The deposition of salts in soil seems likely to become a significant barrier for plant development and growth. Halophytes that flourish naturally saline habitats may sustain extreme salt levels by adopting different acclimatory traits. Insight into such features can be useful devising salt-resilient crops the reclamation soil. Therefore, salinity-induced responses were studied two halophytes, i...
We demonstrate a monolithic optical whispering-gallery-mode resonator fabricated with barium fluoride (BaF₂) with an ultra-high quality (Q) factor above 10⁹ at 1550 nm, and measured with both the linewidth and cavity-ring-down methods. Vertical scanning optical profilometry shows that the root mean square surface roughness of 2 nm is achieved for our mm-size disk. To the best of our knowledge, ...
Accurate chromosome segregation in meiosis requires dynamic changes in chromatin organization. In Drosophila melanogaster, upon completion of recombination, meiotic chromosomes form a single, compact cluster called the karyosome in an enlarged oocyte nucleus. This clustering is also found in humans; however, the mechanisms underlying karyosome formation are not understood. In this study, we rep...
Prelamin A processing impairment is a common feature of a restricted group of rare genetic alterations/disorders associated with a wide range of clinical phenotypes. Changes in histone posttranslational modifications, alterations in non-histone chromatin proteins and chromatin disorganization have been specifically linked to impairment of specific, distinct prelamin A processing steps, but the ...
A inhibits caspase-independent death of NGF-deprived sympathetic neurons: a potential role for mitochondrial permeability transition.. pening of the permeability transition pore (PTP) has been implicated as an important mitochondrial event that occurs during apoptosis. We examined the role of the PTP in the well-characterized cell death of rat sympathetic neurons deprived of nerve growth factor...
We studied the effect of ba®lomycin A1 (Baf-A1), a novel and highly speci®c inhibitor for vacuolar-type proton (V-H) pump, on the growth of Japanese Encephalitis virus (JEV) in Vero cells. Viral ̄uorescence microscopic study showed that Baf-A1 induced the complete disappearance of acidi®ed compartments such as endosomes and lysosomes in Vero cells by the treatment with 0.1 mM Baf-A1 for 1 h at 3...
The nuclear lamina represents a protein network required for nuclear structure and function. One family of lamina proteins is defined by an approximately 40-aa LAP2, Emerin, and MAN1 (LEM) domain (LEM-D) that binds the nonspecific DNA-binding protein, barrier-to-autointegration factor (BAF). Through interactions with BAF, LEM-D proteins serve as a bridge between chromosomes and the nuclear enve...
BAF (Brg/Brm-associated factors) complexes play important roles in development and are linked to chromatin plasticity at selected genomic loci. Nevertheless, a full understanding of their role in development and chromatin remodeling has been hindered by the absence of mutants completely lacking BAF complexes. Here, we report that the loss of BAF155/BAF170 in double-conditional knockout (dcKO) m...
Bioaccumulation factors (BAFs) and biota-sediment accumulation factors (BSAFs) for phenanthrene, fluoranthene, pyrene, benz[a]anthracene, and chrysene/triphenylene were calculated using the tissue data of Zabik et al. for Salvelinus namaycush siscowet with a 20.5% lipid content, the water data of Baker and Eisenreich, and the sediment data of Baker and Eisenreich for the Lake Superior ecosystem...
In vivo, retroviral integration is mediated by a large nucleoprotein complex, termed the preintegration complex (PIC). PICs isolated from infected cells display in vitro integration activity. Here, we analyze the roles of different host cell factors in the structure and function of HIV type 1 (HIV-1) PICs. PICs purified by size exclusion after treatment with high salt lost their integration act...
