Citrate is an important intermediate in the citric acid cycle, a vital metabolic pathway for animals, plants and bacteria. It is of great significance to detect its levels in human beings because several diseases may cause the abnormal of citrate. In this paper, a new turn-on fluorescent sensor (TPE-Py) using the classic tetraphenylethylene (TPE) as the aggregation-induced emission (AIE) fluorophore and bipyridinium-based amides as the recognition receptor has been synthesized for the detection of citrate. The probe exhibits good selectivity and sensitivity to citrate with a relatively low detection limit (1...

Methylmercury (CH3Hg(+)) is the common form of organic mercury and is more toxic than its inorganic or elemental forms. Mercury is emanated in the course of various natural events and human activities and converts to methylmercury by anaerobic organisms. CH3Hg(+) are ingested by fish and subsequently bioaccumulated in their tissue and, eventually, enter the human diet, causing serious health issues. Therefore, selective and sensitive detection of bioaccumulated CH3Hg(+) in fish samples is essential. Herein, the development of a simple, highly sensitive and selective aggregation-induced emission (AIE)-based turn-on probe for both inorganic mercury ions and organicmercury species is reported...

Pleural effusion (PE) is a common clinical complication of many pulmonary and systemic diseases, including lung cancer and tuberculosis. Nevertheless, there is no clinical effective biomarker to identify the cause of PE. We attempted to investigate differential expressed exosomal miRNAs in PEs of lung adenocarcinoma (APE), tuberculous (TPE), and other benign lesions (NPE) by using deep sequencing and quantitative polymerase chain reaction (qRT-PCR). As a result, 171 differentiated miRNAs were observed in 3 groups of PEs, and 11 significantly differentiated exosomal miRNAs were validated by qRT-PCR...

Porphyrin- or phthalocyanine-bridged silsesquioxane nanoparticles (BSPOR and BSPHT) were prepared. Their endocytosis in MCF-7 cancer cells was shown with two-photon excited fluorescence (TPEF) imaging. With two-photon excited photodynamic therapy (TPE-PDT), BSPOR was more phototoxic than BSPHT, which in contrast displayed a very high signal for photoacoustic imaging in mice.

We surveyed multiple apheresis centers represented by the authors for their clinical approach to the management of anticoagulation issues during therapeutic plasma exchange (TPE). We present the results of their practices and a review of the pertinent literature. As plasma is removed during TPE, replacement with all or partial non-plasma-containing fluids (eg, 5% albumin) may lead to significant changes in hemostasis. These changes are amplified in patients who are receiving anticoagulation. We discuss various anticoagulants as well as the monitoring and adjustment of anticoagulation before, during, and after TPE...

Molecular rotors have played an important role in recent materials chemistry. Although several studies on functional materials containing molecular rotors have been reported for fluorescence sensing, this concept has yet to be realized in two-dimensional (2D) materials. Here we report the preparation of all-carbon, π-conjugated 2D porous organic nanosheets, named NUS-24, which contain flexible tetraphenylethylene (TPE) units as the molecular rotors. NUS-24 nanosheets exhibit high stability, large lateral size, and ultrathin thickness (2-5 nm)...

'Mind the gap' is a recorded warning phrase used in the London Tube since 1969. The following article is meant to be a warning of an increasing knowing-doing gap in routine practice of therapeutic plasma exchange (TPE), a treatment method that is used more and more throughout the world. The American Society of Apheresis recommendations, including the most recent ones from 2016, suggest using a TPE volume of 1.0-1.5 times the actual calculated plasma volume of the patient. There are only a few exceptions to that rule, such as the recommnded exchange volume in vasculitis or mushroom poisoning...

Despite evidence suggesting an anti-Mycobacterium tuberculosis effector function of CD4+ T cells that produce and retain IL-22 in macaques, the general role of IL-22 in tuberculosis infection is still poorly characterized. To explore the immune mechanism in the pathogenesis of tuberculosis in humans, here we evaluated different forms of IL-22 in populations with different tuberculosis infection statuses. We enrolled 156 subjects including 49 patients with pulmonary tuberculosis, 27 patients with tuberculous pleurisy (TPE), 38 individuals with latent tuberculous infection (LTBI) and 42 healthy controls (HC)...

l-Lactate is a vital biomarker for many diseases and physiological fatigue. An AIE-active fluorophore (TPE-HPro) is combined with l-lactate oxidase (LOx) to determine l-lactate in aqueous fluid. The assay shows excellent sensitivity and anti-interference performance with a limit of detection (LOD) of 5.5 μM. In addition, sensitive detection of l-lactate is achieved even in a protein-rich environment. It is proposed that quantification of l-lactate be performed at 20 or 60 min in the current method. These characteristics endow the fluorometric assay with great potential for biomedical diagnostics...
