Organ-on-a-chip systems, also referred to as microphysiological systems (MPS), represent an advance in bioengineering microsystems designed to mimic key aspects of human organ physiology and function. Drawing inspiration from the intricate and hierarchical architecture of the human body, these innovative platforms have emerged as invaluable in vitro tools with wide-ranging applications in drug discovery and development, as well as in enhancing our understanding of disease physiology. The facility to replicate human tissues within physiologically relevant three-dimensional multicellular environments empowers organ-on-a-chip systems with versatility throughout different stages of the drug development process.

Introduction: Saliva is a promising option for therapeutic drug monitoring, with studies since the 1970s indicating a good correlation between plasma and saliva levels for early anti-seizure medications, although limited data exist for newer generation drugs.

Objectives: To evaluate the reliability and predictive power of saliva as a minimally invasive surrogate marker of plasma concentration for the routine therapeutic drug monitoring (TDM) of newer anti-seizure medications (ASM).

Methods: We collected blood samples at steady state in patients at least 6 h post-dose, paired with unstimulated saliva samples.

Cancer remains a formidable global health challenge requiring the continued exploration of innovative therapeutic approaches. While traditional treatment strategies including surgery, chemotherapy, and radiation therapy have had some success, primarily in early-stage disease, the quest for more targeted, personalized, safer, and effective therapies remains an ongoing pursuit. Over the past decade, significant advances in the field of tumor immunology have dramatically shifted a focus towards immunotherapy, although the ability to harness and coopt the immune system to treat cancer is still just beginning to be realized.

Globally, the incidence and death rates associated with cancer persist in rising, despite considerable advancements in cancer therapy. Although some malignancies are manageable by a mix of chemotherapy, surgery, radiation, and targeted therapy, most malignant tumors either exhibit poor responsiveness to early identification or endure post-treatment survival. The prognosis for prostate cancer (PCa) is unfavorable since it is a perilous and lethal malignancy.

January 2025

College of Biology and Food Engineering, Chongqing Three Gorges University, Chongqing, 404100, China.

Insulin resistance was considered to be the most important clinical phenotype of type 2 diabetes (T2DM). Almond is a widely-consumed nut and long-term intake was beneficial to alleviating insulin resistance in patients with T2DM. Hence, screening of anti-diabetic peptides from almond proteins was feasible based on the effectiveness of peptides in the treatment of T2DM.

Antibodies targeting either the calcitonin gene-related peptide (CGRP), such as galcanezumab, fremanezumab, and eptinezumab, or the receptor (erenumab) have been approved for the prevention of episodic and chronic migraine. Although widely used and generally effective, a proportion of patients discontinue treatment due to lack of efficacy. In both randomized controlled trials and observational studies, all anti-CGRP monoclonal antibodies (mAbs) have consistently demonstrated comparable efficacy and tolerability, suggesting a pharmacological class effect.

In every heartbeat, cardiac muscle cells perform excitation-Ca signaling-contraction (EC) coupling to pump blood against the vascular resistance. Cardiomyocytes can sense the mechanical load and activate mechano-chemo-transduction (MCT) mechanism, which provides feedback regulation of EC coupling. MCT feedback is important for the heart to upregulate contraction in response to increased load to maintain cardiac output.
