The effect of rice and edible starch compound ratios, starch type, and rice nutrients on Burkholderia gladioli pathovar cocovenenans growth and bongkrekic acid production in wet rice noodles and starch products.

Bongkrekic acid (BA) toxin, produced by Burkholderia gladioli pathovar cocovenenans bacteria, has been implicated in foodborne illness outbreaks. BA poisoning is associated with rice noodle consumption; hence, this study investigated B. cocovenenans growth and BA production in wet rice noodles comprising varying starch ratios, starch types, rice nutrients, and saccharides.

Cancer-specific innate and adaptive immune rewiring drives resistance to PD-1 blockade in classic Hodgkin lymphoma.

Hodgkin Reed-Sternberg (HRS) cells of classic Hodgkin lymphoma (cHL), like many solid tumors, elicit ineffective immune responses. However, patients with cHL are highly responsive to PD-1 blockade, which largely depends on HRS cell-specific retention of MHC class II and implicates CD4 T cells and additional MHC class I-independent immune effectors. Here, we utilize single-cell RNA sequencing and spatial analysis to define shared circulating and microenvironmental features of the immune response to PD-1 blockade in cHL.

Synergistic inhibitory effects of tetramethylpyrazine and evodiamine on endometriosis development.

Endometriosis (EMS) belongs to a gynecological disorder with inflammation and the existence of endometrial-like tissues beyond the uterus, often leading to infertility and pelvic pain. Estrogen receptor β (ERβ) is significantly expressed in endometriosis (EMS) and recognized as a promising therapeutic target for EMS treatment by inhibiting ERβ activity. In this study, we investigated the potential mechanisms for tetramethylpyrazine (TMP)-mediated ERβ suppression, and the synergistic inhibitory effect of TMP and evodiamine (EVO) on ERβ expression and EMS development.

Microenvironment Self-Adaptive Nanomedicine Promotes Spinal Cord Repair by Suppressing Inflammation Cascade and Neural Apoptosis.

Despite various biomaterial-based strategies are tried in spinal cord injury (SCI), developing safe and effective microinvasive pharmacotherapy strategies is still an unmet clinical need. Stimuli-responsive nanomedicine has emerged as a promising non-invasion technology, which enhances drug delivery and promotes functional recovery following SCI. Considering the multiple progressive pathological events and the blood spinal cord barrier (BSCB) associating SCI, a microenvironment self-adaptive nanoparticle (custom-designed with rabies virus glycoprotein 29-RVG29 and hyaluronic acid-HA, RHNP) capable of consistently crossing the BSCB and selectively targeting inflammatory cells and neural cells based on different stages of SCI are developed.

The evolution of computational research in a data-centric world.

Salidroside promotes the repair of spinal cord injury by inhibiting astrocyte polarization, promoting neural stem cell proliferation and neuronal differentiation.

Spinal cord injury (SCI) remains a formidable challenge, lacking effective treatments. Following SCI, neural stem cells (NSCs) migrate to SCI sites, offering a potential avenue for nerve regeneration, but the effectiveness of this intrinsic repair mechanism remains suboptimal. Salidroside has demonstrated pro-repair attributes in various pathological conditions, including arthritis and cerebral ischemia, and the ability to curtail early-stage inflammation following SCI.

Advances in the Structure of GGGGCC Repeat RNA Sequence and Its Interaction with Small Molecules and Protein Partners.

The aberrant expansion of GGGGCC hexanucleotide repeats within the first intron of the gene represent the predominant genetic etiology underlying amyotrophic lateral sclerosis (ALS) and frontal temporal dementia (FTD). The transcribed r(GGGGCC) RNA repeats form RNA foci, which recruit RNA binding proteins and impede their normal cellular functions, ultimately resulting in fatal neurodegenerative disorders. Furthermore, the non-canonical translation of the r(GGGGCC) sequence can generate dipeptide repeats, which have been postulated as pathological causes.

Compensation Mechanisms May Not Always Account for Enhanced Multisensory Illusion in Older Adults: Evidence from Sound-Induced Flash Illusion.

Sound-induced flash illusion (SiFI) is typical auditory dominance phenomenon in multisensory illusion. Although a number of studies have explored the SiFI in terms of age-related effects, the reasons for the enhanced SiFI in older adults are still controversial. In the present study, older and younger adults with equal visual discrimination were selected to explore age differences in SiFI effects, and to explore the neural indicators by resting-state functional magnetic resonance imaging (rs-fMRI) signals.

A systematic literature search up to July 2022 was performed and 10 231 subjects with cervical cancer at the baseline of the studies; 4307 of them were using the minimally invasive surgery, and 5924 were using laparotomy. Odds ratio (OR) with 95% confidence intervals (CIs) were calculated to assess the effect of minimally invasive surgery and laparotomy on wound infection and postoperative and intraoperative complications in the management of cervical cancer using the dichotomous methods with a random or fixed-effect model.

Reward reduces the fission illusion in the sound-induced flash illusion.

Pairing a single visual stimulus with multiple auditory stimuli will lead to the illusory perception of multiple visual stimuli, which is known as sound-induced flash illusion (SIFI). The present study adopted the classic SIFI paradigm to investigate whether value-associated tasks could affect the SIFI. By adjusting the sequence of reward and nonreward conditions, we also examined the effect of reward history on SIFI.

Enhanced Efficacy of Simultaneous PD-1 and PD-L1 Immune Checkpoint Blockade in High-Grade Serous Ovarian Cancer.

Immune therapies have had limited efficacy in high-grade serous ovarian cancer (HGSC), as the cellular targets and mechanism(s) of action of these agents in HGSC are unknown. Here we performed immune functional and single-cell RNA sequencing transcriptional profiling on novel HGSC organoid/immune cell co-cultures treated with a unique bispecific anti-programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) antibody compared with monospecific anti-PD-1 or anti-PD-L1 controls. Comparing the functions of these agents across all immune cell types in real time identified key immune checkpoint blockade (ICB) targets that have eluded currently available monospecific therapies.

Effects of Repetition Suppression on Sound Induced Flash Illusion With Aging.

The sound-induced flash illusion (SiFI) is a classical auditory-dominated multisensory integration phenomenon in which the observer misperceives the number of visual flashes due to the simultaneous presentation of a different number of auditory beeps. Although the SiFI has been documented to correlate with perceptual sensitivity, to date there is no consensus as to how it corresponds to sensitivity with aging. The present study was based on the SiFI paradigm (Shams et al.
