The advent of clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9-based genome editing has marked a significant advancement in genetic engineering technology. However, the editing of induced pluripotent stem cells (iPSCs) with CRISPR presents notable challenges in ensuring cell survival and achieving high editing efficiency. These challenges become even more complex when considering the specific target site.

Background: Interhospital transfer (IHT) for acute pulmonary embolism (PE) is increasingly performed to improve access to advanced reperfusion therapies. It is unclear if outcomes of patients undergoing IHT are comparable with those of patients presenting in-house to hospitals with PE Response Team (PERT) capabilities.

Objectives: To determine whether outcomes of patients with acute PE undergoing IHT differ from those of patients presenting in-house.

The expanding field of site-specific ligation of proteins and peptides has catalyzed the development of novel methods that enhance molecular modification. Among these methods, enzymatic strategies have emerged as dominant due to their specificity and efficiency in modifying proteins under mild conditions. Asparaginyl endopeptidase is a group of cyclotide-producing cysteine proteases from plants.

To understand how particular post-translational modifications (PTMs) affect the function of a target protein, it is essential to first prepare and investigate the target with the modification at the desired position. This drives the continuous development of site-specific protein modification technologies. Here, we present the chemical synthesis and application of the biarsenical linker SrtCrAsH-EDT, which has a dual labeling functionality.

Interleukin-8 (IL8) is an important cytokine that plays a significant role in tumor growth and angiogenesis across various malignant tumors, including oral squamous cell carcinoma (OSCC). It is an important biomarker for oral cancer; therefore, its early and accurate detection in bodily fluid reduces morbidity and mortality rates in cancer patients. The work presents the development of a label-free microfluidic miniaturized electrochemical immunosensor for IL8 biomarker detection at low concentration in saliva samples.

Article Synopsis
  • Hypertensive disorders of pregnancy (HDP) are major factors contributing to complications for both mothers and babies, and higher serum uric acid levels may indicate the severity of these conditions.
  • A study involving 134 pregnant women with high blood pressure found that those with conditions like preeclampsia and eclampsia had significantly higher mean uric acid levels, suggesting a correlation between uric acid and illness severity.
  • Elevated uric acid levels were associated with increased risks for ICU admission, preterm delivery, and low-birth-weight babies, highlighting its potential use in assessing health risks in pregnant women with HDP.

  • - Lymphoepithelial carcinoma (LEC) of salivary glands is a rare and slowly growing tumour that typically appears as a painless mass.
  • - Properly distinguishing LEC from other cancers, like secondary tumours or nasopharyngeal carcinoma, is crucial for determining the right treatment plan.
  • - A case study highlighted an elderly male with a parotid gland swelling, which was diagnosed as LEC through fine needle aspiration cytology and further confirmed by histopathology and immunohistochemistry.

Background Therapeutic anticoagulation is the cornerstone of treatment for pulmonary embolism (PE), but the impact of different anticoagulation strategies on patient outcomes remains unclear. In this study, we assessed the association of different anticoagulation strategies with the outcomes of patients with acute PE. Methods A retrospective chart review of 207 patients with acute PE who were admitted to one of three urban teaching hospitals in the Mount Sinai Health System (in New York City) from January 2020 to September 2022 was performed.

A recent development in deep learning techniques has attracted attention to the decoding and classification of electroencephalogram (EEG) signals. Despite several efforts to utilize different features in EEG signals, a significant research challenge is using time-dependent features in combination with local and global features. Several attempts have been made to remodel the deep learning convolution neural networks (CNNs) to capture time-dependency information.

Objective: Characterisation of oxygen saturation (SpO)-related predictors that correspond with both bronchopulmonary dysplasia-associated pulmonary hypertension (BPD-PH) development and survival status in infants with BPD-PH may improve patient outcomes. This investigation assessed whether (1) infants with BPD-PH compared with infants with BPD alone, and (2) BPD-PH non-survivors compared with BPD-PH survivors would (a) achieve lower SpO distributions, (b) have a higher fraction of inspired oxygen (FiO) exposure and (c) have a higher oxygen saturation index (OSI).

Design: Case-control study between infants with BPD-PH (cases) and BPD alone (controls) and by survival status within cases.

Centrin1 gene deleted Leishmania donovani parasite (LdCen1) was developed and extensively tested experimentally as an intracellular stage-specific attenuated and immunoprotective live parasite vaccine candidate ex vivo using human PBMCs and in vivo in animals. Here we report manufacturing and pre-clinical evaluation of current Good-Laboratory Practice (cGLP) grade LdCen1 parasites, as a prerequisite before proceeding with clinical trials. We screened three batches of LdCen1 parasites manufactured in bioreactors under cGLP conditions, for their consistency in genetic stability, attenuation, and safety.

Article Synopsis
  • Atoms form the building blocks of nature, and their arrangement into molecules can create new technologies when matter interacts with light under strong coupling conditions.
  • Achieving strong coupling, especially at terahertz frequencies, is challenging due to the need for precise confinement of the optical field.
  • This study presents methods for confining electromagnetic fields that enhance light-matter interactions, achieving significant results like a 200 GHz vacuum Rabi splitting with glucose, which could advance the design of systems that leverage hybrid light-matter states.

The use of genetic engineering to generate point mutations in induced pluripotent stem cells (iPSCs) is essential for studying a specific genetic effect in an isogenic background. We demonstrate that a combination of p53 inhibition and pro-survival small molecules achieves a homologous recombination rate higher than 90% using Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) in human iPSCs. Our protocol reduces the effort and time required to create isogenic lines.
