Few public health problems have captured the attention of the biomedical and lay communities alike as has Alzheimer Disease (AD). Several questions remain still open in disease management, as the necessity to delineate disease process from “normal ageing”. In the last few years, Mild Cognitive Impairment (MCI) has received significant attention, thus it represents the major risk factor for AD. Not all people diagnosed a Read More

Post-translational modification of proteins by poly(ADP-ribosyl)ation is involved in the regulation of a number of biological functions. While an 18 member superfamily of poly(ADP-ribose) polymerases (PARP)s has been described PARP-1 accounts for more than 90% of the poly(ADP-ribosyl)ating capacity of the cells. PARP-1 act as a DNA nick sensor and is activated by DNA breaks to cleave NAD(+) into nicotinamide a Read More

An inflammatory process in the central nervous system (CNS) is believed to play an important role in the pathway leading to neuronal cell death in a number of neurodegenerative diseases including Parkinson's disease, Alzheimer's disease, prion diseases, multiple sclerosis and HIV-dementia. The inflammatory response is mediated by the activated microglia, the resident immune cells of the CNS, which normally respond to ne Read More

The blood-brain barrier (BBB) impedes the influx of intravascular compounds from the blood to the brain. The elements composing the BBB are endothelial cells, pericytes and the end-feet of astrocytes. Among them, the endothelial cell barrier line is the most critical for preventing toxic substances from entering the brain. In this review, we focus on the ultrastructural distribution of important components in the intracellul Read More

A combination of different HIV inhibitors into a single molecular entity is a strategy that is growing in popularity in HIVchemotherapy research. The high levels of resistance elicited by both nucleoside and non-nucleoside reverse transcriptase inhibitors has prompted the design of double-drugs combining these two entities with the aim of addressing the emergence of resistance. The strategy involves combining two different inhi Read More

Significant advances in therapeutic applications of proteins and peptides have brought new challenges in the field of drug development. Ordered protein aggregation known as amyloid formation has recently emerged as a universal phenomenon due to extensive research in protein folding and amyloid diseases. The amyloid represents a new generic structure characterized by cross-β-sheet formation in its core, which impli Read More

The envelope that encapsulates the cell nucleus has recently gained considerable interest, as several clinical syndromes are linked to mutations in its molecular components. Most disorders recognized so far are caused by defects in the nuclear lamins, building blocks of a filamentous network lining the nucleoplasmic side of the inner nuclear membrane. Nuclear lamins are the evolutionary precursors of cytoskeletal intermediat Read More

Selective estrogen receptor modulators (SERMs), known previously as “antiestrogens”, are a new category of therapeutic agents used for the prevention and treatment of diseases such as osteoporosis and breast cancer. SERMs act as ERagonist in some tissues while acting as ER-antagonist in others based on conformational change of the receptors, particularly at the helix 12. Currently, there are two classes of cli Read More

Serious infections caused by opportunistic molds remain a major problem for public health. Immune deficiency following organ transplantation and aggressive cancer treatment has greatly increased the incidence of systemic mycoses, and invasive aspergillosis in patients with AIDS is associated with significant morbidity and mortality. Amphotericin B is the first-line therapy for systemic infection because of its broad-spectrum and Read More

In our review entitled “DNA Repair Helicases as Targets for Anti-Cancer Therapy“ by Brosh et al. in Current Medicinal Chemistry, 2007, 14, 503-517. We wish to correct a mistake in the reference section which was overlooked. Reference numbers 114 and 115 were duplicated and also appear as 70 and 71 in the Reference List. Therefore, readers are advised that reference numbers 116-146 correspond to references 114-144 in t Read More
