Advances in MALDI Mass Spectrometry Imaging Single Cell and Tissues.

Compared with conventional optical microscopy techniques, mass spectrometry imaging (MSI) or imaging mass spectrometry (IMS) is a powerful, label-free analytical technique, which can sensitively and simultaneously detect, quantify, and map hundreds of biomolecules, such as peptides, proteins, lipid, and other organic compounds in cells and tissues. So far, although several soft ionization techniques, such as desorption electrospray ionization (DESI) and secondary ion mass spectrometry (SIMS) have been used for imaging biomolecules, matrix-assisted laser desorption/ionization (MALDI) is still t

Altered Long Noncoding RNA Expression Profile in Multiple Myeloma Patients with Bisphosphonate-Induced Osteonecrosis of the Jaw.

Bisphosphonates (BPs) are inhibitors of osteoclast-mediated bone resorption used for the treatment of multiple myeloma (MM) patients with osteolytic lesions. Bisphosphonate-induced osteonecrosis of the jaw (BONJ) is an infrequent drug-caused adverse event of these agents. Long noncoding RNAs (lncRNAs) are a set of more than 200 base pairs, noncoding RNA molecules, which are critical posttranscriptional regulators of gene expression. Our study was aimed at evaluating 17 lncRNAs, whose targets were previously validated as key elements in MM, bone metabolism, and angiogenesis in MM subjects witho

What Is Precision Psychotherapy?

Precision medicine impacts virtually all medical specializations, including psychiatry. Although precision psychiatry, in general, is a flourishing area of research and debate, psychotherapy as one pillar of psychiatry receives little attention. Theoretical discussions about precision psychotherapy are rare; research on precision in psychotherapy is just evolving. In this paper, we provide a conceptualization of precision psychotherapy providing a common idea of what should be understood as precision in the context of psychotherapy and what kind of psychotherapy research is considered to contr

Иммунотерапевтический ландшафт амиотропического бокового склероза: библиометрический анализ тенденций в области исследований, приоритетов в области перевода и сетей сотрудничества (см.2006-2025).

Амиотрофный боковой склероз (ALS) по-прежнему является серьезной терапевтической проблемой, при этом иммунная диагностика все чаще признается в качестве одного из важнейших факторов развития заболеваний. Несмотря на обширные механистические исследования, никакой иммунотерапевтический подход не привел к последовательному изменению болезней, в связи с чем возникают вопросы о том, отражает ли этот переводный пробел биологическую сложность или структурную несогласованность в исследовательской экосистеме. Чтобы охарактеризовать интеллектуальную эволюцию исследований иммунотерапевтии ALS, определить

Pressures do not equal volumes: implications for heart failure management in patients with CardioMEMS.

Pulmonary arterial pressures are often used as surrogates for intravascular blood volume. However, the relationship between pressure and volume remains controversial. To contextualize and provide concrete examples and impact on clinical management, we report two cases of heart failure (one in heart failure with reduced ejection fraction and one in heart failure with preserved ejection fraction) where pressure-based measurements did not accurately represent the intravascular status and affected clinical management.

Harnessing the potential of CAR-T cell therapy: progress, challenges, and future directions in hematological and solid tumor treatments.

Traditional cancer treatments use nonspecific drugs and monoclonal antibodies to target tumor cells. Chimeric antigen receptor (CAR)-T cell therapy, however, leverages the immune system's T-cells to recognize and attack tumor cells. T-cells are isolated from patients and modified to target tumor-associated antigens. CAR-T therapy has achieved FDA approval for treating blood cancers like B-cell acute lymphoblastic leukemia, large B-cell lymphoma, and multiple myeloma by targeting CD-19 and B-cell maturation antigens. Bi-specific chimeric antigen receptors may contribute to mitigating tumor anti

Биомаркеры по исследованиям в области клинической медицины: исследование литературы в базе данных PubMed и критическая оценка.

Биомаркер, короткая форма "биологического маркера", появилась в научной литературе в 1940-х годах. С тех пор было предложено множество различных определений, однако общеприменимое объяснение термина " биомаркер " в науке является чрезвычайно сложным. Слово "биомаркер" встречается в 1.3 million статьи в научной базе данных PubMed , которая в настоящее время включает более 39 million Ссылки на биомедицинскую литературу. Биомаркеры тесно связаны со здоровьем и болезнями человека. В настоящей статье делается попытка подойти к многогранному термину "биомаркет" и оценить его с клинической

Further, global-screening-array was performed to evaluate association of these polymorphisms in Prakriti stratified 200 CAD patients and 100 healthy controls. Th

Nanoparticle-Based RNAi Therapeutics Targeting Cancer Stem Cells: Update and Prospective.

Cancer stem cells (CSCs) are characterized by intrinsic self-renewal and tumorigenic properties, and play important roles in tumor initiation, progression, and resistance to diverse forms of anticancer therapy. Accordingly, targeting signaling pathways that are critical for CSC maintenance and biofunctions, including the Wnt, Notch, Hippo, and Hedgehog signaling cascades, remains a promising therapeutic strategy in multiple cancer types. Furthermore, advances in various cancer omics approaches have largely increased our knowledge of the molecular basis of CSCs, and provided numerous novel targ

Global, regional, and national comparative risk assessment of 84 behavioural, environmental and occupational, and metabolic risks or clusters of risks for 195 countries and territories, 1990-2017: a systematic analysis for the Global Burden of Disease Study 2017.

BACKGROUND: The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 comparative risk assessment (CRA) is a comprehensive approach to risk factor quantification that offers a useful tool for synthesising evidence on risks and risk-outcome associations. With each annual GBD study, we update the GBD CRA to incorporate improved methods, new risks and risk-outcome pairs, and new data on risk exposure levels and risk-outcome associations. METHODS: We used the CRA framework developed for previous iterations of GBD to estimate levels and trends in exposure, attributable deaths, and

Delivery of miR-34a by chitosan/PLGA nanoplexes for the anticancer treatment of multiple myeloma.

The encapsulation of miR-34a into chitosan/PLGA nanoparticles in order to obtain nanoplexes useful for the modulation of the biopharmaceutical features of the active compound was studied. The nanoplexes were obtained through nanoprecipitation and were characterized by a mean diameter of ~160 nm, a good size distribution and a positive surface charge. The structure of the nanoparticles allowed a high level of entrapment efficiency of the miR-34a and provided protection of the genetic material from the effects of RNase. A high degree of transfection efficiency of the nanoplexes and a significant

Cryopreservation Preserves Cell-Type Composition and Gene Expression Profiles in Bone Marrow Aspirates From Multiple Myeloma Patients.

Single-cell RNA sequencing reveals gene expression differences between individual cells and also identifies different cell populations that are present in the bulk starting material. To obtain an accurate assessment of patient samples, single-cell suspensions need to be generated as soon as possible once the tissue or sample has been collected. However, this requirement poses logistical challenges for experimental designs involving multiple samples from the same subject since these samples would ideally be processed at the same time to minimize technical variation in data analysis. Although cr
