Improved understanding of the underlying cellular dysfunction and resultant neuropathology of sporadic Alzheimer’s disease (AD) is needed to stem the anticipated public health crisis due to this increasingly common neurodegenerative disease. The four main risk factors for sporadic AD are age, female gender, genetic carriage of the APOE4 allele and type two diabetes mellitus (T2DM). Each of these four risk factors is associated with impaired and/or dysfunctional autophagy suggesting that perturbation of autophagy is [...]

Background: Phelan-McDermid syndrome (PMS), or 22q13.3 deletion syndrome, is a neurodevelopmental disorder with an estimated prevalence of 1 in 10,000 to 1 in 20,000 newborns. Although it usually occurs de novo with a low recurrence risk, an increased recurrence risk is observed in some families. In this paper, we provide an overview of the underlying causes of increased recurrence risk in families with PMS and present a workflow aimed at identifying an increased recurrence risk. Methods: First, we report clinical [...]

This review summarizes the latest results from the interventional clinical trials for inducing clinical tolerance in the recipients of human leukocyte antigen (HLA)-matched or mismatched living donor kidney transplants via allogeneic hematopoietic stem cell (HSC)-based therapies. The protocols utilized by the three medical centers in the United States differ in degree of HLA-matching, relatedness or unrelatedness, donor cell composition of the hematopoietic stem cells transplant (HSCT), timing for infusion and cond [...]

Obesity is on the rise and the number of end stage renal disease patients who are obese parallel this trend. There is no universally accepted guideline for wait-listing end stage renal disease obese patients in order to reduce surgical complications and improve survival of the kidney graft. Criteria for acceptance are variable among transplant centres, as do post-transplant policies. Careful risk assessment to maximise the benefits of the limited organ donor resource must be undertaken prior to waitlist an obese ki [...]

Thyroid transcription factor 1 (TTF-1) is a nuclear polypeptide and a tissue-restricted member of the homeobox protein family that, when attached to DNA, plays a crucial role in regulating the expression of select genes during early embryonic development of the thyroid, lung, and brain. As often happens, the initial enthusiasm for the diagnostic value of TTF-1 as a selective immunohistochemical marker of lung and thyroid tumors began to dwindle, due to its detection in tumors arising from other organs. TTF-1-expres [...]

Pneumocystis jirovecii pneumonia (PcP) remains a major cause of respiratory illness among immunocompromised patients. PcP is difficult to diagnose, in particular in non-HIV-infected patients, due to the lack of associated specific clinical data. Since P. jirovecii could not be cultivated for many years, microscopic visualization of cystic or trophic forms in respiratory specimens based on cytochemical or immunofluorescence staining are the standard procedure to identify this fungus. Polymerase chain reaction (PCR)- [...]

Background: Treatment of mood and anxiety disorders with supplements, herbs and nutraceuticals (dietary supplements) is at this point viewed as an integrative or alternative treatment, however these substances have been around for quite some time and are regarded as basic to the understanding of human biochemistry, physiology, health and illness in medicine. Methods: This review article was done using a literature search utilizing the National Library of Medicine online data base and the PCOM electronic library dat [...]

Infectious diseases are one of the most important causes of morbidity and mortality around the world and have a substantial impact on the health of communities. These diseases are caused by pathogenic microorganisms, such as bacteria, viruses, parasites and fungi. The antibiotics that are currently available are generally considered to be safe and well-tolerated. However antimicrobial resistance is an increasingly serious concern in the treatment of infectious diseases. An understanding of epigenetics now contribut [...]

Transplant tolerance has been achieved in experimental models using immune intervention strategies. Yet, their clinical translation remains unsuccessful and requires further optimization of immunotherapeutic regimens based on a deeper understanding of the cellular and molecular mechanisms at play in the induction and maintenance phases of immune tolerance. Intensive investigations have shed light on the tolerogenic networks underlying graft survival and have unraveled their complexity, which may depend on several p [...]
