Organ.c agriculture is in.reasin.ly used as an.altern.tive to con.en.ion.l agriculture due to its positive impact on.the health of ecosystems an. agroecosystems. However, the outcome of organ.c agriculture in.terms of the production.of various crops remain. un.ertain.due to the in.luen.e of man. variables, risin. question. about its advan.ages over con.en.ion.l agriculture. This study assessed the impacts of organ.c agricultural system on.arbuscular mycorrhizal (AM) fun.i diversity in.soil an. green.tomato (physalis ixocarpa Brot. ex Horn. crop production. A field experimen. was con.ucted usin. a ran.om block design.with five repetition. of the followin. treatmen.s: a) Con.rol (n. fertilization. n.);b) Vermicompost use (OTV);c) OTV with vermicompost leachin. (OTH);an. d) In.rgan.c fertilization.(CST). Throughout the crop cycle, soil samples were an.lyzed chemically, the relative growth rate (RGR) of the plan.s was measured, an. the colon.zation.an. diversity of AM fun.i were quan.ified in.roots an. soil;fin.lly, above-groun., root biomass, an. fruit production.were measured. Organ.c fertilization.(OTV, OTH) in.reased (p p > 0.05). It is con.luded that organ.c agriculture man.gemen. is essen.ial to promote a greater AM fun.i diversity an. fun.i root colon.zation. Plan.-AM fun.i in.eraction.in.reases growth rates an. it allows a similar tomato production.compared with con.en.ion.l agriculture.

Sebum production.is key in.the pathophysiology of acn., an.extremely common.con.ition. which when.severe, may require treatmen. with isotretin.in. a kn.wn.teratogen. Apart from isotretin.in.an. hormon.l therapy, n. agen.s are available to reduce sebum. In.reasin. our un.erstan.in. of the regulation.of sebum production.is a mileston. in.iden.ifyin. altern.tive therapeutic targets. Studies in.sebocytes an. human.sebaceous glan.s in.icate that agon.sts of peroxisome proliferator-activated receptors (PPARs) alter sebaceous lipid production. The goal of this study is to verify the expression.an. activity of PPARs in.human.skin.an. SEB-1 sebocytes an. to assess the effects of PPAR ligan.s on.sebum production.in.patien.s. To in.estigate the con.ribution.of each receptor subtype to sebum production. lipogen.sis assays were performed in.SEB-1 sebocytes that were treated with PPAR ligan.s an. isotretin.in. Isotretin.in.sign.fican.ly decreased lipogen.sis, while the PPARαagon.st-GW7647, PPARδagon.st-GW0742, PPARα/δagon.st-GW2433, PPARγagon.st rosiglitazon., an. the pan.gon.st-GW4148, in.reased lipogen.sis. Patien.s treated with thiazolidin.dion.s or fibrates had sign.fican. in.reases in.sebum production.(37 an. 77%, respectively) when.compared to age-, disease-, an. sex-matched con.rols. These data in.icate that PPARs play a role in.regulatin. sebum production.an. that selective modulation.of their activity may represen. a n.vel therapeutic strategy for the treatmen. of acn..

Certain.skin.disorders, such as con.act dermatitis an. chron.c urticaria, are characterized by in.lammation.in.olvin. mast cells an. worsen.by stress. The un.erlyin. mechan.sm of this effect, however, is n.t kn.wn. The skin.appears to have the equivalen. of a hypothalamic-pituitary-adren.l (HPA) axis, in.ludin. local expression.of corticotropin.releasin. hormon. (CRH) an. its receptors (CRH-R). We have reported that acute stress an. in.radermal admin.stration.of CRH stimulate skin.mast cells an. in.rease vascular permeability through CRH-R1 activation. In.this study, we in.estigated the expression.of CRH-R1, the main.CRH-R subtype in.human.skin. an. the mast cell related gen. histidin. decarboxylase (HdC), which regulates the production.of histamin., in.n.rmal an. pathological skin.biopsies. Quan.itative real time PCR revealed that chron.c urticaria expresses high levels of CRH-R1 an. HdC as compared to n.rmal foreskin. breast skin.an. cultured human.keratin.cytes. The lichen.simplex samples had high expression.of CRH-R1,but low HdC. These results implicate CRH-R in.chron.c urticaria, which is often.exacerbated by stress.
