CONCLUSION: Reproductive-aged women’s specific knowledge of the benefits and risks of intrauterine contraception is limited. More educational interventions are needed to increase women’s knowledge about the effectiveness and benefits of intrauterine contraception.

“The article presents the melanogenesis pathway and the role of cyclic adenosine monophosphate (cAMP) and microphthalmia transcription factor (MITF) in IPI145 regulation of this process. Products of melanogenesis are eu-and/or pheomelanins synthesized in a multistage process of tyrosine oxidation and polymerization. The conversions require the presence of tyrosinase

(TYR, key enzyme), tyrosine hydroxylase isoform I (THI) and tyrosinase related proteins (TRP1 and TRP2). Many types of signal molecules ACY-738 chemical structure and transcription factors participate in regulation of melanin synthesis, but the most important are cAMP and MITF. cAMP is the second messenger in the intracellular signal cascade, which is synthesized

from adenosine triphosphate (ATP) by adenylyl cyclase, activated among others by the melanocortin receptor and the alpha(S) subunit of G protein. The signal molecule cAMP regulates MITF, TYR, THI, GTP-cyclohydroxylase I (GTP-CHI) transcription and phenylalanine hydroxylase (PAH) phosphorylation at Ser(16) by protein kinase A (PKA). Mutations of genes encoding proteins belonging to the cAMP signal cascade may lead to McCune-Albright and Carney syndromes. MITF is one of the most important nuclear transcription factors regulating melanogenesis. Currently 10 isoforms of human MITF are known, but in melanocytes only MITF-M, MITF-Mdel, MCC950 research buy MITF-A and MITF-H occur. MITF transcription factor regulates melanogenesis by activation of tyrosinase, TRP1 and TRP2 transcription. It also affects expression of other factors regulating melanosome maturation, biogenesis and transport. Moreover, it regulates melanocyte proliferation and protection against apoptosis. Mutations of the MITF gene may lead to

hereditary diseases: Waardenburg type II and Tietz syndromes.”
“The effect of alkali viz., sodium hydroxide and potassium hydroxide, on the recovery of xylan from sugarcane bagasse under two different conditions namely overnight incubation at room temperature and autoclaving was investigated. Conditions for the enzymatic cleavage of the extracted xylan leading to the best yields of xylooligosaccharides was investigated using a fixed substrate concentration (2%, w/v) and varied inputs of other critical factors like pH, temperature, enzyme dose and reaction time. The sugarcane bagasse constituted of 98.99 +/- 0.01% organic matter, 35.67 +/- 0.15% cellulose, 23.22 +/- 0.05% hemicellulose, 6.04 +/- 0.06% lignin and 2.3 +/- 0.01% protein. The highest xylan recovery of 85% was attained using 12% sodium hydroxide combined with steam application.
