A rare case of prostatic malakoplakia with multidrug-resistant Escherichia coli: a case report.

Prostatic malakoplakia is an uncommon chronic inflammatory disorder, tumor-like but non-cancerous, the diagnosis of which pivots crucially on the identification of characteristic Michaelis-Gutmann bodies within the pathological tissue. We hereby present an inaugural case report of prostatic malakoplakia concurrent with sepsis caused by multidrug-resistant Escherichia coli, verified through blood culture and metagenomic next-generation sequencing (mNGS). The pathogenesis might be associated with infections by Escherichia coli, immune system irregularities, or lysosomal dysfunction.

A novel approach for anterior cruciate ligament tibial avulsion fracture: arthroscopic modified suture bridge fixation technique.

Introduction: Anterior cruciate ligament (ACL) tibial avulsion fracture is a rare injury, which usually happens in adults with traffic accidents or sports injuries. Surgery interventions are common treatment methods, they can restore knee function and help to return to normal life. In this study, we described an arthroscopic modified suture bridge fixation technique for ACL tibial avulsion fractures and explored the feasibility and therapeutic effects.

Two novel zinc-based MOFs as luminescence sensors to detect phenylglyoxylic acid.

Automobile exhaust gases, plastic pollutants, smoking, and other harmful substances can cause serious harm to human beings and the environment. Styrene, as a common airborne toxin, enters the human body through breathing or the skin and is discharged in the form of phenylglyoxylic acid (PGA). Therefore, specific, sensitive and trace detection of PGA is particularly important.

Brainstem atrophy in the early stage of Alzheimer's disease: a voxel-based morphometry study.

Postmortem studies on patients with Alzheimer's disease (AD) have confirmed that the dorsal raphe nucleus (DRN) in the brainstem is the first brain structure affected in the earliest stage of AD. The present study examined the brainstem in the early stage of AD using magnetic resonance (MR) imaging. T1-weighted MR images of the brains of 81 subjects were obtained from the publicly available Open Access Series of Imaging Studies (OASIS) database, including 27 normal control (NC) subjects, 27 patients with very mild AD (AD-VM) and 27 patients with mild AD (AD-M).

Tetrel bonding interaction: an analysis with the block-localized wavefunction (BLW) approach.

In this study, fifty-one iconic tetrel bonding complexes were studied using the block localized wave function (BLW) method which can derive the self-consistent wavefunction for an electron-localized (diabatic) state where charge transfer is strictly deactivated. Energy decompositions based on the BLW method (BLW-ED in short) show that the frozen energy, which is mostly composed of the Pauli repulsion and electrostatic components, plays the dominating role in thirty-one out of these fifty-one systems. A further quantitative study of electrostatic potential (ESP) was carried out by analyzing the variation of ESP along the binding direction for each monomer.

Goat and buffalo milk fat globule membranes exhibit better effects at inducing apoptosis and reduction the viability of HT-29 cells.

Bovine milk fat globule membrane (MFGM) has shown many health benefits, however, there has not been much study on non-cattle MFGMs. The purpose of this study was to compare the anti-proliferation effects and investigate the mechanisms of MFGMs from bovine, goat, buffalo, yak and camel milk in HT-29 cells. Results showed that protein content in MFGM of yak milk is the highest among five MFGM.

Surgical exposures of the distal humeral fractures: An anatomical study of the anterior, posterior, medial and lateral approaches.

Purpose: Exposure of the articular surface is the key to the successful treatment of intra-articular fractures of distal humerus. Anterior, posterior olecranon osteotomy as well as medial and lateral approaches are the four main approaches to the elbow. The aim of this study was to compare the exposure of distal articular surfaces of these surgical approaches.

Separate neural systems for behavioral change and for emotional responses to failure during behavioral inhibition.

To analyze the involvement of different brain regions in behavioral inhibition and impulsiveness, differences in activation were investigated in fMRI data from a response inhibition task, the stop-signal task, in 1709 participants. First, areas activated more in stop-success (SS) than stop-failure (SF) included the lateral orbitofrontal cortex (OFC) extending into the inferior frontal gyrus (ventrolateral prefrontal cortex, BA 47/12), and the dorsolateral prefrontal cortex (DLPFC). Second, the anterior cingulate and anterior insula (AI) were activated more on failure trials, specifically in SF versus SS.

A statistical approach for detecting common features.

Background: With increasing numbers of datasets in neuroimaging studies, it has become an important task to pool information, in order to increase the statistical power of tests and for cross validation. However, no robust global approach unambiguously identifies the common biological abnormalities in, for example, resting-state functional magnetic resonance imaging in a number of mental disorders, where there are multiple datasets/attributes. Here we propose a novel and efficient statistical approach to this problem that finds common features in multiple datasets.
