Biotics and the Gut Barrier
Increased gut permeability is suggested to be involved in the pathogenesis of a growing number of disorders. The altered intestinal barrier and the subsequent translocation of bacteria or bacterial products into the internal milieu of the human body induce the inflammatory state. Gut microbiota maintains intestinal epithelium integrity. Since dysbiosis contributes to increased gut permeability, the interventions that change the gut microbiota and correct dysbiosis are suggested to also restore intestinal barrier function

Cross-Cultural Psychology
Cross-cultural psychology is the scientific study of human behavior and mental processes, including both their variability and invariance, under diverse cultural conditions. Through expanding research methodologies to recognize cultural variance in behavior, language, and meaning it seeks to extend and develop psychology. Since psychology as an academic discipline was developed largely in North America and Europe, some psychologists became concerned that constructs accepted as universal were not as invariant as previously assumed, especially since many attempts to replicate notable experiments in other cultures had varying success. Since there are questions as to whether theories dealing with central themes, such as affect, cognition, conceptions of the self, and issues such as psychopathology, anxiety, and depression, may lack external validity when "exported" to other cultural contexts, cross-cultural psychology re-examines them using methodologies designed to factor in cultural differences so as to account for cultural variance. Some critics have pointed to methodological flaws in cross-cultural psychological research, and claim that serious shortcomings in the theoretical and methodological bases used impede, rather than help the scientific search for universal principles in psychology. Cross-cultural psychologists are turning more to the study of how differences (variance) occur, rather than searching for universals in the style of physics or chemistry. While cross-cultural psychology represented only a minor area of psychology prior to WWII, it began to grow in importance during the 1960s. In 1971, the interdisciplinary Society for Cross-Cultural Research (SCCR) was founded, and in 1972 the International Association for Cross-Cultural Psychology (IACCP) was established. Since then, this branch of psychology has continued to expand as there has been an increasing popularity of incorporating culture and diversity into studies of numerous psychological phenomena. Cross-cultural psychology is differentiated from cultural psychology, which refers to the branch of psychology that holds that human behavior is strongly influenced by cultural differences, meaning that psychological phenomena can only be compared with each other across cultures to a limited extent. In contrast, cross-cultural psychology includes a search for possible universals in behavior and mental processes. Cross-cultural psychology "can be thought of as a type [of] research methodology, rather than an entirely separate field within psychology". In addition, cross-cultural psychology can be distinguished from international psychology which centers around the global expansion of psychology especially during recent decades. Nevertheless, cross-cultural psychology, cultural psychology, and international psychology are united by a common concern for expanding psychology into a universal discipline capable of understanding psychological phenomena across cultures and in a global context.

Food Supply Chain's Business-Models Innovation
This paper investigates the contribution of business model innovations in the advancement of novel food supply chains. Through a systematic literature review, the notable business model innovations in the food industry are identified, surveyed, and evaluated. Findings reveal that the innovations in the value proposition, value creation processes, and value delivery processes of business models are the successful strategies proposed in the food industry. It is further disclosed that rural female entrepreneurs, social movements, and also urban conditions are the most important driving forces causing farmers to reconsider their business models. In addition, the new technologies and environmental factors are the secondary contributors in business model innovation for the food processors. It is concluded that digitalization has disruptively changed the food distributor models. E-commerce models and Internet-of-Things are reported as essential factors causing retailers to innovate their business models. Furthermore, consumption demand and product quality are two main factors affecting the business models of all the firms operating in the food supply chain regardless of their positions in the chain. The findings of the current study provide an insight into the food industry to design a sustainable business model to bridge the gap between food supply and food demand.

PTMs Role During Virus Infection
Viruses are opportunistic intracellular pathogens that are dependent on the host for their replication. They hijack host cellular machinery for their replication and survival by targeting crucial cellular physiological pathways, including transcription, translation, immune pathways, and apoptosis. Immediately after translation, the host and viral proteins undergo a process called post-translational modification (PTM). PTMs of proteins involves the attachment of small proteins, carbohydrates/lipids, or chemical groups to the proteins and are crucial for protein's functioning. During viral infection, host proteins utilize PTMs to control the virus replication, using strategies like activating immune response pathways, inhibiting viral protein synthesis, and ultimately eliminating the virus from the host. PTM of viral proteins increases solubility, enhances antigenicity and virulence properties. However, RNA viruses are devoid of enzymes capable of introducing PTMs to their proteins. Hence, they utilize the host PTM machinery to promote their survival. Proteins from viruses belonging to the family: Togaviridae, Flaviviridae, Retroviridae, and Coronaviridae such as chikungunya, dengue, zika, HIV, and coronavirus are a few well-known to be modified. This review discusses various host and virus-mediated PTMs that play a role in the outcome during the infection.

Machine-Learning-Based Disease Diagnosis
Machine learning (ML), an area of artificial intelligence (AI), enables researchers, physicians, and patients to solve some of these issues. Many researchers and practitioners illustrate the promise of machine-learning-based disease diagnosis (MLBDD), which is inexpensive and time-efficient. Traditional diagnosis processes are costly, time-consuming, and often require human intervention. While the individual’s ability restricts traditional diagnosis techniques, ML-based systems have no such limitations, and machines do not get exhausted as humans do. As a result, a method to diagnose disease with outnumbered patients’ unexpected presence in health care may be developed. To create MLBDD systems, health care data such as images (i.e., X-ray, MRI) and tabular data (i.e., patients’ conditions, age, and gender) are employed.

Hydroxytyrosol and Oleuropein in Aging and Related Disorders
Aging is a multi-faceted process caused by the accumulation of cellular damage over time, associated with a gradual reduction of physiological activities in cells and organs. This degeneration results in a reduced ability to adapt to homeostasis perturbations and an increased incidence of illnesses such as cognitive decline, neurodegenerative and cardiovascular diseases, cancer, diabetes, and skeletal muscle pathologies. Key features of aging include a chronic low-grade inflammation state and a decrease of the autophagic process. The Mediterranean diet has been associated with longevity and ability to counteract the onset of age-related disorders. Extra virgin olive oil, a fundamental component of this diet, contains bioactive polyphenolic compounds as hydroxytyrosol (HTyr) and oleuropein (OLE), known for their antioxidant, anti-inflammatory, and neuroprotective properties.

Media Pluralism
Media pluralism defines the state of having a plurality of voices, opinions and analyses on media system (internal pluralism) or the coexistence of different and diverse types of medias and media support (external pluralism). Media pluralism is often recognized by international organizations and non-governmental organizations as being an essential part of a democratic state, Reporters Without Borders considers "access to a plurality of editorial lines and analyses [as] essential for citizens to be able to confront ideas, to make their own informed choices and to conduct their life freely". Expanded access to the Internet and the digital switch-over has enabled an increased availability of media content, largely through sharing and user-generated content on social media, in addition to the digital channels to which individuals have access across television and radio. The diversity of content is however accompanied by what Hallin and Mancini call polarized pluralism in a media system. According to the World Trends Report, a sharper division in the way we use news is coming up due to the interaction between consumption habits, changing economic models and technical systems. This signifies that even if multiple kinds of information and programming are available, each segmented group may only ingest one branch of the whole. The increase of Internet penetration and reliance on online sources for news is thought of to producing siloed debates. At the infrastructural level, ‘zero rating’— in which Internet or mobile service providers allow users to access specific content or applications without counting towards the user’s data ‘cap’— expands in parallel to mobile uptakes, particularly in emerging countries. Traditional business models for the news media continue to be disrupted, leading to vertical and horizontal concentration and introduction of new types of ownership. Challenges to media funding introduce new types of economic models such as pay-walls and crowd-funding initiatives. Gender is a part of media pluralism and is characterized by the under-representation of women in the media workforce, in decision-making and in media content. People with disabilities are also under-represented in the media system.
