We evaluated the relative contribution of the humoral and cellular arms of the immune response to bone marrow cells transplanted into sensitized recipients. We report here for the first time that humoral immunity contributes predominantly to allosensitization. Although the major role for nonmyeloablative conditioning is to control alloreactive host T cells in nonsensitized recipients, strikingl...

The prevalent global energy crisis calls for searching viable pathways generating green hydrogen as an alternative resource. Dye-sensitized photocatalytic water splitting is a feasible solution to produce hydrogen. However, identifying suitable catalysts has been one of the bottlenecks in driving dye-sensitized photocatalysis efficiently. In this work, new class electrocatalysts reported based ...

objective: seeking for fertility after previous vasectomy is increasing. vasectomy may break the blood testis barrier and in this way the level of antisperm antibody increases. it is suggested that increase in antisperm antibody decreases spontaneous pregnancy even after successful vasovasostomy. in this study we evaluated antisperm antibody formation 3 months after vasectomy. method: this stud...

asthma is a global problem that affects over 300 million people in the world. the main reason of asthma is allergy and atopy. asthmatic patients are sensitized to allergens that can be resulting asthma attacks. fungi as an allergen can be sensitized atopic people and present a severe asthma. fungi have been found in water-damaged homes of asthmatic patients. allergic asthma is associated with e...

dye sensitized solar cell was fabricated from a double layer photoanode. first, tio2 nanoparticles  were synthesized by hydrothermal method. these tio2 nps were deposited on fto glasses by electrophoretic deposition  method in applied voltage of 5 v and epd time of 2.5-10 min. then tio2 hollow spheres (hss) were synthesized by sacrificed template method with carbon spheres as template and ttip ...

BackgroundOral immunotherapy (OIT) aims to establish desensitization and sustained unresponsiveness (SU) in patients with food allergy by ingestion of gradually increasing doses specific allergens. However, little is known about the mechanisms which OIT induces SU allergens.ObjectivesWe investigated role Notch signaling, controls cell fate decisions many types immune cells induction treatment.M...

BACKGROUND Although the levels of immunoglobulin E (IgE) in the circulating blood are often elevated in patients with allergic diseases, such levels cannot always be considered as pathognomonic signs of allergy. The induction of allergic reactions in the tissue was inferred to be related to the amount of IgE passing through the vascular wall. AIMS We attempted to clarify which compartment, th...

Energi radiasi matahari merupakan energi yang sedang giat dikembangkan saat ini. Indonesia negara sangat berpotensi untuk mengembangkan sel surya dikarenakan letak posisi berada di wilayah garis khatulistiwa (tropis). Sel alat mampu merubah sinar menjadi listrik. Teknologi telah ini adalah Dye Sensitized Solar Cell. menggunakan bahan kaca Indium Tin Oxide, dye titanium dioxide, cairan elektroli...

previous studies have indicated relaxant, inhibitory effect on histamine (h1) and muscarinic receptors, and stimulatory effect on β-drenoceptor of crocus sativus on guinea pig tracheal chains. in the present study, the effect of the extract of c. sativus and one of its constituents, safranal, on the inflammatory changes of sensitized guinea pigs was examined. eight groups of sensitized guinea p...

the acetone sensitized photolysis of the title compound gave 2-(2- oxopropy1)-9,9- dimethyl bicyclo [3.3.l]nona-3-one. a bridgehead cyclopropane intermediate was then suggested for the formation of the photoproduct
