Nevertheless, these suggestions need to be modified by the OB-GYN generalist to conform to their patient population, their findings based on their own experience, and based on the nature of their own practice to determine how much time can be dedicated to treat infertility problems themselves.
A Study to Determine the Impact of Diminished Oocyte Reserve (DOR) on Pregnancy Outcome in Women of Advanced Reproductive Age
Authors: Brooke Neumann , Jerome Check , Micheal Sobel , Kathy Hollahan , Carrie Wilson
Published: July 2024

Background: Both advancing age and diminished oocyte reserve (DOR) have a negative impact on fecundity. Objective: To determine what effect diminished oocyte reserve (DOR), as determined by low anti-Mullerian hormone levels, has on live delivered pregnancy rates following in vitro fertilization embryo transfer (IVF-ET) in women aged-40-42. Design: This was a retrospective study. Materials and Methods: A retrospective study was performed in women aged 40-42 undergoing IVF-ET with DOR or normal ovarian reserve (NOR). The women were divided into two groups based on egg reserve: DOR (anti-mullerian hormone (AMH) level <1 ng/ml) and normal oocyte reserve (NOR) (serum AMH ≥ 1ng/ml). A type of mild ovarian stimulation protocol, known as the FSH receptor up-regulation technique, was used for women with DOR. Setting: University-associated private practice IVF center. Results: The live delivered pregnancy rate (LDPR) was 12.6% for the DOR group and 12.9% for normal oocyte reserve (NOR). Conclusion: Since the LDPRs were the same for women aged 40-42 with DOR compared to NOR, a low serum AMH should not be a deterrent for performing IVF-ET in women aged 40-42. If this LDPR is not acceptable, then one could consider the use of donor eggs.

Thermal protection systems (TPS) are employed on space vehicles to protect against the heat fluxes faced upon re-entry to the Earth’s atmosphere. This work reports a method of 3D printing composite materials for TPS to reduce the time and cost associated with hand layup production methods. A phenolic resin system was tested to determine char yield, viscosity, cure behavior and cure evolutions. A commercial 3D printer was modified to move along two additional axes to accommodate the complex curves of typical heat shields on space vehicles. This technique can be scaled to produce full-sized TPS for industrial applications.

Published: July 2024

Рассматриваются вопросы рационального использования и охраны земель прибрежных территорий речных бассейнов с целью их защиты от отрицательного воздействия вод, что непосредственно направлено на улучшение организации территорий. Масштаб проблемы негативного воздействия вод показан на примере территорий Дальнего Востока. Для этих территорий только для сельского хозяйства ущерб от воздействия вод оценивается на уровне 10 млрд руб. Оценена эффективность защиты земель, подверженных затоплению, на примере с. Ленинское Еврейской автономной области, расположенной на левобережной пойме р. Амур и имеющей значительную площадь водосбора. В качестве наиболее вероятной и тяжелой аварии рассмотрен сценарий в меженный период и при прохождении высокого паводка. Показано, что строительство новых и реконструкция существующих защитных гидротехнических сооружений обеспечивает эффективное снижение негативного влияния затоплений на окружающие земли, в том числе земли населенных пунктов и земли сельскохозяйственного назначения. При этом показатель предотвращаемого ущерба, выраженный в денежной форме возможных негативных последствий, может быть принят в качестве оценки экономической эффективности строительства (реконструкции) гидротехнических сооружений для снижения риска и смягчения негативного влияния затоплений прибрежных территорий и осуществления мероприятий для охраны земель.

На Семипалатинском испытательном ядерном полигоне (СИЯП) проводились испытания ядерных зарядов в различных средах: в воздухе, над землей и под землей в скважинах и штольнях. После взрывов наблюдалось проседание и выпучивание поверхности соответственно от –0,4 до +3,9 м, а иногда имели место ее провалы до –21,0 м. Это приводило к образованию трещин, из которых выходил газ, содержащий техногенные радионуклиды, вследствие которого происходило загрязнение тяжелыми металлами прилегающих территорий. В связи с передачей территории в хозяйственное использование важно проводить деформационный мониторинг уровня загрязнения как на полигоне, так и на прилегающей территории. В настоящее время этот мониторинг производится для отдельных скважин высокоточным геометрическим нивелированием II класса. В связи с этим возникла научно-техническая задача разработки схемы построения геодинамического полигона, а также методики ведения деформационного мониторинга на всю территорию расположения испытательных скважин с соблюдением требования – минимального влияния радионуклидного загрязнения на исполнителей. Для решения данной задачи, в зависимости от фактического уровня загрязнения, предлагается схема построения геодинамического полигона, а также методика выполнения инженерно-геодезических измерений на нем с применением спутниковых технологий, полигонометрии, геометрического и тригонометрического нивелирования. Для ведения деформационного мониторинга территории расположения испытательных скважин выполнен предрасчет точности определения высотного положения пунктов сети, который показывает, что величина средней квадратической ошибки (СКО) определения их положения на всей территории испытательной площадки геометрическим и тригонометрическим нивелированием III класса не превышает 4,5 мм.

Situada no bairro Seminário em Curitiba, a obra “Fonte de Jerusalém” da artista curitibana Lys Áurea Buzzi trata-se de um trio de esculturas aladas sobre um pedestal em concreto armado instaladas no ano de 1995. Tal complexo escultórico foi realizado sob encomenda do então Prefeito da capital paranaense Rafael Valdomiro Greca de Macedo, durante sua primeira gestão (1993-1996). De acordo com as fontes, alterações no âmbito estrutural e temático foram realizadas de maneira compulsória pela gestão municipal em desacordo com as intenções primárias da encomenda. Desta maneira, este artigo pretende identificar e interpretar o oportunismo narrativo experimentado pelas “anjas” de Buzzi. Como uma forma de contextualizar a postura de Greca, o texto aponta alguns aspectos da história urbanística da cidade a partir dos escritos de Dennison de Oliveira (2000). Ademais, para aprofundar as problematizações relativas à memória, o artigo foi fundamentado no texto de Andreas Huyssen (2014). Quanto às fontes textuais, o levantamento foi realizado em sites locais e institucionais, bem como em redes sociais. Em resumo, o artigo interpreta a imposição plástica e temática sobre o que era pra ser chamado de “Memorial às Américas”.
Formação social brasileira e luta de classes no cinema de ficção científica
Authors: Finkler Lachowski Victor
Published: July 2024

Esta pesquisa realiza uma investigação de como a formação social brasileira e sua luta de classes estão presentes nas obras “Branco Sai, Preto Fica” (2015) e “Bacurau” (2019). Para compreender essa formação social brasileira e sua luta de classes é utilizado o aporte teórico de abordagem materialista histórico-dialética. Para estudar a tendência operativa de FC, pesquisa-se a lógica histórica do surgimento e desenvolvimento do FC brasileiro. Com as análises, percebe-se em “Branco Sai, Preto Fica” (2015) a periferização da população preta em grandes centros urbanos como algo sintomático da formação social brasileira, além de explicitar o papel das forças coercitivas do Estado, como a polícia, em oprimir as classes exploradas/racializadas; A reação a essa opressão no filme é uma conspiração cuja força-motriz é a cultura popular das populações marginalizadas para a criação de uma bomba que explode Brasília e a Ditadura Militar que governa o país no universo da obra. Em “Bacurau” (2019) os moradores locais tem que lutar pela sobrevivência contra estrangeiros que representam essa ameaça alienígena de perspectiva colonial/imperialista, e contra as instituições do Estado burguês brasileiro, como políticos e empresários, que auxiliam na opressão autóctone particular que volta para a universalidade da formação social brasileira, bem como nessa metáfora/analogia para a o desenvolvimento histórico brasileiro pautado na exploração do estrangeiro e da manutenção da escravidão.

Introduction

Vertebrate sensory systems are in close contact with surrounding tissues, often leaving bony signatures behind. These bony features are the keys to assessing variation in sensory systems in fossil taxa. The trigeminal sensory system (e.g., trigeminal ganglion, ophthalmic, maxillary, and mandibular divisions) has osteological correlates throughout the skull, including the braincase (e.g., trigeminal fossa, prootic notch, ophthalmic and maxillomandibular foramina) and rostrum (e.g., mandibular canal, neurovascular foramina).

Methods

Here we measured and compared these features among a morphologically, phylogenetically, and ecologically diverse sample of sauropsids to determine strength of osteological correlates and to explore ecomorphological trends. We determined several suitable osteological correlates for trigeminal soft tissue features and discounted foramen count alone as a suitable osteological correlate. However, when size was accounted for, foramen count becomes a useful indicator of sensory ecology.

Results and discussion

Among extant taxa, those engaging in tactile sensory behaviors with the face exhibit relatively larger trigeminal tissues and osteological correlates than those not engaging in tactile sensory behaviors. Though patterns are unclear among several clades, both relative feature sizes and models used to predict sensory capacity reveal a trend of increasing tactile sensitivity along the pseudosuchian lineage. Overall, a quantitative assessment of ecomorphological trends of trigeminal osteological correlates proves informative for the hypotheses of sensory behavior in extinct taxa and supports the use of similar assessment methods for other osteological correlates.

Introduction: The formation of bacterial biofilms on knee arthroplasty implants can have catastrophic consequences. The aim of this study was to analyze the effectiveness of the bioelectric effect in the elimination of bacterial biofilms on cultivated knee arthroplasty implants.

Methods: A novel device was designed to deliver a bioelectric effect on the surface of knee arthroplasty implants. 4-femoral prosthetic implants were cultivated with a staphylococcus aureus inoculum for 15 days. The components were divided into four different groups: A (not treated), B (normal saline 20-minutes), C (bioelectric effect 10-minutes), D (bioelectric effect 20-minutes). The implants were sonicated, and the detached colonies were quantified as the number of colony-forming unit (CFUs). The implants were sterilised and the process was repeated in a standardized manner four more times, to obtain a total of five samples per group.

Results: The number of the CFUs after a 10-minute exposure to the bioelectric effect was of 208.2 ± 240.4, compared with 6,041.6 ± 2010.7 CFUs in group A, representing a decrease of 96.5% ± 4.3 (p = 0.004). And a diminution of 91.8% ± 7.9 compared with 2,051.0 ± 1,364.0 CFUs in group B (p = 0.109). The number of bacterial colonies after a 20-minute exposure to the bioelectric effect was 70 ± 126.7 CFUs, representing a decrease of 98.9% ± 1.9 (p = 0.000) compared with group A. And a decrease of 97.8% ± 3.0 (p = 0.019) compared with group B.

Conclusions: The bioelectric effect was effective in the elimination of bacterial biofilm from knee arthroplasty implants. This method could be used in the future as part of conventional surgical procedures.
Case Report: Persistent residual shunt after a first percutaneous PFO closure followed by minimally invasive surgical failure: third time is a charm

Published: July 2024

Background

Even though the optimal management of a moderate or large residual shunt following patent foramen ovale (PFO) closure is open to question, recent data confirmed that it is associated with an increased risk of stroke recurrence.

Case summary

A 48-year-old woman, a migraineur with visual aura, was diagnosed with a PFO associated with a huge multifenestrated atrial septal aneurysm (mfASA) and a moderate right-to-left shunt, detectable only after a Valsalva maneuver on contrast-transthoracic echocardiography. Brain magnetic resonance imaging showed a 1-mm silent white matter lesion in the right frontal lobe. Although the indication was not supported by guidelines, a transcatheter PFO closure was performed at another center with implantation of a large, equally sized, double-disc device (Figulla UNI 33/33 mm). At 6-month follow-up, a 2D/3D transesophageal echocardiography (TEE) color Doppler showed incorrect orientation of the device, which was not parallel to the interatrial septum, with two discs failing to capture the aortic muscular rim and partially protruding in the right atrium; furthermore, a 4 mm × 7 mm ASA fenestration was documented with a residual bidirectional shunt. Thereafter, the same team performed a minimally invasive cardiac surgery under femoro-femoral cardiopulmonary bypass; however, the procedure proved ineffective and was complicated by postoperative pericarditis with pericardial effusion, requiring further rehospitalization 1 month later due to persistent pericarditis, bilateral pleuritis, phrenic nerve palsy, and atrial flutter, which was treated with amiodarone. The patient asked for a second opinion, and our multidisciplinary heart team decided to offer a percutaneous redo intervention. An uneventful implantation of a regular PFO occluder (Figulla Flex II 16/18 mm) across the septal defect was performed successfully. Twelve-month follow-up with 2D TTE color Doppler and contrast transcranial Doppler showed correct position and good interaction between the two devices, with no residual shunt.

Discussion

In addition to the incorrect indication for PFO closure and the failure of minimally invasive surgery, the procedural mishap in this case could have been due to the inappropriate implantation of the first large device within the tunnel. It would have been better to deploy the same large device in the most central fenestration, covering the PFO and a greater part of the remaining mfASA at the same time.

Objects

The aim of this study was to investigate the morphologic changes of a novel fully biodegradable implantable device after closing a perimembranous ventricular septal defect (Pm-VSD) and to evaluate the effect of the occluder on the myocardial function in patients during a 3-year follow-up period.

Methods

One-year, 2-year, and 3-year follow-ups were carried out after implantation with a total of 30 Pm-VSD patients who had successful closure by the fully biodegradable occluder. In total, 30 healthy children were enrolled as controls. At discharge and at every follow-up visit, the lengths of the left and right discs of the novel device were measured in the apical three- and four-chamber as well as short-axis views. At the end of the follow-up, using three-dimensional speckle-tracking conditions, the values of myocardial deformation, including global longitudinal strain, global circumferential strain, and global area strain, were acquired.

Results

The fully bioabsorbable double-disc occluder gradually decreased over time and was eventually invisible under echocardiographic scanning during the follow-up (p < 0.05). At the end of the third year, there were no significant differences in the myocardial deformation parameters between the cases implanted with the novel devices and the controls; no significant differences were found between the basal segments of the ventricle septa and that of the left ventricle (LV) free wall among the patients who completed the Pm-VSD closure using the fully biodegradable occluder (p > 0.05).

Conclusion

The novel fully biodegradable occluder is a safe, effective, and perfect alternative for the treatment of VSD. Echocardiography plays a crucial role in the follow-up of this new type of occluder implantation.

Obesity is a chronic disease, and while weight loss is achievable, long-term weight loss maintenance is difficult and relapse common for people living with obesity. Aiming to meet the need for innovative approaches, digital behavior change interventions show promise in supporting health behavior change to maintain weight after initial weight loss. Implementation of such interventions should however be part of the design and development processes from project initiation to facilitate uptake and impact. Based on the development and implementation process of eCHANGE, an evidence-informed application-based self-management intervention for weight loss maintenance, this manuscript provides suggestions and guidance into; (1) How a service design approach can be used from initiation to implementation of digital interventions, and (2) How a technology transfer process can accelerate implementation of research-based innovation from idea to market.
