In the present study, we compared the real-time reverse-transcription polymerase chain reaction (RT-PCR) and total IgM-IgG antibody tests for diagnosis SARS-CoV-2 patients. SARS-CoV-2 patients were divided into four additional subgroups according to clinical examination, and Computed Tomography (CT) for SARS-CoV-2. Groups were included 60 mild cases, 111 moderate cases, 53 severe cases, and 105 normal cases. In a mild group, 52.5% of 60 cases were found to be male, 45.9% female, and the average age was found as 38.4 Â±2.011. The positive ratio was found as 80.3% in the RT-PCR test, while 39.3% in total IgM/IgG. In a moderate group, 49.1% of 111 cases were found to be male, 50% female, and the average age was 45.05 Â±1.519. The positive ratio was found as 85.7% in the RT-PCR test while 54.5% in total IgM/IgG. In a severe group, 53.7%of 53 cases were found to be male, 44.4% female, and the average age was 55.5Â±2.122. The positive ratio was found as 75.9% both in RT-PCR and total IgM/IgG tests. In a normal group with no involvement according to Computed Tomography (CT), 49.1%of 105 cases were found to be male, 50% female, and the average age was found as 34.8Â±1.391. The positive ratio was found as 95.3% in the RT-PCR test while 5.7% in total IgM/IgG. Chronic diseases were detected more in severe cases, suggesting that persons who have chronic diseases or decreased immunity, such as diabetes mellitus, cardiovascular diseases, hypertension, and lung disease, are at a higher risk for developing severe COVID-19 if they are infected with SARS-CoV-2. According to our results, we can suggest a higher detection sensibility in RT-PCR than in total IgM/IgG antibody test for mild, moderate and normal group, while the detection sensibility of IgM/IgG antibody increases in a severe group with bilateral diffuse involvement according to CT.

Methicillin-Resistant Staphylococcus aureus (MRSA) infections have created a critical need for the development of natural antibacterials from biological sources. This research aimed to investigate the antibacterial activity of the seed extract of three-member Artocarpus (Artocarpus heterophyllus, A. champeden and A. camansi) against MRSA which are the most prevalent causes of infections in patients. Crude seed extracts of three-member Artocarpus were evaluated for their antibacterial activity against MRSA. The antibacterial activity against MRSA of the three extracts was assayed in vitro by the agar well diffusion assay and agar microdilution method (Minimum inhibitory concentration [MIC] and Minimum bactericidal concentration [MBC]). The best antibacterial activity, calculated as a zone of inhibition and MIC, MBC values. The Crude seed extracts of three-member Artocarpus showed antibacterial activity against the MRSA in the agar well diffusion assay (1.5-9 mm inhibition diameter). The MIC value of extract showed at 15.62 mg/mL and the MBC value of seed extract of A. heterophyllus at 62.5 mg/mL, A. champeden at 31.25 mg/mL, A. camansi at 250 mg/mL. The data have revealed that all seed extracts have the potential to be developed as antibacterial agents, particularly against MRSA strain. Further in vivo research and discovery of mode action are needed to shed light on their antibacterial effects. Research on anti-MRSA of seed extract of Artocarpus against MRSA has not been reported. Studies on the antibacterial activity against MRSA can provide new information about the benefits seed of members of Artocarpus as a source of natural antibacterial.

Congenital toxoplasmosis can cause damage and death to the fetus, to prevent this case, toxoplasmosis testing is important for the woman of childbearing age. One of the methods to screening the presence of T. gondii in the blood is Polymerase Chain Reaction (PCR). One of the T. gondii genes which can be used as a marker is the B1 gene. There are many toxoplasmosis cases in Indonesia, but the data is still difficult to find in West Bandung Regency. This study aimed to determine the number of toxoplasmosis cases in a woman of childbearing age in West Bandung Regency using the B1 gene as a marker and to determine the factors that influence these cases by conducting statistical analysis on the results of the questionnaire. The sample used in this study was 50 women of childbearing age (got married and domiciled in West Bandung). All samples have met the inclusion criteria and signed the informed consent. DNA from blood specimens was isolated using the Wizard Genomic DNA Purification Kit. The concentration and purity of isolated DNA were measured using a nanodrop device. Besides, the B1 gene from T. gondii was amplified using a pair of specific primers and visualized by the agarose electrophoresis method. Data were analyzed using the logistic regression method. The results showed that 7 women of childbearing age women (14%) in West Bandung Regency had toxoplasmosis. Frequent contact with pets, especially cats, was a significant factor (p <0.005) in this disease transmission.

The samples used for forensic DNA analysis in living individuals are usually blood and buccal swabs, however, blood collection requires an invasive method that can cause discomfort, thus a buccal swab can be a good choice for individuals examined, especially children. This study aimed to determine the effect of temperature and storage time of buccal swabs on the quantity of DNA as material for DNA examination in the forensic field. This study was a laboratory experiment to determine the effect after treatment. Buccal swab samples were 48 and divided into 2 temperature groups, namely room temperature (RT) and 4â„ƒ. The division of the temperature groups was also observed with time differences, namely 1, 3, 5, 7 days. EDNA extraction used the DNAzol method and DNA quantification used a Spectrophotometer. The PCR process was carried out with STR primers FGA and D13S317 loci. The visualization stage used acrylamide gel and silver staining. The results of this study prove that there is an effect of temperature and storage time of buccal swab samples. The longer the treatment time, the lower the DNA level. With statistical analysis, it is obtained p-value of <0.005, it can be concluded that there are significant differences in DNA levels at the temperature and storage time treatments of the buccal swab sample. The results of DNA visualization at the FGA and D13S317 loci using the STR PCR method in this study can still be detected and can be used as a reference for examination in forensic cases.

This research is to investigate the parameters which may affect the mobilization of stem cells in patients receiving autologous hematopoietic peripheral blood stem cell transplantation (PBSCT). A retrospective study was carried out using the data derived from the medical files of 242 patients who received PBSCT. Descriptive, clinical, and laboratory parameters were compared between patients with successful and unsuccessful stem cell mobilization. Successful stem cell mobilization ratio was 4.463 times higher when preemptive plerixafor was administrated; 1.032 times higher when CD34+ cell count increased 1 unit at the beginning of mobilization. The white blood cell count was inversely correlated with the success of mobilization. An increase of 1 unit in WBC count was associated with a 1.027 times decrease in the success rate. The data indicated that the administration of preemptive plerixafor and CD34+ cell count at the beginning of mobilization were directly related to the success of mobilization after PBSCT. On contrary, WBC count was inversely associated with the success rate.

Treatment of infections using penicillin-derived antibiotics such as methicillin has been found to cause antibiotic-resistant bacteria. This bacteria could produce a beta-lactamase enzyme to form a resistant strain. Research on antibacterial activity continues to develop. Pomegranate (Punica granatum L.) was one of the herbal plants whose fruit has long been used for the treatment and prevention of various diseases. This study aimed to determine the potential inhibition of white pomegranate leaf extracts (Punica granatum L.) on the growth of Gram-negative bacteria including Escherichia coli Extended-Spectrum Beta-Lactamase (ESBL) strain and Gram-positive bacteria Staphylococcus aureus Methicillin-Resistant Staphylococcus aureus (MRSA) strain. White pomegranate leaf extract macerated with ethanol 96%, evaporated to obtain pure extracts made with a concentration of 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and with 100% tested with invitro diffusion method. It was found that the extract of white pomegranate leaves with 30% (10.00 Â± 0.0) concentration was able to inhibit the growth of positive Gram bacteria strains MRSA and the extract was unable to inhibit the growth of Escherichia coli bacteria strain ESBL.

Gender differences affect the frequency and course of many diseases. This study aimed to determine the gender distribution in HIV-infected patients and investigate the relationship between gender and immune response. The study included HIV-infected patients who followed up in our hospital in 2018. The patients were divided into HIV RNA negative patients (Group 1) and HIV RNA positive patients (Group 2). Patients with diseases that may affect the immune system and those using drugs that affect the immune system were excluded from the study. The evaluation was made of 549 patients, as 305 patients (45 females 14.75%) in Group 1 and 224 patients (23 females, 9.43%) in Group 2. When the CD4/CD8 ratio of male and female patients was compared in both groups, a lower rate was determined in females (0.71-0.58) than males (0.82-0.93). A negative correlation was determined between HIV RNA and the CD4/CD8 ratio in premenopausal females (p=0.045) and males (â‰¤45 years p=0.0001). Clinical studies of HIV infection have demonstrated better initial viremia control in females with primary infection, faster disease progression, and stronger immune activation than males for the same level of viral replication.

The current COVID-19 pandemic challenges not only the lack of awareness of the disease, but also the rapid diagnosis, the prediction of severe early disease, the clinical characterization of mortality and severity of patients, and the effective management that affects the global scale, resulting in low capacities of healthcare systems, the resilience of systems and global economics. Therefore, early differential diagnosis and prediction of SARS-COV-2 infection severity are needed. CRP and NLR are diagnostic markers commonly used, most available, effective, and economically used primarily to evaluate the ongoing systemic inflammatory response.
