Angiotensin II Type 2 Receptor
Preclinical evidence, accumulated over the past decade, indicates that the angiotensin II type 2 receptor (AT2R) stimulation exerts significant neuroprotective effects in various animal models of neuronal injury, notably in the central nervous system.   Studies of brain AT2R distribution and function are outshining the recent findings about AT2R in peripheral sensoryneurons and pain modulation. While AT2R, as an atypical G protein-coupled receptor, and its related signaling are still under investigation, pharmacological studies have shown that stimulation of AT2R leads to neuritogenesis in vitro and in vivo. This review aims to report the evidence of potential neuroprotective and neuroregenerative roles of AT2R in the peripheral nervous system (PNS).

Lymphedema
Secondary lymphedema is a common complication of lymph node dissection or radiation therapy for cancer treatment. Conventional therapies such as compression sleeve therapy, complete decongestive physiotherapy, and surgical therapies decrease edema; they are not curative because they cannot modulate the pathophysiology of lymphedema.

Oral Glucose Tolerance Test
The oral glucose tolerance test (OGTT) has been the mainstay for diagnosing gestational diabetes for decades. However, this test is cumbersome, deeply flawed, and has reduced reproducibility. In this review, we explore a history of the OGTT, its reproducibility, and the many factors that can impact its results with an emphasis on pregnancy.

Honey and Propolis in Ocular Disease Treatment
Honey and propolis have recently become the key target of attention for treating certain diseases and promoting overall health and well-being. A high content of flavonoids and phenolic acids found in both honey and propolis contributes to the antioxidant properties to scavenge free radicals. Honey and propolis also exhibited antibacterial effects where they act in two ways, namely the production of hydrogen peroxide (H2O2) and gluconic acids following the enzymatic activities of glucose oxidase, which exerts oxidative damage on the bacteria. Additionally, the anti-inflammatory effects of honey and propolis are mainly by reducing proinflammatory factors such as interleukins and tumor necrosis factor alpha (TNF-α). Their effects on pain were discovered through modulation at a peripheral nociceptive neuron or binding to an opioid receptor in the higher center. The aforementioned properties of honey have been reported to possess potential therapeutic topical application on the exterior parts of the eyes, particularly in treating conjunctivitis, keratitis, blepharitis, and corneal injury. In contrast, most of the medicinal values of propolis are beneficial in the internal ocular area, such as the retina, optic nerve, and uvea.

Vitamin D Target Genes
The biologically active form of vitamin D3, 1α,25-dihydroxyvitamin D3 (1,25(OH)2D3), modulates innate and adaptive immunity via genes regulated by the transcription factor vitamin D receptor (VDR). In order to identify the key vitamin D target genes involved in these processes, transcriptome-wide datasets were compared, which were obtained from a human monocytic cell line (THP-1) and peripheral blood mononuclear cells (PBMCs) treated in vitro by 1,25(OH)2D3, filtered using different approaches, as well as from PBMCs of individuals supplemented with a vitamin D3 bolus. The led to the genes ACVRL1, CAMP, CD14, CD93, CEBPB, FN1, MAPK13, NINJ1, LILRB4, LRRC25, SEMA6B, SRGN, THBD, THEMIS2 and TREM1. Public epigenome- and transcriptome-wide data from THP-1 cells were used to characterize these genes based on the level of their VDR-driven enhancers as well as the level of the dynamics of their mRNA production.

Pluripotent Stem Cell
Pluripotent stem cells (PSC) such as embryonic stem cells (ESC) and induced PSCs (iPSC) are originated from embryos and induced from adult tissue cells, respectively. PSCs are capable of proliferating almost indefinitely, and differentiating into all somatic cells, through processes that mimic early embryogenesis. The resulting cells tend to carry embryonic characteristics.

Pathogenesis of COVID-19
The systemic manifestations commonly observed in COVID-19 patients include hypertension, arterial and venous thromboembolism, kidney disease, cerebrovascular disorders, and diabetes mellitus). These clinical findings strongly suggest that the virus is targeting the endothelium. Here we report a systematic and comprehensive evaluation of the evidence showing that the endothelium is a key target organ in COVID-19, playing a fundamental role in its pathogenesis.

LC-MS/MS for the Diagnosis of Organic Acidemias
Liquid chromatography-tandem mass spectrometry (LC-MS/MS) has already been used in many clinical laboratories for a broad range of clinical tests, such as therapeutic drug monitoring (TDM) and the analysis of hormones and vitamins, as well as organic acid analysis.

Leaky Gut and Autoimmunity
Damage to the tissue and the ruining of functions characterize autoimmune syndromes. This review centers around leaky gut syndromes and how they stimulate autoimmune pathogenesis. Lymphoid tissue commonly associated with the gut, together with the neuroendocrine network, collaborates with the intestinal epithelial wall, with its paracellular tight junctions, to maintain the balance, tolerance, and resistance to foreign/neo-antigens. The physiological regulator of paracellular tight junctions plays a vital role in transferring macromolecules across the intestinal barrier and thereby maintains immune response equilibrium. A new paradigm has explained the intricacies of disease development and proposed that the processes can be prevented if the interaction between the genetic factor and environmental causes is barred by re-instituting the intestinal wall function. The latest clinical evidence and animal models reinforce this current thought and offer the basis for innovative methodologies to thwart and treat autoimmune syndromes.

Castration-Resistant Prostate Cancer
Castration-resistant prostate cancer (CRPC) is defined as castrate serum testosterone levels (<50 ng/dL or 1.7 nmol/L) plus either biochemical or radiological progression, as specified in the European Association of Urology guidelines.
