Natural Cartilage-Derived Scaffolds for 3D Mesenchymal Stem Cell Culture: Promoting Chondrogenesis and Modulating Secretome Composition

Abstract: Introduction: The regenerative potential of stem cells lies in their secretome, a collection of signaling molecules whose composition is shaped by the cellular microenvironment and external stimuli. To enhance cartilage regeneration, a 3D culture system using a natural cartilage scaffold has been developed to create a more chondrogenic secretome. This study investigates the chondrogenic differentiation of mesenchymal stem cells (MSCs) cultured in a decellularized bovine cartilage scaffold and analyzes the resulting secretome's composition. Methods: This study employed a randomized time series design to examine MSCs chondrogenic differentiation. A control group was cultured in standard 2D conditions, while two experimental groups were cultured in either 2D medium supplemented with chondrocyte differentiation medium (positive control) or a 3D decellularized bovine cartilage scaffold.

Ethyl Acetate Extract of Fungus Comb from Malayan Termite (Macrotermes Gilvus Hagen) Mound Modulates Splenic Inflammatory Responses in Mice

ABSTRACT Background: The fungus comb is a unique structure inside termites’ nests that facilitates the growth of Termitomyces sp. as a nutrient source for the termites. It is known to possess immunomodulatory properties that boost the immune system. Aim: The objective of this study was to assess the impact of ethyl acetate extract of fungus comb (EAEFC) on the inflammatory reaction in the spleen of mice induced by intraperitoneal injection of lipopolysaccharide (LPS). Methods: An experimental study was conducted using a post-test-only control group design with male BALB/C mice (n = 24). The mice were divided randomly into four groups, each comprising six mice, and administered substances via gavage. Groups I and III were administered a solution of 5% dimethyl sulfoxide (DMSO) in distilled water, while Groups II and IV were given 500 mg/kg BW EAEFC dissolved in 5% DMSO.

Selectively mixed matrix hemodialysis membrane for adequate clearance of p-cresol by the incorporation of imprinted zeolite

Abstract The adequacy in uremic toxin removal upon hemodialysis treatment is essential in patients with kidney failure diseases as poor removal leads to heart failure, hypertension, and stroke. The combination of adsorption and diffusion processes has become very advantageous for hemodialysis membranes. By this mechanism, water-soluble uremic toxins (WSUTs) and protein-bounded uremic toxins (PBUTs) could be removed at one time. Therefore, this study aimed to develop a novel imprinted zeolite by p-cresol (IZC) and then incorporated it into polyethersulfone (PES) and poly(vinyl pyrrolidone) (PVP) to produce hollow fiber mixed matrix membrane (HF-MMM). The IZC proved to be sensitive in attracting the adsorbate, classifying it as having a strong adsorption behavior.

Brown Tumour in Chronic Kidney Disease: Revisiting an Old Disease with a New Perspective

Simple Summary OFC (Osteitis Fibrosa Cystica) and Brown Tumours, skeletal lesions commonly found in chronic kidney disease (CKD) patients, are influenced by various risk factors, such as age, sex, medications affecting calcium metabolism, and vitamin D deficiency. The primary cause is secondary hyperparathyroidism, leading to imbalances in calcium and phosphorus levels and osteoclast activation. Other factors, like RAAS hyperactivity and chronic inflammation, may also contribute to their development. The recently described involvement of KRAS mutations turned Brown Tumours from reactive lesions to potentially neoplastic lesions. To manage these conditions, pharmacologic treatments like bisphosphonates, calcimimetics, vitamin D supplementation, and denosumab can help by reducing hyperparathyroidism, restoring calcium levels, and preventing OFC occurrence.

Hematological Profile of Mice After Ethyl Acetate Extract of Fungus Comb of Indo-Malayan Termite (Macrotermes gilvus Hagen) Mound Supplementation in Regulating Lipopolysaccharide-induced Inflammatory Response

ABSTRACT Introduction: Termitomyces sp. is an edible fungal species commonly found in tropical forests in Africa and Southeast Asia. It is consumed as an immunomodulatory agent to enhance the immune system. This study explored the hematological profile of ethyl acetate extract of fungus comb(EAEFC) on mice’s inflammatory response induced by intraperitoneally-injected lipopolysaccharide. Methods: An experimental study with a post-test-only control group design using BALB/C mice(n = 24, bodyweight/BW:25-30 grams) was conducted. The animals were randomly allocated into 4 groups, each consisting of 6 mice, and received substance(s) via gavage. Groups I and III received 5% Dimethyl Sulfoxide(DMSO) in water, groups II and IV received 500mg/kg BW EAEFC in 5% DMSO. On day 15, Group I and II were injected intraperitoneally with 5 ml/kg BW saline, whereas Group III and IV with 10 mg/kg BW lipopolysaccharide(LPS) in 5 ml/kg BW saline. After three hours, the mice were sacrificed; their blood was collected, and a hematological profile was observed. The results were displayed as mean ± standard deviation (SD), and the differences between groups were statistically analyzed using one-way ANOVA.
