3D bioprinting has become a leading contender among additive manufacturing techniques in biomedicine, offering the potential to create functional tissues and organs that could eliminate the need for transplants. However, for complex tissues like muscle, neural, bone, and heart, bioinks need significant improvements in properties like printability, mechanical strength, and functionalities crucial for mimicking natural tissues. Nanomaterial-based bioinks offer exciting possibilities.

This delay is attributed to the increased levels of reactive oxygen species (ROS) in these populations due to the accumulation of senescent cells. Tissue-engineered scaffolds are emerging as an alternative method to treat bone defects.

In this case, shape deformations occur due to the non-uniform distribution of internal stresses, asymmetrical swelling, and shrinking of different parts of the same hydrogel. Herein, we discuss the four-dimensional (4D) fabrication techniques (extrusion-based printing, dynamic light processing, and solvent casting) employed to prepare shape-shifting hydrogels.

The evolution of antiviral therapy for HCV has rapidly progressed from interferon (IFN)-based therapies to IFN-free combinations of direct-acting antivirals (DAAs).
Aims: This study aims to assess the response of DAAs in chronic hepatitis C (CHC) patients and to study the various factors affecting the response of DAAs in CHC.
Fibrosis has been characterized as a global health problem and ranks as one of the primary causes of organ dysfunction. Currently, there is no cure for pulmonary fibrosis, and limited therapeutic options are available due to an inadequate understanding of the disease pathogenesis. The absence of advanced models replicating dynamic temporal changes observed in the tissue with the progression of the disease is a significant impediment in the development of novel antifibrotic treatments, which has motivated research on tissue-mimetic three-dimensional (3D) models.

The emergence of digital ways of working, expedited by the COVID-19 pandemic, means that pharmaceutical-healthcare relationships are evolving to operate in an increasingly virtual world. The value of the pharmaceutical medical affairs function is dependent on understanding customers' needs and providing the right knowledge at the right time to physicians.

We are reporting a patient who presented with an erythematous plaque over the nose, which was proved to be due to leprosy. We think that this type of clinical feature is not a common presentation for leprosy.

In dermatology, specialized techniques like plasmapheresis and extracorporeal photochemotherapy have provided a good treatment option in immune-mediated disorders like bullous dermatoses, collagen vascular diseases and cutaneous lymphomas. Other anecdotal and less substantiated reports point to its use in chronic disorders like atopic dermatitis and psoriasis.
