Authors: Laltlanmawia C. , Saha Himadri , Ghosh Lija , Saha Ratan Kumar , Malla Supratim
Published: August 2023

Background: This study presents the successful isolation and comprehensive characterization of a selected virulent strain of Aeromonas hydrophila, denoted COF_AHE51, which was identified as the causative agent behind mass fish mortality in an aquaculture pond in Tripura. Methods: The identification of this species was achieved through morphological, biochemical, and molecular techniques. The pathogenicity was assessed by fulfilling Koch’s postulate, determination of haemato-biochemical and immune-pathophysiological parameters and histopathological study. The antimicrobial resistance was examined by performing antibiotic sensitivity test. Result: Experimental infection of Labeo rohita with COF_AHE51 resulted in the development of hallmark clinical signs, such as haemorrhages, abdominal swelling, discoloration and tail and fin rot. The calculated LD50 of the pathogenic strain was 1.4x106 cfu/fish. In-depth hematological and immunological analyses, alongside histopathological examinations of affected tissues, revealed remarkable perturbations suggestive of systemic bacterial septicaemia. Furthermore, the strain was observed to be resistant to several commonly used antibiotics, including kanamycin, cefoxitin, cefotaxime, and ampicillin, accentuating the considerable threat posed by A. hydrophila infections in aquaculture settings.

Published: August 2023

Background: This study was aimed to investigate the hepatoprotective effect of RSV against oxidative stress damage which we induced an experimental liver Ischemia-reperfusion (I/R) model in rats. Methods: Female albino rats were divided into three groups (n = 8). Contrast to the control group, 1 ml saline (0.09 % NaCl) was administered intraperitoneally two days before the operation and after reperfusion in the sham group. 1 ml of 50 mg/kg Resveratrol was administered to the treatment group until two days before the operation. In addition, a single dose of 1 ml of Resveratrol was re-administered after reperfusion. The duration of liver ischemia/reperfusion was determined as 30 minutes in all groups. At the end of this experiment, antioxidant enzyme (CAT, SOD) activities and the levels of malondialdehyde (MDA) were measured as spectrophotometric in liver tissues homogenates. Result: Our study, tissue injuries were observed in the ischemia/reperfusion and Sham groups (p less than 0.001). In this study, significant decreases were observed in tissue MDA levels in the treatment group compared to the sham and control groups (p less than 0.001). In addition, antioxidant enzyme levels (SOD. CAT) were significantly increased in the treatment group compared to the control and Sham groups. Liver tissue samples were examined for hepatocyte damage and histopathological grade of the groups were shown. In our study, tissue injuries were observed in the ischemia/reperfusion and Sham groups (p less than 0.001). Liver edema, necrosis and PMNL infiltration were found to be decreased in the treatment group compared to the control group. The association of resveratrol with oxidative damage was also determined by network pharmacology analysis.

The aim of the study is to determine the correlation between attitudes of Turkish nursing students toward gender roles and their perceptions of caring behaviors. The study was conducted based on cross-sectional, descriptive and relational design. First- and fourth-year nursing undergraduate students studying at four state universities located in a large city in Türkiye were included in the study (n=541). Three forms including “Descriptive Characteristics Form”, “The Gender Roles Attitude Scale” and “Caring Assessment Questionnaire” were used as data collection tools. The students' GRAS mean score was 147.12±15.47 and the highest subscale mean was detected in the egalitarian gender role subscale. The students' Care-Q total mean score was 4.99±1.34 and the highest subscale mean was observed in the “Monitors and Follows Through” subscale. As a result of the study, it was observed that there was a statistically significant positive and very weak correlation between the nursing students' caring behaviors and attitudes toward gender roles. The results indicated that the students participating in the study had an egalitarian attitude and as the egalitarian attitude increased, their caring assessment behaviors also increased.

Camellia sinensis L. is a small tree in the Theaceae family. From its leaves is produced a tea, which is the second most consumed non-alcoholic beverage in the world. The tea of this plant can bring several health benefits, however, some elements present in the leaves of Camellia sinensis L. are potentially toxic, for example, As, Cd and Pb; since they are among the ten chemical substances of major health risks. Thus, the objective of this work was to determine the concentrations of As, Cd, Cr, Cu, Pb and Zn by inductively coupled plasma optical emission spectrometry (ICP OES) after acid digestion of commercial samples of black tea from the plant Camellia sinensis L. acquired in supermarkets from Campos dos Goytacazes (Brazil). The detection limits for the elements were 0.5 mg kg−1 for As; 0.003 mg kg−1 for Cd; 0.02 mg kg−1 for Cr; 1.2 mg kg−1 for Cu; 0.09 mg kg−1 for Pb and 0.04 mg kg−1 for Zn. The concentrations found of the potentially toxic elements Cd and Pb in the black teas of Camellia sinensis L. are below the concentrations established by ANVISA (0.60 mg kg−1 and 0.40 mg kg−1, respectively).

Published: August 2023

BACKGROUND:Previous studies have demonstrated that people with Parkinson's disease (PD) can acquire postural control skills even with the degeneration of motor areas responsible for consolidation of the representation regarding the learned motor skill in long-term memory. However, these findings have not considered the PD motor subtypes – tremor-dominant (TD), and postural instability and gait difficulty (PIGD). Although there is considerable heterogeneity in motor and non-motor symptoms between TD and PIGD, no study has addressed the effect of the PD subtype on learning postural control skills.
AIM:We investigated the influence of PD motor subtypes on the learning of tasks with different postural control demands.
METHOD:Fourteen individuals with PD (7 TD, 7 PIGD) practiced four motor tasks with high postural and cognitive demands. Participants completed 13 one-hour sessions (2x/week for 7 weeks). We considered the first and last practice sessions, pre-test and post-test, respectively. Also, we conducted one-week and one-month retention tests to assess performance persistence (motor learning). We assessed motor performance through the scores achieved on each motor task.
RESULTS:Both groups demonstrated improvement in performance during the acquisition phase. However, the TD group outperformed the PIGD group in all motor tasks, despite both groups showing improvement in motor performance when comparing the results of pre-test with the post-test, and the improved performance was maintained in retention tests. The performance differences between groups are dissipated during consolidation, and they did not directly affect motor learning.
INTERPRETATION: The TD and PIGD motor subtypes learned postural control tasks with different motor and cognitive demands.

Published: August 2023

Highlights

Jackfruit leaf extraction was performed by percolation method using 96% ethanol solvent with flavonoid, saponin, tannin, alkaloid, and steroid terpenoid test.
Jackfruit leaf extract was effective as a larvicide against larvae of Aedes aegypti.

Abstract
Background: Dengue Hemorrhagic Fever (DHF) is a disease caused by the dengue virus, which enters the human bloodstream through the bite of a mosquito of the Aedes genus. The DHF control program is carried out by breaking the vector chain, the Aedes aegypti larvae. The underutilized jackfruit (Artocarpus heterophyllus L.) leaves contain secondary metabolites that have the potential to be larvicides. Secondary metabolites that have the potential as larvicides are flavonoids, saponins, tannins, alkaloids, steroids, and terpenoids. Objective: This study was to determine the effectiveness of jackfruit leaf extract as a larvicide in controlling Aedes aegypti vectors and to determine the most effective concentration of jackfruit leaf extract as an Aedes aegypti larvicide. Material and Method: The study was an analytic observational study using a cross-sectional design. The study was conducted from March 2022 to April 2022. Jackfruit leaf extraction was performed by percolation method using 96% ethanol solvent with flavonoid, saponin, tannin, alkaloid, and steroid terpenoid test. The data were analyzed with SPSS Anova (parametric) and Kruskal Wallis non-parametric. Result: In the extraction of 243 gr jackfruit leaves using the percolation method, the yield was 24.3%. Jackfruit leaf extract was effective as a larvicide against Aedes aegypti larvae, even at a concentration of 0.75%. The LC50 results for the total concentration obtained were 0.331% with strong toxicity (poisonous). Jackfruit leaf extract at a concentration of 2% yielded mortality value of 91.2 at 8 hours and at a concentration of 3% it yielded mortality value of 96 at 8 hours. Conclusion: Jackfruit leaf extract was effective as a larvicide against Aedes aegypti mosquito larvae.
A comprehensive overview of recent developments on the mechanisms and pathways of ferroptosis in cancer: the potential implications for therapeutic strategies in ovarian cancer
Authors: Kobayashi Hiroshi , Yoshimoto Chiharu , Matsubara Sho , Shigetomi Hiroshi , Imanaka Shogo
Published: August 2023

Cancer cells adapt to environmental changes and alter their metabolic pathways to promote survival and proliferation. Metabolic reprogramming not only allows tumor cells to maintain a reduction-oxidation balance by rewiring resources for survival, but also causes nutrient addiction or metabolic vulnerability. Ferroptosis is a form of regulated cell death characterized by the iron-dependent accumulation of lipid peroxides. Excess iron in ovarian cancer amplifies free oxidative radicals and drives the Fenton reaction, thereby inducing ferroptosis. However, ovarian cancer is characterized by ferroptosis resistance. Therefore, the induction of ferroptosis is an exciting new targeted therapy for ovarian cancer. In this review, potential metabolic pathways targeting ferroptosis were summarized to promote anticancer effects, and current knowledge and future perspectives on ferroptosis for ovarian cancer therapy were discussed. Two therapeutic strategies were highlighted in this review: directly inducing the ferroptosis pathway and targeting metabolic vulnerabilities that affect ferroptosis. The overexpression of SLC7A11, a cystine/glutamate antiporter SLC7A11 (also known as xCT), is involved in the suppression of ferroptosis. xCT inhibition by ferroptosis inducers (e.g., erastin) can promote cell death when carbon as an energy source of glucose, glutamine, or fatty acids is abundant. On the contrary, xCT regulation has been reported to be highly dependent on the metabolic vulnerability. Drugs that target intrinsic metabolic vulnerabilities (e.g., GLUT1 inhibitors, PDK4 inhibitors, or glutaminase inhibitors) predispose cancer cells to death, which is triggered by decreased nicotinamide adenine dinucleotide phosphate generation or increased reactive oxygen species accumulation. Therefore, therapeutic approaches that either directly inhibit the xCT pathway or target metabolic vulnerabilities may be effective in overcoming ferroptosis resistance. Real-time monitoring of changes in metabolic pathways may aid in selecting personalized treatment modalities. Despite the rapid development of ferroptosis-inducing agents, therapeutic strategies targeting metabolic vulnerability remain in their infancy. Thus, further studies must be conducted to comprehensively understand the precise mechanism linking metabolic rewiring with ferroptosis.

In thin samples, such as membranes, kinks inside ferroelastic domain walls interact through “dipolar” interactions following a 1/d 2 decay, where d is the distance between the walls. Simultaneously, the samples relax by bending. Bending is not possible in thick samples or can be suppressed in thin films deposited on a rigid substrate. In these cases, wall-wall interactions decay as 1/d , as monopoles would do. In free-standing samples, we show a wide crossover regime between “dipolar” 1/d 2 interactions and “monopolar” 1/d interactions. The surfaces of all samples show characteristic relaxation patterns near the kink, which consists of ridges and valleys. We identify the sample bending as the relevant image force that emanates from kinks inside walls in thin samples. When samples are prevented from bending by being attached to a substrate, the dipolar force is replaced by “monopolar” forces, even in thin samples. These results are important for transmission electron microscopy imaging, where the typical sample size is in the dipolar range while it is in the monopolar range for the bulk.

Published: August 2023

This paper introduces a novel approach to addressing the challenge of accurately timing short distance runs, a critical aspect in the assessment of athletic performance. Electronic photoelectric barriers, although recognized for their dependability and accuracy, have remained largely inaccessible to non-professional athletes and smaller sport clubs due to their high costs. A comprehensive review of existing timing systems reveals that claimed accuracies beyond 30 milliseconds lack experimental validation across most available systems.To bridge this gap, a mobile, camera-based timing system is proposed, capitalizing on consumer-grade electronics and smartphones to provide an affordable and easily accessible alternative. By leveraging readily available hardware components, the construction of the proposed system is detailed, ensuring its cost-effectiveness and simplicity. Experiments involving track and field athletes demonstrate the proficiency of the proposed system in accurately timing short distance sprints. Comparative assessments against a professional photoelectric cells timing system reveal a remarkable accuracy of 62 milliseconds, firmly establishing the reliability and effectiveness of the proposed system. This finding places the camera-based approach on par with existing commercial systems, thereby offering non-professional athletes and smaller sport clubs an affordable means to achieve accurate timing.In an effort to foster further research and development, open access to the device's schematics and software is provided. This accessibility encourages collaboration and innovation in the pursuit of enhanced performance assessment tools for athletes.

Reinforcement Learning (RL) has demonstrated considerable potential in solving challenges across various domains, notably in autonomous driving. Nevertheless, implementing RL in autonomous driving comes with its own set of difficulties, such as the overestimation phenomenon, extensive learning time, and sparse reward problems. Although solutions like Hindsight Experience Replay (HER) have been proposed to alleviate these issues, the direct utilization of RL in autonomous vehicles remains constrained due to the intricate fusion of information and the possibility of system failures during the learning process. In this paper, we present a novel RL-based autonomous driving system technology that combines Obstacle Dependent Gaussian (ODG) RL, Soft Actor-Critic (SAC), and meta-learning algorithms. Our approach addresses key issues in RL, including the overestimation phenomenon and sparse reward problems, by incorporating prior knowledge derived from the ODG algorithm. We evaluated our proposed algorithm on official F1 circuits, using high-fidelity racing simulations with complex dynamics. The results demonstrate exceptional performance, with our method achieving up to 89% faster learning speed compared to existing algorithms in these environments.

Abstract
An estimated 6% of the world population has serious mental illness, with one in four families having a member with some form of psychiatric disorder, who are mostly cared for by their relatives within a family setting. Although caregiving in a home setting is reported to be associated with significant mental distress, the burden of such distress is rarely measured. The purpose of this study was to quantify the burden of care among family caregivers of relatives with serious mental disorders, as well as to explore possible association between the caregiver burden of care and a range of caregiver and Mental Health Care User (MHCU) variables in a rural district in Kwa-Zulu Natal, South Africa. The Zarit Burden Interview (ZBI) scale was used to collect data from 357 caregivers, and STATA 14 was used to analyze data. The ages of the sample ranged from 18 to 65, with a mean of 50.29, and the majority (86%) were female and unemployed (83%). The ZBI scores ranged from 8 to 85, with a mean of 41.59. The majority (91%) tested positive for caregiver burden of care, which ranged from mild to severe. Using the Pearson Chi-square test of association (p=0.05), variables that were significantly associated with the burden of care were clinically related (caregiver self-reported depression, MHCU diagnosis, recent relapse of the MHCU), socio-economic (caregiver family monthly income, MHCU disability grant status and MHCU employment status) and socio-demographic (MHCU gender and MHCU level of education). The prevalence of burden of care is high and severe, and scarcity of resources in families and communities contribute to the high burden of care in these rural communities.
Diagnosis Progress and Treatment Update of Kawasaki Disease
Authors: Kuo Ho-Chang
Published: August 2023

Since first described by Dr. Tomisaku Kawasaki in 1967, the clinical diagnosis of Kawasaki disease (KD) has remained relatively unchanged. However, studies since then have suggested that diagnoses using only that original clinical criteria may lead to underdiagnosis. In this review, updated KD diagnostic methods, diagnostic methods for “atypical” KD, diagnostic pitfalls, and other differential diagnoses are discussed. Peripheral blood eosinophil showed important in distinguishing KD from febrile children. We review herein the current literature regarding new biomarkers, scoring systems, and microRNA panels that may aid in the diagnosis of KD, the importance of eosinophil and treatment updates.
The Crystal Structure of Pb10(PO4)6O Revisited: The Evidence of Superstructure
Authors: Krivovichev Sergey V.
Published: August 2023

The crystal structure of Pb10(PO4)6O, the proposed matrix for the potential room-temperature superconductor LK-99, Pb10-xCux(PO4)6O (x = 0.9-1.0), has been reinvestigated by single-crystal X-ray diffraction using crystals prepared by Merker and Wondratschek (The crystal structure is trigonal, P, a = 9.8109(6), c = 14.8403(12) Å, V = 1237.06(15), R1 = 0.0413 using 3456 unique observed reflections. The crystal structure of Pb10(PO4)6O is a superstructure with regard to the ‘standard’ P63/m apatite structure type. The doubling of the c parameter is induced by the ordering of ‘additional’ O’ atoms within the structure channels running parallel to the c axis and centered at (00z). The O’ atoms form short bonds to the Pb1 atoms, resulting in splitting the Pb1 site into two, Pb1A and Pb1B. The structural distortions are further transmitted to the Pb phosphate framework formed by four Pb2 sites and PO4 groups. The structure data previously reported by Krivovichev and Burns (Z. Kristallogr. 2003, 218, 357-365) may either correspond to the Pb10(PO4)6Ox(OH)2-x (x ~ 0.4) member of the Pb10(PO4)6O - Pb10(PO4)6(OH)2 solid solution series, or to the high-temperature polymorph of Pb10(PO4)6O (with the phase with doubled c parameter being the low-temperature polymorph).

Scientific advancements in the food industry have resulted in the discovery of natural substances that can serve various functions in food. Essential oils, in particular, can act as food preservatives or flavoring agents due to their abundance of natural antioxidants, which possess preservative properties. In this study, the composition of Thymus vulgaris essential oil was determined using GC-MS and HS-SPME. The essential oil obtained from Thymus vulgaris L. through hydro-distillation yielded approximately 4%. GC/MS analysis of the essential oil identified 11 components, with a predominant presence of oxygenated monoterpenes (56.97%). Notably, carvacrol (37.63%) and thymol (17.35%) were present in significant amounts, accounting for 54.98% of the overall composition. The in vitro antioxidant activity of the essential oil was evaluated using three methods. The DPPH free radical scavenging test yielded an IC50 of 0.51±0.11 mg mL-1. The β-carotene/linoleic acid bleaching test resulted in an IC50 of 2.58±0.10 mg mL-1. Finally, the ABTS assay indicated relatively lower antioxidant activity compared to ascorbic acid.
Microbiota-Mediated Tumor Microenvironment: Exploring the Impact on Cancer Development
Authors: Patil Abhinandan , Singh Neha
Published: August 2023

Tumor-associated microbiota refers to the community of microorganisms found in tumors and is part of the larger tumor microenvironment (TME). The discovery of the complex relationship between these microbial populations and the growth of cancer has prompted the creation of cutting-edge tailored methods to cancer treatment. In recent years, microbiota profiling's potential as a diagnostic, prognostic, and therapeutic optimization tool has been increasingly apparent. The diagnostic and prognostic use of microbiota profiling is explored in this abstract. Microbiota profiling shows potential for early cancer detection, improved risk stratification, and greater prediction of treatment outcomes by identifying different microbial signatures associated with early-stage tumors, aggressive characteristics, and responses to treatment. In addition, this method provides the way for individualized medicinal approaches based on an individual's specific microbiome.Microbiota profiling is investigated as a means of customizing treatment plans, illuminating how knowledge of an individual's microbiome might direct the development of individualized treatments and multimodal approaches. These kind of interventions have the potential to herald in a new era of patient-centered oncology care by increasing treatment efficacy while decreasing side effects. Despite significant promise, microbiota profiling has obstacles that must be overcome before it can be successfully translated into therapeutic practice. This abstract highlights the revolutionary potential of microbiota-based approaches in cancer care and the need for ongoing research and technology improvements to harness the power of the tumor-associated microbiome for improved patient outcomes.
