COVID-19 may induce a state of hypercoagulability, particularly in critically ill patients, for reasons that remain unknown. Numerous studies have identified the presence of antiphospholipid antibodies in patients with COVID-19; however, the definitive diagnosis of antiphospholipid syndrome continues to pose challenges. Here, we present the case of a patient infected with SARS-CoV-2 who developed life-threatening severe thrombocytopenia, profound anaemia, acute pulmonary hypertension, right ventricular failure, and renal insufficiency.

We report the free energy barriers for the elementary reactions in the 2e- and 4e- oxygen reduction reaction (ORR) steps on Au(100) in an alkaline solution. Due to the weak adsorption energy of O2 on Au(100), the barrier for the association channel is very low, and the 2e- pathway is clearly favored, while the barrier for the O-O dissociation channel is significantly higher at 0.5 eV.

Background: Hyperthermia and multiple organ dysfunction syndrome (MODS) are the main characteristics of heatstroke and COVID-19. Differentiating between these illnesses is crucial during a summer COVID-19 pandemic, but cases of heatstroke comorbid with COVID-19 are rarely reported.

Case Description: We report the first case of heatstroke comorbid with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection in a 52-year-old male.

Purpose: Minimal data exist on brain injury in patients with exertional heatstroke (EHS) in developing country. In this study, we explored the risk factors for brain injury induced by EHS 90-day after onset.

Methods: A retrospective cohort study of patients with EHS was conducted in the intensive care unit of the General Hospital of Southern Theater Command of PLA in China from April 2014 to June 2019.

Purpose: The incidence of heatstroke (HS) is not particularly high; however, once it occurs, the consequences are serious. It is reported that calcitonin gene-related peptide (CGRP) is protective against brain injury in HS rats, but detailed molecular mechanisms need to be further investigated. In this study, we further explored whether CGRP inhibited neuronal apoptosis in HS rats via protein kinase A (PKA)/p-cAMP response element-binding protein (p-CREB) pathway.

Peripherally-induced neuropathic pain (pNP) is a kind of NP that is common, frequent, and difficult to treat. Tuina, also known as massage and manual therapy, has been used to treat pain in China for thousands of years. It has been clinically proven to be effective in the treatment of pNP caused by cervical spondylosis, lumbar disc herniation, etc.

Two-photon Hong-Ou-Mandel (HOM) interference is a fundamental quantum effect with no classical counterpart. The existing research on two-photon interference was mainly limited in one degree of freedom (DOF); hence, it is still a challenge to realize quantum interference in multiple DOFs. Here, we demonstrate HOM interference between two hyperentangled photons in two DOFs of polarization and orbital angular momentum (OAM) for all 16 hyperentangled Bell states.

We find that all Feynman integrals (FIs), having any number of loops, can be completely determined once linear relations between FIs are provided. Therefore, FI computation is conceptually changed to a linear algebraic problem. Examples up to five loops are given to verify this observation.

Using ab initio molecular dynamics simulations with fully solvated ions, we demonstrate that solvated OH forms a stable hydrogen bond with Au(100). Unlike the hydrogen bond between HO and Au reported previously, which is more favorable for negatively charged Au, the OH···Au interaction is stabilized when a small positive charge is added to the metal slab. For electro-catalysis, this means that while OH···Au plays a significant role in the hydrogen evolution reaction, OH···Au could be a significant factor in the oxygen reduction reaction in alkaline media.

Background: Heat stroke is a potentially fatal condition that is caused by elevated core temperature. Guillain-Barré syndrome (GBS) induced by heat stroke is extremely rare and has only been reported in few case reports. The purpose of this case study was to evaluate the clinical symptoms, neuroelectrophysiological and imageological features of GBS after heat stroke.

Objectives: To investigate the influencing factors for the quality of bowel preparation before colonoscopy in children and the association of the interval from the last administration of laxative to the start of colonoscopy (shortly referred to as waiting time) with the quality of bowel preparation.

Methods: A retrospective analysis was performed for the children who were admitted to the Department of Gastroenterology, Children's Hospital of Nanjing Medical University, from January to November 2020, and received bowel preparation with polyethylene glycol electrolyte powder combined with diet control before colonoscopy. According to the score of Boston bowel preparation scale, they were divided into two groups: adequate bowel preparation group (=337) and inadequate bowel preparation group (=30).

Background: Secreted protein acidic and rich in cysteine-like 1 (SPARCL1) plays an important role in tumor pathogenesis. We aim to evaluate the clinical significance and potential biological roles of SPARCL1 in colorectal cancer (CRC).

Methods: Datasets from the Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases were downloaded to evaluate the expression levels of SPARCL1 in CRC.

Article Synopsis
  • The article examines the clinical characteristics and prognosis of patients with COVID-19-associated sepsis compared to those with classic bacterial sepsis, specifically focusing on carbapenem-resistant Klebsiella pneumonia.
  • It highlights the more severe lung injury and milder systemic inflammatory response in COVID-19 patients, along with a greater reliance on corticosteroid therapy and ECMO for treatment.
  • The study finds that while COVID-19 patients had worse immunosuppression, they also had better organ functions and lower critical illness scores compared to those with bacterial sepsis.

Hydroxide ion is a common electrolyte when electrode reactions take place in alkaline media. In the case of oxygen reduction reaction on Pt(111), we demonstrate by ab initio molecular dynamics calculations that the desorption of hydroxyl (OH*) from the electrode surface to form a solvated OH is a cross-sphere process, with the OH* reactant in the inner sphere and the OH product directly generated in the aqueous outer sphere. Such a mechanism is distinct from the typical inner sphere and outer sphere reactions.

Microbial oligosaccharides have been regarded as one of the most appealing natural products attributable to their potent and selective bioactivities, such as antimicrobial activity, inhibition of α-glucosidases and lipase, interference of cellular recognition and signal transduction, and disruption of cell wall biosynthesis. Accordingly, a handful of bioactive oligosaccharides have been developed for the treatment of bacterial infections and type II diabetes mellitus. Given that naturally occurring oligosaccharides have increasingly gained recognition in recent years, a comprehensive review is needed.

  • *Mouse experiments revealed that higher doses of laver did not significantly raise arsenate (As(V)) levels in tissues or feces, but dimethylarsinic acid (DMA(V)) showed a strong correlation with the amount of laver consumed.
  • *Most arsenic from laver was expelled through feces, with only a tiny fraction accumulating in mouse organs, highlighting that the metabolic behavior of arsenic species in laver is important for assessing health risks.
