The method described by Czosnyka is particularly suitable for measuring CPPe in patients undergoing cerebral angiography.

Background: The primary objective of this study was to estimate the effective cerebral perfusion pressure (CPPe), critical closing pressure (CrCP), and resistance-area product (RAP) of the intravascular common carotid artery using three different methods. These estimates were then compared to the reference method of linear regression (LR).

Methods: In our previous study, we employed linear regression to evaluate the values of CrCP and RAP.

Global diversity and ecological functions of viruses inhabiting oil reservoirs.

Oil reservoirs, being one of the significant subsurface repositories of energy and carbon, host diverse microbial communities affecting energy production and carbon emissions. Viruses play crucial roles in the ecology of microbiomes, however, their distribution and ecological significance in oil reservoirs remain undetermined. Here, we assemble a catalogue encompassing viral and prokaryotic genomes sourced from oil reservoirs.

A large-scale dataset for end-to-end table recognition in the wild.

Table recognition (TR) is one of the research hotspots in pattern recognition, which aims to extract information from tables in an image. Common table recognition tasks include table detection (TD), table structure recognition (TSR) and table content recognition (TCR). TD is to locate tables in the image, TCR recognizes text content, and TSR recognizes spatial & ontology (logical) structure.

A novel temperate phage, vB_PstS-pAN, induced from the naphthalene-degrading bacterium Pseudomonas stutzeri AN10.

A novel temperate phage named vB_PstS-pAN was induced by mitomycin C treatment from the naphthalene-degrading bacterium Pseudomonas stutzeri AN10. The phage particles have icosahedral heads and long non-contractile tails, and vB_PstS-pAN can therefore be morphologically classified as a member of the family Siphoviridae. The whole genome of vB_PstS-pAN is 39,466 bp in length, with an 11-nt 3' overhang cohesive end.

Isolation Chip Increases Culturable Bacterial Diversity and Reduces Cultivation Bias.

Conventional cultivation methods, including petri dish plating, are selective and biased to enrich specific microorganisms, such as big population and fast-growing bacteria. In this study, we evaluated the ability of isolation chip (ichip) to reduce cultivation bias. We used the ichip and petri dish plating methods to cultivate bacteria from soil contaminated with (contaminated soil) or without (natural soil) crude oil.

Isolation and characterization of the novel Pseudomonas stutzeri bacteriophage 8P.

Bacteriophage 8P was isolated with a Pseudomonas stutzeri strain isolated from an oil reservoir as its host bacterium. The phage genome comprises 63,753 base pairs with a G+C content of 64.35.

Complete genome sequence of a novel Bacillus phage, P59, that infects Bacillus oceanisediminis.

P59, a virulent phage of Bacillus oceanisediminis, was isolated from the sediment of Weiming Lake at Peking University (Beijing, China). P59 showed the typical morphology of myovirids. The complete genome sequence of P59 is 159,363 bp in length with a G+C content of 42.

Cerebral Microbleeds Are Associated With Mild Cognitive Impairment in Patients With Hypertension.

Background: Cerebral microbleeds (CMBs) are hypothesized downstream markers of brain damage caused by vascular and amyloid pathologic mechanisms. The aim of this study was to determine whether CMB count and location are associated with an increased risk for mild cognitive impairment (MCI) in patients with essential hypertension without a history of transient ischemic attack or stroke.

Methods And Results: In this cross-sectional study, patients were prospectively enrolled from consecutive outpatients with essential hypertension 50 years and older at 3 centers in northern China.

NLRP6 Inflammasome Ameliorates Brain Injury after Intracerebral Hemorrhage.

NLRP6 inflammasome, one of the important intracellular innate immune sensors, has been shown to regulate immune responses. However, its roles in the intracerebral hemorrhage (ICH) are completely not clear. In the present study, we investigated the expression profile and biological roles of NLRP6 inflammasome in perihematomal brain tissues of mice subjected to ICH.

Association between platelet function and recurrent ischemic vascular events after TIA and minor stroke .

Platelet activation and aggregation play an important role in the pathological and physiological processes of recurrent ischemic vascular events in stroke patients. The purpose of this study is to determine the association between platelet function measured in the acute period and recurrent ischemic vascular events in patients with transient ischemic attack (TIA) or minor stroke. A total of 417 patients who were within the 24-hour period of clopidogrel-aspirin therapy after onset of a minor stroke or high-risk transient ischemic attack according to the Clopidogrel in High-risk patients with Acute Nondisabling Cerebrovascular Events (CHANCE) trial were included in this study.
