AI Article Synopsis

  • Plant lesion mutation is when green plant tissues undergo cell death before dying naturally, which is linked to better resistance against diseases.
  • In rice, this phenomenon is influenced by gene mutations, buildup of reactive oxygen species, uncontrolled cell death processes, and environmental stress.
  • The study reviews how these lesion mimic mutants occur in rice and investigates the functions of specific genes involved to understand how they help the plant resist diseases.

Article Abstract

Plant lesion mutation usually refers to the phenomenon of cell death in green tissues before senescence in the absence of external stress, and such mutants also show enhanced resistance to some plant pathogens. The occurrence of lesion mimic mutants in rice is affected by gene mutation, reactive oxygen species accumulation, an uncontrolled programmed cell death system, and abiotic stress. At present, many lesion mimic mutants have been identified in rice, and some genes have been functionally analyzed. This study reviews the occurrence mechanism of lesion mimic mutants in rice. It analyzes the function of rice lesion mimic mutant genes to elucidate the molecular regulation pathways of rice lesion mimic mutants in regulating plant disease resistance.

Inflammatory Signatures in VEXAS Syndrome, Myelodysplasia Cutis, and Sweet Syndrome.

JAMA Dermatol

March 2025

Service de Dermatologie et Allergologie, Faculté de Médecine, Sorbonne Université, Hôpital Tenon, Assistance Publique-Hôpitaux de Paris, Paris, France.

Importance: VEXAS syndrome (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) is a monogenic disease caused by UBA1 somatic variants in hematopoietic progenitor cells, mostly involving adult men. It is associated with inflammatory-related symptoms, frequently involving the skin and hematological disorders. Recently described myelodysplasia cutis (MDS-cutis) is a cutaneous manifestation of myelodysplasia in which clonal myelodysplastic cells infiltrate the skin.

Multimodal integration of liquid biopsy and radiology for the noninvasive diagnosis of gallbladder cancer and benign disorders.

Electronic address:

Gallbladder cancer (GBC) frequently mimics gallbladder benign lesions (GBBLs) in radiological images, leading to preoperative misdiagnoses. To address this challenge, we initiated a prospective, multicenter clinical trial (ChicCTR2100049249) and proposed a multimodal, non-invasive diagnostic model to distinguish GBC from GBBLs. A total of 301 patients diagnosed with gallbladder-occupying lesions (GBOLs) from 11 medical centers across 7 provinces in China were enrolled and divided into a discovery cohort and an independent external validation cohort.

Central Pathologies Imitating Peripheral Causes of Vertigo.

Indian J Otolaryngol Head Neck Surg

February 2025

Department of ENT & HNS, Command Hospital (EC), Kolkata, India.

To differentiate central vertigo mimicking peripheral vestibular diseases with proper history taking, examination and imaging to enable early diagnosis and management. This was an Observational Study carried out over two years and targeted patients across all age groups presenting with complaints of vertigo in ENT OPD of hospitals of the Armed Forces. All patients in all age groups for both genders were included, even those who had presented with recurring symptoms having been managed conservatively elsewhere.

Purpose: Multinodular and vacuolating neuronal tumor (MVNT) is a rarely diagnosed neoplastic lesion often associated with adult-onset focal seizures. In some situations, atypical MRI features of MVNT may mimic other long-term epilepsy associated tumors (LEATs) or diffuse low-grade gliomas. In such a context, the identification of distinct clinical markers is recommended.

Background And Purpose: The Artery of Percheron (AoP) supplying bilateral paramedian thalami and rostral midbrain is a rare anatomical variant. In the event of occlusion of AoP, a characteristic pattern of ischaemia is seen, presenting as bithalamic signal abnormality on magnetic resonance imaging (MRI). However, this particular imaging finding has significant radiological and clinical overlap with other conditions, necessitating a comprehensive understanding of the imaging characteristics and potential differential diagnosis.
