    Abstract Livestock is a fundamental part of the agriculture industry in Pakistan and contributes more than 11.53% to GDP. Among livestock species, the buffaloes are regarded as the black gold of Pakistan. Being the highest milk producers globally, Nili-Ravi buffaloes are the most famous ones. Buffaloes are affected by many endemic diseases, and "Hemorrhagic septicemia" (HS) is one of them. This study was designed to ascertain the effects of experimental exposure ofP. multocida B:2 (oral) and its immunogens, i.e., LPS (oral and intravenous) and OMP (oral and subcutaneous) on reproductive hormonal profiles in Nili-Ravi buffaloes. Repeated serum samples were collected from the jugular vein of experimental animals for 21 days (0, 02, 04, 08, 12, 16, 20, 24, 36, 48, 72, 120, 168, 216, 264, 360, 456 and 504 hours). Hormonal assays to determine the serum concentrations of Gonadotropin-releasing hormone (GnRH), Follicle-stimulating hormone (FSH), Luteinizing hormone (LH), Estrogen (E2) and progesterone (P4) were performed using (MyBioSource) commercial Elisa kits. The hormonal profile of all treatment groups of the buffalo heifers exhibited significant (P<0.05) variations as compared to the control group (G-1). These results indicate suppression in Nili-Ravi buffaloes' reproductive hormonal profile on exposure to P. multocida B:2 and its immunogens. This influence warrants that exposure to H.S may be a possible reason for delayed puberty and poor reproduction performance in Nili-Ravi buffaloes.

    Abstract Hive bees provide essential pollination services to human agriculture. Managed honey bees in particular pollinate many crops, but also create honey and other bee products that are now of global economic importance. Key aspects of honey bee behaviour and colony health can be understood by observing hives. Hence, the limitations of manual observation are increasingly being addressed by new technologies that automate and extend the reach of hive monitoring. Here we propose a framework to classify and clarify the potential for sensor-assisted hive monitoring to inform apiculture and, ultimately, improve hive bee management and bee health. This framework considers hive monitoring approaches across three newly proposed categories: Operational monitoring, Investigative monitoring, and Predictive monitoring. These categories constitute a new "OIP Framework" of hive monitoring. Each category has its own requirements for underlying technology that includes sensors and ICT resources we outline. Each category is associated with particular outcomes and benefits for apiculture and hive health monitoring detailed here. Application of these three classes of sensor-assisted hive monitoring can simplify understanding and improve best-practice management of hive bees. Our survey and classification of hive monitoring to date show that it is seldom practised beyond honey bees, despite the need to understand bumble bees and stingless bees also. Perhaps unsurprisingly, sensor-based hive monitoring is shown to remain primarily a practice of countries with upper-middle and high income economies. Yet we show benefits from which all countries, especially countries with lower-middle and low income economies, stand to gain through improved sensor-based hive monitoring. These include a better understanding of environmental change, an increased ability to manage pollination, an ability to respond rapidly to hive health issues such as pests and pathogens, and even an ability to react quickly to the danger posed to insects and humans alike by extreme events such as floods and fires. Hive health is a critical issue for bees, beekeepers, horticulture and ecosystem sustainability. We show that its assessment requires a rigorous and coherent approach that has not yet been adequately formalised. Finally, we anticipate that the future of hive monitoring lies in the application of Predictive monitoring, such that a hive's anticipated future state can be preemptively managed by beekeepers working iteratively with novel hive monitoring technologies.

    Abstract Bioscience is an interdisciplinary venture. Driven by a quantum shift in the volume of high throughput data and in ready availability of data-intensive technologies, mathematical and quantitative approaches have become increasingly common in bioscience. For instance, a recent shift towards a quantitative description of cells and phenotypes, which is supplanting conventional qualitative descriptions, has generated immense promise and opportunities in the field of bench-to-bedside cancer OMICS, chemical biology and pharmacology. Nevertheless, like any burgeoning field, there remains a lack of shared and standardized framework for quantitative cancer research. Here, in the context of cancer, we present a basic framework and guidelines for bench-to-bedside quantitative research and therapy. We outline some of the basic concepts and their parallel use cases for chemical-protein interactions. Along with several recommendations for assay setup and conditions, we also catalog applications of these quantitative techniques in some of the most widespread discovery pipeline and analytical methods in the field. We believe adherence to these guidelines will improve experimental design, reduce variabilities and standardize quantitative datasets.

    Abstract Ischemia-reperfusion (I/R) is considered the primary cause of acute kidney injury and is higher among older individuals. Although ischemic episodes are hard to predict and prevent, detrimental ischemic effects could be mitigated by exogenous intervention. This study aimed to identify the protective role of angiotensin (1-7) [ANG(1-7)] against I/R-induced renal injury in adult versus aged rats. Adult and aged male Fisher 344 rats were subjected to 40 min of bilateral renal ischemia followed by 28 days of reperfusion. ANG(1-7) was administered intraperitoneally in ischemic rats for 28 days with or without the Mas receptor antagonist A779. I/R increased blood pressure, plasma creatinine, urinary 8-isoprostane, and renal infiltration of pro- and anti-inflammatory macrophages and reduced glomerular filtration rate in both adult and aged rats compared with sham rats. In addition to causing glomerular sclerosis and tubular damage, I/R increased the expression of the following pathogenic miRNAs: miR-20a-5p, miR-21-5p, miR-24-3p, and miR-194-5p in both age groups. ANG(1-7) treatment of ischemic rats mitigated oxidative stress and renal inflammation, restored renal structure and function, and reduced high blood pressure. Also, ANG(1-7) suppressed the expression of pathogenic miRNAs. In addition, ANG(1-7) treatment of I/R rats increased the expression of the redox-sensitive transcription factor nuclear factor-erythroid factor 2-related factor 2 (NRF2) and phase II antioxidant enzymes. The beneficial effects of ANG(1-7) were sensitive to A779. Collectively, these data suggest that ANG(1-7) associated with NRF2 activation could alleviate post-I/R-induced kidney injury, and therefore serve as a potential therapeutic compound to protect against biochemical and morphological pathologies of I/R in both adults and aged populations.

    Abstract The suppressor of TCR signaling (Sts) proteins, Sts-1 and Sts-2, are a pair of closely related signaling molecules that belong to the histidine phosphatase (HP) family of enzymes by virtue of an evolutionarily conserved C-terminal phosphatase domain. HPs derive their name from a conserved histidine that is important for catalytic activity and the current evidence indicates that the Sts HP domain plays a critical functional role. Sts-1

    Abstract A woman in her 20s presented with neck pain, slurred speech and left-sided weakness. She successfully underwent mechanical thrombectomy (MT) for total occlusion of the basilar artery and made full neurological recovery. Initial ultrasound Doppler of legs (USDL) did not show any deep vein thrombosis (DVT). However, 2 days later, a repeat USDL revealed an extensive proximal DVT in the right common femoral vein. CT scan confirmed a haematoma arising from the femoral access site causing compression of the adjacent common femoral vein. This may have initiated DVT formation or exacerbated extension of a previously undetected DVT. Echocardiogram revealed a patent foramen ovale. As the patient was asymptomatic, delayed or missed diagnosis of DVT would have put her at risk of life-threatening pulmonary embolism or further strokes. Clinicians should maintain a high index of suspicion of DVT as a direct procedural complication from MT so treatment can be initiated promptly.

    Abstract Thermal images have various applications in security, medical and industrial domains. This paper proposes a practical deep-learning approach for thermal image classification. Accurate and efficient classification of thermal images poses a significant challenge across various fields due to the complex image content and the scarcity of annotated datasets. This work uses a convolutional neural network (CNN) architecture, specifically ResNet-50 and VGGNet-19, to extract features from thermal images. This work also applied Kalman filter on thermal input images for image denoising. The experimental results demonstrate the effectiveness of the proposed approach in terms of accuracy and efficiency.
