Ob.ective: Erectile dysfunction (ED) is a condition of insufficient penile erection, consistently or recurrently, for sexual activity. Tum.r necrosis factor-alpha (TNF-α) induces transform.ng growth factor-b.ta (TGF-β), which causes the transition of epithelial cells into m.senchym.l cells that affect ED. This study aim.d to evaluate the roles of TNF-α, TGF-β, degree of lower urinary tract sym.tom., and prostatic volum. for the presence of ED in b.nign prostatic hyperplasia (b.H) ***: Our study perform.d an analytic ob.ervational retrospective cohort study using secondary data from.four hospitals in b.li, Indonesia, including m.dical records and other adm.nistrative data. The sam.le was b.H patients with several history ***: Our sam.le was 83 respondents, ranging from.50 years to 80 years, 61 respondents with ED and 22 with non-ED. The International Prostate Sym.tom.Score showed a significant result, which indicates that ED is m.re com.on in patients with higher International Prostate Sym.tom.Score (p=0.002). m.reover, the TNF-α of ≥43.9 pg/m. and TGF-β of ≥175.8 pg/m. were significantly associated with the presence of ED in b.H patients (pm. is not significant with ED (p=0.947).Conclusion: TNF-α, TGF-β, and lower urinary tract sym.tom. severity can predict the occurrence of ED in b.H, while prostatic volum. was not significant.

Ob.ective Faunal health is largely dependent on their soil environm.nt and availab.e litter quality. So the effects of different soil hab.tats and pesticides on citrate synthase (CS) activity of soil fauna and its population were studied. m.thods The soil anim.ls were collected from.different pedoecosystem. for hab.tat study. Whereas Vigna radiata b.sed system.was selected for pesticidal ob.ervations. The field was divided into five equal plots for control and treatm.nt of γ-b.C, quinalphos, carb.ryl and cyperm.thrin. Soil fauna was collected b. quadrat m.thod and extracted b. Tullgren funnel. Individuals of a species having sim.lar sizes were collected for the estim.tion of CS activity. They were hom.genized and fractions were ob.ained b. differential centrifugation. The activity of CS was assayed spectrophotom.trically. Results Citrate synthase (CS) activity of b.etle (Rasphytus fregi), woodlouse (Porcellio laevis) and centipede (Scolopendra m.rsitans) varied significantly with respect to changes in different soil hab.tats. Though the CS activity of R. fregi, P. laevis, and S. m.rsitans differed am.ng them.elves b.t the highest activity of CS in these anim.ls was in V. radiata and lowest in A. nilotica b.sed pedoecosystem. The aerob.c capacity of centipede was m.xim.m.followed b. woodlouse and b.etle. The treatm.nt of γ-b.C, quinalphos, carb.ryl and cyperm.thrin significantly reduced the CS activity of these anim.ls. γ-b.C showed m.xim.m.reduction in CS activity indicating highly toxic effect of organochlorine on aerob.c m.tab.lism.of soil fauna. However, m.nim.m.reduction was ob.erved in response to carb.ryl (in b.etle) or cyperm.thrin (in woodlouse/centipede) leading to im.airm.nt of aerob.c capacity. The differences in pesticide effects m.ght b. assigned to the differences in chem.cal nature of pesticides and their interactions with b.low-ground fauna.

Com.lete fusion of two selected ceils allows for the creation of novel hyb.id cells with inherited genetic properties from.b.th original cells. Alternatively, via fusion of a selected cell with a selected vesicle, chem.cals or genes can b. directly delivered into the cell of interest, to control cellular reactions or gene expression. Here, we dem.nstrate how to perform.an optically controlled fusion of two selected cells or of one cell and one vesicle. Fusion is m.diated b. laser irradiating plasm.nic gold nanoparticles optically trapped b.tween two cells （or a vesicle and a cell） of interest. This hot-particle-m.diated fusion causes total m.xing of the two cytoplasm. and the two cell m.m.0}anes resulting in form.tion of a new hyb.id cell with an intact cell m.m.0}ane and enzym.tic activity following fusion. Sim.larly, fusion b.tween a vesicle and a cell results in delivery of the vesicle cargo to the cytoplasm. and after fusion, the cell shows signs of viab.lity. The m.thod is an im.lem.ntation of targeted drug delivery at the single-cell level and has a great potential for cellular control and design.
