Background: Hyperglycemia in diabetes mellitus (DM) can lead to dyslipidemia, which is a risk factor for macrovascular complications such as heart disease and stroke. Aside from administering antidiabetic medications, DM treatment can also be achieved through the use of natural components, such as , commonly known as the ant nest plant (ANP).

Aim: This study aimed to investigate the impact of administering the ANP on the lipid profile of Wistar rats.

Objective: Dementia is a common aging-related neurodegenerative disease in the elderly worldwide. Alterations in neurogenesis and angiogenesis factors have been linked to cognitive impairment in neurological disorders. However, synthetic drugs to improve memory disorders have uncomfortable side effects.

Background: Hyperglycemia conditions in diabetes mellitus (DM) can turn on pro-inflammatory cytokines like IL-6 and TNF-α. These cytokines play a role in insulin resistance and the development of DM complications. People in Indonesia have used to treat diabetes, but the leaf of this plant has not been studied to see if it can reduce inflammation.

Article Synopsis
  • This study investigates the factors influencing HBV DNA suppression in chronic hepatitis B patients receiving tenofovir disoproxil fumarate (TDF) over a 24-week period.
  • A case-control research was conducted involving 182 patients at two hospitals in Medan, Indonesia, where genetic and blood analyses were performed to evaluate various potential risk factors.
  • Findings revealed that specific CTLA-4 genetic polymorphisms, elevated CTLA-4 levels, high HBV DNA levels, and low ALT levels significantly increased the risk of not achieving HBV DNA suppression with TDF treatment, while no other demographic factors were found to impact the results.

Background: Tenofovir disoproxil fumarate (TDF) is a first-line nucleotide analog (NA) drug for hepatitis B therapy. Long-term NA therapy increases peripheral T cell levels to enhance antiviral response, while CTLA-4 inhibits the activation.

Objective: This study analyzed the interaction between TDF and CTLA-4 through molecular docking.

Article Synopsis
  • The study investigates how genetic factors, specifically polymorphisms in certain genes, affect hematological toxicity in breast cancer patients undergoing chemotherapy with anthracycline in Indonesia.
  • A total of 138 patients were analyzed through a retrospective cohort study, where their DNA was examined for specific polymorphisms and the impact on blood cell counts and anemia was measured.
  • Results showed a significant decrease in neutrophil count and an increase in anemia after chemotherapy cycles, but no significant relationship was found between the examined genetic polymorphisms (ABCB1 and GSTP1) and the occurrence of these hematological toxicities.

Introduction: Cervical spondylosis is the most common cause of myelopathy in the cervical due to chronic compression of the spinal cord in patients aged 55 years or older. Recent studies suggest that olive extracts suppress inflammation and reduce stress oxidative injury. The purpose of this study was to determine the potential neuroprotective effects of olive leaf extract (OLE) in an experimental cervical spondylotic myelopathy model.

Objectives: To study the antidiabetic and antioxidant activities of nipa palm vinegar (NPV) used in traditional Malay medicine for treating diabetes.

Methods: NPV was extracted using liquid-liquid extraction method and the obtained samples were subjected to antidiabetic studies using normal and streptozotocin-induced diabetic rat models whereas antidoxidant activities were investigated via in vitro antioxidant tests namely 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azinobis-3-ethylbenzothiozoline-6-sulfonic acid free radicals scavenging activities and the reducing power assay.

Results: Single administration of NPV and its extracts were not effective in both normal and diabetic rats.
