Poly(alkyl-terphenyl piperidinium) ionomers and membranes were used for H2–O2 anion exchange membrane fuel cells, achieved a high power density of 2.58 W cm−2, which is new record polyaromatic-based cells. Details the study are described by Young Moo Lee co-workers in their Research Article on page 7710.
Liquid half-cell measurements provide a convenient laboratory method for the determination of relevant parameters electro-catalysts applied in e.g. polymer electrolyte membrane fuel cells. While these may be effective...
Radical-induced degradation of proton exchange membranes limits the durability proton-exchange membrane fuel cells. Cerium is widely used as a radical scavenger, but migration cerium ions to the...
for the present study, and follow-up of histochemical changes in estradiol valerate-induced polycysticovary syndrome (pcos), 48 virgin 90-day-old female rats were used. the rats were divided into thetreatment and control groups. for each rat of the treatment group, 4 mg estradiol valerate was injectedthrough intramuscular route for the induction of pcos. the control group was taken the same amo...
Concentrated growth factors are extracted from platelet-rich plasma obtained healthy adult veins by physical gradient centrifugation, and the activated platelets release various cytokines, which can be further converted into concentrated liquid or gel preparations different centrifuge tubes. These widely used in clinical treatments fields, such as dentistry, dermatology surgery. In this article...
The Hutchinson-Gilford syndrome or progeria is a laminopathy generated by mutations that affect LMNA gene. This produces an abnormal protein named progerine which alters the formation of the cellular membrane inducing premature aging of all cells. In the present review aspects related to the pathophysiology and clinical characteristics of this syndrome are shown.
Abstract Biomembranes experience out-of-equilibrium conditions in living cells. Their undulation spectra are different from those thermal equilibrium. Here, we report on the of a fluid membrane pushed by stepwise growth filaments as leading edge migrating cells, using three-dimensional Monte Carlo simulations. The undulations largely modified equilibrium behavior. When tension is constrained, l...
Chronic epidermal wounds that do not heal within 30 days afflict nearly 8.2 million patients across the country, costing US healthcare system up to $96 billion annually. Electrical stimulation (ES) of skin speeds healing chronic despite absence specific mechanisms. We are testing hypotheses understand mechanisms by which non-excitable cells involved with wound sense these EFs. For comparison, h...
Testis is the male reproductive organ that performs both endocrine and exocrine functions. This study aimed to determine distribution of carbohydrates in testis sumba ongole cattle. The sample consisted six were collected from East Sumba Slaughter House, fixed formalin 10 %, processed histologically, continued with AB pH 2,5 - PAS staining. result showed a weak alcian blue intensity (+) tunica ...
Milk thistle (Silybum marianum) is a native plant of Mediterranean Sea areas. Silymarin, an extract from its seeds, is used in various liver diseases for its hepatoprotective effects. It contains silymarin flavonoids (SF) such as silybin, silydianin and silychristin. Cyclosporin A (CsA) is widely used as an immunosuppressant in organ transplantations. Its other applications in many autoimmune d...
