This review aimed to provide a critical appraisal of alternative antimicrobial strategies in lieu of traditional triple antibiotic paste (TAP).
 
  This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The literature search was performed in 8 databases (PubMed/Medline, Embase, LILACS, Web of Science, Scopus, BVS, SciELO, and the Cochrane Library), selecting clinical, invitro, invivo, and in situ studies that evaluated antimicrobial alternatives to TAP in regenerative endodontics. Studies lacking an experimental TAP group were excluded.
 
  A total of 1705 potentially relevant records were initially identified. From the 38 studies retrieved for full-text reading, 16 fulfilled all selection criteria and were included in the qualitative analysis. According to the study design, 11 studies were solely invitro, 1 study was both invitro and invivo (animal model), 2 studies were solely animal experiments, and 2 studies were clinical trials. The alternative antimicrobial agent, as well as the use of natural compounds, deserving future investigation.
  Regenerative endodontic therapy (RET) has gained considerable attention and wide approval. Although it is being performed routinely, the outcomes remain unpredictable, and the optimal approaches for treatment are not established. It has been shown that bacterial persistence in root canals in these cases significantly interferes with healing and root maturation. However, few objective clinical studies have evaluated the complex microflora present in the infections or the efficacy of various clinical procedures. In addition, the extent of the infection and biofilm maturation in immature teeth with necrotic pulp has been understudied. Furthermore, most models used in preclinical evaluation of these issues do not fully elucidate the complexity or variability of the clinical situation.
 
  In this review, the main biological and clinical problems pertaining to RET will be discussed. Contemporary analysis of complex microbial communities will be reviewed with emphasis on how these types of analyses can provide clinnces and progress in endodontics, will be outlined.Spontaneous healing and recovery of innervated and vascularized tissues are limited. In particular, the complexity of the central nervous system's anatomy, physiology, and pathobiology make efforts to develop effective therapeutic strategies exceptionally challenging. Repairing the brain after injury implies restoring the tissue architecture of the neural and vascular networks both morphologically and functionally. The substantial clinical burden and disability after a central nervous system injury urges the need to explore therapeutic solutions outside the confine of conventional approaches used in regenerative medicine. Recent advances in tissue engineering and material sciences have developed biomimetic materials that can be injected or implanted directly to the site of damage to provide physical support to cell infiltration and growth, promoting tissue development and de novo formation of vascular and axonal networks through cell transplantation and/or controlled release of bioactive cues. These approaches have shown promise in promoting the endogenous repair machinery of the brain and controlling the growth and development of functional vascular and neural networks in the lesion to promote long-term functional recovery. This narrative review presents a comprehensive look at recent advances using proangiogenic engineered materials and drug delivery systems for brain repair after stroke.
  The improvement of regenerative endodontic procedures requires an understanding of the key clinical questions combined with a fundamental biological knowledge of how the dental tissues behave during health, disease, and repair. Therefore, partnerships between clinicians and basic scientists are essential to drive the field forward and improve patient outcomes.
 
  This review aimed to provide a background to dentin-pulp biology and the interaction between infection, inflammation, and regeneration.
 
  We have highlighted how the release of neutrophil extracellular traps (NETs) within the pulp are double-edged; while they aim to limit the bacterial infection, they may actually exacerbate cell death and chronic inflammation. Aberrant levels of these structures may occur because of ineffective host immunologic processes, viral infections, or impaired clearance caused by bacterial virulence factors. We also postulate a proinflammatory link in the pulp between NETs and the inflammasome activated by pathogen-associated molecular patterns and damage-associated molecular patterns. Subsequently, we discuss areas potentially fruitful for future clinical exploitation involving NET inhibitors, inflammasome modulators, phototherapies, and novel epigenetic approaches.
 
  Sustained scientist-clinician research partnerships along with an increased understanding of the association between inflammation and regeneration within the dentin-pulp complex will lead to future patient benefit.

These outcomes suggest that intravascular hemolysis predominantly independent of hypersplenism may underlie, at least to some extent, peripheral hemolysis in patients with PMF. More cases studies are needed to elucidate the role of splenomegaly in PMF-associated anemia.Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel coronavirus responsible for the coronavirus disease -19 (COVID-19). Since December 2019, SARS-CoV-2 has infected millions of people worldwide, leaving hundreds of thousands dead. Chloroquine (CQ) and Hydroxychloroquine (HCQ) are antimalarial medications that have been found to have in vitro efficacy against SARS-CoV-2. Several small prospective studies have shown positive outcomes. However, this result has not been universal, and concerns have been raised regarding the indiscriminate use and potential side effects. The clinicians are conflicted regarding the usage of these medications. Appropriate dose and duration of therapy are unknown. Here, we will discuss the pharmacokinetic and pharmacodynamic properties of CQ and HCQ, as well as review the antiviral properties. The manuscript will also examine the available data from recent clinical and preclinical trials in order to shed light on the apparent inconsistencies.
