AIM: Lignolytic (Lignin degrading) enzyme, from oil palm pathogen Ganoderma boninense Pat. (Syn G. orbiforme (Ryvarden), is involved in the detoxification and the degradation of lignin in the oil palm and is the rate-limiting step in the infection process of this fungus. Active inhibition of lignin degrading enzymes secreted by G. boninense by various naturally occurring phenolic compounds and estimation of efficiency on pathogen suppression was aimed at. METHODS AND RESULTS: In our work, ten naturally occurring phenolic compounds were evaluated for their inhibitory potential towards the lignolytic enzymes of G...

Rice bodies are very unusual lesions, generally encountered in chronic synovitis due to rheumatoid diseases or tuberculosis. A 31-year-old right-handed man presented with a 15-year history of progressively growing "sausage-like" swelling of the 4th finger and palm of his right hand. There was an immovable, painless mass with restriction of the finger's ROM without local or general associated signs. Imaging showed a large non-aggressive mass within the tendon sheath. Complete excision of the mass was performed...

Acid-sensing ion channels (ASICs) are trimeric proton-gated cation permeable ion channels expressed primarily in neurons. Here we employed site-directed mutagenesis and electrophysiology to investigate the mechanism of inhibition of ASIC1a by diminazene. This compound inhibits mouse ASIC1a with a half-maximal inhibitory concentration (IC50) of 2.4 μM. At first, we examined whether neutralizing mutations of Glu79 and Glu416 alter diminazene block. These residues form a hexagonal array in the lower palm domain that was previously shown to contribute to pore opening in response to extracellular acidification...

Dear Editor, Tuberous sclerosis (TS) is an autosomal dominant multisystem disease, which occurs due to genetically determined hyperplasia of ectodermal and mesodermal cells. Clinical manifestations present on the skin and in the nervous system, kidneys, heart, and other organs. Recent studies estimate the incidence of TS at 1/6000 to 1/10,000 live births, and a prevalence in the general population of approximately 1 in 20,000 (1). There are two different genetic loci responsible for TS: 9q34 (TSC1-hamartin) and 16p13...

Dear Editor, Gestational pemphigoid (GP) is a rare autoimmune bullous dermatosis in pregnancy. GP usually occurs during the second or third month of pregnancy. It clinically manifests as the development of either early-onset urticarial lesions or late-onset subepidermal blisters that may linger for weeks or even months. Herein we report the case of a 45-year-old woman with the distinctive clinical onset of GP. A forty-five-year-old woman, gravida I, para 0, at 27 weeks gestation, was referred for evaluation to our Department with an extensive pruritic eruption that had developed over the previous 7 days...

Optically detected magnetic resonance (ODMR) of triplet states populated by photoexcitation in the Water-Soluble Chlorophyll Protein (WSCP) from Lepidium virginicum has been performed, using both absorption and fluorescence detection. Well resolved Triplet minus Singlet (T-S) spectra have been obtained, which have been interpreted in terms of electronic interactions among the four chlorophylls (Chls) forming two dimers in WSCP tetramer. Localization of the triplet state on a single Chl leads to a redistribution of the oscillator strenght in the remaining three Chls of the complex...

BACKGROUND AND PURPOSE: Agonists for the liver X receptor (LXR) are considered promising therapeutic moieties in cholesterol-driven diseases by promoting cellular cholesterol efflux pathways. However, current clinical application of these agents is hampered by the concomitant LXR-induced activation of a lipogenic transcriptional network, leading to hepatic steatosis. Recent studies have suggested that protein arginine methyltransferase 3 (PRMT3) may act as a selective co-activator of LXR activity...

The mammalian secretoglobin (SCGB) superfamily contains functionally diverse members, among which the major cat allergen Fel d 1 and mouse salivary androgen-binding protein (ABP) display similar subunits. We searched for molecular similarities between Fel d 1 and ABP to examine the possibility that they play similar roles. We aimed to i) cluster the evolutionary relationships of the SCGB superfamily; ii) identify divergence patterns, structural overlap, and protein-protein docking between Fel d 1 and ABP dimers; and iii) explore the residual interaction between ABP dimers and steroid binding in chemical communication using computational approaches...

Keratoacanthoma (KA) is a squamous neoplasm exhibiting a triphasic growth pattern involving rapid growth, stabilization, and eventual spontaneous resolution. Historically, keratoacanthomas were thought to originate on hair-bearing skin or sun-exposed surfaces. However, recent reports demonstrate that they can occur on the mucous membranes, subungual regions, and palms and soles. We report a 74-year-old man who developed a KA on the left palmar surface after minor trauma, for which he underwent Mohs' micrographic surgery...

In current practice, oil palm frond leaflets and stems are re-used for soil nutrient recycling, while the petioles are typically burned. Frond petioles have high commercialization value, attributed to high lignocellulose fiber content and abundant of juice containing free reducing sugars. Pressed petiole fiber is the subject of interest in this study for the production of lignocellulolytic enzyme. The initial characterization showed the combination of 0.125 mm frond particle size and 60% moisture content provided a surface area of 42...
