Background: This study investigated diurnal variations in spirometric parameters and their correlation with salivary cortisol levels among apparently healthy adults.

Methods: Forty subjects, aged 18-22, were assessed. Spirometric parameters, including forced vital capacity (FVC), forced expiratory volume in one second (FEV1), forced expiratory flow during 25%-75% of expiration, and peak expiratory flow rate, were measured in the morning, afternoon, and evening.

Article Synopsis
  • The study aimed to assess the relationship between fibroid vascularization and heavy menstrual bleeding (HMB) using 3D power Doppler and superb microvascular imaging (SMI) in 75 women, dividing them into those with HMB and those without.
  • Results revealed that women with HMB had significantly higher flow rates (peak systolic and end-diastolic velocities) and lower resistance indices in the dominant fibroid's feeding vessel compared to those without HMB.
  • SMI analysis showed a stark contrast in vascularity grades, with 72% of women with HMB exhibiting higher vascularity compared to only 4% in the non-HMB group, highlighting the association between fibroid vascularity and HMB.

Background: The new competency-based curriculum incorporates the social sciences and humanism to the basic and clinical sciences, thus giving an integrated approach to medical education. Comparing the empathy score with the motivation level across the two curricula was thus planned to assess the current status.

Method: A cross-sectional qualitative study using an Internet-based electronic survey containing both an academic motivation scale to assess the motivation level and Jefferson's scale of empathy was used to assess empathy score.

Background: Antenatal hydronephrosis (ANH) is a common prenatal finding that requires careful evaluation to determine appropriate management strategies. The variability in outcomes underscores the need for refined diagnostic and monitoring protocols to differentiate between cases necessitating intervention and those likely to resolve spontaneously.

Materials And Methods: A prospective clinical study was conducted involving 150 pregnant women diagnosed with ANH between gestational weeks 18 to 24.

The rapid growth of the Internet of Things (IoT) has led to the widespread adoption of the IoT networks in numerous digital applications. To counter physical threats in these systems, automatic modulation classification (AMC) has emerged as an effective approach for identifying the modulation format of signals in noisy environments. However, identifying those threats can be particularly challenging due to the scarcity of labeled data, which is a common issue in various IoT applications, such as anomaly detection for unmanned aerial vehicles (UAVs) and intrusion detection in the IoT networks.

Article Synopsis
  • The cell wall of soybeans faces damage from polygalacturonases (PGs) produced by fungi, leading to disease and loss of quality.
  • Soybeans possess a resistance protein called polygalacturonases-inhibiting proteins (PGIPs) that bind to PGs, with specific mutations in PGIPs influencing their effectiveness against fungal infections.
  • Research using docking and molecular dynamics simulations reveals the structural interactions between gmPGIP and ssPG, providing insights for engineering soybean varieties that are more resistant to fungal attacks, potentially increasing crop yields.

There is an urgent need to combat pathogen infestations in crop plants to ensure food security worldwide. To counter this, plants have developed innate immunity mediated by Pattern Recognition Receptors (PRRs) that recognize pathogen-associated molecular patterns (PAMPs) and damage- associated molecular patterns (DAMPs). PRRs activate Pattern-Triggered Immunity (PTI), a defence mechanism involving intricate cell-surface and intracellular receptors.

Objective Doppler velocimetry is an established method of antepartum fetal surveillance in pre-eclampsia. Cerebroplacental ratio detects the centralization of fetal blood flow and the insufficiency in placental circulation. It is postulated to be a better marker of perinatal outcome than either vessel Doppler alone.

Of late, image compression has become crucial due to the rising need for faster encoding and decoding. To achieve this objective, the present study proposes the use of canonical Huffman coding (CHC) as an entropy coder, which entails a lower decoding time compared to binary Huffman codes. For image compression, discrete wavelet transform (DWT) and CHC with principal component analysis (PCA) were combined.

 Hemoglobin A1c (HbA1c) level remains the gold standard test for the assessment of glycemic control, and it reflects the mean glucose values in the previous 3-month period. HbA1c is expressed as a percentage, whereas the monitoring and treatment of diabetes are based on blood glucose levels expressed as mg/dL. It is appropriate to make it easy for the patient to understand both random blood sugar (RBS) and estimated average glucose (eAG) expressed with the same units.

Transcriptome sequencing or RNA-Sequencing is a high-resolution, sensitive and high-throughput next-generation sequencing (NGS) approach used to study non-model plants and other organisms. In other words, it is an assembly of RNA transcripts from individual or whole samples of functional and developmental stages. RNA- is a significant technique for identifying gene predictions and mining functional analysis that improves gene ontology understanding mechanisms of biological processes, molecular functions, and cellular components, but there is limited information available on this topic.

(FL) enables multiple clients to train a shared model collaboratively without sharing any personal data. However, selecting a model and adapting it quickly to meet user expectations in a large-scale FL application with heterogeneous devices is challenging. In this paper, we propose (FedMSA), which includes a hardware-aware model selection algorithm that trades-off model training efficiency and model performance base on FL developers' expectation.
