Many drugs are effective systemically, but slow onset of non-intravenous routes of administration may limit their clinical utility. While anesthesiologists usually have intravenous (IV) access for drug delivery, other healthcare professionals in less controlled situations such as acute crises in the emergency room, critical care settings, or urgent needs in the community, may need non-invasive drug delivery [1].

Adult neurons in the mammalian central nervous system (CNS) fail to regenerate after injury due to a number of factors including the reduced intrinsic growth capacity together with the hostile environment of the injured CNS microenvironment [1-4]. However recent studies have shown that modifying the intrinsic growth capacity through a number of cell signalling pathways can promote regeneration of adult CNS neurons. For example, intrinsic factors such as cyclic adenosine monophosphate (cAMP), mammalian target of rapamycin (mTOR), and the repressors phosphatase and tensin homolog (PTEN) and suppressor of cytokine signalling 3 (SOCS3) promote CNS axon regeneration [5-7]. 

Mesenchymal stem cells (MSCs) are widely used in regenerative medicine. They can be isolated from different adult tissues. However, the regenerative potential of MSCs obtained from various sources and from different age donors may significantly differ.

The action potential (AP) in cardiac tissue is important for initiating and coordinating contractions in the heart. In addition, the long refractory period minimizes the potential for developing extrasystoles and arrhythmias. The AP is generated by coordinate changes in different ionic currents. In human (or canine) adult ventricular cells, the depolarization phase of the AP is mainly through the influx of Na+ and Ca2+ through specific voltage gated channels.

In many metazoan tissues, highly specialized cells are constantly lost and need to be replaced by tissue homeostasis from adult stem cells. When adult stem cells divide by mitosis their daughter cells either become new stem cells, or enter a proliferation and differentiation path. Recent studies in Drosophila males showed that germline stem cells (GSCs) can increase their mitotic activity in response to repeated mating.

Liver masses account for 5 to 6% of pediatric cancer, which includes hepatoblastoma (HBL) along with rare cases of hepatocellular carcinoma (HCC). The most dangerous form of pediatric liver cancer is aggressive HBL, which can be characterized by chemo-resistance and multiple nodules or metastases at diagnosis, all correlating with worse clinical prognosis. Despite intensive studies and a significant improvement in overall outcomes, very little is known about the key molecular pathways which determine the aggressiveness of pediatric liver cancer.

Stem cell therapy for the treatment of cerebral palsy is a rapidly expanding area of research that has been identified as a high priority by consumers. There are several types and sources of stem cell therapies under investigation. Stem cell treatments proposed for cerebral palsy are believed to provide benefit via some or all of the following mechanisms including immunomodulation, paracrine signaling and supporting endogenous reparative processes.

Sleeve gastrectomy is the most common bariatric surgery worldwide. However, such a surgery caries risk of complications associated with morbidity and mortality. Gastric leak can occur and represents one of the most severe complications following sleeve gastrectomy. Since the two last decades, regenerative medicine has emerged, offering new strategies to face to sleeve gastrectomy complications.

Radiation therapy (RT) is one of the pillars of locally advanced head and neck cancer (HNSCC) treatment in combination with cisplatin or epidermal growth factor receptor inhibitors. Despite a very high local tumor control rate, approximately 50% of patients with locally advanced disease will develop a recurrence.

The effects of COVID-19 have been of increasing interest in all fields of medicine after the pandemic, especially considering the important impact and incidence of patients infected with coronavirus. Numerous studies have reported the vast clinical implications related to permanent organ and tissue damage after infection and long COVID. 

Neural circuits' role in regulating neurogenesis within the adult subventricular zone (SVZ) of the lateral ventricles (LV) has been extensively studied over the past two decades. The dynamic interplay between neurons, neurotransmitters, and LV neural stem cells (NSCs) highlights the critical influence of neural circuits on NSC renewal, proliferation, and differentiation.

Neuropsychiatric disorders have been the constant burden impacting healthcare since 1990, and more than 3 billion people worldwide are living with neurological conditions. Mental health conditions with cognitive decline were also observed in people who contracted SARSCoV-2 and later presented the PACS related disease after the resolution of primary infection. 

Bioengineering is a new discipline of science that apply engineering principles and techniques on the biological process for development of valuable bioactive molecule, designing metabolites and changing cells or cellular metabolites to combat the current as well as future challenges and problem of mankind. This is one of the most challenging fields testing the researcher’s intelligence, dedication, skill and creativity and courage needed to contradict convention and cut new pathways through unexplored scientific terrain.

Transient receptor potential (TRP) family is a large superfamily of widely expressed ion channels. In recent years, several studies have been conducted on the mechanism of action of TRP. However, studies on the role of TRP in liver diseases are limited. In fact, TRP plays a vital role in the progression of many liver diseases, such as hepatic fibrosis, hepatocellular carcinoma, alcoholic fatty liver disease, and nonalcoholic fatty liver disease.

Parkinson’s disease (PD) is the second most common neurodegenerative disease, manifesting as a characteristic movement disorder with a number of additional non-motor features. The pathological hallmark of PD is the presence of intra-neuronal aggregates of a-synuclein (Lewy bodies). The movement disorder of PD occurs largely due to loss of dopaminergic neurons of the substantia nigra, resulting in striatal dopamine depletion.

The one conceptual key to improving newborn healthcare outcomes is thought to be bridging the access gap to care, particularly in sub-Saharan Africa. However, recent studies have reported conflicting results relative to establishing a link between outcomes and access to care intervention programs.

Background and Aim: Non-Alcoholic Fatty Liver Disease (NAFLD) is the commonest cause of chronic liver disease and is a leading cause of liver transplantation in the United States, with no approved medication to halt or reverse its progression. Recent animal-model prospective trial-suggested that drug Vedolizumab leads to improvement and reversal in the NAFLD-related metabolic derangements. Vedolizumab is an α4β7 integrin-inhibitor that is approved for use in IBD patients. Our study aims to understand Vedolizumab's impact on the course of NAFLD in inflammatory bowel disease (IBD) patients.

The pediatric liver cancer hepatoblastoma (HBL) has a complex etiology which is not yet determined. In contrast to adult liver cancer hepatocellular carcinoma (HCC), pediatric HBL has a low rate of genetic mutations suggesting that other mechanisms play a critical role in development of this disease.

Malan syndrome (Sotos Syndrome 2, OMIM 614753) is a rare autosomal dominant overgrowth disorder caused by either chromosome 19p13.2/19p13.13 microdeletion or Nuclear Factor 1 X-Type (NFIX) gene haploinsufficiency. Symptoms typically appear in infancy and include dysmorphic features, seizures, and behavioral issues; however, the degree of immune system involvement is not clear. Herein, we are reporting a case of Malan syndrome who presented to the immunology clinic with recurrent bacterial infections, including three episodes of pneumonia confirmed by chest X-ray.

Recent research underscores the risk posed by plastic compounds to pediatric liver health. These compounds can permeate the maternal-fetal-child barrier through the placenta and breastfeeding, exposing fetus/child to potential harm during crucial developmental stages [1,2].
