Abstract
Neuroimaging is a highly important field of neuroscience, with direct implications for the early diagnosis and progression monitoring of brain-associated diseases. Neuroimaging techniques are categorized into structural, functional and molecular neuroimaging, each possessing advantages and disadvantages in terms of resolution, invasiveness, toxicity of contrast agents and costs. Nanotechnology-based approaches for neuroimaging mostly involve the development of nanocarriers for incorporating contrast agents or the use of nanomaterials as imaging agents. Inorganic and organic nanoparticles, liposomes, micelles, nanobodies and quantum dots are some of the most studied candidates for the delivery of contrast agents for neuroimaging. This paper focuses on describing the conventional modalities used for imaging and the applications of nanotechnology for developing novel strategies for neuroimaging. The aim is to highlight the roles of nanocarriers for enhancing and/or overcome the limitations associated with the most commonly utilized neuroimaging modalities. For future directions, several techniques that could benefit from the increased contrast induced by using imaging probes are presented.

Abstract
Intracerebral hemorrhage (ICH) is a common and severe cerebrovascular disease that has high mortality. Few survivors achieve self-care. Currently, patients receive only symptomatic treatment for ICH and benefit poorly from this regimen. Inflammatory cytokines are important participants in secondary injury after ICH. Increases in proinflammatory cytokines may aggravate the tissue injury, whereas increases in anti-inflammatory cytokines might be protective in the ICH brain. Inflammatory cytokines have been studied as therapeutic targets in a variety of acute and chronic brain diseases; however, studies on ICH are limited. This review summarizes the roles and functions of various pro- and anti-inflammatory cytokines in secondary brain injury after ICH and discusses pathogenic mechanisms and emerging therapeutic strategies and directions for treatment of ICH.

Abstract
So far, intravenous tissue-type plasminogen activator (tPA) and mechanical
removal of arterial blood clot (thrombectomy) are the only available treatments
for acute ischemic stroke. However, the short therapeutic window and the lack of
specialized stroke unit care make the overall availability of both treatments
limited. Additional agents to combine with tPA administration or thrombectomy to
enhance efficacy and improve outcomes associated with stroke are needed.
Stroke-induced inflammatory processes are a response to the tissue damage due to
the absence of blood supply but have been proposed also as key contributors to
all the stages of the ischemic stroke pathophysiology. Despite promising results
in experimental studies, inflammation-modulating treatments have not yet been
translated successfully into the clinical setting. This review will (a) describe
the timing of the stroke immune pathophysiology; (b) detail the immune responses
to stroke sift-through cell type; and (c) discuss the pitfalls on the
translation from experimental studies to clinical trials testing the therapeutic
pertinence of immune modulators.
