Background: The purpose of this article is to describe a technique which helps in fabrication of glove-type hollow thumb prosthesis using three-part mould technique.
Case Description And Methods: Patient reported to the Department of Private dental clinic, Delhi, India with a chief complaint of missing partial left thumb and wanted to get it replaced. A complete clinical hand examination was carried out, which revealed a residual stump of 1 cm length. After ensuring the medical conditions to be normal, fabrication of hollow thumb prosthesis was planned using three-part mould technique.
Findings And Outcomes: The prosthesis delivered to the patient was highly retentive because of its glove-type retention and lighter weight; feedback from the patient regarding retention was excellent. The prosthesis was aesthetically pleasing because of its excellent colour matching with the skin, and each and every part of the prosthesis could be colour customized because of easy retrieval of the third part of the mould, as well.
Conclusion: A technique of hollow thumb prosthesis has been described in this article which helps in reduction in weight, easy packing of silicone material into the mould and easy colour customization at the knuckles area of the dorsal and ventral aspect of the prosthesis.
Clinical Relevance: This three-part mould technique helps to fabricate hollow prosthesis which increases retainability and at the same time allows easy packing of silicone material and easy colour customization at the knuckles area of the prosthesis.

The food industry holds immense promise for 3D printing technology. Current research focuses mainly on optimizing food material composition, molding characteristics, and printing parameters. However, there is a notable lack of comprehensive studies on the shape changes of food products, especially in modeling and simulating deformations.

Context: The phenomena of olfactory and gustatory dysfunction disorders (OGD) are hardly unique to COVID-19. However, the widespread incidence of OGD as sequelae of COVID-19 has provoked rejuvenated interest in these long existing, but poorly studied maladies.
Objective: This second of a three-part review discusses past and current approaches for treatment of OGD, not restricted to those that COVID-19 has caused, with the intention to lay a foundation for consideration of new paradigms for evaluation and management of OGD.
Context: Amelioration of olfactory and gustatory dysfunction (OGD) disorders has become a common requirement due to COVID-19. Although it's hardly exclusive to COVID-19, OGD's prevalence requires exploration of therapeutic and restorative modalities, on the broadest scale possible. No specific medication or treatment of any noteworthy efficacy exists for OGD.

The unfortunate loss of all or part of a finger caused by traumatic amputation has a negative impact on physical and psychological well-being of a person. Thus an aesthetic prosthesis can offer psychological, functional and rehabilitative advantages. One of the major problems with the prosthetic replacement of a partially amputated finger is inadequate retention of the prosthesis and there are numerous means to enhance the retention.

Expression of secreted recombinant proteins burdens the protein secretion machinery, limiting production. Here, we describe an approach to improving protein production by the non-conventional yeast Komagataella phaffii comprised of genome-wide screening for effective gene disruptions, combining them in a single strain, and recovering growth reduction by adaptive evolution. For the screen, we designed a multiwell-formatted, streamlined workflow to high-throughput assay of secretion of a single-chain small antibody, which is cumbersome to detect but serves as a good model of proteins that are difficult to secrete.
