Artificial Intelligence (AI) and Machine Learning (ML) are transforming drug discovery by overcoming traditional challenges like high costs, time-consuming, and frequent failures. AI-driven approaches streamline key phases, including target identification, lead optimization, de novo drug design, and drug repurposing. Frameworks such as deep neural networks (DNNs), convolutional neural networks (CNNs), and deep reinforcement learning (DRL) models have shown promise in identifying drug targets, optimizing delivery systems, and accelerating drug repurposing.

This study aims to develop a stable and efficient magnetic nanocomposite hydrogel (MNCH) for selective removal of methylene blue (MB) and crystal violet (CV). MNCHs with different FeO contents (0-9 wt%) were synthesized following graft co-polymerization method using sodium alginate, acrylamide, itaconic acid, ammonium persulfate and N,N-methylene bisacrylamide. Among them, MNCH, with 5 wt% FeO, showed highest removal efficiency (>95 %).

A method is proposed for fault classification in milling machines using advanced image processing and machine learning. First, raw data are obtained from real-world industries, representing various fault types (tool, bearing, and gear faults) and normal conditions. These data are converted into two-dimensional continuous wavelet transform (CWT) images for superior time-frequency localization.

Introduction: The cowpea weevil, Fab., is the most economically important storage pest of cowpeas, causing up to 100 percent grain losses within six months of storage. To sustainably resist weevil damage, the cowpea cultivar IT86D-1010 was genetically modified via -mediated transformation to produce event CSI-32, which expresses the kidney bean alpha-amylase inhibitor 1 (αAI-1) protein exclusively in the seed, providing suppression of weevil development.

Background: An inflammation of the nasal and paranasal sinus mucosa that lasts longer than three months is known as chronic rhinosinusitis. When corticosteroids and other medicinal treatments fail to relieve a patient's symptoms, then functional endoscopic sinus surgery (FESS) is a commonly performed procedure to alleviate the symptoms. The aim of the study was to evaluate the impact of oral steroids given prior to surgery on intraoperative bleeding in patients having functional endoscopic sinus surgery for chronic rhinosinusitis.

Background: Temporomandibular disorders (TMD) are a diverse set of musculoskeletal and neuromuscular problems involving the temporomandibular joint complex and surrounding muscles 1. TMD prevalence has varied from one location to the next, with estimates ranging from 6 to 68 % in various types Objectives were to compare the efficacy of NSAIDs with intra-articular injection of corticosteroids in patients suffering from temporomandibular disorders (TMD) due to disc displacement without reduction in terms of mean pain score and mean mouth opening. This Randomized control trial was conducted at the Oral & Maxillofacial Surgery Department, PMC Dental institute, Faisalabad Medical University, Faisalabad, Pakistan, from 6th April 2018 to 6th April 2019.

Accurate and reliable bearing-fault diagnosis is important for ensuring the efficiency and safety of industrial machinery. This paper presents a novel method for bearing-fault diagnosis using Mel-transformed scalograms obtained from vibrational signals (VS). The signals are windowed and pass through a Mel filter bank, converting them into a Mel spectrum.

Background: The increasing cases of chronic kidney disease is a global public health concern. The potential link between consumption of food contaminated with heavy metals and development of end stage renal disease is becoming an emerging challenge. This study aimed to identify heavy metal contaminants in food and environmental risk factors for development of chronic kidney disease in Nigeria.

Article Synopsis
  • Variceal bleeding is a serious issue for patients with cirrhosis, leading to higher risks of complications and death, particularly after an initial occurrence.
  • A systematic review assessed the effectiveness of endoscopic treatments like band ligation and TIPS, which showed better immediate outcomes, compared to pharmacological options like beta-blockers, which help manage long-term risks.
  • The study emphasizes tailored treatment plans combining both approaches to improve patient results and calls for further research on long-term benefits and cost-effectiveness.

Background: Sickle cell disease (SCD) is highly prevalent in Africa, especially in Nigeria, the most populous country, and is associated with a high mortality rate. Depression, common among individuals with SCD, correlates with increased pain intensity and opioid misuse, leading to poorer outcomes and diminished quality of life in these patients.

Aim: To determine whether major depressive disorder is a predictor of opioid use disorder among patients with sickle cell disease.

Article Synopsis
  • Fluorescent carbon quantum dots (CQDs) have low toxicity and unique properties, showing promise in combating plant pathogens, particularly viral infections like the cotton leaf curl Multan virus (CLCuMuV).
  • The research demonstrated that using optimized CQDs significantly reduced CLCuMuV levels and improved the health and photosynthetic efficiency of infected plants.
  • CQDs enhanced the plants' immune responses by affecting gene regulation linked to important pathways that fight viral infections and help maintain plant health.

Background: This evaluation research utilized both qualitative and quantitative methods to assess the implementation of the National Primary Health Care Development Agency (NPHCDA) gateway of the Basic Health Care Provision Fund (BHCPF) across six states in Northern Nigeria: Bauchi, Borno, Kaduna, Kano, Sokoto, and Yobe.

Methods: This was a mixed-method research that utilized longitudinal surveys and Key informant interviews to gather information about the implementation status of the BHCPF-NPHCDA gateway. Checklists were developed based on the BHCPF's national guidelines to gather quantitative data, while simple open-ended questionnaires were used to collect qualitative data from the state BHCPF Program Implementation Unit (PIU) focal persons as key informants.

Introduction: Access to quality antenatal care (ANC) is essential in reducing high maternal morbidity and mortality, especially in resource-poor countries. One way of ensuring financial accessibility to high-quality ANC services is through health insurance. This study assessed the perceived quality of services among insured and uninsured pregnant women attending the ANC at a tertiary health institution in Sokoto, Nigeria.

We created GNQA, a generative pre-trained transformer (GPT) knowledge base driven by a performant retrieval augmented generation (RAG) with a focus on aging, dementia, Alzheimer's and diabetes. We uploaded a corpus of three thousand peer reviewed publications on these topics into the RAG. To address concerns about inaccurate responses and GPT 'hallucinations', we implemented a context provenance tracking mechanism that enables researchers to validate responses against the original material and to get references to the original papers.

Key Clinical Message: Fungal endocarditis is a rare but potentially fatal infection with significant diagnostic and management challenges. Antifungal therapy and surgical debridement are the preferred treatments in these cases. Antimicrobial therapy with multiple antifungal agents may be required in high-risk patients presenting with prolonged fever suspected of having fungal endocarditis.
