Notch Signaling Activation Promotes Seizure Activity in Temporal Lobe Epilepsy
Notch signaling in the nervous system is often regarded as a developmental pathway. However, recent studies have suggested that Notch is associated with neuronal discharges. Here, focusing on temporal lobe epilepsy, we found that Notch signaling was activated in the kainic acid (KA)-induced epilepsy model and in human epileptogenic tissues. Using an acute model of seizures, we showed that DAPT, an inhibitor of Notch, inhibited ictal activity. In contrast, pretreatment with exogenous Jagged1 to elevate Notch signaling before KA application had proconvulsant effects. In vivo, we demonstrated that the impacts of activated Notch signaling on seizures can in part be attributed to the regulatory role of Notch signaling on excitatory synaptic activity in CA1 pyramidal neurons. In vitro, we found that DAPT treatment impaired synaptic vesicle endocytosis in cultured hippocampal neurons. Taken together, our findings suggest a correlation between aberrant Notch signaling and epileptic seizures. Notch signaling is up-regulated in response to seizure activity, and its activation further promotes neuronal excitation of CA1 pyramidal neurons in acute seizures
Labour Market and Social Policy in Italy: Challenges and Changes. Bertelsmann Policy Brief #2016/02
vEight years after the outbreak of the financial crisis, Italy has still to cope with and
overcome a plethora of economic and social challenges. On top of this, it faces an
unfavourable demographic structure and severe disparities between its northern and
southern regions. Some promising reforms have recently been enacted, specifically
targeting poverty and social exclusion. However, much more remains to be done on
the way towards greater economic stability and widely shared prosperity
Leibniz algebras constructed by Witt algebras
We describe infinite-dimensional Leibniz algebras whose associated Lie
algebra is the Witt algebra and we prove the triviality of low-dimensional
Leibniz cohomology groups of the Witt algebra with the coefficients in itself
Quasiparticle Liquid in the Highly Overdoped Bi2212
We present results from the study of a highly overdoped (OD) Bi2212 with a
K using high resolution angle-resolved photoemission spectroscopy.
The temperature dependent spectra near the () point show the presence of
the sharp peak well above . From the nodal direction, we make comparison
of the self-energy with the optimally doped and underdoped cuprates, and the
Mo(110) surface state. We show that this OD cuprate appears to have properties
that approach that of the Mo. Further analysis shows that the OD has a more
-independent lineshape at the Fermi surface than the lower-doped cuprates.
This allows for a realistic comparison of the nodal lifetime values to the
experimental resistivity measurements via Boltzmann transport formulation. All
these observations point to the validity of the quasiparticle picture for the
OD even in the normal state within a certain energy and momentum range.Comment: 4 pages, 4 figure
KAJIAN KEDUDUKAN DAN NILAI PEMBUKTIAN SAKSI MAHKOTA SEBAGAI ALAT BUKTI DALAM PEMBUKTIAN TINDAK PIDANA KORUPSI (STUDI KASUS NO.REG.PERK : PDS-01/SKRTA/Ft.1/03/2010 BERKAIT KORUPSI DI RUMAH SAKIT JIWA DAERAH SURAKARTA)
Penulisan penelitian hukum ini bertujuan untuk mengetahui dasar hukum
menurut jaksa penuntut umum digunakannya saksi mahkota serta kedudukan dan
nilai pembuktian saksi mahkota dalam pandangan hakim sebagai alat bukti dalam
kasus perkara No. Reg. Perk : PDS-01/SKRTA/Ft.1/03/2010. Pengertian saksi
mahkota dalam putusan Mahkamah Agung RI No.1986 K/Pid/1989 adalah teman
terdakwa yang dilakukan secara bersama-sama yang diajukan sebagai saksi untuk
membuktikan dakwaan penuntut umum dalam hal ini perkaranya dipisah
dikarenakan kurangnya alat bukti. Tetapi dalam perkembangannya di dalam
Putusan Mahkamah Agung RI No. 1174/K/Pid/1994 tanggal 3 Mei 1995, Putusan
Mahkamah Agung RI No. 1590/K/Pid/1995 tanggal 3 Mei 1995 dan Putusan
Mahkamah Agung RI No. 1592/K/Pid/1995 tanggal 3 Mei 1995 tidak
membenarkan adanya penggunaan saksi mahkota. Menurut putusan ini saksi
mahkota juga pelaku yang diajukan sebagai terdakwa dalam dakwaan yang
terpisah sehingga hal ini dianggap sebagai pelanggaran hak asasi terdakwa. Pada
kenyataannya dalam praktek peradilan di Indonesia masih sering digunakannya
saksi mahkota dalam mengatasi masalah kurangnya alat bukti saksi.

Hasil yang diperoleh dari penelitian ini yaitu bahwa selain dari Putusan
Mahkamah Agung RI tidak ada dasar hukum mengenai saksi mahkota dan
penggunaan
saksi
mahkota
dalam
perkara
No.Reg.Perk
:
PDS-
01/SKRTA/Ft.1/03/2010 berkait korupsi di Rumah Sakit Jiwa Daerah Surakarta
dibenarkan didasarkan pada prinsip-prinsip tertentu yaitu terdapat kekurangan alat
bukti, dalam perkara delik penyertaan (Deelneming), diperiksa dengan mekanisme
pemisahan (Splitsing). S aksi mahkota dalam kasus ini berkedudukan murni
sebagai saksi karena memenuhi syarat sebagai saksi sesuai Pasal 1 angka 26
KUHAP maka sah untuk dapat diperiksa sebagai saksi, sehingga majelis hakim
akan menerima dan mengakui kesaksian dari saksi mahkota ini dan akan digunakan
sebagai pertimbangkan dalam menyusun putusan.

Effects of Normative Aging on Eye Movements during Reading
Substantial progress has been made in understanding the mostly detrimental effects of normative aging on eye movements during reading. This article provides a review of research on aging effects on eye movements during reading for different writing systems (i.e., alphabetic systems like English compared to non-alphabetic systems like Chinese), focused on appraising the importance of visual and cognitive factors, considering key methodological issues, and identifying vital questions that need to be addressed and topics for further investigation
Enhancing staff attitudes, knowledge and skills in supporting the self-determination of adults with intellectual disability in residential settings in Hong Kong: A pretest-posttest comparison group design
Background: The ecological perspective recognizes the critical role that is played by rehabilitation personnel in helping people with intellectual disability (ID) to exercise self-determination, particularly in residential settings. In Hong Kong, the authors developed the first staff training programme of its kind to strengthen the competence of personnel in this area. The purpose of this study was to examine the effectiveness of staff training in enhancing residential staff's attitudes, knowledge and facilitation skills in assisting residents with ID to exercise self-determination. Methods: A pretest-posttest comparison group design was adopted. Thirty-two participants in an experimental group attended a six-session staff training programme. A 34-item self-constructed scale was designed and used for measuring the effectiveness of the staff training. Results: The results showed that the experimental group achieved statistically significant positive changes in all domains, whereas no significant changes were found in the comparison group. Conclusions: The findings provided initial evidence of the effectiveness of staff training that uses an interactional attitude-knowledge-skills model for Chinese rehabilitation personnel. The factors that contributed to its effectiveness were discussed and recommendations for future research were made. © Journal Compilation © 2007 Blackwell Publishing Ltd.postprin
Particle physics models of inflation
Inflation models are compared with observation on the assumption that the
curvature perturbation is generated from the vacuum fluctuation of the inflaton
field. The focus is on single-field models with canonical kinetic terms,
classified as small- medium- and large-field according to the variation of the
inflaton field while cosmological scales leave the horizon. Small-field models
are constructed according to the usual paradigm for beyond Standard Model
