Aging and MPTP Sensitivity Depend on Molecular and Ultrastructural Signatures of Astroglia and Microglia in Mice Substantia Nigra.

Both astroglia and microglia show region-specific distribution in CNS and often maladapt to age-associated alterations within their niche. Studies on autopsied substantia nigra (SN) of Parkinson's disease (PD) patients and experimental models propose gliosis as a trigger for neuronal loss. Epidemiological studies propose an ethnic bias in PD prevalence, since Caucasians are more susceptible than non-whites.

Comparative evaluation of fracture resistance of wide and flared endodontically treated teeth with new techniques of postplacement - An study.

Aim: This study aims to compare and evaluate the fracture resistance of endodontically treated maxillary anterior teeth restored using new postplacement techniques.

Methodology: Forty-five single-rooted maxillary anterior teeth ( = 15) were selected and decoronated at the cementoenamel junction. The working length was determined using a 15K file.

Lattice Matching Anchoring of Hole-Selective Molecule on Halide Perovskite Surfaces for n-i-p Solar Cells.

Exploiting the self-assembled molecules (SAMs) as hole-selective contacts has been an effective strategy to improve the efficiency and long-term stability of perovskite solar cells (PSCs). Currently, research works are focusing on constructing SAMs on metal oxide surfaces in p-i-n PSCs, but realizing a stable and dense SAM contact on halide perovskite surfaces in n-i-p PSCs is still challenging. In this work, the hole-selective molecule for n-i-p device is developed featuring a terephthalic methylammonium core structure that possesses double-site anchoring ability and a matching diameter (6.

Genome Sequence of Phage .

Phage JanetJ was isolated on and has siphovirus morphology. JanetJ's genome consists of 36,986 base pairs, encoding 52 putative protein-coding genes. JanetJ adds to the small number of previously isolated cluster FO phages, none of which encode identifiable immunity repressor or integrase functions, with the exception of phage Maja.
