Article Synopsis
  • Protamines are proteins vital for sperm chromatin condensation, with their expression ratios linked to fertility in different species.
  • The study aimed to evaluate RNA quality and protamine gene expression in testis samples from wild-derived mice, preserved under various conditions over different time frames.
  • Results indicated that samples preserved in RNAlater® or NAP buffer at -80°C maintained RNA integrity and protamine expression effectively, even under less optimal conditions like room temperature for a week.

Article Synopsis
  • Sentinel lymph node (SLN) mapping in epithelial ovarian cancer may lower risks from lymphadenectomy while still providing reliable diagnostic results; ongoing research aims to evaluate its effectiveness.
  • A systematic review of four studies involving 239 patients found SLN detection rates of 59.5% for pelvic and 64.4% for para-aortic regions, with technetium-99 showing better detection rates compared to indocyanine green.
  • Diagnostic accuracy for identifying lymph node metastasis was high, reaching 100% in the pelvic field and 98.1% for the para-aortic field, suggesting SLN mapping could be a valuable tool in this context.

: Hepatocellular carcinoma (HCC) is a leading global cause of cancer-related deaths. Thermal ablation techniques, especially radiofrequency ablation (RFA) and microwave ablation (MWA), have become pivotal treatments for HCC. This systematic review and meta-analysis aim to compare these modalities, highlighting their efficacy, strengths, and limitations in treating HCC.

Background: The molecule known as Interleukin-8 (IL-8), a chemotactic leukocyte, has been found to have a crucial role in the perpetuation of the inflammatory environment that is associated with hepatitis B virus (HBV) infection, as well as in the development of liver cirrhosis and cancer.

Objective: The aim of this study was to carefully examine the role of IL-8 in the inflammatory reaction and to compare the levels based on the severity of liver cirrhosis.

Methods: The study was conducted from February 2018 to September 2018 at the Gastroenterohepatology Division, Internal medicine Department, Faculty of Medicine, Universitas Sumatera Utara.

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.

Backgroud: Immune impairment, marked by increased expression of cytotoxic T lymphocyte antigen (CTLA)-4, promotes the disease progression of chronic hepatitis B.

Objective: This study aimed to determine the association between serum CTLA-4 level and disease progression in patients with chronic hepatitis B.

Methods: A cross-sectional study was conducted at Haji Adam Malik General Hospital Medan, Indonesia between October 2021 to September 2022.

Intensified pediatric chemotherapy regimens to treat adolescents and young adults (AYA) patients with Philadelphia negative acute lymphoblastic leukemia (ALL) have been associated with better outcomes. The local BFM 2009-based scheme complements the risk stratification assessing the measurable residual disease (MRD) along the induction phase with increasing levels of sensitivity. The present retrospective multicenter analysis included 171 AYA (15-40 years) patients treated accordingly between 2013 and 2019.

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a known complex, multi-organ system disorder with a sudden or subacute onset. ME/CFS occurs most commonly among women between 30 and 50 years of age. The current diagnostic criteria of ME/CFS, as defined by the Centers for Disease Control and Prevention, includes: profound fatigue and post-exertional malaise (>6 mo) unrelieved by rest, persistent cognitive impairment or orthostatic intolerance, and chronic unrefreshing sleep.

Background: Liver cirrhosis contributes to high liver-related mortality globally. Systemic inflammation mediated by immune cells contributes to the progression of liver cirrhosis. Growing evidence shows that several pro- and anti-inflammatory cytokines might have an important role in liver cirrhosis.

Despite myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) affecting millions of people worldwide, many clinicians lack the knowledge to appropriately diagnose or manage ME/CFS. Unfortunately, clinical guidance has been scarce, obsolete, or potentially harmful. Consequently, up to 91% of patients in the United States remain undiagnosed, and those diagnosed often receive inappropriate treatment.

Individuals with malignancies and COVID-19 have a lower survival compared with the general population. However, the information about the impact of COVID-19 on the whole hematological population is scarce. We aimed to describe the 30th day overall survival (OS) after COVID-19 infection in patients with a hematological disease in Argentina.

The presence and distribution of Rhyacophila fasciata Hagen 1859 in Europe were revised, based on bibliographic study, collection specimens, and new material collected in different countries. The status of formerly synonymized species, Rhyacophila ferruginea (Scopoli 1763) and Rhyacophila septentrionis McLachlan 1865 was also assessed. The type of R.

Treating an anticoagulated patient with vitamin K antagonists (VKA) remains a challenge, especially in areas where dicoumarins are still the first drug of choice due to the cost of other oral anticoagulants. Anticoagulation clinics have proven to be the most efficient and safe way to avoid thrombotic and hemorrhagic complications and to keep patients in optimal treatment range. However, they require adequate infrastructure and trained personnel to work properly.

The morphology of the different stages (larva, pupa, male, and female) of Rhyacophila fasciata kykladica Malicky Sipahiler 1993 was examined as a basis for the description of the taxon. Morphological data were supplemented by molecular analysis of mitochondrial cytochrome C oxidase subunit I (mtCOI), which were compared with samples of the nominate subspecies Rhyacophila fasciata fasciata Hagen 1859, as well as with other new species in this group, Rhyacophila denticulata McLachlan 1879 and Rhyacophila sociata Navás 1916. Our results revealed genetic differences between all the taxa; therefore, a change of taxonomic status of R.

Dysplasia is a precancerous lesion of colorectal cancer in patients with long-standing inflammatory bowel diseases (IBDs), such as ulcerative colitis and Crohn's disease. Recent guidelines suggest endoscopic resection as a key modality for the treatment of endoscopically resectable dysplasia in patients with colitis. Endoscopic submucosal dissection (ESD) has been suggested as one of the therapeutic options for dysplasia that is potentially resectable but not suitable for the conventional endoscopic mucosal resection technique.

Cells of the adaptive immune system recognize pathogenic peptides through specialized receptors on their membranes. The engagement of these receptors with antigen leads to cell activation, which induces profound changes in the cell including cytoskeleton remodeling and membrane deformation. During this process, receptors and signaling molecules undergo spatiotemporal reorganization to form signaling microclusters and the immunological synapse.

Social awareness aims to increase practical skills, such as sustainable development, which seeks to increase the use of different types of waste in construction activities. Although insufficient attention is sometimes given to these actions, it is essential to spread information regarding new studies in the field of waste recycling, which encourages and promotes waste use. Reusing and recycling construction waste in the creation of buildings and infrastructure are fundamental strategies to achieving sustainability in the construction and engineering sectors.
