With over two millennia of history, traditional Chinese acupuncture ranks among the most renowned forms of supplementary and other healthcare. The use of acupuncture releases endorphins and serotonin, two naturally occurring painkillers, into the nervous system and stimulates it. It also modifies how pain signals are processed and perceived.

Liquid-like protein condensates are ubiquitous in cellular system and are increasingly recognized for their roles in physiological processes. Condensed phase harbors distinctive chemical microenvironment, markedly different than dilute aqueous phase. Herein, we demonstrate chemoselective modification pattern of nucleophilic canonical amino acid sidechains (namely - cysteine, tyrosine and lysine) of the protein towards 4-chloro-7-nitrobenzofurazan in the dilute and condensed phase.

Article Synopsis
  • The study investigates the outcomes of gallbladder cancer (GBC) patients with retroperitoneal lymphadenopathy (RPLN), analyzing their response to treatment via chemotherapy followed by consolidation chemoradiotherapy (CTRT).
  • It focuses on a group of 189 patients, of which 80 had RPLN, comparing their treatment responses and overall survival rates to those without RPLN, noting their similar demographic characteristics.
  • Results indicated that while both groups had comparable response rates to treatment, overall survival was further analyzed using statistical methods, highlighting a complex treatment dilemma for patients with RPLN in locally advanced non-metastatic GBC.

Antimicrobial resistance (AMR) has become one of the most serious threats to One Health. Aquatic environments are an ideal non-clinical AMR reservoir and can act as a key battlefront for tackling the AMR. However, AMR data using the One Health approach remain scarce in aquatic environments worldwide.

Motorized two-wheeler users account for 45% of road fatalities in 2021 in India. Correct helmet use decreases the risk of fatalities, but information about the prevalence of correct helmet use is limited in the Indian context. This study aims to assess the prevalence of helmet use and factors associated with correct helmet use among motorized two-wheeler users in Bengaluru city, India.

Microorganisms are shown to actively partition their intracellular resources, such as proteins, for growth optimization. Recent experiments have begun to reveal molecular components unpinning the partition; however, quantitatively, it remains unclear how individual parts orchestrate to yield precise resource allocation that is both robust and dynamic. Here, we developed a coarse-grained mathematical framework that centers on guanosine pentaphosphate (ppGpp)-mediated regulation and used it to systematically uncover the design principles of proteome allocation in .

Because most DNA-binding transcription factors (dbTFs), including the architectural regulator CTCF, bind RNA and exhibit di-/multimerization, a central conundrum is whether these distinct properties are regulated post-transcriptionally to modulate transcriptional programs. Here, investigating stress-dependent activation of encoding an evolutionarily-conserved protein deacetylase, we show that induced phosphorylation of CTCF acts as a rheostat to permit CTCF occupancy of low-affinity promoter DNA sites to precisely the levels necessary. This CTCF recruitment to the SIRT1 promoter is eliciting a cardioprotective cardiomyocyte transcriptional activation program and provides resilience against the stress of the beating heart .

Homeodomain-interacting protein kinase 1 (HIPK1) is majorly found in the nucleoplasm. HIPK1 is associated with cell proliferation, tumor necrosis factor-mediated cellular apoptosis, transcription regulation, and DNA damage response, and thought to play significant roles in health and common diseases such as cancer. Despite this, HIPK1 remains an understudied molecular target.

Thousand and one amino acid kinase 1 (TAOK1) is a sterile 20 family Serine/Threonine kinase linked to microtubule dynamics, checkpoint signaling, DNA damage response, and neurological functions. Molecular-level alterations of TAOK1 have been associated with neurodevelopment disorders and cancers. Despite their known involvement in physiological and pathophysiological processes, and as a core member of the hippo signaling pathway, the phosphoregulatory network of TAOK1 has not been visualized.

Background: Sepsis is the most common cause of acute kidney injury (AKI) in critically ill patients. Four phenotypes (α, β, γ, δ) for sepsis, which have different outcomes and responses to treatment, were described using routine clinical data in the electronic health record.

Research Question: Do the frequencies of AKI, acute kidney disease (AKD), chronic kidney disease (CKD), and AKI on CKD differ by sepsis phenotype?

Study Design And Methods: This was a secondary analysis of a randomized clinical trial of early resuscitation, including patients with septic shock at 31 sites.

The structure of nucleons is multidimensional and depends on the transverse momenta, spatial geometry, and polarization of the constituent partons. Such a structure can be studied using high-energy photons produced in ultraperipheral heavy-ion collisions. The first measurement of the azimuthal angular correlations of exclusively produced events with two jets in photon-lead interactions at large momentum transfer is presented, a process that is considered to be sensitive to the underlying nuclear gluon polarization.

Production cross sections of the standard model Higgs boson decaying to a pair of W bosons are measured in proton-proton collisions at a center-of-mass energy of 13. The analysis targets Higgs bosons produced via gluon fusion, vector boson fusion, and in association with a W or Z boson. Candidate events are required to have at least two charged leptons and moderate missing transverse momentum, targeting events with at least one leptonically decaying W boson originating from the Higgs boson.

New sets of parameter tunes for two of the colour reconnection models, quantum chromodynamics-inspired and gluon-move, implemented in the pythia  8 event generator, are obtained based on the default CMS pythia  8 underlying-event tune, CP5. Measurements sensitive to the underlying event performed by the CMS experiment at centre-of-mass energies and 13, and by the CDF experiment at 1.96 are used to constrain the parameters of colour reconnection models and multiple-parton interactions simultaneously.
