Effective exosomes in breast cancer: focusing on diagnosis and treatment of cancer progression.

Breast cancer (BC) is the most prevalent aggressive malignant tumor in women worldwide and develops from breast tissue. Although cutting-edge treatment methods have been used and current mortality rates have decreased, BC control is still not satisfactory. Clarifying the underlying molecular mechanisms will help clinical options. Extracellular vesicles known as exosomes mediate cellular communication by delivering a variety of biomolecules, including proteins, oncogenes, oncomiRs, and even pharmacological substances. These transferable bioactive molecules can alter the transcriptome of target cells and affect signaling pathways that are related to tumors. Numerous studies have linked exosomes to BC biology, including therapeutic resistance and the local microenvironment. Exosomes' roles in tumor treatment resistance, invasion, and BC metastasis are the main topics of discussion in this review.

Analysis of serum glutamic pyruvic transaminase and serum glutamic oxaloacetic transaminase levels in tuberculosis patients who are undergoing oat treatment in Kendari City General Hospital, Kota Kendari, Indonesia.

In the treatment of tuberculosis (TB), the patient is generally directly given Anti Tuberculosis Drugs (Obat Anti Tuberculosis/OAT) without examining Serum Glutamic Pyruvic Transaminase (SGPT) and Serum Glutamic Oxaloacetic Transaminase (SGOT) to see whether or not there is liver damage before treatment. Because of the side effects by OAT, it is important to know how the condition of the liver function of TB patients who consume OAT in Kendari City General Hospital (Rumah Sakit Umum Daerah/RSUD) Kota Kendari by looking at SGOT and SGPT levels in order to provide maximum treatment to TB patients. The method of this research was descriptive analysis with cross sectional approach. The sample is all patients had previously been diagnosed with TB by a doctor based on medical records by in RSUD Kota Kendari after 1-2 months OAT treatment without any sign of liver injury before. Examination of SGOT and SGPT levels was performed on all samples in the Laboratory of RSUD Kota Kendari using clinical chemistry analyzer. The results of this study showed that 20% patients with TB had elevated levels of SGPT and SGOT with average SGOT is 51 U/L and SGPT is 42.5. The Inference of this study that there is an increase in SGOT and SGPT levels in patients who consume OAT 1-2 months in RSUD Kota Kendari. Elevated levels of SGPT and SGOT due to Anti Tuberculosis (OAT) drugs did not occur in all patients and only increased in 3 people, but qualitatively the effect of administering anti-tuberculosis drugs significantly increased levels of SGPT and SGPT. Thus, monitoring of liver physiology remains recommended especially for elderly patients.

The antibacterial activity of Tembelekan leaf (Lantana camara L.) and Kopasanda leaf (Chromolaena odorata L.) extracts against Staphylococcus aureus.

Staphylococcus aureus (S. aureus) is a round-shaped Gram-positive bacteria that caused infection in the human body. S. aureus infection can be inhibited by the use of antibiotics. However, these bacteria displayed resistance to some antibiotics. The purpose of this study is to determine the effects of Tembelekan (Lantana camara L.) and Kopasanda (Chromolaena odorata L.) leaf extracts against S. aureus. The method used in this study is the disc method to determine the inhibition zone. The test results showed there was no significant difference in the sensitivity of Tembelekan leaf extract (L. camara L.) and Kopasanda leaf extract (C. odorata L.) against S. aureus (P0.8>α0.05). However, based on the average value of the inhibition zone, Kopasanda leaf extract was showed higher inhibition zone compared to Tembelekan leaf extract. In conclusion, Tembelekan leaf and Kopasanda leaf at a concentration of 100% were produced inhibition zones of 0.6 cm and 0.8 cm respectively against S. aureus.
