Article Synopsis
  • Silicon quantum dots are being explored for spin qubit applications because of their strong intrinsic spin-orbit coupling, which influences hole-spin dynamics.
  • The study demonstrates a singlet-triplet qubit using hole states in a metal-oxide-semiconductor double quantum dot, achieving rapid control with oscillations up to 400 MHz and a maximum coherence time of 1.3 μs.
  • This research identifies ways to enhance qubit performance and lays the groundwork for scaling up to larger arrays of qubits in two-dimensional configurations.

Introduction: The evolution of treatment for diabetic nephropathy illustrates how basic biochemistry and physiology have led to new agents such as SGLT2 inhibitors and mineralocorticoid blockers. Conversely, clinical studies performed with these agents have suggested new concepts for investigational drug development. We reviewed currently available treatments for diabetic nephropathy and then analyzed early clinical trials of new agents to assess the potential for future treatment modalities.

Holes in silicon quantum dots are receiving attention due to their potential as fast, tunable, and scalable qubits in semiconductor quantum circuits. Despite this, challenges remain in this material system including difficulties using charge sensing to determine the number of holes in a quantum dot, and in controlling the coupling between adjacent quantum dots. We address these problems by fabricating an ambipolar complementary metal-oxide-semiconductor (CMOS) device using multilayer palladium gates.

Introduction: In the last several decades, fueled by gene knockout and knockdown techniques, there has been substantial progress in detailing the pathways of gluconeogenesis. A host of molecules have been identified as potential targets for therapeutic intervention. A number of hormones, enzymes and transcription factors participate in gluconeogenesis.

Article Synopsis
  • The COVID-19 pandemic has multiple phases, with current treatment strategies largely focusing on late-stage disease in hospitals, while the viral phase in outpatients remains a key issue.* -
  • A review of 111 publications identified only 21 focusing on outpatient care, highlighting an imbalance in research and available treatments for patients not requiring hospitalization.* -
  • The authors advocate for public health authorities to approve low-risk treatments for outpatients alongside vaccination efforts, especially in light of emerging SARS-CoV-2 variants and limited monoclonal antibody supply.*

Pharmacotherapeutic options for prediabetes.

Expert Opin Pharmacother

January 2021

Introduction: 'Prediabetes' is a condition of elevated glucose not attaining the established criteria for a diagnosis of diabetes. The United States Diabetes Prevention Program (DPP) began in 1996 and was the iconic study of prediabetes. In that study, after 3 years, the risk of reaching the numerical criteria of diabetes was reduced by 58% by intensive emphasis on diet and exercise whereas treatment with metformin achieved a lesser reduction of 31%.

Familial atypical multiple mole melanoma (FAMMM) syndrome is a hereditary cancer syndrome that results from mutations in several genes, including the gene. In addition to melanoma, certain other malignancies such as pancreatic cancer are known to occur more frequently in family members who carry the mutation. However, as these families have been followed over time, additional cancers have been observed in both carriers and noncarriers.

Article Synopsis
  • Gene knockout technology allows scientists to study the role of specific genes, with Lexicon being a leader in developing high-throughput methods and agents to inhibit gene products.
  • Two of their key products, telotristat and sotagliflozin, are in late-stage development; telotristat inhibits serotonin production to treat carcinoid syndrome, while sotagliflozin targets glucose regulation in type 1 and type 2 diabetes.
  • Sotagliflozin aims to enhance glucose control by affecting both renal and intestinal glucose handling, but raises concerns due to a higher incidence of diabetic ketoacidosis (DKA) in type 1 diabetes trials compared to placebo.

Although premixed fixed ratio NPH insulin products are commonly used in type 2 diabetes patients, the advent of Glargine insulin which cannot be formulated together with a rapid-acting insulin (basal-bolus) has largely eliminated premixed insulin from use in type 1 diabetes. Degludec insulin can be formulated together with Aspart insulin in a 70/30 fixed ratio product. We review the potential use of Degludec-Aspart in type 1 diabetes.

Article Synopsis
  • * Initial studies focused on type 1 diabetes, showing that sotagliflozin reduces HbA1c levels and glucose variability, but it also has a higher risk of diabetic ketoacidosis (DKA) compared to placebo.
  • * The drug is now being tested for type 2 diabetes, with future studies needed to weigh its benefits and risks as an alternative to existing SGLT2 inhibitors.

Albiglutide is a long acting GLP-1 receptor agonist (GLP-1 RA) administered by weekly injection and approved for use in type 2 diabetes. It has less gastrointestinal side effects than other GLP-1 RAs in current use but does not improve HbA1c or promote weight loss to the same extent as some competitor agents. Area covered: The current use of albiglutide is discussed.

Background: Point-of-care (POC) testing of HbA1c is used as a time-efficient tool to improve treatment and management planning for diabetes in the clinic setting. HbA1c values are the basis for monitoring ongoing response to treatment and to make adjustments to diabetes therapy. Yet, there is ongoing controversy as to the accuracy of POC assays.
