Article Synopsis
  • In this study, researchers investigated how a conductive hydrogel combined with electrical stimulation can improve skin healing for complex injuries.
  • They developed hydrogels using polypyrrole with gelatin and silk fibroin, achieving high electrical conductivity while ensuring the gels are stable and compatible with living cells.
  • The results showed that electrical stimulation significantly boosted specific protein and gene expressions related to skin regeneration, suggesting that this method could speed up healing processes.

The present study reports the synthesis of micellar conjugates, wherein curcumin (Cur), a bioactive compound with poor bioavailability, was covalently bonded to a bacterial exopolysaccharide (EPS). These conjugates were synthesized by utilizing succinic acid that linked Cur to the pyranosyl moiety of the EPS. The Cur-EPS conjugates appeared as spherical micelles in aqueous solution and were found to have an average hydrodynamic diameter of 254 ± 2.

Stainless steel (316L SS) has been widely used in orthopedic, cardiovascular stents, and other biomedical implant applications due to its strength, corrosion resistance, and biocompatibility. To address the weak interaction between steel implants and tissues, it is a widely adopted strategy to enhance implant performance through the application of bioactive coatings. In this study, Cu-doped brushite coatings were deposited successfully through pulse electrodeposition on steel substrates facilitated with a biosurfactant (BS) (i.

The quest for an ideal wound dressing material has been a strong motivation for researchers to explore novel biomaterials for this purpose. Such explorations have led to the extensive use of silk fibroin (SF) as a suitable polymer for several applications over the years. Unfortunately, another major silk protein-sericin has not received its due attention yet in spite of having favorable biological properties.

Wound healing (WH) is a complex and dynamic process that comprises of a series of molecular and cellular events that occur after tissue injury. The injuries of the maxillofacial and oral region caused by trauma or surgery result in undesirable WH such as delayed wound closure and formation of scar tissue. Skin tissue engineering (TE)/regeneration is an emerging approach toward faster, superior, and more effective resolution of clinically significant wounds effectively.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), is a highly transmissible virus causing the ongoing global pandemic, COVID-19. Evidence suggests that viral and host microRNAs play pivotal roles in progression of such infections. The decisive impact of viral miRNAs and their putative targets in modulating the transcriptomic profile of its host, however remains unexplored.

Hemoglobin E (HbE)/β-thalassemia is a form of β-hemoglobinopathy that is well-known for its clinical heterogeneity. Individuals suffering from this condition are often found to exhibit increased fetal hemoglobin (HbF) levels - a factor that may contribute to their reduced blood transfusion requirements. This study hypothesized that the high HbF levels in HbE/β-thalassemia individuals may be guided by microRNAs and explored their involvement in the disease pathophysiology.

Hydrophobic drug molecules pose a significant challenge in immobilization on super-hydrophobic metallic surfaces like conventional titanium implants. Pre-coating surface modifications may yield a better platform with improved wettability for such purposes. Such modifications, as depicted in this study, were hypothesized to provide the requisite roughness to assist deposition of polymers like silk fibroin (SF) as a drug-binding matrix in addition to significant improvement in early protein adsorption, which facilitates faster cellular adhesion and proliferation.

Combination of naturally occurring materials instead of chemically synthesized products has always been an attractive proposition in the field of tissue engineering. In this study, silk fibroin (SF) and xanthan gum(XG) were physically crosslinked to form biocompatible hydrogels. SF/XG hydrogels were prepared using ultrasonication, which induces β-sheets from random coils in SF solution and allows entrapment of heated XG chains homogeneously in the SF network.

Gelatin based hydrogel (Gel) possess remarkable cytocompatibility profile rendering it appropriate for tissue engineering applications. Herein, the questionable mechanical property of Gel was tuned by tailoring with different loading concentrations of silk fibroin (SF). The as tailored matrix was reconnoitred for its physico-mechanical, chemical and biological properties in order to investigate the effect of SF loading.

The baculovirus expression vector system (BEVS) is an emerging tool for the production of recombinant proteins, vaccines and bio-pesticides. However, a system-level understanding of the complex infection process is important in realizing large-scale production at a lower cost. The entire baculovirus infection process is summarized as a combination of various modules and the existing mathematical models are discussed in light of these modules.
