The vertebrate photoreceptor provides a drammatic example of cell polarization. Specialized to carry out phototransduction at its distal end and to synapse with retinal interneurons at its proximal end, this long slender cell has a uniquely polarized morphology which is reflected in a similarly polarized cytoskeleton. Membranes bearing photopigment are localized in the outer segment, a modified sensory cilium. Sodium pumps which maintain the dark current critical to photosensory transduction are anchored along the inner segment plasma membrane between the outer segment and the nucleus.Proximal to the nucleus is a slender axon terminating in specialized invaginating synapses with other neurons of the retina. Though photoreceptor diameter is only 3-8u, its length from the tip of the outer segment to the synapse may be as great as 200μ. This peculiar linear cell morphology poses special logistical problems and has evoked interesting solutions for numerous cell functions. For example, the outer segment membranes turn over by means of a unique mechanism in which new disks are continuously added at the proximal base of the outer segment, while effete disks are discarded at the tip and phagocytosed by the retinal pigment epithelium. Outer segment proteins are synthesized in the Golgi near the nucleus and must be transported north through the inner segment to their sites of assembly into the outer segment, while synaptic proteins must be transported south through the axon to the synapse.The role of the cytoskeleton in photoreceptor motile processes is being intensely investigated in several laboratories.

ABSTRACT Several drugs from the morphine, pethidine and morphinan series were evaluated with respect to their action on the pituitary secretion of thyrotrophin (TSH). This action was measured by the release and the uptake of 131I by the thyroid gland of mice. Daily administration of 500 μg of morphine, codeine, dihydromorphinone, levorphan, dextrorphan or meperidine significantly depressed the uptake of 131I by the thyroid gland within five days. Single injections of 500 μg of either dihydromorphinone or levorphan increased the thyroidal uptake of 131I The thyroids of hypophysectomized mice, pretreated with 131I and thyroxine, failed to respond to injections of these drugs. Daily administration of these drugs for five days failed to change pituitary content of TSH from the control level, or to effect a change in the turn-over rate of exogenous radiothyroxine. These results suggest that these drugs do not exert direct action on the thyroid but act on thyroid function through their effect on the hypothalamus-pituitary axis.

Laporan keuangan tahunan suatu koperasi dapat memberikan informasi sehubungan dengan kondisi keuangan dan hasil yang telah dicapai koperasi tersebut. Untuk mengetahui dan menilai kinerja koperasi dalam proses mencapai tujuannya diperlukan metode pengukuran terhadap kinerja keuangan koperasi itu sendiri. Penelitian ini dilakukan dengan tujuan untuk mengetahui kinerja keuangan Koperasi Dosen dan Karyawan (KDK) Sekolah Tinggi Ilmu Ekonomi Indragiri (STIE-I) Rengat selama periode 2014 – 2018. Analisis yang digunakan dalam mengukur kinerja keuangan Koperasi Dosen dan Karyawan STIE Indragiri dengan menggunakan sistem Du-Pont. Analisis dengan sistem Du-Pont memfokuskan pengukuran pada Return on Invesment (ROI) yang merupakan integrasi dari pengukuran Net Profit Margin dan Asset Turnover. Data yang digunakan dalam penelitian ini adalah data laporan keuangan yang berupa neraca dan laporan laba/rugi periode tahun 2014 sampai dengan 2018. Hasil analisis yang dilakukan menunjukkan Total Aktiva, Modal, Pendapatan dan Laba Bersih cenderung mengalami peningkatan dan pertumbuhan yang positif (surplus) kecuali pada sisi laba bersih, dimana laba bersih pada akhir periode 2016 tidak mengalami pertumbuhan. Indeks pertumbuhan NPM tertinggi diperoleh pada periode 2015 dan 2018 yaitu sebesar 1,25 dan indek pertumbuhan NPM terendah terjadi pada periode 2016 yaitu sebesar 0.37. Total Asset Turn Over (TATO), atau perputaran total aktiva tertinggi terjadi pada periode 2016 dengan Indeks sebesar 1 dan terendah pada periode 2015 sebesar 0,50. Return On Invesment (ROI) indeks pertumbuhan tertinggi terjadi di periode tahun 2018 yaitu pada angka indeks 1,10 dan terendah tahun 2016 yaitu pada indeks sebesar 0,39. Dilihat dari pertumbuhannya hal ini mengindikasikan bahwa manajemen KDK-STIE Indragiri sudah mampu memberikan kinerja yang baik

: The global burden of neurodegenerative diseases is alarmingly increasing in parallel to the aging of population. Although the molecular mechanisms leading to neurodegeneration are not completely understood, excitotoxicity, defined as the injury and death of neurons due to excessive or prolonged exposure to excitatory amino acids, has been shown to play a pivotal role. The increased release and/or decreased uptake of glutamate results in dysregulation of neuronal calcium homeostasis, leading to oxidative stress, mitochondrial dysfunctions, disturbances in protein turn-over and neuroinflammation. : Despite the anti-excitotoxic drug memantine has shown modest beneficial effects in some patients with dementia, to date, there is no effective treatment capable of halting or curing neurodegenerative diseases such as Alzheimer’s disease, Parkinson disease, Huntington’s disease or amyotrophic lateral sclerosis. This has led to a growing body of research focusing on understanding the mechanisms associated with the excitotoxic insult and on uncovering potential therapeutic strategies targeting these mechanisms. : In the present review, we examine the molecular mechanisms related to excitotoxic cell death. Moreover, we provide a comprehensive and updated state of the art of preclinical and clinical investigations targeting excitotoxic- related mechanisms in order to provide an effective treatment against neurodegeneration.
