Personalization has always been an important aspect of business and with the popularization of e-commerce as well as with the advances in technology; personalization has become vital to achieve customer interest, engagement, satisfaction and loyalty, positively impacting the sales. Recommendation systems act as a key component of the entire personalization cycle by reducing the information overload and recommending items as per the interest of the customer and helping the customer in decision making. Recommendation systems have been evolved from rule-based to Artificial Intelligence (AI)- and Machine Learning (ML)-based systems. The introduction of Generative AI has taken personalization to the next level. However, excessive use of AI may lead to homogeneity in recommendation leading to bias in decision making and affecting diversity of recommendations. AI-based recommendation systems need to strike a right balance in personalization and consumer behavior in order to achieve more realistic and sustainable personalization goals.

From 2000 to 2019, the global malaria death toll fell from 864,000 to 576,000 deaths; however, progress on reducing this toll has since slowed, with the COVID-19 pandemic contributing to an increase in the mortality rate since 2020. The emergence of widespread resistance in the major malaria parasite (Plasmodium falciparum) to first-line treatment drugs has highlighted the need for new antimalarials and smarter drug delivery strategies. Nevertheless, recent successes of the first malaria vaccines (RTS,S/AS01 and R21/MM) have renewed the promise of widely applicable vaccines in the future. Since 2015, the Eastern Mediterranean Region has experienced an overall increase in malaria cases and deaths. In the Arabian Peninsula, while most of the Gulf Cooperation Council (GCC) countries have been declared free of indigenous malaria (Bahrain, Kuwait, Qatar, and the United Arab Emirates), malaria is still endemic in two GCC countries (Saudi Arabia and Oman) and their neighbors (Yemen). Furthermore, a number of factors threaten malaria control in this region, especially antimalarial drug resistance, the emergence of highly invasive mosquito species, increasing average temperatures, and imported malaria. In this review, we assess the current worldwide status of malaria before providing a critical evaluation of the malaria situation in the GCC countries.

The increasing threat of zoonotic malaria parasites of humans, such as Plasmodium knowlesi, make the search for improved pharmacotherapy imperative. Using protein sequence and structural analyses, phylogenetics, protein network mapping, protein–ligand interaction, and small molecule docking studies, we have identified for the first time the predicted structure, function, and druggability of the P. knowlesi heat shock protein 90s (PkHsp90s). Four isoforms were identified (in the cytosol, endoplasmic reticulum, mitochondrion, and apicoplast), and key structural differences were elucidated compared to human Hsp90s. In particular, the glycine-rich helix loop (GHL) motif of cytosolic PkHsp90 was predicted to have a straight conformation that forms a plasmodial-specific hydrophobic extension of the lid domain of the ATP-binding site, which was not observed for the cytosolic human Hsp90s, HSPC1 (Hsp90α), and HSPC3 (Hsp90β). Virtual screening identified for the first time a number of compounds from the ZINC database (ZINC22007970, ZINC724661072, and ZINC724661078) that were predicted to bind strongly to the GHL-associated pocket of PkHsp90, with weak or no binding to HSPC1. This study has provided a molecular framework in support of rational drug design, targeting PkHsp90s as a promising route for antimalarial drug development in the fight against zoonotic malaria.

Plasmodium knowlesi is a zoonotic form of human malaria, the pathology of which is poorly understood. While the J domain protein (JDP) family has been extensively studied in Plasmodium falciparum, and shown to contribute to malaria pathology, there is currently very limited information on the P. knowlesi JDPs (PkJDPs). This review provides a critical analysis of the literature and publicly available data on PkJDPs. Interestingly, the P. knowlesi genome encodes at least 31 PkJDPs, with well over half belonging to the most diverse types which contain only the signature J domain (type IIIs, 19) or a corrupted version of the J domain (type IVs, 2) as evidence of their membership. The more typical PkJDPs containing other domains typical of JDPs in addition to the J domain are much fewer in number (type IIs, 8; type Is, 2). This study indentifies PkJDPs that are potentially involved in: folding of newly synthesized or misfolded proteins within the P. knowlesi cytosol (a canonical type I and certain typical type IIs); protein translocation (a type III) and folding (a type II) in the ER; and protein import into mitochondria (a type III). Interestingly, a type II PkJDP is potentially exported to the host cell cytosol where it may recruit human HSP70 for the trafficking and folding of other exported P. knowlesi proteins. Experimental studies are required on this fascinating family of proteins, not only to validate their role in the pathology of knowlesi malaria, but also because they represent potential anti-malarial drug targets.

The human malaria parasite, Plasmodium falciparum, accounts for more than 500,000 deaths worldwide per year. From 2000 to 2019, the malaria global death toll fell from 864,000 to 576,000 deaths; however, progress on reducing this toll has since slowed, with the COVID-19 pandemic contributing to an increase in the mortality rate since 2020. The emergence of widespread resistance in P. falciparum to first-line treatment drugs has highlighted the need for new antimalarial drugs, and smarter approaches, including better combination therapies and mass drug administration. Nevertheless, recent successes of the first malaria vaccine (RTS,S/AS01) and the approval of a second (R21/MM), have renewed the promise of widely applicable vaccines in the future. Since 2015, the Eastern Mediterranean Region has experienced an overall increase in malaria cases and deaths. In the Arabian Peninsula, while most of the Gulf Cooperation Council (GCC) countries have been declared free of indigenous malaria (Bahrain, Kuwait, Qatar, and the United Arab Emirates), malaria is still endemic in two GCC countries (Saudi Arabia and Oman) and its neighbors (Yemen). Furthermore, a number of factors threaten malaria control in this region, at the level of the parasite (antimalarial drug resistance), the mosquito (the emergence of highly invasive species), the environment (climate change and increasing average temperatures), and society (imported malaria). In this review, we assess the current world-wide status of malaria in terms of public health, prevention and treatment, before providing an Arabian regional perspective, with a critical evaluation of the malaria situation in the GCC countries.

Crime is a complex issue that impacts the livability of communities worldwide. Indian cities' informal settlements are also becoming unsafe, which has a negative psychological impact on residents. In rapid urbanization, crime prevention is being neglected during the process of physical transformation. Informal settlements are characterized by an unplanned built environment, high densities of houses, unhealthy and barren open spaces, and streets, among other livability issues. Maqboolpura, located in Punjab, India, has faced significant challenges related to crime, including gang violence, drug trafficking and substance abuse, theft and burglary, prostitution, and human trafficking. These issues have not only threatened the safety and security of people but have also adversely affected the livability of the informal settlements. The crime rate in this area has been persistently high. Locals' sense of safety is negatively affected by these rates, along with their ability to enjoy the surroundings. A better understanding of these issues is necessary for addressing the community's livability challenges and implementing effective solutions to improve security and safety. Inhabitants also face livability challenges such as inadequate infrastructure, a lack of community spaces, and transitional spaces. Adaptive livability measures increase the livability of informal settlements and prevent crime. This reduces crime and increases the safety, life, and interconnectedness of Maqboolpura. This study reveals how livability initiatives can decrease crime in informal settlements. It enhances the physical and mental health of the community and its inhabitants.
