the condensation of glyoxal with benzylamine in the presence of formaldehyde leads to 2,4,6,8-tetrabenzyl-2,4,6,8-tetraazabicyclo [3.3.0] octan (6) in methanol. the scopes and limitations of the reaction have been determined. at low temperatures, a mixture of (6) and diol (7) is formed.

to evaluate the effects of accelerated aging and cold stress on seed germination and seedling growth indices in five oilseed rape cultivars (hyola330, hyola401, hyola420, syn3 and pr401/15e), an experiment was carried out in a completely randomized design of three replications. results indicated that the cultivars were significantly different in germination percentage, seed vigour, germination ...

Background. Nephrotic syndrome is caused by a variety of glomerulopathy. The current study investigated the renal histopathological spectrum of patients with nephrotic syndrome who received a renal biopsy in our department within the last 15 years. Methods. One thousand five hundred and twenty-three consecutive patients ( 14 years old at renal biopsy) with nephrotic syndrome were recruited. Pat...

Increased -synuclein ( syn) and mitochondrial dysfunction play central roles in the pathogenesis of Parkinson’s disease (PD), and lowering syn is under intensive investigation as a therapeutic strategy for PD. Increased syn levels disrupt mitochondria and impair respiration, while reduced syn protects against mitochondrial toxins, suggesting that interactions between syn and mitochondria influe...

Post-mortem analyses of brains from patients with Parkinson disease who received fetal mesencephalic transplants show that α-synuclein-containing (α-syn-containing) Lewy bodies gradually appear in grafted neurons. Here, we explored whether intercellular transfer of α-syn from host to graft, followed by seeding of α-syn aggregation in recipient neurons, can contribute to this phenomenon. We asse...

patients presenting with nephrotic syndrome with or without nephritic illness rarely come across with the diagnosis of ‘c1q nephropathy’. this entity is purely diagnosed with the help of immunofluorescence like iga nephropathy. clinical presentation is heterogenous, ranging from nephrotic range proteinuria to sub-nephrotic state; and with or without hematuria / renal insufficiency. similarly, t...

This paper presents a simple and robust mechanism called SYN-dog to sniff SYN flooding sources. We install SYN-dog as a software agent at leaf routers that connect stub networks to the Internet. The statelessness and low computation overhead of SYN-dog make itself immune to any flooding attacks. The core mechanism of SYN-dog is based on the protocol behavior of TCP SYN—SYN/ACK pairs, and is an ...

shwaehman syndrome, next to cystic fibrosis, is the second cause of congenita! exocrine pancreatic insufficiency in children. it appears as steatorrhea, recurrent infections and hematologic abnormalities such as neutropenia, skeletal dysplasia and short stature. in this study, we reviewed 3 patients' histories. all of them showed cellular chemotaxic defect. one of them had been affected by neph...

Extant and fossil genera and species in the Libytheinae (Nymphalidae) are revised and reviewed. The Libytheinae includes two genera: Libythea Fabricius and Libytheana Michener. Fifteen species and an additional 24 subspecies are recognized and 41 names are synonymized. Species recognized are: Libythea celtis (Laicharting), L. collenettei Riley, L. cinyras Trimen revised status, L. geoffroyi God...
