The Application of Regional Citrate Anticoagulation in Protein A Immunoadsorption: A Single-Center Retrospective Cohort Study.

Introduction: Protein A immunoadsorption (IA) is proving to be an effective treatment method for autoimmune diseases and other disorders. Regional citrate anticoagulation (RCA) prevents clotting in extracorporeal circuits without increasing hemorrhage risk in high bleeding risk patients, but there are no specific guidelines for its application in IA. We aimed to evaluate the safety and adverse effects of RCA used in IA therapy.

Chemotypic diversity of bioprotective grass endophytes based on genome analyses, with new insights from a Mediterranean-climate region in Isfahan Province, Iran.

species are systemic, often seed-transmissible symbionts (endophytes) of cool-season grasses (Poaceae subfam. Poöideae) that produce up to four classes of bioprotective alkaloids. Whereas haploid species may reproduce sexually and transmit between host plants (horizontally), many species are polyploid hybrids that are exclusively transmitted via seeds (vertically).

Reactivation of senescence-associated endogenous retroviruses by ATF3 drives interferon signaling in aging.

Reactivation of endogenous retroviruses (ERVs) has been proposed to be involved in aging. However, the mechanism of reactivation and contribution to aging and age-associated diseases is largely unexplored. In this study, we identified a subclass of ERVs reactivated in senescent cells (termed senescence-associated ERVs (SA-ERVs)).

Background: As synthesis technology advances, novel and efficient derivatives of tetracyclines are found. Three new antibiotics were approved within the past 18 years, and represent a new era in the use of tetracyclines. To gain further insight into adverse events linked to tetracyclines and better protect pediatric patients, ongoing monitoring of safety data is crucial.

Prognosis of concurrent renal impairment at diagnosis of multiple myeloma: a systematic review.

Background: Multiple myeloma is a malignant tumour of the blood in which abnormal proliferation of plasma cells leads to bone destruction, renal impairment, anaemia, and hypercalcaemia. Renal impairment caused by multiple myeloma is a common and serious condition; however, the prognosis of multiple myeloma at the time of diagnosis remains unclear.

Method: We conducted searches for literature in PubMed, Web of Science, Cochrane, Embase, CNKI, Wanfang, and VIP databases up to 30 April 2023.

In-situ amino-functionalized and reduced graphene oxide/polyimide composite films for high-performance triboelectric nanogenerator.

As a promising sustainable power source in intelligent electronics, Triboelectric Nanogenerators (TENGs) have garnered widespread interest, with various strategies explored to enhance their output performance. However, most optimization methods for triboelectric materials have focused solely on tuning chemical compositions or fabricating surface microstructures. Here, we have prepared amino-functionalized reduced graphene oxide (FRGO)/polyimide (PI) composite films (PI-FRGO) via in-situ polymerization, aimed at enhancing PI materials' nanotribological power generation performance.

Causal relationship between infection and IgA nephropathy: a bidirectional two-sample mendelian randomization study.

IgA nephropathy (IgAN) is one of the most common primary glomerulonephritis, and serum () antibody levels are increased in patients with IgA N, but the role of infection in the pathogenesis of IgAN is unclear. In this study, we investigated whether there is a causal relationship and reverse causality between IgAN and infection by using a bidirectional two-sample Mendelian randomization (MR) analysis. This study was estimated using inverse variance weighted (IVW), MR-Egger and weighted median methods, with the IVW method having the strongest statistical efficacy.

An Unusual Ferryl Intermediate and Its Implications for the Mechanism of Oxacyclization by the Loline-Producing Iron(II)- and 2-Oxoglutarate-Dependent Oxygenase, LolO.

-Acetylnorloline synthase (LolO) is one of several iron(II)- and 2-oxoglutarate-dependent (Fe/2OG) oxygenases that catalyze sequential reactions of different types in the biosynthesis of valuable natural products. LolO hydroxylates C2 of 1--acetamidopyrrolizidine before coupling the C2-bonded oxygen to C7 to form the tricyclic loline core. Each reaction requires cleavage of a C-H bond by an oxoiron(IV) (ferryl) intermediate; however, different carbons are targeted, and the carbon radicals have different fates.
