Characterisation of High Alkaline-Tolerant Novel Ulvan Lyase from : Potential Applications of Enzyme Derived Oligo-Ulvan as Anti-Diabetic Agent.

Green algae, particularly species, are rich in complex polysaccharides, such as ulvan, which have significant potential for biotechnological applications. However, the biochemical properties of ulvan depolymerised products remain underexplored. The enzymatic depolymerisation of ulvan has garnered attention owing to its cost advantages over alternative methods.

Odd-Numbered Agaro-Oligosaccharides Produced by α-Neoagaro-Oligosaccharide Hydrolase Exert Antioxidant Activity in Human Dermal Fibroblasts.

Agarases produce agar oligosaccharides with various structures exhibiting diverse physiological activities. α-Neoagaro-oligosaccharide hydrolase (α-NAOSH) specifically cleaves even-numbered neoagaro-oligosaccharides, producing 3,6-anhydro-l-galactose (l-AHG) and odd-numbered agaro-oligosaccharides (OAOSs). In this study, α-NAOSH from the agar-degrading marine bacterium JEA5 (Gaa117) was purified and characterized using an expression system to produce OAOSs and determine their bioactivity.

Psoriasiform Lupus Vulgaris: A Diagnostic Challenge.

Cutaneous tuberculosis is a rare and often overlooked manifestation of tuberculosis, frequently leading to delays from onset to diagnosis. This case report describes the presentation of a 65-year-old male with an asymptomatic solitary plaque with silvery scales persisting for over five years, mimicking solitary plaque psoriasis. Despite intermittent treatment with a potent steroid and a combination of calcipotriol, the patient had only modest alleviation.

Nail Discoloration Following the Chronic Use of Skin-Depigmenting Creams.

Skin-depigmenting creams are on the rise, driven by societal pressures that equate fair skin with beauty, success, and happiness. This trend has led to many unregulated products being released on the market, causing various adverse effects on users. This case report examines five patients with nail hyperpigmentation following the use of skin-depigmenting creams containing hydroquinone (HQ).
