BACKGROUND: Early discontinuation of total parenteral nutrition (TPN) at 100 ml/kg/day of enteral feeds, compared with 140 ml/kg/day, led to significant delay in time to regain the birth weight in very low birth weight infants (birth weight < 1500 g, VLBW). Our aim was to compare the growth of infants in relation with timing of TPN discontinuation up to 2 years corrected gestational age (CGA). METHODS: Posttrial follow-up study using review of paper medical records...

CGA-N12 is an antimicrobial peptide derived from the N-terminus of human chromogranin A and comprises the 65th to the 76th amino acids. Our previous studies showed that CGA-N12 reduces Candida tropicalis mitochondrial membrane potential. Here, we explored the mechanism that CGA-N12 collapsed the mitochondrial membrane potential by investigations of its action on the mitochondrial permeability transition pore (mPTP) complex of C. tropicalis. The results showed that CGA-N12 induced Cyt c leakage, mitochondria swelling and led to PEG of molecular weight 1000 Da penetrate mitochondria...

Bidens pilosa is an edible herb from the Asteraceae family which is traditionally consumed as a leafy vegetable. B. pilosa has many bioactivities owing to its diverse phytochemicals, which include aliphatics, terpenoids, tannins, alkaloids, hydroxycinnamic acid (HCA) derivatives and other phenylpropanoids. The later include compounds such as chlorogenic acids (CGAs), which are produced as either regio - or geometrical isomers. To profile the CGA composition of B. pilosa , methanol extracts from tissues, callus and cell suspensions were utilized for liquid chromatography coupled to mass spectrometric detection (UHPLC-QTOF-MS/MS)...

Objective : The incidence of enteropancreatic neuroendocrine tumours (NET) is increasing. Chromogranin A (CgA) in plasma is a marker in patients suspected of NET tumours. CgA, however, is a precursor protein subjected to cellular processing that challenges quantitation and hence the use of CgA in diagnostics. Materials and methods : CgA concentrations in plasma sampled from 130 well-characterized patients with small intestinal NETs and from 30 healthy subjects were measured with eight commercial CgA kits, an in-house radioimmunoassay (RIA) and a processing-independent assay (PIA)...

OBJECTIVES: Recently developed CRISPR-dependent cytosine base editor (CBE), converting four codons (CAA, CAG, CGA and TGG) into stop codons without DNA double-strand breaks (DSB), serves as an efficient gene disruption strategy besides uncontrollable CRISPR-mediated frameshift. However, the detailed difference of gene knockout between the two systems has not been clarified. MATERIALS AND METHODS: Here, we selected some sgRNAs with different position background, then HEK293T cells were transfected with CBE/Cas9 plasmids together with sgRNAs...

The antimicrobial peptide CGA-N12 (NH2-ALQGAKERAHQQ-COOH) is an active peptide derived from chromogranin A (CGA) and consists of the 65th to 76th amino acids of the N-terminus. The results of our previous studies showed that CGA-N12 exerts anti-Candida activity by inducing apoptosis without destroying the integrity of cell membranes. In this study, the effect of CGA-N12 on the cell membrane structure of Candida tropicalis was investigated. CGA-N12 resulted in the dissipation of the membrane potential, the increase in membrane fluidity, and the outflow of potassium ions in C...

BACKGROUND: Enterochromaffin-like (ECL) cells in the stomach express gastrin/CCK2 receptors and are known to expand under hypergastrinemia, but whether this results from expansion of existing ECL cells or increased production from progenitors has not been clarified. METHODS: We utilized mice with fluorescent reporter expression in ECL cells (Hdc-GFP) as well as Cck2r-CreERT2 and Hdc-CreERT2 mice combined with R26-tdTomato mice, and studied their expression and cell fate in the gastric corpus by using models of hypergastrinemia (gastrin infusion, omeprazole treatment)...

Extracellular accumulation of amyloid beta peptide (Aβ) is believed to be one of the main factors responsible for neurodegeneration in Alzheimer's disease (AD). Metals could induce Aβ aggregation, by their redox activity or binding properties to amyloid β fibrils, leading to their accumulation and deposition outside neurons. For this reason, metal chelation may have an acknowledged part to play in AD prevention and treatment. In the current work, the role of different selenium species, including selenium nanoparticles, in Aβ aggregation, was studied by evaluating their metal-chelating properties and their ability both to inhibit metal-induced Aβ1-42 aggregation fibrils and to disaggregate them once formed...

Completing comprehensive geriatric assessments (CGA) for frail patients admitted to acute hospitals has well-established benefits and is advocated by national guidelines. There is high-quality evidence demonstrating an association between inpatient CGAs and the patient being alive and community-dwelling at 12-month follow-up. However, less well-known is the effectiveness of CGAs conducted within the emergency department (ED), with the primary purpose of facilitating admission avoidance, on reducing 30-day reattendance or readmission...

Background: Frailty is characterized by loss of biological reserves and is associated with an increased risk of adverse health outcomes. Frailty can be operationalized using a Frailty Index (FI) based on the accumulation of health deficits; items under health evaluation in the well-established Comprehensive Geriatric Assessment (CGA) have been used to generate an FI-CGA. Traditionally, constructing the FI-CGA has relied on paper-based recording and manual data processing. As this can be time-consuming and error-prone, it limits widespread uptake of this proven type of frailty assessment...
