Effect of Benzyl Amino Purine (BAP) on the Leaf Growth of Vanda limbata Blume Orchid In Vivo
Authors: Az Zahra Sischa Aulia Putri , Setiari Nintya , Nurchayati Yulita 
Published: March 2024

<p><em>Vanda limbata</em> is a natural orchid with slow growth and is often taken directly from the forest in large quantities, threatening its sustainability. Ex-situ preservation efforts are needed for this orchid, one of which is through cultivation with the addition of Benzyl Amino Purin (BAP), known to increase shoot growth. This research aims to analyze the effect of BAP and determine its optimal concentration on the growth of <em>V. limbata</em> orchids. This research used a single-factor completely randomized design in BAP concentrations of 0, 25 and 50 mg l<sup>-1</sup> with 5 replications. The method used was spraying BAP solution once a week on all parts of adult <em>V. limbata</em> orchids aged ±2 years. The research was conducted for 3 months in the experimental garden with parameters observed in the form of the number of new leaves, elongation of old leaves, the length of new leaves, increase in the width of old leaves, the width of new leaves, stomatal density and the number of roots. The results showed that the most effective BAP concentration was 50 mg l<sup>-1</sup> for the number of new leaves which increased by 200%, the length of old leaves which increased by 168.66% and the length of new leaves which increased by 800%, but resulted in less stomatal density than the control. BAP can increase the growth of <em>V. limbata</em> orchid leaves. This research can be a recommendation for ex-situ conservation efforts that have the potential to be developed as a means of orchid cultivation.</p>
Different measures, different perceptions: A survey on measure sensitivity of inequality perception from Japan

Published: April 2024

Abstract

Understanding whether our perceptions of the world are influenced by the way in which statistics are presented is a critical issue for public policy discussions because policy debates are often based on our perceptions of the world through our interpretations of data, as in the case of issues pertaining to income inequality. In this study, we investigate the sensitivity of perceived inequality to different stratification measures. We randomly presented 15,000 Japanese adult respondents with either the stratification index proposed by Xiang Zhou or a series of household income percentiles, both of which were derived from the same data distribution spanning two periods in Japan. Our findings indicate that respondents perceived a more significant increase in inequality when they were presented with the income percentiles than when they were presented with Zhou's stratification index. Therefore, to ensure consistency in public policy making, we must observe not only the same fact but also the same measurement of that fact. Different measurements of one fact may lead to different perceived worlds in our minds.

Published: April 2024

Abstract
Background: Abnormal autophagy and TGFβ-SMAD3/7 signaling pathway plays an important role in intrauterine adhesions (IUA); however, the exact underlying mechanisms remain unclear. In this study, we aimed to detect whether SMAD7 effected IUA via regulating autophagy and TGFβ-SMAD3 signaling pathway.
Methods: The expression of p-SMAD3 and SMAD7 were detected by Immunohistochemistry. Endometrial fibrosis was detected by masson staining. The expression of protein related autophagy and fibrosis was detected by western blot. The autophagic flux was monitored via Tandem mRFP-GFP-LC3 fluorescence system. Chip assay was used for SMAD3 binding site analysis. SMAD7 knockout mice were used for investigated the regulation of SMAD7 on intrauterine adhesions and autophagy.
Results: we observed that patients with IUA exhibited a high expression of p-SMAD3 in the endometrium whereas SMAD7 expression decreased. In endometrial stromal cells, the silencing of SMAD7 inhibits autophagic flux, whereas overexpressed SMAD7 promotes autophagic flux. We also found that SMAD7-mediated autophagic flux regulated stromal-myofibroblast transition. These phenotypes are regulated by the transforming growth factor (TGF)β-SMAD3 signaling pathway. We found that SMAD3 directly binds to the 3ʹ-untranslated region of transcription factor EB (TFEB) and inhibits its transcription. SMAD7 promotes autophagic flux by inhibiting SMAD3, thereby suppressing the inhibition of TFEB. The endometria of SMAD7 knockout mice showed a fibrotic phenotype. Simultaneously, autophagic flux was inhibited. On administering the autophagy activator rapamycin, endometrial fibrosis of SMAD7 gene conditional knockout mice was partially restored.
Conclusions: the loss of SMAD7 promotes endometrial fibrosis by inhibiting autophagic flux via the TGFβ-SMAD3 pathway. Therefore, this study reveals a potential therapeutic target for IUA.

Abstract

Lumpy skin disease (LSD) is a re-emerging transboundary viral disease of cattle and buffaloes with severe economic impact and is listed as a notifiable disease by the World Organization for Animal Health. Mass vaccination of susceptible animals is the foremost approach in tackling this infectious disease. Although the efficacy and immunogenicity of homologous LSD vaccine (Lumpi-ProVacInd) is known to be excellent, cost of vaccine production along with the neethling responses observed in the vaccinated animals and limited availability for the field use during the current outbreak are the major limitations. Live attenuated Goatpox vaccine of Uttarkashi strain is authorized by the government for control of LSD as an emergency measure in India during 2022. The present study deals with an objective to determine the optimum dose of Goatpox vaccine against LSD infection in cattle. Vaccination trial was conducted in randomly selected heifers placed into four groups (A, B, C and D) of eight animals each. Group A served as control group, while groups B, C and D were vaccinated with 1mL, 2mL and 3mL of 1 X 103.0 TCID50/dose of Goatpox vaccine respectively. Group D vaccinated with 3 times the dose used in goats produced the best humoral immunity and the responses persisted till the end of the trail i.e., 35 days post vaccination (p > 0.05).

Abstract

Incidental capture of non-target species poses a pervasive threat to many marine species, with sometimes devastating consequences for both fisheries and conservation efforts. Because of the well-known importance of vocalizations in cetaceans, acoustic deterrents have been extensively used for these species. In contrast, acoustic communication for sea turtles has been considered negligible, and this question has been largely unexplored. Addressing this challenge therefore requires a comprehensive understanding of sea turtles’ responses to sensory signals. In this study, we scrutinized the avenue of auditory cues, specifically the natural sounds produced by green turtles (Chelonia mydas) in Martinique, as a potential tool to reduce bycatch. We recorded 10 sounds produced by green turtles and identified those that appear to correspond to alerts, flight or social contact between individuals. Subsequently, these turtle sounds—as well synthetic and natural (earthquake) sounds—were presented to turtles in known foraging areas to assess the behavioral response of green turtles to these sounds. Our data highlighted that the playback of sounds produced by sea turtles was associated with alert or increased the vigilance of individuals. This therefore suggests novel opportunities for using sea turtle sounds to deter them from fishing gear or other potentially harmful areas, and highlights the potential of our research to improve sea turtles populations’ conservation.

Published: April 2024

Abstract

Background:Technologies such as interactive robotics and motion capture systems permit the development of kinematic-based approaches to assess motor impairments in stroke survivors. Here we utilise the Kinarm Exoskeleton robotic system and deep learning techniques to explore differences in motor performance between healthy controls, individuals with stroke and transient ischemic attacks (TIA).Methods:Building upon previous research that employed deep learning methods to distinguish between minimally impaired stroke patients and healthy controls using Kinarm data, this study introduces a novel dimension by estimating the confidence or uncertainty of the model's predictions. An evidential network is employed to measure this confidence, which subsequently aids in the refinement of training and testing datasets.Results:The application of deep learning techniques in this context proves to be promising. By utilizing uncertainty measures to systematically enhance datasets, the sensitivity and specificity of detecting stroke-related impairments are improved. Furthermore, this model is extended to address the detection of potential impairments in individuals following TIA, where traditional methods often fall short. The hypothesis that the deep learning model has the capacity to detect impairment is tested, with initial results indicating its potential in identifying impairments in individuals with TIA based on subtle but measurable motor deficits.Conclusions:This comprehensive investigation highlights the value of deep learning in the assessment of neurological conditions using Kinarm. The introduced uncertainty estimation offers a nuanced approach to data refinement, enhancing the clinical utility of stroke detection and expanding to identification of potential impairments following TIA.
