Cryo‐EM Analysis of a Tri‐Heme Cytochrome‐Associated RC‐LH1 Complex from the Marine Photoheterotrophic Bacterium Dinoroseobacter Shibae

Advanced Science, EarlyView.
Cryo‐EM reveals a closed 17‐subunit LH ring encircling the RC‐LH1 complex in Dinoroseobacter shibae, featuring a novel helix‐turn‐helix subunit bridging RC and LH. Mg2⁺/Ca2⁺ stabilizes the complex, while periplasmic Cyt c₂ mediates electron transfer via a tri‐heme Cyt to the special pair of bacteriochlorophylls. Insights into energy/electron efficiency

PHELAN–MCDERMID SYNDROM (del 22q13 AND r(22)): LITERATURE REVIEW AND 2 CASE REPORTS

Русский журнал детской неврологии, 2017
Phelan–McDermid syndrome (PMS) is a microdeletion syndrome associated with the loss of terminal segments in chromosome 22, sometimes with development of the ring chromosome 22. Clinical manifestations of PMS include epilepsy and mental disorders (autism,

Single‐Cell Atlas Reveals Tumorigenic Profiles and Immune Dynamics of Adrenal Incidentalomas

Advanced Science, EarlyView.
Single‐cell RNA sequencing reveals cellular heterogeneity in adrenal incidentalomas, identifying distinct tumor cell populations. Clusterin is recognized as a biomarker for adrenocortical tumors, correlating with established markers. MYCN‐positive clusters in pheochromocytomas indicated poorer survival.

UGDH Lactylation Aggravates Osteoarthritis by Suppressing Glycosaminoglycan Synthesis and Orchestrating Nucleocytoplasmic Transport to Activate MAPK Signaling

Advanced Science, EarlyView.
Lactylation of UDP‐glucose dehydrogenase (UGDH) represses its enzymatic activity and causes glycosaminoglycans loss. In addition, UGDH lactylation facilitates its interaction with chromosome region maintenance 1 (CRM1) and promotes the nucleocytoplasmic transport.

Most Common Genetic Abnormality and Molecular Mutations on Human Sperm Y Chromosome and their Effects on Male Infertility

Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2014
BACKGROUND AND OBJECTIVE:Chromosomal or mitochondrial DNA abnormalities are the main causes of male infertility. So far, a lot of genes are identified on X and Y chromosomes that control the spermatogenesis process in a special order.

A Geometric Approach For Fully Automatic Chromosome Segmentation [PDF]

arXiv, 2011
A fundamental task in human chromosome analysis is chromosome segmentation. Segmentation plays an important role in chromosome karyotyping. The first step in segmentation is to remove intrusive objects such as stain debris and other noises. The next step is detection of touching and overlapping chromosomes, and the final step is separation of such ...

A Model of Epigenetic Inheritance Accounts for Unexpected Adaptation to Unforeseen Challenges

Advanced Science, EarlyView.
A general model of inheriting changes that are acquired during the lifetime of individuals demonstrates tremendous benefits to the population, including escape from extinction in changing environments. Contrasting the model with experimental data shows that inheritance of acquired changes enables rapid adaptation to unforeseen challenges, and accounts ...
