Exploring the seas for cancer cures: the promise of marine-derived bioactive peptide.

Marine environments harbor a wealth of bioactive peptides with potential anticancer properties, sourced from diverse organisms like tunicates, sea sponges, and mollusks. Through isolation, identification, and modification, peptides such as Stylisin and Papuamides have shown enhanced activity and progressed to clinical trials, underscoring their therapeutic promise. Enzymatic hydrolysis emerges as a favored method for peptide extraction from marine proteins, with sponges identified as particularly rich sources.

Density functional theory and molecular dynamics simulation of water molecules confined between two-dimensional graphene oxide surfaces.

In this work, the interaction potentials of water molecule with the two-dimensional graphene oxide (GO) surfaces containing epoxy groups have been determined using the M06-2X/6-31g (d,p) level of theory at different orientations and separations and fitted to the Born-Huggins-Meyer (BHM) potential. Good agreements were found between the computed and the well-known OPLS-AA and Dreiding potentials. We have also used some calculated potentials and the well-known models in the molecular dynamics (MD) simulations.

Poly (I:C) increases the expression of and genes in exosomes isolated from human Wharton's jelly mesenchymal stem cells.

Background: Mesenchymal stem cells (MSCs) are commonly employed as a powerful tool for the treatment of immune-mediated problems owing to their capacity to regulate the immune system and differentiate into different tissues. Researchers use mesenchymal stem cell products given the limitations associated with the application of MSCs. Exosomes are nanometer vesicles derived from MSCs that are used in cell-free therapy.

Preparation and Evaluation of Berberine-Excipient Complexes in Enhancing the Dissolution Rate of Berberine Incorporated into Pellet Formulations.

Berberine is used in the treatment of metabolic syndrome and its low solubility and very poor oral bioavailability of berberine was one of the primary hurdles for its market approval. This study aimed to improve the solubility and bioavailability of berberine by preparing pellet formulations containing drug-excipient complex (obtained by solid dispersion). Berberine-excipient solid dispersion complexes were obtained with different ratios by the solvent evaporation method.

The Advantages of 4-rod Construct over the 2-rod Techniques in Adult Spinal Deformity Patients who Underwent Pedicle Subtraction Osteotomy: A Multicenter Retrospective Comparative Study.

Objective: In this retrospective study we compared clinicoradiologic outcomes and complication profiles of the traditional 2-rod construct versus the 4-rod construct in patients with adult spinal deformity (ASD) who underwent pedicle subtraction osteotomy (PSO).

Methods: We performed a retrospective review of 208 ASD patients at 2 referral centers who underwent lumbar PSO and long fusion from thoracic to the pelvis. Two different techniques, including the 4-rod construct and the traditional 2-rod technique, were used at the PSO level.

Evaluation of silver sulfadiazine 1%-cerium nitrate 2.2% cream efficacy and safety in moderate to severe burn patients: a single-blind randomized clinical trial.

Background: Burn injury is a major global health crisis. Topical antimicrobials such as silver sulfadiazine (SSD) are commonly used for superficial burn wounds. SSD has a broad-spectrum antimicrobial activity and also anti-inflammatory property, but also suffers from some limitations.

Phylogenetic comparative analysis of the cerebello-cerebral system in 34 species highlights primate-general expansion of cerebellar crura I-II.

The reciprocal connections between the cerebellum and the cerebrum have been suggested to simultaneously play a role in brain size increase and to support a broad array of brain functions in primates. The cerebello-cerebral system has undergone marked functionally relevant reorganization. In particular, the lateral cerebellar lobules crura I-II (the ansiform) have been suggested to be expanded in hominoids.

The effects of propolis supplementation on high-sensitivity C-reactive protein, testosterone hormone, and metabolic profile in women with polycystic ovary syndrome: A randomized, triple-blinded, placebo-controlled clinical trial.

One of the most prevalent ovulation disorders is polycystic ovarian syndrome (PCOS). According to the anti-inflammatory and beneficial effects of propolis, this triple-blind controlled trial was designed to evaluate the effect of propolis on metabolic factors, high-sensitivity C-reactive protein, and testosterone in women with PCOS. Recruited patients from the gynecologist clinic were randomized based on a stratified permuted four-block randomization procedure to supplement with propolis tablets, two tablets/day (500 mg propolis/day) (n = 30) or identical placebo tablets (n = 30) for 12 weeks in 2021 until 2022.

Investigation of small inhibitor effects on methane hydrate formation in a carbon nanotube using molecular dynamics simulation.

In this work, we simulated water molecules in fixed and rigid (15,0) CNTs and the confined water molecules formed a hexagonal ice nanotube in the CNT. After the addition of methane molecules in the nanotube, the hexagonal structure of confined water molecules disappeared and were replaced by almost all the guest methane molecules. The replaced molecules formed a row of water molecules in the middle of the hollow space of the CNT.

A review on curcumin colon-targeted oral drug delivery systems for the treatment of inflammatory bowel disease.

Synthetic drugs and monoclonal antibodies are the typical treatments to combat inflammatory bowel disease (IBD). However, side effects are present when these treatments are used, and their continued application could be restricted by the high relapse rate of the disease. One potential alternative to these treatments is the use of plant-derived products.
