Medicinal Fungi with Antiviral Effect
Medicinal fungi are not only crude extracts, but also that some single components, such as proteins, polysaccharides and terpenoids, can effectively combat viral infection. Some of these medicinal fungi also have inhibitory effects on a variety of viruses. The complex components are closely related to its multi-target and multi-link action mechanism. Some medicinal fungi, including Poria cocos and Polyporus umbellatus, have been widely used in clinical practice. Because of the special properties of medicinal fungi, it is better than that of traditional medicine, which is more beneficial to be used as a kind of health food.

Light as a Cure in COVID-19
The history of the use of light in modern medicine dates to the early 1900s, when Finsen reported significant recoveries of smallpox patients exposed to red light compared to unexposed controls. Finsen was awarded the Nobel Prize in 1903 “in recognition of his contribution to the treatment of diseases, especially lupus vulgaris, with concentrated light radiation, whereby he has opened a new avenue for medical science". The exceptional demonstrations of N.R. Finsen have inaugurated a new stage in contemporary medicine regarding the effectiveness of light therapies, followed by implementing new laser technologies after Endre Mester incidentally detected the positive effect of a ruby laser beam on hair growth and wound healing in mice. Originally called Low Level Light/Laser Therapy (LLLT), nowadays, photobiomodulation (PBM) is a modality that consists of projecting light to influence the activity of living cells, tissues, and even the entire organism to stimulate the immune system, promote tissue repair, advance healing, decrease inflammation, and control pain.

Hepatitis B Virus Core Protein in Hepatocarcinogenesis
Chronic hepatitis B virus (HBV) infection is one of the most common factors associated with hepatocellular carcinoma (HCC), which is the sixth most prevalent cancer among all cancers worldwide. The mechanisms underlying HBV-induced malignant transformation remain unclear, but some studies have suggested that the hepatitis B virus core (HBc) protein has a potential function in the pathogenesis of hepatocellular carcinoma in addition to the HBV X protein. This review focuses its discussion on the involvement of HBc in the development of hepatocellular carcinoma.

Importance of Magnesium Status in COVID-19
Magnesium is an essential nutrient, also called an essential mineral or element. Magnesium is vastly important in all life, with vital roles for the healthy functioning of the human immune, metabolic, neurological, psychological, and heart and circulatory systems. Magnesium (Mg) status may have relevance for the outcome of COVID-19 and that Mg could be protective during the COVID disease course: (1) low magnesium status is associated with the severity of COVID-19 outcomes, including mortality, and with several disease-related neurological symptoms, including loss of memory, taste, and/or smell; (2) inhaled magnesium as a therapy may improve oxygen status; and (3) magnesium therapy, alone or in combination with zinc, may increase the effectiveness of anti-COVID-19 medications.

Prevalence of Vancomycin-Resistant Enterococcus in Poultry in Malaysia
Enterococcus has emerged as a significant nosocomial and community-acquired pathogen as a result of its ability to develop resistance to antimicrobials, particularly vancomycin. Vancomycin is the final treatment option, particularly for Enterococcus. There is abundant proof that drug-resistant bacteria exist in poultry and can be transmitted to humans. Regular monitoring of vancomycin-resistant Enterococcus (VRE) in poultry would aid policymakers in developing effective control measures and design antimicrobial resistance (AMR) surveillance capacity building in Malaysia. Further, livestock farmers should be educated on antibiotics resistance and trained on responsible utilization of antibiotics.

Diagnosis of Paracoccidioidomycosis
Paracoccidioidomycosis (PCM) is a systemic mycosis endemic to Latin America caused by thermodimorphic fungi of the genus Paracoccidioides. Enhanced understanding of the phylogenetic species concept and molecular variations has led to changes in this genus’ taxonomic classification. Although the impact of the new species on clinical presentation and treatment remains unclear, they can influence diagnosis when serological methods are employed. Brazil accounts for 80% of PCM cases worldwide, and its incidence is rising in the northern part of the country (Amazon region), owing to new settlements and deforestation, whereas it is decreasing in the south, owing to agriculture mechanization and urbanization. Clusters of the acute/subacute form are also emerging in areas with major human intervention and climate change. Advances in diagnostic methods (molecular and immunological techniques and biomarkers) remain scarce, and even the reference center’s diagnostics are based mainly on direct microscopic examination.

Current Methods for Bacterial Infection Clinical Diagnosis
Antimicrobial resistance (AMR), defined as the ability of microorganisms to withstand antimicrobial treatment, is responsible for millions of deaths annually. The rapid spread of AMR across continents warrants systematic changes in healthcare routines and protocols. One of the fundamental issues with AMR spread is the lack of rapid diagnostic tools for pathogen identification and AMR detection. Resistance profile identification often depends on pathogen culturing and thus may last up to several days. This contributes to the misuse of antibiotics for viral infection, the use of inappropriate antibiotics, the overuse of broad-spectrum antibiotics, or delayed infection treatment.

Redefining Vaccine Effectiveness through Lessons from SARS-CoV-2
Anti-SARS-CoV-2 vaccines have played a pivotal role in reducing the risk of developing severe illness from COVID-19, thus helping end the COVID-19 global public health emergency. Intriguingly, as SARS-CoV-2 variants emerged, individuals who were fully vaccinated did get infected in high numbers, and viral loads in vaccinated individuals were as high as those in the unvaccinated. However, vaccines undoubtedly offered protection against severe illness even without conferring immunity in the classical sense. The lessons learned from anti-SARS-CoV-2 vaccines are a call to the medical community to revisit and redefine the concept of vaccine effectiveness. This endeavor is likely to increase increase vaccine confidence, and thus bolster global health education efforts and preventive care.

Effectiveness of COVID-19 Vaccines against Delta (B.1.617.2) Variant
The high transmissibility, mortality, and morbidity rate of the SARS-CoV-2 Delta (B.1.617.2) variant have raised concerns regarding vaccine effectiveness (VE). The short-term effectiveness of the Pfizer-BioNTech, Moderna, AstraZeneca, Bharat Biotech, and CoronaVac vaccines for the prevention of infection and the reduction in the severity of illness and hospitalizations associated with the Delta variant are supported.

Tuberculosis and Autoimmunity
It is long-established that pathogenesis of many autoimmune diseases is mainly promoted by inadequate immune responses to bacterial agents, among them Mycobacterium tuberculosis. Tuberculosis is a multifaceted process having many different outcomes and complications. Autoimmunity is one of the processes characteristic of tuberculosis; the presence of autoantibodies was documented by a large amount of evidence. The role of autoantibodies in pathogenesis of tuberculosis is not quite clear and widely disputed. They are regarded as: (1) a result of imbalanced immune response being reactive in nature, (2) a critical part of TB pathogenicity, (3) a beginning of autoimmune disease, (4) a protective mechanism helping to eliminate microbes and infected cells, and (5) playing dual role, pathogenic and protective. There is no single autoimmunity-mechanism development in tuberculosis; different pathways may be suggested. It may be excessive cell death and insufficient clearance of dead cells, impaired autophagy, enhanced activation of macrophages and dendritic cells, environmental influences such as vitamin D insufficiency, and genetic polymorphism, both of Mycobacterium tuberculosis and host.

Neutrophils and Flaviviruses
Neutrophils are first-line responders to infections and are recruited to target tissues through the action of chemoattractant molecules, such as chemokines. Neutrophils are crucial for the control of bacterial and fungal infections, but their role in the context of viral infections has been understudied. Flaviviruses are important human viral pathogens transmitted by arthropods. Infection with a flavivirus may result in a variety of complex disease manifestations, including hemorrhagic fever, encephalitis or congenital malformations. Our understanding of flaviviral diseases is incomplete, and so is the role of neutrophils in such diseases. Here we present a comprehensive overview on the participation of neutrophils in severe disease forms evolving from flavivirus infection, focusing on the role of chemokines and their receptors as main drivers of neutrophil function. Neutrophil activation during viral infection was shown to interfere in viral replication through effector functions, but the resulting inflammation is significant and may be detrimental to the host. For congenital infections in humans, neutrophil recruitment mediated by CXCL8 would be catastrophic.
