A Self-Calibrating Chemiluminescence Sensor for Rapid and Precise Antibiotic Prescribing Guidelines on Urinary Tract Infections.

Traditional antimicrobial-susceptibility testing methodologies, including the isolation and culture of bacteria from urine samples and antibiotic-susceptibility test (AST), are expensive and time-consuming. Therefore, a rapid, user-friendly phenotypic AST is urgently needed to guide treatment strategies. Several novel phenotypic AST platforms based on the physiological characteristics of bacteria obtained directly from clinical urine samples have been proposed as promising methods as rapid AST and appropriate antibiotic treatments.

Carbenium-Based Cationic Ring-Opening Polymerization of CO-Based Disubstituted δ-Valerolactone.

The challenging ring-opening homopolymerization of α-ethylidene-δ-vinyl-δ-valerolactone (EVL), derived from CO and 1,3-butadiene, has aroused extensive attention in consideration of economic efficiency and functionalization potential. In the contribution, we achieve the first cationic ring-opening polymerization (CROP) of EVL through a carbenium-based mechanism, yielding well-defined cyclic polyester PEVL with a number-average molecular weight () up to 12.8 kg/mol and a low dispersity of 1.

Economic burden of chronic obstructive pulmonary disease and post-tuberculosis sequelae in low- and middle-income countries: a database compiled from a systematic review and meta-analysis.

Background: Chronic obstructive pulmonary disease (COPD) and tuberculosis (TB) impose a substantial economic burden globally. This systematic review summarised the evidence on the costs of COPD, including post-TB diseases in low- and middle-income countries.

Methods: A systematic review was conducted and studies published between 1 January 2013 and 28 March 2022 (the date of the search) were identified using various electronic databases without language restrictions.

Transcriptome Analysis Revealed the Regulatory Mechanism of DIMBOA Affecting Early Somatic Embryogenesis in Lour.

Lour. is an evergreen tree of the genus Longan in the Sapindaceae family, native to tropical and subtropical regions. Longan embryonic development is closely related to fruit set and fruit quality.

Role of Metformin in Preventing New-Onset Chronic Kidney Disease in Patients with Type 2 Diabetes Mellitus.

: Recent evidence supports the protective role of metformin on kidney function in patients with type 2 diabetes mellitus. However, its potential to prevent new-onset chronic kidney disease (CKD) in patients with type 2 diabetes mellitus with normal renal function remains unclear. Therefore, this study aimed to investigate whether metformin could prevent the development of new-onset CKD in such patients.

Bacterial extracellular vesicles in the initiation, progression and treatment of atherosclerosis.

Atherosclerosis is the primary cause of cardiovascular and cerebrovascular diseases. However, current anti-atherosclerosis drugs have shown conflicting therapeutic outcomes, thereby spurring the search for novel and effective treatments. Recent research indicates the crucial involvement of oral and gastrointestinal microbiota in atherosclerosis.

UGP2, a novel target gene of TP53, inhibits endothelial cells apoptosis and atherosclerosis.

The dysfunction of the endothelial lining in lesion-prone areas of the arterial vasculature significantly contributes to the pathobiology of atherosclerotic cardiovascular disease. Recent studies suggested that UDP-glucose pyrophosphorylase 2 (UGP2) plays a role in cell proliferation and survival. This study investigates the anti-apoptotic and anti-atherogenic effects of UGP2 both in vitro and in vivo.

Reverse Mutations in Pigmentation Induced by Sodium Azide in the IR64 Rice Variety.

Pigmentation in rice is due mainly to the accumulation of anthocyanins. Five color mutant lines, AZ1701, AZ1702, AZ1711, AZ1714, and AZ1715, derived from the sodium azide mutagenesis on the non-pigmented IR64 variety, were applied to study inheritance modes and genes for pigmentation. The mutant line AZ1711, when crossed with IR64, displays pigmentation in various tissues, exhibiting a 3:1 pigmented to non-pigmented ratio in the F progeny, indicating a single dominant locus controlling pigmentation.

RRM2 inhibition alters cell cycle through ATM/Rb/E2F1 pathway in atypical teratoid rhabdoid tumor.

Background: Atypical teratoid rhabdoid tumor (ATRT) is an aggressive brain tumor that mainly affects young children. Our recent study reported a promising therapeutic strategy to trigger DNA damage, impede homologous recombination repair, and induce apoptosis in ATRT cells by targeting ribonucleotide reductase regulatory subunit M2 (RRM2). COH29, an inhibitor of RRM2, effectively reduced tumor growth and prolonged survival in vivo.

Inhibitory fear memory engram in the mouse central lateral amygdala.

Engrams, which are cellular substrates of memory traces, have been identified in various brain areas, including the amygdala. While most identified engrams are composed of excitatory, glutamatergic neurons, GABAergic inhibitory engrams have been relatively overlooked. Here, we report the identification of an inhibitory engram in the central lateral amygdala (CeL), a key area for auditory fear conditioning.

Transcriptomic Analysis Reveals the Flavonoid Biosynthesis Pathway Involved in Rhizome Development in Hua.

Hua () rhizomes are rich in flavonoids and other secondary metabolites, exhibiting remarkable antioxidant, anti-tumor, and immunomodulatory effects. flavonoid-biosynthesis-related genes have been characterized already. However, a comprehensive overview of flavonoid biosynthesis pathways is still absent.

LOXL1-AS1 contributes to metastasis in sonic-hedgehog medulloblastoma by promoting cancer stem-like phenotypes.

Background: Medulloblastomas (MBs) are one of the most common malignant brain tumor types in children. MB prognosis, despite improvement in recent years, still depends on clinical and biological risk factors. Metastasis is the leading cause of MB-related deaths, which highlights an unmet need for risk stratification and targeted therapy to improve clinical outcomes.

GATAD2B is required for pre-implantation embryonic development by regulating zygotic genome activation.

Major zygotic genome activation (ZGA) occurs at the late 2-cell stage and involves the activation of thousands of genes, supporting early embryonic development. The reasons underlying the regulation of ZGA are not clear. Acetylation modifications of histone tails promote transcriptional activation, and the maternal deletion of H4K16ac leads to failure in ZGA.

Functional and Transcriptome Analysis Reveal Specific Roles of and in Root Hair Development, Reproductive Growth, and Stress Tolerance.

Ran GTPases play essential roles in plant growth and development. Our previous studies revealed the nuclear localization of DlRan3A and DlRan3B proteins and proposed their functional redundancy and distinction in somatic embryogenesis, hormone, and abiotic stress responses. To further explore the possible roles of and , gene expression analysis by qPCR showed that their transcripts were both more abundant in the early embryo and pulp in longan.

Role of Peritoneal Equilibration Test in Assessing Folate Transport During Peritoneal Dialysis.

Objectives: Low plasma folate levels have been reported in patients undergoing hemodialysis and peritoneal dialysis (PD) in clinical studies. However, folate transport has never been mentioned as a factor contributing to low plasma folate levels in patients undergoing PD. The peritoneal equilibrium test (PET) assesses the plasma creatinine level and glucose transport abilities.

The miR166 targets CsHDZ3 genes to negatively regulate drought tolerance in tea plant (Camellia sinensis).

Drought is the stressor with a significant adverse impact on the yield stability of tea plants. HD-ZIP III transcription factors (TFs) play important regulatory roles in plant growth, development, and stress responses. However, whether and how HD-ZIP III TFs are involved in drought response and tolerance in tea plants remains unclear.

[Identification of banana gene family members and their expression profiles under biotic and abiotic stresses].

The Spt-Ada-Gcn5-acetyltransferase (SAGA) is an ancillary transcription initiation complex which is highly conserved. The ADA1 (alteration/deficiency in activation 1, also called histone H2A functional interactor 1, HFI1) is a subunit in the core module of the SAGA protein complex. ADA1 plays an important role in plant growth and development as well as stress resistance.
