The Impact

Aberrant cell surface glycosylation signatures are currently known to actively drive the neoplastic transformation of healthy cells. By disrupting the homeostatic functions of their protein carriers, cancer-associated glycans mechanistically underpin several molecular hallmarks of human malignancy. Furthermore, such aberrant glycan structures play key roles in the acquisition of molecular resistance to targeted therapeutic agents, which compromises their clinical efficacy, by modulating tumour cell aggressiveness and supporting the establishment of an immunosuppressive microenvironment. Recent advances in the study of the tumour cell glycoproteome have unravelled previously elusive molecular mechanisms of therapeutic resistance, guided the rational design of novel personalized therapeutic strategies, and may further improve the clinical performance of currently approved anti-cancer targeted agents. In this review, we highlight the impact of glycosylation in cancer targeted therapy, with particular focus on receptor tyrosine kinase-targeted therapy, immune checkpoints blockade therapy, and current developments on therapeutic strategies directed to glycan-binding proteins and other innovative glycan therapeutic strategies.

Initial Approach

AbstractIn the present work the author presents a literature update regarding the pharmacotherapeutic management of rapid cycling affective disorder. This phenomenon is characterized, according to Dunner and Fieve (1974), by the presence of at least four affective episodes per year. After a consideration of the clinical features of the disorder, which are in many respects similar to those of the ‘classic’ bipolar disorder, the author describes the different therapeutic strategies available to the psychiatrist. Withdrawal of antidepressant therapy and administration of lithium salts are likely to constitute the best initial approach. In case of treatment non-responsiveness, it is possible to consider the use of different drugs; for example, carbamazepine, sodium valproate, clorgyline, thyroid hormone. To date, the therapeutic management of rapid cyclers remains extremely difficult. Further studies, especially addressed to the aetiopathogenetic aspects of the disorder, are required.

Though there already had been notable progress in developing efficient therapeutic strategies for cancers, there still exist many requirements for significant improvement of the safety and efficiency of targeting cancer treatment. Thus, the rational design of a fully biodegradable and synergistic bioimaging and therapy system is of great significance. Metal organic framework (MOF) is an emerging class of coordination materials formed from metal ion/ion clusters nodes and organic ligand linkers. It arouses increasing interest in various areas in recent years. The unique features of adjustable composition, porous and directional structure, high specific surface areas, biocompatibility, and biodegradability make it possible for MOFs to be utilized as nano-drugs or/and nanocarriers for multimodal imaging and therapy. This review outlines recent advances in developing MOFs for multimodal treatment of cancer and discusses the prospects and challenges ahead.

It is known thatHelicobacter pyloriinfection is associated with chronic gastritis, peptic ulcer, and gastric carcinoma. Due to the increased side effects of the treatment regimens and the development of antimicrobial resistance, a number of natural compounds have been tested as potential alternatives. In this review, we will examine the current knowledge on the effect ofCitrusfruits and their derivatives againstH. pylori, highlighting the remaining outstanding questions on the development of novel therapeutic strategies.

Neurotoxic Effects

Alzheimer’s disease (AD) is a chronic neurodegenerative disease that has been recognized as one of the most intractable medical problems with heavy social and economic costs. Amyloid-β (Aβ) has been identified as a major factor that participates in AD progression through its neurotoxic effects. The major mechanism of Aβ-induced neurotoxicity is by interacting with membrane receptors and subsequent triggering of aberrant cellular signaling. Besides, Aβ transporters also plays an important role by affecting Aβ homeostasis. Thus, these Aβ receptors and transporters are potential targets for the development of AD therapies. Here, we summarize the reported therapeutic strategies targeting Aβ receptors and transporters to provide a molecular basis for future rational design of anti-AD agents.

AbstractAlthough sex and gender have a major impact on the susceptibility and immunologic response to infectious diseases, these factors are often neglected. Identifying the mechanisms underlying sex-based differences in infectious diseases will facilitate the rational design and implementation of preventive and therapeutic strategies that reduce risk and improve outcomes for women and men. In this article, we discuss two examples in neuroinfectious diseases of how sex matters: (1) the heightened risk of cerebrovascular disease in women living with HIV infection and (2) the implications of Zika virus infection on sexual and reproductive health and vaccine development for women.

Helicobacter pylori is a microaerophilic, gram-negative bacterium found in the upper gastrointestinal tract of humans. There is strong evidence that H. pylori is important in the etiology of gastritis; the bacterium may also be a major predisposing cause of peptic ulceration. On the gastric mucosa, the organism exists as a spiral form with one to seven sheathed flagella at one (usually) or both poles. Short spirals were seen in the first successful culture of the organism in 1983. In 1984, Marshall and Warren reported a coccoid form in older cultures. Since that time, other workers have observed rod and coccal forms in vitro; coccoid forms predominate in cultures 3-7 days old. We sought to examine the growth cycle of H. pylori in prolonged culture and the mode of coccoid body formation.
