Simple Summary

Periodontitis is a common disease that affects the gums and the bone supporting the teeth, often leading to tooth loss. It results from a complex interaction between bacteria and the body’s immune response. Some people are more susceptible than others, and genetics may play a role. In this study, we focused on a genetic variation (called a polymorphism) in a gene known as TLR4, which helps the immune system recognize harmful bacteria. We examined over 1400 individuals from different populations and found that people carrying this specific variation, known as Asp299Gly, were less likely to develop severe periodontal …

Type I interferons are secreted in response to various stimuli and are used as a treatment for many diseases, including infections with the hepatitis B virus (HBV) and its satellite virus, hepatitis delta (HDV). HDV significantly aggravates HBV-mediated liver damage and is - in contrast to HBV - a strong inducer of interferon responses, including IFN-β. As the role of IFN- β in liver metabolism is so far ill explored, we studied its impact on hepatocyte metabolism in HDV-infected cultures. Transcriptome analysis, isotope tracing and functional tests on differentiated, HDV-infected hepatocytes showed reduction of mitochondrial TCA cycle and respiratory activity …

Ldt Fda Ruling: A Conundrum For Laboratories Across The Usa, Charma Henry

MSMLS Capstone Projects

Abstract

In the article “The Future of Laboratory Medicine Understanding the New Pressures," author Mauro Panteghini expresses that the clinical laboratory has always undergone significant changes due to technological advances and external economic pressures. “Laboratories are indeed an easy target for economic restrictions and limitations due to their technological characteristics.” (Panteghini, 2004, pg. 205) Though these words were written over 20 years ago, no more valid words have been spoken in light of the newest pressure all laboratories face with the new LDT regulation set by the FDA.

This regulation places drastic economic pressure on laboratories to pay the FDA …

Elimination Of Hiv Reservoirs Harboring Intact Proviruses, Min Li, Khanghy Truong, Suman Sharma, Baichao Sun, Min Chen, Jason T Kimata, Jin Wang

Faculty, Staff and Students Publications

Background: Human immunodeficiency virus (HIV) establishes persistent infection by integrating its proviral DNA into the host genome. While most integrated proviruses are defective, a small portion of proviruses are intact that represent a major obstacle to achieving an HIV cure. We have designed an approach for selective elimination of host cells harboring replication-competent HIV (SECH), through inhibition of autophagy and anti-apoptotic molecules during viral reactivation. However, the effects of SECH on the dynamics of intact and defective HIV provirus remain unclear.

Methods: We isolated DNA from HIV-infected samples after SECH treatments. We analyzed HIV-1 proviruses in these samples by intact …

Effect Of Vitamin  C As An Iron-Supporting Supplement In Adolescents With Suspected Iron Deficiency Anemia: Is It Effective For Increasing Hemoglobin Levels?, Ryan Pramana Putra, Nany Hairunisa, Refia Putri Restiana, Husnun Amalia, Emad Yousif

Iraqi National Journal of Medicine

Background: Anemia is a global health problem that affects adolescents, adults, and children in both developed and developing countries. Anemia in adolescent girls (10–19 years of age) is defined as a hemoglobin level in the blood of <12 g/dL. In Indonesia, the prevalence of iron deficiency anemia in adolescent girls reaches 48.9%. Iron supplementation can be enhanced with vitamin C as a companion supplement. Vitamin C increases iron absorption in the body by reducing Fe3+ to Fe2+, which requires an acidic environment for optimal dissolution and absorption. Aim: This study aims to assess the comparative effectiveness of iron supplementation with or without vitamin C in increasing hemoglobin levels. Methodology: An experimental design with consecutive sampling was conducted in September 2023 at Junior High School 1 Prambon, Nganjuk, East Java. The total sample consisted of 52 girls aged 12–13 years with anemia. The first group received iron and vitamin C, while the second group received iron only. Hemoglobin levels were  by the fingerstick method. Results: There were 32 samples (53.33%) aged 13 years. The average change in hemoglobin levels before and after intervention in group 1 was 2.238 g/dL with < 0.05, while in group 2 it was 0.661 g/dL with <0.05. The average difference in changes in hemoglobin levels between groups 1 and 2 after intervention was 1.303 g/dL with <0.05. Conclusion: Iron supplementation with vitamin C results in more significant increases in hemoglobin levels.

Cancer Vaccination And Immune-Based Approaches In Pancreatic Cancer, Matthew D. Bloom, Ali Raza Shaikh, Zhengyang Sun, Babar Bashir, Adam E. Snook

Department of Medical Oncology Faculty Papers

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy with high recurrence rates even after curative resection and adjuvant chemotherapy. Although immunotherapeutic approaches, such as immune checkpoint blockade (ICB), have revolutionized the treatment of some solid tumor malignancies, this has not been the case for PDAC. Several characteristics of PDAC, including its distinctive desmoplastic tumor microenvironment (TME), intratumor heterogeneity, and poor antigenicity and immune cell infiltration, contribute to its dismal immunotherapeutic landscape. Cancer vaccines offer one approach to overcoming these barriers, particularly in the resectable or borderline resectable settings, where tumor burden is low and immunosuppression is less pronounced. Various vaccination …
