Macroanatomy and 3-dimensional modeling of the tentacular head of Phascolosoma arcuatum (Grey, 1828)
No full textAbstract: The macroanatomy of the tentacular head of Phascolosoma arcuatum belongs to phylum Sipuncula has been studied under light microscopic methods and computer aided graphics analysis. The tentacular head structure has been reconstructed using computer aided graphics analysis using series histological images on computer aided software platform. The P. arcuatum has only five, semitransparent, pigmented, lobed tentacles in tentacular crown with large tentacular coelomic connections. We found that the tentacles are lined by ciliated columnar epithelium with large number of mucosecretory cells, indicating their deposit feeding habit. Fewer number of tentacles, body wall and there burrowing habit supports there integumentary breathing habit. A thick striated collar encircles the tentacles forming the ventral wall of the mouth channel and protects tentacles from mechanical damage when retracted. These structural peculiarities revealed from macroanatomical analysis are strongly suggestive about the important role of the collar region of the tentacular crown of the head of P. arcuatum in relation to its burrowing habit to its concern habitat.

Effective Load Distribution Algorithm Considering Power and Interference Mitigation In A Dense Femtocell Based Network
No full textAbstractThis paper focuses on effective load distribution in a dense femtocell network. For densely deployed femtocell network, interference and power consumption are of big concern. There may be situations such as while covering a single UE (User Equipment), a femtocell interferes its neighbor cells badly. In such cases, if the UE is handed over to the neighbor cell with higher load, it is still capable of covering the UE. Then the interference can be mitigated leaving one cell empty. As femtocells are self configurable, an empty cell can change its state to standby mode; thus reducing the power consumption as well as interference. We have proposed an algorithm based on the load of a cell as well as its neighbor cells and SINR (Signal to Interference and Noise Ratio) of a UE for the cells. The proposed algorithm will assign a UE optimally choosing a FAP (Femtocell Access Point) or femtocell based on the load and SINR values

No full textAbstract
The research objectives of this study are to analyze the effectiveness of committee and mechanism of corporate governance to prevent financial crime. Financial Crime often occur inside the company, especially in Indonesia. Financial crime covers fraud, money laundering, bribe, corruption, terrorist financing and so on. At 2018, there’s case where PT. Garuda Indonesia committed revenue recognition fraud by recognizing revenue amounted to USD 239 million from Mahata Aero Teknologi which is yet to be received by the end of 2018. The company’s management and external audit are fined for the negligent in preventing the fraud. Therefore, the effectiveness of company’s organizational structure played a big role to supervise and prevent the occurrence of financial crimes. In this discussion, the author investigates the effectiveness of audit committee, board of commissioners, stand-alone risk committee, external audit, effect of managerial ownership and company’s performance toward financial crime. Data for the research were collected from secondary data found in annual report of 426 companies and analyzed using logistic regression method using SPSS 25. The study findings prove that stand-alone risk committee, external audit, and company’s performance have a significant negative effect toward financial crime, while size of audit committee have a significant positive effect toward financial crime. Research show that meeting frequency of audit committee, board of commissioners, and managerial ownership has no significant effect toward financial crim
Ross syndrome: a case report
No full textRoss syndrome is a rare partial dysautonomic syndrome of unknown aetiology, characterized by segmental hypo/ anhidrosis associated with Holmes-Adie syndrome (tonic pupil and hypo/areflexia). The hypohydrosis or anhydrosis is patchy initially, later it becomes segmental or diffuse. This is due to affection of postganglionic cholinergic parasympathetic and sympathetic fibers involvement. There are a very few cases (approximately 50) have been reported in the literature since its original description. Author report a 22 years old male with classical features of Ross syndrome
Programmable human histone phosphorylation and gene activation using a CRISPR/Cas9-based chromatin kinase
No full textHistone phosphorylation is a ubiquitous post-translational modification that allows eukaryotic cells to rapidly respond to environmental stimuli. Despite correlative evidence linking histone phosphorylation to changes in gene expression, establishing the causal role of this key epigenomic modification at diverse loci within native chromatin has been hampered by a lack of technologies enabling robust, locus-specific deposition of endogenous histone phosphorylation. To address this technological gap, here we build a programmable chromatin kinase, called dCas9-dMSK1, by directly fusing nuclease-null CRISPR/Cas9 to a hyperactive, truncated variant of the human MSK1 histone kinase. Targeting dCas9-dMSK1 to human promoters results in increased target histone phosphorylation and gene activation and demonstrates that hyperphosphorylation of histone H3 serine 28 (H3S28ph) in particular plays a causal role in the transactivation of human promoters. In addition, we uncover mediators of resistance to the BRAF V600E inhibitor PLX-4720 in human melanoma cells using genome-scale screening with dCas9-dMSK1. Collectively, our findings enable a facile way to reshape human chromatin using CRISPR/Cas9-based epigenome editing and further define the causal link between histone phosphorylation and human gene activation.Fondren Library Open Access Author Fun
Tridentate NacNac Stabilized Tin and Nickel Complexes: Access to a Monomeric Nickel Hydride and Its Catalytic Application

nacnac
germylene monochloride [2,6-iPr2–C6H3NC(Me)CHC(Me)NH(CH2py)]GeCl (1) (py = pyridine) with SnCl2 results in an analogous
stannylene chloride (2). The three-coordinated stannylenium
cation [{2,6-iPr2–C6H3NC(Me)CHC(Me)NH(CH2py)}Sn]+ with
SnCl3– as a counteranion (3) has been generated through the abstraction of chloride ligand from 2 using an additional equivalent of SnCl2. Instead
of forming a donor–acceptor complex, 2 undergoes
a facile redox transmetalation reaction with Ni(COD)2 (COD
= cyclooctadiene) and CuCl to afford analogous nickel and copper complexes
[2,6-iPr2–C6H3NC(Me)CHC(Me)NH(CH2py)]MCl [M = Ni (4) and
Cu (5)]. The reactions of 4 with potassium
tri-sec-butylborohydride (commonly known as K-selectride)
and AgSbF6 provide access to monomeric Ni(II) hydride,
[2,6-iPr2–C6H3NC(Me)CHC(Me)NH(CH2py)]NiH (6) and a Ni(II)
cation, [{2,6-iPr2–C6H3NC(Me)CHC(Me)NH(CH2py)}Ni][SbF6] (7), respectively. 6 was found to be
an effective catalyst for the hydroboration of amides
