The study examined the relationship between class I HLA antigens and type II diabetes with regard to insulin secretion and hyperlipoproteinemia. Out of 28 HLA antigens of A, B and C loci, 46 type II diabetics had statistically more significant HLA Cw1 - 15.9% as compared with 6.3% of the control group, the relative risk being 2.81. These patients were younger than the other diabetics but showed no difference in insulin secretion or hyperlipoproteinemia. Diabetics with HLA Cw4, just as patients after myocardial infarction with concomitant hyperlipoproteinemia, were also found frequently to have hyperlipoproteinemia (89 percentage cases as compared to 63% of the other diabetics). The findings may be indicative of potential genetic heterogeneity of type II diabetes. The paper stresses the necessity of establishing suitable genetic characters for early diagnosis of diabetes and its development.

Hepatic fibroblasts comprise groups of stromal cells in the liver that are phenotypically distinct from hepatic stellate cells. However, their physiology is poorly understood. By single-cell RNA sequencing, we identified Cd34 and Dpt as hepatic fibroblast-specific genes.

Background: Some cancers have been found to require abundant supplies of lipids for their development. One example is prostate cancer (PCa). To date, lipid-modifying factors, such as proprotein convertase subtilisin/kexin type 9 (PCSK9), angiopoietin-like 3 protein (ANGPTL3), and lipoprotein(a) or Lp(a), have not been reported in men with PCa.

Unlabelled: Human T-cell leukemia virus type 1 (HTLV-1) induces chronic long-term latent infection that can cause fatal diseases, including adult T-cell leukemia. HTLV-1 production is poor and undetectable during the asymptomatic phase of infection. Virus-host immune interaction in latent infection has not been fully determined.

Six Gram-reaction-positive, strictly aerobic, mycelium-forming actinobacteria were isolated from soils collected from a natural cave in Jeju, Republic of Korea. The isolates produced well-developed, branched, substrate mycelia and white aerial mycelia that differentiated into straight or flexuous chains of smooth-surfaced spores. Cells showed growth at 15-30 °C, pH 3.
