Orbital Tumours in Northern Malaysia: A Five-Year Review.

Background: This study was conducted with the objective to examine demographic statistics and histopathological diagnoses of orbital biopsies from cases referred to the Oculoplastic subspecialty of the Ophthalmology department in Hospital Sultanah Bahiyah, Kedah, from 2016 to 2020.

Method: This study is a case series of 28 patients who underwent orbital biopsy.

Result: A total of 34 orbital biopsies from 28 patients were recorded.

Eyelid Tumours in Northern Malaysia: A Five-Year Review.

Background The majority of eyelid tumours are benign in nature and constitute 82%-98% of all eyelid tumours. This study aimed to explore the prevalence and frequency of histopathological diagnoses of eyelid tumours encountered in Hospital Sultanah Bahiyah (HSB), Malaysia, from 2016 to 2020. Method This study is a case series of 136 patients with eyelid tumours who underwent eyelid biopsy.

The Dominant and Poorly Penetrant Phenotypes of Maize Are Caused by DNA Methylation Changes at a Linked Transposon.

The maize () mutant () has been implicated in the epigenetic modifications of (), which regulates the production of the flavonoid pigments phlobaphenes. Here, we show that the gene maps to a genetically recalcitrant region near the centromere of chromosome 10. Transcriptome analysis of mutant and wild-type plants identified a candidate gene in the mapping region using a comparative sequence-based approach.

A sorghum MYB transcription factor induces 3-deoxyanthocyanidins and enhances resistance against leaf blights in maize.

Sorghum responds to the ingress of the fungal pathogen Colletotrichum sublineolum through the biosynthesis of 3-deoxyanthocyanidin phytoalexins at the site of primary infection. Biosynthesis of 3-deoxyanthocyanidins in sorghum requires a MYB transcription factor encoded by yellow seed1 (y1), an orthologue of the maize gene pericarp color1 (p1). Maize lines with a functional p1 and flavonoid structural genes do not produce foliar 3-deoxyanthocyanidins in response to fungal ingress.
