In eukaryotes, chromatin is compacted within nuclei under the principle of compartmentalization. On top of that, condensin II establishes eukaryotic chromosome territories, while cohesin organizes the vertebrate genome by extruding chromatin loops and forming topologically associating domains (TADs). Thus far, the formation and roles of these chromatin structures in plants remain poorly understood.

Mesoderm-specific transcript (MEST) is a tumor-promoting factor that regulates multiple oncogenic signaling pathways. However, the role of MEST-mediated immune escape is unclear.

The aim of the present study was to provide a detailed definition of the range of SCLN regions and to explore whether SCLNs should be considered as a regional lymph nodes for patients with cervical and upper thoracic ESCC. A retrospective analysis was performed on 230 patients with locally advanced cervical or upper thoracic ESCC who underwent radical radiotherapy and chemotherapy.

The utilisation of robotic assistance has the potential to enhance the feasibility of performing minimally invasive pancreaticoduodenectomy in this particular group of patients who are at a higher risk. The objective of this meta-analysis is to assess the safety and effectiveness of robotic pancreaticoduodenectomy in individuals with overweight or obesity.

Therefore, in this study, we were interested in the impact of exosomal miR-196a-5p in ESCC progression. We found that miR-196a-5p was expressed enriched in clinical tissues, ESCC cells, and exosomes.

Methods: Patients (n=104) with anterior circulation Alberta Stroke Program Early Computed Tomography Score <6 were screened for infarct volume ≥150 mL using the Pullicino formula × (1-22%). The following were compared with the baseline at 90 days: the modified Rankin scale score (mRS) ≤3, mortality rate, symptomatic intracranial hemorrhage and any intracranial hemorrhage within 48 hours, and modified Thrombolysis in Cerebral Infarction (mTICI) ≥2b between the EVT and drug therapy (DT) groups.
Four randomized controlled trials of large infarct core volume (LICV) included three imaging modalities: non-contrast CT (NCCT)-Alberta Stroke Program Early CT Score (ASPECTS), diffusion-weighted imaging (DWI)-ASPECTS, and NCCT-ASPECTS combined with CTP (CT perfusion). However, there is no clear consensus on the optimal imaging modality for endovascular thrombectomy (EVT) trials of large core infarcts. The variety and complexity of imaging modalities make it difficult to apply them in clinical practice.

However, several disadvantages continue to be associated with this type of treatment, including a high local failure rate (reaching ~50% within 3 years) and a median overall survival (OS) time of 16.9 months.

Because of these advantages, neoadjuvant therapy is recommended for numerous types of tumor, such as breast, lung and rectal cancer. To determine the role of neoadjuvant therapy on overall survival and adverse for patients with resectable esophageal carcinoma.

Methods: Incidence and mortality rate data of CC in China were described using GBD 2019 data. The Joinpoint regression analysis and age-period-cohort model were implemented to describe temporal trends of CC in China over the past 30 years.
Water contamination caused by organic dyes has become a significant concern, and catalytic degradation of dye pollutants is an effective solution. However, developing an affordable, easy-to-prepare, high-catalytic-activity, and renewable catalyst has proved challenging. The current study addresses this issue by introducing an efficient heterogeneous Fenton catalyst, known as multivalent iron-based magnetic porous biochar (mFe-MPB).

Objective: To explore the underlying mechanism of acupuncture on nerve repair by investigating its effect on the differentiation of glial cells and the repair of glial scars.
Methods: Sprague-Dawley rats were randomly allocated to three groups: normal group, model group, and acupuncture group. Acupuncture was applied at Renzhong (GV26), Baihui (GV20), Fengfu (GV16), Yamen (GV15) and Hegu (LI4) within 12 h after TBI modeling with a frequency of one session per day for 4 weeks.
Background: Traumatic brain injury (TBI) is a common brain injury with a high morbidity and mortality. The complex injury cascade triggered by TBI can result in permanent neurological dysfunction such as cognitive impairment. In order to provide new insights for elucidating the underlying molecular mechanisms of TBI, this study systematically analyzed the transcriptome data of the rat hippocampus in the subacute phase of TBI.
View Article and Find Full Text PDFAims: Recent investigations have already proved the neuroprotective efficacy of acupuncture in clinical practice in the treatment of neurological diseases, such as traumatic brain injury (TBI). Since growing evidence has suggested that neuronal autophagy was involved in multiple stages of TBI, this study aims to clarify the autophagy mediating mechanism underlying the neuroprotective effect of acupuncture in TBI rats.
Methods: Three experiments were carried out to detect changes in neuronal autophagy and identify the potential molecular mechanism underlying the neuroprotective effect of acupuncture for TBI treatment.
Objective: Neuroinflammation caused by traumatic brain injury (TBI) can lead to neurological deficits. Acupuncture can inhibit neuroinflammation and promote nerve repair; however, the specific mechanism is still unclear. The purpose of this study was to explore whether acupuncture could modulate the M1 and M2 phenotypic polarization of microglia in a rat model of TBI via the toll-like receptor 4 (TLR4)/intracellular toll-interleukin-1 receptor (TIR) domain-containing adaptor inducing interferon-β (TRIF)/myeloid differentiation factor 88 (MyD88) pathway.

Acupuncture may be an effective therapy for UC. Here we focused on manual acupuncture and electroacupuncture (MA/EA), two widely used and studied acupuncture interventions, to probe the effects of acupuncture parameters on clinical efficacy in patients with UC and the use of MA/EA alone or with other drugs to support their wider adoption in clinical practice.

Neurogenic bladder and bowel are two critical autonomic complications following traumatic spinal cord injury (TSCI). Chronic lower urinary tract and bowel dysfunctions can lead to secondary complications, drastically affect the quality of life and significantly increase the risk of hospital readmission and mortality. Other than symptomatic treatments, a few effective therapies are available.

We systematically searched for phase 3 randomized controlled trials (RCTs) that compared semaglutide with placebo or other anti-diabetic drugs in T2D patients. The primary outcome was the change from baseline in glycated hemoglobin (HbA) levels.
